Rear emitter n-type passivated emitter, rear totally diffused silicon solar cell Structure

In a rear emitter n-type passivated emitter, rear totally diffused cell design, the boron diffused emitters are placed at the rear surface of n-type silicon substrates. This has significantly improved the cell efficiency up to 22.7%. A 170μm thin float zone substrate and a 1. 5Ωcm modest substrate resistivity helped these cells to achieve highly efficient carrier transportation to the rear emitter. These 22cm2 large cells are scribed off from the silicon wafer, representing efficiencies for applicable devices. These rear emitter cells also demonstrated stable performances both under one-sun illumination and after a few months storage in nitrogen.
An ant system for the maximum independent set problem

Early applications of Ant Colony Optimization (ACO) have been mainly concerned with solving ordering problems (e.g., the Traveling Salesperson Problem). More recently, promising results were obtained for solving the Multiple Knapsack Problem by introducing a modification of the standard Ant System algorithm. In this paper we extend our study on the applicability of the ACO approach to subset problems. The computational study involves its applicability for solving the Maximum Independent Set Problem (MISP). The set of instances tested were either randomly generated by specific methods or taken from the so-called DIMACS benchmark graphs. The reported results which are comparable with different state-of-the-art algorithms show the potential of the ACO approach for solving the MISP.
High-resolution measurement of the free spectral range of an etalon

High-resolution measurement of the free spectral range (FSR) for an etalon is becoming more important as greater amounts of information are multiplexed through a single fiber. A method to test the FSR of etalons or etalon based optical components used at telecommunication frequencies is discussed. Slope at a specific point of the etalon response curve is utilized as a means measurement of FSR. The theory that describes how slope, varying as a function of differing etalon signal peaks, can be utilized for the measurement of FSR is developed. This technique has been shown to measure FSR with a resolution of approximately one part in 2000.
Hamiltonian structure of three-dimensional gravity in Vielbein formalism

Considering Chern-Simons like gravity theories in three dimensions as first order systems, we analyze the Hamiltonian structure of three theories Topological massive gravity, New massive gravity, and Zwei-Dreibein Gravity.We show that these systems demonstrate a new feature of the constrained systems in which a new kind of constraints emerge due to factorization of determinant of the matrix of Poisson brackets of constraints. We find the desired number of degrees of freedom as well as the generating functional of local Lorentz transformations and diffeomorphism through canonical structure of the system. We also compare the Hamiltonian structure of linearized version of the considered models with the original ones.
Molecular dynamics simulation of threshold displacement energy and primary damage state in Niobium

In this work, a many-body potential of Nb for radiation damage simulation was developed based on EAM, and most of the point defects of Nb can be predicted properly by this potential. By using the constructed potential, the direction-specific threshold displacement energies (TDE) and displacement cascades up to 20 keV of Nb were performed through molecular dynamics simulations. The calculated results of TDE are in good agreement with previous work for V, Mo and experimental measurements. Lowest TDE was found in direction, and local minas of TDE were found in three low-index directions, which has relation: Ed[100]<Ed[111]<Ed[110]. The evolution of displacement cascades, number of the created point defects, the cascade efficiency the clustering of point defects, and temperature role of these parameters at different PKA energies were systematic investigated. It is found that the cascade efficiency is low and it is can be fitted by a power function as many published work did. The fraction of clustered point defects obtained in this work is low, and only some small clusters were formed at the end of thermal spike. As the temperature increases, the productions of point defects and cascade efficiency were somewhat decreases, however, the fraction of clustered point defects decreases more obvious.
Lagrangian accelerations in geostrophic turbulence

A distinctive property of Lagrangian accelerations in geostrophic turbulence is that they are governed by the large and intermediate scales of the flow, both in time and space, so that the inertial part of the dynamics plays a much larger role than in three-dimensional turbulence where viscous effects are stronger. For the case of geostrophic turbulence on a β-plane, three terms contribute to the Lagrangian accelerations: the ageostrophic pressure gradient which often is the largest term, a meridional acceleration due to the β-effect, and an acceleration due to horizontally divergent ageostrophic motions. Both their spectral characteristics and patterns in physical space are studied in this paper. In particular the total accelerations field has an inertial spectrum slope which is identical to the geostrophic velocity field inertial slope. The accelerations gradient tensor is shown to govern the topology of quasi-geostrophic stirring and transport properties. Its positive eigenvalues locate accurately the position of extrema of potential vorticity gradients. The three-dimensional distribution of tracer gradients is such that the vertical distribution is entirely constrained by the horizontal one, while the reverse is not true. We make explicit analytically their dependence on the three-dimensional accelerations gradient.

A full-color Head Mounted Display (HMD) with both wide field of view and high resolution is very useful for aircraft flight simulation and training. This paper will describe the design evolution of the SIM EYETM from its inception as a monochrome, flight-worthy helmet-mounted display, through its changes to the current a wide field of view, full color, high-resolution HMD.
Technique for high‐pressure electrical conductivity measurement in diamond anvil cells at cryogenic temperatures

A technique is described for making four‐probe electrical conductivity measurements on bulk samples in a diamond anvil cell. The technique has been successfully applied up to 48 GPa and at temperatures below 4.2 K to measure the superconducting transition temperatures (Tc, of Pb, GaP, and Si. A method for analyzing the resistance versus temperature curve in the vicinity of the superconducting transition is also described. This method is applied to determine the pressure dependence of Tc in Si in the region where Tc varies rapidly with pressure.
Comprehensive study of B ̄0 →K0(K̄ 0 )K∓π ± decays in the factorization approach

Using the factorization approach, we investigate the $\overline B^0 \to \overline K^0K^+\pi^-$ and $\overline B^0 \to K^0K^-\pi^+$ decays individually including the resonant and nonresonant contributions. Under the flavor SU(3) symmetry, we obtain the total branching fraction $BR [\overline B^0 \to (\overline K^0K^+\pi^-+K^0K^-\pi^+)]=(7.17^{+0.50+1.97+0.08}_{-0.53-1.42-0.07})\times 10^{-6}$, which is in agreement with the recent measurements of BaBar and LHCb within errors. For the decay $\overline B^0 \to \overline K^0K^+\pi^-$, the nonresonant background and $a_0^+(1450)$ pole in the current-induced process provide large contribution, the latter of which has not been included in previous studies. On the contrary,the decay $\overline B^0 \to K^0K^-\pi^+$ is dominated by the nonresonant background and the offshell $\rho^-$ pole. When the flavor SU(3) symmetry breaking and the final-state rescattering are considered under two different scenarios, the results can also accommodate the experimental data with large uncertainties. Moreover, the direct $CP$ asymmetry of $\overline B^0 \to \overline K^0K^+\pi^-$ is found to be sensitive to the matrix element of scalar density. These predictions could be further tested in the LHCb experiment or Super-b factory in future.

MEDICAL IMAGE COMPRESSION TECHNIQUE FOR TELEMEDICINE APPLICATIONS

In the Internet of medical things (IoMT) and big data era, medical image compression is crucial in today ’ s world. Importantly, compression of large sized medical images is required for everyday tasks, including, storage space utilization and transmission bandwidth of healthcare systems and internet transmissions. However, in this paper, Modified Run Length Encoding (MRLE) is applied as a lossless compression and fast technique to compress medical images. RLE is applied to further increase the compression factor. The goal of using RLE is to enhance the compression factor without adding any distortion to the resultant decompressed image. Since, in healthcare systems and medicine applications, it is necessary to obtain high quality of the decompressed image. Moreover, MRLE is used to enhance the original RLE algorithm. The Block-Block scanning technique will be applied. Thus, this technique produces high efficiency compared with previous RLE techniques. The medical image is divided into equivalent blocks, where, the pixels inside each block are either scanned vertically or horizontally and all blocks together are also scanned vertically or horizontally. In the produced vector, the similar run of the same pixels' value will merge to reduce the size of the output vector. Importantly, the results of the proposed algorithm are shown to be comparable in quality and performance with other existing medical image compression methods.
The Effect of Helicobacter pylori Infection on Overweight: A Systematic Review and Meta-Analysis

Background: The association between Helicobacter pylori infection and overweight, as one of the most common health issues, remains controversial. In this study, we systematically reviewed the effect of H. pylori infection and overweight to get a reliable answer. Methods: We used the Preferred Reporting Items for the Systematic Review and Meta-Analysis statement. We searched the association between H. pylori and overweight infection in international databases including Medline, Web of knowledge and Scopus, without any limitations of language, publication type, and publication status in search step of this systematic review from 2000 to 2020. We surveyed the title, abstract and full text of each research studies, and we used Newcastle-Ottawa quality for assessing the quality of each paper. A random effects model was used to calculate the pooled odd ratio with 95% confidence intervals. Results: Fifteen papers were eligible for this review. The selected studies reported different Odd Ratio between overweight and H. pylori infection but Odds Ratio (95% confidence interval) in our systematic and meta-analysis study was estimated at 1.42 (95% CI; 1.12, 1.81) and it was statistically significant (P: 0.003). Conclusion: H. pylori infection is significantly associated with overweight, therefore, the eradication of H. pylori infection is suggested because this infectious might be resulted in overweight.
The Association Between Affective Temperament Traits and Dopamine Genes in Obese Population

Studies indicate the heritable nature of affective temperament, which shows personality traits predisposing to the development of mental disorders. Dopaminergic gene polymorphisms such as DRD4, COMTVal158Met, and DAT1 have been linked to affective disorders in obesity. Due to possible correlation between the aforementioned polymorphisms and the affective temperament, the aim of our research was to investigate this connection in an obese population. The study enrolled 245 obese patients (178 females; 67 males). The affective temperament was assessed using the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego autoquestionnaire (TEMPS-A). Genetic polymorphisms of DAT1, COMTVal158Met and DRD4 were collected from peripheral blood sample and determined using a polymerase chain reaction (PCR). Only in COMT polymorphisms, the cyclothymic and irritable dimensions were significantly associated with Met/Val carriers (p = 0.04; p = 0.01). Another interesting finding was the correlation between the affective temperament and age in men and women. We assume that dopamine transmission in heterozygotes of COMT may determine the role of the affective temperament in obese persons. Dopaminergic transmission modulated by COMT may be responsible for a greater temperament expression in obese individuals. To our knowledge, this is the first study describing the role of affective temperament in the obese population, but more research is needed in this regard.
Supersymmetric manipulation of quasienergy states. Application to the Berry phase

Time-dependent supersymmetry allows one to delete quasienergy levels for time-periodic Hamiltonians and to create new ones. We illustrate this by examining an exactly solvable model related to the simple harmonic oscillator with a time-varying frequency. For an interesting nonharmonic example we present the change of the Berry phase due to a supersymmetry transformation.
Composite likelihood estimation in multivariate data analysis

The authors propose two composite likelihood estimation procedures for multivariate models with regression/univariate and dependence parameters. One is a two‐stage method based on both univariate and bivariate margins. The other estimates all the parameters simultaneously based on bivariate margins. For some special cases, the authors compare their asymptotic efficiencies with the maximum likelihood method. The performance of the two methods is reasonable, except that the first procedure is inefficient for the regression parameters under strong dependence. The second approach is generally better for the regression parameters, but less efficient for the dependence parameters under weak dependence.
Global patterns of the quasi-biennial oscillation in total ozone

Abstract Nine years of total ozone measurements from the Total Ozone Mapping Spectrometer (TOMS) on Nimbus 7 are used to study the global structure of the quasi-biennial oscillation (QBO) in total ozone. Interannual variability of total ozone near the equator (10°S to 10°N) is dominated by the QBO. The equatorial ozone anomalies are independent of season and are well correlated (r > 0.8) with the equatorial zonal wind. In both hemispheres midlatitude anomalies are two to three times larger in winter than in summer. Global patterns of the ozone QBO are identified by computing lagged correlations between the zonal-mean equatorial ozone and ozone elsewhere on the globe. Correlations between equatorial and extratropical ozone are weak during the summer season (r ∼ 0) and large and negative during the winter (r < − 0.8 in the Southern Hemisphere and r − 0.6 in the Northern Hemisphere). There are nodes or phase shifts in the correlation patterns at ±10° latitude, at 60°S, and at 50°N. Large negative correlation.
Prevalence and severity of discharge medication discrepancies resolved by pharmacists at a veterans affairs teaching hospital

Although reassuring outcome data exist, not all pharmacist discharge efforts have been effective. This may be explained by heterogenous medication reconciliation definitions and processes. At a Veterans Affairs Teaching Hospital, Clinical Pharmacy Specialists (CPS) review the discharge medication reconciliation as part of a multidisciplinary process. The objective of this study is to describe CPS' role in resolving discharge medication reconciliation discrepancies and to evaluate potential patient harm avoided through pharmacist intervention.
The Age of the Sculptor Dwarf Spheroidal Galaxy from Imaging with WFPC2

From images taken with the Hubble Space Telescope's WFPC2, we have obtained photometry of a field in the Sculptor dwarf spheroidal galaxy to 3 mag below the main‐sequence turnoff. We determine an age equal to that of the earliest globular clusters for the bulk of the stars in our field of view. We attempt to constrain the star formation history of the Sculptor dwarf by examining the main‐sequence luminosity function. The presence of a half‐dozen blue straggler candidates blueward of the turnoff points to a possibly complex star formation history. However, the contribution of any intermediate‐age population is difficult to measure conclusively, because of the uncertain origin of blue stragglers and the sparseness of the photometric sample.
Examining the effects of electronic service quality on online banking customer satisfaction: Evidence from Zambia

Abstract While several studies examine the influence of service quality on customer satisfaction in physical retail banking offices, there is a shortage of studies on service quality in the digital space of banking. Further, many developing country contexts such as Zambia are under-researched, limiting the generalisability of prior research conclusions. Hence, the purpose of this research is to examine electronic service quality in online retail banking and its influence on customer satisfaction during COVID-19 pandemic restrictions in the under-researched context of Zambia. Based on a quantitative correlational design, primary sample data were collected using a structured questionnaire from 314 bank customers from two of Zambia’s largest cities, Lusaka and Kitwe. The data were analysed using correlation and multiple regression models. The findings indicate that the E-SERVQUAL model is applicable in the Zambian context and that security, website attribute, privacy, responsiveness, efficiency, fulfilment and reliability are indeed relevant to electronic service quality and they affect customer satisfaction; the multiple coefficients of determination (51.1%) and correlation (71.5%) indicate a large effect size. This extends the E-SERVQUAL model into the under-researched developing country context of online banking in Zambia during the COVID-19 restrictions. The implications to policy and practice are that improving security, website attributes, privacy, efficiency, responsiveness, fulfilment and reliability would result in higher customer satisfaction and usage of the online facilities. Since the study was limited to two, albeit the biggest, cities of Zambia, increasing the number of cities and countries sampled would improve generalisability.
A System-Level Methodology for the Design of Reliable Low-Power Wireless Sensor Networks

Innovative Internet of Things (IoT) applications with strict performance and energy consumption requirements and where the agile collection of data is paramount are arising. Wireless sensor networks (WSNs) represent a promising solution as they can be easily deployed to sense, process, and forward data. The large number of Sensor Nodes (SNs) composing a WSN are expected to be autonomous, with a node’s lifetime dictated by the battery’s size. As the form factor of the SN is critical in various use cases, minimizing energy consumption while ensuring availability becomes a priority. Moreover, energy harvesting techniques are increasingly considered as a viable solution for building an entirely green SN and prolonging its lifetime. In the process of building a SN and in the absence of a clear and well-rounded methodology, the designer can easily make unfounded and suboptimal decisions about the right hardware components, their configuration, and reliable data communication techniques, such as automatic repeat request (ARQ) and forward error correction (FEC). In this paper, a methodology to design, configure, and deploy a reliable ultra-low power WSNs is proposed. A comprehensive energy model and a realistic path-loss (PL) model of the sensor node are also established. Through estimations and field measurements it is proven that, following the proposed methodology, the designer can thoroughly explore the design space and the make most favorable decisions when choosing commercial off-the-shelf (COTS) components, configuring the node, and deploying a reliable and energy-efficient WSN.
