FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Large Aerial Image Tie Point Matching in Real and Difficult Survey Areas via Deep Learning Method
Remote Sensing, 2022 Image tie point matching is an essential task in real aerial photogrammetry, especially for model tie points. In current photogrammetry production, SIFT is still the main matching algorithm because of the high robustness for most aerial image tie points ...

MAP inference via Block-Coordinate Frank-Wolfe Algorithm
, 2019 We present a new proximal bundle method for Maximum-A-Posteriori (MAP) inference in structured energy minimization problems. The method optimizes a Lagrangean relaxation of the original energy minimization problem using a multi plane block-coordinate ...

Perturbed block orthogonal matching pursuit
Electronics Letters, 2018 The block orthogonal matching pursuit (BOMP) algorithm is an efficient method in compressed sensing (CS) for the reconstruction of block‐sparse signals, whose non‐zero entries occur in clusters. However, due to the non‐ideal factors in practice, there exits perturbation in the CS system, which may cause significant performance degradation during ...

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

A Complexity and Quality Evaluation of Block Based Motion Estimation Algorithms
Acta Polytechnica, 2005 Motion estimation is a method, by which temporal redundancies are reduced, which is an important aspect of video compression algorithms. In this paper we present a comparison among some of the well-known block based motion estimation algorithms.

Block matching in rotated images
Electronics Letters, 2005 A rotationally invariant block-matching algorithm for matching point features in rotated images is presented. The algorithm matches the detected point features by extracting a small image area (block) centred on each point in the first image and searching for a highly similar block in the second image.
