Nuclear Genome Size is Positively Correlated with Median LTR-RT Insertion Time in Fern and Lycophyte Genomes

open access: yesAmerican Fern Journal, 2019
. Nuclear genome size is highly variable in vascular plants. The composition of long terminal repeat retrotransposons (LTR-RTs) is a chief mechanism of long term change in the amount of nuclear DNA. Compared to flowering plants, little is known about LTR-

Nutzen der 3d‐4f Koordination: Molekulares Quanten‐Feder‐Magnet‐Verhalten in axialen Ni2Ln Komplexen

open access: yesAngewandte Chemie, EarlyView.
Wir berichten über heterotrimetallische Ni2Ln Komplexe, die Austauschfeder‐Magnete auf molekularer Ebene nachahmen. CASSCF Rechnungen zeigen kollineare Anisotropieachsen, während µSQUID Studien langsame Relaxation und offene Hysterese in Ni2Tb, Ni2Dy, und Ni2Ho offenbaren.

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Unveiling Morphine: A Rapid and Selective Fluorescence Sensor for Forensic and Medical Analysis

open access: yesSensors
Opioid use, particularly morphine, is linked to CNS-related disorders, comorbidities, and premature death. Morphine, a widely abused opioid, poses a significant global health threat and serves as a key metabolite in various opioids.

Mechanical male sterilisation in invasive signal crayfish Pacifastacus leniusculus: persistence and functionality in captive and wild conditions

open access: yesKnowledge and Management of Aquatic Ecosystems, 2022
Management control methods for invasive crayfish remain of limited effectiveness, resulting in ongoing invasions of high ecological impact. As management programmes integrating methods to limit juvenile recruitment could reduce population abundances, the

Order-level fern plastome phylogenomics: new insights from Hymenophyllales.

open access: yesAmerican-Eurasian journal of botany, 2018
PREMISE OF THE STUDY Filmy ferns (Hymenophyllales) are a highly specialized lineage, having mesophyll one-cell layer thick and inhabiting particularly shaded and humid environments. The phylogenetic placement of Hymenophyllales has been inconclusive, and

Morphometric analysis of postnatal lung development in the gray short‐tailed opossum (Monodelphis domestica): An ultrastructural study

open access: yesThe Anatomical Record, EarlyView.
Abstract An ultrastructural morphometric analysis of the postnatal development of the lung in the gray short‐tailed opossum (Monodelphis domestica) has been conducted to evaluate the morphofunctional status of this poorly developed marsupial lung immediately following parturition.

Point'n Move: Interactive scene object manipulation on Gaussian splatting radiance fields

open access: yesIET Image Processing
The authors propose Point'n Move, a method that achieves interactive scene object manipulation with exposed region inpainting. Interactivity here further comes from intuitive object selection and real‐time editing.
