Remote Calibratinga National-Wide Dense Low-CostSensor Network for Hyperlocal Air Surveillance

Abstract Emerging low-cost sensor (LCS) technologies offer a unique opportunity to achieve equitable, high-granularity air surveillance. Yet without proper calibration, their raw observations are often considered invalid for rigorous research and regulatory purposes. Common calib...

Explicit and high-precision period approximations for the circular Sitnikov restricted four-body problem

Abstract This brief note presents an explicit analytical approximation to the period of the circular Sitnikov restricted four-body problem. The proposed approximation achieves superior accuracy and greater algebraic compactness compared to existing analytical approximations acros...

SiCl4-Assisted Calcination Strategy for Lithium Recovery and Regeneration of Cathodes

Abstract The rapid growth of lithium-ion battery (LIB) deployment has intensified the need for efficient and sustainable recycling of spent cathodes. This work introduces a silicon tetrachloride (SiCl4)-assisted calcination strategy that repurposes SiCl4, a hazardous byproduct of...

Preparation Method of Simulated Deep Sandstone Materials Based on Dual Equivalence of Principal Components and Mechanical Properties, and Quantitative Evaluation of Simulation Effectiveness

Intact deep sandstone cores are scarce, heterogeneous with poorly repeatable, limiting systematic laboratory studies of deep-rock mechanical behavior. This study selected dense sandstone recovered from 1050 m in the Pingdingshan mining area as the prototype system for the develop...

Toward smarter solar: IoT and fuzzy logic for real-time maximum power point tracking and monitoring of photovoltaic systems

Abstract Photovoltaic (PV) systems are extremely prone to wear and tear and physical damage due to large variation in environmental conditions. Integration of real-time monitoring systems with PV would be highly advantageous in detecting early faults and performance degradation c...

p38β-mediated BiP phosphorylation drives stemness and chemoresistance by suppressing UPR activation in hepatocellular carcinoma

Abstract Tumor-initiating cells (TICs) promote tumor initiation and therapy resistance, yet the kinase regulators that sustain TICs remain incompletely defined. Here, we identify the stress kinase p38β (MAPK11) supports TIC maintenance and drug resistance in hepatocellular carcin...

Optimisation design of rail profiles for improving wear and RCF performances on a small-radius curve: A case study

Abstract Wear and rolling contact fatigue (RCF) are regarded as two prominent factors that deteriorate the long-term service performances and aggravate the maintenance costs of metro rails on the small-radius curves, therefore an effective countermeasure against which is needed....

Ergonomics-Aware Task Allocation for Human-Centric Collaborative Assembly: A Systematic Review

Human-centric manufacturing is reshaping collaborative production systems by repositioning human capabilities, safety, experience, and well-being as central concerns in the design and operation of intelligent manufacturing. As manufacturing moves toward Industry 5.0, task allocat...

A Technology-Blended Exercise Intervention for Cognitive Risk Reduction and Brain Health in Middle-Aged and Older Adults with Type 2 Diabetes in Singapore

BACKGROUND: Type 2 diabetes mellitus (T2DM) is a major modifiable risk factor for accelerated brain ageing, cognitive decline, and dementia. However, sustainable lifestyle interventions targeting cognitive health in at-risk older adult populations remain limited. This mixed-metho...

Leveraging Deep Reinforcement Learning to Facilitate the Transition from Knowledge Diversity to Knowledge Creation in Construction Project Teams

Abstract Knowledge diversity is essential for innovation in construction project teams, yet translating it into tangible outcomes remains challenging. Traditional management theories and static methods often fail to provide dynamic solutions. This study addresses the issue throug...

Predictive Effect of Neighborhood Disadvantage on Depressive Symptoms Among Chinese Middle-Aged and Older Adults: Social Support and Children’s Marital Status as Intervening Factors

Abstract Depressive symptoms among Chinese middle-aged and older adults have risen substantially in recent years, yet how neighborhood and family factors relate to mental health remains insufficiently understood in China. Using survey data from 1,177 respondents in Chengdu, this...

Elevating excellence: Examining the effects of spatial competition on hotel quality

This study investigates how spatial competition influences the quality of hotel properties in the lodging market. We collected hotel characteristics and online rating data for 3,443 properties in Texas, USA, spanning from 2010 to 2019. A two-way fixed-effects panel data model ind...
