TL;DR: The SHINE toolbox for MATLAB features functions for specifying the (rotational average of the) Fourier amplitude spectra, for normalizing and scaling mean luminance and contrast, and for exact histogram specification optimized for perceptual visual quality.
Abstract: Visual perception can be influenced by top-down processes related to the observer’s goals and expectations, as well as by bottom-up processes related to low-level stimulus attributes, such as luminance, contrast, and spatial frequency. When using different physical stimuli across psychological conditions, one faces the problem of disentangling the contributions of low- and high-level factors. Here, we make available the SHINE (spectrum, histogram, and intensity normalization and equalization) toolbox for MATLAB, which we have found useful for controlling a number of image properties separately or simultaneously. The toolbox features functions for specifying the (rotational average of the) Fourier amplitude spectra, for normalizing and scaling mean luminance and contrast, and for exact histogram specification optimized for perceptual visual quality. SHINE can thus be employed for parametrically modifying a number of image properties or for equating them across stimuli to minimize potential low-level confounds in studies on higher level processes.

TL;DR: Efficient sampling of mutations likely to affect enzyme function has been conducted both experimentally and computationally, with remarkable improvements in substrate selectivity and specificity and in the de novo design of enzyme activities within scaffolds of known structure.

TL;DR: The authors investigate evaluation metrics for dialogue response generation systems where supervised labels, such as task completion, are not available, and provide qualitative and quantitative results highlighting specific weaknesses in existing metrics and provide recommendations for future development of better automatic evaluation metrics.
Abstract: We investigate evaluation metrics for dialogue response generation systems where supervised labels, such as task completion, are not available. Recent works in response generation have adopted metrics from machine translation to compare a model's generated response to a single target response. We show that these metrics correlate very weakly with human judgements in the non-technical Twitter domain, and not at all in the technical Ubuntu domain. We provide quantitative and qualitative results highlighting specific weaknesses in existing metrics, and provide recommendations for future development of better automatic evaluation metrics for dialogue systems.

TL;DR: The authors found that activation of unmyelinated tactile (CT) afferents produced a faint sensation of pleasant touch, which may underlie emotional, hormonal and affiliative responses to skin-to-skin contact between individuals.
Abstract: There is dual tactile innervation of the human hairy skin: in addition to fast-conducting myelinated afferent fibers, there is a system of slow-conducting unmyelinated (C) afferents that respond to light touch. In a unique patient lacking large myelinated afferents, we found that activation of C tactile (CT) afferents produced a faint sensation of pleasant touch. Functional magnetic resonance imaging (fMRI) analysis during CT stimulation showed activation of the insular region, but not of somatosensory areas S1 and S2. These findings identify CT as a system for limbic touch that may underlie emotional, hormonal and affiliative responses to caress-like, skin-to-skin contact between individuals.

TL;DR: It is argued that population-approach interventions may be compromised by inconsistencies between the social and cultural assumptions of public health practitioners and targeted groups and some intervention principles are proposed to mitigate the health disparities associated with population- Approaches interventions.
Abstract: Using the concept of vulnerable populations, we examine how disparities in health may be exacerbated by populationapproach interventions. We show, from an etiologic perspective,howlife-course epidemiology, the concentration of risk factors, and the concept of fundamental causes of diseases may explain the differential capacity, throughout the risk-exposure distribution, to transform resources provided through population-approach interventions into health. From an intervention perspective, we argue that population-approach interventions may be compromised by inconsistencies between the social and cultural assumptions of public health practitioners and targeted groups. We propose some intervention principles to mitigate the health disparities associated with population-approach interventions.
