BACKGROUND To clarify the significant clinicopathological and postdosimetric parameters to predict PSA bounce in patients who underwent low-dose-rate brachytherapy (LDR-brachytherapy) for prostate cancer. METHODS We studied 200 consecutive patients who received LDR-brachytherapy between July 2004 and November 2008. Of them, 137 patients did not receive neoadjuvant or adjuvant androgen depriva...

This paper presents the program BOUNCE for animating transients on transmission lines. BOUNCE is used for classroom demonstrations of fundamental concepts such as traveling wave, reflected wave, reflection from an unmatched load, and transmission through junctions and branches. BOUNCE provides a “laboratory” for students to use in verifying homework exercises solved with a lattice diagram. BOUN...

We review the recent status of big bounce genesis as a new possibility of using dark matter particles’ mass and interaction cross-section to test the existence of a bounce universe at the early stage of evolution in our currently-observed universe. To study the dark matter production and evolution inside the bounce universe, called big bounce genesis for short, we propose a model independent ap...

i ntroduction: apical debris extrusion (de) subsequent to root canal instrumentation, is one of the most important causes of endodontic flare-ups. the aim of this study was to compare the amount of de after root canal instrumentation using nickel-titanium (niti) hand files with step-back manual technique or installed on reciprocating handpiece. methods and materials: this study was conducted on...

We study a continuum model for simulating solid boundaries of a DPD fluid. A layer of frozen DPD particles is placed on the wall boundary and a continuum limit is taken. This produces effective dissipative and random forces. In addition, a reflection at the wall must be specified in order to confine the fluid. Three different wall reflection laws are studied and their effectiveness in producing...

The fast ion instability is considered for a distribution of ion bounce frequencies. Because of the spread in bounce frequencies, the instability initially grows exponentially with propagation distance. When the initial growth saturates, the instability grows exponentially with the square root of the propagation distance; the saturated growth equals that calculated when the spread in ion bounce...

The UK has had a commitment to loan guarantee schemes since 1981 when it introduced the Small Firms Loan Guarantee (SFLG) scheme address access debt finance issues for smaller firms. Over last 40 years, its support been unwavering, and in Covid-19 crisis, once again turned guarantees as means of supporting firms through crisis-induced slump trading activities. Of three core schemes, Bounce Back...
