Understanding Lightness and Brightness in Different Media

open access: yes, 2022
This thesis aimed to study how lightness and brightness perception relate to each other. We used a simple task to study whether observers perceive lightness and brightness to be different percepts and what cues they use to make these judgments.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

The Effect of the Slaughter Weight on Carcass Composition, Body Measurements and Veal Quality of Holstein Calves

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2019
The aim of this study was to investigate the growth, fattening characteristics and veal quality of MLT from Holstein calves (total number of 40 heads) produced from 4 slaughter weight groups (130, 150, 180 and 210 kg).

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Calculating Retinal Contrast from Scene Content: A Program

open access: yesFrontiers in Psychology, 2018
This paper describes a computer program for calculating the contrast image on the human retina from an array of scene luminances. We used achromatic transparency targets and measured test target's luminances with meters.

Approaches to Surface-evaluation of Compressive Strength of Concrete in Structure Based on Lightness Changing on Concrete Surface by Water Sprinkling

open access: yes, 2013
This paper is reported the result of approaches to nondestructive surface-evaluation of concrete in structure by comparing with strength of core and estimated strength based on lightness changing of concrete surface by water sprinkling.

Perceptual grouping-dependent lightness processing in human early visual cortex [PDF]

open access: yes, 2010
Lightness, the perceived relative achromatic reectance of a surface, depends strongly on the context within which the surface is viewed. Modest changes in the two-dimensional conguration or three-dimensional scene geometry may lead to profound variations

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
