Real-Time Processing and Quality Improvement of Synchrophasor Data

This paper proposes a real-time algorithm for processing and quality improvement of synchrophasor data (SD). The proposed algorithm first recovers the missing SD reported by phasor measurement units (PMUs), and performs low-rank approximation on data streams. Then, the enhanced data stream can be redirected toward various power system applications. The nonconvex matrix completion (MC) method with Schatten-q quasi-norm ( $l_{q}$ ) penalty is used to recover the missing SD in real-time. Unlike most MC methods which have been developed for batch data processing, the proposed method is able to perform fast recovery of streaming data even for high reporting rates of PMU data. The low-rank approximation method is used to suppress the noise of the streaming SD, and to efficiently compress the batch data for archiving. Real-life PMU data as well as simulation data are used to evaluate the performance of the proposed algorithms. The results obtained using both real experimental and simulation SD confirm that the proposed SD processing framework significantly improves the quality of data, particularly during transient conditions and in noisy environments.

It focuses on the advances of the discipline, particularly on the progress made in pre-agrarian plant use and the origins of agriculture. The main Palaeolithic and Epipalaeolithic sites where plant use has been well attested are discussed while issues such as pre-domestic cultivation and plant domestication are also analyzed.
Simultaneous Equations Model with Non-Linear and Linear Dependent Variables on Panel Data

This paper provides an estimation approach for the multi-equations’ systems in panel data. Multi-equations systems are at the heart of economic modeling. Researchers who want to establish causal links between two outcomes, often need to consider simultaneity between the latter, to overcome endogeneity issues (for instance when considering supply and demand equations). Difficulties arise when considering linear and non-linear outcomes at the same time and this is why Roodman [1] implemented the Stata module cmp for multidimensional models. In this paper, we further develop this technique to allow researchers to implement a simultaneous equations model in a panel dimension setting. Implemented under Stata, our method, xtcmp, is a Full Information Maximum Likelihood (FIML) estimator. This paper explains the associated theory (derivation of the log-likelihood function, the associated gradient and the Hessian matrices of the log-integrand function) and offers an application of t xtcmp, while making comparisons with cmp.
HEALTH INEQUALITIES: WHO IS THE MOST DISADVANTAGED AMONG THE UKRAINIAN WORKING-AGE POPULATION?

Despite inequalities in health, it is a very well developed topic, andtackling health inequalities is one of the main challenges of modern publichealth policies, these are not much explored in Ukraine.The European Social Survey data pooled together from 2004, 2006,2008, 2010, and 2012 including 6,820 Ukrainian respondents of working-age.Self-reported health was used as a dependent variable and four groups ofsocial determinants of health – as predictors. The multilevel binomial logisticregression analysis was conducted to investigate gender and social differencesin subjective health. Both genders were analyzed together and separately.Almost 60 % of the Ukrainian working-age population reported poor health.Multilevel binomial logistic regression analysis showed that respondents whowere female, married or had been divorced, and had children at home tendedto report poor health; the probability of poor health is increasing with age anddecreasing with the level of SES for both genders.Existence of between and within gender groups’ social inequalities inself-reported health as well as the most disadvantaged female subgroups arerevealed among the Ukrainian working-age population.
Esophageal Adenocarcinoma: Impact of a Large Hiatal Hernia on Outcomes After Surgery

Objective: To evaluate complete tumor resection rate (primary objective), 30-day postoperative outcomes, and survival (secondary objectives) in patients with a hiatal hernia (HH) ≥5 cm (HH group) compared with those who did not have a HH or presented with a HH <5 cm (control group). Background: HH is a risk factor for esophageal and junctional adenocarcinoma (EGJA). Its impact on the outcomes after EGJA surgery is unknown. Methods: Among 367 patients who underwent surgery for EGJA, a HH was searched for on computerized tomography scan and barium swallow, with comparison between the HH (n = 42) and control (n = 325) groups. Results: In the HH group, EGJAs exhibited higher rates of incomplete resection (50.0% vs 4.0%; P < 0.001), of pN3 stages (28.5% vs 10.1%; P = 0.002), and lower median survival (20.9 vs 41.0 mos; P = 0.001). After adjustment, a HH ≥5 cm was a predictor of incomplete resection (odds ratio 21.0, 95% confidence interval 9.4–46.8, P < 0.001) and a poor prognostic factor (hazard ratio 1.6, 95% confidence interval 1.1–2.5, P = 0.025). In the HH group, 30-day mortality was significantly higher in patients who received neoadjuvant radiotherapy (20.0% vs 0%; P = 0.040), which was related to greater cardiac and pulmonary toxicity. Conclusions: For the first time, we showed that a HH ≥5 cm is associated with a poor prognosis in patients who had surgery for EGJA, linked to greater incomplete resection and lymph node involvement. Neoadjuvant radiotherapy was associated with a significant toxicity in patients with a HH ≥5 cm.
Social Engineering Techniques, Password Selection, and Health Care Legislation: A Health Care Setting

Healthcare employees generally have access to view hospital patient’s medical records. This access can be simply viewing their chart or reviewing information on a computer screen. With this type of accessibly, hospital employees have the opportunity to view diagnosis, personal medical histories, as well as demographic information such as age and gender. Social engineers can use methods such as familiarity with co-workers for instance to obtain this information from unsuspecting health care workers. In addition, weak password selection can provide opportunities for a wealth of information to be stolen. In this chapter, current security legislation that addresses the security of patient’s health care records, social engineering tactics, and passwords are explored.
Additional Effects of Shank Adaptations in Children with Bilateral Spastic Cerebral Palsy

Volume 3 ABSTRACT Introduction: Conservative therapy for bilateral spastic cerebral palsy (BSCP) regularly includes a modular orthosis setup with dynamic ankle-foot orthosis (DAFO) and modular shank supply (MSS). Additional effects by this modular supply have not been studied so far. The goal was thus an exploratory investigation of what effects can be expected by supplementing a DAFOwith an additional MSS. Materials and Methods: Ten children with BSCP were fitted with DAFO and MSS. Dynamic elastic shank adaptations (DESAs) and ground reaction force AFOs (GRAFOs) were used, depending on the participants' individual needs. Participants underwent a gait analysis after supply and 3 months later. Data analysis included a descriptive analysis and further statistical testing using a Friedman test and post hoc Wilcoxon rank test. Results: The Gillette Gait Index (GGI) improved significantly with MSS compared with barefoot and DAFO, the Gait Deviation Index (GDI) only comparing DAFO to MSS. However, no further changes had occurred at follow-up, and for the Gait Profile Score (GPS), not at all. Step length, velocity, cadence, stance duration, and step width changed significantly after supply. Kinematic changes developed at ankle, knee, hip, and trunk. However, only minor changes had occurred at follow-up. Conclusions: DAFOs and MSS show positive effects, as observed in spatiotemporal parameters, gait indices, and kinematic data. Most kinematic effects occur at the ankle and knee joint. MSS produces additional effects, with a particular emphasis on the extending effect on the knee in terminal stance. Only minor beneficial effects on kinematic parameters of knee and trunk during swing phase occur after a familiarization phase. The changes in the spatiotemporal parameters imply a slight deterioration. (J Prosthet Orthot. 2021;33:125–132)
Wandering eyes: Eye movements during mind wandering in video lectures

Video lectures are increasingly prevalent, but they present challenges to learners. Students' minds often wander, yet we know little about how mind-wandering affects attention during video lectures. This paper presents two studies that examined eye movement patterns of mind-wandering during video lectures. In the studies, mind-wandering reports were collected by either self-caught reports or thought probes. Results were similar across the studies: mind-wandering was associated with an increased allocation of fixations to the instructor's image. For fixations on the slides, the average duration increased but the dispersion decreased. Moreover, preliminary evidence suggested that fixation duration and dispersion can diminish soon after self-caught reports of mind-wandering. Overall, these findings help advance our understanding of how learners' attention is affected during mind-wandering and may facilitate efforts in objectively identifying mind-wandering. Future research is needed to determine if these findings can extend to other instructional formats.
Mass media campaigns to reduce unnecessary caesarean sections: a systematic review

Introduction The worldwide increase in unnecessary caesarean sections (CSs) is a major global health issue. Mass media campaigns have been used in several countries to reduce this trend. The objectives of this systematic review were to identify, critically appraise and synthesise the findings, including the barriers and enablers, of mass media campaigns directed at lay people to reduce unnecessary CS. Methods We included any study design that reported health communication mass media campaigns directed at lay people with the specific objective of reducing unnecessary CS, created by any agent, in any format. We searched seven electronic databases without language restrictions, from inception to February 2019. Experts in the field were contacted. Results The search yielded 14 320 citations; 50 were selected for full-text reading; and one was included. Six other reports were included. The seven campaigns were conducted in 2009–2017, mostly in Latin America. Most campaigns were independent efforts by non-governmental or activist organisations. Only one campaign conducted formative research and pretested the intervention. All campaigns used indirect communication, mostly through internet channels; two campaigns also used direct communication with the public. None assessed their effects on CS rates. Only two campaigns measured their impacts on participants’ knowledge, attitudes and birth preferences but only in the short term. The main barriers were lack of financial and human resources. The main enablers were the enthusiasm of volunteers, the participation of famous persons/celebrities and the involvement of communication professionals. Conclusions There are few mass media campaigns directed at lay people to reduce CS. Most campaigns did not use key principles recommended for the creation and implementation of health communication interventions, and none assessed their effects in reducing CS rates. If media campaigns can play a role in modifying population views towards CS, there is a need for more rigorous studies including impact assessment. PROSPERO registration number CRD42019120314.
Standard Normal Fetal Lung Volume by MRI Measurement

Background: Pulmonary hypoplasia is a significant decrease in lung volume by any cause in comparison to the normal volume for gestational age. Objectives: To evaluate the application of prenatal magnetic resonance imaging in order to predict pulmonary hypoplasia, measurement of fetal lung volume (FLV) was aimed to establish a reference data in normal fetuses. Patients and Methods: Three hundred forty two fetuses with abnormal ultrasound findings underwent fast spin-echo T2-weighted MR imaging at a single tertiary care hospital (Shahid Faghihi Hospital, Shiraz, Iran). Data of 241 fetuses at 18 - 36 weeks’ gestation without thoracic malformations were obtained for a FLV normative curve. To acquire a best-fit formula for the mean total fetal lung volume based on each gestational week with 95% confidence interval (CI), we used the regression model applied by Rypens et al. This resulted in a formula calculating the expected fetal lung volume based on gestational age. A one-sample t-test was also carried out to compare the mean total fetal lung volume at each gestational week with the expected mean total fetal lung volume predicted by the formula by Rypens et al., Meyers et al., and Osada et al. Results: Normal FLV increased with gestational age as the spread of values. The expected fetal lung volume was derived from the following formula: Fetal lung volume (mL) = 0.002 × (gestational age [GA]2.913), in which GA is gestational weeks. FLV in our population had a more consistent correlation with Japanese fetuses than European or American fetuses. Conclusion: In fetuses with normal lungs, FLV distribution against gestational age is simply measured prenatally with MR imaging. A single universal formula might not be suitable for fetuses worldwide. In our region, acquired data were more consistent with Asian normal values.
Changes in the Weed Seed Bank in Long-Term Establishment Methods Trials under Rice-Wheat Cropping System

The rice–wheat cropping system in the Indo-Gangetic Plains is the backbone of food security in India. In the 1990s, due to the scarcity of resources, the traditional Crop Establishment (CE) method shifted from Conventional Till Puddle Transplanted Rice (CTPTR) to CT Direct Seeded Rice (CTDSR) and Zero-Till DSR (ZTDSR) in paddy; and in wheat, from Conventional Till Wheat (CTW) to Zero Till Wheat (ZTW), with residue retention in rice (RRR) or in both rice and wheat (RRRW). Shift in CE methods led to change in Weed Seed Bank (WSB) dynamics and ultimately affected the weed management program. After five years of field trials, soil samples were drawn as per 2-factors factorial randomized block design. Factor-I comprised 4-CE methods, whereas factor-II consisted of 3-soil depths (0–10, 10–20 and 20–30 cm). Results showed CTPTR-CTW and ZTDSR-ZTW (RRRW) record the highest seed bank (SB) of grasses, sedges and BLWs as total weeds, in general; and predominant weeds like Echinochloa spp. , Ammania baccifera, Commelina benghalensis and Digitaria sanguinalis, in particular. It also showed the higher species richness (DMg) and Shannon–Weaver (H’) indices. CTDSR-CTW and CTDSR-ZTW (RRR) show the lowest WSB and at par with Shannon–Weaver (H’) index; further, lowest species richness (DMg) under CTDSR-CTW. Species Evenness (J’) and Simpson index (λ) vary non-significantly with CE methods. Furthermore, 0–10 cm soil depth showed the highest SB of different category of total weed, predominant weeds as well as higher values of DMg, H’, and λ; whereas reverse trend was observed in Whittaker Statistic (βW). Interaction between CE methods and soil depth revealed most of WSB lying on the top layer in case of ZTDSR-ZTW (RRRW) and CTDSR-ZTW (RRR); while CTPTR-CTW showed almost uniform WSB distribution, and in case of CTDSR-CTW, a gradual decrease in WSB with soil depth.

Minimization of Abnormal Output Voltage Rising for LLC Resonant Converter at Very Light Load

An LLC resonant converter is a very attractive topology for high efficiency and high power density applications, thanks to zero-voltage switching of primary switches and zero-current switching of secondary rectifiers as well as low-voltage stress of the overall components. Its critical drawback is the unintended increase of output voltage beyond the regulation limit at very light load, in spite of much higher switching frequency for low input-to-output voltage gain. To suppress output voltage within the regulation range at very light load, the external capacitor attached across drain–source of primary switches is investigated and the optimal capacitance is designed in this article. Its validity is verified experimentally with the implemented 240-W prototype for flat-panel display application.
Desarrollo de un simulador para la coordinación de drones usando la plataforma SPADE

Currently the use of drones for the execution of different tasks is increasing. This fact generates a need for using mechanisms to manage the control of these aircraft automatically. For that reason this project has developed a simulation tool that allows the control of drones automatically. Furthermore, this implementation merges the capabilities offered by an intelligent agent system along with a simulation environment. The developed tool allows the user to use a union of the SPADE agent system and the AirSim vehicle simulator. An architecture has been implemented to support these two technologies, for the development of applications with models of coordination with intelligent agents and models of learning by reinforcement adapted to drones. The coordination model between agents, in this case adapted to drones, allows the user to perform joined tasks through instant messaging between agents. In the current project an example of coordination between drones has been developed, managing to carry out a series of manoeuvres through the simulation environment using a “following” mode. Regarding the reinforcement learning model developed, it consists of performing actions that involve movements and obtaining a reward from them. This reward assesses the degree of benefit brought into the system to achieve the ultimate goal. As actions are performed, the algorithm learns which actions are most beneficial under determinate states.
Early Chest Compressions Applied to an Out-Of-Hospital Cardio-Pulmonary Arrest Case by an Untrained Savior

Recognizing arrest victim, starting early chest compressions, activating the emergency medical services and knowing the steps of Basic Life Support especially the chest compression for bystanders who witness the sudden collapse of an adult will have positive effects on the mortality of out-of-hospital cardio-pulmonary arrest cases. In present case we discussed a cardiopulmonary arrested patient to whom cardiopulmonary resuscitation was applied by an untrained savior.
Dental Implant Outcomes in Patients with Osteoporosis: A Matched Cohort Study

This study evaluated differences in dental implant outcomes in patients with osteoporosis and their matched controls. Twenty-four patients, who received dental implants at the University of Toronto, were 60+ yrs and had osteoporosis at the time of implant placement, and their controls matched for age, sex and implant related features were examined clinically and radiographically. Clinical and demographic variables recorded at implant placement and follow-up examination, were analyzed. Implant survival rates of 95.1% and 100%, and success rates of 91.4% and 100% were noted in the osteoporosis and control samples respectively. All failures in the osteoporosis sample occurred in the maxilla of a single subject, raising suspicion that these were related to individual problems specific to this subject. Due to the paucity of adverse outcomes and with all the implant failures having occurred in one subject, no relationship of adverse outcomes with clinical and demographic variables could be analyzed.
Students’ acceptance towards blended learning implementation

The objective of the inquiry is to observe students’ acceptance towards blended learning implementation. It focuses on students’ perceptions and attitudes towards using easyclass.com as a learning management tool and face-to-face learning. The case study has been conducted among business students in a private university in Medan, North Sumatera. The research employed a quantitative approach based on the Technological Acceptance Model (TAM), and asked the students to answer a questionnaire. They also were interviewed to acquire insights about the blended learning implementation. The study concludes that the students’ awareness and attitudes were encouraging towards the learning management tools in term of the usefulness and the ease of use. However, negative impressions also were underlined during the interview with the students. In summary, blended learning implementation requires an integrated approach where the learning management system is useful and ease to use. Finally, an active participation from both teachers and students is a must in the blended learning implementation.
Dielectric Sensor System Using TiO2 Nanotubes for Real-Time Detection of Methanol Contamination in Alcoholic Beverages

In this article, a portable sensor system based on a TiO2 nanotube array is described for detecting methanol contamination in alcoholic beverages. TiO2 nanotubes were synthesized on a Ti substrate by using electrochemical anodization technique and Au contacts were deposited over TiO2 nanotubes by vacuum-assisted thermal evaporation technique. The TiO2 nanotube array was sandwiched in-between Ti and Au electrodes, which resulted in a capacitive-type structure of the sensor. The conductive and capacitive changes in the sensor operating at room temperature were then tested for pure ethanol, 10% and 25% methanol-contaminated ethanol, and pure methanol. The sensor exhibited a selective capacitive response toward all methanol-contaminated samples and recovered to its baseline capacitance value in less than 40 s. The dielectric sensor was then integrated with a 9-V, battery-driven, signal-processing circuit having a LED for notifying the information on methanol contamination in an alcoholic beverage. The integrated sensor system was able to detect 10%–100% methanol contamination in alcoholic beverages like whiskeys in less than 3 min.
