The highest energy cosmic rays observed possess macroscopic energies and their origin is likely to be associated with the most energetic processes in the Universe. Their existence triggered a flurry of theoretical explanations ranging from conventional shock acceleration to particle physics beyond the Standard Model and processes taking place at the earliest moments of our Universe. Furthermore...

We have combined and integrated our previously developed librarybased Growth and Monte Carlo simulation techniques in order to allow for both thorough sampling and free energy measurements of all-atom peptides. The integrated growth and relaxation technique makes use of pre-calculated Boltzmann distributed statistical libraries of molecularfragments and their corresponding energies. Due to this...

This paper proposes a new B-spline based active contour model for extracting areas of interest in an image. The model is governed by original external and internal energies. A self-adaptive technique for energies regulation is used to improve the convergence in terms of quality and rapidity. An adding control point procedure is introduced in order to improve the active contour convergence towar...

The study of multiple gauge boson production at the TeV scale constitutes a unique opportunity to test the Standard Model (SM) of electroweak interactions at the highest possible energies. The production of WZ events via s-channel allows to probe triple gauge-boson couplings in modelindependent manner at the energies never attained before and improve our understanding of the gauge theory. Any d...

We study the properties of fluctuation for the free energies and internal energies of two spin glass systems that differ for having some set of interactions flipped. We show that their difference has a variance that grows like the volume of the flipped region. Using a new interpolation method, which extends to the entire circle the standard interpolation technique, we show by integration by par...

We evidence the existence of a universal correlation between the binding energies of successive four-boson bound states (tetramers), for large two-body scattering lengths (a), related to an additional scale not constrained by three-body Efimov physics. Relevant to ultracold atom experiments, the atom-trimer relaxation peaks for |a|→∞ when the ratio between the tetramer and trimer energies is ≃4...

We report on recent results obtained by the above collaboration on the collision processes involving three nucleons, where we pay particular attention on the dynamical role of the pion. After discussing the case at intermediate energies, where real pions can be produced and detected, we have considered the case at lower energies, where the pions being exchanged are virtual. The study has reveal...

We describe and apply a new procedure that allows a direct determination of dissociation energies of polyatomic systems (clusters, fullerenes, polymers, and other molecules) without any modeling of the systems under investigation. As an example, we have determined the dissociation energies of a series of gold clusters Au(+)n. A comparison with values obtained from statistical models of unimolec...

Protein design software places amino acid side chains by precomputing rotamer-pair energies and optimizing rotamer placement. If the software optimizes by rapid stochastic techniques, then the precomputation phase dominates run time. We present a new algorithm for rapid rotamer-pair energy computation that uses a trie data structure. The trie structure avoids redundant energy computations, and ...
