Visual secrete sharing (VSS) is an encryption technique that utilizes human visual system in the recovering of the secret image and it does not require any complex calculation. Pixel expansion has been a major issue of VSS schemes. A number of probabilistic VSS schemes with minimum pixel expansion have been proposed for binary secret images. This paper presents a general probabilistic (k, n)-VS...

sludge drying bed is preferred to mechanical methods due to the need for very simple technology. due to restriction of natural dewatering, we tried to eliminate some of these limitations by the tests and studies of assumptions. in this study, the effect of hydrostatic suction and sludge chemical conditioning has been studied in the natural sludge dewatering optimization. at first, hydrostatic s...

Transcription start site (TSS) evolution remains largely undescribed in Drosophila, likely due to limited annotations in non-melanogaster species. In this study, we introduce a concise new method that selectively sequences from the 5'-end of mRNA and used it to identify TSS in four Drosophila species, including Drosophila melanogaster, D. simulans, D. sechellia, and D. pseudoobscura. For verifi...

Transcription start site (TSS) evolution remains largely undescribed in Drosophila, likely due to limited annotations in non-melanogaster species. In this study, we introduce a concise new method that selectively sequences from the 50-end of mRNA and used it to identify TSS in four Drosophila species, including Drosophila melanogaster, D. simulans, D. sechellia, and D. pseudoobscura. For verifi...

OBJECTIVES No comparison of balloon- or self-expandable valved stents (VSs) regarding tissue injury (if any) has been reported yet. The objective was to evaluate the occurrence and compare the severity of traumatic injury to leaflets from balloon- or self-expandable VSs. METHODS Twelve homemade VSs were used for this experiment. These three-leaflet bovine pericardial bioprostheses had either ...

STUDY DESIGN A retrospective observational study. OBJECTIVE We evaluated the prevalence and clinical characteristics of tandem spinal stenosis (TSS) in patients with cervical myelopathy including ossification of the posterior longitudinal ligament of the cervical spine (C-OPLL). SUMMARY OF BACKGROUND DATA Concurrent cervical and lumbar spinal canal stenosis is generally reported as TSS. Mos...

The aim of the present study was to determine whether Cremophor EL is a suitable surfactant that can be routinely applied to pharmacokinetic (PK) studies in early drug discovery without influencing the intrinsic PK characteristics of the new chemical entities (NCEs). Cremophor EL, a polyoxyl 35 castor oil, has been used as a solubilization aid for water-insoluble compounds in pre-clinical drug ...

The round complexity of interactive protocols is one of their most important complexity measures. In this work we prove that existing lower bounds for the round complexity of VSS can be circumvented by introducing a negligible probability of error in the reconstruction phase. Previous results show matching lower and upper bounds of three rounds for VSS, with n = 3t + 1, where the reconstruction...
