Numerical analysis of flow within a packed bed using computational fluid dynamics: Effects of fluid nature and regime [PDF]

Hemijska Industrija
This research conducts a computational fluid dynamics (CFD) analysis comparing laminar and k-epsilon turbulent models of fluid flow through a packed bed. For this, three types of fluids (water, water vapor and carbon dioxide) were examined. The CFD model

Tailoring Phonon‐Driven Responses in α‐MoO3 through Isotopic Enrichment

Advanced Materials, EarlyView.
ABSTRACT The implementation of polaritonic materials into nanoscale devices requires selective tuning of parameters to realize desired spectral or thermal responses. One robust material, α‐MoO3, an orthorhombic crystal boasting three distinct phonon dispersions, provides three polaritonic dispersions of hyperbolic phonon polaritons (HPhPs) across the ...

Impacts of Traditional Warm-Up and Post-Activation Potentiation on Muscle Endurance During the Back Squat: Response of Blood Lactate, Perceived Effort, and Time Under Tension

Journal of Functional Morphology and Kinesiology
Background: Warm-up strategies are essential for optimizing strength-training performance. Traditional warm-ups improve neuromuscular readiness, whereas post-activation potentiation (PAP) has been proposed to acutely enhance muscular output.

Personalized Network‐Guided Neuromodulation Enhances Human Working Memory

Advanced Science, EarlyView.
A personalized neuromodulation framework combining individualized functional brain network targeting with real‐time neural decoding is introduced. Using concurrent TMS–fMRI, participant‐specific stimulation targets and optimal frequencies are identified. Only optimal‐frequency stimulation improves working memory across sessions.

Cumulative Antigen Suppression Reduces Clonal Plasma Cell Evolution in Gaucher Disease

American Journal of Hematology, EarlyView.
ABSTRACT Chronic antigenic stimulation is implicated in the pathogenesis of monoclonal gammopathy and multiple myeloma, yet longitudinal human evidence linking sustained antigen exposure to modifiable clonal plasma cell evolution remains limited. Gaucher disease (GD), caused by biallelic GBA1 pathogenic variants, is characterized by accumulation of ...
