BACKGROUND This paper reports day-to-day data for from a one-week intervention phase, part of a 9-weeks randomised parallel study with patient having major depression (data from weekly visits have been reported). Wake therapy (sleep deprivation) has an established antidepressant effect with onset of action within hours. Deterioration on the following night's sleep is, however, common, and we us...

Island thermal effects on the trail cloud band over the central North Pacific are investigated for the lee of Hawaii using satellite observations and a regional atmospheric model. The trail cloud band develops around noon and peaks in cloudiness in the early afternoon. The analysis of numerical simulations of the Kauai wake suggests that a dynamically induced convergence zone forms in the lee o...

This paper presents a study on the effect of wake modeling on the prediction of the off-axis response to pilot inputs for a hingeless and an articulated rotor helicopter, including a comparison with flight test data. The free wake model can capture geometry changes due to maneuvering flight. The prediction of the response to pilot inputs improves only slightly; in particular, the off-axis respo...

The modified analytical form for the longitud inal and transverse resistive wake potentials of pointlike charge moving parallel to the axis of round pipe with frequency independent walls conductivity is obtained. The short range wake potentials are presented by uniformly converged series. For the frequency dependent conductivity, the resonator term of the longitudinal monopole wake potential is...

While numerous studies have shown that a night of sleep profits memory relative to wake, we still have little understanding about what factors mediate this effect of sleep. A clear understanding of the dynamics of this effect of sleep beyond the initial night of sleep is also lacking. Here, we examined the effect of extrinsic rewards on sleep-dependent declarative memory processing across 12 an...

This paper describes an experimental investigation into the development of a planar turbulent wake under constant adverse and favorable pressure gradient conditions. The focus of the study is on the near-wake due to its relevance to high-lift systems for commercial transport aircraft. The wake is generated by a flat splitter plate with tapered trailing edge. The pressure gradients are imposed a...

The 1.7-GeV 100-mA CW proton linac is now under design for the Accelerator Production of Tritium (APT) Project [1]. The APT linac comprises both the normal conducting (below 211 MeV) and superconducting (SC) sections. The high current leads to stringent restrictions on allowable beam losses (< 1 nA/m), that requires analyzing carefully all possible loss sources. While wake-field effects are usu...

Smart home technologies provide numerous benefits for providing healthcare to individuals in a non-invasive manner. Our goal of this research is to use smart home technology to assistance people recovering from injuries or coping with disabilities to live independently. In this paper, we propose an algorithmic method, Behavior Forecasting (BF), to model and forecast both the wake and sleep beha...
