A modified adaptive Kalman filter algorithm for the distributed underwater multi-target passive tracking system.

A modified adaptive Kalman filter (AKF) algorithm is proposed to make underwater multi-target tracking with uncertain measurement noise reliable. By utilizing the proposed AKF algorithm with three core points, including an adaptive fading factor, measurement noise covariance adjustment, and an adaptive weighting factor, the unknown measurement noise and state vector can be estimated with good accuracy and robustness. The practical trial data verify this algorithm, and it has proven superior to all traditional algorithms in this Letter based on the results that it reduces the estimated position RMSEs by at least 10.

Characteristics of viral ovarian tumor domain protease from two emerging orthonairoviruses and identification of Yezo virus human infections in northeastern China as early as 2012.

Emerging tick-borne orthonairovirus infections pose a growing global concern, with limited understanding of the viral ovarian tumor-like cysteine proteases (vOTUs) encoded by novel orthonairoviruses. These vOTUs, a group of deubiquinylases (DUBs), disrupt the innate immune response. Yezo virus (YEZV), a recently discovered pathogenic orthonairovirus, was first reported in Japan in 2021.

A Surrogate BSL2-compliant Infection Model Recapitulating Key Aspects of Human Marburg Virus Disease.

Marburg virus disease (MVD) is a severe infectious disease characterized by fever and profound hemorrhage caused by the Marburg virus (MARV), with a mortality rate reaching 90%, posing a significant threat to humans. MARV lies in its classification as a biosafety level four (BSL-4) pathogen, which demands stringent experimental conditions and substantial funding. Therefore, accessible and practical animal models are urgently needed to advance prophylactic and therapeutic strategies for MARV.

One-pot isothermal CRISPR/Dx system for specific and sensitive detection of microRNA.

MicroRNA (miRNA) is a promising biomarker for the early diagnosis of pancreatic cancer. To enable sensitive and reliable miRNA detection, we have developed a one-pot isothermal CRISPR/Dx detection system by combining rolling circle amplification (RCA) and CRISPR/Cas12a. RCA and CRISPR/Cas12a reactions are carried out in a single closed tube, bypassing the transferring step.

Exercise preconditioning and resveratrol reduce the susceptibility of rats with obstructive jaundice to endotoxin and alleviate lung injury.

Introduction: Endotoxemia is a common issue for patients with biliary obstruction. The lung is the most affected organ by endotoxins. Exercise training can alleviate lipopolysaccharide (LPS)-induced lung inflammation and resveratrol has biological effects similar to exercise.
