Control of Chain Transfer by Tailored Metal–Phenyl π ‐Interactions in Bis(Imino)Pyridyl Cobalt‐Catalyzed Ethylene Polymerization

ABSTRACT In bis(imino)pyridyl iron/cobalt‐catalyzed ethylene polymerization, broad and bimodal molecular weight distributions of polyethylenes (PEs) are often produced because of two different chain transfer pathways. In this paper, a combined theoretical and experimental study d...

Sex-Specific Plasma Proteomic Alterations Underpin Distinct COVID-19 Progression and Post-COVID-19 Condition

Abstract Sex differences in COVID-19 and its sequelae remain poorly understood, which hinders targeted therapies. We performed plasma proteomic analyses of 69 hospitalized patients with COVID-19 and 30 healthy controls from a prospective Chinese cohort. The UK Biobank and Mount S...

GKR-Spike: A Cross-Attention Enhanced Hybrid SNN via Gaussian Kernel Density Estimation and Key-Residual Frames for AIoT

Device-free fall detection using Wi-Fi Channel State Information (CSI) is promising for pervasive health monitoring but is impeded by environmental dependency and a high computational cost. While deep learning (DL) methods can automatically extract features, computationally expen...

An expert routing-driven graph framework from tongue multi-task features to liver fibrosis prediction

Liver fibrosis is a global health concern where early detection is crucial for timely intervention. Traditional Chinese Medicine tongue diagnosis offers a promising non-invasive assessment, but suffers from inter-observer variability and subjective interpretation. Current artific...

Effect of geometric protrusions and depressions on critical heat flux density of the heating surface

In the “Melted Reactor Retention and External Pressure Vessel Cooling (IVR-ERVC)” strategy for nuclear power plants, the Critical Heat Flux (CHF) serves as the critical limit for ensuring pressure vessel integrity. Traditional safety assessment procedures rely on an ideal flat su...

Peritumoral Malignant Cellular Foci Performs Better Than Tumor Budding and Poorly Differentiated Cluster in Risk Stratification of Lymph Node Metastasis in pT1 Colorectal Cancer

As biomarkers separated by the arbitrary 5-tumor-cell cutoff at the tumor invasive front, tumor budding (TB) and poorly differentiated clusters (PDC) are recognized as high-risk factors for lymph node metastasis (LNM) in pT1 colorectal cancer (CRC). Nonetheless, relevant findings...

Nonnegative Ricci curvature, Euclidean volume growth, and the fundamental groups of open 4-manifolds

Abstract Let 𝑀 be a 4-dimensional open manifold with nonnegative Ricci curvature. In this paper, we prove that if the universal cover of 𝑀 has Euclidean volume growth, then the fundamental group π 1 ⁢ ( M ) \pi_{1}(M) is finitely generated. This result confirms Pan–Rong’s conject...

High‐Resolution Temperature and Precipitation Variability in Northeast Asia Since the Last Glacial Maximum Recorded in an Annually Laminated Maar Lake

Abstract Temperature and precipitation variability in monsoonal Asia is central to understanding regional climate dynamics and global teleconnections. How post‐LGM warming and hydroclimate change unfolded in Northeast Asia, and how they were linked to external forcing, remain poo...

Structure-Stress Engineering for Controllable Integration of ZnO Nanowires in Gated Field Emitter Arrays

Gated field-emission arrays (FEAs) based on nanowires have significant applications in vacuum microelectronic devices. Controllable integration of nanowires in microstructures is a key issue to be solved in gated FEAs. Structural design is a general strategy for stress redistribu...

Plant invasions are associated with lower community stability at multiple spatial scales

Plant invasions are threatening the long-term sustainability of ecosystem functions. Yet, how plant invasions impact the temporal stability of community cover across spatial scales remains poorly understood, hindering effective invasion management. Using the National Ecological O...

Unraveling the spatial heterogeneity of pre-summer extreme rainfall regimes in South China using multi-dimensional joint clustering

Abstract The temporal evolutions of extreme rainfall (ER) events are highly dynamic. In addition, the destructive potential of ERs is fundamentally governed by multi-dimensional metrics, including rainfall accumulation, event duration, and intra-event rain-rate evolution. However...

Defect engineering of oxygen vacancies and domain configuration for high-performance CaBi 4 Ti 4 O 15 piezoelectric ceramics

Abstract Bismuth-layer-structured ferroelectrics (BLSFs) are promising candidates for high-temperature piezoelectric applications owing to their intrinsically high Curie temperatures. However, their practical implementation is hindered by the relatively low piezoelectric activity...

Targeting MDA5 induces immunogenic cell death and promotes anti-tumor immunity

Identifying targets to enhance tumor immunity is an urgent need. Although nucleic acid sensors play critical roles in promoting tumor immune clearance, their exceptionally low mutation rate in cancers suggests potential unexplored roles in tumor progression. Here, we demonstrate...

Synergy of Solid-State NMR and Dielectric Spectroscopy Reveals Synchronized Multi-Rotor Dynamics in Crystalline Supramolecular Gyroscopes

Abstract Understanding the correlated dynamics of multiple molecular rotators in crystalline supramolecular assemblies is essential for designing functional molecular machines, yet deconvoluting the motions of distinct components remains inherently challenging due to the limitati...
