This paper presents the design, simulation and characterization of a new type of in-plane thermal unimorph, which utilizes composite SU-8/silicon microstructures. The unimorph consists of a silicon skeleton and SU-8 photoresist, which encapsulates the silicon skeleton. The silicon skeleton is asymmetric in shape, consisting of a straight segment and a meandering segment. Gaps and surrounds of t...

Abstract Introduction Regular aerobic exercise reverses aging-induced deterioration of arterial stiffness via an increased nitric oxide (NO) production. Concurrently, asymmetric dimethylarginine (ADMA), endogenous inhibitor NO synthase, was decreased by training. A recent study showed that the NOx/ADMA ratio reflects endothelial function and may be index states cardiovascular disease. However, ...

this paper investigates asymmetric behaviors of income inequality and consumption expenditures inequalities, the relationships between them and sketches their trends in the iranian households’ survey for the period of 1979 to 2006. for this purpose, and to analyze the relationships between variables panel data methodology was employed. results indicate that all the fluctuations of income inequa...

This paper examines downward price rigidity in Iranian house market and discusses whether this characteristic would result in an asymmetric relationship between house price and monetary policy. To test the downward house price rigidity the threshold GARCH model is employed. The asymmetric adjustment to monetary policy is examined using the asymmetric cointegration and error correction models. T...

credence goods market is one of the markets that the asymmetric information has transformed it to a missing market. those goods and services that the applicant cannot determine the exact amount of their expenses due to the asymmetric information are called credence goods. from the economists' perspective, transaction in a market where participants are ignorant about each other is a game wi...

background oxidative stress plays a major pathogenic role in liver injury following chronic hepatitis b. glutathione peroxidase (gpx) has a central role in regulating the oxidative state. hepatitis b virus (hbv) results in down-regulation of gpx. on the other hand, iron homeostasis is disrupted in hbv infected patients. therefore, the objective of this study was to assess the interplay of gpx a...

the deformation and stiffness characteristics of a cemented gravely sand was investigated using triaxial equipment. the triaxial tests were conducted in both dry and saturated undrained conditions. artificially cemented samples are prepared using gypsum plaster as the cementing agent. the plaster was mixed with the base soil at the weight percentages of 1.5, 3, 4.5 and 6. the applied confining ...

During asymmetric division, a cell polarizes and differentially distributes components to its opposite ends. The subsequent division differentially segregates the two component pools to the daughters, which thereby inherit different developmental directives. In Drosophila sensory organ precursor cells, the localization of Numb protein to the cell's anterior cortex is a key patterning event and ...
