Abstract This article presents Lock-V, a heterogeneous fault tolerance architecture that explores dual-core lockstep (DCLS) technique to mitigate single event upset (SEU) and common-mode failure (CMF) problems. The Lock-V was deployed in two versions, Lock-VA Lock-VM by applying design diversity processor architectures at the instruction set (ISA)-level. features an Arm Cortex-A9 with RISC-V RV...

Using a generalised version of Gershgorin's circle theorem, rigorous boundaries on the energies lowest states broad class line graphs above critical filling are derived for hardcore bosonic systems. Also lower boundary energy gap towards next is established. Additionally, it shown that corresponding eigenstates dominated by subspace spanned containing compactly localised pair and overlap as wel...

We consider a minimal model to investigate the quantum phases of hardcore, polarized dipolar atoms confined in multilayer optical lattices. The is variant extended Bose-Hubbard model, which incorporates intralayer repulsion and interlayer attraction between nearest-neighbour sites. study this emerging from competition attractive interaction hopping. Our results analytical cluster-Gutzwiller mea...

This article uses the example of a forgotten obscenity case from 1974 to show processes involved in production and distribution British hardcore pornographic 8-mm films, known trade as rollers. It also gives attention legal framework affecting pornography at this time, showing how Director Public Prosecutions, against backdrop increasing tabloid on transnational corruption Metropolitan police, ...

We introduce a unified framework to compute the solution space properties of broad class combinatorial optimization problems. These include finding one optimum solutions, counting number solutions given size, and enumeration sampling size. Using independent set problem as an example, we show how all these can be computed in approach generic tensor networks. demonstrate versatility this computat...
