Cytokinesis in budding yeast is accomplished by the concerted action of actomyosin ring function and septum formation. The actomyosin ring is not essential for cell viability, but it is required for efficient cell division. Deletion of the actomyosin ring results in abnormal septum formation, and a delay in cytokinesis and cell separation. In contrast, septum formation is essential for cell via...

BACKGROUND Floating pubic symphysis (FPS) is a relatively rare injury caused by high-energy mechanisms. There are several fixation methods used to treat FPS, including external fixation, subcutaneous fixation, internal fixation, and percutaneous cannulated screw fixation. To choose the appropriate fixation, it is necessary to study the biomechanical performance of these different methods. The g...

Hybrid nanosuspensions were synthesised through ultrasonically dispersing ZrO2 or TiO2 nanoparticles into graphene oxide (GO) nanosheet solutions for water-based lubrication. The effect of contact pair roughness on the tribological behaviours ZrO2/GO and TiO2/GO hybrid investigated using a block-on-ring testing approach. With relatively smooth ring, use could reduce abrasive wear, hence improve...

Case report We report the case of a 55-year-old man with a history of oral cancer treated by surgery and radiotherapy who presented with recurrent syncope due to sinus node dysfunction and complete atrioventricular (AV) block after extensive neck and face reconstructive surgery. Surgeons had previously removed all pectoral muscles for facial reconstruction. During this reconstructive surgery, t...

the concept of fuzzy soft γ-ring is introduced; and some properties of fuzzy soft γ-rings are given. then the definitions of fuzzy soft γ-ideals are proposed and some of their theories are considered.

We have experimentally investigated single-port injection-triggered switching in a new class of semiconductor ring lasers with integrated gain, phase and passive waveguide sections as a building-block for all-optical signal processing such as high-speed analog-to-digital conversion. ©2009 Optical Society of America OCIS codes: (250.3140) Integrated optoelectronic circuits; (140.3560) Lasers, ring

EEcient and scalable parallel block algorithms for the LU factor-ization with partial pivoting, the Cholesky, and QR factorizations in a distributed memory multicomputer environment are presented. The distributed system is viewed as a ring of processors and the algorithms correspond to shared memory algorithms parallelized on block level (explicit parallelism). Performance of the algorithms are...

A highly programmable optical filter architecture is designed and a unit cell building block is fabricated in InP-InGaAsP with tunable inter-ring couplers. Simulated and measured bandpass filter responses for the 3-ring structure are presented. ©2010 Optical Society of America OCIS codes: 230.5750 Resonators, 250.5300 Photonic integrated circuits
