Does going abroad lead to going green? Firm outward foreign direct investment and domestic environmental performance
Authors: Long Wenbin , Luo Le , Sun Hongfeng , Zhong Qiqi 
Published: June 2022

AbstractThis study examines whether and how outward foreign direct investment (OFDI) affects firms' domestic environmental performance. We use both the reverse knowledge transfer and resource crowding perspectives to predict the association. Using a sample of Chinese firms, we find that firms' environmental performance improves after the initiation of OFDI, which is consistent with the reverse knowledge transfer perspective. Furthermore, we find that when the host countries of OFDI are developed countries, have stricter environmental regulations, and are characterized by higher values for the long‐term orientation and masculinity dimensions of national culture, firms enjoy a further improvement in environmental performance. Our channel tests show that firms' domestic green patent applications and their investment in research and development increase after the initiation of OFDI.

Guar resilience in water‐restricted production
Authors: Pabuayon Irish Lorraine Bicaldo , Singh Sukhbir , Ritchie Glen 
Published: June 2022

AbstractGuar [Cyamopsis tetragonoloba (L.) Taub] is an alternative crop in the Southern High Plains that thrives in semi‐arid regions, due to its low water input requirements. Field experiments were conducted in 2017 and 2018 at New Deal, TX, to evaluate the response of guar (‘Matador’) to four levels of deficit irrigation (DI; extreme, 51 mm; severe, 127 mm; moderate, 203 mm; and mild, 279 mm). Soil moisture extraction patterns, plant height, leaf area index, yield components, seed yield, harvest index (HI), agronomic water use efficiency (AWUE), and irrigation WUE (IWUE) were measured among the irrigation levels. In both years, guar grown under extreme and severe DI extracted a major portion of the water from the 50‐to‐100‐cm soil depth. Water deficit reduced plant height, leaf area index, and number of pods per plant in both years. However, the IWUE and 1,000‐seed weight increased with reduced irrigation. There were no significant differences in seed yield, HI, and AWUE among treatments as a result of a tradeoff between increased seed weight with low pod production under lower DI treatments and increased pod production with low seed weight under higher DI treatments. Guar extracted water deeper in the soil and produced adequate numbers of pods per plant in balance with the source organ capacity to allocate resources toward optimal seed development. Our research offers valuable information about root exploration and development of larger seeds as compensatory mechanisms that can be further explored to improve the adaptability of guar under water‐restricted production conditions.
Design of a quality of service‐aware fault‐proof secure Q‐learning‐based Internet of Things kernel patch with multipath and multichannel capabilities
Authors: Vijayrao Shankhpal Shilpa , Savadatti Hanumantha Brahmananda 
Published: June 2022

SummaryIn recent times, the expeditious growth of Internet of Things (IoT) offers applications to ease day‐to‐day activities with minimum human effort. Once the IoT application installed, the connected devices perform their tasks without human intervention. Hence, the need of performance optimization and security enhancement is vital to minimize end‐to‐end communication delay, improve kernel‐level security, mitigate faults adaptively, and have suitable backup options in case of node failure. This paper proposes a quality of service (QoS)‐aware fault‐proof secure Q‐learning‐based IoT (QIoT) kernel‐level protocol that integrates multipath aggregation and fuzzy authentication for security, with multichannel communication for improved QoS. Especially, this protocol integrates a source‐level clustering mechanism based on Q‐learning that aims at reducing route search delay. In order to provide fault tolerance, the kernel is equipped with real‐time fault‐tolerance mechanism that is activated in case of node‐level faults. Due to integration of Q‐learning, computational overheads are reduced by over 15% when compared with Zephyr, AliOS, and RTX kernels. This reduction in computational overheads facilitates light‐weight behavior of the kernel, due to which other QoS parameters like energy consumption, throughput, and routing overhead are reduced. The proposed QIoT kernel‐level protocol is compared with standard kernel modules, and performance evaluation showcases an improvement in authentication security by 8%, end‐to‐end delay by 5%, energy efficiency by 25%, and fault mitigation by 18%, thereby assisting the use of the proposed kernel for real‐time deployments.
Self‐adjusting steepness based remapping: A preliminary study
Authors: He Zhiwei , Li Li , Tian Baolin 
Published: June 2022

AbstractNonlinear limiters are used to obtain the non‐oscillation property in the process of remapping physical quantities (mapping the physical quantities from the old grid to the new grid), which is an important step in the single/multimaterial arbitrary Lagrangian–Eulerian method. However, this operation introduces large numerical dissipation, causing severely smeared physical discontinuities and distortion of the physical quantities. Therefore, the design of an effective limiter that has less numerical dissipation and preserves the sharpness of discontinuous solutions is an area of interest. In this article, we apply the steepness‐adjustable harmonic (SAH) limiter (containing a steepness parameter) to the overlay‐intersection‐based remapping trying to obtain this goal. First, we analyze the construction process of the Barth–Jespersen (BJ) limiter and find a general methodology to modify it with different functions with symmetry property in the existing total‐variation‐diminishing limiters. Second, we investigate the possibility of other functions that do not possess the symmetry property and find an approximate technique to utilize the SAH limiter (which also does not possess the symmetry property) in the general methodology. Third, we propose a multidimensional method to adaptively calculate the steepness parameter of a whole mesh cell. With these steps, we propose a self‐adjusting steepness‐based limiter, which is further applied to the over‐intersection‐based remapping framework. The limiter is then verified by several remapping tests. The numerical results demonstrate a significant improvement in the resolution of discontinuities and the preservation of nominal second‐order accuracy for smooth structures. However, the bound‐preserving property is inevitably broken owing to the asymmetry of the SAH limiter, and additional techniques should be used to enforce the bounds of the algorithm.
Heat and mass transfer on unsteady MHD flow of Casson fluid over an infinite perpendicular absorbent plate with slip effects
Authors: Ameer Ahammad N. , Veera Krishna M. , Algehyne Ebrahem A. 
Published: June 2022

AbstractWe study the radiative magnetohydrodynamic flow of an incompressible viscous electrically performing non‐Newtonian Casson fluid past an exponentially accelerated perpendicular surface under the influence of slip velocity in the revolving frame. A steady homogeneous magnetic strength is applied under the assumption of a less magnetic Reynolds number. The ramped temperature and time‐altering concentration near the plate are taken into consideration. Primary order consistent chemically reacting and thermal absorptions are also considered. Laplace transformation technique is engaged in the nondimensional leading equations for the closed‐form solutions. Supporting these results, the phases for nondimensional shear stresses, rate of heat as well as mass transport are also found. The graphical profiles are represented to examine the impacts of physical parameters on the important physical flow features. The computational quantities of the shears stress, rates of heat as well as mass transportation near the surface are tabulated with a variety of implanted parameters. It is observed that the resultant velocity is growing by an increase in heat and solutal buoyancy forces, while revolution, as well as slip parameters, has reverse outcomes on this. The resulting velocity is falling by an increase in the Hartmann number while the permeability parameters have overturned the impacts on this. Species concentration of Casson fluid is reduced by an increase in Schmidt quantity as well as a chemically reacting parameter.
Impacts of frozen layer and rock fragment on sediment transport capacity on frozen‐stony slopes
Authors: Ban Yunyun , Lei Tingwu 
Published: June 2022

AbstractCold areas commonly experienced freeze–thaw cycles and covered with rock fragment. Exploring sediment transport capacity of frozen‐stony soil scoured by concentrated meltwater flow is meaningful for soil erosion prediction and modelling in cold regions. This laboratory experiment is conducted to evaluate the contribution of frozen layer and rock fragment to soil erosion, which involves three slope gradients of 5°, 10°, and 15°, three flow rates of 1, 2, and 4 L min−1, four thawed soil depths of 1, 2, 5, and 10 cm, and four rock fragment contents of 0%, 10%, 20%, and 50% on mass basis with rill length of 12 m. Sediment concentration was determined by the soil in runoff at the outlet. An equation is proposed to estimate sediment transport capacity affected by thawed soil depth and rock fragment content by combining exponential and quadratic functions. Model‐fitting results show that sediment transport capacity is negatively correlated with thawed soil depth and exhibits quadratic relationship with rock fragment which peaks at 20% and significantly decreases at rock fragment of 50% on partially thawed slope. Rock fragment takes the leading role of soil erosion on frozen‐stony slope instead of thawed soil depth. Results also indicate that embedded rock fragment on totally thawed soil presents more apparently positive impact at low content, but offers more protection at high content on partially frozen layer. This research reveals the soil erosion mechanisms on frozen‐stony slope and gives guidance for soil conservation in similar hydrologic conditions and soil type.
Environmental flow mechanism and management for river–lake‐marsh systems
Authors: Yin Xinan , Hu Peng , Zhou Jianguo 
Published: June 2022

AbstractSustaining environmental flows (e‐flows) is a basic requirement for river, lake and marsh management. Rivers, lakes and marshes have close hydrological and ecological connections in a river basin, and form river–lake‐marsh systems. Any measure that is designed to address problems related to only one of these water bodies in isolation of the others may lead to unexpected, undesired and sub‐optimal consequences for one or all of the water bodies. Papers were selected for this special issue ‘Environmental Flow Mechanism and Management for River‐Lake‐Marsh Systems’ to illustrate recent advances in revealing new mechanisms connecting hydrological and environmental/ecological processes, developing new methods for e‐flow calculation, and establishing new measures for e‐flow management.

AbstractQuetiapine fumarate (QF) is an antipsychotic drug that has been most widely prescribed as an antipsychotic. In this regard, sensitive recognition of QF in bodily fluids must be done accurately. In this work, an electrochemical sensor for QF detection was fabricated, using GNSs‐PDA@SiO2 modified rGO stabilized on glassy carbon electrode. According to the electrical nature of gold nanoparticles (GNPs), polydopamine (PDA), and its composition with nano‐silica, the proposed hybrid material is able to enhance the electro‐oxidation signals of QF toward its sensitive detection in complex biological media. The morphology of synthesized polymeric nanocomposites and various surfaces of electrodes were investigated using Field Emission Scanning Electron Microscopy and Energy‐Dispersive X‐Ray Spectroscopy methods. Using the square wave voltammetry technique, the fabricated electrochemical sensor could detect QF in the linear range of 500 μM to 3 mM, which low limit of quantification was obtained as 500 μM, indicating the sensor's appropriate sensitivity. For the first time, the application of novel hybrid material (GNSs‐PDA@SiO2) for pharmaceutical analysis in human plasma was studied using electrochemical sensor technology. Based on the obtained analytical results, engineered nano‐surface led to entrapment and oxidation of QF in real samples. So, a novel and efficient method for the analysis of QF was designed and validated, which opens a new horizon for pharmaceutical analysis and therapeutic drug monitoring.
Nevertheless, she persisted: Feminist women overcoming career adversity through communities of support
Authors: Diekmann Kerry 
Published: June 2022

AbstractThrough an Interpretative Phenomenological Analysis design, this study explored career experiences of eight self‐identified feminist women. This study contributes to existing literature through focusing on the intersection of feminist identity and career development. The findings indicated that having a community of support, particularly from other women, is influential in career progression. All participants noted adversity, however, they recognized when situations were either sexist or unfair and did not appear to internalize these experiences. Implications include making space to discuss the impact of social identities on life decisions, prioritizing inclusive environments that mitigate adversity, and fostering communities of support.

AbstractBACKGROUNDAs a potential selenium‐enriched crop, it is of great significance to study the selenium application of Tartary buckwheat. Therefore, to study the effects of selenium application concentration, variety, selenium application period and method on the grain selenium content and yield of Tartary buckwheat, an orthogonal experimental design was used to carry out field experiments in the Jinzhong and Northwest Shanxi ecological regions at the same time. Heifeng 1 and Jinqiao 2 were applied at the branching stage and flowering stage in the Jinzhong, and Heifeng 1 and Jinqiao 6 were applied at the early flowering stage and peak flowering stage in the Northwest Shanxi with different concentrations of sodium selenite (0, 1.37, 2.74, 5.48, 8.22, 12.33, 18.495, 27.7425 g hm−2) by foliar spraying and soil application.RESULTSThe results showed that the selenium content in Tartary buckwheat grains was positively correlated with the selenium application concentration and increased with increasing selenium application concentration, while the yield of Tartary buckwheat first increased and then decreased with the selenium application concentration. The grain selenium content and yield of Tartary buckwheat were affected by the selenium application concentration, variety and application method.CONCLUSIONThe most effective selenium biofortification program was spraying 2.32 g hm−2 sodium selenite on the leaves of Heifeng 1 at the early flowering stage in the Jinzhong. In the Northwest Shanxi, spraying 11.01 g hm−2 sodium selenite on the leaves of Jinqiao 6 at the flowering stage was the most effective selenium biofortification program. © 2022 Society of Chemical Industry.

Published: June 2022

AbstractCommon bean (Phaseolus vulgaris L.) is the main source of protein, fiber, and iron for Guatemala's poorest households. Bean rust (caused by Uromyces appendiculatus (Pers) Unger) can reduce seed yield up to 100%. There is limited information about U. appendiculatus virulence diversity in Guatemala, especially in the mid‐altitude highlands. To address this limitation, in 2015, 23 U. appendiculatus samples were collected in the Western Guatemalan Highlands and characterized as races 63‐1 and 31‐1 using the rust differential set. These two races, along with the newer race 20‐3 found in North Dakota, were used to evaluate the reaction in 372 climbing bean accessions from Guatemala. Most of the accessions were resistant: 82% to race 63‐1, 86% to race 31‐1, and 90% to race 20‐3. Based on a genome‐wide association study (GWAS) using 78,754 single nucleotide polymorphisms (SNPs), regions on Pv02 (38.13–38.22 Mb) and Pv04 (379 kb) were associated with resistance to race 20‐3; on Pv10 (10.71–10.68 and 11.09 Mb) and Pv04 (1.42 Mb) to race 63‐1; and on Pv04 (39.28 Mb) along with Pv02 (35.92 Mb) to race 31‐1. The regions on Pv04: 379 kb, 1.42 Mb and 39.28 Mb felt close to the genetic block B‐190, containing Ur‐5 and Ur‐14. Moreover, previously unreported genetic factors for bean rust resistance located on Pv02 (38.13–38.22 Mb), Pv10 (10.71–10.68 Mb), and Pv02 (35.92 Mb) were observed in this population and may prove useful for bean improvement. Using these bean rust‐resistant Guatemalan accessions as parents in a crop improvement program will help to maintain seed yield where the bean rust pathogen is present.

Authors: Pahlavani Mahmoud A. , Moradkhani Masoud , Sayadi Ramin 
Published: June 2022

AbstractA high‐performance Gysel power divider showcasing high suppression factor and low insertion loss at 540 MHz has been designed, investigated, and fabricated in this paper. The proposed Gysel power divider is made up of replacing six identical resonators with conventional transmission lines. The proposed resonators, which have been analyzed using LC equivalent circuit analysis, are designed to have a small size, low insertion loss, wide stopband, and narrow transition band. The final tested results have indicated that the suggested power divider is able to suppress nine harmonics; moreover, it has only an insertion loss of 0.4 dB. Another positive feature of the power divider is its small size in comparison with a conventional power divider at this operating frequency, where it occupies 34.5 × 63.8 mm2equaling to 0.188 × 0.102 , where is the wavelength guide at 540 MHz. This figure is 25% of a conventional Gysel, considered as a remarkable point.
Near‐surface three‐dimensional multicomponent source and receiver S‐wave survey in the Tannwald Basin, Germany: Acquisition and data processing
Authors: Burschil Thomas , Buness Hermann , Schmelzbach Cedric 
Published: June 2022

ABSTRACTShallow 3‐D reflection seismic surveys using S‐waves have rarely been carried out, even though S‐waves can provide higher resolution subsurface images than P‐waves. We conducted a 3‐D near‐surface multicomponent source and receiver survey in Quaternary sediments. We employed a small electrodynamic seismic source with a horizontal shaking unit operated in two orientations. Three‐component geophones in an orthogonal layout covering an area of 117×99 m2 were used for recording. Changes in weather and ground conditions, including freezing and thawing during acquisition, directly influenced the data quality and resulted in discernible relative time shifts in the data. Our seismic processing flow included a four‐component rotation of the data from the Cartesian acquisition geometry into the ‘natural’ coordinate frame to orient sources and receivers in radial or transverse orientation to separate different S‐wave polarizations. The rotation increased the signal strength and helped, for example, to improve the quality of the images of the basin base. The irregular offset distribution in the common midpoint gathers impedes filtering to suppress surface waves in the f–k domain. We, therefore, applied a common‐reflection surface processing flow. After regularization, we could better remove the energy of the surface waves. Both stacked 3‐D S‐wave volumes of vertical and horizontal polarizations provide images of the Quaternary overdeepened Tannwald Basin that was partly known from previous P‐ and S‐wave 2‐D surveys. Compared to a P‐wave profile adjacent to the volume, however, the S‐wave volumes provide higher resolution images of the basin base and internal structure. The basin base is well mapped in three dimensions and shows undulations that were not obvious from the P‐wave data. Comparing the S‐wave volumes of different polarizations, we find only minor differences in the stacks and interpretations.
