The language RCC8 is a widely-studied formalism for describing topological arrangements of spatial regions. The variables of this language range over the collection of non-empty, regular closed sets of n-dimensional Euclidean space, here denoted RC(Rn), and its non-logical primitives allow us to specify how the interiors, exteriors and boundaries of these sets intersect. The key question is the...

We numerically study structural properties of mechanically stable packings of hard spheres (HS), in a wide range of packing fractions 0.53 ≤ ϕ ≤ 0.72. Detailed structural information is obtained from the analysis of orientational order parameters, which clearly reveals a disorder-order phase transition at the random close packing (RCP) density, ϕc ≃ 0.64. Above ϕc, the crystalline nuclei form 3...

This paper focuses on the possibilities of a Petri net based rapid control prototyping (RCP) tool chain. P/T nets extended by interfaces and connected to an extended state model allow the description of typical programmable logic controller tasks. After a general introduction to RCP, the method is applied to the area of sequential control, and code generation for the chosen model is depicted. T...

CONTEXT Physicians frequently prescribe respiratory treatments to hospitalized patients, but the influence of such treatments on clinical outcomes is difficult to assess. OBJECTIVE To compare the clinical outcomes of patients receiving respiratory treatments managed by respiratory care practitioner (RCP)-directed treatment protocols or physician-directed orders. DESIGN A single center, quas...

OBJECTIVES We retrospectively reviewed data of patients with incidental prostate cancer (PCa) who underwent radical cystoprostatectomy (RCP) for invasive bladder cancer and we analyzed their features with regard to incidence, pathologic characteristics, clinical significance, and implications for management. MATERIAL AND METHODS Clinical data and pathological features of 64 patients who under...

BACKGROUND A case finding strategy based on a number of established risk factors has been suggested by Royal College of Physicians' (RCP) guidelines to optimise bone densitometry referrals for assessment of osteoporosis. OBJECTIVE The performance of clinical referral criteria was examined in women and men aged <65 years referred for bone mineral density (BMD) assessment. STUDY DESIGN Cross ...

Many studies project future bird ranges by relying on correlative species distribution models. Such models do not usually represent important processes explicitly related to climate change and harvesting, which limits their potential for predicting and understanding the future of boreal bird assemblages at the landscape scale. In this study, we attempted to assess the cumulative and specific im...

OBJECTIVES The respiratory compensation point (RCP) marks the onset of hyperventilation ("respiratory compensation") during incremental exercise. Its physiological meaning has not yet been definitely determined, but the most common explanation is a failure of the body's buffering mechanisms which leads to metabolic (lactic) acidosis. It was intended to test this experimentally. METHODS During...
