Toward Understanding the Evolutionary Role of Star-forming Lenticular Galaxies: New H i Detections and Comparison with Quiescent S0s and Red Spirals

open access: yesThe Astrophysical Journal
As one type of blue early-type galaxy, the evolutionary history and fate of star-forming lenticular galaxies (S0s) remain elusive. We selected 134 star-forming S0s from the Sloan Digital Sky Survey IV MaNGA survey and found that they have steep and ...

Shrinkage Points of Golden Rectangle, Fibonacci Spirals, and Golden Spirals

open access: yesDiscrete Dynamics in Nature and Society, 2019
We investigated the golden rectangle and the related Fibonacci spiral and golden spiral. The coordinates of the shrinkage points of a golden rectangle were derived. Properties of shrinkage points were discussed.

Spiral inflation

open access: yesPhysics Letters B, 2015
We propose a novel scenario of primordial inflation in which the inflaton goes through a spiral motion starting from around the top of a symmetry breaking potential. We show that, even though inflation takes place for a field value much smaller than Planck scale, it is possible to obtain relatively large tensor to scalar ratio ($r \sim 0.1$) without ...

Automated FRAP microscopy for high‐throughput analysis of protein dynamics in chromatin organization and transcription

open access: yesFEBS Open Bio, EarlyView.
RoboMic is an automated confocal microscopy pipeline for high‐throughput functional imaging in living cells. Demonstrated with fluorescence recovery after photobleaching (FRAP), it integrates AI‐driven nuclear segmentation, ROI selection, bleaching, and analysis.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Spiraled Origins [PDF]

open access: yesMolecular Cell, 2005
Recent studies have established that the eukaryotic actin-based cytoskeleton has prokaryotic origins. In addition to regulating cell shape and polarity, Gitai et al. (2005) provide convincing evidence that the Caulobacter actin homolog MreB also mediates the early segregation of the chromosomal origin, a typical functional role of the eukaryotic ...

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Why Are Some Optically Red Spirals Near-ultraviolet− r Blue?

open access: yesThe Astrophysical Journal
To understand the complicated formation processes of disk galaxies, we carry out a comparative study of near-ultraviolet (NUV)− r blue and red spiral galaxies drawn from a parent sample of u−r red spirals with M _*  > 10 ^10.5 M _⊙ at 0.02

Spiral flames

open access: yesApplied Mathematics Letters, 2003
This short paper is to describe computations of periodic and meandering spiral patterns in a reaction-diffusion model of flames, regarding the existence of spiral structures and their evolution as functions of the parameters which are representatives of combustion.
