An exact value for the path-chromatic index of a complete graph

Le Matematiche, 1989
We prove that the edge of Kn cannot be partitioned into less than (n-1)/t Pi+2-free subgraphs. We show that this inequality is sharp and characterize the edge partitions which attain it.

Combinatorial Diffusion Auction Design

CoRR
Diffusion auction design for combinatorial settings is a long-standing challenge. One difficulty is that we cannot directly extend the solutions for simpler settings to combinatorial settings (like extending the Vickrey auction to VCG in the traditional settings).

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Hybrid Key pre-distribution scheme for wireless sensor network based on combinatorial design [PDF]

Journal of Advances in Computer Engineering and Technology, 2015
Key distribution is an important problem in wireless sensor networks where sensor nodesare randomly scattered in adversarial environments.Due to the random deployment of sensors, a list of keys must be pre-distributed to each sensor node before ...

Combinatorial t-designs from special functions

, 2020
A special function is a function either of special form or with a special property. Special functions have interesting applications in coding theory and combinatorial t-designs.

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.

Mapping Based on Combinatorial Designs

, 1996
We present mapping methods which are derived from combinatorics of experimental designs. Experimental designs also known as combinatorial designs are a part of discrete mathematics, which can provide many useful structures and efficient tools for ...

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.
