In this paper, we first prove a weak convergence theorem by Mann’s iteration for a commutative family of positively homogeneous nonexpansive mappings in a Banach space. Next, using the shrinking projection method defined by Takahashi, Takeuchi and Kubota, we prove a strong convergence theorem for such a family of the mappings. These results are new even if the mappings are linear and contractive.

We discuss the choice of gauge field basis in multiple–U(1) gauge theories. We find that there is a preferred basis, specified by the charge orthogonality condition, in which the U(1) gauge fields do not mix under one–loop renormalization group running.

Fluorescence based hydrogel glucose sensors are promising for improving continuous monitoring. In article number 2001286 by Jun Sawayama and Shoji Takeuchi, a responsive fluorescence PEG gel is developed; this has stable responses in vivo. The implantable device successfully traces blood concentrations diabetic model animal experiments. measures the concentration with an equivalent accuracy to ...
