Specific labeling of a single row of cellulose-synthesizing complexes (terminal complexes, TC subunits, TCs, or TC arrays) in Acetobacter xylinum by antibodies raised against a 93-kDa protein (the cyclic dignanylic acid-binding protein) has been demonstrated by using the sodium dodecyl sulfate (SDS)-freeze-fracture labeling (FRL) technique. The antibodies(More)
A total of 1,110 decamer primers were screened for RAPD markers linked to a dominant allele in hazelnut ( Corylus avellana) that confers resistance to eastern filbert blight caused by Anisogramma anomala. Twenty RAPD markers linked in coupling, and five markers linked in repulsion, were found. A seedling population was used to construct a linkage map of the(More)
This paper discusses the development of a high-accuracy endpointing algorithm for the emitter etch of a heterojunction bipolar transistor HBT. Fabrication of high-performance HBT's using self-aligned base-emitter processes requires etching through the emitter layer and stopping with very high accuracy on the base layer. The lack of selectivity in dry(More)
This study evaluated whether statin therapy increases the risk of herpes zoster (HZ) infection in Asia. This retrospective cohort study used the Longitudinal Health Insurance Database (LHID2000). From the LHID2000, patients aged 20 years were divided into two cohorts according to their statin use and were matched at a 1:1 ratio according to propensity(More)
To improve graphene-based multifunctional devices at nanoscale, a stepwise and controllable fabrication procedure must be elucidated. Here, a series of structural transition of bismuth (Bi) adatoms, adsorbed on monolayer epitaxial graphene (MEG), is explored at room temperature. Bi adatoms undergo a structural transition from one-dimensional (1D) linear(More)
OBJECTIVES Tuberculosis (TB) was a major cause of morbidity and mortality in Canada early in the 20th century. Elderly populations in Canada remain at high risk for TB disease. Elderly patients may present atypically, with the result that many active cases can remain undiagnosed. We present an outbreak of TB that occurred in a Residential and Long-Term Care(More)
Liquid crystalline materials comprised of a cyclic ring core and pendant triphenyl groups have been prepared. Differential scanning calorimetry (DSC) and polarized optical microscopy (POM) were utilized to identify the presence of the mesophases. X-ray diffraction (XRD) techniques confirmed that these liquid crystalline materials were discotic. The(More)
