Ground state properties of heavy alkali halides
, 1998 We extend previous work on alkali halides by calculations for the heavy-atom species RbF, RbCl, LiBr, NaBr, KBr, RbBr, LiI, NaI, KI, and RbI. Relativistic effects are included by means of energy-consistent pseudopotentials, correlations are treated at ...

Rate of lineage origin explains the diversity anomaly in the World’s mangrove vegetation [PDF]
, 2006 The contribution of nonecological factors to global patterns in diversity is evident when species richness differs between regions with similar habitats and geographic area. Mangrove environments in the Eastern Hemisphere harbor six times as many species

River, EarlyView.Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

Molecular adaptation of rbcL in the heterophyllous aquatic plant Potamogeton. [PDF]
PLoS ONE, 2009 Heterophyllous aquatic plants show marked phenotypic plasticity. They adapt to environmental changes by producing different leaf types: submerged, floating and terrestrial leaves.

Rb4CuSb2X12 (X = Cl, Br) as Novel Vacancy‐Ordered Quadruple Perovskites
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.The vacancy‐ordered quadruple perovskites Rb4CuSb2X12 (X = Cl, Br) were crystallized from hydrohalic acid. Their crystal structures can be interpreted as new distortion variants of the perovskite structure with ordered vacancies. The electronic structure of Rb4CuSb2Br12 shows that the Br and Sb states form the valence band and the upper conduction band.

Phytochrome activates the plastid-encoded RNA polymerase for chloroplast biogenesis via nucleus-to-plastid signaling. [PDF]
, 2019 Light initiates chloroplast biogenesis by activating photosynthesis-associated genes encoded by not only the nuclear but also the plastidial genome, but how photoreceptors control plastidial gene expression remains enigmatic.

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)
Insect Science, EarlyView.As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Dating the cyanobacterial ancestor of the chloroplast [PDF]
, 2009 Cyanobacteria have played a pivotal role in the history of life on Earth being the first organism to carry out oxygenic photosynthesis, which changed atmospheric chemistry and allowed the evolution of Eukarya.
