Data processing method in a context-aware system to provide intelligent robot services based on big-data

In order to recognize the situation and to provide robot services based on big data, it is necessary to implement a machine learning model capable of analyzing big data and a method for providing this data to the analysis model for learning. Previous researches have focused on the implementation of various data analysis models to analyze the collected big data. However, in these researches, it is difficult to recognize the new data which is not learned by the analysis model, and further research is needed to solve it. In this paper, we propose a data processing method to provide context-aware information in context-aware system based on big data to provide intelligent robot services. The proposed data processing method can convert the data generated in the domain in which the robot is running to learn data of the machine learning model and provide it, thereby continuously improving the accuracy of the machine learning model. In the experiment, the context-aware information is provided through the prototype of the context-aware system with the proposed method.
Level of evidence in endodontics: what does it mean?

This review is a short summary of how the level of evidence in endodontics and endodontic research in particular is defined. The goal of this review is to help dentists and endodontists to become familiar with the evidence pyramid and thereby better evaluate the reliability of evidence on daily practices and choices in patient care. All medical treatment, including endodontic treatment, should be based on the best available evidence. In this review, the definition of evidence is presented and the different levels in the evidence pyramid are discussed with a special focus on endodontics. Much of the presently published endodontic research is done in vitro, which is regarded as the lowest level of evidence. However, it is important to understand that a low level of evidence does not mean that the research in itself is of poor quality or somehow unreliable. Instead, it means that one cannot draw conclusions from in vitro studies to clinical events with a high probability of accuracy. The in vitro results may be true, and often are, but more evidence from different types of studies such as case-control and cohort studies and even randomized controlled trials is needed to increase the probability that the results obtained in research do in fact correctly reflect the real events, e.g. level of probability of healing after a specific type of treatment for a specific disease. This review also discusses why the highest level of evidence may be difficult to obtain for a variety of practical and ethical reasons, and why not all endodontic treatment needs to be based on information from randomized controlled trials and systematic reviews.
Effects of ustekinumab on spondylitis-associated endpoints in TNFi-naïve active psoriatic arthritis patients with physician-reported spondylitis: pooled results from two phase 3, randomised, controlled trials

Background The interleukin-12/23p40-subunit-inhibitor ustekinumab significantly improved spondylitis-related symptoms through Week 24 in psoriatic arthritis (PsA) patients with peripheral arthritis and physician-reported spondylitis (PA-PRS) in PSUMMIT-1&2. We further evaluated ustekinumab’s effect on spondylitis-related endpoints in PSUMMIT-1&2 tumour necrosis factor-inhibitor (TNFi)-naïve patients with PA-PRS. Methods Patients with active PsA (≥5 swollen and ≥5 tender joints, C-reactive-protein ≥ 3.0 mg/L) despite conventional (PSUMMIT-1&2) and/or prior TNFi (PSUMMIT-2) therapy received subcutaneous ustekinumab 45 mg, 90 mg or placebo (Week 0, Week 4, Week 16). Changes in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) neck/back/hip pain question (#2) and modified BASDAI (mBASDAI, excluding PA) scores and Ankylosing Spondylitis Disease Activity Score (ASDAS) responses were assessed at Weeks 12 and 24. Results The pooled PSUMMIT-1&2, TNFi-naïve (n=747), PA-PRS (n=223) subset (158 with human-leucocyte-antigen (HLA)-B27 results) presented with moderate-to-severe spondylitis-related symptoms (mean BASDAI-neck/back/hip pain-6.51, mBASDAI-6.54, BASDAI-6.51, ASDAS-3.81). Mean Week 24 changes were larger among ustekinumab than placebo-treated patients for both neck/back/hip pain (−1.99 vs −0.18) and mBASDAI (−2.09 vs −0.59). Improvements in neck/back/hip pain and fatigue appeared numerically greater in HLA-B27+ than HLA-B27– patients; those for other domains were generally consistent. Greater proportions of ustekinumab versus placebo-treated patients achieved ASDAS clinically important improvement at Week 24 (decrease ≥ 1.1; 49.6% vs 12.7%; nominal p<0.05). Conclusions Improvements in BASDAI neck/back/hip pain and mBASDAI among ustekinumab-treated, TNFi-naïve, PsA patients with PA-PRS were clinically meaningful and consistent across assessment tools. Numerically greater improvements in neck/back/hip pain in HLA-B27+ than HLA-B27– patients, noted in the context of similar overall mBASDAI improvements between the subgroups, suggest ustekinumab may improve disease activity in TNFi-naïve PsA patients likely to exhibit axial disease.

Computed Tomography-guided Transthoracic Core Needle Biopsy of Lung Masses: Technique, Complications and Diagnostic Yield Rate

Objectives: Computed tomography-guided core needle biopsy has an important role in the accurate histopathological diagnosis of lung masses. The present study aims to share our results of computed tomography-guided percutaneous core needle biopsy of lung masses. Methods: A total of 117 patients had computed tomography-guided percutaneous core needle biopsy for lung masses between January 2017-September 2019 in our institution. In this study, these patients’ post-procedural complications, diagnostic-yield-rates and radiological-histopathological correlations were evaluated retrospectively. Results: Complications occurred in 23 (20%) patients (20 (17%) of pneumothorax; 3 (3%) of hemorrhage). Chest-tube-drainage was needed in five (4%) of all patients. No significant difference was found between complication rates and patient gender/age, tumor volume/localization or needle-path-length (p>0.05). In 77 of the 85 (91%) primary-lung-cancer-cases radiological and pathological diagnostic results were correlated. Conclusion: Computed tomography-guided core needle biopsy has a high diagnostic yield rate with acceptable complication rates in the diagnosis of lung masses.

Sources of funding in clinical trials: critical analysis

Clinical trials in the medical field are of great value for the discovery and confirmation of therapies against different diseases. However, one senses a possible bias in scientific articles published from clinical trials sponsored by industry. The CONSORT statement aims to avoid met hodological errors and interpretation of results in clinical trials. Thus, this article makes a critical analysis of item 25 of the 2010 update of the CONSORT statement on Sources of Funding in randomized clinical trials. Thus, there is a need for adequacy of clinical research, espe cially regarding the registration and ethics in finance in order to promote a real improvement of this research, fostering the emergence of new therapies.

Psychiatric issues in neurology Part I: Stroke

Psychiatrists and other clinicians working in general medical or specialized neurologic settings frequently encounter important psychiatric issues affecting diagnosis and management of patients with neurologic illnesses. These include cognitive impairment either as a primary presentation or as a secondary complication of a known neurologic condition such as multiple sclerosis; other psychiatric symptoms as a manifestation or complication of neurologic disease; and physical neurologic symptoms that do not correspond to any recognized pattern of neurologic disease, ie, conversion disorder or somatization disorder. In addition, behavioral, cognitive, or emotional symptoms may occur as a complication of drug therapy of neurologic disease. A more detailed coverage of these topics can be found elsewhere. 1,2 This column illustrates the principles of evaluating and treating psychopathology in neurologic illness in the most common disorder affecting the central nervous system, stroke.
Changing perceptions of tree resistance research

relating to its resistance to the fun-gus causing ash dieback, concluding that a breeding program may be a viable solution to this pest also. This issue provides a small snapshot of current tree resistance research. It shows encouraging trends and innovations, but is nota-bly lacking in primary papers reporting and applying genomic data. Well-designed genomic studies are urgently needed to turn the tide in tree resistance research. Once we have good case studies of rapid progress in breeding programs informed by genomic data, public perception of this field will change for good.
Retaining Talent In Smes Malaysia

More than 1 Million of employees in SMEs had migrated to other country since 1957. Approximately 38 percent of SMEs worldwide faced problem in finding a suitable talent worker for job position. In order to resolve serious brain drain issues in SMEs, this study is one of the pioneer study in Malaysia that examines the influence of pays, job satisfaction, working conditions, employment benefits, promotional opportunity and intrinsic rewards towards talent retention in SMEs. The researchers spent 3 months from 1 January 201931 March 2019 to collect 200 survey questionnaire, which were distributed to 200 employees aged 18-55 years old in 20 randomly selected SMEs in central region in Malaysia. Multiple linear regression was conducted to identify the significance of each independent variables towards independent variables. Pays (β = 0.211, p-value = 0.003) and promotional opportunity (β = 0350, p-value = 0.003) has significant positive relationship with talent retention. When pays and promotional opportunity increase, talent retention in SMEs will be intensified.
Robust control of brake systems with decoupled architecture

Modern brake systems have the tendency to decoupled brake system design involving electric and/or electrohydraulic brake actuators. In this thesis, a corresponding brake control architecture applicable for electric and automated vehicles is proposed and includes (i) base braking, (ii) brake blending and (iii) wheel slip control functions. Main focus has been given to the robustness of continuous wheel slip control during emergency braking in high and low road friction conditions. As the solution, several control laws were designed and experimentally validated during road tests. Results obtained for three vehicle prototypes with individual on-board and in-wheel electric motors and electrohydraulic brake-by-wire system present significant improvement in braking performance and ride quality compared to the conventional wheel slip control strategies.
Self-assessment vs. external evaluation of proficiency in English as a foreign language among student teachers

espanolUno de los objetivos de la Educacion Superior es la promocion del aprendizaje a lo largo de la vida y la autoevaluacion puede considerarse como uno de sus pilares fundamentales. Sin embargo, existen serias dudas sobre su fiabilidad y validez como herramienta de evaluacion. El objetivo de este estudio correlacional es explorar la precision de la autoevaluacion contrastada con las pruebas objetivas comparando los resultados de las correlaciones entre las pruebas de autoevaluacion realizadas por 46 estudiantes universitarios de ingles como lengua extranjera y su evaluacion externa, corregida por el profesorado, a fin de comprobar la precision de la autoevaluacion. Como instrumento de autoevaluacion se utilizaron los impresos de la Biografia del PEL y para la evaluacion externa un modelo tipo de las pruebas del FCE administradas por UCLES. Los resultados globales mostraron altos coeficientes de correlacion, demostrando que los estudiantes fueron precisos en la autoevaluacion de su dominio de la lengua inglesa, siendo estos mayores en las destrezas orales pero mas bajos en las escritas. Los resultados tambien revelaron correlaciones mas altas en las destrezas de expresion que en las de comprension. Este estudio contribuye a confirmar la precision y validez de la autoevaluacion como instrumento de evaluacion. EnglishOne of the aims of Higher Education is the promotion of Lifelong Learning and Self-Assessment (SA) could be considered as one of its main pillars. However, there are serious doubts about its reliability and validity as an evaluation tool. The aim of this correlational study is to explore SA accuracy contrasted to objective tests by comparing the results of the correlations between the SA tests conducted by 46 university (L2) English learners and their external evaluation, marked by teaching staff, for the purpose of testing the accuracy of SA. The SA tool used in the study was the Biography element of the European Language Portfolio (Form 3 of the ELP Passport for Adults); and that of the external evaluation was a model based on the Cambridge FCE tests administered by the UCLES. The results revealed that correlation on the overall scores were high, demonstrating that the students’ own assessments of their proficiency in the English language were accurate, being higher in the oral skills but lower in the written skills. The findings also revealed higher correlations in the expression skills than in the comprehension skills. This study contributes to affirm the accuracy and validity of SA as an evaluation instrument.
Who are the Champions? Inequality, Institutions and the Olympics

Does a country's level of inequality affect its ability to win Olympic medals? If it does, is it conditional on institutional factors? We argue that the ability of economically free societies to win medals will not be affected by inequality. In these societies, institutions generate incentives to invest in the talent pool of individuals at the bottom of the income distribution (people who are otherwise constrained in the ability to expend resources on athletic training). These effects cancel out those of inequality. In unfree societies, the incentives that promote investments in skills across the income distribution are weaker. Consequently, the effects of inequality on the ability to win are stronger. Using the Olympics of 2012 and 2016 in combination with the Economic Freedom of the World Index, we find that inequality only matters in determining medal numbers for unfree countries. We link these results to the debates on inequality.
All‐Fiber Structured Electronic Skin with High Elasticity and Breathability

With the rapid advancement in artificial intelligence, wearable electronic skins have attracted substantial attention. However, the fabrication of such devices with high elasticity and breathability is still a challenge and highly desired. Here, a route to develop an all‐fiber structured electronic skin with a scalable electrospinning fabrication technique is reported. The fabricated electronic skin is demonstrated to exhibit high pressure sensing with a sensitivity of 0.18 V kPa−1 in the detection range of 0–175 kPa. This wearable device could maintain prominent sensing performance and mechanical stability in the presence of large deformation, even when the elastic deformation is up to 50%. The electronic skin is easily conformable on different desired objects for real‐time spatial mapping and long‐term tactile sensing. Besides, it possesses high gas permeability with a water vapor transmittance rate of 10.26 kg m−2 d−1. More importantly, the electronic skin is capable of working in a self‐powered manner and even serves as a reliable power source to effectively drive small electronics. Possessing several compelling features, such as high sensitivity, high elasticity, high breathability as well as being self‐powered and scalable in fabrication, the presented device paves a pathway for smart electronic skins.
Spatial Models with Specific Error Structures

The purpose of this dissertation is to study the first order autoregressive model in the spatial context with specific error structures. We begin by supposing that the error structure has a long memory in both the i and the j components. Whenever the model parameters alpha and beta equal one, the limiting distribution of the sequence of normalized Fourier coefficients of the spatial process is shown to be a function of a two parameter fractional Brownian sheet. This result is used to find the limiting distribution of the periodogram ordinate of the spatial process under the null hypothesis that alpha equals one and beta equals one. We then give the limiting distribution of the normalized Fourier coefficients of the spatial process for both a moving average and autoregressive error structure. Two cases of autoregressive errors are considered. The first error model is autoregressive in one component and the second is autoregressive in both components. We show that the normalizing factor needed to ensure convergence in distribution of the sequence of Fourier coefficients is different in the moving average case, and the two autoregressive cases. In other words, the normalizing factor differs in each of these three cases. Finally, a specific case of the functional central limit theorem in the spatial setting is stated and proved. The assumptions made here are placed on the autocovariance functions. We then discuss some specific examples and provide a test statistics based on the periodogram ordinate.

Molecular Detection of the Predatory Bacterium Bdellovibrio bacteriovorus from Dental Biofilms

Introduction: The oral microbiome is a complex community whose composition results from multiple interactions among different microorganisms and with the host. Predatory prokaryotes are recognized as important balancing factors in different ecosystems. Among them Bdellovibrio bacteriovorus received special attention for its strong predatory behaviour against many human pathogens in the absence of any toxic or pathogenic effect, so that it was proposed as a live probiotic/antibiotic agent. This work aimed to evaluate if B. bacteriovorus is detected from samples of human oral and dental biofilm. Materials and Methods: Samples of oral and dental biofilm were obtained from 20 adults of both sexes and processed for extraction of metagenomic DNA, to be used as templates for B. bacteriovorus-specific PCR reactions. Specificity of amplification products was confirmed by sequencing. Results: All 20 dental biofilm samples and 12 of 20 (60%) oral biofilm samples were resulted PCR positive. The sequences of 17 of 32 PCR products (53.1%) showed 100% identity with the reference sequence; the sequences of 11 of 32 PCR products (34.4%) showed ≥99% identity, while the remaining 4 products (12.5%) showed identities ranging between
