Effective model and electron correlations in trilayer nickelate superconductor LaNiO.

Recently, signatures of superconductivity with critical temperature from 20 to 30 K have been reported in pressured trilayer nickelate LaNiOthrough a pressure-induced structure transition. Here we explore the evolution of electronic structures and electronic correlations in different phases of LaNiOunder corresponding pressure regions, by using density functional theory (DFT) combined with dynamical mean-field theory (DMFT). Similar to bilayer superconductor LaNiO, the electronic bands in superconducting LaNiOare dominated by Ni-3dx2-y2and 3dz2orbits near the Fermi level, in contrast, the inner Ni-O plane in LaNiOgenerates a doublet hole-pocket Fermi surfaces around the Brillouin-zone corner, meanwhile one branch of the Ni-3dz2bands is pushed very close above the Fermi level, which can induce an electron pocket through small electron doping.

Population dynamics and seasonal migration patterns of in northern China based on 11 years of monitoring data.

Background: The beet armyworm, (Hübner), is an important agricultural pest worldwide that has caused serious economic losses in the main crop-producing areas of China. To effectively monitor and control this pest, it is crucial to investigate its population dynamics and seasonal migration patterns in northern China.

Methods: In this study, we monitored the population dynamics of using sex pheromone traps in Shenyang, Liaoning Province from 2012 to 2022, combining these data with amigration trajectory simulation approach and synoptic weather analysis.

Analysis of the Development Trend in Forensic Odontology Based on CiteSpace.

Objectives: To realize the dynamic visualization of forensic odontology based on the bibliometrics methods, and capture the research hotspots and identify the future development trend.

Methods: Literature articles published from January 1995 to December 2020 were searched according to specific subject words in the core data set of Web of Science. The visualization analysis of publishing country, institution, discipline, author, co-cited journal and keywords was performed by CiteSpace 5.

Research trend of microbiota-gut-brain axis in Alzheimer's disease based on CiteSpace (2012-2021): A bibliometrics analysis of 608 articles.

Background: Recently, research on the microbiota-gut-brain axis (MGBA) has received increasing attention, and the number of studies related to Alzheimer's disease (AD) has increased rapidly, but there is currently a lack of summary of MGBA in AD.

Objective: To capture research hotspots, grasp the context of disciplinary research, and explore future research development directions.

Methods: In the core dataset of Web of Science, documents are searched according to specific subject words.

Network reconstruction of social networks based on the public information.

The structure of a social network plays a crucial role for dynamic analysis, which is invisible in most scenes. In this paper, we present a model for reconstructing the social network by taking into account the public opinion diffusion dynamic model for specific agenda. First, the initial polarity attitude of users i for the agenda, o, is set in the range [-1,1], where negative and positive attitudes are set as -1 and 1, respectively, while 0 means that user i's attitude is uncertain.

[Symbiotic bacteria facilitate algal growth and oil biosynthesis in Scenedesmus obliquus].

We isolated bacteria from the phycosphere of Scenedesmus obliques and sequenced 16S rDNAs to establish algae-bacterial co-culture systems. Further, we examined effects of the bacteria on algal growth, and parameters associated with physio-biochemical and oil-producing characteristics of S. obliquus.

On-demand one-step synthesis of small-sized fluorescent-magnetic bifunctional microparticles on a droplet-splitting chip.

A facile and controllable method for one-step synthesis of small-sized monodisperse fluorescent-magnetic bifunctional microparticles based on droplet splitting and photopolymerization was established. Using this method, magnetic nanoparticles and acryloyl rhodamine B (acryloyl-RhB) molecules were incorporated into the dispersed phase, which allowed the direct generation of functional microparticles. Functional microparticles with diameters in the range of 2.

Controllable synthesis of nanocrystals in droplet reactors.

In recent years, a broad range of nanocrystals have been synthesized in droplet-based microfluidic reactors which provide obvious advantages, such as accurate manipulation, better reproducibility and reliable automation. In this review, we initially introduce general concepts of droplet reactors followed by discussions of their main functional regions including droplet generation, mixing of reactants, reaction controlling, in situ monitoring, and reaction quenching. Subsequently, the enhanced mass and heat transport properties are discussed.
