Introduction This application note is focused on exploiting the RF design capabilities of HFA3046/3096/3127/3128 transistor arrays. Detailed design procedures, using these transistor arrays, for a matched (800MHz to 2500MHz) high-gain low-noise amplifier and a 10MHz to 600MHz wideband feedback amplifier are described. The HFA3046, HFA3096, HFA3127, HFA3128 transistor arrays are fabricated in a ...

We have performed a three-generation, forward genetic screen to identify recessive mutations that affect the patterning of the peripheral nervous system. Using this assay, we identified Sema3A(K108N), a novel loss-of-function allele of Sema3A. Class 3 semaphorins, which include Sema3A, are structurally conserved secreted proteins that play critical roles in the development and function of the n...

Low frequency noise characteristics of new high voltage, high performance complementary polysilicon emitter bipolar transistors have been studied. The influence of the base biasing resistance, emitter geometry, and temperature on the noise spectra are discussed. The npn transistors studied exhibited 1/f and shot noise. The pnp transistors, on the other hand, are characterized by significant gen...

Odorant-binding proteins (OBPs), also named pheromone-binding proteins when the odorant is a pheromone, are essential for insect olfaction. They solubilize odorants that reach the port of entry of the olfactory system, the pore tubules in antennae and other olfactory appendages. Then, OBPs transport these hydrophobic compounds through an aqueous sensillar lymph to receptors embedded on dendriti...

Three different batches of dry fermented Chinese-style sausages; CHS-LC, CHS-SX and CHS-SL were prepared separately inoculating with Lactobacillus casei subspp casei-1.001, Staphylococcus xylosus-12 and a mixture of these two starters in equal proportion. The water activity and pH ranged from 0.795 to 0.826 and 4.10 to 5.26 respectively with no significant difference in weight losses in final p...

The abundance of N in various fractions in maize (Zea mays L.) grain was compared in two genotypes, a normal hybrid (Pioneer 3369A) and its opnque-2 (0-2) counterpart (L3369). Plants were grown in the greenhouse in sand cultures irrigated daily with nutrient solutions containing 3.75 mM N as NO, ion. At anthesis the plant cultures were divided into sets, one set continuing to be irrigated with ...

INTRODUCTION The last decade has seen a massive device research effort in Si and SiGe NPN bipolar transistors. The fate of Si technology had already been prematurely declared a few years ago when it was estimated that conventional Si NPN devices would never see their cut-off frequencies go beyond the 5-10 GHz range. Surprisingly, the early to mid 90’s has seen an explosion in Si NPN bipolar dev...

Nitrogen components of yoghurt milk samples and resulting probiotic set yoghurt weredetermined. Analyses included total nitrogen (TN), non-casein nitrogen (NCN), non-proteinnitrogen (NPN), casein nitrogen (CN) and proteolysis index (PI). Yoghurt samples wereanalyzed 1, 7, 14 and 21days after production and storage at 5±1°C. TN, CN and PI contentsof yoghurt milk samples with high Somatic Cell SC...

We consider the probabilistic relationship between the value of a random asymmetric traveling salesman problem ATSP (M) and the value of its assignment relaxation AP (M). We assume here that the costs are given by an n × n matrix M whose entries are independently and identically distributed. We focus on the relationship between Pr(ATSP (M) = AP (M)) and the probability pn that any particular en...
