Lean requirements traceability automation enabled by model-driven engineering
Authors: Escalona María-José , Koch Nora , Garcia-Borgoñon Laura 
Published: January 2022

BackgroundThe benefits of requirements traceability, such as improvements in software product and process quality, early testing, and software maintenance, are widely described in the literature. Requirements traceability is a critical, widely accepted practice. However, very often it is not applied for fear of the additional costs associated with manual efforts or the use of additional tools.MethodsThis article presents a “low-cost” mechanism for automating requirements traceability based on the model-driven paradigm and formalized by a metamodel for the creation and monitoring of traces and an integration process for traceability management. This approach can also be useful for information fusion in industry insofar that it facilitates data traceability.ResultsThis article extends an existing model-driven development methodology to incorporate traceability as part of its development tool. The tool has been used successfully by several companies in real software development projects, helping developers to manage ongoing changes in functional requirements. One of those projects is cited as an example in the paper. The authors’ current work leads them to conclude that a model-driven engineering approach, traditionally used only for the automatic generation of code in a software development process, can also be used to successfully automate and integrate traceability management without additional costs. The systematic evaluation of traceability management in industrial projects constitutes a promising area for future work.

Background
A journal’s impact factor (IF) and total citations are often used as indicators of its publication quality. Furthermore, journals that require authors to abide by reporting guidelines or conduct trial registration generally have a higher quality of reporting. In this study, we sought to explore the potential associations between the enforcement of reporting guidelines or trial registration and a surgical journal’s IF or total citations in order to find new approaches and ideas to improve journal publication quality.

Methods
We examined surgical journals from the 2018 Journal Citation Report’s Expanded Scientific Citation Index to quantify the use of reporting guidelines or study registration. We reviewed the “instructions for authors” from each journal and used multivariable linear regression analysis to determine which guidelines were associated with the journal IF and total citations. The dependent variable was the logarithm base 10 of the IF in 2018 or the logarithm base 10 of total citations in 2018 (the results were presented as geometric means, specifically the ratio of the “endorsed group” results to “not endorsed group” results). The independent variable was one of the requirements (endorsed and not endorsed). Models adjust for the publication region, language, start year, publisher and journal size (only used to adjust total citations).

Results
We included 188 surgical journals in our study. The results of multivariable linear regression analysis showed that journal IF was associated (P < 0.01) with the following requirements: randomized controlled trial (RCT) registration (geometric means ratio (GR) = 1.422, 95% CI [1.197–1.694]), Consolidated Standards of Reporting Trials (CONSORT) statement (1.318, [1.104–1.578]), Preferred Reporting Items for Systematic Reviews Meta-Analyses (PRISMA) statement (1.390, [1.148–1.683]), Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement (1.556, [1.262–1.919]), Standards for Reporting Diagnostic Accuracy (STARD) statement (1.585, [1.216–2.070]), and Meta-analysis of Observational Studies in Epidemiology (MOOSE) statement (2.113, [1.422–3.133]). We found associations between the endorsement of RCT registration (GR = 1.652, 95% CI [1.268–2.153]), CONSORT (1.570, [1.199–2.061]), PRISMA (1.698, [1.271–2.270]), STROBE (2.023, [1.476–2.773]), STARD (2.173, [1.452–3.243]), and MOOSE statements (2.249, [1.219–4.150]) and the number of total citations.

Conclusion
The presence of reporting guidelines and trial registration was associated with higher IF or more total citations in surgical journals. If more surgical journals incorporate these policies into their submission requirements, this may improve publication quality, thus increasing their IF and total citations.

The main objective of this review study was to examine the validity of test results generated by using the Ziehl-Neelsen smear microscopy as the sole diagnostic tool for the monitoring and surveillance of bovine tuberculosis in cattle slaughtered in Eswatini.
Methods: A retrospective analysis of available laboratory data of beef carcass condemnations for a study period from 2014 to 2018 was carried out. Literature was reviewed to find out potential sample preparation and concentration methods to improve the sensitivity of current Z-N smear microscopy.
Results: The limited literature reviewed in this study has briefly highlighted (i) the limitations of using the Z-N direct smear microscopy as a screening and confirmatory laboratory test for bovine tuberculosis suspected carcasses, (ii) that the Z-N smear microscopy method may be inadequate for identifying and differentiating other acid fast bacilli co-existing in a M. bovis infection, (iii) that concentration of lymph node aspirate samples may improve the sensitivity of acid fast bacilli smear microscopy, (iv) that strategic deployment of ancillary laboratory tests, such as the Rapid diagnostic tests (RDT) and the Polymerase chain reaction test (PCR) alongside the Z-N smear microscopy may achieve an adequate level of diagnostic test performance.
Conclusion: In order to strengthen the surveillance and monitoring of bovine tuberculosis in the country, it is necessary to consider techniques for the concentration of bovine tuberculosis suspect lymph node samples, to use Rapid diagnostic test Kits in parallel to the Z-N direct smear microscopy.

AbstractLead‐based halide perovskite crystals are shown to have strongly anharmonic structural dynamics. This behavior is important because it may be the origin of their exceptional photovoltaic properties. The double perovskite, Cs2AgBiBr6, has been recently studied as a lead‐free alternative for optoelectronic applications. However, it does not exhibit the excellent photovoltaic activity of the lead‐based halide perovskites. Therefore, to explore the correlation between the anharmonic structural dynamics and optoelectronic properties in lead‐based halide perovskites, the structural dynamics of Cs2AgBiBr6are investigated and are compared to its lead‐based analog, CsPbBr3. Using temperature‐dependent Raman measurements, it is found that both materials are indeed strongly anharmonic. Nonetheless, the expression of their anharmonic behavior is markedly different. Cs2AgBiBr6has well‐defined normal modes throughout the measured temperature range, while CsPbBr3exhibits a complete breakdown of the normal‐mode picture above 200 K. It is suggested that the breakdown of the normal‐mode picture implies that the average crystal structure may not be a proper starting point to understand the electronic properties of the crystal. In addition to our main findings, an unreported phase of Cs2AgBiBr6is also discovered below ≈37 K.

AbstractThe design, fabrication, and characterization of wafer‐scale, zero‐bias power detectors based on 2D MoS2 field‐effect transistors (FETs) are demonstrated. The MoS2 FETs are fabricated using a wafer‐scale process on 8 μm‐thick polyimide film, which, in principle, serves as a flexible substrate. The performances of two chemical vapor deposition MoS2 sheets, grown with different processes and showing different thicknesses, are analyzed and compared from the single device fabrication and characterization steps to the circuit level. The power‐detector prototypes exploit the nonlinearity of the transistors above the cut‐off frequency of the devices. The proposed detectors are designed employing a transistor model based on measurement results. The fabricated circuits operate in the Ku‐band between 12 and 18 GHz, with a demonstrated voltage responsivity of 45 V W−1 at 18 GHz in the case of monolayer MoS2 and 104 V W−1 at 16 GHz in the case of multilayer MoS2, both achieved without applied DC bias. They are the best‐performing power detectors fabricated on flexible substrate reported to date. The measured dynamic range exceeds 30 dB, outperforming other semiconductor technologies like silicon complementary metal–oxide–semiconductor circuits and GaAs Schottky diodes.

Published: January 2022

AbstractEfficient electrode materials, that combine high power and high energy, are the crucial requisites of sodium‐ion batteries (SIBs), which have unwrapped new possibilities in the areas of grid‐scale energy storage. Hard carbons (HCs) are considered as the leading candidate anode materials for SIBs, however, the primary challenge of slow charge‐transfer kinetics at the low potential region (<0.1 V) remains unresolved till date, and the underlying structure–performance correlation is under debate. Herein, ultrafast sodium storage in the whole‐voltage‐region (0.01–2 V), with the Na+ diffusion coefficient enhanced by 2 orders of magnitude (≈10–7 cm2 s–1) through rationally deploying the physical parameters of HCs using a ZnO‐assisted bulk etching strategy is reported. It is unveiled that the Na+ adsorption energy (Ea) and diffusion barrier (Eb) are in a positive and negative linear relationship with the carbon p‐band center, respectively, and balance of Ea and Eb is critical in enhancing the charge‐storage kinetics. The charge‐storage mechanism in HCs is evidenced through comprehensive in(ex) situ techniques. The as prepared HCs microspheres deliver a record high rate performance of 107 mAh g–1 @ 50 A g–1 and unprecedented electrochemical performance at extremely low temperature (426 mAh g–1 @ −40 °C).

Published: January 2022

AbstractAlthough multiple emissive materials are of great research interest due to their great potential in a variety of applications, it is still challenging to prepare highly luminescent color‐tunable phosphors. Herein, the authors report a series of Pb−Sn alloyed single crystals, (C10NH22)2Pb1−xSnxBr4 (x = 0 to 1), that are equipped with two independent self‐trapped excitons (STEs) emitters. Multicolor luminescent output from blue to red and white light can be obtained by tailoring the composition, excitation wavelength, temperature, or time gating. More importantly, the synergistic effect between PbBr42− and SnBr42− enables (C10NH22)2Pb1−xSnxBr4 to have an extremely high luminescent efficiency up to near unity and remarkably extends stability in ambient air, significantly outperforming the monometallic (C10NH22)2PbBr4 and (C10NH22)2SnBr4. As an encouraging result of the richly endowed emission property and robust stability, (C10NH22)2Pb1−xSnxBr4 is further employed in multifunctional applications including the luminescent radiometric thermometer, white light emitter, and high‐security anti‐counterfeit materials.

Published: January 2022

AbstractAn electrochemical hydroxysulfonylation of α‐CF3 alkenes was accomplished in this work. By using easily available sodium sulfinates as the sulfonylating agents, a series of valuable α‐trifluoromethyl tertiary alcohols were synthesized under mild and environmentally friendly electrolysis conditions in moderate to good yields. The preliminary mechanistic investigation indicates that this difunctional reaction involves a radical process via a sulfonyl radical. Gram‐scale synthesis shows the significant potential application of this protocol.magnified image
A Novel Theoretical Model Development and Simulation of Melt‐Electrospinning Using Kane's and Udwadia–Kalaba Methods
Authors: Wubneh Abiy , Ayranci Cagri , Kim Chun‐IL 
Published: January 2022

AbstractA novel analytical model development and simulation of melt‐electrospinning process is presented. Unconstrained equations of motion for the description of a discretized melt‐electrospun fiber are formulated using Kane's method. The motions of the spinneret and the collector plate are also incorporated into the kinematics formulation to simulate direct writing and three‐dimensional printing scenarios. Constraints describing viscoelastic joints in the system and the phenomenon of the melt‐electrospun fiber adhering to the collector plate are implemented using the Udwadia Kalaba method. Rotational viscoelastic elements are introduced to mimic the dampening of the whipping motion observed in the unstable region. A novel algorithm is devised to continuously run the simulation with no limit on the total duration and phase transitions. System responses such as fiber diameter, collection size, fiber elongations, and jet speeds are monitored for changes in control parameters including applied voltage, collector distance, and flowrate. The results demonstrate close agreement with experimental observations in the literature. The jet starts relatively straight on the onset of its trajectory and develops subtle whipping motion as it advances toward the collector plate. Reduction in the amplitude of the whipping motion is observed once the free end of the fiber adhered to the collector plate.

Published: January 2022

AbstractCommensurable twisted bilayers can drastically change the magnetic properties of chromium trihalide layered compounds, which opens novel opportunities for tuning magnetic states through layer rotations. Here, a mathematical approach to obtain moiré patterns in twisted hexagonal bilayers by performing a certain commensurable rotation θ over one layer is presented. To test the approach, moiré structures with and 32.20° in the phases R and C2/m of CrI3 are obtained via the related methodology. For comparison purposes, a non‐shifted CrI3 structure is also considered. Electronic and magnetic properties of the so‐obtained systems are computed by ab initio methodologies. Results show the presence of rotation‐angle‐dependent magnetic configurations and steep modifications of the dispersion bands due to variations in the nearest and next nearest distances among layers of Cr atoms. Modifications obtained from these commensurable rotations are discussed on the basis of competition among different energy contributions due to changes in the atomic neighborhood.
Adaptive Backstepping Sliding Mode Tracking Control For Autonomous Underwater Vehicles With Input Quantization
Authors: An Shun , Wang Longjin , He Yan , Yuan Jianping 
Published: January 2022

AbstractThis paper proposes an adaptive backstepping sliding mode control (ABSMC) scheme for autonomous underwater vehicles (AUVs) subject to the dynamic uncertainty, external disturbance and quantization error. The control input signals including control forces and moment are quantized by a hybrid quantizer which is the combinination of a logarithmic quantizer and a uniform quantizer. The kinematic controller is designed by the backstepping control technique and the dynamic controller is developed using the sliding mode control method. In order to further improve the robustness of the closed‐loop system, an adaptive law is employed to estimate the upper bound of the total uncertainties in real time. The stability of the closed‐loop system is proved based on the Lyapunov theory and indicates that the proposed control method can force the AUV to track the desired trajectory. Simulation results demonstrate the effectiveness of the proposed control strategy.

Published: January 2022

AbstractSolitons in the fractional space, supported by lattice potentials, have recently attracted much interest. The limit of deep 1D and 2D lattices in this system is considered, featuring finite bandgaps separated by nearly flat Bloch bands. Such spectra are also a subject of great interest in current studies. The existence, shapes, and stability of various localized modes, including fundamental gap and vortex solitons, are investigated by means of numerical methods; some results are also obtained with the help of analytical approximations. In particular, the 1D and 2D gap solitons, belonging to the first and second finite bandgaps, are tightly confined around a single cell of the deep lattice. Vortex gap solitons are constructed as four‐peak “squares” and “rhombuses” with imprinted winding number . Stability of the solitons is explored by means of the linearization and verified by direct simulations.
