Medical Image Watermarking Technique for Accurate Tamper Detection in ROI and Exact Recovery of ROI

International Journal of Telemedicine and Applications, 2014
In telemedicine while transferring medical images tampers may be introduced. Before making any diagnostic decisions, the integrity of region of interest (ROI) of the received medical image must be verified to avoid misdiagnosis. In this paper, we propose

Mode‐of‐Action and Human Relevance Assessment for Diisononyl Phthalate‐Induced Liver Tumors in Rodents

Journal of Applied Toxicology, EarlyView.
ABSTRACT Diisononyl phthalate (DINP) is a high molecular weight phthalate and high production volume chemical. DINP's carcinogenic potential has been investigated in four rodent bioassays, with liver tumors observed in three of the studies. Authoritative assessments have hypothesized that DINP acts through the peroxisome proliferator‐activated receptor

Hybrid fragile image watermarking for tamper detection, localization and dual self-recovery

Engineering Science and Technology, an International Journal
This paper presents a novel image watermarking framework that effectively addresses the issue of random block mapping. This phenomenon compromises tampered regions and their corresponding recovery blocks, resulting in irretrievable image data.

Peri‐implant disease pathogenesis animal models: Consensus report of Workgroup 1 of the IADR Implantology Research Group Best Evidence Consensus Symposium on Peri‐Implant Disease and Its Treatment

Journal of Periodontology, EarlyView.
Abstract Background The pathogenesis and etiology of peri‐implantitis demand a deeper understanding to lead to successful treatment modalities. Animal models of peri‐implantitis pathogenesis offer unique insights but their translational impact requires consideration of implant biomaterials science.

Block Based Medical Image Watermarking Technique for Tamper Detection and Recovery

CoRR, 2014
In this paper, we propose a novel fragile block based medical image watermarking technique for embedding data of patient into medical image, verifying the integrity of ROI (Region of Interest), detecting the tampered blocks inside ROI and recovering original ROI with less size authentication and recovery data and with simple mathematical calculations ...

Sewage Sludge and Cashew Bagasse Biochars Promote Changes in Selected Physical Attributes Related to the Structure of Degraded Dryland Soil

Journal of Plant Nutrition and Soil Science, EarlyView.
This study evaluated biochars from co‐pyrolysis of sewage sludge and cashew residues on physical quality of a degraded loamy sand soil. SPB applied at 20 Mg ha−1 reduced bulk density by 7.74%, whereas most porosity attributes were driven by soil reconsolidation rather than biochar. Aggregate stability varied with biochar type, with SPB promoting larger

Foraging and movement flexibility shape seed dispersal by an arboreal primate in a modified landscape

Oikos, EarlyView.
As habitats change, the effectiveness of animal‐mediated seed dispersal increasingly depends on animal responses to altered structure and resources. With habitat loss and degradation accelerating across the tropics, understanding how dispersers' foraging behavior and movement influence seed removal and deposition is critical to promoting forest ...

Ciphertext-domain fragile watermarking using hamming codes for dual-stage tamper detection and recovery

Journal of King Saud University: Computer and Information Sciences
Cloud storage greatly facilitates large-scale image hosting but also exposes encrypted content to the risk of visually plausible ciphertext-domain tampering after decryption.
