High-resolution organ dosimetry for human exposure to low-frequency electric fields

Evaluation of the fields induced in the human body, provides a means of quantification of various exposures to low-frequency electric and magnetic fields. A new hybrid numerical method is used to compute these quantities, generated in an anatomically-based high-resolution human body model, by low-frequency uniform electric fields. The hybrid method combines scalar-potential finite-difference and quasistatic finite-difference time-domain methods, and is capable of accurately computing the induced fields in a full-body model composed of 1 736 872 cubic voxels with 3.6-mm edges. Results specific to various organs are given for exposure to 60-Hz fields, with the body model in three positions relative to a ground-plane. The effect of tissue conductivity is investigated. The data presented can be linearly scaled to frequencies up to 100 kHz without appreciable error; provided that changes of tissue conductivity with frequency are taken into account. Evaluations such as the present one should prove useful in the development of protection standards, and are also expected to aid in the understanding of results from various animal and tissue culture studies.
Predicting Student Dropout in Self-Paced MOOC Course Using Random Forest Model

A significant problem in Massive Open Online Courses (MOOCs) is the high rate of student dropout in these courses. An effective student dropout prediction model of MOOC courses can identify the factors responsible and provide insight on how to initiate interventions to increase student success in a MOOC. Different features and various approaches are available for the prediction of student dropout in MOOC courses. In this paper, the data derived from a self-paced math course, College Algebra and Problem Solving, offered on the MOOC platform Open edX partnering with Arizona State University (ASU) from 2016 to 2020 is considered. This paper presents a model to predict the dropout of students from a MOOC course given a set of features engineered from student daily learning progress. The Random Forest Model technique in Machine Learning (ML) is used in the prediction and is evaluated using validation metrics including accuracy, precision, recall, F1-score, Area Under the Curve (AUC), and Receiver Operating Characteristic (ROC) curve. The model developed can predict the dropout or continuation of students on any given day in the MOOC course with an accuracy of 87.5%, AUC of 94.5%, precision of 88%, recall of 87.5%, and F1-score of 87.5%, respectively. The contributing features and interactions were explained using Shapely values for the prediction of the model.
Critical dimension measurements by electron and optical beams for the establishment of linewidth standards

To establish traceability in sub-micrometer critical dimension measurements, a silicon reference artifact was manufactured. The measurement characteristics of the artifacts were examined by simulation and a metrological scanning electron microscope system. The possibility of linewidth indication by a peak-to-peak definition for isolated lines is described, and a pitch reference by a silicon grating was examined. A simulation based on a diffusion theory is described to predict the edge signal for the electron beam line scan on the artifact. It predicted narrower linewidth for isolated lines and showed good agreement with experimentally obtained critical dimensions. <<ETX>>
Optimal capacitor allocation in distribution systems using a genetic algorithm and a fast energy loss computation technique

This paper presents a new approach to shunt capacitor placement in distribution systems having customers with different load patterns. The allocation of capacitors is considered in a system comprising a network of feeders fed from an upstream equivalent transmission system through a substation transformer. The benefits of capacitor placement, such as the system capacity release and reduction of overall power and energy losses, are considered. The fast method of total energy loss calculation based on the computation of the moments of normalized daily load curves is used to calculate the annual energy loss reduction. An example of optimal capacitor allocation in a distribution system is presented in which customers with commercial, urban residential, rural and light industrial load patterns are considered.
Framing basic income in Australia: how the media is shaping the debate

ABSTRACT Universal basic income is an old idea that has experienced a surge in global attention. In many countries, it is creeping up the policy agenda as an alternative to traditional welfare. Yet, in Australia, the idea is mostly ignored by the two main political parties. Communication scholars have long contended that the media play a role in influencing opinion and setting the policy agenda. Using a framing approach, this study analyses how basic income was framed in 2018 by seven Australian newspapers and compares the results with those in countries where basic income has solidified a position in public discourse. We found that the mainstream media outlets in Australia are overtly hostile to the idea, which presents a significant obstacle to a universal basic income gaining legitimacy as a social policy.
Cranial Base Angle in Patients With Cleft Lip and Palate—A Systematic Review and Meta-Analysis

Background: Diverse findings have been reported for the cranial base angle (CBA) in patients with CLP (cleft lip and palate) and non-CLP controls. Objective: The aim of this study is to assess and evaluate the CBA in patients with CLP and non-CLP controls. Methods: Data from PubMed, OVID Technologies, Inc., Cochrane, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Scopus, Web of Science, and EMBASE for Excerpta Medica dataBASE (EMBASE) with relevant terms was extracted until December 31, 2020. Inclusion criteria were data of patients with non-syndromic unilateral cleft lip and palate (UCLP) and bilateral cleft lip and palate (BCLP). In the case of UCLP and BCLP, patients with craniofacial syndromes were excluded. The study proposal was registered with PROSPERO (Registration number: CRD42021228632). Results: Fifteen studies with a total of 2032 participants were included for the systematic review and 14 studies with a total of 1972 participants were included for the meta-analysis. The risk of bias was assessed using the Modified Newcastle Ottawa scale under seven domains by two authors. Thirteen studies were graded as “good” and two as “satisfactory. ” The CBA in patients with CLP were greater than the non CLP Class I controls in six of the 15 studies. CBA was greater in patients with CLP than non-CLP controls by 1.21° (95% CI of 0.19-2.22). Meta-analysis reported considerable heterogeneity (I2 = 86%). Anterior (ACB) and posterior cranial base (PCB) lengths were shorter in patients with CLP than in the non-cleft Class I controls by 2.14 mm (95% CI of 0.99-3.30) and 2.06 mm (95% CI of 1.52-2.60), respectively. Conclusion: Most studies were graded as good. Patients with CLP had greater CBA and shorter ACB and PCB lengths when compared to non-CLP controls.
Relationships among Language Proficiency, Communication Patterns, and Safety Performance in Small Work Crews in the United States

AbstractThe construction industry employs approximately 6% of all U.S. workers but accounts for over 16% of all occupational fatalities. Recent statistics indicate that over 40% of all U.S. construction laborers cannot speak English proficiently. To ensure strong safety performance, it is vital to include every individual in a construction crew in safety-related communications, regardless of language proficiency. Considering that most safety communication is delivered in English, it is not surprising that Spanish-speaking construction workers are fatally injured at a disproportionate rate. To conduct the first exploration of the characteristics of strong, multilingual safety networks in the Denver Metropolitan region of the United States, a multilingual research team conducted interviews with the members of 14 construction crews. Demographic attribute data for each individual (e.g., language proficiency, years of experience, position in the company) and network data were collected to analyze the safety co.
A Lightweight Authenticated Key Agreement Protocol Using Fog Nodes in Social Internet of Vehicles

Recently, there has been rapid growth in the Internet of things, the Internet of vehicles, fog computing, and social Internet of vehicles SIoV , which can generate large amounts of real-time data. Now, researchers have begun applying fog computing to the SIoV to reduce the computing pressure on cloud servers. However, there are still security challenges in SIoV . In this paper, we propose a lightweight and authenticated key agreement protocol based on fog nodes in SIoV . The protocol completes the mutual authentication between entities and generates the session key for subsequent communication. Through a formal analysis of the Burrows–Abadi–Needham (BAN) logic, real-oracle random (ROR) model, and ProVerif, the security, validity, and correctness of the proposed protocol are demonstrated. In addition, informal security analysis shows that our proposed protocol can resist known security attacks. We also evaluate the performance of the proposed protocol and show that it achieves better performance in terms of computing power and communication cost.
Differences in Pulmonary Function among Croatian Premier League Soccer and Futsal Players

The purpose of this study was to compare pulmonary function of Croatian premier league soccer and futsal players. 52 soccer players and 56 futsal players performed forced expiratory manoeuvres into a portable spirometer. Measurements included forced vital capacity (FVC), forced expiratory flows at 50%FVC (FEF50) and 25%FVC (FEF25), forced expiratory volume within the first second (FEV1), Tiffeneau index (FEV1/%FVC) and maximum voluntary ventilation (MVV). The analysis of spirometry indicators differences between Croatian futsal and soccer players indicated that the soccer players had statistically significantly higher values in the FVC, FEV1, FEV50 and MVV variables, in relation to the futsal players. The differences of training and competition process in Croatian soccer and futsal players most likely caused the obtained differences of lung functions.
Surface Reflectance Distributions and their Effect on Average Daylight Factor Values in Atrium Buildings

The aim of this research was to study parametrically the effect of different distribution patterns of atrium wall reflectances on average daylight factor (ADF) values in the well of a square, four-sided, top-lit atrium model that was placed inside an artificial sky. The artificial sky replicated the luminance distribution of a CIE overcast sky. To achieve the variability in reflection distribution the atrium surfaces were painted in alternating bands of white and black horizontal stripes. For each of the experiments the widths of these bands were altered but the overall split between white and black bands was always maintained at 50 % white and 50% black. Experiments were also conducted for atrium wall surfaces painted all black (0% wall reflectance) and all white (100% wall reflectance). This study was able to investigate the impact on ADF values in atria of more realistic distributions of light reflecting surfaces. Results from the study showed that the ADF values on the floor of the atrium, compared to the standard calculated ADF, were affected by the reflectance distributions of the atrium surfaces. Wide bands of different reflectances displayed the largest variations. For narrow bands the different reflectance distributions did not affect the ADF levels as much. The results of this study demonstrate the importance of the reflective properties of the atrium surfaces and the variations in reflectance distributions on the daylight reaching the atrium floor.
Establishment of culture and microinjection methods for false clownfish embryos without parental care

Anemonefish, including the false clownfish Amphiprion ocellaris, are attractive model organisms because of their unique features, such as sex change and brilliant color patterns in mutants. However, anemonefish are not widely used to study gene function using reverse genetic approaches owing to microinjection difficulties and subsequent rearing and hatching of embryos without parental care. A. ocellaris embryos are spawned on a hard substrate and cared for by their parents until hatching. However, the eggs need to be detached from the substrate and raised without their parents to perform successful microinjection. We established a method to culture and hatch A. ocellaris embryos without spawning substrates or parental care. We found that changing water and generating water flow are critical for culturing the embryos, and that water flow (as physical stimulation) and complete darkness in the dark period are necessary for successful hatching. We further investigated the effectiveness of microinjection into the yolk sac of fertilized eggs rather than into the cytoplasm, which makes microinjection easier. A reporter RNA injected into the yolk sac was transferred to the cytoplasm and translated, indicating that yolk sac microinjection is an efficient alternative as has been used for zebrafish. These findings highlight the potential of A. ocellaris as an experimental model organism for reverse genetics, and our methods could be applied to other anemonefish species.
Effects of Plateau Air Quality and Low Oxygen Content on Platelet mtDNA Methylation and High Altitude Pulmonary Edema

In 2020, the monitored AQI (Air Quality Index) in plateau — Tibet varied from 24 to 98 and averaged 48, while the PM 2.5 concentration ranged between 3.0 and 31 µ g m –3 and with an average of 10 µ g m –3 . The plateau — Tibet, had a good air quality, but with a lower atmospheric pressure and low oxygen concentration. As the important characteristic of plateau atmospheric environment, hypobaric hypoxia (HBH) is the key risk factor causing high altitude pulmonary edema (HAPE). It has been reported that the abnormal platelet function caused by HBH is an important pathogenesis of HAPE. In this preliminary study, male Sprague-Dawley rats were randomly divided into control group and HBH 24, 48, and 72-hour exposed groups. A multi-functional hypoxic chamber was used to simulate HAPE model with an altitude of 6000 m, oxygen concentration of 9.46% and partial oxygen pressure of 9.6 KPa. We measured pulmonary wet to dry (W/D) weight ratio, MT-Cox 1, MT-Cox 2 and MT-Cox 3 methylation levels by pyrosequencing on blood samples from all rats and the levels of plasma inflammatory mediators by Luminex liquid chip technology. Results showed that the W/D ratio increased in the HBH-48h and HBH-72h exposed groups significantly (p < 0.05). The mtDNA methylation levels in all HBH exposed groups were lower than pre-exposure (all p value < 0.05). The levels of MT-Cox 1, MT-Cox 2_Pos2 and MT-Cox 2_Pos3 methylation were correlated with W/D ratio significantly (r = 0.16–0.20, p < 0.05). And a strong correlation was found between some inflammatory cytokines (IL 4, IL 6, IL 10 and IL 12p70) and MT-Cox 2 methylation levels (r = 0.09–0.30, p < 0.05). In conclusion, HBH exposures can induce alterations in platelet mtDNA methylation in HAPE, which may be related to unfavorable effects on HAPE caused by the inflammation through the regulation of inflammatory response.
Fully passivated W-band InAlAs/InGaAs/InP monolithic low noise amplifiers

The development of W-band monolithic low noise amplifiers (LNAs) using a fully passivated 0.1 /spl mu/m pseudomorphic InAlAs/InGaAs/InP low noise HEMT technology is presented. Both wafer passivation and stabilisation bakes have been introduced, for the first time, to the InP HEMT MMIC process to make it more suitable for production. A three-stage single-ended 94 GHz monolithic LNA shows a measured noise figure of 3.3 dB and 20 dB associated gain. A measured noise figure of 2.3 dB is achieved for a single-stage MMIC LNA at 94 GHz. These results represent state-of-the-art performance of HEMT MMIC LNAs at this frequency. The effects due to SiN passivation for both HEMT device and circuit performance are also addressed.
Collective individualism: the informal and emergent dynamics of practising safety in a high‐risk work environment

Safety knowledge appears to be ‘a doing’. In construction work safety is practised in the complex interrelationship between the individual, pair and gang. Thus the aim is to explore the nature and scope of individualist and collectivist preferences pertaining to the practice of safety at a construction site. An ethnographic fieldwork, in which the researcher worked as an apprentice, will provide detailed and experience‐near insights into the complexity of these processes. Findings show that individualist and collectivist preferences influence the amount of risk the individual worker will assume and expose workmates to. Aspects such as self‐regulation, self‐confidence and independence are acceptable values only to the extent that they do not pose a threat to the solidarity of the community or safety of other workers. The informal practice of safety is a tight‐rope act that involves balancing the form and scope of these preferences.
Load and Displacement Prediction for Shakedown Analysis of Layered Pavements

A complete shakedown assessment of pavement behavior under repeated loading requires a shakedown load analysis as well as a displacement evaluation. Both load and displacement bounding calculations at shakedown are presented, and the pavement subjected to repeated loading is analyzed as a plane strain problem. The proposed shakedown load formulation is verified by using numerical results for a homogeneous isotropic half space. To illustrate the relevance of the numerical formulations, the numerically determined residual stresses are compared with available experimental data. The variation of shakedown loads with different material properties for two-layered pavements is investigated in detail. The results of permanent displacement bounds are presented and compared with the displacement finite element calculation. Simple design charts for the layered pavements are presented.
Design of probe-fed stacked patches

In this paper, a design strategy to achieve bandwidths in excess of 25% for probe-fed stacked patches is presented. The choice of appropriate dielectric materials for such bandwidths is given and the role of each antenna parameter in controlling the impedance behavior is provided. It has been found that the selection of the substrate below the lower patch plays a major role in producing broad-band responses. A simple design procedure is outlined and this technique is verified experimentally. The findings presented here can be applied to all types of probe-fed stacked patches as well as edge-fed and cavity-backed configurations.
An Evaluation of the Teaching Practice Curriculum in Light of the Standards-Based Evaluation Model 1

This study was conducted to identify standards related to the objectives, content, learning-teaching process, evaluation, practice teacher and university practice teacher dimensions of the teaching practice curriculum and their actualization level in light of the standards-based evaluation model. The study follows the singular descriptive model and its population comprises practicing teacher candidates and university practice teachers from education faculties located in the Eastern and Southeastern Turkish provinces of Elazig, Erzincan, Erzurum, Diyarbakir, Malatya and Agri, and practice teachers working at Directorates of National Education in these provinces. The "simple random sampling method" was used in the study and 1,392 of the 2,075 individuals in the population were included in the sample. A 95-item scale was designed by the researchers to be used as the data collection tool. After completing the several stages of the scale development process, a pilot study was conducted on 312 candidate teachers using the draft scale consisting of 134 draft standards. The pilot study showed that the reliability coefficients of the study were Cronbach Alpha=. 979, Bartlett= 59501.482 (p=0.000 and df= 17955) and Kaiser-Meyer-Olkin (KMO)=. 850 and the load factor values of the scale was over . 45. In addition, the test retest, parallel test and split half test reliability analyses of the scale were also made. The data were analyzed by using frequency and percentage, arithmetic mean, and standard deviation techniques. As a result of the study, a total of 95 standards were identified, 16 of which were in the objectives dimension, 15 in the content dimension, 14 in the learning-teaching process dimension, 14 in the evaluation dimension, 18 in the practice dimension, and 18 in the practice teacher dimension. It was also found that the standards in the objectives, content, evaluation and university practice teacher dimensions were actualized "Partially", while those in the learning-teaching process and practice teacher dimensions were actualized "Fairly". © 2013 IOJES.

Speech Reconstruction With Reminiscent Sound Via Visual Voice Memory

The goal of this work is to reconstruct speech from silent video, in both speaker dependent and independent ways. Unlike previous works that have been mostly restricted to a speaker dependent setting, we propose Visual Voice memory to restore essential auditory information to generate proper speech from different speakers and even unseen speakers. The proposed memory takes additional auditory information that corresponds to the input face movements and stores the auditory contexts that can be recalled by the given input visual features. Specifically, the Visual Voice memory contains value and key memory slots, where value memory slots are for saving the audio features, and key memory slots are for storing the visual features in the same location of the saved audio features. Guiding each memory to properly save each feature, the model can adequately produce the speech. Hence, our method employs both video and audio information during training time but does not require any additional auditory input during inference. Our key contributions are: (1) proposing the Visual Voice memory that brings rich information of audio that complements the visual features, thus producing high-quality speech from silent video, and (2) enabling multi-speaker and unseen speaker training by memorizing auditory features and the corresponding visual features. We validate the proposed framework on GRID and Lip2Wav datasets and show that our method surpasses the performance of previous works on both multi-speaker and speaker independent settings. We also demonstrate that the Visual Voice memory contains meaningful information to reconstruct speech.
