On Grinbergs' differential geometry and finite fields
(2019-03-27)
Emanuels Grinbergs, in his youth, during ten years, from 1933 until 1943, wrote three dissertations on one subject, namely, differential geometry [1, 2, 3]. We think that his work in this direction has been neglected for ...
Using 2-colorings in the theory of uniquely Hamiltonian graphs
(2019-02)
We use the concept of 2-coloring in analyzing UH3 graphs and building exact specifications of functions to find new UH3 graphs by Hamiltonian cycle edge extractions
On Grinberg’s Criterion
(Universiteit Gent, Faculty of Science, 2019)
We generalize Grinberg’s hamiltonicity criterion for planar graphs. To this end, we first prove a technical theorem for embedded graphs. As a special case of a corollary of this theorem we obtain Zaks’ extension of Grinberg’s ...

Biophotonics in veterinary medicine: the first steps toward clinical translation
(SPIE, 2019-02-20)
In this paper, we analyzed the current situation and the potential of biophotonics and biomedical optics in veterinary
medicine. Promising optical techniques such as optical coherence tomography, pulse oximeter, and ...
Photoplethysmography in dogs and cats: a selection of alternative measurement sites for a pet monitor
(IOP Publishing, 2019-01-22)
Objective: Photoplethysmography (PPG) is an increasingly popular health and well-being tool for monitoring heart rate and oxygen saturation. Due to the pigmentation and hairiness of dogs and cats, a pulse oximeter is ...
Poor optical stability of molecular dyes when used as absorbers in water-based tissue-simulating phantoms
(SPIE, 2019-02-27)
Biomedical optical systems and models can be easily validated by the use of tissue-simulating phantoms. They can
consist of water-based turbid media which often include inks (India ink and molecular dyes) as absorbers. ...
Clinical evaluation of automated capillary refill time estimation in dogs and cats
(SPIE, 2019-02-26)
In this study, we clinically evaluated a pulse oximeter-based device for automated capillary refill time (CRT) estimation
in dogs and cats. CRT can reveal conditions like shock or anemia in dogs and cats. However, visual ...

Cyclic moisture sorption and its effects on the thermomechanical properties of epoxy and epoxy/MWCNT nanocomposite
(MDPI, 2019-08-23)
The aim of this work was to reveal the moisture absorption–desorption–resorption
characteristics of epoxy and epoxy-based nanocomposites filled with different multiwall
carbon nanotubes (MWCNTs) by investigating the ...
