Previously we investigated the cosmic wiggly strings in (3+1)-dimensional Schwarzschild, ReissnerNordström and Kerr black holes. As an extension, the solutions in (3+1)-dimensional axially symmetric charged rotating black hole are investigated. The solution for the wiggly string exhibits open strings lying along the circular orbit in the equatorial plane outside horizon. © 2011 World Scientific Publishing Company. Source

We study classical motion of a string in (3+1)-dimensional spherically symmetric neutral and charged black holes. The solutions for the wiggly string exhibit open strings lying in the radial direction in the equatorial plane outside the horizon. © 2011 World Scientific Publishing Company. Source

Speed of exchange is important in communication using mobile phones. This study analyzes responses to a questionnaire survey of Japanese university students about replies to mobile text messages. Respondents were asked to indicate situations where a quick reply was desired and situations where a slow reply was acceptable. Free responses were classified broadly into seven groups such as "attributes of the other party," "one's own emotional state," "one's own situation," and "situation of the other party." Additionally, gender differences were seen in these free responses, with men more often referring to the attributes of the other party and their own situation and women more often referring to the content of the text messages. The results of the questions asking respondents to rank emotions by desired speed of response showed that there are individual differences in the relation between the type of emotion conveyed and the desired speed of reply (e.g.;a quick reply was desired when joy or apology was conveyed). These individual differences were then aggregated into three types by cluster analysis. © 2014 Elsevier Ltd. All rights reserved. Source

A mechanism using the position-dependent gauge coupling is proposed to localize nonAbelian gauge fields on domain walls in five-dimensional space-time. Low-energy effective theory posseses a massless vector field, and a mass gap. The four-dimensional gauge invariance is kept intact. We obtain perturbatively the four-dimensional Coulomb law for static sources on the domain wall. BPS domain wall solutions with the localization mechanism are explicitly constructed in the U(I) × U(1) supersymmetric gauge theory coupling to the non-Abelian gauge fields only through the cubic prepotential, which is consistent with the general principle of supersymmetry in five-dimensional space-time.
