Short‐Term Stock Price Prediction Based on Limit Order Book Dynamics

Interaction of capital market participants is a complicated dynamic process. A stochastic model is proposed to describe the dynamics to predict short‐term stock price behaviors. Independent compound Poisson processes are introduced to describe the occurrences of market orders, limit orders and cancellations of limit orders, respectively. Based on high‐frequency observations of the limit order book, the maximum empirical likelihood estimator (MELE) is applied to estimate the parameters of the compound Poisson processes. Moreover, an analytical formula is derived to compute the probability distribution of the first‐passage time of a compound Poisson process. Based on this formula, the conditional probability of a price increase and the conditional distribution of the duration until the first change in mid‐price are obtained. A novel approach of short‐term stock price prediction is proposed and this methodology works reasonably well in the data analysis. Copyright © 2016 John Wiley & Sons, Ltd.     

Cyclic CMP (cytidine 3′,5′-monophosphate) suppresses changes in human sperm amplitude of lateral head displacement and hyperactivation

Summary The dibutyryl analog of cCMP suppressed sperm amplitude of lateral head displacement and hyperactivation. Sperm motility was inhibited by dibutyryl cCMP with a shift toward less linear trajectory sperm movements. The results suggest a role of cCMP as an inhibitory signal on sperm motility patterns related to sperm capacitation.     

Effects of lipid soluble antioxidants on cytotoxicity induced by photochemical products of cholesterol

Summary Lipid soluble antioxidants, butylated hydroxytoluene and vitamin E, were shown to suppress cytotoxicity induced by cholesterol-derived photoproducts in Chinese hamster embryo cells. These cholesterol-derived photoproducts were rather toxic.This study was supported by USPHS grant CA23684 awarded by the National Cancer Institute, NIH, DHEW.     

ABT生根粉对大豆重迎茬的保产效应及其机理

经１９９３￣１９９４年的田间试验证明，重迎茬大豆经ＡＢＴ生根粉处理后，能提高出苗率，降低土壤中孢囊线虫孢囊数量，减轻大豆孢囊线虫病害，增加苗期根际细菌及根瘤菌数量，增加根数，根重，根瘤重量、干物质积累，单株籽粒数量及产量，其产量与正茬对照相当，具有保产作用。     

Regulation of mouse trophoblast giant cell nucleus development in hatched mouse blastocysts by cyclic cytidine 3',5'-monophosphate (cCMP)

The dibutyryl analog of cCMP enlarged the nuclei of trophoblast giant cells and promoted blastocyst development. The result suggests that cCMP has a trophic effect on embryonic development, specifically by altering the size of the trophoblast cell nucleus but does not enhance trophoblast cell proliferation processes.     

Both thermal and nociceptive afferents influence the unit activity of the neurons in the corpus striatum

Both thermal and nociceptive stimulation in the periphery were shown to influence the neuronal activity recorded in the striatal area. Both the thermal and nociceptive sensitivity of the striatal neurons were closely related.     

Does acute obstruction of the common bile duct produce distension of the rat bile tree?

Zusammenfassung Der Gallenausfluss, der bei akuter Verstopfung des Hauptgallentraktes beobachtet wird, scheint durch den elastischen Nachreflex des ausgedehnten Gallentraktes verursacht.     

The effect of cyclic cytidine 3′,5′-monophosphate (cCMP) on the in vitro development,hatching and attachment of the mouse blastocyst

Summary The in vitro development and attachment of hatched mouse blastocysts on the untreated substratum was enhanced by 10 M dibutyryl cCMP (dbcCMP). The result suggests that cCMP has an effect on embryonic development and on the blastocyst attachment process.25 November1986
