Parallel Implementation of Multireference Coupled-Cluster Theories Based on the Reference-Level Parallelism.

Journal of chemical theory and computation

Brabec J, Pittner J, van Dam HJ, Aprà E, Kowalski K.
PMID: 26596599
J Chem Theory Comput. 2012 Feb 14;8(2):487-97. doi: 10.1021/ct200809m. Epub 2012 Feb 01.

A novel algorithm for implementing a general type of multireference coupled-cluster (MRCC) theory based on the Jeziorski-Monkhorst exponential ansatz [Jeziorski, B.; Monkhorst, H. J. Phys. Rev. A1981, 24, 1668] is introduced. The proposed algorithm utilizes processor groups to calculate...

The impact of a formal complaint on Dutch dentists' professional practice: a survey study.

BMC oral health

Bruers JJ, van Dam BA, Gorter RC, Eijkman MA.
PMID: 27680549
BMC Oral Health. 2016 Sep 29;16(1):104. doi: 10.1186/s12903-016-0295-8.

BACKGROUND: A complaint from a patient can have a serious impact on the well-being of dentists. Little is known, however, about the nature and the extent of this impact.METHODS: Therefore in 2013 an anonymous survey was conducted among 955...

Simulating Silicon Photomultiplier Response to Scintillation Light.

IEEE transactions on nuclear science

Jha AK, van Dam HT, Kupinski MA, Clarkson E.
PMID: 26236040
IEEE Trans Nucl Sci. 2013 Feb;30(1):336-351. doi: 10.1109/TNS.2012.2234135.

The response of a Silicon Photomultiplier (SiPM) to optical signals is affected by many factors including photon-detection efficiency, recovery time, gain, optical crosstalk, afterpulsing, dark count, and detector dead time. Many of these parameters vary with overvoltage and temperature....

Post-lumpectomy CT-guided tumor bed delineation for breast boost and partial breast irradiation: Can additional pre- and postoperative imaging reduce interobserver variability?.

Oncology letters

DEN Hartogh MD, Philippens ME, VAN Dam IE, Kleynen CE, Tersteeg RJ, Kotte AN, VAN Vulpen M, VAN Asselen B, VAN DEN Bongard DH.
PMID: 26722244
Oncol Lett. 2015 Nov;10(5):2795-2801. doi: 10.3892/ol.2015.3697. Epub 2015 Sep 14.

For breast boost radiotherapy or accelerated partial breast irradiation, the tumor bed (TB) is delineated by the radiation oncologist on a planning computed tomography (CT) scan. The aim of the present study was to investigate whether the interobserver variability...

Mechanical Stress Changes the Complex Interplay Between HO-1, Inflammation and Fibrosis, During Excisional Wound Repair.

Frontiers in medicine

Cremers NA, Suttorp M, Gerritsen MM, Wong RJ, van Run-van Breda C, van Dam GM, Brouwer KM, Kuijpers-Jagtman AM, Carels CE, Lundvig DM, Wagener FA.
PMID: 26697429
Front Med (Lausanne). 2015 Dec 15;2:86. doi: 10.3389/fmed.2015.00086. eCollection 2015.

Mechanical stress following surgery or injury can promote pathological wound healing and fibrosis, and lead to functional loss and esthetic problems. Splinted excisional wounds can be used as a model for inducing mechanical stress. The cytoprotective enzyme heme oxygenase-1...

Starting SCF calculations by superposition of atomic densities.

Journal of computational chemistry

Van Lenthe JH, Zwaans R, Van Dam HJ, Guest MF.
PMID: 16557519
J Comput Chem. 2006 Jun;27(8):926-32. doi: 10.1002/jcc.20393.

We describe the procedure to start an SCF calculation of the general type from a sum of atomic electron densities, as implemented in GAMESS-UK. Although the procedure is well known for closed-shell calculations and was already suggested when the...

Tunable supercurrent through semiconductor nanowires.

Science (New York, N.Y.)

Doh YJ, van Dam JA, Roest AL, Bakkers EP, Kouwenhoven LP, De Franceschi S.
PMID: 16002611
Science. 2005 Jul 08;309(5732):272-5. doi: 10.1126/science.1113523.

Nanoscale superconductor/semiconductor hybrid devices are assembled from indium arsenide semiconductor nanowires individually contacted by aluminum-based superconductor electrodes. Below 1 kelvin, the high transparency of the contacts gives rise to proximity-induced superconductivity. The nanowires form superconducting weak links operating as...

Quantum supercurrent transistors in carbon nanotubes.

Nature

Jarillo-Herrero P, van Dam JA, Kouwenhoven LP.
PMID: 16495994
Nature. 2006 Feb 23;439(7079):953-6. doi: 10.1038/nature04550.

Electronic transport through nanostructures is greatly affected by the presence of superconducting leads. If the interface between the nanostructure and the superconductors is sufficiently transparent, a dissipationless current (supercurrent) can flow through the device owing to the Josephson effect....

Mathematical model of fluorescence endoscopic image formation.

Applied optics

Wang TD, Janes GS, Wang Y, Itzkan I, Van Dam J, Feld MS.
PMID: 18301704
Appl Opt. 1998 Dec 01;37(34):8103-11. doi: 10.1364/ao.37.008103.

We present a mathematical model that describes the spatial distribution of photons in fluorescence endoscopic images, resulting in expressions for image signal-to-noise ratio and resolution. This model was applied to quantitative analysis of fluorescence images collected from human colonic...
