Robust Analysis of Fluxes in Genome-Scale Metabolic Pathways

open access: yesScientific Reports, 2017
Constraint-based optimization, such as flux balance analysis (FBA), has become a standard systems-biology computational method to study cellular metabolisms that are assumed to be in a steady state of optimal growth. The methods are based on optimization

A Global Poincaré inequality on Graphs via a Conical Curvature-Dimension Condition

open access: yesAnalysis and Geometry in Metric Spaces, 2018
We introduce and study the conical curvature-dimension condition, CCD(K, N), for finite graphs.We show that CCD(K, N) provides necessary and sufficient conditions for the underlying graph to satisfy a sharp global Poincaré inequality which in turn ...

Discovery of the spatial pattern of prickles on the stem of the rose and the mathematical model of the pattern [PDF]

open access: yes, 2019
Reproducible pattern is a key characteristic of organisms. Many developmental patterns are known that it is orchestrated by diffusion of the factors. Herein, we reported a novel patterning that seems to be controlled by diffusion factors. Although it looks like the prickles randomly emerge on the stem of rose, we deciphered patterns for the position of
