Theoretical and Phenomenological Status of Neutrino Physics: A Brief Review by Surender Verma

“…The inclusion of new physics beyond the SM inevitably brings new parameters which are not constrained by the present experimental data on neutrino masses and mixing angles and, thus, are free parameters of the theory. We, also, discuss various theoretically motivated phenomenological approaches which can be used to reduce the number of free parameters and, thus, provide an excellent tool to understand the underlying physics of neutrino masses and mixings. …”

The K-Theoretic Formulation of D-Brane Aharonov-Bohm Phases by Aaron R. Warren

“…The topological calculation of Aharonov-Bohm phases associated with D-branes in the absence of a Neveu-Schwarz B-field is explored. The K-theoretic classification of Ramond-Ramond fields in Type II and Type I theories is used to produce formulae for the Aharonov-Bohm phase associated with a torsion flux. …”

An application of stress energy tensor to the vanishing theorem of differential forms by Kairen Cai

“…The author applies the stress energy of differential forms to study the vanishing theorems of the Liouville type. It is shown that for a large class of underlying manifolds such as the Euclidean n-space, the complex n-space, and the complex hyperbolic space form, if any vector bundle valued p-form with conservative stress energy tensor is of finite norm or slowly divergent norm, then the p-form vanishes. …”

A representation theorem for operators on a space of interval functions by J. A. Chatfield

“…All integrals used are of the subdivision-refinement type. The main theorem [Theorem 3] gives a representation of TH where H is a function from R×R to N such that H(p+,p+), H(p,p+), H(p−,p−), and H(p−,p) each exist for each p and T is a bounded linear operator on the space of all such functions H. …”

Study on Disease Mechanism and Theoretical Quantification Method of Tunnel Structure by Yu Liu, Chun-an Tang, Peng-yu Wang, Yong-ping Guan, Shu-hong Wang

“…In addition, based on the in-depth study of the main structural diseases of the tunnel, the extenics theory is used to extract, quantify and classify several indicators that can accurately reflect the health status of the structure, and then establish the corresponding matter-element model to determine the weight of each indicator and the tunnel structure. …”
