Beating the Standard Model *
Although our beloved standard model of quarks and leptons offers a complete, consistent and correct description of most particle phenomena, lots of vexing questions remain unanswered, such as: Why are the gauge group and the fermion masses what they are? Why three families of quarks and leptons? What breaks electroweak symmetry? How about gravity? Leaving such profound meta-questions to supersy...
متن کاملBeating the jetting regime
We study numerically the dynamics of jets and drops in a microcapillary coflow device. The co-flow stream encounters different flow regimes, including dripping, jetting. Using a level-set/finite element axysimmetric numerical simulation, we study the dynamics of breakup of a jet subject to flow rate perturbations. A scaling law for the width of the unperturbed jet is presented and compared to e...
متن کاملBeating the Pink
Introduction: Kaposi sarcoma (KS) is an HIV associated skin lesion. Kaposi sarcoma is rare in HIV negative patients and is associated with HHV-8 infection. Clinically it presents as a pink nodular mass, single or multiple which can mimic pyogenic granuloma and bacillary angiomatosis. The etiology associated with HHV-8. Treatment options modalities can vary between from electrocuatery to surgica...
متن کاملBeating Elo
where EA and EB are the expected outcomes for players A and B, and RA and RB are their ratings. Here we designate a win by 1, a loss by 0, and a draw by 0.5. The spread of the ratings is set by Λ, which for chess ratings is usually taken to be Λ = 400/ log(10) = 173.72. The result of each game updates each player’s rating according to an update rule. The update rule is usually based on the diff...
متن کاملParameterized TSP: Beating the Average
In the Travelling Salesman Problem (TSP), we are given a complete graph Kn together with an integer weighting w on the edges of Kn, and we are asked to find a Hamilton cycle of Kn of minimum weight. Let h(w) denote the average weight of a Hamilton cycle of Kn for the weighting w. Vizing (1973) asked whether there is a polynomialtime algorithm which always finds a Hamilton cycle of weight at mos...
