Genome and evolution of Prosopis alba Griseb., a drought and salinity tolerant tree legume crop for arid climates

open access: yesPLANTS, PEOPLE, PLANET, Volume 5, Issue 6, Page 933-947, November 2023., 2023
Society anticipates a world in which more food and fiber must be produced at warmer temperatures, which, on the contrary, have greater constraints on the use of water and fertilizers. Tree legumes are often the climax vegetation on the semi‐arid and arid lands, covering ~25% of the planet, but the knowledge of their genomes is limited.

Los petrograbados y la técnica del gnomon como registro solar de marcadores astronómico-calendáricos en sitios del centro-norte de Mesoamérica

open access: yesBulletin de l'Institut Français d'Études Andines, 2020
This proposal addresses the study of stone engravings and the implementation of gnomon as a technique that specifies precise orientations, solar dates and associations between the motifs recorded in different rocky matrices at a pair of prehispanic ...

Evolution of five environmentally responsive gene families in a pine‐feeding sawfly, Neodiprion lecontei (Hymenoptera: Diprionidae)

open access: yesEcology and Evolution, Volume 13, Issue 10, October 2023., 2023
We examine the predictability of gene family size changes in the pine tree specialist Neodiprion lecontei. Overall, our results are consistent with predictable gene family expansions and contractions in response to novel selection pressures. Abstract A central goal in evolutionary biology is to determine the predictability of adaptive genetic changes ...

Neural Shading Fields for Efficient Facial Inverse Rendering

open access: yesComputer Graphics Forum, Volume 42, Issue 7, October 2023., 2023
Abstract Given a set of unstructured photographs of a subject under unknown lighting, 3D geometry reconstruction is relatively easy, but reflectance estimation remains a challenge. This is because it requires disentangling lighting from reflectance in the ambiguous observations.

Dust Deposition at Zhurong Landing Site From Multispectral Camera Observations

open access: yesGeophysical Research Letters, Volume 50, Issue 13, 16 July 2023., 2023
Abstract Dust deposition is one of the most predominant processes occurring on Mars. Until now, just a few in situ observations have been conducted to investigate the Martian dust. The Multispectral Camera (MSCam) onboard the Zhurong rover with its calibration target can be used to monitor dust deposition, providing a new ground observation.

Pitfalls of using sequence databases for heterologous expression studies – a technical review

open access: yesThe Journal of Physiology, Volume 601, Issue 9, Page 1611-1623, 1 May 2023., 2023
Abstract figure legend Projects involving heterologous gene expression are often characterised by similar steps. Initially, database research (A) is necessary to retrieve information of full or partial sequences of a gene of interest. A multitude of genome assemblies are annotated and deposited in public databases or are available for refined search ...

Finding SEIS North on Mars: Comparisons Between SEIS Sundial, Inertial and Imaging Measurements and Consequences for Seismic Analysis

open access: yesEarth and Space Science, 2021
In this paper, we present the results obtained in the determination of the true north direction on Mars by using a gnomon on the InSight mission and compare the measurements with either the North determination from the Inertial Measurement Unit and ...
