Graphical Normalizing Flows [PDF]

open access: yesarXiv, 2020
Normalizing flows model complex probability distributions by combining a base distribution with a series of bijective neural networks. State-of-the-art architectures rely on coupling and autoregressive transformations to lift up invertible functions from scalars to vectors.

Small Molecule X‐ray Crystal Structures at a Crossroads

open access: yesChemistry–Methods, EarlyView.
Accompanying text: After 110 years of constant improvements in hardware and software for data measurement, it is now necessary to improve the model that SC‐XRD data are fit to. This creates a ‘crossroads’ – a choice between the old independent atom model and newer approaches.

3D Primitives Gpgpu Generation for Volume Visualization in 3D Graphics Systems [PDF]

open access: yesjournal of king abdulaziz university computing and information technology sciences, Vol. 9, issue 2, 2020, 2020
This article discusses the study of 3D graphic volume primitive computer system generation (3D segments) based on General Purpose Graphics Processing Unit (GPGPU) technology for 3D volume visualization systems. It is based on the general method of Volume 3D primitive generation and an algorithm for the voxelization of 3D lines, previously proposed and ...

Monitoring Nanostructural Dynamics During the Electrochemical Growth of Metal Hydroxide Thin Films by in‐situ Small‐Angle X‐Ray Scattering

open access: yesChemistry–Methods, EarlyView.
We present a custom‐built electrochemical flow cell for in‐house real‐time small‐angle X‐ray scattering (SAXS) experiments to monitor the electrocrystallization of nanoscale Co(OH)2 platelets tracking their growth from 7.8 nm to 15.7 nm thickness. Citrate ligands initially stabilize spherical structures, transitioning to platelet morphologies as the ...

An Expectation Conditional Maximization approach for Gaussian graphical models [PDF]

open access: yesarXiv, 2017
Bayesian graphical models are a useful tool for understanding dependence relationships among many variables, particularly in situations with external prior information. In high-dimensional settings, the space of possible graphs becomes enormous, rendering even state-of-the-art Bayesian stochastic search computationally infeasible.

Towards a Model of Color Reproduction Difference

open access: yesColor Research &Application, EarlyView.
ABSTRACT It is difficult to predict the visual difference between cross‐media color reproductions. Typically, visual difference occurs due to the limitations of each output medium's color gamut, the difference in substrate colors, and the gamut mapping operations used to transform the source material.

Thermal, surface and mechanical properties of PCL/PLA composites with coconut fibres as an alternative material to photopolymer printing plates

open access: yesTehnički Glasnik, 2017
In this paper, methods of thermal, mechanical and surface analyses of biodegradable PCL/PLA composites with the addition of different concentrations of coconut fibres were performed.

Origins of Human Graphic Art [PDF]

open access: yesNature, 1942
As a result of the publication of my note in NATURE of June 6, p. 637, Mr. J. Leonard Bowen, of Port Sunlight, Cheshire, sent me the enclosed letter which seemed to me of such interest that I have obtained his permission to publish it in NATURE. Mr. Bowen tells me that the monkeys were almost certainly the common rhesus monkey, Macaca mulatta.

Unveiling the Materiality of 19th Century's Color Spaces

open access: yesColor Research &Application, EarlyView.
ABSTRACT Several color theories flourished during the 19th century, marked by experiments on the distinction between color‐light and color‐matter. This study aims to compare the color plates designed to illustrate three of these color theories, namely M.E. Chevreul's chromatic circle (1861), O. Rood's frontispiece (1879), and C.
