Liquidity Shocks and The Bank Lending Channel: Evidence from Lower-Middle Income Economies
Authors: ISSAOUI Ibtissem , NABI Mahmoud-Sami
Published: November 2022

This paper examines the impacts of central banks’ liquidity injections on commercial banks’ credit supply in thirty-two lower-middle income economies over the period 1990 until 2020. We use a SVAR panel model to analyze the dynamic interactions between the central bank balance sheet policy, bank liquidity, and bank lending. The results show that liquidity injections have a non-significant impact on the credit to the private sector and a persistent positive impact on banks’ liquid reserves. These results confirm the inefficiency of the bank lending channel in transmitting the central bank balance sheet monetary policy to the real economy in the considered LMIC’s.
Probabilistic Modeling of Negative-Sequence Current in Three-Phase Power Systems with Statistically Unbalanced Phases
Authors: Bellan Diego
Published: November 2022

In this work the parameters of an unbalanced three-phase component, such as a load or a transmission line, are described as random variables with known statistical properties. It is well-known that phase unbalancing leads to injected current in the negative-sequence circuit producing propagation of voltage unbalance and malfunctioning of power system components. In this paper, the injected current is described in probabilistic terms as a function of the statistical properties of the component unbalancing. In particular, approximate expressions for the probability density function, the mean value, and the variance of the injected current are derived in closed form and numerically validated.

Balãmedžių (lot. Tabebuia sp.) genties augalų biologinio aktyvumo tyrimų apžvalga. Arba – kiek stebuklų galime rasti skruzdžių medyje?
Authors: Balčiūnaitė­-Murzienė Gabrielė
Published: November 2022

Įvairialapiai balãmedžiai bei penkialapiai balãmedžiai geriau žinomi Pau d’Arco arba skruzdžių medžio pavadinimu. Tradicinio šio vaistinio augalo vartojimo žinios kildinamos iš Brazilijos indėnų genčių. Manoma, kad jų tradicinės medicinos žinios paplito ir į kitas Pietų Amerikos dalis ir atėjo iki mūsų laikų. Balãmedžiai žaibiškai išpopuliarėjo po to, kai 1967 m. kovo mėn. Brazilijoje populiarus naujienų žurnalas O’Cruzeiro paskelbė publikaciją apie stebuklingus išgijimus nuo vėžio San Paulo ir Santo Andre ligoninėse. Po keletos metų JAV Nacionalinis vėžio institutas pradėjo didelės apimties tyrimą su balãmedžių vaistinėse augalinėse žaliavose kaupiamais cheminiais junginiais, siekdami atrinkti didžiausiu priešvėžiniu aktyvumu pasižyminčius junginius. Dar ir šiandien manoma, kad šis augalas – stebuklingas. Artėjant šaltajam metų laikui, pacientai vastinėse vis dažniau teiraujasi iš šio vaistinio augalo pagamintų preparatų tiek sau, tiek savo vaikams. Ko gero, dažniau jie kliaujasi gerais atsiliepimais internete nei mokslinių tyrimų duomenimis ir gydytojų nurodymais.

VIRTUAL ELEMENT APPROXIMATIONS FOR TWO SPECIES MODEL OF THE ADVECTION-DIFFUSION-REACTION IN POROELASTIC MEDIA
Authors: Verma Nitesh , Kumar Sarvesh
Published: November 2022

This paper proposes virtual element methods for approximating the mathematical model consisting of coupled poroelastic and Advection-Diffusion-Reaction (ADR) equations. The space discretization relies on virtual element spaces containing piecewise linear polynomials as well as non-polynomials for displacement, pressure and concentrations, and piecewise constant for total pressure; a backwardEuler scheme is employed for the approximation of time derivative. Using standard techniques of explicit schemes, the well-posedness of the resultant fully discrete scheme is derived. Moreover, under certain regularity assumptions on the mesh, optimal apriori error estimates are established by introducing suitable projection operators. Several numerical experiments are presented to validate the theoretical convergence rate and exhibit the proposed scheme’s performance.
The Geometry of the G29-38 White Dwarf Dust Disk from Radiative Transfer Modeling
Authors: Ballering Nicholas P. , Levens Colette I. , Su Kate Y. L. , Cleeves L. Ilsedore
Published: November 2022

Many white dwarfs host disks of dust produced by disintegrating planetesimals and revealed by infrared excesses. The disk around G29-38 was the first to be discovered and is now well-observed, yet we lack a cohesive picture of its geometry and dust properties. Here we model the G29-38 disk for the first time using radiative transfer calculations that account for radial and vertical temperature and optical depth gradients. We arrive at a set of models that can match the available infrared measurements well, although they overpredict the width of the 10 μm silicate feature. The resulting set of models has a disk inner edge located at 92–100 R
WD (where R
WD is the white dwarf radius). This is farther from the star than inferred by previous modeling efforts due to the presence of a directly illuminated front edge to the disk. The radial width of the disk is narrow (≤10 R
WD); such a feature could be explained by inefficient spreading or the proximity of the tidal disruption radius to the sublimation radius. The models have a half-opening angle of ≥1.°4. Such structure would be in strong contradiction with the commonly employed flat-disk model analogous to the rings of Saturn, and in line with the vertical structure of main-sequence debris disks. Our results are consistent with the idea that disks are collisionally active and continuously fed with new material, rather than evolving passively after the disintegration of a single planetesimal.

Published: November 2022

In recent years, global coronal models have experienced an ongoing increase in popularity as tools for forecasting solar weather. Within the domain of up to 21.5 R
⊙, magnetohydrodynamics (MHD) is used to resolve the coronal structure using magnetograms as inputs at the solar surface. Ideally, these computations would be repeated with every update of the solar magnetogram so that they could be used in the ESA Modeling and Data Analysis Working Group magnetic connectivity tool (http://connect-tool.irap.omp.eu/). Thus, it is crucial that these results are both accurate and efficient. While much work has been published showing the results of these models in comparison with observations, not much of it discusses the intricate numerical adjustments required to achieve these results. These range from the details of boundary condition formulations to adjustments as large as enforcing parallelism between the magnetic field and velocity. By omitting the electric field in ideal MHD, the description of the physics can be insufficient and may lead to excessive diffusion and incorrect profiles. We formulate inner boundary conditions that, along with other techniques, reduce artificial electric field generation. Moreover, we investigate how different outer boundary condition formulations and grid design affect the results and convergence, with special focus on the density and radial component of the
B
-field. The significant improvement in accuracy of real magnetic map–driven simulations is illustrated for an example of the 2008 eclipse.
High-resolution Hubble Space Telescope Imaging Survey of Local Star-forming Galaxies. I. Spatially Resolved Obscured Star Formation with Hα and Paschen-β Recombination Lines

Published: November 2022

We present a sample of 24 local star-forming galaxies observed with broadband and narrowband photometry from the Hubble Space Telescope (HST) that are part of the Great Observatories All-sky Luminous Infrared Galaxies Survey of local luminous and ultraluminous infrared galaxies. With narrowband filters around the emission lines Hα (and [N ii]) and Paβ, we obtain robust estimates of the dust attenuation affecting the gas in each galaxy, probing higher attenuation than can be traced by the optical Balmer decrement Hα/Hβ alone by a factor of >1 mag. We also infer the dust attenuation toward the stars via a spatially resolved spectral energy distribution fitting procedure that uses all available HST imaging filters. We use various indicators to obtain the star formation rate (SFR) per spatial bin and find that Paβ traces star-forming regions where the Hα and the optical stellar continuum are heavily obscured. The dust-corrected Paβ SFR recovers the 24 μm inferred SFR with a ratio of −0.14 ± 0.32 dex and the SFR inferred from the 8 to 1000 μm infrared luminosity at −0.04 ± 0.23 dex. Both in a spatially resolved and integrated sense, rest-frame near-infrared recombination lines can paint a more comprehensive picture of star formation across cosmic time, particularly with upcoming JWST observations of Paschen-series line emission in galaxies as early as the epoch of reionization.
Miranda's Thick Regolith Indicates a Major Mantling Event from an Unknown Source
Authors: Beddingfield Chloe B. , Cartwright Richard J.
Published: November 2022

We investigated “muted” craters and scarps across Miranda’s cratered terrain. The morphologies of the muted craters are most consistent with modification by regolith deposition instead of erosion or viscous relaxation. We used three techniques to estimate regolith thickness. (1) Analysis of muted crater depth–Diameter (d-D) ratios near the South Polar Terrain Chasma indicates that regolith mantling their floors ranges from 0.3 to 1.2 km thick. Because older craters may have collected more regolith than younger craters, the true thickness may be similar to the highest estimate. (2) Analysis of crater size–frequency distributions across the cratered terrain indicates a thickness of 1.0 ± 0.2 km. (3) Analysis of a central mound within Alonso Crater indicates a thickness of

km near Verona Rupes and may represent an upper limit. These results indicate that Miranda has one of the thickest regoliths in the solar system, which has important implications for Miranda’s interior thermal properties. Regolith appears to mantle some scarps within Arden but not Elsinore or Inverness, indicating that Arden may be the oldest corona, contrary to previous relative age estimates. In this scenario, the mantling event was ongoing during Arden’s formation but before Elsinore or Inverness formed. We propose three possible sources for Miranda’s thick regolith: (1) giant impact ejecta, (2) plume deposits, and (3) Uranian ring deposits. We favor the ring deposit hypothesis, which is consistent with the regolith’s large spatial extent, substantial thickness, and Miranda’s slightly spectrally blue color. Follow-up studies that rigorously investigate these scenarios are required.
Eyes on the aliens: citizen science contributes to research, policy and management of biological invasions in Europe

Invasive alien species (IAS) are a key driver of global biodiversity loss. Reducing their spread and impact is a target of the Sustainable Development Goals (SDG target 15.8) and of the EU IAS Regulation 1143/2014. The use of citizen science offers various benefits to alien species’ decision-making and to society, since public participation in research and management boosts awareness, engagement and scientific literacy and can reduce conflict in IAS management. We report the results of a survey on alien species citizen science initiatives within the framework of the European Cooperation in Science and Technology (COST) Action Alien-CSI. We gathered metadata on 103 initiatives across 41 countries, excluding general biodiversity reporting portals, spanning from 2005 to 2020, offering the most comprehensive account of alien species citizen science initiatives on the continent to date. We retrieved information on project scope, policy relevance, engagement methods, data capture, data quality and data management, methods and technologies applied and performance indicators such as the number of records coming from projects, the numbers of participants and publications. The 103 initiatives were unevenly distributed geographically, with countries with a tradition of citizen science showing more active projects. The majority of projects were contributory and were run at a national scale, targeting the general public, alien plants and insects, and terrestrial ecosystems. These factors of project scope were consistent between geographic regions. Most projects focused on collecting species presence or abundance data, aiming to map presence and spread. As 75% of the initiatives specifically collected data on IAS of Union Concern, citizen science in Europe is of policy relevance. Despite this, only half of the projects indicated sustainable funding. Nearly all projects had validation in place to verify species identifications. Strikingly, only about one third of the projects shared their data with open data repositories such as the Global Biodiversity Information Facility or the European Alien Species Information Network. Moreover, many did not adhere to the principles of FAIR data management. Finally, certain factors of engagement, feedback and support, had significant impacts on project performance, with the provision of a map with sightings being especially beneficial. Based on this dataset, we offer suggestions to strengthen the network of IAS citizen science projects and to foster knowledge exchange among citizens, scientists, managers, policy-makers, local authorities, and other stakeholders.

PURPOSE:

To investigate changes in corneal curvature in different zones of the posterior corneal surface during a 6-month follow-up period after transepithelial photorefractive keratectomy (tPRK), femtosecond laser–assisted excimer laser in situ keratomileusis (FS-LASIK), and small incision lenticule extraction (SMILE).

METHODS:

The study included a total of 202 eyes, including 65, 77, and 60 that underwent tPRK, FS-LASIK, and SMILE, respectively. Elevation data for the posterior surface were obtained preoperatively (pre), as well as 1 week (pos1w), 1 month (pos1m), 3 months (pos3m), and 6 months (pos6m) postoperatively. Changes in posterior corneal curvature (M) were analyzed in the central (diameter: 0 to 3 mm), paracentral (diameter: 3 to 6 mm), and peripheral (diameter: 6 to 9 mm) regions.

RESULTS:

Over all follow-up periods, the central region of the posterior surface in all patients became flatter (
P
< .05), with FS-LASIK showing the largest change, whereas the paracentral and peripheral regions became steeper. The posterior curvature changes between pre and pos6m, determined before and after correction for ablated stromal depth, tended to follow similar trends in the three regions and after the three surgeries. There was also no significant correlation (

> .05) between the changes in the mean curvature (M, recorded between pre and pos6m) and each of the refractive error corrections, the changes in spherical aberration postoperatively, the optical zone diameter, ablated stromal depth, and residual stromal bed thickness in the central and peripheral regions, but the correlation was significant in the paracentral region.

CONCLUSIONS:

The postoperative changes in posterior corneal shape followed different trends in the central, paracentral, and peripheral regions. The FS-LASIK group exhibited the most notable changes in posterior corneal curvature, especially in the central region. These changes were statistically correlated with variations in spherical aberration, and ablated and residential stromal thickness in the paracentral region.

The Japanese Ministry of Health, Labour and Welfare compiled an Excel sheet — “Simple simulator for calculating nutritional food stocks in preparation for large-scale disasters” (Simulator). We examined the level of recognition and use of the Simulator by local governments and identified the points for its improvement. In stage 1, we surveyed local government personnel who participated in the “Workshop for nutrition assistance during large-scale disasters” held in November 2020 (n = 458; 313 responded) with an online questionnaire on the use of the Simulator and associated issues. Stage 2 involved group interviews with 15 public health dietitians who had been involved in food assistance during past natural disasters to identify points for improving the Simulator and the problems with food assistance during natural disasters. In stage 1, 233 responders (74.4%) confirmed their awareness of the existence of the Simulator. While 85 individuals (36.6%) used the Simulator, 63 individuals (74.1%) confirmed that they would use it in the future to plan and evaluate local government stocks. In stage 2, multiple comments regarding the Simulator's applicability and improvement in a realistic situation were collected. In order for the administrative staff in charge of disaster management to understand the nutritional importance of stockpiling main/side dishes, it was suggested that specific combinations of foods that meet the required amounts should be shown and that visualization using food products and the number of people covered by stockpiled foods may be easier to understand than pure nutritional values.
¿Materia lésbica?
Authors: flores val
Published: November 2022

Un ensayo que fabula un diálogo freático como experimentación teórica acerca de una (im)probable materia lésbica que se hace en los umbrales de las prácticas, cuerpos y territorios. A partir de una pregunta incómoda e impertinente, se despliega una ficción especulativa acerca de los modos normalizados de hacer teoría en la academia y sus interrupciones fugitivas. Una pregunta para ampliar nuestra piel al arrojarnos a pensar cómo llegamos a habitar los protocolos del saber institucional. Una práctica de escritura que tensa la intimidad y el erotismo, buscando más que definir la materia lésbica, vivir su erótica del (no) saber. Como un estado lésbico de la materia que es brújula sensible en las desorientaciones del pensar, para adentrarnos en el intento de desactivar la economía libidinal de la teoría dualista que separa teoría-práctica, teoría-cuerpo, teoría-territorio, y tantear las esquirlas visionarias de una pregunta atrapada en el tiempo de una conversación fabulada.

Due to the impact of the COVID-19 pandemic on the education systems, it becomes important to understand and analyze the perception of e-learning management systems. One essential learning management system (LMS) is Moodle. It is being recently implemented at the University of Warith Al-Anbiyaa (UOWA), Iraq and integrated with Google Meet to serve as a complete e-learning environment. This chapter uses technology acceptance model (TAM) to help the university decision-makers in predicting the behavioural intention to use Moodle. The core TAM model and other external variables like perceived enjoyment and perceived self-efficacy were examined. A quantitative research approach was implemented to perform the survey with a questionnaire to obtain the required data from 164 lecturers at the university. The data analysis processes reveal that lecturers see Moodle as easy to use and enjoyable, and they are able to master its capability easily. The obtained results have confirmed the TAM model's importance in understanding and predicting the acceptance of Moodle by UOWA lecturers.
Screencasts as Job Aids and the Basis of a Faculty Training Course
Authors: Jesus Rui Alberto
Published: November 2022

Educational institutions are becoming increasingly digital. To keep up with this trend, their employees must develop ICT skills to fully perform their functions in this digital era. However, face-to-face training is very time-consuming and difficult to implement, especially in geographically dispersed organizations. An asynchronous training course based on short videos can be the ideal solution to this problem. In addition, these training videos can also be used as job aids, after the accredited course is over. In this chapter, the author describes the skills that faculty should have in the digital era and how a set of well-designed training videos can be the solution to bring together the advantages of two major areas: training faculty and job aids. A case study in a Portuguese university of health sciences is also presented, where this solution brought several productivity gains.
Factors Affecting Cloud ERP Adoption by Tunisian SMEs
Authors: Haddar Houneida , Bouaziz Fatma
Published: November 2022

This study aims to identify the factors that determine the intention to adopt cloud ERP by Tunisian small, medium, and micro-enterprises (SMEs). Based on previous studies on cloud computing and cloud ERP, a research model was developed. A questionnaire survey was administrated online with two samples of adopters and non-adopters of traditional ERP during the first wave of the COVID-19 pandemic in Tunisia. Collected data were analyzed through PLS-SEM techniques. Findings suggest that both compatibility and technological readiness are favoring the cloud ERP adoption by SMEs adopters of traditional ERP, whereas compatibility and managers' support are driving its adoption by SMEs, non-adopters of these systems. Relative advantage, complexity, data security and confidentiality, financial readiness, regulatory support, and competitive pressure are insignificant factors for the two samples. This research contributes to fill some of the highlighted theoretical gaps in the field and may help managers and ICT staff in SMEs, cloud ERP providers, and policy makers to make more informed decisions.

An individual approach to learning is very important for students with disabilities. Teaching based on games enables certain educational content to be introduced to students in a suitable and understandable way. The aim of this paper is to identify important characteristics digital educational games should have to be playable by students with intellectual disabilities. The key characteristics will facilitate special education teachers' selection of digital educational games that their students can play which will enhance the teaching process and enable students with intellectual disabilities to acquire academic and socio-emotional skills necessary to function in everyday life. The research was conducted in two phases. The first phase included a review of the literature that identified 13 characteristics. The second phase of the research was a survey with special education teachers that provided leveling for eight characteristics and defined nine additional characteristics without leveling by which one can assess whether a game can be played by a student with intellectual disabilities.

EN-9 is one of the steel grades, and it is widely used in power plants, automobiles, and the aerospace sector. The availability and ductility of EN9 steel have been limited. Heat-treatment procedures are used to increase the hardness, wear resistance, and percentage of elongation. The main intention of this study is to discover the effect of heat treatment on EN8 steel. In this work, the various kinds of heat-treatment methods like annealing, normalizing, hardening, and tempering were carried out on EN-8 steel. Mechanical properties like hardness, tensile strength, and percentage of elongation are evaluated. The microstructure is examined and compared, before and after the heat treatment process. Hardening and tempering results indicated that EN8 steel has better hardness, yield strength, ultimate tensile strength and elongation when compared to EN9 steel.
Wireless Power Transfer With Inductive Coupling for EVs
Authors: Jog Pranjal , Kumawat R. K.
Published: November 2022

Electric vehicles (EVs) are expected to replace the fuel-based vehicles on the road that are polluting the environment soon. Wireless charging is based on a concept that was developed 30 years ago, which works on inductive power transmission. EVs of all classes and power levels may presently be charged from a single ground source using wireless charging systems, which are efficient and adaptable. The entire system can be automated by utilizing wireless power transfer (WPT) technology. Designing a new mathematical expression that can be utilized to determine a charging system's efficiency is the main goal of the current effort. Then the physical variables and efficiency parameters involved in the WPT system are optimally tuned by a revamped Harris Hawks Optimization Algorithm, which is a conceptual improvement of the Harris Hawks Optimization (HHO) algorithm. Finally, an experimental investigation is carried out to prove the fact that proposed algorithm is capable of solving the test functions with greater accuracy and improved efficiency.
An Improved Sparrow Approach
Authors: Chen Wenfang
Published: November 2022

The basic sparrow search algorithm reduces the population diversity at the later stage of the iteration and is easy to fall into local extremes. An improved sparrow algorithm (ISSA) is proposed basen on fusion of Cauchy mutation and reverse learning. Firstly, a Sin chaotic initialization population with unlimited number of mapping folds is used to lay the foundation for global optimization. Secondly, the previous generation global optimal solution in the discoverer position update method is introduced to improve the sufficiency of the global search, and at the same time, adaptive weights are added, local mining and global exploration capabilities are coordinated to speed up the convergence speed; then, the Cauchy mutation operator and the reverse learning strategy are combined to perform perturbation mutation at the optimal solution position, new solutions are generated, the algorithm's ability is enhanced to jump out of local space. Finally, the paper compared with three basic algorithms and two improved sparrow algorithms.

A Strong ECC Based on Secure Authentication with Privacy for IoT Concepts
Authors: Abderrezzak Sebbah , Benamar Kadri
Published: November 2022

The internet of things offers a rich set of options and applications in different fields, such as smart home, agriculture, security, transportation, and health issues. The IoT aims at organizing the interactions between items that are both sensors and actuators, known as objects. These objects acquire new applications in our lives that facilitate the remote control of smart devices via the open channel. However, this makes the sensitive transmitted data easily reachable and vulnerable to many attacks. With this in mind, security and privacy become an essential requirement that precedes the deployment of any IoT network. In this paper, the authors provide an IoT authentication and key agreement scheme using ECC and a fuzzy extractor and then they use BAN logic model and AVISPA tool to demonstrate the security of the scheme. They show that the proposed scheme is resistant to various attacks. Furthermore, the security analysis of the proposed scheme and its comparison with some other related works have shown that the proposed scheme is both more efficient and more secure than the other ones.
