Γ-independent dominating graphs of paths and cycles [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST)
A set D of vertices in a graph G is an independent dominating set if D is a set of pairwise nonadjacent vertices of G such that every vertex of G not in D is adjacent to at least one vertex in D.

Microalgae growth in ultra-thin steady-state continuous photobioreactors: assessing self-shading effects

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
To disclose the net effect of light on microalgal growth in photobioreactors, self-shading and mixing-induced light–dark cycles must be minimized and discerned from the transient phenomena of acclimation.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Edge ideals and DG algebra resolutions

open access: yesLe Matematiche, 2015
Let R = S/I where S = k[T_1, . . . , T_n] and I is a homogeneous ideal in S. The acyclic closure R<Y> of k over R is a DG algebra resolution obtained by means of Tate’s process of adjoining variables to kill cycles.

On size multipartite Ramsey numbers for stars versus paths and cycles

open access: yesElectronic Journal of Graph Theory and Applications, 2017
Let $K_{l\times t}$ be a complete, balanced, multipartite graph consisting of $l$ partite sets and $t$ vertices in each partite set. For given two graphs $G_1$ and $G_2$, and integer $j\geq 2$, the size multipartite Ramsey number $m_j(G_1,G_2)$ is the ...

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.
