FEBS Open Bio, EarlyView.In this study, we developed a deep learning method for mitotic figure counting in H&E‐stained whole‐slide images and evaluated its prognostic impact in 13 external validation cohorts from seven different cancer types. Patients with more mitotic figures per mm2 had significantly worse patient outcome in all the studied cancer types except colorectal ...

Comparison Of Reversible Image Watermarking Methods Based On Prediction-Errors
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019 This study compares two reversible imagewatermarking algorithms applied to a digital image. The first algorithm is amethod based on adaptive watermarking of prediction-errors.

FEBS Open Bio, EarlyView.Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

A High-Capacity Reversible Watermarking Technique Using Bit-Level Expansion and Pixel Shifting
Communications in Science and TechnologyThis paper proposes a high-capacity reversible watermarking method using adaptive bit-level expansion and pixel-class-guided shifting. Pixels are classified into expandable (P0) and non-expandable (P1) according to their 2-bit LSB patterns, and a ...

A New Bi-Level Encoding and Decoding Scheme for Pixel Expansion Based Visual Cryptography
, 2019 Mapping of image-based object textures to ASCII characters can be a new modification towards visual cryptography. Naor and Shamir proposed a new dimension of Information security as visual cryptography which is a secret sharing scheme among N number of ...

FEBS Open Bio, EarlyView.Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

DMD-based diffractive FOV expansion for real-time flash lidar with 2D multi-pixel photon counter
, 2022 We demonstrated a real-time lidar system that utilizes a Digital Micromirror Device (DMD) as a field of view (FOV) expander and a 2D Multi-Pixel Photon Counter (MPPC) as a lidar sensor.

FEBS Open Bio, EarlyView.Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...
