Let L be a line bundle on a K3 or Enriques surface. We give a vanishing theorem for H(L) that, unlike most vanishing theorems, gives necessary and sufficient geometrical conditions for the vanishing. This result is essential in our study of BrillNoether theory of curves on Enriques surfaces [KL1] and of Enriques-Fano threefolds [KLM].

We demonstrate frequency-resolved optical gating (FROG) for measuring the full intensity and phase of several-optical-cycle 1.5-m pulses generated from a Kerr-lens mode-locked (KLM) Cr4+:YAG laser. This involves the use of an angle-dithered second-harmonic-generation crystal to achieve the full pulse bandwidth despite the use of a relatively thick nonlinear crystal.

The environment in which airlines operate is uncertain for many reasons, for example due to the effects of weather, traffic or crew unavailability (due to delay or sickness). This work focuses on airline reserve crew scheduling under crew absence uncertainty and delay for an airline operating a single hub and spoke network. Reserve crew can be used to cover absent crew or delayed connecting cre...

We use identification robust tests to show that difference (Dif), level (Lev), and nonlinear (NL) moment conditions, as proposed by Arellano Bond (1991, Review of Economic Studies 58, 277–297), Ahn Schmidt (1995, Journal Econometrics 68, 5–27), Bover 29–51), Blundell (1998, 87, 115–143) for the linear dynamic panel data model, do not separately identify autoregressive parameter when its true va...

To distinguish between random and non-random sequence, Kolmogorov and Martin-Löf proposed a new definition of randomness, according to which an object (e.g., a sequence of 0s and 1s) if random if it satisfies all probability laws, i.e., in more precise terms, if it does not belong to any definable set of probability measure 0. This definition reflect the usual physicists’ idea that events with ...

We propose a self-consistent approximate solution of the disordered Kondo-lattice model (KLM) to get the interconnected electronic and magnetic properties of ’local-moment’ systems like diluted ferromagnetic semiconductors. Aiming at (A1−xMx) compounds, where magnetic (M) and non-magnetic (A) atoms are distributed randomly over a crystal lattice, we present a theory which treats the subsystems ...

Relative dielectronic-recombination cross sections for hydrogenlike argon are presented. The contributions of the KLL, KLM, KLN, KLO, and KLP groups of resonances are compared to theoretical calculations. The experimental method consists of the formation and interaction of ions with electrons in an ion trap followed by an analysis of the extracted ions to determine relative yields. Comparison w...
