• A submitted manuscript is the author's version of the article upon submission and before peer-review. There can be important differences between the submitted version and the official published version of record. People interested in the research are advised to contact the author for the final version of the publication, or visit the DOI to the publisher's website. • The final author version ...
We examined forest structure, tree recruitment, and spatial pattern over a 130-year period on cinder soils in northern Arizona. Data were collected from a 3.24 ha permanent, stem-mapped plot established in 1909. This site is unique in that it represents ponderosa pine (Pinus ponderosa Laws. var. scopulorum Engelm.) growing on black cinder soils, which are of limited extent in the Southwest. Tre...

We present a preliminary search for D-D mixing using the decays D → Kππ, additionally presenting Dalitz-plot distributions and a measurement of the branching ratio for this mode. A new tagging technique is used to produce the doubly Cabibbo-suppressed Dalitz plot, which in turn is used to motivate the method used for the D-mixing search. We analyze 230.4 fb of data collected from the BABAR dete...
When creating interactive drama computer games then it is frequently useful to be able to generate a plot to use as a background for the drama and to use as a knowledge base for Non-Player Characters. In this article a new engine is proposed that dynamically creates new game plots for a murder mystery based game. The game engine uses Bayesian networks to create a new plot based on a probability...
A permanent assessment of climate regime in forest sites has a key role resource conservation and preservation ecosystem services, biodiversity landscape multi-functionality, informing sustainable management. In this view, time-series meteorological data relative to several monitoring from the ICP-Forest network Italy, were analyzed with aim define number site-specific observations, which can b...
In order to investigate the effect of vermicompost on physical and chemical properties of soil, an experiment was carried out in split plot based on complete randomized block design in three replications in Sari Agricultural Sciences and Natural Resources University. The physical and chemical properties of soil included bulk density, particle density, total porosity, water holding capacity, fie...
