Morphogenesis of bacterial colonies in liquid crystalline environments

Natural bacterial habitats are often complex fluids with viscoelastic and anisotropic responses to stress; for example, they can take the form of liquid crystals (LCs), with elongated microscopic constituents that collectively align while still retaining the ability to flow. Howe...

Combined Transcriptional and Metabolic Analysis of the Differences in Salt Tolerance Responses of Tillers in Different Rice Varieties

<title>Abstract</title> Background Soil salinization is a significant factor contributing to the reduction of arable land. To enhance rice productivity in saline-alkali soils, understanding the salt tolerance mechanisms of rice varieties is essential. This study focused on invest...

Modeling the Subglacial Sediment System of the Finnish Lake District Ice Lobe During Deglaciation

Abstract. The systematic connection of glacial conditions in ice models with subglacial geomorphological observations has been limited by an inability to model subglacial sediment processes. The Finnish Lake District Ice Lobe (FLDIL) presents an opportunity to apply new model app...

Shape-Induced d-BandCenter Optimization ofPdBiNi Nanocubes for Exclusive Oxidation of Glycerol into C3 Products

Abstract Electrocatalytic oxidation of glycerol toward high-value C3 products on Pd-based catalysts presents a promising strategy for upgrading and converting glycerol. However, C3 intermediates often adsorb too tightly on Pd-based catalyst surfaces during glycerol oxidation, lea...

MARMOT: masked autoencoder for modeling transient imaging

Abstract Pretrained models have recently emerged as effective priors for a wide range of vision and computational imaging problems. Transient measurements have emerged as a new imaging modality, in which a time-resolved sensor records photon counts over time bins. In confocal non...

Fine-tuning an ECG foundation model to predict coronary CT angiography outcomes

<title>Abstract</title> Coronary artery disease (CAD) remains a major global health burden. Accurate identification of the culprit vessel and assessment of stenosis severity are essential for guiding individualized therapy. Although coronary CT angiography (CCTA) is the first-lin...

Performance guarantees of light-cone variational quantum algorithms for the maximum cut problem

Abstract Variational quantum algorithms (VQAs) are promising to demonstrate the advantage of quantum computing over classical computing in practical applications, such as the maximum cut (MaxCut) problem. However, current VQAs such as the quantum approximate optimization algorith...

MOFU: Development of a MOrphing Fluffy Unit with expansion and contraction capabilities and evaluation of the animacy of its movements

Robots designed for therapy and social interaction are often intended to evoke a sense of “animacy” in humans. While many robots have been developed to imitate life-like appearance and joint movements, relatively little attention has been given to the effect of whole-body expansi...

Arduino-controlled pulse electrodeposition for low-cost zinc coating on stainless steel

<title>Abstract</title> Metal corrosion is a major challenge in the manufacturing sector. Pulse electrodeposition (PED) is a promising effective technique for metal corrosion protection; however, the coating quality depends on the PED parameters. This study involved metal corrosi...

Hybrid Optomechanical Cooling with Kerr Magnons and Squeezed Vacuum

Abstract Ground-state cooling is essential for accessing the quantum regime and enabling quantum control of macroscopic systems. However, achieving optomechanical cooling in the unresolved-sideband regime, where the mechanical frequency ω b is smaller than the cavity linewidth κ...

Dispatch or Hold? An Inverse Optimization and Reinforcement Learning Approach for Multiobjective On-Demand Delivery

In large-scale on-demand food delivery systems, dynamic order dispatching needs to balance immediate dispatch and order holding amid competing objectives, including delivery efficiency, service timeliness, and courier utilization. Holding certain orders for future consolidation m...

Characterizing the impact of incorporating spatially aggregated human mobility data into infectious disease models

Abstract Models of infectious disease dynamics should align the spatial scale of mobility data to the scale of travel relevant to infer disease introduction events and subsequent local transmission. Despite this, the biases of spatially aggregating mobility data, which are more c...

Effect of alpha-lipoic acid on atrial fibrillation and biomarkers of myocardial injury in patients undergoing coronary artery bypass surgery: study protocol of a randomized, double-blind, placebo-controlled clinical trial

<title>Abstract</title> <bold>Background</bold> : Coronary artery bypass grafting (CABG) is associated with several postoperative complications, notably atrial fibrillation (AF), which may arise due to myocardial reperfusion following ischemia and the resulting inflammatory respo...

Quasinormal modes of a charged spherically symmetric black hole in bumblebee gravity

Abstract Lorentz symmetry may be violated at the Planck scale. In the bumblebee model, a vector field acquires a nonzero vacuum expectation value, spontaneously breaking Lorentz symmetry. We study quasinormal modes of a charged spherically symmetric black hole in this framework,...

A global dataset of forest disturbance regimes derived from satellite biomass observations

Abstract. Forests play a central role in the global carbon cycle by serving as critical carbon sinks for atmospheric CO2. Yet, the stability and continued capacity of these sinks are increasingly threatened by a growing number of disturbances. Accurately representing the stochast...

Nonparametric estimation of the jump rate in mean field interacting systems of neurons

We consider finite systems of $N$ interacting neurons described by non-linear Hawkes processes in a mean field frame. Neurons are described by their membrane potential. They spike randomly, at a rate depending on their potential. In between successive spikes, their membrane poten...

Locality in Residuated-Lattice Structures

Many-valued models generalise the structures from classical model theory by defining truth values for a model with an arbitrary algebra. Just as algebraic varieties provide semantics for many non-classical propositional logics, models defined over algebras in a variety provide th...

Unitary quantum matter-bounce in a universe with a positive cosmological constant

Geometry of essential matrix ranges and the Smith–Ward problem for operator systems

Abstract A ‐tuple of bounded linear selfadjoint operators acting on an infinite‐dimensional separable Hilbert space is said to have the Smith–Ward property if the identity map of the image of the operator system in the Calkin algebra has a completely positive lift. In this paper,...
