Flash memories find wide use in storing data in any application. Data deletion in flash memories involves making the data unreliable on the device. As contents get deleted in the flash memory, time is consumed in deleting the data on the flash permanently. This paper proposes a method to make the contents of the deleted blocks in the flash memory unreliable. The proposed method makes data unrel...

Editorial Lown et al. (1) report a significant advance in describing a new mechanism by which ingested nutrients may change exposure to drug therapy. Grapefruit juice was reported to increase plasma concentrations of felodipine and nifedipine when the drug was concurrently administered with grapefruit juice (2). The potential clinical importance of such an interaction was noted when cyclosporin...

One of the most important problems in urological practice is how to differentiate clinically significant and non significant prostate cancer (Pca) i.e. how to avoid over treatment of tumors with low malignant potential in one hand, and inappropriate less aggressive treatment of significant tumors, on the other hand. At the first place, one should estimate precise local clinical stage and the gr...

Recently, confidence intervals (CIs) associated with parameter estimates in the susceptibleinfected-recovered epidemiological model have been developed. When model assumptions are met and the observation error is relatively small, these CIs are relatively short. This work describes the behavior of CIs for parameters as observation and/or equation or model error becomes larger, and includes a co...

This paper proposes a novel fragile watermarking scheme with a hierarchical mechanism, in which pixel-derived and block-derived watermark data are carried by the least significant bits of all pixels. On the receiver side, after identifying the blocks containing tampered content, the watermark data hidden in the rest blocks are exploited to exactly locate the tampered pixels. Moreover, using exh...

The information-hiding ratio is a well-known metric for evaluating steganalysis performance. In this paper, we introduce a new metric of image complexity to enhance the evaluation of steganalysis performance. In addition, we also present a scheme of steganalysis of least significant bit (LSB) matching steganography, based on feature mining and pattern recognition techniques. Compared to other w...

This is a Project Michelson study report. The author analyzes 17 Chinese Communist dramatic films and compares them with traditional Chinese literature and drama and with Chinese films produced in Taiwan and Hong Kong. The dominant themes discussed are 1. The Feudalistic Family 2. Liberation of Women 3. Liberation of Youth 4. Reactionary Figures 5. Revolutionary Figures 6. Antiindividualism 7. ...

Sterilization is a very popular word used in biomedical testing (like removal of all microorganisms on surface of an article or in fluid using appropriate chemical products). Motivated by this biological analogy, we, for the first time, introduce the concept of sterilization of an image, i.e., removing any steganographic information embedded in the image. Experimental results show that our tech...

Security of transferring data through channels has lots of concern especially if the transferred data is important. In stereo images, the scene is reconstructed from pair of images; the resulting is the 3D information which in some applications needs to be transferred through insecure channel. The security is important to protect the data from eavesdropping. We have proposed novel technique to ...
