Automatic Image Registration Provides Superior Accuracy Compared with Surface Matching in Cranial Navigation

open access: yesSensors
Objective: The precision of neuronavigation systems relies on the correct registration of the patient’s position in space and aligning it with radiological 3D imaging data.

Frames of Reference in Social Cognition

open access: yesQuarterly Journal of Experimental Psychology, 2008
How is mindreading affected by social context? It is often implicitly assumed that there is one single way to understand others, whatever the situation or the identity of the person. In contrast, I emphasize the duality of functions of mindreading depending on the context (social interaction and social observation), as well as the duality of social ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

SIRGAS 2017 reference frame realization SIR17P01 [PDF]

open access: yes, 2020
The SIRGAS reference frame realization (SIR17P01) covers the period from April 17, 2011 (GPS week 1632) to January 28, 2017 (GPS week 1933). It includes only weekly solutions referring to the IGS08/IGb08 reference frame.

Balinese Frame of Reference

open access: yesJurnal Kajian Bali (Journal of Bali Studies), 2016
: Balinese Frame of Reference. Wassmann and Dasen (1998) did a study on the acquisition of Balinese frames of reference. They pointed out that, in addition to the dominant use of absolute system, the use of relative system was also observed. This article

Roles of the Retinotopic and Environmental Frames of Reference on Vection

open access: yesFrontiers in Virtual Reality, 2020
Humans perceive self-motion using multisensory information, while vision has a dominant role as is utilized in virtual reality (VR) technologies. Previous studies reported that visual motion presented in the lower visual field (LoVF) induces stronger ...

The Effects of the IERS Conventions (2010) on High Precision Orbit Propagation [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2014
The Earth is not perfectly spherical and its rotational axis is not fixed in space, and these geophysical and kinematic irregularities work as dominant perturbations in satellite orbit propagation.

Egocentric and Allocentric Reference Frames Can Flexibly Support Contextual Cueing

open access: yesFrontiers in Psychology, 2021
We investigated if contextual cueing can be guided by egocentric and allocentric reference frames. Combinations of search configurations and external frame orientations were learned during a training phase.

Reference Frames [PDF]

open access: yesSymposium - International Astronomical Union, 1996
After a short introduction on the definition and the construction of a reference frame, the presentation concentrates on the actual construction of the new IAU conventional reference frame. The 1991 IAU resolutions on reference systems is reviewed and the present state of the implementation of these resolutions is discussed.
