The New Novel Discrete Distribution with Application on COVID-19 Mortality Numbers in Kingdom of Saudi Arabia and Latvia

This paper aims to introduce a superior discrete statistical model for the coronavirus disease 2019 (COVID-19) mortality numbers in Saudi Arabia and Latvia. We introduced an optimal and superior statistical model to provide optimal modeling for the death numbers due to the COVID-19 infections. This new statistical model possesses three parameters. This model is formulated by combining both the exponential distribution and extended odd Weibull family to formulate the discrete extended odd Weibull exponential (DEOWE) distribution. We introduced some of statistical properties for the new distribution, such as linear representation and quantile function. The maximum likelihood estimation (MLE) method is applied to estimate the unknown parameters of the DEOWE distribution. Also, we have used three datasets as an application on the COVID-19 mortality data in Saudi Arabia and Latvia. These three real data examples were used for introducing the importance of our distribution for fitting and modeling this kind of discrete data. Also, we provide a graphical plot for the data to ensure our results.
Bend pressure drop experiments compared with Fluent

In the present study, experimental data for bend pressure drop were collected from a pilot plant test loop with a pipe diameter of 53 mm. The experiments were performed at three different efflux volumetric concentrations (0%, 3·94% and 8·82%) of 448·5μm silica sand particles and for each concentration the flow velocity was varied from 1·78 to 3·56 m/s. Pressure drops were measured using a multi-tube inverted U-tube manometer assembly, with separation chambers to prevent blockage of the connecting tubes. It was observed that pressure drop along the pipe bend increases with flow velocity and particle concentration. The experimental data for bend pressure drop collected in the present study have been compared with threedimensional computational fluid dynamics (CFD) modelling by running the commercial CFD code Fluent, and show good agreement (within a percentage deviation of ±10%). Modelling results indicate that the velocity and concentration distribution of solids become more uniform downstream, and the pre.
The Incidence of Dysarrhythmias, Their Types and Outcomes in Patients Hospitalized with COVID -19

Background: COVID-19 infection started in China and became a pandemic, the SARS-CoV-2 virus mainly affects the respiratory system but can insult the cardiovascular system as well, higher rate of cardiac arrhythmias noted during the pandemic, and many studies showed that COVID-19 (especially hospitalized patients) can develop different types of arrhythmias which cause higher mortality rate. Objective: To assess the incidence of dysrhythmias and their types and outcomes in hospitalized patients with COVID-19 in Erbil city. Patients and Methods: Patients with documented COVID-19 infection admitted in Erbil Teaching Hospital respiratory care unit and coronary care unit from 1-8-2020 to 30-10-2020 had been included (255 patients) in this cross-sectional study, demographic data, and outcomes were reported, the ECG analyzed by cardiologists and the type of arrhythmia documented. Results: Mean age was 47±12 years, 61% of the patients were male, 25% of them had previous cardiac diseases, 20% diabetes, 16% multiple comorbidities, 8% hypertension, 8% obesity and 23% had no comorbidities, 20.7% of in-hospital patients developed dysrhythmias, 5.9% of them developed sinus tachycardia, 4.7% atrial fibrillation, 3.9% ventricular premature contractions, 2% ventricular fibrillation, 1.9% ventricular tachycardia and 1.9% heart blocks. Most of the patients who developed ventricular arrhythmias, atrial fibrillation, and heart block had previous comorbidities 82%, 62%, and 80% respectively. Arrhythmias caused a higher in-hospital mortality rate (39.6% versus 21.7%) especially among male patients (mortality rate in male patients 43% compared with female patients 33%). Conclusion: Most of the admitted cases were male. Most of them had comorbidities especially previous cardiac diseases. Sinus tachycardia, atrial fibrillation, and ventricular extra-systoles were the most frequent arrhythmias. The mortality rate was increased by arrhythmias mainly in male patients.

Estimation of wire extension length using neural network in MIG welding

Measuring arc length is important to obtain good welding quality in spite of variation of torch height. Therefore, it is necessary to detect arc behaviour in the transient state in addition to the steady state. For this purpose, this paper proposes neural network models which output the present wire extension from the data relating to wire melting, such as welding current, current pickup voltage and wire feed rate in every sampling period. Since performance of the neural network model depends on threshold functions, authors investigate the performance of the neural network models based on both sigmoid function (SF) and radial base function (RBF). To confirm the validity of these systems, fundamental experiments were carried out. The arc was directly observed and recorded as image data using a high-speed camera. The output data from the neural network were compared with the measured data, which were obtained from every captured image. It was found that the neural network model based on the RBF is useful than the SF to estimate the wire extension length in MIG welding because of better responses in the transient state and smaller steady state error.
Electromagnetic scattering from an infinite elliptic metallic cylinder coated by a circular dielectric one

The electromagnetic field is expressed both in terms of circular and elliptical cylindrical wave functions, which are connected with one another by well-known expansion formulas. In the special case of small h=ka/2 (a is the interfocal distance of the elliptic conductor and k the wavenumber of the dielectric coating), exact closed-form expressions of the form S(h)=S(0) (1+g"h/sup 2/+0 (h/sup 4/)) are obtained for the scattered field and the various scattering cross-sections of the problem. <<ETX>>
Diversity of gastrointestinal parasites in sympatric mammals in Moukalaba-Doudou National Park, Gabon

Abstract Background and Aim: Gastrointestinal parasites identified in the wild can negatively affect host fitness, lower performance, and growth. On the other side, sympatric mammals that share habitat and resources may also cross-transmit parasites, which are often zoonotic and can contribute to morbidity and mortality. This study aimed to characterize the diversity of gastrointestinal parasites circulating in mammalian hosts in Moukalaba-Doudou National Park. Materials and Methods: We screened a total of 25 fecal samples collected from nine wild mammalian species, namely, western gorilla (Gorilla gorilla gorilla), chimpanzee (Pan troglodytes), putty-nosed monkey (Cercopithecus nictitans), African forest elephant (Loxodonta cyclotis), African buffalo (Syncerus caffer), blue duiker (Philantomba monticola), bay duiker (Cephalophus dorsalis), and red river hog (Potamochoerus porcus) as well as people working as trackers (Homo sapiens) using direct microscopic observations following a sedimentation technique to concentrate the fecal material. Results: Of the total 25 fecal samples screened, 15 (60%) were positive for parasitic gastrointestinal infection. Based on the morphology of parasite eggs and cysts, we identified a rich diversity of nematodes, protozoans, trematodes, and cestodes, including unidentified strongyles (73%), Oesophagostomum spp. (53%), Ancylostoma spp. (27%), Trichuris spp. (13%), Ascaris spp. (13%), Mammomonogamus spp. (13%), Strongyloides spp. (47%), Balantidium coli (20%), Entamoeba coli (20%), Endolimax nana (6%), Fasciola hepatica (6%), Paramphistomum spp. (13%), and Taenia spp. (6%). Conclusion: All parasites were found at least once in one of the hosts, and most were potentially zoonotic and responsible for several diseases of public health concern. Because of the small sample size, our findings should not be considered conclusive. Nevertheless, they highlight the diversity of gastrointestinal parasites in this area.

Magnet-Only Loudspeaker Magnetic Circuits: A Solution for Significantly Lower Current Distortion

This paper presents a study case which leads to a signiﬁcant decrease of current distortion caused by the magnetic circuit of the loudspeaker: the solution consists in removing all of the nonlinear soft-iron pieces that are used in traditional loudspeaker motors. Thus, in the loudspeaker motors we study, the static magnetic ﬁeld is only created thanks to a combination of permanent magnets. This combination leads to the realization of the so-called magnet-only loudspeakers. Two loudspeakers are compared in the study: the ﬁrst sample is a mass-produced 6.5 inch loudspeaker. The second sample is built replacing the magnetic circuit of the ﬁrst loudspeaker by the magnet-only structure. Thus, the moving part, including the voice-coil, the diaphragm and the suspensions, is kept identical for both samples, leading to a comparison of both loudspeakers only based on their motor. The loudspeaker with the magnet-only motor shows signiﬁcantly lower current distortion than the original loudspeaker. A possible explanation of such a decrease of distortion is given, based on results of a set of measurements with blocked voice-coil.

Running head: PERSISTENCE OF SPIRITUAL EXPERIENCE IN ITALY

This study draws on theories and methods developed within the psychology of religion to examine from a fresh perspective a problem established within the sociology of religion, the ‘oddity of the Italian situation’. The study employs the notion of openness to mystical experience as an indicator of the level of spiritual awareness among a sample of 1,155 Italians ranging in age from 14 to 80 years. The data demonstrated that, while levels of openness to mystical experience remain quite high among non-churchgoing Italians, these levels are significantly associated with sex, age, religious attendance, and personal prayer. Moreover, the differences between attenders and non-attenders are sensitive to the ways in which aspects of mystical experience are expressed. This dialogue between the psychology of religion and the sociology of religion generates fresh insight into the religious and spiritual landscape of Italy today.
Review on EEG-Based Authentication Technology

With the rapid development of brain-computer interface technology, as a new biometric feature, EEG signal has been widely concerned in recent years. The safety of brain-computer interface and the long-term insecurity of biometric authentication have a new solution. This review analyzes the biometrics of EEG signals, and the latest research is involved in the authentication process. This review mainly introduced the method of EEG-based authentication and systematically introduced EEG-based biometric cryptosystems for authentication for the first time. In cryptography, the key is the core basis of authentication in the cryptographic system, and cryptographic technology can effectively improve the security of biometric authentication and protect biometrics. The revocability of EEG-based biometric cryptosystems is an advantage that traditional biometric authentication does not have. Finally, the existing problems and future development directions of identity authentication technology based on EEG signals are proposed, providing a reference for the related studies.
The Effect of Instructional Leadership and Creative Teaching on Student Actualization: Student Satisfaction as a Mediator Variable

This research was carried out to determine the effect of instructional leadership and creative teaching as the main aspects in maximizing student input and potential, in order to achieve learning satisfaction and self-actualization for the educational success of students. The research examines the effect of principal instructional leadership and teaching creativity on self-actualization and its impact on student satisfaction. Across sectional study was used to determine the relationship between exogenous and endogenous variables. Respondents were 307 students on Madrasah Aliyah and Al-Kamal Kebumen Islamic Vocational High Schools, Indonesia. Data was collected using a questionnaire consisting of 4 indicators representing each variable. The research data was analyzed using structural equation modeling (SEM) with the AMOS application. Out of 5 proposed hypotheses, 1 was rejected because of not fulfilling the Critical Ratio (CR) value > 1.96 and the p-value <0.05 criteria. The results showed that this model fulfilled the Goodness of Fit requirements in SEM analysis. It was evident that principal's instructional leadership and creative teaching affects student learning satisfaction. The results also showed that the principal's instructional leadership affects student self-actualization, while creative teaching has no direct effect unless it is mediated by learning satisfaction.
Characterization of corrugated waveguides by modal analysis

A general formulation for the characterization of corrugated waveguides is presented. The formulation is based on modal expansion in the different smooth-walled waveguides which constitute the corrugated structure and on the use of mode matching at discontinuities. The use of an admittance matrix formulation and a suitable root-finding algorithm leads to a rigorous and efficient technique. Dispersion curves are presented for corrugated waveguides of circular and rectangular cross-sections. Complex modes are obtained for deep corrugations. The effect of the finite thickness and width of teeth and slots on the dispersion behavior is shown. >
Semi-Refined Carrageenan Attenuates Lipopolysaccharide-Induced Reactive Oxygen Species Production in Peripheral Blood Mononuclear Cells and Cell Membrane Alterations in Leukocytes

Aim: To assess the effects of semi-refined carrageenan (E407a) on lipopolysaccharide (LPS)-induced reactive oxygen species (ROS) generation in peripheral blood mononuclear cells (PBMCs) and LPS-mediated cell membrane alterations in leukocytes. Methods: Blood samples collected from 8 intact rats were incubated with E407a (10 mg/ml), E407a (50 mg/ml), LPS (1 µg/ml), E407a (10 mg/ml) + LPS (1 µg/ml), E407a (50 mg/ml) + LPS (1 µg/ml) and without those compounds (controls) for 2 h in RPMI 1640 medium enriched with 5% fetal bovine serum. ROS generation in PBMCs obtained from the incubated samples was estimated by flow cytometry using 2',7'-dichlorodihydrofluorescein diacetate (H2DCFDA) staining. The impact of E407a, LPS and their mixture on leukocyte cell membranes was evaluated spectrofluorimetrically using the fluorescent probe 2-(2¢-hydroxy-phenyl)-5-phenyl-1,3-oxazole. Results: Expectedly, incubation with LPS induced ROS generation in PBMCs and decreased the lipid order of cell membranes in leukocytes. E407a alone was found to alter neither ROS production in PBMCs, nor membrane lipid order in leukocytes. Semi-refined carrageenan partially reduced LPS-mediated ROS overproduction in PBMCs and cell membrane alterations in leukocytes. Conclusion: E407a attenuates LPS-induced alterations of redox homeostasis in rat PBMCs and LPS-mediated modifications of cell membrane lipid order in leukocytes.
Criteria for self loosening of fasteners under vibration

A UNIQUE TEST method and apparatus now make it possible to reproduce conditions of vibration that are not only certain to loosen bolted joints but which also closely simulate actual conditions. It can be shown that properly preloaded fasteners loosen as a result of rotation as soon as relative motion occurs between the mating threads and between the bearing surfaces of the fastener and the clamped material.
Market Reaction to Dividend Announcements During Pandemic: An Event Study

This study analyses the difference in stock market reactions to dividend announcement during the pandemic. The thirty constituent stocks of Sensex, the index of Bombay Stock Exchange (BSE), is used for analysis. This allows cross-industry comparison of the market reaction. The study examines stock market reactions covering 44 days around the dividend announcement dates. The primary objective of this study is to understand whether the price adjustment linked to the dividend announcement news during the pandemic was different from the earlier years. This empirical study employs the conventional event study methodology using abnormal returns (ARs) to examine the stock market reaction to dividend announcement. The market reaction to dividend announcement was increasingly positive during the pandemic, compared to previous years. The statistical pooled t-tests showed there was a significant relationship between the pandemic and ARs. The findings also indicate that the difference in the market reaction to dividend announcement was more prominent in services stocks than that in manufacturing. Further, the results also verify the weak-form of efficiency of Indian stock exchange.
Mechanical properties of high-volume fly ash self-compacting concrete mixtures

Self-compacting concrete (SCC), a recent addition to the concrete scenario, is gaining popularity worldwide owing to the ease of its placement without any need for compaction. This paper describes the results of an investigation aimed at producing and evaluating SCC mixtures made with high volumes of class F fly ash. Eight fly ash SCC mixtures of various strength grades (20–100 MPa) were designed at the desired fly ash percentages of 0, 10, 30, 50, 70 and 85%, and were compared with five different mixtures of normal vibrated concrete mixtures (20–100 MPa). Tests were carried out on all mixtures to obtain the properties of fresh concretes in terms of viscosity and stability. The mechanical properties of hardened concretes such as compressive strength, splitting tensile strength and elastic modulus were also determined. The different amounts of paste caused differences in the properties of the two types of concrete. Test results indicated that the use of high volumes of class F fly ash in SCC mixtures decre.
