A mass-type invariant for smooth metric measure spaces and its relation with the fractional Yamabe problem

Sergio Almaraz, Levi Lopes de Lima, Shaodong Wang

On an asymptotically Schwarzschild smooth metric measure space modelled on the Euclidean half-space, we define a mass-type quantity similar to the classical ADM mass in General Relativity and show its geometric invariance properties. Such quantity has a close relation with the fractional …

Development and validation of a novel latex particle-enhanced turbidimetric immunoassay for fecal calprotectin

Zhe Zhou, Yu Li, Feihu Zhang, Shaodong Wang et autres

BACKGROUND: Fecal calprotectin (FCP) is a crucial non-invasive biomarker for diagnosing and monitoring inflammatory bowel disease (IBD). However, the standard enzyme-linked immunosorbent assay (ELISA) is time-consuming and labor-intensive. This study aimed to develop a novel, independent latex particle-enhanced turbidimetric immunoassay (PETIA) suitable …

Discovery and functional characterization of endoglucanases from Coptotermes formosanus with enhanced cellulose hydrolysis via yeast surface display

Jingfang Sun, Chang Cao, Yushi Chen, Tian Shi et autres

ABSTRACT Microbial cellulose degradation offers a sustainable route to convert agricultural and forestry residues into value-added chemicals. Here, we report the discovery and functional characterization of eight novel endoglucanases (CTEG1 and CTEG3–CTEG9) from a Coptotermes formosanus cDNA library and heterologously expressed in …

An Enhanced SAR-Based ISW Detection Method Using YOLOv8 with an Anti-Interference Strategy and Repair Module and Its Applications

Lu Zhuo, Hui Du, Shaodong Wang, Jianping Wu et autres

The detection of internal solitary waves (ISWs) in the ocean using Synthetic Aperture Radar (SAR) images is important for the safety of marine engineering structures. Based on 4120 Sentinel SAR images obtained from 2014 to 2024, an ISW dataset covering the Andaman …

A positive mass theorem for non-smooth metrics on asymptotically flat manifolds with non-compact boundary

Sérgio de Moura Almaraz, Shaodong Wang

On a smooth asymptotically flat Riemannian manifold with non-compact boundary, we prove a positive mass theorem for metrics which are only continuous across a compact hypersurface. As an application, we obtain a positive mass theorem on manifolds with non-compact corners.

Experimental investigation of the load exerted by nonstationary internal solitary waves on a square column beneath an ice keel

Guanjing Wang, Shaodong Wang, Jianfang Fei, Pai Peng et autres

Abstract The safety of marine structures and underwater vehicles is seriously threatened by the nonstationary internal solitary waves (ISWs) beneath an ice keel. Laboratory experiments were conducted in a stratified fluid flume to examine the load characteristics of the square column that …

Theoretical analysis of internal solitary wave and its flow field in background flow

Shaodong Wang, Li Wang, Yanfeng Li, Wei Liu et autres

Abstract The influence of background flow on the vertical structure of concave internal solitary waves (ISW) in the continuous density stratification environment is studied by theoretical analysis method. The vertical inhomogeneous structures of ISWs in three cases of no background flow, linear …

Detection of oceanic internal waves in synthetic aperture radar images based on the canny operator

Zheyu Lu, Hui Du, Shaodong Wang, Pai Peng et autres

Abstract Internal solitary waves are a typical marine phenomenon, and the research on feature detection and parameter inversion of internal waves has important implications for marine engineering and military affairs. Internal waves in SAR images appear as distinct alternating bright and dark …

A priori estimates for negative constant scalar curvature conformal metrics with positive constant boundary mean curvature

Sérgio de Moura Almaraz, Shaodong Wang

Abstract On a compact Riemannian manifold with boundary, we study the set of conformal metrics of negative constant scalar curvature in the interior and positive constant mean curvature on the boundary. Working in the case of positive Yamabe conformal invariant, we prove …
