Systematic Literature Review on Test Case Selection and Prioritization: A Tertiary Study

Software testing is undertaken to ensure that the software meets the expected requirements. The intention is to find bugs, errors, or defects in the developed software so that they can be fixed before deployment. Testing of the software is needed even after it is deployed. Regression testing is an inevitable part of software development, and must be accomplished in the maintenance phase of software development to ensure software reliability. The existing literature presents a large amount of relevant knowledge about the types of techniques and approaches used in regression test case selection and prioritization (TCS&P), comparisons of techniques used in TCS&P, and the data used. Numerous secondary studies (surveys or reviews) have been conducted in the area of TCS&P. This study aimed to provide a comprehensive examination of the analysis of the enhancements in TCS&P using a thorough systematic literature review (SLR) of the existing secondary studies. This SLR provides: (1) a collection of all the valuable secondary studies (and their qualitative analysis); (2) a thorough analysis of the publications and the trends of the secondary studies; (3) a classification of the various approaches used in the secondary studies; (4) insight into the specializations and range of years covered in the secondary texts; (5) a comprehensive list of statistical tests and tools used in the area; (6) insight into the quality of the secondary studies based on the seven selected Research Paper Quality parameters; (7) the common problems and challenges encountered by researchers; (8) common gaps and limitations of the studies; and (9) the probable prospects for research in the field of TCS&P.
Analysis of Local and Centralized Control of PV Inverters for Voltage Support in Distribution Feeders

Higher photovoltaic penetration on distribution system brings operational challenges including overvoltage issues. With smart inverters, efficient voltage control can be achieved through adjusting active/reactive powers of inverters. However, reactive power may not be as effective as active power in regulating voltage due to high R/X ratio of distribution networks. Thus, active power curtailment (APC) techniques in coordination with reactive power control are required in distribution networks. In this study, we aim to evaluate the performances of a sensitivity based method and an optimal power flow (OPF) based centralized method of reactive power control (in coordination with APC) from inverters in managing voltage profile on distribution networks. We performed simulations on a 730-node MV/LV system upto 100% PV penetration. Based on the case studies using different penetration levels of PVs, we observed that: a) sensitivity based method is not always able to solve overvoltage issues and energy curtailments are high, and b) OPF-based method can ensure that voltage remains within the operational bound with significantly less energy curtailment.
A GUI tool for beta function measurement using MATLAB

The beta function measurement is used to detect the shift in the betatron tune as the strength of an individual quadrupole magnet is varied. A GUI (graphic user interface) tool for the beta function measurement is developed using the MATLAB program language in the Linux environment, which facilitates the commissioning of the Shanghai Synchrotron Radiation Facility (SSRF) storage ring. In this paper, we describe the design of the application and give some measuring results and discussions about the definition of the measurement. The program has been optimized to solve some restrictions of the AT tracking code. After the correction with LOCO (linear optics from closed orbits), the horizontal and the vertical root mean square values (rms values) can be reduced to 0.12 and 0.10.
The resource recovery level decision for end-of-life products

Resource recovery from end-of-life (EOL) products is becoming increasingly engaged in by companies as a response to customer, consumer, government and social pressures, the electronics industry cites competitor pressures as being the main driver of EOL product take-back and recovery. Recovery can occur at three levels; i.e. product, part and material. Each of these options has economic and environmental advantages and disadvantages depending on the product type and a host of other influencing factors. The work described in this paper supports the decision as to the most favourable route from a cost and value perspective, a software model that provides such support is also described.
A Method for Making Cross-Comparable Estimates of the Benefits of Decision Support Technologies for Air Traffic Management

We present a general method for making cross comparable estimates of the benefits of NASA-developed decision support technologies for air traffic management and we apply a specific implementation, or "instantiation" of the method to estimate benefits of three decision support tools, Active Final Approach Spacing Tool (AFAST), Expedite Departure Path (EDP), and Conflict Probe and Trial Planning Tool (CPTP). The report also reviews data about the present operation of the national airspace system (NAS) to identify opportunities for DST''s to reduce delays and inefficiencies.
HIGH GAIN SUBSTRATE INTEGRATED WAVEGUIDE FED YAGI-UDA ANTENNA ARRAY ON SILICON SUBSTRATE FOR MULTIBAND APPLICATIONS

This paper proposes a Yagi-Uda antenna array realized on a Silicon substrate and supported by a substrate integrated waveguide for multi-band operation in the K and Ka bands. The structure of the dipole and the first director of the Yagi-Uda antenna were modified and tuned for multi-band response, making it completely novel in comparison to the existing Yagi-Uda structures supporting multi-band operation. As the feed, a substrate integrated waveguide was designed to assist with multi-band operation and to overcome the challenges presented by the Silicon substrate. An array is implemented to improve the gain. The antenna array’s prototype was constructed and tested to back up the claims. The proposed array operates at frequencies of 23.7, 26.3, 27.5–28.3, and 29.4GHz. The array exhibits good end-fire radiation patterns for the resonant frequencies, with a peak gain of 19.65 dBi and an efficiency of 89.8% at 23.7GHz. This is the first report of an antenna fed by a substrate integrated waveguide and realized on Silicon with a high gain and applications in the K and Ka bands.
Pozzolanic properties of a variety of European clay bricks

Clay bricks from Britain, Denmark, Lithuania and Poland have been ground up, investigated and analysed for particle size distribution, chemical composition, mineralogical content and strength. The ground brick types have also been used to partially replace cement in mortar. Chemical tests for pozzolanic activity confirm that all the brick types investigated have good pozzolanic activity and this is supported by strength development data of the mortar bars. A significant variation in relative strength between mortars made with the different ground brick types and the reasons for this variation are discussed. The work reported involves potential utilization of waste clay bricks in the production of durable mortar and concrete. Cetteetude porte sur proprietes pouzzolaniques de briques d'argile pilees provenant de Grande Bretagne, du Danemark, de Lituanie et de Pologne et plus particulierement leur granulometrie, leur composition chimique, leur teneur en mineraux et leur resistance.

Virtual Walking With Omnidirectional Movies and Foot Vibrations: Scene-Congruent Vibrations Enhance Walking-Related Sensations and Ground Material Perceptions

Walking is a human need. Even when physical disabilities or social situations, such as the COVID-19 pandemic, prevent people from walking, virtual reality can provide an opportunity for virtual walking or travel. In this study, a virtual walking system was developed in which users view omnidirectional movies while receiving scene-congruent vibrations to their left and right forefeet and heels. The timings of foot vibrations were generated by estimating the camera motion trajectory with visual simultaneous localization and mapping (visual SLAM) applied to four omnidirectional movies. Congruent vibration patterns were prepared for four ground scenes. Modulation of walking-related sensations and ground material perceptions by congruent and incongruent vibrations was verified using psychological measurements. The results showed that rhythmic foot vibration improved the sensations of self-motion, walking, leg action, and telepresence irrespective of scene–vibration congruency. Moreover, congruent vibrations were better than incongruent vibrations for walking-related sensations and telepresence in indoor corridors and snowy ground scenes. The perception of ground materials was enhanced by scene-congruent vibrations, whereas it was confused by scene-incongruent vibrations. These findings suggest that vibration patterns do not necessarily need to match the ground exactly to induce virtual walking sensations; however, scene-congruent or similar vibrations improve virtual walking sensations and ground material perception. By applying our methods, we can convert various public omnidirectional movies into realistic virtual walking experiences.
Influence of preceding North Atlantic Oscillation on the spring precipitation in the middle and lower reaches of the Yangtze River valley

The relationship between the spring precipitation in the middle and lower reaches of the Yangtze River valley and the North Atlantic Oscillation in the preceding winter is investigated based on data diagnosis. Through affecting the dynamics and thermodynamics in near‐surface atmosphere over Eurasia, the North Atlantic Oscillation in January can exert significant influence on the Eurasian snow cover to form a dipole pattern of snow anomalies. The dipole pattern of snow anomalies stimulates the Rossby wave train in the middle and high latitudes of the Northern Hemisphere in the following spring. Two activity centres associated with the wave train, one in the middle latitudes of Northwest Pacific with an anomalous anticyclone circulation and another in Mongolia with an anomalous cyclone circulation, bring the water vapour from the south and converge over the middle and lower reaches of the Yangtze River, resulting in the excessive precipitation over there. The results indicate that the North Atlantic Oscillation in January can act as a precursor signal for predicting the spring rainfall anomalies in the middle and lower reaches of the Yangtze River.
The Photometric and Spectroscopic Properties of Remnant and Restarted Radio Galaxies in the Lockman Hole Field

Radio galaxies are known to undergo phases of activity, where the stage after the jets have switched off is referred to as the remnant phase. This state can be followed by a restarted phase when the activity reignites. Remnant and restarted radio sources are important for testing models of the evolution of radio active galactic nuclei (AGN) and for understanding the impact the recurrent jet activity has on their host galaxies. Although we now have statistical samples of radio sources in various stages of their life cycle, how this intermittent radio activity is reflected in the optical properties in this sample has not yet been addressed, and is overall a much less studied aspect in the literature. In this work, we use the Wide-field Infrared Survey Explorer and the Sloan Digital Sky Survey (SDSS) photometry, and SDSS spectra to study these properties in a sample of the remnant, candidate restarted, and active radio galaxies selected using the LOw Frequency ARray at 150 MHz in the Lockman Hole extragalactic field. Within the range of radio luminosities and stellar masses studied in this work, we find no difference between the properties of the host galaxy and of the optical emission lines for objects in different phases of their radio life cycle. The vast majority of our radio sources (either remnant, candidate restarted, or comparison sample) are associated with radiatively inefficient optical AGN and red galaxies dominated by old stellar populations. Thus, the radio and emission-line AGN activity appears to be independent and regulated by different mechanisms. This suggests that, at least for the radio luminosities of our sample, the life cycle of the radio may depend on intrinsic reasons, such as the stability of the accretion disc, more than variation in the accretion rate and fuelling of the central black hole.
A new efficient method of analysis for inhomogeneous media shields and filters

In this paper, we discuss the shielding characteristics of an inhomogeneous shield for oblique incidence. The inhomogeneity considered can be modeled via a continuous spatial variation of the permittivity along the power-flow direction and can be taken into account in the mathematical model involving the transmission line equivalent-circuit representation in terms of a longitudinal-line impedance and a transverse-line admittance varying along the same direction. In order to design a filter or a matching line layout with such a material, new analytical expressions of the reflection coefficient and of the shielding factor for nonuniform dielectric slabs are found. Some numerical examples are also presented for both the TE and TM polarization cases.
Development and testing of a 20-kW grid interactive photovoltaic power conditioning system in Western Australia

A prototype current-controlled power conditioning system has been developed and tested on a weak rural feeder line at Kalbarri, about 600 km northwest of Perth in Western Australia. This system sources 20 kW of power from a photovoltaic array with maximum power point tracking control. In addition, it provides voltage support for the power grid at Kalbarri by varying its reactive power in response to the measured voltage at the point of connection. This paper describes the development and testing of the power conditioning system.
Estimation of runoff depths on paved areas

A study was carried out to produce design guidance on maximum water depths and runoff rates from impervious pavements. The guidance improves on current design practice by taking into account parameters such as the pavement surface characteristics and geometry, critical storm duration and geographical location of the catchment. This paper describes the site monitoring programme for data collection that led to the development of roughness equations for various types of pavement surface. The field measurements were also used to validate a rainfall-runoff numerical model based on kinematic wave theory that was also produced as part of this study and which allowed the development of general design guidance.
Analysis of Tizen Security Model and Ways of Bypassing It on Smart TV Platform

The smart TV market is growing at an ever faster pace every year. Smart TVs are equipped with many advanced functions, allow users to search, chat, browse, share, update, and download different content. That is one of the reason why smart TVs became a target for the hacker community. In this article, we decided to test security of Tizen operating system, which is one of the most popular smart TV operating systems. Tizen is used on many different devices including smartphones, notebooks, wearables, infotainment systems, and smart TVs. By now, there are articles which present security mechanisms of Tizen OS, and sometimes with a way to bypass them; however, none of them are applicable to the smart TVs. In the article, we focused on developing an algorithm that will allow us to gain root access to the smart TV. The proposed attack scenario uses CVE-2014-1303 and CVE-2015-1805 bugs to bypass or disable security mechanisms in Tizen OS and finally gain root access.
Development of a MIP-Based QCM Sensor for Selective Detection of Penicillins in Aqueous Media

Pharmaceuticals wastes have been recognized as emerging pollutants to the environment. Among those, antibiotics in the aquatic environment are one of the major sources of concern, as chronic, low-dose exposure can lead to antibiotic resistance. Herein, we report on molecularly imprinted polymers (MIP) to recognize penicillin V potassium salt (PenV-K), penicillin G potassium salt (PenG-K), and amoxicillin sodium salt (Amo-Na), which belong to the most widespread group of antibiotics worldwide. Characterization and optimization led to two MIPs comprising methacrylic acid as the monomer and roughly 55% ethylene glycol dimethacrylate as the crosslinker. The obtained layers led to sensitive, selective, repeatable, and reusable sensor responses on quartz crystal microbalances (QCM). The LoD for PenV-K, PenG-K, and Amo-Na sensors are 0.25 mM, 0.30 mM, and 0.28 mM, respectively; imprinting factors reach at least around three. Furthermore, the sensors displayed relative selectivity factors of up to 50% among the three penicillins, which is appreciable given their structural similarity.
Norovirus Vaccines: Current Clinical Development and Challenges

Noroviruses are the major viral pathogens causing epidemic and endemic acute gastroenteritis with significant morbidity and mortality. While vaccines against norovirus diseases have been shown to be of high significance, the development of a broadly effective norovirus vaccine remains difficult, owing to the wide genetic and antigenic diversity of noroviruses with multiple co-circulated variants of various genotypes. In addition, the absence of a robust cell culture system, an efficient animal model, and reliable immune markers of norovirus protection for vaccine evaluation further hinders the developmental process. Among the vaccine candidates that are currently under clinical studies, recombinant VP1-based virus-like particles (VLPs) that mimic major antigenic features of noroviruses are the common ones, with proven safety, immunogenicity, and protective efficacy, supporting a high success likelihood of a useful norovirus vaccine. This short article reviews the recent progress in norovirus vaccine development, focusing on those from recent clinical studies, as well as summarizes the barriers that are being encountered in this developmental process and discusses issues of future perspective.
Half-mode substrate integrated plasmonic waveguide for filter and diplexer designs

A half-mode substrate integrated waveguide (HMSIW) combined with spoof surface plasmon polariton (SSPP) structure is proposed to realize bandpass filter (BPF) characteristic and miniaturization, which is termed as the half-mode substrate integrated plasmonic waveguide (HMSIPW). Compared with the conventional HMSIW structure having identical cutoff frequency, this new design of HMSIPW not only supports SSPP modes, but also realizes a transversal size reduction of 19.4% and longitudinal reduction of more than 60%. Then, a diplexer based on two back-to-back placed HMSIPW BPFs is designed, and it has only one row of metallized via holes to further reduce the transversal size. The experimental prototypes of the filters and diplexer have been manufactured, and the measurement results agree well with simulation ones. Due to the size miniaturization and simple structure, the proposed designs will have many potentials in the integrated devices and circuits for wireless communication systems.
CNNM proteins selectively bind to the TRPM7 channel to stimulate divalent cation entry into cells

Magnesium is essential for cellular life, but how it is homeostatically controlled still remains poorly understood. Here, we report that members of CNNM family, which have been controversially implicated in both cellular Mg2+ influx and efflux, selectively bind to the TRPM7 channel to stimulate divalent cation entry into cells. Coexpression of CNNMs with the channel markedly increased uptake of divalent cations, which is prevented by an inactivating mutation to the channel’s pore. Knockout (KO) of TRPM7 in cells or application of the TRPM7 channel inhibitor NS8593 also interfered with CNNM-stimulated divalent cation uptake. Conversely, KO of CNNM3 and CNNM4 in HEK-293 cells significantly reduced TRPM7-mediated divalent cation entry, without affecting TRPM7 protein expression or its cell surface levels. Furthermore, we found that cellular overexpression of phosphatases of regenerating liver (PRLs), known CNNMs binding partners, stimulated TRPM7-dependent divalent cation entry and that CNNMs were required for this activity. Whole-cell electrophysiological recordings demonstrated that deletion of CNNM3 and CNNM4 from HEK-293 cells interfered with heterologously expressed and native TRPM7 channel function. We conclude that CNNMs employ the TRPM7 channel to mediate divalent cation influx and that CNNMs also possess separate TRPM7-independent Mg2+ efflux activities that contribute to CNNMs’ control of cellular Mg2+ homeostasis.
Phase-controlled DC-AC converter with high-frequency switching

An analysis of the phase-controlled DC-AC converter is presented. This converter has a pair of switches in each side of the primary and the secondary of the isolation transformer. The voltage conversion ratio is controlled by the phase difference between the two pairs of switches. The averaged equivalent circuit for low frequency operation is derived. The switching surge during commutation is much reduced by dividing the reactor into two parts. As a result, the transformer is miniaturized by increasing the switching frequency and the reactive energy can be easily recovered to the DC source. This DC-AC converter is especially suitable for small uninterruptible power supply systems. >
Genome-Wide Association Study Candidate Genes on Mammary System-Related Teat-Shape Conformation Traits in Chinese Holstein Cattle

In the dairy industry, mammary system traits are economically important for dairy animals, and it is important to explain their fundamental genetic architecture in Holstein cattle. Good and stable mammary system-related teat traits are essential for producer profitability in animal fitness and in the safety of dairy production. In this study, we conducted a genome-wide association study on three traits—anterior teat position (ATP), posterior teat position (PTP), and front teat length (FTL)—in which the FarmCPU method was used for association analyses. Phenotypic data were collected from 1000 Chinese Holstein cattle, and the GeneSeek Genomic Profiler Bovine 100K single-nucleotide polymorphisms (SNP) chip was used for cattle genotyping data. After the quality control process, 984 individual cattle and 84,406 SNPs remained for GWAS work analysis. Nine SNPs were detected significantly associated with mammary-system-related teat traits after a Bonferroni correction (p < 5.92 × 10−7), and genes within a region of 200 kb upstream or downstream of these SNPs were performed bioinformatics analysis. A total of 36 gene ontology (GO) terms and 3 Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were significantly enriched (p < 0.05), and these terms and pathways are mainly related to metabolic processes, immune response, and cellular and amino acid catabolic processes. Eleven genes including MMS22L, E2F8, CSRP3, CDH11, PEX26, HAL, TAMM41, HIVEP3, SBF2, MYO16 and STXBP6 were selected as candidate genes that might play roles in the teat traits of cows. These results identify SNPs and candidate genes that give helpful biological information for the genetic architecture of these teat traits, thus contributing to the dairy production, health, and genetic selection of Chinese Holstein cattle.
