Luminescent point defect formation in 3C‐SiC by ion implantation

Optically active point defects in SiC are attracting a growing interest thanks to their prospect of emission in the near-infrared (NIR) spectral region (application in optical fiber communications and for in vivo imaging) and also thanks to the possibility to control optically their spin. Most of the results have been obtained for the hexagonal SiC polytypes. In this work, we focus on the optical properties of point defects in the 3C-SiC polytype after ion implantation. Different ions, fluences and post-implantation annealing were performed to optimize the defect formation. Photoluminescence results show that the optimal conditions for intense D1 defect related PL emission in the 600-850 nm range are high temperature annealing (up to 1200 °C) and a displacement density not exceeding 1020 cm-3 at the projected range. The creation of Ky5 defect at 1.12 eV has also been demonstrated for lower temperature annealing (800 °C). (© 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
1-Nitro-2-phenylethane dominates the chemical composition of the leaf essential oil of Uvaria chamae from Badagry, Nigeria

The leaf essential oil of Uvaria chamae (Annonaceae) was obtained by hydrodistillation and analyzed by GC-MS. A total of 69 compounds were identified in the leaf oil (99.6% of the composition), which was dominated by 1-nitro-2-phenylethane (63.2%), linalool (9.9%), and germacrene D (6.6%). The bioactivities of the major constituents account for the traditional uses of U. chamae leaves to treat fevers, wounds, swellings, and injuries.
Oxygen induced strong mobility modulation in few-layer black phosphorus

2D black phosphorus configured field-effect transistors generally show a hole-transport-dominated ambipolar characteristic, owing to the severely restricted electron mobility by air ambient. Here, we demonstrate the strongly modulated mobility of few-layer black phosphorus in contact with oxygen. Pure oxygen exposure can dramatically decrease the electron mobility of black phosphorus by over three orders of magnitudes without degrading the hole transport. In situ x-ray photoelectron spectroscopy characterization reveals the physisorption nature of oxygen on black phosphorus. Density functional theory calculations identify the unoccupied states of molecular oxygen physisorbed on few-layer black phosphorus, that serves as electron trap but not as hole trap, consistent with the aforementioned mobility modulation. In contrast, oxygen exposure upon light illumination exhibits a significant attenuation for both electron and hole transport, originating from the photoactivated oxidation of black phosphorus, as corroborated by in situ x-ray photoelectron spectroscopy measurements. Our findings clarify the predominant role of oxygen in modulating transport properties of black phosphorus, thereby providing deeper insight to the design of black phosphorus based complementary electronics.

Fighting Cancer with Phytochemicals from Allium Vegetables

Medicinal benefits of Allium are attributed to sulfur-containing compounds, collectively known as organosulfur compounds (OSCs), derived from garlic and other Allium vegetables. Most common OSCs are diallyl sulfide (DAS), diallyl disulfide (DADS), diallyl trisulfide (DATS) and ajoene. Epidemiological studies have suggested cancer risk reduction with increasing intake of Allium vegetables and this association has been documented for prostate, gastric, esophageal, breast and colorectal cancers. In vitro studies with different cancer cell lines, in vivo studies with chemically-induced carcinogenesis and tumor xenograft animal models proved that OSCs have chemopreventive as well as chemotherapeutic activity. DATS and other OSCs mediate their anticancer effects by altering the metabolism of carcinogens, by inhibiting cell cycle progression, inducing oxidative stress leading to DNA damage and consequently inducing apoptosis. Recent studies have found that these OSCs also possess anti-angiogenic activity. This review discusses the cancer chemopreventive and chemotherapeutic effects of DATS and other related OSCs from Allium vegetables in relevant models and its beneficial implications for humans.
Strengthening intermediaries in the National System of Innovation (NSI): Case of the South African Council for Natural Scientific Professions

This paper uses the National System of Innovation (NSI) framework to interrogate the role of professional organizations as intermediaries within the South African NSI. Using the case of the South African Council for Natural Scientific Professions (SACNASP), we explore the role of natural scientists within the country’s NSI ecosystem. Employing a survey of all natural science Voluntary Associations (VAs) affiliated with SACNASP, we highlight some successes that support the NSI, as well as current challenges and implications for the NSI. The study shows that while much has been achieved in skills development, more could be done to bolster the impact of SACNASP in the NSI. Findings suggest that collaborations and partnerships are distorted, with weak industry engagement. Ultimately, this paper argues for better governance and more effective engagement within VAs in order to address challenges of funding, skills development, knowledge production, and application.

Strontium ranelate-loaded PLGA porous microspheres enhancing the osteogenesis of MC3T3-E1 cells

Biodegradable poly lactic-co-glycolic acid (PLGA) has been used as a tissue engineering scaffold as well as a carrier for the delivery of proteins, drugs, and other macromolecules. Hydroxyapatite (HA) nanoparticle self-assembly on the surface of a PLGA microsphere can create a hydrophilic environment, and its hydroxide can neutralize the acidity of PLGA degradation products. These microspheres can be used to deliver strontium ranelate (SR), which is used to treat osteoporosis. In the present study, we fabricated porous PLGA microspheres (PM), SR-loaded (SR-)PM, and SR-PM with HA nanosuspension and polyvinyl alcohol (PVA) as a surfactant (SR-PM-HA) in a S/O/Ns method. The microspheres exhibited an interconnected porous structure. The percent cumulative release of SR from SR-PM was 90% in 22 days as compared to 85% from SR-PM-HA. In both cases, drug release was gradual (with no burst release). SR-PM and SR-PM-HA similarly stimulated the proliferation of MC3T3-E1 cells to a greater degree than PM and induced osteogenic differentiation, as determined by alkaline phosphatase staining and real-time PCR analysis of osteogenic marker gene expression. These results indicate that SR-PM-HA is biocompatible and suitable for drug delivery and osteoinduction.

Measuring shallow-water bathymetric signal strength in lidar point attribute data using machine learning

ABSTRACT The goal of this work was to evaluate if routinely collected but seldom used airborne lidar metadata – ‘point attribute data’ (PAD) – analyzed using machine learning/artificial intelligence can improve extraction of shallow-water (less than 20 m) bathymetry from lidar point clouds. Extreme gradient boosting (XGB) models relating PAD to an existing bathymetry/not bathymetry classification were fitted and evaluated for four areas near the Florida Keys. The PAD examined include ‘pulse specific’ information such as the return intensity and PAD describing flight path consistency. The R2 values for the XGB models were between 0.34 and 0.74. Global classification accuracies were above 80% although this reflected a sometimes extreme Bathy/NotBathy imbalance that inflated global accuracy. This imbalance was mitigated by employing a probability decision threshold (PDT) that equalizes the true positive (Bathy) and true negative (NotBathy) rates. It was concluded that 1) the strength of the bathymetric signal in the PAD should be sufficient to increase accuracy of density-based lidar point cloud bathymetry extraction methods and 2) ML can successfully model the relationship between the PAD and the Bathy/NotBathy classification. A method is also presented to examine the spatial and feature-space distribution of errors that will facilitate quality assurance and continuous improvement.
Robust Distribution System Load Restoration With Time-Dependent Cold Load Pickup

Service restoration is one of the critical functions to enable the future self-healing distribution system. To restore the distribution system in a timely and reliable manner, the realistic system operating conditions need to be accurately characterized. In this paper, two main factors that have great impacts on distribution system restoration (DSR) in practice are investigated. First, cold load pickup (CLPU), generally caused by thermostatically controlled loads (TCLs), is a common phenomenon after an outage and shaped by the outage duration. However, the time-dependent behaviors of CLPU are rarely considered in literature. In this paper, the operating state evolution of TCLs after an outage is analyzed to characterize time-dependent CLPU. And the time-dependent CLPU is analytically embedded in DSR to accurately represent the actual behaviors of the restored loads. Second, it is difficult to predict loads that fluctuate during DSR due to the lack of real-time measurement data. Accordingly, a robust DSR based on the information gap decision theory (IGDT) is proposed to address this challenge, fully considering the uncertainty of CLPU. The proposed models are tested in IEEE 13-node and 123-node test feeders. Simulation results demonstrate that the time-dependent CLPU model and the uncertainty modeling of CLPU can accurately capture the actual behaviors of loads with TCLs after an outage, which greatly improves DSR decisions in practice.
Synthesis, Characterization, and Photocatalytic Performance of ZnO–Graphene Nanocomposites: A Review

ZnO is an exciting material for photocatalysis applications due to its high activity, easy accessibility of raw materials, low production costs, and nontoxic. Several ZnO nano and microstructures can be obtained, such as nanoparticles, nanorods, micro flowers, microspheres, among others, depending on the preparation method and conditions. ZnO is a wide bandgap semiconductor presenting massive recombination of the generated charge carriers, limiting its photocatalytic efficiency and stability. It is common to mix it with metal, metal oxide, sulfides, polymers, and nanocarbon-based materials to improve its photocatalytic behavior. Therefore, ZnO–nanocarbon composites formation has been a viable alternative that leads to new, more active, and stable photocatalytic systems. Mainly, graphene is a well-known two-dimensional material, which could be an excellent candidate to hybridize with ZnO due to its excellent physical and chemical properties (e.g., high specific surface area, optical transmittance, and thermal conductivity, among others). This review analyses ZnO–graphene nanocomposites’ recent advances, addressing the synthesis methods and the resulting structural, morphological, optical, and electronic properties. Moreover, we examine the ZnO–graphene composites’ role in the photocatalytic degradation of organic/inorganic pollutants.
The Influence of Sustainable Earnings on Stock Price: Evidence from Publicly Listed Vietnamese Business Enterprises

Expected earnings and stock price are important determinants of investors’ decision. This research is conducted to estimate earnings persistence and examine the relationship between sustainable earnings on price-to-earning (P/E) ratio based on financial statements’ information of 631 publicly listed non-financial companies on Vietnam’s stock market, by using Ordinary Least Squares (OLS) and Logit function. The results show that earnings persistence depends on net operating assets growth, profit margin changes, operating asset turnover changes and past profitability. Besides, both the sustainable and unsustainable components of earnings growth are proved to empirically affect P/E ratio, even though investors underreact to sustainable earnings and overreact to unsustainable earnings. This study helps to improve investors’ perception of their future earnings, investment value and companies’ sustainable growth, particularly in the context of developing stock market of Vietnam which is full of market anomalies.
A Prospective Cohort Study providing Insights for Markers of Adverse Pregnancy Outcome in Women of Advanced Maternal Age

Background Advanced maternal age (AMA; ≥35 years) is associated with increased rates of adverse pregnancy outcome. Better understanding of underlying pathophysiological processes may improve identification of AMA mothers who are at greatest risk of adverse outcome. This study aimed to investigate changes in oxidative stress and inflammation in AMA women and identify clinical and biochemical predictors of adverse pregnancy outcome in women of AMA.Methods The Manchester Advanced Maternal Age Study (MAMAS) was a multicentre, observational, prospective cohort study of 527 mothers. Participants were divided into three age groups for comparison 20-30 years (n=158), 35-39 years (n=212) and ≥40 years (n=157). Demographic and medical data were collected along with maternal blood samples at 28 and 36 weeks’ gestation. Multivariable analysis was conducted to identify variables associated with adverse outcome, defined as one or more of: small for gestational age (<10th centile), FGR (<5th centile), stillbirth, NICU admission, preterm birth <37 weeks gestation or Apgar score <7 at 5 minutes. Biomarkers of inflammation, oxidative stress and placental dysfunction were quantified in maternal serum. Univariate and multivariable statistical analyses were used to identify associations with composite adverse fetal outcome.Results: Maternal smoking was associated with adverse outcome in older mothers (Adjusted Odds Ratio (AOR) 4.34, 95% Confidence Interval (95%CI) 1.88, 9.99), whereas multiparity reduced the odds (AOR 0.56, 95% CI 0.34, 0.99). In uncomplicated AMA pregnancies, lower circulating anti-inflammatory IL-10, IL-RA and increased antioxidant capacity (TAC) were seen. In AMA with adverse outcome, TAC and oxidative stress markers were increased and levels of maternal circulating placental hormones (hPL, PlGF and sFlt-1) were reduced (p<0.05). Of these, placental growth factor had the strongest predictive accuracy (Area Under the Receiver Operator Characteristic (AUROC) = 0.74) followed by TAC (AUROC=0.69). Conclusions: This study identified alterations in circulating inflammatory and oxidative stress markers in AMA women and in AMA women with adverse pregnancy outcome providing preliminary evidence of mechanistic links. Further, larger studies are required to determine if these markers can be developed into a predictive model of an individual AMA woman’s risk of APO, enabling a reduction in stillbirth rates whilst minimising unnecessary intervention.
Akhlak and Academic Ethics: Idealism Among Pragmatism in Community Social Life

Basically, in social life in achieving progress it is indicated that a person is able to meet the needs of a social group so that that person can contribute to society. Regardless of the intention of a person, one of the efforts made by the community to obtain education is to get a scholarship so that it gets recognition from the community about their social status. If we look at it in today's society, it seems that this view has started to shift because if we see that the award is more to a degree than from one's knowledge. This has prompted some people to take academic degrees with a path that is not in accordance with the procedure. The procedure that was followed was what damaged the social order and academic ethics. It can be said that this degree was obtained based on the objective, namely degree fever. The academic world is a forum whose process always follows academic ethics through scientific activities. Thus academic ethics is essentially a scientific activity that takes place in higher education which includes universal and developing activities. Higher education institutions must be prepared to accept criticism with mutual respect and not engage in discriminatory activities. Violations committed in academic ethics are something that damages and tarnishes the world of education. In order for these educational values to be implemented optimally, we need a rule that can control the process of implementing education; this is what is called academic ethics. The emphasis on the value of honesty in academic ethics consists of two things, namely in writing scientific papers and completing studies. Therefore, it is demanded that every education actor is systematic and comprehensive and requires commitment from various parties to fix problems in education.

Iki porlu potasyum kanallari, biyolo-jik membranlarda bulunan protein kompleksleridir. Iki porlu potas-yum kanallari, potasyum iyonlari icin ozeldir ve potasyumun hucre membranindan gecmesine izin verirler. Iki porlu potasyum kanal-lari, noronal uyarilma, norotransmitter ve hormon salinimi yoluyla, membran potansiyelindeki degisikliklerden de sorumludurlar. Iki porlu potasyum kanallarin TASK-1 ve TREK-1 alt tipleri volatil anes-tezik ajanlarla (ornegin, izofluran, kloroform, dietil eter) uyarilir. Bu makalede santral sinir sisteminde bulunan ve genel anesteziklerin etkisinden sorumlu reseptorler ve bunlarin etki mekanizmalari gozden gecirilecektir.
