Galaxies grow through both internal and external processes. In about 10% of nearby red galaxies with little star formation, gas and stars are counter-rotating, demonstrating the importance of external gas acquisition in these galaxies. However, systematic studies of such phenomena in blue, star-forming galaxies are rare, leaving uncertain the role of external gas acquisition in driving evolutio...
Chronic venous insufficiency of the lower limbs is often underestimated and, in the absence of therapy, results in increasingly severe complications, including therapy-resistant tissue defects. Therefore, early diagnosis and adequate therapy is of particular importance. External counter pulsation (ECP) therapy is a method used to assist the venous system. The main principle of ECP is to squeeze...
This paper reports a micromachined Geiger counter with integrated permanent magnets that enhance the RF transmission from the discharges initiated by incident beta particles. With the intent of wireless sensing within the ultra wideband (UWB) spectrum, the transmission in the 2.0-2.8 GHz frequency range is investigated. The device consists of a 1x2 cm micromachined glass/Si cavity sandwiched be...
We study the well-posedness of biological models with AHL-dependent cell mobility on engineered Escherichia coli populations. For kinetic model proposed by Xue-Xue-Tang recently [17], local existence for large initial data is proved first. Furthermore, positivity and conservation laws density nutrient concentration assumptions (1.24) (1.26) are justified. Based these properties, it can be exten...
Intra-Aortic Balloon Pump Counter-Pulsation To the Editor: The imaging of coronary flow1 during intra-aortic balloon pumping is important and might be used to adjust the timing of balloon deflation better. In the series of figures shown by Ryan and Foster,1 with intra-aortic balloon pumping assisting every second beat, there was no consistent reduction of systolic pressure in the intervening un...
An implicit equation for the oscillation threshold of stimulated Brillouin scattering from Raman amplified signals in fibers with external feedback is derived under the assumption of no depletion. This is compared to numerical investigations of Raman amplification schemes showing good agreement for high reflectivities. For low reflectivities and high attenuation or long fibers, the assumption o...
We present an enhanced built-in self-test (BIST) architecture for high-performance circuits. Test patterns are generated by reseeding a twisted-ring counter. We show that a small number of seeds is adequate for generating test sequences that embed complete test sets for the ISCAS benchmark circuits. The seed patterns can either be stored on-chip or scanned in using a low-cost, slower tester. Th...
_____________ _ Skin plethysmography was used to monitor counter-pulsation by the intra-aortic balloon pump in 30 patients, 19 of whom came to coronary artery bypass grafting for pre-infarction angina. Skin plethysmography provided a reliable display of the arterial waveform and permitted correct adjustment of the timing and rate of balloon inflation and exhaust to produce maximum augmentation ...
