Optotagging in primate cortex uncovers excitatory and inhibitory neuron specializations in form vision

Abstract The perception of complex visual shapes is a hallmark of primates and a foundation for many of their decisions and actions. The neural mechanisms of this visual function are best studied in macaques, but progress in this animal model has been hampered by the inability to...

3D-Printed Geopolymer Composite Truss Beam: Experimental Verification of Manufacturing and Load-Bearing Capacity in Four-Point Bending

Geopolymers represent a promising material platform for extrusion-based 3D printing; however, current research remains largely focused on mix design, rheology, printability, buildability, and the relationship between process parameters and the resulting microstructure. This artic...

Robot in a crib: How a playing robot helps us understand sensorimotor contingency learning

Learning sensorimotor contingencies—that is, the link between one’s actions and their sensory effects—is fundamental to developing body knowledge, understanding causality, and developing a sense of agency. In developmental psychology, this process is classically studied using the...

Alpha Without Access: Execution Constraints in a Bonding-Curve Market

We report a market in which a positive return is visible in prices yet cannot be realized by a fixed trading policy, and we measure why. On a frozen set of 1,220 tokens approaching the pump.fun graduation boundary, a counterfactual buy that ignores the execution race shows a medi...

Coupling of Pacific and Indian Ocean variability disrupted by 19th century volcanism

The stability of inter-basin coupling between the tropical Pacific and Indian Ocean remains uncertain. This study shows that past volcanism can temporarily weaken this relationship, but recent decoupling due to global warming is unprecedented.

User-Behaviour-Based Dynamic Clustering Optimisation Algorithm for True Demand Prediction of Shared Bikes

Dockless bike-sharing systems are increasingly important for sustainable urban mobility, yet they frequently suffer from spatial misallocation between supply and demand. Conventional demand forecasting relies primarily on historical trip records and therefore systematically under...

An intermediate scale R-axion & the QCD axion

A bstract An intermediate scale R-axion faces an immediate obstruction from the Dine-Festuccia-Komargodski (DFK) bound on the superpotential, 2|⟨ W ⟩| ≤ f R F , since for a nearly Minkowski vacuum it typically follows that f R ≳ M Pl . We show that this lower bound on f R can be...

Global research landscape of natural medicines for lower urinary tract symptoms: bibliometric and clinical trial analysis

Abstract Background Natural medicines have demonstrated significant therapeutic potential in the management and attenuation of lower urinary tract symptoms (LUTS). According to the Web of Science Core Collection (WoSCC), a total of 497 related articles have been published during...

Grating-Lens Metafiber with Enhanced Angular Acceptance for Broadband Light Coupling

This is the data set of publication: Grating-Lens Metafiber with Enhanced Angular Acceptance for Broadband Light Coupling

Machine Learning-Based First-Trimester Antenatal Risk Prediction for Adverse Maternal and Neonatal Outcomes: Multicenter Model Development Study.

Background: Maternal outcomes remain inequitable worldwide. Severe morbidity persists, and current risk assessment tools are largely arbitrary, focusing on biomedical factors while overlooking social determinants of health. There is a need for data-driven AI models to improve ear...

Factors associated with psychological distress and academic performance among medical students in Palestine: a convergent mixed-methods study

Abstract Background Medical education is associated with substantial psychological stress, and students in Palestine may experience additional strain related to political instability, mobility restrictions, and financial uncertainty. This study assessed psychological distress and...

A Systematic Review of Relationships Between Self-Directed Speech and Self-Processes

Self-directed speech is a well-established aspect of human cognition, although its relationships with self-processes such as self-consciousness, self-rumination, mindfulness, self-concept clarity, and self-esteem remain poorly understood. The present study aimed to synthesize exi...

Applications of artificial intelligence in the analysis of alveolar clefts: a scoping review

Background Alveolar clefts are a prevalent clinical manifestation of cleft lip and palate (CLP), and are typically managed with secondary alveolar bone grafting (SABG) during mixed dentition. Nonetheless, considerable variability in the morphology and volume of the defect influen...

Couple Decumulation under Stochastic Survivorship Transition Timing

Addendum 2 to DAGM — rolling history and a Phase-A timing grid.

A scoping review of virtual reality technology utilization in patients with colorectal cancer

Virtual reality (VR) technology has shown promise in supporting colorectal cancer (CRC) patients throughout their care journey; however, the evidence concerning its specific applications, intervention characteristics, and clinical outcomes remains scattered. This scoping review a...

Managing the Difficult Airway in Adults with Life-Threatening Cervical Infections: A Scoping Review

Background: Airway management in patients with cervical infections remains a major challenge because progressive swelling and distortion of the upper airway may rapidly lead to life-threatening airway obstruction. Despite advances in imaging and advanced intubation techniques, th...

Direct experimental test of Feynman’s path integral postulates with single photons

The experimental validation of fundamental thought experiments in quantum mechanics has profoundly advanced quantum science and technology while deepening our understanding of quantum mechanics. However, experimental studies of the path integral formulation, a cornerstone of quan...

Molecular identification of Hypoderma sinense cutaneous myiasis in a child from a cattle-raising pastoral region of China: a case report

Abstract Background Zoonotic parasitic infestations may be overlooked when they mimic common pediatric skin infections. Cutaneous myiasis caused by Hypoderma species is mainly associated with livestock, whereas human infestation by Hypoderma sinense ( H. sinense ) is rarely repor...

Directional Pheromone Gradient Observations for Decentralized Multi-Agent Reinforcement Learning in Swarm Drone Search and Rescue

Search and rescue (SAR) for disaster response involves quick and efficient exploration of large, uncertain, and dangerous spaces. In this paper, we introduce a swarm-drone SAR approach with a key innovation in the form of directional pheromone gradient observation, where each age...
