The role of the PKCζ/JNK signaling pathway in regulating the development of femoral head necrosis.

Osteonecrosis of the femoral head (ONFH) is a debilitating condition characterized by the death of bone cells in the hip joint, resulting in profound disability. This condition has a significant global prevalence. Glucocorticoid (GC)-induced apoptosis of bone cells serves as a crucial cellular mechanism underlying ONFH.

What Causes Bilateral Pleural Effusion: A Case Report.

Early diagnosis and treatment have very important clinical significance.

Case Summary: We present a case of an 82-year-old man with a known history of hypertension who was admitted for pleural effusion.

Proton-Conducting Hydrogen-Bonded Framework of a Cobalt(II) Single-Ion Magnet Sulfonate.

Diamagnetic metal sulfonates have been widely reported, while paramagnetic species are very rare, especially those that exhibit interesting magnetic and/or proton conduction properties. Herein, we report the synthesis, structure, magnetic, and proton-conducting properties of a hydrogen-bonded cobalt(II) organosulfonate complex. The coordination self-assembly of Co salts and 8-quinolinesulfonic acid ligands affords a mononuclear Co sulfonate featuring both coordinated and noncoordinated sulfonic acid O atoms and axial coordinated water molecules.

Bose-Einstein condensation of a two-magnon bound state in a spin-1 triangular lattice.

In ordered magnets, the elementary excitations are spin waves (magnons), which obey Bose-Einstein statistics. Similarly to Cooper pairs in superconductors, magnons can be paired into bound states under attractive interactions. The Zeeman coupling to a magnetic field is able to tune the particle density through a quantum critical point, beyond which a 'hidden order' is predicted to exist.

Extremely low lattice thermal conductivity in light-element solid materials.

Lattice thermal conductivity ( ) is of great importance in basic sciences and in energy conversion applications. However, low- crystalline materials have only been obtained from heavy elements, which typically exhibit poor stability and possible toxicity. Thus, low- materials composed of light elements should be explored.

Momentum-Direct Infrared Interlayer Exciton and Photodetection in Multilayer van der Waals Heterostructures.

Interlayer excitons (IX), spatially separated electron-hole pair quasiparticles, can form in type-II van der Waals heterostructures (vdWH). To date, the most widely studied IX in hetero- and homobilayer transition metal dichalcogenides feature momentum-indirect and visible interlayer recombinations. However, momentum-direct IX emissions and interlayer absorptions, especially in the infrared, are crucial for excitonic devices but remain underexplored.

Metalo Hydrogen-Bonded Organic Frameworks Constructed by Coordinated Chains for Magnetic and Proton-Conductive Bifunctionality.

Metalo hydrogen-bonded organic frameworks (MHOFs) have received growing interest in designing crystalline functional materials. However, reports on bifunctional MHOFs showing magnetic and proton-conductive properties are extremely limited and their design is challenging. Herein, we investigated the magnetic and proton-conductive properties of two sulfonated and , {M(HO)(abs)} (M = Co and Mn, Habs = 4-aminoazobenzene-4'-sulfonic anion), constructed by coordination chains.

Uncovering the phonon spectra and lattice dynamics of plastically deformable InSe van der Waals crystals.

Stacking two-dimensional (2D) van der Waals (vdW) materials in a layered bulk structure provides an appealing platform for the emergence of exotic physical properties. As a vdW crystal with exceptional plasticity, InSe offers the opportunity to explore various effects arising from the coupling of its peculiar mechanical behaviors and other physical properties. Here, we employ neutron scattering techniques to investigate the correlations of plastic interlayer slip, lattice anharmonicity, and thermal transport in InSe crystals.

Comparing experience- and description-based economic preferences across 11 countries.

Recent evidence indicates that reward value encoding in humans is highly context dependent, leading to suboptimal decisions in some cases, but whether this computational constraint on valuation is a shared feature of human cognition remains unknown. Here we studied the behaviour of n = 561 individuals from 11 countries of markedly different socioeconomic and cultural makeup. Our findings show that context sensitivity was present in all 11 countries.

Adaptive recognition of machining features in sheet metal parts based on a graph class-incremental learning strategy.

The integration of computer-aided design (CAD), computer-aided process planning (CAPP), and computer-aided manufacturing (CAM) systems is significantly enhanced by employing deep learning-based automatic feature recognition (AFR) methods. These methods outperform traditional, rule-based approaches, particularly in handling the complexities of intersecting features. However, existing deep learning-based AFR methods face two major challenges.

Topological Electronic Transition Contributing to Improved Thermoelectric Performance in p-Type MgSb Bi Solid Solutions.

Topological electronic transition is the very promising strategy for achieving high band degeneracy (N) and for optimizing thermoelectric performance. Herein, this work verifies in p-type MgSb Bi that topological electronic transition could be the key mechanism responsible for elevating the N of valence band edge from 1 to 6, leading to much improved thermoelectric performance. Through comprehensive spectroscopy characterizations and theoretical calculations of electronic structures, the topological electronic transition from trivial semiconductor is unambiguously demonstrated to topological semimetal of MgSb Bi with increasing the Bi content, due to the strong spin-orbit coupling of Bi and the band inversion.

We analyzed the literature on different apicomplexan micropores and found that T.

The graph representation of complex materials plays a crucial role in the field of inorganic and organic materials investigations for developing data-centric materials science, such as those using graph neural networks (GNNs). However, the currently prevalent GNN models are primarily employed for investigating periodic crystals and organic small molecule data, yet they still encounter challenges in terms of interpretability and computational efficiency when applied to polymer monomers and organic macromolecules data. There is still a lack of graph representation of organic polymers and macromolecules specifically tailored for GNN models to explore the structural characteristics.

Searching for new high-performance thermoelectric (TE) materials that are economical and environmentally friendly is an urgent task for TE society, but the advancements are greatly limited by the time-consuming and high cost of the traditional trial-and-error method. The significant progress achieved in the computing hardware, efficient computing methods, advance artificial intelligence algorithms, and rapidly growing material data have brought a paradigm shift in the investigation of TE materials. Many electrical and thermal performance descriptors are proposed and efficient high-throughput (HTP) calculation methods are developed with the purpose to quickly screen new potential TE materials from the material databases.

Interlayer Phonon Coupling from Heavy and Light Sublayers in a Natural Van der Waals Superlattice.

Layered compounds characterized by van der Waals gaps are often associated with relatively weak interlayer particle interactions. However, in specific scenarios, these seemingly feeble forces can exert an impact on interlayer interactions through subtle energy fluctuations, which can give rise to a diverse range of physical and chemical properties, particularly intriguing in the context of thermal transport. In this study, taking a natural superlattice composed of alternately stacked PbS and SnS sublayers as a model, we proposed that in a superlattice, there is strong hybridization between acoustic phonons of heavy sublayers and optical phonons of light sublayers.
