为了研究木质部细胞、树木个体和森林群落3个尺度之间的关联,在西伯利亚南部以西伯利亚落叶松(Larix sibirica)和欧洲赤松(Pinus sylvestris)为主的3个采样点37个样地,测量725根树芯的树木年轮宽度,采用系统随机的方法选择其中195个树芯进行管胞大小的测量和计算。结果表明,尽管局地环境和树种组成有所不同,但在树木个体和森林群落两个水平上,管胞大小与树木径向生长的年际变化显著相关。较小的平均管胞尺寸指示更低的年际生长量和更高的年际生长波动。平均管胞大小对半干旱区针叶林生境湿度和森林生长适应性具有指示作用,揭示树木通过调节管胞的大小在生长适应与生长安全性二者间的权衡机制。

Dear Editor,Spatial transcriptomics(ST)makes it possible to perform RNA-seq at hundreds of precisely located spots on the surface of a histological slice(Stahl et al.,2016).Since mRNA diffusion is minimal during tissues permeabilization and mRNA capture,the transcriptome of each spot is thought to aggregate the transcriptomes of the cells it contains.

Direct integration of high-mobility III-v compound semiconductors with existing Si-based complementary metal-oxide-semiconductor （CMOS） processing platforms presents the main challenge to increasing the CMOS performance and the scaling trend. Silicon hetero-nanowires with integrated III-v segments are one of the most promising candidates for advanced nano-optoelectronics, as first demonstrated using molecular beam epitaxy techniques. Here we demonstrate a novel route for InAs/Si hybrid nanowire fabrication via millisecond range liquid-phase epitaxy regrowth using sequential ion beam implantation and flash-lamp annealing. We show that such highly mismatched systems can be monolithically integrated within a single nanowire. Optical and microstructural investigations confirm the high quality hetero-nanowire fabrication coupled with the formation of atomically sharp interfaces between Si and InAs segments. Such hybrid systems open new routes for future high-speed and multifunctional nanoelectronic devices on a single chip.

The Yellow-legged hornet, vespa velutina , was accidentally introduced in France in 2004, and then spread rapidly through the French territory but also to adjacent European countries (Spain, Portugal, and Belgium). During summer and autumn, v. velutina workers hunt domestic honeybees, Apis mellifera, for feeding their larvae. The impact of this alien species is mainly economic, beekeepers experiencing heavy colony losses, but also ecological, v. velutina hunting other pollinators. In their year-round life cycle, nest initiation by single queen during spring is the critical stage. In invaded areas, spring queen trapping using food baits has been promoted by apicultural unions in order to limit v. velutina population expansion. The goals of this work were 1) to evaluate the yield of this method, 2) to identify appropriate sites for trapping, 3) to identify potential optimal climatic windows of capture, and 4) to quantify the impact on local entomofauna. Our results showed that water proximity enhances trapping but not beehives proximity, and that trapping is inefficient if average week temperatures are below 10°C. Although the trapping effect on biodiversity should be studied more carefully, spring queen trapping is highly questionable unless specific attractants could be proposed.

Transition metal oxides with 4d or 5d metals are of great interest due to the competing interactions, of the Coulomb repulsion and the itineracy of the d-electrons, opening a possibility of building new quantum ground states. Particularly the 5d metal oxides containing Iridium have received significant attention within the last years, due to their unexpected physical properties, caused by a strong spin orbit coupling observed in It（Iv）. A prominent example is the Mott-insulator Sr2IrO4. Another member of this family, the honeycomb lattice compound Na2IrO3, also being a Mott-insulator having, most probably, a Kitaev spin liquid ground state. By deintercalating sodium from Na2IrO3, the authors were able to synthesize a new honeycomb lattice compound with more than 50% reduced sodium content. The reduction of the sodium content in this layered compound leads to a change of the oxidation state of iridium from ＋ Iv to ＋ v/＋ vI and a symmetry change from C2/c to P-3. This goes along with significant changes of the physical properties. Besides the vanishing magnetic ordering at 15 K, also the transport properties changes and instead insulating semiconducting properties are observed.

Tricin (and tricin containing plant extracts) has been shown to exert a pronounced antiviral activity, high radical scavenging activity and is favored for its safety profile. In the present study we have analyzed the pharmacokinetics of tricin after a single intravenous and oral administration to Wistar rats of an ethanol extract of Calamagrostis Adans and Deschampsia Beauv plants (test agent) at different doses. Tricin concentrations in blood plasma and blood cells were measured at different time points. Two-compartment (for intravenous injection) and one compartment (for oral administration) models were used for the analysis of tricin pharmacokinetics. The results showed that the pharmacokinetics of tricin after intravenous injection of test agent has a pronounced biphasic character, is well described by a two-compartment pharmacokinetic model, and is characterized by non-linear dose-dependence. The pharmacokinetics of tricin administered orally is characterized by a high rate of absorption from the gastrointestinal tract into the blood and rather slow elimination, which leads to a large volume of distribution in the body and a fairly high bioavailability. The obtained results indicate the advantages of the oral route of administration over the intravenous route.
