Kantar MB, Sosa CC, Khoury CK, Castañeda-Álvarez NP, Achicanoy HA, Bernau V, Kane NC, Marek L, Seiler G, Rieseberg LH.
PMID: 26500675
Front Plant Sci. 2015 Oct 08;6:841. doi: 10.3389/fpls.2015.00841. eCollection 2015.

Crop wild relatives (CWR) are a rich source of genetic diversity for crop improvement. Combining ecogeographic and phylogenetic techniques can inform both conservation and breeding. Geographic occurrence, bioclimatic, and biophysical data were used to predict species distributions, range overlap...

Direct measurement of the biphoton Wigner function through two-photon interference.

Scientific reports

Douce T, Eckstein A, Walborn SP, Khoury AZ, Ducci S, Keller A, Coudreau T, Milman P.
PMID: 24346262
Sci Rep. 2013 Dec 18;3:3530. doi: 10.1038/srep03530.

The Hong-Ou-Mandel (HOM) experiment was a benchmark in quantum optics, evidencing the non-classical nature of photon pairs, later generalized to quantum systems with either bosonic or fermionic statistics. We show that a simple modification in the well-known and widely...

Reversible Gating of Plasmonic Coupling for Optical Signal Amplification.

ACS Appl Mater Interfaces. 2016 Jul 20;8(28):18157-64. doi: 10.1021/acsami.6b04623. Epub 2016 Jul 07.

Amplification of optical signals is useful for a wide variety of applications, ranging from data signal transmission to chemical sensing and biomedical diagnostics. One such application in chemical sensing is surface-enhanced Raman scattering (SERS), an important technique for increasing...

Mesh-wrapping for the treatment of fractured liver-A case report.

INTRODUCTION: Major liver trauma is a potentially fatal injury. Management of liver injuries has considerably changed over the past decades with a trend towards a multidisciplinary approach. Most liver injuries can be managed conservatively; however, some cases need operative...

Distributions, ex situ conservation priorities, and genetic resource potential of crop wild relatives of sweetpotato [Ipomoea batatas (L.) Lam., I. series Batatas].

Frontiers in plant science

Khoury CK, Heider B, Castañeda-Álvarez NP, Achicanoy HA, Sosa CC, Miller RE, Scotland RW, Wood JR, Rossel G, Eserman LA, Jarret RL, Yencho GC, Bernau V, Juarez H, Sotelo S, de Haan S, Struik PC.

Front Plant Sci. 2015 Apr 21;6:251. doi: 10.3389/fpls.2015.00251. eCollection 2015.

Crop wild relatives of sweetpotato [Ipomoea batatas (L.) Lam., I. series Batatas] have the potential to contribute to breeding objectives for this important root crop. Uncertainty in regard to species boundaries and their phylogenetic relationships, the limited availability of...

Adaptive defect and pattern detection in amplitude and phase structures via photorefractive four-wave mixing.

Applied optics

Nehmetallah G, Banerjee P, Khoury J.
PMID: 26560795
Appl Opt. 2015 Nov 10;54(32):9622-9. doi: 10.1364/AO.54.009622.

This work comprises the theoretical and numerical validations of experimental work on pattern and defect detection of periodic amplitude and phase structures using four-wave mixing in photorefractive materials. The four-wave mixing optical processor uses intensity filtering in the Fourier...

Quantum stability of chameleon field theories.

Physical review letters

Upadhye A, Hu W, Khoury J.
PMID: 23006073
Phys Rev Lett. 2012 Jul 27;109(4):041301. doi: 10.1103/PhysRevLett.109.041301. Epub 2012 Jul 23.

Chameleon scalar fields are dark-energy candidates which suppress fifth forces in high density regions of the Universe by becoming massive. We consider chameleon models as effective field theories and estimate quantum corrections to their potentials. Requiring that quantum corrections...

Acute appendicitis presenting as priapism in an 8 year old.

The Canadian journal of urology

Iocca AJ, Khoury AE.
PMID: 11305960
Can J Urol. 1998 Aug;5(3):597-598.

Priapism is uncommon in children. When it does occur the etiology is usually leukemia, sickle cell disease, or trauma.(1) We present a case of priapism in a child in whom the underlying etiology was acute appendicitis. To our knowledge,...

Observation of image transfer and phase conjugation in stimulated down-conversion.

Physical review letters

Ribeiro PH, Caetano DP, Almeida MP, Huguenin JA, dos Santos BC, Khoury AZ.

We observe experimentally the transfer of angular spectrum and image formation in the process of stimulated parametric down-conversion. Images and interference patterns can be transferred from either the pump or the auxiliary laser beams to the stimulated down-converted one....

Pulsed fluorescence measurements of trapped molecular ions with zero background detection.

Journal of the American Society for Mass Spectrometry
