Interplanetary scintillation observations of the solar wind close to the Sun and out of the ecliptic [PDF]

, 1983
A brief review is given of recent developments in the observation of the solar wind by the method of interplanetary scintillation. The emphasis is on observations of the velocity structure, the electron density and the effect of propagating disturbances ...

Disturbance Ecology in the Anthropocene

Frontiers in Ecology and Evolution, 2019
With the accumulating evidence of changing disturbance regimes becoming increasingly obvious, there is potential for disturbance ecology to become the most valuable lens through which climate-related disturbance events are interpreted.

Use of waveform lidar and hyperspectral sensors to assess selected spatial and structural patterns associated with recent and repeat disturbance and the abundance of sugar maple (Acer saccharum Marsh.) in a temperate mixed hardwood and conifer forest. [PDF]

, 2011
Waveform lidar imagery was acquired on September 26, 1999 over the Bartlett Experimental Forest (BEF) in New Hampshire (USA) using NASA\u27s Laser Vegetation Imaging Sensor (LVIS).

Analysis of a global Moreton wave observed on October 28, 2003

, 2009
We study the well pronounced Moreton wave that occurred in as- sociation with the X17.2 are/CME event of October 28, 2003. This Moreton wave is striking for its global propagation and two separate wave centers, which implies that two waves were launched ...

Topical cyclone rainfall characteristics as determined from a satellite passive microwave radiometer [PDF]

Data from the Nimbus-5 Electrically Scanning Microwave Radiometer (ESMR-5) were used to calculate latent heat release and other rainfall parameters for over 70 satellite observations of 21 tropical cyclones in the tropical North Pacific Ocean.

Impact of sleep disturbances on outcomes in intensive care units

Critical Care
Abstract Background Sleep deprivation is common in ICUs and may alter respiratory performance. Few studies have assessed the role of sleep disturbances on outcomes in critically ill patients. Objectives We hypothesized that sleep disturbances may be associated with poor outcomes in ICUs.

Functional leaf traits of understory species: strategies to different disturbance severities

Brazilian Journal of Biology
The specific leaf area (SLA) has been related to environmental disturbances, showing a positive correlation between the disturbances intensities and SLA in a plant community.

Patterns of diversity and regeneration in unmanaged moist deciduous forests in response to disturbance in Shiwalik Himalayas, India

Journal of Asia-Pacific Biodiversity, 2016
We studied vegetation attributes in Indian tropical moist deciduous unmanaged forests to determine the influence of forest disturbances on them. We enumerated 89 species: 72 under moderate disturbance and 54 under least disturbance.

Non-Stationary Random Process for Large-Scale Failure and Recovery of Power Distributions

, 2012
A key objective of the smart grid is to improve reliability of utility services to end users. This requires strengthening resilience of distribution networks that lie at the edge of the grid.
