The agricultural machinery service (AMS) market enables China to rapidly realize mechanization on the basis of smallholder farmers. Academics generally believe that has created a model matches small-scale farmers with large-scale machinery. However, in recent years, transformation AMS from prosperity decline been under-analyzed. This paper used farm and supplier survey data North Plain estimate...

The nna1 gene mutation is associated with spontaneous degeneration of cerebellar Purkinje cells and germ cells in Ataxia and Male Sterility (AMS) mouse. Since nna1 is also expressed in hippocampal neurons, we investigated their vulnerability to hypoperfusion in AMS mouse. Eight-week-old male wild type (WT) and AMS mice were subjected to bilateral common carotid artery occlusion (BCCAO) for 10 m...

The measurement of cosmogenic radionuclides 10Be and 26Al by accelerator mass spectrometry (AMS) has become an invaluable tool for dating events processes in Quaternary geochronology, archaeology paleoanthropology. Here we present overview the current state research providing theoretical methodological background describe sample preparation AMS. We also summarize main geochronology calculation ...

In this paper we present a family of Mixed-signal (mixed analog/digital) synthesis tools being developed at the University of Cincinnati. The VASE (VHDL-AMS Synthesis Environment) project involves the development of a vertically integrated synthesis environment centered around the emerging VHDL-AMS standard for specification of analog and mixed signal systems. The unique contributions of this r...

This paper proposes VHDL-AMS syntax extensions that enable descriptions of AMS systems with partial differential equations. We named the extended language VHDL-AMSP. An important specific need for such extensions arises from the well known MEMS modelling difficulties where complex digital and analogue electronics interfaces with distributed mechanical systems. The new syntax allows descriptions...
