Exocentric Pointing in the Visual Field [PDF]

open access: yesi-Perception, 2013
“Exocentric pointing in the visual field” involves the setting of a pointer so as to visually point to a target, where both pointer and target are objects in the visual field. Phenomenologically, such pointings show systematic deviations from veridicality of several degrees.

Endoglin mediates the tumor‐ and metastasis‐promoting traits of stromal myofibroblasts in human breast carcinomas

open access: yesMolecular Oncology, EarlyView.
Carcinoma‐associated fibroblasts (CAFs) in tumors influence cancer progression. We identified endoglin (ENG) as a key factor in TGF‐β signaling in myofibroblastic CAFs (myCAFs), linked to poor breast cancer outcomes. Inhibiting ENG on myCAFs suppressed the TGF‐β‐Smad2/3 pathway, reducing primary tumor growth and metastasis.

A Method to Evaluate the Stimulation of a Real World Field of View by Means of a Spectroradiometric Analysis [PDF]

open access: yes, 2015
Stimulation elicited by a real world field of view is related to the color, the intensity and the direction of the information reaching the eye: different spectral power distributions of light trigger different responses. An evaluation of the stimulation

Bridging the gap: Multi‐stakeholder perspectives of molecular diagnostics in oncology

open access: yesMolecular Oncology, EarlyView.
Although molecular diagnostics is transforming cancer care, implementing novel technologies remains challenging. This study identifies unmet needs and technology requirements through a two‐step stakeholder involvement. Liquid biopsies for monitoring applications and predictive biomarker testing emerge as key unmet needs. Technology requirements vary by

The Orientation of Visual Space from the Perspective of Hummingbirds

open access: yesFrontiers in Neuroscience, 2018
Vision is a key component of hummingbird behavior. Hummingbirds hover in front of flowers, guide their bills into them for foraging, and maneuver backwards to undock from them.

Estimating Sensor Motion from Wide-Field Optical Flow on a Log-Dipolar Sensor [PDF]

open access: yes, 2004
Log-polar image architectures, motivated by the structure of the human visual field, have long been investigated in computer vision for use in estimating motion parameters from an optical flow vector field. Practical problems with this approach have been:

Sensitivity to Timing and Order in Human Visual Cortex [PDF]

open access: yes, 2014
Visual recognition takes a small fraction of a second and relies on the cascade of signals along the ventral visual stream. Given the rapid path through multiple processing steps between photoreceptors and higher visual areas, information must progress ...

Understanding and measuring mechanical signals in the tumor stroma

open access: yesFEBS 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 ...

Lateralization of Executive Function: Working Memory Advantage for Same Hemifield Stimuli in the Monkey

open access: yesFrontiers in Neuroscience, 2017
Working memory capacity, the amount of information that may be maintained in mind over a period of seconds, is extremely limited, to a handful of items.

Visual sensitivity tester [PDF]

open access: yes, 1972
Testing device uses closed loop film cassettes to project programmed visual stimuli on screen which the observer views through a lens making the stimuli appear to be at optical infinity.
