In recent years there has been much pressure placed on system designers to verify their designs with computer simulations before committing to actual printed circuit board layouts and hardware. Simulating complex digital designs is extremely beneficial, and very often, the prototype phase can be eliminated entirely. The same is not true for most analog circuits. While simulation can give a grea...

The High Energy Stereoscopic System (H.E.S.S.) observatory has carried a deep survey of the Galactic plane, in course which existence significant number ($\sim$ 78) TeV $\gamma$-ray sources was confirmed, many remain unidentified. HESS J1828-099 is point-like (Gaussian stand. dev. $<$ 0.07$^{\circ}$) unidentified source among 17 confirmed H.E.S.S. Plane Survey (HGPS) catalog. This also unique b...

We present high resolution radio observations of the nuclear radio emission in a sample of eight radio galaxies having Megaparsec sizes, using the European VLBI network at 18 cm. At a resolution of 25 mas we detect all the giant radio galaxies from our sample. Among themDA 240 and 1331−099 were imaged for an extended period. These observations reveal a twin-jet structure for DA 240 and one-side...

Background: Clinical laboratories need to manage resources properly and scientifically to survive in today's highly competitive environment. In this context, scientific-economic principles should be considered to determine the profitability or loss of laboratories. Thus, in this study, the net profit of laboratory services was measured based on scientific-economic principles. &nbsp;&nbsp; Meth...

We present the results of a recent reverberation-mapping campaign undertaken to improve measurements of the radius of the broad line region and the central black hole mass of the quasar PG2130+099. Cross correlation of the 5100 Å continuum and Hβ emission-line light curves yields a time lag of 22.9 −4.3 days, corresponding to a central black hole mass MBH = (3.8 ± 1.5)×10M⊙. This value supports...

Polystyrene-silica core-shell composite particles are prepared by one-step emulsion polymerization with a nonionic initiator VA-086, solely stabilized by silica nanoparticles. The silica nanoparticles are successfully incorporated as the shell, likely due to the fact that the nanoparticles are thermodynamically favorable to adsorb and remain at the liquid-liquid interfaces during the emulsion p...

ESE 099 Undergraduate Research and/or Independent Study An opportunity for the student to become closely associated with a professor in (1) a research effort to develop research skills and technique and/or (2) to develop a program of independent in-depth study in a subject area in which the professor and student have a common interest. The challenge of the task undertaken must be consistent wit...

Antisera were raised against the NH(2)-terminus of the putative basal lateral membrane (BLM) receptor for 1,25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3); BLM-VDR]. In Western analyses of BLM proteins, antibody (Ab) 099 was monospecific for a 64.5-kDa band. A protein of 64.5 kDa was also labeled by the affinity ligand [(14)C]1, 25(OH)(2)D(3)-bromoacetate; label was diminished in the presence of exc...
