A case-control comparison of immunologic and psychological parameters in the multiple chemical sensitivity syndrome. This letter is prompted by Rall's editorial on media and science in the January issue of EHP (102:10). Rall implies that bad reporting is being conducted concerning dioxin, CFCs, and asbestos. Rall concludes by assuming that he is correct in assigning a high level of risk to each...

All electronic circuits generally use inductive elements, such as transformers, coils, or relays, and some applications, such as stepper motors, also have inductive loads. Unfortunately, the failure of switching devices in inductive circuits is a frequent problem and causes system failure. Switchingtransistor and MOSFET failure is common in motor drivers, switched-mode power supplies, and simil...

data types have little impact on software error masking as far as we can determine Inheritance is not necessarily detrimental to error masking however when combined with information hiding it may become lethal Unit testing costs increase as the depth of inheritance increases This is directly related to the increase in the number of drivers and stubs As a counter argument subclasses tend to beco...

Most explanation schemes are reactive and informational: explanations are provided in response to specific user queries and focus on making the system’s reasoning more transparent. In mixed autonomy settings that involve teams of humans and autonomous agents, proactive explanation that anticipates and preempts potential surprises can be particularly valuable. By providing timely, succinct, and ...

adi it ion ally, the problems of Byzantine agreement, concensus, and interactive consistency are studied in a fully connected network with processors in malicious failure only. Such problems are re-examined with the assumption of malicious faults on both processors and links. The proposed protocols use the minimum number of message exchanges and can tolerate the maximum number of allowable faul...

Formal verification of integer multipliers was an open problem for a long time as the size of any reduced ordered binary decision diagram (BDD) [1] which represents integer multiplication is exponential in the width of the operands [2]. In 1995, Bryant and Chen [4] introduced multiplicative binary moment diagrams (*BMD) which is a canonical data structure for pseudo Boolean functions allowing a...
