OBJECTIVES To evaluate the thicknesses of retinal nerve fiber layer (RNFL) and macula by fourier-domain (FD) optical coherence tomography (OCT) in non-diabetic patients with end-stage-renal-failure (ESRF) undergoing hemodialysis (HD). METHODS This is a prospective and observational study. Both eyes of 20 patients receiving HD (group 1) and 34 control patients (group 2) were evaluated by FD-OC...

Sample-average approximations (SAA) are a practical means of finding approximate solutions of stochastic programming problems involving an extremely large (or infinite) number of scenarios. SAA can also be used to find estimates of a lower bound on the optimal objective value of the true problem which, when coupled with an upper bound, provides confidence intervals for the true optimal objectiv...

Abstract. Let {Xn,n≥1} be a sequence of negatively superadditive dependent (NSD, in short) random variables and {ank,1≤ k≤n,n≥1} be an array of real numbers. Under some suitable conditions, we present some results on complete convergence for weighted sums ∑k=1ankXk of NSD random variables by using the Rosenthal type inequality. The results obtained in the paper generalize some corresponding one...

The present study examined the convergent validity of the Shedler-Westen Assessment Procedure Q-Sort (SWAP-200; ) dependency scales (Dependent Personality Disorder [DPD] Clinical Prototype and DPD composite description) by examining links between these variables with Inventory of Interpersonal Problems Circumplex Scales (IIP-C; Alden et al., 1990; Horowitz et al., 2000; Horowitz et al., 1988), ...

for all x, y ∈ R. Moreover, it follows that 1.2 implies 1.1 , and hence, 1.1 and 1.2 are equivalent. Ebrahimi and Ghosh 1 showed that 1.1 and 1.2 are not equivalent for a collection of 3 or more random variables. They considered random variables X1, X2, and X3 where X1, X2, X3 assumed the values 0, 1, 1 , 1, 0, 1 , 1, 1, 0 , and 0, 0, 0 each with probability 1/4. The random variables X1, X2, an...

In certain cells in the right upper quadrant of the abdominal ganglion of Aplysia depilans, a small excitatory post-synaptic potential (EPSP), produced by a weak stimulus to one pathway (test stimulus), underwent a prolonged facilitation when it was paired several times with a very strong stimulus to a second pathway (priming stimulus). In some cells this heterosynaptic facilitation was depende...

Previous neuroimaging studies provided evidence that visual mental imagery relies, in part, on the primary visual cortex. We hypothesized that, analogous to the finding that motor imagery increases the excitability of motor cortex, visual imagery should increase visual cortex excitability, as indexed by a decrease in the phosphene threshold (PT). In order to test visual cortex excitability, the...
