The Ropelengths of Knots Are Almost Linear in Terms of Their Crossing Numbers
Yuanan Diao, Claus Ernst, Attila Por +1
For a knot or link K, let L(K) be the ropelength of K and Cr(K) be the crossing number of K. In this paper, we show that there exists a constant a>0 such that L(K) is bounded above…
Fractal Location and Anomalous Diffusion Dynamics for Oil Wells from the KY Geological Survey
Keith Andrew, Karla M. Andrew, Kevin A. Andrew
Utilizing data available from the Kentucky Geonet (KYGeonet.ky.gov) the fossil fuel mining locations created by the Kentucky Geological Survey geo-locating oil and gas wells are ma…
I-GALFA: The Inner-Galaxy ALFA Low-Latitude H I Survey
Bon-Chul Koo, Steven J. Gibson, Ji-hyun Kang +6
The I-GALFA survey is mapping all the HI in the inner Galactic disk visible to the Arecibo 305m telescope within 10 degrees of the Galactic plane (longitudes of 32 to 77 deg at b=0…
On Visibility and Blockers
Attila Pór, David R. Wood
This expository paper discusses some conjectures related to visibility and blockers for sets of points in the plane.
Nuclear Radii Calculations in Various Theoretical Approaches for Nucleus-Nucleus Interactions
C. Merino, I. S. Novikov, Yu. M. Shabelski
The information about sizes and nuclear density distributions in unstable (radioactive) nuclei is usually extracted from the data on interaction of radioactive nuclear beams with a…
Exotic relation modules and homotopy types for certain 1-relator groups
Jens Harlander, Jacqueline A Jensen
Using stably free non-free relation modules we construct an infinite collection of 2-dimensional homotopy types, each of Euler-characteristic one and with trefoil fundamental group…
