We empirically study the market impact of trading orders. We are specifically interested in large trading orders that are executed incrementally, which we call hidden orders. These are statistically reconstructed based on information about market member codes using data from the Spanish Stock Market and the London Stock Exchange. We find that market impact is strongly concave, approximately inc...

Many traditional time series model has been widely applied in forecasting Problem. However, the previous time series methods still have some constraints: (1) conventional time series models only considered single variable; (2) traditional fuzzy time series model determined the interval length of linguistic value subjectively; (3) selecting variables depended on personal experience and opinion. ...

Tomato plants (Lycopersicon esculentum, var. Better Boy) were stably transformed with a gene consisting of the open reading frame of a prosystemin cDNA under the regulation of the cauliflower mosaic virus 35S promoter. The leaves of the transgenic plants constitutively produced proteinase inhibitor I and II proteins, which accumulated over time to levels exceeding 1 mg/g of dry leaf weight. Thi...

Morphological characteristics of rooted cuttings and seedlings of four open-pollinated loblolly pine families cultured at the G.H.W. Weyerhaeuser Nursery near Washington, North Carolina were assessed after lifting. Cuttings were visually assigned to nine grading classes and six putative cull classes. The nine grading classes represented a factorial of three root collar diameter classes (small [...

The performance of container and bareroot loblolly pine (Pinus taeda L. ) seedlings from the same improved seedlot was compared on highly productive bottomland sites in South Carolina. At the time of planting, size and quality of the open-grown container stock were equal to or better than bareroot material. When outplanting conditions were ideal, field plantings in March, April, and May of 2 su...
