Understanding and measuring mechanical signals in the tumor stroma
FEBS Open Bio, EarlyView.This review discusses cancer‐associated fibroblast subtypes and their functions, particularly in relation to extracellular matrix production, as well as the development of 3D models to study tumor stroma mechanics in vitro. Several quantitative techniques to measure tissue mechanical properties are also described, to emphasize the diagnostic and ...

Temporal Integration of Motion Streaks in Migraine
Vision, 2018 Migraine is associated with differences in visual perception, specifically, deficits in the perception of motion. Migraine groups commonly show poorer performance (higher thresholds) on global motion tasks compared to control groups.

Simulating vibration transmission and comfort in automated driving integrating models of seat, body, postural stabilization and motion perception [PDF]
arXiv, 2023 To enhance motion comfort in (automated) driving we present biomechanical models and demonstrate their ability to capture vibration transmission from seat to trunk and head. A computationally efficient full body model is presented, able to operate in real time while capturing translational and rotational motion of trunk and head with fore-aft, lateral ...

The effect of experience and of dots\u2019 density and duration on the detection of coherent motion in dogs [PDF]
, 2018 Knowledge about the mechanisms underlying canine vision is far from being exhaustive, especially that concerning post- retinal elaboration. One aspect that has received little attention is motion perception, and in spite of the common belief that dogs ...

Noninvasive Assessment of the Visual System, 1992 The early detection of optic nerve damage is a prerequisite for effective therapy in primary open-angle glaucoma (Kass et al., 1990). An alarmingly large proportion of retinal ganglion cells may be damaged, however, before visual field defects are observed with conventional manual or automated perimetry (Quigley et al., 1982; Quigley et al., 1989 ...

Move or Push? Studying Pseudo-Haptic Perceptions Obtained with Motion or Force Input [PDF]
arXiv, 2023 Pseudo-haptics techniques are interesting alternatives for generating haptic perceptions, which entails the manipulation of haptic perception through the appropriate alteration of primarily visual feedback in response to body movements. However, the use of pseudo-haptics techniques with a motion-input system can sometimes be limited.

Five‐year evaluation of linear accelerator‐based SRS platform isocentricity
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Linear accelerator (LINAC)‐based stereotactic radiosurgery (SRS) has become a mainstay in the management of intracranial tumors. However, the high fractional doses and sharp gradients used in SRS place heavy demands on geometric accuracy.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background Various methods exist to correct for intrafraction motion (IFM) of the prostate during radiotherapy. We sought to characterize setup corrections in our practice informed by the TrueBeam Advanced imaging package, and analyze factors associated with IFM.

Frontiers in Computational Neuroscience, 2019 This article develops a model of how reactive and planned behaviors interact in real time. Controllers for both animals and animats need reactive mechanisms for exploration, and learned plans to efficiently reach goal objects once an environment becomes ...
