Authors: Anggrahita Hayuning , Guswandi Guswandi , Auni Ravidania
Published: November 2023

The rapid growth of cities, including Jakarta, encourages the conversion of non-built-up areas into built-up ones. It can threaten their sustainability. To overcome a decreasing trend of green open spaces, the Government of Jakarta (GoJ) has established a policy stipulating that urban areas must have at least 30% green open spaces. Therefore, the vertical residential complex can be a solution to reach it, especially in Simple and Low-Cost Apartment Buildings (Rusunawa). Based on previous issues, this paper analyses their surface and whether it reaches the regulation. Moreover, this paper identifies factors influencing the surface. We study 30 of 32 Rusunawas in Jakarta. Then, we conducted descriptive spatial analysis by interpreting high-resolution satellite imagery to find space utilization patterns in the Rusunawas. The findings are that: only 20 % of Rusunawas (6 of 30 Rusunawas) have reached a minimum of 30 % green open space of the total area, indicating challenges to meeting the regulation. Based on in-depth interviews with the management of Rusunawa, the findings are that: the land availability of Rusunawas' complex is limited, green open space competes with anthropogenic-living space use, and the initial site plan is not designed to meet the regulation. Moreover, in the case of Rusunawa located near the coastal area, water, and land salinity are obstacles.
Electronic Sick Leave Certificate on Telemedicine Service Implementation in Indonesia: A Legal Consideration
Authors: Budiyanti Rani Tiyas , Kusumastuti Wulan
Published: November 2023

Telemedicine service has been developed in Indonesia and its use has increased during the Coronavirus Disease 2019 (Covid-19) pandemic. This service makes it easier for people to get health services without meeting face-to-face. One of them is getting electronic medical certificates i.e. sick leave. However, problems arose regarding the legitimacy of electronic sick leave certificate (e-sick leave) through telemedicine services. This study aims to analyse the legal aspects of electronic sick leave in Indonesia. This research was normative research with statue and conceptual approach. Regulations in Indonesia have not discussed in detail the provision of electronic sick leave through telemedicine services. During the Covid-19 pandemic, Indonesian Medical Council Regulation Number 74 of 2020 was issued which permitted the issuance of sick certificates in telemedicine services with due observance of the principles of caution and high accountability. However it does not regulate in detail the provision of electronic sick leave through telemedicine services. Further regulations comprising of specific requirements and procedures are needed in Indonesia regarding telemedicine services, specifically in order to have valid electronic sick leave certificate issuance that can guarantee patient safety and accountability. Technological support is also needed to support the examination of patients in telemedicine services. Issuance of electronic sick leave requires collaboration between health care facilities and companies.

Assessing the Impact of Teachers' Training on Teaching HIV/AIDS Education in Schools in KwaZulu-Natal, South Africa
Authors: Ringisai Lovemote , Sutiningsih Dwi
Published: November 2023

School-based HIV/AIDS education is a common and well-proven intervention strategy for providing information on HIV/AIDS to young people in South African schools. However, lack of skills among teachers for imparting sensitive information to students can lead to program failure in terms of achieving goals. A cross-sectional study was conducted among teachers to identify the factors that support or hinder their role in HIV/AIDS education. A self-administered questionnaire was used for interviewing teachers from stratified randomly-selected 2 primary and 2 secondary schools in the province of KwaZulu-Natal’s Pietermaritzburg region. Out of the 4 selected schools, 2 are on an HIV/AIDS education intervention program under Community Care Project (NGO) while the other 2 selected schools are not (control). This was meant to compare the teachers’ ability, skill, and their participation in HIV/AIDS education between the intervention and control selected schools. Trained teachers in the intervention schools were more likely to participate, less likely to face difficulties, and more likely to use interactive teaching methods in HIV/AIDS classes compared to the controls who did not receive any training. Inadequate allocation of time for conducting the HIV/AIDS class was found to be barriers to HIV/AIDS education that suggest the need to provide teachers with more support in terms of training and logistics.

Published: November 2023

Le syndrome de Schwartz-Jampel (SJS, OMIM #255800) est une affection génétique ultra-rare définie par des manifestations myotoniques et des anomalies ostéo-articulaires. Transmis selon un mode autosomique récessif, sa prévalence est plus élevée dans les zones de forte endogamie. La découverte du gène HSPG2 codant une protéine de la lame basale a permis de mieux en délimiter les contours nosologiques. Le diagnostic est généralement très fortement suspecté cliniquement puis confirmé en biologie moléculaire. Le traitement reste à ce jour essentiellement symptomatique.

Published: November 2023

La sarcopénie est une maladie musculaire complexe liée à l’âge qui affecte entre 10 à 16 % des personnes âgées de plus 65 ans. Elle se caractérise par une perte excessive de la masse musculaire et de la force. Malgré la multitude d’études visant à comprendre les mécanismes physiologiques qui sous-tendent cette pathologie, la physiopathologie de la sarcopénie reste encore mal comprise. A ce jour, il n’existe pas de traitement pharmacologique pour lutter contre cette pathologie. Dans ce contexte, notre équipe développe des approches thérapeutiques basées sur l’utilisation de la protéine GDF5 pour contrecarrer la perte de la masse et de la fonction musculaire dans diverses conditions pathologiques dont la sarcopénie. Après avoir décrypté un des mécanismes moléculaires régulant l’expression du GDF5, nous avons démontré le potentiel thérapeutique de cette protéine dans la préservation de la masse et la force musculaire chez les souris âgées.
Histones méthyltransférases et myogenèse régénérative
Authors: Garcia Pauline , Le Grand Fabien
Published: November 2023

Le muscle strié squelettique adulte est composé de milliers de fibres (myofibres) capables de se contracter, permettant ainsi les mouvements volontaires. Après une lésion musculaire, les cellules souches musculaires localisées autour des myofibres s’activent, prolifèrent et se différencient pour former de nouvelles myofibres. Ces différentes étapes forment un processus appelé myogenèse. Cette dernière est rendue possible grâce à l’expression séquentielle de facteurs de transcription régulés par des facteurs épigénétiques qui agissent sur la chromatine afin de moduler l’expression génique et ainsi, le devenir de la cellule souche. Les histones méthyltransférases déposent des marques dites méthyl sur certaines histones afin d’induire la répression génique de régions spécifiques. Nous décrivons ici le rôle de SETDB1 au cours de la myogenèse adulte, et plus spécifiquement pendant la différenciation des cellules souches musculaires.
Réseau microtubulaire et fonctionnalité du muscle strié squelettique
Authors: Castellano Léa , Gache Vincent
Published: November 2023

Les muscles striés squelettiques sont constitués de cellules post-mitotiques et multinucléées : les fibres musculaires, dans lesquelles les noyaux sont régulièrement espacés et positionnés à leur périphérie. Ce positionnement spécifique des noyaux, nécessaire au bon fonctionnement du muscle, est essentiellement régulé par le réseau microtubulaire et ses partenaires protéiques. De nombreuses pathologies musculaires présentent une altération à la fois de l’organisation du réseau microtubulaire et du positionnement nucléaire, comme observé dans la Dystrophie Musculaire de Duchenne, les myopathies centronucléaires ou certaines maladies neuromusculaires. L’importance de l’interactome microtubulaire et son influence dans le maintien de l’homéostasie du muscle strié squelettique est un enjeu capital dans la compréhension des pathologies musculaires.

Fetal Autopsy—A Game Changer!
Authors: Elayedatt Rinshi Abid , Krishnan Vivek , Chandraprabha Vidya
Published: November 2023

Fetal autopsy is one of the most useful investigations that can change or significantly add to the clinical diagnosis despite a prenatal ultrasonographic diagnosis of a fetal abnormality. It is often required to determine the cause of intrauterine death or miscarriages, provide recurrence risk, and is known to alter the final diagnosis and genetic counseling in nearly half of the cases. This article reviews the role of fetal autopsy and discusses its contributory role in confirming the diagnosis and its usefulness in the genetic counseling of cases with risk of recurrence in future pregnancies.

Published: November 2023

Fetal meconium peritonitis (FMP) is a rare form of sterile chemical peritonitis occurring in utero due to the perforation of the fetal intestine, sometimes after fetoscopic laser photocoagulation (FLP) in twin-to-twin transfusion syndrome, with the broad spectrum of prenatal ultrasound manifestations including abdominal cyst. We report a unique presentation of FMP following FLP with ascites, pseudocyst formation, and the cyst resolving probably of a fistula formation. This case report highlights unusual FMP development and gives a novel clue to antenatal diagnosis and management.
Unusual Anterior Neck Swelling: Cervical Spinal Cord Schwannoma
Authors: Özgiray Erkin , Karagöz Cihat , Bölük Serdar , Balak Naci
Published: November 2023

Schwannomas are typically solitary, well-encapsulated, benign tumors running along or attached to a nerve. An intradural-extramedullary cervical spinal schwannoma, which first manifests as a swelling in the anterior neck, has not been reported to the best of our knowledge. We present the case of a 69-year-old patient complaining of a gradually worsening painful left cervical swelling for over 8 years. First, a posterior spinal midline approach was performed for the resection of the tumor and the tumor portion in the vertebral canal was totally removed. The second operation, the anterolateral approach, was planned to be executed in a second surgical session. The patient was discharged from the hospital without neurological deficits. Histopathological diagnosis was a schwannoma. The first aim of surgery is to treat neurological deficits in patients with cervical intraspinal schwannomas with/without extension into the extra-vertebral paravertebral neck regions. The surgical strategy combines the posterior midline and the anterolateral cervical approaches in the same session or at different times.
Smooth symmetric transonic isothermal flows with nonzero angular velocity
Authors: Zhang Na
Published: November 2023

In this paper, the steady inviscid flows with radial symmetry for the isothermal Euler system are studied in an annulus. We present a complete classification of transonic radially symmetric flow patterns in term of physical boundary conditions at the inner and outer circle. By solving the one side boundary problem, we obtain that there exist accelerating or decelerating smooth transonic flows in an annulus. Moreover, the structural stability of these smooth symmetric transonic flows with nonzero angular velocity are further investigated. Furthermore, we examine the transonic solutions with shocks as well via prescribing suitable boundary conditions on the inner and outer circle.
Progress in the preparation of high-quality wafer-scale monolayer and multilayer MS2 (M = Mo; W) films by CVD
Authors: Zhang Yangkun , Wang Boxin , Shi Dongxia , Zhang Guangyu
Published: November 2023

MS2 (M = Mo; W), with natural atomic thickness, are typical two-dimensional (2D) semiconductor materials, which have excellent electronic/optoelectronic properties and mechanical flexible properties. With the development of semiconductor device miniaturization, much attention has been brought to MS2, especially in large-scale integrated circuits, ultra-sensitive photodetectors, and flexible electronic devices. Here, we present the recent research progress on the controllable synthesis of high-quality, wafer-scale, uniform monolayer and multilayer MS2 films by chemical vapor deposition methods, focusing on the most concerning grain orientation control and defect modulation in whole wafer, besides the pursuit of more larger wafer size in MS2 films’ preparation. We also discuss some critical issues in the process of MS2 films growth and give a brief outlook in the controllable preparation of high-quality MS2 films for device application later on.
Raman spectrometry measurements for the 2D mapping of the degradation products on aged graphite anodes of cylindrical Li-ion battery cells
Authors: Jabri Slaheddine , Pitta Bauermann Luciana , Vetter Matthias
Published: November 2023

Here, Raman spectroscopy is shown to be a suitable method for post-mortem analysis to localize and identify degradation products on the surface of Li-ion battery electrode layers. Cylindrical battery cells are charged and discharged at 4° C for up to 250 cycles. The degradation products detected on the surface of graphite anodes are shown in 2D Raman mapping and discussed. The battery cells were cycled in an argon-filled glove box. The air-sensitive electrode layers were covered on both sides with coverslips transparent to the Raman laser to keep them without coming into contact with air during the measurements. The LiFePO4 cathode showed no detectable degradation during the aging process. The vibrations of lithium acetylide species (Li–C≡C–X) at 1850 cm−1 are used to detect lithium-containing degradation products on the surface of graphite anodes. Vibrational modes corresponding to polyacetylene at 1118 and 1497 cm−1 were observed for the first time on the aged graphite layers. The described analytical method and electrode preparation are particularly relevant for the identification and localization of degradation products on environmentally sensitive electrodes of Li-ion battery cells.
Numerical investigation of oblique detonation waves on a truncated cone in hydrogen–air mixtures
Authors: Zhou Lin , Tu Shengjia , Zhang Yining , Yang Pengfei , Teng Honghui
Published: November 2023

Traditional methods of initiating oblique detonation waves (ODWs) using wedges and cones face a fundamental challenge in reconciling the need for rapid initiation with stable combustion, especially at low flight Mach numbers (Ma < 8). This study introduces an innovative initiation configuration involving a truncated cone. By utilizing Euler equations coupled with detailed hydrogen–air chemical reaction models, the wave dynamics induced by the truncated cone configuration are systematically explored. The findings reveal that the truncated cone configuration enables more rapid initiation of ODWs compared to conventional cones, while also preserving improved stability when contrasted with wedge. This behavior can be attributed to the planar flow characteristics in the post-shock field of truncated cone, generated by the upstream wedge-shaped shock, and the Taylor–Maccoll flow characteristics, caused by the downstream conical shock. Furthermore, the study delves into the initiation and morphological changes with respect to the inner radius and angle of the truncated cone. As inner radii or truncated cone angle increase, three initiation wave systems emerge: stable, oscillatory, and detached modes. Analysis of the dynamic variations in pressure and velocity within the induction zone highlights that the upstream oscillation originates from the flow velocity in the induction zone falling below the local Chapman–Jouguet velocity of normal detonation wave (NDW). However, the upstream region of the truncated cone exhibits more pronounced expansion effects, leading to momentum loss, and subsequently, the weakening and even vanishing of the NDW. This prompts the downstream oscillation of the initiation structure, instigating a cyclic oscillation pattern.
The effect of porosity on flexoelectricity in 3D printed aluminum/polyvinylidene fluoride composites
Authors: Hafner Thomas A. , Örnek Metin , Collard Diane N. , Paral Mark W. , Son Steven F.
Published: November 2023

We investigated the relationship between porosity and flexoelectricity for aluminum (Al)/polyvinylidene fluoride (PVDF) composites. Neat PVDF, composites of micron aluminum (μAl)/PVDF, and composites of nano aluminum (nAl)/PVDF were 3D printed, and the flexoelectric response was measured using a cantilever beam test setup. Voids (up to 72.4 mm3) were incorporated into the samples by decreasing the infill percent of the 3D printed material. We found that increasing the porosity via millimeter scale voids incorporated into the infill pattern decreased the average effective flexoelectric coefficient relative to the near full-density (100% infill) control samples. This contrasts with other studies that have shown increasing micron scale porosity increases the flexoelectric coefficient. In addition, we measured higher flexoelectric responses for nAl/PVDF than μAl/PVDF as well as for samples printed by the Hyrel 3D SR printer as opposed to the Ender 3 V2 printer. These results indicate that charge generation due to flexoelectricity can be altered by changing parameters such as porosity, particle size of inclusions, or manufacturing method. Smaller voids and fine particles can induce larger strain gradients than larger inhomogeneities, leading to increased flexoelectric coefficients. A competing effect is that more porosity leads to less materials, which can decrease the flexoelectric coefficient.

Published: November 2023

The pachychilid genus Brotia H. Adams, 1866, distributed across South and South-East Asia, comprises 46 currently accepted species. Although Brotia has recently been revised, the systematic treatment of the Indian species requires further scrutiny. This study aims to resolve the phylogenetic relationships between Brotia species from north-east India and estimate the divergence using two mitochondrial markers, cytochrome c oxidase subunit I (COI) and 16S ribosomal RNA (16S). Species delimitation analyses have revealed six to nine distinct species in north-east India instead of the single currently known species. We confirm the monophyly of Brotia from the entire distributional range in South and South-East Asia and show that all Indian species form a single clade nested within the South-East Asian radiation. We conclude that Brotia has a South-East Asian origin, with two independent dispersals into India since the early Eocene and through the Oligocene, eventually splitting from ancestors during the late Cretaceous. Further integrative taxonomic research is needed to resolve the taxonomic status of the candidate species delineated herein and reveal the exact number of species in north-east India. This is the first phylogenetic analysis of Brotia from India, significantly improving our understanding of Indian freshwater gastropod fauna.
Mould contamination of dwellings after flooding

Published: November 2023

Australia’s sub-tropical coastline has been subjected to catastrophic flooding, congruent with a global trend of extreme weather events exacerbated by climate change. This study examined buildings post-flooding, to determine the impact of fungal contamination and evaluate remediation strategy success. Fungal species prevalence in association with wet building materials are outlined. Remediation methods found to be effective are highlighted. These findings support the necessity of establishing internationally recognised guidelines pertaining to mould contamination and remediation. This is particularly pertinent within the context of climate change. This research contributes to the scientific understanding of mycobiota in flood affected buildings, their health and safety implications and design of effective mitigation strategies.
Metaphorical extensions of the color term kaala ‘black’ in Hindi
Authors: Mishra Suneeta
Published: November 2023

This study explores the semantic and lexical extensions of the term for ‘black’ in Hindi by analyzing idiomatic expressions, compound words and culturally grounded metaphorical expressions from a cultural-cognitive perspective. The most commonly used Hindi term for black is kaala. The paper presents an analysis of 42 expressions with the term kaala (or its other morphological variants) in Hindi including idioms and compounds. The analysis finds that the color term extends to several experiential domains from emotions to morality and politics, usually signifying a negative aspect, but in some cases also a protection from negativity. It is found to be deep-rooted in Hindu mythology and grounds many a cultural belief. Several underlying metaphors are brought up by this analysis, many of which seem to be universal across languages, such as bad is black. But some metaphorical conceptualizations are found to be culture-specific, for instance the use of something black, like kaala tiika (black mark on the forehead or cheek), to counter the evil, and a goddess called kaali, said to have lethal powers. The analysis shows that the embodiment of human experience through the color ‘black’ has a substantial universal basis but at the same time, culture can lead to unique conceptualizations, as is the case with kaala.
Cultural models mediating between visual sensation and semiotic systems, exemplified on visual, alpha-pictorial and verbal-gestural communication
Authors: Brdar-Szabó Rita , Brdar Mario
Published: November 2023

People often see what they want to see (or hear, or taste, etc.), i.e., our mind imperceptibly edits our actual
sensations. Culture may function, metaphorically speaking, as a pair of glasses that filters light, because it may be tinted, or
have different lenses. In this article we study how visual sensations are filtered and edited, either reduced or enriched, so as
to produce perceptions fitting the cultural models we have, and how this interaction is reflected in semiotic systems, i.e., in
visual, multimodal, and verbal-gestural communication. Accordingly, we offer three case studies in which we demonstrate the claim
that variably articulated cultural models (often networks of related cultural models) we have influence whether, and how, we
experience something as being of metaphorical or metonymic nature.
A teacher-researcher snapshot of task-based peer interactions in EFL secondary school classrooms in
Germany
Authors: Kos Tomáš
Published: November 2023

This article reports a small classroom-based study that has explored task-based peer interactions among grade 9
secondary school students (N = 14) of middle and low relative proficiency. Drawing primarily on audio recordings
of peer interactions, oral presentations, and post-task interviews, and conducted by the teacher-researcher, it investigated how
students interacted on an output task that was embedded in regular EFL lessons and designed to wrap up the unit work centered
around the topic Down Under. A particular focus was on exploring to what extent and how students used the language that the task
was meant to trigger, namely future tense and unit-related vocabulary. The aim was to inquire whether the task worked in the way
it was designed for. The findings have shown that although students were involved with the task and with each other’s
contributions, the use of the targeted structure elicited by the task remained limited. Pedagogical implications are
discussed.
Scattered light monitoring system at the Virgo interferometer: performance improvement and automation based on O3 data
Authors: Longo Alessandro , Bianchi Stefano , Valdes Guillermo , Arnaud Nicolas , Plastino Wolfango
Published: November 2023

Scattered light, also referred to as scattering, is a nonlinear non stationary noise that can affect data acquired by ground-based laser interferometers for the detection of gravitational waves. A methodology for the identification and daily monitoring of scattering sources, based on the tvf-EMD algorithm, was applied to a large dataset of 132 days of data. Time series of the differential arm motion (DARM) degree of freedom acquired by the Virgo detector during the third LIGO-Virgo scientific run, so called O3, which lasted from 1 April 2019 to 27 March 2020, were considered. The analysis focused on correlation with suspended West end optical bench (SWEB) position data, as SWEB was a known culprit of scattering witnessed in DARM during O3. Different configurations were tested, improving performances with respect to previously obtained results and at the same time making the methodology fully automated. This allows to employ it as a monitoring system both during the phases of detector’s upgrade and in scientific runs such as the fourth scientific run, O4, currently scheduled to start on 2023. The higher values of correlation obtained suggest that tvf-EMD could improve the performance of scattered light noise subtraction from DARM.

Published: November 2023

We present the first empirical constraints on the polymer scale describing polymer quantized GWs propagating on a classical background. These constraints are determined from the polymer-induced deviation from the classically predicted propagation speed of GWs. We leverage posterior information on the propagation speed of GWs from two previously reported sources: (1) inter-detector arrival time delays for signals from the LIGO-Virgo Collaboration’s first gravitational-wave transient catalog, GWTC1, and (2) from arrival time delays between GW signal GW170817 and its associated gamma-ray burst GRB170817A. For pure-GW constraints, we find relatively uninformative combined constraints of

The proliferation of urbanization and the integration of new energy sources have stimulated the development of gas-insulated transmission lines and switchgear (GIL/GIS). In particular, the compact DC GIS in offshore converter platforms will significantly reduce footprints for DC switchyards, exhibit exceptional climatic resistance, and facilitate the cost-effective connection of remote offshore wind farms and submarine links. Nevertheless, insulators used in GIS/GIL always suffer from surface charge accumulation under DC stress, which could distort and enhance the local electric field and thus trigger a flashover at the gas–solid interface if it exceeds certain magnitude levels. This susceptibility becomes a major concern affecting the reliability of DC gas-insulated systems. Beyond these engineering-related challenges lie fundamental physics problems involving mechanisms of charge accumulation and charge-induced flashover which still require exploration. To this end, this paper presents an overview of recent advancements on this topic whilst highlighting relevant issues to be addressed. Specifically, the surface charge accumulation phenomena under DC fields are reviewed, and the charging mechanisms are summarized from macroscopic to microscopic perspectives. Further, the correlation between surface charge and surface flashover is discussed. Moreover, recent developments in tailoring methods for surface charging are also presented. Finally, perspectives are given on current research progress and future needs.

Photometry contributes to our understanding how the world is perceived by the human visual system, where a specific example is an early study of photographic plates. Nowadays photometry has an important role in measurement of lighting, particularly in the transition from incandescent lighting to LED lighting. In the context of sustainability and energy efficiency, updated photometric methods are needed that address the spectral, color, geometrical, and temporal characteristics of LED light sources. Highlights of the recent advances in these measurement methods are reviewed. Furthermore, challenges and achievements are described in the measurement of optical power, particularly related to the definition of the photometric SI base unit, the candela. These achievements are based on progress in the development of underpinning optical measurement standards, with a focus on technologies like the electrical substitution radiometer and the predictable quantum efficient detector. As a conclusion, the importance of ongoing research and development in photometry is emphasized considering its crucial role in supporting the advances of LED lighting technology and sustainable development goals of lighting industry.

Authors: Zheng Dongyao , Zhang Hui , Hu Fengxia , Shen Baogen , Sun Jirong , Zhao Weisheng
Published: November 2023

Oxide two-dimensional electron gas (2DEG) is a low-dimensional carrier system formed at the interface of oxide heterojunctions with strong and tunable Rashba spin–orbit coupling which makes oxide 2DEG an ideal platform for converting spin current and charge current. This review provides a summary of the recent advances on the 2DEGs at oxide interfaces for spin-charge interconversion. On one hand, we analyze properties and the efficiency of the spin-to-charge conversion through different ways of spin current injection. On the other hand, the conversion of charge current to spin current under different experimental methods has been summarized. These research achievements provide perspectives and methods for understanding and regulating the spin-charge interconversion of the 2DEG at the oxide interface.
Uniform approximation of 2D Navier-Stokes equations with vorticity creation by stochastic interacting particle systems
Authors: Grotto Francesco , Luongo Eliseo , Maurelli Mario
Published: November 2023

We consider a stochastic interacting particle system in a bounded domain with reflecting boundary, including creation of new particles on the boundary prescribed by a given source term. We show that such particle system approximates 2D Navier–Stokes equations in vorticity form and impermeable boundary, the creation of particles modeling vorticity creation at the boundary. Kernel smoothing, more specifically smoothing by means of the Neumann heat semigroup on the space domain, allows to establish uniform convergence of regularized empirical measures to (weak solutions of) Navier–Stokes equations.
Wave field synthesis using buckling dielectric elastomer transducers
Authors: Gareis Michael , Maas Jürgen
Published: November 2023

This work presents a wave field synthesis (WFS) system using a novel loudspeaker concept based on dielectric elastomers. In WFS, large numbers of densely packed, individual audio channels are controlled to recreate arbitrary acoustic scenarios in the listener space, (i.e. listener zones in a room where different audio content can be radiated in different directions from the array, as seen in the supplemental material). Spatial resolution of the system increases with the increasing number of audio channels and with decreasing loudspeaker spacing. This motivates the use of buckling dielectric elastomer transducers (BDETs) as loudspeakers, which feature a simple setup, rendering them extremely thin and lightweight, and which promises ease of manufacture through the low demand on resources. In this work, a WFS system featuring 480 BDET has been developed. The prototype includes software, electronics, and the loudspeaker array. The electronical and mechanical design of the system is presented in detail. A nonlinear model based on the third-order shear deformation theory is applied to the BDET; the BDET is then experimentally assessed and compared to the model. Further, the final loudspeaker array is characterized by directivity measurements in an anechoic room to validate the reproducibility and quality of the setup. The presented technology highlights the structural advantages of smart materials over conventional transducers, which often are too large, heavy, and expensive for such array applications.

Resilient Energy-to-peak Event-triggered Control of NCSs
Authors: Ji Yuxiang , Zhang Yu , Ma Xiaofeng , Li Xinling , Jiang Taiping
Published: November 2023

We address the resilient event-triggered energy-to-peak (RETEP) control problem of NCSs. The gain of the controller is impacted by uncertainty, and bound by a certain norm. By applying an appropriate Lyapunov function, we first propose a condition to ensure that the closed-loop NCS is asymptotically stable (AS) with a given energy-to-peak performance (EPP) index under zero initial conditions. Then, we present a design of the gain and trigger matrix of the needed RETEP controller. Finally, a simulation example is applied to validate the proposed controller RETEP control method.
A three-parameter interval number group decision-making method based on kernel and greyness degree
Authors: Wang Yan
Published: November 2023

A decision method based on kernel and greyness degree is proposed for group decision-making problems in which attribute values are represented by three-parameter interval grey numbers, whose kernel and greyness degree are modified. The prospect value of each program’s evaluation information given by decision-makers is solved by using prospect theory. Finally, the reasonable decision-makers weight should make the total weighted prospect value of the scheme the maximum, the deviation between the evaluation information of each decision-maker, the mean value of the evaluation information the minimum, and the greyness degree deviation value of the information which is given by decision makers the minimum. The weight vector of the decision-makers is obtained by solving this model, and the comprehensive prospect value of the solution is used to rank the alternatives. Finally, taking a commercial aircraft parts supplier selection as an example, the rationality of the method is verified.

In this paper, a landslide is used as the engineering background, and the FLAC3D software is used to analyze the stable state of the landslide. The relationship between the displacement and the time step of the point is analyzed. The position of the sliding surface is simulated, and the stable state of the landslide is comprehensively evaluated, thereby providing a meaningful experience for other similar projects.
Quantum-imaging detection of secondary neutrons in proton radiotherapy fields

Published: November 2023

Secondary radiation fields encountered in proton radiotherapy environments contain
different particle species produced in a broad range of energies and directions. Experimental
knowledge of the composition and spectral characteristics of such complex fields is valuable for
operation and protection of instruments and personnel, design and optimization of irradiations as
well as planning and validation of treatment plans. The neutron component, which are produced with
non-negligible yield, is in particular challenging to measure and discriminate from other
radiations by conventional detectors. In order to measure in such complex fields the neutron
component, both fast and thermal, we make use of the semiconductor pixel detector Timepix3
equipped with a silicon sensor and a neutron converter mask. The detector was before calibrated
with well-defined neutron fields. In this work, we characterize the secondary radiation field and
examine in particular the neutron component behind a large water-equivalent phantom irradiated by
a 190 MeV clinical proton beam. The detected neutrons have a predominant fast neutron
component. No thermal neutrons are observed in the measured data. The neutron-induced interactions
in the detector are resolved in a high background with enhanced discrimination by quantum-imaging
visualization, micrometer scale pattern recognition and high-resolution spectral-sensitive
tracking of single particles. Detailed results are provided in wide range in terms of composition
of the mixed-radiation field, total and partial fluxes and dose rates as well as particle
deposited dose and linear-energy-transfer (LET) spectra.
