We present the optical and X-ray study of the radioloud quasar 4C +74.26. The ASCA spectrum is rather complex with indications of a reflection component, a neutral iron line and a warm absorber. The underlying power law has a photon index of Γ = 2.03± 0.09. The soft X-ray flux in 1996 is nearly twice as high as that found in a ROSAT observation in 1993 without apparent spectral changes. The X-r...

We report on near-infrared and optical observations of the GRB 970616 error box and of the X-ray sources discovered by ASCA and ROSAT in the region. No optical transient was found either within the IPN band or in the X-ray error boxes, similarly to other bursts, and we suggest that either considerable intrinsic absorption was present (like GRB 970828) or that the optical transient displayed a v...

responded to a survey asking when they should break confidentiality and report student risk-taking behaviors to school administrators. Generally, counselors believed it to be more ethical to break confidentiality when the behaviors were directly observed (as opposed to reported by students) and when the behaviors occurred on school grounds during school hours. Results also suggest counselors we...

Received ; accepted – 2 – ABSTRACT Two ASCA observations were made of two ultra-luminous compact X-ray sources Source 2 showed a 0.5–10 keV luminosity of 6 × 10 39 ergs s −1 (assuming a distance of 4.0 Mpc), and a hard power-law spectrum of photon index ∼ 1.4. As already reported, Source 1 was ∼ 3 times brighter on that occasion, and exhibited a soft spectrum represented by a multi-color disk m...

The Seyfert 2 galaxy Mrk 1210 was found to exhibit a flat hard X-ray component by ASCA, although ASCA could not distinguish whether it is an absorbed direct component or a reflected one. We then observed Mrk 1210 with BeppoSAX, and found that the X-ray spectral properties are quite different from those of ASCA, as have been confirmed with XMM-Newton; the flux is significantly higher than that i...

We develop two N = 2 superfield formulations of free equations of motion for the joint model of all D = 4 massless higher-superspin fields in generating form. The explicit Osp(2|4) supersymmetry is achieved without exploiting the harmonic superspace, and with adding no auxiliary component fields to those of N = 1 superfields. The formulations are developed in two different Osp(2|4) homogeneous ...

Accurate simulation of turbulent flow with separation is an important but challenging problem. In this paper, a data-driven Reynolds-averaged turbulence modeling approach, field inversion and machine learning implemented to modify the Spalart–Allmaras model separately on three cases, namely, S809 airfoil, periodic hill GLC305 airfoil ice shape 944. Field based discrete adjoint method used quant...

Lack of effective therapeutics for pancreatic cancer at the present time underscores the dire need for safe and effective agents for the treatment of this malignancy. In the present study, we have evaluated the anticancer activity and the mechanism of action of pristimerin (PM), a quinonemethide triterpenoid, against MiaPaCa-2 and Panc-1 pancreatic ductal adenocarcinoma (PDA) cell lines. Treatm...

But these experiments [2] will not give us any information about the dependence or independence of the two factors, namely study habit and home environment. In such cases, we resort to Factorial ANOVA which not only helps us to study the effect of two or more factors but also gives information about their dependence or independence in the same experiment. There are many types of factorial desig...

Abstract Introduction Leadless right ventricular (RV) pacing has been recently proposed as alternative to conventional pacemakers (PM's). While RV with a PM is known cause deterioration of left (LV) and systolic function over time, the effects leadless PM's are currently under-explored. In this prospective randomized study, we hypothesized that effect time on both LV not inferior pacing. Method...
