Objective(s): NOTCH signaling pathway is well known for its role in cell fate, cell survival, cell differentiation, and apoptosis. Some of the NOTCH signaling genes are critical for endometrial function and implantation in animals and appear to play a similar role in humans. The purpose of the current study was to investigate the potential roles of some main components of the NOTCH family in hu...

This study presents a novel miniaturized dual-band coupled-line impedance transformer. This dual-band matching technique uses the characteristics of coupled-line and dual-band stubs to realize matching arbitrary complex impedance to arbitrary complex impedance at two arbitrary uncorrelated frequencies. Especially, it satisfies the demand of dual-band matching at two relatively closed operating ...

Notch signaling is known to control early pancreatic differentiation through Ngn3 repression. In later stages, downstream of Notch, the Presenilins are still required to maintain the endocrine fate allocation. Amongst their multiple targets, it remains unclear which one actually controls the maintenance of the fate of the early islets. Conditional deletions of the Notch effector RBP-Jκ with lin...

This paper presents design of dual-band bandpass filter by integrating conventional quarter-wavelength short circuit stubs with U-shaped defected microstrip structure notch filter. Based on the parametric analysis, it is found that high attenuation level can be achieved using two separated specific distance. The designed simulated advanced system and fabricated based Roger 4350B. simulation res...

This paper introduces a novel approach to create notch band filters in the front-end of ultra-wideband (UWB) communication systems based on electromagnetic bandgap (EBG) structures. The concept presented here can be implemented in any structure that has a microstrip in its configuration. The EBG structure is first analyzed using a full wave electromagnetic solver and then optimized to work at W...

In this letter, a design of Compact Ultra-Wideband (UWB) bandpass filter with a switchable notch band for WLAN (5.3-5.9GHz) interference rejection is proposed. As 5.3-5.9GHz wireless local area network (WLAN) is existed in UWB spectrum range (3.1 -10.6GHz) and may interfere with UWB system operation. The UWB bandpass filter is implemented using a basic multiple mode resonator (MMR) structure fe...

in this work we deal with the question: how can one improve the approximation level for some nonlinear integral equations? good candidates for this aim are semi orthogonal b-spline scaling functions and their duals. although there are different works in this area, only b-spline of degree at most 2 are used for this approximation. here we compute b-spline scaling functions of degree 4 and their ...

This paper investigates an H-fractal wideband microstrip filter with multi-passbands and a tuned notch band for wireless communication frequencies. The four different filter configurations explored are: symmetric with zero offset, symmetric with nonzero offset, asymmetric with zero offset, and asymmetric with nonzero offset. The effect of H-fractal iterations, fractal scaling parameters, and st...

Recently, wireless-PAN systems using a UWB technique are considered. Antennas such as a planar trapezoidal monopole or dipole antenna for a UWB was developed.[1],[2] Since a 5 GHz band is allocated for wireless LAN service such as an IEEE802.11a, a UWB antenna should have a band notch to avoid an interference between two systems. To fulfil this requirement, several UWB antennas having a band no...

The first Doppler spectra ever acquired by an atmospheric radar at 200 GHz (G-band) are presented. observations were taken during a light precipitation event in May (rain rates <2 mm hr−1) Chilbolton Observatory, UK, with coincident Ka-band and W-band measurements. collected rain agree Mie theory predictions: G-band they show significant reductions the spectral power return—as compared to theor...
