Lu+ optical frequency references with accuracy verified at the 19th digit

Optical atomic frequency references1 have far surpassed their microwave frequency predecessors, leading to an anticipated redefinition of the SI (International System of Units) second2. However, as the scientific community seeks consensus on a new standard, and several state-of-t...

Alleviating Linguistic and Interactional Anxiety of Non-Native Speakers in Multilingual Communication

Non-native speakers (NNSs) frequently encounter speaking difficulties in multilingual communication, where existing approaches have shown promise in facilitating NNSs’ comprehension and participation in real-time communication. However, they often overlook providing direct speaki...

Understanding and Supporting Online Discussion with Opinionated Chatbots

Opinionated chatbots are increasingly present on online platforms and have the potential to shape public discourse by influencing individuals’ viewpoints before they engage in discussions. Despite their growing presence, the impact of interacting with opinionated chatbots on subs...

Effect of dolomite and kaolin on pollutant emissions and ash agglomeration during pressurized oxy-fuel co-firing of chicken manure and lignite

Against the background of carbon neutrality, chicken manure is a promising animal-derived biomass for cleaner energy recovery, but its high ash and alkali contents cause pollutant-control and agglomeration problems during fluidized-bed utilization. This study compared dolomite an...

Numerical Investigation of Sequence Modeling Theory using Controllable Memory Functions

The evolution of sequence modeling architectures, from recurrent neural networks and convolutional models to Transformers and structured state-space models, reflects ongoing efforts to address the diverse temporal dependencies inherent in sequential data. Despite this progress, s...

Deep-Subwavelength and Broadband Quarter-Wave Retardation in Ultrathin Hyperbolic MoOCl2

Abstract The miniaturization of polarization-controlling optical components is one of the central pursuits in nanophotonics. While traditional anisotropic materials require large propagation lengths to achieve the desired phase shifts, metasurfaces mitigate this size constraint b...

Leveraging AI for Direct Bystander Intervention Against Cyberbullying

Cyberbullying is a pervasive problem in online environments, causing substantial psychological harm to victims. Although bystander intervention has proven effective in mitigating its impact, motivating bystanders to engage in direct intervention remains a persistent challenge. St...

(De)composing Craft: An Elementary Grammar for Sharing Expertise in Craft Workflows

Craft practices rely on evolving archives of skill and knowledge developed through generations of craftspeople experimenting with designs, materials, and techniques. Better documentation of these practices enables the sharing of knowledge and expertise between sites and generatio...

Relaxation Piezoionic Hydrogel for Self-Powered, Self-Decoupled Monitoring of Finger Rehabilitation

Abstract Hand motor dysfunction involves limited finger flexion and impaired release control, making finger flexion angles and active relaxation ability key metrics for rehabilitation assessment. However, existing flexible electronics quantify deformation amplitude, while deforma...

Global policy determinants of national human papillomavirus vaccine introductions in 2006–2025

BACKGROUND: Although safe and effective human papillomavirus (HPV) vaccines have been available since 2006, national introduction in low- and middle-income countries (LMICs) has progressed slowly. HPV vaccine adoption may have been shaped by evolving World Health Organization (WH...

Reconfigurable Logic Operation of MoTe 2 Homojunction Enabled by Staggered Double‐Sided Contacts

ABSTRACT Reconfigurable transistors capable of dynamically switching between p‐ and n‐type operations are highly desirable for compact and energy‐efficient logic circuits. Here, we demonstrate a reconfigurable MoTe 2 transistor enabled by a staggered double‐sided contact (SDC) ar...

An Asymmetry Problem for Telic Perfectionism: A Reply to Kauppinen

Abstract The disvalue objection from pain is a key objection against perfectionistic views of well-being. In response, perfectionists have attempted to develop refined versions of perfectionism that circumvent the disvalue objection. One recent novel attempt is by Antti Kauppinen...

Exploring treatment burden and self-management experiences among adults receiving haemodialysis to inform person-centred digital care: a descriptive qualitative study

Person-centred care identifies the need to understand what matters to an individual, as opposed to what is the matter with them. Although digital technologies are increasingly used to support haemodialysis self-management, little is known about how the experiences of those receiv...

Transportability of Prognostic Markers

Transportability, the ability to maintain performance across populations, is a desirable property of markers of clinical outcomes. However, empirical findings indicate that markers often exhibit varying performances across populations. For prognostic markers that are advertised a...

Genome-wide analysis of social behaviour across social domains, reporters and developmental stages: a meta-regression approach

Abstract Social behaviour is a heritable trait linked to well-being and mental health, yet it varies across social context, including social domains, informants and development, which may shape its underlying genomic architecture. Here, we conducted a genome-wide meta-regression...

An Integrated Fabric‐Pneumatic Soft Sensing System for Multi‐Site Muscle Activity Decoding

Force myography (FMG) decodes movement intent from muscle deformation rather than bioelectrical signals, avoiding electrode–skin coupling issues that constrain surface electromyography. Most FMG implementations rely on rigid force‐sensitive resistors with limited conformability....

A Temporally Programmed Microneedles Platform for Long‐Acting Regulation and Rapid Sensing of Systemic Copper Dyshomeostasis

ABSTRACT Developing a minimally invasive platform capable of simultaneously enabling long‐acting copper metabolism regulation and rapid copper sensing remains a critical unmet challenge in addressing systemic copper dyshomeostasis. Here, we report a temporally programmed dual‐mod...

Clonal Hematopoiesis of Indeterminate Potential Proteomic Risk Score for Predicting Clinical Outcome in Patients With Heart Failure With Preserved Ejection Fraction

BACKGROUND: Clonal hematopoiesis of indeterminate potential (CHIP) is common in heart failure with preserved ejection fraction (HFpEF). However, the proteomic signatures linked to CHIP driver mutations and their prognostic implications in HFpEF remain poorly defined. We aimed to...

Elucidating the source and metabolic impact of 2‐phenylethanol on Lactiplantibacillus pentosus 1 using a fish broth fermentation model

Abstract BACKGROUND The quality of traditional fermented sour fish is shaped by metabolic interactions between core microbiota dominated by lactic acid bacteria (LAB) and yeasts. 2‐Phenylethanol (2‐PE) is a characteristic metabolite and quorum‐sensing molecule of Saccharomyces ce...

Mapping the methodological landscape of coupling carbon and electricity markets: A critical review of models, applications, and future pathways

Coupled carbon-electricity markets are increasingly important for power-sector decarbonization, but existing studies remain fragmented in their modeling objectives, assumptions, and methodological choices. To address this gap, this study develops a bibliometric-informed methodolo...
