Ultrasound, X-ray, computed tomography and clinical tests for diagnosis of abdominal purpura in children: A retrospective study

Imaging modalities are not included in The European League Against Rheumatism, The Pediatric Rheumatology International Trials Organization and The Pediatric Rheumatology European Society 2010 criteria for the evaluation of abdominal purpura. The objective of the present study was to compare diagnostic parameters of ultrasound, X-ray and computed tomography (CT) for diagnosis of abdominal purpura considering the American College of Rheumatology (ACR) criteria as ‘reference standard’ in children with acute abdominal pain. Medical records of 215 children with acute abdominal pain were reviewed. Data regarding demographics and clinical characteristics, laboratory tests, X-ray, ultrasound findings, and computed tomographic images were collected and analyzed. Decision curve analysis was used for evaluation of the beneficial score for each diagnostic modality. Among diagnostic modalities, CT had the highest sensitivity (0.939); however, ultrasound findings had the highest accuracy (0.861) for diagnosis of abdominal purpura. Unlike X-ray and laboratory tests, ultrasound and CT were successful at detecting abdominal purpura when children had only colicky pain and were aged <20 years; however, occult blood stool test and granulocytes in the walls of small venules and arterioles (biopsy results) were negative. With respect to the ACR criteria, there were seven and three inconclusive results for ultrasound and CT, respectively. Abdominal ultrasound is an easy, non-invasive and safe method for the detection of abdominal purpura in children.
Automatic Sorting of Dwarf Minke Whale Underwater Images

A predictable aggregation of dwarf minke whales (Balaenoptera acutorostrata subspecies) occurs annually in the Australian waters of the northern Great Barrier Reef in June–July, which has been the subject of a long-term photo-identification study. Researchers from the Minke Whale Project (MWP) at James Cook University collect large volumes of underwater digital imagery each season (e.g., 1.8TB in 2018), much of which is contributed by citizen scientists. Manual processing and analysis of this quantity of data had become infeasible, and Convolutional Neural Networks (CNNs) offered a potential solution. Our study sought to design and train a CNN that could detect whales from video footage in complex near-surface underwater surroundings and differentiate the whales from people, boats and recreational gear. We modified known classification CNNs to localise whales in video frames and digital still images. The required high classification accuracy was achieved by discovering an effective negative-labelling training technique. This resulted in a less than 1% false-positive classification rate and below 0.1% false-negative rate. The final operation-version CNN-pipeline processed all videos (with the interval of 10 frames) in approximately four days (running on two GPUs) delivering 1.95 million sorted images.

High-fidelity View Synthesis for Light Field Imaging With Extended Pseudo 4DCNN

Multi-view properties of light field (LF) imaging enable exciting applications such as auto-refocusing, depth estimation and 3D reconstruction. However, limited angular resolution has become the main bottleneck of microlens-based plenoptic cameras towards more practical vision applications. Existing view synthesis methods mainly break the task into two steps, i.e. depth estimating and view warping, which are usually inefficient and produce artifacts over depth ambiguities. We have proposed an end-to-end deep learning framework named Pseudo 4DCNN to solve these problems in a conference paper. Rethinking on the overall paradigm, we further extend pseudo 4DCNN and propose a novel loss function which is applicable for all tasks of light field reconstruction i.e. EPI Structure Preserving (ESP) loss function. This loss function is proposed to attenuate the blurry edges and artifacts caused by averaging effect of ${L_2}$ norm based loss function. Furthermore, the extended Pseudo 4DCNN is compared with recent state-of-the-art (SOTA) approaches on more publicly available light field databases, as well as self-captured light field biometrics and microscopy datasets. Experimental results demonstrate that the proposed framework can achieve better performances than vanilla Pseudo 4DCNN and other SOTA methods, especially in the terms of visual quality under occlusions. The source codes and self-collected datasets for reproducibility will be available online soon.
Underwater Tracking Based on the Sum-Product Algorithm Enhanced by a Neural Network Detections Classifier

The necessity of long-range underwater surveillance has strongly increased in the last decades, and low-frequency active sonar (LFAS) systems seem to fulfill this need. However, in littoral environments with shallow water LFAS may suffer from an elevate number of false alarms. In this context, the capability to distinguish between object-generated and clutter-generated detections is crucial. This paper describes a multiobject tracking framework based on the sum-product algorithm that exploits the information provided by a convolutional neural network that classifies the LFAS detections. The effectiveness of the proposed approach is demonstrated both in a simulated and in a real underwater scenario.
PREVALENCE OF INVASIVE PARTHENIUM WEED IN DISTRICT HAFIZABAD, PAKISTAN

Surveys of waste and grazing lands from 10 localities of the district Hafizabad were undertaken during March-April, 2009 to study the distribution of an alien invasive weed parthenium (Parthenium hysterophorus L.) in comparison of the weeds of the area. A total of 67 weed species belonging to 25 angiospermic plant families were found growing in the district. Parthenium was found to be growing in nine out of ten studied sites exhibiting 90% prevalence. The absolute frequency of occurrence of parthenium was 51%. Out of 67 recorded weed species in the area, only 14 weeds showed absolute frequency of 50% or above including parthenium. Parthenium was found among the densely populated weed species with absolute density of 1.55. Only 7 weed species namely Ageratum conyzoides L. Cichorium intybus , Cirsium arvense (L.) Scop. , Sueda fruticosa Forsk. , Cenchrus pennisetiformis Hochest, Cynodon dactylon Pers. , Dicanthium annulatum Stapf. , and Rumex dentatus L in the studied area showed absolute density greater than parthenium. The present study concludes that parthenium is rapidly colonizing waste lands of district Hafizabad. Urgent efforst are necessary to control its further spread in the area.
Research of Vehicle Rear-End Collision Model considering Multiple Factors

The accuracy of the rear-end collision models is crucial for the early warning of potential traffic accident identification, and thus analyzes of the main factors influencing the rear-end collision relevant models is an active topic in the field. The previous studies have tried to determine the single factor influence on the rear-end collision model performance. Less attention was paid to exploit mutual influences on the model performance. To bridge the gap, we proposed an improved vehicle rear-end collision model by integrating varied factors which influence two parameters (i.e., response time and road adhesion coefficient). The two parameters were solved with the integrated weighting and neural network models, respectively. After that we analyzed the relationship between varied factors and the minimum car-following distance. The research findings support both the theoretical and practical guidance for transportation regulations to release more reasonable minimum headway distance to enhance the roadway traffic safety.
Impact of Fixed Orthodontic Appliance with Diabetes Mellitus and Curcumin on the Body Weight of Experimental Rat

Background: This study aims to investigate the effect of diabetes mellitus, fixed orthodontic appliance and curcumin on the weight of experimental rats. Materials and Methods: Orthodontic tooth movement (OTM) take place in one side of a 'Split- mouth design study in 40 male Wistar albino rats, divided into four groups: non-diabetic group (n=10), non-diabetic and curcumin group (n=10), induced diabetes group (n=10) and induced diabetes and curcumin group (n=10). Diabetes type1 was induced and insulin was given throughout the experiments for controlling high blood glucose levels. Fixed orthodontic appliance with a closing-coil spring delivering 30 gm of force was used to move the first molar mesially while the incisors serving as an anchor unit. The weight of the animals was measured once a week till the day of scarifying the animal after 3weeks. Results: the results showed that all groups suffered from an intense weight loss during the third week and concluded that fixed orthodontic appliance, diabetes mellitus and curcumin can be considered as causative factors. Conclusion: the study concluded that diabetes mellitus, orthodontic treatment and curcumin cause reduction of body weight in rats.
The relationships of technology readiness, perceived value, satisfaction, and continuance intention – A study of self-service technologies in Viet Nam

Technologies have changed the way of doing business remarkably. The marketplace is being replaced by market space, where almost all products/services are embodied in digital forms and delivered through information-based channels. As a result, this study attempts to investigate the determinants of marketspace marketing, particularly of self-service technologies. More specifically, the study examines the relationships among technology readiness, perceived value, customer satisfaction, and continuance intention in using self-service technologies. Data was collected through a questionnaire survey on 179 users who have had experience in using self-service technologies (including internet banking, airline ticket online booking, and tours online booking) in Ho Chi Minh City –Vietnam’s largest city. Partial least squares structural equation modeling (PLS-SEM) was used to analyze the data. The results show that all of the six hypotheses were empirically supported. Specifically, (1) Technology readiness has a strong positive influence on perceived value, customer satisfaction, and continuance intention; (2) Perceived value shows a moderate positive impact on satisfaction and continuance intention; (3) Satisfaction has a significant positive impact on continuance intention. In terms of theoretical contributions, this study proposed a value-based framework to predict continuance intention and conceptualized technology readiness as a second-order formative construct, which better represents the content of the construct originally developed by Parasuraman (2000). In terms of managerial implications, marketing managers should pay special attention to TR when making decisions such as launching new SSTs, segmenting customers, or boosting customers’ TR.
Finite Element Simulation of Prosthetic Foot Adaptation to Mediolateral-Angled Cross-Slopes

ABSTRACT Introduction Balance, functional mobility, satisfaction with participation, residual limb comfort, and falls are persistent problems for people with lower-limb amputations (LLAs). Limited mediolateral accommodation of foot prostheses to cross-slope and uneven ground has been suggested to contribute to these problems. The purpose of this study is to examine how variations of prosthetic foot stiffness, width, and split toes alter mediolateral and vertical displacement, forward velocity, and ground-foot orientation during the stance phase of gait on cross-slopes using finite element computer simulation. Materials and Methods Model construction (material data, geometry, and mesh) and simulations were performed using Ansys LS Dyna. Durawalk foot geometry was used as the base model. Variations included cross-slope angle (5° increments from 10° to −10°), foot stiffness, body mass, foot width, and number of splits. Lateral deviation (millimeter), vertical displacement (millimeter), and change in forward velocity (% of initial) were obtained from the proximal pylon. Foot contact was measured as a percent of the base model foot width. Results For a given foot stiffness, mediolateral displacement, inferior vertical displacement, and forward velocity increased with increased cross-slope. Reduced foot stiffness decreased mediolateral displacement and increased foot contact, inferior vertical displacement, and forward velocity on cross-slopes. Wider foot design increased foot contact but increased mediolateral displacement on cross-slopes. Single- and double-split toes creating two or three cantilever springs improved foot contact and reduced mediolateral displacement compared with full-toe variations. Conclusions For full-width foot variations of stiffness, body mass, and width, properties that enabled maintenance of forward velocity during flat-ground walking gait resulted in mixed effectiveness on cross-slopes. Reducing foot stiffness resulted in deformation of the foot on cross-slopes, which reduced mediolateral displacement but increased forward velocity and vertical displacement. Increasing foot stiffness maintained vertical position and forward velocity but reduced foot contact and increased mediolateral displacement. Full-length splits of the foot into two or three cantilever springs resulted in less mediolateral displacement and improved foot contact. Full-length splits reduced performance changes from flat ground to cross-slopes compared with full-width prosthetic feet. Future studies will be necessary to determine which variations are optimal and if these results are sufficient for comfort, skin integrity, and performance for people with LLA who use prosthetic feet.

Barriers to exclusive breast feeding, the missing links: a cross sectional study from Puducherry, India

Background: Breast milk, the first natural food for a new-born, provides all the energy and essential nutrients an infant requires for the first 6 months of life. The NHFS -4 survey shows only 45.5% of children are exclusively breastfed (EBF) in Puducherry. This study aims at assessing the socio-demographic characteristics associated with exclusive breastfeeding in a tertiary hospital in Puducherry and identify the barriers in the promotion of exclusive breastfeeding. Methods: Community-based cross-sectional study at a tertiary hospital in Puducherry. Sample size: 115 mothers of 6 months to 2-year-old children, born term gestation with a birth weight of >2.5 kg, attending the Paediatric OPD. Questionnaire-based study comprising of socio-demographic and parameters pertaining to exclusive breast-feeding. Results: Only 44.3% of the mothers have exclusively breastfed in the first 6 months. Shorter duration of spacing between births and caesarean section had significant negative association with exclusive breast-feeding. Most of the mothers received postnatal counselling on breast-feeding (94%) of which 58% were by health care personnel. Despite that, only a sixth (19%) of them were well versed with proper breastfeeding techniques. Poor secretion (45.3%), sore/inverted nipple (23.5%) amounted to the most common of the barriers. Among working mothers, 42.9% attributed their jobs as the cause for early weaning. Conclusions: The prevalence of exclusive breastfeeding is still low even among a literate study group. There were no significant association with socio-demographic factors found, but lacunae were identified. A more objective postnatal counselling to mothers involving their caregivers may improve the current scenario.
Effects of circular trailing edge with the dimple on flow separation of NACA S1210 hydrofoil

Flow separation over a hydrofoil affects its hydrodynamic performance and ultimately reduces the power production of a turbine. Therefore, the different flow control methods have been proposed by the researchers to overcome these challenges. In this study, the combined effects of circular trailing edge with dimple have been investigated numerically on NACA S1210 hydrofoil to control the flow separation of the hydrofoil. The results showed that the coupled effects of the dimple and circular trailing edge modification appeared effective compared to baseline hydrofoil at a wide range of angles of attack. Maximum lift coefficient increments are 9 and 12% at an angle of attack of 10° and 12°, respectively, for circular trailing edge hydrofoil. The maximum increase of glide ratio for the coupled effect (circular trailing edge with outward dimple) is approximately 114% at an angle of attack of 12°. The outcome will be advantageous to design a proper blade profile for horizontal axis current turbines.
Sustainable Knowledge Investment Increases Employment and GDP in the Spanish Agricultural Sector More Than Other Investments

Investment in every type of asset increases GDP and net employment differently. This paper compares the effect produced by a permanent unitary shock in Sustainable Knowledge for the Primary Sector (SKPS) on the Spanish employment and GDP growth with the effect produced by the other fourteen capital stock types. The methodology used is a Vector Error Correction Model (VECM), where the complementary capital can affect SKPS instantaneously. The results suggest that SKPS produces the second-highest, short and long-term effects on both labor and production, per Euro invested; moreover, the investment of 4.3 thousand euros is retrieved in the first year and increases net employment in one person after four years. Accordingly, the 5 million Euro Budget to invest in sustainable machinery and processing techniques increases net employment by 827 employees.
Defining species boundaries in the genus Phytophthora: the case of Phytophthora andina A response to ‘Phytophthora andina sp. nov., a newly identified heterothallic pathogen of solanaceous hosts in the Andean highlands’ (Oliva et al., 2010)

Phytophthora is a genus comprising upwards of 100 species. The most recent phylogeny of the genus was inferred from seven nuclear genes (Blair et al., 2008) and was subdivided into 10 well-defined clades that are concordant with the morphology-based Waterhouse criteria (Waterhouse, 1963; Kroon, 2010). The description of new species in this genus has traditionally been based on morphological characters, ecology, geography and host specialization. Although these traits are useful in the nomenclatural recognition of different species, they are not necessarily correlated to their evolutionary history and thus should not be used alone as characters to define new species. It is now routine that new Phytophthora species descriptions also include a detailed phylogenetic analysis typically based on several loci. In an evolutionary context, reproductive isolation of a species from other close relatives is a fundamental requirement of the biological species concept (Mayr, 1942). The use of molecular markers, traditionally the nuclear internal transcribed spacer (ITS) region, has allowed recognition of species complexes such as P. citricola and P. megasperma. In species complexes the definition of species boundaries is difficult. When is a species in a lineage differentiated enough to be considered as a separate one (Mishler, 1985; Avise & Ball, 1990)? We believe that careful analysis of several nuclear and mitochondrial loci is needed to support the definition of species boundaries. Here we examine problems of defining species boundaries using the example of the recently proposed new species, Phytophthora andina.
Revised checklist of benthic marine macroalgae and seagrasses of Guam and Micronesia.

We have compiled the new records and nomenclatural changes since Tsuda & Wray's 1977 checklist and Tsuda's 1981a addendum. There are now 653 species of benthic marine algae reported from Micronesia: 85 species of Cyanophyta, 324 Rhodophyta, 58 Heterokontophyta (including 54 Phaeophyceae), and 186 Chlorophyta. We document here 40 new records for Guam. The total for Guam is now 237 species: 26 Cyanophyta, 109 Rhodophyta, 31 Heterokontophyta (including 27 Phaeophyceae), and 71 Chlorophyta. We have included 3 Pelagophyceae and 1 Bacillariophyceae (diatom) that form macroscopic colonies, as well as the 10 species of seagrasses (Magnoliophyta) that occur in the region.
