Students’understanding of the concept of the electric field through conversions of multiple representations
(American Physical Society, 2020-06-04)
We conducted a study with introductory and upper-division level physics students in a Mexican and a Spanish university to learn how students recognize the main characteristics of the electric field in three of its more ...
The Y-chromosome of the Soliga, an ancient forest-dwelling tribe of South India
(Elsevier, 2020)
A previous autosomal STR study provided evidence of a connection between the ancient Soliga tribe at the southern tip of the Indian subcontinent and Australian aboriginal populations, possibly reflecting an eastbound coastal ...
Ready Access to Molecular Rotors Based on Boron Dipyrromethene Dyes-Coumarin Dyads Featuring Broadband Absorption
(MDPI, 2020-02-12)
Herein we report on a straightforward access method for boron dipyrromethene dyes (BODIPYs)-coumarin hybrids linked through their respective 8- and 6- positions, with wide functionalization of the coumarin fragment, using ...
An engineered coccolith-based hybrid that transforms light into swarming motion
(Elsevier ; Cell Press, 2021-03-24)
[EN] Translating energy into swarming motion for miniature entities remains
a challenge. This translation requires simultaneously breaking
the symmetry of the system to enable locomotion and a coupling effect
between ...
Search for B-s(0) -> eta'Xs(s)over-bar at Belle using a semi-inclusive method
(American Physical Society, 2021-07-12)
We report the first search for the penguin-dominated process B-s(0) -> eta'X(s ()s() over bar) using a semi-inclusive method. A 121.4 fb-1 integrated luminosity gamma(5S) data set collected by the Belle experiment, at the ...
Characterization, Stability, and Bioaccessibility of Betalain and Phenolic Compounds from Opuntia stricta var. Dillenii Fruits and Products of Their Industrialization
(MDPI, 2021-07-09)
The aim of the present study was the full characterization, quantification, and determination of the digestive stability and bioaccessibility of individual betalain and phenolic compounds of Opuntia stricta, var. Dillenii ...
Contextualization of the Bioeconomy Concept through Its Links with Related Concepts and the Challenges Facing Humanity
(MDPI, 2021-07-12)
The concept of bioeconomy is a topic of debate, confusion, skepticism, and criticism. Paradoxically, this is not necessarily a negative thing as it is encouraging a fruitful exchange of information, ideas, knowledge, and ...
Genotyping-by-sequencing resolves relationships in Polygonaceae tribe Eriogoneae
(Wiley, 2021-08)
The resolution of cryptic diversity is essential for understanding the evolutionary diversification of lineages and establishing conservation priorities. We examine relationships in Eriogoneae (Polygonaceae), a diverse ...
Crowding Effects on the Structure and Dynamics of the Intrinsically Disordered Nuclear Chromatin Protein NUPR1
(Frontiers Media, 2021-07-05)
The intracellular environment is crowded with macromolecules, including sugars, proteins and nucleic acids. In the cytoplasm, crowding effects are capable of excluding up to 40% of the volume available to any macromolecule ...
Phase transitions of alkaline-earth metal sulfides under pressure
(IOP Publishing Ltd., 2021-06-21)
[EN] Wehave systematically explored the crystal structures of alkaline-earth metal sulfides under pressure
by using a swarm-intelligence structural prediction method. At low pressures we successfully
reproduced their ...
