DISCRETE ATOMIC COMPRESSION OF DIGITAL IMAGES
Радіоелектронні і комп'ютерні системи, 2018 The subject matter of this paper is the discrete atomic compression (DAC) of digital images, which is a lossy compression process based on the discrete atomic transform (DAT). The goal is to investigate the efficiency of the DAC algorithm.

Compressive sensing using the modified entropy functional [PDF]
Digital Signal Processing, 2014 In most compressive sensing problems, @?"1 norm is used during the signal reconstruction process. In this article, a modified version of the entropy functional is proposed to approximate the @?"1 norm. The proposed modified version of the entropy functional is continuous, differentiable and convex.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Molecular Oncology, EarlyView.Clinical trials on PARP inhibitors in urothelial carcinoma (UC) showed limited efficacy and a lack of predictive biomarkers. We propose SLFN5, SLFN11, and OAS1 as UC‐specific response predictors. We suggest Talazoparib as the better PARP inhibitor for UC than Olaparib.

Robust Steganography by Modifying Sign of DCT Coefficients
IEEE Access, 2019 Modern adaptive image steganography with minimizing a distortion function has high performance of undetectability. However, when an image with hidden information is attacked by JPEG compression, its robustness cannot be guaranteed, that remarkably limits

Molecular Oncology, EarlyView.HDAC4 is degraded by the E3 ligase FBXW7. In colorectal cancer, FBXW7 mutations prevent HDAC4 degradation, leading to oxaliplatin resistance. Forced degradation of HDAC4 using a PROTAC compound restores drug sensitivity by resetting the super‐enhancer landscape, reprogramming the epigenetic state of FBXW7‐mutated cells to resemble oxaliplatin ...

Molecular Oncology, EarlyView.Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Molecular Oncology, EarlyView.Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Lossless Compression Algorithm Based on Hybrid Coding of Adaptive Huffman and Golomb-Rice for WSN [PDF]
Jisuanji gongcheng, 2016 Aiming at the problem that traditional Wireless Sensor Network(WSN) data compression algorithms cannot take both compression efficiency and data loss into account,a fast and efficient Lossless Adaptive Compression(LAC) algorithm based on adaptive Huffman
