Greedy Pairing Prediction-error Expansion for Reversible Data Hiding

DEStech Transactions on Materials Science and Engineering, 2017
Reversible data hiding (RDH) is a method to embed messages in an image that human eyes are difficult to recognize the differences between the original image and the embedded image. But the method has to make sure that the original image and the embedded information can be exactly recovered.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

An Improved Image Camouflage Technique Using Color Difference Channel Transformation and Optimal Prediction-Error Expansion

IEEE Access, 2018
With the development of the ability to crack encrypted images, conventional image encryption techniques are no longer safe enough. Disguising a to-be-encrypted image into another visually-different image that is similar to the prepared target image is a ...

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

FEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Reversible Data Hiding for Encrypted 3D Model Based on Prediction Error Expansion

Journal of Sensors, 2020
Since 3D models can intuitively display real-world information, there are potential scenarios in many application fields, such as architectural models and medical organ models. However, a 3D model shared through the internet can be easily obtained by an unauthorized user.

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Reversible Text Watermarking Algorithm Using Prediction-error Expansion Method [PDF]

Proceedings of the International Conference on Computer, Networks and Communication Engineering (ICCNCE 2013), 2013
In order to avoid the permanent change of the text content caused by watermark embedding, this paper proposes a reversible watermarking algorithm for Chinese text document using prediction-error expansion. The algorithm takes the sentence as the unit, through the context collocation degree to select the words that can be replaced, using prediction ...
