Two-photon photovoltaic effect in gallium arsenide.

Optics letters

Ma J, Chiles J, Sharma YD, Krishna S, Fathpour S.
PMID: 26466255
Opt Lett. 2014 Sep 15;39(18):5297-300. doi: 10.1364/OL.39.005297.

The two-photon photovoltaic effect is demonstrated in gallium arsenide at 976 and 1550 nm wavelengths. A waveguide-photodiode biased in its fourth quadrant harvests electrical power from the optical energy lost to two-photon absorption. The experimental results are in good...

PMID: 26466277
Opt Lett. 2014 Sep 15;39(18):5379-82. doi: 10.1364/OL.39.005379.

A platform for high index-contrast integrated photonics based on tantalum pentoxide submicrometer waveguides on silicon substrates is introduced. The platform allows demonstration of microring resonators with loaded quality factor, Q, of 67,000 and waveguides with a propagation loss of...

Estimating hidden population size using Respondent-Driven Sampling data.

Electronic journal of statistics

Handcock MS, Gile KJ, Mar CM.
PMID: 26180577
Electron J Stat. 2014;8(1):1491-1521. doi: 10.1214/14-EJS923.

Respondent-Driven Sampling (RDS) is n approach to sampling design and inference in hard-to-reach human populations. It is often used in situations where the target population is rare and/or stigmatized in the larger population, so that it is prohibitively expensive...

A novel method for the transport and long-term storage of cultures and samples in an anaerobic atmosphere.

Letters in applied microbiology

Cragg BA, Bale SJ, Parkes RJ.
PMID: 29389029
Lett Appl Microbiol. 1992 Oct;15(4):125-128. doi: 10.1111/j.1472-765X.1992.tb00743.x.

Nylon-aluminium-polyethylene laminated, sealable bags provided a more economical and flexible method of transportation, incubation and storage than anaerobic jars. The bags were used with a special heat sealer and 'Anaerocult-A' sachets to remove oxygen. The environment inside the bags...

A surface code quantum computer in silicon.

Science advances

Hill CD, Peretz E, Hile SJ, House MG, Fuechsle M, Rogge S, Simmons MY, Hollenberg LC.
PMID: 26601310
Sci Adv. 2015 Oct 30;1(9):e1500707. doi: 10.1126/sciadv.1500707. eCollection 2015 Oct.

The exceptionally long quantum coherence times of phosphorus donor nuclear spin qubits in silicon, coupled with the proven scalability of silicon-based nano-electronics, make them attractive candidates for large-scale quantum computing. However, the high threshold of topological quantum error correction...

Total Synthesis of the Antitumor Macrolides, (+)-Brefeldin A and 4-Epi-Brefeldin A from d-Glucose: Use of the Padwa Anionic Allenylsulfone [3 + 2]-Cycloadditive Elimination To Construct Trans-Configured Chiral Cyclopentane Systems.

Org Lett. 2016 Sep 02;18(17):4254-7. doi: 10.1021/acs.orglett.6b02002. Epub 2016 Aug 19.

A new synthesis of (+)-brefeldin A is reported via Padwa allenylsulfone [3 + 2]-cycloadditive elimination. Cycloadduct 13 was initially elaborated into iodide 27, which, following treatment with Zn, gave aldehyde 28 whose C(9) stereocenter was epimerized. Further elaboration into...

Preliminary test of the LFA rapid evaluation of activity in lupus (LFA-REAL): an efficient outcome measure correlates with validated instruments.

OBJECTIVE: Current disease activity measures for systemic lupus erythematosus (SLE) are difficult to score or interpret and problematic for use in clinical practice. Lupus Foundation of America (LFA)-Rapid Evaluation of Activity in Lupus (REAL) is a pilot application composed...

Propane Clathrate Hydrate Formation Accelerated by Methanol.

The journal of physical chemistry letters

Amtawong J, Guo J, Hale JS, Sengupta S, Fleischer EB, Martin RW, Janda KC.

The role of methanol as both an inhibitor and a catalyst for the formation of clathrate hydrates (CHs) has been a topic of intense study. We report a new quantitative study of the kinetics of propane CH formation at...

Generation and detection of quantum turbulence in superfluid 3He-B.

Physical review letters

Fisher SN, Hale AJ, Guénault AM, Pickett GR.
PMID: 11177802
Phys Rev Lett. 2001 Jan 08;86(2):244-7. doi: 10.1103/PhysRevLett.86.244.

We describe the first direct observations of turbulence in superfluid 3He-B. The turbulence is generated by a vibrating-wire resonator driven at velocities exceeding the pair-breaking critical velocity. It is detected by the resulting decrease in the thermal damping on...
