1605.06244 | in this work we study the equatorial causal geodesics of the taub - nut ( tn ) space - time in comparison with _ mass - less _ tn space - time . we emphasized both on the null circular geodesics and time - like circular geodesics . from the effective potential diagram of null and time - like geodesics , we differentiat... | 290 |
0806.1595 | one of the points at issue with closed - loop - type interferometers is beating in the aharonov - bohm ( ab ) oscillations . recent observations suggest the possibility that the beating results from the berry - phase pickup by the conducting electrons in materials with the strong spin - orbit interaction ( soi ) . in t... | 257 |
1106.2608 | we have evaluated a 20-in . photoelectric lens image intensifier tube ( pli ) to be mounted on the spherical focal surface of the ashra light collectors , where ashra stands for all - sky survey high resolution air - shower detector , an unconventional optical collector complex that images air showers produced by very ... | 196 |
1307.5232 | ultraviolet observations from low earth orbit ( leo ) have to deal with a foreground comprised of airglow and zodiacal light which depend on the look direction and on the date and time of the observation . we have used all - sky observations from the galex spacecraft to find that the airglow may be divided into a basel... | 120 |
1610.09093 | an edge in a @xmath0-connected graph @xmath1 is called _ @xmath0-contractible _ if the graph @xmath2 obtained from @xmath1 by contracting @xmath3 is @xmath0-connected . generalizing earlier results on @xmath4-contractible edges in spanning trees of @xmath4-connected graphs , we prove that ( except for the graphs @xmath... | 200 |
