The galaxy giving rise to the damped Lyα absorbing system in the QSO OI 363 with z = 0.221 has been found. A galaxy which is probably associated with the second DLA in this same QSO at z = 0.0912 has also been found. Neither galaxy is very luminous, and neither galaxy shows signs of extensive current star formation, a massive disk or lots of gas. The impact parameters for each of the two galaxi...

Er3+/Yb3+ codoped tellurite-zinc-niobium (TZNb) glass was prepared by the melt-quenching method and used for the construction of a point all-fiber temperature sensor. The glass thermal stability and network structural properties were studied by differential thermal analysis and Raman spectrum, respectively. High glass transition temperature is beneficial to widen the working temperature range. ...

Optimal strategies in railway networks call for a differentiated treatment of fares, frequencies, and vehicle sizes in various links. However, for several reasons, railway operators may apply uniform levels for these decision variables. In this paper the authors investigate the welfare losses implied by uniform setting of fares per km, frequencies, or vehicle sizes. This is done within the cont...

Kingston (J Comb Theory (A) 20:357–363, 1976) and Anderson (J Comb Theory (A) 23:363, 1977) show that the probability that a given contestant wins a bestof-2k+1 series of asymmetric, zero-sum, binary-outcome games is, for a large class of assignment rules, independent of which contestant is assigned the advantageous role in each component game. We design a laboratory experiment to test this hyp...
