Impact of weirs in altering benthic macroinvertebrate assemblages and composition structure in the Luvuvhu River Catchment, South Africa

open access: yesFrontiers in Environmental Science
Stream flow weirs disrupt river flow regimes, physical conditions, and biological composition of rivers, posing significant threat to the river’s functionality, integrity, and sustainability.

Temporal clear-water scour evolution at rock weirs

open access: yesShui kexue jinzhan, 2022
Rock weirs are commonly used eco-friendly river training structures. However, water flow over rock weirs can cause local scour, resulting in structural failure.

Machine Learning‐Assisted Design and Performance Prediction of a Compact Dual‐Band Polarization‐Insensitive THz Metamaterial Absorber for Skin‐Cancer‐Related Refractive‐Index Sensing

open access: yesAdvanced Electronic Materials, EarlyView.
A compact QASRR‐based THz metamaterial absorber enables polarization‐insensitive dual‐band absorption and skin‐cancer‐related refractive‐index sensing through measurable resonance shifts. Field, surface‐current, and circuit analyses clarify the dual‐resonance mechanism, while StackNet‐assisted prediction accurately estimates the simulated absorption ...

On the Effect of Width of Weir in the Suppressed Weirs

open access: yesTransactions of the Japan Society of Mechanical Engineers, 1961
In order to see the effect of width of weir b, experiments are performed for b=0.2, 0.1, 0.05, 0.025, and 0.0125 m when D=0.2 m, and for b=0.025 m when D=0.1 m. According as the magnitude b decreases, the drop of hydraulic gradient (water surface) increases. Consequently, the coefficient of discharge deviates from that of c when b is large.

Streamlining Diagnosis of Bardet–Biedl Syndrome: New Diagnostic Algorithm With Updated Criteria

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Considerable advances have been made in our understanding of Bardet–Biedl syndrome (BBS), particularly in its core clinical features and molecular genetics, warranting an update to the existing diagnostic criteria framework. Using a rigorous, evidence‐based, and consensus‐driven process, a multidisciplinary group of international experts and ...

Strategies for inducing diabetes in laboratory animals: Advances from chemical, surgical, immunologic, dietary, and genetic approaches

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This review summarizes the principal experimental approaches used to induce diabetes in animal models. Strategies include chemical agents (streptozotocin, alloxan, dithizone, gold thioglucose), dietary interventions (high‐fat and high‐sugar diets), surgical methods (total or partial pancreatectomy), genetic models (db/db, ob/ob, Goto‐Kakizaki [GK ...

Analysis of energy expenditure and behavioral characteristics in different mouse strains under normal and disease conditions

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Mouse metabolic and behavioral phenotypes are tightly linked to strain, age and disease state, with distinct dysregulation in each disease model, underscoring the need for standardized preclinical experimental conditions. Abstract Background Metabolic and behavioral traits in mice exhibit substantial variability across strains, ages, and disease states,
