Outcomes of therapeutic penetrating keratoplasty and deep anterior lamellar keratoplasty in acanthamoeba keratitis: A systematic review and meta‐analysis

While acanthamoeba keratitis (AK) is a sight-threatening corneal infection, a thorough comparison of the outcomes of therapeutic penetrating keratoplasty (PK) and therapeutic deep anterior lamellar keratoplasty (DALK) is lacking. We aimed to compare clinical outcomes of PK and DA...

Integrated energy management for embedded behavior prototyping in modular electric traction systems

This paper presents a compact and modular experimental platform for early-phase testing and validation of energy-aware behavior in electric autonomous and traction-based mobility systems under varying load conditions. Implemented on a 1:10-scale model, the platform integrates cam...

Sub-kJ/mol Precision at Practical Cost for Molecular Solids through Local Coupled-Cluster Approaches

Abstract Generation of numerically converged coupled-cluster reference energies of molecular crystals remains highly non-routine. Yet, such data points are critically needed as computational methodologies strive to reach correlated wave-function accuracy in condensed-phase system...

Multivalued forbidden numbers of two-rowed configurations -- the missing cases

The present paper considers extremal combinatorics questions in the language of matrices. An $s$-matrix is a matrix with entries in $\{0,1,\ldots, s-1\}$. An $s$-matrix is simple if it has no repeated columns. A matrix $F$ is a configuration in a matrix $A$, denoted $F\prec A$, i...

Exact analytical solutions for the piston effect in supercritical fluids under post-acoustic approximation — Short-time asymptotics, thermal penetration depth and comparison with the Spacelab D-2 experiments

Near the liquid–vapor critical point, fluids become highly compressible, giving rise to a special, strongly coupled thermo-mechanical process: the piston effect. In this phenomenon, a thin thermal boundary layer develops near a heated wall; owing to strong thermal expansion, this...

Mechanistic insights into potassium ion promotion of formate selectivity on copper clusters during carbon dioxide electroreduction

Enhancing efficiency and product selectivity presents a significant challenge in carbon dioxide electroreduction (CO 2 RR). While ions in the electrolyte have been shown to play an important role in the case of bulk copper electrodes, the specific effects of the cation have not b...

Desargues’s and Pappus’s hexagon theorems on translation-type surfaces in Thurston geometries

Abstract In [35] we generalized the famous Menelaus’ and Ceva’s theorems for translation triangles in each non-constant curvature Thurston geometry. In this paper based on the described method and results, we prove that the classical Desargues’s and Pappus’s hexagon theorems are...

Revealing the behavioral architecture of autonomous vehicle crashes: an interaction-based typology using real-world reports

Over recent years, hundreds of crashes have been recorded during on-road testing of autonomous vehicles (AVs), underscoring the importance of understanding how these systems behave alongside human drivers in mixed traffic. Most previous research has focused on geometric crash out...

Estimating the convex relaxation of the ideal magnetohydrodynamics equations

We investigate the explicit convex relaxation of the ideal magnetohydrodynamics equations. We provide a non-trivial lower estimate on the lamination hull and an upper estimate on the Λ-convex hull, the latter providing inequalities which will be satisfied by weak limits of weak s...

Hausdorff dimension of self-similar measures and sets with common fixed-point structure

Abstract In this paper, we study the Hausdorff dimension of self-similar measures and sets on the real line, where the generating iterated function system consists of maps that share a common fixed point. In particular, we show that out of a Hausdorff codimension-one exceptional...

Ultrastrong Au–Te bonding drives disorder in monolayer ZrTe5 on gold

Abstract Monolayer ZrTe $$_5$$ is predicted to host a large-gap quantum spin Hall phase, motivating efforts to isolate single layers of the material. Gold-assisted exfoliation produces clean monolayers of many chalcogen-terminated van der Waals crystals, but the strong Te–Au bond...

Glass Surfaces Rendered Hydrophobic by Silylation and Sol–Gel Coatings: Optical, Wetting, and Chemical Stability

Abstract This study presents a comparative evaluation of three strategies for hydrophobizing glass surfaces: direct surface silanization with dimethyldichlorosilane (DMDClSi), the application of a hybrid silica coating (H-SiO2), and the use of a hexamethyldisilazane (HMDS)-modifi...

Minimizing cutting costs in 1D rod cutting

Abstract We study a one‐dimensional rod‐cutting problem arising from an industrial setting where cutting itself carries cost . Each order specifies a length interval, and the task is to assign orders to warehouse rods so that all orders are satisfied while the number of cuts is m...

Physics-Informed Anomaly Detection in IEC 61850 Sampled-Value Networks: A Dual-Threshold Kirchhoff Residual Approach Without Machine Learning

Real-time integrity monitoring of Sampled-Values in IEC 61850-9-2 is critical for detecting cyber-physical attacks, yet the unauthenticated multicast ASN.1/BER transport leaves every in-transit frame exposed to undetected modification. However, machine-learning-based detectors re...

Modeling Incomplete Solute Mixing at Pipe Junctions in Water Distribution Networks: Parametric CFD Simulations and a Predictive Regression Approach

Abstract High-quality drinking water is essential for modern settlements, and accurate modeling of solute mixing at pipe junctions is crucial in water distribution networks (WDNs). While complete mixing is often assumed, recent studies emphasize the need to account for incomplete...

Food experience, place attachment and locavorism in urban destinations

This study investigates the role of locavorism in urban gastronomic tourism and examines its relationships with food experience, place attachment and behavioural outcomes. Addressing a gap in research on locavorism in cities, the study examines whether local food experiences infl...

A bacterial protein inhibitor of dUTPase disrupts zebrafish embryogenesis through a conserved active‐site mechanism

Abstract Deoxyuridine triphosphatase (dUTPase) is essential for DNA replication fidelity and embryonic development in metazoa, yet whether a protein inhibitor can acutely disrupt dUTPase function in a living vertebrate has not been tested. The Staphylococcus aureus Stl protein in...

One Core, Many Cures: Quantitative Design Rules for Ionic Liquid Epoxy Curing Agents

Abstract Epoxy formulations containing a 20-member library of 1-methylimidazolium dicyanamide ionic liquids showed systematic N-substituent-dependent differences in thermal curing behavior. The library comprised alkyl, unsaturated, polar-functionalized, ether/silyl-containing, an...

Simultaneous Network Design With Restricted Link Usage

ABSTRACT Given a digraph with two terminal vertices and as well as a conservative cost function and several not necessarily disjoint color classes on its arc set, our goal is to find a minimum‐cost subset of the arcs such that its intersection with each color class contains an ‐...
