“I’ve never touched the hard stuff, only smoked grass a few times with the boys to be polite, and that’s all, though ten is the age when the big guys come around teaching you all sorts to things. But happiness doesn’t mean much to me, I still think life is better. Happiness is a mean son of a bitch and needs to be put in his place. Him and me aren’t on the same team, and I’m cutting him dead. I...

Maximizing a monotone submodular function subject to a b-matching constraint is increasing in importance due to the application for the content spread maximization problem, but few practical algorithms are known other than the greedy algorithm. The best approximation scheme so far is the local search algorithm, proposed by Feldman, Naor, Schwartz, Ward (2011). It obtains a 1/(2+ 1 k +ε)-approxi...

Turbulence plays an important role in many chemical engineering processes (fluid flow, mass and heat transfer, chemical reactions) which are dominated by convective transport. Since the direct numerical simulation (DNS) of turbulent flows is still prohibitively expensive, eddy viscosity models based on the Reynolds Averaged Navier-Stokes (RANS) equations are commonly employed in CFD codes. One ...

We analyze the data of the elastic electron proton scattering to look for modelindependent evidence of the two-photon-exchange (TPE) effect. We fix the value of R = GE/GM as determined from the data of the polarization transfer experiment and parametrize the TPE contribution in forms which are consistent with the constraint derived from crossing symmetry and the charge conjugation. In contrast ...

The widespread use of biogas and biomass fuels in facility agro-industrial parks has led to a significant increase their carbon emissions. A day-ahead optimal scheduling model for an integrated energy system (IES) is proposed, that considers the coupling power gas (P2G) reduce emissions during operation industrial park. proposed incorporates two evaluation indices economy by IES park, formulate...

CP violation in the neutral kaon system is known to be dominated by the mixing of K 0 and K 0. Direct CP violation in the 2 pion decays of neutral kaons has been a controversial subject over the last decade. A strong experimental effort has been devoted to the precise measurement of the direct CP violation parameter ℜe (ε ′ /ε). After 10 years of detector development, data collection and analys...

We present a detailed analysis of ε/ε within the Standard Model, taking into account the strong enhancement through final–state interactions identified in refs. [1] and [2]. The relevant hadronic matrix elements are fixed at leading order in the 1/NC expansion, through a matching procedure between the effective short–distance Lagrangian and its corresponding low–energy description in Chiral Per...

I discuss the comparison of the current theoretical calculations of ε/ε with the experimental data. Lacking reliable “first principle” calculations, phenomenological approaches may help in understanding correlations among different contributions and available experimental data. In particular, in the chiral quark model approach the same dynamics which underlies the ∆I = 1/2 selection rule in kao...

Motivated by several applications, we consider the problem of randomly rounding a fractional solutionin a matroid (base) polytope to an integral one. We consider the pipage rounding technique [5, 6, 36] andalso present a new technique, randomized swap rounding. Our main technical results are concentrationbounds for functions of random variables arising from these rounding techniques...

In this paper we consider several instances of the k-center on a line problem where the goal is, given a set of points S in the plane and a parameter k ≥ 1, to find k disks with centers on a line l such that their union covers S and the maximum radius of the disks is minimized. This problem is a constraint version of the well-known k-center problem in which the centers are constrained to lie in...
