Entropy and Its Correlations with Other Related Quantities

open access: yesEntropy, 2014
In order to find more correlations between entropy and other related quantities, an analogical analysis is conducted between thermal science and other branches of physics. Potential energy in various forms is the product of a conserved extensive quantity

Potential energy surfaces for cluster emitting nuclei [PDF]

open access: yes, 2005
Potential energy surfaces are calculated by using the most advanced asymmetric two-center shell model allowing to obtain shell and pairing corrections which are added to the Yukawa-plus-exponential model deformation energy.

Dynamic Analysis of Planetary Gear with Root Crack in Sun Gear Based on Improved Time-Varying Mesh Stiffness

open access: yesApplied Sciences, 2020
The time-varying mesh stiffness (TVMS) is the crucial parameter of the dynamic model of the gear system. Accurate calculation of TVMS is essential for effective fault diagnosis of the gear system.

Stretching the Inflaton Potential with Kinetic Energy [PDF]

open access: yes, 2007
Inflation near a maximum of the potential is studied when non-local derivative operators are included in the inflaton Lagrangian. Such terms can impose additional sources of friction on the field. For an arbitrary spacetime geometry, these effects can be

In silico analysis of wild-type and mutant KRAS [PDF]

open access: yesPharmaciana, 2019
The mutations of the KRAS gene at codons 12, 13, and 61 have been widely reported with different prognosis. In silico is one approach to explain the characteristics of the mutant genes.

The Long Range Gravitational Potential Energy Between Strings [PDF]

open access: yes, 2001
We calculate the gravitational potential energy between infinitely long parallel strings with tensions \tau_1 and \tau_2. Classically, it vanishes, but at one loop, we find that the long range gravitational potential energy per unit length is U/L = 24G_N^
