（N, F）-codoped anatase TiO2 nanocrystals with active visible light response were prepared by using a simple sol-gel approach. X-ray photoelectron spectroscopy measurements suggested that the substitutional N and F species replaced the lattice oxygen atoms in TiO2 nanocrystals. Such nanocrystals showed strong absorption from 400 to 550 nm, which was mainly induced by nitrogen doping. The phase transformation from anatase to rutile was hindered by fluorine doping at high calcination temperatures, which was verified by XRD patterns. The N2 adsorption-desorption isotherms revealed the absence of mesopores in these nanocrystals. The （N, F）- codoped TiO2 nanocrystals showed satisfying photocatalytic activity on the photo-degradation of methylene blue under visible light.

Toxic effect of lead(Pb) pollution on Collembola in soils has seldom been studied in depth, which is especially true for growth responses since the juveniles are very small and numerous. A single species test was conducted using the collembolan Folsomia candida as the indicator species, and soil Pb pollution(at Pb concentrations of 0, 300, 600, 1 200, 2 400, and 4 800 mg kg^(-1)) was simulated by mixing Pb(NO_(3))_(2) with a natural unpolluted soil. Adult survival, reproduction, body length, and body Pb concentration were determined. Adult survival and reproduction started to decrease at soil Pb concentrations of 1 200 and 600 mg kg^(-1), respectively. Lead concentrations in adult and juvenile bodies increased with increasing Pb concentration in soil. The percentage and individual abundances based on body length analysis showed that the larger adults(2.1–2.6 mm, P < 0.01) were more sensitive to soil Pb concentration than the intermediate(1.9–2.1 mm, P < 0.001) and smaller(1.7–1.9 mm, P < 0.001) adults. Similarly, the larger juveniles(1.0–1.4 mm, P < 0.001) were more sensitive to soil Pb concentration than the intermediate(0.6–1.0 mm, P < 0.001) and smaller(0.3–0.6 mm, P < 0.001) juveniles. For both adults or juveniles, the abundance and percentage of larger individuals declined significantly with increasing soil Pb concentration, suggesting that larger individuals were more sensitive to soil Pb pollution. Therefore, body length features, especially the percentage and abundance of larger individuals, would be potential bio-indicators of soil Pb pollution and possibly other types of soil pollution.

In the current data-intensive era, the traditional hands-on method of conducting scientific research by exploring related publications to generate a testable hypothesis is well on its way of becoming obsolete within just a year or two. Analyzing the literature and data to automatically generate a hypothesis might become the de facto approach to inform the core research efforts of those trying to master the exponentially rapid expansion of publications and datasets. Here, viewpoints are provided and discussed to help the understanding of challenges of data-driven discovery.

Purpose： This paper aims to better understand a large number of papers in the medical domain of Alzheimer＇s disease （AD） and related diseases using the machine reading approach. Design/methodology/approach： The study uses the topic modeling method to obtain an overview of the field, and employs open information extraction to further comprehend the field at a specific fact level. Findings： Several topics within the AD research field are identified, such as the Human Immunodeficiency Virus （HIV）/Acquired Immune Deficiency Syndrome （AIDS）, which can help answer the question of how A1DS/HIV and AD are very different yet related diseases. Research limitations： Some manual data cleaning could improve the study, such as removing incorrect facts found by open information extraction. Practical implications： This study uses the literature to answer specific questions on a scientific domain, which can help domain experts find interesting and meaningful relations among entities in a similar manner, such as to discover relations between AD and AIDS/HIV. Origlnality/value： Both the overview and specific information from the literature are obtained using two distinct methods in a complementary manner. This combination is novel because previous work has only focused on one of them, and thus provides a better way to understand an important scientific field using data-driven methods.

According to the construction of current coal mine monitoring and control systems in China, the paper proposes three kinds of applicable schemes of integrating PLC and DCS systems with field bus technology to digitize the system and to improve the flexibility and extent of the system. Essentially, the paper introduces the integration of FCS on I/O layers. Based on a real coal mine safety-monitoring and control system applied with a CAN field bus, the major technology of system relays and extensions is discussed. We believe that one of the most applicable methods is currently replacing the connection between function-stations and field-sensors with a CAN bus on I/0 layers for system integration.

AIM： To investigate the association between ocular demodex folliculorum infestation and ocular surface manifestations in meibomian gland dysfunction（MGD）.METHODS： Eight-six patients with MGD were enrolled. All enrolled subjects were tested in the following sequence： ocular surface disease index（OSDI）, slit-lamp biomicroscope examination, corneal surface regularity index（SRI） and surface asymmetry index（SAI）, tear fluid collection, fluorescein tear film break-up time（F-BUT）, corneal fluorescein staining（CFS）, Schirmer I test（SIT） and demodex folliculorum counting. Tear matrix metalloproteinase（MMP）-9 activity was assessed using MMP-9 activity assay ***： Among 86 MGD patients, 40 were positive for demodex. The ocular demodex-positive group showed significantly increased scores of OSDI（25.96±13.74 vs 18.07±11.55, P=0.01）, lid margin abnormality（2.38±0.87 vs 1.98±0.91, P=0.04） and CFS（1.28±2.00 vs 0.94±1.36, P=0.01） compared to the ocular demodex-free group. The tear MMP-9 activity was higher in the ocular demodex-positive group（102.9±32.4 ng/mL） than the ocular demodex-free group（46.2±19.2 ng/mL, P=0.03）. There was no significant difference in meibum quality and expressibility, SRI, SAI, F-BUT and SIT between the two groups（P〉0.05 for each）. No significant correlation was noted between the number of demodex and ocular surface parameters in demodexpositive MGD group（P〉0.05 for each）.CONCLUSION： Ocular demodex folliculorum infestation may be associated with ocular discomfort and ocular surface damage in MGD.
