Quantification of infrared (IR) radiation is a convenient, noncontact method for making the base metal temperature measurements needed for on-line feedback controls. However, the problem of interference from the arc is a complicating factor in applying IR temperature sensing to welding. The objective of this research is to implement and test a top-face, noncontact temperature measurement system...

This paper introduces a special issue of the journal on the subject of Project Varenius, a three-year effort funded by the US National Science Foundation to advance geographic information science. Geographic information is first defined as an abstraction of primitive tuples linking geographic locations to general descriptors. Geographic concepts originate in the human mind, and are instantiated...

Background. This study is an attempt to combine and compare EEG, MEG and functional magnetic resonance imaging (FMRI) methods to map the somatotopic organization of primary somatosensory cortex. Methods. 32-channel EEG and 143-channel MEG recordings were acquired from two subjects during tactile stimulation of the fingertips. In addition, FMRI activation maps were produced during fingertip vibr...

A 57-year-old man was referred to the hospital because of fever and jaundice. The patient had been in good health until four years earlier, when a noninvasive, papillary transitional-cell carcinoma of the bladder, grade 1 on a scale of 1 to 3, was excised. Similar tumors were excised 12 and 18 months later. One year before admission, live bacille Calmette–Guérin (BCG) microorganisms were admini...

This article summarizes the practical and theoretical implications of 85 years of research in personnel selection. On the basis of meta-analytic findings, this article presents the validity of 19 selection procedures for predicting job performance and training performance and the validity of paired combinations of general mental ability (GMA) and the 18 other selection procedures. Overall, the ...

Apical constriction is a cell shape change that promotes tissue remodeling in a variety of homeostatic and developmental contexts, including gastrulation in many organisms and neural tube formation in vertebrates. In recent years, progress has been made towards understanding how the distinct cell biological processes that together drive apical constriction are coordinated. These processes inclu...
