Ethical regulation of human research in educational institutions for health professions: A cross-national study

Introduction: International research collaboration is increasingly valued. However, the diversity of ethical regulations for human research across health professions education institutions (HPEI) presents growing challenges. While international frameworks provide an ethical found...

First-principles electronic transport properties of Ti and Ti-6Al-4V for modeling ultrashort-pulse laser ablation

Predictive modeling of ultrashort-pulse laser ablation requires temperature-dependent material parameters derived from the electronic structure, namely the electronic thermal conductivity, electron-phonon coupling, and heat capacity. These parameters are well documented for eleme...

Adding Carnot battery functionality to combined-cycle gas turbine power and cogeneration plants

This study assesses how combined-cycle gas turbine (CCGT) plants, especially in combined heat and power (CHP) operation, can be retrofitted as Carnot batteries by integrating high temperature power-to-heat (P2H) unit and thermal energy storage (TES) between the gas turbine (GT) a...

Optimal Depolarization Sequence for CRT Patients

Abstract Background Electrical ventricular dyssynchrony is a hallmark of intraventricular conduction disease in heart failure with reduced ejection fraction. Although cardiac resynchronization therapy (CRT) is effective, a proportion of patients with ECG evidenced electrical dyss...

Observation of relativistic bond weakening in seaborgium hexacarbonyl

Abstract The seventh row of the periodic table of the elements has been completed with the discovery of the five heaviest elements from flerovium (Fl, Z = 114) through oganesson (Og, Z = 118) 1 . Chemical properties of the superheavy elements (SHE, Z ≥ 104) are unique owing to th...

Deep phenotyping of white matter tissue composition in dementia with Lewy bodies

Abstract Background White matter signal abnormalities (WMSA) on MRI are common in dementia with Lewy bodies (DLB), and more severe WMSA have been associated with increased neurodegeneration in DLB. However, the underlying mechanisms of WMSA remain unclear. Single-Shell 3-Tissue C...

Effect of localized damage on lateral–torsional buckling capacity of continuous steel I-beams

This paper investigates the Lateral-Torsional Buckling (LTB) resistance of continuous hot-rolled steel I-beams with localized cross-sectional damage. Due to the alternating sagging and hogging moment regions, continuous beams exhibit spatially varying compression flanges and buck...

Probing dark matter interactions with a RES–NOVA prototype cryogenic detector

Abstract We report on the operation of a 13 g PbWO $$_4$$ 4 crystal, grown from archaeological Pb and operated as a cryogenic calorimeter in an underground environment. Read out with a Ge thermistor, the detector achieves a low energy threshold and, for the first time, enables th...

Two-year smartphone motor monitoring in isolated REM sleep behavior disorder and Parkinson’s disease

Abstract We aimed to assess the sensitivity of key motor smartphone tasks to detect disease progression in subjects with isolated rapid eye movement sleep behavior disorder (iRBD) and early Parkinson’s disease (PD) compared to healthy controls. Twenty-six healthy controls, 22 pat...

Measurements of the production of W$$^{\pm }$$ and Z$$^0$$ bosons in pp collisions at $$\sqrt{s} = 13$$ TeV

Abstract Measurements of the production of the W $$^{\pm }$$ ± and Z $$^0$$ 0 bosons at midrapidity in pp collisions at $$\sqrt{s} = 13$$ s = 13 TeV with ALICE at the Large Hadron Collider (LHC) are presented. The W $$^{\pm }$$ ± and Z $$^0$$ 0 bosons are detected via their (di)e...

Solving Stengle’s Example in Rational Arithmetic: Exact Values of the Moment-SOS Relaxations

We revisit Stengle’s classical univariate polynomial optimization example min 1 - x 2 s.t. ( 1 - x 2 ) 3 ≥ 0 whose constraint description is degenerate at the minimizers. We prove that the moment-SOS hierarchy of relaxation order r ≥ 3 has the exact value - 1 / ( r ( r - 2 ) ) ....

Debris cloud redirection in origami-inspired foldcore structures under hypervelocity impact: a review

The increasing population of micrometeoroids and orbital debris (MMOD) has intensified the need for lightweight and efficient shielding systems capable of withstanding hypervelocity impacts (HVI). Conventional shielding concepts, such as Whipple shields and honeycomb or foam-core...

Analysis of mixed radiation fields at the MoEDAL experiment based on real-time data from a Timepix detector network

Abstract The primary objective of this work is the determination of fluences and characteristics of fast neutrons, other hadrons, and highly ionizing particles (HIPs) in the environment of the MoEDAL experiment at the Large Hadron Collider. These particles may constitute an exper...

Privacy-Preserving Detection of Post-Fall Lying Posture Using a Low-Resolution Infrared Sensor and an Edge FOMO Neural Network

Falls in older adults are a leading cause of injury, and the time spent on the floor afterwards is the stronger predictor of outcome. We present a low-cost system that detects the sustained lying posture following a fall. An FLIR Lepton 3.1R (160 × 120 px) and an int8-quantized F...

Hysteresis in the Czech Housing Market: Price Dynamics over the First Complete Mortgage Interest Rate Cycle, 2018–2026

The period 2018–2026 offers the first opportunity to observe a complete, closed mortgage interest rate cycle in the Czech Republic: rates fell to a historic trough of 1.98% (March 2021), rose to 5.37% (September 2023) and stabilized around 4.5% from 2025. This paper examines whet...

Object Aligner paper experiments: code and aggregated results

Object Aligner (OA) is a Python library that scores two JSON objects by recursively aligning their trees: the Hungarian algorithm for unordered collections, sequence alignment for ordered ones, and partial credit at the granularity the schema declares. It is configured entirely t...

Calcined Clays for Low-Carbon Construction: Effects of Production Technology on Carbon Footprint

Calcined clays are increasingly recognized as strategic supplementary cementitious materials for reducing clinker consumption and the environmental impacts of construction. However, life cycle assessments typically represent metakaolin production using a single carbon footprint v...

Superconductivity in epitaxial PtSb(0001) thin films

Building on earlier reports of superconductivity in bulk PtSb, we present a systematic study of superconductivity in epitaxial PtSb(0001) thin films grown on SrF 2 ( 111 ) . Electrical transport measurements reveal a superconducting transition at T c = 1.72 K . The field-induced...

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...
