Cyclic Block Designs With Block Size 3
European Journal of Combinatorics, 1981 We prove that the necessary conditions for the existence of cyclic block designs with block size 3 are sufficient with two exceptions.

Exact bounds for (λ,n)–stable 0-1 matrices. [PDF]
Transactions on Combinatorics, 2020 Consider a v × v (0, 1) matrix A with exactly k ones in each row and each column. A is (λ, n)–stable, if it does not contain any λ × n submatrix with exactly one 0. If A is (λ, n)–stable, λ, n ≥ 2, then under suitable conditions on A, v ≥ k k(n−1)+(λ−2) .

Construction of Tm-type and Tm-assisted PBIB designs
Revstat Statistical Journal, 2022 Two-associate class triangular designs have been explored greatly but the Tm-type PBIB designs (m ≥ 3) largely remains unexplored. The paper is written with an objective to construct a new series of Tm-type PBIB designs and to derive some more series of

Statistical Methods to Support Difficult Diagnoses
Diagnostics, 2021 Far too often, one meets patients who went for years or even decades from doctor to doctor without obtaining a valid diagnosis. This brings pain to millions of patients and their families, not to speak of the enormous costs.

Journal of Mathematics, 2023 In this article, we adapt the edge-graceful graph labeling definition into block designs and define a block design V,B with V=v and B=b as block-graceful if there exists a bijection f:B⟶1,2,…,b such that the induced mapping f+:V⟶Zv given by f+x=∑x∈AA ...

Inhalation-modulated detection of olfactory BOLD responses in the human brain
Frontiers in Neuroimaging, 2023 IntroductionIn contrast to other sensory domains, detection of primary olfactory processes using functional magnetic resonance imaging has proven to be notably challenging with conventional block designs.

Construction of Some Circular Regular Graph Designs in Blocks of Size Four Using Cyclic Shifts
Journal of Statistical Theory and Applications (JSTA), 2020 Circular regular graph designs play an important role in the design of experiments where most of the balanced incomplete block designs require a large number of blocks.

A Statistical Model for the 2-Part Balanced Incomplete Block Design
UMYU Scientifica Journal, 2023 Multi-part Balanced Incomplete Block Designs combine many orthogonal balanced incomplete block designs in the same block. The design has been used to study cancer trials with medical centres as blocks.

Convex Cone Conditions on the Structure of Designs [PDF]
, 2003 Various known and original inequalities concerning the structure of combinatorial designs are established using polyhedral cones generated by incidence matrices. This work begins by giving definitions and elementary facts concerning t-designs.
