A Diamagnetic Six-Coordinate Ag(III) Complex

Abstract The octahedral complex AgIII(CF3)3tpy (2Ag), attainable from AgIII(CF3)3py (1Ag) and terpyridine (tpy), has been isolated and characterized using NMR spectroscopy and Sc-XRD. Strikingly, 2Ag proved to be diamagnetic and showed tridentate coordination of the tpy ligand, t...

Temperature sensitivity of snow viscoplasticity: Evidence from controlled creep experiments

Abstract. Snow is a warm, porous material whose densification under its own weight is highly temperature-dependent. Despite decades of research, reported activation energies for snow viscoplasticity remain highly scattered, ranging from 40 to 600 kJ mol-1. We quantified the tempe...

Quasi-static compression performance of multiphase 3D-printed PLA–PETG interpenetrating TPMS structures

Triply Periodic Minimal Surface (TPMS) lattices are attractive cellular architectures owing to their smooth, curvature-continuous geometry, high surface-to-volume ratio, and efficient load-bearing behavior. TPMS structures are widely investigated for lightweight and energy-absorp...

Metformin reverses lymphatic mitochondrial dysfunction induced by 5-FU chemotherapy

Abstract In western countries, secondary lymphedema often occurs after cancer treatments. However, lymphedema appears months, sometimes years after treatment suggesting that it is not only a side effect of surgery and may be promoted in part by cancer treatments. In this study, w...

Replicability of agent-based simulations: a case study with a SEIRS epidemiological model

Reproducibility is not only a cornerstone of the advancement of science, but also of scientific credibility. However, it remains a persistent challenge across many disciplines, and it is now referred to as the “reproducibility crisis.” This issue is particularly relevant in compu...

Antioxidant and Anti-Inflammatory Properties of Natural Compounds—2nd Edition

Plant natural remedies have formed the cornerstone of traditional healthcare, particularly in skincare, since antiquity, spanning Traditional Chinese Medicine, Ayurveda, Greco-Roman rituals, and Mediterranean practices [...]

A cytidine deaminase biodegrader sensitises multiple cancer types to deoxycytidine analogue-based chemotherapies

Abstract Deoxycytidine (dC) analogues are widely used to treat solid tumours and blood cancers. However, their clinical efficacy is often limited by resistance mediated by cytidine deaminase (CDA), which converts these drugs into inactive metabolites. Existing CDA inhibitors have...

Distributed Phase-Shedding: A Scalable Solution for Automotive Microprocessor Power Supplies

The increasing computing power required by autonomous vehicles imposes stringent requirements on automotive microprocessor power supplies in terms of efficiency, scalability, and fault tolerance. Conventional phase-shedding strategies for multiphase converters rely on centralized...

Scanning and active sampling behaviours emerge from conserved insect neural circuits

Navigating insects often pause and rotate to sample their surroundings, behaviours termed scanning. These and other active sampling behaviours embody navigational uncertainty and are key for spatial learning, yet their neural basis remains unclear and existing models impose scann...

Marine arsenate evolution during Proterozoic oxygenation events and implications for biological phosphate metabolism

Abstract Earth’s atmosphere and oceans experienced two major episodes of ocean-atmosphere oxygenation that transformed the planet and shaped the evolution of the oxygen-rich biosphere between 2.45 and 0.541 billion years ago (Ga). These changes increased the abundance of oxidized...

L’indépendance écossaise à l’ombre du Brexit

En ouverture de L’indépendance écossaise à l’ombre du Brexit, Juliette Ringeisen-Biardeaud note avec espièglerie que le référendum d’indépendance de 2014 a révélé au monde entier « qu’Ecosse et Ang...

Quantum Graph Theory by Example

Quantum graphs have been introduced by Duan, Severini, and Winter to describe the zero-error behaviour of quantum channels. Since then, quantum graph theory has become a field of study in its own right. A substantial source of difficulty in working with quantum graphs compared to...

Universal random matrix behavior of a Fermionic quantum gas

Since its initial use by Wigner in describing heavy atom spectra, random matrix theory (RMT) has found applications and revealed universal laws in diverse physical contexts, from quantum field theory to disordered systems and wireless communications. A particularly compelling app...

Mechanism‐Guided Engineering of Upconversion Nanoparticles for Antibacterial Phototherapy: From Photonic Principles to Translational Nanosystems

The emergence of multidrug-resistant (MDR) bacteria necessitates the development of next-generation antimicrobial strategies beyond conventional antibiotics. Upconversion nanoparticles (UCNPs), owing to their anti-Stokes luminescence under near-infrared (NIR) excitation, offer a...

Mechanisms of Cyclonic Meander Formation in the Western Yucatan Channel

Cyclonic meanders in the western Yucatan Channel generate intense frontal conditions associated with strong isopycnal uplift, enhanced vertical shear, and local transformation of Caribbean waters into Yucatan Gulf Common Water. Observational composites further show that strong me...
