Yikai Li, Jiayuan Mao, Xiuming Zhang, William T. Freeman, Joshua B. Tenenbaum, Noah Snavely, Jiajun Wu
2020 arXiv   pre-print
Unlike prior work on image-based program synthesis, which assumes the image contains a single visible 2D plane, we present Box Program Induction (BPI), which infers a program-like scene representation  ...  Our model assumes a box prior, i.e., that the image captures either an inner view or an outer view of a box in 3D.  ...  B Box Program Induction for Outer Views of Boxes In this section, we present the box program induction for outer views of boxes.  ...

UCSB final report for the CSQ program: Review of decoherence and materials physics for superconducting qubits [article]

John M. Martinis, A. Megrant
2014 arXiv   pre-print
With improved design, the performance of integrated circuit transmons using the Xmon design are now close to world record performance: these devices have the advantage of retaining coherence when scaled  ...  However, when comparing 3D transmons used as multi-qubit devices, the times are comparable or even a bit lower.  ...  It is interesting to speculate why 3D performance degrades upon scaling to multi-qubit systems, while not for Xmons.  ...

2005 Journal of magnetic resonance (San Diego, Calif. 1997 : Print)  
Additional general advantages of the FDM program for generating highresolution 2D slices in any dimension from a 4D spectrum are emphasized.  ...  Using an oligosaccharide derivatized with 13 C-labeled acetyl isotags, a four-dimensional constant-time pulse sequence was tailored for conjoint use with the FDM.  ...  The FDM essentially utilizes the relationships between all the points in all free-induction decays, as it deals intrinsically with the data as complex multi-dimensional sinusoids, rather than being restricted  ...
