Resonantly Forced Eccentric Ringlets: Relationships Between Surface Density, Resonance Location, Eccentricity And Eccentricity-Gradient

open access: yesCelestial Mechanics and Dynamical Astronomy, 2005
We use a simple model of the dynamics of a narrow-eccentric ring, to put some constraints on some of the observable properties of the real systems.In this work we concentrate on the case of the `Titan ringlet of Saturn'.Our approach is fluid-like, since our description is based on normal modes of oscillation rather than in individual particle orbits ...

Why is the Moon synchronously rotating?

open access: yes, 2013
If the Moon's spin evolved from faster prograde rates, it could have been captured into a higher spin-orbit resonance than the current 1:1 resonance. At the current value of orbital eccentricity, the probability of capture into the 3:2 resonance is as ...

Age and gender effects on echocardiographic and histopathological cardiac phenotypes in healthy adult mice

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This study investigated the impact of age and sex on cardiac phenotypes in healthy adult C57BL/6J mice using echocardiography and histopathological analyses. Findings revealed that female mice demonstrated more pronounced global cardiac chamber dilation during aging.

The Imagery of M.V. Dobuzhinsky’s Illustrations to Yu.K. Olesha’s The Three Fat Men [PDF]

open access: yesХудожественная культура
Mstislav Dobuzhinsky’s illustrations to the tale by Yury Olesha The Three Fat Men have not received a convincing interpretation. It is suggested to read these illustrations as a special work with the social imaginary that expands the participation of the

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

open access: yesThe Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Study on the Influence of the Structural Asymmetry on the Torsional Response

open access: yesBulletin of the Polytechnic Institute of Jassy: Constructions, Architechture Section, 2009
For the composition and the structural design to lateral loads, the distribution of horizontal lateral forces on vertical structural elements is an important issue, which can become complicated, depending on the considered structural system.

Eccentric sequences and eccentric sets in graphs

open access: yesDiscrete Mathematics, 1976
AbstractBy a graph we mean a finite undirected connected graph of order p, p ⩾ 2, with no loops or multiple edges. A finite non-decreasing sequence S: s1, s2, …, sp, p ⩾ 2, of positive integers is an eccentric sequence if there exists a graph G with vertex set V(G) = {v1, v2, …, vp} such that for each i, 1 ⩽ i ⩽ p, s, is the eccentricity of v1. A set S

Unraveling ovarian histology: The key morphological aspects that spur the development of the Fossa ovarii in equine

open access: yesThe Anatomical Record, EarlyView.
Abstract The equine ovary exhibits unique structural and developmental features that distinguish it from those of other domestic species, including the presence of an ovulation fossa and an inversion of cortical and medullary layers. This study aimed to investigate the morphostructural development of the equine fetal ovary, with particular emphasis on ...
