A model is presented for the structure and properties of active centers in lone-pair semiconductors,
based on the possibility of unique bonding configurations which can arise from the …

The electrical and optical properties of materials which are characterized by narrow bands
in the vicinity of the Fermi energy are discussed. For such materials, electronic correlations …

The organophosphate cholinesterase inhibitor paraoxon is hydrolysed by serum
paraoxonase/arylesterase. A genetic polymorphism of paraoxonase (PON) activity which determines …

Purpose. Depressed employees are vulnerable to adverse work outcomes. We hypothesized
that work performance is impaired by depression and is worsened by exposure to …

It is now more than 15 years since the first demonstration of switching and memory devices
based on the amor phous semiconductors known as chalco genide glasses: glasses …

The War Powers Resolution (WPR) of 1973 is generally consid-ered the high-water mark of
congressional reassertion in national security af-fairs. In fact, it was ill conceived and badly …

Objective: This study assessed the relationship between depression severity and job
performance among employed primary care patients. Method: In a 2001–2004 longitudinal …

We discuss bias‐induced threshold switching in chalcogenide‐glass thin films, with an
emphasis on the unique aspects of this phenomenon. The electronic nature of both the ON state …

This paper characterizes the actual science performance of the James Webb Space Telescope
(JWST), as determined from the six month commissioning period. We summarize the …

OBJECTIVE:This study comprehensively assessed the work outcomes of employees with
depression. METHODS: We collected baseline and six-month follow-up survey data from 229 …
