When physicist Tim Berners-Lee and a team of fellow scientists at the European Center for High Energy Physics (CERN) launched the first-ever Web site in 1989, their goal was to make it easier for scie...
The Magellanic Clouds Survey: a Bridge to Nearby Galaxies
Nearby Galaxies Magellanic Clouds
2014/12/22
We outline to the community the value of a Magellanic Clouds Survey that consists of three components: I) a complete-area, high resolution, multi-band UV-near-IR broadband survey; II) a narrowband sur...
Riparian and Riverine Wildlife Response to a Newly Created Bridge Crossing
Great Blue Heron Road Effects Small Mammals Songbirds Waterbirds
2013/3/8
Construction of man-made objects such as roads and bridges can influence wildlife presence and abundance. We investtigated waterbirds, songbirds, anurans, turtles, small mammals, and furbearers along ...
Twisted Alexander polynomials of 2-bridge knots
Twisted Alexander polynomials 2-bridge knots Geometric Topology
2012/6/30
We investigate the twisted Alexander polynomial of a 2-bridge knot associated to a Fox coloring. For several families of 2-bridge knots, including but not limited to, torus knots and genus-one knots, ...

Epimorphisms 2-bridge link groups Group Theory
2012/6/18
We describe all upper-meridian-pair-preserving epimorphisms from 2-bridge link groups onto even Heckoid groups.
Spontaneously Broken Erlangen Program Offers a Bridge Between the Einstein and the Yang-Mills Theories
gravitation Erlangen Program Yang-Mills Einstein
2012/5/31
We shall give dynamics to our spacetime manifold by first identifying the local affine symmetry as the characterizing symmetry for our geometry \'a la Felix Klein, and then by prescribing 16 gauge vec...
In an attempt to increase social and economic development in the South East Asian countries of Lao People’s Democratic Republic (PDR), Thailand and Vietnam, efforts began to build a Second Internation...

Rye has already proven to be a good donor of genes for improving important traits and diversity in wheat breeding. The agronomic advantages of wheat-rye translocations, as well as their detrimental pl...
The Wartime Bridge Reliability Evaluation Model Based on Birth-and-Death Process
Wartime Bridge Reliability Evaluation Birth-And-Death Process
2013/1/30
At first, the concept of bridge reliability is given, followed with its mathematic model. Then, based on the analysis about the mechanism of the damage and repair of bridges, and the state diversion o...
de Broglie waves as the "Bridge of Becoming" between quantum theory and relativity
de Broglie waves quantum theory and relativity quantum level
2011/8/16
Abstract: It is hypothesized that de Broglie's 'matter waves' provide a dynamical basis for Minkowski spacetime in an antisubstantivalist or relational account. The relativity of simultaneity is seen ...
Classification of 3-bridge spheres of 3-bridge arborescent links
3-bridge spheres 3-bridge arborescent links Geometric Topology
2011/8/26
Abstract: In this paper, we give an isotopy classification of 3-bridge spheres of 3-bridge arborescent links, which are not Montesinos links. To this end, we prove a certain refinement of a theorem of...
