Weighted Opposition-Based Fuzzy Thresholding [PDF]
, 2011 With the rapid growth of the digital imaging, image processing techniques are widely involved in many industrial and medical applications. Image thresholding plays an essential role in image processing and computer vision applications.

Segmentation of bone structures in Magnetic Resonance Images (MRI) for human hand skeletal kinematics modelling [PDF]
, 2011 Roboticists have shown a great interest in designing and building robotic hands, mainly because of the complex structure and high range of functionalities that the human hand has.

CEACAM1 participation in breast cancer progression
Molecular Oncology, EarlyView.In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

Multilevel thresholding based on mean shift mode seeking
, 2011 A novel multilevel thresholding method based on mean shift procedure is proposed to resolve the problem that the optimal number of thresholds for multilevel thresholding can usually not be predetermined.

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer
Molecular Oncology, EarlyView.Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

Molecular Oncology, EarlyView.Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

Blind white denoising of speech signals
Visión Electrónica, 2012 Discrete Wavelet Transform (DWT) has been used in the recent years in signal processing applications, i.e. filtering and compression. In the case of denoising because the energy of the noise is spread in the entire wavelet coefficients and it has low ...

Adaptive Wavelet Estimation: A Block Thresholding And Oracle Inequality Approach
, 1998 We study wavelet function estimation via the approach of block thresholding and ideal adaptation with oracle. Oracle inequalities are derived to offer insights into the balance and tradeoff between block size and threshold level.

Molecular Oncology, EarlyView.We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...
