Solving the standing-start paradox in track cycling

Abstract Standing starts in track cycling appear paradoxical: a departure ‘from rest’ can exhibit a non-zero bike velocity at the official signal. We resolve this apparent contradiction by identifying a brief transitional regime, initiated around the gate-release window and prece...

Collaborative approaches to reducing food loss and waste: a systematic literature review

Food loss and waste (FLW) remains a critical sustainability challenge across food supply chains (FSC), affecting resource efficiency, food security, and environmental outcomes. Although collaboration is frequently invoked in proposed FLW solutions, its role has not been systemati...

Protocols on X-ray Absorption Spectroscopy Measurement and Interpretation

Abstract Understanding the local electronic and atomic structure of materials is central to modern physics, chemistry, materials science, and nanotechnology. X-ray absorption spectroscopy (XAS) provides element-specific insight into these local environments through core-level X-r...

Actin and myosin dynamics during epithelial remodeling in avian gastrulation

Epithelial remodeling is powered by contractile forces exerted by the actomyosin cytoskeleton. In invertebrates, pulsatile contractile flows of the medio-apical actomyosin cortex have been shown to be critical in promoting junction contraction, ultimately driving cell rearrangeme...

Evaluating the Validity of Model Organisms: A Review and a New Framework for Biologists

Model organisms are central to biological research. Living organisms are models in the sense that the knowledge gained from their study is meant to be generalized. For example, experiments conducted on Drosophila or nematodes bring general knowledge on phenomena such as cell migr...

LDL Cholesterol Lowering With Evolocumab Before Percutaneous Coronary Intervention for Acute Myocardial Infarction

Importance: Proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibition is recommended as second- or third-line lipid-lowering therapy after myocardial infarction (MI), resulting in prolonged periods of inadequate low-density lipoprotein cholesterol (LDL-C) control. Whether...

Logrolling affects the relative performance of majority and unanimity rule

Abstract We consider a committee facing binary decisions on a number of proposals. If members vote sincerely and payoffs are symmetrically distributed, we show analytically that simple majority rule is the best q-majority rule in an aggregate or expected payoff sense. We argue th...

Effective integration of Lie type algebras

Abstract This is a short survey on the recent developments made in the integration theory with effective formulas of algebraic structures stronger or higher than Lie algebras. This article is part of the theme issue ‘Derived Lie algebras in geometry and topology’.

Symmetry-AdaptedRelaxation Theory (SART): VariationalEmbedding for Convergent Infinite-Order Induction without Overpolarization

Abstract The induction part of intermolecular interaction energy describes the effect of the mutual polarization of subsystems. Low-order induction effects can be reasonably described by symmetry-adapted perturbation theory (SAPT), but the capture of important higher-order polari...

Guidelines for Studying Mutagenesis in Quiescent Schizosaccharomyces pombe

All living organisms can enter a non-dividing state known as quiescence, which often functions as a survival strategy. In many cases, quiescent cells retain the ability to re-enter the cell cycle when conditions become favorable. Therefore, preserving the integrity of non-dividin...

The rise of carnivoran mammals in Europe through the lens of body mass

Carnivoran mammals (cats, dogs, bears, seals, etc.) and their kin radiated during the Palaeogene, among other carnivorous clades (hyaenodonts, mesonychians, and oxyaenodonts). This radiation has often been framed as a competition ultimately won by carnivorans, but the data suppor...

Fertility-Sparing Management of Atypical Hyperplasia and Endometrial Cancer from the Perspective of Molecular and Hormonal Profiles: A Meta-Analysis-Driven Framework

Background/Objectives: The prognostic and predictive values of biomarkers in fertility-sparing management of atypical hyperplasia (AH) and endometrial cancer (EC) remain ill-defined. We aimed to identify the impact of tumour profiles on oncologic and reproductive outcomes to info...
