Secure gray image sharing framework with adaptive key generation using image digest.

In the constantly changing digital age where instant information sharing is shared globally, the content's safe delivery and privacy management have become necessary. Mainly, information in multimedia data becomes massive in networks, and sharing such data becomes vital and vulnerable. To mitigate the vulnerability in information sharing over public networks, it is crucial to develop privacy-preserving algorithms and system security schemes that ensure the safety, ownership and integrity of the information that travels through the network.

Reconfigurable security solution based on hopfield neural network for e-healthcare applications.

In the healthcare sector, e-diagnosis through medical images is essential in a multi-speciality hospital; securing the medical images becomes crucial for preserving an individual's privacy in e-healthcare applications. So, this paper has proposed a novel encryption scheme implemented on reconfigurable hardware. Realising image encryption schemes on FPGA hardware platforms offers substantial advantages over software implementations.

Hubs and Bottlenecks in Protein-Protein Interaction Networks.

Protein-protein interaction networks (PPINs) represent the physical interactions among proteins in a cell. These interactions are critical in all cellular processes, including signal transduction, metabolic regulation, and gene expression. In PPINs, centrality measures are widely used to identify the most critical nodes.

Dissection of hubs and bottlenecks in a protein-protein interaction network.

Analysis of degree centrality in conjunction with betweenness centrality of proteins in a human protein-protein interaction network revealed three categories of centrally important proteins: a) proteins with high degree and betweenness (hub-bottlenecks denoted as MX), b) proteins with high betweenness and low degree (non-hub-bottlenecks/pure bottlenecks denoted as PB) and c) proteins with high degree and low betweenness (hub-non-bottlenecks/pure hubs denoted as PH). When subjected to a detailed statistical analysis of their molecular-level properties, the proteins belonging to each of these categories were found to be associated with distinct canonical molecular properties, i.e.

Synergistic antimicrobial combination of carvacrol and thymol impairs single and mixed-species biofilms of and .

and are important opportunistic human pathogens, which form mixed-species biofilms and cause recalcitrant device associated infections in clinical settings. Further to many reports suggesting the therapeutic potential of plant-derived monoterpenoids, this study investigated the interaction of the monoterpenoids carvacrol (C) and thymol (T) against mono- and mixed-species growth of and . C and T exhibited synergistic antimicrobial activity.
