BACKGROUND: Phenotyping technologies are expected to provide predictive power for a range of applications in plant and crop sciences. Here, we use the disease pressure of Beet Cyst Nematodes (BCN) on sugar beet as an illustrative example to test...

Implementation of density functional embedding theory within the projector-augmented-wave method and applications to semiconductor defect states.

The Journal of chemical physics

Yu K, Libisch F, Carter EA.
PMID: 26373999
J Chem Phys. 2015 Sep 14;143(10):102806. doi: 10.1063/1.4922260.

We report a new implementation of the density functional embedding theory (DFET) in the VASP code, using the projector-augmented-wave (PAW) formalism. Newly developed algorithms allow us to efficiently perform optimized effective potential optimizations within PAW. The new algorithm generates...

Size-extensivity-corrected multireference configuration interaction schemes to accurately predict bond dissociation energies of oxygenated hydrocarbons.

The Journal of chemical physics

Oyeyemi VB, Krisiloff DB, Keith JA, Libisch F, Pavone M, Carter EA.
PMID: 25669533
J Chem Phys. 2014 Jan 28;140(4):044317. doi: 10.1063/1.4862159.

Oxygenated hydrocarbons play important roles in combustion science as renewable fuels and additives, but many details about their combustion chemistry remain poorly understood. Although many methods exist for computing accurate electronic energies of molecules at equilibrium geometries, a consistent...

Telecom technology based continuous wave terahertz photomixing system with 105 decibel signal-to-noise ratio and 3.5 terahertz bandwidth.

PMID: 24321958
Opt Lett. 2013 Oct 15;38(20):4197-9. doi: 10.1364/OL.38.004197.

A modified photoconductive receiver significantly improves the performance of photomixing-based continuous wave (cw) THz systems driven at the optical telecommunication wavelength of 1.5 μm. The achieved signal-to-noise ratio of 105 dB at 100 GHz and 70 dB at 1...

[The City and Health--an analysis of recent (socio-) historical literature].

Zentralblatt fur Hygiene und Umweltmedizin = International journal of hygiene and environmental medicine

Labisch A.
PMID: 8579704
Zentralbl Hyg Umweltmed. 1995 Apr;197(1):111-33.

"The City and Health" - this title joints two all-encompassing words. The city is the birthplace of modern civilization. Today, we are confronted with huge urban agglomarations--beyond our grasp and nearly out of control. Are we dealing with transitory...

Cryptosporidium antibodies in manitoba cattle: a pilot study using an indirect fluorescent antibody procedure.

The Canadian veterinary journal = La revue veterinaire canadienne

Mann ED, Sekla LH, Eibisch G.
PMID: 17422744
Can Vet J. 1987 Mar;28(3):126-8.

An indirect fluorescent antibody test, using feces-derived oocysts as antigen, was used to detect antibodies to Cryptosporidium spp. in bovine sera in Manitoba. Antibodies were detected in 29 of 50 (58%) sera collected from animals of various ages on...

Tunable Fano resonances in transport through microwave billiards.

Physical review. E, Statistical, nonlinear, and soft matter physics

Rotter S, Libisch F, Burgdörfer J, Kuhl U, Stöckmann HJ.

We present a tunable microwave scattering device that allows the controlled variation of Fano line shape parameters in transmission through quantum billiards. Transport in this device is nearly fully coherent. By comparison with quantum calculations, employing the modular recursive...

Influence of carrier lifetimes on the dynamical behavior of quantum-dot lasers subject to optical feedback.

We examine changes in the dynamics of a semiconductor quantum-dot (QD) laser subject to optical feedback that correlate to changes in the QD laser band structure. By employing a microscopic model for the carrier-carrier scattering processes between the QDs...

Opt Express. 2014 Aug 11;22(16):19411-22. doi: 10.1364/OE.22.019411.

We investigate the influence of Beryllium (Be) doping on the performance of photoconductive THz detectors based on molecular beam epitaxy (MBE) of low temperature (LT) grown In(0.53)Ga(0.47)As/In(0.52)Al(0.48)As multilayer heterostructures (MLHS). We show how the optical excitation power affects carrier...
