Physicians form a vital front in recognizing unusual clinical presentations that could herald a health threat. In the Flint water crisis, physicians can be credited with playing critical roles in both uncovering the crisis and providing leadership when government failed to respond effectively. Yet most physicians in Flint were not formally trained in advocacy or leadership and might have recogn...

Observations of the movements of air in underground passages have a long and fascinating history. Between 4000 and 1200 BC, European miners dug tunnels into chalk deposits searching for flint. Archaeological investigations at Grimes Graves in the south of England have shown that these early flint miners built brushwood fires at the working faces—presumably to weaken the rock. However, those Neo...

In this paper, we are interested in accurate acquisition and modeling of flint artefacts. Archaeologists needs accurate geometry measurements to refine their understanding of the flint artefacts manufacturing process. Current techniques require several operations. First, a copy of a flint artefact is reproduced. The copy is then sliced. A picture is taken for each slice. Eventually, geometric i...

In situ abrasion of shingle beach material is a neglected area of study in coastal geomorphology, with reduction in beach volumes normally attributed to longshore and offshore drift. Results from field abrasion experiments conducted on flint shingle beaches on the East Sussex coast, southern England, show that in situ reductions in volume of beach material may be more significant than has been ...

This manuscript presents an attempt to evaluate the intensity of fire through spatial patterning and thermoluminescence methodology. Previous studies of Layer II-6 Level 2 at the Acheulian site of Gesher Benot Ya'aqov suggested that hominins differentiated their activities across space, including multiple activities around a hearth reconstructed on the basis of the distribution of burned flint ...

We present an implementation in the functional programming language Haskell of the PLE decomposition of matrices over division rings. We discover in our benchmarks that in a relevant number of cases it is significantly faster than the C-based implementation provided in FLINT. Describing the guiding principles of our work, we introduce the reader to basic ideas from high performance functional p...

Landraces are valuable genetic resources for broadening the genetic base of elite germplasm in maize. Extensive exploitation of landraces has been hampered by their genetic heterogeneity and heavy genetic load. These limitations may be overcome by the in-vivo doubled haploid (DH) technique. A set of 132 DH lines derived from three European landraces and 106 elite flint (EF) lines were genotyped...

The dextrins, which occur as successive steps in the transition from glucose to starch and from starch to glucose, are so rarely detected in plant tissues and so ephemeral in existence, that their occurrence in stable form in matured or dormant tissues has seldom been reported. It has been the occasion of no little interest, therefore, to find that the sole carbohydrate in the endosperm of “wax...
