Intersections of S-branes with waves and monopoles

open access: yesNuclear Physics B, 2015
We construct intersections of S-branes with waves and Kaluza-Klein monopoles. There are several possible ways to add a monopole to an S-brane solution similar to p-branes. On the other hand, one may add a wave only to the transverse space of an S-brane unlike a p-brane where wave resides on its worldvolume. The metric function of the wave is a harmonic

Tracking an electronic wave packet in the vicinity of a conical intersection [PDF]

open access: yesThe Journal of Chemical Physics, 2017
This work treats the impact of vibrational coherence on the quantum efficiency of a dissipative electronic wave packet in the vicinity of a conical intersection by monitoring the time-dependent wave packet projection onto the tuning and the coupling mode.

On a characteristic problem for a loaded hyperbolic equation

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2019
The paper studies a loaded hyperbolic equation with one - dimensional wave equation in its main part. In the loaded components there are two points, which are distributed respectively along a pair of intersecting characteristics at a constant speed. For

Analysis of flow in complex terrain using multi-Doppler lidar retrievals [PDF]

open access: yesAtmospheric Measurement Techniques, 2020
Strategically placed Doppler lidars (DLs) offer insights into flow processes that are not observable with meteorological towers. For this study we use intersecting range height indicator (RHI) scans of scanning DLs to create four virtual towers.

Evaluation of fatigue damage in a pure copper with nonlinear three-wave interaction

open access: yesNihon Kikai Gakkai ronbunshu, 2016
We investigated nonlinear ultrasonic characterization, nonlinear three-wave interaction, of the pure copper during fatigue with EMAR (Electromagnetic Acoustic Resonance), which was the combination with ultrasonic resonance and non-contacting transducer ...

P.25 Radial-Digital Pulse Wave Velocity: A Non-Invasive Method for Assessing Stiffness of Peripheral Small Arteries

open access: yesArtery Research, 2020
Pulse wave velocity (PWV) has been used to evaluate arterial stiffness of large arteries. Here, we examine the feasibility of radial-digital PWV (RD-PWV) as a measure of stiffness of smaller arteries, and its response to changes in local mean arterial ...

Remark on modular weights in low-energy effective field theory from type II string theory

open access: yesJournal of High Energy Physics, 2023
We revisit the modular weights in type IIB magnetized D-brane models. The simple analysis of wave function shows that the four-dimensional matter fields have the modular weight -1/2, but it may shift as one in type IIA intersecting D-brane models.

Improving the accuracy and robustness of carotid-femoral pulse wave velocity measurement using a simplified tube-load model

open access: yesScientific Reports, 2022
Arterial stiffness, as measured by pulse wave velocity, for the early non-invasive screening of cardiovascular disease is becoming ever more widely used and is an independent prognostic indicator for a variety of pathologies including arteriosclerosis ...
