Parameter space boundaries for unidentifiable compartmental models.

Mathematical biosciences

Vajda S, Distefano JJ, Godfrey KR, Fagarasan J.
PMID: 2520205
Math Biosci. 1989 Nov;97(1):27-60. doi: 10.1016/0025-5564(89)90042-4.

Methods for dealing with unidentifiable compartmental models are first reviewed, emphasizing the parameter interval analysis and exhaustive modeling approaches. More general methods are presented for generating the set of all nonnegative parameter solutions that localize the parameters within bounded...

"Crystallographic" holes: new insights for a beneficial structural feature for photocatalytic applications.

Nanoscale

Vajda K, Kása Z, Dombi A, Németh Z, Kovács G, Danciu V, Radu T, Ghica C, Baia L, Hernádi K, Pap Z.
PMID: 25757557
Nanoscale. 2015 Mar 19;7(13):5776-86. doi: 10.1039/c4nr07157c.

One of the most fundamental aspects of the heterogeneous catalysis field is the manipulation of the catalysts' activity. In photocatalysis this is carried out by maximizing the right crystal plane of a semiconductor oxide. Until now, most of the...

1.024 Tb/s wavelength conversion in a silicon waveguide with reverse-biased p-i-n junction.

Optics express

Sackey I, Gajda A, Peczek A, Liebig E, Zimmermann L, Petermann K, Schubert C.
PMID: 29041528
Opt Express. 2017 Sep 04;25(18):21229-21240. doi: 10.1364/OE.25.021229.

We experimentally show an all-optical wavelength conversion of 8 × 32-GBd single-polarization 16QAM signals using a silicon nano-rib waveguide. The application of reverse biasing of the p-i-n junction of the waveguide allows a conversion efficiency of -8.5 dB with...

Accurate on-line mass flow measurements in supercritical fluid chromatography.

Journal of chromatography. A

Tarafder A, Vajda P, Guiochon G.
PMID: 24210558
J Chromatogr A. 2013 Dec 13;1320:130-7. doi: 10.1016/j.chroma.2013.10.041. Epub 2013 Oct 22.

This work demonstrates the possible advantages and the challenges of accurate on-line measurements of the CO2 mass flow rate during supercritical fluid chromatography (SFC) operations. Only the mass flow rate is constant along the column in SFC. The volume...

Synthesis of a sucrose dimer with enone tether; a study on its functionalization.

Beilstein journal of organic chemistry

Pakulski Z, Gajda N, Jawiczuk M, Frelek J, Cmoch P, Jarosz S.
PMID: 24991275
Beilstein J Org Chem. 2014 May 28;10:1246-54. doi: 10.3762/bjoc.10.124. eCollection 2014.

The reaction of appropriately functionalized sucrose phosphonate with sucrose aldehyde afforded a dimer composed of two sucrose units connected via their C6-positions ('the glucose ends'). The carbonyl group in this product (enone) was stereoselectively reduced with zinc borohydride and...

A Subspace Semi-Definite programming-based Underestimation (SSDU) method for stochastic global optimization in protein docking.

Proceedings of the ... IEEE Conference on Decision & Control. IEEE Conference on Decision & Control

Nan F, Moghadasi M, Vakili P, Vajda S, Kozakov D, Ch Paschalidis I.
PMID: 25914440
Proc IEEE Conf Decis Control. 2014 Dec;2014:4623-4628. doi: 10.1109/CDC.2014.7040111.

We propose a new stochastic global optimization method targeting protein docking problems. The method is based on finding a general convex polynomial underestimator to the binding energy function in a permissive subspace that possesses a funnel-like structure. We use...

Pronounced Size Dependence in Structure and Morphology of Gas-Phase Produced, Partially Oxidized Cobalt Nanoparticles under Catalytic Reaction Conditions.

ACS nano

Bartling S, Yin C, Barke I, Oldenburg K, Hartmann H, von Oeynhausen V, Pohl MM, Houben K, Tyo EC, Seifert S, Lievens P, Meiwes-Broer KH, Vajda S.
PMID: 26027910
ACS Nano. 2015 Jun 23;9(6):5984-98. doi: 10.1021/acsnano.5b00791. Epub 2015 Jun 04.

It is generally accepted that optimal particle sizes are key for efficient nanocatalysis. Much less attention is paid to the role of morphology and atomic arrangement during catalytic reactions. Here, we unravel the structural, stoichiometric, and morphological evolution of...

PMID: 12543966
Science. 2003 Jan 24;299(5606):536-9. doi: 10.1126/science.1078517.

Femtosecond high-resolution pump-probe experiments have been used together with theoretical ab initio quantum calculations and wave packet dynamics simulations to decode an optimal femtosecond pulse that is generated from adaptive learning algorithms. This pulse is designed to maximize the...

The effect of sucrose and trehalose on viability of one- and two-cell rabbit embryos.
