Search for the R(3520) crypto-exotic state at BABAR
No full textThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Motivated by the recent discoveries of exotic and possible crypto-exotic states, presented in this thesis is an inclusive search for the production of a crypto-exotic baryon state called R(3520) with hidden charm in e+e− interactions at a centre of mass energy of 10.58 GeV in the data collected at the energy Υ(4S) resonance with the BABAR detector using a data set of 228 fb−1. Hints about the existence of the R(3520) state were reported in an analysis of data from a 2m hydrogen bubble chamber experiment at CERN.
Two decay modes of the R(3520) resonance were investigated in this thesis R(3520) → pK+π−π−K0
S and R(3520) → pK+π−K∗−. The invariant mass spectra of the two final states were analysed and no evidence for the state was observed. Therefore, Upper limits were set on the differential cross section for the production of the R(3520) as a function of the momentum in the centre of mass frame. Using these differential cross sections the total cross sections were calculated with two different hypotheses for the width of the resonance, 1MeV/c2 and 7MeV/c2, with the additional assumption that the momentum spectrum for the production of state is flat. The upper limits for the total cross section production of the R(3520) for the decay mode p π− π− K+ K0 S were calculated to be 32 fb/GeV/c (48 fb GeV/c) with the 1MeV/c2 (7 MeV/c2) width. For the decay mode p π− K+ K∗− the upper limits on the total cross section were 62 fb/ GeV/c (93 fb/ GeV/c) for the 1MeV/c2 (7 MeV/c2) width hypotheses. The studies were repeated with the additional requirement that there was an additional antiproton in the event. The invariant mass spectra were analysed and no evidence for the state was found. Therefore, upper limits were calculated on the differential cross sections and the total cross sections for the production of this state. The upper limits for the total cross section production of the R(3520) for the decay mode p π− π− K+ K0 S were calculated to be 25 fb/GeV (36 fb/ GeV) with the 1 MeV/c2 (7 MeV/c2) width. For the decay mode p π− K+ K∗− the upper limits on the total cross section were 62 fb/GeV/c (83 fb/ GeV/c) for the 1MeV/c2 (7 MeV/c2) width hypotheses. This shows that the nonobservance of the state was unaffected by the condition that the baryon number was conserved in the event. The thesis also investigates the feasibility of using a new evolutionary algorithm, Gene Expression Programming, for an event selection problem relevant for the physics analysis presented here. The new methods allowed automatic identification of selection criteria similar to those based on cuts applied on event variables. This showed the feasibility of the new method

Secara umum, aljabar dengan realisasi genetik bersifat komutatif tetapi bersifat non-assosiatif. Jika individu P kawin dengan Q dan hasilnya dikawinkan dengan R, hasil perkawinannya tidak akan sama dengan individu P dikawinkan dengan hasil perkawinan individu Q dengan R, atau dengan kata lain nbsp;(non-assosiatif). Sedangkan jika individu P dikawinkan dengan individu Q hasilnya akan sama dengan indivdu Q dikawinkan dengan individu P atau nbsp;(komutatif).

Effects of pesticide mixtures in human and animal models: an update of the recent literature
No full textThis review aims to provide an update on our current knowledge of the various effects of pesticide cocktails. We have collected data from studies conducted in mammalian models in vitro and in vivo that was published between 2000 and 2014. All ecotoxicological studies were voluntarily excluded. Cocktail effects were classified according to how they had been classified by each author. The frequency of the various cocktail effects and the classes and chemical families of pesticides involved in the observed effects were assessed. When focusing on the function of pesticides (i.e. herbicide, insecticide or fungicide), 46% of the mixtures contained insecticides alone, 15% fungicides alone, and 4.5% herbicides alone. Mixtures with effects associated with neurotoxicity were mainly composed of insecticides, and most studies on the effects of fungicide mixtures (90%) were associated with effects on endocrine regulation and/or reproduction. Dose addition was observed with each kind of mixture except herbicide combinations. In contrast, synergic interactions or greater-than-additive effects were mainly reported for insecticide mixtures. There were few examples of potentiating and antagonistic interactions. We have identified chemical families of compounds specifically involved in synergy, addition, potentiation and antagonism, and those that do not interact when combined. The chemical families identified as being involved in synergy are in agreement with data from another recently published compilation of ecotoxicological studies. For most mixtures investigated, further validation data is still needed from experiments using other compounds and other experimental models but this update provides useful information to help in human health risk assessments
Stuckey, Slave Culture - Nationalist Theory and the Foundations of Black America
No full textSlave Culture is a stimulating and well researched study into the social history of black America since the early colonial period up to the late 1930s. Professor Stuckey writes with the ease and clarity rarely found in more recent texts of black history. Slave Culture provides meaningful elaboration and examination of black society both in pre- and post-slavery America. In addition to an indepth overview of black culture and society, the author provides the reader with useful and relevant case studies of selected black Americans. The major figures included in the book are David Walker, Henry Highland Gamet, W.E.B. DuBois, and Paul Robeson
Turbulent Properties of Stationary Flows in Porous Media
No full textInternational audienceIn this study, we investigate the flow dynamics in a fixed bed of hydrogel beads using particle trackingvelocimetry to compute the velocity field in the middle of the bed for moderate Reynolds numbers(Re = 124, 169, 203, 211). We discover that even though the flow is stationary at the larger scales, itexhibits complex multiscale spatial dynamics reminiscent of those observed in classical turbulence. Wefind evidence of the presence of an inertial range and a direct energy cascade, and are able to obtain a valuefor a “porous” Kolmogorov constant of C2 = 3.1 + ou - 0.3. This analogy with turbulence opens up newpossibilities for understanding mixing and global transport properties in porous media
