Packings and Coverings of Various Complete Digraphs with the Orientations of a 4-Cycle.
<p>There are four orientations of cycles on four vertices. Necessary and sufficient conditions are given for covering complete directed digraphs <em>D<sub>v</sub></em>, packing and covering complete bipartite digraphs, <em>D<sub>m,n</sub></em>, and packing and covering the complete digraph on …

Packings and Coverings of Complete Graphs with a Hole with the 4-Cycle with a Pendant Edge
… coverings of various complete graphs with the 4-cycle with a pendant edge. We consider both restricted and unrestricted coverings. Necessary and sufficient conditions are given for such structures for (1) complete graphs K<sub>v, </sub>(2) complete bipartite graphs K<sub>m,n</sub>, and (3) …

Cyclic, f-Cyclic, and Bicyclic Decompositions of the Complete Graph into the 4-Cycle with a Pendant Edge.
… the complete graph on <em>v</em> vertices into 4-cycles with a pendant edge. In part, we will consider decompositions which admit automorphisms consisting of:</p><p>(1) a single cycle of length <em>v</em>,</p><p>(2) <em>f</em> fixed points and a cycle of length <em>v</em> − <em>f</em>, …

On Induced Subgraphs, Degree Sequences, and Graph Structure
… if they form the vertex set of an alternating 4-cycle in G. Our definition is a variation of the notion of the P4-structure, a hypergraph which has been shown to have important ties to the various decompositions of a graph. We show that A4-structure has many properties analogous to those of …

Kelių optinių ciklų trukmės impulsų parametrinis stiprinimas infraraudonojoje srityje /
… of this thesis is to generate and amplify few cycle pulses in the infrared region. In this thesis, two approaches were introduced for few cycle pulse parametric amplification at 800 nm and 1.5 μm. First approach is dedicated for prospects for increasing average power of OPCPA via multi-beam …

Steiner triple systems and cycle structure
… contemplate using pure Mathematical techniques. Cycle structure is an area of Steiner triple systems which has been largely unexplored and was chosen for this thesis as it offers an opportunity to develop and expand knowledge by applying a mixture of computational and theoretical techniques. For …

The Collective Moment: Reading Time in the Greek Anthology
… of the anthological cemetery. Chapter 4 (‘Cycle’) examines Agathias’ anthology’s endeavour to replicate the natural diachrony of earlier anthologies using only newly-composed poetry. His work, set at once in an ancient pre-Christian past and in a late-antique Christian present, sees …

Targeted Differentiation of Primary Head and Neck Squamous Cell Carcinoma Cells
… irregularly enlarged cell morphology, cell 4 cycle arrest with downregulation of Ki67, and reduced cell viability, were observed. RNAseq identified myocyte-lineage differentiation with upregulation of markers of myofibril assembly, including TPM1, TAGLN, and ACTA1. Immunofluorescence staining …

Discomfort glare, light scatter, and scene structure
… (1963)). Each subject's visual threshold for a 4 cycle per degree spatial grating was measured under BCD and control conditions, and a comparison made to assess if light scatter effects from the glare source influenced threshold contrast, C<sub>th</sub>. <br></br><br></br> The results of the study …

Computational and Statistical Detection of High-Dimensional Latent Space Structure in Random Networks
… a sup-norm geometry over the torus, the signed 4-cycle count is strictly stronger than the signed triangle count and is, furthermore, optimal among low-degree tests. Our main technical contribution is a novel strategy for bounding Fourier coefficients of random geometric graphs mimicking the …
