A forthcoming article in The Quarterly Review of Biology provides the basis for an argument against using the Gibbs free energy equation to accurately determine the thermodynamics of microbial growth. Microbial growth is a biological process that has been previously treated as a chemical reaction operating in accord with the Gibbs free energy equation, developed during the 1870s. The heat of yeast growth was the first to be measured by direct calorimetry, in 1856. However, the full...

Top Physicists Come To Jerusalem To Mark 40 Years Since Jacob Bekenstein’s Famous Essay On The Entropy Of Black Holes
2012-09-04 09:53:43

Speakers include Nobel laureate and winner of new $3 million physics prize As the scientific community marks 40 years since the publication of Prof. Jacob Bekenstein's famous paper on black hole entropy, the Hebrew University of Jerusalem´s Institute for Advanced Studies is celebrating the occasion by hosting an international conference featuring the world´s top theoretical physicists. The Sep. 3-7 conference, Forty Years of Black Hole Thermodynamics, is presented in cooperation...

New research by a University of Illinois expert who studies process management points to the potential role of regulatory oversight in preventing deterioration of operational routines that are used to complete day-to-day tasks in business organizations. Even in the face of managerial efforts to promote the sustainability of a system, the tendency of operational routines to move toward a state of higher “entropy” is an organizational reality, says Gopesh Anand, a professor of...

Researchers try to get the temperature-independent energy spectrum of some materials for obtaining all their thermodynamic properties from their experimental heat capacities alone. However, measurements are made at finite temperatures in practice, such as with phonon spectra obtained by inelastic neutron scattering, so it is very difficult to obtain a T-independent energy spectrum for any real material. One promising method to obtain such a spectrum is to solve the so-called specific...

The binding of proteins to various substrates in a biological system is a basic but essential process to maintain the function of living things. The mechanisms underlying protein binding have been the focus of theoretical and experimental research for many years. Many mechanisms have been proposed and characterized, including "lock and key", "induced fit", "population shift" and "fly-casting". The recently discovered "fly-casting" mechanism allows a protein chain to unfold and extend to reach...

Scientists at The University of Nottingham have discovered a way to control how tiny flat molecules fit together in a seemingly random pattern. The researchers have been studying molecules which resemble tiny rhombus/diamond shaped tiles, with a side length of around 2 nanometers – 2 billionths of a meter. The fundamental research, published in the prestigious journal Nature Chemistry, has shown that they can prompt the ℠tiles´ to form a range of random patterns by...

University of Oregon theorists overcome loss of entropy and friction in computational simulations University of Oregon researchers have devised a mathematically rich analytic approach to account for often-missing thermodynamic and molecular parameters in molecular dynamic simulations. The new approach, which returns atomistic-level data into the time frame of the macroscopic world, is detailed in a paper appearing online ahead of regular publication in the journal Physical Review E. The...

As politicians know, repetition is often key to getting your message across. Now a former physicist studying linguistics at the Polish Academy of Sciences has taken this intuitive concept and incorporated it into a mathematical model of human communication. In a paper in the AIP's journal Chaos, Łukasz Dębowski mathematically explores the idea that as humans we often repeat ourselves in an effort to get the story to stick. Using statistical observations about the...

Open Systems & Information Dynamics (OSID) is journal published by World Scientific. The aim of the Journal is to promote interdisciplinary research in mathematics, physics, engineering and life sciences centered around the issues of broadly understood information processing, storage and transmission, in both quantum and classical settings. Our special interest lies in the information-theoretic approach to phenomena dealing with dynamics and thermodynamics, control, communication,...
