Dynamic response functions and helical gaps in interacting Rashba nanowires with and without magnetic fields [PDF]
, 2016 A partially gapped spectrum due to the application of a magnetic field is one of the main probes of Rashba spin-orbit coupling in nanowires. Such a "helical gap" manifests itself in the linear conductance, as well as in dynamic response functions such as

Journal of Intelligent Systems, 2015 On the basis of the combination of single-valued neutrosophic sets and hesitant fuzzy sets, this article proposes a single-valued neutrosophic hesitant fuzzy set (SVNHFS) as a further generalization of the concepts of fuzzy set, intuitionistic fuzzy set,

Self-adaptive GA, quantitative semantic similarity measures and ontology-based text clustering [PDF]
, 2008 As the common clustering algorithms use vector space model (VSM) to represent document, the conceptual relationships between related terms which do not co-occur literally are ignored.

˜The œinternational Arab journal of information technology, 2021 The goal of optimizing the best acceptable answer is according to the limitations and needs of the problem. For a problem, there are several different answers that are defined to compare them and select an optimal answer; a function is called a target ...

Precise numerical results for limit cycles in the quantum three-body problem [PDF]
, 2005 The study of the three-body problem with short-range attractive two-body forces has a rich history going back to the 1930's. Recent applications of effective field theory methods to atomic and nuclear physics have produced a much improved understanding ...

Momentum-space conformal blocks on the light cone
Journal of High Energy Physics, 2018 We study the momentum-space 4-point correlation function of identical scalar operators in conformal field theory. Working specifically with null momenta, we show that its imaginary part admits an expansion in conformal blocks.

Improvement of eigenfunction estimates on manifolds of nonpositive curvature [PDF]
, 2013 Let $(M,g)$ be a compact, boundaryless manifold of dimension $n$ with the property that either (i) $n=2$ and $(M,g)$ has no conjugate points, or (ii) the sectional curvatures of $(M,g)$ are nonpositive.

Representation formulas for cosine and sine functions of operators II
Aequationes Mathematicae, 1986 Using a Korovkin type approximation theorem the authors give representation formulas for strongly continuous cosine and sine families of linear operators on Banach spaces. [For part I see ibid. 29, 162-171 (1985; Zbl 0591.47028).]
