Optical resonance imaging: An optical analog to MRI with sub-diffraction-limited capabilities.

ACS photonics

Allodi MA, Dahlberg PD, Mazuski RJ, Davis HC, Otto JP, Engel GS.
PMID: 28451625
ACS Photonics. 2016 Dec 21;3(12):2445-2452. doi: 10.1021/acsphotonics.6b00694. Epub 2016 Nov 08.

We propose here optical resonance imaging (ORI), a direct optical analog to magnetic resonance imaging (MRI). The proposed pulse sequence for ORI maps space to time and recovers an image from a heterodyne-detected third-order nonlinear photon echo measurement. As...

Given the prevalence of social media websites, one challenge facing computer vision researchers is to devise methods to search for persons of interest among the billions of shared photos on these websites. Despite significant progress in face recognition, searching...

Synthesis, Characterization, and Reactivity of a High-Spin Iron(II) Hydrido Complex Supported by a PNP Pincer Ligand and Its Application as a Homogenous Catalyst for the Hydrogenation of Alkenes.

This study focused on the synthesis and characterization of a range of low-valent, high-spin iron(II) complexes supported by a carbazole-based PNP pincer-type ligand. The addition of the lithiated ligand (PNP)Li to FeCl

Positive Contrast MRI Techniques for Visualization of Iron-Loaded Hernia Mesh Implants in Patients.

PloS one

Ciritsis A, Truhn D, Hansen NL, Otto J, Kuhl CK, Kraemer NA.

PLoS One. 2016 May 18;11(5):e0155717. doi: 10.1371/journal.pone.0155717. eCollection 2016.

OBJECT: In MRI, implants and devices can be delineated via susceptibility artefacts. To discriminate susceptibility voids from proton-free structures, different positive contrast techniques were implemented. The purpose of this study was to evaluate a pulse sequence-based positive contrast technique...

Manipulating coherence resonance in a quantum dot semiconductor laser via electrical pumping.

Optics express

Otto C, Lingnau B, Schöll E, Lüdge K.
PMID: 24921523
Opt Express. 2014 Jun 02;22(11):13288-307. doi: 10.1364/OE.22.013288.

Excitability and coherence resonance are studied in a semiconductor quantum dot laser under short optical self-feedback. For low pump levels, these are observed close to a homoclinic bifurcation, which is in correspondence with earlier observations in quantum well lasers....

Thermal reaction of white phosphorus with [(triphos)RhH(3)] (1) in THF affords [(triphos)Rh(eta(1):eta(2)-P(4)H)] (2), triphos=MeC(CH(2)PPh(2))(3). Similar complexes [(triphos)Rh(eta(1):eta(2)-P(4)R)] (R=Me (7), Et (8), Ph (9)) also form at lower temperature by the reaction of P(4) and [(triphos)Rh(R)(eta(2)-C(2)H(4))] with elimination of ethene....
