Lexicon‐pointed hybrid N‐gram Features Extraction Model (LeNFEM) for sentence level sentiment analysis

Sentiment analysis of social media textual posts can provide information and knowledge that is applicable in social settings, business intelligence, evaluation of citizens' opinions in governance, and in mood triggered devices in the Internet of Things. Feature extraction and selection is a key determinant of accuracy and computational cost of machine learning models for such analysis. Most feature extraction and selection techniques utilize bag of words, N‐grams, and frequency‐based algorithms especially Term Frequency‐Inverse Document Frequency. However, these approaches do not consider relationships between words, they ignore words' characteristics and they suffer high feature dimensionality. In this paper we propose and evaluate a feature extraction and selection approach that utilizes a fixed hybrid N‐gram window for feature extraction and minimum redundancy maximum relevance feature selection algorithm for sentence level sentiment analysis. The approach improves the existing features extraction techniques, specifically the N‐gram by generating a hybrid vector from words, Part of Speech (POS) tags, and word semantic orientation. The vector is extracted by using a static trigram window identified by a lexicon where a sentiment word appears in a sentence. A blend of the words, POS tags, and the sentiment orientations of the static trigram are used to build the feature vector. The optimal features from the vector are then selected using minimum redundancy maximum relevance (MRMR) algorithm. Experiments were carried out using the public Yelp dataset to compare the performance of the proposed model and existing feature extraction models (BOW, normal N‐grams and lexicon‐based bag of words semantic orientations). Using supervised machine learning classifiers the experimental results showed that the proposed model had the highest F‐measure (88.64%) compared to the highest (83.55%) from baseline approaches. Wilcoxon test carried out ascertained that the proposed approach performed significantly better than the baseline approaches. Comparative performance analysis with other datasets further affirmed that the proposed approach is generalizable.
A Study on Visual Saliency Detection in Infrared Images Using Boolean Map Approach

Visual saliency detection is an essential task because it is an important part of various vision-based applications. There are many techniques for saliency detection in color images. However, the number of methods for saliency detection in infrared images is limited. In this paper, we introduce a simple approach for saliency detection in infrared images based on the thresholding technique. The input image is thresholded into several Boolean maps, and an initial saliency map is calculated as a weighted sum of the created Boolean maps. The initial map is further refined by using thresholding, morphology operation, and a Gaussian filter to produce the final, high-quality saliency map. The experiment showed that the proposed method has high performance when applied to real-life data.
Distributed optimal congestion control and channel assignment in wireless mesh networks

Wireless mesh networks have numerous advantages in terms of connectivity as well as reliability. Traditionally the nodes in wireless mesh networks are equipped with single radio, but the limitations are lower throughput and limited use of the available wireless channel. In order to overcome this, the recent advances in wireless mesh networks are based on multi-channel multiradio approach. Channel assignment is a technique that selects the best channel for a node or to the entire network just to increase the network capacity. To maximize the throughput and the capacity of the network, multiple channels with multiple radios were introduced in these networks. In the proposed system, algorithms are developed to improve throughput, minimise delay, reduce average energy consumption and increase the residual energy for multi radio multi-channel wireless mesh networks. In literature, the existing channel assignment algorithms fail to consider both interflow and intra flow interferences. The limitations are inaccurate bandwidth estimation, throughput degradation under heavy traffic and unwanted energy consumption during low traffic and increase in delay. In order to improve the performance of the network distributed optimal congestion control and channel assignment algorithm (DOCCA) is proposed. In this algorithm, if congestion is identified, the information is given to previous node. According to the congestion level, the node adjusts itself to minimise congestion.
Population Discrimination by Strontium-calcium Concentration Ratios of Sagittal Otoliths Taken from the Japanese Flounder, Paralichthys olivaceus

For the purpose of obtaining basic data to understand the population dynamics of the Japanese flounder, Paralichthys olivaceus, inhabiting the Sanriku coastal waters, the concentration ratios of Ca and Sr in otoliths of juvenile fishes being cultivated for releasing to the regions, and those of adult fishes captured in both the Sanriku area (Aomori, Iwate and Miyagi) and Shizuoka prefecture coastal regions (as a comparison) were analysed using a particle induced X-ray emission (PIXE) technique. The Sr/Ca ratios of otoliths taken from juvenile Japanese flounders had significant differences between Sanriku and Shizuoka sea-farming groups. The differences in otolith Sr/Ca ratios between Sanriku and Shizuoka sea-farming stations would thus differentiate flounder populations. No significant difference in otolith Sr/Ca ratios was observed among the Sanriku group. However, the values for Aomori group formed by small fishes in the Sanriku group seemed to be lower in proportion to their body size. Therefore, genetic characteristics of the juvenile Japanese flounder being reared at the sea-farming stations in Iwate and Miyagi prefectures are possibly different from those at an Aomori station. On the other hand, statistically significant differences in the otolith Sr/Ca ratios among Aomori, Iwate, Miyagi and Shizuoka groups were found in the adult Japanese flounder. That is, higher values for the otolith Sr/Ca ratios were found in the groups inhabiting in the northern regions. The differences in otolith Sr/Ca ratios among these groups probably indicate that there are differences in the fish populations among these sample sites.
Decomposition Behavior of PCDD/F Isomers in Incinerator Gases under Electron-Beam Irradiation

The decomposition behavior under electron-beam irradiation was examined for polychlorinated dibenzo-p-dioxin (PCDD, polychlorinated dibenzo[b,e][1,4]dioxin) and polychlorinated dibenzofuran (PCDF) isomers in incinerator gases at a temperature of 473 K. Significant decomposition was obtained for all PCDD isomers over the investigated absorbed doses, which resulted from oxidation reactions with OH radicals yielded by electron-beam irradiation. In the case of PCDFs, specific isomers having symmetrical structures, such as 1,2,8,9-, 2,3,7,8-, and 3,4,6,7-TeCDFs, were yielded through the dechlorination of PeCDF isomers. Thermal electrons probably played a role in the dechlorination of PeCDF isomers. Simultaneous formation and subsequent destruction were observed in the electron-beam treatment of TeCDFs in incinerator gases.

An Intercomparison of Measurement Methods for Carbonaceous Aerosol in the Ambient Air in New York City

Measurement methods for fine carbonaceous aerosol were compared under field sampling conditions in Flushing, New York during the period of January and early February 2004. In-situ 5- to 60-minute average PM 2.5 organic carbon (OC), elemental carbon (EC), and black carbon (BC) concentrations were obtained by the following methods: Sunset Laboratory field OC/EC analyzer, Rupprecht and Patashnick (R&P) series 5400 ambient carbon particulate monitor, Aerodyne aerosol mass spectrometer (AMS) for total organic matter (OM), and a two-wavelength AE-20 Aethalometer. Twenty-four hour averaged PM 2.5 filter measurements for OC and EC were also made with a Speciation Trends Network (STN) sampler. The diurnal variations in OC/EC/BC concentrations peaked during the morning and afternoon rush hours indicating the dominant influence of vehicle emissions. BC/EC slopes are found to range between 0.86 and 1.23 with reasonably high correlations (r > 0.75). Low mixing heights and absence of significant transported carbonaceous aerosol are indicated by the measurements. Strong correlations are observed between BC and thermal EC as measured by the Sunset instrument and between Sunset BC and Aethalometer BC. Reasonable correlations are observed among collocated OC/EC measurements by the various instruments.

Optimization of the Process for Recovering Phenolic Antioxidant Compounds from Low-Quality Eggplant (Solanum melongena L.) Pulp by Modified Supercritical Carbon Dioxide Extraction

The extraction of biologically active compounds from eggplant pulp by modified supercritical CO2 extraction was investigated. Response surface methodology was used to optimize the extraction of phenolic compounds and antioxidant capacity by assessing the pressure, temperature, and cosolvent percentage. The results demonstrated that the maximum phenolic content (3,530.79 mg CAE/100 g extract) and antioxidant capacity (4,593.22 μmol TE/g extract) were observed at 56.8°C, 280 bar, and 1.22% of ethanol and were higher than those obtained by conventional solvent extraction. Four phenolic acids were identified in the supercritical extracts and not in the conventional extracts using HPLC-DAD analysis, suggesting that modified supercritical CO2 extraction is more efficient and selective.

Some developments in direct nuclear energy conversion: Neutron flux dependence of the fission electric cell output parameters

The output parameters of different types of vacuum (VAFEC) and gas filled (GAFEC) fission electric cells (FECs) have been measured during their irradiation in the nuclear reactor of the Central Institute of Physics in Bucharest, Romania, at different thermal neutron flux (ϕnth) values in the 108…1012 neutrons/cm2 s range. These measurements allowed us to estimate to what degree the FEC output parameters depend on the ϕnth variation and pointed out the differences in the operation of the VAFEC and GAFEC-type devices. The main results for some of the tested FECs are presented.
Nitrogen mineralization from paddy and upland soils under flooded and nonflooded incubation

An incubation study was carried out to compare the mineralization of soil organic N under flooded conditions with that under nonflooded conditions. Soils used in this incubation were air-dried paddy soils (37 samples), air-dried upland soils (22 samples), and fresh-moist paddy soils (7 samples). The amount of mineralization of soil organic N was larger under flooded incubation than under nonflooded incubation, in all the soil samples used. The differences in the amount of N mineralized between flooded and nonflooded incubation were generally larger for air-dried paddy soil samples than for air-dried upland soil samples.
Separation of Alcohols from Solution by Lignin Gels

Abstract Partition relationships of radioisotope labeled ethanol and 1-butanol between aqueous solutions and a hydrated commercial Kraft softwood lignin gel are presented. These initial evaluations indicate that lignin hydrogels preferentially concentrate 1-butanol and, to a lesser extent, ethanol. The process implications and potential use of lignin as an inexpensive extractant are discussed.
Measurement of Activity Coefficients at Infinite Dilution in Solvent Mixtures Using the Dilutor Technique

The knowledge of activity coefficients at infinite dilution (γ∞) are of particular importance for the synthesis, design, and optimization of separation processes because the largest separation effort is required to remove the last traces of impurities. Furthermore, reliable γ∞ values are required to select selective solvents (entrainers) for separation processes such as extractive distillation, extraction, and so forth or to check for separation problems (azeotropic points and miscibility gaps). Various experimental techniques for the determination of limiting activity coefficients in pure solvents have been developed. In this paper γ∞ values for different hydrocarbons (n-hexane, cyclohexane, 1-hexene, and benzene) for NMP/water mixtures measured with the help of the dilutor technique in the temperature range between 30 and 60 °C are reported, which can be used to select and to optimize the selectivity and capacity for the separation of aliphatics from aromatic or alkanes from alkenes using NMP/water mixt.
Primary Science Teachers’ Self-Efficacy and Outcome Expectancy: A Case Study

Self-efficacious teachers are critical in the development of students’ positive attitudes towards science and scientific literacy yet to date little attention has been given to studies of experienced teachers of primary science and development of their self-efficacy (SE) beliefs. The aim of this study was to explore how two experienced teachers of primary science built their SE beliefs and outcome expectancy. Bandura’s (1977) SE framework provided the conceptual lens to understand participants’ experiences and beliefs. Findings suggest that teachers’ SE beliefs had developed over time, creating a foundation for a strong expectancy outcome. Each of the sources of influence made a significant contribution to their beliefs about their science teaching capability and the value of science. Seemingly, their strong outcome expectancy enabled them to be persistent and resilient, overcoming challenges as they arose. We argue that a strong expectancy outcome is necessary to ensure SE does not weaken over time.
Investigations on First Confirmed Outbreak of Ovine Theileriosis (Theileria luwenshuni) from Maharashtra State, India

Background: Clinical theileriosis of small ruminants is tick-borne disease caused by Theileria lestoquardi, Theileria uilenbergi and Theileria luwenshuni. Theileria annulata, the causative agent of bovine tropical theileriosis in cattle, can also infect sheep but does not cause any significant illness. It is one of the economically important diseases. There are no reports of ovine clinical theileriosis from Maharashtra state and there is paucity of information on its epidemiology. This paper reports first confirmed outbreak of ovine theileriosis based on clinical signs, microscopic examination, PCR and sequencing in the Maharashtra State of India. Methods: Whole blood samples from 22 ailing sheep were collected and subjected to hematological examination. Blood smears stained with Leishman’s stain were examined under 100X objective of the microscope. The blood samples from sheep found positive by microscopic method were subjected to PCR detection of 18S rRNA gene of hemoprotozoa and then for nucleotide sequencing and sequence analysis.Conclusion: Samples from 14 out of 22 sheep were found positive for piroplasms of Theileria spp by light microscopy. All positive samples were further confirmed by PCR detection of 18S rRNA gene of hemoprotozoa. PCR amplification yielded expected product of 1750 bp for all samples. BLAST and phylogenetic analysis of one sample revealed high sequence homology with T. luwenshuni reported from India and other countries. Characteristic clinical signs like fever, progressive anaemia, laboured breathing, lymphadenopathy, debility and non-responsiveness to antibiotic therapy were recorded. The animals responded to specific treatment against theileriosis. It is the first ever confirmed report of ovine theileriosis in Maharashtra state of India and hence reported.
First-principles study of phase transition and elastic properties of ScSb and YSb compounds

The phase transition of ScSb and YSb from the NaCl-type (B1) structure to the CsCl-type (B2) structure is investigated by the ab initio plane-wave pseudopotential density functional theory method. It is found that the pressures for transition from the B1 structure to the B2 structure obtained from the equal enthalpies are 38.3 and 32.1 GPa for ScSb and YSb, respectively. From the variations of elastic constants with pressure, we find that the B1 phase of ScSb and YSb compounds are unstable when applied pressures are larger than 46.3 and 64.2 GPa, respectively. Moreover, the detailed volume changes during phase transition are analyzed.
Development of a Stochastic Individual Path (SIP) Model for Predicting the Deposition of Pharmaceutical Aerosols: Effects of Turbulence, Polydisperse Aerosol Size, and Evaluation of Multiple Lung Lobes

In this study, a new computational fluid dynamics (CFD) modeling approach for pharmaceutical aerosols is further developed by evaluating the effects of turbulence, polydisperse aerosol size distribution, and multiple lung lobes on deposition in the mouth–throat (MT) and entire tracheobronchial (TB) airways. To evaluate a range of respiratory drug delivery conditions, a model dry powder inhaler (DPI; NovolizerTM) and a model spray soft-mist inhaler (SMI; RespimatTM) were considered. The respiratory geometry consisted of a previously developed characteristic MT and complete upper TB geometry through the third bifurcation (B3). More distal TB airways were simulated using stochastic individual path (SIP) models extending into each of the five lung lobes through bifurcation B15. Based on comparisons with new in vitro deposition data, results indicated that the low Reynolds number (LRN) k–ω turbulence model with near-wall corrections for anisotropic turbulence and velocity conditions accurately predicted deposited drug mass from both inhalers. Simulating the polydisperse aerosol size distribution had a large impact on overall deposited drug mass compared with a monodisperse approximation. However, a new equivalent mass median diameter (MMD), calculated as MMDeq = 1.25 × MMD, was shown to provide a good monodisperse estimate of the aerosol deposition from both inhalers considered in this study used with different inhalation flow conditions in the SIP models. Large variations in deposition were observed among the five lung lobes. However, deposition in the left lower lobe (scaled by a factor of 5) was found to be characteristic of total lobar deposition in the range of B4–B15 and allowed for the simulation of only one lobe. Implementing the approximations of an equivalent MMD and simulating deposition in one characteristic lung lobe increased the efficiency of the airway CFD simulations by over 25 times at the expense of a maximum 12% relative error compared with the more exact simulations. As an example of model utility, results indicated that the state-of-the-art SMI improved delivery efficiency of drug by a factor of 1.5 in the upper TB region and by over an order of magnitude in the lower TB airways compared with a commonly used high quality DPI.
