User-based representation of time-resolved multimodal public transportation networks.

Royal Society open science

Alessandretti L, Karsai M, Gauvin L.
PMID: 27493773
R Soc Open Sci. 2016 Jul 13;3(7):160156. doi: 10.1098/rsos.160156. eCollection 2016 Jul.

Multimodal transportation systems, with several coexisting services like bus, tram and metro, can be represented as time-resolved multilayer networks where the different transportation modes connecting the same set of nodes are associated with distinct network layers. Their quantitative description...

Biomarker-based classification of bacterial and fungal whole-blood infections in a genome-wide expression study.

Frontiers in microbiology

Dix A, Hünniger K, Weber M, Guthke R, Kurzai O, Linde J.

Front Microbiol. 2015 Mar 11;6:171. doi: 10.3389/fmicb.2015.00171. eCollection 2015.

Sepsis is a clinical syndrome that can be caused by bacteria or fungi. Early knowledge on the nature of the causative agent is a prerequisite for targeted anti-microbial therapy. Besides currently used detection methods like blood culture and PCR-based...

Fiber-based distance sensing interferometry.

Applied optics

Thurner K, Quacquarelli FP, Braun PF, Dal Savio C, Karrai K.
PMID: 25967221
Appl Opt. 2015 Apr 01;54(10):3051-63. doi: 10.1364/AO.54.003051.

We present an interferometric displacement sensor based on a folded low-finesse Fabry-Perot cavity. The fiber-optic sensor uses a quadrature detection scheme based on the wavelength modulation of a DFB laser. This enables measuring position changes over a range of...

Kinetics of Social Contagion.

Physical review letters

Ruan Z, Iñiguez G, Karsai M, Kertész J.
PMID: 26636878
Phys Rev Lett. 2015 Nov 20;115(21):218702. doi: 10.1103/PhysRevLett.115.218702. Epub 2015 Nov 20.

Diffusion of information, behavioral patterns or innovations follows diverse pathways depending on a number of conditions, including the structure of the underlying social network, the sensitivity to peer pressure and the influence of media. Here we study analytically and...

Locomotion pattern and trunk musculoskeletal architecture among Urodela.

Acta zoologica (Stockholm, Sweden)

Omura A, Ejima KI, Honda K, Anzai W, Taguchi Y, Koyabu D, Endo H.
PMID: 25914411
Acta Zool. 2015 Apr;96(2):225-235. doi: 10.1111/azo.12070. Epub 2014 Feb 10.

We comparatively examined the trunk musculature and prezygapophyseal angle of mid-trunk vertebra in eight urodele species with different locomotive modes (aquatic

Acta crystallographica. Section E, Crystallographic communications

Alshawi J, Yousif M, Zangana KH, Vitorica Yrezabal IJ, Winpenny R, Al-Jeboori MJ.
PMID: 25844229
Acta Crystallogr E Crystallogr Commun. 2015 Feb 13;71:o165-6. doi: 10.1107/S2056989015002674. eCollection 2015 Mar 01.

The whole mol-ecule of the title compound, C24H32N4O4, is generated by inversion symmetry. The cyclo-hexane ring adopts a chair conformation and the conformation about the C=N bonds is E. The pyrrole rings have an anti confirmation with respect to...

High-Resolution Imaging of Polyethylene Glycol Coated Dendrimers via Combined Atomic Force and Scanning Tunneling Microscopy.

Journal of drug delivery

Riechers S, Zhong Q, Yin NN, Karsai A, da Rocha SR, Liu GY.
PMID: 25685559
J Drug Deliv. 2015;2015:535683. doi: 10.1155/2015/535683. Epub 2015 Jan 01.

Dendrimers have shown great promise as drug delivery vehicles in recent years because they can be synthesized with designed size and functionalities for optimal transportation, targeting, and biocompatibility. One of the most well-known termini used for biocompatibility is polyethylene...

The nonlinear Fano effect.

Nature

Kroner M, Govorov AO, Remi S, Biedermann B, Seidl S, Badolato A, Petroff PM, Zhang W, Barbour R, Gerardot BD, Warburton RJ, Karrai K.
PMID: 18202652
Nature. 2008 Jan 17;451(7176):311-4. doi: 10.1038/nature06506.

The Fano effect is ubiquitous in the spectroscopy of, for instance, atoms, bulk solids and semiconductor heterostructures. It arises when quantum interference takes place between two competing optical pathways, one connecting the energy ground state and an excited discrete...

Voltage control of the spin dynamics of an exciton in a semiconductor quantum dot.

Physical review letters

Smith JM, Dalgarno PA, Warburton RJ, Govorov AO, Karrai K, Gerardot BD, Petroff PM.

We report the observation of a spin-flip process in a quantum dot whereby a dark exciton with total angular momentum L = 2 becomes a bright exciton with L = 1. The spin-flip process is revealed in the decay...
