Galois theory under inverse semigroup actions

Wesley G. Lautenschlaeger · Thaísa Tamusiunas

We develop a Galois theory of commutative rings under actions of finite inverse semigroups. We present equivalences for the definition of Galois extension as well as a Galois correspondence theorem. We also show how the theory behaves in the case of inverse semigroups with zero.

From Children to the Entire Population: Policy Lessons From a Decade of Successful Sodium Intake Reduction in South Korea

Yoonna Lee · Ki-Chul Sung · Jae-Sik Jang · Jong Seon Park · y 5 más

High sodium intake increases blood pressure and cardiovascular risk, making reduction a highly cost-effective public health strategy. South Korea, which historically had one of the highest global sodium consumption rates, implemented a comprehensive policy to reduce sodium intake, beginning with a child-focused, legisl...

Mechanisms of fast CO2 fixation reaction by enoyl-CoA carboxylases/reductase

Jacob SUMMERS · Daniele DE SANCTIS · Niko VLAHAKIS · Victoria KNIGHT · y 3 más

Carbon dioxide (CO2) is an atmospheric greenhouse gas that feeds all life, plays a critical role in global warming, and could constitute an inexpensive carbon source for future sustainable industries. While synthetic chemistry lacks suitable catalysts to functionalize carbon dioxide in mild reaction conditions, autotro...

DETERMINATION OF SUB-MILLISECOND PROTEIN DYNAMICS TRIGGERED BY pHP-CAGED ATP

KONSTANTINOS MAGKAKIS · Fredrik ORADD · Matteo LEVANTINO · Fatemeh SABZIAN MOLAEI · y 3 más

Adenosine triphosphate (ATP) drives many critical cellular processes. We have used laser-induced release from a caged, inactive form of ATP (NPE-caged) followed by short X-ray pulses at the dedicated time-resolved X-ray solution scattering (TR-XSS) beamline ID09 at ESRF-EBS to study protein conformational change in rea...

DistributedEstimator: Distributed training of quantum neural networks via circuit cutting

Prabhjot Singh · Adel N. Toosi · Rajkumar Buyya

Circuit cutting decomposes a large quantum circuit into smaller subcircuits executed independently; expectation values are recovered by classically combining subcircuit outcomes. Prior work characterises cutting overhead via subcircuit counts and sampling complexity, but its end-to-end impact on iterative, estimator-dr...

Deformation in the Earth’s crust localizes onto faults that may rupture rapidly producing earthquakes, or undergo slow aseismic slip that may or may not accelerate into coseismic slip. Our goal is to provide the first quantitative laboratory observations of the full displacement field in rocks before and during coseism...

Tracking the low temperature lattice ordering and strain distribution during Verwey phase transition in magnetite

Mateusz GALA · Andrzej KOZLOWSKI · Guillaume BEUTIER · Luc ORTEGA · y 5 más

We will investigate the coupling between strain and the metal-insulator phase transition (the Verwey transition) in the canonical compound, magnetite. We have shown (HC-4565) that strain caused by lattice imperfections affects the transition temperature, TV as the externally induced strain does. We have also proved bef...

Nonlinear Rayleigh quotient optimization

Flavio Salizzoni · Luca Sodomaco · Julian Weigert

Rayleigh quotient minimization deals with optimizing a quadratic homogeneous function over a sphere. Its critical points correspond to the normalized eigenvectors of the symmetric matrix associated with the quadratic form. In this paper, we consider a homogeneous polynomial objective function $f$ over a sphere, a proje...

A hierarchical, pH-responsive nanocomposite hydrogel platform for synergistic microenvironment reprogramming and attenuation of inflammatory periodontal bone loss

Yixin Zhang · Xiaodong Jing · Xu Wang · Zhengchu Zhang · y 6 más

Conventional periodontitis therapies are limited by their inability to concurrently address the interconnected challenges of persistent bacterial infection, excessive oxidative stress, and immune dysregulation. To overcome this, we developed an injectable, pH-responsive nanocomposite polypeptide hydrogel, PepGel@ZnO-PL...

CHRONOS

Jessica MCBECK · Benoît CORDONNIER

Many fundamental processes evolve over months and years, including 1) the strengthening of fault zones in the interseismic period between earthquakes, 2) the sequestration of carbon-bearing minerals in subsurface geologic reservoirs, 3) charge cycling in batteries, 4) the reactions between mixing magmas preceding volca...
