The Primordial Origin Model of Magnetic Fields in Spiral Galaxies
, 2010 We propose a primordial-origin model for the composite configurations of global magnetic fields in spiral galaxies. We show that uniform tilted magnetic field wound up into a rotating disk galaxy can evolve into composite magnetic configurations ...

Somato‐Cognitive Action Network in Focal Dystonia
Movement Disorders, Volume 40, Issue 11, Page 2331-2343, November 2025.Abstract Background The central pathology causing idiopathic focal dystonia remains unclear. The recently identified somato‐cognitive action network (SCAN) has been implicated. Objective We tested whether the effector‐agnostic SCAN may constitute a central pathology shared across dystonia subtypes, whereas the effector‐specific regions in the primary ...

Spiral structure in external galaxies [PDF]
Symposium - International Astronomical Union, 1970 The need for observing at least four different categories of optical objects for a satisfactory definition of optical spiral structure is emphasized. A sequence of optical form-types for the description of spiral structure is outlined. A pronounced difference in the nature of the spiral structure of the outer and inner parts of Messier 33 is ...

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 ...

, 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 ...

Synergies in Self‐Assembly—From Supramolecular Polymers to Defined Hierarchical Superstructures
Journal of Polymer Science, Volume 63, Issue 21, Page 4450-4465, 1 November 2025.Shaping supramolecular polymers built from molecular building blocks into superstructures with defined dimensions. Synergies within supramolecular architectures such as chirality or an additional second orthogonal driving force that does not interfere with the central supramolecular motif facilitate the confinement of the growth of these ...

Proton‐linked effects on the axial coordination in ferric and ferrous horse heart cytochrome c
Protein Science, Volume 34, Issue 11, November 2025.Abstract The effect of pH (between pH 7.0 and 0.0) on the spectroscopic properties of ferric and ferrous derivatives of horse heart cytochrome c (hhcytc‐Fe(III) and hhcytc‐Fe(II), respectively) in 1.0M phosphate buffer is reported. This study further deepens the investigation of spectroscopic properties of a heme‐protein to very low pH (i.e., pH ≈ 0 ...

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

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.

Polarimetric Observations of Spiral Galaxies
Publications of the Astronomical Society of the Pacific, 1967 The extragalactic systems NCC 3031, NCC 4594, NGC 5194, and NGC 5457 have been observed polarimetrically. Linear polarization between 0.1 and 1.0 percent was detected in the spiral arms of all four galaxies. The planes of vibration indicate that reflection as well as interstellar absorption of starlight by the internal dust clouds of the observed ...
