Rotational smoothing is a phenomenon consisting in gain of regularity by means averaging over rotations. This present operators that regularize only certain directions, contrast to regularizing all directions. The the result rotating directions where corresponding operator performs effect. In this paper we carry out systematic study rotational for class includes k-vector-space Riesz potentials ...

objective: in this article, a numerical study is conducted on mixing of two fluids in the liquid phase with two different concentrations of a chemical species in the electro-osmotic flow. methods: the base liquid is an electrolyte which flows in a two-dimensional micro-channel having electrically charged walls. lorentz electric force, which is used as stimulating flow factor, is created by appl...

background: hyperthyroidism as a risk factor for stroke is not conclusive. there are no definite data on the relationship between ischemic cerebrovascular injury and hyperthyroidism. this study was designed to define whether the outcomes of post-ischemic stroke injury are influenced by chronic hyperthyroidism. methods: two groups of hyperthyroid (ht) and control euthyroid rats of equal numbers ...

The fusion probability for the production of superheavy nuclei in cold reactions was investigated and compared with recent experimental results $^{48}$Ca, $^{50}$Ti, $^{54}$Cr incident on a $^{208}$Pb target. Calculations were performed within fusion-by-diffusion model (FbD) using new nuclear data tables by Jachimowicz et al. It is shown that could be well explained framework FbD model. saturat...

Rotational atherectomy (RA) for heavily calcified lesions is essential for improved stent delivery and stent expansion. In tortuous vessels it is often difficult to advance the burr without rotation and possible injury to the endothelium of healthy vessel. The GuideLiner catheter, a child in mother catheter, has recently been used to allow for increased support for delivery of stents through to...

Rotational cryptanalysis is a statistical method for attacking ARX constructions. It was previously shown that ARX-C, i.e., ARX with the injection of constants can be used to implement any function. In this paper we investigate how rotational cryptanalysis is affected when constants are injected into the state. We introduce the notion of an RX-difference, generalizing the idea of a rotational d...
