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.

The Image Characteristics for Perceived Naturalness
i-Perception, 2011 To identify the visual characteristics that make a scene looks nature, we investigated the relationship between the distribution of spatial frequency spectrum of an image and its perceived naturalness.

A short feature vector for image matching: The Log-Polar Magnitude feature descriptor. [PDF]
PLoS ONE, 2017 The choice of an optimal feature detector-descriptor combination for image matching often depends on the application and the image type. In this paper, we propose the Log-Polar Magnitude feature descriptor-a rotation, scale, and illumination invariant ...

Unpaired Image-to-Image Translation to Improve Log End Identification
ESANN 2024 proceesdingsVisual re-identification tasks are often subject to large domain variations due to camera types, brightness conditions, or environmental differences. For identification models to generalize in such varying domains, a large amount of training data is necessary for capturing these variations.

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).

Interest Point Detection by Limiting Form of Median Log Filter
IEEE Access, 2019 Interest point detection has been widely used in image analysis applications. However, some interest points, including small structures and large angle corners, could not be effectively extracted.

Disparity Estimation on Log-Polar Images and Vergence Control [PDF]
Computer Vision and Image Understanding, 2001 Summary: An important issue in the realization of an autonomous robot with stereoscopic vision is the control of vergence. Together with version, it determines uniquely the position of the fixation point in space. Vergence control is directly related to both depth perception and binocular fusion.

Molecular Oncology, EarlyView.This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).
