The global evolutions of f oF2 anomalies were examined for three very intense geomagnetic storms, namely the Halloween events of October–November 2003 (Event X, 29–30 October 2003, Dst −401 nT; Event Y, 20–21 November 2003, Dst −472 nT), and the largest Dst storm (Event Z, 13–14 March 1989, Dst −589 nT). For Event X, troughs (negative storms) were clearly seen for high northern and southern lat...

In recent years, the frequency of dust storm is rising. Dust storm can impact the climate changes and cause great damages to people. It is very necessary to monitor the disasters accurately. In this paper, a dust storm process occurred in April, 2006 has been monitored. According to the reflect and absorb characteristic of dust storm, the scope of dust storm is extracted successfully;and the in...

The pervasive availability of streaming data is driving interest in distributed Fast Data platforms for streaming applications. Such latency-sensitive applications need to respond to dynamism in the input rates and task behavior using scale-in and -out on elastic Cloud resources. Platforms like Apache Storm do not provide robust capabilities for responding to such dynamism and for rapid task mi...

background and objectives: hyperthyroidism can occur with pregnancy. thyroid storm is a life-threatening exacerbation of hyperthyroidism. the mortality rate for thyroid storm remains surprisingly high at approximately 20%. case report: a 21-year-old primigravida woman presented at 25 weeks, with severe pre-eclampsia and uncontrolled hyperthyroidism was scheduled for emergency cesarean section. ...

The characteristics of seasons with enhanced East Coast winter storm and storm surge activity are identified from among a set of global atmospheric circulation indices and local land and sea surface temperature anomalies. Without regard for storm strength or surge potential, the most active East Coast winter storm (ECWS) seasons occur in association with El Niño events. There is also some indic...

We investigate the dynamical states of a two-dimensional network of Hindmarsh-Rose spiking neurons, in the vicinity of the current threshold where the single neuron becomes active. Each neuron is electrically coupled with neurons in its close neighborhood. The existence of multistable synchronization states is established and discussed. We also show that, provided adequate initial conditions, t...

In 2005, the US National Academies—the National Academy of Science, the National Academy of Engineering, the Institute of Medi cine, and the National Research Council—issued a report called Rising Above the Gathering Storm: Ener gizing and Employing America for a Brighter Economic Future.1 Reporting at the request of a bipartisan group in Congress, a 20-member panel of advisers to the nation on...
