RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells

FEBS Open Bio, EarlyView.
RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...

Distortions of the discrete frequency-keyed signals with the linear frequency-modulated impulses in the antenna array

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019
Singularities of influence of distortions caused by object rotation, change of its sizes and nonlinearity of transceiver paths of the antenna array on results of handling of the discrete is frequency-keyed signals in broad-band radar-tracking systems of ...

Minimum Spectral Bandwidth in Echo Seeded Free Electron Lasers

Frontiers in Physics, 2019
This paper examines the impact of non-linear longitudinal phase distortions on the spectral bandwidth in echo seeded free electron lasers (FELs). It extends the existing theory developed in Hemsing [1] for echo-enabled harmonic generation (EEHG) to ...

Generalized linear mixed model for segregation distortion analysis [PDF]

BMC Genetics, 2011
Segregation distortion is a phenomenon that the observed genotypic frequencies of a locus fall outside the expected Mendelian segregation ratio. The main cause of segregation distortion is viability selection on linked marker loci. These viability selection loci can be mapped using genome-wide marker information.We developed a generalized linear mixed ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

From redshift to real space: Combining linear theory with neural networks

Astronomy & Astrophysics
Context. Spectroscopic redshift surveys are key to tracing the large-scale structure (LSS) of the Universe and testing the Λ Cold Dark Matter model. However, redshifts as distance proxies introduce distortions in the 3D galaxy distribution.

Guiding AlphaFold to predict how Munc13‐1 opens Syntaxin‐1

FEBS Open Bio, EarlyView.
The syntaxin‐1 Habc‐domain (orange), linker (pink) and SNARE motif (yellow) form a closed conformation that binds to Munc18‐1 (violet) and is opened by the Munc13‐1 MUN domain (cyan) to form the SNARE complex that triggers neurotransmitter release.

A Robust Ground‐to‐Image Transformation Algorithm and Its Applications in the Geometric Processing of Linear Pushbroom Images

Earth and Space Science, 2019
Linear array cameras are widely used in the fields of aerial and space remote sensing. The ground‐to‐image transformation plays a significant role in the geometric processing procedures of linear pushbroom images, which is time‐consuming due to multiple ...

A non-linear controller design for UPQC in distribution systems

Alexandria Engineering Journal, 2018
In this article, a new approach based on non-linear control scheme was proposed for unified power quality conditioner (UPQC). The combination of sliding mode control and instantaneous active and reactive power theories was used to design this controller.

Measurement of intermodulation distortion in high-linearity photodiodes

Optics Express, 2010
Accurately characterizing third order intermodulation distortion (IMD3) in high-linearity photodiodes is challenging. Two measurement techniques are evaluated-a standard two-tone measurement and a more complicated three-tone measurement technique to measure IMD3.
