Det finnes alternative samfunnsformer hvor mennesker ikke nŸdvendigvis må forvalte livet sitt etter arbeidsmarkedets krav om lŸnn og profitt.
I dagens kapitalisme er det vanlig at arbeidskraft og produksjonsmidler eies av noen få, og at Ÿkonomiske beslutninger ofte tar utgangspunkt i profittmotivet og eksisterende hierarki.
I slike alternative systemer kan mennesker i stŸrre grad selv bestemme over egen arbeidskraft og leve uten å være avhengige av penger som hovednŸdvendighet fo…

Engineering and harnessing long-range interactions for atomic quantum simulators
Interactions between quantum particles, such as electrons, are the source of important effects, ranging from superconductivity, to the formation of molecular bonds, or the stability of elementary compounds at high-energies. In this article, we illustrate how advances in the cold-atom community to further engineer such long-range interactions have stimulated the simulation of new regimes of these fundamental many-body problems. The goal is two-fold: first, to provide a comprehensive review of th…

Densetsu no Stafy: spin spin spin
When renewing my subscription to Nintendo Online it was only marginally more to upgrade to the expansion pass, which has given my sons access to the Mario Kart 8 Deluxe DLC, will provide me with upgrades for Tears of the Kingdom on the Switch 2, and also gives me access to the N64, GBA and MD libraries. Tempted as I was to immediately start playing through Streets of Rage 2 again, I instead had a look for anything new and interesting.

Horizontal Descent, Immersions, Unramified Morphisms, Submersions, Étale Morphisms and the Relative Cotangent Sequence in Tangent Categories
In this paper we provide a deep and systematic study of the classes of what it means to be an immersion, a submersion, a local diffeomorphism, and unramified in a tangent category. We also give a systematic study of the ways in which these classes of morphisms interact, the properties they have, and give very explicit and concrete characterizations of how each class of maps appear in algebraic geometry, in differential geometry, in the theory of semirings, and in the theory of Cartesian differe…

The Epoch of Giant Planet Migration Planet Search Program. III. The Occurrence Rate of Young Giant Planets Inside the Water Ice Line
We present statistical results from the Epoch of Giant Planet Migration RV planet search program. This survey was designed to measure the occurrence rate of giant planets interior to the water ice line of young Sun-like stars, compare this to the prevalence of giant planets at older ages, and provide constraints on the timescale and dominant inward migration mechanism of giant planets. Our final sample amounts to 85 single young (20-200 Myr) G and K dwarfs which we target across a 4-year time b…

Bango: Subscription providers turn to bundling as direct acquisition marketing falters
Marketers of subscription services including those themed around streaming video and music are cutting back on once reliable direct acquisition strategies, including display and social media advert | A new Bango study concludes that subscription service providers are cutting back on once reliable direct acquisition strategies, including display and social media advertising, for customer growth and are turning to indirect marketing mechanisms like bundling.

Interstellar Chemistry of CN Radicals on Ices: The formation of CH3CN and CH3NC and potential connection to acetamide
Context. Among the most significant chemical functional groups of interstellar molecules are the class of nitriles, which are proposed as key prebiotic molecules due to their chemical connection to the peptide bond after hydrolysis. CN radicals, the simplest representative of this group, have been shown to exhibit strong interactions with interstellar water ices, potentially impacting their reactivity with other radicals nearby. Aims. This study explores (a) whether CN and CH3 radicals can read…

On the exact solutions of a two-dimensional hydrogen atom in a constant magnetic field
We analyse the exact solutions to some quantum-mechanical models derived recently by means of a generalization of the Frobenius method. In particular, we carry out an interpretation of the polynomial solutions obtained for the two-dimensional hydrogen atom in a constant magnetic field by comparing the exact solutions with numerical results provided by the Rayleigh-Ritz method.
