Uncertainty transformation via Hopf bifurcation in fast-slow systems.

Proceedings. Mathematical, physical, and engineering sciences

Kuehn C.
PMID: 28484318
Proc Math Phys Eng Sci. 2017 Apr;473(2200):20160346. doi: 10.1098/rspa.2016.0346. Epub 2017 Apr 12.

Propagation of uncertainty in dynamical systems is a significant challenge. Here we focus on random multiscale ordinary differential equation models. In particular, we study Hopf bifurcation in the fast subsystem for random initial conditions. We show that a random...

Breastfeeding, lung volumes and alveolar size at school-age.

BMJ Open Respir Res. 2015 Jul 06;2(1):e000081. doi: 10.1136/bmjresp-2015-000081. eCollection 2015.

BACKGROUND: Previous studies found larger lung volumes at school-age in formerly breastfed children, with some studies suggesting an effect modification by maternal asthma. We wanted to explore this further in children who had undergone extensive lung function testing. The...

Syntheses of Strychnan- and Aspidospermatan-Type Alkaloids. 9.(1) The Enantioselective Generation of Tetracyclic ABCE Intermediates by a Tandem Condensation, [3,3]-Sigmatropic Rearrangement, and Cyclization Sequence.

J Org Chem. 1997 Nov 14;62(23):7950-7960. doi: 10.1021/jo970207j.

Reactions of substituted acroleins with the tryptophan-derived benzyl 2-(benzylamino)-3-[3-[2-[(methoxycarbonyl)methyl]indolyl]]propionate gave tetracyclic hexahydro-1H-pyrrolo[2,3-d] intermediates with stereoselective placement of substituents for cyclization to pentacyclic Strychnos alkaloids. The benzyl ester moiety was readily removed by formation of a corresponding nitrile and reduction,...

Syntheses of Strychnos and Aspidospermatan-Type Alkaloids. 8. Selective Total Syntheses of Mossambine and 14-epi-Mossambine by a Radical Cyclization Reaction(1).

The Journal of organic chemistry

Kuehne ME, Wang T, Seraphin D.
PMID: 11667746
J Org Chem. 1996 Nov 01;61(22):7873-7881. doi: 10.1021/jo961023s.

Mossambine (6) was obtained by a six-step reaction sequence from the indoloazepine ester 7. Radical cyclization of the tetracyclic vinyl iodide 12a provided a racemic pentacyclic ketone 16E, which could be converted to either enantiomer by condensation with (S...

How well are color components of samples of the Natural Color System estimated?.

J Opt Soc Am A Opt Image Sci Vis. 2011 Oct 01;28(10):1962-9. doi: 10.1364/JOSAA.28.001962.

The aim of this study was to determine how accurately color-normal subjects that have received basic information about, but do not have practical experience with, the Natural Color System (NCS) can estimate the Heringian components of a representative selection...

Dynamics of respiratory symptoms during infancy and associations with wheezing at school age.

ERJ open research

Children with frequent respiratory symptoms in infancy have an increased risk for later wheezing, but the association with symptom dynamics is unknown. We developed an observer-independent method to characterise symptom dynamics and tested their association with subsequent respiratory morbidity....

OBJECTIVES: Extracorporeal membrane oxygenation (ECMO) is a potentially lifesaving procedure in acute respiratory distress syndrome (ARDS) due to COVID-19. Previous studies have shown a high prevalence of clinically silent cerebral microbleeds in patients with COVID-19. Based on this fact,...
