PURPOSE: The quality of a prostate brachytherapy implant depends on the accurate placement of sources. This study quantifies the misplacement of iodine-125 sources from the intended location using intra-operative ultrasound images. METHOD AND MATERIALS Iodine-125 sources were manually identified in the post-implant ultrasound images and compared to the pre-operative plan. Due to the subjective ...

PURPOSE To investigate the feasibility of and challenges yet to be addressed to measure dose from low energy (effective energy <50 keV) brachytherapy sources (Pd-103, Cs-131, and I-125) using polyurethane based 3D dosimeters with optical CT. METHODS The authors' evaluation used the following sources: models 200 (Pd-103), CS-1 Rev2 (Cs-131), and 6711 (I-125). The authors used the Monte Carlo r...

There are many methods for modeling species distribution in the landscape. In this chapter, the authors elaborate on the concepts of species modeling and present three popular techniques to generate species distribution: cartographic overlay, logistic multiple regression and maximum entropy (MAXENT). The cartographic overlay method is relevant to generate a habitat suitability index. Logistic m...

BACKGROUND Elevated beta-HCG serum levels are usually an indication of pregnancy or pregnancy-related disorders, but beta-HCG can also be elevated in testis and germ cell tumors. HCG expression by osteosarcoma is a rare phenomenon, with a few documented cases. CA-125 is commonly used to monitor disease progression and treatment response in ovarian cancer. CA-125 expression in patients with oste...

Aim: To study the prevalence of pathogenic coagulase positive, methicillin-resistant Staphylococcus aureus (MRSA) in poultry meat and its products. Materials and Methods: A total of 125 poultry samples were collected during 2012 in Qena governorate for presence of pathogenic coagulase positive, methicillin-resistant staphylococcus aureus (MRSA). Samples were taken from freshly slaughtered whole...

PURPOSE To compare the implant quality and clinical outcomes for patients treated with low and intermediate strength (125)I seeds in prostate brachytherapy implants. METHODS AND MATERIALS This retrospective review included 390 consecutive patients treated with prostate brachytherapy from 1999 to 2006. The first 142 patients were implanted with source strengths lower than 0.415U (0.327mCi), wi...

A broadband source of polarization entangled photons based on type-II spontaneous parametric down conversion from a chirped PPKTP crystal is presented. With numerical simulation and experimental evaluation, we report a source of broadband polarization entangled states with a bandwidth of approximately 125 nm for use in quantum interferometry. The technique has the potential to become a basis fo...

TTC’2015 is the 8th Transformation Tool Contest for users and developers of transformation tools. In this paper, we present the use of Spoon, an open-source library to transform and analyze Java source code for the code refactoring track of TTC’2015. We use Spoon to implement pull-up-method and create super-class refactorings. The implementation uses an unmodified revision of Spoon and is done ...
