Authors: Biggs Elizabeth E. , Therrien Michelle C. S. , Abarca Diana , Romano Mollie , Barton-Hulsey Andrea , Collins Sara C.
Published: January 2024

Purpose:

Family–professional partnerships are important for youth learning to use aided augmentative and alternative communication (AAC). This study examined the family-oriented beliefs and practices of speech-language pathologists (SLPs) working with preschool and school-aged children learning to use aided AAC (aged 3–21 years), specifically during the COVID-19 pandemic.

Method:

Participants were 25 SLPs who participated in an individual semistructured interview. Qualitative analysis was used to identify and describe groups of SLPs based on commonalities and differences in their beliefs and practices working with families. The characteristics of SLPs in each group was also explored descriptively (e.g., race/ethnicity, work setting, caseload).

Results:

SLPs clustered into three groups based on their beliefs and practices: (a) professionally centered, (b) family-allied, and (c) family-focused. SLPs varied across these groups in how they planned services, offered training/coaching, communicated, shared resources, offered emotional support, and adapted to and with different families.

Conclusions:

Findings indicate the need to support greater family-centeredness in AAC services by building on the strengths of SLPs in the field. Promoting strong family–professional partnerships could in turn improve outcomes for students who use AAC.

Prediction of dissolved gas content in transformer oil based on multi‐information fusion
Authors: Yang Tongliang , Fang Yun , Zhang Chengming , Tang Chao , Hu Dong
Published: January 2024

In order to accurately predict the content and variation trend of dissolved gas in transformer oil and guide the condition maintenance of power transformers, a combined prediction model based on multi‐information fusion is proposed and its effectiveness is analysed. First of all, based on the possibility of pathological and missing historical sample data, a detection and filling method based on variable weight combination samples is established. Second, the authors propose two models. Aiming at the non‐linear and non‐stationary characteristics of gas content, a univariate decomposition prediction mode HBA‐VMD‐TCN which based on the Honey Badger algorithm, variational mode decomposition and time convolutional network (TCN) is established. Then the multivariate Informer prediction model is established for gas content affected by multiple variables. Third, the cross‐entropy theory is used to determine the weight coefficients of the two models, and the multi‐information fusion combined prediction model is formed. Finally, on the basis of the above, a method to determine the time step and the position information of the transition point adaptively in the process of prediction is proposed to further improve the prediction accuracy. The results show that, through a series of simulation experiments of model comparison and transformer anomaly prediction, the accuracy and effectiveness of the combined prediction model are verified.
High step up DC–DC converter with low conduction losses and reduced switching losses
Authors: Akhlaghi Zahra , Karimi Amirhossein , Adib Ehsan
Published: January 2024

This article presents a novel high step up converter based on the active switch inductor (ASL) technique for renewable energy source applications. The coupled inductor technique provides an opportunity to increase the gain. The proposed converter exploited the leakage inductors to provide zero current switching (ZCS) turn‐on for both switches. Therefore, there is no need for an auxiliary circuit, which simplifies the structure. Also, all diodes turn off under ZCS, which eliminates the reverse recovery problem and results in reduced switching losses. The energy of the leakage inductor is recycled, and the voltage spike on the switches is limited. In addition, all semiconductor voltage stresses are clamped below the output voltage. Hence, components with lower on‐resistance can be utilized to reduce conduction loss. Because of the reduction in power loss, the efficiency rises to 97.2% at 250 W output power. It also benefits from the current sharing of the interleaved structure. The operating principles, design considerations, and comparison to other topologies are discussed. To verify the effectiveness of the proposed converter, a prototype converter with 250 W of output power, 50 V of input voltage, 500 V of output voltage, and 100 kHz of switching frequency is implemented.
A proposed method for calculating the voltage and current distributions of grounded and isolated networks subjected to line‐to‐ground faults
Authors: Gouda Ossama. E. , Dein Adel Z. El , Mbasso Wulfran F. , Alharthi Mosleh , Ghoneim Sherif S. M.
Published: January 2024

One crucial objective of this article is to present simplified and accurate approaches to study the current distribution and ground surface potential around the area surrounding an earthed and isolated system in case of a line‐to‐earth fault. The present study is done in the case of uniform and two‐layer soils. Suggested models for calculating the distribution of the earth's surface current density, step, and touch voltages in grounded and isolated systems are presented, discussed, and adapted. The contact and arc resistances of line to ground faulty conductors are considered. Rods and/or grounding grids usually do grounded systems. The impact of both step and touch potentials and current density are investigated in this article. The methods of the calculations are based on the electrical concepts, the charge simulation method, and the imaging procedure for the grounding system. The suggested method can be considered a novel and simple technique for calculating the current distributions of the ground surface during line to ground fault. The results agree with those obtained by others, with the advantage of the proposed algorithm for its ease of application and simplicity. 3‐D dimensions’ contours of the current density and the electric potential on the earth surface around the faulty point are presented in case of homogeneous and two layers’ soil. Finally, this article's novelty is to devise a method for calculating the step and touch potentials and current density around the point of contact of the conductor carrying the electric voltages in the event of faults occurring in the electrical network, whether the network is grounded or isolated. Such faults of electrical networks may cause human hazards.
Efficient simulation of stochastic interactions among representative Monte Carlo particles
Authors: Beutel M. , Dullemond C. P. , Strzodka R.
Published: January 2024

Context. Interaction processes between discrete particles are often modelled with stochastic methods such as the Representative Particle Monte Carlo (RPMC) method which simulate mutual interactions (e.g. chemical reactions, collisions, gravitational stirring) only for a representative subset of n particles instead of all N particles in the system. However, in the traditionally employed computational scheme the memory requirements and the simulation runtime scale quadratically with the number of representative particles.

Aims. We want to develop a computational scheme that has significantly lower memory requirements and computational costs than the traditional scheme, so that highly resolved simulations with stochastic processes such as the RPMC method become feasible.

Results. In this paper we propose the bucketing scheme, a hybrid sampling scheme that groups similar particles together and combines rejection sampling with a coarsened variant of the traditional discrete inverse transform sampling. For a v-partite bucket grouping, the storage requirements scale with n and v2, and the computational cost per fixed time increment scales with n ⋅ v, both thus being much less sensitive to the number of representative particles n. Extensive performance testing demonstrates the higher efficiency and the favourable scaling characteristics of the bucketing scheme compared to the traditional approach, while being statistically equivalent and not introducing any new requirements or approximations. With this improvement, the RPMC method can be efficiently applied not only with very high resolution but also in scenarios where the number of representative particles increases over time, and the simulation of high-frequency interactions (such as gravitational stirring) as a Monte Carlo process becomes viable.
Bayesian deep learning for cosmic volumes with modified gravity
Authors: García-Farieta Jorge Enrique , Hortúa Héctor J. , Kitaura Francisco-Shu
Published: January 2024

Context. The new generation of galaxy surveys will provide unprecedented data that will allow us to test gravity deviations at cosmological scales at a much higher precision than could be achieved previously. A robust cosmological analysis of the large-scale structure demands exploiting the nonlinear information encoded in the cosmic web. Machine-learning techniques provide these tools, but no a priori assessment of the uncertainties.

Aims. We extract cosmological parameters from modified gravity (MG) simulations through deep neural networks that include uncertainty estimations.

Methods. We implemented Bayesian neural networks (BNNs) with an enriched approximate posterior distribution considering two cases: the first case with a single Bayesian last layer (BLL), and the other case with Bayesian layers at all levels (FullB). We trained both BNNs with real-space density fields and power spectra from a suite of 2000 dark matter-only particle-mesh N-body simulations including MG models relying on MG-PICOLA, covering 256 h−1 Mpc side cubical volumes with 1283 particles.

Results. BNNs excel in accurately predicting parameters for Ωm and σ8 and their respective correlation with the MG parameter. Furthermore, we find that BNNs yield well-calibrated uncertainty estimates that overcome the over- and under-estimation issues in traditional neural networks. The MG parameter leads to a significant degeneracy, and σ8 might be one possible explanation of the poor MG predictions. Ignoring MG, we obtain a deviation of the relative errors in Ωm and σ8 by 30% at least. Moreover, we report consistent results from the density field and power spectrum analysis and comparable results between BLL and FullB experiments. This halved the computing time. This work contributes to preparing the path for extracting cosmological parameters from complete small cosmic volumes towards the highly nonlinear regime.
Probing the statistical isotropy of the universe with Planck data of the cosmic microwave background
Authors: Kester C. E. , Bernui A. , Hipólito-Ricaldi W. S.
Published: January 2024

Aims. We study the angular distribution of temperature fluctuations in the cosmic microwave background (CMB) to probe the statistical isotropy of the universe by using precise full-sky CMB data with a model-independent approach.

Methods. We investigated the temperature-temperature angular correlations in the four Planck foreground-cleaned CMB maps that were released recently. We performed a directional analysis on the CMB sphere to search directions in which the temperature-temperature angular correlations are extreme.

Results. Our analyses confirm a preferred axis in the CMB sphere, pointing in the direction (l, b)≃(260° ,130° ), at the 98%−99% confidence level. In this direction, the CMB angular correlations exceed the antipodal direction most strongly. This preferred direction is unexpected in the ΛCDM cosmological model and represents a significant deviation from results obtained by applying the same procedure to simulated statistically isotropic CMB maps. This result confirms the north-south asymmetry in the most recent Planck data. This phenomenon is one of the previously reported CMB anomalies.

Conclusions. We performed a robust detection of the north-south asymmetry in the temperature-temperature angular correlations, with a slightly different statistical significance, in the four Planck foreground-cleaned CMB maps. Moreover, we performed consistency tests by adding foreground and noise, both Planck data products, to the CMB map we studied, and we also investigated and discarded possible bias in our method. After these detailed analyses, we conclude that the north-south asymmetry phenomenon is present with a high statistical significance in the Planck CMB maps we studied. This result confirms previous reports in the literature in the past 20 years.
Formation of the Trappist-1 system in a dry protoplanetary disk
Authors: Schneeberger Antoine , Mousis Olivier , Deleuil Magali , Lunine Jonathan I.
Published: January 2024

A key feature of the Trappist-1 system is its monotonic decrease in bulk density with growing distance from the central star, which indicates an ice mass fraction that is zero in the innermost planets, b and c, and about 10% in planets d through h. Previous studies suggest that the density gradient of this system could be due to the growth of planets from icy planetesimals that progressively lost their volatile content during their inward drift through the protoplanetary disk. Here we investigate the alternative possibility that the planets formed in a dry protoplanetary disk populated with pebbles made of phyllosilicates, a class of hydrated minerals with a water fraction possibly exceeding 10 wt%. We show that the dehydration of these minerals in the inner regions of the disk and the outward diffusion of the released vapor up to the ice-line location allow the condensation of ice onto grains. Pebbles with water mass fractions consistent with those of planets d–h would have formed at the snow-line location. In contrast, planets b and c would have been accreted from drier material in regions closer to the star than the phyllosilicate dehydration line.
Thermal and kinetic coronal rain diagnostics with Mg II h & k lines
Authors: Kriginsky M. , Oliver R.
Published: January 2024

Aims. The aim of this work is to assess the temperature and velocity diagnostics of coronal rain clumps, as observed in the lines formed in the upper chromosphere.

Methods. We performed the temperature diagnostics using inversions of data from nine spectroscopic observations obtained with the IRIS spectrograph in the Mg II h & k lines. The sensitivity to the temperature of the emission peaks of these lines was exploited to determine the temperature of the coronal rain plasma using inversions of the spectroscopic profiles. Additional relationships between different spectral features of these lines, derived from the use of 3D radiative transfer line synthesis applied to simulations, were employed in order to derive the line-of-sight (LoS) velocities in different parts of the coronal rain plasma.

Results. For the first time, spectroscopic inversions of coronal rain were successfully performed. Temperatures derived from the inversions yield coronal rain clump temperatures at the formation height of the emission peaks of the Mg II h & k lines in the range between 5000 and 7000 K. This narrow range of values remains consistent among all the different observations used in this work. We obtained LoS velocities of up to 40 km s−1, which are consistent with the motion of the plasma being mostly constrained to the plane of the sky, as the coronal rain was mostly detected shortly after its formation and the observations took place in the disc. Furthermore, velocity diagnostics led to the detection of larger velocities at higher layers of the coronal rain plasma in some cases. This increased velocity seems to indicate that at some point (at least) during the fall of coronal rain clumps towards the chromosphere, the material in the upper part of the coronal rain plasma is falling with greater velocity than the material below it. The conditions of the temperature and density of the coronal rain plasma where the Mg II h line forms appear to be slightly different that those of the Mg II k line, with the former found at slightly colder and denser parts of the plasma.
Probability-of-failure-based optimization for random PDEs through concentration-of-measure inequalities
Authors: Ortigosa-Martinez Rogelio , Martinez-Frutos Jesus , Periago Francisco
Published: January 2024

Control and optimization problems constrained by partial differential equations (PDEs) with random input data and that incorporate probabilities of failure in their formulations are numerically extremely challenging, since the computational cost of estimating the tails of a probability distribution is prohibitive in many situations encountered in real-life engineering problems. In addition, probabilities of failure are often discontinuous and include huge flat regions where gradients vanish. Based on the McDiarmid concentration-of-measure inequality, this paper proposes a new functional which provides a tight and smooth bound for the probability of a given random functional of exceeding a prescribed threshold parameter. Hence, this approach relieves the above-mentioned difficulties in the case where the solution map is convex with respect to the random parameter, as in the case of a deterministic differential operator and the random parameter appearing linearly in the right-hand side term. Well-posedness of the corresponding optimal control problem is established and the viability of the proposed method is numerically illustrated by two benchmarks examples arising in topology optimization and optimal control theory.

Published: January 2024

An uptick in student enrollment at UIN Raden Intan Lampung has led to a correlated surge in vehicular activity, amplifying existing challenges related to auditory pollution that could interfere with educational activities. This study aims to explore the interrelationship between the density of vehicular flow and ambient noise levels within the campus of UIN Raden Intan Lampung while also assessing whether the observed noise levels transgress the thresholds established by environmental guidelines. A quantitative, descriptive methodology has been adopted for this investigation. Data points concerning both the volume of vehicles and corresponding noise levels were collected at diverse locations across the campus over multiple weekdays. The data reveals that Thursdays experience the highest vehicular flow with a count of 648 vehicles per hour. In contrast, Mondays witness the least, recorded at 344 Veh/Hour. Noise levels peak at 73.33 dB on Thursdays and dip to their lowest at 67.92 dB on Mondays. Ultimately, the campus of UIN Raden Intan Lampung has noise levels that breach the acceptable limits as dictated by the 1996 Ministerial Decree on Environmental Affairs, which specifies a 55 dB limit for educational settings. These results highlight the urgency for targeted intervention and mitigation approaches to minimize the adverse acoustic impact on the scholastic community.

Authors: Sari Delima Palwa , Darwito Purwadi Agus
Published: January 2024

Unmanned aerial vehicles (UAVs) can either be flown autonomously or remotely by a pilot. Due to its many benefits, including the capacity to take off and land vertically and the ability to take off and land in a small space, this form of UAV quadcopter is currently the subject of extensive research. An autonomous UAV is being developed to reduce the likelihood of pilot operating errors when managing the UAV. The quadcopter dynamic system in this study was controlled primarily by a radial basis function neural network (RBFNN), and its performance was evaluated using simulation on a test track with outside disturbances. One test track is used for the simulation, and there are no outside disturbances. Input of external noise occurs concurrently for x, y, and z coordinates. The average of error for the control system SMC and SMC-RBFNN without disturbance is 0 according to the simulation results. Additionally, the SMC control system’s of error with external disturbances is 0.74, whereas it is 0.54 for the SMC-RBFNN control system. This is demonstrated by the system’s ability to return to the test track at the present within 9 seconds while employing the SMC-RBFNN controller. In contrast, the system can reach the test track in 18 seconds while using the SMC. The SMC- RBFNN is one of the suitable control strategies for flight missions with external disturbances, it may be inferred.

Published: January 2024

In 2020, Indonesia generated 67.8 million tons of waste, with organic waste accounting for 60% of the total, particularly food waste. Food waste is a severe problem, particularly in large cities such as Jakarta, where food waste accounts for around 70% of total waste. Poorly managed food surpluses are at the core of the problem, resulting in food waste and greenhouse gas emissions. The Ruang Pangan community in Bandar Lampung is one of several food banks that provide surplus food to disadvantaged communities and orphanages. They created apps like MifsApps to help partners distribute surplus to the community. The app connects food donors and recipients, reducing edible food waste. The app’s mechanism is similar to food rescue, except it provides easy access to surplus information. The app enables members of the Ruang Pangan Community to view surplus data, respond to deliveries, and report on food distribution documents. MifsApps promotes SDGs 2 and 12 (Zero Hunger and Responsible Consumption and Production). The app helps to reduce social inequality and poverty, improve people’s welfare, and promote responsible production and consumption. MifsApps, as a technical breakthrough, is a real-world application for fulfilling the SDGs holistically.

Analysis, Design, Development, Implementation, and Evaluation (ADDIE) is the development paradigm employed in this study technique. This research was conducted on junior high school students in Serang, Banten province, Indonesia. The subjects of this study consisted of 40 students aged 13 years, consisting of 20 male students and 20 female students. The results showed that the responses from mathematics teachers who taught Geometry to augmented reality learning media showed an average result of 85. So it can be said that augmented reality media is very feasible to be used as a Geometry learning medium. The results of the student response test obtained an average score of 84. Students were interested in using this augmented reality learning media in Geometry learning activities. Furthermore, the effectiveness test results show that learning geometry using augmented reality is effective. In addition, it is effective because using the augmented reality application allows students to see reality and immediately imagine the results of their learning. Augmented reality helps students visualize abstract concepts to understand and structure course material more effectively.
Risk perception among workers exposed to ionizing radiation: a qualitative view
Authors: Rincón G. , González Y. , Sánchez C.
Published: January 2024

Ionizing radiation is energy in wave or particle form that can be absorbed by occupationally exposed professionals. With exposure, diseases may occur as defined by the International Agency for Research on Cancer Working Group on the Evaluation of Carcinogenic Risks to Humans 2000. Therefore, identifying hazards, assessing risks, and evaluating experiences of the involved parties, available resources, and work processes is necessary. We analysed risk perception compared with the pillars of radiological protection (justification/optimization/limitation) and the principles of distance/time/shielding. We used qualitative methodology under the phenomenological paradigm to assess participants perceptions regarding the ionizing radiation risk using conversational interviews. The data collection period was 2019–2020. The interpretative work was conducted by thematizing interviews, which were categorised and schematized for analysis. The practices of five participants with at least 20 years of experience in radiation use were explored. Five categories were identified. We found that the ‘As Low As Reasonably Achievable’ principle was recognised based on distance/time/shielding and according to the International Atomic Energy Agency (IAEA) and Bonn Call for Action. The justification associated with the risk/benefit was not associated with the fear of being wrong, with the understanding that, according to the IAEA, 30% of procedures are not justified.

Die ersten Generalisten haben im Frühjahr 2023 ihren Abschluss gemacht. Die neuen Pflegefachfrauen und -männer haben jedoch anders gelernt. Da sich das Berufsbild der Pflege und damit der Fokus der Ausbildung verändert hat, bedarf es auch einer neuen Form des Berufseinstiegs – auch und gerade für den Bereich der Pädiatrie.

Computational models of evolution are valuable for understanding the dynamics of sequence variation, to infer phylogenetic relationships or potential evolutionary pathways and for biomedical and industrial applications. Despite these benefits, few have validated their propensities to generate outputs with in vivo functionality, which would enhance their value as accurate and interpretable evolutionary algorithms. We demonstrate the power of epistasis inferred from natural protein families to evolve sequence variants in an algorithm we developed called sequence evolution with epistatic contributions (SEEC). Utilizing the Hamiltonian of the joint probability of sequences in the family as fitness metric, we sampled and experimentally tested for in vivo

TEM-1 variants. These evolved proteins can have dozens of mutations dispersed across the structure while preserving sites essential for both catalysis and interactions. Remarkably, these variants retain family-like functionality while being more active than their wild-type predecessor. We found that depending on the inference method used to generate the epistatic constraints, different parameters simulate diverse selection strengths. Under weaker selection, local Hamiltonian fluctuations reliably predict relative changes to variant fitness, recapitulating neutral evolution. SEEC has the potential to explore the dynamics of neofunctionalization, characterize viral fitness landscapes, and facilitate vaccine development.
Multiscale biophysical analysis of nucleolus disassembly during mitosis

During cell division, precise and regulated distribution of cellular material between daughter cells is a critical step and is governed by complex biochemical and biophysical mechanisms. To achieve this, membraneless organelles and condensates often require complete disassembly during mitosis. The biophysical principles governing the disassembly of condensates remain poorly understood. Here, we used a physical biology approach to study how physical and material properties of the nucleolus, a prominent nuclear membraneless organelle in eukaryotic cells, change during mitosis and across different scales. We found that nucleolus disassembly proceeds continuously through two distinct phases with a slow and reversible preparatory phase followed by a rapid irreversible phase that was concurrent with the nuclear envelope breakdown. We measured microscopic properties of nucleolar material including effective diffusion rates and binding affinities as well as key macroscopic properties of surface tension and bending rigidity. By incorporating these measurements into the framework of critical phenomena, we found evidence that near mitosis surface tension displays a power-law behavior as a function of biochemically modulated interaction strength. This two-step disassembly mechanism maintains structural and functional stability of nucleolus while enabling its rapid and efficient disassembly in response to cell cycle cues.
Crash modules to help Persians speak more intelligible and comprehensible English, emphasizing either production or
perception of either sounds or melodies
Authors: van Heuven Vincent J. , Yenkimaleki Mahmood
Published: January 2024

Yenkimaleki and van Heuven (2021) studied the effects of teaching
either segmental or suprasegmental (prosodic) aspects of English, in combination with either perception or production-focused
practice (four combinations in all) on the speech intelligibility and comprehensibility of Persian L1 learners of English as a
foreign language. Generally, production-focused exercises were more effective but there was no overall effect of teaching
segmentals versus prosody. However, the specific combination of emphasis on prosody and production-oriented exercises was most
beneficial. We summarize the results of the study and present, more systematically and in more detail than in the original
article, the materials and teaching methods used.
Student understanding of the Bloch sphere

Published: January 2024

Quantum information science is a rapidly growing interdisciplinary field that is attracting the attention of academics and industry experts alike. It requires talent from a wide variety of traditional fields, including physics, engineering, chemistry, and computer science, to name a few. To prepare students for such opportunities, it is important to give them a strong foundation in the basics of quantum information science, in which quantum computing plays a central role. In this study, we discuss the development, validation, and evaluation of a tutorial on the Bloch sphere, a useful visual tool for developing intuition about single quantum bits (qubits), which are the basic building block of any quantum computer. Students’ understanding was evaluated after they received traditional lecture-based instruction on the requisite topics, and again after engaging with the tutorial. We observe, analyze, and discuss their improvement in performance on concepts covered in the tutorial.

Novel platforms interfacing trapped cold atoms and guided light in nanoscale waveguides are a promising route to achieve a regime of strong coupling between light and atoms in single pass, with applications to quantum non-linear optics and quantum simulation. A strong challenge for the experimental development of this emerging waveguide-QED field of research is to combine facilitated optical access for atom transport, atom trapping via guided modes and robustness to inherent nanofabrication imperfections. In this endeavor, here we propose to interface Rubidium atoms with a photonic-crystal waveguide based on a large-index GaInP slab. With a specifically tailored half-W1 design, we show that a large chiral coupling to the waveguide can be obtained and guided modes can be used to form two-color dipole traps for atoms down to 115 nm from the edge of the structure. This optimized device should greatly improve the level of experimental control and facilitate the atom integration.
