Universal Reconfigurable Diffractive Photonic Chip for Multi‐Modal Optical Computing

ABSTRACT Optical computing represents a transformative hardware paradigm for the post‐Moore era, exploiting its inherent advantages of high speed, low power consumption, and intrinsic parallelism. Nonetheless, state‐of‐the‐art integrated optical computing systems suffer from crit...

MXene‐Confined Cobalt‐Rich Co 2 P Nanoparticles Enable Highly Reversible Conversion Reaction for Stable and Fast Sodium‐Ion Batteries

ABSTRACT Transition metal phosphides have attracted considerable attention as alternative conversion‐type anodes for SIBs because of their high specific capacities. However, their sodium‐storage mechanism typically shifts to an alloying reaction between P and Na + after the initi...

The Role of Information and Communications Technology in Mitigating Loneliness among Older Adults in Deprived Neighborhoods: Introducing a Digital Lens for Aging in Place

Neighborhood deprivation functions as an environmental stress that undermines aging in place by revealing geographic disparities, unmet needs, and resource shortages. Revisiting the context–person framework, this study highlights two components that foster positive aging outcomes...

A closed-loop calibrated digital twin for vibration suppression and performance enhancement of the milking robot manipulator

The Automatic Milking System (AMS) has significantly improved dairy farming efficiency. However, residual vibrations generated by the high-speed motion of the milking manipulator continue to pose significant challenges, particularly by compromising positioning accuracy and cup at...

AI-Enhanced Tools in Interpreting Practice: A Systematic Review of Methodological Trends and Empirical Evidence

Interpreting is undergoing substantial transformation with the advent of artificial intelligence (AI)-enhanced tools. While empirical research examining their effects has proliferated, review evidence from a methodological perspective remains limited. This systematic review synth...

The Evolution of Metal Halide Perovskite Transistors

ABSTRACT Metal halide perovskites (MHPs) offer a revolutionary pathway for next‐generation field‐effect transistors (FETs) because of their exceptional carrier mobilities and cost‐effective processability. However, their transition to practical electronics is significantly challe...

To swear or not to swear: a quantitative study of swearword translation in Dave Chappelle’s stand-up comedy

Generating data from 1,130 swearword instances from Dave Chappelle’s eight original English Netflix specials and their official Chinese subtitles, this study adopts a quantitative approach to examine shifts in perceived offensiveness after swearwords were translated, the employme...

Immediate spinal and paraspinal muscle responses to Schroth Method exercises in adolescent idiopathic scoliosis: a real-time three-dimensional ultrasonography study

To quantify immediate, real-time changes in three-dimensional spinal alignment and paravertebral muscle parameters during the performance of a single Schroth posture using three-dimensional ultrasonography.This study further aimed to provide an objective, real-time assessment of...

scProtoTransformer: Scalable reference mapping across molecules, cells, and donors

Abstract The rapid accumulation of single-cell data has made it possible to comprehensively characterize biological systems at molecular, cellular, and donor levels. However, scalable reference mapping across different resolutions remains a major challenge in current research. He...

Tail Dependence: The Impact of Risk Spillovers on Real Estate Markets in Times of Economic and Geo‐Political Uncertainty

ABSTRACT The first half of the 2020's has seen a degree of economic and geo‐political uncertainty not observed since the 1970s. This paper looks at how listed real estate is exposed to capital market shocks by estimating Conditional Value‐at‐Risk (CoVaR), which captures the sensi...

Tunnel field-effect transistors exhibiting performance beyond the Boltzmann thermionic limit

The International Roadmap for Devices and Systems (IRDS) has identified the tunnel field-effect transistor (TFET) as the most promising next-generation logic device that enables sustainable downscaling in driving voltage and power consumption. Demonstrating an acceptable sub–Bolt...

Developing a Novel Grading System for Building Health Assessment

Abstract Urban decay in many cities, including Hong Kong, has been exacerbated by aging buildings and building neglect. Proper maintenance is essential to ensure building safety and health. A building assessment is necessary to evaluate building conditions, helping stakeholders m...

Cross-Cultural Scenario Benchmark: Evaluating LLMs’ Cross-Cultural Understanding

Cross-cultural reasoning and alignment have been identified as key weaknesses of large language models (LLMs), but the architectural or cognitive features underlying these failures have not been adequately examined. In addition, previous studies rely almost exclusively on dataset...

Thermal cycling–induced nitriding increases energy-storage density in titanate ferroelectric films

Enhancing dielectric energy-storage density ( U e ) requires maximizing the difference between maximum and remanent polarizations (Δ P ). Improving Δ P remains fundamentally challenging, as existing strategies rarely achieve simultaneous high maximum polarization and low remanent...

Autophagy in the Regulation of Placental Development: From Trophoblast Differentiation to Metabolic Stress Adaptation

Successful pregnancy depends on precise placental development, where trophoblast differentiation, syncytialization, invasion, and adaptation to metabolic stress are critical. Autophagy, a lysosome-mediated degradation pathway, has emerged as an important regulator of cellular hom...

Oral Nanomicelle‐Mediated Sequential Butyrate Production in the Intestine for Ulcerative Colitis and Immunosuppression Treatment

ABSTRACT Butyrate (BA) is essential for intestinal health, but its intestinal therapeutic applications are hindered by its malodorous nature, premature gastric absorption, and rapid intestinal metabolism. To address these challenges, an inodorous macromolecule β‐glucan‐BA (GLU‐BA...

Rare Variants May Influence Disease Risk and Clinical Features in Sporadic Late-Onset Chinese Parkinson’s Disease Patients

BackgroundThe heritability in Parkinson’s disease (PD) may be contributed by rare variants (RVs) in candidate genes. Currently there is limited genetic data on Chinese PD patients.ObjectiveWe aim to identify RVs in Chinese PD patients and investigate their relationships with risk...

Service Systems with On-Demand and Reserved Servers

Problem definition: In many real-world applications, such as cloud computing, there is a growing trend to supplement long-term reserved capacity with short-term on-demand capacity. We study a queueing system that employs both reserved and (relatively more expensive) on-demand ser...
