Context. Kepler-444 is one of the oldest planetary systems known thus far. Its peculiar configuration consisting five sub-Earth-sized planets orbiting companion to a binary stellar system makes its early history puzzling. Moreover, observations HI-Ly α variations raise many questions about potential presence escaping atmospheres today. Aims. We aim study orbital evolution Kepler-444-d and Keple...
The predominant biosynthetic route to vitamin B6 is catalyzed by a single enzyme. The synthase subunit of this enzyme, Pdx1, operates in concert with the glutaminase subunit, Pdx2, to catalyze the complex condensation of ribose 5-phosphate, glutamine and glyceraldehyde 3-phosphate to form pyridoxal 5¢-phosphate, the active form of vitamin B6. In previous studies it became clear that many if not...
PURPOSE To examine the prognostic value of cytokeratin-19 (CK-19) mRNA-positive circulating tumor cells (CTCs) in early-stage breast cancer patients focusing on clinically relevant subgroups based on estrogen receptor (ER) and HER2 expression. PATIENTS AND METHODS CK-19 mRNA-positive CTCs were detected by real-time reverse transcriptase polymerase chain reaction in the blood of 444 consecutiv...
-In this paper we study the effect of round trip propagation delay in performance measures of Wavelength Division Multiplexing (WDM) networks. Even though the impact of propagation delay is substantial in optical networks behavior, most of the studies ignore the effect of this object in throughput and delay evaluation. We assume a WDM Local Area Network (LAN) where the round trip propagation de...
In this paper we develop a performance model of the well-known Passive star coupled structure operating in a multichannel control system environment. The performance model is developed to reflect the impact of finite number of tunable receivers of the end stations in an asynchronous transmission access method. The Erlang-B formula for performance loss evaluation is used to analyze the model and...

Computer Game Architecture: A large computer game is a significant technical undertaking, involving a large number of interacting components. Of course, not all computer games require the same level of complexity. Different genres of games require different capabilities. The combination of components used for a simple casual 2-dimensional game like Tetris) is very different from a high-end 3-di...
