A Systematic Review of Publications Using the Dundee Ready Education Environment Measure (DREEM) to Monitor Education in Medical Colleges in Saudi Arabia

Background This systematic review aimed to identify and evaluate publications using the Dundee Ready Educational Environment Measure (DREEM) and its domains, genders, and educational level (EL) to monitor the education environment in medical colleges (MCs), applied medical science colleges (AMSCs), and dental colleges (DCs) in Saudi Arabia (SA). Material/Methods A literature search was performed using PubMed, ScienceDirect, Scopus, Wiley Library, and Web of Science database keywords and medical, applied medical science, dental colleges headings, followed by a summary and analysis of results. We included all related studies that used DREEM as a tool and were published up to 2022. The following information was extracted from the included studies: researcher’s name(s), publication year, overall DREEM, domain, gender, and educational levels. Results Among the 40 studies included in this review, 25 papers were conducted in medical colleges, 5 in applied medical science, and 10 in dental colleges. Overall, DREEM scores among all involved colleges were “more positive than negative,” with scores between 101 and 150. In relation to the 5 domains of DREEM, the percentages of medical colleges ranged from 75% to 88% for all domains, whereas it was higher in dental (80% to 90%) in most domains, but considerably lower for applied medical science (50% to 75%). Females had higher DREEM values in dental than medical and applied medical science colleges, whereas educational levels were higher in applied medical science colleges. Conclusions Overall, DREEM scores were more positive than negative and moved in the correct direction among all involved colleges, with varying degrees of significance between genders and educational levels.
Diffraction of Surface Plasmon Modes on Abruptly Terminated Metallic Nanowires

Surface plasmon polariton modes on cylindrical nanowires remain accessible for applications even when the wire radius is only a small fraction of the wavelength. Abrupt wire termination constitutes a basic discontinuity that underlies many of the wire functions. The diffraction of the surface plasmon modes by the discontinuity is investigated. The near field around the termination plane is determined with no simplifying assumptions of the physical aspects of the diffraction process. The transmitted and reflected fields are calculated for wires in vacuum. Full conversion of the surface plasmon mode energy into light is shown to occur at specific values of the wire radius.
Detection of Printed Circuit Board Defects on ENIG and ENIPIG Surface Finishes with Convolutional Neural Networks and Evaluation of Training Parameters

Increasingly high demands are being placed on the quality inspection of printed circuit boards (PCBs). A full surface inspection of all produced PCBs and a high defect detection accuracy of the inspection system are becoming prerequisites for an efficient quality management. At the same time, the demand for PCBs is constantly increasing over the years due to the high demand for electrical devices. Human inspection is no longer feasible due to the high production rates and required defect detection accuracy. Therefore, automatic inspection systems are increasingly used for quality control in the various process steps of PCB production. In this article, the first automatic inspection system for detecting defects on Electroless Nickel Immersion Gold (ENIG) and Electroless Nickel Immersion Palladium Immersion Gold (ENIPIG) surfaces is presented. A pretrained convolutional neural network (CNN) and the sliding window approach are used. A training dataset consisting of six different defect types and an OK class containing only defect-free PCB images was labeled for this classification problem. The hyperparameters learning rate and batch size are varied for different training runs of the CNN, and the performance of the network in PCB defect detection is evaluated using a test dataset. The true-positive rate, truenegative rate, and F1-score were analyzed for the evaluation. Our results show that the best performances could be achieved at low batch sizes and low learning rates.
New Insights into the Crystal Chemistry of FeB-Type Compounds: The Case of CeGe

Several alkaline earth or rare earth binary monosilicides and -germanides possess complex bonding properties, such as polycation formation exceeding the scope of classical electron counting rules. In this study, we present characterization by powder and single-crystal diffraction and thermal analysis of CeGe, one of the few monogermanides crystallizing in the FeB-type structure. Comparative computational investigations for structure types experimentally observed for monogermanides and alternative structures with different structural motifs were performed to gain energetical insights into this family of compounds, underlining the preference for infinite germanium chains over other structural motifs. Formation enthalpy calculations and structural chemical analysis highlight the special position of FeB-type compounds among the monogermanides.
Bayesian Modeling and Forecasting of Intraday Electricity Load

The advent of wholesale electricity markets has brought renewed focus on intraday electricity load forecasting. This article proposes a multi-equation regression model with a diagonal first-order stationary vector autoregresson (VAR) for modeling and forecasting intraday electricity load. The correlation structure of the disturbances to the VAR and the appropriate subset of regressors are explored using Bayesian model selection methodology. The full spectrum of finite-sample inference is obtained using a Bayesian Markov chain Monte Carlo sampling scheme. This includes the predictive distribution of load and the distribution of the time and level of daily peak load, something that is difficult to obtain with other methods of inference. The method is applied to several multiequation models of half-hourly total system load in New South Wales, Australia. A detailed model based on 3 years of data reveals trend, seasonal, bivariate temperature/humidity, and serial correlation components that all vary intraday, justifying the assumption of a multiequation approach. Short-term forecasts from simple models highlight the gains that can be made if accurate temperature predictions are exploited. Bayesian predictive means for half-hourly load compare favorably with point forecasts obtained using iterated generalized least squares estimation of the same models.
A Bootstrap Revival of Some Nonparametric Distance Tests

Abstract Several tests based on the empirical measure have been proposed to test independence of variables, goodness of fit, equality of distributions, rotational invariance, and so forth. These tests have excellent power properties, but critical values are difficult, if not impossible, to obtain. Furthermore, these tests usually assume that the data are real-valued with continuous distributions. Here, critical values are determined by bootstrapping and the resulting tests are shown to have the correct asymptotic level under minimal assumptions. For example, given data Xi = (X i,1, …, Xi,d ), i = 1, …, n, it may be desired to test independence of the d components. The proposed test compares the empirical measure and the product of its marginals by taking a supremum over an appropriate Vapnik-Cervonenkis class of sets. No assumptions are made on the probability distribution of the data or on the space in which it lives; indeed, some components may be discrete, some continuous, and others categorical. Simil.
“We Think We’re Far from Conflict, but That’s Not True”: Peace Building and Remembrance through Memory Sites in Colombia

Although memory sites and formal schooling both serve as battlegrounds for postconflict disputes over memory, there is a dearth of research that examines the connection between the two. This article draws on the case of Colombia to explore the use of memory sites, such as museums and memorials, as pedagogical tools in education for peace building. Through observations of school visits to the Centro de Memoria, Paz y Reconciliación (Center for Memory, Peace, and Reconciliation) and interviews with students, I highlight the potential that memory sites have for establishing a sense of closeness in students’ understanding of conflict. I conceptualize closeness across three axes: familiarity, temporality, and spatiality. In bringing students closer to the history of the armed conflict, memory sites hold the potential to transmit a sense of responsibility toward peace building. This research adds to our understanding of the construction, transmission, and contestation of collective memories of violence.
Relationship between Dough Properties and Baking Performance of Panned Bread: The Function of Maltodextrins and Natural Gums

The effectiveness of hydrocolloids (2% maximum in various combinations) from various sources, including maltodextrins (MD) with polymerization degree (DP) 18 and ziziphus gum (ZG), on the dough properties and quality of panned bread, as well as the possibility of using them to delay the bread staling process, have been investigated after 24, 72, and 96 h of storage. By evaluating the pasting capabilities of wheat flour slurry, dough properties, and the final product, the effects of the ziziphus gum (ZG) and maltodextrins (MD) were ascertained. A TA-TXT texture analyzer, a texture profile analysis test, and Micro-doughLab were used to evaluate the dough mixing properties. Additionally, a hedonic sensory evaluation of the overall acceptance of the bread, as well as its texture, aroma, taste, and color, was done. It is clear that MD had a more distinct impact than ZG on the way dough was mixed, the texture of the gel, and the finished product. The combination of MD and ZG significantly altered the bread’s physical characteristics and its aging over time. The decreased peak viscosity and noticeably smaller setback of wheat flour gels, which corresponded to lower gel hardness, serve as evidence of reduced amylose retrogradation. At 2%, MD outperformed ZG in terms of increasing water absorption, dough stability, and bread loaf volume. With the exception of the blend that included three times as much MD as ZG, all mixes, including the control, exhibited an increase in bread firmness as a function of time after storage. Overall, the panelists liked (score of 5 and above) the bread made with mixes that had either MD or ZG, or a combination of both.
Asymptotics for censored regression quantiles

It has been difficult to generalise Kaplan–Meier approaches to censored regression data under the minimal condition that censoring and response are conditionally independent given the explanatory variables. Portnoy [S. Portnoy, Censored regression quantiles, J. Am. Stat. Assoc. 98 (2003), pp. 1001–1012. ] provided such a generalisation based on the paradigm of censored quantile regression. However, previous research has only provided consistency results for this approach. The results here provide an asymptotic distribution theory under relatively mild conditions for a gridded version of the algorithm in Portnoy [S. Portnoy, Censored regression quantiles, J. Am. Stat. Assoc. 98 (2003), pp. 1001–1012. ], and show that the asymptotics for censored regression quantiles are an exact generalisation of those for the Kaplan–Meier estimator in one sample.
Factors Associated with the Low Immunization Coverage in the Second Year of Life in the Central Region of Burkina Faso

Introduction: The second year of life immunization is the administration of vaccines to a child between 12 and 24 months of age. After seven years of implementation of this immunization, the coverage remains low. This study was to understand the factors associated with low immunization coverage in the second year of life in Burkina Faso. Methods: The LQAS method was used to conduct a cross-sectional household survey of children aged 24 to 35 months in two health districts in the Central region. A two-level random sampling was used. Eighteen health facilities were randomly selected and then in each health facility, 1 to 4 villages were randomly selected for the study. The households were visited to collect the data. In the selected health facilities, the EPI manager and health facilities manager were questioned about vaccination during the second year of life. Results: Forgetting to vaccinate the child (25.1%), lack of time to go to health facilities on immunization day (23.3%), long waiting time in health facilities (11.0%) and far distance from the health facilities (11.0%) are the reasons given by mothers whose children did not receive MR2. Multiparous mothers were vaccinated with MR2 than Primiparous mothers (aOR = 2.4 et CI 95%=1.5 – 4.0). According to health workers, the main reasons were the lack of vaccine in 29.6% of cases and that there were not enough children to open 10 doses vial of the vaccine in 18.5% of cases. Conclusion: Targeted interventions are needed to address these contributing factors to poor immunization coverage.
Experimental investigations of cavitation-bubble collapse in the neighbourhood of a solid boundary

Cavitation bubbles were produced by focusing giant pulses of a Q-switched ruby laser into distilled water. The dynamics of the bubbles in the neighbourhood of a solid boundary were studied by means of high-speed photography using a rotating-mirror camera with framing rates of up to 300000 frame/s. Bubble motion was evaluated from the frames with the aid of a digital computer using a graphical input device. Smoothed distance-time curves of different portions of the bubble wall were obtained also, allowing a reliable calculation of bubble-wall velocities (except at the actual instant of collapse). One of the numerical examples of the collapse of a spherical bubble near a plane solid boundary obtained by Plesset & Chapman could be realized experimentally. A comparison of the bubble shapes shows good agreement.
Surgical outcomes and factors associated with postoperative complications of colorectal cancer in a Colombian Caribbean population: Results from a regional referral hospital

Colorectal cancer is the most common malignant neoplasm of the gastrointestinal tract. Its incidence and mortality vary markedly at a global level. Assessing the epidemiological behavior of this condition allows reevaluating diagnostic, therapeutic and prognostic options, based on new findings. In Colombia, few studies have correlated variables associated with surgical and oncological outcomes in this type of cancer. Then, the aim of this study was to evaluate the surgical outcomes and factors associated with postoperative complications of colorectal cancer in a Colombian Caribbean Population.
Relationship Between Family Caregiver Burden and Medication Adherence in Patients with Mechanical Valve Replacement: A Structural Equation Model

Background Oral anticoagulant is a necessary long-term treatment after mechanical valve replacement (MVR), and medication adherence has a great impact on patients with MVR. Although family caregiver burden is negatively correlated with medication adherence, little is known about the underlying mechanism. Purpose To test whether family caregiver burden influences medication adherence through post-traumatic growth or medication literacy in patients with MVR. Patients and Methods A total of 206 patients after MVR were included in this cross-sectional study from July 2021 to December 2021. Data regarding medication adherence, family caregiver burden, post-traumatic growth, and medication literacy were collected by questionnaires. Data were analyzed through SPSS, and pathway analysis was conducted by using AMOS, based on the bootstrapping method. Results Post-traumatic growth was positively associated with medication adherence (r = 0.284, P < 0.05). Post-traumatic growth independently mediated the association of family caregiver burden on medication adherence [β = 0.32, 95% confidence intervals: (−0.016, −0.008)]. The mediated effect value for post-traumatic growth was 0.07, accounting for 24.14% of the total effect. The model’s fit indices were adequate. Conclusion The mediating effect of post-traumatic growth between family caregiver burden and medication adherence existed in patients with MVR. Interventions considering post-traumatic growth may be useful to increase medication adherence and improve patient rehabilitation.
Sound generated by instability waves of supersonic flows. Part 2. Axisymmetric jets

A solution describing the spatial evolution of small-amplitude instability waves and their associated sound field of axisymmetric supersonic jets is found using the method of matched asymptotic expansions (see Part 1, Tam & Burton 1984). The inherent axisymmetry of the problem allows the instability waves to be decomposed into azimuthal wave modes. In addition, it is found that because of the cylindrical geometry of the problem the gauge functions of the inner expansion, unlike the case of two-dimensional mixing layers, are no longer just powers of ε. Instead they contain logarithmic terms. To test the validity of the theory, numerical results of the solution are compared with the experimental measurements of Troutt (1978) and Troutt & McLaughlin (1982). Two series of comparisons at Strouhal numbers 0.2 and 0.4 for a Mach-number 2.1 cold supersonic jet are made. The data compared include hot-wire measurements of the axial distribution of root-mean-squared jet centreline mass-velocity fluctuations and radial and axial distributions of near-field pressure-level contours measured by microphones. The former is used to test the accuracy of the inner (or instability-wave) solution. The latter is used to verify the correctness of the outer solution. Very favourable overall agreements between the calculated results and the experimental measurements are found. These very favourable agreements strongly suggest that the method of solution developed in Part 1 paper is indeed valid. Furthermore, they also offer concrete support to the proposition made previously by a number of investigators that instability waves are important noise sources in supersonic jets.
A Transfer-in-Pieces Consideration of the Perception of Structure in the Transfer of Learning

Many approaches to the transfer problem argue that transfer depends on the recognition of the same or similar abstract structure in 2 different situations. However, mainstream cognitive perspectives and contrasting Piagetian constructivist accounts differ in their conceptualizations of structure. These differences, not clearly articulated in the literature, have significant implications for accounts of transfer. Using interview data involving undergraduates learning elementary principles of probability and statistics, and Wagner's (2006) transfer-in-pieces perspective, I extend existing constructivist accounts of transfer in at least 2 ways. First, I show how the notion of a concept projection (diSessa & Wagner, 2005; Wagner, 2006) reveals fine-grained mechanisms of transfer that demonstrate how people structure situations and that elaborate on the Piagetian processes of assimilation and accommodation. Second, I examine how what experts consider a single mathematical concept or principle may come to be recognized through a variety of assimilatory cognitive resources whose usefulness is influenced by contextual factors. That is, an individual might structure 2 contextually dissimilar situations differently while perceiving the same mathematical principle at work in both. Similarly, 2 or more individuals may agree on the relevance of a particular mathematical concept in a situation, even though each structures the situation differently.
Wavelength dependence of photoelectron spectra in above-threshold ionization

We present angle- and energy-resolved measurements of photoelectrons produced in strong-field ionization of Xe and Ar using a tunable femtosecond laser in the wavelength range between 600 and 800 nm. Systematic analysis of the experimental data that are quantitatively reproduced by numerical solutions of the time-dependent Schrödinger equation with integration over the laser focal volume demonstrates the dominance of resonance-enhanced ionization. Continuous variation of the laser wavelength allows the identification of a number of consecutive channel-switching effects with a reliable assignment of the intermediate Rydberg states involved. The appearance of the resonant sub-structure in the electron energy spectra is influenced by the presence of a non-resonant contribution. At relatively low laser intensity, a coherent addition of resonant and non-resonant ionization processes is observed. Due to the absence of an intensity dependence in the resonance-enhanced ionization, we observe the persistence of Freeman resonances at the transition to the tunnelling regime.
Analysis of the Effect of Stock Prices on Coal Sub- Sector on the Indonesia Stock Exchange 2014-2019

The rise and fall of stock market prices in the capital market is an interesting phenomenon to discuss related to the issue of fluctuations in the value of the company itself. The performance of a company can be seen by looking at the financial statements. To measure the financial statements of a company can use financial ratios in a certain period. This study is to determine the effect of the Current Ratio, Debt To Equity Ratio, and Price Book Value on stock prices. The object of research is the coal sub-sector which is listed on the Indonesia Stock Exchange in 2014-2019. The research design used is causal research. The sampling technique was the purposive sampling method. The population in this study were 25 coal companies listed on the Indonesia Stock Exchange (IDX) in the 2014-2019 period as many as 8 companies met the criteria so that a total of 48 observations were used. The analysis technique used was panel data regression analysis and it was found that the higher model Appropriate use is a random effect. The data used in this study is secondary data. The results of this test indicate that simultaneously (Test F) Current Ratio, Debt to Equity Ratio and Price Book Value have a significant effect on stock prices. Partially (t-test) the Price Book Value variable has a significant positive effect on stock prices and the Debt to Equity Ratio variable has a significant negative effect on stock prices. Only the Current Ratio variable has no significant effect on the share price of coal sub-sector companies on the Indonesia Stock Exchange in 2014 – 2019.
Nonlinear Autopilot Design for an Asymmetric Missile Using Robust Backstepping Control

This paper deals with the design of a robust nonlinear controller for a highly maneuverable missile. Stabilization and tracking are achieved, exploiting a detailed nonlinear model of the six-degree-of-freedom, nonminimum phase, uncertain, and time-varying dynamics of a non-axial-symmetric air-to-air tail-controlled missile. A robust backstepping approach is applied to the multi-input/multi-output model to achieve both bank-to-turn and skid-to-turn maneuvers. Control objectives consist of following the reference signals in angle of attack, sideslip, and bank angle produced by the external guidance system, in order to pursue highly agile maneuvers. Uncertain terms, mostly due to aerodynamic coefficients and dynamic pressure, are suitably limited by bounding functions constructed using experience, a priori knowledge on system behavior, and a bit of conservatism. Robust sigmoidlike control functions are then used to dominate in size the uncertain terms. The whole control system is shown to be practically-robu.
