Further Inequalities for the Numerical Radius of Hilbert Space Operators
S. Tafazoli, H. R. Moradi, S. Furuichi +1
In this article, we present some new inequalities for numerical radius of Hilbert space operators via convex functions. Our results generalize and improve earlier results by El-Had…
Einstein Rings in Holography
Koji Hashimoto, Shunichiro Kinoshita, Keiju Murata
Clarifying conditions for the existence of a gravitational picture for a given quantum field theory (QFT) is one of the fundamental problems in the AdS/CFT correspondence. We propo…
3D Reconstruction of Whole Stomach from Endoscope Video Using Structure-from-Motion
Aji Resindra Widya, Yusuke Monno, Kosuke Imahori +4
Gastric endoscopy is a common clinical practice that enables medical doctors to diagnose the stomach inside a body. In order to identify a gastric lesion's location such as early g…
Topology change from a monopole to a dipole in Berry's phase
Shinichi Deguchi, Kazuo Fujikawa
The smooth topology change of Berry's phase from a Dirac monopole-like configuration to a dipole configuration, when one approaches the monopole position in the parameter space, is…
A 3 mm Spectral Line Survey toward the Barred Spiral Galaxy NGC 3627
Yoshimasa Watanabe, Yuri Nishimura, Kazuo Sorai +3
We conduct spectral line survey observations in the 3 mm band toward a spiral arm, a bar-end, and a nuclear region of the nearby barred spiral galaxy NGC 3627 with the IRAM 30 m te…
description of collectivity for shell nuclei
A. Saxena, A. Kumar, V. Kumar +2
In the present work, we have reported shell model results for open shell nuclei Ne, Mg and Si isotopes with in -shell model space. We have performed calcula…
