Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes
FEBS Open Bio, EarlyView.Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Evaluation of an acoustic Doppler technique for bed-load transport measurements in sand-bed Rivers
E3S Web of Conferences, 2018 The bottom tracking (BT) feature of the acoustic Doppler current profilers (ADCP) have emerged as a promising technique in evaluating the bed load. Strong statistical correlations are reported between the ADCP BT velocity and the transport rate obtained ...

Temporal variations of bed load transport rate and the grain size distribution of non-uniform size sediment during a constant flow rates [PDF]
MATEC Web of Conferences, 2018 Bedload transport rates at a point using both laboratory and field measurement vary with time, from almost zero to several folds of the mean rate. The need to carry out point measurements over a sufficiently long sampling period is very important to cover inconsistency in the transport rate during a short period of observation.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions
Advanced Engineering Materials, EarlyView.This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Influence of the sediment supply texture on morphological adjustments in gravel‐bed rivers
Water Resources Research, 2014 The role played by the texture of the sediment supply on channel bed adjustments in gravel‐bed rivers is poorly understood. To address this issue, an experimental campaign has been designed.

Comparison between Computations and Measurements of Bed Load Transport Rate in Nestos River, Greece
Procedia Engineering, 2016 AbstractIn the framework of diploma theses elaborated in the Division of Hydraulic Engineering, Department of Civil Engineering, Democritus University of Thrace, measurements of stream discharge and bed load transport rate were carried out at the outlet of the mountain part of Nestos River basin (northeastern Greece). In concrete terms, 68 measurements
