Solution estimates and stability tests for linear neutral differential equations [PDF]

Appl. Math. Lett., V. 108 (2020), October 2020, # 106515, 8 pp, 2020
Explicit exponential stability tests are obtained for the scalar neutral differential equation $$ \dot{x}(t)-a(t)\dot{x}(g(t))=-\sum_{k=1}^m b_k(t)x(h_k(t)), $$ together with exponential estimates for its solutions. Estimates for solutions of a non-homogeneous neutral equation are also obtained, they are valid on every finite segment, thus describing ...

Testing Long Run Neutrality [PDF]

, 1992
Key classical macroeconomic hypotheses specify that permanent changes in nominal variables have no effect on real economic variables in the long run. The simplest “long-run neutrality” proposition specifies that a permanent change in the money stock has no long-run consequences for the level of real output.

TESTING κ-POINCARÉ WITH NEUTRAL KAONS [PDF]

Modern Physics Letters A, 2000
In recent work on experimental tests of quantum-gravity-motivated phenomenological models, a significant role has been played by the so-called "κ" deformations of Poincaré symmetries. Sensitivity to values of the relevant deformation length λ as small as 5×10-33 m has been achieved in recent analyses comparing the structure of κ-Poincaré symmetries ...

Tests of the Equivalence Principle with neutral kaons [PDF]

Physics Letters B, 1999
We test the Principle of Equivalence for particles and antiparticles, using CPLEAR data on tagged K0 and K0bar decays into pi^+ pi^-. For the first time, we search for possible annual, monthly and diurnal modulations of the observables |eta_{+-}| and phi_{+-}, that could be correlated with variations in astrophysical potentials.

THE HOMOZYGOSITY TEST OF NEUTRALITY [PDF]

Genetics, 1978
ABSTRACT An earlier paper showed that the homozygosity (of a population or sample) was a good statistic for testing departures from selective neutrality in the direction of heterozygote advantage or disadvantage. It is here shown that homozygosity is also influenced by the presence of deleterious alleles and by other departures from ...

Neutrality Tests for Sequences with Missing Data [PDF]

Genetics, 2012
Abstract Missing data are common in DNA sequences obtained through high-throughput sequencing. Furthermore, samples of low quality or problems in the experimental protocol often cause a loss of data even with traditional sequencing technologies. Here we propose modified estimators of variability and neutrality tests that can be naturally

Statistical tests of neutrality of mutations. [PDF]

Genetics, 1993
Abstract Mutations in the genealogy of the sequences in a random sample from a population can be classified as external and internal. External mutations are mutations that occurred in the external branches and internal mutations are mutations that occurred in the internal branches of the genealogy.

Kinetic Simulation of Ion Thruster Plume Neutralization in a Vacuum Chamber [PDF]

, 2023
The electrical environment of a ground vacuum testing chamber creates facility effects for gridded ion thrusters. For example, it is well known that the plume from the thruster generates current paths that are very different from what occurs in space, and the neutralization of this plume is also different.

Testing the neutral hypothesis of phenotypic evolution [PDF]

Proceedings of the National Academy of Sciences, 2016
SignificanceDespite the universal recognition that adaptation by Darwinian selection can shape phenotypic variations within and between species, it remains unknown whether most phenotypic variations observed have adaptive values, in part because addressing this question requires examining a large, random set of traits while past studies were biased ...

TESTING NEUTRALITY IN SUBDIVIDED POPULATIONS [PDF]

Genetics, 1982
ABSTRACT Statistical tests of the neutrality hypothesis that are based on the sampling theory of Ewens (1972) require the assumption of panmixia. It is proposed that for a population comprising numerous local populations with weak gene flow among them, tests based on Ewens' theory can be applied separately to samples from each local ...
