A transfer function approach to reaction rate analysis with applications to phase-change materials and devices [PDF]

open access: yes, 2013
A very good approximate, closed-form solution to the reaction rate equation with Arrhenius temperature dependence is derived, valid for activation energies E >> kBxT0 (kB is Boltzmann constant and T0 is room temperature) and monotonically decreasing ...

Aspects of ultra-relativistic field theories via flat-space holography

open access: yesPhysics Letters B, 2017
Recently it was proposed that asymptotically flat spacetimes have a holographic dual which is an ultra-relativistic conformal field theory. In this paper, we obtain the conformal anomaly for such a theory via the flat-space holography technique ...

Experimental study and weighting analysis of factors influencing gas desorption

open access: yesFrontiers in Earth Science, 2023
Gas is one of the necessary contributing factors for coal and gas outburst accidents, and the gas desorbed in coal is the energy carrier in the outburst process.

A DIRECT MEASUREMENT OF THE BARYONIC MASS FUNCTION OF GALAXIES AND IMPLICATIONS FOR THE GALACTIC BARYON FRACTION [PDF]

open access: yes, 2012
We use both an H i-selected and an optically selected galaxy sample to directly measure the abundance of galaxies as a function of their “baryonic” mass (stars + atomic gas).

Decreasing and complete monotonicity of functions defined by derivatives of completely monotonic function involving trigamma function

open access: yesDemonstratio Mathematica
Abstract In this study, using convolution theorem of the Laplace transforms, a monotonicity rule for the ratio of two Laplace transforms, Bernstein’s theorem for completely monotonic functions, and other analytic techniques, the authors verify decreasing property of a ratio between three derivatives of a function involving trigamma ...

Resource Competition Shapes the Response of Genetic Circuits

open access: yesbioRxiv, 2017
A common approach to design genetic circuits is to compose gene expression cassettes together. While appealing, this modular approach is challenged by the fact that expression of each gene depends on the availability of transcriptional/translational ...

Non-monotonic effects of GABAergic synaptic inputs on neuronal firing.

open access: yesPLoS Computational Biology, 2022
GABA is generally known as the principal inhibitory neurotransmitter in the nervous system, usually acting by hyperpolarizing membrane potential.

Vehicle Optimal Velocity Curves for Minimum-Time Maneuver

open access: yesAdvances in Mechanical Engineering, 2014
A problem in vehicle minimum-time maneuver is the assumption that a vehicle passes through a given path in a minimal amount of time without deviating from the boundary of the given path.

A New Odd Beta Prime-Burr X Distribution with Applications to Petroleum Rock Sample Data and COVID-19 Mortality Rate

open access: yesData, 2023
In this article, we pioneer a new Burr X distribution using the odd beta prime generalized (OBP-G) family of distributions called the OBP-Burr X (OBPBX) distribution.

Research on flow characteristics in supercritical water natural circulation: Influence of heating power distribution

open access: yesNuclear Engineering and Technology, 2018
There are many parameters that affect the natural circulation flow, such as height difference, heating power size, pipe diameter, system pressure and inlet temperature and so on.
