The Notch locus of Drosophila melanogaster is one of a small number of zygotically acting "neurogenic" genes involved in the correct segregation of neural from epidermal lineages during embryogenesis as well as in other postembryonic developmental events. We have generated antibody probes against three regions of the Notch protein to study the expression of Notch and begin a biochemical charact...

In this paper, two compact quad-channel and six-channel diplexer are designed and fabricated using defected microstrip structure (DMS). This structure is designed for the desired frequency based on the literature reviews. The proposed configuration is composed of a conventional T-junction divider with two pairs of open bended stubs and dual/tri-band filters. In designing dual band filters, a lo...

Suprascapular nerve entrapment syndrome (SNES) is a neuropathy caused by compression of the nerve along its course. The most common compression sites include the suprascapular notch and the spinoglenoid notch. The aim of this article was to review the anatomical factors influencing the occurrence of SNES in the light of the newest reports. Potential predisposing morphological factors include a ...

A low-cost coplanar waveguide fed compact ultrawideband (UWB) antenna with band rejection characteristics for wireless local area network (WLAN) is proposed. The notch band characteristic is achieved by etching half wavelength C-shaped annular ring slot in the radiating patch. By properly choosing the radius and position of the slot, the notch band can be adjusted and controlled. With an overal...

Microstrip Patch antenna is generally used in a number of antenna systems because of their low profile, light weight, low cost, compactness etc. Patch antenna is also used with Microwave IC’s and Monolithic Microwave IC’s because of its compatibility. Reconfigurable band notches in UWB antennas are dynamic research area. The advantage of the antenna with reconfigurable band notch is to efficien...

A simple and compact microstrip line -fed ultrawideband planar monopole antenna with single band-notch characteristics is presented. Wide impedance bandwidth is achieved by inserting two rectangular slots on both sides of the microstrip feed line on the ground plane. Band notching is achieved by embedding a half wavelength C shaped slot on the radiator. The antenna is investigated numerically a...

In order to place the purpose and results of this investigation in their proper perspective, it will be necessary to present a short summary of the existing information concerning the Notch locus. In Drosophila melanogaster this locus has yielded both dominant and recessive mutants. The dominant class of Notch mutants will be discussed first. Then some pertinent information concerning four rece...
