2019 arXiv   pre-print
(ii) Rounding errors in deterministic floating-point computations (Vignes [56] ).  ...  According to the thermal interpretation, the object described by this 2-photon system is an extended object. Over long distances, the uncertainty intrinsic to the 2-photon system becomes huge.  ...

Bi-galileon theory II: phenomenology

Antonio Padilla, Paul M. Saffin, Shuang-Yong Zhou
2011 Journal of High Energy Physics  
Whereas the galileon description is valid all the way down to solar system scales for the self-accelerating models, unfortunately the same cannot be said for self tuning models owing to the scalars backreacting  ...  We continue to introduce bi-galileon theory, the generalisation of the single galileon model introduced by Nicolis et al.  ...  This suggests that bi-galileon inspired cosmological models are worth developing further as a viable alternative to dark energy. II.  ...

Statistical hadronization and hadronic micro-canonical ensemble II

F. Becattini, L. Ferroni
2004 European Physical Journal C: Particles and Fields  
We have also studied the fitness of a previously proposed computing method, based on the Metropolis Monte-Carlo algorithm, for event generation in the statistical hadronization model.  ...  The most suitable method is to decompose into the sum of the phase space volumes with fixed particle multiplicities for each species: = {Nj} {Nj } δ Q, j Nj qj (3) {N j } being a vector of K integer  ...  a set of colourless massive extended objects, defined as clusters (or fireballs).  ...

From Type II string theory toward BSM/dark sector physics

Generalized polarizabilities of the nucleon studied in the linear sigma model (II)

A. Metz, D. Drechsel
1997 Zeitschrift für Physik A Hadrons and Nuclei  
We have now extended this work and calculated the 7 vector polarizabilities showing up in the spin-dependent amplitude of virtual Compton scattering.  ...  The results fulfill 3 model-independent constraints recently derived. Compared to the constituent quark model there exist enormous differences for some of the vector polarizabilities.  ...  In conclusion, the generalized vector polarizabilities represent suitable observables to distinguish between different models, and, in particular, to test the chiral structure of the nucleon.  ...

Isotropic loop quantum cosmology with matter. II. The Lorentzian constraint

Franz Hinterleitner, Seth Major
2003 Physical Review D, Particles and fields  
As in the Euclidean case, the discreteness of quantum geometry removes the classical singularity from the quantum Friedmann models.  ...  In both cases it is possible to extend the principle series beyond the singularity to negative values of the discrete internal time n.  ...  By defining p := a 2 sgn(a) ( 1 ) the domain of a now extends to negative values.  ...

The standard formula of Solvency II: a critical discussion

Matthias Scherer, Gerhard Stahl
2020 European Actuarial Journal  
Compared to Solvency I, the SF of Solvency II is considered a significant improvement, as many of the aforementioned desiderata have been much better realized.  ...  The stochastic model underneath the SF is still subject to considerable uncertainties; so that the probability functional of the SF is exposed to significant model risk.  ...  These subjective components go beyond the inevitable subjective elements of an objective model (1) .  ...

A Modified Dolph-Chebyshev Type II Function Matched Filter for Retinal Vessels Segmentation

Dhimas Dharmawan, Boon Ng, Susanto Rahardja
2018 Symmetry  
The algorithm utilizes a directionally sensitive matched filter bank using a modified Dolph-Chebyshev type II basis function and a new method to combine the matched filter bank's responses.  ...  Then, the FOV is extended using the method in [9] to remove a sharp change between the FOV and the region beyond the FOV.  ...  In addition, it is also shown that MDCF-II with an appropriate scale is the most suitable model for retinal vessels with thin, medium and thick widths.  ...

Hypergeometric continuation of divergent perturbation series: II. Comparison with Shanks transformation and Padé approximation

Sören Sanders, Martin Holthaus
2017 Journal of Physics A: Mathematical and Theoretical  
Using the example of strong-coupling perturbation series provided by the two-dimensional Bose-Hubbard model, we compare hypergeometric continuation to Shanks and Pad\'e techniques, and demonstrate that  ...  E n (λ = 1) = (n + 1/2) with = ω 2 0 + ω 2 1 .  ...  Therefore, for both ω 1 ω 0 and ω 1 > ω 0 the summed perturbation series yields E n (λ = 1) = ω 0 (n + 1/2) 1 + ω 1 ω 0 2 , (12) which, of course, equals the above expression (5) .  ...
