Structure-guided affinity maturation of a novel human antibody targeting the SARS-CoV-2 nucleocapsid protein

open access: yesScientific Reports, 2022
The continuous mutation of SARS-CoV-2 has presented enormous challenges to global pandemic prevention and control. Recent studies have shown evidence that the genome sequence of SARS-CoV-2 nucleocapsid proteins is relatively conserved, and their ...

Countermeasures [PDF]

open access: yesExtended Abstracts of the 2019 CHI Conference on Human Factors in Computing Systems, 2019
Ubiquitous computing is leading to ubiquitous sensing. Sensor components such as motion, proximity, and biometric sensors are increasingly common features in everyday objects. However, the presence and full capabilities of these components are often not clear to users. Sensor-enhanced objects have the ability to perceive without being perceived.

A high‐precision frequency estimation algorithm based on multi‐segment signal fusion

open access: yesIET Radar, Sonar & Navigation, 2023
As the current multi‐segment signal fusion algorithms cannot meet the requirement of high‐precision frequency estimation at different signal‐to‐noise ratios (SNRs), an adaptive fusion algorithm is proposed in this paper.

Lung-Targeted Delivery of Cepharanthine by an Erythrocyte-Anchoring Strategy for the Treatment of Acute Lung Injury

open access: yesPharmaceutics, 2022
As one of the most frequent complications of critical illness, acute lung injury (ALI) carries a high risk of clinical morbidity and mortality. Cepharanthine (CPA) has significant anti-inflammatory activity, however, due to poor water solubility, low ...

Recovery efficiencies for Burkholderia thailandensis from various aerosol sampling media

open access: yesFrontiers in Cellular and Infection Microbiology, 2012
Burkholderia thailandensis is used in the laboratory as a surrogate of the more virulent B. pseudomallei. Since inhalation is believed to be a natural route of infection for B. pseudomallei, many animal studies with B. pseudomallei and B. thailandensis

Psoralen Inactivation of Viruses: A Process for the Safe Manipulation of Viral Antigen and Nucleic Acid

open access: yesViruses, 2015
High consequence human pathogenic viruses must be handled at biosafety level 2, 3 or 4 and must be rendered non-infectious before they can be utilized for molecular or immunological applications at lower biosafety levels.
