Communication: The performance of non-iterative coupled cluster quadruples models.

The Journal of chemical physics

Eriksen JJ, Matthews DA, Jørgensen P, Gauss J.
PMID: 26233096
J Chem Phys. 2015 Jul 28;143(4):041101. doi: 10.1063/1.4927247.

We compare the numerical performance of various non-iterative coupled cluster (CC) quadruples models. The results collectively show how approaches that attempt to correct the CC singles and doubles energy for the combined effect of triple and quadruple excitations all...

Dynamic radiostereometric analysis for evaluation of hip joint pathomechanics.

Journal of experimental orthopaedics

Hansen L, de Raedt S, Jørgensen PB, Mygind-Klavsen B, Kaptein B, Stilling M.
PMID: 28585023
J Exp Orthop. 2017 Dec;4(1):20. doi: 10.1186/s40634-017-0096-2. Epub 2017 Jun 05.

BACKGROUND: Dynamic RSA (dRSA) enables non-invasive 3D motion-tracking of bones and may be used to evaluate in-vivo hip joint kinematics including hip pathomechanics such as femoroacetabular impingement (FAI) and the biomechanical effects of arthroscopic cheilectomy and -rim trimming (ACH)....

Linear-Scaling Coupled Cluster with Perturbative Triple Excitations: The Divide-Expand-Consolidate CCSD(T) Model.

Journal of chemical theory and computation

Eriksen JJ, Baudin P, Ettenhuber P, Kristensen K, Kjærgaard T, Jørgensen P.
PMID: 26575735
J Chem Theory Comput. 2015 Jul 14;11(7):2984-93. doi: 10.1021/acs.jctc.5b00086. Epub 2015 Jun 10.

We propose a reformulation of the traditional (T) triples correction to the coupled cluster singles and doubles (CCSD) energy in terms of local Hartree-Fock (HF) orbitals such that its structural form aligns with our recently developed linear-scaling divide-expand-consolidate (DEC)...

A view on coupled cluster perturbation theory using a bivariational Lagrangian formulation.

The Journal of chemical physics

Kristensen K, Eriksen JJ, Matthews DA, Olsen J, Jørgensen P.
PMID: 26874478
J Chem Phys. 2016 Feb 14;144(6):064103. doi: 10.1063/1.4941605.

We consider two distinct coupled cluster (CC) perturbation series that both expand the difference between the energies of the CCSD (CC with single and double excitations) and CCSDT (CC with single, double, and triple excitations) models in orders of...

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...

Microcosm-based analyses of Scots pine seedling growth, ectomycorrhizal fungal community structure and bacterial carbon utilization profiles in boreal forest humus and underlying illuvial mineral horizons.

FEMS microbiology ecology

Heinonsalo J, Jørgensen KS, Sen R.
PMID: 11377775
FEMS Microbiol Ecol. 2001 Jun;36(1):73-84. doi: 10.1111/j.1574-6941.2001.tb00827.x.

We report on the identity of indigenous mycorrhiza forming fungi and rhizosphere/mycorrhizosphere bacterial community carbon source utilization profiles of Scots pine (Pinus sylvestris L.) seedlings grown in boreal forest humus (O) or illuvial (B) mineral horizon containing microcosm growth...

A density matrix-based quasienergy formulation of the Kohn-Sham density functional response theory using perturbation- and time-dependent basis sets.

The Journal of chemical physics

Thorvaldsen AJ, Ruud K, Kristensen K, Jørgensen P, Coriani S.
PMID: 19063545
J Chem Phys. 2008 Dec 07;129(21):214108. doi: 10.1063/1.2996351.

A general method is presented for the calculation of molecular properties to arbitrary order at the Kohn-Sham density functional level of theory. The quasienergy and Lagrangian formalisms are combined to derive response functions and their residues by straightforward differentiation...

The Copenhagen Stroke Study experience.

Journal of stroke and cerebrovascular diseases : the official journal of National Stroke Association

Jørgensen HS.
PMID: 17894959
J Stroke Cerebrovasc Dis. 1996 Sep-Oct;6(1):5-16. doi: 10.1016/s1052-3057(96)80020-6.

The Copenhagen Stroke (COST) Study was a prospective, consecutive, community-based study of 1,197 patients with acute stroke who underwent acute stroke care and rehabilitation in a stroke unit setting. This article reviews the results of this study with respect...

Treatment of patients with first-episode psychosis: two-year outcome data from the Danish National Schizophrenia Project.

World psychiatry : official journal of the World Psychiatric Association (WPA)

PMID: 16946951
World Psychiatry. 2006 Jun;5(2):100-3.

First episode psychosis interventions have been in focus in the last two decades in an attempt to improve the course and outcome of schizophrenic disorders. The Danish National Schizophrenia Project began in 1997 its intake of patients, aged 16-35,...

The bering small vehicle asteroid mission concept.

Annals of the New York Academy of Sciences

Michelsen R, Andersen A, Haack H, Jørgensen JL, Betto M, Jørgensen PS.

The study of asteroids is traditionally performed by means of large Earth based telescopes, by means of which orbital elements and spectral properties are acquired. Space borne research, has so far been limited to a few occasional flybys and...
