Analysis in big data of satellite communication network based on machine learning algorithms

With the development of satellite communication network technology, the amount of data generated every day and the rate of data growth are amazing. These different types of data (not necessarily structured) contain rich information. Based on this, a satellite for machine learning is proposed. First, a correlation analysis model is established, and a machine learning method is applied to the data prediction analysis of the satellite communication network. The basic idea and application process of the AdaBoost‐BP algorithm are introduced in detail. Second, combined with the data features after dimensionality reduction processing, an efficient big data analysis model is trained. Third, in order to quickly locate the abnormal behavior of users under large‐scale data, an algorithm for quantifying abnormal behaviors of users based on satellite communication network log information and quickly detecting and analyzing big data is proposed. Finally, experimental verification is performed. The experimental results verify that the method can improve the big data analysis capability of satellite communication networks.

The gap junction blocker mefloquine impairs sleep-dependent declarative memory consolidation in humans

During sleep, the time-compressed replay of engrams acquired during preceding wakefulness drives memory consolidation. We demonstrate in healthy humans that direct electrical coupling between neurons via gap junctions, i.e., electrical synapses, contributes to this beneficial effect of sleep. Twenty male participants learned a declarative word-pair task and a procedural finger sequence tapping task before receiving the antimalarial mefloquine that is known to block electrical synapses. Retrieval was tested after a retention interval of approximately 20.5 hours that included nocturnal sleep. As predicted, mefloquine given before sleep impaired the retention of declarative memory. In contrast, this effect was absent in control groups, which stayed awake or received mefloquine after sleep. Irrespective of sleep or administration time, mefloquine enhanced retention performance on the procedural memory control task. We conclude that sleep-dependent processes relying on electrical neuronal coupling enable hippocampus-dependent declarative memory consolidation, presumably via time-compressed hippocampal replay of memory traces within sharp-wave/ripple complexes. The recruitment of this understudied form of neuronal information transfer may be necessary to achieve fast-paced memory reprocessing during sleep. Considering that drugs targeting neurochemical synapses have recently fallen short of substantially advancing the treatment of memory impairments in Alzheimer’s disease, schizophrenia or during normal aging, unraveling the contribution of gap junctions to sleep-dependent declarative memory formation can be expected to open new therapeutic avenues. Significance statement Sleep supports the strengthening and transformation of memory content via the active replay of previously encoded engrams. Surprisingly, blocking neurochemical synaptic transmission does not impair this function of sleep. Here we demonstrate that the direct electrical coupling between neurons via electrical synapses (gap junctions) is essential for the sleep-dependent formation of declarative memory, i.e., memory for episodes and facts. These findings are in line with the assumption that electrical synapses enable time-compressed neuronal firing patterns that emerge during sleep and drive declarative memory consolidation. Electrical synapses have so far not been linked to higher-order brain functions in humans; their contribution to sleep-dependent memory processing may provide a novel target for sleep-related clinical interventions.
The Significance of ST Segment Elevation in Lead aVR in Acute Anterior Myocardial Infarction

Background and purposes: lead aVR is an ignored lead in ECG, several studies showed that ST segment elevation in aVR may predict left main stem or 3 vessels disease, and so suggest that ST- elevation in patient with acute anterior myocardial infarction can be predictors for poor prognosis to confirm this; this study was conducted. Patients and Methods: 100 patients with acute anterior myocardial infarction were divided into two groups;1 st group had ST-segment elevation in lead aVR more than 0.5 mv and other group had no ST-segment elevation in lead aVR. All patients were followed in hospital staying through history, examination ,and investigations for risk factors of coronary vascular disease ,complications, and mortality. Results: ST-segment elevation in lead aVR was an important predictor of occurrence of adverse prognosis, it occurred more in patients with increasing age. Also it occurred more in patients with more risk factors for coronary vascular disease including diabetes mellitus ,hypertension ,smoking, and family history of ischemic heart disease. The study found that the occurrence of complications like shock, post myocardial infarction angina, heart failure, arrythmia were more in patients with ST-segment elevation in lead aVR . It was also found that mortality rate in patients with acute anterior myocardial infarction with ST-segment elevation in lead AVR of more than o.5 mv was higher than patients without ST-segment elevation in lead AVR. Conclusion:
Envelope Technique with Vestibular Releasing Incision - A Single Step Procedure for Root Coverage

Treatment of gingival recession in cases with a shallow vestibule and frenal pull are always challenging. Root coverage techniques have been continuously revised and simplified over the past few decades to obtain more predictable, esthetic, and stable results. Case Presentation: Two healthy patients with isolated Miller’s class I gingival recession, shallow vestibules, and frenal pull, were treated with an envelope technique using connective tissue grafts with vestibular releasing incisions in a single step procedure. Case Report Pathakota et al.; BJMMR, 19(6): xxx-xxx, 2017; Article no.BJMMR. 30585 2 Conclusion: The single step technique resulted predictable root coverage and increased width of keratinized gingiva. This technique promises to be a viable option for the treatment of isolated gingival recession associated with shallow vestibule and high frenal pull.
How Smart Tourism Embrace Blockchains and Smart Contracts

The purpose of the research is to investigate the implementation of blockchains (BCs) and smart contracts (SCs) in smart tourism. BCs and SCs in the context of tourism are underexplored. Data were collected and analysed from relevant secondary sources in extensive desktop research between January and August 2018. The results highlight some implemented examples of BCs and SCs in tourism and few that are still in probation phase. The findings are interesting for tourism policy-makers, professionals, academics and tourism suppliers who are interested in real value added of BCs and SCs in tourism.
Random Noise Attenuation of Common Offset Gathers Using Iteratively Reweighted $\ell_{2,1}$ Norm Minimization

Sparse representation (SR)-based denoising method attenuates random seismic noise trace-by-trace, which may not be able to employ the coherency between neighboring traces. To address this, we propose a multiple measurement vector (MMV)-based algorithm for robust denoising of multichannel seismic gathers. Seismic reflectors in common offset gather (COG) is characterized by horizontal events, which satisfy the common sparsity assumption, making it ideal for the MMV approach. <inline-formula> <tex-math notation="LaTeX">$\ell _{2,1}$ </tex-math></inline-formula>-norm regularization, which enforces two constraints on source matrix, i.e., temporal sparsity and the horizontal continuity, is then adopted in the MMV model to stabilize the lateral variation between channels. Besides, <inline-formula> <tex-math notation="LaTeX">$\ell _{2,1}$ </tex-math></inline-formula>-norm regularization provides a reasonable intrinsic structure to reduce the multisolution of the algorithm. Celebrating the strengths of iteratively reweighted (IR), we present a novel MMV algorithm, IR <inline-formula> <tex-math notation="LaTeX">$\ell _{2,1}$ </tex-math></inline-formula> norm minimization (IR-<inline-formula> <tex-math notation="LaTeX">$\ell _{2,1}$ </tex-math></inline-formula>), that further improves the performance. The formulated IR-<inline-formula> <tex-math notation="LaTeX">$\ell _{2,1}$ </tex-math></inline-formula> can be minimized by the alternating direction method of multipliers. Both synthetic and field data applications confirm the effectiveness of the proposed denoising method.

Non-invasive semi-quantitative and quantitative ultrasound imaging for diagnostics of knee osteoarthritis

Osteoarthritis (OA) is a common degenerative disease of synovial joints becoming more frequent with age. Pain, stiffness and functional disability caused by OA negatively affect the quality of individuals’ lives. In order to prevent the manifestation of symptoms and further OA progress, early diagnosis is essential. Ultrasonography has the potential to detect various abnormalities in the knee joint, however its place in clinical practice remains uncertain. The present study aimed to determine the diagnostic performance of the semi-quantitative wide-area ultrasound (US) scanning of knee femoral cartilage degeneration, osteophytes and meniscal extrusion using magnetic resonance imaging as the reference tool. Diagnostic ability of conventional radiography (CR) was also determined and the performances of both modalities compared. Subsequently, the association of structural US findings with knee pain and function was investigated. Finally, quantitative US image analysis focusing on detection and evaluation of subchondral bone integrity in early OA was developed. The US quantitative outcomes were compared with CR and arthroscopy. Tibio-femoral osteophytes, medial meniscal extrusion and medial femoral cartilage morphological degeneration were identified by US with better or at least comparable accuracy than by CR, in which joint space narrowing was used as a composite measure of cartilage damage and meniscal extrusion. The global femoral cartilage grade associated strongly with increased pain and disability. Site-specifically, especially medial cartilage degeneration and femoral lateral osteophytes were associated with increased pain and disability. Regarding the quantitative outcomes, significant increase in US intensity in the femoral subchondral bone depth 0.35–0.7 mm and decrease in intensity slope up to 0.7 mm depth were observed during radiographic or arthroscopic OA progression. Novel wide-area US scanning provides relevant additional diagnostic information on tissuespecific OA pathology not depicted by CR. US-detected changes of femoral cartilage and osteophytes are also associated with clinical symptoms. Consequently, the use of US as a complementary imaging tool along with CR may enable more accurate diagnostics of knee OA. Furthermore, developed quantitative US analysis is a promising tool for detection of femoral subchondral bone changes in knee OA.
Word Importance Modeling to Enhance Captions Generated by Automatic Speech Recognition for Deaf and Hard of Hearing Users

People who are deaf or hard-of-hearing (DHH) benefit from sign-language interpreting or live-captioning (with a human transcriptionist), to access spoken information. However, such services are not legally required, affordable, nor available in many settings, e.g., impromptu small-group meetings in the workplace or online video content that has not been professionally captioned. As Automatic Speech Recognition (ASR) systems improve in accuracy and speed, it is natural to investigate the use of these systems to assist DHH users in a variety of tasks. But, ASR systems are still not perfect, especially in realistic conversational settings, leading to the issue of trust and acceptance of these systems from the DHH community. To overcome these challenges, our work focuses on: (1) building metrics for accurately evaluating the quality of
Existence and a blow-up criterion of solution to the 3D compressible Navier-Stokes-Poisson equations with finite energy

We study the low-energy solutions to the 3D compressible Navier-Stokes-Poisson equations. We first obtain the existence of smooth solutions with small \begin{document}$ L^2 $\end{document} -norm and essentially bounded densities. No smallness assumption is imposed on the \begin{document}$ H^4 $\end{document} -norm of the initial data. Using a compactness argument, we further obtain the existence of weak solutions which may have discontinuities across some hypersurfaces in \begin{document}$ \mathbb R^3 $\end{document} . We also provide a blow-up criterion of solutions in terms of the \begin{document}$ L^\infty $\end{document} -norm of density.
Electromagnetic Field Propagation and Indoor Exclusion Zone Analysis in a Nuclear Power Plant

This article investigates the electromagnetic field strengths and the resulting indoor exclusion zones (EZs), taking into account the actual indoor nuclear power plant (NPP) environment. To obtain the accurate indoor EZ, a real indoor environment based on the simulator room of Korea Institute of Nuclear Safety was included in the numerical simulation. The maximum distance d of the indoor EZs depending on the position and polarization of the emitter is 1 to 2.1 times longer than the distances d of the free-space EZs. To validate the simulated indoor EZs, electromagnetic field strengths along the arc line with an arbitrary distance from the emitter are measured in the NPP, which are in good agreement with the simulation results. The result demonstrates that the indoor EZ should be investigated before applying the wireless system in the NPP because the indoor EZ and free space EZ can be significantly different.
Knowledge Management in the Decommissioning of Nuclear Facilities in Brazil

In the second half of the twentieth century in Brazil, several nuclear facilities were built for the most varied objectives. The largest number of such facilities is at the Nuclear and Energy Research Institute in Sao Paulo (IPEN-CNEN/SP). For different reasons, some of these facilities had their projects finalized and were deactivated. Some of the equipment was then dismantled, but the respective nuclear and radioactive material remained isolated in the original sites awaiting the proper decommissioning procedures. The Celeste Project is an example of a facility where the nuclear material has been kept, and is subject to Argentine-Brazilian Agency for Accounting and Control of Nuclear Materials (ABACC) periodic inspections. Because of a number of interests, including financial and/or budgeting situations at the institutions, decades have passed without any further action, and the people who withold information and knowledge about these facilities have already moved away from the area or are in the process of. Therefore, because of the absence of knowledge management techniques in force at the time of establishing and operating these installations, this work proposes an analysis about the possible consequences in case of loss of perhaps the only one remaining knowledge, the one from the people who designed those departments and worked there.
Knowledge attitude and practices of childhood diarrhea and ORS administration in diarrhea amongst mothers of children below age 5 years: A hospital based cross-sectional survey

Introduction: Basic minimal information about care of children in diarrhea and ORS use is necessary for early recovery. To plan anti diarrheal program, its important to know the knowledge, beliefs, practices of diarrhea understanding and management including ORS; in community. Methods: A crosssectional survey of 300 serial mothers of under five children presenting to a hospital were enrolled and data regarding awareness of loose motion definition; ORS use, diet in diarrhea and beliefs and practices was collected by using a prevalidated questionnaire. Results: Most (74.59%} mothers were in age group of 20-30 year old home makers. Only 31.97% wereaware of diarrhea leading to dehydration. Teething was considered a prime cause of diarrhea by 32.64% mothers. Rice based food was preferred in diarrheas by only 45.96% mothers. Only 35.26% knew that extra fluids are needed in diarrheas. Sixty six percent mothers had knowledge of home based ORS but only 22% knew correctly. ORS dose was not known to 89.5% of mothers. Conclusion: There is a serious need for modifying diarrhea control programs with community education.Incomplete information is likely to cause complications and delay in recovery.
The ram effect will advance puberty in 9 to 10 month old Merinos ewes independent of their season of birth.

Season of birth, nutrition, live weight and social interactions have all been implicated as factors determining the time of puberty in the lamb (reviewed by Dyrmundsson 1981). Normally growing spring-born lambs usually exhibit their first oestrus during the first available breeding season (autumn and winter), but lambs born in autumn do not display their first oestrus until the following autumn. The roles of age and live weight as determinants of puberty are confounded by season of birth. Foster (1981) hypothesised that lambs mature physiologically at the same age and live weight independently of their season of birth but that in autumn-born lambs the unfavourable spring photoperiod causes lambs to pass directly from the prepubertal state to the seasonal anoestrous state. Both conditions, it is hypothesised, are controlled by negative feedback of oestradiol (Ez) on the secretion of luteinising hormone (LH).

How to Engage with Sustainability Issues We Rarely Experience? A Gamification Model for Collective Awareness Platforms in Water-Related Sustainability

Collective awareness platforms offer innovative ways to engage citizens in becoming aware of and contributing solutions to sustainability challenges, such as climate change, water scarcity, or extreme weather events. Although such platforms have been successful in engaging citizens to contribute and self-organize during or directly after emergency situations, it has proven rather hard to motivate citizens to participate in preparing their local communities to address sustainability challenges whose effects are likely to be felt in the future and which they have not experienced yet. In this paper, we discuss the development, implementation, and assessment of a gamification model for a collective awareness platform for water-related sustainability challenges. The model is designed to address the motivational drivers of different user types and uses visualization elements to support gamified interaction in a way that relates otherwise intangible, abstract issues to more immediate (short-term), tangible objectives. The model was empirically validated with 507 users through a series of online experiments. The results confirmed a positive motivational effect in a large majority of participants and the suitability of the model to address different user types and various water-related sustainability issues. The findings will inform the design of gamification models for collective awareness platforms in sustainability-related domains.
Self-esteem of people who practice sport in relation to their experiencing the flow state and their style of coping with stress

The purpose of this work was to ascertain the association of the level of athletes’ self-esteem with their stress management and experiencing the flow state. The study included 56 men and 18 women, aged 19 to 25, who practiced sport and lived in Gorzów Wielkopolski and its vicinity. The following tools were employed: the Rosenberg Self-Esteem Scale, N.S. Endler and J.D. Parker’s Coping Inventory for Stressful Situations (CISS), and S. Jackson and D. Eklund’s Flow State Scale – 2. For the analysis of variables descriptive statistics, correlation measures (Pearson’s r) and regression analysis were used. It was found that there is a positive correlation at the level of 0.05 between high self-esteem and the task-oriented style of coping with stressful situations, and a significant negative correlation at the level of 0.01 between self-esteem and the emotion-oriented style of stress management. The level of self-esteem also correlates with experiencing the flow state. Self-esteem is an important predictor of the method of coping with stressful situations and experiencing the flow state. People with higher self-esteem achieve the state of a kind of felicity, an autotelic experience. They are aware of their own abilities, have the feeling that they effortlessly control their situation and themselves, and can distance themselves from the surrounding environment. In a stressful situation, they focus on the problem.
Allergic Bronchopulmonary Aspergillosis: An Occult Disease Waiting To Be Explored -

: Allergic bronchopulmonary aspergillosis (ABPA) is a slowly progressive disease caused by hypersensitivity to Aspergillus fumigatus . This condition is most commonly seen in patients with asthma and cystic ﬁbrosis. ABPA mimics a wide range of diseases, thereby further accentuating the difficulties faced by medical practitioners in diagnosing this condition. Even today, this condition remains under diagnosed in many countries with reports of mean diagnostic latency of ten years between the occurrence of symptoms and the diagnosis. We present a case report and review of literature with the aim of highlighting the complicated nature of this enigmatic illness. [Bhatia M NJIRM 2015; 6(6):106-112]
