Moderate severity disturbances, those that do not result in stand replacement, play an essential role ecosystem dynamics. Despite the prevalence of moderate disturbances and significant impacts they impose on forest functioning, little is known about their effects canopy structure how these differ over time across a range disturbance severities types. Using longitudinal data from National Ecolo...

Circles of Care grantees were provided the opportunity to develop a locally relevant definition of serious emotional disturbance that would be used to define what type of emotional, behavioral, and mental disability would be required to receive services. After conducting detailed assessments of the definition in the guidance for applicants GFA and the definitions used by others in their respect...

detection & classification of power quality (pq) disturbances are the most important problems in distribution systems. in this paper, a new approach for the detection and classification of single and combined pq disturbances is proposed which utilizes fuzzy logic and particle swarm optimization (pso) algorithms. in this approach, first suitable features of the waveform of pq disturbances ar...

In this paper, a new topology for Interline Dynamic Voltage Restorer (IDVR) is proposed. This topology contains two direct three-phase converters which have been connected together by a common fictitious dc-link. According to the kind of the disturbances, both of the converters can be employed as a rectifier or inverter. The converters receive the required compensation energy from the gird thro...

BACKGROUND As a first step toward developing effective strategies to control symptoms associated with head and neck cancer (HNC) and its treatment, we sought to describe the pattern of symptoms experienced before radiation therapy. METHODS Subjects completed the MD Anderson Symptom Inventory-Head and Neck Module before beginning radiation therapy. RESULTS In all, 270 patients participated. ...

Many natural and engineered biofilm systems periodically face disturbances. Here we present how the recovery time of a biofilm between disturbances (expressed as disturbance frequency) shapes the development of morphology and community structure in a multi-species biofilm at the landscape scale. It was hypothesized that a high disturbance frequency favors the development of a stable adapted bio...
