Atf1, the fission yeast homolog of activation transcription factor-2 (ATF-2), contributes to heterochromatin formation. However, the role of ATF-2 in chromatin assembly in higher organisms remains unknown. This study reveals that Drosophila ATF-2 (dATF-2) is required for heterochromatin assembly, whereas the stress-induced phosphorylation of dATF-2, via(More)
Previous studies have demonstrated a diversity of Bartonella spp. in rodent populations in Yunnan Province, China. Although Bartonella spp. have been isolated from cat fleas and cattle ticks collected from their animal hosts, little is known about Bartonella carried by rodent fleas. In this study, Bartonella DNA was detected by polymerase chain reaction(More)
Fruit maturation and ripening are genetically regulated processes that involve a complex interplay of plant hormones, growth regulators and multiple biological and environmental factors. Tomato (Solanum lycopersicum) has been used as a model of biological and genetic studies on the regulation of specific ripening pathways, including ethylene, carotenoid and(More)
Considering the characteristics of mobile network, we import three important parameters: distribution density of mobile phone, coverage radius of Bluetooth signal and moving velocity of mobile phone to build an epidemic model of mobile phone virus which is different from the epidemic model of computer worm. Then analyzing different properties of this model(More)
We describe a low cost embedded vision system in this paper. The goal of the system is to provide simple vision capabilities to small embedded systems in the form of an intelligent sensor. The system utilizes a low cost CMOS color camera module, a frame buffer chip and all image data is processed by a low cost microcontroller SX52. The system includes the(More)
This paper mainly introduces the application of Sunway ForceControl configuration software in the vehicle gasohol delivery system, and explains the hardware system structure and software implement. The system regards Sunway ForceControl configuration software as the development tools for host computer software. The vehicle gasohol delivery system can be(More)
Electric field induced reversible switchings of the magnetization and resistance were achieved at room temperature in epitaxial Mn:ZnO(110)/BiFeO3(001) heterostructures. The observed modulation of magnetic moment is ∼500% accompanying with a coercive field varying from 43 to 300 Oe and a resistive switching ratio up to ∼10(4)% with the applied voltages of(More)
Electric-field mediated magnetism was investigated in CoFe2O4 (CFO, deposited by reactive cosputtering under different oxygen flow rates) films fabricated on (011)-Pb(Mg1/3Nb2/3)0.7Ti0.3O3 (PMN-PT) substrates. Ascribed to the volatile strain effect of PMN-PT, the magnetization of the CFO films decreases along the [01-1] direction whereas it increases along(More)
In this paper, a low complexity adaptive EM-based channel estimation algorithm is proposed for Multiple Input Multiple Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems in slow time-varying frequency selective environment. The proposed algorithm was an adaptive channel estimation technique based on an expectation maximization (EM)(More)
The effects of indole-3-acetic acid (IAA) and the auxin transport inhibitors 2, 3, 5-triiodobenzoic acid (TIBA) and 1-N-naphthylphthalamic acid (NPA) on the style curvature of Alpinia platychilus, A. blepharocalyx, and A. mutica were studied. Exogenous IAA stimulated the style curvature movement of the anaflexistylous morph (ana-morph) and cataflexistylous(More)
