DROID: discrete-time simulation for ring-oscillator-based Ising design by Abhimanyu Kumar, Ramprasath S., Chris H. Kim, Ulya R. Karpuzcu, Sachin S. Sapatnekar

“…On a realistic-size all-to-all coupled ring oscillator array, DROID is nearly four orders of magnitude faster than a traditional HSPICE simulation and two orders of magnitude faster than a commercial fast SPICE solver in predicting the evolution of a coupled oscillator system and is demonstrated to attain a similar distribution of solutions as the hardware.…”

Long-range CCΦ gates via radio-frequency-induced Förster resonances by I. N. Ashkarin, S. Lepoutre, P. Pillet, I. I. Beterov, I. I. Ryabtsev, P. Cheinet

“…Here we present a CCΦ quantum phase gate protocol based on radio-frequency-induced Förster resonant interactions in the array of highly excited ^{87}Rb atoms. The extreme controllability of interactions provided by rf field application enables high-fidelity and robust gate performance for a wide range of parameters of the atomic system, as well as it significantly facilitates the experimental implementation of the gate protocol. …”

Orphan love in the age of capital by Hans Skott-Myhre, Kathleen S.G. Skott-Myhre, Scott Kouri, Jeff Smith

“…This paper will argue that residential care is a field of encounter saturated with a complex and intricate array of affects. If the rule of capitalism is designed to abstract lived experience, then any affirmation of the corporeal experience of encounter as lived experience might well constitute an alternative affirmation of life and hence a revolutionary set of possibilities. …”

Cost-efficient assignment panel for ducks. Setup of a cost-efficient assignment panel for duck populations.  by Chapuis, Hervé, Brard-Fudulea, Sophie, Hazard, Azélie, Vignal, Alain, Demars, Julie, Rouger, Romuald, Teissier, Marc, Gilbert, Hélène

“…SNP were selected on the available 600K array in ducks. This SNP array is made of two libraries (one for the Muscovy duck, the other for the common duck which encompasses the Pekin duck), the intersection of which, after a preliminary elimination on the primer length, contained only 399 SNP that were considered a starting point to obtain a final list. …”
