Computational Study of the Clustering of a Cyclohexene Autoxidation Product C6H8O7 with Itself and Sulfuric Acid.

The journal of physical chemistry. A

Elm J, Myllys N, Hyttinen N, Kurtén T.
PMID: 26154271
J Phys Chem A. 2015 Jul 30;119(30):8414-21. doi: 10.1021/acs.jpca.5b04040. Epub 2015 Jul 21.

We investigate the molecular interactions between sulfuric acid and a recently reported C6H8O7 ketodiperoxy acid formed through autoxidation from cyclohexene and ozone. Structurally similar but larger ELVOC (extremely low volatility organic compound) products formed from autoxidation of monoterpenes are...

Computational Study of Hydrogen Shifts and Ring-Opening Mechanisms in α-Pinene Ozonolysis Products.

The journal of physical chemistry. A

Kurtén T, Rissanen MP, Mackeprang K, Thornton JA, Hyttinen N, Jørgensen S, Ehn M, Kjaergaard HG.
PMID: 26529548
J Phys Chem A. 2015 Nov 19;119(46):11366-75. doi: 10.1021/acs.jpca.5b08948. Epub 2015 Nov 10.

Autoxidation by sequential peroxy radical hydrogen shifts (H-shifts) and O2 additions has recently emerged as a promising mechanism for the rapid formation of highly oxidized, low-volatility organic compounds in the atmosphere. A key prerequisite for autoxidation is that the...

A head cap made of fabric for measuring EOG and facial EMG signals is presented. Reusable and easy to use electrodes, embroidered of silver coated thread, are integrated into the cap. A two-way wireless data transmission link operating at...

Network-Wide Adaptive Burst Detection Depicts Neuronal Activity with Improved Accuracy.

Frontiers in computational neuroscience

Välkki IA, Lenk K, Mikkonen JE, Kapucu FE, Hyttinen JAK.
PMID: 28620291
Front Comput Neurosci. 2017 May 31;11:40. doi: 10.3389/fncom.2017.00040. eCollection 2017.

Neuronal networks are often characterized by their spiking and bursting statistics. Previously, we introduced an adaptive burst analysis method which enhances the analysis power for neuronal networks with highly varying firing dynamics. The adaptation is based on single channels...

Causal Discovery from Subsampled Time Series Data by Constraint Optimization.

JMLR workshop and conference proceedings

Hyttinen A, Plis S, Järvisalo M, Eberhardt F, Danks D.
PMID: 28203316
JMLR Workshop Conf Proc. 2016 Aug;52:216-227.

This paper focuses on causal structure estimation from time series data in which measurements are obtained at a coarser timescale than the causal timescale of the underlying system. Previous work has shown that such subsampling can lead to significant...

Strong Even/Odd Pattern in the Computed Gas-Phase Stability of Dicarboxylic Acid Dimers: Implications for Condensation Thermodynamics.

The journal of physical chemistry. A

Elm J, Hyttinen N, Lin JJ, Kurtén T, Prisle NL.
PMID: 31610657
J Phys Chem A. 2019 Nov 07;123(44):9594-9599. doi: 10.1021/acs.jpca.9b08020. Epub 2019 Oct 28.

The physical properties of small straight-chain dicarboxylic acids are well known to exhibit even/odd alternations with respect to the carbon chain length. For example, odd numbered diacids have lower melting points and higher saturation vapor pressures than adjacent even...

Computational Comparison of Different Reagent Ions in the Chemical Ionization of Oxidized Multifunctional Compounds.

The journal of physical chemistry. A

Hyttinen N, Otkjær RV, Iyer S, Kjaergaard HG, Rissanen MP, Wennberg PO, Kurtén T.
PMID: 29200296
J Phys Chem A. 2018 Jan 11;122(1):269-279. doi: 10.1021/acs.jpca.7b10015. Epub 2017 Dec 22.

High pressure anion chemical ionization is commonly used for the detection of neutral molecules in the gas phase. The detection efficiency in these measurements depends on how strongly the reagent ion binds to the neutral target molecule. We have...

Predicting Indoor Concentrations of Black Carbon in Residential Environments.

Atmospheric environment (Oxford, England : 1994)

Isiugo K, Jandarov R, Cox J, Chillrud S, Grinshpun SA, Hyttinen M, Yermakov M, Wang J, Ross J, Reponen T.
PMID: 31598090
Atmos Environ (1994). 2019 Mar 15;201:223-230. doi: 10.1016/j.atmosenv.2018.12.053. Epub 2019 Jan 09.

Black carbon (BC) is a descriptive term that refers to light-absorbing particulate matter (PM) produced by incomplete combustion and is often used as a surrogate for traffic-related air pollution. Exposure to BC has been linked to adverse health effects....
