Body Centric Wireless Communication (BCWC) has been topic of much research in recent years. In this manuscript, a novel low-cost microstrip patch antenna is designed for on-/off-body communication with a dual-band operation. The proposed structure exhibits a monopole-like radiation pattern at 2.45 GHz and a broadside radiation at 4.8 GHz, simultaneously. Lateral dimensions of 42 mm × 46 mm and ...

Lateral inhibition represents a well-studied example of biology's ability to self-organize multicellular spatial patterns with single-cell precision. Despite established biochemical mechanisms for lateral inhibition (e.g., Delta-Notch), it remains unclear how cell-cell signaling delays inherent to these mechanisms affect patterning outcomes. We investigate a compact model of lateral inhibition ...

The High-Voltage MOSFET is used in a wide variety of applications covering from power systems up to RF-IC. Compact models that describe the high-frequency behavior of the device are required to predict high-frequency operation and switching capabilities of these elements in HV state-of-the-art systems. In this paper, an RF model is presented and verified against extensive Y-parameter measuremen...

Channel bonding is one of the strategies considered in the IEEE 802.11ac amendment to improve the performance of Wireless Local Area Networks (WLANs). However, besides the obvious gains attainable from using wider channels in terms of higher achievable transmission rates, there are also several potential drawbacks that may seriously compromise the overall WLAN performance, most notably the high...

In this paper the spectrum of barotropic basin modes of the Argentine Basin is shown to be connected to the classical Rossby basin modes of a flat-bottom (constant depth), rectangular basin. First, the spectrum of basin modes is calculated for the Argentine Basin, by performing a normal-mode analysis of the barotropic shallow-water equations. Then a homotopy transformation is performed that gra...

The measurement of electromagnetic interference can be performed e.g. on open area test sites with different shapes and sizes, which are defined in ANSI C63.4 [1] and CISPR 16-1 [2]. For EMC compliance measurements the normalized site attenuation (NSA) has to be measured and compared with the calculated NSA [3]. If the deviation is too high, an extension of the groundplane is recommended. This ...

The gut-innervating stomatogastric nervous system of Drosophila, unlike the central and the peripheral nervous system, derives from a compact, single layered epithelial anlage. Here we report how this anlage is initially defined during embryogenesis by the expression of proneural genes of the achaete-scute complex in response to the maternal terminal pattern forming system. Within the stomatoga...

An experiment at NASA Ames' Vertical Motion Simulator (VMS) evaluated three motion tuning methods using the GenHel UH-60A Black Hawk math model. For each of the three motion tuning methods, adjustments were made to the gain and washout frequency of the high pass filter designed to attenuate the math model accelerations before commanding the simulation motion platform. Two of the tuning methods ...

In recent years, nonlinear calculation methods can be easily carried out by means of developing computer technologies. In this way, comparisons of the nonlinear methods have started to increase rapidly and more studies are carried out on regular and irregular buildings. However, it is most important to compare consistency of the methods on buildings. In this study, most common nonlinear static ...
