We do that by imposing on V relations coming from the braid band moves. These moves reflect isotopy in S1×S2 and they are similar to the second Kirby move.

The situation is worsened by the ongoing insurgency and terrorist activities in the area.&#x0D; AIM: The aim of this paper is to present the research findings from a cohort study aimed at the analysis of the estimation of the survivorship time of the real data of cancer patients in the North-eastern part of Nigeria and to

Abstract BACKGROUND: Primary Cutaneous Gamma-Delta T-Cell Lymphoma (PCGDTCL) is a rare subtype of cutaneous T-cell lymphoma (CTCL) that, despite comprising &amp;lt;1% of cutaneous lymphomas, has gained recognition in recent years as an entity separate from other rare CTCLs. (LeukemiaPMID 35732829) A 5 year survival of 11% demonstrates a low response to current available therapies. (BloodPMID 30635287, Clin Hematol Int.PMID 35950208) Due to lack of consistency in behavior between CTCLs, there exists a need for studies of demographic, clinical, and survival disparities, including between Hispani

However, some patients cannot afford these costly treatment options, especially in countries where reimbursement coverage is partial/absent.

The level of agricultural culture directly depends on the degree of mechanization of small farms. The purpose of the work is to improve the design of a small-sized potato harvester while increasing the efficiency of its ploughshare. A new design of a vibrating ploughshare in the design of a small-sized potato digger is proposed, which differs from typical designs in that the crank is made in the form of a disk, in which a groove is made in

In this study the topology optimization approach, a type of finite element analysis method (FEA), to reduce the material used in manufacturing was adopted. Out of these optimization methods, the mass optimization technique was deemed suitable. Mass optimization eliminates the parts that don't affect a bracket’s overall strength while under load, resulting in weight reduction and material savings. Two shelf brackets were designed to test this theory and were subjected to mass optimization. A static structural analysis of this optimized model was carried out to confirm the optimization findings.

Abstract We study pre-Lie pairs, by which we mean a pair of a homotopy Lie algebra and a pre-Lie algebra with a compatible pre-Lie action. Such pairs provide a wealth of algebraic structure, which in particular can be used to analyze the homotopy Lie part of the pair. Our main application and the main motivation for this development are the dg Lie algebras of hairy graphs computing the rational homotopy groups of the mapping spaces of the little disks operads. We show that twisting with certain Maurer–Cartan elements trivializes their Lie algebra structure. The result can be used to understand
