Study of the Top-quark Pair Production in Association with a Bottom-quark Pair from Fast Simulations at the LHC
A large number of top quarks will be produced at the Large Hadron Collider
(LHC) for Run II period. This will allow us to measure the rare processes from
the top sector in great details. We present the study of the top-quark pair
production in association with a bottom-quark pair (ttbb) from fast simulations
for the Compact Muon Solenoid (CMS) experiment. The differential distributions
of ttbb are compared with the top-quark pair production with two additional
jets (ttjj) and with the production in association with the Higgs (ttH), where
the Higgs decays to a bottom-quark pair. The significances of ttbb process in
the dileptonic and semileptonic decay mode are calculated with the data
corresponding to an integrated luminosity of 10 fb-1, which is foreseen to be
collected in the early Run II period. This study will be an important input in
searching for new physics beyond the standard model as well as in searching for
ttH process where the Yukawa coupling with the top quark can be directly
measured.Comment: 12 pages, 12 figure
Natural History of Invasive Papillary Breast Carcinoma Followed for 10 Years: A Case Report and Literature Review
Diachronic research on untreated breast cancer completely depends on past medical records when no more recent, advanced methods are available. Herein, we report a case of invasive papillary breast carcinoma followed for 10 years in a 59-year-old woman who refused any treatment. The diagnosis was based on core needle biopsies. At the patient’s first visit in July 2006, the tumor measured 10.4 × 7.2 × 3.5 cm. It was staged as IIIB (T4bN1). In May 2016, the tumor was staged as IIIC (T4bN3a). In the past 10 years, the tumor has increased to 12.1 × 9.0 × 4.2 cm. However, a whole-body bone scan and 18F-FDG PET/CT showed no evidence of distant metastasis. Immunohistochemistry results, corresponding to biopsies taken at subsequent examinations, have remained unaltered since 2006. The tumor was estrogen/progesterone receptor-positive and C-erbB2 expression was not detected. The Ki-67 labeling index was around 10%
Investigation of the transverse beam dynamics in the thermal wave model with a functional method
We investigated the transverse beam dynamics in a thermal wave model by using
a functional method. It can describe the beam optical elements separately with
a kernel for a component. The method can be applied to general quadrupole
magnets beyond a thin lens approximation as well as drift spaces. We found that
the model can successfully describe the PARMILA simulation result through an
FODO lattice structure for the Gaussian input beam without space charge
effects.Comment: 12 pages, 6 figure
Delayed rupture of a pseudoaneurysm in the brachial artery of a burn reconstruction patient
A brachial artery pseudoaneurysm is a rare but serious condition that can be limb threatening. A number of reports have found that it may be the result of damage to the blood vessels around the brachial artery, either directly or indirectly, due to trauma or systemic diseases. We present our experience of delayed pseudoaneurysm rupture of the brachial artery in a rehabilitation patient with burns of the upper extremity who underwent fasciotomy and musculocutaneous flap coverage. We also provide a review of the brachial artery pseudoaneurysm
Mutagenic activity of river water from a river near textile industrial complex in Korea
The mutagenic activity of XAD-2 adsorbates and water extracts recovered from nine locations of the Kumho River was tested on S. typhimurium TA98 strain to identify the source of the mutagenicity. A sampling site, receiving effluents from the textile industrial complex located in Daegu City, showed extraordinarily high mutagenic activity, especially in the presence of S9 mixture, at all sampling time in both XAD-2 adsorbates and dichloromethane extracts. This indicated the existence of the frame-shift mutagens in the Kumho River, same type of mutagens detected in previous studies by other researchers in the Nakdong River into which the Kumho River discharges. The fractionation study showed that the mutagenic chemicals in the river water are mid-polar. Furthermore, mean tail length obtained by single cell gel electrophoresis assay (Comet assay) showed consistent dose-dependent DNA damage, indicating that the chemicals in the river water not only act as frame-shift mutagens but also break human lymphocytes DNA strain. Chemical identification of the mutagens should be require
