Corporate Social Responsibility Disclosure (CSRD) and Financial Distressed Risk (FDR): Does Institutional Ownership Matter?
Authors: Tarighi Hossein , Appolloni Andrea , Shirzad Ali , Azad Abdullah
Published: January 2022

This study aims to investigate the effect of corporate social responsibility disclosure (CSRD) on financial distressed risk (FDR) among firms listed on the Tehran Stock Exchange (TSE). This paper also examines whether there is a negative linkage between institutional ownership as a corporate governance mechanism and corporate bankruptcy. The final research purpose is to analyze if there is a moderating effect of institutional owners on the relationship between CSRD and FDR too. The study sample consists of 200 firms listed on the TSE between 2013 and 2018, and the statistical model is logistic regression. When FDR is assessed under both Article 141 of Iran’s business law and the Altman Z-score model, our results on the main research hypotheses are quite similar. Considering the social and cultural conditions and economic situation of the Iranian market, the results show that firms with a high level of CSR disclosure are not able to make themselves more creditworthy and do not have better access to financing, resulting in more financial insolvency. Our findings confirm institutional shareholders play a vital role in facilitating a firm’s emergence from bankruptcy. The results also demonstrate financial distress risk is less seen among companies with more institutional owners that disclose more CSR information. In other words, since the goals related to CSR are long-term and Iranian institutional investors have a long-term horizon towards the company, the presence of more institutional owners within a firm push managers to provide additional voluntary CSR disclosure so firms can maintain the trust of their shareholders at the highest possible level and prevent financial distress. Our additional analysis indicates there is a positive association between financial leverage and firm failure, whereas the current ratio and ROA are negatively connected with corporate bankruptcy. Finally, when FDR is assessed on the Altman Z-score model, our evidence supports a negative relation between purchase and sale-related party transactions and bankruptcy risk, which is consistent with the efficient transaction hypothesis.

Published: January 2022

Coffee cultivation is one of the main agricultural activities in Colombia, which increases the well-being of coffee-growing families. In order to determine the impact of coffee production, the capital endowment and well-being of coffee-growing families in the municipality of Pitalito, in the south of Colombia, were analyzed using the community capital index (CCI). Likewise, the relationships between the variables were identified through a Pearson correlation analysis, and the increase in well-being was identified and modeled by employing structural equations. The structural equation model showed a suitable fit to the data, indicated by the non-significant value of the χ2 statistic (p = 0.85), a high CFI (0.97), a low RMSEA (<0.001), a low stability index (0.23) and a low variance inflation factor (VIF = 1.42). At the capital level, political capital in synergy with social capital increased the well-being of coffee-growing families; meanwhile, capitals such as natural and physical-built capital did not have the greatest impact on well-being. Political capital variables such as the “possession of the coffee identification card” (CPI), as well as the variable “participates in the activities carried out by the community action board of the village” (PAC), increased by 9.9% and 8.66%, respectively, in the well-being of coffee-growing families measured by the CCI. The social capital variables that boosted the CCI were the benefits of the National Federation of Coffee Growers (FNC) (BFN, %V(variation): 8.32) and associativity (Aso, %V: 7.51). Other variables that make up human capital with high incidence in the CCI were family size (FSi) and the number of people who can read in the family (FLE) with a variation of 9.12% and 8.6%, respectively. However, other variables such as labor cost for disease management (CDM) and labor cost for harvesting (HCL) had no significant effect on the variation of the CCI. It was found that the level of well-being increases due to variables such as associativity and participation in grassroots organizations in the community, such as being a member of the National Federation of Coffee Growers, a quality represented by the possession of a coffee identification card that, in synergy with other variables, reduce inequality and poverty.

Authors: Topić Jakov , Škugor Branimir , Deur Joško
Published: January 2022

This paper deals with fuel consumption prediction based on vehicle velocity, acceleration, and road slope time series inputs. Several data-driven models are considered for this purpose, including linear regression models and neural network-based ones. The emphasis is on accounting for the road slope impact when forming the model inputs, in order to improve the prediction accuracy. A particular focus is devoted to conversion of length-varying driving cycles into fixed dimension inputs suitable for neural networks. The proposed prediction algorithms are parameterized and tested based on GPS- and CAN-based tracking data recorded on a number of city buses during their regular operation. The test results demonstrate that a proposed neural network-based approach provides a favorable prediction accuracy and reasonable execution speed, thus making it suitable for various applications such as vehicle routing optimization, synthetic driving cycle validation, transport planning and similar.

Published: January 2022

Plant invasion is significantly affected by environmental factors in the recipient habitats and affects the stability and sustainable development of society. The invasiveness of alien plants may be increased by anthropogenic-mediated disturbances, such as fluctuations in nutrients caused by excessive emissions of nitrogen (N) and phosphorus (P). To improve our understanding of the interactions between N and P fluctuations and invasive alien plants, the current report focuses on the biogeochemical behavior of N and P among invasive alien plants, native plants, and the soil within the plant–soil ecosystem. Our research, together with a synthesis of the literature, shows that fluctuations in N and P resources provide more opportunities and competitiveness for plant invasion. At the same time, the biogeochemical cycles of N and P are promoted because of their efficient and increased utilization and rate of release by invasive alien plants. However, there is no consensus on whether the N and P compositions of invasive species are different from those of the natives in their habitat. Quantitative studies that compare N and P contents in plant, litter, and soil between native plant communities and invaded communities on a global scale are an indispensable area of research focus for the future.
A Novel Approach of Integrating Natural Language Processing Techniques with Fuzzy TOPSIS for Product Evaluation
Authors: Wang Tianxiong
Published: January 2022

Product designers need to fully understand consumers’ emotional preferences and responses for product forms to improve products. However, users and designers have different understandings and concepts in the product evaluation process, which will lead to cognitive asymmetry in the product design and evaluating process. This phenomenon prevents designers to grasp users’ needs, increasing the risk of product development failure. To this end, this paper proposes a product evaluation method that combines natural language processing techniques and fuzzy multi-criteria decision-making into a new integrated way to reduce the cognitive difference between users and designers, so as to solve the problem of cognitive asymmetry. This was done firstly by obtaining the review data of products from users on the Internet, based on a web crawler, and then constructing word vectors based on natural language processing techniques to realize the parametric expression of the Kansei image. Secondly, by using a statistical method to extract the product scheme that meets the preferences of users and designers, and then quantifying the relationship between the product form and Kansei image based on a grey relational analysis (GRA). Finally, by calculating the indicator weight based on the Entropy method and using the fuzzy TOPSIS method to explore the prioritization of the product design alternatives in view of the Kansei needs of users. Taking the smart capsule coffee machine as an example, the feasibility and effectiveness of this method are verified. In particular, the method proposed in this research can not only enable different cognitive subjects to achieve cognitive symmetry, but also filter out product forms that meet the cognitive needs of users. Moreover, this study provides a theoretical basis and practical significance for reducing the cognitive differences between cognitive subjects in the whole process of product design, and provides a systematic framework for the industry to effectively connect customer needs and product design decisions. At the same time, this study has introduced a new method for Kansei engineering.
On Enhanced GLM-Based Monitoring: An Application to Additive Manufacturing Process

Published: January 2022

Innovations in technology assist the manufacturing processes in producing high-quality products and, hence, become a greater challenge for quality engineers. Control charts are frequently used to examine production operations and maintain product quality. The traditional charting structures rely on a response variable and do not incorporate any auxiliary data. To resolve this issue, one popular approach is to design charts based on a linear regression model, usually when the response variable shows a symmetric pattern (i.e., normality). The present work intends to propose new generalized linear model (GLM)-based homogeneously weighted moving average (HWMA) and double homogeneously weighted moving average (DHWMA) charting schemes to monitor count processes employing the deviance residuals (DRs) and standardized residuals (SRs) of the Poisson regression model. The symmetric limits of HWMA and DHWMA structures are derived, as SR and DR statistics showed a symmetric pattern. The performance of proposed and established methods (i.e., EWMA charts) is assessed by using run-length characteristics. The results revealed that SR-based schemes have relatively better performance as compared to DR-based schemes. In particular, the proposed SR-DHWMA chart outperforms the other two, namely SR-EWMA and SR-HWMA charts, in detecting shifts. To illustrate the practical features of the study’s proposal, a real application connected to the additive manufacturing process is offered.
Quo Vadis Nonlinear Optics? An Alternative and Simple Approach to Third Rank Tensors in Semiconductors

Published: January 2022

It is well understood that nonlinear optical (NLO) phenomena are deeply related to the material’s symmetry. Mathematically, the material symmetry can be described in terms of the nonzero parameters in the nonlinear susceptibility tensors. Generally, more complex structures involve more nonzero parameters in the tensor. The number of parameters increases rapidly if higher NLO orders are considered, complicating the physical analysis. Conventionally, these parameters are obtained via abstract symmetry analysis, e.g., group theory (GT). This work presents a novel theoretical analysis to approach the nonlinear tensor using the simplified bond hyperpolarizability model (SBHM) and compare it with GT. Our analysis is based on a light–matter interaction classical phenomenological physical framework. Rather than just looking at the symmetry of the crystal, the model applies physical considerations requiring fewer independent parameters in the tensor than GT. Such a simplification significantly improves the determination of the surface–bulk SHG contribution factors, which cannot be extracted from the experiment alone. We also show for the case of perovskite that the SHG contribution can be addressed solely from their surface dipoles with only one independent component in the tensor. Therefore, this work may open the path for a similar analysis in other complicated semiconductor surfaces and structures in the future, with potential applications to nanoscale surface characterization and real-time surface deposition monitoring.
Neurotoxic Potential of Deoxynivalenol in Murine Brain Cell Lines and Primary Hippocampal Cultures
Authors: Fæste Christiane Kruse , Solhaug Anita , Gaborit Marion , Pierre Florian , Massotte Dominique
Published: January 2022

Chronic exposure to the mycotoxin deoxynivalenol (DON) from grain-based food and feed affects human and animal health. Known consequences include entereopathogenic and immunotoxic defects; however, the neurotoxic potential of DON has only come into focus more recently due to the observation of behavioural disorders in exposed farm animals. DON can cross the blood-brain barrier and interfere with the homeostasis/functioning of the nervous system, but the underlying mechanisms of action remain elusive. Here, we have investigated the impact of DON on mouse astrocyte and microglia cell lines, as well as on primary hippocampal cultures by analysing different toxicological endpoints. We found that DON has an impact on the viability of both glial cell types, as shown by a significant decrease of metabolic activity, and a notable cytotoxic effect, which was stronger in the microglia. In astrocytes, DON caused a G1 phase arrest in the cell cycle and a decrease of cyclic-adenosine monophosphate (cAMP) levels. The pro-inflammatory cytokine tumour necrosis factor (TNF)-α was secreted in the microglia in response to DON exposure. Furthermore, the intermediate filaments of the astrocytic cytoskeleton were disturbed in primary hippocampal cultures, and the dendrite lengths of neurons were shortened. The combined results indicated DON’s considerable potential to interfere with the brain cell physiology, which helps explain the observed in vivo neurotoxicological effects.
M-Class Solar Flares in Solar Cycles 23 and 24: Properties and Space Weather Relevance
Authors: Miteva Rositsa , Samwel Susan W.
Published: January 2022

A comprehensive statistical analysis on the properties and accompanied phenomena of all M-class solar flares (as measured in soft X-rays) in the last two solar cycles (1996–2019) is presented here with a focus on their space weather potential. The information about the parent active region and the underlying sunspot (Hale) type is collected for each case, where possible, in order to identify photospheric precondition as precursors for the solar flare eruption or confinement. Associations with coronal mass ejections, solar energetic particles, and interplanetary radio emissions are also evaluated and discussed as possible proxies for flare eruption and subsequent space weather relevance. The results show that the majority (∼80%) of the analyzed M-class flares are of β, β-γ, and β-γ-δ magnetic field configuration. The M-class population of flares is accompanied by CMEs in 41% of the cases and about half of the flare sample has been associated with radio emission from electron beams. A much lower association (≲10%) is obtained with shock wave radio signatures and energetic particles. Furthermore, a parametric scheme is proposed in terms of occurrence rates between M-class flares and a variety of accompanied solar phenomena as a function of flare sub-classes or magnetic type. This study confirms the well-known reduced but inevitable space weather importance of M-class flares.

Published: January 2022

Oncolytic herpes simplex virus (oHSV) is a highly promising treatment for solid tumors. Intense research and development efforts have led to first-in-class approval for an oHSV for melanoma, but barriers to this promising therapy still exist that limit efficacy. The process of infection, replication and transmission of oHSV in solid tumors is key to obtaining a good lytic destruction of infected cancer cells to kill tumor cells and release tumor antigens that can prime anti-tumor efficacy. Intracellular tumor cell signaling and tumor stromal cells present multiple barriers that resist oHSV activity. Here, we provide a review focused on oncolytic HSV and the essential viral genes that allow for virus replication and spread in order to gain insight into how manipulation of these pathways can be exploited to potentiate oHSV infection and replication among tumor cells.

Published: January 2022

The evaluation of the hydrological responses of river basins to land-use and land-cover (LULC) changes is crucial for sustaining water resources. We assessed the impact of LULC changes (1990–2018) on three hydrological components (water yield (WYLD), evapotranspiration (ET), and sediment yield (SYLD)) of the Wami–Ruvu Basin (WRB) in Tanzania, using the Soil and Water Assessment Tool (SWAT). The 1990 LULC imagery was used for SWAT simulation, and imagery from 2000, 2010, and 2018 was used for comparison with modelled hydrological parameters. The model was calibrated (1993–2008) and validated (2009–2018) in the SWAT-CUP after allowing three years (1990–1992) for the warm-up period. The results showed a decrease in WYLD (3.11 mm) and an increase in ET (29.71 mm) and SYLD (from 0.12 t/h to 1.5 t/h). The impact of LULC changes on WYLD, ET, and SYLD showed that the increase in agriculture and built-up areas and bushland, and the contraction of forest led to the hydrological instability of the WRB. These results were further assessed with climatic factors, which revealed a decrease in precipitation and an increase in temperature by 1 °C. This situation seems to look more adverse in the future, based on the LULC of the year 2036 as predicted by the CA–Markov model. Our study calls for urgent intervention by re-planning LULC and re-assessing hydrological changes timely.
Rice Straw Biochar and Magnetic Rice Straw Biochar for Safranin O Adsorption from Aqueous Solution
Authors: Phuong Do Thi My , Loc Nguyen Xuan
Published: January 2022

This study investigates the adsorption of Safranin O (SO) from aqueous solution by both biochar and magnetic biochar derived from rice straw. Rice straw biochar (RSB) was made by pyrolysis in a furnace at 500 °C, using a heating rate of 10 °C·min−1 for 2 h in an oxygen-limited environment, whilst the magnetic rice straw biochar (MRSB) was produced via the chemical precipitation of Fe2+ and Fe3+. The physicochemical properties of the synthesized biochars were characterized using SEM, SEM- EDX, XRD, FTIR techniques, and N2 adsorption (77 K) and pHpzc measurements. Batch adsorption experiments were used to explore the effect of pH, biochar dosage, kinetics, and isotherms on the adsorption of SO. Experimental data of RSB and MRSB fit well into both Langmuir and Freundlich isotherm models, and were also well-explained by the Lagergren pseudo-second-order kinetic model. The maximum SO adsorption capacity of MRSB was found to be 41.59 mg/g, while for RSB the figure was 31.06 mg/g. The intra-particle diffusion model indicated that the intra-particle diffusion may not be the only rate-limiting step. The collective physical and chemical forces account for the adsorption mechanism of SO molecules by both RSB and MRSB adsorbents. The obtained results demonstrated that the magnetic biochar can partially enhance the SO adsorption capacity of its precursor biochar and also be easily separated from the solution by using an external magnet.

Published: January 2022

We present a case study of a Structural Health Monitoring (SHM) hybrid system based on Brillouin Distributed Fiber Optic Sensors (D-FOS), Vibrating Wire (VW) extensometers and temperature probes for an existing historical water penstock bridge positioned in a mountain valley in Valle d’Aosta Region, Northwestern Italy. We assessed Brillouin D-FOS performances for this kind of infrastructure, characterized by a complex structural layout and located in a harsh environment. A comparison with the more traditional strain monitoring technology offered by VW strain gauges was performed. The D-FOS strain cable has been bonded to the concrete members using a polyurethane-base adhesive, ensuring a rigid strain transfer. The raw data from all sensors are interpolated on a unique general timestamp with hourly resolution. Strain data from D-FOS and VW strain gauges are then corrected from temperature effects and compared. Considering the inherent differences between the two monitoring technologies, results show a good overall matching between strain time series collected by D-FOS and VW sensors. Brillouin D-FOS proves to be a good solution in terms of performance and economic investment for SHM systems on complex infrastructures such as hydropower plants, which involve extensive geometry combined with the need for detailed and continuous strain monitoring.

This article provides an analysis of the statistical data of the flash mob #неотвечатьгрубо. Its essence lies in the fact that one has to respond to a long-forgotten and ignored social media messages. According to the research 79% of the people ignored strangers. 66% of those who ignored were women, the largest number (41%) of ignored messages included messages from acquaintances who shared their plans or were interested in the life of the interlocutor, the most popular reaction to an unexpected message (53%), unfortunately, was ignoring this message. The reason for this might be the fact that the majority of the participants took a snapshot of the chats immediately after sending the message. Most likely, the addressees have not yet had time to read it.

Background: Hemophilia A (HA) is an X-linked recessive bleeding disorder with a high rate of genetic heterogeneity. The present study was conducted on a large cohort of Iranian HA patients and data obtained from databases. Methods: A total of 622 Iranian HA patients from 329 unrelated families who had been referred to a medical genetics laboratory in Tehran from 2005 to 2019, were enrolled in this retrospective, observational study. Genetic screening of pathogenic variants of the F8 gene was performed using inverse shifting PCR, direct sequencing, and multiplex ligation-dependent amplification (MLPA). Point mutation frequencies in different exons were analyzed for our samples as well as 6031 HA patients whose data were recorded in a database. Results: A total of 144 different pathogenic or likely pathogenic variants including 29 novel variants were identified. A strategy to decrease costs of genetic testing of HA was suggested based on this finding. Conclusion: This study provides comprehensive information on F8 pathogenic/likely pathogenic variants in Iranian HA patients which improves the spectrum of causative mutations and can be helpful to clinicians and medical geneticists in counseling and molecular diagnosis of HA.

The genetic status of a person is currently assigned a major role in the pathogenesis, diagnosis and treatment of various diseases. The most important genetic factors that have been attached great importance to are the genes of the glutathione-S-transferase family (GSTs). The genes of the glutathione-S-transferase family belong to the second phase of detoxification of xenobiotics and their altered activity leads to the development of many pathological conditions. GSTM, GSTT, GSTP are considered to be the most polymorphic. The issues of the participation of polymorphic GSTs in the development of infectious, allergic and oncological diseases, disorders of the reproductive system, as well as in the development of Alzheimer's disease are discussed in the article.

Objective: Study specific Igg4 antibodies to milk proteins indexes in healthy babies living in different Russian megalopolises.

Methods: The complex research of the specific Igg4 antibodies to milk proteins during cohort study of 259 healthy babies of the first year of life. Children lived in five Russian cities: 60 children in Moscow, 50 newborns – in Saint Petersburg, 55 children came from Kazan, 43 children lived in Khabarovsk and 51 – in Vladivostok. Non-competitive enzyme-linked immunosorbent assay was used to quantify specific Igg4 antibodies to cow milk proteins (CMP), beta-lactoglobulin (β-LG), alpha-lactalbumin (α-LA), casein and goat's milk protein (GM) in coprofiltrates

Results: The highest frequency of the high Igg4 was discovered to CMP and goats’ milk was observed among children from Saint Petersburg during comparative assessment of the frequency of defining Igg4 to milk proteins in healthy newborns aged 2.5 months living in Moscow and Saint-Petersburg. The highest frequency of Igg4 increased rates to milk proteins among newborns from Kazan, Khabarovsk and Vladivostok was diagnosed during first three months of life on breastfeeding without any clinical symptoms of food intolerance. With age decrease of the frequency of specific Igg4 to milk proteins were observed among all babies from above-mentioned cities. By 8 month of life it made isolated cases.

Conclusions: High frequency of increased Igg4 to milk proteins among 2 months old babies on breastfeeding was observed in the cities of Central and Far Eastern districts of Russian Federation. In this regard it can be supposed that Igg4s were got from mothers in the prenatal period and after birth through breastfeed. The presence of high frequency of the increased indexes of specific Igg4 to milk proteins probably was related to mothers’ nutrition habits during pregnancy and lactation periods.

Ethanol as an alternative to water vapor for saving energy and fossil fuels in thermoelectric plants
Authors: Hernández-Medina José Juan , Pérez-Martínez René , López-Xelo Hilario
Published: January 2022

This article proposes the use of ethanol in a 96% azeotropic mixture as an alternative to water vapor in thermoelectric generators with notable advantages in saving fuel. As is known, water is a cheap resource, available everywhere in a liquid state. However, water has an unusually high heat of vaporization and an equally high boiling point, so converting water to steam requires consuming large amounts of fossil fuels to break the hydrogen bonds in this substance. In contrast, evaporating ethanol requires only 37 percent of the fuel needed to evaporate water. In addition, water, before turning into steam, needs to be softened and treated with chemicals to prevent oxidation and scale deposits in pipes. If quality ethanol is used, this process of adjusting the water would not be necessary, which represents another saving. On the other hand, it is possible to resort to the use of solar heaters to raise the temperature of the ethanol to around 70ºC to later heat it to 80ºC or more, if necessary, with fossil fuels, making more significant savings. Objectives: To propose the replacement of water vapor by ethanol vapor as a working fluid to move the turbines of thermoelectric plants to reduce the consumption of fossil fuels. Methodology: Analyze the physical properties of water and compare them with those of ethanol to know the advantages and disadvantages of one and the other as working fluids Contribution: Through small modifications in thermoelectric plants it is possible to reconvert them to operate with ethanol vapor and save on fossil fuels.

The article focuses on one of the pressing problems of modern humanitarian knowledge - the problem of self-identification of hybrid cultures, in particular, the culture of the Finnish Americans. The ethnic diversity of the United States leads to a constant intersection of various cultures, giving rise to the uniqueness of contemporary American literary life. National, cultural, personal identity associated with the revision of the traditions that were assimilated in their diaspora acts as the main problem of multiculturalism - the ideology of plurality and diversity. Self-identification strategies may include the definition of one's religious, ethnic, gender determination. Very often, the community's collective trauma and collective memory of the historical past can act as a strategy. The main strategies of ethnic and cultural self-identification of Finnish American literature are represented by the collective memory, collective trauma, “Finnishness”, and the national Finnish epic “Kalevala”, which is used as a source of archetypal images and poetic imagination. Basing on a number of works by Finnish American writers of the second half of the 20 and 21 centuries in different genres (science fiction, historical novel, short stories), the article examines the creative application of the Finnish epic “Kalevala”, integrated into the experience of American existence as one of the main strategies for self-identification of its own culture, which is built on the dialogical interaction of the Anglo-Saxon and Finnish cultures. The article actualizes the problems of the interrelations of the two cultures, the transformation of archetypal images, the reflection of collective memory in the works of contemporary Finnish American writers.

High-NA EUV lithography: current status and outlook for the future
Authors: Levinson Harry J.
Published: January 2022

High-NA extreme ultraviolet (EUV) lithography is currently in development. Fabrication of exposure tools and optics with a numerical aperture (NA) equal to 0.55 has started at ASML and Carl Zeiss. Lenses with such high NA will have very small depths-of-focus, which will require improved focus systems and significant improvements in wafer flatness during processing. Lenses are anamorphic to address mask 3D issues, which results in wafer field sizes of 26 mm × 16.5 mm, half that of lower NA EUV tools and optical scanners. Production of large die will require stitching. Computational infrastructure is being created to support high-NA lithography, including simulators that use Tatian polynomials to characterize the aberrations of lenses with central obscurations. High resolution resists that meet the line-edge roughness and defect requirements for high-volume manufacturing also need to be developed. High power light sources will also be needed to limit photon shot noise.

Published: January 2022

ScAlN films are currently being investigated for their potential use in surface acoustic wave (SAW) devices for next-generation mobile networks because of their high piezoelectricity. This paper describes the numerical simulation of SAW propagation in c-axis-tilted ScAlN films on silicon substrates and a fabrication technique for preparing c-axis-tilted ScAlN films on silicon substrates. The electromechanical coupling coefficient K
2 of SAW propagating in the ScAlN film/silicon substrate increased due to the c-axis tilt angle. The maximum K
2 value is approximately 3.90%. This value is 2.6 times the maximum K
2 value of the c-axis-oriented ScAlN film/silicon substrate structure. The c-axis-tilted ScAlN films with an Sc concentration of 40% were prepared on a silicon substrate via RF magnetron sputtering based on the self-shadowing effect, and the maximum c-axis tilt angle was 57.4°. These results indicate that this device structure has the potential for SAW device applications with well-established micromachining technology derived from silicon substrates.

Published: January 2022

We have developed optical-interference contactless thermometry imaging technique to visualize three-dimensional transient temperature distribution in 4H-SiC Schottky barrier diode (SBD) under operation. When a 1 ms forward pulse bias was applied, clear variation of optical interference fringes induced by self-heating and cooling were observed. Thermal diffusion and optical analysis revealed three-dimensional temperature distribution with high spatial (≤10 μm) and temporal (≤100 μs) resolutions. A hot spot that signals breakdown of the SBD was successfully captured as an anomalous interference, which indicated a local heating to a temperature as high as 805 K at the time of failure.

Published: January 2022

Edge/fog computing is a key enabling technology in 5G and beyond for fulfilling the tight latency requirements of emerging vehicle applications, such as cooperative and autonomous driving. Vehicular Fog Computing (VFC) is a cost-efficient deployment option that complements stationary fog nodes with mobile ones carried by moving vehicles. To plan the deployment and manage the VFC resources in the real world, it is essential to take into account the spatio-temporal variations in both demand and supply of fog computing capacity and the trade-offs between achievable Quality-of-Services and potential deployment and operating costs. Concerning the complexity and the economic load of real-world measurements, simulation becomes a better option at the early research phase to validate capacity and resource management solutions in various urban environments. The existing simulation platforms cannot provide a realistic techno-economic investigation to analyze the implications of VFC deployment options, due to the simplified network models in use, the lack of support for fog node mobility, and limited testing scenarios. In this paper, we propose an open-source simulator VFogSim that allows real-world data as input for simulating the supply and demand of VFC in urban areas. It follows a modular design to evaluate the performance and cost-efficiency of different deployment scenarios under various vehicular traffic models, and the effectiveness of the diverse network and computation schedulers and prioritization mechanisms under user-defined scenarios. Compared with the existing edge/fog computing simulators, such as IFogSim, IoTSim, and EdgeCloudSim, to the best of our knowledge, our platform is the first one that supports the mobility of fog nodes and provides realistic modeling of V2X in 5G and beyond networks in the urban environment. Furthermore, we validate the accuracy of the platform using a real-world 5G measurement and demonstrate the functionality of the platform taking VFC capacity planning as an example.
