Trace Concealment Histogram-Shifting-Based Reversible Data Hiding with Improved Skipping Embedding and High-Precision Edge Predictor (ChinaMFS 2022)

Mathematics, 2022
Reversible data hiding (RDH) is a special class of steganography, in which the cover image can be perfectly recovered upon the extraction of the secret data. However, most image-based RDH schemes focus on improving capacity–distortion performance.

Reversible Data Hiding with a New Local Contrast Enhancement Approach

Mathematics, 2022
Reversible data hiding schemes hide information into a digital image and simultaneously increase its contrast. The improvements of the different approaches aim to increase the capacity, contrast, and quality of the image.

scikit-hep/boost-histogram: Version 1.0.0

, 2021
Dropped support for Python 2 and 3.5; removed large numbers of workarounds. Fully statically typed. API compatible with the final 0.x release for most uses, except for subclassing; subclassing histogram components now uses Python 3 class keyword syntax ...

Reversible Information Hiding Algorithm in Encrypted Domain Based on Difference Histogram Shifting [PDF]

Jisuanji gongcheng, 2019
The embedding capacity of the current difference histogram shifting algorithm is low.To cope with this problem,we propose a large-capacity reversible data hiding algorithm in encrypted domain.First,we use the single homomorphic encryption to enable a ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Stimulator of interferon genes agonist augmented antitumor immunity of osimertinib in Egfr‐mutated lung cancer

Molecular Oncology, EarlyView.
Combining osimertinib with the STING agonist ADU‐S100 activates innate and adaptive immunity to overcome the non‐inflamed microenvironment of Egfr‐mutant lung cancer. This combination increases NK and CD8+ T‐cell infiltration, associated with activation of the STING‐IRF3 pathway and local immunogenic cell death.
