On the Effectiveness of Projection Methods for Convex Feasibility Problems with Linear Inequality Constraints
Y. Censor, W. Chen, P. L. Combettes +2
The effectiveness of projection methods for solving systems of linear inequalities is investigated. It is shown that they have a computational advantage over some alternatives and…
Vector bundles trivialized by proper morphisms and the fundamental group scheme
Indranil Biswas, Joao Pedro P. dos Santos
Let X be a smooth projective variety defined over an algebraically closed field k. Nori constructed a category of vector bundles on X, called essentially finite vector bundles, whi…
Search for Fermion-Pair Decays $Q\Qbar \to (\t\Wmp)(\tbar\Wpm)$ in Same-Charge Dilepton Events
The CDF Collaboration
We report the most restrictive direct limits on masses of fourth-generation down-type quarks , and quark-like composite fermions ( or ), decaying promptly t…
Proximal Splitting Methods in Signal Processing
Patrick L. Combettes, Jean-Christophe Pesquet
The proximity operator of a convex function is a natural extension of the notion of a projection operator onto a convex set. This tool, which plays a central role in the analysis a…
A Measurement of Coherent Neutral Pion Production in Neutrino Neutral Current Interactions in NOMAD
C. T. Kullenberg, S. R. Mishra
We present a study of exclusive neutral pion production in neutrino-nucleus Neutral Current interactions using data from the NOMAD experiment at the CERN SPS. The data correspond t…
Search for New Color-Octet Vector Particle Decaying to ttbar in ppbar Collisions at TeV
The CDF Collaboration, T. Aaltonen
We present the result of a search for a massive color-octet vector particle, (e.g. a massive gluon) decaying to a pair of top quarks in proton-antiproton collisions with a center-o…
