Purpose: ‘This study describes hemodynamic characteristics of the retrobulbar circulation in ten eyes with acute anterior ischemic optic neuropathy (AION), in order to better understand Ihe natural history of this disease. Methods: Color Doppler imaging was used to measure the peak systolic blood flow velocities and vascular resistance (resistive index) within the central retinal, ophtalmic, an...

Heat shock transcription factor 1 (HSF1) is constitutively expressed in mammalian cells and negatively regulated for DNA binding and transcriptional activity. Upon exposure to heat shock and other forms of chemical and physiological stress, these activities of HSF1 are rapidly induced. In this report, we demonstrate that constitutive phosphorylation of HSF1 at serine residues distal to the tran...

Explore and critique Fowler and Christakis et al. work on social contagion of: images in Figure 1 generates a matrix of shortest network path distances from each node to all other nodes in the network and repositions nodes so as to reduce the sum of the difference between the plotted distances and the network distances (Kamada & Kawai, 1989). The fundamental pattern of ties in a social network ...

5 of 86 Single source optimal supply the potential at the nodes by solving the system of linear equations ik ! P lRkl"Uk #Ul$, then the currents through the links Ikl are determined. We use these currents to determine a first approximation of the optimal conductivities on the basis of the scaling relation. Then, the currents are recalculated with this set of conductivities, and the scaling rela...

We now turn to applications of our methods to real-world network data. Our first such example is taken from one of the classic studies in social network analysis. Over the course of two years in the early 1970s, Wayne Zachary observed social interactions between the members of a karate club at an American university "36#. He constructed networks of ties between members of the club based on thei...

We present the results of global VLBI observations at 6 cm wavelength of the X-ray binary LSI+61◦303 made at epoch 1992.4. During the course of our 24 hour VLBI observing session, the integrated flux measured simultaneously with the VLA indicated that the source was experiencing a minor flare, with the total flux rising and falling by ∼ 12 mJy. Our VLBI observations indicate that this brighteni...
