CASSCF/MRCI/aug-cc-pVQZ~no g! and RCCSD~T!/aug-cc-pVQZ potential energy functions were reported for the à B1 and X̃ A1 states of CF2 , respectively. Vibrational wave functions of the symmetric stretching and bending modes of the two states of CF2 were obtained in variational calculations, employing Watson’s Hamiltonian for a nonlinear molecule and anharmonic vibrational wave functions expressed ...

This paper reviews major issues in the implementation of e-manufacturing, particularly the design aspects. It will examine recent progress, drawing out particular issues that are being addressed. Use will be made of the work by the author and colleagues to devise rule-based design and Internet-based control of machines to illustrate how these developments affect the integrated e-manufacturing e...

Design spectrum is known as an essential tool in earthquake engineering for calculation of maximum (design) responses in a structural system. Soil-structure interaction (SSI), as a phenomenon of coupling of responses of a structure and its underlying soil, was explored after introduction of design spectra and has not been taken into account in developing a design spectrum traditionally. To cons...

With a few exceptions, the micro total analysis systems (mTASs) currently available have failed to live up to the ideal of the miniaturization of multiple laboratory operations onto a single chip. These systems perform sample preparation off chip and only pursue a single function. Hence, the definitive challenge is to interface the processing of real-world biological samples with downstream app...

Limb dystonia can occur in primary dystonias or as a complication in neurodegenerative diseases e.g. Huntington’s disease, Wilson’s disease or Parkinson syndromes or other diseases like structural brain damage, peripheral trauma or drug-induced. Any muscle group under voluntary control can be affected, dystonic muscle overactivity can occur during rest, be aggravated by movement, or occur only ...

This paper addresses the problem of incorporating cognitively salient landmarks in computer-generated navigation instructions. Based on a review of the existing literature in the domain of navigation with landmarks, the paper develops algorithms for generating routing instructions that include references to landmarks. The most basic algorithm uses a new weighting model to annotate simple routes...

Threats to biodiversity outpace the resources of the conservation community and necessitate careful prioritization of conservation actions. I suggest that targeting the regions where biogeographic assemblages intersect—“biogeographic crossroads”—is a strategy that may achieve significant conservation economy by focusing on areas that satisfy many conservation criteria. I used a combination of d...
