Quantitative performance evaluation of Bayesian neural networks

Due to the growing adoption of deep neural networks in many ﬁelds of science and engineering, modeling and estimating their uncertainties has become of primary importance. Various approaches have been investigated including Bayesian neural networks, ensembles, deterministic approximations, amongst others. Despite the growing litterature about uncertainty quantiﬁcation in deep learning, the quality of the uncertainty estimates remains an open question. In this work, we attempt to assess the performance of several algorithms on sampling and regression tasks by evaluating the quality of the conﬁdence regions and how well the generated samples are representative of the unknown target distribution. Towards this end, several sampling and regression tasks are considered, and the selected algorithms are compared in terms of coverage probabilities, kernelized Stein discrepancies, and maximum mean discrepancies.
Magnetic Field Effect on Multiplicity of Solutions Induced by Thermosolutal Convection in a Bénard Square Porous Cavity Submitted to Horizontal Concentration Gradient

In this work, we present a numerical study of the magnetic field effect on double diffusive natural convection in a square porous cavity saturated with an electrically conducting binary mixture. The cavity is heated from below and cooled from the top, while its vertical walls are adiabatic and maintained at constant but different concentrations. The numerical results are obtained for a Lewis number Le = 10 and the following ranges for the other controlling parameters: 40 ≤ RT ≤ 1000, -0.2 ≤ N ≤ 0.2 and -0.5 ≤ Ha ≤ 0.5, where RT, N and Ha are the thermal Rayleigh number, the buoyancy ratio and the Hartmann parameter, respectively. First, the effect of the Hartmann parameter on the maintenance and disappearance of the multiple steady state solutions obtained in the case of purely thermal convection is examined. Then, the combined effect of N and Ha on the existence of these steady solutions is analyzed. It is found that the critical values of N corresponding to the transitions between the different solutions are modified by the application of a magnetic field. However, the nature of the transitions is unchanged. It is shown that the magnetic field may affect considerably the flow intensity and the heat and mass transfer in the medium.
Measurement of CP violation in B 0 → J/ψK 0 S decays

: Measurements are presented of the CP violation observables S and C in the decays of B 0 and B 0 mesons to the J/ψK 0 S final state. The data sample corresponds to an integrated luminosity of 3 . 0 fb − 1 collected with the LHCb experiment in proton-proton collisions at center-of-mass energies of 7 and 8 TeV. The analysis of the time evolution of 41500 B 0 and B 0 decays yields S = 0 . 731 ± 0 . 035 (stat) ± 0 . 020 (syst) and C = − 0 . 038 ± 0 . 032 (stat) ± 0 . 005 (syst). In the Standard Model, S equals sin(2 β ) to a good level of precision. The values are consistent with the current world averages and with the Standard Model expectations.

Reduction of Sonication-Assisted Graphene Oxide via Chemical and Thermal Treatments

Graphene has sparked an intense interest in the energy field over the recent years due to its excellent mechanical, electrical, thermal and optical properties. There are several ways to produce graphene, however, large-scale production of this material is still an issue and subjected to intense research effort. In this work, graphene oxide (GO) was first synthesized using sonication-assisted oxidation of graphite followed by reduction process. The reduced graphene oxides (rGOs) are then produced using two routes; chemical L-ascorbic acid (AA) reduction and thermal reduction (T). The sonication process facilitates the washing step and reduces the time required to produce rGOs. The chemical and structural properties of the rGOs were comparatively investigated using XRD, FTIR, BET and FESEM. Results showed that both chemical and thermal methods were effective in removing oxygen-containing functional groups in GO and restore the electrical conductivity of the obtained rGO. rGO-T700 had the highest electrical conductivity (56.39 S/m) in comparison to rGO-T300 (15.87 S/m) and rGO-T500 (35.6 S/m) that were obtained using thermal reduction method. The rGO-AA, which used L-ascorbic acid as a reductant possessed an electrical conductivity of 46.87 S/m. Although this value was slightly lower as compared to rGO-T700, it still demonstrated the potential of using environmentally friendly ascorbic acid for rGO synthesis compared to thermal reduction. The elimination of high temperature reduction could significantly save the production cost and it is believed that further optimization of reduction process parameters might enhance the conductivity of rGO-AA.

NUTRITIONAL ENDOCRINOLOGY Coffee consumption and hip fracture risk: a meta-analysis

To investigate the effect of coffee consumption on hip fracture risk, a meta-analysis was conducted. The PubMed database was screened for all published studies about coffee consumption and hip fracture through to November 2011. Reviews, PubMed option ‘related articles’ and references of retrieved papers were also searched for potentially relevant papers. Only studies that contained OR with 95 % CI for the association between coffee consumption and hip fracture risk were included. The summary risk estimates were calculated by fixedand random-effects models. Subgroup analyses were carried out stratified by study designs and participant characteristics, respectively. A total of six prospective cohort studies and six case–control studies were included in the final analysis. The pooled OR displayed increased risk of hip fracture by 29·7 % (95 % CI 0·960, 1·751; P= 0·09) for the highest compared with the lowest coffee consumption by the random-effects model (P for heterogeneity = 0·000; I = 84·0 %), but the result had no statistical significance. Subgroup analyses showed that coffee consumption significantly increased hip fracture risk by 54·7 % (95 % CI 1·152, 2·077; P= 0·004) among women, by 40·1 % (95 % CI 1·015, 1·935; P= 0·040) for elderly participants aged over 70 years, and by 68·3 % for Northern Americans (95 % CI 1·492, 1·899; P= 0·000). Other subgroup analyses according to data published before the year 2000 showed a positive association between coffee and hip fracture risk, and followup duration also positively affected hip fracture risk, especially when the follow-up length was less than 13 years. Although our meta-analysis has provided insufficient evidence that coffee consumption significantly increases hip fracture risk, coffee intake may increase hip fracture risk among women, elderly participants and Northern Americans. No dose–response pattern was observed.
Transcriptome sequencing reveals altered ciliogenesis under hypoxia in nasal epithelial cells from chronic rhinosinusitis with nasal polyps

Abstract Background Hypoxia is considered a key factor in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP). However, the specific mechanism driving polypogenesis under hypoxic conditions is unclear. This study aimed to explore hypoxia‐induced alterations in the transcriptome of human nasal epithelial cells (HNECs) in vitro. Methods HNECs derived from the tissue of patients with CRSwNP were established as air–liquid interface (ALI) cultures. Confluent cultures were kept submerged or treated with cobalt chloride (CoCl2) to induce hypoxia. Transcriptome analysis was used to identify key mRNAs involved in this process. Real‐time PCR (RT–PCR), Western blotting, and immunofluorescence were used to observe the effects of hypoxia on ciliogenesis. Results Numerous genes, biological processes and pathways were altered under submerged culture conditions or after CoCl2 treatment. Analysis of the results under both hypoxic conditions revealed that the transcriptional program responsible for ciliogenesis was significantly impaired. Downregulation of cilia‐related genes and inhibition of ciliated cell differentiation under hypoxia were confirmed by RT–PCR, Western blot and immunofluorescence analyses. Conclusion Hypoxia impairs ciliogenesis and ciliary function in HNECs, which might play a role in the pathogenesis of CRSwNP.
Regulation of Myocardial bARK1 Expression in Catecholamine-Induced Cardiac Hypertrophy in Transgenic Mice Overexpressing a1B-Adrenergic Receptors

OBJECTIVES Using a transgenic mouse model of myocardial-targeted overexpression of the wild-type a1B adrenergic receptor (AR) (Tga43), we studied the role of the bAR kinase (bARK1) in the evolution of myocardial hypertrophy and its transition to heart failure (HF). BACKGROUND Increased myocardial expression of bARK1 has been shown to be associated with HF and certain models of hypertrophy. METHODS Tga43 mice and their nontransgenic littermate controls were treated with the a1AR agonist phenylephrine (PE) for 3, 7 or 14 days to characterize the cardiac consequences. RESULTS Nontransgenic littermate control mice treated for 14 days with PE display cardiac hypertrophy with no increase in bARK1 expression. However, Tga43 animals show a reduced tolerance to 14-day PE treatment, demonstrated by reduced survival and severe cardiac hypertrophy. Moreover, PE treatment for three and seven days in Tga43 mice resulted in an exaggerated hypertrophic response accompanied by significant cardiac biochemical abnormalities that are normally associated with HF, including fetal gene expression, reduced bAR density and enhanced bARK1 expression. We also found reduced myocardial stores of the sympathetic neurotransmitter neuropeptide Y. CONCLUSIONS These data suggest that PE-treated Tga43 mice have chronic activation of the cardiac sympathetic nervous system, which may be responsible for the appearance of apparent maladaptive hypertrophy with an evolution towards HF and sudden death. Thus, the cardiac phenotypes found in these mice are not the direct result of enhanced a1BAR signaling and suggest that bARK1 is a key molecule in the transition of myocardial hypertrophy to HF.

Design of observers for Takagi-Sugeno descriptor systems with unknown inputs and application to fault diagnosis

This paper presents a method for state-estimation of Takagi -Su eno descriptor systems (TSDS) affected by unknown inputs (UI). For ease of implementation’s sake, the proposed observers are not in descriptor form but in usual form. Sufficient existence conditions of the unknow input observers are given and strict linear matrix inequalities (LMI) are solved to determine the gain of the ob servers. If the perfect unknown input decoupling is not possible, the UI observer is designed in order to minimise th e L2-gain from the UI to the state estimation error. The two previous objectives can be mixed in order to decouple the estimation to a subset of the UI, while attenuating the L2 gain from the other UI to the estimation. The proposed UI obse rvers are used for robust fault diagnosis. Fault diagnosis for TSDS is performed by designing a bank of observ ers. A simple decision logic and thresholds setting allow to determine the occurring fault. The results are esta blished for both the continuous and the discrete time cases. The proposed method is illustrated by a numerical example.
Parental COPD as a Risk Factor for the Development of COPD and Disease Severity in Offspring: A Systematic Scoping Review

Background There is sparse literature on parental chronic obstructive pulmonary disease (COPD) as a risk factor for the development of COPD in adult offspring, and the impact on disease severity. We aimed to map the literature reporting on the prevalence of and/or association between parental COPD and COPD in offspring, and to evaluate whether or not the literature reports on the severity of COPD or other health-related outcomes in offspring with parental COPD. Methods A systematic literature search in Embase and Ovid MEDLINE was performed in June 2021. Search terms revolved around COPD and predisposition. Results Thirteen studies were identified: 10 case–control studies, two cross-sectional studies and one cohort study. Population size varied from 44 to 2668 offspring cases; the distribution of female cases varied from 5% to 80% and mean age ranged from 27 to 65. Nine studies used an antecedents approach and evaluated the prevalence of parental COPD in patients with COPD, which ranged from 19% to 58%. Four studies used a descendants approach, by identifying patients with COPD and subsequently evaluated prevalence of COPD in their offspring, and found a prevalence of 0% to 17%. Apart from one, all the studies found an increased odds ratio for COPD in individuals with parental COPD. Four studies reported on parental smoking history and nine studies reported on smoking history in offspring. Three studies evaluated the association between parental COPD and COPD-related outcomes in patients with COPD. Conclusion This review indicates that parental COPD is associated with a higher risk of COPD in offspring. The literature is sparse, and we identified a knowledge gap on whether parental COPD is a risk factor for severe COPD and other health conditions in offspring.
Overrun Handling for Mixed-Criticality Support in RTEMS

—Real-time operating systems are not only used in embedded real-time systems but also useful for the simulation and validation of those systems. During the evaluation of our paper about Systems with Dynamic Real-Time Guarantees that appears in RTSS 2016 we discovered certain unexpected system behavior in the open-source real-time operating system RTEMS. In the current implementation of RTEMS (version 4.11), overruns of an implicit-deadline task, i.e., deadline misses, result in unexpected system behavior as they may lead to a shift of the release pattern of the task. This also has the consequence that some task instances are not released as they should be. In this paper we explain the reason why such problems occur in RTEMS and our solutions.
Comparative Analysis of Chemical Composition andAntibacterial and Anti-Inflammatory Activities of theEssential Oils from Chrysanthemum morifolium ofDifferent Flowering Stages and Different Parts

The inflorescence of Chrysanthemum morifolium Ramat. , a well-known traditional Chinese herb, has been proved to have a certain inhibitory effect on some bacteria; however, its main components and acne bacteria inhibition effect remain to be elucidated. In this study, GC-MS was used to analyze the components of different flowering stages and different parts and to study the inhibitory effects of six essential oils on S. aureus and P. acnes and their alleviating effects on THP-1 cell inflammation. GC-MS combined with relative retention index method analyzed results stated that the 5 samples of C. morifolium to detect the 124 kinds of volatile components, including (E)-tibetin spiroether, are first detected in the volatile oil of the C. morifolium, and the content of (E)-tibetin spiroether is higher in immature inflorescence of C. morifolium and decreases as it extends its flowering period. Furthermore, the research results of inhibiting common acne-causing bacteria showed that the bacteriostatic effect of essential oils from JH at different flowering stages was better than that from JM and TJ, while the bacteriostatic effect of essential oil from stem and leaf of C. morifolium (SLC) at different parts was better than the roots of C. morifolium (RC). Finally, it was proved that the essential oil from SLC and C. morifolium could alleviate the inflammation of THP-1 cells induced by P. acnes. In conclusion, the antibacterial and anti-inflammatory effects of C. morifolium essential oil may be related to heterospiroolefins compounds, and the antibacterial activity decreases with the prolongation of flowering stage. It was suggested that volatile oil from C. morifolium and SLC could be used as effective components of antibacterial and anti-inflammatory cosmetics.
Oral Hygiene Practices and Awareness of Pregnant Women about the Effects of Periodontal Disease on Pregnancy Outcomes

Objectives Adverse pregnancy outcomes, such as preterm low birth weight (PTLBW), is a severe public health issue that needs to be dealt with by educating the general female population, dental practitioners, and gynecologist. One of the major contributing factors is periodontal disease, which accounts for about 18.2% of all PTLBW cases worldwide, and prevention of the same could reduce the occurrence of PTLBW babies. This study aimed to assess the oral hygiene practices and awareness of pregnant women about the effect of periodontal disease on pregnancy outcomes. Methods A descriptive cross-sectional study was conducted where 400 pregnant women after consent were requested to complete an anonymous, self-administered, structured questionnaire with twenty-one close-ended questions. Results Only 5% of participants in this study reported that gum diseases during pregnancy lead to preterm labor or low birth weight babies. About 70.7% of pregnant women mentioned that they did not use any interdental cleaning aids, and 54.5% did not use mouthwashes. Conclusion Tooth brushing practices among pregnant women were good; however, there was an overall lack in the use of adjunctive aids. The study highlighted a deficiency in the awareness of pregnant women regarding the association between periodontal disease and adverse pregnancy outcomes.
Practicing patients’ rights in Iran: a review of evidence

Protection of patients' rights is critical in improving healthcare quality, and hence this study aimed at reviewing patient rights’ practices in healthcare organizations of Iran. Using systematic search, this review was conducted based on Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). Several keywords, including "patient rights", "patient bills of rights" and "patients rights’ charter" were searched bilingually in the databases of SID, Magiran, PubMed, Scopus, and Web of Science from 2010 to 2021, and then, following a three-tier screening using the Critical Appraisal Skills Program (CASP) checklists, 76 articles were extracted. The degree of compliance with the Patients' Rights Charter (PRC) in healthcare organizations was 60.88% on average. As to the observance of the PRC dimensions, respectively, the highest and lowest scores were related to the "right to privacy and confidentiality" (70.16%) and "right to access an efficient complaining system" (53.01 %). Respect for patients' rights in organizations was assessed at a moderate level, and some aspects of patients' rights should be attended to immediately. Therefore, discrepancies in the dimensions of patients' rights and their implementation by organizations should be on the agenda of healthcare managers and policymakers.
Effectiveness of Mobile Application for Promotion of Physical Activity Among Newly Diagnosed Patients of Type II Diabetes – A Randomized Controlled Trial

Background: Mobile health intervention shows the positive effects on the management of chronic diseases. Therefore, the study was planned to study the effectiveness of a mobile-based application promotion of physical activity among newly diagnosed patients with type II diabetes. Methods: The present study was a parallel-design randomized controlled trial conducted over 2 years. The participants were type II diabetes patients between 18 and 60 years within 3 months of diagnosis who attended the endocrinology outpatient department having knowledge of using smart phone. The sample size was calculated to be 66 and 33 for each arm. The block random design method was adopted for allocation into different arms. A pretested interview schedule was used for the collection of data. Outcomes included body mass index, waist circumference, body fat percentage, and changes in the physical activity was obtained by global physical activity questionnaire (GPAQ). The information thus collected were processed and analyzed using SPSS v 20. Results: The study included 66 patients aged between 18 and 60 years, out of which 33 were enrolled into control and 33 into intervention group. The mean age of the participants was 42.29 ± 9.5 years ranged from 25 years to 59 years, 65.2% were males and 34.8% were females. It was observed that a higher proportion of intervention participants met WHO recommendations of physical activity level. Total metabolic equivalent of task (MET) value per minute (Mean ± SD) was 1347.27 ± 1028.5 in the control group and 1223.03 ± 584.87 in intervention group at baseline and was not different (P = 0.538). The total MET value per minute was found to be higher among the intervention group in all follow-ups. There was a significant decrease in weight, BMI, waist circumference, hip circumference, body fat percentage, and systolic blood pressure (SBP) in the intervention group. Conclusions: Cost-effective, simple mobile applications may help in routine clinical practice to encourage the patients for the promotion of physical activity.
