A Color Image Encryption Technique Based on Bit-Level Permutation and Alternate Logistic Maps

Journal of Intelligent Systems, 2019
The paper presents an approach to encrypt the color images using bit-level permutation and alternate logistic map. The proposed method initially segregates the color image into red, green, and blue channels, transposes the segregated channels from the ...

Quad Key-Secured 3D Gauss Encryption Compression System with Lyapunov Exponent Validation for Digital Images

Applied Sciences, 2023
High-dimensional systems are more secure than their lower-order counterparts. However, high security with these complex sets of equations and parameters reduces the transmission system’s processing speed, necessitating the development of an algorithm ...

Construction of Robust Lightweight S-Boxes Using Enhanced Logistic and Enhanced Sine Maps

IEEE Access
Substitution boxes (S-Boxes) are essential elements of modern block ciphers, serving as non-linear characteristics that enhance the resistance of these ciphers against cryptanalysis.

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

Kink-antikink scattering in a quantum vacuum

Journal of High Energy Physics, 2022
We study kink-antikink scattering in the sine-Gordon model in the presence of interactions with an additional scalar field, ψ, that is in its quantum vacuum. In contrast to the classical scattering, now there is quantum radiation of ψ quanta and the kink-

Mapping and analysis of the LINE and SINE type of repetitive elements in rice [PDF]

Bioinformation, 2011
Non-LTR retrotransposons comprise significant portion of the plants genome. Their complete characterization is thus necessary if the sequenced genome is to be annotated correctly. The long and short interspersed nucleotide repetitive elements (LINE and SINE) may be responsible for alteration in the expression mechanism of neighboring genes, the ...

Comparative Drug Response Profiling in Neuroblastoma Cell Lines and Patient‐Derived Tumor Organoids

Pediatric Blood &Cancer, EarlyView.
ABSTRACT High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...
