The streamline-diffusion method for a convection–diffusion problem with a point source
Journal of Computational and Applied Mathematics, 2003 The authors study a singularly perturbed convection-diffusion problem with a point source. This problem is solved by applying the streamline-diffusion finite element method to a class of Shishkin-type meshes. This approach enables the authors to prove pointwise error estimates, as well as the existence of superconvergent points for the first derivative.

Research of method for non-point source pollution load
IOP Conference Series: Earth and Environmental Science, 2020 Abstract With the increasingly prominent problem of non-point source pollution in river basin water environment, it has attracted people’s attention and become a hot field of international research. This paper summarizes the digital model of non-point source pollution, briefly sketches the simulation analysis method of non-point source ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Open source virtual environments in computer forensics
, 2008 In this paper we discuss the potential role of virtual environments in the analysis phase of computer forensics investigations. We argue that commercial closed source computer forensics software has certain limitations, and we propose a method which may ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

POINT-NONPOINT SOURCE POLLUTION TRADING USING COLLECTIVE PERFORMANCE INCENTIVES [PDF]
Point-nonpoint trading markets must accommodate the problem of monitoring individual nonpoint source discharges (NPS). A permit trading market that allows the regulator to monitor noncompliance based on observable aggregate NPS pollution levels, through ...

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
