Z=50 shell gap near Sn from intermediate-energy Coulomb excitations in even-mass Sn isotopes

C. Vaman, C. Andreoiu, D. Bazin +21

Rare isotope beams of neutron-deficient Sn nuclei from the fragmentation of Xe were employed in an intermediate-energy Coulomb excitation experiment yieldin…

Velocities measured in small scale solar magnetic elements

Øystein Langangen, Mats Carlsson, Luc Rouppe van der Voort +1

We have obtained high resolution spectrograms of small scale magnetic structures with the Swedish 1-m Solar Telescope. We present Doppler measurements at $0\farcs{2}$ spatial resol…

Universal Toda brackets of ring spectra

Steffen Sagave

We construct and examine the universal Toda bracket of a highly structured ring spectrum R. This invariant of R is a cohomology class in the Mac Lane cohomology of the graded ring…

The Algebraic Degree of Semidefinite Programming

Jiawang Nie, Kristian Ranestad, Bernd Sturmfels

Given a generic semidefinite program, specified by matrices with rational entries, each coordinate of its optimal solution is an algebraic number. We study the degree of the minima…

The algebra of harmonic functions for a matrix-valued transfer operator

Dorin Ervin Dutkay, Kjetil Roysland

We analyze matrix-valued transfer operators. We prove that the fixed points of transfer operators form a finite dimensional -algebra. For matrix weights satisfying a low-pass…

Using the cluster mass function from weak lensing to constrain neutrino masses

Jostein R. Kristiansen, Oystein Elgaroy, Hakon Dahle

We discuss the variation of cosmological upper bounds on , the sum of the neutrino masses, with the choice of data sets included in the analysis, pointing out a few oddities n…
