Dawes Review 4: Spiral Structures in Disc Galaxies [PDF]

open access: yes, 2014
The majority of astrophysics involves the study of spiral galaxies, and stars and planets within them, but how spiral arms in galaxies form and evolve is still a fundamental problem. Major progress in this field was made primarily in the 1960s, and early

The Morphological Aberrations of Cystic Duct and its Clinical Significance: A Gross Anatomical Study

open access: yesInternational Journal of Anatomy Radiology and Surgery, 2018
Introduction: The Cystic Duct (CD) serves as a thorough fare for transport of bile to and away from the gallbladder. It is about 2-4 cm in length and 1-5 mm in diameter, and joins the Common Hepatic Duct (CHD) at its right lateral aspect, in the ...

Minimal Fat Content in Papillary Renal Cell Carcinoma Diagnosed with Dual-Layer Dual-Energy CT

open access: yesDiagnostics, 2023
A 56-year-old man with a previous right nephrectomy for multiple papillary renal cell carcinomas (pRCC) underwent a follow-up CT scan. Using a dual-layer dual-energy CT (dlDECT), we demonstrated the presence of a small amount of fat in a 2.5 cm pRCC that

Spiral wave chimeras in locally coupled oscillator systems [PDF]

open access: yes, 2015
The recently discovered chimera state involves the coexistence of synchronized and desynchronized states for a group of identical oscillators. This fascinating chimera state has until now been found only in non-local or globally coupled oscillator ...

Magnetic Field Vector Structure of NGC6946

open access: yesGalaxies, 2019
We studied large-scale magnetic field reversals of a galaxy based on a magnetic vector map of NGC6946. The magnetic vector map was constructed based on the polarization maps in the C and X bands after the determination of the geometrical orientation of a

Spiral spin-liquid and the emergence of a vortex-like state in MnSc$_2$S$_4$

open access: yes, 2016
Spirals and helices are common motifs of long-range order in magnetic solids, and they may also be organized into more complex emergent structures such as magnetic skyrmions and vortices. A new type of spiral state, the spiral spin-liquid, in which spins
