(Short Paper17) The Physical Inevitability of Sleep in the Biolog ical QPU Paradigm: Phase Noise Rejection and Autonomous Calibration of Absolute Coordinates

Sleep is a universal phenomenon observed across all life, yet conventional biochemical interpretations (e.g., removal of fatigue substances and maintenance of synaptic homeostasis) struggle to physically explain the fatal breakdown of spatial cognition (loss of depth perception a...

Reconstructing and Extending Ramanujan's 1914 Series for 1/π: A Line-by-Line Proof of the Modular Equation Theory, With Five New Quartic-Theory Series

This paper has two parts. First, we give a complete, self-contained reconstruction of the proof of Equation 3 in Ramanujan's 1914 paper "Modular equations and approximations to π" [Ramanujan 1914], starting from the elementary problem of the perimeter of an ellipse and building u...

Congenital aphantasia: what we (think we) know, what we thought we knew but were mistaken about, and what we don't know

Congenital Aphantasia initially described a lifelong inability to visualise. But it is now understood to manifest as imaginative inabilities that can encompass multiple sensory modalities (e.g. vision, audio, movement, taste, touch, smell). Congenital Aphantasia has become a focu...

Treat paediatric asthma with a personalised and stepwise approach

Asthma is a chronic respiratory disease that causes recurrent symptoms such as wheeze, shortness of breath and cough. It is characterised by airway inflammation and hyperresponsiveness and variable expiratory airflow. Pharmacological management of paediatric asthma involves a ste...

A beam-down linear Fresnel reflector integrated with photovoltaics for combined heat and electricity production

A beam-down linear Fresnel reflector coupled with a flat plate receiver and photovoltaics is designed and investigated in optical and thermal terms. The secondary reflector has a triangular shape both for increased efficiency and potentially reduced construction cost, which is a...

Non-Coalesced ZIF-8 MOF-Derived Hierarchical Porous Carbon Nanofibers for Energy Storage Applications

Abstract The development of a nitrogen-doped carbon nanofiber-incorporated 3D MOF structure as an electrode for an energy storage device has attracted significant attention for advanced electrochemical performance due to its high energy and power density. Herein, ZIF-8 was delibe...

Remote parent coaching in preschool mathematics: Evidence from Peru

We evaluate a 10-week intervention in Peru that randomly offered remote coaching to parents of preschool children during the 2021 summer break, complementing publicly available mathematics lessons delivered by broadcast media. Coaches provided guidance and encouragement through p...

Spatiotemporal evolution and nonlinear drivers of land surface temperature in the Guangdong–Hong Kong–Macao Greater Bay Area from 2000 to 2020

Against the dual pressures of global warming and rapid urbanization, understanding the evolution and driving mechanisms of urban thermal environments is essential for sustainable urban development. Using multi-source remote sensing, land-use, landscape pattern, and socioeconomic...

Next frontier of Earth observation: Quantum-enhanced multispectral remote sensing for ultra-low signal environments

Optical Earth observation is approaching a fundamental physical limit imposed by photon scarcity, rendering many critical environments, such as polar night regions, dense forest canopies, and optically deep ocean layers, effectively unobservable by classical radiometric sensors....

Single-cell multi-omics landscape of mouse embryogenesis

we present a paired single-cell dual-omics atlas of mouse embryogenesis using HT-scCAT-seq, capturing joint transcriptome and chromatin-accessibility profiles across five stages (E8.5-E12.5), this cell-type-resolved resource establishes a quantitative framework for understanding...

Smart Implant Coating with Pathological-Microenvironment-Driven Drug and Nanozyme Delivery for Osteoporotic Bone Healing

Stimuli-responsive drug delivery from orthopedic implants holds particular promise for enhancing osseointegration in osteoporotic bone. However, challenges such as the lack of feedback-regulated functionality and microenvironmental modulation persist. Here, we developed an osteop...

Unraveling the Hydration Behavior of Poly(2-Methoxyethyl Acrylate) and Its Model Monomer via Molecular Dynamics Simulations

Abstract The hydration behavior of polymeric materials is governed by a subtle interplay between local chemical functionality and polymer backbone connectivity. In this work, we investigate the hydration behavior of poly(2-methoxyethyl acrylate) (PMEA) and its monomeric analogue,...

Heavy metal concentrations in composite breast milk and health risk assessment for breastfed infants in Ho, Ghana

Background Breast milk is the optimal source of infant nutrition but may serve as a pathway for exposure to environmental contaminants. Objectives To quantify aluminum (Al), arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg) in composite breast milk and assess non-carcinogen...

Engineering the Enzyme−Support Interface: Arginine-Directed Anchoring of Peroxygenase on a β-Ketoester Covalent Organic Framework

Controlling the conformation and orientation of enzymes at solid interfaces is a central challenge in the design of functional biohybrid materials, and the outcome depends sensitively on the chemistry and geometry of the enzyme-support interface. Here, a β-ketoester-functionalize...

Informal teacher leadership and teacher occupational well-being in Chinese higher education: The role of sense of power

This study examined the relationships among informal teacher leadership, sense of power, and teacher occupational well-being among university teachers in eastern coastal China. Survey data from 404 full-time university teachers across ten universities were analysed using structur...

Improving visibility of discontinuities on seismic data with colour processing technique – resolution concept across scales

The purpose of this paper is to show the application of the colour-processing technique to enhance the visibility of fractures and faults for more detailed structural interpretation. Colour-processing is a post-migration, post-processing technique that can be applied in an interp...

Ionic-Environment Control of Highest Occupied Molecular Orbital−Lowest Unoccupied Molecular Orbital Levels and Polaronic Transitions in Sulfonated Polyaniline Nanobelts: A Platform for Switchable Conductivity and Antibacterial Activity

Abstract The frontier molecular orbital energies and polaronic transitions of conjugated polymers are exquisitely sensitive to their ionic environment, yet this relationship has remained underexplored in sulfonated polyaniline systems. Herein, an environmentally friendly, templat...

Diagnosis of urinary tract infection in the emergency department – a real infection or an alarming indication for comprehensive geriatric assessment? A retrospective follow-up study
