Safety Evaluation of an Aqueous Root and Leaf Extract of Ashwagandha (Withania somnifera)

open access: yesPhytotherapy Research, EarlyView.
Sensoril, an aqueous root and leaf extract of ashwagandha showed no evidence of mutagenicity in the in vitro Ames assay, was negative in the in vitro micronucleus, in vivo mammalian bone marrow chromosome aberration assays, and was well tolerated in the rat at up to 4000 mg/kg BW/day when administered orally for a period of 90 days. The data from these

Towards operational assimilation of surface‐sensitive microwave radiances over land at Environment and Climate Change Canada: Investigation of key factors using a 1D‐EnVar framework

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The study evaluates five factors affecting the assimilation of surface‐sensitive Advanced Microwave Sounding Unit‐A (AMSU‐A) radiances over land, including the simultaneous estimation of surface emissivity and the standard set of state variables, to improve numerical weather prediction (NWP) at Environment and Climate Change Canada (ECCC).

Stratospheric and tropospheric seasonality and its implications for observation requirements in numerical weather prediction

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Daily time series of zonal‐mean zonal wind (m·s−1) at 10 hPa and 60° N from 1950 to 2021 from the ERA5 reanalysis. This shows huge variability in some seasons and very little in others. We provide evidence that high‐level observations, radiosonde and satellite, are more important during the extended winter season with its very large variability ...

Biomimetic Multifinger Tactile Sensing and Contact‐Regulated Palpation for Autonomous Breast Tumor Localization

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Early detection of breast abnormalities remains challenging: manual palpation is subjective and operator‐dependent, while imaging modalities may miss small or subtle stiffness anomalies. This paper presents a biomimetic multifinger robotic palpation approach intended to support early breast‐cancer screening and follow‐up assessment as a proof ...
