A new grid of synthetic spectra for the analysis of [WC]‐type central stars of planetary nebulae

We present a comprehensive grid of synthetic stellar-atmosphere spectra, suitable for the analysis of high-resolution spectra of hydrogen-deficient post-asymptotic giant branch objects hotter than 50 000 K, migrating along the constant luminosity branch of the Hertzsprung–Russell diagram. The grid was calculated with cmfgen, a state-of-the-art stellar atmosphere code that properly treats the stellar winds, accounting for expanding atmospheres in non-local thermodynamic equilibrium, line blanketing, soft X-rays and wind clumping. We include many ionic species that have been previously neglected. Our uniform set of models fills a niche in an important parameter regime, that is, high effective temperatures, high surface gravities and a range of mass-loss values. The grid constitutes a general tool to facilitate determination of the stellar parameters and line identifications and to interpret morphological changes in the stellar spectrum as stars evolve through the central star of planetary nebula phase. We show the effect of major physical parameters on spectral lines in the far-ultraviolet (far-UV), UV and optical regimes. We analyse UV and far-UV spectra of the central star of NGC 6905 using the grid to constrain its physical parameters, and proceed to further explore other parameters not taken into consideration in the grid. This application shows that the grid can be used to constrain the main photospheric and wind parameters, as a first step towards a detailed analysis. The full grid of synthetic spectra, comprising of far-UV, UV, optical and infrared spectral regions, is available online.
TOTAL PHENOLICS, FLAVONOIDS AND IN VITRO ANTIOXIDANT ACTIVITY OF NYMPHAEA PUBESCENS WILD RHIZOME

Antioxidant activity of rhizome of Nymphaea pubescens was studied for its free radical scavenging property on different in vitro models viz, DPPH, hydroxyl, superoxide, ABTS and reducing power by using methanol extract. Total phenolic and flavonoid contents were estimated. In vitro antioxidant activity revealed that the methanol extract showed more potent activity. In vitro antioxidant activity was compared with standard ascorbic acid/ trolox.
Factuality Checking in News Headlines with Eye Tracking

We study whether it is possible to infer if a news headline is true or false using only the movement of the human eyes when reading news headlines. Our study with 55 participants who are eye-tracked when reading 108 news headlines (72 true, 36 false) shows that false headlines receive statistically significantly less visual attention than true headlines. We further build an ensemble learner that predicts news headline factuality using only eye-tracking measurements. Our model yields a mean AUC of 0.688 and is better at detecting false than true headlines. Through a model analysis, we find that eye-tracking 25 users when reading 3-6 headlines is sufficient for our ensemble learner.
When the entropy has no maximum: A new perspective on the instability of the first-order theories of dissipation

The first-order relativistic fluid theories of dissipation proposed by Eckart and Landau-Lifshitz have been proved to be unstable. They admit solutions which start in proximity of equilibrium and depart exponentially from it. We show that this behaviour is due to the fact that the total entropy of these fluids, restricted to the dynamically accessible states, has no upper bound. As a result, these systems have the tendency to constantly change according to the second law of thermodynamics and the unstable modes represent the directions of growth of the entropy in state space. We, then, verify that the conditions of stability of Israel and Stewart's theory are exactly the requirements for the entropy to have an absolute maximum. Hence, we explain how the instability of the first-order theories is a direct consequence of the truncation of the entropy current at the first order, which turns the maximum into a saddle point of the total entropy. Finally, we show that recently proposed first-order stable theories, constructed using more general frames, do not solve the instability problem by providing a maximum for the entropy, but, rather, are made stable by allowing for small violations of the second law.
Sketch-Guided Scenery Image Outpainting

The outpainting results produced by existing approaches are often too random to meet users’ requirements. In this work, we take the image outpainting one step forward by allowing users to harvest personal custom outpainting results using sketches as the guidance. To this end, we propose an encoder-decoder based network to conduct sketch-guided outpainting, where two alignment modules are adopted to impose the generated content to be realistic and consistent with the provided sketches. First, we apply a holistic alignment module to make the synthesized part be similar to the real one from the global view. Second, we reversely produce the sketches from the synthesized part and encourage them be consistent with the ground-truth ones using a sketch alignment module. In this way, the learned generator will be imposed to pay more attention to fine details and be sensitive to the guiding sketches. To our knowledge, this work is the first attempt to explore the challenging yet meaningful conditional scenery image outpainting. We conduct extensive experiments on two collected benchmarks to qualitatively and quantitatively validate the effectiveness of our approach compared with the other state-of-the-art generative models.
Hematological parameters in champion of Brazilian jiu‐jitsu paradesport: Case study

The behavior of biochemical and immunological parameters investigated in the field conditions in athletes is important to influence in the management of recovery and disease prevention as well as, to support the training program, as well as to improve the physical conditioning associated with health and performance. However, for amputee athletes, Brazilian jiu‐jitsu paradesport practitioners, there are no published data to date. Thus, the objective of this case study was to quantify the magnitude of biochemical, hematological, and urinary alterations after a simulated fight session in elite athlete with world titles. Outcomes were obtained through blood analysis of samples collected at four different moments (M1‐fasting; M2—1.5 hr after caloric intake; M3—Immediately after the simulated fight; M4—24 hr after the simulated fight). Responses triggered by the simulated fight between baseline and after 24 hr were found to increase in monocyte (100%), neutrophil (20%), and insulin (57%) concentrations, while reductions were observed in eosinophils (−50%), lymphocytes (−26.6%), platelets (−22%), cortisol (−50%), and creatine phosphokinase (−45.2%). After 24 hr lactate values returned to baseline levels. The different changes in biochemical and hematological parameters observed constitute responses to acute physical exercise and were according to the level of the high performance athlete. From these data it will be possible to evaluate the periodization, training load, and recovery techniques according to the individual response verified. In addition, these data may be used for comparison purposes within this specific sport, whose literature is still limited.
Merge-and-Shrink Task Reformulation for Classical Planning

The performance of domain-independent planning systems heavily depends on how the planning task has been modeled. This makes task reformulation an important tool to get rid of unnecessary complexity and increase the robustness of planners with respect to the model chosen by the user. In this paper, we represent tasks as factored transition systems (FTS), and use the merge-and-shrink (M&S) framework for task reformulation for optimal and satisficing planning. We prove that the flexibility of the underlying representation makes the M&S reformulation methods more powerful than the counterparts based on the more popular finite-domain representation. We adapt delete-relaxation and M&S heuristics to work on the FTS representation and evaluate the impact of our reformulation.
Rain prediction using fuzzy rule based system in North-West malaysia

The warm and humid condition is the characteristic of Malaysia tropical climate. Prediction of rain occurrences is important for the daily operations and decisions for the country that rely on agriculture needs. However predicting rainfall is a complex problem because it is effected by the dynamic nature of the tropical weather parameters of atmospheric pressure, temperature, humidity, dew point and wind speed. Those parameters have been used in this study. The rainfall prediction are compared and analyzed. Fuzzy Logic and Fuzzy Inference System can deal with ambiguity that often occurred in meteorological prediction; it can easily incorporate with expert knowledge and empirical study into standard mathematical. This paper will determine the dependability of Fuzzy Logic approach in rainfall prediction within the given approximation of rainfall rate, exploring the use of Fuzzy Logic and to develop the fuzzified model for rainfall prediction. The accuracy of the proposed Fuzzy Inference System model yields 72%
Regularizing effect for conservation laws with a Lipschitz convex flux

This paper studies the smoothing effect for entropy solutions of conservation laws with general nonlinear convex fluxes on $\mathbb{R}$. Beside convexity, no additional regularity is assumed on the flux. Thus, we generalize the well-known $\mathrm{BV}$ smoothing effect for $\mathrm{C}^2$ uniformly convex fluxes discovered independently by P. D. Lax and O. Oleinik, while in the present paper the flux is only locally Lipschitz. Therefore, the wave velocity can be dicontinuous and the one-sided Oleinik inequality is lost. This inequality is usually the fundamental tool to get a sharp regularizing effect for the entropy solution. We modify the wave velocity in order to get an Oleinik inequality useful for the wave front tracking algorithm. Then, we prove that the unique entropy solution belongs to a generalized $\mathrm{BV}$ space, $\mathrm{BV}^\Phi$.
Singing One's Way to Self-Regulation: The Role of Early Music and Movement Curricula and Private Speech

Research Findings: Although the role of language and private speech in the development of behavioral self-regulation has been studied, relations between behavioral self-regulation and children's experiences with other symbolic systems, such as music, have not yet been explored. Eighty-nine 3- and 4-year-old children (42 of whom had been enrolled in Kindermusik music and movement classes, and 47 demographically similar children who had not experienced structured early childhood music classes) completed a battery of laboratory self-regulation tasks and a selective attention task during which their private speech was reliably transcribed and categorized. Children currently enrolled in Kindermusik classes showed better self-regulation than those who were not currently enrolled (d = .41), and they also used more relevant private speech during the selective attention task (d = .57), a verbal strategy that was positively related to performance. Children exposed to the music program were also more likely to engage in the facilitative strategy of singing/humming to themselves during a waiting period in which they had to inhibit their desire to examine a gift, and they were less likely to call out socially to the experimenter, a strategy negatively associated with performance and self-regulation. Practice or Policy: Implications for early childhood education are discussed.
Missed opportunities? The development of human welfare in Western Europe, 1913-1950

Income per capita suggests that the period 1913-1950 is one of missed opportunities for improving living standards in Europe. However, life in Europe during these years improved significantly, as citizens began experiencing dramatic declines in mortality, working time and inequality thanks to (among others) the spread of modern medicine and the introduction of the 8-hour working day. To measure the contribution of these aspects to broader welfare, I apply a new utility-based framework that, contrary to previous composite indices such as the Human Development Index, allows for a welfare analysis directly comparable to GDP across countries and time. The results using the new measure shows that income per capita underestimates welfare growth significantly (up to five percent annually). Moreover, with this indicator cross-country differences in living standards are much larger and more persistent than other composite indices of well-being imply. These findings call for a reappraisal of the evolution of living standards during the period 1913-1950 and, more generally, of the measurement of multi-dimensional welfare in historical contexts.
Pediatric Thoracic Empyema—Outcomes of Intrapleural Thrombolytics: Ten Years of Experience

Introduction. Pediatric thoracic empyema is a special entity with increasing frequency. Consensus regarding the best management strategy is still evolving. We describe our single-center 10-year experience adopting intrapleural thrombolytics using tissue plasminogen activator as first-line treatment following failure of simple thoracostomy drainage techniques. Methods. Observational prospective study included all children from 1 day to 18 years admitted for parapneumonic effusion and treated with intrapleural thrombolytics. Results. From January 2008 to December 2018, 95 patients were treated by intrapleural thrombolytics for different stages of empyema thoracis. Number of thrombolytic doses required is 2.1 (range = 1-3), and mean amount of drainage is 1050 mL (range = 400-2500 mL). Mean total days of hospitalization is 7.3 days. Complete re-expansion was the primary outcome in 94 patients (98.9%). Conclusion. Intrapleural thrombolytics in complicated pediatric thoracic empyema results in excellent outcome and should be encouraged particularly in limited resource countries.
Lower extremity revascularization via endovascular and surgical approaches: A systematic review with emphasis on combined inflow and outflow revascularization

This review is intended to help clinicians and patients understand the present state of peripheral artery disease, appreciate the progression and presentation of critical limb ischemia/chronic limb-threatening ischemia, and make informed decisions regarding inflow and outflow endovascular revascularization and surgical treatment options within the context of current debates in the medical community. A controlled literature search was performed to obtain research on outcomes of critical limb ischemia patients undergoing complete leg revascularization for peripheral artery disease inflow and outflow disease. Data for this review were identified by queries of medical and life science databases, expert referral, and references from relevant papers published between 1997 and 2019, resulting in 48 articles. The literature review herein indicates that endovascular revascularization—including ballooning, stenting, and atherectomy—is an effective peripheral artery disease therapy for both above the knee and below the knee disease, and can safely and effectively treat both inflow and outflow disease. As such, it plays a leading role in the therapy of lower extremity artery disease.
Errors within the total laboratory testing process, from test selection to medical decision-making – A review of causes, consequences, surveillance and solutions

Laboratory analyses are crucial for diagnosis, follow-up and treatment decisions. Since mistakes in every step of the total testing process may potentially affect patient safety, a broad knowledge and systematic assessment of laboratory errors is essential for future improvement. In this review, we aim to discuss the types and frequencies of potential errors in the total testing process, quality management options, as well as tentative solutions for improvement. Unlike most currently available reviews on this topic, we also include errors in test-selection, reporting and interpretation/action of test results. We believe that laboratory specialists will need to refocus on many process steps belonging to the extra-analytical phases, intensifying collaborations with clinicians and supporting test selection and interpretation. This would hopefully lead to substantial improvements in these activities, but may also bring more value to the role of laboratory specialists within the health care setting.
GENETIC DIVERSITY ANALYSIS IN SESAME ( Sesamum indicum ) USING MORPHOLOGICAL , BIOCHEMICAL AND MOLECULAR TECHNIQUES

Institute of Biotechnology, Acharya N.G Ranga Agricultural University, Rajendranagar, Andhra Pradesh 500 030, India. ABSTRACT: Genetic diversity of Sesame germplasm was estimated with morphological, biochemical and molecular approaches using 23 accessions collected from local areas of Andhra Pradesh, India. Correlation studies were conducted for 13 quantitative and 2 qualitative morphological parameters. Euclidian similarity matrix for morphological data was computed between observable distances and dendrogram (r = 0.79). Cluster analysis revealed two major clusters. Biochemical analysis through Nuclear Magnetic Resonance obtained 37-47% of oil content. Fatty acid estimation with Gas Chromatography revealed four principle fatty acids, palmitic, steric, oleic and linoleic acids with highest linoleic acid content was reported. Molecular analysis using SSR markers revealed 4 polymorphic primers. A total of 14 alleles were detected at four loci with an average of 3.5 alleles per locus. The pair wise similarity based on Dice coefficient ranged from 0 to 1. The correlation coefficient (r) computed between observed distances and dendrogram was 0.77 which indicates a good fit. Their genetic distance ranged from 0.1-0.9 which is wider than their phenotypic distance ranged from 0.2-0.7. MXCOMP between phenotypic and genotypic data gave the correlation coefficient value (r) = 0.12 which was showing less congruency. For sesame germplasm improvement, characterization and breeding programs these results have an important implication.
Ilkka EMF exposure analysis for a compact multi-band 5 G antenna

The fifth generation (5G) wireless communication systems are projected to work at millimeter wave (mm-wave) frequency bands that would bring new challenges with the implementation of antennas and safety level of electromagnetic field exposures. In this paper, a new design of 5G mmwave antenna for multi-frequency bands has been introduced. The antenna is small enough and has a form factor that can be easily fit into the current available mobile handset devices. The proposed antenna covers all the nominated frequency bands by the FCC for 5G communications and has good radiation performances at 28GHz, 37GHz, 39GHz, and 64–71GHz. The electromagnetic field exposure to the human head model has been studied by means of numerical simulation for all above frequency bands. The feature of our proposed antenna is that all the frequency bands for the 5th generation mobile handset will be available in a single and simple antenna structure; hence, analysis of EMF exposure in a wide range of frequency can be done on a single antenna design.
The Role of Primary Tumor Resection in Patients with Pleural Metastasis Encountered at the Time of Surgery

Background Evidence is lacking on whether the resection of lung parenchymal cancer improves the survival of patients with unexpected pleural metastasis encountered during surgery. We conducted a single-center retrospective study to determine the role of lung resection in the long-term survival of these patients. Methods Among 4683 patients who underwent lung surgery between 1995 and 2014, 132 (2.8%) had pleural metastasis. After excluding 2 patients who had incomplete medical records, 130 patients’ data were collected. Only a diagnostic pleural and/or lung biopsy was performed in 90 patients, while the lung parenchymal mass was resected in 40 patients. Results The mean follow-up duration was 29.8 months. The 5-year survival rate of the resection group (34.7%±9.4%) was superior to that of the biopsy group (15.9%±4.3%, p=0.016). Multivariate Cox regression analysis demonstrated that primary tumor resection (p=0.041), systemic treatment (p<0.001), lower clinical N stage (p=0.018), and adenocarcinoma histology (p=0.009) were significant predictors of a favorable outcome. Interestingly, primary tumor resection only played a significant prognostic role in patients who received systemic treatment. Conclusion When pleural metastasis is unexpectedly encountered during surgical exploration, resection in conjunction with systemic treatment may improve long-term survival, especially in adenocarcinoma patients without lymph node metastasis.

A Synopsis of Input Modalities for In-Vehicle Infotainment and Consumption of Interactive Media

Connected vehicles collect and share data by communicating with road infrastructure, with each other, the web, IoT systems, and with their occupants’ personal devices. Part of this data is presented to drivers via a multitude of interactive devices and systems. Thus, one challenge that arises in such a complex environment is effective and safe operation of the various interactive systems, e.g., the in-vehicle infotainment (IVI). In this paper, we present a synopsis of input modalities from the literature of automotive user interfaces (AutoUIs) for media consumption inside connected vehicles.

Interplay between Information Theory and Functional Analysis

My research interests gravitate towards understanding the fundamental properties of various information processing tasks, such as data compression, data transmission, data hiding (secrecy), and learning from data (inference). While my previous works often started from an information theorist’s perspective, some of the topics I explored (such as randomness generation and sampling) have parallels in computer science and probability/statistics.
