This study aimed to investigate the electronic and structural characteristics of m-fluoroaniline (MFA) and m-iodoaniline (MIA). Density functional theory (DFT) and CAM-B3LYP/LanL2DZ methods were employed to determine various properties such as the ...

In the woods of M-theory [PDF]
We study BPS states which arise in compactifications of M-theory on Calabi-Yau manifolds. In particular, we are interested in the spectrum of the particles obtained by wrapping M2-brane on a two-cycle in the CY manifold X. We compute the Euler characteristics of the moduli space of genus zero curves which land in a holomorphic four-cycle $S \subset X$.

Case-Based Statistical Learning: A Non-Parametric Implementation With a Conditional-Error Rate SVM
Machine learning has been successfully applied to many areas of science and engineering. Some examples include time series prediction, optical character recognition, signal and image classification in biomedical applications for diagnosis and prognosis ...

M-Theory Model-Building and Proton Stability [PDF]
We study the problem of baryon stability in M theory, starting from realistic four-dimensional string models constructed using the free-fermion formulation of the weakly-coupled heterotic string.

After reviewing how M‐theory subsumes string theory, we report on some new and interesting developments, focusing on the “brane‐world”.

Orientifold points in M theory [PDF]
We identify the lift to M theory of the four types of orientifold points, and show that they involve a chiral fermion on an orbifold fixed circle. From this lift, we compute the number of normalizable ground states for the SO(N) and $Sp(N)$ supersymmetric quantum mechanics with sixteen supercharges.

We review our recent proposal for a background-independent formulation of a holographic theory of quantum gravity. The present paper incorporates the necessary background material on geometry of canonical quantum theory, holography and space–time thermodynamics, Matrix theory, as well as our specific proposal for a dynamical theory of geometric quantum

Inhomogeneous M-theory cosmologies [PDF]
We study a class of inhomogeneous and anisotropic G2 string cosmological models. In the case of separable G2 models we show that the governing equations reduce to a system of ordinary differential equations. We focus on a class of separable G2 M-theory cosmological models, and study their qualitative behavior (a class of models with time-reversed ...
