, 2015 We study the impact of possible spiral-arm distributions of Galactic cosmic-ray sources on the flux of various cosmic-ray nuclei throughout our Galaxy. We investigate model cosmic-ray spectra at the nominal position of the sun and at different positions ...

Thermotolerant class A acid phosphatase active across broad pH range and diverse substrates
Protein Science, Volume 34, Issue 9, September 2025.Abstract M2‐32 is a non‐specific acid phosphatase with a rare ability to function across a broad pH range (3.5–8.5). Analysis using SWISS‐PROT Prf Profiles classifies it as a class A acid phosphatase (Z‐score: 78.97), sharing 50%–60% sequence similarity with enzymes such as PhoC and PhoN.

THE ELLIPTICITIES OF GALAXIES IN GALAXY CLUSTERS OF DIFFERENT MORPHOLOGICAL TYPE
Odessa Astronomical Publications, 2014 The distribution of galaxy ellipticities was analyzed for 207 rich PF galaxy clusters found in the Munster Red Sky Survey Galaxy Catalogue. Clusters with BM types from a comparison with the ACO catalogue were also classified on the new scheme.

Spirality: A Novel Way to Measure Spiral Arm Pitch Angle
, 2016 We present the MATLAB code Spirality, a novel method for measuring spiral arm pitch angles by fitting galaxy images to spiral templates of known pitch. Computation time is typically on the order of 2 minutes per galaxy, assuming at least 8 GB of working ...

A Role for the Plastidial GPT2 Translocator in the Modulation of Lignin Biosynthesis
Plant, Cell &Environment, Volume 48, Issue 9, Page 6458-6472, September 2025.ABSTRACT Engineering plants with reduced lignin content can result in pleiotropic growth defects. In stems of Arabidopsis plants with reduced expression of hydroxycinnamoyl CoA: shikimate hydroxycinnamoyl transferase (HCT), the plastidial glucose 6‐phosphate: phosphate co‐transporter GPT2 is highly overexpressed, and this coincides with reduced lignin ...

Revealing the Bifurcations of the Milky Way Spiral Arms Based on Hi-GAL and ATLASGAL Clumps
The Astronomical JournalThe spiral structure of the Milky Way remains under debate. Y. Xu et al. proposed, for the first time, a multiple-arm morphology for our Galaxy, with two spiral arms in the inner disk bifurcating outward alongside additional independent arms in the outer

Magnetic-Field Vector Maps of Nearby Spiral Galaxies
Galaxies, 2019 We present a method for determining the directions of magnetic-field vectors in a spiral galaxy using two synchrotron polarization maps, an optical image, and a velocity field.

THE OPACITY OF SPIRAL GALAXY DISKS [PDF]
, 2007 The opacity of foreground spiral disks can be probed from the number of distant galaxies seen through them. To calibrate this number for effects other than the dust extinction, Gonzalez et al. (1998) developed the "Synthetic Field Method". A synthetic field is an extincted Hubble Deep Field added to the science field.

Surface Photometry of Spiral Galaxy NGC 5005 and Elliptical Galaxy NGC 4278
مجلة بغداد للعلوم, 2018 Two galaxies have been chosen, spiral galaxy NGC 5005 and elliptical galaxy NGC 4278 to study their photometric properties by using surface photometric techniques with griz-Filters. Observations are obtained from the Sloan Digital Sky Survey (SDSS).
