Context-aware MDNet for target tracking in UAV remote sensing videos

ABSTRACT With the maturity and popularity of unmanned aerial vehicle (UAV) technology, remote sensing target tracking in the aerial videos from UAVs has drawn much attention in recent years. Given that UAV aerial video has low resolution, multiple similar disruptors and rapid perspective changes, and the main tracking methods in this research field generally have low tracking performance and timeliness, we propose a remote sensing target tracking method for UAV aerial video based on a context-aware multi-domain convolutional neural network (CAMD). First, in the design of the tracking network structure, we fuse multiple convolutional layers using residual connections to boost the effectiveness of regression learning. Then, in the offline pretraining stage, a Rotation Adversarial Autoencoders (RAAE) was adopted to generate typical easily confused negative samples for enhancing the capacity to distinguish between targets and the background interference. Finally, when the estimated target score was in the ‘fuzzy interval’, we introduced a response-adaptive context-aware correlation filter (RA-CACF) module into our network architecture to improve the tracking performance. Qualitative and quantitative evaluations using public and homemade hard datasets demonstrate that the proposed method can achieve high accuracy and efficiency results compared to state-of-the-art trackers.
The Impact of Diurnal Preferences on Customer Satisfaction, Word of Mouth and Repurchasing: A Study in Indian College Online Shoppers

The importance of positive word of mouth (WOM) and repurchasing in competitive online retail environments demands their further study. Although customer satisfaction has been found to drive positive WOM and repurchasing, limited research has explored what type of customers feel more satisfied with online shopping. It was anticipated that the convenient nature of online shopping would better match the conscientious personality traits of customers with earlier sleep and wake times. Data collected from 334 Indian college students participating in this study using a snowball sampling method were analysed by multiple regression. As hypothesised, based on self-congruency theory, customers with earlier sleep and wake times were found to feel more satisfied with online shopping, which in turn enhanced their positive WOM and increased repurchase intention. Theoretical and managerial implications are discussed.
WE-NDBI-A new index for mapping urban built-up areas from GF-1 WFV images

ABSTRACT Recently, China has witnessed rapid development of high-resolution imaging satellites, with remote sensing images from satellites being applied extensively in social and economic sectors. The normalized difference built-up index (NDBI) was first used to extract urban built-up areas from TM/ETM+ image data. After successful launch of the Landsat-8 satellite, modifications have been made to the NDBI approach (BBIOLI approach) for mapping urban built-up areas from operational land imager (OLI) data with higher accuracy. However, experiments showed that the BBIOLI approach is not very suitable for Chinese high-resolution satellite image data. This study firstly analysed the spectral curves of ground objects generated by the GF-1 satellite and then proposes an innovative WE-NDBI approach to mapping urban built-up in the study area, i.e. large counties located in Xichang. The experimental results demonstrate an overall accuracy of 91.4%. To compare the WE-NDBI and BBIOLI approaches, the latter was used to extract urban built-up areas from OLI data for the same study area, and the experimental accuracy is 77.0%. It is concluded that the WE-NDBI approach is more suitable for mapping urban built-up areas.
Relationship between social support and postpartum depression in women with preeclampsia

Introduction: Postpartum depression is the most important mood disorder. Social support has been known as one of the risk factor for postpartum depression. Since preeclamptic women are faced with unexpected perinatal complaints, they need to receive more support; therefore this study was performed with aim to evaluate the relationship between social support and postpartum depression in women with preeclampsia. Methods: This Correlational study was performed on 122 women with preeclampsia admitted in public and Tamin Ejtemaei Hospitls of Mashhad in 2013. Beck Depression Inventory II (BDI-II) was completed six weeks after delivery, and Social support Questionnaire was completed two and six weeks after delivery. Data was analyzed by SPSS software (version 16) using Pearson Correlation and Kruskal-Wallis tests. PResults: The mean social support score after two weeks of delivery was 34.1±1.39 and after six weeks of delivery 23.3±1.04. There was significant relationship between social support 2 weeks after delivery with social support 6 weeks after delivery (P=0.001). Mean depression score was 11.1 ± 5.5. There was positive significant relationship between social support score 2 weeks (p=0.01) and 6 weeks (p=0.02) after delivery with depression 6 weeks after delivery. Conclusion: There was positive correlation between social support and postpartum depression. Depression increased by increasing the postpartum social support.
Assessment of Students’ Attitude towards Test-Taking in Secondary Schools in Afikpo Education Zone Ebonyi State, Nigeria

Assessment of students’ attitudes towards test-taking in secondary schools in Afikpo Education Zone of Ebonyi State, Nigeria was the main thrust of this study. The study was guided by four null hypotheses in line with the ex-post facto research design. Proportionate stratified random sampling technique was employed in selecting a sample 1,276 respondents from a population of 12,763 students distributed across 43 public and 71 private secondary schools in the study area. Students’ Attitudes Towards Test-Taking Questionnaire (SATTQ) with Cronbach's alpha reliability coefficient of . 893 was used for data collection. The null hypotheses were all tested at . 05 level of significance using population t-test and independent t-test statistical methods. Emerging findings showed that the level of students’ attitudes towards test-taking as an academic activity in secondary schools is significantly high. It was also shown that males students, students in urban and private schools significantly differ in their attitudes towards test-taking as an academic activity, from female students and students in rural and public secondary schools. Based on these findings, it was recommended, amongst others, that all students irrespective of gender, school type and school location should be properly counselled by both teachers and professional counsellors to develop positive attitudes towards taking tests in schools.
Diabetes: A slow poison to periodontia

Periodontitis is a common chronic inflammatory disease characterised by destruction of the supporting structures of the teeth, the periodontal ligament and alveolar bone. Epidemiological data confirm that diabetes is a major risk factor for periodontitis; susceptibility to periodontitis is increased by approximately threefold in people with diabetes. There is a clear relationship between degree of hyperglycaemia and severity of periodontitis. There is emerging evidence to support the existence of a two-way relationship between diabetes and periodontitis, with diabetes increasing the risk for periodontitis, and periodontal inflammation negatively affecting glycaemic control. Incidences of macro albuminuria and end-stage renal disease are increased two-fold and threefold, respectively, in diabetic individuals who also have severe periodontitis compared to diabetic individuals without severe periodontitis. Treatment of periodontitis is associated with HbA1c reductions of approximately 0.4%. Oral and periodontal health should be promoted as integral components of diabetes management.
Qualitative properties of spray‐dried blood fruit (
 
 Haematocarpus validus
 
 ) powder and its sorption isotherms

This work aims to study the qualitative properties of spray‐dried blood fruit powder (BFP) and to determine sorption isotherm through model fitting. The results showed that maximum yield was obtained with 30% maltodextrin (MD) at 150°C, having 1.57% moisture content and water activity (Aw) value of 0.3, respectively. Other characteristic properties of powder viz., hygroscopicity, bulk density, and solubility were also determined. Field‐emission scanning electron microscope (FESEM) was used for morphological and mineral compositional studies. Differential scanning calorimetry (DSC), X‐ray diffraction (XRD), and particle size distribution (PSD) of BFP were also evaluated. Moisture sorption isotherm (MSI) study of BFP resulted in good fitting with Peleg and GAB model. Therefore, it was concluded that superior quality BFP could be produced by a spray‐drying technique with 30% (w/w) MD and drying at 150°C temperature. PRACTICAL APPLICATIONS: Blood fruit (Haematocarpus validus) has important bioactive compounds, antioxidant properties, and some essential minerals, which play a significant role in human nutrition and traditional medicine for treating arthritis, jaundice, hypertension, cancer, etc. The processing of blood fruit juice/pulp by spray‐drying technique to produce powder is classified among the best processes resulting in better, superior‐quality powders that are ease for packaging, transportation, and with increased shelf life. MSI study helps in providing information regarding food processing operations related to drying, packaging, and storage.
NEW PARASITE OCCURRENCES IN Tamandua tetradactyla (PILOSA: MYRMECOPHAGIDAE) IN THE NORTHEAST OF BRAZIL: A PALEOPARASITOLOGICAL STUDY

Paleoparasitological studies have revealed parasite eggs in coprolites from humans and other animals, obtained in archaeological sites in the New and Old World. However, to date, the only parasite found in anteaters coprolites is Gigantorhynchus echinodiscus (Acanthocephala: Gigantorhynchidae). Here we present the results of paleoparasitological analysis of nine Tamandua tetradactyla coprolites, of layers dated from 8,870 and 3,190 years BP, collected in three archaeological sites: Toca dos Coqueiros, Toca da Passagem and Toca do Enoque, rock shelters located in the southeast of the Piaui state, Brazil. Each coprolite was rehydrated in 0.5% trisodium phosphate solution, homogenized with a glass rod for spontaneous sedimentation. A minimum of 20 slides of each sample was examined using light microscopy. Acanthocephalan eggs of three morphotypes were found: G. echinodiscus, Macracanthorhynchus hirudinaceus and Oligacanthorhynchus sp. Three morphotypes of Nematoda eggs and oocysts of cf. Entamoeba sp. were also found. The finding of G. echinodiscus , a species commonly reported in anteaters, reinforces the previous data and highlights the specificity and antiquity of this host-parasite interaction. This is the first finding of Oligacanthorhynchidae and Aspidoderidae parasites in T. tetradactyla. These findings evidence the need for more studies of the parasitic fauna of T. tetradactyla from both ancient and current times aiming to broaden the knowledge about the parasite diversity of this host and the evolutionary processes that led to these interactions.
A New Nonlinear Model-Based Fault Detection Method Using Mann–Whitney Test

A well-established theory of statistical inference enables the generation of statistical fault detection approaches. Previous works mainly focus on parametric tests that assume that probabilistic distributions of both healthy and faulty residuals can be parameterized. However, such assumptions may be quite limited for general nonlinear stochastic systems because those residuals are usually with unknown distribution. In this article, a new fault indicator is defined to replace the traditional residual, and a multistep fault detection method is developed via the standard Mann–Whitney (MW) test. Moreover, with weak assumptions on faults and systems, a one-step fault detection approach is proposed by means of the modified MW test. Finally, the effectiveness of the proposed fault detection method is verified by a simulation of three water tank system.
Morphological and biomechanical effects of annulus fibrosus injury and repair in an ovine cervical model

Tissue engineering repair of annulus fibrosus (AF) defects has the potential to prevent disability and pain from intervertebral disc (IVD) herniation and its progression to degeneration. Clinical translation of AF repair methods requires assessment in long‐term large animal models. An ovine AF injury model was developed using cervical spinal levels and a biopsy‐type AF defect to assess composite tissue engineering repair in 1‐month and 12‐month studies. The repair used a fibrin hydrogel crosslinked with genipin (FibGen) to seal defects, poly(trimethylene carbonate) (PTMC) scaffolds to replace lost AF tissue, and polyurethane membranes to prevent herniation. In the 1‐month study, PTMC scaffolds sealed with FibGen herniated with polyurethane membranes. When applied alone, FibGen integrated with the surrounding AF tissue without herniation, showing promise for long‐term studies. The 12‐month long‐term study used only FibGen which showed fibrous healing, biomaterial resorption and no obvious hydrogel‐related complications. However, the 2 mm biopsy punch injury condition also exhibited fibrotic healing at 12 months. Both untreated and FibGen treated groups showed equivalency with no detectable differences in histological grades of proteoglycans, cellular morphology, IVD structure and blood vessel formation, biomechanical properties including torque range and axial range of motion, Pfirrmann grade, IVD height, and quantitative scores of vertebral body changes from clinical computed tomography. The biopsy‐type injury caused endplate defects with a high prevalence of osteophytes in all groups and no nucleus herniation, indicating that the biopsy‐type injury requires further refinement, such as reduction to a slit‐type defect that could penetrate the full depth of the AF without damaging the endplate. Results demonstrate translational feasibility of FibGen for AF repair to seal AF defects, although future study with a more refined injury model is required to validate the efficacy of FibGen before translation.
Modeling and simulation of packet delivery rate in LTE-V network based on Markov chain

As one of the most promising communication technologies for vehicular networks, LTE-V has the advantages of wide coverage and a high transmission rate. 3GPP released the technical specification of LTE-V in March 2017, launching a spate of related research and industrialization. In this paper, we propose a communication model based on Markov process to evaluate the reliability of LTE-V. We derived the Packet Delivery Rate (PDR) of LTE-V based on the model. Moreover, we use Poisson process to model the distribution of vehicles on a highway, then combine the communication model with the vehicles' distribution to derive the PDR under this scenario. To verify the correctness of the proposed model, we established a simulation program on the MATLAB platform. By comparing the simulation results and the mathematical results, we found that simulation results are a very good fit for the model.
Students' Level of Financial Support Satisfaction Towards Their Daily Allowance

The purpose of this study is to determine the association on the students' level of financial support satisfaction and their daily allowance. The study used a quantitative approach-descriptive correlation using a self-made questionnaire that was answered by the senior high school student. The questionnaire mainly indicates the different ranges of school allowances and factors that influence the students' satisfaction. The weighted mean was used for computing the mean of the level of financial support satisfaction that students feel towards their daily allowance. It used the chi-square (x²) showing a significant association between students' financial support satisfaction and school allowance. Students' financial support satisfaction depends on the level of their daily allowance. Most of the students have the ranges forty-one to fifty pesos as their daily allowance. With this, students are satisfied with their daily school allowances. The students seem to have a peaceful mind in their financial life because of meeting financial obligations with fewer debts and liabilities. A student who manages well a financial resource leads to lesser debts and liabilities which tend to increase the level of financial support satisfaction. Furthermore, a financial support satisfied student is more confident, tolerant and less prone to stress for having improved individual well-being. In order to enhance budgeting skills and increased level of financial support satisfaction, this study suggests exploring more on the students who are making debts at an early age.
Proposing an integrated multi-criteria decision making approach to evaluate total quality management best practices in Malaysia hotel industry

Although numerous studies have focused on significant role of total quality management (TQM) in literature, little attention has been paid to using the multi-criteria decision making (MCDM) approach for analysis of TQM practices especially in the context of hospitality. The purpose of this study is to identify, prioritize and evaluate the TQM best practices in hotel industry by integrating the DEMATEL and ANP approaches. DEMATEL is employed to determine the interrelationships among the main practices and sub-practices while ANP is employed to examine the weights of main practices and sub-practices. The results of this study indicated that employee management had the first rank among other practices whereas the second and third rank encompass customer relationship management and leadership respectively. The findings of this study has shown guidance to practitioners to implement proper TQM in their organizations, effectively by using the suggested set of identified TQM best practices.
Prevalence of Lipodystrophy and Metabolic Syndrome at the Bertoua Day Hospital (East Region of Cameroon)

This cross-sectional study, carried out on a cohort of 568 HIV-infected patients followed at the Bertoua Day Hospital, aimed at assessing interventions used in the biomedical management of lipodystrophy and metabolic syndrome related to Antiretroviral therapy through the determination of their prevalence within this hospital. Patients had a minimum age of 18years old, a minimum duration of 2years antiretroviral therapy and all had given their informed consent to participate in the study. The mean duration of treatment for HIV patients with lipodystrophy cases was 68±9.2 months ranged from 24 to 136months and that for patients with metabolic syndrome cases was 46±8.5 months ranged from 24 to 151months (P value = 0.005). Lipodystrophy was observed with all the therapeutic protocols prescribed to HIVinfected patients in our study site. Lipodystrophy cases seen among HIV-infected patients using the d4T in their therapeutic protocol accounted for 41.11%, while those seen among HIV-infected patients using the AZT in their therapeutic protocol accounted for 51.57% (P <0.0001). Among HIVinfected patients using the NVP in their therapeutic protocol, we found 40.41% of lipodystrophy cases versus 28.23% of lipodystrophy cases among HIV-infected patients using the EFV in their therapeutic protocol (P value=0.01). Lipodystrophy cases related to the use of protease inhibitors in the therapeutic protocol accounted for 31.36%. The prevalence of metabolic syndrome cases was greatest among HIV-infected patients using protease inhibitors boosted by the ritonavir in their therapeutic protocol with 72.6% of cases (P value = 0.0003). The prevalence of metabolic syndrome cases determined in this study using the definition of the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) was 21.83% and that of lipodystrophy cases was 50.52% with 27.64% for lipoatrophy cases, 20.95% for lipohypertrophy cases and 1.93% for mixed syndrome cases (P value = 0.01). We also found 16.9% for lipodystrophy cases strongly associated with the metabolic syndrome among our HIV infected patients under HAART, with an Odds Ratio of 4.54 which was statistically significant with a confidence interval (CI) between 3.45 and 6.87 to 95% (P value = 0.03). In other words, these HIV infected patients were 4.54 times more likely to have a metabolic syndrome in the presence of lipodystrophy than in its absence.
Self-Regulated Learners in Voluntary Reading: The effects and Implications on EFL Reading Classes

This study was an attempt to investigate how self-regulated learning through voluntary reading (VR) affects EFL students’ reading comprehension. The researchers transform the self-regulation strategy that is usually done in class into self-checking voluntary reading card based on self-regulated learning (SRL). This research applied quasi- experimental with pre-test post-test control group design and to achieve the goal, 93 Indonesian EFL learners of a private university in East Java, Indonesia were chosen based on their performance on preliminary research treated as experimental and control group. The experimental group did VR activity and SRL strategies, and the control group received direct teaching. The data were analyzed using t- test and the result show ed that that the self-regulation through voluntary reading has a significant effect on students’ reading comprehension. This study implicitly reminds all EFL teachers in Indonesia to pay more attention to increase students’ self-regulation and to overcome the problems of independence, interest, habit in reading, and reading comprehension that the students face .
The evolutionary process of disruptive green innovation in China: evidence from the electric bicycle sector

ABSTRACT To achieve market-oriented green innovation, this paper explores the evolutionary path and driving factors of disruptive green innovation using an exploratory case study in which data are collected from the Luyuan electric bicycle company in China. The results reveal that disruptive green innovation is a dynamic and cumulative process. Entrepreneurship drives to open new markets. Competition within the industry drives to expand the new markets. Competition among industries and the subsidy policy drive to encroach on mainstream low-end markets. Technology and marketing drive to encroach on mainstream high-end markets. To scholars, our research contributes to the literature on green innovation by uncovering the application of disruptive innovation theory in the field of green innovation. To practitioners in firms, this evolutionary process can function as a frame of reference, enabling the tailoring of a market-oriented strategy for green innovation.
