We present a detailed study of the galaxy cluster Abell 795 and its central Fanaroff-Riley Type 0 (FR0) radio galaxy. From an archival Chandra observation, we found dynamically disturbed environment with evidences for sloshing intracluster medium. argue that alone cannot explain compactness galaxy, as similar conditions are also around extended sources. identified pair putative X-ray cavities i...

نیمه ی دوم قرن هشتم هجری در تاریخ ایران ویژگی خاصی دارد که می توان از آن به عنوان عصر حکومت های ملوک الطوایفی نام برد. در سال 736 هـ . ق سلطان ابوسعید، آخرین ایلخان قدرتمند مغول درگذشت. مرگ وی فرصتی به دست داد تا مدعیان جدید قدرت که اغلب از سرداران مغول و کارگزاران دولت ایلخانی بودند. در گوشه و کنار کشور اعلام استقلال کنند. به این ترتیب حکومت های متعددی در سراسر ایران تشکیل شد. از جمله آل چوپان...

In this paper, we study backward stochastic Volterra integral equations introduced in Lin [ Stochastic Anal. Appl. 20 (2002) 165–183] and Yong Process. 116 (2006) 779–795] extend the existence, uniqueness or comparison results for general filtration as Papapantoleon et al. Electron. J. Probab. 23 (2018) EJP240] (not only Brownian-Poisson setting). We also consider L p -data explore time regular...

67 Ocean Drilling Program and Deep Sea Project sites were investigated to determine the relationship between temperature time for silica diagenesis. The selected cover a variety of settings where opal-A opal-CT transition zone lies in Cenozoic sediments. leads abrupt changes sediment petrophysics which are used identify diagenetic interval at study sites. This is thin ranging thickness from 10 ...

cell replacement therapy has provided the basis for future clinical applications to treat central nervous system injuries fallowing by car accidents. induced functional neurons are an option for replacing the lost neurons. the ability to monitor changes in membrane potential is a useful tool for studying neuronal function, but there are only limited options available at present. here, investiga...

We present a new method for determining the Galactic gravitational potential based on forward modeling of tidal stellar streams. We use this method to test the performance of smooth and static analytic potentials in representing realistic dark matter halos, which have substructure and are continually evolving by accretion. Our FAST-FORWARD method uses a Markov Chain Monte Carlo algorithm to com...

A rapid and sensitive method for determining protein concentrations using fluorescamine has been characterized for use in the analysis of intact lipoproteins. It was shown that there is no interference with the assay due to the presence of lipid-associated turbidity or primary amine content. The assay was shown to be sensitive to as little as 0.3 p g of lipoprotein and to yield similar results ...

A single frequency Ti:sapphire (Ti:S) laser with continuous frequency-tuning and low intensity noise is presented, in which an extra nonlinear (NL) loss crystal is placed inside the resonator instead of the traditional etalon locking system. When a NL crystal is inserted into a home-made Ti:S laser resonator, the single frequency laser of 1.27 W at 795 nm with a continuous frequency-tuning rang...
