particular, grating MOTs of diverse species like Li, Sr, or even molecules offer paths toward making new sensors. Our motivation is making a cold-atom based vacuum standard (CAVS) that also doubles as a vacuum

; signal averaging can be used to optimize signal-to-noise ratios; a wide range of molecular masses is accessible; and the sample can be gas, liquid, or solid. Despite these advantages, the use of NMR

. The established uncertainty benchmark for absolute JNT is 12 ppm at the triple point of water (273.15 K), with more recent measurements achieving statistical uncertainties of 3 ppm. For temperatures in the range

folding of a protein biologic is critical for drug efficacy, misfolding may impact drug safety by eliciting unwanted immune and/or other off-target responses. High-resolution measurements of the structure(s

called the Fire Dynamics Simulator (FDS) . FDS is a block structured Cartesian LES code for low-speed flow which uses a high-order cutcell-immersed boundary method for complex geometry and is specifically
