A novel and efficient digital image steganography technique using least significant bit substitution.

Steganography is used to hide sensitive types of data including images, audio, text, and videos in an invisible way so that no one can detect it. Image-based steganography is a technique that uses images as a cover media for hiding and transmitting sensitive information over the internet. However, image-based steganography is a challenging task due to transparency, security, computational efficiency, tamper protection, payload, etc.

Altered post-fracture systemic bone loss in a mouse model of osteocyte dysfunction.

Femur fracture leads to loss of bone at uninjured skeletal sites, which may increase risk of subsequent fracture. Osteocytes, the most abundant bone cells, can directly resorb bone matrix and regulate osteoclast and osteoblast activity, but their role in systemic bone loss after fracture remains poorly understood. In this study we used a transgenic (TG+) mouse model that overexpresses human B-cell lymphoma 2 (BCL-2) in osteoblasts and osteocytes.

Assessment of Medication Adherence Using Mobile Applications in Chronic Obstructive Pulmonary Disease: A Scoping Review.

Chronic obstructive pulmonary disease (COPD) is a condition that significantly impacts both patients and healthcare systems. The management of COPD involves various pharmacological intervention strategies, and addressing the issue of low adherence to these strategies has become a subject of significant interest. In response to this concern, there has been a shift toward utilizing telemedicine and mobile applications.

k* Distribution: Evaluating the Latent Space of Deep Neural Networks Using Local Neighborhood Analysis.

Most examinations of neural networks' learned latent spaces typically employ dimensionality reduction techniques such as t-distributed stochastic neighbor embedding (t-SNE) or uniform manifold approximation and projection (UMAP). These methods distort the local neighborhood in the visualization, making it hard to distinguish the structure of a subset of samples in the latent space. In response to this challenge, we introduce the k* distribution and its corresponding visualization technique.

Brief intervention protocol by telephone delivered by nurses to patients with harmful alcohol use in primary health care: A feasibility trial.

Aim: The aim of this study is to examine the feasibility of a brief intervention protocol by telephone performed by nurses in primary health care facilities.

Methods: A nonrandomized single-arm feasibility study was performed. The proposed intervention of this study is the Brief Intervention carried out by the nurse delivered by telephone, synchronously with alcohol users.
