Road Safety in Tunnels

Roads in tunnels differ from comparable open-road sections in many respects. For most drivers a tunnel is an unusual driving environment in the road network that might even cause stress. A safety analysis was carried out to estimate average accident rates and accident cost rates for different cross sections of tunnels on German roads. The analysis is based on all the available accident data for German freeway and highway tunnels reported to police. Personal injury accidents and material-damage-only accidents were analyzed separately. The findings indicate that accident rates are lower for roads in tunnels. Moreover, accidents with severe personal injury and material damage are less frequent on roads in tunnels. However, the fear of a maximum credible accident still remains.
Maximising stakeholder learning by looping again through the simulation life-cycle: A case study in public transport

Abstract Building a simulation model of a complex system requires significant investment of expertise, time, and expense. In order for an organisation to realise the greatest return on this investment, it is advantageous to re-use a model or extend the simulation model’s life-cycle to maximise learning generated from it. Existing studies typically end after a ‘single loop’ of the simulation life-cycle, with the computer model produced at the end of it suitable for addressing the initial requirements of stakeholders. Here we explore how to further extend the modelling life-cycle by adding a ‘second loop’ in which an existing simulation model is introduced to a new group of stakeholders and then enhanced to capture additional features of the system that are of interest to this new group, but were not identified as requirements by the first group. Developed from real-world experience working with the large train operator Eurostar International Limited, we present details of our proposed methodological framework and highlight the tangible benefits of adding a second loop to the simulation life-cycle. We discuss the roles of modellers and stakeholders in the two loops of the life-cycle and compare and contrast the relationship between the two parties in each.
Do gestures really facilitate speech production?

Why do people gesture when they speak? According to one influential proposal, the Lexical Retrieval Hypothesis (LRH), gestures serve a cognitive function in speakers' minds by helping them find the right spatial words. Do gestures also help speakers find the right words when they talk about abstract concepts that are spatialized metaphorically? If so, then preventing people from gesturing should increase the rate of disfluencies during speech about both literal and metaphorical space. Here, we sought to conceptually replicate the finding that preventing speakers from gesturing increases disfluencies in speech with literal spatial content (e.g., the rocket went up), which has been interpreted as evidence for the LRH, and to extend this pattern to speech with metaphorical spatial content (e.g., my grades went up). Across three measures of speech disfluency (disfluency rate, speech rate, and rate of nonjuncture filled pauses), we found no difference in disfluency between speakers who were allowed to gesture freely and speakers who were not allowed to gesture, for any category of speech (literal spatial content, metaphorical spatial content, and no spatial content). This large dataset (7,969 phrases containing 2,075 disfluencies) provided no support for the idea that gestures help speakers find the right words, even for speech with literal spatial content. Upon reexamining studies cited as evidence for the LRH and related proposals over the past 5 decades, we conclude that there is, in fact, no reliable evidence that preventing gestures impairs speaking. Together, these findings challenge long-held beliefs about why people gesture when they speak. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
Hidradenitis suppurativa; classification, remedies, etiology, and comorbidities; a narrative review

Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition that is more common in females, especially during puberty and menopause. These inflammatory lesions include painful deep-seated nodules and abscesses, draining sinus tracts, and fibrotic scars. This article is a narrative review to explain whole disease aspects, including complication, causes, epidemiology, history, classification, prognosis, comorbidities, the effect of sex hormone, and potent treatments. Most patients with HS, who are not aware of their primary disease, visit primary care physicians to superinfection lesions instead of specialists. If these physicians suspect HS, their illness will not get misdiagnosed. This brief and comprehensive information in this article may help doctors to decide better about the same situation.
A Fully Optimized Electrowinning Cell for Achieving a Uniform Current Distribution at Electrodes Utilizing Sampling-Based Sensitivity Approach

In this paper, a zinc electrowinning cell is fully optimized to achieve a uniform current distribution at electrode surfaces. To effectively deal with an electromagnetically coupled problem with multi-dimensional design variables, a sampling-based sensitivity approach is combined with a highly tuned multiphysics simulation model. The model involves the interrelation between electro- chemical reactions and electromagnetic phenomena so as to predict accurate current distributions in the electrowinning cell. In the sampling-based sensitivity approach, Kriging-based surrogate models are generated in a local window, and accordingly their sensitivity values are extracted. Such unique design strategy facilitates optimizing very complicated multiphysics and multi-dimensional design problems. Finally, ten design variables deciding the electrolytic cell structure are optimized, and then the uniformity of current distribution in the optimized cell is examined through the comparison with existing cell designs.

Atomic-Scale Insights on Large-Misfit Heterointerfaces in LSMO/MgO/c-Al2O3

Understanding the interfaces in heterostructures at an atomic scale is crucial in enabling the possibility to manipulate underlying functional properties in correlated materials. This work presents a detailed study on the atomic structures of heterogeneous interfaces in La0.7Sr0. 3MnO3 (LSMO) film grown epitaxially on c-Al2O3 (0001) with a buffer layer of MgO. Using aberration-corrected scanning transmission electron microscopy, we detected nucleation of periodic misfit dislocations at the interfaces of the large misfit systems of LSMO/MgO and MgO/c-Al2O3 following the domain matching epitaxy paradigm. It was experimentally observed that the dislocations terminate with 4/5 lattice planes at the LSMO/MgO interface and with 12/13 lattice planes at the MgO/c-Al2O3 interface. This is consistent with theoretical predictions. Using the atomic-resolution image data analysis approach to generate atomic bond length maps, we investigated the atomic displacement in the LSMO/MgO and MgO/c-Al2O3 systems. Minimal presence of residual strain was shown at the respective interface due to strain relaxation following misfit dislocation formation. Further, based on electron energy-loss spectroscopy analysis, we confirmed an interfacial interdiffusion within two monolayers at both LSMO/MgO and MgO/c-Al2O3 interfaces. In essence, misfit dislocation configurations of the LSMO/MgO/c-Al2O3 system have been thoroughly investigated to understand atomic-scale insights on atomic structure and interfacial chemistry in these large misfit systems.
Development of an extended enterprise performance measurement system

This paper discusses the development of a performance measurement system specifically designed for the requirements of the extended enterprise, via two performance measurement frameworks: the structural extended enterprise balanced scorecard and the procedural framework for the selection and implementation of measures. The extended enterprise balanced scorecard offers a four-perspective framework, implemented at each node, that provides a generic structure for the management of performance measures in the extended enterprise; while the procedural framework operates at both the local and holistic levels, to provide a step-by-step generic process towards performance measure selection and implementation. When combined, the two frameworks produce the basic extended enterprise performance measurement (EEPM) system, which was subsequently tested at a first-tier supplier in the European automotive industry. The characteristics of the extended enterprise are taken as a given starting point, and the paper concludes by pointing out the need for extended enterprise performance management to balance the developments outlined here.
Beamforming With Dominant Mode Rejection

High resolution adaptive beamforming of a spatial array of sensors has traditionally been formulated in terms of a minimum noise variance, distor tionless response (MVDR) optimality criterion . This approach results in a constrained spatial Wiener filter structure which requires the estimation and inversion of either the array space-time correlation matrix for time domain implementation or the array cross­ spectral density matrix (CSDM) for a frequency domain implementation 1. In the situation where the array acoustic environment consists of a limited number of dominant modes the full matrix inversion procedure is both numerically and statistically inadvisable. In this case, the technique of point source interference null steering can be generalized to the nulling of dominant modes without prior knowledge of the mode structure . In effect, a reduced rank version of the spatial Wiener filter is produced which is realized as a generalized mode nulling beamformer .
The Novel Application of Three-Dimensional Printing Assisted Patient-Specific Instrument Osteotomy Guide in the Precise Osteotomy of Adult Talipes Equinovarus

Objective This current research is aimed at assessing clinical efficacy and prognosis of three-dimensional (3D) printing assisted patient-specific instrument (PSI) osteotomy guide in precise osteotomy of adult talipes equinovarus (ATE). Methods We included a total of 27 patients of ATE malformation (including 12 males and 15 females) from June 2014 to June 2018 in the current research. The patients were divided into the routine group (n = 12) and 3D printing group (n = 15) based on different operative methods. The parameters, including the operative time, intraoperative blood loss, complications, time to obtain bony fusion, functional outcomes based on American Orthopedic Foot and Ankle Society (AOFAS), and International Congenital Clubfoot Study group (ICFSG) scoring systems between the two groups were observed and recorded regularly. Results The 3D printing group exhibits superiorities in shorter operative time, less intraoperative blood loss, higher rate of excellent, and good outcomes presented by ICFSG score at last follow-up (P < 0.001, P < 0.001, P = 0.019) than the routine group. However, there was no significant difference exhibited in the AOFAS score at the last follow-up and total rate of complications between the two groups (P = 0.136, P = 0.291). Conclusion Operation assisted by 3D printing PSI osteotomy guide for correcting the ATE malformation is novel and feasible, which might be an effective method to polish up the precise osteotomy of ATE malformation and enhance the clinical efficacy.
Effects of Fan-Aspirated Radiation Shield for Temperature Measurement in Greenhouse Environment

Purpose: Provision of accurate temperature measurement is an essential element to ensure a precise control in greenhouse environment. This study was organized to compare the effects of six solar radiation shields with different shapes for temperature measurement and find the most appropriate shield for greenhouse environment. Methods: A fan-aspirated radiation shield was designed and manufactured. Using the fan-aspirated radiation shield and five other shapes i.e., the cup shape, horizontal pipe, vertical pipe, parallel boards and commercial shields, temperature measurement was conducted over the lawn surface as well as greenhouse indoor environment. The measurement height varied at 0.5, 1.0 and 1.5 m from the floor. Results: The measured temperatures by the fan-aspirated radiation shield were 1.30-1.49℃ lower than the values recorded by other different-shaped shields at 1.5 m of measurement height. As the measurement height decreases, observed differences between measured temperatures of the fan-aspirated radiation shield and other shields demonstrate a declining trend. However, at low measurement heights, the radiation emitted from the bottom surface would be the source of error in temperature measurement. Conclusions: The fan-aspirated radiation shield is a required tool for exact measurement of air temperature in greenhouse temperature control.
CHU9D Normative Data in Peruvian Adolescents

Background: Due to the vulnerability to protective and risk factors during adolescence, there is a growing interest in the study of health-related quality of life (HRQoL) at this stage. The CHU9D is a generic and practical HRQoL instrument that provides values on all dimensions of self-perceived health, in addition to providing utilities and a cost-utility assessment fee, unlike other instruments. This study was conducted with an adolescent population in Peru. The main objective of this article is to report the normative values of the CHU9D questionnaire in Peruvian adolescents. Methods: The CHU9D questionnaire was administered to Peruvian adolescent students. A total of 1229 young people participated in the survey. The CHU9D score was reflected as a function of gender, age, weight, height, and educational level. Results: The mean CHU9D utility index for the total sample was 0.890; this rating was significantly better for boys with 0.887 and girls with 0.867. The ceiling effect was higher for male adolescents with 32.6 than for female adolescents. Conclusions: The results of the present study show that adolescents in school show a positive perception of HRQoL. It is also concluded that the CHU9D instrument can be effectively applied to economic evaluations for interventions to improve the quality of life of adolescents.
Contributions of a Professional Development Course to Language Teacher Identity Development: Critical Incidents in Focus

Despite the widely recognized significance of critical incidents (CIs) in teachers’ professional learning, little research has investigated the role of CIs in language teacher identity development. This study attempts to fill this gap by exploring the contributions of a Telegram-based professional development course—framed around CI storying—to the language teacher identity development process of a group of teachers. Data were collected from 10 teachers before, during, and after the course. Data analyses indicated that, before the course, CIs negatively influenced the teachers’ agency and emotions. Participation in the course contributed, however, to the teachers’ enhanced agency and greater emotion regulation. In addition, the course afforded the teachers an opportunity to experience further professional socialization and collegial engagement. Our findings revealed that during the course, the teachers developed greater expertise in storying their CIs and discussed higher order issues relevant to the multiplicity of identity as connected to sociocultural-educational dimensions. These findings suggest that emotions and agency are two significant identity aspects that are profoundly influenced by and influence CIs. Our article closes with a discussion of the implications of embedding CIs in professional development courses to help teachers (re)construct their identities.
Effects of heat dissipation on unipolar resistance switching in Pt∕NiO∕Pt capacitors

We fabricated Pt∕NiO∕Pt capacitor structures with various bottom electrode thicknesses tBE and investigated their resistance switching behaviors. The capacitors with tBE⩾50nm exhibited typical unipolar resistance memory switching, while those with tBE⩽30nm showed threshold switching. This interesting phenomenon can be explained in terms of the temperature-dependent stability of conducting filaments. In particular, the thinner tBE makes dissipation of Joule heat less efficient, so the filaments will be at a higher temperature and become less stable. This study demonstrates the importance of heat dissipation in resistance random access memory.
Genetic algorithm to solve a multi-objective scheduling problem

Energy is expensive and a potential way to reduce energy consumption may be through using intelligent scheduling techniques. In this paper, we propose a genetic algorithm to solve a single machine scheduling problem where the objectives are minimizing total completion time and energy consumption of manufacturing equipment when all of the processing time and release dates of the job are known. This problem has several applications including scheduling in manufacturing industry, energy minimization in computers, cell phones, sensors, etc. Different fitness functions and parameters depending on the problem's characteristics were tested using a design of experiment approach. The proposed methodology generates several pareto optimal solutions. A decision maker can select one of these solutions using Analytical Hierarchical Process.
Age-Associated Developmental Trajectories For Verbal Divergent Thinking

Creativity is a complicated process that conceals a huge amount of unclear mechanisms which are the prospect to be revealed. At current well-known that the creation process requires the development of a wide range of cognitive functions. There is no consensus about age-related patterns of development of verbal creativity. In the scientific literature, there are contradictory data available supporting its linear or non-linear erratic growth, as well as lack of distinction in the level of verbal creativity at any age. At current, the speed of evolvement of cognitive attitudes and the mechanism of interaction between the accumulated knowledge, the semantic structure, and the method of solving the problem are still unclear. The research question is how the rate of age-related development of critical related to the formation of the semantic space for the flexible search for an original solution to the problem. The aim of this study was to find out the age-related features of the relationship between verbal creativity and fluid intelligence. The revealed age-related differences in the indicators of creativity and IQ and features of their relationship allow us to conclude that the speed of mental processes, executive control of choosing the best solution is not yet sufficiently developed in students aged 11-13.
Artificial intelligence learning approach through total physical response embodiment teaching on French vocabulary learning retention

Abstract TPR (Total Physical Response) is a methodology for teaching foreign languages. In traditional TPR, teachers need to spend a considerable amount of time confirming the accuracy of students’ movements, which results in a low-efficiency teaching process and affects the fairness of student learning. A motion sensing system can assess the accuracy of body movements and guide students’ movements immediately after detecting them. Hence, in this study, an artificial intelligence (AI) motion sensing teaching system that combines gesture detection and French learning was written in Python. The system was then used to understand the effectiveness of different teaching methods among kinesthetic or non-kinesthetic students in French learning. Further, a delay test was conducted to assess learning retention. There were significant differences in the effects of the interaction between instructional methodologies and learning style tendency on learning retention. By connecting gestures, words, and sounds, students in the group that used the French TPRAI motion sensing teaching system were able to recall what they had learned through body movements on the delay test 14 days after the post-test to retain learning.

Density-gradient analysis of tunneling in MOS structures with ultra-thin oxides

Quantum transport theory in the density-gradient approximation is applied to the analysis of tunneling phenomena in ultra-thin oxide (<25 A) MOS structures. Detailed comparisons are made with experimental I-V data for samples with both n/sup +/ and p/sup +/ polysilicon gates and all of the features of this data are found to be understandable within the density-gradient framework. Besides providing new understanding of the experiments, these results show the density-gradient approach to be useful for engineering-oriented device analysis in quantum regimes with current flow.
