Formation mechanisms of atmospheric nitrate and sulfate during the
winter haze pollution periods in Beijing: gas-phase, heterogeneous
and aqueous-phase chemistry

Abstract. A vast area in China is currently going through severe haze episodes with drastically elevated concentrations of PM2.5 in winter. Nitrate and sulfate are main constituents of PM2.5 but their formations via NO2 and SO2 oxidation are still not comprehensively understood, especially under different pollution or atmospheric relative humidity (RH) conditions. To elucidate formation pathways of nitrate and sulfate in different polluted cases, hourly samples of PM2.5 were collected continuously in Beijing during the wintertime of 2016. Three serious pollution cases were identified reasonably during the sampling period and the secondary formations of nitrate and sulfate were found to make a dominant contribution to atmospheric PM2.5 under the relatively high RH condition. The significant correlation between NOR and NO2 × O3 during the nighttime under the RH ≥ 60 % condition indicated that the heterogeneous hydrolysis of N2O5 involving aerosol liquid water was responsible for the nocturnal formation of nitrate at the extremely high RH levels. The more coincident trend of NOR and HONO × DR (direct radiation) × NO2 than Dust × NO2 during the daytime under the 30 % < RH < 60 % condition provided convincing evidence that the gas-phase reaction of NO2 with OH played a pivotal role in the diurnal formation of nitrate at moderate RH levels. The extremely high mean values of SOR during the whole day under the RH ≥ 60 % condition could be ascribed to the evident contribution of SO2 aqueous-phase oxidation to the formation of sulfate during the severe pollution episodes. Based on the parameters measured in this study and the known sulfate production rate calculation method, the oxidation pathway of H2O2 rather than NO2 was found to contribute greatly to the aqueous-phase formation of sulfate.
Practically Efficient Group Signature Scheme

Group signature schemes enable a set of members to anonymously sign data on behalf of the entire group. In order to prevent misuse, a designated group managerhas the ability to trace a given signature back to a member. Other extensions can also be realized in speci? ffically designed schemes, such as veri? fier local revocation (VLR) wherein only the verifi? er needs information about the validity status of signing key pairs. This paper contributes two results towards group signature schemes. First, we present a new design for a group signature scheme that is secure under the standardmodel, with common relaxations for anonymity. The scheme also enables VLR and allows for fully-dynamic groups; i.e. groups that allow members to both leave and join after creation. Secondly, we implement a preliminary version of the scheme to begin investigating the effi? ciencies gained through utilizing one-time signing keys, instead of the traditional non-interactive, zero-knowledge proof systems.
Assessment of thermodynamic data for CuCrO2 delafossite from calorimetric measurements

A detailed investigation of the thermodynamic properties of delafossite CuCrO2 was carried out by experimental methods on synthetic CuCrO2 delafossite samples (differential scanning calorimetry from ambient to 871 K and drop calorimetry from 823 to 1123 K) and theoretical methods (density functional theory). Based on these data and available literature (low temperature heat capacity measurements and calculations, high temperature emf data), we propose, for the first time, a full set of thermodynamic data for the phase CuCrO2. Our selection comes to: ° H CuCrO ( ) f 298 2 =−670.8 ± 1.3 kJ mol−1, ° S CuCrO ( ) 298 2 =88.9 J K−1, and ° cp = T T T ( ) 1.02564. 10 2.87159. 10 1.28542. 10 2 7 3 5 1.5 (298 < T < 1300 K).
Outcome of Prevention of Mother to Child Transmission (PMTCT) of HIV Services at the University of Port Harcourt Teaching Hospital (UPTH), Port Harcourt, Nigeria

Background: Mother to Child Transmission (MTCT) of HIV causes over 90% of Paediatric HIV and its prevention must be targeted to curb this scourge. Objective: To determine the associated risk factors and outcome (HIV status) of HIV-exposed babies at the University of Port Harcourt Teaching Hospital (UPTH). Methodology: This was a prospective study carried out at the Paediatric HIV clinic of UPTH. Information on sociodemographic data of the babies, age at referral, when the mother’s HIV status was diagnosed, HAART use status of the mother, place of ANC and delivery, method of delivery, feeding option, duration of breast feeding and HIV status of the babies were obtained. Obtained data was analysed and a pvalue of < 0.05 was considered significant at 95% confidence interval. Result: A total of two hundred and sixty HIV exposed children were seen over the study period, with a male: female ratio of 1.4:1. The overall MTCT rate was 6.2%. Among the mothers that had the complete PMTCT intervention, an MTCT rate of 1.1% was observed, while it was 28.6% among mothers who had no form of PMTCT. Identified statistically significant risk factors to MTCT include; lack of use of HAART (χ 2 =116.2, p=0.0001); No infant ARV prophylaxis (p=0.0001); Mixed feeding Original Research Article Paul and Ugwu; AJMAH, 17(2): 1-11, 2019; Article no.AJMAH. 53046 2 (p=0.0001); Prolonged breast feeding (χ 2 = 7.09, P= 0.0287); TBA supervised pregnancy (χ =31.9, P= 0.0001) and delivery (χ 2 =61.47, P= 0.0001). Conclusion: PMTCT interventions in the control of MTCT of HIV is effective. To eliminate MTCT of HIV, promoting PMTCT services must be encouraged.

Crossing iVRoad: A VR application for detecting unilateral visuospatial neglect in poststroke patients

This paper presents the immersive virtual reality (VR) application iVRoad for the detection of unilateral visuospatial neglect in right hemisphere poststroke patients. With our immersive VR tool, it is possible to perform realistic road crossing in a safe environment using a head-mounted display (HMD). We present and discuss the virtual environment (VE) for an upcoming study with neglect patients, a broad range of neurological patients and a healthy control group. Our aim is to determine whether extrapersonal neglect can be reliably diagnosed in the chronic phase using VR with the help of various measured values (task completion time, errors, head rotations, eye tracking).
Relaxation between t : lectrons and the Crystalline Lattice *

the computation scheme does not undergo any change. These expressions for the distribution function permit us to construct a theory of the equilibrium properties of the dipole crystals under con sideration. Numerical calculations and comparison with experiment, and also comparison with other theories which apply to the two very simple cases considered by us will be given in a subsequent paper. Separate consideration is necessary for the construction of a theory in the case of violation of the relation (32), while this case has the greatest interest. We hope in the near future to publish results which apply to this variant. For the second of the problems considered by us the considerations developed above can without essential change be applied for the purpose of constructing a semiclassical theory of ferromagnetic bodies without use of the "sphericalizing" approximation.
A Low-loss Coaxial Comb-line Filter Design and Implementation for Aircraft Autopilot FMCW Radar Altimeter

Pulse or FMCW altimeters are used for height or distance measurement. For both types, a radio frequency signal is sent and after few micro seconds the reflected signal from the ground or sea is received and then by signal analysis the height can be measured. Because of wide frequency bandwidth of mixer in receiver and for better sensitivity, frequency modulation, jamming and noise, a narrowband low insertion loss bandpass filter should be designed. In this paper a new structure 4 g  stepped impedance resonator (SIR) narrowband bandpass filter is proposed that has special specifications such as %4.5 tunable bandwidth (%3 up to %7), sharp and wide stopband frequency characteristic, less than 0.7 dB insertion loss in passband and more than 80 dB rejection in stopband. With new coaxial resonators the seven pole Chebychev bandpass filter is designed and fabricated with more than %15 frequency tuning capability. Good agreement between measured and simulated results validates this design process.
Pedestrian Detection in Driver Assistance Using SSD and PS-GAN

Pedestrian detection is a critical challenge in the field of general object detection, the performance of object detection has advanced with the development of deep learning. However, considerable improvement is still required for pedestrian detection, considering the differences in pedestrian wears, action, and posture. In the driver assistance system, it is necessary to further improve the intelligent pedestrian detection ability. We present a method based on the combination of SSD and GAN to improve the performance of pedestrian detection. Firstly, we assess the impact of different kinds of methods which can detect pedestrians based on SSD and optimize the detection for pedestrian characteristics. Secondly, we propose a novel network architecture, namely data synthesis PS-GAN to generate diverse pedestrian data for verifying the effectiveness of massive training data to SSD detector. Experimental results show that the proposed manners can improve the performance of pedestrian detection to some extent. At last, we use the pedestrian detector to simulate a specific application of motor vehicle assisted driving which would make the detector focus on specific pedestrians according to the velocity of the vehicle. The results establish the validity of the approach.
Identification of Explicit Features in Persian Comments

Recently, the approach towards mining various opinions on weblogs, forums and websites has gained attentions and interests of numerous researchers. In this regard, feature-based opinion mining has been extensively studied in English documents in order to identify implicit and explicit product features and relevant opinions. However, in case of texts written in Persian language, this task faces serious challenges. The objective of this research is to present an unsupervised method for feature-based opinion mining in Persian; an approach which does not require a labeled training dataset. The proposed method in this paper involves extracting explicit product features. Previous studies dealing with extraction of explicit features often focus on lexical roles of words; the approach which cannot be used in distinguishing between an adjective as a part of a noun or a sentiment word. In this study, in addition to lexical roles, syntactic roles are also considered to extract more relevant explicit features. The results demonstrate that the proposed method has got higher recall and precision values compared to prior studies. © 2019 JComSec. All rights reserved.
Prediction intervals for GLMs, GAMs, and some survival regression models

Abstract Consider a regression model, where D is a parametric distribution that depends on the vector of predictors . Generalized linear models, generalized additive models, and some survival regression models have this form. To obtain a prediction interval for a future value of the response variable Yf given a vector of predictors apply the non parametric shorth prediction interval to where the are independent and identically distributed from the distribution which is a consistent estimator of A second prediction interval modifies the shorth prediction interval to work after variable selection and if p > n where n is the sample size. Competing prediction intervals, when they exist, tend to be for one family of D (such as Poisson regression), tend to need and usually have not been proven to work after variable selection.
Human Platelet Rich Plasma Alleviates Liver Fibrosis in Murine Schistosomiasis Mansoni

Background: Schistosoma (S.) mansoni infection leads to hepatic fibrosis that may cause severe complications. Currently, there is no effective medication against schistosomiasis liver fibrosis. Aim of the Work: The aim of the present study was to evaluate the anti-fibrotic effects of human platelet rich plasma (PRP) against S. mansoni liver fibrosis in experimentally infected mice alone or in combination with praziquantel (PZQ). Materials and Methods: Seventy male BALB/c mice were divided into five mice groups; group I: Uninfected control (UC, n=10); group II: Infected, untreated (IU, n=15); group III: infected, treated 8 weeks post-infection (p.i.) with PZQ (PZQ, n=15); group IV: Infected, received 8 weeks p.i. PRP (PRP, n=15) and group V: Infected, treated 8 weeks p.i. with PZQ then received PRP (PZQ+PRP, n=15). All the mice were euthanized at 12 weeks p.i then parasitological, histopathological, immunohistochemical studies were done in addition to measuring of serum liver enzymes. Results: PZQ+PRP significantly reduced (p<0.001) the mean liver granuloma diameter by 71%, followed by PRP (51.2%) and then PZQ (33.8%). Also, PZQ+PRP achieved the highest reduction in the liver fibrosis (73.3%), whereas PRP achieved 63.8% reduction in the fibrosis and this was better than that revealed by PZQ (50.8%). On immunohistochemical examination of the liver sections, PZQ+PRP caused the least expression of alpha smooth muscle actin ( a -SMA), transforming growth factorβ 1 (TGF-β 1) and inducible nitric oxide synthase (iNOS), while it induced the strongest caspase3 expression, among the treated mice groups, in comparison to IU mice. PRP alone or in combination with PZQ significantly decreased serum liver enzymes comparing to IU mice. Conclusion: PZQ+PRP significantly reduced S. mansoni induced liver fibrosis in association with improving the liver enzymes. So, it is recommended to treat S. mansoni liver fibrosis by both PZQ and PRP, and this could be applicable in case of human liver fibrosis caused by schistosomiasis mansoni.
Impact of Global Change on the Availability of Fodder & Forage and Performance of Livestock in South Asia

Livestock systems worldwide contribute significantly to greenhouse gas emissions. There is a clear need to strengthen the base of infrastructure and expertise in greenhouse gas (GHG) monitoring from livestock systems in South Asia. This includes capacity for monitoring of CH4 eructed by livestock, N2O emitted from soils, and CH4 and N2O emitted from manures. Open circuit calorimetry (whole body chambers or hoods) are the best methods for monitoring methane eructed by stall fed livestock, while the SF6 tracer technique is most applicable to free ranging livestock. Whole barn chambers and micrometeorological methods are far more costly and technically intensive, and not applicable to individual livestock or statistical comparison of treatments. N2O from soils is most easily monitored using static soil cover chambers; although a host of more complex and costly methods have been employed. Similar techniques may be applied to monitoring manures as are applied to soil monitoring, with appropriate modifications depending on the manure characteristics. Modeling can be usefully employed to estimate GHG emissions associated with energy consumption, to strengthen results obtained by field monitoring, and to estimate total system GHG emissions. Details on the standard methods are presented. Successful application of methods requires that certain basic concepts, design details, and protocols be observed. From the point of view of cost and practicality, standard methods are recommended for application in South Asia. Introduction: Ruminant agriculture generates greenhouse gasses (GHGs) in the form of methane eructed from the rumen, methane and nitrous oxide emitted from stored manures, and nitrous oxide from soils where feed is grown, especially after fertilizing with livestock manures. Livestock systems contribute approximately 15% of direct methane emission worldwide. About 75% of this is expelled directly from digestive tracts, while the remainder is produced by stored manures (IPCC, 2001, Moss et al., 2000). Ruminant animals contribute the majority of this. Agriculture has been identified as a
CSR symbolic potential and business sustainability

Abstract This essay is an ethical reflection on the idea of corporate social responsibility (CSR) focusing on emphasizing its strategic position as the symbolic potential of business. As such, CSR is the reflection of business moral commitment to providing meaningful social activities, on the one hand, and, at the same time, intensifying ethical climate and ensuring long-lasting sustainability of the company. Three conditions are required to get realized such commitment: (i) the necessity of ensuring the quality of CSR programs; this can be satisfied by the Subject-Subject approach in the process of designing and performing CSR programs. (ii) Putting special concern on the long-lasting impacts of CSR programs on the community welfare. Blending community empowerment in every CSR programs would help realize better the concern. And, (iii) the necessity of the presence of ethical leadership in business. This would help institutionalize ethical values and hence preserve the sustainability of CSR as the symbolic potential of business. This will in turn help support further business sustainability.

Considerations for Supporting Homeless Adoslescents

Every year, there is over one million adolescents who face homelessness in the United States. Even with this rising number of homeless adolescents, various definitions of homeless adolescents currently exist. This paper will clearly define homelessness, in particular homeless adolescents, through the McKinney-Vento Act of 2001. In addition, the precipitating factors for school counselors to look for when working with adolescents who may be at-risk of facing homelessness will be delineated. Many different effects of homelessness will also be discussed, as well as engaged roles school counselors can assume to collaborate with other educators and community members by advocating and addressing homelessness at a local, state and federal level. Finally, a new collaborative effort that has been developed addresses and advocates for the needs of homeless adolescents and families is the Community Action Targeting Children who are Homeless (CATCH) program is presented. Overall, the CATCH program advocates for homeless adolescents social-emotional needs and developmental status through different levels of intervention.
