• Convergent synthetic approaches to polycyclic aromatic dicarboximides. Shoyama, Kazutaka; Würthner, Frank (2025). 12(1) 328–345.

  Polycyclic aromatic dicarboximides (PADIs) as represented by naphthalene and perylene bis(dicarboximides) are useful molecules for a variety of functional materials and remain important synthetic targets for organic chemists. In this review, we summarize recent developments in the convergent synthetic approaches using palladium-catalysed annulation of peri-activated naphthalimides. Contrary to conventional linear synthetic methods where a single starting material is converted into a target molecule through a stepwise manner, the herein discussed convergent synthetic method enables rapid extension of the π-scaffold by combining multiple polyaromatic substrates into one. This method opened new possibilities for π-extended dicarboximides with so far up to five imide groups. Further exploration of annulation strategies may allow the preparation of previously inaccessible PADIs with fascinating molecular and material properties.
• Trapped in the Matrix: Algorithmic Control and Worker Dispossession in the African Platform Economy. Dinika, Adio-Adet (2025). 5(1)

  Digital labor platforms are reshaping the work landscape in Sub-Saharan Africa, promising enhanced productivity and empowerment. Yet, this study reveals a more complex reality, particularly in Rwanda, South Africa, and Zimbabwe. Based on 41 in-depth interviews, it exposes how algorithmic management systems deeply erode worker autonomy, highlighting significant financial, task, and behavioral dispossession. This research, grounded in neo-Marxist and postcolonial theories, scrutinizes the nuanced limitations of autonomy and the pervasive control exerted by algorithmic management, reflecting the lived experiences of workers. The findings illuminate enduring patterns of accumulation that echo historical exploitation, maintaining asymmetric power dynamics and dependence. Despite this, the study captures the agency of workers as they navigate and resist these systemic constraints, challenging the dominant techno-optimistic narrative. It underscores the critical need for contextually informed empirical research to shape policies that champion equity and elevate marginalized voices during transformative economic shifts.

• Gezonde leefgewoonten en het vermijden van risicofactoren. Mangtep (2024).

  Het vermijden van roken en overmatig alcoholgebruik is cruciaal voor de gezondheid van de prostaat. Het roken van sigaretten wordt in verband gebracht met een hoger risico op het ontwikkelen van prostaatkanker, dus het is belangrijk om deze verslaving te voorkomen. Overmatig alcoholgebruik kan ook een negatieve invloed hebben op de gezondheid van de prostaat. Het onder controle houden van uw gewicht door middel van een gezond dieet en regelmatige lichaamsbeweging is belangrijk voor het behoud van een gezonde prostaat. Het verminderen van stress en het behouden van het mentale evenwicht hebben ook een positief effect op de gezondheid van de prostaat. Educatie en bewustzijn De rol van voorlichting en bewustwording is uiterst belangrijk bij het voorkomen van prostaataandoeningen. Bewustmakingscampagnes over de gezondheid van de prostaat en preventieve programma's zijn belangrijk om het publiek bewust te maken van het belang van regelmatige onderzoeken en een gezonde levensstijl. Vroegtijdige detectie van prostaatziekten is cruciaal voor een effectieve behandeling en verbeterde therapeutische resultaten. Daarom moet publieke voorlichting over de gezondheid van de prostaat een prioriteit zijn.
• Een gezond dieet voor de gezondheid van de prostaat. Mangtep (2024).

  Een gezond dieet speelt een sleutelrol bij het behouden van de gezondheid van de prostaat. Fruit, groenten en vezels zijn essentieel voor het goed functioneren van de prostaat. Voedingsstoffen zoals lycopeen (te vinden in tomaten), vitamine E (te vinden in noten en zaden) en zink (te vinden in zeevruchten en pompoenpitten) hebben een gunstig effect op de gezondheid van de prostaat. U moet bewerkte voedingsmiddelen, vet voedsel en overmatige consumptie van rood vlees vermijden, omdat dit het risico op prostaataandoeningen kan vergroten. Regelmatige fysieke activiteit Regelmatige fysieke activiteit heeft veel voordelen voor de gezondheid van de prostaat. Het regelmatig uitvoeren van aërobe oefeningen, zoals joggen, fietsen of wandelen, verbetert de bloedcirculatie, versterkt de spieren en kan ook het risico op prostaataandoeningen verminderen. Te veel tijd doorbrengen met zitten kan het risico op prostaatproblemen vergroten, dus het is belangrijk om een ​​actieve levensstijl te leiden en regelmatig aan lichaamsbeweging te doen.

(2024). 2300968.

  Lithium niobate (LNO) and lithium tantalate (LTO) see widespread use in fundamental research and commercial technologies reaching from electronics over classical optics to integrated quantum communication. The mixed crystal system lithium niobate tantalate (LNT) allows for the dedicate engineering of material properties by combining the advantages of the two parental materials LNO and LTO. Vibrational spectroscopies such as Raman spectroscopy or (Fourier transform) infrared (IR) spectroscopy are vital techniques to provide detailed insight into the material properties, which is central to the analysis and optimization of devices. This work presents a joint experimental?theoretical approach allowing to unambiguously assign the spectral features in the LNT material family through both Raman and IR spectroscopy, as well as providing an in-depth explanation for the observed scattering efficiencies based on first-principles calculations. The phononic contribution to the static dielectric tensor is calculated from the experimental and theoretical data using the generalized Lyddane?Sachs?Teller relation and compared with the results of the first-principles calculations.
• Network model for magnetic higher-order topological phases. Liu, Hui; Moghaddam, Ali G.; Varjas, Daniel; Fulga, Ion Cosma (2024). 6(4) 043167.

  We propose a network-model realization of magnetic higher-order topological phases (HOTPs) in the presence of the combined space-time symmetry C4T -- the product of a fourfold rotation and time-reversal symmetry. We show that the system possesses two types of HOTPs. The first type, analogous to Floquet topology, generates a total of 8 corner modes at 0 or π eigenphase, while the second type, hidden behind a weak topological phase, yields a unique phase with 8 corner modes at ±π/2 eigenphase (after gapping out the counterpropagating edge states), arising from the product of particle-hole and phase rotation symmetry. By using a bulk Z4 topological index (Q), we found both HOTPs have Q=2, whereas Q=0 for the trivial and the conventional weak topological phase. Together with a Z2 topological index associated with the reflection matrix, we are able to fully distinguish all phases. Our work motivates further studies on magnetic topological phases and symmetry protected 2π/n boundary modes, as well as suggests that such phases may find their experimental realization in coupled-ring-resonator networks.
• Dielectric relaxation in the quantum multiferroics Rb\($_\mathbf2$\)⁢Cu\($_\mathbf2$\)⁢Mo\($_\mathbf3$\)⁢⁢O\($_\mathbf12$\)⁢ and Cs\($_\mathbf2$\)⁢Cu\($_\mathbf2$\)⁢Mo\($_\mathbf3$\)⁢⁢O\($_\mathbf12$\)⁢.

  Motivated by the recent discovery of dielectric relaxation by quantum critical magnons in Cs2Cu2Mo3O12, we conduct a detailed analysis of its dielectric response and compare it to that in the isostructural compound Rb2Cu2Mo3O12. Measurements in the vicinity of the field-induced magnon softening show that its description in terms of 3D Bose-Einstein condensation of magnons quantum critical point is unaltered by the presence of dielectric relaxation. We also demonstrate the existence of dielectric relaxation anomalies at 19 K in Rb2Cu2Mo3O12 and discuss the implications for the microscopic origin of dielectric activity in two compounds.
• Entanglement smectic and stripe order. Chakraborty, Nilotpal; Moessner, Roderich; Doucot, Benoit (2024). 133(20) 206604.

  Spontaneous symmetry breaking and more recently entanglement are two cornerstones of quantum matter. We introduce the notion of anisotropic entanglement ordered phases, where the spatial profile of spin-pseudospin entanglement spontaneously lowers the four-fold rotational symmetry of the underlying crystal to a two-fold one, while the charge density retains the full symmetry. The resulting phases, which we term entanglement smectic and entanglement stripe, exhibit a rich Goldstone mode spectrum and a set of phase transitions as a function of underlying anisotropies. We discuss experimental consequences of such anisotropic entanglement phases distinguishing them from more conventional charge or spin stripes. Our discussion of this interplay between entanglement and spontaneous symmetry breaking focuses on multicomponent quantum Hall systems realizing textured Wigner crystals, as may occur in graphene or possibly also in moiré systems, highlighting the rich landscape and properties of possible entanglement ordered phases.
• Synthesis, crystal growth, structure and photophysical properties of decafluoroanthracene and its co-crystals with polycyclic arenes. Friedrich, Alexandra; Schraut-May, Lisa; Rauch, Florian; Durand, Pablo; Krebs, Johannes; Ruth, Paul N.; Hammer, Sebastian; Bertermann, Rüdiger; Finze, Maik; Clark, Stewart J.; Pflaum, Jens; Leclerc, Nicolas; Marder, Todd B. (2024).

  A series of 1 : 1 co-crystals of decafluoroanthracene with naphthalene, anthracene, tetracene, pyrene, perylene, and triphenylene were grown and characterised using single-crystal X-ray diffraction at low and ambient temperature, (polarisation-dependent) fluorescence spectroscopy, and quantum mechanical computations. All of the molecular co-crystal structures are built from infinite stacks of alternating arene and decafluoroanthracene molecules representing the arene–perfluoroarene supramolecular synthon. Intermolecular interactions and packing features are discussed in detail. As a by-product, the heterodimer of tetracene and decafluoroanthracene was obtained after exposure to room light or under UV-irradiation of a solution of the monomers, and was structurally characterised. The fluorescence properties of the co-crystals of decafluoroanthracene with naphthalene, tetracene, pyrene, perylene, and triphenylene are similar to those of one of their components with only a small bathochromic or hypsochromic shift. This shows that the interaction between the components is weak and fits well into the picture of an arene–perfluoroarene interaction. An exception is 1 : 1 anthracene : decafluoroanthracene, which shows a bathochromic shift of both excitation and especially emission spectra of the co-crystal compared to those of its components, which indicates weak charge transfer coupling in the ground state followed by an exciplex-like emission.
• Grain boundary engineering enhances the thermoelectric properties of Y\($_\mathbf2$\)Te\($_\mathbf3$\). Rahman, Jamil Ur; Guo, Shuping; Pérez, Nicolás; Jang, Kyuseon; Jung, Chanwon; Ying, Pingjun; Scheu, Christina; Zavanelli, Duncan; Zhang, Siyuan; Sotnikov, Andrei; Snyder, Gerald Jeffrey; van den Brink, Jeroen; Nielsch, Kornelius; He, Ran (2024). 2404243.

  Abstract The performance of thermoelectric materials is typically assessed using the dimensionless figure of merit, zT. Increasing zT is challenging due to the intricate relationships between electrical and thermal transport properties. This study focuses on Y2Te3-based thermoelectric materials, which are predicted to be promising for high-temperature applications due to their inherently low lattice thermal conductivity. A series of Y2+xTe3 compositions with excess Y is synthesized to explore the effects on electronic and structural characteristics. Density functional theory calculations suggest that additional Y atoms increase charge carriers, thereby enhancing electrical conductivity and boosting thermoelectric performance. X-ray diffraction analysis reveals that the presence of excess Y reduces lattice volume and alters bonding structures. Furthermore, the addition of Bi significantly enhances the power factor by promoting the segregation of elemental Bi particles and the formation of Y-Bi-rich grain boundaries, which improve weighted mobility. This microstructural optimization leads to a fourfold increase in the Seebeck coefficient, resulting in a peak zT of 1.23 at 973 K and a predicted maximum conversion efficiency of 10.3% under a temperature difference of 673 K. These findings highlight the potential of Y2Te3 for high-temperature thermoelectric applications and demonstrate the effectiveness of grain boundary engineering in enhancing thermoelectric performance.

• [111]-strained spin ice: Localization of thermodynamically deconfined monopoles. Lu, Zhongling; Schäfer, Robin; Hallén, Jonathan N.; Laumann, Chris R. (2024). 110(18) 184421.

  We study classical spin ice under uniaxial strain along the [111] crystallographic axis. Remarkably, such strain preserves the extensive ice degeneracy and the corresponding classical Coulomb phase. The emergent monopole excitations remain thermodynamically deconfined exactly as in the isotropic case. However, their motion under local heat bath dynamics depends qualitatively on the sign of the strain. In the low-temperature limit for negative strain, the monopoles diffuse, while for positive strain, they localize. Introducing additional ring exchange dynamics into the ice background transforms the localized monopoles into sub-dimensional excitations whose motion is restricted to diffusion in the (111)-plane. The phenomena we identify are experimentally accessible in rare-earth pyrochlores under uniaxial pressure as well as in tripod kagome materials. The diffusive versus localized nature of the monopoles manifests in characteristic magnetic noise spectra, which we compute.
• Adding a twist to the loops: the role of DNA superhelicity in the organization of chromosomes by SMC protein complexes. Valdés, Antonio; Haering, Christian H. (2024). 52(6) 2487–2497.

  Structural maintenance of chromosomes (SMC) protein complexes, including cohesin, condensin, and the Smc5/6 complex, are integral to various processes in chromosome biology. Despite their distinct roles, these complexes share two key properties: the ability to extrude DNA into large loop structures and the capacity to alter the superhelicity of the DNA double helix. In this review, we explore the influence of eukaryotic SMC complexes on DNA topology, debate its potential physiological function, and discuss new structural insights that may explain how these complexes mediate changes in DNA topology.
• Bond disorder in extended Heisenberg-Kitaev models: Spin textures and in-gap states in the high-field regime. Fragkopoulou, Georgia; Vojta, Matthias (2024). 110(17) 174444.

  We study the effect of bond disorder in extended Heisenberg-Kitaev models on the honeycomb lattice, relevant for materials such as α-RuCl3, in the semiclassical limit using a combination of T-matrix and real-space spin-wave approaches. Focusing on the regime of large applied magnetic field, we discuss two distinct but related disorder-induced phenomena, namely spin textures in the vicinity of isolated impurities and magnetic excitations below the bulk gap. A finite impurity concentration smears the field-tuned phase transition and turns the isolated in-gap states into impurity bands. As a result, there is a large field regime above the bulk transition into the high-field phase where impurity-induced states fill the bulk spin gap. We illustrate the field dependence of these in-gap states for parameters relevant for α-RuCl3, and we connect our results to heat-transport and NMR data which indicated their presence.
• Lack of near-sightedness principle in non-Hermitian systems. Spring, Helene; Könye, Viktor; Akhmerov, Anton R.; Fulga, Ion Cosma (2024). 17 153.

  The non-Hermitian skin effect is a phenomenon in which an extensive number of states accumulates at the boundaries of a system. It has been associated to nontrivial topology, with nonzero bulk invariants predicting its appearance and its position in real space. Here, we demonstrate that the non-Hermitian skin effect has weaker bulk-edge correspondence than topological insulators: when translation symmetry is broken by a single non-Hermitian impurity, skin modes are depleted at the boundary and accumulate at the impurity site, without changing any bulk invariant. Similarly, a single non-Hermitian impurity may deplete the states from a region of Hermitian bulk.

• Surface superconductivity in the topological Weyl semimetal t-PtBi\($_\mathbf2$\).

  Topological superconductivity is a promising concept for generating fault-tolerant qubits. Early experimental studies looked at hybrid systems and doped intrinsic topological or superconducting materials at very low temperatures. However, higher critical temperatures are indispensable for technological exploitation. Recent angle-resolved photoemission spectroscopy results have revealed that superconductivity in the type-I Weyl semimetal—trigonal PtBi2 (t-PtBi2)—is located at the Fermi-arc surface states, which renders the material a potential candidate for intrinsic topological superconductivity. Here we show, using scanning tunnelling microscopy and spectroscopy, that t-PtBi2 presents surface superconductivity at elevated temperatures (5 K). The gap magnitude is elusive: it is spatially inhomogeneous and spans from 0 to 20 meV. In particular, the large gap value and the shape of the quasiparticle excitation spectrum resemble the phenomenology of high-Tc superconductors. To our knowledge, this is the largest superconducting gap so far measured in a topological material. Moreover, we show that the superconducting state at 5 K persists in magnetic fields up to 12 T.
• Wide-field Kerr microscopy and magnetometry on Cr\($_\mathbf2$\)Ge\($_\mathbf2$\)Te\($_\mathbf6$\) exfoliated van-der-Waals flakes. Soldatov, Ivan; Özer, Burak; Aswartham, Saicharan; Selter, Sebastian; Veyrat, Louis; Büchner, Bernd; Schäfer, Rudolf (2024). 12 181025–181040.

  The potential of wide-field magneto-optical Kerr microscopy for the characterisation of low-dimensional van-der-Waals crystals is explored using the example of Cr2Ge2Te6 flakes in the ten nanometers thickness range. Although the magnetic domains with an expected width in the hundred-nanometer range cannot be seen on this material due to the limited lateral resolution, we show that Kerr microscopy is nevertheless a very valuable method for measuring the magnetization loops on selectable thickness regions on the flake. From the loop character one can indirectly infer on the existence or suppression of band domains, which are the equilibrium patterns above a film thickness of about 7nm. We derived this characteristic thickness from the initial susceptibility of the hysteresis loops and used it to estimate the specific domain wall energy to be 2.7⋅10−4 J/m2. We further demonstrate a thickness- and light colour dependent sign inversion of the Kerr signal that is explained by a Fresnel-type depth sensitivity concept. Accordingly, the Kerr contrast is governed by the relative phase of the Kerr amplitude that can be freely adjusted by a rotatable compensator. The compensator is thus the decisive optical element in magneto-optical Kerr magnetometry and microscopy on low-dimensional materials. It needs to be appropriately aligned to avoid a cancelation of the Kerr contrast and to maximise the Kerr signal.
• Geometrically taming dynamical entanglement growth in purified quantum states. Pokart, Tim; Lehmann, Carl; Budich, Jan Carl (2024). 110(24) 245109.

  Entanglement properties of purified quantum states are of key interest for two reasons. First, in quantum information theory, minimally entangled purified states define the Entanglement of Purification as a fundamental measure for the complexity of the corresponding physical mixed state. Second, dynamical entanglement growth in purified states represents the main bottleneck for calculating dynamical physical properties on classical computers in the framework of tensor network states. Here, we demonstrate how geometric methods including parallel transport may be harnessed to reduce such dynamical entanglement growth, and to obtain a general prescription for maintaining (locally) optimal entanglement entropy when time-evolving a purified state. Adapting and extending by higher order skew corrections the notion of Uhlmann geometric phases, we reveal the relation between dynamical entanglement growth and the geometry of the Hilbert-Schmidt bundle as the mathematical foundation of purified states. With benchmarks on a non-integrable spin chain model, we compare the computational performance of matrix product state algorithms based on our present geometric disentangling method to previous approaches for taming entanglement growth in purified states. Our findings provide numerical evidence that geometric disentanglers are a powerful approach, superior in various aspects to known methods for disentangling purified states in a range of physically relevant computational scenarios. To exclude the effect of algorithmic imperfections, we also provide a numerically exact analysis for systems of moderate size.

• Application of Stone-Derived Substrates in Thin-Film Temperature Sensing. Saeedzadeh Khaanghah, Niloofar; Oliveira, Hugo de Souza; Krik, Soufiane; Carrasco-Pena, Alejandro; Cantarella, Giuseppe; Haller, Michael; Rapagnani, Nicholas; Bezooijen, Aart van; Nippa, Michael; Münzenrieder, Niko (2024). 24(24) 40179–40187.

  Advancements in materials and technologies have enabled thin-film electronics to be directly developed on previously unsuitable substrates. This article explores the fabrication of two thin-film temperature sensors, thermistors, and resistance temperature detectors (RTDs), using stone-based substrates, including marble, brick, stone paper, and Limex paper. The thermistors and RTDs were fabricated utilizing Cu/InGaZnO and Zn, applying the sputtering deposition technique. The sensor’s performance was analyzed based on two different heating methodologies: one using a hotplate, and the other using localized heating from above. The sensors’ performance was characterized within a temperature range of \($25~^\circ $\) C– \($80~^\circ $\) C. While the marble thermistor demonstrated the highest sensitivity among all thermistors at −11.54% \($^\circ \text C^-1$\) , the stone paper RTD similarly showed the highest sensitivity among all RTDs at 0.064% \($^\circ \text C^-1$\) . The localized heating methodology on top of RTDs resulted in the stone paper and Limex showing negligible hysteresis. Moreover, the sensors demonstrated stable behavior in the multiple reliability tests. Furthermore, Zn-based RTDs were dissolvable in less than 36 h. The outcomes show that stone-based materials are promising natural eco-friendly substrates for temperature sensors leading to less hazardous electronic waste.
• LiST: An All-Linear-Layer Spatial-Temporal Feature Extractor with Uncertainty Estimation for RUL Prediction. Huang, Zhixin; Gruhl, Christian; Sick, Bernhard (2024). 1–7.

  In the context of Remaining Useful Life (RUL) prediction for industrial systems, the pursuit of prediction accuracy must be balanced against the hardware costs of model operation and the reliability of prediction results. To resolve these challenges, we introduce LiST, an all-linear-layer spatial-temporal feature extractor integrated with uncertainty estimation, specifically designed for processing sensor multivariate time series (MTS) data. Unlike traditional linear models that flatten MTS and thus neglect their spatial-temporal dependencies, LiST's linear layers act on both the sensor and time dimensions of MTS that can extract spatial and temporal features like GNN and RNN models. Through performance comparisons on four RUL prediction datasets, LiST uses only 66.1% of the parameters, achieves comparable accuracy to state-of-the-art GNN and RNN models, obtains the best results on two datasets with up to a 21.6% improvement in Score, and enhances training efficiency by 3.2 times. Additionally, LiST can predict RUL with uncertainty estimation and precisely disentangle epistemic and aleatoric uncertainties, thus enhancing the model's practicality and reliability in real-world industrial applications.
• Time-Series Representation Learning via Heterogeneous Spatial-Temporal Contrasting for Remaining Useful Life Prediction. Huang, Zhixin; He, Yujiang; Nivarthi, Chandana Priya; Gruhl, Christian; Sick, Bernhard (2024). 1–21.

  Classical contrastive learning paradigms rely on manual augmentations like cropping, masking, dropping, or adding noise randomly to create divergent sample views from original data. However, the choice of which method to manipulate samples is often subjective and may destroy the latent pattern of the sample. In response, this paper introduces a novel contrastive learning paradigm without choosing sample view augmentation methods, termed Heterogeneous Spatial-Temporal Representation Contrasting (HSTRC). Instead of sample view augmentation, we employ dual branches with a heterogeneous spatial-temporal flipped structure to extract two distinct hidden feature views from the same source data, which avoids disturbing the original time series. Leveraging a combination of cross-branch spatial-temporal contrastive and projected feature contrastive loss functions, HSTRC can effectively extract robust representations from unlabeled time series data. Remarkably, by only fine-tuning the fully connected layers on top of extracted representations by HSTRC, we achieve the best performance across several Remaining Useful Life prediction datasets, showing up to 19.2% improvements over the state-of-the-art supervised learning methods and classical contrastive learning paradigms. Besides, further intensive experiments demonstrate HSTRC's effectiveness in active learning, out-of-distribution testing, and transfer learning scenarios.
• Steering Towards Maritime Safety with True Motion Predictions Ensemble. Al-Falouji, Ghassan; Beyer, Tom; Gao, Shang; Tomforde, Sven (2024). 7–12.

  Maritime transportation is vital for global trade, yet safety challenges persist, especially with increasing vessel density and narrow waterways. The standard Closest Point of Approach (CPA) method, used to estimate collision risk, has limitations due to its reliance on constant Course Over Ground (COG) and Speed Over Ground (SOG) assumptions, neglecting dynamic vessel behaviours, true ship dimensions, and environmental influences. Addressing these limitations, this paper introduces an enhanced CPA (eCPA) method that counters these deficits by incorporating ship trajectory predictions, probabilistic risk assessment, and real-time data integration. The eCPA method includes user- adjustable tools for trajectory interpolation, prediction, and anomaly elimination, making it adaptable to various maritime scenarios. Extensive testing in encounter scenarios demonstrates the effectiveness of our approach in improving maritime safety through robust and probabilistic estimation of encounter points. This method aligns with the Self-Integration and Self-Organising Systems (SISSY) initiative, exhibiting how autonomous maritime operations can benefit from self-improving and self-integrating systems to enhance navigation safety and efficiency.

• Interaction-correlated random matrices. Saberi, Abbas Ali; Saber, Sina; Moessner, Roderich (2024). 110(18) L180102.

  We introduce a family of random matrices where correlations between matrix elements are induced via interaction-derived Boltzmann factors. Varying these yields access to different ensembles. We find a universal scaling behavior of the finite-size statistics characterized by a heavy-tailed eigenvalue distribution whose extremes are governed by the Fréchet extreme value distribution for the case corresponding to a ferromagnetic Ising transition. The introduction of a finite density of nonlocal interactions restores standard random-matrix behavior. Suitably rescaled average extremes, playing a physical role as an order parameter, can thus discriminate aspects of the interaction structure; they also yield further nonuniversal information. In particular, the link between maximum eigenvalues and order parameters offers a potential route to resolving long-standing problems in statistical physics, such as deriving the exact magnetization scaling function in the two-dimensional Ising model at criticality.

• Activiteit na het werk – mentaal comfort is ook belangrijk. Mangtep (2024).

  Fysieke problemen zijn één ding, maar onze psyche is net zo belangrijk. Intellectueel werk kan ook vermoeiend zijn voor het lichaam. Vooral als we gestrest zijn vanwege te veel verantwoordelijkheden. Om deze reden kunt u constante fysieke activiteit overwegen. Sommige mensen houden van hardlopen, anderen geven de voorkeur aan teamsporten. In grotere steden zijn tennis of squash populair. Tijdens het sporten kunnen we ‘oefenen’ en ontstressen. Daarnaast zorgen wij ook voor een betere conditie en conditie. Mensen die dagelijks aan een bureau werken, hebben vaak een gebrek aan beweging. Daarom is het de moeite waard om na te denken over hoe u voor uw lichaam moet zorgen. Als sport niets voor ons is, kunnen we besluiten om elke dag langere wandelingen te maken.

Er zijn echter veel soorten therapie en de arts is verantwoordelijk voor de juiste selectie ervan. Welke psychotherapeutische trends zijn te onderscheiden? Wanneer moet je naar een psychotherapeut en wanneer naar een psycholoog? Trends in psychotherapie Psychotherapie maakt gebruik van verschillende werkmethoden, die, afhankelijk van de aard van het probleem, voor verschillende mensen zijn bedoeld. Een van de meest populaire typen is de cognitief-gedragsmatige trend. Het richt zich primair op het identificeren van de basis van verontrustende reacties en het veranderen van disfunctionele overtuigingen die het dagelijks functioneren negatief beïnvloeden. Het wordt aanbevolen voor mensen die worstelen met stemmingsstoornissen, depressie of bipolaire stoornis. Poradnia Harmonia houdt zich onder meer bezig met dit soort psychotherapie . We onderscheiden ook systemische psychotherapie, waarbij de stoornissen van één persoon worden beschouwd in de context van interpersoonlijke relaties. Vaak zijn er meerdere mensen bij betrokken, omdat het vooral gebaseerd is op de opvatting dat de mens in verschillende systemen functioneert. Het is meestal het doelwit van degenen die de situatie in hun gezin of relatie willen verbeteren. Als u psychische problemen ervaart, kan een psychotherapeut u helpen. Consultaties in Warschau (maar ook online!) worden uitgevoerd door de ervaren medewerkers van de Harmonia Clinic. Ook de psychodynamische therapie, die vooral gebaseerd is op de psychoanalyse, verdient aandacht. De nadruk ligt op de rol van het onderbewustzijn bij het functioneren - wat we niet in onszelf accepteren en onopgeloste conflicten zijn vaak de oorzaak van stoornissen of moeilijkheden in relaties. Ook onderscheiden we onder andere de humanistische, Gestalt- en psychoanalytische stromingen.
• Hoe zorg je voor je gezondheid?. Mangtep (2024).

  Elke taak heeft zijn eigen specificiteit. Maar zelfs als u vele uren zit, is het de moeite waard om elk uur op te staan ​​en te bewegen. Een paar eenvoudige rekoefeningen kunnen voorkomen dat ons lichaam na het werk stijf aanvoelt. Als we tijdens het werken lange tijd naar het beeldscherm staren, is het de moeite waard om passende ondersteuning voor onze ogen te overwegen. Denk hierbij aan een speciale bril die de impact van blauw licht op de ogen vermindert. Dankzij dit zullen onze ogen na het werk niet zo moe zijn. Laten we ook letten op hoe we zitten. In tegenstelling tot wat het lijkt, kan een onjuiste houding achter de computer ernstige problemen veroorzaken. Laten we daarom de stoel goed afstellen, zodat onze benen een comfortabele houding kunnen aannemen.
• Psycholoog of psychotherapeut?. Mangtep (2024).

  Als u een crisis doormaakt of onmiddellijke ondersteuning nodig heeft, zal een goede psycholoog in Warschau van de Harmonia Clinic u helpen. Het is de moeite waard om naar een psychotherapeut te gaan als je kampt met terugkerende, diepere mentale problemen, verstoorde patronen en reacties die lang aanhouden. Met hem samenwerken is langdurig en draagt ​​bij aan een betere zelfkennis. Bedenk dat het zoeken naar hulp wanneer u moeilijkheden ervaart, een teken is van moed en bereidheid om te veranderen – en niet van zwakte. Hierdoor heeft u de mogelijkheid om de kwaliteit van uw leven te verbeteren, uw relaties met uw dierbaren te verbeteren en de problemen waarmee u worstelt te overwinnen.
• Regelmatige prostaatonderzoeken en preventie. Mangtep (2024).

  Regelmatige prostaatonderzoeken, zoals prostaatpalpatie en het testen van PSA-waarden (prostaatspecifiek antigeen), zijn cruciaal voor de vroege detectie van prostaatziekten, waaronder prostaatkanker. Richtlijnen voor de testfrequentie variëren afhankelijk van leeftijd en risicofactoren. Regelmatige controle van de conditie van de prostaat zorgt ervoor dat u snel actie kunt ondernemen als er afwijkingen worden geconstateerd. Preventie, zoals een gezonde voeding en levensstijl, speelt ook een belangrijke rol bij het voorkomen van prostaataandoeningen.
• Kinderosteopathie - is het de moeite waard om te gebruiken?. Mangtep (2024).

  Kinderosteopathie is een specialisme binnen het vakgebied osteopathie dat zich richt op het diagnosticeren en behandelen van diverse aandoeningen bij zuigelingen en kinderen. Osteopathie, als holistische benadering van gezondheid, is gebaseerd op de overtuiging dat alle delen van het lichaam nauw met elkaar verbonden zijn en elkaar beïnvloeden. In de medische wereld, waar technologie en farmacologie voorop lopen in de vooruitgang, is er een groeiend begrip van een holistische benadering van gezondheid en welzijn. Eén van deze benaderingen is osteopathie – een vorm van alternatieve geneeskunde die zich richt op de manuele behandeling en manipulatie van het bewegingsapparaat, zenuwen en zachte weefsels. Dit is vooral belangrijk in de context van kinderosteopathie, waar specialisten zoals Agnieszka Łoś van OsteoMedic een sleutelrol spelen. Kinderosteopathie omvat een breed scala aan manuele technieken - van zachte spierontspanningstechnieken en gewrichtsmanipulatie tot specifieke technieken gericht op specifieke delen van het lichaam, zoals het hoofd, de wervelkolom of de ledematen. Daarnaast hebben kinderosteopaten kennis en ervaring met de specifieke ontwikkeling van kinderen in verschillende stadia, waardoor zij ontwikkelingsproblemen effectief kunnen diagnosticeren en behandelen. Gezondheidsproblemen die behandeld kunnen worden met kinderosteopathie zijn onder meer koliek, eetproblemen, slaapproblemen, chronische oorinfecties en problemen met evenwicht en coördinatie. Bovendien kan kinderosteopathie een effectieve aanvulling zijn op de traditionele medische zorg voor kinderen met chronische ziekten of handicaps. Het is echter belangrijk om te onthouden dat pediatrische osteopathie alleen mag worden beoefend door gekwalificeerde professionals die over de juiste ervaring en kennis beschikken van de anatomie en fysiologie van een kind.
• Kantoorwerk: hoe zorg je elke dag voor je gezondheid als je een zittend beroep hebt?. Mangtep (2024).

  Kantoorwerk wordt als gemakkelijker beschouwd dan fysiek werk. Toch kunnen we, zelfs als we aan een bureau zitten, last krijgen van onnodige gezondheidsproblemen. Hoe zorg je voor je gezondheid? Waar moet u op letten bij zittend werken? De werkplek zelf is belangrijk. Onze positie moet goed georganiseerd zijn. Een stoel en een monitor zullen bijzonder belangrijk zijn. Bij een stoel moet deze een comfortabele rugleuning hebben en in hoogte verstelbaar zijn door middel van een draaimechanisme. Laten we ervoor zorgen dat onze ogen recht naar de monitor gericht zijn. Als we moeten bukken om naar het scherm te kijken, kunnen we op termijn last krijgen van nekpijn.
• Prostaatgezondheid: belangrijke stappen in het welzijn van mannen. Mangtep (2024).

  De rol van de prostaat en het belang ervan voor de gezondheid van mannen De prostaat is een klier die alleen bij mannen voorkomt en die belangrijke functies vervult in het urogenitale systeem. Het is verantwoordelijk voor de productie van vocht dat deel uitmaakt van sperma. Een gezonde prostaat is cruciaal voor het goed functioneren van het urogenitale systeem. Prostaatproblemen kunnen een negatieve invloed hebben op de algehele gezondheid van mannen, dus het is belangrijk om voor de gezondheid van uw prostaat te zorgen.

  Abstract Biodiversity monitoring is an almost inconceivable challenge at the scale of the entire Earth. The current (and soon to be flown) generation of spaceborne and airborne optical sensors (i.e., imaging spectrometers) can collect detailed information at unprecedented spatial, temporal, and spectral resolutions. These new data streams are preceded by a revolution in modeling and analytics that can utilize the richness of these datasets to measure a wide range of plant traits, community composition, and ecosystem functions. At the heart of this framework for monitoring plant biodiversity is the idea of remotely identifying species by making use of the ‘spectral species’ concept. In theory, the spectral species concept can be defined as a species characterized by a unique spectral signature and thus remotely detectable within pixel units of a spectral image. In reality, depending on spatial resolution, pixels may contain several species which renders species-specific assignment of spectral information more challenging. The aim of this paper is to review the spectral species concept and relate it to underlying ecological principles, while also discussing the complexities, challenges and opportunities to apply this concept given current and future scientific advances in remote sensing.

  Abstract The field of landscape genetics has been rapidly evolving, adopting and adapting analytical frameworks to address research questions. Current studies are increasingly using regression-based frameworks to infer the individual contributions of landscape and habitat variables on genetic differentiation. This paper outlines appropriate and inappropriate uses of multiple regression for these purposes, and demonstrates through simulation the limitations of different analytical frameworks for making correct inference. Of particular concern are recent studies seeking to explain genetic differences by fitting regression models with effective distance variables calculated independently on separate landscape resistance surfaces. When moving across the landscape, organisms cannot respond independently and uniquely to habitat and landscape features. Analyses seeking to understand how landscape features affect gene flow should model a single conductance or resistance surface as a parameterized function of relevant spatial covariates, and estimate the values of these parameters by linking a single set of resistance distances to observed genetic dissimilarity via a loss function. While this loss function may involve a regression-like step, the associated nuisance parameters are not interpretable in terms of organismal movement and should not be conflated with what is actually of interest: the mapping between spatial covariates and conductance/resistance. The growth and evolution of landscape genetics as a field has been rapid and exciting. It is the goal of this paper to highlight past missteps and demonstrate limitations of current approaches to ensure that future use of regression models will appropriately consider the process being modeled, which will provide clarity to model interpretation.
• THE IMPACT OF ASPECT RATIO ON THE BEHAVIOUR OF RIGID WATER STORAGE TANKS. Helou, Samir H. (2021). 11(1)

  Ubiquitous reinforced concrete water storage tanks are quite popular and widely used in Palestine as in elsewhere in the world; they form pivotal components of major bulk-water carrier systems. In essence, they form lifelines to many communities; the water storage concept is as old as civilization itself. Location and land availability often dictate the topology of the tank’s structure. They may be either shallow and stubby or deep yet slender or anywhere in between having an aspect ratio dictated by overall site conditions. In all cases adequate structural analysis is mandatory.

• Towards Computer Aided Diagnosis of Autism Spectrum Disorder Using Virtual Environments. Roth, Daniel; Jording, Mathis; Schmee, Tobias; Kullmann, Peter; Navab, Nassir; Vogeley, Kai (2020). 115–122.

  Autism Spectrum Disorders (ASD) are neurodevelopmental disorders that are associated with characteristic difficulties to express and interpret nonverbal behavior, such as social gaze behavior. The state of the art in diagnosis is the clinical interview that is time intensive for the clinicians and does not take into account any objective measures of behavior. We herewith propose an empirical approach that can potentially support diagnosis based on the assessment of nonverbal behavior in avatar-mediated interactions in virtual environments. In a first study, ASD individuals and a typically developed control group were interacting in dyads. Head motion, and eye gaze of both interlocutors were recorded, replicated to the avatars and displayed to the partner through a distributed virtual environment. The nonverbal behavior of both interaction partners was recorded, and resulting preprocessed data was classified with up to 92.9parcent classification accuracy, with the amount of eye area focus and the average horizontal gaze change being the most relevant features. We expect that such systems could improve the diagnostic assessment on the basis of objective measures of nonverbal behavior.

• An Efficient Method For Online Identification Of Steady State For Multivariate System. Technical Report (190), Xu, Honglun None (2018).

  Most of the existing steady state detection approaches are designed for univariate signals. For multivariate signals, the univariate approach is often applied to each process variable and the system is claimed to be steady once all signals are steady, which is computationally inefficient and also not accurate. The article proposes an efficient online method for multivariate steady state detection. It estimates the covariance matrices using two different approaches, namely, the mean- squared-deviation and mean-squared-successive-difference. To avoid the usage of a moving window, the process means and the two covariance matrices are calculated recursively through exponentially weighted moving average. A likelihood ratio test is developed to compare the difference of the two covariance matrices and to detect the steady state. The intensive numerical studies and real case study show that the proposed method can accurately detect the steady state of a multivariate system.

By means of prevailing hard security mechanisms, security goals like authentication, authorization, privacy, non repudiation of services and other hard security issues are resolved. But these mechanisms fail to provide soft security. An exhaustive survey of existing trust and reputation models in P2P network regarding service provisioning is presented and challenges are listed. Trust issues like trust bootstrapping, trust evidence procurement, trust assessment, trust interaction outcome evaluation and other trust based classification of peer’s behavior into trusted,, inconsistent, un trusted, malicious, betraying, redemptive are discussed.
• Dropout: a simple way to prevent neural networks from overfitting. Srivastava, Nitish; Hinton, Geoffrey; Krizhevsky, Alex; Sutskever, Ilya; Salakhutdinov, Ruslan (2014). 15(1) 1929–1958.

  Deep neural nets with a large number of parameters are very powerful machine learning systems. However, overfitting is a serious problem in such networks. Large networks are also slow to use, making it difficult to deal with overfitting by combining the predictions of many different large neural nets at test time. Dropout is a technique for addressing this problem. The key idea is to randomly drop units (along with their connections) from the neural network during training. This prevents units from co-adapting too much. During training, dropout samples from an exponential number of different "thinned" networks. At test time, it is easy to approximate the effect of averaging the predictions of all these thinned networks by simply using a single unthinned network that has smaller weights. This significantly reduces overfitting and gives major improvements over other regularization methods. We show that dropout improves the performance of neural networks on supervised learning tasks in vision, speech recognition, document classification and computational biology, obtaining state-of-the-art results on many benchmark data sets.
