Correlation analyses of ground-based acoustic-pressure measurements of noise from a tethered F-22A provide insights into the sound-field characteristics with position and engine condition. Time-scaled single-point (auto) correlation functions show that, to the side of the nozzle exit, the temporal-correlation envelope decays rapidly, whereas the envelope decays more slowly in the maximum radiat...

Low-rank matrix approximations are often used to help scale standard machine learning algorithms to large-scale problems. Recently, matrix coherence has been used to characterize the ability to extract global information from a subset of matrix entries in the context of these low-rank approximations and other sampling-based algorithms, e.g., matrix completion, robust PCA. Since coherence is def...

Larger size networks require DSM coherence protocols which scale well. Fault-tolerance in terms of high availability is required for data access and for uninterrupted DSM service since large-scale environments have a greater number of potentially malfunctioning components. We present a new class of coherence protocols for DSM systems whose instances o er highly available access to shared data a...

objectives: within the context of health-related quality of life studies, it was necessary to translate and evaluate the psychometric properties of the sf-12 health survey version 2. the aim of this study was to investigate the factorial structure, convergent validity and reliability of this instrument in a healthy iranian sample, following translation and establishment of content and face vali...

The nervous breakdown of a 22-year-old, young woman was caused by severe sexual abuse in childhood, which was repressed over many years. During therapy, the patient accumulated resources to start the painful integration of these old traumas. Using holistic existential therapy in accordance with the life mission theory and the holistic process theory of healing, she finally was able to confront ...

Quality of life, health, and ability are often lost at the same time and most often in one decaying existential movement over 5 or 10 years. This "loss of life" is mostly too slow to be felt as life threatening, but once awakened to reality, it provokes the deepest of fears in patients: the fear of death itself and destruction of our mere existence. The horrible experience of having "lost life"...

BACKGROUND The aim of the study was to investigate nurses' and care workers' experiences of spiritual needs among residents with dementia in nursing homes. Nurses claim to practice holistic nursing. Nevertheless, there is little knowledge about how to recognise spiritual needs in residents with dementia. METHODS The study was conducted using a qualitative method with an exploratory design. Ei...

Conventional imaging modalities are unable to depict the early degeneration of articular cartilage in osteoarthritis, especially in small joints. Optical coherence tomography has previously been used successfully in high-resolution imaging of cartilage tissue. This pilot cadaver study demonstrates the use of intra-articular optical coherence tomography in imaging of articular cartilage of the f...
