Origin and characterization of cyclodepsipeptides: Comprehensive structural approaches with focus on mass spectrometry analysis of alkali‐cationized molecular species

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract Cyclodepsipeptides (CDPs) represent a huge family of chemically and structurally diverse molecules with a wide ability for molecular interactions. CDPs are cyclic peptide‐related natural products made up of both proteinogenic and nonproteinogenic amino acids linked by amide and ester bonds.

Asymptotic Analysis of Stokes Flow Through a Filter

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper investigates the Stokes flow through a thin porous layer composed of a rigid, thin, periodic, and closely packed array of parallel long rods with a noncircular, anisotropic cross‐section in the shape of a slot. This shape allows for the construction of a thicker permeable filter than what is known as the Brinkman critical size.

Bridging biodiversity and ecosystem services through useful plant species

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Global change endangers the terrestrial vegetation that sustains us. Therefore, policymakers need to make informed decisions about what and where to protect. However, with limited resources, we must decide whether to protect the intrinsic value of plants or their value to humans. Protecting both is possible.

Totally spies!

open access: yes, 2022
La cultura visual, como disciplina encargada del análisis de las imágenes fijas y en movimiento, estudia la implicación y el impacto del discurso iconográfico de productos (audio)visuales en quienes los consumen. Asimismo, se esfuerza por discutir los discursos que dichos recursos, entre otros televisivos, difunden. Se parte de un posicionamiento socio-

A V‐Shaped In‐Pipe Robot to Travel Through Complex Winding Pathways in Three Dimensions

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT This paper presents a V‐shaped gas pipeline inspection robot which achieves high roll rotation performance, out‐of‐plane double elbow travel performance, and inverted siphon adaptability at high speed without requiring complicated manual operation. The principle for traveling through the out‐of‐plane double elbow was theoretically demonstrated
