Journal of Applied Polymer Science, EarlyView.Cooling holes provide a simple passive cooling strategy for polymer spur gears, reducing maximum operating temperature by up to 9.39% while introducing a measurable gear mesh stiffness penalty. A validated response‐surface model reveals how hole size and location govern this thermal–mechanical trade‐off, enabling design optimization for thermally and ...

Quantum Heat Current in Terahertz‐Driven Phonon Systems
Advanced Physics Research, EarlyView.We develop a quantum mechanical description of ultrafast thermodynamics on the example of a laser‐excited phonon mode. We show that the resulting quantum heat current exhibits non‐Markovian dynamics, which can be controlled by the pulse length. ABSTRACT The advent of high‐intensity ultrafast laser pulses has opened new opportunities for controlling and

ON VON NEUMANN REGULARITY, INJECTIVITY AND FLATNESS [PDF]
application/pdfIt is still unknown whether a SF-ring A (every simple left or right A-module is flat) is von Neumann regular. The following non-trivial generalization of regular rings is considered: write "￥A satisfies(*)" if, for any maximal right ideal ＄

The Anatomical Record, EarlyView.Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Clinical Advances in Periodontics, EarlyView.Abstract Background Conventional envelope flap techniques for implant placement in edentulous mandibles are associated with greater postoperative morbidity, especially in elderly patients or those with anatomical limitations. Minimally invasive alternatives aim to preserve soft tissues and reduce complications, enhancing clinical predictability ...

Uniqueness in π-Regular Unital Rings [PDF]
, 2017 We establish that a ring is uniquely π-regular if, and only if, it is a division ring. This somewhat improves on our result proved for uniquely von Neumann regular rings in Palestine.departmental bulletin ...

In Vivo Cytoskeletal AMPA Receptor Transport Imaging in C. elegans
Cytoskeleton, EarlyView.ABSTRACT Long‐distance intracellular transport of ionotropic glutamate receptors (iGluRs) is essential for proper excitatory synaptic function underlying learning and memory. Many neuropsychiatric and neurodegenerative conditions have abnormal iGluR transport and trafficking, leading to an intense interest in the mechanisms and factors regulating these

Semisimple Rings and Von Neumann Regular Rings of Generalized Power Series
Journal of Algebra, 1997 Let \((S,+,\leq)\) be a strictly ordered monoid and let \(R\) be a ring. The author defines the ring of generalized power series \(A=[R^{S,\leq}]\), with coefficients in \(R\) and exponents in \(S\) as the set of all functions \(f\colon S\to R\) such that \(\text{supp}(f)\) is artinian and narrow. The following main theorem is proved. Let \(R\) contain

Towards a Mean‐Field Braginskii Model for Stellarators
Contributions to Plasma Physics, EarlyView.ABSTRACT Experiments in the stellarator Wendelstein 7‐X indicate that particle drifts have a significant impact on the plasma in the scrape‐off layer. However, drift effects have been absent in the mean‐field transport codes such as EMC3‐Eirene. For this reason, we present the first steps towards a mean‐field model that incorporates drifts. The code is
