Targeting the NR1D1–IGF2BP2–V-ATPase Axis With Hybrid Nanovesicles Restores Macrophage Rhythms to Reverse Sepsis-Induced Immunosuppression
1 Introduction Sepsis is a life-threatening syndrome of organ dysfunction caused by a dysregulated host response to infection and remains a leading cause of infection-related mortality worldwide [1].
Quantitative evaluation and optimization of long-term care insurance policy texts in pilot cities of Guangxi Zhuang autonomous region
Abstract Objective: To systematically evaluate the quality and internal consistency of the long-term care insurance (LTCI) policy documents in five pilot cities of Guangxi Zhuang Autonomous Region, explore the allocation structure of policy instruments and the interaction pattern of stakeholders, and identify the strengths and weaknesses of the policy system. Methods: A total of nine core policy documents from five cities including Hezhou, Nanning, Liuzhou, Beihai and Guigang were collected.
Coupled dual-channel memristors for hardware-native trustworthy Bayesian intelligence
Abstract Bayesian neural networks (BNNs) enable trustworthy edge intelligence by quantifying predictive uncertainty. However, hardware BNN implementations face a bottleneck: digital approaches suffer from high latency, while memristors are limited by the intrinsic coupling between their conductance state (mean) and stochastic noise (variance). Here we report a coupled dual-channel memristor (CDCM) based on an ion gel/ZnO heterostructure that breaks this fundamental trade-off.
Study on plasma exosome miRNA sequencing and analysis in rats under hemorrhagic stress
Abstract This study explored the impact of hemorrhagic stress on the expression of plasma exosome miRNAs in rats using high-throughput miRNA sequencing technology. The results revealed that hemorrhagic stress significantly altered the expression profiles of multiple miRNAs, particularly the upregulation of miRNA-193b-3p, which is associated with vascular repair, and the downregulation of miRNA-485-5p, which may be related to impaired cell repair and antioxidant responses.

Molecular-dipole oriented universal growth of conjugated polymers into semiconducting single-crystal thin films - Nature Communications
Abstract Precise control over crystallinity and morphology of conjugated polymers (CPs) is essential for progressing organic electronics. However, manufacturing single-crystal thin films of CPs presents substantial challenges due to their complex molecular structures, distorted chain conformations, and unbalanced crystallization kinetics.
Monolayer Molecular Crystal Field-effect Transistors: Advances and Perspectives
Monolayer Molecular Crystal Field-effect Transistors: Advances and Perspectives To break the limitations of traditional molecular materials in electronic devices, especially in organic field-effect transistors (OFETs), developing monolayer molecular crystals (MMCs) with the ultimate thickness is crucial: 1) the ultra-thin thickness of MMCs could reduce the contact resistance and result in high-efficiency charge carrier injection, which can improve device performance and facilitate the...
Biomimetic nanocluster photoreceptors for adaptative circular polarization vision - Nature Communications
Abstract Nanoclusters with atomically precise structures and discrete energy levels are considered as nanoscale semiconductors for artificial intelligence. However, nanocluster electronic engineering and optoelectronic behavior have remained obscure and unexplored. Hence, we create nanocluster photoreceptors inspired by mantis shrimp visual systems to satisfy the needs of compact but multi-task vision hardware and explore the photo-induced electronic transport.
Strain-restricted transfer of ferromagnetic electrodes for constructing reproducibly superior-quality spintronic devices - Nature Communications
Abstract Spintronic device is the fundamental platform for spin-related academic and practical studies. However, conventional techniques with energetic deposition or boorish transfer of ferromagnetic metal inevitably introduce uncontrollable damage and undesired contamination in various spin-transport-channel materials, leading to partially attenuated and widely distributed spintronic device performances.
Lysosomal-associated protein transmembrane 5 ameliorates non-alcoholic steatohepatitis by promoting the degradation of CDC42 in mice - Nature Communications
Our results demonstrated that LAPTM5 could be ubiquitination degraded by NEDD4L under metabolic stresses. Overexpression of LAPTM5 attenuated liver steatosis, inflammatory response, and fibrosis. Mechanistically, LAPTM5 can directly bind to CDC42, promotes its lysosomal degradation, and then inhibit the activation of c-Jun NH2-terminal kinase signaling pathway, thus serving its function. Hepatocyte LAPTM5 is a promising therapeutic target for NASH.
YOLO-SASE: An Improved YOLO Algorithm for the Small Targets in Complex Backgrounds
3.3. Contrast Test of Network Structure To evaluate the detection effect of infrared small targets, average precision (AP), average recall (AR), and frame per second (FPS) were used as evaluation indexes. To verify the effectiveness and reliability of the proposed detection algorithm, the experiment was divided into three parts: overall effect comparison, module improvement comparison, and ablation experiment. Original infrared images were used in the training set.
Organic donor-acceptor heterojunctions for high performance circularly polarized light detection - Nature Communications
Abstract Development of highly efficient and stable lateral organic circularly polarized light photodetector is a fundamental prerequisite for realization of circularly polarized light integrated applications. However, chiral semiconductors with helical structure are usually found with intrinsically low field-effect mobilities, which becomes a bottleneck for high-performance and multi-wavelength circularly polarized light detection.

Bottom-up growth of n-type monolayer molecular crystals on polymeric substrate for optoelectronic device applications
It is well known that organic semiconductors usually grow on SiO -based substrates in a step-like, layer-by-layer growth mode25,26,27. In order to construct MMCs, the candidate molecules should have strong molecular interactions and orientation in 2D (not just 1D) within the intralayer, while a weak force along the interlayer direction is required to suppress the nucleation and growth of a second layer (Supplementary Fig. 1).
Short-Wave Near-Infrared Linear Dichroism of Two-Dimensional Germanium Selenide
Polarized detection has been brought into operation for optics applications in the visible band. Meanwhile, an advanced requirement in short-wave near-infrared (SW-NIR) (700–1100 nm) is proposed. Typical IV–VI chalcogenides—2D GeSe with anisotropic layered orthorhombic structure and narrow 1.1–1.2 eV band gap—potentially meets the demand. Here we report the unusual angle dependences of Raman spectra on high-quality GeSe crystals.
Organic semiconductor crystals
Organic semiconductors have attracted a lot of attention since the discovery of highly doped conductive polymers, due to the potential application in field-effect transistors (OFETs), light-emitting diodes (OLEDs) and photovoltaic cells (OPVs). Single crystals of organic semiconductors are particularly intriguing because they are free of grain boundaries and have long-range periodic order as well as minimal traps and defects.
