Vane detachment in rotary compressors under low-speed conditions: Mechanisms based on mixed lubrication analysis

To ensure comfort and save energy, room air conditioners need to operate under low-temperature cooling and high-temperature heating conditions, under which the rotary compressor often runs at low rotational speeds (below approximately 20 Hz for cooling and 30 Hz for heating). Thi...

Coal/NH3 co-firing in a 50-kW self-sustaining combustor test rig: effects of dual-fuel mixing control and air staging

Ammonia–coal co-firing is a promising route for reducing greenhouse-gas emissions while utilizing existing coal infrastructure. However, simultaneously achieving high combustion efficiency, low NOx emissions, and limited unburnt NH 3 remains challenging because pollutant formatio...

Modulation of precession-forced Asian–African monsoon and arid climate variability by obliquity

Precession and obliquity play vital roles in orbital-scale climate change. However, their combined effects remain poorly understood. In this study, we examine how obliquity modulates precession-driven climate responses across Asian–African monsoon and arid regions (AAMAR). Result...

Lattice Boltzmann Modeling of Droplet Impact on a Superhydrophobic Ridge

ABSTRACT The impact dynamics of droplets on a single rectangular superhydrophobic ridge are systematically investigated using the lattice Boltzmann method. The effects of ridge width, droplet deviation, and Weber number on droplet deformation and breakup are examined through exte...

Luteolin potentiates antibiotic activity against multidrug-resistant Pseudomonas aeruginosa and modulates efflux-associated resistance and biofilm-associated phenotypes

Abstract Multidrug-resistant Pseudomonas aeruginosa is a WHO critical-priority pathogen whose recalcitrance is driven largely by efflux pump overexpression and biofilm formation, two mechanisms rarely addressed by a single agent. Here we evaluated whether luteolin, a plant-derive...

Coordinated planning of hydrogen refuelling stations and distribution networks considering two-phase hydrogen storage and carbon emission flow

Hydrogen refuelling stations (HRSs) are essential infrastructure for hydrogen-powered transportation. However, their planning faces coupled challenges arising from high-pressure hydrogen storage risks and the indirect carbon emissions caused by grid-connected electrolysis. To thi...

Association of dietary antioxidant patterns with heart failure risk in patients with hypertension

Hypertension is a major modifiable risk factor for heart failure (HF) and contributes substantially to the cardiovascular disease burden in China. Oxidative stress and redox imbalance have been implicated in the progression from hypertension to HF. The composite dietary antioxida...

A note on test elements for monomorphisms of free groups

A word in a group is called a test element if any endomorphism fixing it is necessarily an automorphism. In this note, we give a sufficient condition in geometry to construct test elements for monomorphisms of a free group, by using the Whitehead graph and the action of the free...

High-Efficiency Switching of the Topological Antiferromagnetic State in Mn3Sn via Magnon Torques

Abstract Noncollinear antiferromagnet Mn3Sn offers a large anomalous Hall effect, zero stray field, and terahertz dynamics for high-density ultrafast memory, but switching its topological magnetic state remains challenging. Here, we demonstrate that magnon torques originating fro...

Water-oil interfacial kinetics control enables water-based organic solar cells with 12.59% certified efficiency

Organic solar cells (OSCs) are promising for clean-energy generation, but sustainable production remains constrained by hazardous organic solvents. Aqueous organic-semiconductor nanoparticle (NP) inks offer an environmentally friendly route to OSCs, yet low efficiency and limited...

Integrated 3D fully kinetic simulation of field-reversed-configuration formation with embedded coils

We present an integrated, three-dimensional, fully kinetic particle-in-cell simulation of field-reversed-configuration (FRC) formation at the device scale. To our knowledge, this is the first fully kinetic model of whole-device FRC formation. The model embeds the drive coils dire...

RobustSCI: Beyond reconstruction to restoration for snapshot compressive imaging under real-world degradations

Deep learning has greatly advanced video Snapshot Compressive Imaging (SCI), but most existing methods are developed for reconstructing videos from relatively clean or idealized compressive measurements. In practical capture, motion, low illumination, and sensor imperfections can...

A two-stage restoration model for power distribution systems with integrated satellite-terrestrial communication networks

With the development of the satellite internet, the low Earth orbit (LEO)-based satellite communication network (SCN) is gradually applied to power grids to meet the emergency communication requirements. By the advantages of SCN, this paper proposes a two-stage restoration framew...

Air pollution and early-onset lung cancer: from environmental carcinogenesis to early intervention strategies.

Air pollution remains a global public health challenge, with nearly the global population (99%) breathing air that exceeds World Health Organization (WHO) guideline limits-annual means of 5 μg/m3 for PM2.5 and 15 μg/m3 for PM10. Both household and ambient air pollution are classi...

Asymmetric Co 2+ –Ov–Co 3+ Sites With Strong d–π* Interactions for Activating Nitrogen Toward Photocatalytic Ammonia Synthesis

ABSTRACT Solar‐driven photocatalytic nitrogen reduction reaction (p‐NRR) offers a sustainable pathway for ammonia synthesis under ambient conditions. However, its efficiency is fundamentally hampered by the kinetic inertness of the N≡N triple bond. Herein, we construct oxygen‐vac...

Experimental and numerical investigation of LBE flow and heat transfer in a grid-spaced hexagonal 7-rod bundle with cosine axial power distribution

To support thermal-hydraulic design and safety assessment of lead-cooled fast reactor fuel assemblies, this study investigates the flow and heat transfer characteristics of lead-bismuth eutectic (LBE) in a grid-spaced hexagonal 7-rod bundle under a cosine axial power distribution...

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...

Spatial variability and drivers of N2O emission responses to nitrogen fertilization across agricultural regions in China

Nitrogen fertilization is an important source of agricultural N 2 O emissions, yet the spatial variability in nitrogen-induced N 2 O responses and its underlying drivers across agricultural regions in China remain insufficiently understood. This study conducted a meta-analysis of...

Accelerating Regular Expression Matching over Compressed Data via Decoupled Speculative Execution on FPGA

The common practice of compressing network traffic to enhance transmission efficiency poses a significant challenge to achieving high-speed regular expression matching. Since matching compression data relies on prior decompressed data and earlier matching outcomes, the convention...

A comprehensive review of an artificial intelligence-based framework for classifying and solving modified heat partial differential equations

Partial differential equations (PDEs) fundamentally describe the dynamic relationships among physical quantities and therefore play an essential role in modelling physical processes such as heat transfer, fluid flow, population dynamics, and material behavior, unlike purely algeb...
