Abstract:

The equilibration of two coupled reservoirs is studied using a Green function approach that is suitable for future development with the closed time path method. The problem is solved in two parameterizations, to demonstrate the nontrivial issues of parameterization in both the intermediate steps and the interpretation of physical quantities. We use a covariant approach to find self-consistent solutions for the statistical distributions as functions of time. We show that by formally introducing covariant connections, one can rescale a slowly varying nonequilibrium theory so that it appears to b

Abstract:

Our contemporary civilization increasingly relies on creative approaches and solutions. This growing dependence makes issues of control, regulation, and management of the process of creation ever more important. This article finds two major current theoretical perspectives on creativity and the process of creation to be vulnerable in one important respect: their explanation of the production of disequilibrium, which plays a singularly important role in the process of creation, does not pass the test of rational justification. This article suggests that the production of disequilibrium is intim

Abstract:

Abstract The insensitivity of the Antarctic Circumpolar Current (ACC)’s prominent isopycnal slope to changes in wind stress is thought to stem from the action of mesoscale eddies that counterbalance the wind-driven Ekman overturning—a framework verified in zonally symmetric circumpolar flows. Substantial zonal variations in eddy characteristics suggest that local dynamics may modify this balance along the path of the ACC. Analysis of an eddy-resolving ocean GCM shows that the ACC can be broken into broad regions of weak eddy activity, where surface winds steepen isopycnals, and a small number

In metamorphic rocks, mineral species react over a range of pressure–temperature conditions that do not necessarily overlap. Mineral equilibration can occur at varied points along the metamorphic pressure–temperature (PT) path, and thus at different times.

It is also found in the reproductive structures of some algae, moss spores and probably the aerial spores of other terrestrial cryptogamic taxa.

The special cases of localization of strain into a spherical region in three dimensions and into a circular region in two dimensions are further solved for finite solids — spheres in 3D and circles in 2D.

Yttria-stabilized zirconia (YSZ) films are often used as electrolytes, in which only oxygen ions are carriers. In such cases, the open-circuit voltage (OCV = 1.15 V at 1073 K) is equal to the Nernst voltage (Vth = 1.15 V at 1073 K). Samaria-doped ceria (SDC) has higher ionic conductivity than YSZ. Therefore, SDC films are possible electrolyte candidates. However, when SDC electrolytes are used in SOFCs, the OCV at 1073 K is only 0.80 V. The voltage loss has been explained

Abstract:

Ribosomes are essential cellular organelles made up of rRNA and rproteins found in both prokaryotic and eukaryotic cells, and play an important role in protein synthesis. The functional ribosomes are synthesized through the process called ribosome biogenesis, which proceeds with the help of certain factors such as chaperones, ribosomal proteins, and GTPases. GTPases bind to the premature ribosomal subunit and function as a checkpoint, ensuring the proper assembly of other proteins. To aid this process, GTPase undergoes conformational changes, alternating between an active GTP-bound state and a

Abstract This paper provides a critique of the ‘unemployment invariance hypothesis’, according to which the behavior of the labor market, by itself, ensures that the long-run unemployment rate is independent of the size of the capital stock, productivity and the labor force. In the context of an endogenous growth model, we show that the labor market alone need not contain all the equilibrating mechanisms to ensure unemployment invariance; in particular, other markets may perform part of the equilibrating process as well. By implication, policies that raise the growth path of capital or increas

A solid oxide fuel cell (SOFC) converts chemical energy from a fuel gas, such as hydrogen or methane, to electrical energy. In yttria-stabilized zirconia (YSZ) films, only oxygen ions are carriers; thus, these films are often used as electrolytes. In these cases, the open-circuit voltage (OCV = 1.15 V at 1073 K) is equal to the Nernst voltage (Vth = 1.15 V at 1073 K). Samaria-doped ceria (SDC) has a higher ionic conductivity than YSZ. Therefore, SDC films are potential electrolyte candidates. However, when SDC electrolytes are used in SOFCs, the OCV at 1073 K is only 0.80 V. This voltage loss

Abstract:

We analyze two-dimensional (2D) random systems driven by a symmetric Lévy stable noise which in the presence of confining potentials may asymptotically set down at Boltzmann-type thermal equilibria. In view of the Eliazar-Klafter no-go statement, such dynamical behavior is plainly incompatible with the standard Langevin modeling of Lévy flights. No explicit path-wise description has been so far devised for the thermally equilibrating random motion we address, and its formulation is the principal goal of the present work. To this end we prescribe a priori the target pdf ρ∗ in the Boltzmann form

Abstract:

At resonance, a small excitation force amplitude results in a relatively large amplitude system response. Although typically viewed as undesirable, operating a machine near resonance can sometimes be advantageous. A new approach to dynamic spring balancing, called harmonic synthesis, tunes a system so that the desired dynamic motion is approximated by the linear superposition of resonant mode shapes. Large amplitude machine motions are achieved with minimum energy required from system actuators. Machine motion is first approximated using a Fourier series expansion about a mean operating config

This leads to two key challenges on the path to first-principles electrochemistry: (1) including liquid and electrolyte distribution effects on reaction energe

Transmembrane transport of monocarboxylates is conferred by structurally diverse membrane proteins. Here, we describe the pH dependence of lactic acid/lactate facilitation of an aquaporin (AQP9), a monocarboxylate transporter (MCT1, SLC16A1), and a formate–nitrite transporter (plasmodium falciparum FNT, PfFNT) in the equilibrium transport state. FNTs exhibit a channel-like structure mimicking the aquaporin-fold, yet act as secondary active transporters. We used radiolabeled lactate to monitor uptake via yeast-expressed AQP9, MCT1, and PfFNT for long enough time periods to reach the equilibrium

Background L-type calcium channels (LCCs) are macro-molecular complexes that conduct ICaL and are involved in several critical functions in cardiac, skeletal, neuronal, smooth muscle, and endocrine cells. In common with other ionic channels they can be studied by isolating and overexpressing in a cell line, and the current through them can be measured using patch-clamp experiments. However, LCC current recordings are known to be contaminated with attenuation of current, known as ‘rundown’. Previous work has shown that increased accumulation of intracellular calcium is likely associated with in

By applying lead potential analysis to the models, the C mechanism, which is dependent on potentiation of Na+/Ca2+ exchange current via spontaneous Ca2+ release from the sarcoplasmic reticulum (SR) during diastole, was found to overlap M mechanisms in

Ordinary ice has a proton-disordered phase which is kinetically metastable, unable to reach, spontaneously, the ferroelectric (FE) ground state at low temperature where a residual Pauling entropy persists. Upon light doping with KOH at low temperature, the transition to FE ice takes place, but its microscopic mechanism still needs clarification. We introduce a lattice model based on dipolar interactions plus a competing, frustrating term that enforces the ice rule (IR). In the absence of IR-breaking defects, standard Monte Carlo (MC) simulation leaves this ice model stuck in a state of disorde
