Robust steganographic framework for securing sensitive healthcare data of telemedicine using convolutional neural network

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Data is the key element that runs the modern society. Large amounts of data are being released day by day as a result of many activities. The digital data is transferred through the Internet which may be vulnerable to attacks while transmitting. Especially, the medical data is observed to be of at most importance.

Combination and comparison of AES and RC4 cryptography in least significant bit (LSB) method in digital image to improve message security

Jurnal Informatika, 2018
Message security is something that must be kept secretly. However, to maintain the security and the secret of a message it takes two different methods. To maintain the security of messages, the science that has been widely used is to use cryptography. As

Spectroscopic and photometric studies of low-metallicity star-forming dwarf galaxies. I. SBS 1129+576

, 2003
Spectroscopy and V,I CCD photometry of the dwarf irregular galaxy SBS 1129+576 are presented for the first time. The CCD images reveal a chain of compact H II regions within the elongated low-surface-brightness (LSB) component of the galaxy.

Relationship Between Fecal Bile Acid Profile and Intestinal Microbiota in Patients With Chronic Radiation Enteritis

Journal of Digestive Diseases, EarlyView.
Patients with chronic radiation enteritis (CRE) demonstrate dysregulated bile acid (BA) metabolism, characterized by an increased proportion of primary BAs and a decreased proportion of secondary BAs. Moreover, the diversity of the intestinal microbiota is significantly reduced in individuals with CRE, and there is a bidirectional interaction between ...

Management of retinopathy of prematurity in a tertiary referral neonatal intensive care unit: Treatment rates and the impact of outsourcing laser therapy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To describe the treatment rate for retinopathy of prematurity (ROP) at a tertiary referral neonatal intensive care unit (NICU) in the south‐western region of the Netherlands. In addition, we evaluated the impact of outsourcing laser treatment, implemented in 2018, by comparing treatment characteristics from 3 years prior and 3 years ...

Using continuous visual stimulus tracking for detecting visual function loss due to acquired brain injury

Acta Ophthalmologica, EarlyView.
Abstract Purpose Acquired brain injury (ABI) may cause homonymous visual field (VF) defects. Standard automated perimetry (SAP) is the gold standard for VF assessment, but it can be challenging in ABI. Continuous visual stimulus tracking (SONDA; Standardised Oculomotor and Neurological Disorders Assessment) simplifies the perimetric task to following a
