Obstructive Sleep Apnea Knowledge Among Dentists and Physicians

Study Objectives: Obstructive sleep apnea (OSA) is a largely undiagnosed and untreated sleep disorder with public health implications. This study investigated whether dentists were as knowledgeable about OSA as physicians. Methods: Two convenience samples of California dentists were surveyed online (N=107) and in-person (N=63) between January and April 2019 using the 18 knowledge items from the validated Obstructive Sleep Apnea Knowledge and Attitudes (OSAKA) Questionnaire. California dentists’ total score was then compared to a compilation of published physicians’ total OSA-knowledge scores from 12 studies (2003-2020) using Chi-square tests with Bonferroni adjusted p < 0.0023. OSA-knowledge gaps and competencies were also compared on individual item data provided for nine of the published physician studies. Results: Mean total correct OSA-knowledge scores were 73.6% for California dentists (N=170) and 63.9% across all physicians (N=2,559); scores were 84.5% for Canadian otolaryngology residents (N=66), 75.6% for U.S. physicians (N=305), and 62.3% for all other non-U.S. physicians (N=2,188). The all-physician group had more knowledge gaps than dentists. Conclusion: Dentists had noninferior knowledge of OSA compared with most physician groups. Findings suggest that dentists may serve to increase the number of healthcare providers able to identify and treat patients with OSA, mitigating this healthcare gap. Suboptimal sleep medicine and OSA training in medical and dental education remains a challenge, perpetuating the public health ramifications of underdiagnosed and undertreated OSA. Clinical Implications: Engaging more dentists to identify patients at risk for OSA at the point of care and treat or refer patients for treatment, as appropriate, helps meet this public health need.
Diseño de Arrays de Ranuras Compuestas Mediante Circuito Equivalente

Results of the methodology presented in [1] is shown in this document. By means of the equivalent circuit model [2][3] of the slot, a combination of Method of Moments (MoM) and Forward Matching Procedure (FMP) is used to design a sub-array of compound slots. According to this, the system can be seen as a matched electric circuit and/or as a Nelements radiating device. Comparison between commercial solvers and proposed method are shown in this document, revealing that the mutual coupling between elements is a tiltingangle-dependant parameter.
A planar end‐loaded dipole phased array with enhanced bandwidth and wide‐angle scan

A bandwidth‐enhanced wide‐angle scanning phased array based on planar end‐loaded dipole elements is designed and analyzed in this paper. Initially, the phased array is designed based on wideband wide‐beam dipole elements, which are placed in a hybrid artificial structure composed of surface waveguide (SWG) and high‐impedance surface (HIS). An additional resonance caused by surface‐wave propagation in the SWG is generated close to the dipole resonance. The dual‐resonance mechanism improves the impedance bandwidth. Then, in order to enhance the array active reflection performance, the HIS is adopted to reduce the coupling between array elements which is caused by the excited surface waves. Besides, the SWG‐HIS hybrid structure has a zero‐phased reflection in the phased array operation band, which contributes to the wide‐angle scan. The total dimension of the proposed eight‐element phased array is about 3.24 λ0 × 0.675 λ0 (λ0 is the free‐space wavelength at 4.5 GHz). The phased array shows a main‐beam scan up to ±60° with a realized gain higher than 8.8 dBi and a total efficiency higher than 84% in an active reflection band of 4.35 ~ 4.85 GHz.
Spectral Fuzzing: Evaluation & Feedback

This paper presents an instrumentation framework for assessing and improving fuzzing, a powerful technique to rapidly detect software vulnerabilities. We address the major current limitation of fuzzing techniques, namely the absence of evaluation metrics and the absence of automated quality assessment techniques for fuzzing approaches. We treat the fuzzing process as a signal and show how derived measures like power and entropy can give an insightful perspective on a fuzzing process. We demonstrate how this perspective can be used to compare the efficiency of several fuzzers, derive stopping conditions for a fuzzing process, or help to identify good candidates for input data. We show through the Linux implementation of our instrumentation framework how the approach was successfully used to assess two different fuzzers on real applications. Our instrumentation framework leverages a tainted data approach and uses data lifetime tracing with an underlying tainted data graph structure.
Field calibration of computer models for application to buried liquid discharges: a status report

A field experiment for calibrating computer models was conducted. Data from the experiment were compared directly to the output of a computer model. The model inputs were estimated from in situ information and computer forecasts of moisture movement were made. The forecasts were biased at some points in the system. The bias could be removed by using improved estimates of the parameters. The model correctly forecast that horizontal movement would dominate in situ wetting patterns. 18 references, 21 figures, 5 tables.
Integration and Analysis of Heterogeneous Biological Data

We live in the era of networks. The power of networks is the most fundamental driving force behind the machinery of life. Living bodies stay alive through complex inter-regulations of biochemical networks and information flows through these networks with such a great intensity and complexity that it exceeds anything that the human ingenuity has been able to spawn so far. Due to this overwhelming complexity we have begun to see a rapid rise in studies aimed at explaining the fundamental concepts and hidden properties of such complex systems. This thesis provides a strong foundation of using networks to understand complex biological phenomenon like protein functions, as well as more accurate method of modeling gene regulatory networks. In the first part we presented a methodology that uses existing biological data with gene ontology functional dependencies to infer functions of uncharacterized proteins. We combined different sources of structural and functional information along with gene ontology based term-specific relationships to predict precise functions of unannotated proteins. Such term-specific relationships, defined to clearly identify the functional contexts of each activity among the interacting proteins, which enables a dramatical improvement of the annotation accuracy with respect to previous approaches. The presented methodology may be easily extended to integrate more sources of biological information to further improve the function prediction confidence. In the second part of this thesis we discussed an extended BN model to account for post-transcriptional regulation in GRN simulation. Thanks to this extended model, we discussed the set of attractors of two biologically confirmed networks, focusing on the regulatory role of miR-7. Attractors have been compared with networks in which the miRNA was removed. The central role of the miRNA for increasing the network stability has been highlighted in both the networks, confirming the cooperative stabilizing role of miR-7. The enhanced BN model presented in this thesis is only a first step towards a more realistic analysis of the high-level functional and topological characteristics of GRNs. Resorting to the tool facilities, the dynamics of real networks can be analyzed. Thanks to the extended model that includes post-transcriptional regulations, not only the network simulation can be more reliable, but also it can offer new insights on the role of miRNAs from a functional perspective, and this improves the current state-of-the-art, which mostly focuses on high-level gene/gene or gene/protein interactions, neglecting post-transcriptional regulations. Due to its discrete nature, the BN model may still neglect some regulatory fine adjustments. However, the largest number of the computed attractors, now including miRNAs, still represents meaningful states of the network. The simple glimpse into the complexity of the network dynamics, that the toolkit is able to provide, could be used not only as a validation of in vitro experiments, but as a real System Biology tool able to rise new questions and drive new experiments.
Mobile robot navigation using evolving neural controller in unstructured environments

Abstract Autonomous mobile robot navigation using only local sensory data in an unstructured environment poses a challenge for mobile robots. Our approach aims to evolve a single neural controller that simultaneously learns obstacle avoidance and target seeking without an explicit behavior switching scheme unlike some other recent approaches. We train the robot in a static, unmapped environment comprising of multiple obstacles of different shapes and sizes. We study 4 different training schemes that emphasize the learning objectives differently. The trained controller is validated by simulations across a diverse range of environments different from the training environment. A comparative study of the robot behavior under different objective functions has been done. We discuss the performance measured on the basis of several metrics.
BOGGLE Your Brain: An Online Forum for Obstetrics and Gynaecology Graduate Medical Education in a Tertiary Maternity Hospital [Version 2]

The abstract has been rewritten in the format of a standard research article. A more tenuous link between face-to-face and online education needed to be made clear – this has been attempted with the addition of selected “BOGGLE” posts, as well as further description of educational methods in the obstetric department in question. These aspects address both post content and also further describe the concept of blended learning within the graduate medical educational programme. Abstract Introduction: Social media platforms are increasingly used in Medical Education to facilitate collaboration, interaction and discussion. In the area of graduate medical education (GME), platforms such as Twitter, podcasts, blogs, YouTube, Skype and wikis have been reported. Outcomes relating to knowledge acquisition, professionalism and the eﬀect of social media proﬁles on recruitment have been reported (Sterling et al. , 2017). Methods: In this paper we describe the use of Yammer (Microsoft) to host an online forum called "BOGGLE" for trainees in Obstetrics and Gynaecology, to facilitate the delivery of their educational program at a tertiary teaching hospital. BOGGLE activity and membership were retrospectively examined over a period of approximately 24 months, using the "group insights" Yammer function. Results: BOGGLE activity increased signiﬁcantly over the study period. Members included O&G Weekly BOGGLE usage activity trends indicated interaction was highest on weekdays. It was not possible to track trends in individual usage, or to assess volumes of particular "tags". Conclusions: BOGGLE provided a highly engaging platform for education that reached far beyond the original target audience of O&G trainees. Further analysis of post content and individual activity may provide more insight into the utility of Yammer as a platform for education in this context.
A Fuzzy Model for Combating Misinformation in Social Network Twitter

Constant and rapid increase of social media users implies the increase of spread of misinformation in social media networks. One of the leading networks Twitter is becoming significant source of information and news for online users. This research proposes a new approach to the problem of combating misinformation in social media network Twitter. The approach is based on the SI (Epidemic) Fuzzy Model to combat the spread of misinformation on Twitter. The mathematical model is given by a system of differential equations including fuzzy parameters and factors that describe various characteristics of misinformation spread in complex network. We also reflect on current challenges in combating misinformation in social media with the goal to stimulate future research in that domain by pointing out important factors that need to be taken into account while developing a model for combating misinformation.

Envelhecimento e tecnologia nos territórios do interior de Portugal

Ageing and technology in the territories of the interior of Portugal. The PerSoParAge project Personal and social resources for autonomy and social participation in an ageing society, aims to develop proposals and tools for analysis and intervention that respond to the challenges of the aged regions of the interior of Portugal, starting from an assessment of the territory, in Castelo Branco, Guarda and Portalegre districts. The consortium representing the project is formed by the Castelo Branco Polytechnic Institute, Portalegre Polytechnic Institute, Guarda Polytechnic Institute, Bragança Polytechnic Institute, Castelo Branco City Council and Idanhaa-Nova City Council. The project aims to know the processes and ageing profiles of the interior communities through multidimensional assessment with a view to defining their social, functional and available resources profile, as well as identifying the needs of these communities’ organizations. This paper presents data from the knowledge, use and potential evaluation component of Information and Communication Technologies by older people in the studied regions. The methodology used was predominantly quantitative, with resource to apply two surveys per questionnaire, one for individuals aged 50 to 64 years and the other for the population aged 65 and over. This instrument was specifically designed for this purpose, validated by experts, containing closed and open response questions. The analysis and discussion of the results will allow the construction of knowledge that responds to the challenges of demographic changes felt in the regions covered and the development of intervention strategies and territorial policies of ageing, namely solutions that promote the use of digital and assistive technologies, in order to improve the quality of life of older people and promote their integration, participation and involvement in the development of territories.

Rotating-disc biological treatment of acid mine drainage

The rotating biological contactor (RBC) was investigated for application to treatment of acid mine drainage, specifically, oxidation of Fe/sup 2 +/ to less soluble Fe/sup 3 +/. At three coal mining locations in Pennsylvania and West Virginia, treatment of six heterogeneous mine waters was studied in experiments with pilot-scale (0.5-m diameter) and prototype (2.0-m) RBC units. Specific characteristics examined in detail for their effect on biological treatment were temperature, pH, and influent Fe/sup 2 +/ concentration. Continuous biological oxidation of Fe/sup 2 +/ was accomplished at natural mine water temperatures as low as 0.4/sup 0/C (Hawk Run, Pa.) and as high at 29/sup 0/C (Crown, W.Va.). Performance of the RBC was unaffected at influent mine water pH valves in the range of 2.18 to 5.50 (Crown, W.Va.). Lower influent Fe/sup 2 +/ concentrations in Hollywood, Pa. mine drainage (71.6 mg/l) resulted in higher oxidation efficiency as compared to treatment efficiency when mine water contained approximately twice the influent Fe/sup 2 +/ content.
The linking of angiogenesis to contractile performance and substrate metabolism in the hypertrophied and failing heart

It has been suggested that a failure of angiogenesis (capillary growth) to keep pace with myocyte expansion is the driving force which pushes hypertrophied hearts into a state of failure marked by contractile dysfunction and alterations in the mechanisms governing energy production. The aims of this study were to investigate how alterations in ventricular capillarity affect contractile performance and substrate metabolism in the isolated rat heart. It was hypothesised that, if cardiac contractile performance and substrate utilisation are directly related to ventricular capillarity then methods to alter the number and distribution of capillaries within the ventricle could be utilised to demonstrate this relationship. Treatment regimes were split into those aimed at inducing new capillary growth (e.g. chronic bradycardia and exposure to cold environments) and those aimed at reducing ventricular capillarity (e.g. hypertension and beta-adrenoceptor stimulation). In contrast to previous reports, capillary growth within the ventricle was very limited in animals exposed to a chronic increase in energy demand (e.g. cold environments) and those subjected to extended periods of mechanical stimulation (e.g. bradycardia). Ventricular remodeling appears to accommodate for alterations in the load and/or energy demand without the need for an expansion of the existing capillary network. Experiments conducted in beta-adrenoceptor mediated hypertrophy demonstrate that capillary rarefaction has little effect on cardiac contractile performance and experiments with hypertensive animals show no capillary growth despite the dramatic increase in energy demand placed on the heart in these conditions. In conclusion these data demonstrate surprising plasticity in the response of the myocardium to a number of physiological and pathological stimuli and indicate that adequate compensation occurs without the need for expansion of the existing capillary bed. The limited angiongenic capacity of the myocardium may therefore indicate that the capillary supply of the ventricle is not limiting to the function of the heart.
Educational use cases from a shared exploration of e-books and iPads

E-books and e-book readers are becoming increasingly widely available, particularly for the general reader, and there have been many studies on their adoption. However, less is known about their use for educational and academic purposes. We report here on work carried out on e-books and e-book applications using iPads by academic and teaching staff. After considering pedagogical issues and reporting survey results, we identify a spiral of six key use case areas for e-books. This spiral of use cases moves from basic e-book use, through situational reading, e-books and learning, using multiple learning resources, collaborative/group learning, to e-book production. We discuss each of these use case areas and provide guidelines that will be of interest to practitioners and researchers alike.
MEASUREMENTS AND MODELING IN SPEECH PRODUCTION RESEARCH

Early measurements of the vocal tract have led to numerous insights into the way the acoustic signal is shaped by the mouth. One important adjunct to measurement has been analog modeling and detailed acoustic analysis. Some early measurements, such as Stevens’ exemplary x-ray film, are still being analyzed today, due to the continuing challenge of measuring the speech articulators. Although x-ray movies have provided the fullest depiction of the moving vocal tract, they are difficult to obtain and quantify. Recent point source measurements (electromagnetometry and x-ray microbeam) have been successful in characterizing anterior tongue movements, but their inherent limitations prevent imaging of the pharynx, which has a large effect on the acoustic output. Very recently, cine MRI and opticallycorrected ultrasound have surpassed the x-ray capability of obtaining large data sets of images of the vocal tract during running speech. These techniques are less demanding on the speaker and thus applicable to a wider range of talkers. With these new measurements, we should be able to refine our modeling, which always has compromises, and to better explore the relationship between vocal tract shape and the resulting acoustics. They should also help us address the inverse problem (i.e., that there are, theoretically, many possible tract shapes that can result in a given spectrum), and allow us to examine changes in articulator position that do not result in measurable acoustic differences. We are poised to build upon the substantial foundations of speech production research and advance to additional insights with these new techniques.
PACERS: Platoon Aid for Collective Employment of Robotic Systems

Abstract : This report presents guidance to help train platoons equipped with organic unmanned systems. The Army currently is supplying platoons with both prototype and commercially available unmanned systems to evaluate military utility and to develop tactics, techniques, and procedures; however, the training provided prior to these experiments focuses almost entirely on individual operator training. While different unmanned systems require different detailed procedures, there are certain aspects of operation applicable across systems, and training could be given on these system-general aspects of employment. The purpose of this report is to (1) lay out these system-general aspects and (2) suggest a list of activities to focus on to help train system integration. Each activity has associated observations and related after-action review questions applicable to both air and ground assets, and avoiding the particulars of any specific system. Trainers will not have the opportunity to become conversant with the specifics of the myriad of systems they may encounter. Besides being system general, the training guidance provided is also mission-general. It suggests appropriate observations and questions to facilitate coaching and after action review discussion specifically with respect to system employment. Therefore, these represent an addition to, not a replacement of, mission-specific observations and after-action review topics.
Kinetic Analysis of Lower Body Resistance Training Exercises

This study evaluated and compared the peak vertical ground reaction force (GRF) and rate of force development (RFD) for the eccentric and concentric phases of 4 lower body resistance training exercises, including the back squat, deadlift, step-up, and forward lunge. Sixteen women performed 2 repetitions of each of the 4 exercises at a 6 repetition maximum load. Kinetic data were acquired using a force platform. A repeated measures ANOVA was used to evaluate the differences in GRF between the exercises. Results revealed significant main effects for GRF both the eccentric (p ≤ 0.001) and concentric (p ≤ 0.001) phases. Significant main effects were also found for RFD for the eccentric (p ≤ 0.001) and concentric phases (p ≤ 0.001). Force and power requirements and osteogenic potential differ between these resistance training exercises.
