Wc report on a study to dctcrminc the efllciency of various buffer gases in quenching the population trapping states of laser excited ytterbium ions. 'The ions were confined in an rf/dc hybrid trap, and their 2 S 1 / 2 H 2 P 3 / 2 transition was excited with 329 nm ]ascr light. Buflcr gsscs used include 11 2 , N2, C02, Ar, and llc at several diflcrcnt pressure rcgitncs. Wc have identified N 2 t...

We present a new seismic inversion method that uses deep learning (DL) features for the subsurface velocity model estimation. The DL feature is low-dimensional representation of high-dimensional data, which automatically generated by convolutional autoencoder (CAE) and preserved in latent space. contains key information input data. Therefore, instead directly comparing waveform differences betw...

This paper overviews the recent advances in flux-adjustable permanent magnet (PM) machines for traction applications. The PM benefit from synergies of high torque density and efficiency conventional as well controllable air-gap field wound-field machines, which are attractive applications requiring enhanced capabilities speed regulation uncontrolled voltage mitigation. In general, three solutio...

A new platform based on a hybrid optomechanical microcavity for coupling of electrically excited gigahertz phonons and exciton-polaritons provides coherent interface between microwave near-infrared photons.

This paper studies the parallel machine scheduling problem subject to machine and job deterioration in a batched delivery system. By the machine deterioration effect, we mean that each machine deteriorates over time, at a different rate. Moreover, job processing times are increasing functions of their starting times and follow a simple linear deterioration. The objective functions are minimizin...

In this paper, we describe ZZX_MT machine translation system for the NTCIR-9 Patent Machine Translation Task(PatentMT). We participated in the Chinese-English translation subtask and submit three results, which correspond to three different models or decoding algorithms respectively. Both of the first two are phrase-based SMT approaches integrating the BTG constraint into reordering models, and...

In this article, we describe the machine translation systems we used to create MorphoLogic’s submissions to the WMT09 shared Hungarian to English and English to Hungarian shared translation tasks. We used our rule based MetaMorpho system to generate our primary submission. In addition, we created a hybrid system where the Moses decoder is used to rank translations or assemble partial translatio...

By combining complementary optical techniques, photoluminescence and time-resolved excited state absorption, we achieve a comprehensive picture of the relaxation processes in the organic/inorganic hybrid system SP6/ZnO. We identify two long-lived excited states of the organic molecules of which only the lowest energy one, localized on the sexiphenyl backbone of the molecule, is found to efficie...
