An improved reversible image watermarking algorithm based on difference expansion

open access: yesInternational Journal of Distributed Sensor Networks, 2017
To improve the visual quality and the embedding rate of the existing reversible image watermarking algorithm, an improved reversible image watermarking algorithm based on difference expansion is proposed.

Two-layers robust data hiding scheme for highly compressed image exploiting AMBTC with difference expansion

open access: yesJournal of King Saud University: Computer and Information Sciences, 2022
When the secret message is placed inside a highly compressed image, the transmission will be more secure and cost efficient. In this article, two-layer data embedding and extraction approaches are provided that use a combination of Absolute Moment Block ...

Evaluating `elliptic' master integrals at special kinematic values: using differential equations and their solutions via expansions near singular points [PDF]

open access: yes, 2018
This is a sequel of our previous paper where we described an algorithm to find a solution of differential equations for master integrals in the form of an $\epsilon$-expansion series with numerical coefficients.

BOSONIZATION AND THE EIKONAL EXPANSION: SIMILARITIES AND DIFFERENCES [PDF]

open access: yesInternational Journal of Modern Physics B, 1996
We compare two non-perturbative techniques for calculating the single-particle Green’s function of interacting Fermi systems with dominant forward scattering: our recently developed functional integral approach to bosonization in arbitrary dimensions, and the eikonal expansion.

Reversible data hiding in encrypted images using recompression

open access: yesTongxin xuebao, 2015
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 ...

Visual onset expands subjective time [PDF]

open access: yes, 2006
We report a distortion of subjective time perception in which the duration of a first interval is perceived to be longer than the succeeding interval of the same duration. The amount of time expansion depends on the onset type defining the first interval.

Evaluation of the Utility of Baseline Echocardiogram in Patients With Standard Risk Precursor B‐Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
Abstract Background A routine baseline echocardiogram is often obtained prior to anthracycline administration in children with cancer. The utility of baseline echocardiogram is unclear in patients with standard risk B‐cell acute lymphoblastic leukemia (SR B‐ALL) as their anthracycline cumulative dose is low.

Information hiding scheme for digital images using difference expansion and modulus function

open access: yesJournal of King Saud University: Computer and Information Sciences, 2019
Disguising the presence of communication has become a severe concern in this highly digitalized world due to the unauthorized data access and network policy violations that are emerging rapidly.

CPX‐351 in High‐Risk Relapsed Pediatric Acute Leukemia: Real‐World Phase 1 Data Establishing the FDA‐Approved Dose

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Outcomes for pediatric relapsed/refractory (R/R) acute myeloid leukemia (AML) remain dismal. CPX‐351, a liposomal formulation of cytarabine and daunorubicin, may have less off‐target toxicities than traditional chemotherapies and has shown improved outcomes for adults with newly diagnosed therapy‐related AML.

A Proposed Stochastic Finite Difference Approach Based on Homogenous Chaos Expansion

open access: yesJournal of Applied Mathematics, 2013
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
