A Self Balancing Space Vector PWM for Z Source T Multilevel Inverter

This paper presents a Z Source -T shape Neurtal point Diode Clamped (NPC) Multi Level Inverter (MLI) power conversion system (Z-T-NPC-MLI) with the aid of New Space Vector PWM (SVPWM) scheme. The proposed impedance source (Z-Source) MLI associations the advantages of boosting operations with DC to AC power conversions. There are many MLI Z-Source research papers for concentrating the desired voltage generations with minimal switching and conduction losses. Nevertheless, the reported research on Z-NPC-MLI SVPWM has dealt with reduction of Shoot through (ST) options and voltage boosting operations enhancement; those are does not address the neutral point fluctuation (NPF) problems on the DCLink. This paper offers improved SVPWM strategies for Zsource NPC-MLI with minimal ST state options. The proposed SVPWM exploits the redundancy switching vector option for both ST and regular switching (non-ST), which offers self-control to NP (DC-link capacitor) balancing. With this benefit of this selfcontrol DC-link capacitors balancing, the inverter able to maintain their output quarter symmetry waveform and henceforth the harmonic spectra for the voltage and current waveform is maintained lesser. The proposed SVPWM for Z-TNPC-MLI is simulated in MATLAB/SIMULINK 2011.b software environment, and the results confirm the advantages of the proposed inverter and its simplified PWM scheme. The experimentation is also performed for 1kW three-phase Z-TNPC-MLI system using sparten-6 FPGA processor. The experimental results are confirmed the simulation results.

A Methodology for Attributing the Role of Climate Change in Extreme Events: A Global Spectrally Nudged Storyline

<p>Extreme weather events are generally associated with unusual dynamical conditions, yet the signal-to-noise ratio of the dynamical aspects of climate change that are relevant to extremes appears to be small, and the nature of the change can be highly uncertain. On the other hand, the thermodynamic aspects of climate change are already largely apparent from observations, and are far more certain since they are anchored in agreed-upon physical understanding. The storyline method of extreme event attribution, which has been gaining traction in recent years, quantitatively estimates the magnitude of thermodynamic aspects of climate change, given the dynamical conditions. There are different ways of imposing the dynamical conditions. Here we present and evaluate a method where the dynamical conditions are enforced through global spectral nudging towards reanalysis data of the large-scale vorticity and divergence in the free atmosphere, leaving the lower atmosphere free to respond. We simulate the historical extreme weather event twice: first in the world as we know it, with the events occurring on a background of a changing climate, and second in a &#8216;counterfactual&#8217; world, where the background is held fixed over the past century. We describe the methodology in detail, and present results for the European 2003 heatwave and the Russian 2010 heatwave as a proof of concept. These show that the conditional attribution can be performed with a high signal-to-noise ratio on daily timescales and at local spatial scales. Our methodology is thus potentially highly useful for realistic stress testing of resilience strategies for climate impacts, when coupled to an impact model. </p>
Mental health, substance use and viral load suppression in adolescents receiving ART at a large paediatric HIV clinic in South Africa

Introduction: There are few data on the prevalence of mental health problems among adolescents living with HIV in low- and middle-income countries and the evidence on associations between mental health problems and viral load suppression is inconsistent. We assessed the prevalence of mental health problems among adolescents receiving antiretroviral therapy (ART) at a large paediatric HIV clinic in South Africa and examined associations between mental health problems and viral load suppression. Methods: We implemented routine mental health screening at Rahima Moosa Mother and Child Hospital in Johannesburg. Adolescents aged 10-19 years were offered screening for depression (Patient Health Questionnaire-9 [PHQ-9]), suicide (Adolescent Innovations Project [AIP]-handbook), anxiety (General Anxiety Disorder-7 [GAD-7]), trauma (Primary Care PTSD Screen for DSM-5 [PC-PTSD-5]), and substance use (CAGE Adapted to Include Drugs [CAGE-AID]) at each routine HIV care visits. We assessed screening outcomes between February 1, 2018, and January 1, 2020 and calculated odds ratios for associations between positive screening outcomes and unsuppressed viral load (>400 HIV-RNA copies/ml). Results: Out of 1,203 adolescents who attended the clinic, 1,088 (90.4%) were screened at a median age of 13 years (IQR 10-15). In total, 97 (8.9%) screened positive: 48 (4.4%) for depression (PHQ-9 [≥]10), 29 (2.8%) for suicidal concern, 24 (2.2%) for anxiety (GAD-7 [≥]10), 38 (3.2%) for trauma (PC-PTSD-5 [≥]3), and 18 (1.7%) for substance use (CAGE-AID [≥]2). Positive screening for depression (aOR 2.39, 95% CI 1.02-5.62), trauma (aOR 3.18, 95% CI 1.11-9.07), substance use (aOR 7.13, 95% CI 1.60-31.86), or any mental health condition (aOR 2.17, 95% CI 1.17-4.02) were strongly associated with unsuppressed viral load. Conclusions: HIV-positive adolescents who are affected by mental health or substance use problems are a highly vulnerable population, who merit specific clinical attention. Strategies for screening and management of mental health and substance use problems in adolescents on ART in low- and middle- income countries need to be developed and evaluated.
Adverse Events in Surgical Neurology: The Novel Therapy-Disability-Neurology (TDN) Grade

Background The most widely used classifications of adverse events (AE) in surgical neurology assign a grade to AE that depends on the therapy used to treat them or on new neurologic deficits. Both concepts have substantial shortcomings in grading AE severity. We present a novel multidimensional approach to this challenge and aim at validating the new grading system. Methods The new Therapy-Disability-Neurology (TDN) grading system classifies AE into five grades, depending on the associated therapy, disability, and neurologic deficits. We conducted a two-center study on 6071 interventions covering the whole neurosurgical spectrum with data prospectively recorded between January 2013 and September 2019 at the University Hospital Zurich (USZ) and at the Fondazione IRCCS Istituto Neurologico Carlo Besta (FINCB). Findings Using data from USZ, a positive correlation was found between the severity of AE and the length of hospital stay (LOS) as well as treatment cost. Each grade was associated with a greater deterioration of the Karnofsky Performance Status Scale (KPS) at discharge and at follow-up. Additionally, there was a correlation between the severity of AE and absolute KPS values. When using the same methods on an external validation cohort from FINCB, correlations between the grade of AE, LOS, and KPS at discharge were even more pronounced. Interpretation Our results suggest that the TDN grade is consistent with clinical and economic repercussions of AE and thus reflects AE severity. It is objective, practical, easily interpreted, and enables comparison between different medical centers. The TDN grade will constitute an important step forward towards a more precise and standardized documentation of AE and ultimately lead to a more critical and patient-centered appraisal of process and outcome measures in surgical neurology.

Molecular Tracing of SARS-CoV-2 in Italy in the First Three Months of the Epidemic

The aim of this study is the characterization and genomic tracing by phylogenetic analyses of 59 new SARS-CoV-2 Italian isolates obtained from patients attending clinical centres in North and Central Italy until the end of April 2020. All but one of the newly characterized genomes belonged to the lineage B.1, the most frequently identified in European countries, including Italy. Only a single sequence was found to belong to lineage B. A mean of 6 nucleotide substitutions per viral genome was observed, without significant differences between synonymous and non-synonymous mutations, indicating genetic drift as a major source for virus evolution. tMRCA estimation confirmed the probable origin of the epidemic between the end of January and the beginning of February with a rapid increase in the number of infections between the end of February and mid-March. Since early February, an effective reproduction number (Re) greater than 1 was estimated, which then increased reaching the peak of 2.3 in early March, confirming the circulation of the virus before the first COVID-19 cases were documented. Continuous use of state-of-the-art methods for molecular surveillance is warranted to trace virus circulation and evolution and inform effective prevention and containment of future SARS-CoV-2 outbreaks.
Topic Analysis of Traditional and Social Media News Coverage of the Early COVID-19 Pandemic and Implications for Public Health Communication

Abstract Objective: To characterize and compare early coverage of coronavirus disease 2019 (COVID-19) in newspapers, television, and social media, and discuss implications for public health communication strategies that are relevant to an initial pandemic response. Methods: Latent Dirichlet allocation (LDA), an unsupervised topic modeling technique, analysis of 3271 newspaper articles, 40 cable news shows transcripts, 96,000 Twitter posts, and 1000 Reddit posts during March 4-12, 2020, a period chronologically early in the timeframe of the COVID-19 pandemic. Results: Coverage of COVID-19 clustered on topics such as epidemic, politics, and the economy, and these varied across media sources. Topics dominating news were not predominantly health-related, suggesting a limited presence of public health in news coverage in traditional and social media. Examples of misinformation were identified, particularly in social media. Conclusions: Public health entities should use communication specialists to create engaging informational content to be shared on social media sites. Public health officials should be attuned to their target audience to anticipate and prevent spread of common myths likely to exist within a population. This may help control misinformation in early stages of pandemics.
Eye movement recordings during reading tasks in children with mixed dyslexia

Introduction and Methodology: In order to better understand how mixed dyslexia (MD) manifests in the Spanish language, we studied the patterns in eye movements (EM) and errors of omission, inversion, transposition, substitution, addition, semantic change and lexicalization, committed during reading tasks for words, pseudowords and paragraphs, in 30 fourth grade children (15 MD and 15 controls). Results and Conclusion: We found statistically significant differences between cases and controls, where children with MD showed more substitution, omission and repetition errors, together with more fixations and single saccades. These differences result in decreased reading speed and comprehension level of
Conus coronatus and Conus frigidus Venom: A New Source of Conopeptides with Analgesic Activity

Background: Cone snails are a natural source of complex peptides with analgesic properties called conotoxins. These peptides are secreted in a complex venomic mixture and are predominantly smaller than 5 kDa. The present study aimed to document the analgesic activity of two species of Conus coronatus (C. coronatus) and Conus frigidus (C. frigidus) venom collected off the Iranian coast in a mouse behavioral test. Methods: Conotoxin containing fractions was extracted from the venom ducts and initially purified by column chromatography. The analgesic effect of the fractions was determined on formalin pain model and hot-plate test. Results: The results led to the identification of four fractions with analgesic activity in C. coronatus and two in C. frigidus. Only one fraction was able to reduce the flinching and licking in both acute pain and chronic pain phases of the formalin test. Moreover, the activity of this fraction remained 30 minutes on the hot-plate test. Purification of the fractions was carried out by RP-HPLC. LC-ESI-MS analysis of the fractions showed that the conotoxins of the analgesic fraction had molecular weights not previously reported. Conclusion: The findings give insight into the venom of two previously under-investigated Conus species and reveal the therapeutic potential of the containing conopeptides.
LONG-TERM STUDY OF APPARENT SURVIVAL IN PACIFIC GOLDEN-PLOVERS AT A WINTERING GROUND ON OAHU, HAWAIIAN ISLANDS

Abstract We monitored the apparent survival of territorial and nonterritorial Pacific Golden-Plovers (Pluvialis fulva) for 20 consecutive nonbreeding seasons at a wintering ground within Bellows Air Force Station (BAFS) on the eastern shore of Oahu, Hawaii. Territorial birds were especially site-faithful from season to season, and each surviving individual reoccupied the same territory held in previous seasons. On average, territorial birds were resighted for about twice as many postbanding seasons (4.2) as nonterritorial birds (1.8). Open-population modeling indicated that apparent survival varied by age and territorial status. Our most parsimonious model estimated apparent annual survival rates in territorial plovers as 0.90 for young birds (age determined from retained juvenal primaries) from their first through their second wintering season, and 0.80 for adults over numerous seasons. For nonterritorial plovers, the corresponding values were 0.82 and 0.67, respectively. Despite lower apparent survival in nonterritorial plovers, it remains uncertain whether nonterritoriality actually results in shorter life spans. Some surviving nonterritorial birds may have gone undetected (detection probability of 0.70) because of permanent emigration from the study area. Given strong site-fidelity of territorial birds and the relative certainty of detecting them (probability = 1.0), we regarded the disappearance of a plover from its territory as an indicator of mortality. From last-recorded sightings, we concluded that territorial birds died with about equal frequency during the nonbreeding and breeding seasons. Because the latter is of much shorter duration, time-relative hazards were greatest while birds were away from the wintering grounds. Winter mortality was caused by accidents (collisions with overhead wires and other obstructions), and probable predation by owls. We estimated mean additional life expectancy among territorial plovers at 5.1 years for first-year birds, and 4.5 years for unknown-age adults. The oldest known-age individual was a male that lived 13 years 10 months; in adults of uncertain ages, one male survived to a minimum age of 18 years 10 months, and two females to at least 17 years 10 months. Pacific Golden-Plovers wintering at BAFS, especially territorial birds, demonstrated relatively high rates of apparent survival combined with adaptability for coexistence with humans in an urban environment.
Effect of Replacing Live Food with Formulated Feed on Reproductive Performance of Freshwater Angelfish, Pterophyllum scalare (Shcultze, 1823)

The combined effect of live food (LF) and formulated feed (FF) on reproductive performance of Pterophyllum scalare was studied. Mosquito larvae were used as live food in addition to formulated feed which contained 50% protein and 12% lipid. The experiment was arranged as a completely randomized design (CRD) with six replicates for each treatment: P. scalare were fed with formulated feed and/or live food: T1 (100% FF), T2 (75% FF and 25% LF), T3 (50% FF and 50% LF), T4 (25% FF and 75% LF) and T5 (100% LF). Relative fecundity, egg and oil globule diameter was significantly higher (P < 0.05) in T4 and T5 diets whereas inter spawning interval was lower in T3, T4, and T5 diets. Similarly hatching percentages were significantly higher with diets T3, T4, and T5. There were no significant differences observed between treatments on relative hatchling number, hatchling length, and weight. No significant difference was observed for egg and whole body composition of P. scalare fed with different diets. However there was a significant difference between treatments on fatty acid profile. It was concluded that live food can be replaced by up to 25-50% formulated feed without compromising reproductive performance of P. scalare.

The Effect of Oral Health Educational Intervention Program among Mothers of Children aged 1-6, Based on the Theory of Planned Behavior

Statement of the Problem: Oral self- care is an important aspect of lifestyle and a serious public health issue. Purpose: This study aimed to evaluate the effect of an educational program based on the theory of planned behavior (TPB) on the mothers and children’s oral self-care behaviors. Materials and Method: This quasi-experimental study was conducted on 148 mothers and their children (1–6 years) who referred to the health centers of Tabriz, Iran ; divided into two groups of intervention (n=74) and control (n=74). Data were collected through a questionnaire that included demographic characteristics, oral self-care behaviors, and structures of TPB. Both groups completed questionnaires before, immediately, 3 and 6 months after the intervention. The experimental group received three educational sessions, each session held for 120 minutes. The educational methods such as lectures, group discussion, and demonstrations were used. Data were analyzed using SPSS (ver18) software and Chi-square, Independent samples t-test and repeated measure ANOVA at the significant level of < 0.05. Results: Before the intervention, there were no statistically significant differences between both groups in oral self –care behaviors and structures of TPB (p> 0.05). Immediately, 3 and 6 months after the intervention the mean scores of oral self-care behavior presented a significant increase in both mothers and their children in the intervention group (p< 0.001). Six months after the intervention, brushing children’s teeth twice a day increased significantly from 8.1% (6/74) to 55.4% (41/74) in the experimental group (p< 0.001). At immediately, 3, and 6 months after the intervention, the mean scores of mothers’ attitude, subjective norm, perceived behavioral control and intention towards the children’s oral health were significantly increased in the experimental group compared to the control group (p< 0.001). Conclusion: According to the results of this study, intervention based on the theory of planned behavior promotes the oral self-care behavior both in mothers and in their children.

Genetics of Hordeum chilense– Current Status

Hordeum chilense, a South-American wild barley, is being used in cereal breeding because of its good crossability with both wild and cultivated Triticeae species. Amphiploids and chromosome addition lines of H. chilense in common and durum wheats have been obtained as a means to transfer desirable agronomic characters from wild barley to wheat. No allosyndetic pairing has been detected in diverse hybrids involving H. chilense. Several biochemical markers have been associated with the seven chilense chromosome pairs. New approaches are necessary to transfer genes from H. chilense to cereals.
A FUZZY MODEL REFERENCE LEARNING CONTROLLER OF ASMES TO IMPROVE TRANSIENT POWER SYSTEM STABILITY

The power system models for transient stability studies are nonlinear and complex. And theirs parameters change with time, slowly due to environmental effects or rapidly due to faults. It is preferable that the control technique in this system possesses robustness for various fault conditions and disturbances. Many kinds of control techniques with using Advanced Super-conducting Magnetic Energy Storage (ASMES) to improve power system stability have been proposed. While fuzzy controller has proven its value in some applications, the researches applying fuzzy controller with ASMES actively reported. But it is sometimes difficult to specify the rule base for some plants, or the need could arise to tune the rule-base parameters if the plant changes. In order to solve such problems, the Fuzzy Model Reference Learning Controller (FMRLC) is proposed. This paper investigates multiinputs multi-outputs FMRLC for time-variant nonlinear system. This provides the motivation for adaptive fuzzy control, where the focus is on the automatic on-line synthesis and tuning of fuzzy controller parameters (i.e., the use of on-line data to continually learn the fuzzy controller which will ensure that the performance objectives are met). Simulation results show that the proposed robust controller is able to work with nonlinear power system (i.e., single machine connected at infinite bus), under various fault conditions and significant disturbances.
