Interplay of Spin and Orbital Angular Momentum in the Proton [PDF]
Phys.Rev.Lett.101:102003,2008, 2008 We derive the consequences of the Myhrer-Thomas explanation of the proton spin problem for the distribution of orbital angular momentum on the valence and sea quarks. After QCD evolution these results are found to be in very good agreement with both recent lattice QCD calculations and the experimental constraints from Hermes and JLab.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Objective To develop and validate a HyperArc‐based RapidPlan (HARP) model for three‐fraction brain stereotactic radiotherapy (SRT) plans to then use to replan previously treated five‐fraction SRT plans. Demonstrating the possibility of reducing the number of fractions while achieving acceptable organs‐at‐risk (OAR) doses with improved target ...

Resolution of the finite Markov moment problem [PDF]
Comptes Rendus de l Acad\'emie des Sciences - Series I -
Mathematics 341, 12 (2005) 775-780, 2009 We expose in full detail a constructive procedure to invert the so--called "finite Markov moment problem". The proofs rely on the general theory of Toeplitz matrices together with the classical Newton's relations.

Annals of Clinical and Translational Neurology, EarlyView.Abstract Objective A substantial part of central nervous system (CNS) disorders remains unexplained, despite various new and minimally invasive diagnostic techniques. Within this rapidly developing diagnostic field, the precise role of brain biopsy is unknown.

European Union Enlargement: Prospects and Potential Pitfalls Along the Way [PDF]
, 1999 [From the Introduction]. Enlarging the European Union (EU) is a multi-faceted process, marked by the milestones of the application for membership by a state, issuance of the opinion of the European Commission on that application, a decision by the ...

Advanced Biology, EarlyView.Positively supercharged mGreenLatern protein is self‐assembled electrostatically with negatively charged zinc phthalocyanines to yield bio‐based photoactive materials in aqueous media. The addition of phthalocyanines results in the formation of large complexes fully quenching of the protein fluorescence. The results indicate an energy transfer from the

The Segal--Bargmann transform for odd-dimensional hyperbolic spaces [PDF]
Mathematics 2015, 3(3), 758-780, 2015 We develop isometry and inversion formulas for the Segal--Bargmann transform on odd-dimensional hyperbolic spaces that are as parallel as possible to the dual case of odd-dimensional spheres.
