Mixed-Criticality Scheduling with I/O [PDF]
This paper addresses the problem of scheduling tasks with different criticality levels in the presence of I/O requests. In mixed-criticality scheduling, higher criticality tasks are given precedence over those of lower criticality when it is impossible ...

Sporadic E responds to the 2022 Tonga volcano eruptions recorded by the Meridian Project
In this study, ionosonde observations over Fuke (19.5°N, 109.1°E), Wuhan (30.5°N, 114.4°E), and Mohe (53.5°N, 122.3°E) were analyzed to demonstrate the responses of the sporadic E () to the severe atmospheric disturbances caused by the Tonga volcanic ...

>E. coli -- sporadic case or an outbreak? [PDF]
Background and epidemiology: One of the many unfortunate consequences of the Walkerton tainted-water tragedy has been a lingering association of Escherichia coli O157:H7 with large-scale outbreaks. Lost somewhere among the lessons learned is an appreciation that E.

Three-dimensional metal ion flow in the polar ionosphere simulated by a new ionospheric model
The temporal evolution of the three-dimensional metal ion flow (MIF) is crucial for polar sporadic E layer dynamics. Yet, until now it has not been studied in detail.

Sporadic E in Middle Latitudes [PDF]
IN a recent paper, Layzer1 suggested that most middle latitude sporadic E layers are formed by discontinuities in the vertical motion of the neutral gas. Following his notation, w is the vertical velocity of ionization, and uz the neutral gas vertical velocity.

Quasi-stationary substructure within a sporadic E layer observed by the Low-Frequency Array (LOFAR)
Observations made with the Low-Frequency Array (LOFAR) have been used to infer the presence of variations in a sporadic E layer on a spatial scale of several kilometres and a temporal scale of ~10 min.

Ionospheric Recorders and Sporadic E [PDF]
It has been many times stated (Rawer 1949; Booker 1950; Booker and Gordon 1950; McNicol and Gipps 1951) that the frequency characteristics of the sporadic E region are rapidly varying functions of the overall sensitivity of the recording p'f equipment. A very simple test of this statement has been made; and it has been found to be incorrect at Brisbane.

ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.

IMF effect on sporadic-E layers at two northern polar cap sites: Part II – Electric field [PDF]
This paper is the second in a series on a study of the link between IMF and sporadic-E layers within the polar cap. In Paper I (Voiculescu et al., 2006), an analysis of the sporadic-E data from Thule and Longyearbyen was presented.
