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 ...

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 ...

Facility location with double-peaked preferences

sufficiently close for the school to be easily accessible by the Aris Filos-Ratsikas and Jie Zhang were supported by the ERC Advanced Grant 321171 (ALGAME) and the Sino-Danish Center for the Theory of

Modelling of a post-combustion CO2 capture process using extreme learning machine

% reduction of CO2 emission by 2050 comparing with the & Jie Zhang level in 1950 is set by the Intergovernmental Panel on Climate Change. Carbon capture and storage (CCS) has been widely believed as an

P-mTOR Expression and Implication in Breast Carcinoma: A Systematic Review and Meta-Analysis

Objective Phosphorylated mammalian target of rapamycin (p-mTOR) is a promising prognostic marker in many types of cancer. However, its survival benefit in patients with breast carcinoma remains unknown. The aim of the present study was to assess the relationship between p-mTOR expression and prognosis in breast carcinoma based on a systematic review and meta-analysis. Materials and ...

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 ...

Changes in event-related potentials in patients with first-episode schizophrenia and their siblings

Background This study aimed to explore the characteristics of event-related potentials induced by facial emotion recognition in patients with first-episode schizophrenia and in their siblings. Methods In this case-control study, 30 first-episode schizophrenia patients, 26 siblings, and 30 healthy controls were enrolled. They completed facial emotion recognition tasks from the Ekman ...

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 ...

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 ...

Casticin induces apoptosis and G0/G1 cell cycle arrest in gallbladder cancer cells

Background Casticin, the flavonoid extracted from Vitex rotundifolia L, exerts various biological effects, including anti-inflammatory and anti-cancer activity. The aim of this study is to investigate the effects and mechanisms of casticin in human gallbladder cancer cells. Methods Human NOZ and SGC996 cells were used to perform the experiments. CCK-8 assay and colony formation ...

Effect of Base Oil Structure on Elastohydrodynamic Friction

The EHD friction properties of a wide range of base fluids have been measured and compared in mixed sliding–rolling conditions at three temperatures and two pressures. The use of tungsten carbide ball and disc specimens enabled high mean contact pressures of 1.5 and 2.0 GPa to be obtained, comparable to those present in many rolling bearings. The measurements confirm the importance ...

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 ...

High platelet reactivity affects the clinical outcomes of patients undergoing percutaneous coronary intervention

Background The association of platelet reactivity and clinical outcomes, especially stent thrombosis, was not so clear. We sought to investigate whether high platelet reactivity affects clinical outcomes of patients with drug eluting stents (DESs) implantation. Methods All enrolled individuals treated with DESs implantation were evaluated by PL-11, using sequentially platelet ...

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 ...
