Quantum number projection at finite temperature via thermofield dynamics
, 2004 Applying the thermo field dynamics, we reformulate exact quantum number projection in the finite-temperature Hartree-Fock-Bogoliubov theory. Explicit formulae are derived for the simultaneous projection of particle number and angular momentum, in ...

ON PROJECTIONS IN PROJECTIVE SPACES
Demonstratio Mathematica, 1998 Die Verff. betonen, daß eine projektive Kollineation \(\varphi\) eines projektiven Raumes \(PG(V)\), \(V\) ein Vektorraum der Dimension \(\geq 2\), auch dadurch definiert werden kann, daß \(\varphi|_U\) für einen wenigstens 2-dimensionalen linearen Unterraum \(U\) eine solche ist.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Surveillance imaging aims to detect tumour relapse before symptoms develop, but it's unclear whether earlier detection of relapse leads to better outcomes in children and young people (CYP) with medulloblastoma and ependymoma. This systematic review aims to identify relevant literature to determine the efficacy of surveillance magnetic ...

Bounds on \"{U}bercrossing and Petal Numbers for Knots [PDF]
, 2013 An $n$-crossing is a point in the projection of a knot where $n$ strands cross so that each strand bisects the crossing. An \"ubercrossing projection has a single $n$-crossing and a petal projection has a single $n$-crossing such that there are no loops ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background We describe clinical and biologic characteristics of neuroblastoma in older children, adolescents, and young adults (OCAYA); describe survival outcomes in the post‐immunotherapy era; and identify if there is an age cut‐off that best discriminates outcomes.

Ideals of Projections According to σ-Algebras and Unbounded Measurements
Axioms, 2023 A theory of unbounded measures is constructed based on the quantum logics of orthogonal projections. As an analogue of the ring of sets, the projector ideal is proposed. Finite and maximal measures regarding the projector ideals are described.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Despite their increased risk for functional impairment resulting from cancer and its treatments, few adolescents and young adults (AYAs) with a hematological malignancy receive the recommended or therapeutic dose of exercise per week during inpatient hospitalizations.

Consolidation of the subjects of the Russian Federation as an element of economic development [PDF]
Экономика региона, 2011 The discussion on the optimality of the currently existing structure of the subjects of the Russian Federation is illustrating the contradictions that have been accumulated in the dominion form of government of our country in recent years. In this paper,

Cylindrical Algebraic Decomposition Using Local Projections
, 2014 We present an algorithm which computes a cylindrical algebraic decomposition of a semialgebraic set using projection sets computed for each cell separately.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background B‐acute lymphoblastic leukemia (B‐ALL) is the most common pediatric cancer, and while most children in high‐resource settings are cured, therapy carries risks for long‐term toxicities. Understanding parents’ concerns about these late effects is essential to guide anticipatory support and inform evolving therapeutic approaches ...
