The FCC; Federal Communication Commission, has assigned the frequency band for Ultra Wideband from 3.1 GHz to 10.6 GHz [13] . Meanwhile, few other signal spectrums such as, WLAN (5.15 to 5.825 GHz) and WiMAX (5.25 - 5.85 GHz) are making some interference within this range [14] . For this reason, the overall performance of UWB systems degrades in terms of bit error rate and creating pulse distortions [15] . Thus, it becomes mandatory to design UWB antennas with band notched characteristics in above mentioned frequency bands to ensure robust and interference free UWB antenna.

A perfectly designed ultra-wideband antenna can optimize hundreds of tasks in the field of medical services and entertainment, especially, when equipped in a wearable lightweight device. A miniaturized wearable electronic device with a UWB technology can serve the requirements of extremely high data transmission rate with a limited range, can connect all devices that a person caries & cooperate them with one another. To avoid interferences with other existing networks and serve the purpose flawlessly a band notch is also mandatory. This research work has taken the inspiration from all those matters by creating a new, innovative, and effective design.

In this paper, a small printed band notched UWB antenna is proposed. The band notch has been achieved by etching multiple slots on the patch. Simulations were done on CST Microwave Studio electromagnetic simulator. The proposed antenna was studied in close proximity to the human body simulation model for on-body communications.

The entire return loss curve was slightly left shifted. However, the notched frequency band remains perfect. On the on-body simulation s11 curve, several bands on 3.2 to 3.8 GHz and 7 to 10.5 GHz shows better return loss response.

Comparison between the radiation patterns for free space and on-body test of the proposed antenna was simulated on 3.5 GHz, 5.7 GHz (a frequency inside the notched band), 8 GHz, & 9 GHz on both XY and XZ planes and Figure 8, Figure 9, Figure 10 & Figure 11 show their simulated patterns respectively.

For On-Body simulation, the antenna was placed in front of the human body three layer model keeping 4 mm of vacant space. The on-body gain of the proposed UWB antenna shows some differences with the free space simulation as expected. Table 2 shows the comparison of gains on four different frequencies (including a sample frequency of 5.7 GHz inside the notched limit) between free space and On-body simulation.

From the data of Table 2 and Table 3, it is clearly visible that 5.7 GHz displays a poor result in terms of both gain and efficiency, which indicate the effectiveness of the band notch. In addition, the on-body test results are very much stable and similar to the free space on greater frequencies.

In this paper, a small printed compact UWB band-notched antenna was proposed and its free space and on-body performances were investigated. The antenna was perfectly band notched to avoid interference with other existing networks. Simulated gains were compered and majority of the results shows very much acceptable. We strongly believe that, the antenna can serve perfectly on practical working fields like, healthcare or sports facilities.

Notch signaling pathway. The proneural genes Mash1 and Ngn2 induce expression of notch ligands such as Dll1, which activate notch signaling in neighboring cells. Upon activation, the notch intracellular domain (NICD) is released from the transmembrane region and transferred into the nucleus, where NICD forms a complex with RBPj and induces Hes1 and Hes5 expression. Hes1 and Hes5 repress proneural gene expression. During maturation and trafficking to the cell surface, notch receptors undergo furin processing and glycosylation, which can impact their responsiveness to their ligands. The ligand-induced activation of notch signaling is dynamically regulated by endocytic trafficking, which can be modulated by the different ubiquitin ligases, such as Mind bom and Neuralized

Neurogenesis in the developing and adult forebrain. a Differentiation of NSCs in the embryonic dorsal telencephalon. NSCs initially undergo symmetric cell division and proliferate extensively. Then, these cells give rise to neurons or intermediate neural progenitors (INPs) by asymmetric cell division. Neurons and INPs migrate into the cortical plate (CP) and the subventricular zone (SVZ), respectively. INPs further divide in the SVZ and produce more neurons. Some NSCs become outer SVZ (OSVZ) or outer VZ (OVZ) progenitors, which have radial fibers that extend to the pial surface but lack apical processes. After production of neurons, NSCs finally differentiate into glial cells. b Neurogenic niche of the subventricular zone (SVZ) of the lateral ventricle (LV) of the adult brain. In this region, NSCs (type B cells) exist and new neurons are continuously generated. Type B cells are GFAP-positive cells with the structural and molecular characteristics of astrocytes. Type B cells divide to generate transit-amplifying cells (type C cells), which in turn differentiate into neuroblasts (type A cells) that migrate into the olfactory bulb. c Adult neurogenesis in the dentate gyrus (DG) of the hippocampus. Type 1 and type 2a progenitor cells in the subgranular zone (SGZ) are shown. These progenitor cells give rise to transit-amplifying cells (type 2b/type 3 cells). Then, transit-amplifying cells differentiate into dentate granule cells through several maturation steps

A wide range of notch ligands bind to and activate the notch receptor. The activity and availability of notch receptors and ligands are also regulated by endocytic trafficking, which can be modulated by various ubiquitin ligases [36]. Upon activation by ligands such as Dll1 on neighboring cells, notch receptors are cleaved by ADAM-family metalloproteases at site 2 (S2). The truncated transmembrane/intracellular domains are subjected to the further proteolytic events by presenilin proteases, such as PSEN1 or PSEN2, of the -secretase complex. -secretase cleaves the notch transmembrane domain progressively from site 3 (S3) to site 4 (S4).

To monitor notch signaling activity using Hes5 expression, our group visualized the expression of Hes5 by knocking in the nlsLacZ cDNA at the Hes5 locus (Hes5-nlsLacZ mice) (Fig. 3b) [11]. In this mouse strain, nuclear-localized -gal reporter protein encoded by the lacZ gene is expressed from the endogenous Hes5 promoter and mimics endogenous Hes5 expression. The resultant -gal was highly expressed in the VZ of the developing central nervous system, as expected. -gal was also expressed in the two germinal zones of the adult brain: the SVZ of the lateral ventricles and the SGZ of the hippocampal dentate gyrus [11].

In many cultured cells, including fibroblasts, myoblasts, and neuroblasts, a synchronized oscillatory Hes1 expression can be induced following serum stimulation or notch activation [63, 76, 77]. Hes1 oscillation is cell-autonomous and depends on negative autoregulation (Fig. 4c). After induction, Hes1 protein represses the expression of its own gene by directly binding to its promoter. This repression is short-lived due to the short half-life of the mRNA and protein. In this way, Hes1 autonomously initiates oscillatory expression with a periodicity of approximately 2 h, suggesting that Hes1 acts as a biological clock.

Although a role for oscillatory Hes1 expression has been extensively analyzed in somitogenesis, only recently has such an oscillatory pattern been observed in the embryonic nervous system [6, 80]. Real-time imaging and quantitative measurement of the bioluminescence signal of pHes1-Ub-Luc revealed the oscillation cycle of Hes1 in telencephalic NSCs to be ~2 h, consistent with that observed in other settings [80]. Notably, Ngn2 and Dll1 both display inverse correlations with Hes1 expression levels in NSCs, suggesting that Ngn2 and Dll1 expression also oscillates in these cells but with opposite phases to Hes1 oscillation. Real-time imaging showed that Ngn2 and Dll1 are indeed expressed in an oscillatory manner by dividing NSCs. It is likely that Ngn2 oscillation is regulated by Hes1 oscillation, while Dll1 oscillation is under the control of cyclic induction by Ngn2 and cyclic repression by Hes1. Dll1 expression then leads to activation of notch signaling between adjacent NSCs. Thus, Hes1-driven Ngn2 and Dll1 oscillations are essential for maintenance of a group of cells in an undifferentiated state by mutual activation of notch signaling [6, 80]. Therefore, real-time bioluminescence imaging of notch signaling activity revealed that it is under the control of more complex, and dynamic regulation than previously thought. Further study is required to fully understand the importance of oscillating notch activity and Hes expression in NSCs, particularly what kinds of biological events are dynamically coupled to Hes oscillation, for example, cell-fate determination, cell cycle progression, and regulation of adult NSC quiescence [4]. To understand these events, visualization of Hes1 promoter activity as well as real-time imaging of Hes protein dynamics are definitely required. be457b7860
