Graded Differential Polynomial Rings

ABSTRACT We study differential polynomial rings over ‐graded rings, where is an arbitrary group. We show that admits a ‐grading compatible with that of if and only if is a ‐derivation for some , and that this grading is unique once is fixed; if , then is itself uniquely determine...

A short note on differential equations and on Geometry

A short note on differential equations. We add some lines of interest about Some topics in Geometry.

A niche construction-based approach to evolution by natural selection without reproduction—proof of concept and implications

Abstract In past decades, conceptual analysis has established that evolution by natural selection (ENS) can occur without reproduction (Bouchard 2008 Philos. Sci. 75, 560–570 (doi:10.1086/594507); Papale, 2021 Synthese 198, 10 429–10 455 (doi:10.1007/s11229-020-02729-6)). The aim...

Short Communication on Email Management Systems

We present the opportunity to Manage Emails with More in-depth Computing Systems. Many options and examples are of interest.

Proper affine deformations of positive representations

Abstract We define, for every positive Anosov representation of a nonabelian free group into , a family of ‐valued cocycles which induce proper affine actions on . We construct fundamental domains in bounded by generalized crooked planes for these affine actions, and deduce that...

Machine Learning on Heterogeneous, Edge, and Quantum Hardware for Particle Physics

The next generation of particle physics experiments will face an era of challenges in data acquisition, due to unprecedented data rates and volumes along with extreme environments and operational constraints. Harnessing these data for scientific discovery demands real-time infere...

Short Communication on Objects Found on Road

We have found some Objects on Road in Montreal City. Some Remarks are made.

Reflector‐Free, Highly Confined Love‐Like SAWs Enabled by a Phononic Metasurface for Real‐Time Monitoring of Cell Dynamics

ABSTRACT Surface acoustic wave (SAW) devices are widely used in sensing and biosensing but generally suffer from strong attenuation in liquid environments. Conventional approaches rely on reflectors to reduce these losses, yet these components remain difficult to optimize: limite...

Psychometric Properties of the French Version of the Provider Co-Management Index-RN

Background Strengthening primary care through team-based models is a global priority as strong primary care systems are consistently associated with improved outcomes. The Provider Co-Management Index for Registered Nurses (PCMI-RN) is a validated instrument measuring co-manageme...

A ribosomal pseudouridine drives an oncogenic translation program

Dynamic ribosome heterogeneity has emerged as a potential layer of translational regulation, but whether variation in ribosomal RNA (rRNA) modification stoichiometry can selectively control the translation of mRNAs with shared encoded features remains unclear. Here we show that S...

Cross-cultural adaptation of the Athlete Diet Index, a web-based dietary assessment tool for athletes

Background The literature suggests that many athletes fail to meet health and sport-specific dietary recommendations which may negatively impact their overall health and performance. Moreover, completing a proper assessment of an athlete's diet is complex; the quality and validit...

Redefining Vacuum and the Cosmic Fabric,

Porous Superfluid Vacuum Theory (PSVT) presents a novel physical framework that redefines the structural nature of the vacuum and spacetime by conceptualizing cosmic space as a quantum superfluid, with ordinary matter acting as a porous medium within it. Moving systematically fro...

Analysis of sustainable development: an overlapping generations model of agricultural households in developing countries

Abstract This article examines the effectiveness of individual transferable quotas (ITQs) in promoting sustainable resource management within an overlapping generations economy where agricultural producers face credit constraints. The analysis shows that, although ITQs restore th...

Exploring needs and priorities in digital health management for rare disease patients and their caregivers: A mixed-methods study

Rare diseases affect millions worldwide and are associated with long diagnostic delays, limited access to treatments, and substantial challenges in daily care and coordination. Digital health technologies, including mobile apps, tele health, and data‑sharing platforms, offer oppo...

Emergent properties of urban landscapes shape urban eco-evolutionary dynamics

Abstract Context Urbanization transforms natural ecosystems into heterogeneous and fragmented landscapes, creating novel selective pressures that can drive eco-evolutionary dynamics. However, the specific role of urban spatial structure in shaping these dynamics remains poorly un...

The impact of physical activity and exercise timing on metabolic health among individuals at high risk of type 2 diabetes

The timing of physical activity and exercise has been suggested to play a role in metabolic health. This narrative review synthesises current evidence on the impact of habitual physical activity and exercise timing on glucose homeostasis and insulin sensitivity, blood lipids and...
