Recently reversible data hiding (RDH) is getting more and more attention in encrypted images, as it maintains the excellent property that the original image cover can be losslessly recovered after the embedded data is extracted while image and data are protected and are confidential.This paper presents a method for reversible data hiding using circular hough transformation(CHT). CHT detects the...

BACKGROUND In 2003, the Accreditation Council for Graduate Medical Education (ACGME) mandated 80-hour resident duty limits. In 2011 the ACGME mandated 16-hour duty maximums for PGY1 (post graduate year) residents. The stated goals were to improve patient safety, resident well-being, and education. A systematic review and meta-analysis were performed to evaluate the impact of resident duty hours...

The cusped NFW universal density profile suggested by typical CDM models has been challenged in recent years by the discoveries of the soft cores with finite central density for a broad range of masses from dwarf galaxies to clusters of galaxies. It is thus desirable that a new, analytic model would instead become available for virialized dark halos. One promising candidate is probably the empi...

The advanced RDH work focuses on both data encryption and image encryption which makes it more secure and free of errors. All previous methods embed data without encrypting the data which may subject to errors on the data extraction or image recovery. The proposed work provides a novel RDH scheme in which both data and image can be encrypted and extracted reversibly without any errors. In the p...

Virtually nothing in nature is uniform. Observed at the right scale, most entities are clustered rather than evenly distributed, spatially and temporally, and this applies across domains from the distribution of matter in the universe, to habitats across the Earth’s surface, and to energy in the landscape. Patchiness means organisms cannot carve out even territories. Instead, their shape and si...

Separable Reversible Data Hiding in Encryption Image (RDH-EI) has become widely used clinical and military applications, social cloud security surveillance recent years, contributing significantly to preserving the privacy of digital images. Aiming address shortcomings works that directed achieve high embedding rate by compensating image quality, security, reversible separable properties, we pr...

Intervertebral disc herniation is one of the most common causes of back and extremity pain. The most commonly used surgical treatment is lumbar discectomy. About 0.5-25% go on to develop recurrent disc herniation (rDH) after a successful first discectomy. Currently, there aren't any guidelines to assist surgeons in determining which approach is most appropriate to treat rDH. A recent survey sho...

Vertebrate vision starts with photoisomerization of the 11-cis-retinal chromophore to all-trans-retinal. Biosynthesis of 11-cis-retinal is required to maintain vision. A key enzyme catalyzing the oxidation of 11-cis-retinol is 11-cis-retinol dehydrogenase (11-cis-RDH), which is encoded by the RDH5 gene. 11-cis-RDH is expressed in the RPE and not in the neural retina. The consequences of a lack ...

In this paper, a reversible data hiding scheme based on two dimensional difference histogram modification is proposed. We adopted difference-pairmapping (DPM) strategy. A sequence of pairs of difference values is calculated by taking each pixel-pair and its surroundings. Then, a two-dimensional difference-histogram is produced by counting the frequency of the resulting difference pairs. Then, a...
