The Effect of Suvorexant on Fear Extinction Recall: A Double-Blind Randomised Controlled Pilot Trial in Healthy Individuals. [PDF]
J Sleep ResABSTRACT Post‐traumatic stress disorder (PTSD) is a highly debilitating condition that develops after trauma exposure. Dysregulation in extinction memory consolidation (i.e., the ability to remember that trauma‐related stimuli no longer signal danger) is proposed to underlie PTSD development. Disruptions in rapid eye movement (REM) sleep are thought to

On the extension of Helmert transform [PDF]
Advances in Astronomy and Space Physics, 2014 The article deals with the method of comparison of the coordinate systems used by two quite different scientific disciplines: stellar astronomy and the geodesy. Geodesic Helmert transform is analysed along with a series of stellar astronomy kinematic models: Kovalsky-Airy, Lindbladt-Oort and Ogorodnikov-Milne.

Converted Total Least Squares method and Gauss-Helmert model with applications to transformation among ITRF realizations [PDF]
, 2019 This thesis is an extension and improvement of the theory and applications of Converted Total Least Squares method (CTLS). Converted Total Least Squares (CTLS) dealing with the errors-in-variables (EIV) model take the stochastic design matrix elements as

Standard deviations of coordinates due transformation between ellipsoids [PDF]
Podzemni Radovi, 2017 Transformation between ellipsoids also called datum transformation implies coordinate conversion from one ellipsoid to another ellipsoid, most frequently to be done by Helmert seven-parameter transformation.

AUTOMATED ALIGNMENT OF LOCAL POINT CLOUDS IN DIGITAL BUILDING MODELS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019 For the correct usage and analysis within a BIM environment, image-based point clouds that were created with Structure from Motion (SfM) tools have to be transformed into the building coordinate system via a seven parameter Helmert Transformation ...

INTEGRATION OF PHOTOGRAMMETRY, COMPUTED TOMOGRAPHY AND ENDOSCOPY FOR GYROSCOPE 3D DIGITIZATION [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021 Cultural heritage preservation via 3D digitization is becoming more and more important. Besides conventional buildings and landmarks, many technical instruments and artifacts, which belong to tech heritage (TH), are also of great importance, historically

IMAGE QUALITY IMPROVEMENTS IN LOW-COST UNDERWATER PHOTOGRAMMETRY [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019 This study presents an evaluation of a cheap consumer-grade camera used for modelling a coral reef section. We evaluate the quality of a reconstructed coral reef using GoPro cameras and a high-end camera with data from an actual coral reef dataset.

Least Squares Collocation Alternative to Helmert’s Transformation with Hausbrandt’s Post – Transformation Correction [PDF]
Reports on Geodesy and Geoinformatics, 2015 Abstract The paper presents a least squares collocation - based alternative to Helmert’s transformation with Hausbrandt’s post – transformation correction. The least squares collocation is used as an exact predictor i.e. it honors the data, thus the problem of zero residuals on transformation control points is overcome and zero ...
