Rhodamine D Q S Q Test Molecule in Intraocular Dynamics

Quantitative measurements of fluorescein in the eye are widely used in studying the function of the bloodretinal barrier, but they also can be of value in measuring the flow rate of the tears and aqueous humor and the barriers offered by the corneal layers and the other anterior structures of the eye. Concentrations down to 10~ g/ml can be determined in the ocular humors, and this allows measur...

The 3 He ( e , e ′ d ) p Reaction in ( q , ω ) - constant Kinematics

The cross section for the He(e, ed)p reaction has been measured as a function of the missing momentum pm in (q, ω)-constant kinematics at beam energies of 370 and 576 MeV for values of the three-momentum transfer q of 412, 504 and 604 MeV/c. The L(+TT), T and LT structure functions have been separated for q = 412 and 504 MeV/c. The data are compared to three-body Faddeev calculations, including...

On the Joint Distribution Of Selφ(E/Q) and Selφ(E ′/Q) in Quadratic Twist Families

Strikingly, this is not true when E has a single rational point of order two. In this case E has a degree two isogeny φ : E → E ′ and an associated Selmer group Selφ(E/Q). Work of Xiong shows that if E does not have a cyclic 4-isogeny de ned over Q(E[2]), then the distribution of the ranks of Selφ(E /Q) as d varies among the squarefree integers less than X tends to the distribution Max{0,N (0, ...

Complete arcs on the parabolic quadric Q(4, q)

Using the representation T2(O) of Q(4, q) and algebraic methods, we prove that complete (q2 − 1)-arcs of Q(4, q) do not exist when q = ph, p odd prime and h > 1. As a by-product we prove an embeddability theorem for the direction problem in AG(3, q). © 2007 Elsevier Inc. All rights reserved.
