Multistrange baryon elliptic flow in Au plus Au collisions at root(NN)-N-S=200 GeV
We report on the first measurement of elliptic flow nu(2)(p(T)) of multistrange baryons Xi(-)+Xi(+) and Omega(-)+Omega(+) in heavy-ion collisions. In minimum-bias Au+Au collisions at root s(NN)=200 GeV, a significant amount of elliptic flow, comparable to other nonstrange baryons, is observed for multistrange baryons which are expected to be particularly sensitive to the dynamics of the partonic stage of heavy-ion collisions. The p(T) dependence of nu(2) of the multistrange baryons confirms the number of constituent quark scaling previously observed for lighter hadrons. These results support the idea that a substantial fraction of the observed collective motion is developed at the early partonic stage in ultrarelativistic nuclear collisions at the Relativistic Heavy Ion Collider
Visual Impairment
The past decade has witnessed a considerable upsurge of clinical and research interest in the problems of developmentally and physically the fields of psychology, disabled persons. Indeed, professionals from special education, rehabilitation, psychiatry, and social work have all directed attention to the development and implementation of evaluation and remedial programs. The heightened activity in this area is in part a result of early assessment research with these populations, which provided preliminary evidence of difficulties in social and emotional adjustment in many disabled individuals. In response to these findings, many intervention efforts have been implemented to deal with these issues and improve the life situation of the disabled. Also, there were indications that developmentally and physically disabled children often were deprived of adequate educations. As a result, legal and legislative initiatives have been enacted in recent years to make public education available to all students irrespective of disability. Central to all therapeutic and psychoeducational endeavors with the disabled is psychological evaluation. Only through careful and comprehensive psychological evaluation can areas of deficit as well as strengths be identified. Once treatment targets and goals have been ascertained, psychological evaluation is needed to determine the efficacy of intervention strategies. However, the field of psychological evaluation, in general, and with disabled persons, in particular, has become highly specialized. This is largely a function of the changing roles of psychological evaluators.https://nsuworks.nova.edu/cps_facbooks/1221/thumbnail.jp
Directed flow in Au+Au collisions at =62.4 GeV
We present the directed flow (v1) measured in Au+Au collisions at =62.4 GeV in the midpseudorapidity region |\eta|<1.3 and in the forward pseudorapidity region 2.5<|\eta|<4.0. The results are obtained using the three-particle cumulant method, the event plane method with mixed harmonics, and for the first time at the Relativistic Heavy Ion Collider, the standard method with the event plane reconstructed from spectator neutrons. Results from all three methods are in good agreement. Over the pseudorapidity range studied, charged particle directed flow is in the direction opposite to that of fragmentation neutrons
Longitudinal double-spin asymmetry and cross section for inclusive jet production in polarized proton collisions at square root of s = 200 GeV
We report a measurement of the longitudinal double-spin asymmetry A(LL) and the differential cross section for inclusive midrapidity jet production in polarized proton collisions at s=200 GeV. The cross section data cover transverse momenta 5 < p(T)< 50 GeV/c and agree with next-to-leading order perturbative QCD evaluations. The A(LL) data cover 5 < p(T)< 17 GeV/c and disfavor at 98% C.L. maximal positive gluon polarization in the polarized nucleon
