Leaving the Banquet
The offerings in this, my last issue as Editor of Addiction Science & Clinical Practice, reinforce my feeling of stepping away from a banquet that has many rich courses still to come. In this final issue produced by NIDA: • Drs. Manoranjan D’Souza and Athina Markou review what researchers have discovered about how nicotine affects brain function to produce dependence, and examine the prospects ...
متن کاملSpiral Meandering
The complex, so called meandering, dynamics of spiral waves in excitable media is examined from the point of view of bifurcation theory. A computational bifurcation analysis is made of spiral dynamics. It is shown that spiral meandering is organized in parameter space around a codimension-two point where a Hopf bifurcation from rotating waves interacts with symmetries on the plane. A simple mod...
متن کاملThe Study of Meandering Phenomenon on the Basis of Stream Power
On the basis of stream power, the phenomena including regime channel establishment and river meandering can be studied. So, previous researchers have suggested and developed the stream power theory and believed that stream power minimization affects these phenomena. In this paper, the stream power theory and a criterion for meandering river modeling will be studied. Then the conclusion of case ...
متن کاملSaturn’s Northern Hemisphere Ribbon: Simulations and Comparison with the Meandering Gulf Stream
Voyager observations of Saturn in 1980–81 discovered a wavy feature engirdling the planet at 478N planetographic latitude. Its latitude coincides with that of an eastward jet stream, which is the second fastest on Saturn after the equatorial jet. The 478N jet’s wavy morphology is unique among the known atmospheric jets on the gas giant planets. Since theVoyagers, it has been seen in every high-...
متن کاملInterdisciplinary Meandering in Science
I was a graduate student in mathematics at Princeton immediately following World War II, 1945–1947. In those days, with veterans of the war inundating universities, there was no option but to earn a Ph.D. within two years. My thesis research was in functional analysis, an area of abstract mathematics. My mentor was Professor S. Bochner, a distinguished contributor to harmonic analysis. My class...
