Elliptic Flow of Identified Hadrons in Au+Au Collisions at sqrt(s_NN) = 200 GeV
The anisotropy parameter v_2, the second harmonic of the azimuthal particles
distribution, has been measured with the PHENIX detector in Au+Au collisions at
sqrt(s_NN) = 200 GeV for identified and inclusive charged particles at central
rapidities (|eta| < 0.35) with respect to the reaction plane defined at high
rapidities (|eta| = 3-4). The v_2 for all particles reaches a maximum at
mid-centrality, and increases with p_T up to 2 GeV/c and then saturates or
decreases slightly. Our results depart from hydrodynamically predicted behavior
above 2 GeV/c. A quark coalescence model is also investigated.Comment: 325 authors, 6 pages text, RevTeX, 3 figures, 0 tables. This version

Centrality Dependence of Direct Photon Production in sqrt(s_NN) = 200 GeV Au+Au Collisions
The first measurement of direct photons in Au+Au collisions at sqrt(s_NN) =
200 GeV is presented. The direct photon signal is extracted as a function of
the Au+Au collision centrality and compared to NLO pQCD calculations. The
direct photon yield is shown to scale with the number of nucleon-nucleon
collisions for all centralities.Comment: 329 authors, 6 pages text, 3 figures, 1 Table. Submitted to PRL.

Functional neurological disorder is a feminist issue
Functional neurological disorder (FND) is a common and disabling disorder, often misunderstood by clinicians. Although viewed sceptically by some, FND is a diagnosis that can be made accurately, based on positive clinical signs, with clinical features that have remained stable for over 100 years. Despite some progress in the last decade, people with FND continue to suffer subtle and overt forms of discrimination by clinicians, researchers and the public. There is abundant evidence that disorders perceived as primarily affecting women are neglected in healthcare and medical research, and the course of FND mirrors this neglect. We outline the reasons why FND is a feminist issue, incorporating historical and contemporary clinical, research and social perspectives. We call for parity for FND in medical education, research and clinical service development so that people affected by FND can receive the care they need
