Published: April 2022

AbstractRemote sensing (RS) and Geographic Information Systems (GIS) have become widely used in various fields around the world in recent years. In this paper; we attempt to delineate the groundwater potential zone in the transboundary watershed of Chott-El-Gharbi using the integration of RS, GIS methods. Eight influencing thematic layers viz. geology, rainfall, water table level, lineaments density, slope, drainage density, elevation, and land use/land cover were used. Afterward, Analytical Hierarchy Process technique, which offers good functionality for mapping the groundwater potentiality was used, where ranks and weights, assigned to each factor are computed statistically, based on their relative importance in terms of groundwater potential. Then, groundwater potential zones are classified into five categories namely excellent, high, medium, low, and very low zone, which represent 964.48 km2 (7.33%), 1467.30 km2 (11.15%), 7969.51 km2 (60.57%), 2639.52 km2 (20.06%), and 116.19 km2 (0.88%) of the study area, respectively. The very low potential region is found in the southern region of the study area, which is covered by mountains. Moreover, excellent groundwater potential zones are located at the central part of the region of Chott, which has quaternary formations where the infiltration is high. On the other hand, moderate and poor groundwater potential zones cover by the bare lands in the study area. Finally, the results were carefully validated with the yields data of various boreholes in the study area, which reveals an accuracy achievement of 72.41%. The finding of this research constitutes a valuable contribution towards the water resources management, and it forms a significant decision support tool for equitable and sustainable utilization of groundwater resources in the transboundary watershed of Chott-El-Gharbi. The study's findings will also serve as a benchmark for future research and studies, such as hydrogeological modeling.

AbstractTo compare outcomes between single-incision laparoscopic totally extra-peritoneal sub-lay (SIL-TES) mesh repair and laparoscopic intraperitoneal onlay mesh (IPOM) repair of ventral hernia (VH). A retrospective selection of 104 patients who underwent VH repair (50 and 54 in the SIL-TES and IPOM groups, respectively) was made. Patient data were collected, and quality of life was evaluated using Carolinas Comfort Scale (CCS) 1 month and 3 months after surgery. There were no significant differences in sex, American Society of Anesthesiologists class, defect size, mesh area, estimated blood loss, and complication rate between the groups. Age was lower, body mass index was higher, prevalence of primary VH was significantly higher (p < 0.0001), and pain was less at 24 and 48 h post procedure (p < 0.0001) in the SIL-TES group. Drainage placement was more (p < 0.0001), operation time was shorter (p = 0.012), and hospitalization duration and total hospitalization cost were greater in the IPOM group than that in SIL-TES group (8.3 ± 0.3 vs 4.3 ± 0.4 days, p < 0.0001; $7126.9 ± 141.4 vs $2937.3 ± 58.3, p < 0.0001, respectively). Pain and movement limitation scores evaluated by CCS were significantly worse at 1 month (4.93 ± 0.28 vs 1.75 ± 0.28: p < 0.0001; 2.52 ± 0.24 vs 1.15 ± 0.18: p < 0.0001, respectively) and 3 months (4.32 ± 0.37 vs 0.9 ± 0.29: p < 0.0001; 2.06 ± 0.25 vs 0.69 ± 0.11: p < 0.0001, respectively) in IPOM group, compared with the according scores in SIL-TES group. There was no readmission within 30 days and no hernia recurrence at mean follow-up of 12 months. SIL-TES mesh repair is safe and effective and is superior to IPOM repair.
Understanding Technology-Induced Value Change: a Pragmatist Proposal
Authors: van de Poel Ibo , Kudina Olya 
Published: April 2022

Abstract
We propose a pragmatist account of value change that helps to understand how and why values sometimes change due to technological developments. Inspired by John Dewey’s writings on value, we propose to understand values as evaluative devices that carry over from earlier experiences and that are to some extent shared in society. We discuss the various functions that values fulfil in moral inquiry and propose a conceptual framework that helps to understand value change as the interaction between three manifestations of value distinguished by Dewey, i.e., “immediate value,” “values as the result of inquiry” and “generalized values.” We show how this framework helps to distinguish three types of value change: value dynamism, value adaptation, and value emergence, and we illustrate these with examples from the domain of technology. We argue that our account helps to better understand how technology may induce value change, namely through the creation of what Dewey calls indeterminate situations, and we show how our account can integrate several insights on (techno)moral change offered by other authors.

The Mediating Impact of IT Capabilities on the Association between Dynamic Capabilities and Organizational Agility: The Case of the Jordanian IT Sector
Authors: Awwad Abdulkareem Salameh , Ababneh Omar Mohammed Ali , Karasneh Mahmoud 
Published: April 2022

AbstractThis study suggests a novel progression to the current research endeavor by investigating the influence of information technology capabilities on organizational agility. More specifically, this study aims to fill the gaps found in previous studies and contribute to the current state of knowledge of this domain by focusing on the mediating role that IT capabilities play between dynamic capabilities and organizational agility. Toward that end, 270 Jordanian professionals working in supply chain management and operational departments were approached. Data were collected via distrusting a structured questionnaire that includes items assessing dynamic capabilities, IT capabilities, and organizational agility. The results demonstrated that IT capabilities significantly and positively mediated the relationship between resource-based dynamic capability and organizational agility. The study has also discussed several theoretical along with managerial implications of the research.
Two-step peer methods with equation-dependent coefficients
Authors: Conte Dajana , Pagano Giovanni , Paternoster Beatrice 
Published: April 2022

AbstractWe introduce a new class of explicit two-step peer methods with the aim of improving the stability properties of already existing peer methods, by making use of coefficients depending on the Jacobian of the Ordinary Differential Equations (ODEs) system to solve. Numerical tests highlight the best stability and accuracy properties of the new methods compared to the classical and equation-dependent ones proposed in Conte et al. (Lect Notes Comput Sci 12949:309–324, 2021).
Relationship between microstructure, mechanical and magnetic properties of pure iron produced by laser powder bed fusion (L-PBF) in the as-built and stress relieved conditions

Published: April 2022

AbstractIn the present work, the mechanical and magnetic properties of pure iron manufactured by laser-powder bed fusion (L-PBF) were investigated both in the as-built (AB) and stress relieved (HT) conditions, with the aim of elucidating their relationship with the microstructure and evaluating whether and to what extent it can be suitable for industrial applications. The L-PBF process was optimized to obtain high density, crack-free components. Specimens for microstructural analyses, tensile and magnetic tests were manufactured under the optimized conditions and tested both in the as-built and annealed (850 °C for 1 h, to relieve the residual stresses) conditions. Tensile tests showed high tensile strength in both AB and HT conditions (larger than those of conventionally produced pure iron), with higher ductility and lower strength after stress relieving. The magnetic study indicated a not optimal magnetic softness although the heat treatment enhanced the permeability and reduced the coercivity with respect to the as-built condition. The high mechanical strength and low magnetic softness came from the very fine grain size (about 5 μm) of L-PBF pure iron. Instead, the improvement of magnetic softness and ductility after heat treatment was attributed to the possible reduction of dislocation density and consequent stress relief. The results indicated the possibility to achieve a considerably high mechanical strength, in pure iron manufactured by L-PBF, although the fine grain size limits its magnetic softness.
Ketamine treatment for depression: a review
Authors: Yavi Mani , Lee Holim , Henter Ioline D. , Park Lawrence T. , Zarate Carlos A. 
Published: April 2022

AbstractThis manuscript reviews the clinical evidence regarding single-dose intravenous (IV) administration of the novel glutamatergic modulator racemic (R,S)-ketamine (hereafter referred to as ketamine) as well as its S-enantiomer, intranasal esketamine, for the treatment of major depressive disorder (MDD). Initial studies found that a single subanesthetic-dose IV ketamine infusion rapidly (within one day) improved depressive symptoms in individuals with MDD and bipolar depression, with antidepressant effects lasting three to seven days. In 2019, esketamine received FDA approval as an adjunctive treatment for treatment-resistant depression (TRD) in adults. Esketamine was approved under a risk evaluation and mitigation strategy (REMS) that requires administration under medical supervision. Both ketamine and esketamine are currently viable treatment options for TRD that offer the possibility of rapid symptom improvement. The manuscript also reviews ketamine’s use in other psychiatric diagnoses—including suicidality, obsessive–compulsive disorder, post-traumatic stress disorder, substance abuse, and social anxiety disorder—and its potential adverse effects. Despite limited data, side effects for antidepressant-dose ketamine—including dissociative symptoms, hypertension, and confusion/agitation—appear to be tolerable and limited to around the time of treatment. Relatively little is known about ketamine’s longer-term effects, including increased risks of abuse and/or dependence. Attempts to prolong ketamine’s effects with combined therapy or a repeat-dose strategy are also reviewed, as are current guidelines for its clinical use. In addition to presenting a novel and valuable treatment option, studying ketamine also has the potential to transform our understanding of the mechanisms underlying mood disorders and the development of novel therapeutics.

AbstractKinetic‐size magnetic holes (KSMHs) can accelerate and heat the particles, resulting the energy dissipation in space plasmas. KSMHs in the terrestrial foreshock region are statistically investigated based on the Magnetospheric Multiscale data from October 2015 to December 2019. A total of 98 KSMHs are successfully selected, and most of them are accompanied by electron vortices. The fluxes of electrons at ∼90° of pitch angle enhance inside the magnetic holes, where the perpendicular and total electron temperature increase, and the parallel electron temperature slightly decreases inside these magnetic holes. Moreover, we reveal a novel phenomenon that a lot of the observed KSMHs are probably moving toward the Sun in the plasma flow frame. Such sunward propagating KSMHs are detected for the first time in the foreshock region. We propose that these observed KSMHs are probably generated in the foreshock region and then propagate to the Sun.

Published: April 2022

AbstractInterpretation of fault slip‐rates inferred from tectonically offset fluvial landforms is often limited by uncertainties associated with difficulties to explicitly date fluvial incision across the fault. Here, we employed morphology‐based modeling to ameliorate this universal dating limitation for gullies that were differentially offset in a sinistral sense across the Altyn Tagh Fault near its eastern termination at ∼97°E. Using a stream‐power erosion model with locally calibrated coefficients we calculated across‐fault gully incision ages that decrease with offset magnitude, are up to threefold younger than the age of the terrace they incised and all‐together point toward time‐invariant slip. Luminescence dating of offset alluvial terraces at the same site suggests constant sinistral slip at 0.5 ± 0.1 mm/yr since 52 ± 4 ka. Our results suggest that the most juvenile phase of northeastward Pleistocene expansion of the Tibetan Plateau into previously stable parts of central Asia is marked by constant late Quaternary deformation rates.
Analytical Prediction of Scattering Properties of Spheroidal Dust Particles With Machine Learning

Published: April 2022

AbstractA neural network (NN) model is trained with a database widely used in the aerosol remote sensing community to rapidly predict the single‐scattering optical properties of spheroidal dust particles. Analytical solutions for their Jacobians with respect to microphysical properties are derived based on the functional form of the NN. The Jacobian predictions are improved by adding Jacobians from a linearized T‐matrix model into the training. Out‐of‐database testing implies that NN‐based predictions perform better than the business‐as‐usual method that interpolates optical properties from the database. Independent validation further demonstrates the efficacy of the NN‐based predictions by reducing computational costs while maintaining accuracy. This work represents the first use of machine learning‐based function approximation to computationally expedite the application of the existing spheroidal dust properties database; the resultant NN model can be implemented in atmospheric models and satellite retrieval algorithms with high accuracy, computational efficiency, and the rigor of analytical solutions.
Greenstone‐Up Shear Sense at the Margin of the Mt Edgar Dome, East Pilbara Terrane: Implications for Dome and Keel Formation in the Early Earth
Authors: Roberts Nicolas M. , Tikoff Basil , Salerno Ross A. 
Published: April 2022

AbstractThe Paleoarchean Mt Edgar dome in the East Pilbara Terrane has long been studied as an archetypal dome within Archean dome‐and‐keel terranes, but the history of its formation is debated. Kinematic data presented in this study provide new insights into the late‐stage development of the Mt Edgar dome and East Pilbara Terrane. Quartz crystallographic preferred orientation (CPO), optical microstructures, and field structures all indicate that the granite‐greenstone contact of the Mt Edgar dome experienced reverse (greenstone‐up, dome‐down) sense of shear after the formation of the dominant schistosity. This reverse sense of shear is observed at localities along the entire extent of the sheared margin that rings most of the Mt Edgar dome, but is best documented along the southwest margin in the Warrawoona Greenstone Belt. Additionally, quartz CPO data from a dome triple junction outside of the sheared margin dominantly indicate a constrictional strain geometry, consistent with the previous interpretation that this area represents a zone of vertical foundering in a buoyancy‐instability driven system. However, buoyancy‐instability models do not necessarily predict the occurrence of greenstone‐up sense of shear preserved in solid‐state fabrics along the dome margin. Several geologic explanations are considered, including dome expansion or post‐doming deformation. The data are most consistent with explanations that directly relate to dome formation, especially when considered in tandem with recently published structural data from within the Mt Edgar dome. These kinematic data suggest that late dome development occurred in a near‐static crustal environment rather than an extensional or contractional setting.

AbstractLava tubes on Mars hold exciting potential for the preservation of biosignatures, which may survive on geological timescales in these isolated, stable environments. To support the development of future astrobiological mission concepts, we turn to terrestrial lava tubes, host to a variety of microbial communities and secondary minerals. Following a multidisciplinary sampling protocol, we retrieved biological, molecular, and mineralogical data from several lava tubes in Iceland. We report on blue‐colored copper‐rich secondary minerals and their associated bacterial communities using a multi‐method approach, and an amalgam of 16S rRNA gene sequencing, Raman spectroscopy, scanning electron microscopy, and energy‐dispersive X‐ray spectroscopy data sets. We found numerous bacterial genera known for their high metal resistance and ability to survive in low‐nutrient environments. Both are characteristics to be expected for any potential life in Martian lava tubes, and should be considered when checking for contaminants in Mars mission preparations. Associated with the microbial mats, we identified several types of copper‐rich secondary minerals, indicating localized copper enrichments in the groundwater, possibly stemming from overlying ash deposits and nearby hyaloclastite formations. Molecular analysis revealed carotenoid signals preserved within the copper speleothems. If found in Martian lava tubes, blue copper‐rich mineral precipitates would be deserving of astrobiological investigation, as they have potential to preserve biosignatures and harbor life.
Tropical and Subtropical Pacific Sources of the Asymmetric El Niño‐La Niña Decay and Their Future Changes

Published: April 2022

AbstractEl Niños (EN) are known to decay more rapidly, while La Niñas (LN) tend to decay more slowly. Observational analyses and coupled model experiments are conducted to show that sea surface temperature (SST) anomalies over the subtropical northeastern Pacific (SNEP) and equatorial western Pacific (EWP) are key factors to determine the decay pace of the EN and LN and their asymmetry. In the present climate the LN produces larger cold SST anomalies over the regions than the warm SST anomalies produced by the EN. The magnitude difference over the SNEP and EWP helps to slow down the LN decay via subtropical footprinting and tropical thermocline variation mechanisms, respectively. Coupled Model Intercomparison Project Phase 6 models project the magnitude differences of SNEP SST anomalies between EN and LN to reduce in the future warming world, causing the asymmetric EN‐LN decay to weaken.

AbstractWe present the first observations of electrostatic solitary waves with electrostatic potential of negative polarity around a fast plasma flow in the Earth's plasma sheet. The solitary waves are observed aboard four Magnetospheric Multiscale spacecraft, which allowed accurately estimating solitary wave properties. Based on a data set of 153 solitary waves, we show that they are locally one‐dimensional Debye‐scale structures with amplitudes up to 20% of local electron temperature and they propagate at plasma frame speeds ranging from a tenth to a few ion‐acoustic speeds at arbitrary angles to the local magnetic field. The solitary waves are associated with multi‐component proton distributions and their velocities are around those of a beam‐like proton population. We argue that the solitary waves are ion holes, nonlinear structures produced by ion‐streaming instabilities, and conclude that once ions are not magnetized, ion holes can propagate oblique to local magnetic field.

Published: April 2022

AbstractHydrogen storage is a main issue in the establishment of a hydrogen economy. Geo‐storage could be a viable solution if hydrogen could be injected into and withdrawn from suitable geological formations, reversibly and reliably. Rock wettability is a major factor as it affects injectivities, withdrawal rates, storage capacities, and containment security. We report here the contact angles of a brine on the surface of a bituminous coal in a pressurized hydrogen atmosphere. Under realistic geo‐storage conditions the coal surface was weakly water‐wet. Hydrogen pressure increased brine contact angles at 25°C but did not have an impact at 50 or 70°C. We present a thermodynamic model that describes the observed behavior. Our results would support the development of large‐scale geo‐storage technologies for hydrogen.
