This paper outlines the centralized design and production of ultra-high-vacuum sidearm laser-stabilization systems for AION Ultra-Cold Strontium Laboratories. Commissioning data on residual gas steady-state pressures in chambers, magnetic field quality, laser stabilization, loading rate 3D magneto-optical trap are presented. Streamlining stabilization enabled Collaboration to build equip parallel five state-of-the-art Laboratories within 24 months by leveraging key expertise collaboration....
One of the key challenges in reconstructive bone surgery is to provide living constructs that possess ability integrate surrounding host tissue. Bone graft substitutes and biomaterials have already been widely used heal critical-size defects due trauma, tumor resection tissue degeneration. In present study, gelatin-based cryogels seeded with human SAOS-2 osteoblasts followed by vitro culture cells. order overcome drawbacks associated static systems, including limited diffusion inhomogeneous...
Relativistic multiconfiguration Dirac-Hartree-Fock calculations with configuration interaction are carried out for the $^{1}S_{0}$ and $^{3}P_{0,1}^{o}$ states in neutral ytterbium by use of available grasp2018 package. From resultant atomic state functions ris4 program, we evaluate mass- field-shift parameters $^{1}S_{0}\ensuremath{-}\phantom{\rule{0.16em}{0ex}}^{3}P_{0}^{o}$ (clock) $^{1}S_{0}\ensuremath{-}\phantom{\rule{0.16em}{0ex}}^{3}P_{1}^{o}$ (intercombination) lines.

The relative separations between lines used evaluate $^{3}P_{1}$-level magnetic...
By use of the grasp2018 package we perform multiconfiguration Dirac-Hartree-Fock (MCDHF) calculations with configuration interaction (CI) for $^{1}S_{0}$ and $^{3}P_{0,1}^{o}$ levels in neutral cadmium mercury. supplying resultant atomic state functions to ris4 program, evaluate mass- field-shift parameters $^{1}S_{0}\ensuremath{-}\phantom{\rule{0.16em}{0ex}}^{3}P_{0}^{o}$ (clock) $^{1}S_{0}\ensuremath{-}{\phantom{\rule{0.16em}{0ex}}}^{3}{P}_{1}^{o}$ (intercombination) lines.

The leading experimental determinations of the fine-structure constant, $\alpha$, currently rely on atomic photon-recoil measurements from Ramsey-Bord\'e atom interferometry with large momentum transfer to provide an absolute mass measurement. We propose scheme for intermediate-scale differential interferometer measure neutral species a single-photon optical clock transition. calculate trajectories our that optimise recoil phase while nullifying undesired gravity gradient by considering...
We demonstrate a means of detecting weak optical transitions in cold atoms that undergo cyclic (preparation, probing, and detection) routines with improved sensitivity. The gain sensitivity is made by probing on alternate cycles repeated experimental sequence, leading to regular modulation the ground state atom population when at resonance frequency. atomic transition identified conducting fast Fourier transform via an algorithm or instrument. find enhancement detection compared more...
