Siamese Network for RGB-D Salient Object Detection and Beyond

Existing RGB-D salient object detection (SOD) models usually treat RGB and depth as independent information and design separate networks for feature extraction from each. Such schemes can easily be constrained by a limited amount of training data or over-reliance on an elaborately designed training process. Inspired by the observation that RGB and depth modalities actually present certain commonality in distinguishing salient objects, a novel joint learning and densely cooperative fusion (<italic/>JL-DCF<italic/>) architecture is designed to learn from both RGB and depth inputs through a shared network backbone, known as the <italic>Siamese architecture</italic>. In this paper, we propose two effective components: joint learning (JL), and densely cooperative fusion (DCF). The JL module provides robust saliency feature learning by exploiting cross-modal commonality via a Siamese network, while the DCF module is introduced for complementary feature discovery. Comprehensive experiments using five popular metrics show that the designed framework yields a robust RGB-D saliency detector with good generalization. As a result, JL-DCF significantly advances the state-of-the-art models by an average of <inline-formula><tex-math notation="LaTeX">$\sim 2.0\%$</tex-math><alternatives><mml:math><mml:mrow><mml:mo>∼</mml:mo><mml:mn>2</mml:mn><mml:mo>. </mml:mo><mml:mn>0</mml:mn><mml:mo>%</mml:mo></mml:mrow></mml:math><inline-graphic xlink:href="fan-ieq1-3073689.gif"/></alternatives></inline-formula> (max F-measure) across seven challenging datasets. In addition, we show that <italic/>JL-DCF<italic/> is readily applicable to other related multi-modal detection tasks, including RGB-T (thermal infrared) SOD and video SOD, achieving comparable or even better performance against state-of-the-art methods. We also link <italic/>JL-DCF<italic/> to the RGB-D semantic segmentation field, showing its capability of outperforming several semantic segmentation models on the task of RGB-D SOD. These facts further confirm that the proposed framework could offer a potential solution for various applications and provide more insight into the cross-modal complementarity task.
Sum-Rate Maximization for Intelligent Reflecting Surface Assisted Terahertz Communications

In this paper, an intelligent reflecting surface (IRS) is deployed to assist the terahertz (THz) communications. The sum-rate of user equipments (UEs) is maximized while guaranteeing the rate requirement of each UE. A block coordinate searching (BCS) algorithm is proposed to jointly optimize the IRS's coordinates, phase shifts, THz sub-bands allocation and power control. Specifically, the relaxation with penalties based (RPB) algorithm is developed to guarantee the feasibility of obtained IRS's coordinates and the monotonicity of objective value. In addition, to optimize the IRS's phase shifts, the sub-gradient descent (SGD) algorithm is proposed, where the IRS phase shifts are formulated as closed-form expressions with introduced pricing factors. Simulation results show that the proposed scheme can significantly enhance system performance.
An Empirical Study of In-App Advertising Issues Based on Large Scale App Review Analysis

In-app advertising closely relates to app revenue. Reckless ad integration could adversely impact app reliability and user experience, leading to loss of income. It is very challenging to balance the ad revenue and user experience for app developers. In this paper, we present a large-scale analysis on ad-related user feedback. The large user feedback data from App Store and Google Play allow us to summarize ad-related app issues comprehensively and thus provide practical ad integration strategies for developers. We first define common ad issues by manually labeling a statistically representative sample of ad-related feedback, and then build an automatic classifier to categorize ad-related feedback. We study the relations between different ad issues and user ratings to identify the ad issues poorly scored by users. We also explore the fix durations of ad issues across platforms for extracting insights into prioritizing ad issues for ad maintenance. We summarize 15 types of ad issues by manually annotating 903/36,309 ad-related user reviews. From a statistical analysis of 36,309 ad-related reviews, we find that users care most about the number of unique ads and ad display frequency during usage. Besides, users tend to give relatively lower ratings when they report the security and notification related issues. Regarding different platforms, we observe that the distributions of ad issues are significantly different between App Store and Google Play. Moreover, some ad issue types are addressed more quickly by developers than other ad issues. We believe the findings we discovered can benefit app developers towards balancing ad revenue and user experience while ensuring app reliability.
Respiratory Health Effects of Occupational Exposure to Hazards of Public Waste in Cross River, Nigeria

Public waste disposal workers in Cross River State do not take precautionary measures and are exposed to waste that generates gases, dust and microorganisms. Spirometry and respiratory symptoms in public waste workers in Cross River state, Nigeria was studied with the aid of a spirometer and questionnaire respectively. Dust and gases (NO2, SO2, H2S and FL) emitted from the vicinity were also studied. Two hundred and forty (240) male subjects were used for the study comprising 120 test and 120 control subjects with similar anthropometric parameters. Results showed that the mean FVC (Liters) in the test subjects was significantly reduced (p<0.01) compared to the control. Mean FEV1 (liter) of the test group was significantly lower (p<0.001) than control. Result for FEV1% (Liters) and PEFR (L/min) in the test subjects was not significantly different compared to control. Percentage of oxygen saturation (SPO2%) in both control and test subjects were not significantly different. Dust levels (mg/m3) in the test sites was significantly higher (p<0.001) than in control sites. SO2, NO2 and H2S were significantly higher in test sites compared to control (p<0.05-p<0.01). There was a higher incidence of respiratory symptoms such as productive cough, sneezing etc in public waste workers. Public waste workers had a restrictive pattern of impairment caused likely by significantly high dust levels with SO2 level which exceeded the ambient levels as documented by the Federal Ministry of Environment in Nigeria

Study of breastfeeding practices amongst PNC mothers in urban slum areas in Solapur city , Maharashtra

Since 1993, WHO’s effort to improve infant and young child nutrition have focused on promoting breastfeeding. It is estimated that suboptimal breastfeeding especially non-exclusive in first six months of life results in 1.4 million deaths and 10% of the disease burden in children younger than five year. The objective of present study was to know the various breastfeeding practices and knowledge in lactating PNC mothers. In this Materials and methods were a cross sectional observational study was carried out over the period of Jan 2012 to Dec 2012. Total of 200 PNC mothers who were enrolled in the anganwadi were selected for the study. The Results were Out of total, 14% mothers received advice on breastfeeding during ANC. 6% initiated breastfeeding within 1 hour. 37% mothers had given prelacteals. 22% mothers discarded colostrum. 55% babies received demand feeding. Breastfeeding feeding practices were appropriate in 64% of women. In Conclusion Very few mothers initiated breastfeeding at correct time. Wrong customs like giving prelacteals and discarding colostrum is still practiced in the society. Though the majority of mothers had right knowledge but breastfeeding practices was not appropriate. Very few mothers received advised regarding breastfeeding from the trained personnel.
Thyroid Dysfunction in Diabetes Mellitus: A Cross-Sectional Study from a Western State in India

DOI: 10.21276/sjm.2018. 3.8. 3 Abstract: Thyroid Dysfunction (TD) and Diabetes Mellitus (DM) are often found associated in the same patient and TD may affect the metabolic control of DM. TD is more prevalent in diabetics than in general population. The current study investigates the prevalence of TD in patients with DM, and explores its correlation with age, sex, type and duration of DM, and glycemic control (HbA1c levels). This was an observational, crosssectional study of 212 patients with DM. All patients had undergone routine clinical and laboratory evaluations as per the standard clinical care. Medical data was collected and analyzed using Epi Info V3.5. 4. Among the 212 DM patients evaluated, the overall prevalence of TD was 24.52%. The overall prevalence of TD was less in type-2 DM (T2DM; 24.46%) as compared to type-1 DM (T1DM; 37.5%); and slightly more in females (31.94%) as compared to males (28.65%). The prevalence of TD was high in the middle age (41-60 years) group (52.17%) as compared to other age groups. Subclinical hypothyroidism (SCH) was the most common type of TD (11.79%) with maximum prevalence (50%) in T2DM. Patients with DM reported a high prevalence rate of 24.52% for TD. Patients between 41-60 years of age had higher prevalence of TD. Prevalence was slightly more in more in females as compared to males. Our data suggests for screening of DM patients for risk of TD that might be helpful in secondary and primary prevention and possible better metabolic control.

Assessment of Some Qualities of Two banana Cultivars during Storage

DOI: 10.21276/haya.2018. 3.9. 3 Abstract: In an attempt to increase the shelf life of banana for some days prior to processing and also enhance the nutritional quality of banana, two banana cultivars (Musa acuminata and Musa sapientus) were stored using three different storage media (banana leaves, fabric cloths and a clay pot). banana bunches were cut into fingers and differently wrapped in each storage medium and stored at ambient condition of 28±2°C and 79±3% relative humidity, while unwrapped bunches were placed on the laboratory shelf as control. Samples were analyzed for sugar, starch, moisture, ash, brix, pH, TTA, vitamin C and minerals on day 0, 5, 7 and 10. Sugar content of banana ranged from 4.55 to 17.83%, with the highest value observed in sample stored in clay pot. The moisture content ranged from 59.13 to 78.51%, ash ranged from 1.24 to 1.72% and brix ranged from 3.38 to 14.59 degree brix. Significant increase was observed in pH, TTA, vitamin C, potassium, phosphorus, iron and zinc during storage while starch decreased as storage period progressed. Samples stored in the clay pot retained qualitative properties more than those stored on shelf at ambient condition.
Deconvolutional artificial neural network models for large eddy simulation of turbulence

Deconvolutional artificial neural network (DANN) models are developed for subgrid-scale (SGS) stress in large eddy simulation (LES) of turbulence. The filtered velocities at different spatial points are used as input features of the DANN models to reconstruct the unfiltered velocity. The grid width of the DANN models is chosen to be smaller than the filter width, in order to accurately model the effects of SGS dynamics. The DANN models can predict the SGS stress more accurately than the conventional approximate deconvolution method (ADM) and velocity gradient model (VGM) in a prior study: the correlation coefficients can be made larger than 99\% and the relative errors can be made less than 15\% for the DANN model. In an a posteriori study, a comprehensive comparison of the DANN model, the implicit large eddy simulation (ILES), the dynamic Smagorinsky model (DSM), and the dynamic mixed model (DMM) shows that: the DANN model is superior to the ILES, DSM, and DMM models in the prediction of the velocity spectrum, various statistics of velocity and the instantaneous coherent structures without increasing the considerable computational cost. Besides, the trained DANN models without any fine-tuning can predict the velocity statistics well for different filter widths. These results indicate that the DANN framework with consideration of SGS spatial features is a promising approach to develop advanced SGS models in the LES of turbulence.
Impact of Giardiasis on Plasma Protein profile of infected children

Giardia is a common protozoan parasite infecting children in developing countries and is known to result protein loss in infected children. The objective of this study was to assess the association of plasma protein profile with Giardiasis among children in district Anantnag of Kashmir valley. The study included 268 children aged 5-15 years belonging to both the genders. Stool samples collected from children were screened for Giardia infection and blood samples were analysed to estimate plasma protein, albumin and globulin levels. The results showed a significant decrease in mean values of total protein between infected and uninfected children from 6.71±0.96 to 7.01±0.98. The mean values of albumin also showed a decrease in their values between infected and uninfected children from 3.7±0.45 to 4.21±0.51 and that of globulin showed an increase in mean values from 3.01±0.91 to 2.8±0.58 between infected and uninfected children. However the difference was statistically insignificant (p> 0.05).

Oral Health Behaviour and its Determinants among Dental, Medical and Nursing Students in a Tertiary Institution in Lagos State, Nigeria

Background: Oral health entails practicing and maintenance of good oral hygiene. It is an integral part of general health. Aim: To determine the oral health behavior among dental, medical and nursing students of the Lagos State University College of Medicine, Ikeja Lagos. Nigeria. Materials and Methods: The survey was conducted among dental, medical and nursing students of Lagos State University College of Medicine, Ikeja, using a self-administered structured questionnaire, which assessed their oral health attitude and practices. The obtained data was analyzed using the Statistical Package for the Social Sciences version 21 software. Results: One hundred and thirty participated in the study. More than twenty-eight percent (28.5%) brush twice a day, 27.7% use dental floss regularly, and only 47.7% use water to rinse after meals. About 56.9% of the medical students have never been to a dentist. A few, 7.7% have undertaken the every 6 months dental visits and 77.7% agreed that oral hygiene was necessary for good general health. The study also showed that female students (both dental and medical) showed better oral health practices than male students. Conclusion: Although dental students exhibited better practice towards oral health, but there was a lack of adequate attitude among them. Further emphasis on oral health is necessary in undergraduate training to improve the oral health attitude and practice among dental, medical and nursing students as they will act as role models for oral health education among individuals and community at large.
Making Decisions under Model Misspecification

We use decision theory to confront uncertainty that is sufficiently broad to incorporate "models as approximations. " We presume the existence of a featured collection of what we call "structured models" that have explicit substantive motivations. The decision maker confronts uncertainty through the lens of these models, but also views these models as simplifications, and hence, as misspecified. We extend min-max analysis under model ambiguity to incorporate the uncertainty induced by acknowledging that the models used in decision-making are simplified approximations. Formally, we provide an axiomatic rationale for a decision criterion that incorporates model misspecification concerns.
Efficacy of some new fungicides in controlling purple blotch of onion under Punjab conditions

Nine fungicides viz. Nativo -75WG (trifloxystrobin 25% + tebuconazole 50%), Folicur 250 EC (tebuconazole), Flint 50WG (trifloxystrobin), Score 25 EC (difenoconazole), Tilt 25 EC (propiconazole), Contaf 5EC (hexaconazole), Indofil M – 45 (mancozeb 75 WP), Blitox 50 WP (copper oxychloride) and Antracol 70 WP (propineb) were evaluated for their effectiveness under in vitro and in vivo conditions against Alternaria porri – an incitant of purple blotch of onion. All fungicides significantly inhibited mycelial growth of the pathogen. Score 25 EC and Nativo-75WG were found to be most effective as these completely inhibited the mycelial growth at 0.1 per cent. Out of these nine fungicides, highest disease control (85.0%) and seed yield were recorded in foliar application of nativo – 75 WG followed by Folicur 250 EC and Tilt 25 EC. Other fungicides were comparatively less effective in controlling the disease under field conditions.

Design Optimization for Wear in Pin Joints of Backhoe Systems

The design of a backhoe system which experiences wear at various joints of the system is presented. The backhoe system is designed so that the frequency of maintenance due to wear at the joints is reduced. This is achieved by redesigning the main joints of the system such that the maximum allowable wear for all joints is attain in approximately the same number of operating cycles. This would allow for all the concerned joints to be refurbished in a single maintenance session rather than requiring various sessions for the repair of each joint. The design problem is restated as an optimization problem that involves minimizing the difference in the number of cycles required by the various wearing joints of the systems to reach the maximum allowable wear. The size of the joint (joint depth) together with the joint component wear coefficient are taken as the design variables. The immense computational burden associated with wear analysis, is managed through the use of surrogate models to represent the relationship between the design variables and the number cycles required to attain the maximum allowable wear. Subsequently a surrogate base optimization is performed in order to determine the optimum design.
The Historic Fire Return Interval and the Ecological Effects of Fire Suppression on Montane Longleaf Pine Dominated Ecosystems in Northwestern Georgia

Longleaf pine ecosystems have experienced pronounced declines across the southeastern United States since Euro-American settlement took place in the late 19th century. These declines were primarily caused by federal fire suppression policies implemented in the 1920’s, in combination with resource harvesting and land use conversion. In an absence of fire, tree species composition of frequently burned xeric ecosystems progressively becomes more mesic and fire-intolerant (i.e. mesophication). The change in the species composition and historic fire frequency of a montane longleaf pine ecosystem located in Sheffield Wildlife Management Area (WMA), Paulding County, Georgia was investigated. The change in forest composition was measured using modern vegetation surveys and historic “witness tree” vegetation data obtained from a georeferenced 1832 Georgia Land Lottery Survey map. The historic fire return interval was estimated using remnant longleaf stumps and dendrochronological techniques. Results from -tests indicated the modern forest is significantly more mesic and fire-intolerant than the historic forest (p < 0.0001), with no statistically significant difference in species composition between northand south-facing slopes. A chronology for longleaf pine was constructed using 214 cores from extant longleaf pine and 14 relict stumps found in Sheffield WMA. Using fire scars found in seven of the preserved stumps, the historic mean fire return interval was calculated to be 5.5-years with a median return interval of 3.5-years. It was concluded that mesophication has occurred in Sheffield WMA since Euro-American settlement, and that fires were historically present in the forest but likely of low intensity and fragmented across the landscape.
