ions Abstractions have a cost. File systems and network protocols are generic and not tailored to one particular application. We cannot expect an abstraction to be optimal with respect to every application that uses it. Similarly on the PL side one cannot expect a general purpose PL to provide the exact abstractions needed for one particular application. These abstractions too have a cost: they...

objective: ecosystems with mixed species compared to the ones with pure compositions provide a broader range of options in the fields of biodiversity, conservation, protection and restoration. nearly all forest plantations are established as monocultures, but research has shown that there are potential advantages to be gained by using carefully designed species mixtures in place of monocultures...

background: this study has been conducted on workers from several workplaces where materials containing lead are used during december 2006-april 2007 in eskişehir, a city of the middle anatolian region of turkey. methods: the study and control groups were occured with 403, and 97 men, respectively. after each interview with the individuals, their blood pressures (bp) and complete blood counts (...

noise is defined as unwanted or objectionable sound. human susceptibility to noise varies in terms of intensity, altitude, timbre of sound, personal sensibility, age, and history of ear disorder. noise pollution which is the result of heterogeneous and uncontrolled developments of cities is one the serious problems in large cities of iran. although noise pollution in kerman (located in southeas...

low-level laser therapy (lllt) provides several benefits for patients receiving orthodontic treatment. according to some literatures, orthodontic tooth movement (otm) can be enhanced but some investigators have reported contradictory results. this article reviews the literature regarding the different aspects of the use of lllt on otm and its alterations. the general data regarding the study de...

introduction: tonsillectomy is among commonest otorhinolaryngologic surgeries. many methods have been used to control post surgical pain, but despite it, pain is still one of the problems related to this operation. recently, due to the non invasiveness of low level lasers, this modality has attracted attention. the purpose of this study is to evaluate the effects of low level laser irradiation ...

We construct models containing exactly one supercompact cardinal in which level by level inequivalence between strong compactness and supercompactness holds. In each model, above the supercompact cardinal, there are finitely many strongly compact cardinals, and the strongly compact and measurable cardinals precisely coincide. Say that a model containing supercompact cardinals satisfies level by...

Schema mappings and data mappings constitute essential building blocks of data integration, data exchange and peer-to-peer data sharing systems. At present, either schema-level mappings or datalevel mappings are used for data sharing purposes. In this paper we consider the semantics of bi-level mapping that combines the schema-level and data-level mappings. Tabular representation of the mapping...

We present a possible method for integrating high level and low level planning. To do so, we introduce the global plan random trajectory η0 : [1, T ] → R, measured by goals Gi and governed by the distribution p(η0 | {Gi}i=1). This distribution is combined with the low level robot-crowd planner p(f, f, . . . , f | z1:t) (from [Trautman et al., 2013, Trautman and Krause, 2010]) in the distributio...
