Dear Editor, Retinal artery occlusion (RAO) is characterized by attenuated arterioles and ischemic retinal opacity, which suggest retinal infarction. Branch RAO (BRAO) has a more favorable prognosis than central RAO (CRAO). CRAO and BRAO can be differentiated based on the isch-emic retinal opacity area, location of the attenuated vessels , and a cherry-red spot [1]. However, we encountered a ca...

The purpose of this study was to assess the degree, time sequence, and biochemical correlates of hypothermic protection against ischemic acute renal failure. Rats subjected to 40 minutes of bilateral renal artery occlusion (RAO) were made mildly hypothermic (32 degrees-33 degrees C, by cold saline peritoneal lavage) during the following time periods: 1) RAO only, 2) reperfusion only (beginning ...

In this paper we derive a canonical lower bound for the autocovariance function of any unbiased transfer-function estimator. As a generalization of the Cramér-Rao bound, the Cramér-Rao kernel that we define can be derived without parametrizing the model set. The Cramér-Rao kernel is thus one of the cornerstones for experiment design formulations that do not depend on the choice of coordinates.

In this paper, we study the geometry induced by Fisher-Rao metric on parameter space of Dirichlet distributions. We show that is geodesically complete and has everywhere negative sectional curvature. An important consequence curvature for applications Fr{\'e}chet mean a set distributions uniquely defined in geometry.

Multiple antennas arrays combined with high carrier frequencies play a key role in wireless networks for communications but also localization and sensing applications. To understand the fundamental limits of electromagnetically large antenna localization, this paper combines wave propagation theory estimation theory, computes Cramér-Rao Bound (CRB) source position on basis three Cartesian compo...

Acute renal failure can result from many conditions, in which artery stenosis (RAS) or obstruction (RAO) be corrected with appropriate interventional surgical procedures. The directly depicted currently available ultrasound (US) scanners. Therefore, we determine if there is RAS RAO patients poor function using US. However, are few reports about the utility of US excluding obstruction. purpose t...

nature neuroscience • volume 2 no 1 • january 1999 79 Neurons that respond optimally to line segments of a particular length were first reported in early studies of the cat and monkey visual cortex1,2. These neurons, which are especially abundant in cortical layers 2 and 3, have the curious property of endstopping (or end-inhibition): a vigorous response to an optimally oriented line segment is...
