Parameterized absorptive electron scattering factors. [PDF]
Acta Crystallogr A Found AdvThis paper provides a rapid parameterized calculation of absorptive scattering factors for 103 elements as neutral, spherical atoms, which reduces calculation time considerably.In electron diffraction, thermal atomic motion produces incoherent scattering over a relatively wide angular range, which appears as a diffuse background that is usually ...

JCCM: Joint conformer and CNN model for overlapping radio signals recognition
Electronics Letters, Volume 59, Issue 21, November 2023., 2023 The traditional blind signal separation (BSS) method is mostly not effective when both radio propagation effects and low signal‐to‐noise ratio (SNR) scenarios are taken into consideration. In this letter, joint conformer and CNN model (JCCM) is proposed to separate and recognize the overlapping radio signals which are also unknown by the monitor node ...

L’image de la Chinoise « désexuée » sous le regard de Beauvoir : De la critique à l’idéalisation
Orbis Litterarum, Volume 78, Issue 4, Page 315-326, August 2023., 2023 Résumé Dans La longue marche, essai sur la Chine (Gallimard, 1957), malgré son admiration pour le pays maoïste, Beauvoir aborde un phénomène social controversé qui est la « désexualisation » de la femme chinoise. La réception beauvoirienne, en cette matière, est assez particulière, car elle témoigne d’une rupture entre l’horizon d’attente et le présent.

TAXON, Volume 72, Issue 2, Page 261-277, April 2023., 2023 Abstract The grape hyacinth (Muscari) represents an important ornamental plant group in Asparagaceae subfamily Scilloideae, comprising some 80 species distributed mainly in the Mediterranean. However, genus delimitation has repeatedly shifted over the past two centuries and a general consensus has not been reached so far. The present study investigates

A re‐examination of the circumscription of Saxifraga mengtzeana (Saxifragaceae)
Ecology and Evolution, Volume 13, Issue 3, March 2023., 2023 Integrating morphological, geographical, and molecular evidence, we reinterpret the taxonomic and phylogenetic status of Saxifraga mengtzeana and related taxa. Our data suggest that Saxifraga epiphylla is part of a polymorphism and should be synonymized under Saxifraga mengtzeana and that Saxifraga geifolia should be distinct rather than conspecific ...

Chloroplast phylogenomics and the taxonomy of Saxifraga section Ciliatae (Saxifragaceae)
Ecology and Evolution, Volume 13, Issue 1, January 2023., 2023 Subdivisions of sect. Ciliatae proposed in various taxonomic systems have not been adequately tested in previous phylogenetic studies, partly due to low taxonomic sampling density, but also to the use of few DNA markers. In this study, based on the 94 chloroplast genomes of sect.
