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

Diagnostic Cytopathology, EarlyView.ABSTRACT Background Salivary gland fine‐needle aspirates (FNAs) with low‐grade oncocytic features are diagnostically challenging due to the substantial morphologic overlap between benign oncocytic tumors and their malignant mimickers. This study evaluates the diagnostic discriminators, performance, and risk of malignancy of these lesions using the ...

Carbon emission assessment of tunnel infrastructures: From construction to operation
Deep Underground Science and Engineering, EarlyView.This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Role of SoxE transcription factors in development and disease
Developmental Dynamics, EarlyView.Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.
