Single-photon avalanche diodes photon detection efficiency (PDE) and breakdown uniformity are studied. An approach to increase the PDE based on controlled breakdown of the peripheral region of the junction is described. Parameters influencing and controlling the peripheral region breakdown are discussed. A collection efficiency >60% is demonstrated, nearly twice that of a conventional, planar breakdown device. © 1963-2012 IEEE. Source

This work demonstrates the development of electro-mechanical sensors using a generic methodology based on elastomeric conductive nanocomposites. A fast and facile fabrication route is used to construct a unique architecture based on polymerization of aniline in the presence of dissolved styrene-isoprene-styrene (SIS) tri-block copolymer and carbon nanotubes (CNT), followed by a precipitation-filtration step. The resulting nanocomposites form a segregated network of conductive pathways containing CNT. The percolation threshold calculated for aniline and CNT is 0.8 and 0.2wt%, respectively. The electro-mechanical sensors have demonstrated a stable and fast dynamic response with a uniform electrical amplitude to the applied strain cycles for two diverse polymer matrices. An accurate dynamic behavior, where the maximum peak of relative electrical resistance coincides with the maximum strain peak, was achieved. The relatively high calculated sensitivity factor (gauge factor) demonstrates that the nanocomposites developed possess good sensing performance. The unique method used for the preparation of SIS/CNT/polyaniline nanocomposites, results in new strain sensors and it can be utilized for evaluation of constructive damage in different composite structures. © 2015 John Wiley & Sons, Ltd.

Complementary metal-oxide-semiconductor (CMOS) technology is dominant in the microelectronics industry for a wide range of applications, including analog, digital, RF, and sensor systems. The advantages of silicon CMOS technology compared to bipolar technology as well as transistors in other semiconductors is well-established. CMOS technology scaling has been a main drive for continuous progress in the silicon based semiconductor industry over the past two decades [1]. The continuous downscaling of CMOS technologies towards nano feature size has increased the performance of integrated circuits considerably. However, one important limitation of MOSFET downscaling is an increase of 1/f noise (often referred to as low-frequency noise), since the 1/f noise increases as the reciprocal of the device area [2], [3]. Furthermore, the development of nano-sized CMOS technologies has led to the observation of random telegraph signals (RTS) [4] yielding large low frequency current fluctuations. Excessive low-frequency noise introduces serious limitations on the functionality of analog and digital circuits since it deteriorates the noise figure of operational amplifiers and A/D and D/A converters. Lowfrequency noise diminishes the signal-to-noise-ratio (SNR) of CMOS sensors, such as IR or CMOS image sensors [5] [6]. The 1/f noise is also of paramount importance in RF circuit applications where it gives rise to phase noise in oscillators or multiplexers [7]. The 1/f noise is a sensitive diagnostic tool to monitor radiation effects on MOSFETs [8]. © 2011 IEEE. Source

Although 90 % of all bird species are monogamous, many species practice alternative reproductive strategies as extra-pair copulations, intra-specific brood parasitism, and quasi-parasitism. In territorial monogamous species, both partners hold and defend the territory from intruders. Often, the intruders are males and usually the local male banishes the intruders. Indeed, many studies focused on the response of the local male toward intruder males. However, the benefits and costs associated with the responses of the local male toward intruder females have been largely overlooked. Focusing mainly on alternative reproductive strategies, we developed a model to predict the aggression a monogamous male may demonstrate toward an intruder female during the pre-egg laying stage of his local female partner. This model demonstrates that the intensity of aggression that the local male shows toward an intruder female depends on the extra-pair copulations that his local female partner may perform. Further, the aggression also depends upon intra-specific brood parasitism and quasi-parasitism that might be carried out by the intruder female. Our approach suggests that when considering mating strategies, there is a need to assess how these three alternative reproductive strategies may affect the local male's aggression toward intruder females. © 2013 Springer-Verlag Berlin Heidelberg and ISPA.

Objectives: To examine the impact of electronic media (EM) use on teenagers’ life satisfaction (LS) and to assess the potential moderating effect of supportive communication with parents (SCP). Methods: Data were drawn from the cross-national Health Behaviour in School-aged Children (HBSC) study (2009/2010) in Canada, England, Germany, Hungary, Italy, Israel, The Netherlands, Poland and Scotland. Sample size: 53,973 students aged 11–15 years. Results: More hours per day spent on the computer were associated with lower LS; more EM communication with friends with higher LS. This relationship became negative if EM use reached and exceeded a certain threshold. SCP moderated the effect of EM communication with friends, but not computer use for the total sample. SCP seems to be more important than computer use or EM communication with friends for LS and it seems to buffer negative effects of EM use. Conclusions: Communication with parents seems to buffer the negative effects of EM use on LS during adolescence. Higher computer use was related to lower LS, but “optimal” frequency of EM communication with friends was country specific. © 2014, Swiss School of Public Health. Source
