We present detailed semi-empiric models for rotational modulations observed in ultraviolet wind lines of B0.5 supergiant HD64760. We model the Rotational Modulation Regions (RMRs) with advanced 3-D radiative transfer calculations in the stellar wind and quantitatively fit the time-evolution of the Si iv λ1395 resonance line. We find that the RMRs are due to linearly-shaped narrow sector-like de...

We specify and prove an algorithm solving k-Exclusion, a generalization of the Mutual Exclusion problem. k-Exclusion requires that at most k processes be in the Critical Section (CS) at once; in addition, we require bounded exit, starvation freedom and fairness properties. The goal within this framework is to minimize the number of Remote Memory References (RMRs) made. Previous algorithms have ...

Although the amount of energy that males and females invest in reproduction is an integral component of theories explaining the evolution of particular mating strategies, few studies have actually determined the amount of energy that each sex allocates to reproduction. We compared how energy is expended by male and female Anolis carolinensis lizards during both the breeding and postbreeding sea...

With 207 million ha of forest covering 22% of its land area, China ranks fifth in the world in forest area. Rapid economic growth, climate change, and forest disturbances pose new, complex challenges for forest research and management. Progress in meeting these challenges is relevant beyond China, because China's forests represent 34% of Asia's forests and 5% of the worlds' forests. To provide ...

Recent research on mutual exclusion for shared-memory systems has focused on local spinalgorithms. Performance is measured using the remote memory references (RMRs) metric. Ascommon in recent literature, we consider a standard asynchronous shared memory model withN processes, which allows atomic read, write and compare-and-swap (short: CAS) operations.In such a model, the asympt...

We present a treebank conversion method by which we construct an RMRS bank for HPSG parser evaluation from the TIGER Dependency Bank. Our method effectively performs automatic RMRS semantics construction from functional dependencies, following the semantic algebra of (Copestake et al., 2001). We present the semantics construction mechanism, and focus on some special phenomena. Automatic convers...
