Over a Decade of Social Opinion Mining

Social media popularity and importance is on the increase, due to people using it for various types of social interaction across multiple channels. This social interaction by online users includes submission of feedback, opinions and recommendations about various individuals, entities, topics, and events. This systematic review focuses on the evolving research area of Social Opinion Mining, tasked with the identification of multiple opinion dimensions, such as subjectivity, sentiment polarity, emotion, affect, sarcasm and irony, from user-generated content represented across multiple social media platforms and in various media formats, like text, image, video and audio. Therefore, through Social Opinion Mining, natural language can be understood in terms of the different opinion dimensions, as expressed by humans. This contributes towards the evolution of Artificial Intelligence, which in turn helps the advancement of several real-world use cases, such as customer service and decision making. A thorough systematic review was carried out on Social Opinion Mining research which totals 485 studies and spans a period of twelve years between 2007 and 2018. The in-depth analysis focuses on the social media platforms, techniques, social datasets, language, modality, tools and technologies, natural language processing tasks and other aspects derived from the published studies. Such multi-source information fusion plays a fundamental role in mining of people's social opinions from social media platforms. These can be utilised in many application areas, ranging from marketing, advertising and sales for product/service management, and in multiple domains and industries, such as politics, technology, finance, healthcare, sports and government. Future research directions are presented, whereas further research and development has the potential of leaving a wider academic and societal impact.
Modeling exothermic heat generation during the roasting of coffee.

Exothermic heat generation during coffee roasting was modeled as a single, first-order reaction with a rate coefficient governed by the Arrhenius equation. With best-fit values for parameters, E and Aq, heat-generation rates calculated with the resulting equation, Eq [2], agreed fairly well with rates measured by DSC by Raemy (1981). Improved agreement with Raemy’s rate data was obtained by similarly modeling four parallel reactions, i.e. by using Eq [6]. Results calculated with Eq [6] for typical temperature versus time behavior for roasting bean show that the exothermic reactions producing the most heat are far from complete at the end of normal roasting; but others with higher E and/or Aq essentially go to completion. Raemy’s DSC test method prevented evaporative cooling from partially cancelling exothermic heating, but probably also created an abnormal reaction environment. DSC tests carried out with suitably predried coffee beans should provide a more normal environment and provide data permitting better modeling.
Le concept d’indice de fibrosité des aliments des ruminants

connue depuis longtemps en raison de ses implications pathologiques et zootechniques. L’évolution de l’élevage, des vaches laitières en particulier, se traduit par une préoccupation de plus en plus fréquente de la fibrosité des rations bien qu’aucune mesure objective et standardisée n’existe pour la caractériser. Dans ce contexte, il a paru utile de faire le point de la connaissance sur le concept de fibrosité et des conséquences pratiques à en tirer.

Influence of SO2 on Nucleation, Growth Rates and Yield of Secondary Organic Aerosol (SOA)

Binary nucleation of sulphuric acid and water was observed to occur in laboratory experiments at atmospherically relevant concentrations (Berndt et al.; 2005). In addition, laboratory experiments show that the nucleation of sulphuric acid is considerably enhanced in the presence of organic acids due to the formation of a stable aromatic acid-sulphuric acid complex, which reduces the nucleation barrier (Zhang et al.; 2004). Several laboratory studies have examined the role of acidic aerosols in enhancing the uptake of carbonyl compounds through acid catalyzed reactions (Jang et al.; 2003) and the influence on the SOA yield (Kleindienst et al.; 2006). A laboratory study was carried out to investigate the secondary organic aerosol formation of 1,3,5-trimethylbenzene (TMB) in the presence of SO2. Several experiments were carried out using SO2 concentrations between 0.2 and 20 ppb for TMB concentrations of 150, 300, 600 and 1200 ppb, while keeping all the other parameters constant. Aerosol size distributions were measured using a twin SMPS system. The first is a nano SMPS composed of a short DMA column and a TSI UWCPC, while the second one consisted of a long DMA column and a TSI 3022CPC. This combination of instruments provided measurements of the size distributions over the size range from 4 to 700 nm diameter. VOC concentrations were measured using a Proton Transfer Reaction-Mass Spectrometer (PTRMS) while organic acids and SO2 concentrations were measured using a wet effluent diffusion denuder/ aerosol collector (WEDD/AC) connected to IC-MS. The particle chemical composition was measured using an Aerosol Time Of Flight Mass Spectrometer (ATOFMS, TSI, USA). The empirical particle nucleation and growth rates were determined using only the aerosol size distribution as input, using the recently developed inverse modelling procedure PARGAN (Particle Growth and Nucleation) (Verheggen and Mozurkewich 2006). Growth rates were determined by regression analysis of the General Dynamic Equation. The empirical growth rates were then used to estimate the time of nucleation for particles in each size bin, defined as the time when their diameter surpassed 1 nm. Their number density at the time and size of nucleation were determined by integrating the particle losses that occurred in the time interval between nucleation and measurement. The nucleation rate was then given by the rate at which particles grow past the critical cluster size, assumed to be 1 nm.
Charting the Landscape in Our Neighborhood from the PBHs Mass Distribution and GWs

We explicitly construct a double field inflationary model, which satisfies the latest PLANCK constraints at the CMB scales and produces the whole dark matter energy density as primordial black holes (PBHs), in the mass range $10^{-17}~M_{\odot}\lesssim M_{{}_{\rm PBH}}\lesssim 10^{-13}~M_{\odot}$. The PBHs are produced after the end of slow-roll inflation from the bubbles of true vacuum that nucleate during the course of inflation. Obtaining PBHs in this mass range enforces the scale of inflation to be extremely low, $10^{-7}~{\rm GeV}\lesssim H \lesssim 10^{-3} ~{\rm GeV}$, which makes the efforts to observe gravitational waves at the CMB scales futile. However, it is high enough to allow for a successful Big Bang Nucleosynthesis (BBN). Instead, exit from the rolling metastable direction to the true vacuum of the potential {\it may} happen with a first-order phase transition (PT) that leaves behind a stochastic gravitational wave background (SGWB), which is potentially observable by LISA. We show that PBHs produced during such a first-order PT from the collision of bubble walls contribute negligibly to the PBH mass spectrum. Examining the mass distribution of PBHs and possible SGWB from the end of inflation, we may be able to gain invaluable information about the topography of the landscape in our neighborhood.
Recent Results in the Field of Liquid Crystals

Thermotropic mesomorphous phases such as occur in the melts of many organic substances are considered. Though mesomorphous melts were first observed by Reinitzer in 1888, fundamental structural problems regarding such melts have not, as yet, been completely solved. Part I of this article deals mainly with such structural problems and with the theories of crystalline organic liquids. Part II describes the use of nematic solvents for magnetic resonance studies on oriented molecules. Examples are given to illustrate the possibilities offered by this procedure, and some of the results obtained so far are reviewed.
Procedures for Determining Influent COD Fractions and the Maximum Specific Growth Rate of Heterotrophs in Activated Sludge Systems

The influent COD of municipal wastewaters has been categorised into fractions: readily (soluble) and slowly (particulate) biodegradable, and soluble and particulate unbiodegradable. Procedures are presented for determining the division into these four categories, as are experimental methods for determining the maximum specific growth rate of the heterotrophs within the IAWPRC Task Group model structure. Some of the procedures are dependant on knowledge of the heterotroph yield and endogenous mass loss rate constants; comment is made on suggested values.

Hot carrier relaxation process in InGaN epilayers

InGaN epilayers with gallium fractions ranging between 0 and 0.48 have been studied by time‐resolved photoluminescence. Layers containing low gallium fractions are associated with low PL emission intensity. For In0.83Ga0. 17N layer, the luminescence decay is 100 times faster in the high energy part of the photoluminescence spectrum than on the low energy part, reflecting the hot carrier recombination process. This is confirmed by the significant blue shift of the photoluminescence spectra for short decay times compared to the time integrated spectrum. It takes about 10 ps for the carriers to reach an equilibrium temperature of 100 K.
An In-Depth Investigation of Performance Characteristics of Hyperledger Fabric

Private permissioned blockchains, such as Hyperledger Fabric, are widely deployed across the industry to facilitate cross-organizational processes and promise improved performance compared to their public counterparts. However, the lack of empirical and theoretical results prevent precise prediction of the real-world performance. We address this gap by conducting an in-depth performance analysis of Hyperledger Fabric. The paper presents a detailed compilation of various performance characteristics using an enhanced version of the Distributed Ledger Performance Scan. Researchers and practitioners alike can use the results as guidelines to better configure and implement their blockchains and utilize the DLPS framework to conduct their measurements.

Real-Time Observation on Water-Soluble Ions of PM2.5 in Beijing under the Influences of Different Air Masses in Summer

Abstract To further understand the variations of water-soluble ions in PM2.5 in Beijing, the authors observed their concentrations continuously and in high temporal resolution by the system for rapid collection of fine particles and ion chromatography (RCFP-IC) during 12–18 July 2010. These results combined with those of earlier backward trajectory research are used analyzed to determine the causes of concentration changes in water-soluble ions under the influences of two kinds of air masses in summer. The results indicate that concentrations of NO3−, SO42−, and NH4+ were influenced strongly by the continental air mass than by the marine air mass. Cl− and Na+ were not changed significantly. Because the sources of K+, Mg2+, and Ca2+ are mainly concentrated on land, their concentration levels were slightly higher under the control of continental air mass than that of the marine air mass. Variations of NO2− during the observation differed from those of other ions; its concentration was significantly higher under the influence of marine air mass. Moreover, the authors obtain the diurnal variations of eight water-soluble inorganic ions including NH4+, K+, Mg2+, Ca2+, Cl−, NO2−, NO3−, and SO42−. Diurnal variations of NH4+, NO3−, and Cl− showed single peak, which appeared before noon, while SO42− showed two peaks that appeared during rush hours. Those of Mg2+, Ca2+, and K+ showed single peak that appeared in the afternoon. That of NO2− showed with a peak appearing at sunrise and a valley appearing at sunset.
Reactivity of Oxide Surfaces and Metal-Oxide Interfaces: Effects of Water Vapor Pressure on Ultrathin Aluminum Oxide Films, and Studies of Platinum Growth Modes on Ultrathin Oxide Films and Their Effects on Adhesion

The reactivity of oxide surfaces and metal-oxide interfaces play an important role in many technological applications such as corrosion, heterogeneous catalysis, and microelectronics. The focus of this research was (1) understanding the effects of water vapor exposure of ultrathin aluminum oxide films under non-ultrahigh vacuum conditions (>10-9 Torr) and (2) characterization of Pt growth modes on ultrathin Ta silicate and silicon dioxide films and the effects of growth modes on adhesion of a Cu overlayer. These studies were conducted with X-ray photoelectron spectroscopy (XPS). Ni3Al(110) was oxidized (10-6 Torr O2, 800K) followed by annealing (1100K). The data indicate that the annealed oxide film is composed of NiO, Al2O3 and an intermediate phase denoted here as "AlOx". Upon exposure of the oxide film at ambient temperature to increasing water vapor pressure (10-6 - 5 Torr), a shift in both the O(1s) and Al(2p)oxide peak maxima to lower binding energies is observed. In contrast, exposure of Al2O3/Al(polycrystalline) to water vapor under the same conditions results in a high binding energy shoulder in the O(1s) spectra which indicates hydroxylation. Spectral decomposition provides further insight into the difference in reactivity between the two oxide films. The corresponding trends of the O(1s)/Ni0(2p3/2) and Al(2p)/Ni0(2p3/2) spectral intensity ratios suggest conformal changes of the oxide film on Ni3Al(110). The growth behavior of sputter deposited Pt at ~300K on Ta silicate and SiO2 ultrathin films formed on Si(100) was investigated. The XPS data show that Pt deposition results in uniform growth or "wetting" on Ta silicate and 2-D cluster growth on SiO2. Electroless Cu deposition on ~11 monolayers (ML) Pt/Ta silicate film results in an adherent Cu film which passed the Scotch tape test. In contrast, electroless Cu deposition on ~11ML Pt/SiO2 results in a non-adherent Cu film due to weak Pt/SiO2 interaction.

Chemical solution deposition of LaMnO3-based films for coated conductors

LaMnO3-based films were prepared using the chemical solution deposition method. It was found that the films on perovskite oxide single crystal substrates are highly (h00)-oriented when the annealing atmosphere is oxygen or air; however, when the substrate is yttrium-stabilized ZrO2, only the La1-xNaxMnO3 films are highly (h00)-oriented, and other LaMnO3-based films are (110)-oriented. Under a reducing annealing atmosphere, the atmosphere must be wet in order to create a suitable oxygen partial pressure to crystallize the LaMnO3-based films. After annealing under a wet reducing atmosphere the LaMnO3-based films are (110)-oriented when the films are directly deposited on Ni tapes; however, when SrTiO3-buffered Ni tapes are used, the LaMnO3 films are (h00)-oriented, which is suitable for subsequent growth of YBCO. The results suggest that it is possible to tune the orientation of buffer layers using suitable templates, which can widen the selection of buffer layers for coated conductors in the all metallorganic deposition approach.
Theoretical Study On The Reaction Mechanism Of Gecl3ch2ch2cooh+h2o→gecl2ohch2ch2cooh+hcl

The mechanism and dynamical properties for the title reaction have been investigated theoretically. Three reaction pathways have been found. Geometries, vibrational frequencies, infra-red (IR) intensities and relative energies for various stationary points in the three reaction channels have been determined respectively. The corresponding rate constants at the B3LYP/6-31++G(2d,2p) level have been deduced over a wide temperature range of 200–2000 K by using canonical variational transition state theory with small curvature tunnelling effect. Solvent effects are taken into account via the Onsager model of self-constant reaction field at the same level of theory. This preliminary study shows that the complex formation is favoured by the use of water solvent.
Length-weight relationship and relative condition factor of Schizothorax eurystomus Kessler, 1872 from Fergana valley

The focus was on the length-weight relationship and relative condition factor of Schizothorax eurystomus from Fergana Valley, which was studied for eight months (August-December, 2016, January 2017 and July-August, 2019). During the study, 125 fish samples were studied, including 16 females, 48 males and 61 immature, with a total body length from 6.16 to 29.2 cm and weight from 2.12 to 216.23 grams. The parameters “a” and “b” of the length-weight relationship were estimated using the equation W=aLb while the relative condition factor was also calculated from the equation, Wr = 100w/am Lbm. The regression coefficient “b” values were 2.7486; 3.0724; 3.1179 and 3.0874 for males, females, immature and combined sexes, respectively. The general results showed positive allometric growth (b>3) exhibited by the species. The mean “Wr” value for the females was 100.22±6.83, males 100.37±8.57, immature 100.27±7.45 while the combined sex was 100.37±8.53 and there was a significant difference among the sexes.
Measurement of Oxygen Transfer in Clean Water

\IMeasurement of Oxygen Transfer in Clean Water\N was developed to calculate the rate of oxygen transfer from diffused gas and mechanical oxygenation devices to water. The Standard is applicable to laboratory-scale oxygenation devices with small volumes of water as well as to full-scale systems with water volumes typical of those found in the activated sludge wastewater treatment process. It is intended that this standard be used by engineers in the preparation of specifications for compliance testing. This test method is based upon removal of dissolved oxygen (DO) from the water volume by sodium sulfite followed by reoxygenation to near the saturation level. The DO inventory of the water volume is monitored during the rearation period by measuring DO concentrations at several points, selected so that each point senses an equal tank volume. The method specifies a minimum number, distribution, and range of DO measurements at each point. This procedure is valid for a wide variety of mixing conditions. The primary result of this testing is expressed as the standard oxygen transfer rate. The Standard also describes how clean water tests can be applied to estimate oxygen transfer rate in process water. In addition, various components of power consumption are defined; methods for measurement of gas rate and power consumption by oxygenation devices are given; and the preparation of data analysis is discussed.
Primary thromboprophylaxis for inpatients with advanced cancer

Introduction: Thromboprophylaxis (TP) is recommended for acutely hospitalised cancer patients; little is known about its use on palliative care units (PCUs). Methods: First, we conducted a systematic review to explore the landscape of TP use, venous thromboembolism (VTE) and bleeding rates on PCUs. We then administered a fractional factorial survey to Canadian medical oncologists and palliative care physicians exploring their attitudes towards TP using a series of vignettes. Results: The systematic review revealed heterogeneity in TP use, VTE and bleeding rates. The survey revealed heterogeneity in decision-making around TP between the two physician groups. We identified a number of patient factors that contributed to TP use; oncologists were at higher odds of prescribing TP compared with palliative care physicians(OR 2.09[95%CI 1.562.8]). Conclusions: True rates of TP use, VTE and bleeding on PCUs remain unclear. Greater exploration of the drivers and barriers to TP use, and physician group differences, are warranted. iii Acknowledgements I am grateful for the mentorship of my Master’s supervisor, Dr. Monika Krzyzanowska.
