Abstract We report bias enhanced nucleation and growth of boron-rich deposits through systematic study the effect a negative direct current substrate during microwave plasma chemical vapor deposition. The flowing silicon with an applied −250 V was investigated for feedgas containing fixed hydrogen (H 2 ) flow rate but varying argon (Ar) rates 1330, 2670, 4000 Pa chamber pressure. For 1330 2670 ...

BACKGROUND Because of risk of outlet strut fracture, prophylactic replacement should be considered for Björk-Shiley convexo-concave (BScc) valve recipients. We assessed the effects of epidemiological and decision-analytic guidelines on actual BScc valve replacement. METHODS AND RESULTS We performed a retrospective cohort study including all 2263 Dutch BScc patients with a mean follow-up of 11...

Original scientific paper In wireless sensor networks, efficient communication is the ultimate goal of a wireless medium access control (MAC) protocol. Concurrent transmission is one of the main ways to solve the issues of traditional MAC protocols with low throughput and accumulated delay in wireless sensor networks with highload and intensive nodes. In this paper, a novel concurrent transmiss...

In this paper, an optical waveguide junction is introduced to reduce crosstalk based on a hexagonal structure of photonic crystals for TE modes. The wavelength is 1330 nm which is an important wavelength for optical fiber data transmission. Simulation results show that the proposed design exhibits a reduction of -50 dB in crosstalk. It translates to a considerable isolation improvement between ...

Subject review Crash detection sensors play a vital role in vehicular safety applications. One of the major applications of these sensing systems is the use in occupant restraint systems. Besides, sensors are extensively used in the accident mitigation and advanced vehicle control system. Crash sensors have advanced significantly in the last few decades. Yet, existing demands and challenges bri...

Original scientific paper Recently, RFID technology has been widely used in many applications such as object monitoring and tracing due to the unique features such as noncontact, automatic, fast and multi-target identification simultaneously. However, because of the interference of environmental factors and the requirement of real-time detection, the data collected by the RFID readers are often...
