Supercoiling Induces Denaturation Bubbles in Circular DNA

Giovanni Dietler

We present a theoretical framework for the thermodynamic properties of supercoiling-induced denaturation bubbles in circular double-stranded DNA molecules. We explore how DNA supercoiling, ambient salt concentration, and sequence heterogeneity impact on th ...

Dynamic density functional theory versus kinetic theory of simple fluids

By combining methods of kinetic and density functional theory, we present a description of molecular fluids which accounts for their microscopic structure and thermodynamic properties as well as their hydrodynamic behavior. We focus on the evolution of the ...

Kinetic modeling of the central carbon metabolism of Escherichia Coli

Vassily Hatzimanikatis, Ljubisa Miskovic

Precise information about kinetic properties of enzymes within a biochemical network is a necessary ingredient of any successful metabolic engineering design. Such information inevitably involves uncertainty due to changes in cellular and process parameter ...

Looping probabilities of elastic chains: A path integral approach

John Maddocks, Ludovica Cotta-Ramusino

We consider an elastic chain at thermodynamic equilibrium with a heat bath, and derive an approximation to the probability density function, or pdf, governing the relative location and orientation of the two ends of the chain. Our motivation is to exploit ...

Efficient stochastic thermostatting of path integral molecular dynamics

Michele Ceriotti, Michele Parrinello

The path integral molecular dynamics (PIMD) method provides a convenient way to compute the quantum mechanical structural and thermodynamic properties of condensed phase systems at the expense of introducing an additional set of high frequency normal modes ...

Evidence for Thermal Spin-Transfer Torque

Jean-Philippe Ansermet, Haiming Yu, Simon Granville

Large heat currents are obtained in Co/Cu/Co spin valves positioned at the middle of Cu nanowires. The second harmonic voltage response to an applied current is used to investigate the effect of the heat current on the switching of the spin valves. Both th ...

Thermal-Aware Workload Scheduling for Energy Efficient Data Centers

Nedeljko Vasic

Increasing heat dissipation density is becoming a limiting factor in air-cooled data centers. The main control objective in data center thermal management is to keep the temperature of all the data processing equipment below a certain threshold and at the ...

Quantitative Analysis of Metabolic Networks Through the Explicit Consideration of Kinetic Mechanisms

Vassily Hatzimanikatis, Ljubisa Miskovic

Engineering of large-scale metabolic pathways to maximize production of a certain substance or to minimize creation of undesired chemicals require explicit information about the underlying enzyme kinetics. Unfortunately, such information is frequently not ...

Network thermodynamics in the post-genomic era

Vassily Hatzimanikatis, Keng Cher Soh

Network models have been used to study the underlying processes and principles of biological systems for decades, providing many insights into the complexity of life. Biological systems require a constant flow of free energy to drive these processes that o ...

Phase transitions in full counting statistics for periodic pumping

Dmitri Ivanov

We discuss the problem of full counting statistics for periodic pumping. The probability generating function is usually defined on a circle of the "physical" values of the counting parameter, with its periodicity corresponding to charge quantization. The e ...
