Critical Assessment of Photoionization Efficiency Measurements for Characterization of Soot-Precursor Species.

The journal of physical chemistry. A

Johansson KO, Zádor J, Elvati P, Campbell MF, Schrader PE, Richards-Henderson NK, Wilson KR, Violi A, Michelsen HA.
PMID: 28521094
J Phys Chem A. 2017 Jun 15;121(23):4475-4485. doi: 10.1021/acs.jpca.7b02992. Epub 2017 Jun 05.

We present a critical evaluation of photoionization efficiency (PIE) measurements coupled with aerosol mass spectrometry for the identification of condensed soot-precursor species extracted from a premixed atmospheric-pressure ethylene/oxygen/nitrogen flame. Definitive identification of isomers by any means is complicated by...

Health assessments for health governance-concepts and methodologies.

European journal of public health

Fehr R, Alexanderson K, Favaretti C, de Jong J, La Torre G, Lim TA, Martin-Olmedo P, Mekel OCL, Michelsen K, Rosenkötter N, Verschuuren M, de Waure C, Zeegers Paget D.
PMID: 28961876
Eur J Public Health. 2017 Aug 01;27(4):609-616. doi: 10.1093/eurpub/ckx062.

BACKGROUND: For better supporting the science-governance interface, the potential of health assessments appears underrated.AIMS: To identify what various types of health assessment have in common; how they differ; which assessment(s) to apply for which purpose; and what needs and...

Time-resolved laser-induced incandescence of soot: the influence of experimental factors and microphysical mechanisms.

Applied optics

Michelsen HA, Witze PO, Kayes D, Hochgreb S.
PMID: 14526849
Appl Opt. 2003 Sep 20;42(27):5577-90. doi: 10.1364/ao.42.005577.

We present a data set for testing models of time-resolved laser-induced incandescence of soot. Measurements were made in a laminar ethene diffusion flame over a wide range of laser fluences at 532 nm. The laser was seeded to provide...

Complications to optical measurements using a laser with an unstable resonator: a case study on laser-induced incandescence of soot.

Applied optics

Dansson MA, Boisselle M, Linne MA, Michelsen HA.
PMID: 18026549
Appl Opt. 2007 Nov 20;46(33):8095-103. doi: 10.1364/ao.46.008095.

Temporal behavior of pulses from a Q-switched Nd:YAG laser with an unstable resonator can vary significantly with radial position in the beam. Our laser provides pulses with position-dependent durations spanning 8-11.5 ns at 1064 nm and 7-10 ns at...

Particle formation from pulsed laser irradiation of soot aggregates studied with a scanning mobility particle sizer, a transmission electron microscope, and a scanning transmission x-ray microscope.

Applied optics

Michelsen HA, Tivanski AV, Gilles MK, van Poppel LH, Dansson MA, Buseck PR.
PMID: 17279144
Appl Opt. 2007 Feb 20;46(6):959-77. doi: 10.1364/ao.46.000959.

We investigated the physical and chemical changes induced in soot aggregates exposed to laser radiation using a scanning mobility particle sizer, a transmission electron microscope, and a scanning transmission x-ray microscope to perform near-edge x-ray absorption fine structure spectroscopy....

Modeling turbulence in underwater wireless optical communications based on Monte Carlo simulation.

Journal of the Optical Society of America. A, Optics, image science, and vision

Vali Z, Gholami A, Ghassemlooy Z, Michelson DG, Omoomi M, Noori H.
PMID: 29036128
J Opt Soc Am A Opt Image Sci Vis. 2017 Jul 01;34(7):1187-1193. doi: 10.1364/JOSAA.34.001187.

Turbulence affects the performance of underwater wireless optical communications (UWOC). Although multiple scattering and absorption have been previously investigated by means of physical simulation models, still a physical simulation model is needed for UWOC with turbulence. In this paper,...

MINdI: Mindfulness Instruction for New Interns.

MedEdPORTAL : the journal of teaching and learning resources

Cheston CC, Sox CM, Michelson CD, Fraiman YS.
PMID: 32754632
MedEdPORTAL. 2020 Jul 31;16:10933. doi: 10.15766/mep_2374-8265.10933.

INTRODUCTION: Trainee burnout has reached epidemic proportions and is increasing among physicians compared to non-health care professionals. Burnout is associated with depression and lower empathy, poor patient adherence to medical plans, and early physician retirement. Mindfulness is the quality...

Deficiency of PPARγ in Bone Marrow Stromal Cells Does not Prevent High-Fat Diet-Induced Bone Deterioration in Mice.

The Journal of nutrition

Cao JJ, Gregoire BR, Michelsen KG, Shi X.
PMID: 34113980
J Nutr. 2021 Sep 04;151(9):2697-2704. doi: 10.1093/jn/nxab173.

BACKGROUND: Bone marrow osteoblasts and adipocytes are derived from a common mesenchymal stem cell and have a reciprocal relationship. Peroxisome proliferator-activated receptor gamma (PPARγ), a regulator for adipocyte differentiation, may be a potential target for reducing obesity and increasing...
