Acousto-optic superlattice modulation in fiber Bragg gratings.

Journal of the Optical Society of America. A, Optics, image science, and vision

Russell PS, Liu WF.
PMID: 10935870
J Opt Soc Am A Opt Image Sci Vis. 2000 Aug;17(8):1421-9. doi: 10.1364/josaa.17.001421.

The superposition of a long-period grating and a fiber Bragg grating, which we call an optical superlattice, causes high-efficiency narrow-band reflections to be induced on either side of the Bragg wavelength. This effect was recently observed experimentally in a...

Isospin diffusion and the nuclear symmetry energy in heavy ion reactions.

Physical review letters

Tsang MB, Liu TX, Shi L, Danielewicz P, Gelbke CK, Liu XD, Lynch WG, Tan WP, Verde G, Wagner A, Xu HS, Friedman WA, Beaulieu L, Davin B, de Souza RT, Larochelle Y, Lefort T, Yanez R, Viola VE, Charity RJ, Sobotka LG.
PMID: 14995234
Phys Rev Lett. 2004 Feb 13;92(6):062701. doi: 10.1103/PhysRevLett.92.062701. Epub 2004 Feb 10.

Using symmetric 112Sn+112Sn, 124Sn+124Sn collisions as references, we probe isospin diffusion in peripheral asymmetric 112Sn+124Sn, 124Sn+112Sn systems at an incident energy of E/A=50 MeV. Isoscaling analyses imply that the quasiprojectile and quasitarget in these collisions do not achieve isospin...

Boron-mediated aldol reaction of carboxylic esters: complementary anti- and syn-selective asymmetric aldol reactions.

The Journal of organic chemistry

Inoue T, Liu JF, Buske DC, Abiko A.
PMID: 12126413
J Org Chem. 2002 Jul 26;67(15):5250-6. doi: 10.1021/jo0257896.

The boron-mediated aldol reaction of carboxylic esters is described in detail. Contrary to the general belief that carboxylic esters are inert under the condition of the boron enolate formation, propionate esters are enolized with certain combinations of a boron...

Total Synthesis of (+/-)-Cylindricines A and B.

The Journal of organic chemistry

Liu JF, Heathcock CH.
PMID: 11674746
J Org Chem. 1999 Oct 29;64(22):8263-8266. doi: 10.1021/jo991020q.

Cylindricine A (1) and cylindricine B (2) have been synthesized in 11 steps and 19% overall yield. The key reaction involves the addition of an organocopper species to a bicyclic vinylogous amide, which provides complete stereocontrol over the installation...

Identification of A Protein Interacting with Type 2 Methionine Aminopeptidase by Yeast Two-hybrid System.

Applications of the direct Trefftz boundary element method to the free-vibration problem of a membrane.

The Journal of the Acoustical Society of America

Chang JR, Liu RF, Yeih W, Kuo SR.
PMID: 12186033
J Acoust Soc Am. 2002 Aug;112(2):518-27. doi: 10.1121/1.1494992.

In this paper, the direct Trefftz method is applied to solve the free-vibration problem of a membrane. In the direct Trefftz method, there exists no spurious eigenvalue. However, an ill-posed nature of numerical instability encountered in the direct Trefftz...

Quasi-spin-wave quantum memories with a dynamical symmetry.

Physical review letters

Sun CP, Li Y, Liu XF.
PMID: 14611556
Phys Rev Lett. 2003 Oct 03;91(14):147903. doi: 10.1103/PhysRevLett.91.147903. Epub 2003 Oct 02.

For the two-mode exciton system formed by the quasi-spin-wave collective excitation of many Lambda atoms fixed at the lattice sites of a crystal, we discover a dynamical symmetry depicted by the semidirect product algebra SU2( multiply sign in circle)...

A N-heterocyclic carbene derived highly regioselective ambident C-C-S and C-C-N 1,3-dipolar system.
