    Notes: We describe the construction and operation of a novel scanning tunneling microscope, which is capable of operating throughout a wide range of pressures (atmospheric—60 bar) and temperatures (300–650 K). The instrument has cylindrical symmetry and is constructed out of materials with low thermal conductivity and low coefficients of thermal expansion that allows imaging the same area over a wide temperature range. With this microscope we present images of the oxidation of polycrystalline nickel. © 2000 American Institute of Physics.

    Notes: The design and construction of a hypersonic waterjet apparatus is described. Jet velocities from 0.5 to 5 km/s have been achieved using a high explosive charge. Images are obtained in situ on various target substrates using a high-speed framing camera. Experimental results are shown for the impact of high velocity waterjets on propellants and high explosive samples. By observing the impact of the waterjet at a wide range of velocities a safety threshold can be determined where no reaction takes place. © 2001 American Institute of Physics.

    Notes: We present a simple, accurate, and nondestructive method to determine cantilever spring constants by measuring the resonant frequency before and after the addition of a thin gold layer. The method for resonating the cantilevers uses electrostatic force modulation, which has been described for conductive cantilevers, but we demonstrate it can also be applied to silicon nitride cantilevers. The variations in spring constant for cantilevers of the same type across the same wafer are also explored. © 2001 American Institute of Physics.

    Notes: Abstract. Dilated cardiomyopathy (DCM) is a common cause of morbidity and mortality, with 〉30% of cases being inherited. In one family with autosomal dominant familial dilated cardiomyopathy (FDCM), we localized the gene to the region of 10q21–10q23 and have performed candidate positional gene cloning. The peptidyl-prolyl-cis-trans-isomerase, mitochondrial precursor (PPIF: previously known as cyclophilin 3) is a protein that is part of the mitochondrial permeability transition pore, the activation of which is involved in the induction of necrotic and apoptotic cell death. Since it is encoded by a gene located within this FDCM critical region, PPIF was considered a potential candidate gene for FDCM. In order to screen patient genomes for evidence of disease-associated mutations, the genomic organization of this gene was determined. BAC libraries were screened by PCR, using primers designed from the published cDNA sequence, and positive clones were identified. This enabled the gene to be further localized to between the CEPH markers D10S1777 and D10S201. The DNA from a BAC clone was digested and subcloned into pUC18. Following identification of a subclone by whole-cell PCR, the gene was characterized by DNA sequencing; five introns were identified, and the sequences of the intron-exon boundaries were characterized. Additionally, 450 bp of DNA sequence upstream of the published cDNA were obtained and a potential transcription initiation site and promoter sequence were identified. DNA analysis of the entire PPIF coding region (including the intron-exon boundaries) of two affected and one unaffected family member revealed no mutations, therefore excluding this gene as the cause of FDCM in this family.

    Notes: Abstract DENEGOT is a distributed planning framework that bases conflict resolution on decentralized peer negotiation. Negotiation is viewed as a distributed search through potential compromises. The framework assumes that a satisficing solution is acceptable (a reasonable assumption in many complex domains). To estimate the quality of potential solutions, the negotiation search space is structured into a lattice of sets of potential compromise solutions based on hard constraints. A solution in a higher set in the lattice, if it is achievable, will be preferable over a solution in a lower set. Agents first search under the hard constraint level representing the highest quality solution standard achievable in the current situation. By relaxing hard constraints, the set of compromises that qualify as a solution are enlarged. Agents search for a resolution under the relaxed hard constraint set when a solution cannot be found under the current set of constraints. The framework consists of three iterative problem-solving phases: coordinated search, negotiation state analysis, and constraint relaxation. The application of the DENEGOT framework to distributed planning problems in two domains is demonstrated.
