OBJECTIVES To examine the extent to which chronic sleep curtailment from infancy to mid-childhood is associated with total and central adiposity. METHODS We studied 1046 children participating in a prospective cohort study. At age 6 months and yearly from age 1 to 7 years, mothers reported their children's sleep duration in a usual 24-hour period. The main exposure was a sleep curtailment sco...

BACKGROUND Given their length, commonly used scales to assess suicide risk, such as the Beck Scale for Suicide Ideation (SSI) are of limited use as screening tools. In the current study we tested whether deterministic and stochastic curtailment can be applied to shorten the 19-item SSI, without compromising its accuracy. METHODS Data from 366 patients, who were seen by a liaison psychiatry se...

The electric power grid has evolved significantly over the past two decades in response to climate change. Increased levels of renewable energy generation, as a prominent feature this evolution, have led new congestion patterns transmission network. system is originally designed for conventional sources, with predictable flow patterns. Insufficient transfer capability congested systems results ...

The dispatch-down of excess wind energy is a growing concern, especially for countries integrating high levels variable renewable energy. Demand flexibility presents an opportunity to move consumers loads periods energy, which could provide numerous values the system. While previous research has focused on managing curtailment (a system-wide issue), much rejected due constraint local issue) and...

Unprecedented amounts of information from millions of smart meters and thermostats installed in recent years has left the door open for better understanding, analyzing and using the insights that data can provide, about the power consumption patterns of a building. The challenge with using data-driven approaches, is to close the loop for near real-time control and decision making in large build...

A method to perform distribution grid power flow calculations using stochastic load profiles and meteorological data is presented in this paper. The method is based on two previously presented algorithms: The first algorithm generates stochastic household load profiles and the second generates stochastic irradiance data, both using a sampling rate of one minute. Applying this data to an electri...
