In this paper we investigate the error threshold for quasispecies with heterogeneous replication accuracy. We show that the coexistence of error-free and error-prone polymerases can greatly increase the error threshold without a catastrophic loss of genetic information. We also show that the error threshold is ...

This paper describes studies of the threshold modulation curve for photographic film. The threshold modulation curve is an empirically derived relation showing the need at any spatial frequency for modulation in the aerial image of a tribar for resolution to be achieved. The paper deals with the history, raison d'�tre, theory, method of measurement, and ...

Threshold anomalies in exchange pion--nucleon forward scattering are treated by the method of dispersion relations. The values of the energy widths of threshold anomalies were obtained. It is shown that the experimental investigation of forward exchange scattering with good accuracy can serve as a sensitive method of studying ...

Approximate corrections to the vertical threshold rigidities for cosmic rays in the earth's magnetic field are given, which take into account both the effects of the nondipole part of the internal field and the penumbra. The thresholds obtained are tabulated every 21/2 deg geographic latitude and every 5 deg geographic longitude. The ...

Internal conversion coefficients were determined experimentally with great accuracy for areas of transition energies which constitute tests for the theories (energies at most ten keV above the K shell threshold); then the results obtained were compared wi...

In the thesis the photoacoustic effect is used to determine the presence of trace gases in air. The method is improved to an extreme sensitivity threshold, so that the behavior of flowers and plants can be studied with unprecedented accuracy.

An augmented Omega System Availability model is presented in which system availability is treated as the probability that navigation accuracy is better than a selected threshold. In addition to the four sub-models used in connection with the previously de...

A method for improving the accuracy of neutron detectors is disclosed wherein a predetermined threshold level, by analysis of a neutron and gamma relative distribution curve, is set and all amplitudes below this predetermined minimum are removed from a neutron detector total count.

The objective of this study was to select the optimal combination of threshold values for the 3x3 pixel spatial filtering for post-classification implanted in Image-100 system of INPE and to evaluate the effects of this procedure on the accuracy of wheat ...

Background and Aims Growth imbalances between individual fruits are common in indeterminate plants such as cucumber (Cucumis sativus). In this species, these imbalances can be related to differences in two growth characteristics, fruit growth duration until reaching a given size and fruit abortion. Both are related to distribution, and environmental factors as well as canopy ...

The present study was designed to estimate the prognosis for patients admitted with threatened abortion on the basis of assays of serum estradiol (E2) and progesterone (P) and the demonstration of fetal heart movements (FHM) by ultrasound scanning. Of the 97 patients included in the study, 35% (with 95% confidence limits 25 to 45%) aborted spontaneously. ...

Due to rapid progress with the LHC commissioning in 2010, set-up beam intensities were soon surpassed and damage potential was reached. One of the key systems for machine protection is the beam loss monitoring (BLM) system. Around 4000 monitors are installed at likely or critical loss locations. Each monitor has 384 associated beam abort thresholds (12 ...

We consider the problem of fault tolerance in the graph-state model of quantum computation. Using the notion of composable simulations, we provide a simple proof for the existence of an accuracy threshold for graph-state computation by invoking the threshold theorem derived for quantum circuit computation. Lower bounds for the ...

The new betatron control system was calibrated using thresholds for photoneutrons from D, Bi, Cu, and for the isochromat from the 15.12 Mev level in carbon. A total of 73 photoneutron thresholds was measured througout the periodic table with an average accuracy of the order of 50 kev. The activation curves for C, N, 0, and F ...

, given the same threshold x, both methods have the same location uncertainty. Thus one can compare how many updates are required by each policy to maintain a given uncertainty threshold x. This is a measure an uncertainty threshold of 0.05 miles the distance policy uses 43% more updates than the deviation policy

The accuracy of prediction methods based on power spectrum analysis depends on the threshold that is used to discriminate between protein coding and non-coding sequences in the genomes of eukaryotes. Because the structure of genes vary among different eukaryotes, it is difficult to determine the best prediction threshold for a ...

Systematic reviews of diagnostic test accuracy studies are increasingly being published, but they can be methodologically challenging. In this paper we present some of the recent developments in the methodology for conducting systematic reviews of diagnostic test accuracy studies. Restrictive electronic search filters are discouraged, as is the use of ...
