Hardware‐Efficient FMCW Laser Ranging Beyond the Coherence Length Approaching the Wiener Phase Noise Limit

ABSTRACT Coherent ranging based on frequency‐modulated continuous‐wave (FMCW) lasers is highly promising for autonomous systems. However, the high‐cost laser source hinders the large‐scale deployment of FMCW lidar, which requires both narrow linewidth and large tuning bandwidth....

Depressive, Anxiety, and Stress Symptoms Among Respiratory Therapists in Two Tertiary Hospitals in Saudi Arabia: Differences According to Sociodemographic Characteristics

Background: Respiratory Therapists (RTs) work in high-stress environments, predisposing them to psychological distress. This study evaluated the proportion of depressive, anxiety, and stress symptoms and their differences across sociodemographic groups among RTs in two Saudi Arab...

Risk factors of anterior capsular contraction syndrome in Marfan syndrome after intraocular lens and modified capsular tension ring implantation

Purpose To identify risk factors for anterior capsular contraction syndrome (ACCS) after in-the-bag intraocular lens (IOL) implantation in patients with Marfan syndrome (MFS) and ectopia lentis (EL). Methods This study included patients diagnosed with MFS and EL, who underwent in...

Perfect precise colourings of uniform tilings with regular star polygons

This paper deals with the problem of colouring n-valent uniform tilings with regular star polygons using n distinct colours, such that one tile of each colour occurs at each vertex (precise colouring), and such that every element of the symmetry group of the tiling induces a perm...

Timing of Vasopressin Initiation in Sepsis Patients on Norepinephrine: A Target Trial Emulation

Background The optimal timing for initiating vasopressin in septic shock remains uncertain, with conflicting evidence potentially arising from variations in patient severity and methodological limitations such as immortal time bias. This study aimed to evaluate the time-varying e...

Compatibility of Low‐Dimensional Perovskites in n–i–p and p–i–n Perovskite Solar Cells

ABSTRACT Low‐dimensional (LD) perovskites have emerged as a cornerstone strategy for mitigating the intrinsic instability and suppressing interfacial non‐radiative recombination in 3D perovskites. Nevertheless, the intrinsic charge transport anisotropy of LD phases fundamentally...

Astrocytic activity in treatment-resistant and ultra-treatment-resistant schizophrenia

Astrocytic dysfunction has been implicated in schizophrenia, but biomarkers of astrocytic activity have shown inconsistent patterns. Studies on disease heterogeneity, specifically treatment-resistant schizophrenia (TRS) and ultra-treatment-resistant schizophrenia (UTRS) are lacki...

Light‐Assisted Sub‐Coercive Ferroelectric Programming for Reconfigurable In‐Sensor Logic

ABSTRACT Reconfigurable optoelectronic logic devices are attractive for in‐sensor computing, yet their practical deployment is often hindered either by structurally complex heterostructures or by the limited reconfigurability of simple single‐material platforms. Here, we report l...

Impact of excessive weight gain and pre-gestational obesity on maternal and neonatal outcomes

Excessive gestational weight gain and prepregnancy obesity have been associated with adverse maternal and neonatal outcomes, although their associations with specific pregnancy outcomes may differ. This retrospective, cross-sectional study included 972 women who delivered at a pu...

Evaluating the Antimicrobial Activity of Curcumin-loaded Lipid Nanocarriers When Applying Photodynamic and Sonodynamic Therapy for the Treatment of Skin Infections

Abstract Purpose The antimicrobial activity of curcumin is the focus of this article, which sought to enhance it by formulating curcumin in lipid nanocarriers, and by applying Sonodynamic Therapy (ST) and Photodynamic Therapy (PT). Methodology Curcumin-loaded lipid nanocarriers w...

Surrogate Decision-Making for Older Adults With and Without Dementia

Importance End-of-life care for older individuals in the US frequently includes interventions that may be burdensome and inconsistent with patient preferences. Few experimental studies have assessed potentially modifiable factors associated with surrogate recommendations. Objecti...

Health literacy and combined adherence to aerobic and muscle-strengthening physical activity guidelines among Korean adults: findings from the 2023 Korea National Health and Nutrition Examination Survey

Regular physical activity is essential for preventing noncommunicable diseases; however, combined adherence to aerobic and muscle-strengthening physical activity guidelines remains low. Although health literacy may influence individuals’ ability to understand and implement recomm...

Distributed Phase-Shedding: A Scalable Solution for Automotive Microprocessor Power Supplies

The increasing computing power required by autonomous vehicles imposes stringent requirements on automotive microprocessor power supplies in terms of efficiency, scalability, and fault tolerance. Conventional phase-shedding strategies for multiphase converters rely on centralized...

Acid–Base-Mediated Self-Assembly: Synthetic Access to High-Energy-Density Metal–Organic Frameworks and Host–Guest Energetic Materials

Abstract Controlled condensed-state chemical reactions are critical for smart-material development. Reaction-driven self-assembly materials have been explored for decades across organic nanostructure, polymer, and biomaterial research. This strategy has recently enabled the desig...

Hydraulic assessment and capacity enhancement of a pump-fed canal within New Delta project: a case study of El Nasr Canal, Egypt

The New Delta is an ambitious project aimed at transforming desert areas into agricultural land and supporting Egypt’s food security. Water scarcity is a major challenge, requiring the use of groundwater, treated drainage water, and Nile water. El Nasr Canal, operated by five pum...

The Defensorium unitatis christianae (1450) and the ethical-rational royal absolutism

Firstly, this article aims to highlight the links between Alfonso de Cartagena’s Defensorium unitatis christianae and Pablo de Santa María’s Scrutinium Scripturarum, with a view, on the one hand, to shedding light on the Thomist tradition that underpins both treatises, and, on th...

AI research in libraries (2017–2025): a scoping review with bibliometric mapping across the COVID era

Purpose This study examines how research on artificial intelligence (AI) in libraries evolved between 2017 and 2025, with specific attention to changes before, during and after the COVID-19 period. It seeks to identify shifts in publication trends, geographic participation, thema...

An international multicenter analysis of the outcome of pediatric first variceal hemorrhage

Background & Aims: Management of portal hypertension in children including primary prophylaxis of variceal bleeding is controversial due to limited understanding of mortality risk after first variceal hemorrhage (1VH). This international multicenter study was designed to advance...

Screening Tunnel Configurations for Reduced Micro-UAV Hover Performance Using Marker-Based Visual Measurements

Micro-unmanned aerial vehicles (micro-UAVs) used for tunnel inspection must hover near structural boundaries that can affect the combined vehicle–environment response. This paper presents an outcome-based physical method for screening tunnel configurations through marker-linked f...

Targeted Philanthropy: Evidence from M&As

ABSTRACT I show how firms optimize the allocation of charitable funds around investments that require external stakeholder support, such as mergers and acquisitions. Acquirers increase donations to target‐related charities before making a takeover offer, but scale funds back afte...
