The sharp for the Chang model is small

William J. Mitchell
2017 Archive for Mathematical Logic  
Woodin has shown that if there is a measurable Woodin cardinal then there is, in an appropriate sense, a sharp for the Chang model.  ...  We produce, in a weaker sense, a sharp for the Chang model using only the existence of a cardinal κ having an extender of length κ^+ω_1.  ...  Then KpRq C , the core model over the reals as defined in the Chang model, is an iterated ultrapower (without drops) of KpRq V ; in particular, there is no sharp for the Chang model.  ...

On hysteresis in magnetic lenses of electron microscopes

P.J. van Bree, C.M.M. van Lierop, P.P.J. van den Bosch
2010 2010 IEEE International Symposium on Industrial Electronics  
Because this model introduces the intermediate magnetic field variable, it is possible to reconstruct and explain the results observed in the experiments.  ...  Hysteresis expresses itself in the relation between the input current applied to the lens-coil and the level of sharpness (defocus) of the resulting images.  ...  The quasi-static experiments already showed a drastic decrease in sharpness for changes of ΔI ≤ 0.3%, now the input is varied up to 10%.  ...

Evaluation of Smagorinsky variants in large-eddy simulations of wall-resolved plane channel flows

Johan Meyers, Pierre Sagaut
2007 Physics of Fluids  
Further, the effect of changes in the shape of the high-pass filter used for the three models is investigated. A sharp cutoff filter and a Gaussian high-pass filter are considered.  ...  The subsequent small-scale extraction of this term is used as a model.  ...  An evaluation of the models' sensitivity to changes in ␤ is presented in Fig. 11 for sharp cutoff high-pass filters and the three models A-C, and in Fig. 12 for Gaussian high-pass filters.  ...

The influence of a sharp change of temperature gra- dient on the integral properties of a star (compared with the case in which all changes occur gradually) is found to be extremely small.  ...  Choice of stellar model For simplicity we shall assume that the outer convection zone contains only a small fraction of the stellar mass, but is not necessarily shallow in terms of radius.  ... 

A Chip that Focuses an Image on Itself [chapter]

T. Delbrück
1989 The Kluwer International Series in Engineering and Computer Science  
For our model, the primary hypothesis about this system is that control signals are generated actively, by the motor system in the course of control.  ...  In the modeling of neural systems, time is often treated as a sequencer, rather than as an expresser of information.  ...  I thank Hewlett-Packard for computing support, and DARPA and MOSIS for chip fabrication.

An empirical study of nonlinear adjustment in the UIP model using a smooth transition regression model

Dandan Li, Atanu Ghoshray, Bruce Morley
2013 International Review of Financial Analysis  
This study considers the nonlinear relationship between the expected exchange rate change and the interest rate differential, using STR models (ESTR and LSTR), with Sharpe ratios, interest rate differentials  ...  The results generally conclude that UIP holds with the larger Sharpe ratio and higher exchange rate volatility regime, which is consistent with the transaction costs and limits to speculation hypotheses  ...  The Sharpe ratio is too small to attract speculative capital, so traders would not exploit any bias.  ...

Pairs Trading with Nonlinear and Non-Gaussian State Space Models [article]

Guang Zhang
2020 arXiv   pre-print
This new model has two distinctive features: (1) The innovations to the spread is non-Gaussianity and heteroskedastic. (2) The mean reversion of the spread is nonlinear.  ...  The results show that the new approach can achieve a 21.86% annualized return for the PEP/KO pair and a 31.84% annualized return for the EWT/EWH pair.  ...  A well-known feature of financial time-series is volatility clustering: "large changes tend to be followed by large changes, of either sign, and small changes tend to be followed by small changes" (Mandelbrot  ...

Mechanisms underlying attraction to odors in walking Drosophila

Liangyu Tao, Siddhi Ozarkar, Vikas Bhandawat
2020 PLoS Computational Biology  
Similarly, the inward bias of the turns is a result of the increase in turn angle. These two mechanisms entirely account for the change in a fly's locomotion.  ...  In the absence of ORN activation, the fly's locomotion can be described by a random walk model where a fly's movement is described by its speed and turn-rate (or kinematics).  ...  Acknowledgments We would like to acknowledge the members of Bhandawat lab for discussions, and Nicholas Lent for help with experiments.  ...
