Epiploic–mesenteric knotting as a rare cause of small-bowel obstruction

Abstract Background Epiploic–mesenteric knotting is an exceptionally rare cause of acute small-bowel obstruction. The condition results from entanglement between the greater omentum and the small-bowel mesentery, creating a true knot that may rapidly progress to strangulation and...

Covalently Linked Peptides and Membrane Potential Enable CyaA Segment Translocation

The adenylate cyclase toxin (CyaA) from Bordetella pertussis intoxicates host cells by directly translocating its N-terminal catalytic domain across the plasma membrane; however, the forces driving this unique process remain poorly defined. Here, we dissect the membrane transloca...

Thermal error prediction for gantry guideway grinder spindle based on CNN-BiLSTM-Attention

Abstract Aiming at the strong nonlinearity, time-series lag, and multi-physics coupling characteristics of spindle thermal error in gantry guideway grinders, as well as the insufficient feature extraction and poor generalization ability of single deep learning models under varyin...

Heat‐to‐Electricity Conversion Using Barium Strontium Titanate Multilayer Capacitors

ABSTRACT Pyroelectric materials are attractive for converting heat into electricity, yet the best performance is obtained with lead‐containing ceramics, remaining a major environmental concern. Here, we address this problem by developing lead‐free barium strontium titanate multil...

A folding and deployment strategy for infinite planes based on multi-hub chiral origami

Folding an infinite plane based on origami principles poses a fundamental challenge, particularly in aerospace engineering, where efficient stowage and deployment of large-scale structures such as membranes and solar arrays are critical. The flasher pattern is widely used to achi...

A Unified Framework for Calibration, Decoding, and Resource-Aware Processing in Hybrid Quantum-Classical Machine Learning

NISQ devices are bottlenecked by three coupled problems: drifting qubit frequencies, slow classical syndrome decoding (MWPM), and shot-noise in gradients. QCOP is the first closed-loop system that solves all three together inside a single GPU-accelerated pipeline: Spectral Calibr...

The role of solid solutions and intermetallic precipitates in the Al-Ni system under shock loading: a molecular dynamics study

Abstract Understanding the relationship between structure and shock response in metallic systems is essential for developing reliable materials in extreme environments. Here, molecular dynamics (MD) simulations are utilized to investigate the shock behavior of Al-Ni solid solutio...

Teaching AI governance in management education: A serious game for accountable decision-making under uncertainty

Management education increasingly needs ways to prepare students for AI governance, yet students have limited opportunities to practise the organisational judgement involved in deployment decisions. This paper presents “Leading in the Age of AI”, a card-based serious game in whic...

The effect of efficiency and self-discharge parameterization on the sizing of hybrid energy storage systems

Abstract A hybrid energy storage system (HESS) is a widely investigated setup as a means to reduce losses and system dimensions by combining storage technologies with complementary characteristics. However, reported benefits are often based on case studies and do not clearly dist...

Enhanced cell wall digestibility and immunity in Arabidopsis through targeted modification of xylan structure by heterologous expression of acetyl xylan esterase and xylanases

Abstract Background Xylan, a major component of the secondary cell wall in dicots, is often recalcitrant due to its acetylation and interaction with cellulose and lignin. To fine-tune the xylan structure and improve the processing of lignocellulosic biomass, overexpression of cel...

On track but too slow? The dynamics of EU decarbonization

Despite the strong commitment of European countries to achieve net-zero emissions by 2050, the extent to which key policies and drivers jointly shape emissions dynamics remains insufficiently investigated. The study suggests that the interaction among circular economy, energy tra...

Determinants of scaled implementation for electronic laboratory information systems in 27 clinical laboratories in Côte d’Ivoire: a mixed-methods study applying the Consolidated Framework for Implementation Research (CFIR)

Abstract Background Electronic laboratory information systems (LIS) are critical for promoting data quality and improving laboratory performance, but sustained implementation following system deployment in resource-limited settings can be challenging. The OpenELIS project in Côte...

On additive averaging kernels for finite Markov chains

Abstract We study additive mixtures of Markov kernels of the form $$A_\alpha = \alpha P + (1-\alpha )G$$ A α = α P + ( 1 - α ) G , where $$\alpha \in [0,1]$$ α ∈ [ 0 , 1 ] , P is a baseline sampler and G is a Gibbs kernel induced by a partition of the state space. We first motiva...

Charges of supergravity

A bstract We study conserved charges of $$ \mathcal{N} $$ N = 1 supergravity formulated as a constrained BF theory based on the OSp(1|4) superalgebra. Using the covariant phase space formalism, we derive bulk and boundary contributions to the symplectic structure and construct ch...

A multi-dimensional hybrid stochastic model for early and interpretable blockage detection in programming education

Abstract Detecting student difficulties in programming education is a critical challenge for instructors, a task further complicated by the rise of AI coding assistants that can obscure the learning process. While fine-grained interaction logs from development environments offer...

Importance of subpixel Earth surface reflectance and altitude for atmospheric trace gas retrievals from passive satellite instruments

Abstract. Satellite retrievals of atmospheric greenhouse gas columns are used to obtain information about greenhouse gas sources and sinks by inverse modeling. Such an application requires high accuracy, as even small biases of the retrieved concentrations may result in large err...

Adaptive Decision-Making in Audio Classification: A Systematic Review of Reinforcement Learning and Multi-Armed Bandit Frameworks

Adaptive decision-making has emerged as an important direction in audio classification. Reinforcement learning (RL) and multi-armed bandit (MAB) methods offer principled frameworks for sequential and localized decision-making. However, despite growing interest in these approaches...

Behavioural Friction Theory: Toward a Common Currency for Behavioural Science

Behavioural science has produced robust findings across dozens of research traditions, yet lacks the integrative architecture needed to connect them — a common unit or map for relating constructs across domains and anticipating cross-field interactions. Behavioural Friction Theor...

Hemp-derived cannabinoid use among young adults in Lexington, Kentucky in 2024

Abstract Introduction : The availability and use of hemp-derived cannabinoids (HDCs), such as delta-8-THC and CBD, have increased rapidly due to changes in US cannabis policy and their federally legal status. The health effects of HDCs remain largely unknown. Limited data exists...

Do coups create economic crises? Evidence from Latin America and the Caribbean

While most of the literature considers economic crisis as a precursor to coup attempts, theoretical considerations suggest that coups may also cause crises. Estimating effects of different types of coups on crisis risk across 32 countries in Latin America and the Caribbean betwee...
