Nowadays, image steganography has an important role in hiding information in advanced applications, such as medical image communication, confidential communication and secret data storing, protection of data alteration, access control system for digital content distribution and media database systems. In these applications, one of the most important aspects is to hide information in a cover image whithout suffering any alteration. Currently, all existing approaches used to hide a secret message in a cover image produce some level of distortion in this image.

Article Synopsis
  • Human action recognition is increasingly important in healthcare and other fields, with various algorithms developed over the last decade to improve detection and recognition efficiency using advanced computing.
  • However, real-time applications face challenges such as camera movement and complex scenes, often overwhelming current computer systems.
  • To address this, a new approach inspired by human visual perception—specifically selective visual attention—utilizes a spiking neural P system for efficient feature extraction, achieving over 97% performance improvement in low-computational complexity neural classifiers for action recognition.

The purpose of this study was to assess the effect of the non-selective cholecystokinin receptor antagonist proglumide on the antinociceptive activity of ketorolac and meloxicam in non-diabetic and diabetic rats. Streptozotocin (60 mg/kg) injection caused hyperglycemia which was maintained for 2 weeks. Formalin-evoked flinching was increased in diabetic rats as compared to non-diabetic rats.

In this article, we consider the intersection of religious coping and the experience of Hurricanes Katrina and Rita in a lifespan sample of adults living in South Louisiana during the 2005 storms. Participants were young, middle-age, older, and oldest-old adults who were interviewed during the post-disaster recovery period. Qualitative analyses confirmed that three dimensions of religion were represented across participants' responses.
