Regeneration-aware online SOH estimation framework for liquid metal batteries based on fragmented data

Liquid metal batteries (LMBs) are regarded as a promising candidate for grid energy storage, owing to their long lifespan and high safety. However, their accurate state of health (SOH) estimation is significantly hindered by the prevalence of fragmented data and the pronounced ca...

How Heat Stress Mediates the Impacts of Street-level Environmental Features on Housing Prices: A Comparative Study of Center City and Outside Areas in Philadelphia

Urban heat increasingly shapes housing markets, but existing studies often use coarse data and overlook spatial differences. This study develops an SEM-centered framework, with RF-SHAP as a non-parametric robustness check, to examine how 1-meter Universal Thermal Climate Index (U...

In Situ Formation of a Hybrid Alloy‐Fluoride Interphase for Stable High‐Capacity Phosphorus Anodes

ABSTRACT Phosphorus‐based anodes are promising candidates for next‐generation high‐energy‐density lithium‐ion batteries owing to their high theoretical capacity. However, their practical application is severely limited by drastic volume variation and unstable solid electrolyte in...

Wafer-scale low-symmetry graphene moiré superlattice for integrated quantum rectifiers

Low-symmetry materials unlock rich Berry curvature physics and anomalous transport phenomena that are forbidden in high-symmetry quantum systems through rigorous crystalline symmetry constraints. Current approaches rely on external fields or complex heterogeneous stacking to brea...

Improved YOLOv11 Framework with Channel Attention for High-Precision Identification of Luffa Leaf Diseases

Early accurate identification of luffa crop diseases is essential for timely treatment and high-quality agricultural production. Currently, luffa disease diagnosis relies solely on manual field inspection, which is labor-intensive and error-prone, and lacks assessment uniformity....

Discovering nominal constructions through behavioral profiles: the case of Akan

This study examines nominal constructions in Asante Twi, a variety of Akan (Niger-Congo, Kwa), using the Behavioral Profiles (BP) approach. It investigates how constructional identification can be operationalized empirically, and what taxonomy of noun phrase (NP) patterns emerges...

Semi-analytical modeling and experimental measurement of elastic thermal expansion and aspect-ratio effects in Cu/SiO2 vias for 3D IC integration

Thermally induced protrusion of Cu pads embedded in SiO 2 vias is important for fine-pitch Cu/SiO 2 hybrid bonding, but its dependence on via geometry remains incompletely quantified. In this work, in situ heating atomic force microscopy (AFM) measurements at 25 and 200 °C are co...

FramePoison: attacks on medical RAG that target framing, not just facts

Retrieval-augmented generation (RAG) is increasingly used in high-stakes domains like medicine, where answers are grounded in retrieved literature and can shape clinical understanding. This opens a new attack surface: an adversary can shape model outputs by injecting a few docume...

Traffic congestion control for ARZ model with an arbitrarily large input delay

This paper addresses the stabilisation problem for Aw-Rascle-Zhang (ARZ) traffic model in the presence of an arbitrarily large input delay. The linearised ARZ model is a 2×2 hyperbolic partial differential equation (PDE) system with proximal reflection, which introduces significa...

Indispensable Interphase Passivation in Solvation‐Regulated Propylene Carbonate Electrolytes for Ah‐Level Lithium‐Ion Batteries at −50–120°C

ABSTRACT Propylene carbonate (PC) is a high‐permittivity, wide‐temperature solvent, but the Li + ‐PC co‐intercalation issue in graphite (Gr) anode curtailed its application in lithium‐ion batteries. Although solvation engineering suppresses co‐intercalation, long‐term cycling is...

Chiral Phosphoserine Reconfigures the Energy Conversion Pathway for Efficient and Stable Sequentially Deposited Perovskite Solar Cells

ABSTRACT FAPbI 3 perovskite solar cells (PSCs) fabricated via sequential deposition hold great promise for high photovoltaic performance. However, two bottlenecks remain persistent: transport‐limited conversion that leaves residual PbI 2 and the high thermal prerequisite to drive...

Thermally Reversible Transformation between Two Isomers of Silver Sulfide Magic-Size Clusters

Abstract Isomers of semiconductor magic-size clusters (MSCs) share the same molecular formula but can exhibit distinct optical and electronic properties. Most of the reported MSC isomers have been so far limited to cadmium chalcogenides. Herein, we report the reversible transform...

Metal-Free Carbon with Synergistic Enrichment Catalysis for Rapid Removal of Antibiotics

Abstract A freeze-drying-assisted pyrolysis strategy was used to prepare nitrogen-doped porous carbon (FNC800) from glucose and dicyandiamide (600–900 °C). FNC800 possessed hierarchical porosity (specific surface area 747.36 m2 g–1) and pyridinic-N sites. After 30 min adsorption–...

Learning to Simulate: Generative Metamodeling via Quantile Regression

Stochastic simulation models effectively capture complex system dynamics but are often too slow for real-time decision making. Traditional metamodeling techniques learn relationships between simulator inputs and a single output summary statistic, such as the mean or median. These...

PSHIC reveals allele-specific chromatin organization by phasing-free structural modeling

Resolving the distinct 3D chromatin architectures of parental chromosomes is critical for understanding diploid genome function, but many haplotype-resolved Hi-C contact-map methods remain constrained by their reliance on phased single-nucleotide polymorphisms (SNPs). This depend...

Temperature-dependent behavior of polymer latex in calcium sulfoaluminate cement: critical role of glass transition temperature

Polymer latex modification is highly temperature-sensitive in cement-based systems, yet its governing mechanisms remain unclear, particularly under sub-zero conditions. This study systematically investigates the temperature-dependent behavior of a controlled model polymer‑calcium...

Additive manufacturing of heterostructured metallic materials: Processing, microstructural characteristics, mechanical properties, and service performance

Developing high-performance metallic materials with excellent mechanical properties and reliable service performance is an everlasting objective of materials research. The perspective on heterostructured materials with dramatic differences in compositions and structures, in conju...

Complete Ectogenesis, Parental Love, and Human Flourishing: A Confucian Critique

Abstract Complete ectogenesis (CE), if technologically realized, would portend a radical decoupling of fetal development from the female body, thereby dismantling the biological and cultural nexus between gestation and kinship. This paper argues that a Confucian approach offers a...

A Survey of Robotic Navigation and Manipulation with Physics Simulators in the Era of Embodied AI

Navigation and manipulation are core capabilities in Embodied AI, but training agents to perform them directly in the real world is costly, time-consuming, and unsafe. Therefore, sim-to-real transfer has emerged as a key approach, yet the sim-to-real gap persists. This survey exa...

Contamination Means Overestimation? A Fine-Grained Empirical Study in Code Intelligence

In recent years, code intelligence has gained increasing importance in the field of automated software engineering. Meanwhile, the widespread adoption of Pretrained Language Models (PLMs) and Large Language Models (LLMs) has raised concerns regarding data contamination and its po...
