Abstract

GaN nanowire ensembles with axial InGaN multi-quantum wells (MQWs) were grown by molecular beam epitaxy. In a series of samples, we varied the In content in the MQWs from almost zero to about 20%. Within the nanowire ensemble, the MQWs fluctuate strongly in composition and size. Statistical information about the composition was obtained from x-ray diffraction and Raman spectroscopy. Photoluminescence at room temperature was obtained in the range from 2.2 eV to 2.5 eV depending on In content. Contrary to planar MQWs, the intensity increases with increasing In content. We compare the observed emission energies with transition energies obtained from a one-dimensional model, and conclude that several mechanisms for carrier localization affect the luminescence of these three-dimensional structures., Comment: This is an author-created, un-copyedited version of an article accepted for publication in Nanotechnology.

Abstract

In recent years, there have been numerous studies from a variety of perspectives analyzing the Internet presence of hate and extremist groups. Yet the websites and forums of extremist and terrorist groups have long remained an underutilized resource for terrorism researchers due to their ephemeral nature and access and analysis problems. The purpose of the Dark Web archive is to provide a research infrastructure for use by social scientists, computer and information scientists, policy and security analysts, and others studying a wide range of social and organizational phenomena and computational problems. The Dark Web Forum Portal provides web enabled access to critical international jihadist and other extremist web forums. The focus of this paper is on the significant extensions to previous work including: increasing the scope of data collection, adding an incremental spidering component for regular data updates; enhancing the searching and browsing functions; enhancing multilingual machine-translation for Arabic, French, German and Russian; and advanced Social Network Analysis. A case study on identifying active participants is shown at the end.

Abstract

The strong spectral dependence of light absorption of brown carbon (BrC) aerosol is regarded to influence aerosol's radiative forcing significantly. The Absorption Angstrom Exponent (AAE) method was widely used in previous studies to attribute light absorption of BrC at shorter wavelengths for ambient aerosol, with a theoretical assumption that the AAE of "pure" black carbon (BC) aerosol equals to 1.0. In this study, the previous AAE method was improved by statistical analysis and applied in both urban and rural environments in the Pearl River Delta (PRD) region of China. A threewavelength photo-acoustic soot spectrometer (PASS-3) and aerosol mass spectrometers (AMS) were used to explore the relationship between the measured AAE and the relative abundance of organic aerosol to BC. The regression and extrapolation analysis revealed that the more realistic AAE values for "pure" BC aerosol were 0.86, 0.82, and 1.02 at 405 nm, and 0.70, 0.71, and 0.86 at 532 nm, in the campaigns of urban_winter, urban_fall, and rural_fall, respectively. Roadway tunnel experiments were also conducted, and the results further supported the representativeness of the obtained AAE values for "pure" BC aerosol in the urban environments. Finally, the average aerosol light absorption contribution of BrC was quantified to be 11.7, 6.3, and 12.1% (with relative uncertainties of 4, 4, and 7 %) at 405 nm, and 10.0, 4.1, and 5.5% (with relative uncertainties of 2, 2, and 5 %) at 532 nm, in the campaigns of urban_winter, urban_fall, and rural_fall, respectively. The relatively higher BrC absorption contribution at 405nm in the rural_fall campaign was likely a result of the biomass burning events nearby, which was supported by the biomass burning simulation experiments performed in this study. The results of this paper indicate that the brown carbon contribution to aerosol light absorption at shorter wavelengths is not negligible in the highly urbanized and industrialized PRD region.

Abstract

Aim. The purpose of this study is to investigate the effect of self-monitoring of blood glucose (SMBG) on glycemic control in insulin-naive type 2 diabetic patients comparing SMBG plus self-regulatory behavioral education, and SMBG plus individual education. Methods. Participants with glycated hemoglobin A1C (HbA1C) of 7.5-12% were enrolled in this 24-week, prospective study. Forty-two and forty participants received SMBG plus selfregulatory behavioral education, and SMBG plus individual education, respectively. The glycemic and behavioral attitudes outcomes were evaluated. Results. The A1C level decreased in both groups, from 9.41± 1.7% to 7.84± 0.83% in the SMBG plus self-regulatory behavioral education and 9.62 ±1.08% to 9.09± 1.1% in the SMBG plus individual education. However, the postprandial glucose (PPG) level sustained more significant decreases from 277.1 ±80.1 to 175.7 ±53.9 mg/dL in the SMBG plus self-regulatory behavioral education, and from 261.2 ±80.5 to 221.6 ±41.2 mg/dL in the SMBG plus individual education. The frequency of PPG monitoring increased from 0.1 ± 0.81 to 3.46 ± 2.81 times/week in SMBG plus self-regulatory behavioral education, whereas it increased from 0.13± 0.78 to 1.01± 0.89 in SMBG plus individual education. The amount of carbohydrates consumed per day decreased and the amount of physical activity performed per week increased significantly in self-regulatory behavioral education group. Conclusions. The use of this model of SMBG plus self-regulatory behavior education appears to have resulted in superior improvements in glycemic control and behavioral outcomes compared with those achieved by SMBG plus individual education.
