Timbers of multiple tree species and sizes are often traded in a single market. Some previous studies have empirically examined their price interdependences, but the drivers such relationships remain unclear. I demonstrated with rational expectations model that when timbers two (or sizes) were gross substitutes production, steady-state ratio between prices was dependent on relative quality ease...
Chinese characters that are similar in their pronunciations or in their internal structures are useful for computer-assisted language learning and for psycholinguistic studies. Although it is possible for us to employ imagebased methods to identify visually similar characters, the resulting computational costs can be very high. We propose methods for identifying visually similar Chinese charact...
This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...
Among the biodiversity of soil microorganisms, bacteria have the basic role in soil functions. In order to determine the diversity and abundance of soil bacteria in arid regions, and also to study the effect of agricultural practices on them, a study was conducted in winter wheat fields on Shirvan, Mashhad and Gonabad. In each region, high and low input fields of winter wheat and a natural syst...
