A New Algorithm for 2-D Transport for Astrophysical Simulations: I. General Formulation and Tests for the 1-D Spherical Case [PDF]

open access: yes, 2006
We derive new equations using the mixed-frame approach for one- and two-dimensional (axisymmetric) time-dependent radiation transport and the associated couplings with matter.

Radiation 'damping' in atomic photonic crystals [PDF]

open access: yes, 2010
The force exerted on a material by an incident beam of light is dependent upon the material's velocity in the laboratory frame of reference. This velocity dependence is known to be diffcult to measure, as it is proportional to the incident optical power ...

Phase Separation and Neurodegenerative Diseases: A Disturbance in the Force.

open access: yesDevelopmental Cell, 2020
Protein aggregation is the main hallmark of neurodegenerative diseases. Many proteins found in pathological inclusions are known to undergo liquid-liquid phase separation, a reversible process of molecular self-assembly.

Four-nucleon force contribution to the binding energy of 4He

open access: yesEPJ Web of Conferences, 2010
We study the four-nucleon force contribution to the binding energy of 4He in the framework of chiral nuclear interactions. The four-nucleon forces start to contribute in the next-to-next-to-next-to leading order.

Analyzing false positives of four questions in the Force Concept Inventory

open access: yesPhysical Review Physics Education Research, 2018
In this study, we analyze the systematic error from false positives of the Force Concept Inventory (FCI). We compare the systematic errors of question 6 (Q.6), Q.7, and Q.16, for which clearly erroneous reasoning has been found, with Q.5, for which ...

Effects of varying force levels and combinations of force application and release during an isometric pinch force task [PDF]

open access: yes, 2017
Fine motor control is important for the completion of many activities of daily living, such as writing, eating, buttoning a shirt, and texting. All these tasks require a high amount of continuous coordination and regulation of increasing and decreasing ...
