Theoretical limits of holographic quintessence

by Yin-zhe Ma A, Xin Zhang A , 709
"... The holographic dark energy model is one of the important ways for dealing with the dark energy problems in the quantum gravity framework. In this model, the dimensionless parameter c plays an essential role in determining the evolution of the holographic dark energy. In particular, the holographic ..."
Abstract - Add to MetaCart
dark energy with c ≥ 1 can be effectively described by a quintessence scalar-field. However, the variation of the quintessence scalar-field should be less than the Planck mass, which would give theoretic constraints on the parameters c and Ωm0. Therefore, we get the theoretical limits on the parameter

Impulses and Physiological States in Theoretical Models of Nerve Membrane

by Richard Fitzhugh - Biophysical Journal , 1961
"... ABSTRACT Van der Pol's equation for a relaxation oscillator is generalized by the addition of terms to produce a pair of non-linear differential equations with either a stable singular point or a limit cycle. The resulting "BVP model " has two variables of state, representing excitabi ..."

The Theoretical Limit to Plant Productivity

by unknown authors
"... ABSTRACT: Human population and economic growth are accelerating the demand for plant biomass to provide food, fuel, and fiber. The annual increment of biomass to meet these needs is quantified as net primary production (NPP). Here we show that an underlying assumption in some current models may lead ..."

an upper-envelope NPP unconstrained by resource limitations. This theoretical maximum NPP approached 200 tC ha−1 yr−1 at point locations, roughly 2 orders of magnitude higher than most current managed or natural ecosystems. Recalculating the upper envelope estimate of NPP limited by available water reduced

Theoretical Limit to Monetarism

by Shuji Nishijima
"... The purpose of the study here is to challenge present orthodoxy in economics namely Mone-tarists. By Monetarist, I focus on Milton Friedman, since Friedman is the most influential Mone-tarist in the World. Friedman is not only the most influential monetarist, but also one of the most distinguished e ..."

University’s Lady Mar-garet Hall on the occasion of the Econometric Society World Congress in Cambridge. After the speech there were questions. First the late Professor Joan Robinson asked whether monetarism had any theoretical foundation. Professor Friedman answered that monetarism was an empirical matter

Genes and Spectrum: The Theoretical Limits

by Sebastian G. B. Amyes, From Department, Medical Microbiology, The Medical School
"... Antibiotic resistance can result either from mutations within a chromosomal gene or from mobile genes imported from outside. In the last 15 years, some of these mobile genes have shown a propensity to adapt to successive antibiotic challenges, the most versatile being the class A b-lactamases. The T ..."

Antibiotic resistance can result either from mutations within a chromosomal gene or from mobile genes imported from outside. In the last 15 years, some of these mobile genes have shown a propensity to adapt to successive antibiotic challenges, the most versatile being the class A b-lactamases. The TEM and SHV b-lactamase nuclei, usually after one initial critical mutation, allow a series of successive mutations that increase the spectrum to hydrolyze most cephalosporins. The class C b-lactamases also show some versatility; while it migrates from the chromosome, subtle changes can occur in the gene to broaden the spectrum. Trimethoprim resistance has shown less adaptability in gram-negative bacteria, but in gram-positive organisms the plasmid has captured the chromosomal dihydrofolate reductase of Staphylococcus epidermidis, and a minimal number of changes have occurred that decrease the binding of trimethroprim. Other resistance mechanisms appear less adaptable, relying rather on the importation of new genes to cope with new challenges. The introduction of molecular biological techniques to the replication because there is no replication of the transposon during the transposition process [6, 7]. On the other hand,study of antibiotic resistance genes has enabled us to follow the spread and evolution of these genes through the clinical class II transposons contain a transposase, which sets up a co-integrate intermediate between the transposon-containing repli-population. What is the most significant factor in the diversifi-

Information-theoretic Limitations of Formal Systems

by Gregory J. Chaitin - JOURNAL OF THE ACM , 1974
"... An attempt is made to apply information-theoretic computational complexity to metamathematics. The paper studies the number of bits of instructions that must be a given to a computer for it to perform finite and infinite tasks, and also the amount of time that it takes the computer to perform these ..."

Dynamic Tuning of the IEEE 802.11 Protocol to Achieve a Theoretical Throughput Limit

by Frederico Calì, Marco Conti, Enrico Gregori - IEEE/ACM TRANSACTIONS ON NETWORKING , 2000
"... In wireless LANs (WLANs), the medium access control (MAC) protocol is the main element that determines the efficiency in sharing the limited communication bandwidth of the wireless channel. In this paper we focus on the efficiency of the IEEE 802.11 standard for WLANs. Specifically, we analytically ..."

analytically derive the average size of the contention window that maximizes the throughput, hereafter theoretical throughput limit, and we show that: 1) depending on the network configuration, the standard can operate very far from the theoretical throughput limit; and 2) an appropriate tuning of the backoff
