Internal Phase Separation in Synthetic DNA Condensates

open access: yesAdvanced Science, EarlyView.
The modular, programmable system of DNA nanostructures developed provides programmatic control over multiphase condensate behavior, enabling mapping onto a predictive Flory‐Huggins model. This combined experimental and theoretical framework will help address open questions in condensate biophysics and facilitate the rational design of functional ...

Rainbow Connection Number of Graphs with Diameter 3

open access: yesDiscussiones Mathematicae Graph Theory, 2017
A path in an edge-colored graph G is rainbow if no two edges of the path are colored the same. The rainbow connection number rc(G) of G is the smallest integer k for which there exists a k-edge-coloring of G such that every pair of distinct vertices of G

Distribution of the Number of Encryptions in Revocation Schemes for Stateless Receivers [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
We study the number of encryptions necessary to revoke a set of users in the complete subtree scheme (CST) and the subset-difference scheme (SD). These are well-known tree based broadcast encryption schemes.

Teaching Combinatorial Principles Using Relations through the Placemat Method

open access: yesMathematics, 2021
The presented paper is devoted to an innovative way of teaching mathematics, specifically the subject combinatorics in high schools. This is because combinatorics is closely connected with the beginnings of informatics and several other scientific ...

On the Combinatorics of Smoothing [PDF]

open access: yesJournal of Mathematical Sciences, 2016
Many invariants of knots rely upon smoothing the knot at its crossings. To compute them, it is necessary to know how to count the number of connected components the knot diagram is broken into after the smoothing. In this paper, it is shown how to use a modification of a theorem of Zulli together with a modification of the spectral theory of graphs to ...

Advanced single‐cell RNA sequencing in tumor immunology

open access: yesInterdisciplinary Medicine, EarlyView.
This review highlights the applications of advanced single‐cell RNA sequencing (scRNA‐seq) technologies in tumor immunology. It summarizes representative scRNA‐seq methods according to technical principles, with a focus on single‐cell T cell receptor sequencing. This review also discusses how scRNA‐seq is used to construct immune cell atlases of tumors,

Kaleidoscopic Edge-Coloring of Complete Graphs and r-Regular Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2019
For an r-regular graph G, we define an edge-coloring c with colors from {1, 2, . . . , k}, in such a way that any vertex of G is incident with at least one edge of each color. The multiset-color cm(v) of a vertex v is defined as the ordered tuple (a1, a2,

A combinatoric formula

open access: yesJournal of Mathematical Analysis and Applications, 1991
A combinatoric problem is considered concerning the number of ways of throwing \(k\) balls into an array of \(n\times m\) cells in such a way that each row and each column of the cells must contain at least one ball and that each cell can contain at most one ball, where \(k\), \(n\), \(m\) are natural numbers. Let \(^ kB\) denote a set \(B\) with \(k\)

Commuting Pairs in Quasigroups

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT A quasigroup is a pair (Q,∗) $(Q,\ast )$, where Q $Q$ is a nonempty set and ∗ $\ast $ is a binary operation on Q $Q$ such that for every (a,b)∈Q2 $(a,b)\in {Q}^{2}$, there exists a unique (x,y)∈Q2 $(x,y)\in {Q}^{2}$ such that a∗x=b=y∗a $a\ast x=b=y\ast a$. Let (Q,∗) $(Q,\ast )$ be a quasigroup. A pair (x,y)∈Q2 $(x,y)\in {Q}^{2}$ is a commuting
