Interrupted and uninterrupted lane changes: a microscopic outlook of lane-changing dynamics

Field observations suggest that the Lane-Changing (LC) processes are often interrupted by the surrounding vehicles. Understanding these intermediate interruptions and evasive behavior during an LC is necessary for developing realistic simulation tools, collision-warning systems, and human-like LC in self-driving vehicles. However, identifying and classifying LC into interrupted (ILC) and uninterrupted (ULC) is not straightforward. This study proposes a methodology for the automatic identification and classification of LC events. Further, we highlighted the characteristic differences between ILC and ULC by comparing their duration, crash likelihood, and driver discomfort. The likelihood, duration of exposure, and severity of LC crashes were captured using the surrogate safety measures such as Anticipated Collision Time (ACT), Time-Exposed ACT (TE-ACT), and Time-Integrated ACT (TI-ACT). The driver's discomfort was measured using acceleration noise and the number of sign inversions in the acceleration profile. The Kruskal–Wallis–ANOVA test on the above attributes and the sensitivity analysis of the duration models confirm that ILC and ULC are characteristically different.
Scour Characteristics and Equilibrium Scour Depth Prediction around Umbrella Suction Anchor Foundation under Random Waves

A series of numerical simulation were conducted to study the local scour around umbrella suction anchor foundation (USAF) under random waves. In this study, the validation was carried out firstly to verify the accuracy of the present model. Furthermore, the scour evolution and scour mechanism were analyzed respectively. In addition, two revised models were proposed to predict the equilibrium scour depth Seq around USAF. At last, a parametric study was carried out to study the effects of the Froude number Fr and Euler number Eu for the Seq. The results indicate that the present numerical model is accurate and reasonable for depicting the scour morphology under random waves. The revised Raaijmakers’s model shows good agreement with the simulating results of the present study when KCs,p < 8. The predicting results of the revised stochastic model are the most favorable for n = 10 when KCrms,a < 4. The higher Fr and Eu both lead to the more intensive horseshoe vortex and larger Seq.
Effect of Log Heat Treatment on Release of Growth Stresses in Eucalyptus Nitens

The use of Eucalyptus nitens has diversified the Chilean lumber industry in unprecedented ways. However, growth-induced strains cause splitting and warping. The objective of this investigation was to determine the effect of the heat treatment applied to logs of Eucalyptus niten s on the reduction of growth stresses and improvement of quality in sawn wood. Logs were extracted at different heights of the tree for 15-yr and 20-yr-old trees. The sawmill process was allowed to obtain radial, mixed, and tangential plane pieces, at two thicknesses (25 and 50 mm). The evaluation of MC and warping was according to Chilean National Standards. The results obtained in this research suggest that by applying the heat treatment to Eucalyptus nitens logs, a significant reduction in growth strains can be achieved. Heat treatment also increased the quality of the pieces in terms of bow, crooking, and twisting. Therefore, there are substantial benefits of using heat treatments to reduce defects caused by growth strains and thus increase the quality of the wood and reduce its warp.
The performance of solar cells using chlorophyll dye from Syzygium paniculatum

In this study, analysis was performed of the macro characterization of solar cells with chlorophyll dye from Syzygium paniculatum, using scanning electron microscopy (SEM) and energy-dispersive X-ray (EDX) analysis. Solar cells based on titanium dioxide (TiO2) nanomaterial and chlorophyll dye from S. paniculatum can increase efficiency due to flavonoids and batulinic acid content. Photoanode TiO2 is one of the essential factors determining the photovoltaic properties of dye-sensitized solar cells (DSSCs) and shade, which broadens the absorption spectrum. Furthermore, the method used in this research involved varying the colour of the S. paniculatum leaves, namely red (SP-Red), green (SP-Green) and a red–green mix (SP-Mix). From a macro analysis, SEM observations resulted in agglomerated and aggregated TiO2-polyethylene glycol (PEG)-dye layers with irregular shapes. EDX observation resulted in a peak in Ti at 5 keV and all constituents were detected with an O:Ti ratio of 3.47:1 for FTO-TiO2/PEG using SP-Green. Measurement of voltage-current (IV) using a digital multimeter indicated that the best occurred in the DSSC with SP-Green, resulting in a short-circuit current density (Isc) of 0.0047 mA/cm2, an open-circuit voltage (Voc) of 0.432 V, a charging factor (FF) of 0.749 and an efficiency (η) of 3.724%.
Framing Waste Classification among Chinese Young People: The Moderating Effect of Consideration of Future Consequences

ABSTRACT This study investigated the influence of two outcome framings – gain-loss framing and individual-societal framing – and an individual difference – consideration of future consequences (i.e. CFC) – on intentions to participate in waste classification and the likelihood of engaging in activities that promote waste classification. The results of an experiment (N = 215) conducted among college students in China demonstrated that individual framing was more effective than societal framing in promoting intentions to participate in waste classification, while there was no relative advantage of gain or loss framing. Furthermore, the effect of individual-societal framing was moderated by CFC. Implications of the findings were also discussed.
On doing hydrology with dragons: Realizing the value of perceptual models and knowledge accumulation

Our ability to fully and reliably observe and simulate the terrestrial hydrologic cycle is limited, and in‐depth experimental studies cover only a tiny fraction of our landscape. On medieval maps, unexplored regions were shown as images of dragons—displaying a fear of the unknown. With time, cartographers dared to leave such areas blank, thus inviting explorations of what lay beyond the edge of current knowledge. In hydrology, we are still in a phase where maps of variables more likely contain hydrologic dragons than blank areas, which would acknowledge a lack of knowledge. In which regions is our ability to extrapolate well developed, and where is it poor? Where are available data sets informative, and where are they just poor approximations of likely system properties? How do we best identify and acknowledge these gaps to better understand and reduce the uncertainty in characterizing hydrologic systems? The accumulation of knowledge has been postulated as a fundamental mark of scientific advancement. In hydrology, we lack an effective strategy for knowledge accumulation as a community, and insufficiently focus on highlighting knowledge gaps where they exist. We propose two strategies to rectify these deficiencies. Firstly, the use of open and shared perceptual models to develop, debate, and test hypotheses. Secondly, improved knowledge accumulation in hydrology through a stronger focus on knowledge extraction and integration from available peer‐reviewed articles. The latter should include metadata to tag journal articles complemented by a common hydro‐meteorological database that would enable searching, organizing and analyzing previous studies in a hydrologically meaningful manner.
A memorable tourism experience and its effect on country image

ABSTRACT This study explores the importance of memorable tourist experience for the formation of positive image traits and behaviours for a country image in a tourism context, recognizing the central role played by experiential satisfaction. Given the significance of experience design for academia and practitioners, it focuses on how memorable tourism experiences impact on image, satisfaction and behaviour. The proposed conceptual model is tested in a quantitative study that took place in Athens, Greece. The findings confirm the direct and indirect impact of memorable tourism experience on country image formation. Thus, the study offers a reliable empirical justification of a theoretically grounded model that contributes to scholarly thought and practitioners’ understanding on how to best inspire future behaviour through experience.
Floating terahertz metamaterials with extremely large refractive index sensitivities

In the diagnosis of severe contagious diseases such as Ebola, severe acute respiratory syndrome, and COVID-19, there is an urgent need for protein sensors with large refractive index sensitivities. Current terahertz metamaterials cannot be used to develop such protein sensors due to their low refractive index sensitivities. A simple method is proposed that is compatible with all geometrical structures of terahertz metamaterials to increase their refractive index sensitivities. This method uses patterned photoresist to float the split-ring resonators (SRRs) of a terahertz metamaterial at a height of 30 μm from its substrate that is deposited with complementary SRRs. The floating terahertz metamaterial has an extremely large refractive index sensitivity of 532 GHz/RIU because its near field is not distributed over the substrate and also because the complementary SRRs confine the field above the substrate. The floating terahertz metamaterial senses bovine serum albumin (BSA) and the protein binding of BSA and anti-BSA as BSA, and anti-BSA solutions with low concentrations that are smaller than 0.150 μmol/L are sequentially dropped onto it. The floating terahertz metamaterial is a great achievement to develop protein sensors with extremely large refractive index sensitivities, and has the potential to sense dangerous viruses. © 2021 Chinese Laser Press.
Forming Competency in Health Promotion in Technical Specialists Using Physical Education

In the light of new information, environmental, educational and production conditions, the problem of creating a health-promoting environment in a technical university appears to be rather important and needs to be studied in detail. The research aims to develop, justify and experimentally verify pedagogical conditions for forming competency in health promotion in technical students using physical education. The experiment involved two groups of students (Years 1-4): 241 individuals in the experimental group (EG) and 237 individuals in the control group (CG). Research methods include pedagogical observations, surveys, tests, self-evaluation, expert evaluation of students? practical skills, analysis of personal valeological and sport diaries of students; modelling in the framework of ascertaining and formative stages of the experiment; quantitative analysis of empirical data and its quality presentation; statistical verification of the proposed pedagogical conditions and the research hypothesis, the use of relevant tests (the Ruffier-Dickson index, the Cooper test) and quantitative indicators (Student? s t-test) in order to obtain some objective data on the results from the implementation of the author? s model. At the end of the experiment, most respondents (80 %) in the EG have reached a high level of competency in health promotion using physical education. In the CG, the differences in levels have not shown any significant changes since only 32.5% of respondents have a high level. Therefore, the results of the pedagogical experiment show some positive dynamics and confirm the effectiveness of the designed model and technology for forming competency in health promotion in technical students using physical education, which has made it possible to create qualitatively new conditions of the educational process and enhance students? motivation towards developing and realizing values in this field.

Machine learning in glaucoma: a bibliometric analysis comparing computer science and medical fields’ research

ABSTRACT The aim of this study was to analyze the current literature on the use of machine learning in glaucoma, comparing the characteristics and citations received by articles on computer science focus or medical focus. We performed a search using the Scopus database on 28th of January 2021 using appropriate keywords for journal articles and conference articles that discussed glaucoma in the context of machine and deep learning. We used Scopus-based field classification and compared different characteristics and citation metrics between articles classified as belonging to the computer science field, medical field, or both fields combined. A total of 858 documents resulted from the search. Upon comparing the mean citation received by publications in the computer science field and medical field, we found a significant difference (p = 0.013). The highest mean citation received was for articles in the combined fields with a mean of 26.2 (SD 41.7), and the least mean citations received by articles in computer science field with a mean of 13.7 (SD 34.6). Most articles related to machine learning assessment of glaucoma were classified as computer science articles. Articles that belong to medical or both fields combined received higher number of citations.
REFLECTIVE PRACTICE: ITS KNOWLEDGE, PRACTICE AND PERCEPTION DURING COVID-19 AMONG PAEDIATRIC NURSING STUDENTS

Purpose: This study sought to explore the knowledge level, practice and perception of the usefulness of reflective practice among pediatric nursing students in the face of the COVID-19 pandemic. Methodology: A quantitative descriptive cross-sectional study was used in carrying out the study. The study was conducted among pediatric nursing level 300 and 400 students of the University for Development Studies, Tamale, with an age range between 17 and 38. A structured questionnaire in electronic form (using Google forms) was administered to respondents through their class social media (WhatsApp) platform. Data analyses were done using the Statistical Package for Social Sciences (SPSS) version 21 and Microsoft Excel. The Fisher Exact Test was used to determine how statistically significant independent variables influence the dependent variables. Results: Findings showed that 88.5% (54/61) of the students knew reflective practice, 98.4% of them practised reflection. All respondents agreed that reflective practise has a positive impact on personal and professional development. No association existed between the age of respondents and knowledge of reflection (Fisher’s exact test=5.18; p=0.159). However, there were significant differences between the sex of respondents and knowledge of reflection (Fisher’s exact test=12.09; p=0.001) and between the class of respondents and their level of knowledge (Fisher’s exact test=10.90; p=0.004). Conclusion: Reflection is a very useful professional and personal development tool that yields positive care and learning outcomes when effectively practised. Hospitals and educational institutions should develop processes and practices that make refective practice an early and routine part of an everyday classroom and clinical practice. Recommendation: Reflection should be developed as a course and be inculcated into the first-degree nursing curriculum in universities.
Effect of Needle Size on Diagnosis of Sarcoidosis with Endobronchial Ultrasound-guided Transbronchial Needle Aspiration: Systematic Review and Meta-Analysis.

Background: Sarcoidosis is a multisystem disease characterized by noncaseating granulomatous inflammation that most commonly involves the lungs. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has become an invaluable tool in the assessment of patients with mediastinal and/or hilar lymphadenopathy. Objective: It has been hypothesized that use of the larger 19-gauge (G) needle with EBUS-TBNA improves diagnostic sensitivity in sarcoidosis. However, it is unclear whether the existing literature supports this supposition. Data Sources: A literature search of Embase and Medline was performed by two reviewers. Included articles were evaluated for bias using the QUADAS-2 tool. Data Extraction: For quantitative analysis, we performed a meta-analysis using a binary random-effects model to determine pooled sensitivity. Subgroup analysis was performed based on needle size, use of rapid on-site evaluation (ROSE), study design, and prevalence of sarcoidosis in study group. Synthesis: Sixty-five studies with a total of 4,242 patients were included in the meta-analysis. Overall pooled sensitivity for diagnosis of sarcoidosis was 83.99% (95% confidence interval [CI], 81.22-86.53) among all studies. The 19G subgroup had a significantly higher sensitivity (93.73%; 95% CI, 89.72-97.74%; I2 = 0.00%; P < 0.01) compared with the 21G subgroup (84.61%; 95% CI, 78.80-90.42%; I2 = 69.83%), 22G subgroup (84.07%; 95% CI, 80.90-87.24%; I2 = 85.21%) or unspecified 21G/22G subgroup (78.85%; 95% CI, 70.81-86.90%; I2 = 84.47%). There were no significant differences with use of ROSE or prevalence of sarcoidosis or by study design. Conclusions: The use of 19G needles during EBUS-TBNA had the highest diagnostic sensitivity based on available studies. Further randomized controlled trials using 19G needles should be considered in patients with suspected sarcoidosis.
Variations in Cosmic Noise Absorption in Association With Equatorward Development of the Pulsating Auroral Patch: A Case Study to Estimate the Energy Spectra of Auroral Precipitating Electrons

This study focused on a pulsating aurora event associated with aurora morphological changes in Fennoscandia in the early morning on March 7, 2017. A high‐speed sampling all‐sky camera captured equatorward development of the pulsating auroral patch in association with a substorm centered over the Greenland/North America region. Of particular interest in this event is the interconnection between the auroral intensity and the cosmic noise absorption (CNA) derived from three riometers aligned meridionally in Finland (from north to south: Ivalo, Sodankylä, and Rovaniemi). The analysis was made by dividing optical measurements into two oscillation components: longer and shorter than 40 s, that is, nonpulsating and pulsating auroral modulations. The interrelation between the auroral brightness and CNA showed a linear correlation. The inclination of the regression line changed with time depending on latitudes, which was interpreted as hardening or softening of the precipitating electron spectrum. Especially in the case of the low‐pass component, the inclination of the CNA‐vs‐intensity interrelation increased at the three riometer latitudes in the substorm recovery phase. On the other hand, for the high‐pass component, the inclination decreased at Rovaniemi (lower latitude) but remained uniform at Sodankylä (higher latitude). These features suggest that the precipitating electron spectrum has softened in the low‐pass or nonpulsating auroral component, but the spectrum has hardened in the high‐pass or pulsating auroral component on the lower latitude part of the auroral patch region. This study proposes a new application of riometer‐camera measurements to examine auroral particle precipitation.
Promoting Rehabilitation Among Youth on Probation: An Examination of Strengths as Specific Responsivity Factors

Despite calls for strength-focused approaches in juvenile justice, there is little research on the role of strengths in probation case management. This is one of the first studies to examine whether strengths function as specific responsivity factors as proposed by the risk–need–responsivity model, through mediating and moderating effects, and findings lend preliminary support to this conceptualization. In a sample of 261 justice-involved youth, the relationship between strengths and recidivism was found to be partially mediated by the service-to-needs match rate, even while controlling for risk—suggesting that strengths have an important indirect effect on recidivism through their impact on youth’s engagement in and completion of services. Strengths, however, did not moderate the relationship between service-to-needs match and reoffending, suggesting that appropriately matched services are essential irrespective of a youth’s strength profile. Research corroborating these findings and examining the feasibility of front-line use of strengths information is warranted.
