The circadian system alters thermoregulation depending on the time of day and feeding condition (2009)

Kei Nagashima, Ken Tokizawa, Yuki Uchida

The circadian rhythm of body temperature (Tb) is a well-known phenomenon. However, it is unknown how the circadian system affects thermoregulation. Food deprivation in mice induces a greater...

Kaluza-Klein bubble like structure and celestial sphere in inflationary universe (2004)

Shiromizu, Tetsuya, Tomizawa, Shinya, Uchida, Yuki, Mukohyama, Shinji

We consider five dimensional deSitter spacetimes with a deficit angle due to the presence of a closed 2-brane and identify one dimension as an extra dimension. From the four dimensional viewpoint we...

Twist of stationary black hole/ring in five dimensions (2004)

Tomizawa, Shinya, Uchida, Yuki, Shiromizu, Tetsuya

It is unlikely that uniqueness theorem holds for stationary black holes in higher dimensional spacetimes. However, we will examine the possibility that the higher multipole moments classify vacuum...

Stationary Einstein-Maxwell fields in arbitrary dimensions (2003)

Ida, Daisuke, Uchida, Yuki

The Einstein-Maxwell equations in D-dimensions admitting (D-3) commuting Killing vector fields have been investigated. The existence of the electric, magnetic and twist potentials have been proved....

The scalar perturbation of the higher-dimensional rotating black holes (2002)

Ida, Daisuke, Uchida, Yuki, Morisawa, Yoshiyuki

The massless scalar field in the higher-dimensional Kerr black hole (Myers- Perry solution with a single rotation axis) has been investigated. It has been shown that the field equation is separable...
