Heptagons from the Steinmann Cluster Bootstrap [PDF]

open access: yes, 2017
We reformulate the heptagon cluster bootstrap to take advantage of the Steinmann relations, which require certain double discontinuities of any amplitude to vanish.

Normal spaces whose Stone-Čech remainders have countable tightness [PDF]

open access: yesProceedings of the American Mathematical Society, 1993
Summary: We prove, assuming the Proper Forcing Axiom (PFA), that each normal space whose Stone-Čech remainder has countable tightness is ACRIN. A normal space \(X\) is called ACRIN if each of its regular images is normal. \textit{W. Fleissner} and \textit{R. Levy} [ibid.

A Central Limit Theorem for the Empirical Process of a Long Memory Linear Sequence [PDF]

open access: yes, 1994
A central limit theorem for the normalized empirical process, basedon a (non-Gaussian) moving average sequence X_t , t in Z, with long memory,is established, generalizing the results of Dehling and Taqqu (1989).

Chirikov and Nekhoroshev diffusion estimates: bridging the two sides of the river [PDF]

open access: yes, 2013
We present theoretical and numerical results pointing towards a strong connection between the estimates for the diffusion rate along simple resonances in multidimensional nonlinear Hamiltonian systems that can be obtained using the heuristic theory of ...

Normalizations with Exponentially Small Remainders for Nonautonomous Analytic Periodic Vector Fields [PDF]

open access: yesJournal of Dynamics and Differential Equations, 2012
In this paper we deal with analytic nonautonomous vector fields with a periodic time-dependancy, that we study near an equilibrium point. In a first part, we assume that the linearized system is split in two invariant subspaces E0 and E1. Under light diophantine conditions on the eigenvalues of the linear part, we prove that there is a polynomial ...

Antiviral therapy in acute viral hepatitis B: why and when

open access: yesInfectious Agents and Cancer, 2009
Acute viral hepatitis B is cleared in more than 95% of patients, while the remainder ones may develop either chronic HBV infection or, rarely, fulminant hepatitis. Therefore there are elderly patients with severe acute HBV hepatitis caractherized by high

Rational Dyck Paths in the Non Relatively Prime Case [PDF]

open access: yes, 2016
We study the relationship between rational slope Dyck paths and invariant subsets of $\mathbb Z,$ extending the work of the first two authors in the relatively prime case.

Robust Image Embedded Watermarking Using DCT and Listless SPIHT

open access: yesFuture Internet, 2017
This paper presents a DCT-based (DCT: discrete cosine transform) listless set partitioning in hierarchical trees (SPIHT) digital watermarking technique that is robust against several common attacks such as cropping, filtering, sharpening, noise ...
