Multicast state scalability is among the critical issues which delay the deployment of IP multicast. In our previous work, we proposed a scheme, called aggregated multicast to reduce multicast state. The key idea is that multiple groups are forced to share a single delivery tree. We presented some initial results to show that multicast state can be reduced, sometimes at the expense of bandwidth...

The PEGASUS laboratory is a versatile radiation facility dedicated to the advancement of novel concepts in beam physics. The installation of a new LaB6 cathode will allow for both thermionic emission and photoinjection operation. The PEGASUS plane wave transformer injector has been conditioned to 20 MW of RF power. Recent operations show a 15 MeV dark current beam that will be used for beam rad...

OBJECTIVE The University of California at Los Angeles (UCLA) Scleroderma Clinical Trial Consortium GI Tract Instrument (UCLA SCTC GITI) was recently developed to measure gastrointestinal tract disease in systemic sclerosis (SSc). Our study assesses the internal consistency and validity of the instrument in a different population than was used in the original study. METHODS A sample of 113 con...

It is no exaggeration that stem cells are a hot topic in the international biomedical arena. In California we are particularly and actually aware of this fact. We started the new year on January 12 with a Stem Cell Technology Conference focusing on senescence. More than a year after California voters elected to give $3 billion in bonds to fund stem cell research, and with the measure stalled in...

BACKGROUND We aimed to verify a Korean version of the Abbreviated University of California, Los Angeles, Post-Traumatic Stress Disorder Reaction Index (Abb-UCLA-PTSD RI-Korean version) among Korean adolescents to assess post-traumatic stress in this population. METHODS We recruited 1,254 adolescents who completed the Abb-UCLA-PTSD RI-Korean version scale, the Child Report of Post-Traumatic Sy...

An inadequate fit at the abutment/implant interface can generate mechanical and biological problems. The laboratorial stages could induce misfit in such interface when the castable UCLA abutment type is used. The purpose of this study was to comparatively evaluate the performance of three prosthetic laboratories (Labs A, B and C) by vertical fit analysis of castable UCLA abutments on the castin...

BACKGROUND/AIM To investigate the effects of conservative therapy applied before arthroscopic subacromial decompression on the clinical outcome in patients with stage 2 shoulder impingement syndrome. MATERIALS AND METHODS Sixty-eight patients having stage 2 shoulder impingement syndrome and treated with arthroscopic subacromial decompression were included in the study. We divided these patien...
