Transmissions that can change their velocity ratio are used in various mechanical devices to achieve a wide range of torques or speeds. For machines with transmissions, such as transportation vehicles, it is required to keep the output speed or the o

Organic anion transporter 1 (SLC22A6/OAT1) plays a key role in renal tubular excretion of endo- and exogenous anionic substances including drugs. Since the inhibition of OAT1 function by a concomitant drug may cause pharmacokinetic drug-drug interact

Monocarboxylate transporter 7 (MCT7) is an orphan transporter expressed in the liver, brain, and in several types of cancer cells. It has also been reported to be a survival factor in melanoma and breast cancers. However, this survival mechanism is n

We consider the decay rate of solutions to nonlinear Klein-Gordon systems with a critical type nonlinearity. We will specify the optimal decay rate for a specific class of Klein-Gordon systems containing the dissipative nonlinearites. It will turn ou

Silica-based polarization diversity circuit for QD-SOA operating in T-band was fabricated. By connecting polarization diversity circuits to QD-SOA chip, the polarization dependent gain of less than 0.8 dB and the optical gain of 3.2 dB were achieved.

We propose a compact polarization diversity optical circuit using silica waveguides and photonic crystal waveplates. By setting these circuits at the front and rear of the silicon optical devices, the polarization dependence of the silicon devices ca
