Study of color-octet matrix elements through \(J/\psi \) production in \(e^{+}e^{-}\) annihilation

In this paper, the color-octet long distance matrix elements are studied through the inclusive \(J/\psi \) production in \(e^{+}e^{-}\) annihilation within the framework of non-relativistic QCD factorization. The calculations are up-to next-to-leading order with the radiative and relativistic corrections in the energy region of the B-factory and the near-threshold region of ...

China’s engagement with development assistance for health in Africa

Background As an emerging donor in health related development across the world, particularly towards Africa, the People’s Republic of China (PRC) has been increasing its influence within the field of global public health over the past few decades. Yet between the period of 2000 and 2013, little is known about the scope, scale and priority of China’s grant-making programs. Methods ...

Heuristic Strategies for Persuader Selection in Contagions on Complex Networks

Individual decision to accept a new idea or product is often driven by both self-adoption and others’ persuasion, which has been simulated using a double threshold model [Huang et al., Scientific Reports 6, 23766 (2016)]. We extend the study to consider the case with limited persuasion. That is, a set of individuals is chosen from the population to be equipped with persuasion ...

Total arsenic and speciation analysis of saliva and urine samples from individuals living in a chronic arsenicosis area in China

Background It is generally acknowledged that the determination of harmful chemical compounds excreted into saliva is useful for assessing their exposure levels. The aim of the present study was to compare the total arsenic and its species in saliva and urine samples collected from the people residing in an arsenic-contaminated area of China and to further verify the feasibility of ...

SDF-1/CXCR7 axis regulates the proliferation, invasion, adhesion, and angiogenesis of gastric cancer cells

Background More recent studies have revealed that chemokine receptor CXCR7 plays an important role in cancer development. However, little is known about the effect of CXCR7 on the process of gastric cancer cell invasion and angiogenesis. The aim of this study is to investigate the expression of CXCR7 in gastric cancer cell lines and to evaluate the role of CXCR7 in the ...

Thermally stable polymer–ceramic composites for microwave antenna applications

Polymer–ceramic composites were prepared by twin screw melt extrusion with high-density polyethylene (HDPE) as the matrix and polystyrene-coated BaO–Nd2O3–TiO2 (BNT) ceramics as the filling material. Interestingly, the incorporation of polystyrene (PS) by the coating route could significantly improve the thermal behaviors of the composites (HDPE–PS/BNT), besides the temperature ...

MoS2 with tunable surface structure directed by thiophene adsorption toward HDS and HER

MoS2 catalysts with more active sites and larger surface areas were successfully synthesized via a simple hydrothermal reaction method, and the surface structure of MoS2 was readily tailored by simply adding thiophene during the synthesis procedure. The MoS2 samples synthesized with thiophene, especially MoS2 prepared with 200 μL of thiophene, concomitantly exhibited better ...

A Gene-Oriented Haplotype Comparison Reveals Recently Selected Genomic Regions in Temperate and Tropical Maize Germplasm

The extensive genetic variation present in maize (Zea mays) germplasm makes it possible to detect signatures of positive artificial selection that occurred during temperate and tropical maize improvement. Here we report an analysis of 532,815 polymorphisms from a maize association panel consisting of 368 diverse temperate and tropical inbred lines. We developed a gene-oriented ...

HNRNPA2B1 regulates the epithelial–mesenchymal transition in pancreatic cancer cells through the ERK/snail signalling pathway

Background Heterogeneous nuclear ribonucleoprotein A2B1 (HNRNPA2B1) is closely related to tumour occurrence and development, oncogene expression, apoptosis inhibition and invasion and metastasis capacities. However, its function in the epithelial–mesenchymal transition (EMT) of pancreatic cancer is not fully understood. Methods By comparing various wild-type pancreatic cancer cell ...

\(B^*_{s,d} \rightarrow \mu ^+ \mu ^-\) and its impact on \(B_{s,d} \rightarrow \mu ^+ \mu ^-\)

This study investigates \(B^*_{s,d}\rightarrow \mu ^+\mu ^-\) in the dimuon distributions and the hadronic contribution \(B_{s,d}\rightarrow B^*_{s,d}\gamma \rightarrow \mu ^+\mu ^-\). The \(\mu ^+\mu ^-\) decay widths of the vector mesons \(B^*_{s,d}\) are approximately a factor of 700 larger than the corresponding scalar mesons \(B_{s,d}\). The ratio of the branching fractions ...

miR-24-3p Suppresses Malignant Behavior of Lacrimal Adenoid Cystic Carcinoma by Targeting PRKCH to Regulate p53/p21 Pathway

MicroRNA (miRNA) may function as an oncogene or a tumor suppressor in tumorigenesis. However, the mechanism of miRNAs in adenoid cystic carcinoma (ACC) is unclear. Here, we provide evidence that miR-24-3p was downreglated and functions as a tumor suppressor in human lacrimal adenoid cystic carcinoma by suppressing proliferation and migration/invasion while promoting apoptosis. ...

An Apple Fruit Fermentation (AFF) Treatment Improves the Composition of the Rhizosphere Microbial Community and Growth of Strawberry (Fragaria × ananassa Duch ‘Benihoppe’) Seedlings

Plant growth can be promoted by the application of apple fruit fermentation (AFF), despite unclear of the underlying mechanisms, the effects involved in AFF on rhizosphere microorganisms have been hypothesized. We investigated the consequences of applying AFF alone or in combination with Bacillus licheniformis to strawberry tissue culture seedlings in vitro, the analyses of ...

The Effect of Iron Fortification on Iron (Fe) Status and Inflammation: A Randomized Controlled Trial

Background Iron deficiency (ID) is common in toddlers in developing countries. Iron fortified or meat-based complementary foods may be effective to prevent ID. Objective Our objective was to compare iron status at 18 months and growth from 6 to 18 months in rural poor toddlers fed 3 different complementary foods. Methods The study was nested within a larger trial in which ...

Location and moment tensor inversion of small earthquakes using 3D Green’s functions in models with rugged topography: application to the Longmenshan fault zone

With dense seismic arrays and advanced imaging methods, regional three-dimensional (3D) Earth models have become more accurate. It is now increasingly feasible and advantageous to use a 3D Earth model to better locate earthquakes and invert their source mechanisms by fitting synthetics to observed waveforms. In this study, we develop an approach to determine both the earthquake ...
