Adaptive steganography based on covariance and Dct
, 2011 The steganography is a covert communication to transfer confidential information over an internet. In this paper we propose Adaptive Steganography based on Covariance and Discrete Cosine Transform (ASCDCT) algorithm.

UroPrecision, EarlyView.Abstract Background The diagnosis of prostate cancer (PCa) is limited by low specificity and invasiveness. This study aims to establish a highly accurate, noninvasive reverse transcription‐quantitative polymerase chain reaction (RT‐qPCR)‐based urinary prostate cancer antigen 3 (PCA3) assay system and explore the feasibility of using first‐morning urine

A fast method for textural analysis of DCT-based image
, 2005 The multiresolution wavelet transform is an effective procedure in texture analysis. However, many images are still compressed by the methods based on the discrete cosine transform (DCT).

Veterinary Record, EarlyView.Abstract Background Despite common concerns, evidence that anaesthesia impairs vaccine efficacy remains limited. This study assessed the impact of general anaesthesia on the immune response to rabies vaccination in cats. Methods Thirty‐five healthy female cats (6–12 months old) undergoing elective spaying were enrolled.

D‐stroi – a uniaxial load frame for X‐ray diffraction and imaging
Journal of Synchrotron Radiation, EarlyView.A remote miniature load frame for X‐ray diffraction and imaging applications is presented. The load frame has been assessed for mechanical stability and suitability for various synchrotron X‐ray‐based techniques.We present a remotely controlled miniature load frame for in situ tensile deformation of millimetre‐sized metal samples in synchrotron X‐ray ...

Calcitonin‐like diuretic hormone influences reproduction in adult female Rhodnius prolixus
Insect Science, EarlyView.Highlights • CT/DH‐like immunoreactivity is present in female reproductive tissues • CT/DH receptor transcripts are expressed in the fat body and ovaries • RNAi knockdown of CT/DH receptors reduces egg number and hatching rate • Rhopr‐CT/DH increases RhoprVg1 and RhoprVgR expression in ovaries in vitro • Rhopr‐CT/DH stimulates oviduct contractions in a

DCT/DST-based frequency modulated-OFDM
Among the recent advancements in waveform design for wireless communication, the frequency-modulated orthogonal frequency-division multiplexing (FM-OFDM) has gained attention due to its resilience to phase noise and Doppler spread, as well as its zero-dB
