Electrodynamic ratchet motor

Physical Review E, 2009
Brownian ratchets produce directed motion through rectification of thermal fluctuations and have been used for separation processes and colloidal transport. We propose a flashing ratchet motor that enables the transduction of electrical energy into rotary micromechanical work.

Climate Delegates' Views on the Dynamic Incentive Mechanism Under the Paris Agreement

Global Policy, EarlyView.
ABSTRACT The Paris Agreement establishes a bottom‐up global action plan with the aim of limiting global warming to well below 2°C above preindustrial levels, where countries should pledge Nationally Determined Contributions (NDCs) of the highest possible ambition. The design of the agreement gives national authorities the freedom to decide on their own

When Accounting Qualities Collide: Accruals Quality, Comparability and Information Risk in SEO Underpricing

Accounting &Finance, EarlyView.
ABSTRACT We examine how accounting quality attributes jointly mitigate underpricing associated with two dimensions of information risk in seasoned equity offerings (SEOs). In information environments with relatively more potent information asymmetry, the evidence suggests that accruals quality and accounting comparability act as substitutes; i.e ...

DHX15 affects AML1‐ETO9a splicing together with HNRNPL, RBM33 in AML1‐ETO‐positive acute myeloid leukaemia

British Journal of Haematology, EarlyView.
Moderate DHX15, HNRNPL and RBM33 expression drives predominant AML1‐ETO mRNA production, while elevated expression of them promotes generating more AE9a mRNA (Aspartic acid ‐ Glutamic acid ‐ Alanine ‐ Aspartic acid sequence)(messenger ribonucleic acid).

Budding speciation, mitochondrial capture and introgression between surface and cave lineages in the Asellus aquaticus species complex

Cladistics, EarlyView.
Abstract Replicated pairs of ancestral and evolutionarily derived populations provide opportunities to test hypotheses about the deterministic laws of evolution. The Asellus aquaticus species complex is an invertebrate model system with several independent surface‐to‐cave transitions and a complicated and unresolved evolutionary history.

Scientists’ warning on the global destruction of rock outcrop ecosystems

Conservation Biology, EarlyView.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Ratcheting of Steel Samples Undergoing Asymmetric Loading Cycles at Elevated Operating Temperatures: Analytical and Numerical Assessments

Applied Sciences
The present study intends to assess the ratcheting response of SA508 and SA333 steel alloys subjected to asymmetric loading cycles at various operating temperatures of 298, 573, and 623K through a hardening framework developed by Ahmadzadeh–Varvani (A-V)

Deregulation, government failure, and tragedy: The Report of Phase 2 of the Grenfell Tower Inquiry

Economic Affairs, EarlyView.
Abstract The Inquiry into the fire at Grenfell Tower, London, in 2017 has exposed the failures that led to the tragedy in a commendably exhaustive manner. But the explanation of those failures is seriously inadequate. First, they are attributed to deregulation, when the Inquiry itself details the ways in which the cladding of the building was subject ...

Evaluation of the ratcheting behavior of Cr-Mo steel used in CNG tank

Results in Engineering
Compressed natural gas (CNG) tanks, due to the frequent filling and emptying during their service life, are constantly subjected to fatigue loading on the tank's wall, which causes premature failure.
