This paper introduces a number of modifications that allow for significant improvements of parallel LLL reduction. Experiments show that these modifications result in an increase of the speed-up by a factor of more than 1.35 for SVP challenge type lattice bases in comparing the new algorithm with the state-of-the-art parallel LLL algorithm.

This article presets a review of lattice problems. Paper contains the main eighteen problems with their reductions and referents to his cryptography application. As an example of reduction, we detail analyze connection between SVP and CVP. Moreover, we give an Ajtai theorem and demonstrate its role in lattice based cryptography.

PURPOSE To examine the predictive value of an early transcranial Doppler ultrasound (TCD) study performed in the emergency department in patients with spontaneous subarachoniod hemorrhage (SAH) in good neurological condition, in order to know which patients are at high risk of developing delayed cerebral ischemia (DCI). DESIGN A descriptive observational study was carried out involving a peri...

Two days of monocular deprivation (MD) of kittens during a critical period of development is known to produce a loss of visual responses in the primary visual cortex to stimulation of the nondeprived eye, and 7 days of deprivation results in retraction of axon branches and loss of presynaptic sites from deprived-eye geniculocortical arbors. The rapid loss of responsiveness to deprived-eye visua...

In this work, we give provable sieving algorithms for the Shortest Vector Problem (SVP) and Closest (CVP) on lattices in ?p norm (1?p??). The running time obtain is better than existing algorithms. We a new linear procedure that works all main idea to divide space into hypercubes such each vector can be mapped efficiently sub-region. achieve complexity of 22.751n+o(n), which much less 23.849n+o...

Plants detect changes in day length to induce seasonal patterns of flowering. The photoperiodic pathway accelerates the flowering of Arabidopsis thaliana under long days (LDs) whereas it is inactive under short days (SDs), resulting in delayed flowering. This delay is overcome by exposure of plants to high temperature (27°C) under SDs (27°C-SD). Previously, the high-temperature flowering respon...

Infectious pancreatic necrosis virus (IPNV) is a major viral pathogen of salmonid fish and causes serious economic losses to salmonid aquaculture. Previously, we demonstrated that the IPNV capsid protein, VP2, expressed in yeast self-assembles into subviral particles (SVPs) and injection of these IPNV rVP2 SVPs into rainbow trout elicits an immune response. Immunized fish had reduced viral load...
