A. (Charlotte) Flagg, Albion, New York. The dates of these letters are from 5 October 1918 to 11 April 1919.His letters are written on American Expeditionary Forces stationery. He writes about how the French live, the weather, states he is "responsible for the training of 2000 men," and about the war. He states that he has not been feeling well, and the doctors are not sure why. He also mentions that he may be coming home soon.Biographical/Historical Note: Rollin A. Flagg, born 10 January 1859, at Chautaugua, New York, married Charlotte Griswold in Albion, New York on 25 June 1890. They had three children, one of which was Kenyon Putnam Flagg, born 3 April 1892. Kenyon P. Flagg married Janette Maria Sutton at Fort Strong, Boston, Massachusetts on 27 July 1918. He was with the American Expeditionary Forces in France as a First Lieutenant, 77th Regiment, Coast Artillery
Limit shapes from harmonicity: dominos and the five vertex model
No full textWe discuss how to construct limit shapes for the domino tiling model (square
lattice dimer model) and -vertex model, in appropriate polygonal domains.
Our methods are based on the harmonic extension method of [R. Kenyon and I.

The O-specific polysaccharide structure and biosynthetic gene cluster of Yersinia pseudotuberculosis serotype O:11
No full textIn the Yersinia pseudotuberculosis serotyping scheme, 21 serotypes are present originating from about 30 different O-factors distributed within the species. With regard to the chemical structures of lipopolysaccharides (LPSs) and the genetic basis of their biosynthesis, a number, but not all, of Y. pseudotuberculosis strains representing different serotypes have been investigated. In order to present an overall picture of the relationship between genetics and structures, we have been working on the genetics and structures of various Y. pseudotuberculosis O-specific polysaccharides (OPSs). Here, we present a structural and genetic analysis of the Y. pseudotuberculosis serotype O:11 OPS. Our results showed that this OPS structure has the same backbone as that of Y. pseudotuberculosis O:1b, but with a 6d-L-Altf side-branch instead of Parf. The 30 end of the gene cluster is the same as that for O:1b and has the genes for synthesis of the backbone and for processing the completed repeat unit. The 50 end has genes for synthesis of 6d-L-Altf and its transfer to the repeating unit backbone. The pathway for the synthesis of the 6d-L-Altf appears to be different from that for 6d-L-Altp in Y. enterocolitica O:3. The chemical structure of the O:11 repeating unit i
Organization of Kenyon cells in subdivisions of the mushroom bodies of a lepidopteran insect
No full textThe mushroom bodies are paired structures in the insect brain involved in complex functions such as memory formation, sensory integration, and context recognition. In many insects these centers are elaborate, sometimes comprising several hundred thousand neurons. The present account describes the mushroom bodies of Spodoptera littoralis, a moth extensively used for studies of olfactory processing and conditioning. The mushroom bodies of Spodoptera consist of only about 4,000 large-diameter Kenyon cells. However, these neurons are recognizably similar to morphological classes of Kenyon cells identified in honey bees, Drosophila, and cockroaches. The spodopteran mushroom body is equipped with three major divisions of its vertical and medial lobe, one of which, the gamma lobe, is supplied by clawed class II Kenyon cells as in other described taxa. Of special interest is the presence of a discrete tract (the Upsilon tract) of axons leading from the calyx, separate from the pedunculus, that innervates lobelets above and beneath the medial lobe, close to the latter's origin from the pedunculus. This tract is comparable to tracts and resultant lobelets identified in cockroaches and termites. The article discusses possible functional roles of the spodopteran mushroom body against the background of olfactory behaviors described from this taxon and discusses the possible functional relevance of mushroom body structure, emphasizing similarities and dissimilarities with mushroom bodies of other species, in particular the fruit fly, Drosophila melanogaster

Follis of Constans I
No full textThe obverse of this copper follis depicts a right facing bust of the Emperor Constans I (r. 337-350) wearing a laurel wreath. The bust is encircled by a Latin inscription.
The reverse of the follis depicts two soldiers standing facing each other. Between them there are two military standards. Each holds a reversed spear in one hand and rests the other on a shield on the ground. A Latin inscription encircles the soldiers.

No full textWe identified the neurons comprising the Drosophila mushroom body (MB), an associative center in invertebrate brains, and provide a comprehensive map describing their potential connections. Each of the 21 MB output neuron (MBON) types elaborates segregated dendritic arbors along the parallel axons of similar to 2000 Kenyon cells, forming 15 compartments that collectively tile the MB lobes. MBON axons project to five discrete neuropils outside of the MB and three MBON types form a feedforward network in the lobes. Each of the 20 dopaminergic neuron (DAN) types projects axons to one, or at most two, of the MBON compartments. Convergence of DAN axons on compartmentalized Kenyon cell-MBON synapses creates a highly ordered unit that can support learning to impose valence on sensory representations. The elucidation of the complement of neurons of the MB provides a comprehensive anatomical substrate from which one can infer a functional logic of associative olfactory learning and memory
Measurement of the flavour composition of dijet events in pp collisions at s√=7 TeV with the ATLAS detector
No full textThis paper describes a measurement of the flavour composition of dijet events produced in pp collisions at s√=7~TeV using the ATLAS detector. The measurement uses the full 2010 data sample, corresponding to an integrated luminosity of 39 pb−1. Six possible combinations of light, charm and bottom jets are identified in the dijet events, where the jet flavour is defined by the presence of bottom, charm or solely light flavour hadrons in the jet. Kinematic variables, based on the properties of displaced decay vertices and optimised for jet flavour identification, are used in a multidimensional template fit to measure the fractions of these dijet flavour states as functions of the leading jet transverse momentum in the range 40 GeV to 500 GeV and jet rapidity |y|<2.1. The fit results agree with the predictions of leading- and next-to-leading-order calculations, with the exception of the dijet fraction composed of bottom and light flavour jets, which is underestimated by all models at large transverse jet momenta. The ability to identify jets containing two b-hadrons, originating from e.g. gluon splitting, is demonstrated. The difference between bottom jet production rates in leading and subleading jets is consistent with the next-to-leading-order predictions
