Alternative methods of production and consumption as tools for solving global problems of modern society and implementing the principles of sustainable development
Authors: Khasanova M.S. , Saidulgerieva M.A.
Published: January 2024

At the end of the 60s of the 20th century, a transformation of human civilization took place, which entered a qualitatively new state. During this period, the term “global problems” appeared in the scientific literature. In the context of scientific and technological progress, the load on the environment in terms of greater anthropogenic impact is increasing, thereby creating an objective need to find new ways to prevent environmental disaster. At the end of the 20th century, a direction in economics called the “green economy” was formed, designed to reduce the negative impact on the environment and solve the global problems of today’s realities through the use of green technologies. In this direction, both legislative (tax regulation in the field of anthropogenic impact) and the introduction of alternative energy sources, as well as the preservation of existing national natural resources, are applied. With the advent of the “green economy” concept, many new elements of regulating the economy and the harmful effects of human industrial activity on nature have been introduced into world practice. One such element is the cross-border carbon tax, which is being introduced by the European Union. This tax is an additional charge on the import of goods with a large carbon footprint into the European Union. It is unprofitable for the economies of many countries that import raw materials and supplies to the countries of the European Union, but it is necessary, since global warming, which is a consequence of human industrial activity, can lead to disastrous consequences in the future. The purpose of the work is to identify the main problems of human and social development and find ways to solve them, determine the impact of the new tax on the state of the environment.
Administration of Antenatal Corticosteroids: Optimal Timing
Authors: Berger Richard , Stelzl Patrick , Maul Holger
Published: January 2024

The effectiveness of antenatal corticosteroids (ACS) in significantly reducing respiratory distress syndrome (RDS) depends crucially on the timing. It is successful if delivery takes place
between 24 hours and seven days following administration; after this period, the side effects seem to predominate. In addition, an increased rate of mental impairment and behavioral
disorders are observed in children born full-term after ACS administration. The optimal timing of ACS administration depends crucially on the given indication; to date, it has been achieved
in only 25–40% of cases. ACS administration is always indicated in PPROM, in severe early pre-eclampsia, in fetal IUGR with zero or reverse flow in the umbilical artery, in placenta previa
with bleeding, and in patients experiencing premature labor with a cervical length < 15 mm. The risk of women with asymptomatic cervical insufficiency giving birth within seven days is
very low. In this case, ACS should not be administered even if the patient’s cervical length is less than 15 mm, provided that the cervix is closed and there are no other risk factors for a
premature birth. The development of further diagnostic methods with improved power to predict premature birth is urgently needed in order to optimize the timing of ACS administration in this
patient population. Caution when administering ACS is also indicated in women experiencing premature labor who have a cervical length ≥ 15 mm. Further studies using amniocentesis are needed
in order to identify the patient population with microbial invasion of the amniotic cavity/intra-amniotic infection (MIAC/IAI), and to define threshold values at which delivery is indicated.
ACS administration is not performed as an emergency measure, usually not even before transfer to a perinatal center. Therefore, whenever possible, the indication for ACS administration
should be determined by a clinician who is highly experienced in perinatology.
Mapping Injection Order Messages to Health Level 7 Fast Healthcare Interoperability Resources to Collate Infusion Pump Data
Authors: Doi Shunsuke , Yokota Shinichiroh , Nagae Yugo , Takahashi Koichi , Aoki Mitsuhiro , Ohe Kazuhiko
Published: January 2024

Background When administering an infusion to a patient, it is necessary to verify that the infusion pump settings are in accordance with the injection orders provided by the physician. However, the infusion rate entered into the infusion pump by the health care provider cannot be automatically reconciled with the injection order information entered into the electronic medical records (EMRs). This is because of the difficulty in linking the infusion rate entered into the infusion pump by the health care provider with the injection order information entered into the EMRs.

Objectives This study investigated a data linkage method for reconciling infusion pump settings with injection orders in the EMRs.

Methods We devised and implemented a mechanism to convert injection order information into the Health Level 7 Fast Healthcare Interoperability Resources (FHIR), a new health information exchange standard, and match it with an infusion pump management system in a standard and simple manner using a REpresentational State Transfer (REST) application programming interface (API). The injection order information was extracted from Standardized Structured Medical Record Information Exchange version 2 International Organization for Standardization/technical specification 24289:2021 and was converted to the FHIR format using a commercially supplied FHIR conversion module and our own mapping definition. Data were also sent to the infusion pump management system using the REST Web API.

Results Information necessary for injection implementation in hospital wards can be transferred to FHIR and linked. The infusion pump management system application screen allowed the confirmation that the two pieces of information matched, and it displayed an error message if they did not.

Conclusion Using FHIR, the data linkage between EMRs and infusion pump management systems can be smoothly implemented. We plan to develop a new mechanism that contributes to medical safety through the actual implementation and verification of this matching system.
Employee work engagement in the digital transformation of enterprises: a fuzzy-set qualitative comparative analysis
Authors: Ye Di , Xu Bin , Wei Bingling , Zheng Linlin , Wu Yenchun Jim
Published: January 2024

Information technology has brought about significant changes in enterprises, and new work situations have led to new problems. Employee resistance to new technologies, their ability to learn, and their ability to utilize personal resources to improve work engagement in the face of technological pressure are important factors that companies need to consider when undergoing digital transformation. The influence mechanism of configuration effects on factors around employee work engagement has not been explored, and technostress creators have rarely been included in the configuration as influencing factors in previous studies. On the basis of the job demands-resources (JD-R) model and trait activation theory, this study explored the factors that affect employees’ work engagement at the level of job demands and personal resources. The fuzzy-set qualitative comparative analysis (fsQCA) method was used to investigate the influence of technical stressors, self-efficacy, and the Big Five personality traits on employees’ work engagement. Through a survey of 225 employees in the context of enterprise digital transformation, the results show three driving paths that promote employees’ work engagement: openness to experience conscientiousness, self-efficacy driven, and inhibition to technical stressors. The study also analyzed employees’ low work engagement state, which is driven by an inhibition of agreeableness and extraversion. This research enriches the study of factors influencing work engagement in the digital transformation of enterprises.
Examination of HRM practices in relation to the retention of Chinese Gen Z employees
Authors: Ali Hazem , Li Min , Qiu Xunmin
Published: January 2024

Employee retention has attracted the attention of both scholars and practitioners, especially with the gradual entry of Gen Z employees into the workplace. HRM literature indicates that the employee retention research stream in the context of Gen Z employees requires further development. Based on an exploratory study, this research has identified four HRM practices influencing the retention of Gen Z employees: supportive working environment, pay, training and development, and role clarity. An empirical investigation using 529 questionnaires was used to examine the impact of these HRM practices on retaining Gen Z employees with an emphasis on the moderating role of employee gender. The findings of PLS-SEM showed that the four HRM practices have a significant effect on employee retention. The multi-group PLS analysis revealed that a supportive working environment and training and development practices are more important for female employees, whereas pay and role clarity had a salient impact on retaining male employees. Based on the empirical findings, HR managers may devise suitable intervention mechanisms to encourage the retention of Gen Z employees through maintaining a supportive work environment, providing fair and competitive pay, providing effective training and development, and clarifying job duties and responsibilities.
The role of personal connections Wasta on early-stage entrepreneurial orientations: empirical evidence from Saudi Arabia
Authors: Albihany Naeem A. , Aljarodi Abdullah M.
Published: January 2024

Wasta (Nepotism) is a controversial concept and practice used in the Arab world, which is an informal networking style. A good number of studies have been published in this field, but concerning Wasta in relation to entrepreneurial orientation, “EO” is very limited. Based on institutional theory, this quantitative research aims to analyze the relationship between Wasta from the provider and receiver sides as an informal institution and the EO of entrepreneurs in three main regions of Saudi Arabia. Using the STATA program, Exploratory Factor Analysis and Multilevel regression models were applied to test the study propositions with a sample of Saudi early-stage entrepreneurs. Results reveal two significant findings: (1) the respondents in the Western region of Saudi tend to have a significant relationship with Receiving Wasta Activities as an independent factor and EO dimensions in terms of Innovativeness and Proactiveness, Autonomy and Risk-taking, while respondents in the Central region, only found to be significant with Autonomy and Risk-taking; and (2) the evidence shows that Competitive Aggressiveness, was only found to be significant in Providing Wasta Activities. This study contributes to the current knowledge by empirically finding the significant relationship between Wasta activities from the provider and receiver sides and the four dimensions of OEs amongst early-stage entrepreneurs in Saudi Arabia. The findings also are significant for policymakers and organizations to advocate their communication and networking channels. Limitations and future research lines are discussed.
How does industrial policy experimentation influence innovation performance? A case of Made in China 2025
Authors: Chen Kejing , Meng Qiaoshuang , Sun Yutao , Wan Qingqing
Published: January 2024

Made in China 2025 (MIC 2025), an industrial policy, aims to position China among the global leading manufacturing powers. Different from other industrial policies in China, MIC 2025 is implemented by policy experimentation of pilot cities, which gives priority to the local governments. However, whether MIC 2025 pilot cities promote firm innovation is unclear in current literature. Using MIC 2025 pilot cities as a quasi-natural experiment, this study analyzes the effect and the mechanism of MIC 2025 on firm innovation. The sample consists of 4422 firm-year observations of Chinese listed manufacturing firms in 2012–2022. The result indicates that focal firm located in MIC 2025 pilot cities facilitates its innovation. Mechanism analysis show that MIC 2025 promotes firm innovation through tax incentives, public subsidies, convenient financing, academic collaboration and talent incentives. This study extends industrial policy literature with regard to how place-based policy experimentation promote the implementation of China’s industrial policies. Local governments’ participations and their interaction with the central government are vital for a successful policy experimentation.
Contract management of municipal public services: the Slovak experience
Authors: Mikušová Meričková Beáta , Nemec Juraj , Jakuš Muthová Nikoleta
Published: January 2024

Contracting out services in the public sector should convey efficiency gains compared to the in-house delivery of these services because of the competition element. However, results from practice do not confirm this assumption. Generalising the reasons for this situation is still problematic, but there is no doubt that the quality of managing the processes of contracting out of public services should be the factor. The aim of this paper is to contribute to the discussion on contract management in the public sector by analysing the quality of contract management in Slovak municipalities in the context of contracting out risks as defined by the principal-agent theory. The study uses own methodological approach for quantifying the determinants of the quality of contract management in relation to the contracting out risks using Saaty’s expert method. In total, 7 variables were constructed, and 3416 contracts are evaluated. Similarly to most existing studies, the results indicate severe problems in the quality of contract management in municipal sector, which increase the risks associated with contracting out. The most prevalent reserves in the quality of contract management of contracted local public and ancillary services in the Slovak municipal conditions are related to the selection of the public procurement procedure; the irregular monitoring of the quality of external production; and the type of payment. The outcomes clearly show that potential increases in efficiency via contracting out are unequivocally limited by the low quality of contract management.
On the Chinese resistance to lexical borrowing: a writing-driven self-purification system
Authors: Zhang Liulin
Published: January 2024

The Chinese language is known for its resistance to lexical borrowing. Transliterations can hardly be retained in this language that use pre-existing characters to simply transcribe the pronunciation of the source word in the donor language. This exclusion can be attributed to the ideographic nature of Chinese characters. Given the stable graphic-meaning correspondence, novel use of characters is expected to be consistent with their usage in previous literature, while the association between the graphic form and the phonetic form has always been loose, rendering it meaningless to use characters as a mere phonetic representation. Here writing is having an effect on the assimilation of loanwords, and more generally, the purist language ideology, which runs counter to the traditionally assumed derivative position of writing, thus shedding light on the implicit effect of writing on language ideology.
Enhancing customer value co-creation and stickiness in social commerce: integrating PLS-SEM and NCA for deeper insights into customer-to-customer dynamics
Authors: Zhou Ying , Kumar Sameer , Furuoka Fumitaka
Published: January 2024

Social commerce(s-commerce), which emphasizes the predominance of customers, has become an important tool of company social marketing and provides new challenges to businesses in attracting customers. Based on customer-dominant logic theory, this study presents a model of the impact of electronic customer-to-customer interaction(eCCI) on customer stickiness with the mediation effect of customer value co-creation dimensions, specifically functional value and hedonic value in the s-commerce context and self-efficacy as a moderator in light of customer-dominant logic. This study adopted a survey method and obtained data from users in two s-commerce sites in China. The statistical technique of partial least squares structural equation modeling (PLS-SEM) and the analytical process of necessary condition analysis (NCA) were employed to analyze the data. The PLS-SEM results indicate that eCCI influences customer value co-creation, which in turn affects the consumer stickiness of s-commerce sites.The moderated mediation results showed that self-efficacy moderated the relationship between eCCI and customer stickiness.The NCA results identified the eCCI is meaningful and significant necessary conditions for fostering customer value co-creation and customer stickiness. The combined findings demonstrated to researchers and practitioners how to identify the critical factor that influence customer value co-creation and customer stickiness. The study provides novel insights into the mechanism underlying why consumers “stick” to s-commerce websites. Furthermore, the moderated mediation model extended customer-dominant logic and demonstrated the moderating influence of self-efficacy. The theoretical and practical implications of these findings are discussed.
Lean blowout detection using topological data analysis

Published: January 2024

Modern lean premixed combustors are operated in ultra-lean mode to conform to strict emission norms. However, this causes the combustors to become prone to lean blowout (LBO). Online monitoring of combustion dynamics may help to avoid LBO and help the combustor run more safely and reliably. Previous studies have suggested various techniques to early predict LBO in single-burner combustors. In contrast, early detection of LBO in multi-burner combustors has been little explored to date. Recent studies have discovered significantly different combustion dynamics between multi-burner combustors and single-burner combustors. In the present paper, we show that some well-established early LBO detection techniques suitable for single-burner combustor are less effective in early detecting LBO in multi-burner combustors. To resolve this, we propose a novel tool, topological data analysis (TDA), for real-time LBO prediction in a wide range of combustor configurations. We find that the TDA metrics are computationally cheap and follow monotonic trends during the transition to LBO. This indicates that the TDA metrics can be used to fine-tune the LBO safety margin, which is a desirable feature from practical implementation point of view. Furthermore, we show that the sublevel set TDA metrics show approximately monotonic changes during the transition to LBO even with low sampling-rate signals. Sublevel set TDA is computationally inexpensive and does not require phase-space embedding. Therefore, TDA can potentially be used for real-time monitoring of combustor dynamics with simple, low-cost, and low sampling-rate sensors.

The rapid change of wind speed and direction on 21 August 2017 is studied using Doppler lidar measurements at five sites of the Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) facility in north-central Oklahoma. The Doppler lidar data were investigated along with meteorological variables such as temperature, humidity, and turbulence available from the large suite of instrumentation deployed at the SGP Central Facility (C1) during the Land-Atmosphere Feedback Experiment in August 2017. Lidar measurements at five sites, separated by 55–70 km, allowed us to document the development and evolution of the wind flow over the SGP area, examine synoptic conditions to understand the mechanism that leads to the ramp event, and estimate the ability of the High-Resolution Rapid Refresh model to reproduce this event. The flow feature in question is an atmospheric bore, a small-scale phenomenon that is challenging to represent in models, that was generated by a thunderstorm outflow northwest of the ARM SGP area. The small-scale nature of bores, its impact on power generation, and the modeling challenges associated with representing bores are discussed in this paper. The results also provide information about model errors between sites of different surface and vegetation types.
Synchronous magnetization to weaken the hindrance of surfactants to droplet coalescence during electric dehydration
Authors: Guo Kai , Du Ling , Lü Yuling , Bai Yin , He Limin , Luo Xiaoming
Published: January 2024

Electric dehydration is the most widely used physical technology for separating water from crude oil. However, natural surfactants stabilize the oil–water interface, resulting in low dehydration efficiency and failure of the electric dehydrator due to electric field collapse. To explore the physical methods of weakening the influence of surfactants on electric dehydration, this study synchronously increased magnetization during the electric dehydration. Based on high-speed microscopy experiments, it has been demonstrated that synchronous magnetization weakens the hindrance of surfactants to droplet coalescence during electric dehydration. Within the experimental conditions, the influence of magnetization on the growth coefficient C1 ranges from 2.9% to 26.6%. In addition, based on molecular dynamics simulation, the mechanism of magnetization weakening the influence of surfactants was studied at the molecular level. It was found that water molecules and surfactant molecules undergo significant molecular clusters after magnetization, reducing the influence degree of surfactants on unit area. When the surfactant concentration increases, the decrease in the influence degree is balanced by the increase in the number of molecules, which also explains the law that the improvement rate ΔC1 decreases with the increase in surfactant concentration. The results of this work will be potentially valuable for weakening surfactant barriers to demulsification and oil–water separation.

Published: January 2024

Thermoelectric materials and devices have the potential to directly convert heat into electricity, making them crucial for advancing the energy structure system and achieving the dual-carbon goal. However, the conventional methods of preparing thermoelectric materials and designing devices still face significant challenges, limiting the widespread application of thermoelectric technology. Ferromagnetic metal heterostructured nanomultilayers play a crucial role in generating, transporting, and detecting spin currents. Studying the properties and physical mechanisms of spin-dependent magnetic-thermal-electrical effects in the core material is essential for advancing spin thermoelectrics in the future. In this paper, we investigate the spin-related thermoelectric effects in artificial spin-valve heterostructured nanomultilayers. The spin-current generating layer is made of rare-earth garnet, while the spin-current detecting layer consists of ferromagnetic alloy thin films with different compositions of Fe–Co. It is being investigated to obtain thermal voltage signals with excellent stability and high resolution as well as to achieve the amplification and positive/negative adjustment of these signals. This study can serve as a reference for designing thermoelectric materials and aiding in the development of future high-efficiency spin-thermoelectric conversion devices.
Bubble rising near a vertical wall: Experimental characterization of paths and velocity
Authors: Estepa-Cantero C. , Martínez-Bazán C. , Bolaños-Jiménez R.
Published: January 2024

Trajectories of a single bubble rising in the vicinity of a vertical solid wall are experimentally investigated. Distinct initial wall-bubble distances are considered for three different bubble rising regimes, i.e., rectilinear, planar zigzag, and spiral. The problem is defined by three control parameters, namely, the Galilei number, Ga, the Bond number, Bo, and the initial dimensionless distance between the bubble centroid and the wall, L. We focus on high-Bond numbers, varying L from 1 to 4, and compare the results with the corresponding unbounded case, L→∞. In all cases, the bubble deviates from the expected unbounded trajectory and migrates away from the wall as it rises due to the overpressure generated in the gap between the bubble and the wall. This repulsion is more evident as the initial wall-bubble distance decreases. Moreover, in the planar zigzagging regime, the wall is found to impose a preferential zigzagging plane perpendicular to it when L is small enough. Only slight wall effects are observed in the velocity or the oscillation amplitude and frequency. The wall migration effect is more evident for the planar zigzagging case and less relevant for the rectilinear one. Finally, the influence of the vertical position of the wall is also investigated. When the wall is not present upon release, the bubbles have the expected behavior for the unbounded case and experience the migration only instants before reaching the wall edge. This repulsion is, in general, more substantial than in the initially present wall case.

Published: January 2024

The development of thin-film thermoelectric generators for micro-energy harvesting is highly anticipated. In this study, we have investigated the synthesis and thermoelectric applications of ternary alloy InAs1−xSbx thin films, which are narrow-gap III–V compound semiconductors. Polycrystalline InAs1−xSbx thin films with sub-micrometer grain size were synthesized on glass using molecular-beam deposition at 400 °C with all composition x. The InAs1−xSbx thin films exhibited n-type conduction, and their electrical and thermoelectric properties were strongly dependent on x and the amount of Sn doping. The ternary alloying reduced the power factor and contributed to a reduction in thermal conductivity. The InAs0.2Sb0.8 thin film on a glass substrate exhibited a power factor of 100 μW m−1 K−2 and a thermal conductivity of 2.0 W m−1 K−1 at room temperature. Furthermore, a comparable performance was demonstrated for an InAs0.2Sb0.8 thin film grown on a plastic film. These achievements will pave the way for the application of III–V compound semiconductors in flexible thermoelectric generators.

Published: January 2024

Efficient and broadband forward-scattering is a property of prime importance for meta-atoms if they are to be used in self-assembled metasurfaces. Strong contenders include colloidal nanoresonators with tailored multipolar content to achieve proper interferences that suppress back-scattering. We consider dense plasmonic balls composed of more than a hundred silver nanoinclusions. Numerical simulations provide a full understanding of the role played by multipole moments in the scattering behavior. They are fabricated using emulsion drying and characterized optically. Strong and efficient forward-scattering is demonstrated over the entire visible range. Electric and magnetic dipole resonances of equal amplitude and phase are evidenced. Such plasmonic balls could be used as meta-atoms for bottom-up metasurface applications.
A pneumatic particle-blocking variable-stiffness bending actuator
Authors: Peng He , Wang Xia , Geng Dexu
Published: January 2024

This study introduces a variable-stiffness pneumatic bending actuator to enhance the stiffness of flexible robots. The bending actuator combines the working principles of a pneumatic drive, a wedge structure, and particle blockage. It enables one-dimensional, bidirectional bending motion and offers pose-maintenance capabilities. The approach to variable-stiffness is both driven and antagonistic. Stiffness in both bending and opposite directions is nonlinearly correlated with air pressure values. Specifically, at 0.5 MPa of air pressure, the stiffness in the bending direction increases to 6.1 times the initial stiffness. At 0.15 MPa, the stiffness in the opposite direction is 2.1 times the initial value. When air pressure is greater than 0.15 MPa, the stiffness incrementally increases due to the wedge impedance force. A driven variable-stiffness control is simple and suitable for applications with a constant load direction, while the antagonistic approach is more suitable for occasions where the load direction changes during movement.

Published: January 2024

In this post-Moore era, on-chip components have transitioned into the “more Moore” and “more than Moore” technology routes. Serving as the foundational point and data source for all intelligent devices, sensors are undergoing development for multifunctionality, systematization, and integration. However, the current micro/nano multifunctional sensor fabrication technology is not sufficiently advanced to meet the requirements of practical applications. In this study, we prepared high-precision microwire arrays as multifunctional microsensors. This microsensor exhibited a highly sensitive response to humidity and bending strain. It has a sensitivity of up to 8520% and response time as low as 0.9/3.5 s (response/recovery) over a wide range of humidity variations from 23% to 97%. In the bending strain range of −0.4–0.4%, the microsensor exhibits a gauge factor of up to 267. This multifunctional microsensor has the potential for use in integrated intelligent devices.
Exploring the role of physician associates in Aotearoa New Zealand primary health care
Authors: Andrew Albert
Published: January 2024

Introduction New Zealand’s health care system faces significant shortages in health care workers. To address workforce challenges and meet the population’s health needs, health care systems around the world have introduced new clinical roles, such as physician associates/assistants (PAs) into existing health care teams. Aim This article aims to examine the benefits, challenges, and broader implications of regulating PAs in the context of New Zealand’s primary care sector, with a specific emphasis on how it may impact general practice. Methods A range of literature surrounding the role, impact, and perception of PAs were selected and included in this article. Results The PA profession can significantly strengthen New Zealand’s primary care workforce, improving patient access and continuity of care. However, the global deployment of PAs has faced scrutiny due to concerns about its potential risks to patient safety and the overall viability of such a role. Discussion If regulated, the PA profession can reshape New Zealand’s primary care, offering a partial solution to current medical staff shortages. Trained under a generalised medical model similar to doctors, PAs possess the necessary skills to perform both routine and non-routine medical tasks. This dual capability can significantly improve primary care service provision, reduce existing workloads, and allow for a more efficient deployment of doctor expertise. However, medico-legal issues and the supervisory burden can impede widespread integration into general practice. Despite challenges, the success of the PA role relies on mutual trust, respect, and support from other clinical team members within primary health care.
Online public denunciation as recursive social practice
Authors: Haugh Michael
Published: January 2024

Incidents of online public shaming commonly start when a record of conduct that is perceived as transgressive by
either one of the parties to that interaction or a third party observer is posted, in the form of a narrative description,
photograph, audio/video-recording, screenshot, and so on to an online platform, followed by viral amplification of that online
public denunciation post through sharing by others within and across platforms. Building on an analysis of 26 incidents of online
public denunciations of public incivilities it is argued, in this paper, that public denunciations essentially involve inviting
networked audiences to denounce entextualized moments of conduct, which are recontextualized as not only morally transgressive,
but as also warranting public condemnation. It is proposed that the procedure by which online public denunciations are
accomplished is thus recursive, as it not only involves the ascription of action to prior conduct of the target in question that
construes that prior conduct as transgressive, but the embedding of the ascription of that complainable action within a public
denunciation that invites condemnation of that ascribed action. However, since social media platforms allow for the
re-entextualization and subsequent recontextualization of prior posts through which public condemnation has been invited, online
public denunciations are themselves inevitably open to recursive recontextualization. It is concluded that online public
denunciation is thus an inherently recursive form of social practice.

Published: January 2024

A device constructed from metamaterials is proposed, which makes asymmetric transmission and reflection achieved in addition to a perfect dual-band unidirectional reflectionlessness at THz frequencies for linearly polarized incident waves. Owing to the unique structure characteristics, it exhibits an excellent performance of converting linear to circular polarization at multiple frequencies. Moreover, the maximum of PCR reaches 99.94%, and the ellipticity approaches 1 at eight frequencies. Additionally, UR and AT are achieved within broad ranges of the incidence angle θ and distance d between two resonators. Utilization of the metamaterial design will facilitate the multifunctionality of THz meta-device and promote the further advancements in integrated processes, communication, radar and other fields.
Photogenerated electron- and hole-trap distributions in Al-doped anatase TiO2 crystals measured by cryogenic EPR imaging
Authors: Kitao Yamato , Matsuoka Hideto , Murano Ayane , Sekiya Takao , Akimoto Ikuko
Published: January 2024

Electron paramagnetic resonance (EPR) imaging was performed on aluminium-doped anatase titanium dioxide (TiO2) crystals to demonstrate the distributions of photogenerated trapped electrons and holes at cryogenic temperatures. Complementary distributions of trapped electrons and holes were observed at 25 K; trapped electrons were predominant on the {101} planes, whereas trapped holes were predominant on the (001) and {110} planes in the tetragonal crystal structure. These separate distributions are consistent with the reported facet-dependent photocatalytic efficiency of photoreduction and photooxidation in anatase crystals, resulting from crystal plane-dependent carrier transfer. By this extrinsic trap system, the carrier transport properties were derivatively extracted through electron and hole traps. This report provides insight into the fundamental physics governing the facet dependence of photocatalytic effects.
Analytical and numerical computation of self-oscillating gels driven by the Belousov-Zhabotinsky reaction
Authors: Chi Zhai
Published: January 2024

Self-oscillating gel is a class of deformable polymers driven by Belousov-Zhabotinsky (BZ) reactions, which can form periodic deformations without any external stimuli, and are widely used in the research of micro actuators, AI sensors, drug release carriers or biomimetic materials. However, quantitative study on formation of the self-oscillating gel is limited especially from the perspective of energy conservation. This work adopts frequency domain analysis to the chemo-mechanical model, and the basic frequency is obtained to evaluate the maintenance energy of the deformable gel. For accurate computation, boundary value problem with unknown period is formulated; then, continuation algorithm based on technique of perturbation is performed to obtain the periodic trajectories with varying model parameters. The results could be implemented to design self-oscillating gels with prescribed periodicity.
Parametric assessment of electrical discharge drilling on plasma sprayed functionally graded Al/Al2O3 coating on Al6061-T6 faceplates
Authors: Rajeshshyam R , Muniraj D , Sreehari V M
Published: January 2024

Electrical discharge drilling is a non-conventional machining process that is effective and economical for cutting difficult-to-cut conductive materials. In this work, the parametric assessment of functionally graded Al/Al2O3 coating sprayed by plasma on Al6061-T6 faceplates is investigated. Initially, four different graded layers of Al/Al2O3 (50:50, 40:60, 30:70, and 20:80) were processed through plasma spray and deposited coating morphology, splat formation, and cross-sectional structure were confirmed through a scanning electron microscope. The parametric assessment has been investigated based on the effect of electrical discharge drilling parameters peak current (Pc), pulse-on time (Pon), and gap voltage (Vg) on the material removal rate (MRR), tool wear rate (TWR), machining time (MT), surface roughness (SR), taper angle (TA), and overcut (OC). The selected process parameters were Pc from 8 to 14 A, Pon from 60 to 90 μs, and Vg from 20 to 80 V respectively. The parametric assessment was performed based on the objectives of maximizing the MRR and minimizing the TWR, MT, SR, TA, and OC. The effect of process parameters on various output responses was summarized. From the experimentation, MRR is significantly affected by Vg, and maximum MRR is found at the high levels of Pc and Pon. Reduced TWR was observed at the 2nd level of Pc (0.058 mm3 min−1) and 4th level of Vg (0.076 mm3 min−1) and this same factor has more influence on MT. High level of Pc and Pon exhibits maximum TWR with erosion. The results show that Pon time relatively gives low SR (2.36 μm) and minimum OC (0.0015 mm) was achieved at a high level of Vg. Few un-drilled holes with cracks were witnessed due to high TWR. Many drilled holes exhibit < 2° of TA which indicates good dimensional accuracy.

The ground-state mass excess of the

drip-line nucleus

Al is measured for the first time as

keV using the newly-developed B
ρ-defined isochronous mass spectrometry method at the cooler storage ring in Lanzhou. The new mass excess value allowed us to determine the excitation energies of the two low-lying

states in

Al with significantly reduced uncertainties of 51 keV. When compared to the analogue states in its mirror nucleus

F, the mirror energy differences of the two

states in the

Al-

F mirror pair are determined to be

keV and

keV. The excitation energies and mirror energy differences are used to test the state-of-the-art ab initio valence-space in-medium similarity renormalization group calculations with four sets of interactions derived from the chiral effective field theory. The mechanism leading to the large mirror energy differences is investigated and attributed to the occupation of the

orbital.
A dual source switched-capacitors multilevel inverter topology with extended voltage levels and voltage gain
Authors: Al-Tameemi Weam , Babaei Ebrahim , Sabahi Mehran
Published: January 2024

The switched-capacitors multi-level inverters (SCMLI) are widely used in renewable energy resources for enhancing the quality and reliability of generated power. This paper suggests a new topology of extendable voltage levels and voltage gain units using switched capacitors SC with a dual DC source. The proposed unit can be extended by a modular pattern to increase the output voltage levels and voltage-boosting gain of the inverter. The main feature of this work is presenting a unit topology that utilizes multiple and modular sub-cells to increase the voltage gain at the output by increasing the number of the sub-cell components. A ternary relationship of the voltage magnitudes between the two asymmetrical DC sources is mandatory. Furthermore, all the capacitors are self-balanced, so there is no need for any additional and complex control circuit. Moreover, to decrease the cost factor of the inverter, a low IGBT switch count is taken into consideration and no passive diodes are used in the proposed structure. The H-bridge is connected to the unit to achieve bipolar voltage at the output. The operational analysis of the inverter is delineated in detail. A comparative study with state-of-art MLIs in different terms such as the number of components, the total standing voltage, the cost factor, and the gain shows the particularity of the proposed topology. The simulation of the proposed MLI is performed using PSCAD-EMTDC software. An experimental prototype is built to validate the simulation results.
Deep kernel methods learn better: from cards to process optimization

Published: January 2024

The ability of deep learning methods to perform classification and regression tasks relies heavily on their capacity to uncover manifolds in high-dimensional data spaces and project them into low-dimensional representation spaces. In this study, we investigate the structure and character of the manifolds generated by classical variational autoencoder (VAE) approaches and deep kernel learning (DKL). In the former case, the structure of the latent space is determined by the properties of the input data alone, while in the latter, the latent manifold forms as a result of an active learning process that balances the data distribution and target functionalities. We show that DKL with active learning can produce a more compact and smooth latent space which is more conducive to optimization compared to previously reported methods, such as the VAE. We demonstrate this behavior using a simple cards dataset and extend it to the optimization of domain-generated trajectories in physical systems. Our findings suggest that latent manifolds constructed through active learning have a more beneficial structure for optimization problems, especially in feature-rich target-poor scenarios that are common in domain sciences, such as materials synthesis, energy storage, and molecular discovery. The Jupyter Notebooks that encapsulate the complete analysis accompany the article.

Using this notion, we compute the automorphism group of the polarized Hodge structure of certain Klein hypersurfaces that we call of Wagstaff type, which are characterized by the existence of an automorphism of large prime order. For cubic hypersurfaces and some other values of

The recruitment of ACF1 and SMARCA5 to DNA lesions relies on ADP-ribosylation dependent chromatin unfolding

Published: January 2024

ADP-ribosylation signaling orchestrates the recruitment of various repair actors and chromatin remodeling processes promoting access to lesions during the early stages of the DNA damage response. The chromatin remodeler complex ACF, composed of the ATPase subunit SMARCA5/SNF2H and the cofactor ACF1/BAZ1A, is among the factors that accumulate at DNA lesions in an ADP-ribosylation dependent manner. In this work, we show that each subunit of the ACF complex accumulates to DNA breaks independently from its partner. Furthermore, we demonstrate that the recruitment of SMARCA5 and ACF1 to sites of damage is not due to direct binding to the ADP-ribose moieties but due to facilitated DNA binding at relaxed ADP-ribosylated chromatin. Therefore, our work provides new insights regarding the mechanisms underlying the timely accumulation of ACF1 and SMARCA5 to DNA lesions, where they contribute to efficient DNA damage resolution.
