International Journal of Biological Macromolecules > 2017 > 103 > C > 525-532

Phospholipases A₂ inhibitors (PLIs) produced by venomous and non-venomous snakes play essential role in this resistance. These endogenous inhibitors may be classified by their fold in PLIα, PLIβ and PLIγ. Phospholipases A₂ (PLA₂s) develop myonecrosis in snake envenomation, a consequence that is not efficiently neutralized by antivenom treatment. This work aimed to identify and characterize two PLIs...

2016 IEEE Compound Semiconductor Integrated Circuit Symposium (CSICS)

We demonstrated an excellent output power (Pout) density performance using a novel InAlGaN/GaN-HEMT with an 80-nm gate for a high-power W-band amplifier. The developed HEMT showed basic reliability for commercial products. A unique double-layer silicon nitride (SiN) passivation film with oxidation resistance was adopted to suppress current collapse. The developed discrete InAlGaN/GaN-HEMT achieved...

We demonstrated an excellent output power (P_out) density performance using a novel InAlGaN/GaN-HEMT with an 80-nm gate for a W-band amplifier. To eliminate current collapse, a unique double-layer silicon nitride (SiN) passivation film with oxidation resistance was adopted. The developed discrete GaN-HEMT achieved a P_out density of 3.0 W/mm at 96 GHz, and we fabricated W-band amplifier MMIC using the...

2016 IEEE MTT-S International Microwave Symposium (IMS) > 1 - 4

2016 IEEE/MTT-S International Microwave Symposium - MTT 2016

A 33 to 41-GHz Low Noise Amplifier (LNA) with a 3-dB Noise Figure (NF) using 0.12-µm InAlGaN/GaN HEMT was developed. The LNA consists of a two-stage common-gate amplifier with current reuse topology in order to obtain a high gain with low power consumption. The developed LNA achieved 15-dB gain, and an input return loss of less than −10 dB. The measured NF was 3 dB, and the power consumption was 280...

Advances in Experimental Medicine and Biology > Adamantiades-Behçet’s Disease > Epidemiology > 77-79

Conclusion BD is a multisystemic inflammatory disorder with heterogeneous clinical features. The time of onset of oral aphthae was earlier than any other manifestation, and final incidence was 95% of our patients, and incidence was 56% in their thirties. The time of onset of several other clinical manifestations, including uveitis, skin lesions, genital ulcers and arthralgia was delayed, being 30...

Spontaneous Platelet Aggregation in Patients with Behçet’s Disease by Using Laser-Light Scattering Aggregometer

H. Nakano, H. Oka, T. Matsuda, S. Ooka, more

Advances in Experimental Medicine and Biology > Adamantiades-Behçet’s Disease > Cardiovascular Involvement > 437-441

Conclusion Most of patients with BD had spontaneous small-size aggregation in this system. Moreover, platelet clots (a large-size platelet aggregation) were only detected in patients with BD compared with normal individuals. These date suggest that BD may exhibit spontaneous hyper-coagulation of platelet function.

The National Synchrotron Light Source II is a third generation light source, which was constructed at Brookhaven National Laboratory. This project includes a highly-optimized 3 GeV electron storage ring, linac preinjector, and full-energy synchrotron injector. Budker Institute of Nuclear Physics built and delivered the booster for NSLS-II. The commissioning of the booster was successfully completed...

Contribution of alloantigens to hepatic ischemia/reperfusion injury: Roles of natural killer cells and innate immune recognition of nonself

Shoko Kimura, Kikumi S. Ozaki, Shinya Ueki, Matthew Zhang, more

Liver Transplantation > 22 > 1 > 80 - 90

Hepatic ischemia/reperfusion injury (IRI) remains a major clinical problem and involves the innate immune system's recognition of “nonself.” Considering the efficient nonself recognition by natural killer (NK) cells, we hypothesize in this study that hepatic IRI associated with liver transplantation (LT) could be augmented in allogeneic rather than in syngeneic (Syn) grafts due to alloantigen recognition...

Development of a novel scintillation-trigger detector for the MTV experiment using aluminum-metallized film tapes

S. Tanaka, S. Ozaki, Y. Sakamoto, R. Tanuma, more

Nuclear Inst. and Methods in Physics Research, A > 2014 > 752 > Complete > 47-53

A new type of a trigger-scintillation counter array designed for the MTV experiment at TRIUMF-ISAC has been developed, which uses aluminum-metallized film tape for wrapping to achieve the required assembling precision of ±0.5mm. The MTV experiment uses a cylindrical drift chamber (CDC) as the main electron-tracking detector. The barrel-type trigger counter is placed inside the CDC to generate a trigger...

2014 IEEE-NPSS Real Time Conference (RT)

T The MTV (Mott polarimetry for T-Violation) experiment at TRIUMF aims to search a large T-violation in nuclear beta decay outside of the Standard Model. The T-violating transverse polarization of the emitted electrons is measured as left-right scattering asymmetry in backward scattering event by a thin metal foil. The present experiment requires high statistical and systematic precision. In order...

Experimental verification of rate-dependent elastoplastic analogy friction model and its application to FE analysis

S. Ozaki, C. Ito, K. Hashiguchi

Tribology International > 2013 > 64 > Complete > 164-177

When two solid bodies in contact slide slowly past each other without lubrication, an intermittent vibration phenomenon might be observed. Such rate-dependent frictional behaviors are referred to as stick–slip motions, and such motions can impair the stability of machines and structures. The aim of this study is to propose a numerical approach for analyzing stick–slip motion; the approach is based...
