Overlapping grid SQLM for third-grade modified nanofluid flow deformed by porous stretchable/shrinkable Riga plate
Authors: Mkhatshwa Musawenkhosi Patson , Khumalo Melusi
Published: February 2023

The improvement in thermal performance of fluid and the control of energy loss are equitably significant. Therefore, the purpose of this study is to analyze entropy generation, stagnation point flow, and thermal characteristics of non-Newtonian third-grade modified hybrid nanofluid generated by a stretchable/shrinkable Riga plate in a porous medium with varying flow viscosity. In this analysis, a modification of hybrid nanofluid is considered by using pure water as a base fluid and three various nanomaterials (aluminium oxide, copper, and nickel) as nanoparticles in the characterization of heat transfer. Furthermore, the contribution of heat source/sink and viscous dissipation are accounted for in the model. The suited transformations are enforced to remodel the governing mathematical equations to produce ordinary differential equations that are conveniently tackled via spectral quasilinearization method (SQLM) along with the overlapping grid idea to yield numerical solutions. The preference of this approach over others has been justified through discussion of error bound theorems, residual and solution errors, computational time, and conditioning of matrices. The physical significance of disparate governing parameters on flow variables, velocity gradient, thermal rate, and entropy generation are scrutinized through graphs and tables. Crucial findings of the study include that temperature of the modified hybrid nanofluid enhances quickly (better thermal conductor) than temperature of single nanofluid, hybrid nanofluid, and conventional third-grade fluid for higher Biot number, variable viscosity, and heat source parameters. Mass suction enhances fluid flow and physical quantities of interest, but suppresses the fluid temperature. An increase in variable fluid viscosity, modified Hartmann number, and third-grade parameters enhances the wall drag coefficient while lowering the rate of heat transfer, and the opposite is true for porous media. More entropy is generated in the system by high variable fluid viscosity, suction, viscous dissipation, modified Hartman number, and non-Newtonian parameters. Owing to high velocity and temperature associated with modified hybrid nanoparticles, modified hybrid technology is recommended in enhancing the physical attributes of the fluid with minimal cost effects. In engineering and industrial point of view, this study can contribute significantly in thermal improvement of the working fluid.

Published: February 2023

As the primary method of communicating research results, journals garner an enormous impact on community behavior. Publishing the underlying research data alongside journal articles is widely considered good scientific practice. Ideally, journals and their publishers place these recommendations or requirements in their author guidelines and data policies. Several efforts are working to improve the infrastructure, processes, and uptake of research data sharing, including the NFDI4Chem consortium, working groups within the RDA, and IUPAC, including the WorldFAIR Chemistry project. In this article, we present the results of a large-scale analysis of author guidelines from several publishers and journals active in chemistry research, showing how well the publishing landscape supports different criteria and where there is room for improvement. While the requirement for deposition of X-ray diffraction data is commonplace, guidelines rarely mention machine-readable chemical structures and metadata/minimum information standards. Further evaluation criteria included recommendations on persistent identifiers, data availability statements, data deposition into repositories as well as of open analytical data formats. Our survey shows that publishers and journals are starting to include aspects of research data in their guidelines. We as authors should accept and embrace the guidelines with increasing requirements for data availability, data interoperability, and re-usability to improve chemistry research.

Das vereinsrechtliche Verbot und die Auflösung von Gesellschaften durch Verwaltungsbehörden haben bislang wenig Aufmerksamkeit gefunden. Aufgrund des russischen Angriffskrieges in der Ukraine könnte sich dies ändern. Das Bundesinnenministerium hat mehrere Vereinigungen wegen der Finanzierung sich gegen den Gedanken der Völkerverständigung richtender Organisationen verboten, zuletzt auch eine GmbH. Liegt in der Finanzierung eines Angriffskrieges eine sich gegen den Gedanken der Völkerverständigung richtende Tätigkeit, wären insbesondere mit dem Aggressor verbundene Kapitalgesellschaften zu verbieten bzw. aufzulösen, es stellt sich aber auch die Frage eines Ermessens der Behörden. Leisten Unternehmen Zahlungen, die einen Angriffskrieg finanzieren, ist dies auch gesellschaftsrechtlich von Belang. Einzugehen ist neben der Auflösung auf die Pflichten der Geschäftsleiter, aber auch die Rolle von Kontroll- und Gesellschafterorganen.
Spatial Distribution of Corrosion Products Influenced by the Initial Defects and Corrosion-Induced Cracking of the Concrete
Authors: Zhu Wenjun , Yu Zhongxu , Yang Chengyue , Dong Fei , Ren Zengle , Zhang Kai
Published: February 2023

This paper studies the spatial distribution of the corrosion products in concrete based on a series of experimental investigations of a marine construction. The distributions of defects and corrosion products in the concrete cover were identified in a mesoscale based on the computed tomography test, and the fractal dimension of cracks was analyzed. Some cracks and defects were filled by corrosion products in various degrees. The results showed that the defects were significantly influenced by the shape and relative location of the deformed steel reinforcement, which would then lead to the variation of the corrosion layer. The migration of corrosion products was particularly affected by the location and geometry of the defects, which could provide a suitable channel for the migration of corrosion products. The research can be helpful for the prediction of concrete cracking performance induced by the chloride-induced corrosion of the steel reinforcement.

Authors: Ghosh Anik , Kulkarni Rishikesh , Gupt Chandra Bhanu , Sekharan Sreedeep
Published: February 2023

We propose the use of a lensless digital in-line holography setup for the measurement of particle size distribution (PSD) of fly ash obtained from wet electrostatic precipitators of different power plants. The fly ash samples were prepared by spreading the ash nonuniformly over a glass slide. A number of holograms corresponding to distinct regions of the glass slide were recorded and reconstructed. The particle sizes in each reconstructed image were estimated using a circular Hough transform–based edge detection algorithm. PSDs in the range of 10 to 90 μm were obtained. A numerical scheme to extend the measurement range below 10 μm is discussed. The performance of the proposed method is compared with the laser particle-size analyzer and conventional hydrometer. The experimental results indicate that the performance of the proposed method is similar to the hydrometer, with lower experimental and time complexity.

Organoids are three-dimensional cell accusations generated from pluripotent stem cells or adult stem cells in vitro. With many advantages over cell and animal models, organoids have been increasingly used in drug and clinical medical research in recent years. Chinese herbal medicine (CHM) is characterized by multi-target and multi-pathway treatment methods; however, there is no commonly accepted study method regarding efficacy and underlying mechanisms. In this review we summarized the important applications of organoid models in pharmacodynamic mechanism studies, efficacy and safety evaluations, and CHM personalized medicine, thus providing the theoretical basis for its development and innovation.
Prespecification of Structure for the Optimization of Data Collection and Analysis
Authors: Vowels Matthew J.
Published: February 2023

Data collection and research methodology represents a critical part of the research pipeline. On the one hand, it is important that we collect data in a way that maximises the validity of what we are measuring, which may involve the use of long scales with many items. On the other hand, collecting a large number of items across multiple scales results in participant fatigue, and expensive and time consuming data collection. It is therefore important that we use the available resources optimally. In this work, we consider how the representation of a theory as a causal/structural model can help us to streamline data collection and analysis procedures by not wasting time collecting data for variables which are not causally critical for answering the research question. This not only saves time and enables us to redirect resources to attend to other variables which are more important, but also increases research transparency and the reliability of theory testing. To achieve this, we leverage structural models and the Markov conditional independency structures implicit in these models, to identify the substructures which are critical for a particular research question. To demonstrate the benefits of this streamlining we review the relevant concepts and present a number of didactic examples, including a real-world example.

Investigating the properties of semiconductor nanomaterials to understand the specific behavior of nano-scale materials and predicts novel advancement of functionalized semiconductor materials that are influenced by cohesive energy. Cohesive energy is strongly associated with semiconductor nanomaterials as the energy increment by the arrangement of atoms in a crystal which is one of the most fundamental properties. In this communication, the shape and size dependence over the energy bandgap of copper chalcogenide semiconductor nanomaterials is investigated. The theoretical model is derived on cohesive energy of semiconductor nanomaterials was equated with the bulk materials. For this research, we considered Cu2SnS3, Cu2SnSe3, Cu2SnTe3, Cu3SbSe4, and CuSbS2 chalcogenide matters to the study of shape and size dependent-energy bandgap. The model forecasts that the energy bandgap is inversely proportional to the size of the semiconductor. The present modeling results are correlated with established experimental data and underpin the model reported.

In this work, the electronic, magnetic and optical features of the diluted magnetic semiconductors (DMS) Cd1-xFexS (x= 6.25%, 12.5%, 25%) are determined by density functional theory (DFT). The analysis of electronic BS and magnetic moment of Cd1-xFexS show a half metallic ferromagnetic (HMF) nature with direct energy gap (Eg).The Egof CdS is elevated by incrementing the doping concentration of iron atoms. Moreover, the replacement of Cd with Fe turns CdS into an-type semiconductor. The effect of Fe concentration on the optical parameters such as absorption coefficient, refractive index, dielectric function, optical conductivity, and reflectivity is also investigated. Results revealed that Cd1-xFexS is a suitable compound for spintronicsand optoelectronics devices.

Using chemical bath deposition in an ammonia-free system, CdS/PbS solar cells have been synthesized with different Al content in their composition and varying its absorber layer thickness. Nanocrystalline CdS thin-films with an average thickness of 140 nm were prepared and, subsequently, PbS thin-films with two different thicknesses (330 and 790 nm) were grown on the CdS. X-ray diffraction studies shows that CdS and PbS thin films have a hexagonal and cubic structure, respectively. The illuminated current/voltage characteristic curves of these p-n junctions were measured using a 300 W solar simulator at air mass 1.5, and a frequency of 50-60 Hz. It was found that Al doping decreases the conversion efficiency of the solar cells with the thinnest absorber layer, from 0.19 % to 0.05 %, and for those with thicker layers, from 0.19 % to 0.03 %.

The current work focused on enhancing solar cell’s Power Conversion Efficiency (PCE) while using zinc sulphide (ZnS) material as Anti-Reflective Coating (ARC). The ZnS layers were deposited over the solar cell surface by RF sputtering technique. The coating was performed in argon gas atmosphere with sputtering time such as 10, 20, 30 & 40 min represented as S-I, S-II, S-III and S-IV respectively. The power conversion efficiency of ZnS coating on polycrystalline silicon solar cells was studied by evaluating optical properties, electrical characteristics, structure morphology and temperature study. It is observed that the S-III coating exhibits optimum hall mobility (µ),improved carrier concentration (N) and electrical resistivity (ρ) and the measured values are 12.88 cm2V -1 s - 1 , 3.98×10-3 Ω-cm and 21.88×1020 cm-3 respectively. The maximum PCE of 17.39% and 19.12% are obtained for S-III coating at open source condition and controlled source condition respectively. The effect of operating temperature on ZnS coated solar cells at both open source and controlled source condition is also investigated. The results revealed that the ZnS can be reliable ARC for improving the power conversion efficiency of solar cells.
GH-dependent growth of experimentally induced carcinomas in vivo
Authors: Marker Paul C , Unterberger Christopher J , Swanson Steven M
Published: February 2023

Interest in investigating the role of the growth hormone (GH)/insulin-like growth factor 1 (IGF-1) axis in the initiation and progression of experimentally induced carcinomas has arisen due to several observations in the human population. First, subjects with Laron syndrome who lack GH signaling have significantly lower rates of cancer than people who have normal GH signaling. Second, epidemiologic studies have found strong associations between elevated circulating IGF-1 and the incidence of several common cancers. Third, women who bear children early in life have a dramatically reduced risk of developing breast cancer, which may be due to differences in hormone levels including GH. These observations have motivated multiple studies that have experimentally altered activity of the GH/IGF-1 axis in the context of experimental carcinoma models in mice and rats. Most of these studies have utilized carcinoma models for four organ systems that are also frequent sites of carcinomas in humans: the mammary gland, prostate gland, liver, and colon. This review focuses on these studies and describes some of the most common genetic models used to alter the activity of the GH/IGF-1 axis in experimentally induced carcinomas. A recurring theme that emerges from these studies is that manipulations that reduce the activity of GH or mediators of GH action also inhibit carcinogenesis in multiple model systems.

Published: February 2023

Objective

This study evaluated the efficacy of antithyroid drugs (ATDs) and risk factors associated with the recurrence of Graves’ hyperthyroidism using a comprehensive retrospective cohort.

Methods

We included 1829 patients newly diagnosed with Graves’ hyperthyroidism, with sufficient follow-up data. Clinical outcomes of the patients and risk factors associated with recurrence-free survival, including the changes in thyrotropin receptor antibody, were evaluated.

Results

The median age of the patients was 44.5 years, and 69% were female. Among the patients, 1235 had a chance to withdraw ATD after a median of 23 (interquartile range (IQR) 17.0–35.5) months of treatment. The first remission rate was 55.6% during a median of 72.7 months of follow-up. After the first recurrence, 95% of patients underwent the second course of ATD treatment for a median of 21.1 (IQR 14.8–31.7) months, and the remission rate was 54.1%. During a median of 67 months of follow-up, 7.7% of patients underwent surgery, and 10.5% underwent radioactive iodine therapy. Approximately 30% were still on ATD therapy for recurrent disease or prolonged low-dose maintenance. Younger age (<45 years), male sex, and fluctuating or smoldering of TRAb levels were independent risk factors of the first recurrence after ATD treatment.

Conclusions

ATD treatment is an acceptable option for the initial treatment of Graves’ hyperthyroidism as well as for recurrent disease. The optimal treatment period for ATD treatment needs to be determined using the individual risk factors of recurrence.
No centenario de "Alén", de Xaime Quintanilla. Unha estimación crítica
Authors: Vieites Manuel Francisco
Published: February 2023

En 2021 pasou, case inadvertido, o centenario da publicación de Alén, de Xaime Quintanilla, peza fundamental na renovación da literatura dramática galega anterior á Segunda República. A obra contiña unha proposta anovadora para unha escena aínda inzada dun rexionalismo cultural moi asentado no costumismo, e que, con espectáculos como A man de Santiña, quería iniciar a senda dun realismo enxebre. Neste artigo, escrito a partir dunha revisión de literatura, da perspectiva comparada que nos permite visitar outras autorías, pezas e teatros, e da esexese da obra coas ferramentas que ofrece a dramaturxia como disciplina para a ideación de espectáculos, consideramos as innovacións presentes no texto e no proxecto de escenificación que contén.
La narrativa de Miguel Ángel Hernández: un egorretrato literario
Authors: Orsini-Saillet Catherine
Published: February 2023

El presente artículo propone una lectura de las tres primeras novelas de Miguel Ángel Hernández (Murcia, 1977) ―Intento de escapada, 2013; El instante de peligro, 2015; El dolor de los demás, 2018― consideradas como «egorretratos literarios», es decir, como autorretratos trazados por un yo narrador autodiegético que no se confunde con el autor a pesar de las similitudes. Se analiza cómo se construyen las autofiguraciones de estos yoes que se convierten en las figuras centrales de los textos y se realza específicamente el papel de las imágenes y de la alteridad. Se recalca que los tres narradores son alter ego de un autor que, a través de ellos, se pone en escena, juega con sus máscaras para interrogar sus propias fragilidades e intentar resolverlas.

Gastroesophageal reflux disease (GERD) affects millions of people worldwide with significant clinical consequences [1, 2]. GERD presents with recurrent and severe heartburn and regurgitation or GERD-specific complications and affects approximately 20% of the adult population in high-income countries [3, 4, 5]. GERD has a worldwide prevalence of 8% to 33%, affects all age groups and both sexes [6, 7], and has a cost estimated at >$9-10 billion per year in the US alone, largely due to associated with using of proton pump inhibitors (PPIs) and diagnostic testing [8, 9]. GERD can affect patients’ health-related quality of life and associated with an increased risk of esophagitis, esophageal strictures, Barrett’s esophagus, and esophageal adenocarcinoma. Gastroesophageal reflux is primarily a disorder of the lower esophageal sphincter, but there are other factors that contribute to its development. The main symptoms of GERD are heartburn and regurgitation. However, GERD can present with a variety of other extraesophageal symptoms. Typical symptoms of GERD are often sufficient to establish the diagnosis, and such patients can be empirically prescribed a proton pump inhibitor. Endoscopy, esophageal manometry, and esophageal pH monitoring are recommended for patients who do not respond to such treatment or if the diagnosis is unclear. Lifestyle changes, medications, and surgery are the main treatment options for GERD.

Published: February 2023

Convolutional Neural Network (CNN) is an effective Deep Learning (DL) algorithm that solves various image identification problems. The use of CNN for time-series data analysis is emerging. CNN learns filters, representations of repeated patterns in the series, and uses them to forecast future values. The network performance may depend on hyperparameter settings. This study optimizes the CNN architecture based on hyperparameter tuning using Particle Swarm Optimization (PSO), PSO-CNN. The proposed method was evaluated using multivariate time-series data of electronic journal visitor datasets. The CNN equation in image and time-series problems is the input given to the model for processing numbers. The proposed method generated the lowest RMSE (1.386) with 178 neurons in the fully connected and 2 hidden layers. The experimental results show that the PSO-CNN generates an architecture with better performance than ordinary CNN.

Published: February 2023

Trauma is a problem of global public health with economic, social and political extensions. It is constantly growing due to road accidents. The cost of hospitalization and the loss of working hours for those who managed to reach the hospital are huge for the national economy of each country. The purpose of the present study is to record the polytrauma patients of road accidents and to search for their economic cost. A total of 68 injured people were the study sample during the period 2014-2017. The study was conducted in a University hospital in Athens (Greece). The mean age of the patients was 36.67 years. The mortality was 13.2% and the mean cost of every polytrauma patient was 14.272 Euros. Nearly half of them had an infection, which increased the cost. Accident prevention, proper and timely treatment of injuries, monitoring, recording and controlling infections and reducing the length of hospitalization are some of the ways to reduce the financial cost of a traumatized person.
Vortex-induced vibration analysis of submerged floating tunnel tension legs
Authors: Su Zhibin , Sun Shengnan , Lu Yushuo , Pan Yulong
Published: February 2023

Considering the influence of axial and transverse vibration of tension legs of submerged floating tunnel, the non-linear vibration equation of the tension leg under the action of vortex-induced excitation is derived and solved numerically by Galerkin and Runge–Kutta methods. The results show that the vibration amplitude and frequency of tension legs under the action of vortex-induced excitation are related to the natural frequency of tension legs. Due to water damping, the vortex-induced vibration response of tension legs in submerged floating tunnel is lower than that of the tension leg in air; the shorter the length of the tension leg, the higher will be the current velocity needed to produce vortex-induced resonance; the larger the initial tension of the tension leg, the faster will be the current velocity needed to generate vortex-induced resonance; the transverse pulse force increases with an increase of the initial tension and the outside diameter of the tension leg, and decreases with an increase of the length of the tension leg.

Published: February 2023

Depuis plusieurs années, la prévention et la promotion de la santé se trouvent au cœur des politiques de santé publique. Une pluralité d’interventions se déploient, amenant à une redéfinition des champs d’exercice et une évolution des pratiques professionnelles. Cette étude qualitative, réalisée auprès de professionnels, explore les pratiques, les savoirs et représentations mobilisés dans l’intervention en prévention et promotion de la santé et tend à repérer les processus sous-jacents à la circonscription de ces deux champs d’exercice. Les résultats montrent une difficulté à délimiter le « territoire » de la prévention et de la promotion de la santé. Les savoirs construits sont davantage caractérisés par une « mise en pratique » plutôt que fondés sur une conception théorique. Il existe une tension entre politiques publiques et valeurs professionnelles. Cette étude invite à réinterroger des notions essentielles (prévention et promotion de la santé) inhérentes à des champs d’exercice en santé publique. Enfin, ce travail met en perspective la manière dont les professionnels s’approprient et incarnent la prévention et promotion de la santé sur leur terrain d’exercice, réélaborent et transmettent des savoirs en ce sens. L’amélioration de la connaissance des pratiques et des représentations constitue une démarche heuristique de compréhension des réalités complexes de terrain.

L’extension du concept d’inclusion dans le champ de l’éducation, au-delà du domaine du handicap et des personnes à besoins spécifiques, s’est imposée dans le domaine de l’éducation interculturelle, en Europe, dans les années 2010. On se propose ici de décrire le rôle des grandes organisations internationales (Commission Européenne, Conseil de l’Europe, Unesco, OCDE…) dans la promotion de ce concept et des valeurs corrélées, et de repérer les indications concernant l’adaptation des personnels à ce nouvel environnement théorique.
On analyse ensuite, pour la France et pour l’Italie, la traduction dans des prescriptions, en direction des professionnels, par les autorités politiques centrales. Puis on restitue la réception de cette extension du champ de l’inclusion chez quelques chercheurs en éducation ainsi que l’orientation de leurs travaux sur ce processus.

The relationship between naturalized and native plant species: insights from oceanic islands of the south-east Pacific after 200 years of records. v1
Authors: Cáceres-Polgrossi Luis
Published: February 2023

We assembled the most comprehensive dataset of the flora of the OISEP from currently available island flora checklists and updated with recent publications. Each plant species was classified as being native or naturalized. We examined temporal changes by estimating species richness, naturalization rates and naturalized-to-native ratios over time based on the first collection year of each naturalized species. Then, we determined the best shape of naturalized species richness accumulation over time by contrasting the AIC of lineal, exponential, sigmoidal and Weibull regressions. Finally, we analyzed the relationships between native and naturalized species firstly at the inter-archipelagic scale by fitting island species-area relationship models and secondly at the island scale by performing ranged major axis regression analysis on residual values.

Regional and far-regional earthquake locations and source parameters using sparse broadband networks: A test on the Ridgecrest sequence
Authors: Dreger Douglas , Uhrhammer Robert , Pasyanos Michael , Franck Joseph , Romanowicz Barbara
Published: February 2023

Events of the 1995 Ridgecrest, California, earthquake sequence were located and source parameters were estimated using data recorded by the broadband, high-dynamic-range instrumentation of the Berkeley Digital Seismic Network (BDSN). The purpose of this study is to investigate the capability of a sparse broadband network at monitoring a region located outside of the network, as will be the case in the monitoring of the Comprehensive Test Ban Treaty (CTBT) for low-magnitude seismic events. In addition, we present a case study that is representative of the capabilities of other regional broadband networks. To assess the capability of a sparse network, we compared locations estimated from BDSN phase measurements to a “ground truth” catalog of high-quality earthquake locations derived from data recorded by the Southern California Seismic Network (SCSN). An adaptive grid search location program that utilizes the timing and azimuth of multiple-phase picks from one or more stations was used to determine the importance of the different types of data on absolute event locations. Sparse subnets of BDSN stations in the distance ranges from 250 to 500 km and 500 to 800 km were used. The results indicate that in the regional distance range, it is possible to obtain absolute event locations to within 18 km as is prescribed by the CTBT; however, in the far-regional distance range, the lower signal-to-noise levels precluded the location of the events to within the CTBT objective.
Study of weak and strong ground motion including nonlinearity from the Northridge, California, earthquake sequence

This article presents a new method to estimate S-wave site response relative to a regional layered crustal model. The method is useful for site-specific strong-motion prediction because the estimated site-response functions are referenced to an idealized regional layered model for which we know the ground response exactly. We applied this method to the Northridge earthquake sequence. We determined the site amplifications, from aftershocks with magnitudes 2.6 to 4.3, at 21 stations that were colocated with strong-motion stations. These site-response functions were then used to modify synthetic seismogram calculated for the Northridge mainshock in the same regional layered crustal model and thus obtain site-specific ground-motion estimates. These site-specific synthetic seismograms have higher correlation to observations in comparison to the synthetic seismograms without weak-motion site correction. They have similar amplitude and frequency content to the observations, especially at sites with recorded peak ground accelerations below 0.3 g. At sites with larger ground motions, however, this approach overestimates the strong motion. The differences are made clear when we estimate site-response functions from the strong-motion records and compare them with those from weak-motion records. We express the differences as the average ratio of the weak- to strong-motion site response (AWS ratio). When the ground motion is low, the AWS ratio is near unity, indicating that the weak- and strong-motion site responses agree with each other within the uncertainty. However, the AWS ratio increases as the ground-motion amplitude increses. The difference in weak- and strong-motion site responses becomes significant at stations where peak acceleration was above 0.3 g, peak velocity was above 20 cm/sec, or peak strain was above 0.06% during the mainshock. This result demonstrates directly from the ground-motion observations the relationship between nonlinear site response and peak ground-motion parameters. The nonlinearity is present on soft rock sites as well as on sediment sites.
Dynamics of thrust faulting: 2D lattice model

Particle motions in a foam rubber model of shallow-angle thrust faulting show many features different from those commonly assumed in dislocation models of subduction thrusts (Brune, 1996). As a complement to a physical foam rubber experiment, we have carried out dynamic simulation using a 2D lattice numerical model. The model is constructed as a triangular block sliding over a rectangular elastic block. It consists of a 2D set of particles interacting with each other by nonlinear Hooke's forces and obeying Newton's equations of motion. Rough surfaces are introduced on the contact plane of the two blocks to simulate realistic friction.

The numerical simulations demonstrate several key features of thrust faulting, including stick slip, fault opening, and strong breakout and shaking at the hanging-wall toe (the wedge-shaped tip of the outcropping hanging-wall block) of the thrust fault, all consistent with the foam rubber experiments. The stick-slip motion shows an approximate time and slip repeatable behavior. Each slip event is characterized by a self-healing pulse associated with fault opening and frictional locking. The rupture pulse propagates steadily along the fault. When rupture reaches the toe of the fault outcrop, the hanging wall breaks away from the foot wall and creates a large opening vibration of the hanging wall. The peak acceleration observed at the hanging-wall toe of the fault outcrop is about 3 to 4 times the peak acceleration in the center part of the fault, and about 2 to 3 times the motion of the foot wall. Such a large increase in peak acceleration at the toe is caused mainly by multiply reflecting stress waves trapped in the wedge-shaped hanging wall of the fault. The strong asymmetry of the particle velocity between the hanging wall and foot wall is an important feature of the results consistent with the foam rubber model but different from standard dislocation models. This dynamic result illustrates the important effects of thrust faulting geometry on fault slip and ground motion.
Modeling of crustal layering using three-dimensional analysis of stress-drop slip zones in an elastic layer/half-space system

Published: February 2023

A numerical scheme for calculating the elastic fields in a layer over a half-space medium due to embedded slip zones of prescribed stress drop was developed to examine how the layer influences fault mechanics. Although the method is general, for simplicity, only penny-shaped slip zones were considered in the current analysis. For slip zones that are embedded in the half-space and near the interface, it was found that the layer causes the slip to depart from that for a uniform medium: softer layers tend to increase, but stiffer layers tend to decrease the magnitude and gradient of the slip near the upper end of a slip zone. Consequently, the layer causes an increase, if the layer is softer, or a decrease, if the layer is stiffer, in the energy release rate of the slip zone. The layer was also seen to have a strong effect on the surface displacements to the extent that the distance change predicted between a pair of stations across the slip zone could be biased by a uniform half-space model. The results also showed that the layer can cause a significant change in the uniform normal stress, which can alter the frictional resistance.
