The asymptotic existence of group divisible designs of large order with index one
, 2011 This paper gives the answer to a question of R.M. Wilson regarding the existence of group divisible designs of large order. Let k and u be positive integers such that 2⩽k⩽u. Then there exists an integer m0=m0(k,u) such that there exists a group divisible

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Strongly regular graphs and group divisible designs [PDF]
Pacific Journal of Mathematics, 1974 0. Introduction. In the present paper, we use the counting techniques of the author's earlier work [5] to prove the converse of a result of R.C. Bose and S.S. Shrikhande [3] on geometric and pseudo-geometric graphs (q + l,q+H). Section 1 is devoted to preliminaries on strongly regular graphs and group divisible designs. We also give a brief description

New constructions of divisible designs
, 1993 A construction is given for a (p2a(p+1),p2,p2a+1(p+1),p2a+1,p2a(p+1)) (p a prime) divisible difference set in the group H×Z2pa+1 where H is any abelian group of order p+1.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers
Molecular Oncology, EarlyView.The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Resolvable group divisible designs with block size 3
, 1989 Let v be a non negative integer, let λ be a positive integer, and let K and M be sets of positive integers. A group divisible design, denoted by GD[K, λ, M, v], is a triple (X, Г, β) where X is a set of points, Г = {G1, G2,…} is a partition of X, and β ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

More about Divisible Design Graphs [PDF]
, 2011 : Divisible design graphs (DDG for short) have been recently defined by Kharaghani, Meulenberg and the second author as a generalization of (v, k, λ)-graphs.

Further results on large sets of disjoint group-divisible designs
, 1992 This paper is a continuation of a recent paper by Chen and Stinson, where some recursive constructions for large sets of group-divisible design with block size 3 are presented. In this paper, we give two new recursive constructions.
