The recent CDF-II measurement of the mass W boson shows a significant tension with Standard Model (SM) expectation, even when averaged earlier measurements. can be explained in framework any beyond-SM dynamics that contributes substantially to oblique S and T parameters. As typical example such physics, we try explain Georgi-Machacek model keeps ρ=1 at tree-level, explore parameter space accomm...

Primary hepatic neuroendocrine tumors (PHNETs) are extremely rare neoplasms. Herein, we report a case of a 70-year-old man with a hepatic mass. The non-contrast computed tomography (CT) image showed a low-density mass, and dynamic CT images indicated the enhancement of the mass in the arterial phase and early washout in the late phase. F18- fluorodeoxyglucose (18F-FDG) positron emission tomogra...

This paper presents a novel, edge-based segmentation method for identifying the mass contour (boundary) for a suspicious mass region (Region of Interest (ROI)) in a mammogram. The method first applies a contrast stretching function to adjust the image contrast, then uses a filtering function to reduce image noise. Next, for each pixel in a ROI, the energy descriptor (one of the Haralick descrip...

The intensification of wet textile processes, such as cleaning and dyeing, by application of ultrasound is well known. In these processes, mass transfer in the interyarn and intrayarn pores of the textile is the basic physical phenomenon. The results of experiments on textile cleaning, based on basic principles of acoustics and cavitation, coupled with analysis of the surface and cross section ...

To clarify the clinical implication of preheparin serum lipoprotein lipase mass (preheparin LpL mass), we studied the relationships between preheparin LpL mass and serum lipids, including midband lipoproteins, which migrate between very low density lipoproteins and low density lipoproteins on polyacrylamide gel disc electrophoresis, in hyperlipidemias. And we also studied the changes of prehepa...

Using a relativistic transport model for the expansion stage of S+Au collisions at 200 GeV/nucleon, we show that the recently observed enhancement of low-mass dileptons by the CERES collaboration can be explained by the decrease of vector meson masses in hot and dense hadronic matter.

We calculate nuclear effect in Drell-Yan massive lepton-pair production in terms of parton multiple scattering in Quantum Chromodynamics (QCD). We present the nuclear modification to inclusive Drell-Yan cross section dσ/dQ2 in terms of multiparton correlation functions. By extracting the size of the correlation functions from measured Drell-Yan transverse momentum broadening in nuclear medium, ...
