Formalized threshold reversible hiding in encrypted images in Post-Quantum settings

Abstract As advancements in computer vision emerge, the necessity for securing image processing techniques also arises. For this purpose, one of the promising methods is Reversible Data Hiding in Encrypted Images (RDHEI), which directly secures visual data while providing the opt...

Spatially resolving isomeric trisaccharides on surfaces with Orbitrap-SIMS

Abstract Many biologically important molecules are structural isomers that share the same molecular mass yet differ in shape, bonding and function. This creates an ambiguity for mass spectrometry imaging (MSI), where chemically distinct species can be indistinguishable on the mas...

When do hedonic appeals backfire? Credibility, scepticism and the disconnect between emotional engagement and pro-environmental intention

This study examines why emotional engagement with hedonic sustainability communication does not always translate into pro-environmental behavioural intention. Drawing on the Persuasion Knowledge Model and Truth-Default Theory, it investigates consumer responses to pleasure- and c...

It’s not who you know: sociometric position did not shape children’s innovation or imitation propensities

Introduction The capacity for cumulative culture depends on the interplay between social learning and innovation, yet the social-ecological factors that shape individual variation in these processes remain poorly understood. Children’s position within peer networks has been theor...

Expression Analysis of microRNAs in Peripheral Blood Mononuclear Cells in Type 2 Diabetes

MicroRNAs (miRNAs) are involved in the regulation of glucose metabolism and inflammatory processes associated with type 2 diabetes (T2D) and have potential as biomarkers and therapeutic targets. We analysed the expression of miR-155-5p, miR-141-3p, miR-15b-5p, miR-18a-5p, and miR...

Machine Translation for Sign Languages

Sign language machine translation has progressed substantially over the past decade, evolving from isolated sign recognition to end-to-end translation systems. Advances in pose estimation, transformer architectures, and large-scale dataset collection have driven progress, yet cha...

Adaptive-Robust Mean-CVaR Optimization for Crude Oil Blending and Scheduling under Property Uncertainty

Abstract Refineries stabilize the crude distillation unit feed by blending grades delivered under long-term contracts with cargoes purchased on the spot market. The true boiling point (TBP) yields of a delivered batch deviate from the nominal assay, and an occasional spot cargo d...

Nonlocal Scattering Problem in Harmonic-Oscillator-Based R-matrix Approach

Abstract A nonlocal two-body scattering problem for optical potentials of the Perey–Buck type is solved within a newly-developed version of the R -matrix approach. The approach is based on harmonic oscillator expansion of the scattering wave functions within the range of the opti...

Agency-structure: Tourists' sustainable food journey

This study integrates visual and qualitative methodologies within a longitudinal framework to examine how agency and structure shape tourists' sustainable healthy food consumption before, during, and after holidays. Pre-holiday food practices are influenced by intergenerational k...

Closed‐form solutions for dynamic punching shear assessment in flat slabs subjected to sudden column removal

Abstract Simplified closed‐form equations are commonly used in structural design to prevent punching shear failures of concrete flat slabs supported on columns in permanent and transient situations, whereas more advanced methods are generally used in verifications at accidental d...

Early onset of the hot circumgalactic medium around Milky Way galaxies

Abstract Hot coronae are key regulators in Milky Way (MW)-type galaxy formation and are thought to emerge once a galaxy’s dark matter halo crosses a critical mass threshold, Mvir ~ 1012 M⊙, so that accretion shocks can heat infalling gas to virial temperatures, Tvir. Here we inve...

Are UK Research Priorities Aligned? Comparing the Research Priorities of the Down Syndrome, Fragile X Syndrome and Williams Syndrome Communities, With the Research and Funding Landscape

ABSTRACT There is a lack of understanding of how research activity in learning disability compares with community research priorities in the United Kingdom, where an estimated 1.5 million people live with a learning disability. Using Down syndrome (DS), Fragile X syndrome (FXS) a...

Within‐Sector Job Mobility and Worker Outcomes in England's Adult Social Care Sector

ABSTRACT England's adult social care sector faces persistently high staff turnover. This article examines the effects of individual‐level within‐sector job mobility on hourly pay and working hours and identifies the employer types and contractual arrangements that attract such mo...

Contact Resistance at Interfaces Buried Within Organic Transistors Imaged Using Scanning Microwave Impedance Microscopy

Contact resistance has been a consistent challenge in the 40-year history of the organic thin-film transistor (OTFT). The problem arises because contact resistance at the metal electrode/organic interface is an amalgamation of physical phenomena: From ubiquitous defect states and...

The effects of war and displacement on Syrian refugee children: risk and resilience

Millions of children across the world are affected by war and displacement. In addition to having experienced traumatic war-related events, many refugee children end up living in adverse conditions with little access to basic resources. It is well established that children expose...

A flow shop scheduling problem incorporating a reconfigurable material handling Robot: A constraint programming approach

A reconfigurable manufacturing system (RMS) is a new paradigm for the manufacturing environment to respond to unpredictable market change and frequent new product introduction. One of the components of an RMS is a reconfigurable material handling system (RMHS). This paper investi...

Multivariate genetic analyses test for the presence of a general ‘ n ’ factor underlying neurodevelopmental conditions

Abstract Background Neurodevelopmental conditions often emerge early in life and have substantial genetic influences. There are significant genetic correlations between neurodevelopmental conditions, such as between autism spectrum disorder (Autism) and attention deficit‐hyperact...

Hypokinesia and bradykinesia in Parkinson’s disease are consistent with reduced motor vigour, not an impaired capacity to generate and transmit neural drive to muscle

Abstract Hypokinesia and bradykinesia in Parkinson’s disease have been attributed to reduced motor vigour, an account that assumes the neural drive to muscle is intact but inappropriately scaled; an alternative is that generation of the drive is itself impaired. We recorded high-...

An Anomic Thesis and Agent-causal Libertarian Accounts of Free Will

Abstract Randolph Clarke argues that the following thesis is false: If incompatibilism is true, then for a human agent to perform a directly free action, the agent’s exercise of causal power must not be governed by any laws of nature, not even by probabilistic ones. That is, he a...

Self-interacting dark matter promotes bar formation in disk galaxies

Abstract Despite its remarkable success on large scales, the standard ΛCDM paradigm faces persistent small-scale challenges that have motivated alternative models for the dark sector. Self-interacting dark matter (SIDM) offers a compelling possibility, in which dark matter partic...
