Stable interaction-induced Anderson-like localization embedded in standing waves

We uncover the interaction-induced \emph{stable self-localization} of bosons in disorder-free superlattices. In these nonthermalized multi-particle states, one of the particles forms a superposition of multiple standing waves, so that it provides a quasirandom potential to localize the other particles. We derive effective Hamiltonians for self-localized states and find their energy level spacings obeying the Poisson statistics for Anderson-like localization. Surprisingly, we find that the correlated self-localization can be solely induced by interaction in the well-studied nonintegrable Bose-Hubbard models, which has been overlooked for a long time. We propose a dynamical scheme to detect self-localization, where long-time quantum walks of a single particle form a superposition of multiple standing waves for trapping the subsequently loaded particles. Our work provides an experimentally feasible way to realize stable Anderson-like localization in translation-invariant disorder-free systems

mHealth in China and the United States: How Mobile Technology is Transforming Healthcare in the World's Two Largest Economies

In this paper, we explore ways mobile technology can help with these difficulties. Specifically, we look at avenues through which mobile devices boost productivity, aid communications, and help providers improve affordability, access, and treatment. Using data drawn from China and the United States as well as global trends, we look at recent developments andemerging opportunities in mobile health, or mHealth. We argue that mobile technology assists patients, health providers, and policymakers in several different respects. It helps patients by giving them tools to monitor their health conditions and communicate those results to physicians. It enables health providers to connect with colleagues and offers alternative sources of information for patients. It is also an important tool to inform policymakers on health delivery and medical outcomes

The Role of Malic Enzyme on Promoting Total Lipid and Fatty Acid Production in Phaeodactylum tricornutum

To verify the function of malic enzyme (ME1), the ME1 gene was endogenously overexpressed in Phaeodactylum tricornutum. Overexpression of ME1 increased neutral and total lipid content and significantly increased saturated fatty acids (SFAs) and polyunsaturated fatty acids (PUFAs) in transformants, which varied between 23.19 and 25.32% in SFAs and between 49.02 and 54.04% in PUFAs, respectively. Additionally, increased ME1 activity was accompanied by elevated NADPH content in all three transformants, indicating that increased ME1 activity produced additional NADPH comparing with that of WT. These results indicated that ME1 activity is NADP-dependent and plays an important role in the NADPH levels required for lipid synthesis and fatty acid desaturation in P. tricornutum. Furthermore, our findings suggested that overexpression of endogenous ME1 represents a valid method for boosting neutral-lipid yield in diatom

A new species of Boulenophrys from central Hunan Province, China (Anura: Megophryidae)

Abstract We re-examined the megophryinid population from Mt. Hengshan, Hunan Province, China previously identified as Boulenophrys brachykolos (under the name Megophrys brachykolos). Based on newly obtained molecular data, this population appears to be an independent lineage with a relatively distant phylogenetic relationship to B. brachykolos sensu stricto. Furthermore, this population exhibits distinct morphological characteristics that distinguish it from all its congeners. Therefore, we propose to recognize the Hengshan population of B. brachykolos as a new species, Boulenophrys hengshanensis sp. nov. described herein

Biocontrol and Plant Growth-Promoting Activity of Rhizobacteria From Chinese Fields With Contaminatd Soils

The aim of this study was to inventory the types of plant growth‐promoting rhizobacteria (PGPR) present in the rhizosphere of plants grown in soils contaminated with heavy metals, recalcitrant organics, petroleum sewage or salinity in China. We screened 1223 isolates for antifungal activity and about 24% inhibited Rhizoctonia solani or Sclerotinia sclerotiorum. Twenty‐four strains inhibitory to R. solani, Gaeumannomyces graminis var. tritici and/or S. sclerotiorum and representing the dominant morphotypes were assayed for PGPR activity. Seven strains contained phlD, prnD, pltC or phzF genes and produced the antibiotics 2,4‐diacetylphloroglucinol, pyrrolnitrin, pyoluteorin and phenazines respectively. Six strains contained acdS, which encodes 1‐aminocyclopropane‐1‐carboxylic acid deaminase. Phylogenetic analysis of 16S rDNA and phlD, phzF and acdS genes demonstrated that some strains identified as Pseudomonas were similar to model PGPR strains Pseudomonas protegens Pf‐5, Pseudomonas chlororaphis subsp. aureofaciens 30–84 and P. brassicacearum Q8r1‐96. Pseudomonas protegens‐ and P. chlororaphis‐like strains had the greatest biocontrol activity against Rhizoctonia root rot and take‐all of wheat. Pseudomonas protegens and P. brassicacearum‐like strains showed the greatest promotion of canola growth. Our results indicate that strains from contaminated soils are similar to well‐described PGPR found in agricultural soils worldwide

In the title complex, [Ag(C18H15P)3(ClO4)], the silver coord­ination environment is dominated by the distorted P3AgO tetra­hedron in which Ag—O = 2.608 (12) Å and the Ag—P bond lengths are 2.5663 (17), 2.5076(16) and 2.5450 (17) Å. The perchlorate O-atoms are disordered over two positions in a 0.584 (14):0.416 (14) ratio
