Microbes and the Dissipation of Energy and Respiration: From Cells to Ecosystems
Energy and Respiration From Cells
2015/7/22
In the year 1974, Larry Pomeroy first proposed that microbes were true movers of energy and nutrients in marine food webs (Pomeroy, 1974). This idea was later formalized as the "microbial loop" (Azam ...
This paper considers linear dynamic systems with an interconnection structure specified by a directed graph. We formulate linear matrix inequalities for computation of performance of the system based ...
ABSENCE OF ANOMALOUS DISSIPATION OF ENERGY IN FORCED TWO DIMENSIONAL FLUID EQUATIONS
ABSENCE OF ANOMALOUS DISSIPATION OF ENERGY FORCED TWO DIMENSIONAL FLUID EQUATIONS
2014/4/3
Anomalous dissipation of energy in three dimensional turbulence is one of the basic statements of physical theory [55]. It has been veri ed experimentally to a large degree [75], but not mathematicall...
Coupled Effects of Energy Dissipation and TravellingVelocity in the Run-Out Simulation of High-SpeedGranular
Sliding Granular Mass Granular Temperature Shear Layer Excess Interstitial Pressure
2013/3/7
The run-out of high speed granular masses or avalanches along mountain streams, till their arrest, is analytically modeled. The power balance of a sliding granular mass along two planar sliding surfac...
Spectral-Temporal Simulations of Internal Dissipation Models of Gamma-Ray Bursts
Spectral-Temporal Simulations Internal Dissipation Models Gamma-Ray Bursts
2011/10/19
We present calculations of the time evolution of the prompt spectra of gamma-ray burst models involving generic internal dissipation regions, including internal shocks, either by itself or in the pres...

Equations of mixed hyperbolic and parabolic type oscillations BKW Calculus stability
2011/8/25
Abstract: In the context of some bidimensionnal Navier-Stokes model, we exhibit a family of exact oscillating solutions $\{u_{\epsilon}\}_{\epsilon}$ defined on some strip $[0,T]\times\R^2$ which does...
Dissipation evidence for the quantum damped harmonic oscillator via pseudo-bosons
the quantum damped harmonic oscillator pseudo-bosons
2011/7/26
Abstract: It is known that a self-adjoint, time-independent hamiltonian can be defined for the quantum damped harmonic oscillator. We show here that the two vacua naturally associated to this operator...
Giant strain-sensitivity of acoustic energy dissipation in solids containing dry and saturated cracks with wavy interfaces
strain-sensitivity solids containing dry and saturated cracks
2011/9/2
Mechanisms of acoustic energy dissipation in heterogeneous solids attract much attention in view of their importance for material characterization, nondestructive testing, and geophysics. Due to the ...

Heat Dissipation Nonequilibrium Thermodynamics Quasi-Steady States Open Driven Steady State
2011/9/13
We develop a comparative thermodynamic theory, based on master-equation description of driven chemical reactions, for quasi-steady-state (QSS) and open-system nonequilibrium steady-state (NESS) sustai...

In this paper, we develop a stable and fast numerical scheme for relativistic dissipative hydrodynamics based on Israel-Stewart theory. Israel-Stewart theory is a stable and causal description of diss...
Homochirality through Photon-Induced Melting of RNA/DNA: the Thermodynamic Dissipation Theory of the Origin of Life
Homochirality Photon-Induced Melting RNA/DNA
2011/1/13
The homochirality of the molecules of life has been a vexing problem with no generally accepted solution to date. Since a racemic mixture of chiral nucleotides frustrates the extension and replication...
Dissipation in dynamos at low and high magnetic Prandtl numbers
low and high magnetic Prandtl numbers Solar and Stellar Astrophysics
2011/1/10
Using simulations of helically driven turbulence, it is shown that the ratio of kinetic to magnetic energy dissipation scales with the magnetic Prandtl number in power law fashion with an exponent of ...
Inertial forces and dissipation on accelerated boundaries
High Energy Physics-Theory(hep-th) Quantum Physics(quant-ph)
2010/11/9
We study dissipative effects due to inertial forces acting on matter fields confined to accelerated boundaries in $1+1$, $2+1$, and $3+1$ dimensions. These matter fields describe the internal degrees ...
On the Implications of Late Internal Dissipation for Shallow-Decay Afterglow Emission and Associated High-Energy Gamma-Ray Signals
gamma-rays burst general— gamma rays theory— radiation mechanisms non-thermal
2010/11/10
The origin of the shallow-decay emission during early X-ray afterglows has been an open issue since the launch of the Swift satellite. One of the appealing models is the late internal dissipation mode...
