Perfect Space–Time Block Codes [PDF]
, 2006 In this paper, we introduce the notion of perfect space–time block codes (STBCs). These codes have full-rate, full-diversity, nonvanishing constant minimum determinant for increasing spectral efficiency, uniform average transmitted energy per antenna and

Shape of Polymer Chains Confined in Spheres [PDF]
Polymer Journal, 1998 A self-avoiding polymer chain confined in a sphere is generated by Monte Carlo technique on a simple cubic lattice. The dependence of shape of polymer chain on concentration C of polymer solution is studied. The shape of polymer chain is denoted as 〈L12〉:〈L22〉:〈L32〉, where L1≤L2≤L3 are orthogonal components in the system of principal axes of gyration ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT In pediatric patients, T‐cell lymphoblastic lymphoma (T‐LBL) survival exceeds 80%. Relapse remains associated with limited curative options. Frontline treatment is largely extrapolated from T‐cell acute lymphoblastic leukemia (T‐ALL) treatment, reflecting the ongoing debate, whether both entities represent distinct diseases or variants within ...

Manifolds accepting codimension-one- sphere-shape decompositions
Topology and its Applications, 1985 This paper is concerned with the following question. Which connected closed m-manifolds can accept decompositions so that each element of the decomposition is shape equivalent to the (m-1)-sphere \(S^{m-1} ?\) The author shows that all such decompositions must be upper semicontinuous for \(m\geq 2\).

Faceted polymersomes: a sphere-to-polyhedron shape transformation
Chemical Science, 2019 We uncover how our polymersomes facet through a sphere-to-polyhedron shape transformation pathway that is driven by perylene aggregation confined within a topologically spherical polymersome shell.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background This study investigated how neighborhood‐level social determinants of health (SDOH), including redlining and neurological risk, interact to influence cognitive outcomes in children treated for brain tumors (CTBT). Methods A retrospective chart review of 161 CTBT aged 5–17 was conducted.

Вестник Российского экономического университета имени Г. В. Плеханова, 2017 The article shows the reasons for transforming university into a specific form of business as a result of altering the process of education into the process of organized and mass self-studying based on its computerization. This opportunity is realized by

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
