Calculating resonance position and lifetime using modified smooth exterior scaling for piecewise one-dimensional potentials

Abstract The primary objective of this paper is the systematic investigation of the applicability and numerical behaviour of the modified smooth exterior scaling (MSES) framework for piecewise and non-trivial one-dimensional problems. Studying these piecewise potentials is import...

John Derek Smith

Abstract In the 1950s and 1960s John Smith pioneered the studies of RNA sequence and function and, in doing so, laid the foundations for the subsequent immense flowering and power of genomic sequencing as it is practised today. First and foremost John was a meticulous experimenta...

Direct speciation of ultra-trace platinum in marine ferromanganese oxides by wavelength-dispersive XAFS

Abstract Ultra-trace platinum (Pt) in marine ferromanganese oxides (FMOs) has remained inaccessible to direct XAFS analysis because of its extremely low abundance and severe interferences from co-existing elements. We achieved the first direct speciation of Pt at the 1 μg g−1 lev...

Electrically activated quasi-BICs in metasurfaces through atomically thin semiconductors

Abstract A new class of electrically tunable nanophotonic devices is presented combining atomically thin 2D materials and metasurfaces supporting quasi bound states in the continuum, with appealing potential applications.

The cost of events in temporally-resolved energy system models: a stochastic programming approach

Abstract To deal with random exogenous events, energy systems require the ability to flexibly adjust their operational schedule. Here we explore how such events can be incorporated into temporally resolved energy system models as forced deviations from planned operation at random...

Wolves increase germination speed and success of blueberries

Abstract Seed dispersal plays a key role in facilitating important ecological processes that reduce plant competition, parasitism and predation while promoting gene flow and biodiversity. In many ecosystems across North America and Eurasia, wolves consume fruits when available. H...

Variable arithmetic periods : A Multiscale Generalization of Ren's Image-Size Method to Logarithmic Depth Using Harmonic Fiber Weighting

This work develops a new method for estimating the size of iterated images of the quadratic map sending x to x squared plus one over finite prime fields, with the aim of controlling the smallest prime carrying a prescribed exact critical period. The approach departs from Ren’s me...

Presence of human adenovirus 36 in an urban rodent population

Abstract Adenovirus 36 (AdV36) is a virus associated with respiratory and gastrointestinal infections in humans; interestingly, it also exhibits adipogenic potential, as demonstrated in experimental rodent infections and in human adipose tissue. To detect AdV36 in faecal samples...

Estimating the undercount of intimate partner violence using multiple systems data

Abstract Reliable estimation of the underreported incidence of intimate partner violence (IPV) is essential to understand the true magnitude and public health burden. An integrated data system that combines multiple sources is commonly used to estimate such a hard-to-count popula...

Complex breeding phenological shifts of neotropical birds across space and time

Climate change is altering breeding phenology patterns in different ways across regions, periods and species. We examined spatial and temporal variation in the breeding phenology of four Neotropical birds, specifically testing whether the magnitude of phenological shifts increase...

Graph-based complexity and computational capabilities of proteinoid spike systems

Abstract Proteinoid microspheres exhibit oscillatory electrical dynamics that encode rich temporal structure. We analyse five proteinoid spike-train datasets using a two-step nonlinear transformation based on spiral sampling and significant-digit extraction, producing a multi-nod...

Skin displacement and velocity contribute to perception of force direction: insights from illusory tactile pulling sensations

Abstract Humans perceive tangential force at the fingertip through skin deformation characterized by kinematic components, such as displacement, velocity and acceleration. However, their respective contributions to the perception remain unclear because these components typically...

Do weather-related extreme events influence climate-related opinions? The case of the 2019–2020 Australian Black Summer bushfires

Abstract We report three studies examining the impact of the 2019–2020 Australian bushfires, known as the Black Summer, on Australians’ climate-related opinions. Study 1 was conducted before the peak of the bushfires, whereas studies 2 and 3 were conducted afterwards. In all stud...

Determinants of highly pathogenic avian influenza spread during bird migration

Abstract Migratory waterfowl are central to the global spread of the Goose/Guangdong lineage of H5 highly pathogenic avian influenza (HPAI), yet the parameters and processes shaping their role remain poorly understood, with evidence scattered across studies focused on narrow sets...

Near-peer mentoring influences self-regulated learning strategies among medical graduates in high-stakes exams

Abstract INTRODUCTION: The Philippine Physician Licensure examinations is a high-stakes examination needed to practice medicine in the Philippines. Prior studies have indicated that performance in examinations might be influenced by student self-regulated learning (SRL) strategie...

Analysis of Critical Points in a Permutation Model on Hierarchical Lattices by Real-Space Renormalization Group

The permutation model is a classical spin system where elements of the symmetric group interact with one another. The partition function of this model is directly related to the entanglement structure of random quantum circuits and random tensor networks. In these contexts, the e...

Racially minoritised workers’ incivility experiences, and consequences within maternity settings: a multimethod longitudinal qualitative exploration

Abstract Background Workplace incivility is a global concern in healthcare, undermining staff wellbeing, organisational functioning and patient safety. In England, despite National Health Service (NHS) commitments to equality and inclusion, racially minoritised staff continue to...

New mechanistic insights into the widely used LiPO2F2 additive enabled by ultra-high-resolution FTICR-MS

Understanding how electrolyte additives influence the formation and evolution of the solid electrolyte interphase (SEI) is essential for improving the durability of lithium‑ion batteries. In this work, we investigate the role of lithium difluorophosphate (LiPO2F2, LiDFP) in 1 M L...

Auriculotherapy for controlled hypotension during functional endoscopic surgery of the paranasal sinuses under general anesthesia: AuriFESS, a feasibility randomized pilot study

Abstract Background Administration of hypotensive drugs is common to induce controlled hypotension during surgery but dose-dependent side effects could limit their use. The primary hypothesis of our study is that the application of magnetic ball-plasters for auriculotherapy could...

Winter sediment resuspension in a submarine canyon drives the offshore export of toxigenic Alexandrium catenella cysts

Abstract Harmful algal blooms (HABs) caused by the toxigenic dinoflagellate Alexandrium catenella recur regularly in the Lower St. Lawrence Estuary (LSLE, eastern Canada). Using quantitative polymerase chain reaction (qPCR) to detect A. catenella DNA as a proxy for cyst abundance...
