Grayanotoxin I Intoxication in Pet Pigs
Contaminated honey is a common cause of grayanotoxin intoxication in humans. Intoxication of animals, especially cattle, is usually due to ingestion of plants of the Ericaceae family, such as Rhododendron. Here, we report the ingestion of Pieris japonica as the cause of grayanotoxin I intoxication in 2 miniature pigs that were kept as pets. The pigs showed sudden onset of pale oral mucosa, tachycardia, tachypnea, hypersalivation, tremor, and ataxia that progressed to lateral recumbency. The pathological examination of one pig revealed no specific indications for intoxication except for the finding of plant material of Pieris japonica in the intestine. Grayanotoxin I was identified in the ingested plant, gastric content, blood, liver, bile, kidney, urine, lung, and skeletal muscle via HPLC-MS/MS. Grayanotoxin I should be considered as a differential etiological diagnosis in pigs with unspecific signs and discovery of ingested plant material as the only indication in the pathologic examination
Size reconstructibility of graphs
The deck of a graph is given by the multiset of (unlabelled) subgraphs
. The subgraphs are referred to as the cards of .
Brown and Fenner recently showed that, for , the number of edges of a
graph can be computed from any deck missing 2 cards. We show that, for
sufficiently large , the number of edges can be computed from any deck
missing at most cards.Comment: 15 page
Route Planning in Transportation Networks
We survey recent advances in algorithms for route planning in transportation
networks. For road networks, we show that one can compute driving directions in
milliseconds or less even at continental scale. A variety of techniques provide
different trade-offs between preprocessing effort, space requirements, and
query time. Some algorithms can answer queries in a fraction of a microsecond,
while others can deal efficiently with real-time traffic. Journey planning on
public transportation systems, although conceptually similar, is a
significantly harder problem due to its inherent time-dependent and
multicriteria nature. Although exact algorithms are fast enough for interactive
queries on metropolitan transit systems, dealing with continent-sized instances
requires simplifications or heavy preprocessing. The multimodal route planning
problem, which seeks journeys combining schedule-based transportation (buses,
trains) with unrestricted modes (walking, driving), is even harder, relying on
approximate solutions even for metropolitan inputs.Comment: This is an updated version of the technical report MSR-TR-2014-4,

A legal framework for a transnational offshore grid in the North Sea
A legal framework for a transnational offshore grid in the North Sea Most North Sea states consider offshore wind energy as a substantial contributor towards reaching their renewable energy targets. With the increasing number of offshore wind farms and the increasing distance from shore, the question of how to efficiently bring the electricity to shore is gaining importance. To date, the standard approach for transporting the energy to shore is to provide each wind farm with an individual park-to-shore cable. Due to the costs of submarine cables, the scarceness of acceptable cable routes and the potential conflicts with other users of the sea, new concepts are required
Triangular flow in event-by-event ideal hydrodynamics in Au+Au collisions at GeV
The first calculation of triangular flow in Au+Au collisions at
GeV from an event-by-event (3+1)-d
transport+hydrodynamics hybrid approach is presented. As a response to the
initial triangularity of the collision zone, is computed in
a similar way to the standard event-plane analysis for elliptic flow . It
is found that the triangular flow exhibits weak centrality dependence and is
roughly equal to elliptic flow in most central collisions. We also explore the
transverse momentum and rapidity dependence of and for charged
particles as well as identified particles. We conclude that an event-by-event
treatment of the ideal hydrodynamic evolution starting with realistic initial
conditions generates the main features expected for triangular flow.Comment: 5 pages, 7 figures, two figures and discussion added, centrality
