Preventing wall deposition in duct flows: The role of particle number density and flow direction

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Particle deposition in wall‐bounded turbulent flows is a challenge in many industries, including pneumatic conveying, filtration, and related applications. When particles accumulate near boundaries, they reduce transport efficiency, alter near‐wall flow structures, and cause blockage.

Overcoming spectral limits of perovskite photodetectors for the infrared region

open access: yesInfoScience, EarlyView.
Infrared (IR) photodetectors are vital for modern optoelectronics, but traditional inorganic semiconductors face limitations in cost, processing, and bandgap tunability. This review provides a summary of advanced strategies to extend metal halide perovskites into the IR region, categorizing approaches into intrinsic material engineering, physical ...

Dignity's Dilemma: Categorical Objections to Autonomous Weapons and Their Pacifist Entailments

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT Dignity objections to autonomous weapon systems are prominent in contemporary military ethics, yet their theoretical foundations remain underexamined. This article reconstructs those foundations, showing what categorical dignity objections require to function as absolute prohibitions.

Stretch‐shortening cycle force–time and power–time waveform analysis indicates limitations of the contralateral limb benchmark in athletes with ACL injury

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Unilateral countermovement jump (CMJsingle) testing is commonly used after anterior cruciate ligament reconstruction (ACLR) to assess stretch‐shortening cycle (SSC) function and return‐to‐sport readiness. However, the impact of ACLR on contralateral limb SSC function is poorly understood, which may impact the utility of the ...

GIS-Based Throwshed Analysis for Conflict Archaeology

open access: yesJournal of Computer Applications in Archaeology
In conflict archaeology, KOCOA—an acronym for Key terrain, Observation and fields of fire, Concealment and cover, Obstacles and Avenues of approach—is a widely used methodology for battlefield terrain analysis.

Comparison of Amplitude‐ and Amplitude‐Frequency‐Modulated Pulses for Outer Volume Suppression in Cardiac MRI: Application to Myocardial T2$$ {T}_2 $$ Mapping

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate single‐ and dual‐band pulse modules for suppressing extra‐cardiac signal in cardiac MRI, and test their applicability for time‐efficient imaging with reduced FOV in myocardial T2$$ {T}_2 $$ mapping at 3 T. Methods Outer Volume Suppression (OVS) was implemented using two regional saturation slabs, along the phase‐encoding ...

Asymmetric transferability of trait–environment relationships between native and exotic plant species in Singaporean forests differing in land‐use history

open access: yesOikos, EarlyView.
Functional traits allow ecologists to synthesise general rules of community assembly. In joint species distribution modelling, traits are increasingly used to explain species–environment relationships, with the intention of being able to generalise predictions to other species in other systems.

Development of a Methodology for Estimation the Starting Moments of a Set of Light Screens’ Intersection with a Shot Cloud

open access: yesПриборы и методы измерений
When studying the process of moving a shot cloud in space, various devices can be used, for example, light screens. For such studies, it is advisable to have a simulation model of the set of optical sensor signals at the intersection of light screens ...
