Sculpting Eccentric Debris Disks with Eccentric Gas Rings [PDF]

The Astrophysical Journal, 2019
Abstract Many debris disks seen in scattered light have shapes that imply their dust grains trace highly eccentric, apsidally aligned orbits. Apsidal alignment is surprising, especially for dust. Even when born from an apse-aligned ring of parent bodies, dust grains have their periastra dispersed in all directions by stellar radiation ...

Increased prefrontal activity and reduced motor cortex activity during imagined eccentric compared to concentric muscle actions

Frontiers in Human Neuroscience, 2012
In this study we used functional magnetic resonance imaging (fMRI) to examine differences in recruited brain regions during the concentric and the eccentric phase of an imagined maximum resistance training task of the elbow flexors in healthy young ...

Explosions Triggered by Violent Binary-Star Collisions: Application to Eta Carinae and other Eruptive Transients

, 2010
This paper discusses a model where a violent periastron collision of stars in an eccentric binary system induces an eruption or explosion seen as a brief transient source, attributed to LBVs, SN impostors, or other transients.

Phase-Specific Joint Mechanical Power Contribution to the Half Squat Exercise: A PBT Framework Analysis

Applied Sciences
This study investigates the joint mechanical power (JMP) distribution in the half squat (HS) exercise through the Power-Based Training (PBT) framework, with the primary aim of providing preliminary methodological validation of this analytical approach ...

Relationships between force-time curve variables and jump height during countermovement jumps in young elite volleyball players

Acta Gymnica, 2018
Background: The importance of vertical jumps has been extensively recognised in sports. Furthermore, the main indicator of success in vertical jumps is the attained height, however, there is lack of knowledge on how the eccentric and concentric force ...

Muscle fiber conduction velocity is more affected after eccentric than concentric exercise

, 2011
It has been shown that mean muscle fiber conduction velocity (CV) can be acutely impaired after eccentric exercise. However, it is not known whether this applies to other exercise modes.

The influence of general-relativity effects, dynamical tides and collisions on planet-planet scattering close to the star

, 2019
Planet--Planet scattering is an efficient and robust dynamical mechanism for producing eccentric exoplanets. Coupled to tidal interactions with the central star, it can also explain close--in giant planets on circularized and potentially misaligned ...
