We establish a motivic version of Adams’ vanishing line of slope 1 2 in the cohomology of the motivic Steenrod algebra over C.

Optical phase conjugation is demonstrated to enable simultaneous wide-band compensation of the residual dispersion and the fiber nonlinearities in dispersion-managed fiber transmission lines employing slope-compensating fibers. When the dispersion slope of transmission fibers is equalized by slope-compensating fibers, the residual dispersion and the slope of dispersion slope are compensated by ...

We continue our study of document marking t o deter illicit dissemination. A n experiment we performed reveals that the distortion on the photocopy of a document is very different in the vertical and horizontal directions. This leads to the strategy that marks a text line both vertically using line shifting and horizontally using word shifting. A line that is marked is always accompanied by two...

In this study, idealized simulations of squall line traversing a bell-shape mountain in a three-dimensional framework are conducted using the Weather Research and Forecasting (WRF) model, version 3.2.0, with 2-km horizontal grid size and 60 vertically stretched layers. Water vapor and condensate budgets are examined, and the temporal variations of four microphysics ratios, including precipitati...

Nearly all chemical processes fractionate 17O and 18O in a mass-dependent way relative to 16O, a major exception being the formation of ozone from diatomic oxygen in the presence of UV radiation or electrical discharge. Investigation of oxygen three-isotope behavior during thermal decomposition of naturally occurring carbonates of calcium and magnesium in vacuo has revealed that, surprisingly, ...

Taking the Quickbird optical satellite imagery of the small watershed of Beiyanzigou valley of Qixia city, Shandong province, as the study data, we proposed a new method by using a fused image of topography with remote sensing imagery (RSI) to achieve a high precision interpretation of gully edge lines. The technique first transformed remote sensing imagery into HSV color space from RGB color s...

In this paper, we propose a novel cascading approach, by cascading the feature selection method using mutual correlation with this symbolic approach. In the symbolic approach, the new dimensionality reduction method through transformation of features into symbolic data using the property of collinearity and variance based cumulative sum of features is used. The feature values are transformed in...

To explore the relation between myocardial and vascular injury in the generation of the no-reflow phenomenon, the pressure-flow relation during maximal vasodilation after coronary artery reperfusion was studied in the open-chest porcine model. During both endogenous and maximal vasodilation with intracoronary adenosine, pressure-flow (P/Q) plots were constructed before and after 20-minute (n = ...

high‑intensity focused ultrasound (hifu) is a novel treatment modality used by scientists and clinicians in the recent decades. this modality has had a great and significant success as a noninvasive surgery technique applicable in tissue ablation therapy and cancer treatment. in this study, radio frequency (rf) ultrasound signals were acquired and registered in three stages of before, during, a...

When a store sells items to customers, the store wishes to decide the prices of items to maximize its profit. Intuitively, if the store sells the items with low (resp. high) prices, the customers buy more (resp. less) items, which provides less profit to the store. So it would be hard for the store to decide the prices of items. Assume that the store has a set V of n items and there is a set E ...
