1. INTRODUCTION A phenomenon is defined as any state or process known through the senses rather than by intuition or reasoning, and thus is an observable event, especially something special or unusual. Many geophysical phenomena can be observed and monitored using space-based and ground-based sensors or simulated in numerical models. Research studies on geophysical phenomena rely on the data co...

• Collaboration policy: Homeworks must be done individually, except where otherwise noted in the assignments. “Individually” means each student must hand in their own answers, and each student must write and use their own code in the programming parts of the assignment. It is acceptable for students to collaborate in figuring out answers and to help each other solve the problems, though you mus...

■ The purpose of this study was to relate a psycholinguistic processing model of picture naming to the dynamics of cortical activation during picture naming. The activation was recorded from eight Dutch subjects with a whole-head neuromagnetometer. The processing model, based on extensive naming latency studies, is a stage model. In preparing a picture’s name, the speaker performs a chain of sp...

The authors evaluated the NEO Personality Inventory-Revised (NEO-PI-R) as a predictor of dietary quality in 850 married couples, focusing on associations among each participant’s personality as a predictor of their own dietary quality and their spouses’ dietary quality. Diet was based on a modified version of the US Department of Agriculture Healthy Eating Index. Openness was associated with se...

■ This study tested the hypothesis that Williams syndrome, a rare genetic neurodevelopmental disorder with an unusual cognitive phenotype, involves spared abilities in the domain of understanding other minds. A group of retarded adults with Williams syndrome was compared to an age-, IQ-, and languagematched group of adults with Prader-Willi syndrome, another genetic disorder without the cogniti...

We present the first results of the hard (5-10 keV) ASCA GIS survey SHEEP (Search for the High Energy Extragalactic Population). We have analysed 149 fields covering an area of 39 deg 2 detecting 69 sources. Several of these appear to be associated with QSOs and Seyfert-1 galaxies but with hard X-ray spectra, probably due to high absorption (N H > 10 22 cm −2) Indeed, the hardness ratio analysi...

Recall that group communication provides a model of communication whereby a process can send a single message to a group of other processes. When such a message is sent to a predefined group of recipients (as opposed to all nodes on the network), we refer to the communication as multicast. Since a multicast is sent out to a specific group, it is important to have agreement on the membership of ...
