Conditions for Singular Incidence Matrices [PDF]

open access: yes
Suppose one looks for a square integral matrixN, for which NN has a prescribed form.Then the Hasse-Minkowski invariants and the determinant of NN lead to necessary conditions for existence.The Bruck-Ryser-Chowla theorem gives a famous example of such ...

Modification of contact lenses via metal‐organic frameworks for glaucoma treatment

open access: yesAggregate, Volume 5, Issue 5, October 2024.
An optimized metal‐organic frameworks modified contact lenses (MIL‐101(Cr)@Lens) for prevention of blindness from glaucoma was developed by physical adsorption and aggregation of nanoparticles. MIL‐101(Cr)@Lens could effectively adopt brimonidine and release it in a sustained manner to achieve a 4.5‐fold better reduction of eye pressure than commercial

Combinatorial Designs with Two Singular Values I. Uniform Multiplicative Designs [PDF]

open access: yes
In this and a sequel paper [10] we study combinatorial designs whose incidence matrix has two distinct singular values.These generalize 2-(v, k, É) designs, and include partial geometric designs and uniform multiplicative designs.Here we study the latter,

A relation between BIB designs and chemical balance weighing designs

open access: yes
The paper gives certain new construction method for optimum chemical balance weighing designs. It utilizes a relation between the incidence matrices of a set of BIB designs and the design matrix of a chemical balance weighing design.BIB design optimum ...

Amicable matrices and orthogonal designs [PDF]

open access: yes, 2015
This thesis is mainly concerned with the orthogonal designs of Baumert-Hall array type, OD(4n;n,n,n,n) where n=2k, k is odd integer. For every odd prime power p^r, we construct an infinite class of amicable T-matrices of order n=p^r+1 in association ...
