Development of a Droplet Digital PCR to Monitor SARS-CoV-2 Omicron Variant BA.2 in Wastewater Samples

open access: yesMicroorganisms, 2023
Wastewater-based surveillance can be used as a complementary method to other SARS-CoV-2 surveillance systems. It allows the emergence and spread of infections and SARS-CoV-2 variants to be monitored in time and place.

Transverse lattice [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2000
The transverse lattice approach to non-perturbative light-front hamiltonian QCD is described. Preliminary results on the pi-rho system are presented, at fixed DLCQ and Tamm-Dancoff cut-offs. A renormalised, approximately Lorentz covariant light-front hamiltonian is found to leading order of the colour-dielectric expansion, compatible with a massless ...

On k-transversals

open access: yesJournal of Combinatorial Theory, Series A, 1987
One of the main results of this paper is Theorem 3: If H is a family of infinite sets then H has a k-transversal if and only if it has a transversal.

Transverse transversals and homeomorphic transversals

open access: yesTopology, 1985
Let X, Y be disjoint \(C^ 1\) submanifolds of \({\mathbb{R}}^ n\) and let \(0\in Y\cap \bar X\). The pair (X,Y) is said to have transverse \(C^ k\) transversals of dimension s at 0 (1\(\leq k\leq \infty\), cod \(Y\leq s\leq n- 1)\) if \((t^ k_ s):\) for every \(C^ k\) submanifold S of dimension s transverse to Y at 0 there is some neighbourhood of 0 in

Using Volunteer Computing to Study Some Features of Diagonal Latin Squares

open access: yesOpen Engineering, 2017
In this research, the study concerns around several features of diagonal Latin squares (DLSs) of small order. Authors of the study suggest an algorithm for computing minimal and maximal numbers of transversals of DLSs.

Targeted High-Throughput Sequencing Enables the Detection of Single Nucleotide Variations in CRISPR/Cas9 Gene-Edited Organisms

open access: yesFoods, 2023
Similar to genetically modified organisms (GMOs) produced by classical genetic engineering, gene-edited (GE) organisms and their derived food/feed products commercialized on the European Union market fall within the scope of European Union Directive 2001/
