Novel reversible data hiding based on difference expansion
A novel reversible data hiding algorithm based on difference expansion called ACD was proposed, which used the so-called adaptive change direction technology. ACD embeds data by expanding the differences of neighboring pixel values.

ABSTRACT Background Type 1 plasminogen deficiency (PLGD‐1) is an ultra‐rare autosomal recessive disorder caused by variants in the PLG gene and affects approximately 1.6 individuals per million. The condition is characterized by decreased plasminogen levels and impaired function, resulting in fibrin‐rich lesions on mucous membranes throughout the body.

Reversible data hiding in encrypted images using recompression
To improve the performance of RDH (reversible data hiding) method in encrypted images,the embedding room was reserved before encryption and realizes the real separation of the data extraction from image decryption in op-eration.First,the feasibility of ...

The Role of “Adult‐Onset” Cancer Predisposition Genes in Pediatric Cancer: A Comprehensive Review
ABSTRACT Current literature estimates that 10% of pediatric cancers are caused by pathogenic or likely pathogenic (P/LP) germline variants in cancer predisposition genes (CPGs). Variants in CPGs thought to increase cancer risk exclusively during adulthood are referred to as “adult‐onset” CPGs (aoCPGs).

Composite Asymptotic Expansions and Difference Equations [PDF]
Difference equations in the complex domain of the form y(x+ϵ)−y(x)=ϵf(y(x))/y(x) are considered. The step size ϵ>0 is a small parameter, and the equation has a singularity at y=0. Solutions near the singularity are described using composite asymptotic expansions.

ABSTRACT Background Adolescents with haematological malignancies face significant emotional and relational challenges, often accompanied by difficulties in communicating their needs within the healthcare context. To address these issues, a narrative‐based psycho‐educational intervention based on the creation and prescription of Ironic Medications was ...

A Proposed Stochastic Finite Difference Approach Based on Homogenous Chaos Expansion
This paper proposes a stochastic finite difference approach, based on homogenous chaos expansion (SFDHC). The said approach can handle time dependent nonlinear as well as linear systems with deterministic or stochastic initial and boundary conditions. In

Human capital and firms’ markup: evidence from China
Based on the university enrollment expansion policy implemented by the Chinese government in 1999, I use the difference-in-difference method to explore the effects of human capital expansion on firms’ markup and the influencing mechanism.
