This paper presents a WiFi-aided magnetic matching (MM) algorithm for indoor pedestrian navigation with consumer portable devices. This algorithm reduces both the mismatching rate (i.e., the rate of matching to an incorrect point that is more than 20 m away from the true value) and computational load of MM by using WiFi positioning solutions to limit the MM search space. Walking tests with Sams...

L. K. Grover’s search algorithm in quantum computing gives an optimal, square-root speedup in the search for a single object in a large unsorted database. In this paper, we expound Grover’s algorithm in a Hilbert-space framework that isolates its geometrical essence, and we generalize it to the case where more than one object satisfies the search criterion. In memory of Daniel Walls 1. Departme...

We argue that the light particles in string theory obey an effective quantum mechanics modified by the inclusion of a quantum-gravitational friction term, induced by unavoidable couplings to unobserved massive string states in the space-time foam. This term is related to the W -symmetries that couple light particles to massive solitonic string states in black hole backgrounds, and has a formal ...

We present the X-ray spectral and temporal analysis of black hole transient Swift J1658.2--4242 observed by {\it AstroSat}. Three epochs data have been analysed using JeTCAF model to estimate mass accretion rates understand geometry flow. The best-fit disc rate ($\dot m_d$) varies between $0.90^{+0.02}_{-0.01}$ $1.09^{+0.04}_{-0.03}$ $\dot M_{\rm Edd}$ in these observations, while halo changes ...

Peroxisome proliferator-activated receptors (PPARs) are involved in the regulation of lipid and glucose metabolism. PPARgamma agonists improve insulin sensitivity and hyperglycemia and are effective in treating type 2 diabetes mellitus (T2DM), whereas PPARalpha agonists are used to treat dyslipidemia and atherosclerosis. The goal here was to examine the efficacy of a selective PPARalpha agonist...
