The linewidth enhancement factor (LEF) has recently moved into the spotlight of research on frequency comb generation in semiconductor lasers. Here we present a novel modulation experiment that enables direct measurement spectrally resolved LEF laser comb. By utilizing phase-sensitive technique, are able to extract for each individual mode any type. We first investigate and verify this universa...

the genetic polymorphism of some genes related to meat production in three egyptian sheep breeds (barki, rahmani and osseimi) was studied. the candidate genes were: calpastatin, myostatin, diacylglycerol-acyltransferase1, insulin-like growth factor binding protein-3 and booroola fecundity gene. the technique applied was the restriction fragment length polymorphism for the polymerase chain react...

objective(s):to study the effect of low-frequency vibration on bone marrow stromal cell differentiation and potential bone repair in vivo. materials and methods:forty new zealand rabbits were randomly divided into five groups with eight rabbits in each group. for each group, bone defects were generated in the left humerus of four rabbits, and in the right humerus of the other four rabbits. to t...

It has been suggested that at least two mechanisms mediate disparity processing, one for coarse and one for fine disparities. Here we analyze individual differences in our previously measured normative dataset on the disparity sensitivity as a function of spatial frequency of 61 observers to assess the tuning of the spatial frequency channels underlying disparity sensitivity for oblique corruga...

In the design of high Quality factor (Q) micro or nano beam resonators, different dissipation mechanisms may have damaging effects on the quality factor. One of the major dissipation mechanisms is the thermoelastic damping (TED) that needs an accurate consideration for prediction. In this paper, thermoelastic damping of the longitudinal vibration of a homogeneous micro beam with both ends clamp...

this paper presents a new centralized adaptive method under frequency load shedding. sometimes, after initial frequency drop following severe disturbances, although the system frequency returns to its permissible value, however, the system might become unstable due to voltage problems. in this regard, the paper proposes a new centralized adaptive load shedding method to enhance the voltage stab...

We use the Nambu-Jona-Lasinio model as an effective quark theory to investigate the medium modifications of the nucleon electromagnetic form factors. By using the equation of state of nuclear matter derived in this model, we discuss the results based on the naive quark-scalar diquark picture, the effects of finite diquark size, and the me-son cloud around the constituent quarks. We apply this d...

The amount of demand for new products like 3G is related to adoption and spread of innovations. Research suggests that innovativeness is related to consumer behavior and characteristics. Research shows that new technologies like 3G are not evaluated by only its functional sides in the consumer perception. Consumers also perceive symbolic sides to this type of technology. This study measures the...
