Learning to Generate Posters of Scientific Papers
Researchers often summarize their work in the form of posters. Posters
provide a coherent and efficient way to convey core ideas from scientific
papers. Generating a good scientific poster, however, is a complex and time
consuming cognitive task, since such posters need to be readable, informative,
and visually aesthetic. In this paper, for the first time, we study the
challenging problem of learning to generate posters from scientific papers. To
this end, a data-driven framework, that utilizes graphical models, is proposed.
Specifically, given content to display, the key elements of a good poster,
including panel layout and attributes of each panel, are learned and inferred
from data. Then, given inferred layout and attributes, composition of graphical
elements within each panel is synthesized. To learn and validate our model, we
collect and make public a Poster-Paper dataset, which consists of scientific
papers and corresponding posters with exhaustively labelled panels and
attributes. Qualitative and quantitative results indicate the effectiveness of
our approach.Comment: in Proceedings of the 30th AAAI Conference on Artificial Intelligence

Existence of solutions for fractional differential equations with three-point boundary conditions at resonance in
In this paper, by applying the coincidence degree theory which was first introduced by Mawhin, we obtain an existence result for the fractional three-point boundary value problems in , where the dimension of the kernel of fractional differential operator with the boundary conditions can take any value in . This is our novelty. Several examples are presented to illustrate the result

Giant mesoscopic spin Hall effect on surface of topological insulator
We study mesoscopic spin Hall effect on the surface of topological insulator
with a step-function potential. The giant spin polarization induced by a
transverse electric current is derived analytically by using McMillan method in
the ballistic transport limit, which oscillates across the potential boundary
with no confinement from the potential barrier due to the Klein paradox, and
should be observable in spin resolved scanning tunneling microscope.Comment: 5 pages, 3 figure
Half Metallic Bilayer Graphene
Charge neutral bilayer graphene has a gapped ground state as transport
experiments demonstrate. One of the plausible such ground states is layered
antiferromagnetic spin density wave (LAF) state, where the spins in top and
bottom layers have same magnitude with opposite directions. We propose that
lightly charged bilayer graphene in an electric field perpendicular to the
graphene plane may be a half metal as a consequence of the inversion and
particle-hole symmetry broken in the LAF state. We show this explicitly by
using a mean field theory on a 2-layer Hubbard model for the bilayer graphene.Comment: 4+ pages, 4 figure
Syntheses and luminescent properties of a series of new lanthanide azelates
A series of new lanthanide azelates [Ln(aze)(Haze)(H2O)]·H2O {Ln = La (1a), Ce (1b), Pr (1c); H2aze = azelaic acid}, [Ln2(aze)3(phen)2]·H2O [Ln = Nd (2a), Er (2b); phen = 1,10-phenanthroline], [Sm(aze)(Haze)(phen)]·2H2O (3), [Gd(aze)(phen)2]·ClO4 (4) and (Hphen)[Tb2(aze)2(phen)4]·3ClO4 (5) were hydrothermally prepared and structurally characterized.1a-c are isostructural and show 3-D framework based on 1-D infinite [Ln-O-Ln]n chain. 2a-b exhibit sql layer, while 3 displays 1-D chain, where phen ligands locate at both sides of the chain. The Ln3+ ions of 4 and 5 are connected by aze2− into two different types of rare cationic 1-D chains. The luminescent investigations show that both 2a and 2b exhibit interesting NIR luminescence and 5 displays a good potentiality as a luminescent sensor targeted for Fe3+ ion. Of particular interest, lanthanide azelates have not been to date documented, while this work presents the only examples of lanthanide azelates exhibiting luminescent properties. The magnetic properties of some lanthanide azelates were also investigated.publishe
5-Methyl-1,2,3,3a-tetraÂhydroÂbenzo[e]pyrroloÂ[2,1-b][1,3]oxazepin-10(5H)-one
The asymmetric unit of the title compound, C13H15NO2, the main product of a photoreaction, contains two crystallographically independent molÂecules. In both molÂecules, the conformation of the seven-membered ring is twist sofa and that of the five-membered rings is envelope. In the crystal, molÂecules are linked by weak interÂmolecular C—H⋯O hydrogen bonds
Localization of gauge field by non-minimal coupling with gravity
In this paper, we investigate the localization of the gauge field on
Randall-Sundrum-like braneworld models. The localization of the gauge
field is important because it plays a fundamental role in the branworld
theories. To achieve the localization, we propose a novel action with a
non-minimal coupling between the gauge field and gravity. We find that
the mass spectrum of the gauge field is continuous, without any gap between the
zero-mass mode and the massive modes, and except for the zero-mass mode all the
massive modes are not localized on the brane. Furthermore, the massive modes
have negative squared masses, indicating they are tachyonic. Our analysis can
be applied to a wide range of thin and thick braneworld scenarios, provided
that the five-dimensional spacetime is asymptotically anti-de Sitter.Comment: 10 pages, 2 figures, Accepted by JCA
