spinal muscular atrophies (smas) are one of the more common autosomal recessive and single gene disorders. they are heterogeneous disorders, both in phenotypic and genotypic aspects. prevalence of these disorders are about 1 of every 6000 to 25000 live born babies in different ethnicities. in some chinese population prevalence of disease reported to be 1 in 50000. if it was true, carrier freque...

This study presents a full-duplex Radio-over-Fiber (RoF) system providing the users' wireless access with a bit rate of 10 Gbps over 40 GHz radio carrier. This system can be used in a centralized radio access network (C-RAN) architecture because we provide a fully analog front haul link between central station and base station. We can consider it as infrastructure between remote radio heads (RR...

– Recently, Orthogonal Frequency Division Multiplexing (OFDM), as a multi-carrier, and a single carrier transmission systems are used widely in the communications industrial systems. Each one of these two techniques has their own advantages and disadvantages. To maintain a high data rate, OFDM is preferred over the single-carrier transmission system due to several shortages like, complexity of ...

It is important to have the accuracy sorting plan for the save of postman work time and the fast delivery of the receipt mail. It’s also very important to plan the proper carrier sorting plan at the situation where the number of pocket of letter sorting machine [LSM] is less than the number of postal code or the number of carrier. This paper describes the method for the carrier sorting plan and...

—Under high dynamic and weak signal environment in the satellite Tracking, Telemetry and Command (TT&C) systems, the carrier acquisition and tracking can’t be easily achieved. In this paper, an improved two-stage high dynamic and weak signal carrier acquisition and tracking are presented for perfect carrier synchronization. The typical U.S. Jet Propulsion Laboratory (JPL) high dynamic carrier ...

OBJECTIVE To compare the cost-effectiveness of hepatitis B virus (HBV) control strategies combining universal vaccination with hepatitis B immunoglobulin (HBIG) treatment for neonates of carrier mothers. METHODS Drawing on Taiwan's experience, we developed a decision-analytic model to estimate the clinical and economic outcomes for 4 strategies: (1) strategy V-universal vaccination; (2) strat...

In this study, the rate equation analysis of a BH-laser diode was performed for output carrier density (No) using the zero-degree solution of the Volterra series. The carrier rate equation of the laser diode was analyzed in terms of input carrier density (Ni) and output carrier density modeling (Ni − No) , with respect to the DC current (Io) . The polynomial root, which is obtained from the zer...

this paper deals with the extraction of l-theanine containing aliquat 336 as a carrier and cyclohexane as solvent across bulk liquid membrane. the optimum operation condition are as follows: extraction time of 150 min, initial concentration of theanine in the feed phase is 1.8 g/l, the carrier concentration is 0.5 m, the ion of the receiving phase is 0.2 m nacl of na2hpo4-nah2po4 buffer solutio...

This paper presents a laser model for describing the effects of nonequilibrium carrier distributions. The approach is based on the coupled Maxwell-semiconductor-Bloch equations, with carrier–carrier and carrier–phonon collisions treated in the relaxation rate approximation. Using examples involving relaxation oscillation, current modulation, and optical injection, we demonstrate how the model c...

A molecular dynamics simulation of vapor phase nucleation has been performed with 40,000 Lennard-Jones particles for the target gas and 0-160,000 particles for the carrier gas. Three carrier gas models are adopted, including a soft-core model, a Lennard-Jones model, and a modified Lennard-Jones model in which the attractive interaction can be adjusted. The effect of the carrier-gas pressure is ...
