PMID: 28924696
EJNMMI Phys. 2017 Sep 18;4(1):23. doi: 10.1186/s40658-017-0190-7.

To date, there is no published detailed checklist with parameters referencing the DICOM tag information with respect to the quality control (QC) of PET/CT scans. The aims of these guidelines are to provide the know-how for effectively controlling the...

La3N@C92: An Endohedral Metallofullerene Governed by Kinetic Factors?.

Inorganic chemistry

Abella L, Mulet-Gas M, Rodríguez-Fortea A, Poblet JM.
PMID: 27002381
Inorg Chem. 2016 Apr 04;55(7):3302-6. doi: 10.1021/acs.inorgchem.5b02414. Epub 2016 Mar 22.

Different structures have been proposed so far for the C92 isomer that encapsulates M3N (M = La, Ce, Pr). We show here that the electrochemical properties of the predicted most abundant (thermodynamic) isomer for La3N@C92 does not agree with...

Visual and instrumental correlation of sparkle by the magnitude estimation method.

Applied optics

Gómez O, Perales E, Chorro E, Viqueira V, Martínez-Verdú FM.
PMID: 27534495
Appl Opt. 2016 Aug 10;55(23):6458-63. doi: 10.1364/AO.55.006458.

Most real surfaces and objects show variations in appearance with viewing and illumination directions. Besides angular dependency, they also show spatial variation in color, i.e., they exhibit some sort of texture. Of the surfaces we see, surfaces colored by...

Genetic Association of Hematopoietic Stem Cell Transplantation Outcome beyond Histocompatibility Genes.

Frontiers in immunology

Gam R, Shah P, Crossland RE, Norden J, Dickinson AM, Dressel R.
PMID: 28421078
Front Immunol. 2017 Apr 03;8:380. doi: 10.3389/fimmu.2017.00380. eCollection 2017.

The outcome of hematopoietic stem cell transplantation (HSCT) is controlled by genetic factors among which the leukocyte antigen human leukocyte antigen (HLA) matching is most important. In addition, minor histocompatibility antigens and non-HLA gene polymorphisms in genes controlling immune...

Psychometric properties of the Trauma and Distress Scale, TADS, in an adult community sample in Finland.

European journal of psychotraumatology

Eur J Psychotraumatol. 2016 Mar 30;7:30062. doi: 10.3402/ejpt.v7.30062. eCollection 2016.

BACKGROUND: There is increasing evidence that a history of childhood abuse and neglect is not uncommon among individuals who experience mental disorder and that childhood trauma experiences are associated with adult psychopathology. Although several interview and self-report instruments for...

Complex Behavior of Caffeine Crystallites on Muscovite Mica Surfaces.

Crystal growth & design

Röthel C, Radziown M, Resel R, Zimmer A, Simbrunner C, Werzer O.
PMID: 26366127
Cryst Growth Des. 2015 Sep 02;15(9):4563-4570. doi: 10.1021/acs.cgd.5b00833. Epub 2015 Jul 31.

Defined fabrication of organic thin films is highly desired in technological, as well as pharmaceutical, applications since morphology and crystal structure are directly linked to physical, electrical, and optical properties. Within this work, the directed growth of caffeine deposited...

Modeling "wiggling" as a multi-path interference problem in AMCW ToF imaging.

Optics express

Feigin M, Whyte R, Bhandari A, Dorington A, Raskar R.
PMID: 26367583
Opt Express. 2015 Jul 27;23(15):19213-25. doi: 10.1364/OE.23.019213.

Amplitude modulated continuous wave time-of-flight range cameras suffer from an inherent depth measurement error due to aliasing of the emitted signal vs reference signal correlation function. This is due to higher harmonics present in both signals which are not...

Stereovision-based integrated system for point cloud reconstruction and simulated brain shift validation.

Journal of medical imaging (Bellingham, Wash.)

Yang X, Clements LW, Luo M, Narasimhan S, Thompson RC, Dawant BM, Miga MI.
