A novel protein tyrosine phosphatase expressed in lin(lo)CD34(hi)Sca(hi) hematopoietic progenitor cells.

Stem cells are capable of extensive self-renewal in the absence of differentiation. The maintenance of this undifferentiated state occurs despite the fact that this cell is exposed to a milieu that is rich in a variety of growth and differentiation factors. A unifying feature of such hematopoietic factors is that they mediate their effects through the phosphorylation of tyrosine residues by var...

Compact Lowpass Filter Design by using Triangle Shape DGS

Most communication system contains an RF front end which performs signal processing with RF filters. Micro strip filters are a low cost means of doing this. Micro strip filters play various roles in wireless or mobile communication systems. There is an increasing demand for newer microwave and millimetre-wave systems to meet the emerging telecommunication challenges with respect to size, perfor...

Bandwidth Analysis by Introducing Slot in Interdigital Band Pass Filter Using ANN

In this paper, a new method of bandwidth estimation using variation of slot length on interdigital band pass filter has been presented using artificial neural networks for desired frequency range between 1.7—2.5 GHz. Interdigital filter is multifinger periodic structure which offers compact filter design space. An ANN model has been developed and tested for estimating the cut off frequency of b...

Design of a Two Octave Gysel Power-Divider Using DGS and DMS

This paper proposes a two way L and S band Gysel power divider/combiner that uses line to ground resistors. Step by step methods to obtain a wide isolation and transmission bandwidth are presented. A design that uses five resistors is selected and optimized based on Quasi Newton method. Then the Defected Microstrip Structure (DMS) and Defected Ground Structure (DGS) is used to obtain better tra...
