Identification of (20R)‐protopanaxadiol from Panax ginseng as a novel anti‐SARS‐CoV‐2 compound

open access: yesFEBS Open Bio, EarlyView.
We established a noninfectious BAC‐based SARS‐CoV‐2 replicon that enables antiviral screening under BSL‐2 conditions. Using this platform, we screened 373 food‐derived compounds and identified (20R)‐protopanaxadiol from Panax ginseng as a novel inhibitor of SARS‐CoV‐2 RNA replication, highlighting the value of safe replicon systems for antiviral ...

Modifications in the SIFT operator for effective SAR image matching [PDF]

open access: yes, 2010
With the increasing availability and rapidly improving spatial resolution of SAR images from latest and future satellites like TerraSAR-X and TanDEM-X, their applicability in remote sensing applications is set to be paramount.

A Wideband Wearable Antenna with AMC Ground Plane for WBAN Applications [PDF]

open access: yesRadioengineering, 2022
A flexible wearable antenna with wideband characteristics and having a conical radiation pattern which is suitable for ON body application is presented. To realize a compact antenna size, characteristic modal (CM) analysis is performed initially, and the

Adenosine triphosphate as a modulator of protein interactions and stability

open access: yesFEBS Open Bio, EarlyView.
ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

Digital Beamforming and MIMO SAR: Review and New Concepts [PDF]

open access: yes, 2012
Spaceborne Synthetic Aperture Radar (SAR) is a unique tool for large scale Earth observation, but the current generation of SAR sensors suffers from some fundamental limitations with regard to their imaging and mapping capabilities.

Neurologic Manifestations of Long COVID Affect Adult Females More Severely Than Males

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To characterize differences in neurologic manifestations of postacute sequelae of SARS‐CoV‐2 infection (Neuro‐PASC) between females and males. Methods Cross‐sectional study of the first consecutive 261 posthospitalization Neuro‐PASC (PNP) and 2068 nonhospitalized Neuro‐PASC (NNP) patients evaluated at the Neuro‐COVID clinic between ...

SAR moving target imaging using group sparsity [PDF]

open access: yes, 2013
SAR imaging of scenes containing moving targets results in defocusing in the reconstructed images if the SAR observation model used in imaging does not take the motion into account.

Numerical examinations of simplified spondylodesis models concerning energy absorption in magnetic resonance imaging

open access: yesCurrent Directions in Biomedical Engineering, 2016
Metallic implants in magnetic resonance imaging (MRI) are a potential safety risk since the energy absorption may increase temperature of the surrounding tissue. The temperature rise is highly dependent on implant size. Numerical examinations can be used

Learning a Dilated Residual Network for SAR Image Despeckling [PDF]

open access: yesRemote Sensing, 2017
In this paper, to break the limit of the traditional linear models for synthetic aperture radar (SAR) image despeckling, we propose a novel deep learning approach by learning a non-linear end-to-end mapping between the noisy and clean SAR images with a ...
