Quantitation of Vascular Morphology by Directed Graph Construction
IEEE Access, 2019 The quantitation of morphology information of X-ray angiography image has an important value in the diagnosis of coronary artery disease. This paper proposes an automatic morphology estimation method by using directed graph construction for X-ray ...

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

Unknown Vulnerability Risk Assessment Based on Directed Graph Models: A Survey
IEEE Access, 2019 Nowadays, vulnerability attacks occur frequently. Due to the information asymmetry between attackers and defenders, vulnerabilities can be divided into known and unknown.

Algorithms, 2020 In a previous paper we defined the black and white SAT problem which has exactly two solutions, where each variable is either true or false. We showed that black and white 2-SAT problems represent strongly connected directed graphs. We presented also the

Visualize online collocation dictionary with force-directed graph [PDF]
, 2012 For second-language learners, collocational knowledge is very important. Knowing collocational phrases allows learners to speak and write in their targeted language naturally and reduce dramatically side effect of their first language.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
FEBS Letters, EarlyView.Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Journal of Computer and System Sciences, 1971 Diverse graph structure models for concurrent processing systems have been suggested and used. The structures differ in generality and scope according to the properties one wishes to model and analyze. In this paper we solve a problem of maximal storage requirements for a simple flowchart model called the Marked Graph Model.

FEBS Letters, EarlyView.Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

How to Layer a Directed Acyclic Graph
, 2002 We consider the problem of partitioning a directed acyclic graph into layers such that all edges point unidirectionally. We perform an experimental analysis of some of the existing layering algorithms and then propose a new algorithm that is more ...
