Convolutional Neural Network for Chinese Sentiment Analysis Considering Chinese Slang Lexicon and Emoticons

Nowadays, social media have become the essential part of our lives. Internet slang is an informal language used in everyday online communication which quickly becomes adopted or discarded by new generations. Similarly, pictograms (emoticons/emojis) have been widely used in social media as a mean for graphical expression of emotions. People can convey delicate nuances through textual information when supported with emoticons, and the eﬀectiveness of computer-mediated communication is also improved. Therefore, it is important to fully understand the inﬂuence of Internet slang and emoticons on social media. In this paper, we propose a convolutional neural network model considering Internet slang and emoticons for sentiment analysis of Weibo which is the most popular Chinese social media platform. Our experimental results show that the proposed method can signiﬁcantly improve the performance for predicting sentiment polarity.
A rapid review and meta-analysis of the asymptomatic proportion of PCR-confirmed SARS-CoV-2 infections in community settings

Background:Cross-sectional studies indicate thatup to 80% of active SARS-CoV-2 infections may be asymptomatic. However, accurate estimates of the asymptomatic proportion require systematic detection and follow-up to differentiate between truly asymptomatic and pre-symptomatic cases. We conducted a rapid review and meta-analysis of the asymptomatic proportion of PCR-confirmed SARS-CoV-2 infections based on methodologically appropriate studies in community settings.Methods:We searched Medline and EMBASE for peer-reviewed articles, and BioRxiv and MedRxiv for pre-prints published before 25/08/2020. We included studies based in community settings that involved systematic PCR testing on participants and follow-up symptom monitoring regardless of symptom status. We extracted data on study characteristics, frequencies of PCR-confirmed infections by symptom status, and (if available) cycle threshold/genome copy number values and/or duration of viral shedding by symptom status, and age of asymptomatic versus (pre)symptomatic cases. We computed estimates of the asymptomatic proportion and 95% confidence intervals for each study and overall using random effect meta-analysis. Results:We screened 1138 studies and included 21. The pooled asymptomatic proportion of SARS-CoV-2 infections was 23% (95% CI 16%-30%). When stratified by testing context, the asymptomatic proportion ranged from 6% (95% CI 0-17%) for household contacts to 47% (95% CI 21-75%) for non-outbreak point prevalence surveys with follow-up symptom monitoring. Estimates of viral load and duration of viral shedding appeared to be similar for asymptomatic and symptomatic cases based on available data, though detailed reporting of viral load and natural history of viral shedding by symptom status were limited. Evidence into the relationship between age and symptom status was inconclusive.Conclusion:Asymptomatic viral shedding comprises a substantial minority of SARS-CoV-2 infections when estimated using methodologically appropriate studies. Further investigation into variation in the asymptomatic proportion by testing context, the degree and duration of infectiousness for asymptomatic infections, and demographic predictors of symptom status are warranted.
The Critical Micelle Concentration of Asphaltenes As Measured by Calorimetry

Micellization of asphaltenes in solution has been investigated using a micro calorimetric titration procedure (Andersen, S. I.; Birdi, K. S. J. Colloid Interface Sci. 1991, 142, 497). The method uses the analysis of heat of dissociation and dilution of asphaltene micelles when a pure solvent (or solvent mixture) is titrated with a solution of asphaltene in the same solvent. The asphaltene concentration of the injected solution is at a level above the critical micelle concentration (CMC). In the present paper the procedure is applied in investigation of asphaltenes as well as subfractions of asphaltenes obtained by solvent extraction with toluene/heptane mixtures. These subfractions get more complex in structure as the toluene content of the extraction solvent increases and at the same time the CMC of the asphaltenes in pure toluene decreases. There is an indication that the presence of “lower” asphaltene species leads to less association in solution due to the interaction between these and the heavier asp.
EdgeDIPN: a Unified Deep Intent Prediction Network Deployed at the Edge

With the rapid growth of e-commerce in recent years, e-commerce platforms are becoming a primary place for people to find, compare and ultimately purchase products. To improve online shopping experience for consumers and increase sales for sellers, it is important to understand user intent accurately and be notified of its change timely. In this way, the right information could be offered to the right person at the right time. To achieve this goal, we propose a unified deep intent prediction network, named EdgeDIPN, which is deployed at the edge, i.e., mobile device, and able to monitor multiple user intent with different granularity simultaneously in real-time. We propose to train EdgeDIPN with multi-task learning, by which EdgeDIPN can share representations between different tasks for better performance and saving edge resources in the meantime. In particular, we propose a novel task-specific attention mechanism which enables different tasks to pick out the most relevant features from different data sources. To extract the shared representations more effectively, we utilize two kinds of attention mechanisms, where the multi-level attention mechanism tries to identify the important actions within each data source and the inter-view attention mechanism learns the interactions between different data sources. In the experiments conducted on a large-scale industrial dataset, EdgeDIPN significantly outperforms the baseline solutions. Moreover, EdgeDIPN has been deployed in the operational system of Alibaba. Online A/B testing results in several business scenarios reveal the potential of monitoring user intent in real-time. To the best of our knowledge, EdgeDIPN is the first full-fledged real-time user intent understanding center deployed at the edge and serving hundreds of millions of users in a large-scale e-commerce platform.

The bond-forming reaction between CF22+ and H2O/D2O: A computational and experimental study

Ground-state stationary points on the potential energy surface of the reaction CF22++H2O→OCF++HF+H+ were calculated using the density-functional theory hybrid method B3LYP and the ab initio coupled cluster singles and doubles with perturbative triples [CCSD(T)] algorithm. The calculations reveal a reaction mechanism involving two transition states. The first transition state involves the migration of one hydrogen within the primary collision complex and the second corresponds to the loss of a proton. The neutral HF molecular product is formed in its stable ground 1Σ state. Comparison of activation energies for the reactions of CF22+ with H2O and with D2O, calculated from Becke three parameter Lee–Yang–Parr (B3LYP) zero-point energies, slightly favor the H2O pathway by 0.04 and 0.07 eV for the first and second activations, respectively. Rate constant calculations using Rice–Ramsperger–Kassel–Marcus/quasiequilibrium theory also kinetically favor the H2O pathway in comparison with the D2O pathway. However, t.

Findings have crucial implications for policymakers who provide regulations for the above derivative markets and for investors, who invest long-term into FIRST BITCOIN CAP.
The Commodification of Religion: A Rhetorical Analysis of Charismatic Programmes in Kenya

This paper discusses dominant human afflictions that variously become exigencies for a rhetorical situation in commodifying the spiritual experience by televangelists in Kenya. The commodification of religion is a rarity in contemporary media and communication research in Africa. It can, however, be explored in the context of „mediated spirituality‟, by acknowledging the place of communication technologies such as Television, in the mediation of religious content. This interplay between media and religion has arguably availed opportunities through which religion is commodified by converting some aspects of religion into spiritual commodities through a near capitalistic exchange. The study utilized Kenneth Burke‟s rhetorical theory, which is a plausible instrument for examining a communicator‟s motive in structuring audience perception to influence behaviour aimed at eliciting certain desired responses. The paper argues that charismatic Televangelists use common spiritual, physical and economic afflictive conditions notably; disease, poverty and demonic oppression, to commodify religion through creative message construction to trigger a reciprocate process of material exchange for the spiritual benefit obtained. The paper submits that these charismatic programme creators are not only concerned with edification and spiritual nourishment of their audiences but are substantially motivated by the inherent exchange value of religion through which human afflictions are rhetorically appropriated to provoke reciprocity for the spiritual benefit obtained.

Globalization and Real Estate Development in Nigeria- An Empirical Perspective

The aim of this study is to examine the impact of globalization on real estate development in Nigeria. The motivation for this study lies in the compelling need to empirically investigate the spillovers of globalization on the development of real estate in Nigeria in which past studies have not sufficiently explored. Data were collected from the UNCTAD, WDI and Central Bank of Nigeria Statistical Bulletin from 1990 to 2016. Consequently, the long-run effect indicates that FDI and real estate development have a significant positive relationship in Nigeria. In addition, there is one way feedback relationship which runs from FDI to real estate development in the country. This implies that globalization has been beneficial to the development of real estate sub sector in Nigeria. Moreover, this paper makes the following recommendations for the policy makers, investors and future researchers in the country. The spillovers of globalization on real estate sectors development in Nigeria should not be undermined. Therefore, the policy makers in the country should embark on policy measures that will ensure a conducive climate for foreign investors to thrive in this sector of the economy. Also, the federal government of Nigeria should not hesitate to address all the institutional hurdles that could frustrate the maximum spillover benefits of globalization in real estate development in the nearest future in this country.
Potential energy surfaces in algebraic molecular models using coherent states

The potential energy surfaces provided by the coherent states formalism for the case of interacting one-dimensional oscillators is investigated. The case of two interacting oscillators modelled with Morse potentials are considered in detail. First the traditional treatment is presented in order to identify the need to establish a new transformation between the parameters and the classical variables that allow the full Hamiltonian to be recovered. To this end the connection between the su(2) algebraic model and the usual treatment in configuration space was taken into account. It is shown that the coherent state approach when applied to recover the potential energy surface (PES) from a polyad preserving Hamiltonian is viable only in systems with a local mode behaviour. For molecules with a normal mode behaviour the approach is still valid, but the polyad must be broken in order to recover the PES. Our approach is evaluated through the calculation of the force constants for H2O and CO2, representative examples of local and normal behaviours.
Optimal sensor placement for event detection and source identification in water distribution networks

This study focuses on the optimization of sensor placement with respect to the source identification and event detection. A multi-objective algorithm is used to solve the optimization problem. The numbers of possible source nodes for contamination events associated with the solutions on the Pareto fronts from the proposed method and benchmark method are calculated under the same configuration and compared. The comparison showed that the proposed method performs better than the benchmark method in detecting a contamination event and identifying its possible source.
Advances in Computational Solvation Thermodynamics

OF THE DISSERTATION Advances in Computational Solvation Thermodynamics by Matthew A. Wyczalkowski Doctor of Philosophy in Biomedical Engineering Washington University in St. Louis, 2009 Research Advisor: Professor Rohit V. Pappu The aim of this thesis is to develop improved methods for calculating the free energy, entropy and enthalpy of solvation from molecular simulations. Solvation thermodynamics of model compounds provides quantitative measurements used to analyze the stability of protein conformations in aqueous milieus. Solvation free energies govern the favorability of the solvation process, while entropy and enthalpy decompositions give insight into the molecular mechanisms by which the process occurs. Computationally, a coupling parameter λ modulates solute-solvent interactions to simulate an insertion process, and multiple lengthy simulations at a fixed λ value are typically required for free energy calculations to converge; entropy and enthalpy decompositions generally take 10-100 times longer. This thesis presents three advances which accelerate the convergence of such calculations:
Investigation of the reaction of cisplatin with methionine in aqueous media using HPLC-ICP-DRCMS

The reaction of cisplatin with methionine was studied by high performance ion chromatography coupled to inductively coupled plasma mass spectrometry equipped with dynamic reaction cell technique (HPLC-ICP-DRCMS) at two different cisplatin concentrations simulating chemotherapy conditions and waste water levels. The reaction of cisplatin with methionine was monitored over a period of 16 h. Accurate quantification of all platinum containing compounds was achieved via species unspecific on-line isotope dilution mass spectrometry. A limit of detection (LOD) of 0.31, 0.25, 3.83, 1.07, 0.56, 0.82 and 2.38 µg L−1 was calculated at m/z 194 for cisplatin, monoaquacisplatin, diaquacisplatin and the four platinum containing adducts, respectively. Stoichiometric platinum/sulfur ratios were assessed for characterization of the four adducts using ICP-DRCMS detection employing oxygen as reaction gas. An excellent sulfur detection limit of 1.30 µg L−1 could be achieved by HPLC-ICP-DRCMS (20 µL injection volume). At high cisplatin levels (0.6 mmol L−1) typical in chemotherapy, it was found that adducts show different kinetic behavior depending on the two investigated chloride levels (1.5 and 150 mmol L−1). Moreover, the reaction course depended on the concentration of the reactants, i.e. cisplatin and methionine. Experiments simulating possible reactions of the compounds in the aquatic environment revealed that at low µmol L−1 levels no adduct formation occurred. Finally, the stability of the four adducts potentially formed during chemotherapy was investigated representing the dilution of patient urine via hospital waste water. A considerable amount of highly active monoaquacisplatin was formed, indicating a reversal of detoxification reaction pathways of the human body.
High-Yield Lithium-Injection Fusion-Energy (HYLIFE) reactor

The High-Yield Lithium-Injection Fusion Energy (HYLIFE) concept to convent inertial confinement fusion energy into electric power has undergone intensive research and refinement at LLNL since 1978. This paper reports on the final HYLIFE design, focusing on five major areas: the HYLIFE reaction chamber (which includes neutronics, liquid-metal jet-array hydrocynamics, and structural design), supporting systems, primary steam system and balance of plant, safety and environmental protection, and costs. An annotated bibliography of reports applicable to HYLIFE is also provided. We conclude that HYLIFE is a particularly viable concept for the safe, clean production of electrical energy. The liquid-metal jet array, HYLIFE's key design feature, protects the surrounding structural components from x-rays, fusion fuel-pellet debris, neutron damage and activation, and high temperatures and stresses, allowing the structure to last for the plant's entire 30-year lifetime without being replaced. 127 refs., 18 figs.
Consumo, digestibilidade de nutrientes e parâmetros sanguíneos de cabras mestiças moxotó suplementadas com óleos de licuri ou mamona

The objective of this research was to evaluate the possibility of including Castor or Licuri oil at two levels in the diets of crossbred Moxoto goat's through dry matter intake, digestibility and levels of urea, glucose and nonesterified fatty acids (NEFA) in the blood. The treatments consisted of control groups without oil, 3% or 5% of Licuri (LO-3 or LO-5) or Castor (CO-3 or CO-5) oil, based on dry matter supplementation. Ten Moxoto lactating goats were used according to a double Latin Square (5 x 5) experiment design. The addition of oil to the diet reduced the dry matter intake, except for animals that were supplemented with CO-3. However, the addition of 3% of oil didn´t alter the intake of metabolizable energy and crude protein. The animals supplemented with LO-5 oil showed smaller nutrients intake, except for ether extract intake. The lipid supplement didn´t alter the dry matter digestibility, however increased the NDF digestibility the CP and EE apparent digestibility. There was no difference among the glucose levels, urea and NEFA in the blood. It is possible to use 3 %Castor oil in the diet of lactating goats.
A novel method for the solution of the Schrödinger equation in the presence of exchange terms

In the Hartree–Fock approximation the Pauli exclusion principle leads to a Schrodinger equation of an integro-differential form. We describe the extension of a new spectral noniterative method (S-IEM), previously developed for solving the Lippmann–Schwinger integral equation with local potentials, so as to include the exchange nonlocality. We apply it to the restricted case of electron-hydrogen scattering in which the bound electron remains in the ground state and the incident electron has zero angular momentum, and we compare the acuracy and economy of the new method to two other methods. One is a noniterative solution of the integral equation as described by Sams and Kouri in 1969. Another is an iterative method introduced by Kim and Udagawa in 1990 for nuclear physics applications, which makes an expansion of the solution into an especially favorable basis obtained by a method of moments. The S-IEM method turns out to be more accurate than the two comparison methods by many orders of magnitude for the .
Synthesis and acetylcholinesterase inhibitory activity of several pyrimidone analogues of huperzine A

Syntheses of four new pyrimidone analogues of the acetylcholinesterase (AChE) inhibitor huperzine A are reported together with the inhibitory potencies of these compounds for foetal bovine calf serum AChE; β-lactone formation followed by a thermal cycloreversion reaction serves as the key step for introduction of the ethylidene appendage of 12 in the stereochemically correct form.
Ferroic phase transition sequence in epitaxial BiFeO3 thin films

We report a temperature-dependent high-resolution X-ray diffraction investigation of 200 nm epitaxial BiFeO3 thin films grown on (001) SrTiO3. We were successful in making epitaxial thin films thermally stable, a key requirement for this study. Our results provide evidence that BiFeO3 undergoes three high-temperature transitions: an antiferromagnetic transition at 425°C, a first-order α–β phase transition between 745°C and 780°C and a smoother transition toward the γ-phase at 860°C. Both the α–β and β–γ transitions take place 60°C lower than the bulk values whereas the antiferromagnetic transition occurs 55°C higher. This underscores the part played by strain and also emphasizes that BiFeO3 is not a conventional ferroelectric perovskite. Reciprocal space maps reveal the unusual result that the thin films remain monoclinic on crossing the α–β phase transition. Linear extrapolation of the in-plane lattice parameters to higher temperatures rules out cubic symmetry for the γ-phase.
Influence of metal organic chemical vapor deposition growth parameters on the luminescent properties of ZnO thin films deposited on glass substrates

Highly c-axis oriented zinc oxide (ZnO) thin films with a wurtzite structure have been grown on glass substrates by metal organic chemical vapor deposition. The influence of growth parameters on the luminescent properties of the ZnO layers is investigated. It is shown that the growth temperature and VI/II ratio strongly influence the luminescent properties of ZnO thin films. For the films grown at low temperatures (250–325°C) a broad violet emission band at about 3.1eV has been observed. As the growth temperature increases, ultraviolet emission dominates the spectra and deep level emission is suppressed. It is suggested that the violet emission depends on grain size and hence the width of the free-carrier depletion region at the particle surface; the narrower the depletion width compared to the grain size, the higher the intensity. The result suggests that the mechanism responsible for the violet emission is recombination of delocalized electrons close to the conduction band with holes trapped in neutral .
