Influence of triptolide on neuronal apoptosis in rat with cerebral injury after focal ischemia reperfusion by Deng-ming Wei, Guang-zhao Huang, Yi-gu Zhang, Guang-xun Rao.

Objective: To study effect of triptolide(TL) on neuronal apoptosis in cerebral tissue rat after ischemia-reperfusion. Method: Triptolide at dose 0.2 or 0.4 mg·kg -1was intr aperitoneally injected once a day for 4 d. The focal ischemia-rep erfusion model was established with thread embolism middle artery before trip tolide injection the fourth day. Neurological deficit score rats eval uated; and immunohistochemical techniques were used to count positive cells express MPO TUNEL tissue. Result: Compare d control group, neural function significantly impr oved, number infiltrate neutrophil cere bral remarkably reduced two TL-treated groups. Conclusio n: results suggested that TL can inhibit infiltration decrease degree [

Aphid resistant characteristics and the relations with physical characteristics of sorghum by Chang Jin-hua.

Aphid resistance characteristics and the relations with physical of different sorghum genotypes were studied under natural condition. The results show that aphid-resistance are controlled by dominate gene. Compared susceptible traits, leaves color resistant traitl ‘henong16’is light, wax content is lower surface more smooth ,the cells in Order tightly connect each other.

Precision PGC demodulation for homodyne interferometer modulated with a combined sinusoidal and triangular signal by Liping Yan, Zhouqiang Chen, Benyong Chen, Xie Jiandong, Shihua Zhang, Yingtian Lou, Enzheng Zhang.

A precision PGC demodulation for homodyne interferometer modulated with a combined sinusoidal and triangular signal is proposed. Using as additional modulation, continuous phase-shifted interference ellipse fitting generated whether the measured object in static or moving state. The real-time correction of AC amplitudes DC offsets quadrature components can be realized. merit this modulation that it eliminate thoroughly periodic nonlinearity resulting from influences light intensity disturbance, drift depth, carrier phase delay, non-ideal performance low pass filters conversional demodulation. principle realization processing are described detail. experiments accuracy rate evaluations fitting, nanometer, millimeter displacement measurements were performed to verify feasibility proposed experimental results show elliptical parameters achieved precisely real time nanometer was realized measurements.

Nonclassical higher-order photon correlations with a quantum dot strongly coupled to a photonic-crystal nanocavity by Tomas Sarmiento, Armand Rundquist, Michal Bajcsy, Arka Majumdar, Kevin A. Fischer, Konstantinos G. Lagoudakis, Sonia Buckley, Alexander Y. Piggott, Jelena Vuckovic.

We use the third- and fourth-order autocorrelation functions $g^{(3)}(\tau_1,\tau_2)$ $g^{(4)}(\tau_1,\tau_2, \tau_3)$ to detect non-classical character of light transmitted through a photonic-crystal nanocavity containing strongly-coupled quantum dot probed with train coherent pulses. contrast value $g^{(3)}(0, 0)$ conventionally used $g^{(2)}(0)$ demonstrate that in addition being necessary for detecting two-photon states emitted by low-intensity source, $g^{(3)}$ provides more clear indication source. also present preliminary data demonstrates bunching function as first step toward three-photon states.

Single-mode Brillouin fiber laser passively stabilized at resonance frequency with self-injection locked pump laser by Vasily V. Spirin, C. A. Lopez-Mercado, Patrice Mégret, Andrei A. Fotiadi.

We demonstrate a single-mode Brillouin fiber ring laser, which is passively stabilized at pump resonance frequency by using self-injection locking of semiconductor laser. Resonance condition for Stokes radiation achieved length fitting laser cavity. The generate single-frequency wave with linewidth less than 0.5 kHz approximately 17-m

Foreign Direct Investment and Exports Dynamics with Demand Learning

Foreign Direct Investment and Exports Dynamics with Demand Learning by Rossitsa Kotseva, Nikolaos Vettas.

We model a firm’s choice between exporting and investing in foreign country the presence of possibly persistent demand uncertainty. allow for shocks that, while increasing expected profit, impede learning. The firm learns gradually, Bayesian fashion, by observing past realizations. derive optimal exports investment paths, examine how they depend on technology parameters structure uncertainty show that learning alone may explain S-shape these paths. Immediate is possible despite uncertainty, if there are significant positive likely to take time.

Polling systems with parameter regeneration, the general case by Iain M. MacPhee, Mikhail Menshikov, Dimitri Petritis, Serguei Popov.

We consider a polling model with multiple stations, each Poisson arrivals and queue of infinite capacity. The service regime is exhaustive there Jacksonian feedback served customers. What new here that when the server comes to station it chooses rate parameters at random; these remain valid during whole stay station. give criteria for recurrence, transience existence sth moment return time empty state this model. This paper generalizes model, only two stations accept arriving jobs, which was considered in [Ann. Appl. Probab. 17 (2007) 1447–1473]. Our results are stated terms Lyapunov exponents random matrices. From recurrence can be seen parameter regeneration exhibit unusual phenomenon null over thick region space.
