This work deals with wavelength assignment for lightpaths. We restrict our attention to the near term, in which WDM networks will be in the form of rings and higher level networks will be SONET/SDH self-healing rings. This view changes the goal of wavelength assignment (WLA) vs. previous work on the subject in a number of aspects. First, a pair of SONET(More)
This paper considers grooming of low speed traf-c into high speed lightpaths in a WDM based optical ring with a primary goal of reducing the cost of the entire system, which is dominated by the cost of the SONET transmission equipment connected to the optical ring. The paper attempts to enumerate the architectural options provided by SONET to arrive at a(More)
Dog parks are very popular in urban areas, but there are no current studies attempting to correlate visits to dog parks and risk of colonization by enteric parasites. The purpose of this study was to determine whether dog park visitation is associated with an increased prevalence of enteric parasites or an increase in prevalence of gastrointestinal signs in(More)
The synthesis of the deoxynucleoside derived from the base P, 6H,8H-3,4-dihydro-pyrimido[4,5-c] [4,5-c] [1,2]oxazin-7-one, 2, and its introduction by established phosphoramidite and H-phosphonate chemistry into oligonucleotides is described. The melting transition temperatures (Tm) of a range of heptadecamer duplexes containing P/A and P/G base-pairs are(More)
The nucleosides N6-methoxy-2'-deoxyadenosine (dZ) and 2-amino-9-(2-deoxy-beta-ribofuranosyl)-6-methoxyaminopurine (dK) have been synthesised and converted into 5'-O-dimethoxytrityl 3'-(2-cyanoethyl N,N-diisopropylphosphoramidites). These monomers have been used in machine DNA synthesis to give a set of heptadecanucleotides containing up to three analogue(More)
Practical usability of the majority of current wearable body sensor systems for multiple parameter physiological signal acquisition is limited by the multiple physical connections between sensors and the data-acquisition modules. In order to improve the user comfort and enable the use of these types of systems on active mobile subjects, we propose a(More)

In order to reach a more detailed understanding of the mechanism of the mutagenic action of methoxyamine and of N4-methoxycytidine and its 2'-deoxyribo-analogue, the solution structures of the self-complementary octanucleotide, d(CGAATTCG) and its analogues, d(CGAATCCG), d(CGAATMCG) and d(CGAATPCG) (designated 8mer-AT, 8mer-AC, 8mer-AM, and 8mer-AP,(More)
A novel optical polarimeter to sense the glucose level in vivo and noninvasively has been developed in the Institute of Radiological Science, National Yang Ming University. A 30-minute delay between the aqueous glucose and the blood glucose was observed in rabbit's eyeball. Currently, aqueous glucose in low concentration is being tested and discussed.
Heptadecaoligodeoxyribonucleotides containing one or more of the bases, 6H,8H-3,4-dihydropyrimido[4,5-c][1,2]oxazin-7-one (P), 2-amino-6-methoxyaminopurine (K), and hypoxanthine (I) and combinations of P with K and I have been synthesised on a DNA synthesiser. The stability of duplexes containing these basemodified oligomers with P/A, P/G, K/C and K/T; P/A,(More)
