Introducing Road Surface Conditions into a Microscopic Traffic Simulation
Authors: Weber Thomas , Driesch Patrick , Schramm Dieter
Published: August 2019

The introduction of highly automated driving functions is one of the main research and development efforts in the automotive industry worldwide. In the early stages of the development process, suppliers and manufacturers often wonder whether and to what extend the potential of the systems under development can be estimated in a cheap and timely manner. In the context of a current research project, a sensor system for the detection of the road surface condition is to be developed and it is to be investigated how such a system can be used to improve higher level driving functions. This paper presents how road surface conditions are introduced in various elements of the microscopic traffic simulation such as the actual network, the network editor, a device for detection, and an adaptation of the standard Krauß car following model. It is also shown how the adaptations can subsequently affect traffic scenarios. Furthermore, a summary is given how this preliminary work integrates into the larger scope of using SUMO as a tool in the process of analyzing the effectiveness of a road surface condition sensor.
Analyzing the behavior of bicyclists using a bicycle simulator with a coupled SUMO and DYNA4 simulated environment
Authors: Kaths Heather , Keler Andreas , Kaths Jakob , Busch Fritz
Published: August 2019

Operational behavior models are used in traffic simulations to represent the subconscious, short-termdecisions made by road users to respond to other road users, the infrastructure and traffic control measures. Calibration and validation of these models can be achieved using observed trajectory data from real road users. For lane bound traffic, it is assumed that road users intend to follow a given lane with a certain desired speed across the intersection. Any deviation from this planned path is in response to other road users or the environment. It is difficult, however, to identify and separate the desired movement of more flexible road users that do not follow lane disciple, such as bicyclists, from movements made as a reaction to other road users or obstacles. This can lead to poor calibration of operational behavior models and unrealistic behavior in the simulation. Tactical behavior models recreate the conscious decisions made on a time horizon of seconds to minutes to cope with the immediate traffic situation. As such, tactical behavior models are responsible for selecting the planned path across an intersection.

Here, SUMO is coupled with the simulation software DYNA4 to create a simulated road environment for a bicycle simulator. Trajectories observed in reality are displayed as potential prescribed pathways across the simulated intersection. Participants in the simulator study are instructed to select and follow one of the prescribed pathways as closely as possible while responding naturally to other road users and obstacles in the environment. The resulting trajectory data is used to calibrate existing operation al and tactical path finding behavior models for bicyclists at signalized intersection.

Published: August 2019

The recent advances in adaptive control and autonomous vehicles have given rise to the studies on cooperative control of road vehicles, and the consequent effects on traffic flow performances. In this paper, we summarize our findings from a simulation-based solution of a problem that seeks the joint optimization of a number of link-based performances of vehicular traffic flow considering explicitly the emissions exhausted using the Eclipse SUMO micro-simulation environment in order to discuss the effectiveness of the penetration rates of cooperatively controlled vehicles in mixed traffic.
Anticipating Automated Vehicle Presence and the Effects on Interactions with Conventional Traffic and Infrastructure

Published: August 2019

Expectations are that automated and connected mobility will increase road safety and traffic efficiency. However, due to possible shortcomings of new technologies , road users may be confronted with disturbances and potential safety risks. The mitigation of such risks will bring necessary changes to road infrastructure, vehicles and road-users’ behavior. In a traffic environment that was built to fit the human perception, preemptive simulation of parametrized scenarios can provide guidelines for what changes and difficulties are to be expected. Utilizing SUMO in varied scenarios, this paper outlines the creation of virtual models that correspond to interaction hot spots on the Austrian road network - from digitizing the infrastructure, to calibrating a simulation scenario with congruent traffic measurements - while it concludes with the evaluation of scenario simulation results. The approach is demonstrated for a selected motorway ramp scenario, varying rates of automated vehicles and different infrastructure layouts. Performance indicators like vehicle speed distributions and traffic disruptions are defined and analyzed to investigate how adaptations can mitigate risks, influence traffic flow and hence support progressing vehicle automation.

Authors: Bieker-Walz Laura , Behrisch Michael
Published: August 2019

For emergency vehicle drivers it is an important task to reach the incident location as fast as possible. Therefore a self-organizing green wave could help emergency vehicles to accomplish this goal. This study presents an approach how emergency vehicle can be prioritized at traffic lights and simulates the possible benefit for the emergency vehicle. Traffic data from vehicular communication can be used to find the optimal timing for the traffic light to modify the existing traffic phases and reduce the possible negative impact on other traffic participants.

Мета роботи. Проведення на базі одного центру ретроспективного аналізу впливу гострого пошкодження нирок (ГПН) на смертність пацієнтів, яким виконували екстракорпоральну мембранну оксигенацію (ЕКМО).

Матеріали та методи. На базі ДУ «НПМЦ ДКК» у період з 2014 по 2018 рік було проведено 11 процедур ЕКМО. Екстракорпоральну мембранну оксигенацію було розпочато у 7 (64 %) пацієнтів у зв’язку з розвитком гострої серцевої недостатності; у 2 (18 %) – через пневмонію та розвиток гострого респіраторного дистрес-синдрому; в 1 (9 %) пацієнта причиною став сепсис та ще в 1 дитини (9 %) – аритмія. Під час лікування ГПН у наших пацієнтів ми застосовували дві методики: перитонеальний діаліз та модифіковану ультрафільтрацію. Для діалізу використовували розчин «Діавітек ПД» 4,25 % компанії «Юрія-Фарм», для ультрафільтрації – гемоконцентратори Medos® та Terumo®.

Результати та обговорення. Кількість успішних процедур ЕКМО становила 7 (63,5 %) з 11. Ми вважали процедуру ЕКМО успішною, якщо після деканюляції пацієнт прожив протягом 48 год. Із 7 успішно деканюльованих пацієнтів 3 (43 %) були виписані з лікарні.

З 11 пацієнтів в 1 дитини (9 %) функція нирок була збережена, а в 10 (91 %) розвинулося ГПН AKIN3. У зв’язку з ГПН для замісної терапії 6 (55 %) дітям проводили ультрафільтрацію, 1 (9 %) – перитонеальний діаліз; у 3 (27 %) дітей терапію не проводили.

Після запуску ЕКМО ми суттєво покращили кровообіг. За рахунок здійснення ефективної перфузії тканин досягли нормалізації рівня сироваткового лактату на 2-у добу після запуску ЕКМО, діурез відновився на 3-ю–4-у добу, рівень креатиніну знизився на 8–9-у добу.

Усі пацієнти, що перебували на замісній нирковій терапії, мали позитивну динаміку в лікуванні ГПН, але з летальним наслідком за рахунок інших причин. Загальна летальність становила 73 %.

Висновки. Екстракорпоральна мембранна оксигенація – це процедура, що дозволяє проводити доставку кисню в критичних пацієнтів, коли інші методи інтенсивної терапії неефективні. У 90 % пацієнтів, яким виконували ЕКМО, розвинулося ГПН, що потребувало проведення замісної терапії, в тому числі і ультрафільтрації. Гостре пошкодження нирок, що потребує замісної терапії, є предиктором погіршення перебігу захворювання та підвищення летальності в дітей із вродженими вадами серця, які перенесли оперативне втручання з використанням апарату штучного кровообігу. Проведення ультрафільтрації не супроводжувалося розвитком ускладнень та давало змогу отримати від’ємний водний баланс.

A multimodal speech-gesture training intervention for patients with schizophrenia and its neural underpinnings – the study protocol of a randomized controlled pilot trial
Authors: Riedl Lydia , Straube Benjamin
Published: August 2019

Dysfunctional social communication is one of the most stable characteristics in patients with schizophrenia that also affects quality of life. Interpreting abstract speech and integrating nonverbal modalities is particularly affected. Considering the impact of communication on social life but failure to treat communication dysfunctions with usual treatment, we will investigate the possibility to improve verbal and non-verbal communication in schizophrenia by applying a multimodalspeech-gesture training (MSG training). Here we describe the newly developed MSG training program and the study design for the first clinical investigation.The intervention contains perceptive rating (match/mismatch of sentence and gesture) and memory tasks (n-back tasks), imitation and productive tasks (e.g., SG fluency – similar to verbal fluency where words are accompanied by gesture). In addition, we offer information about gesture as meta-learning element as well as homework for reasons of transfer to everyday life as part of every session. In the MSG training intervention, we offer eight sessions (60 minutes each) of training. The first pilot study is currently conducted as a single-center, randomized controlled trial of speech-gesture intervention versus wait-list control with a follow-up. Outcomes are measured through pre-post-fMRI and standardized psychological questionnaires comparing two subject groups (30 patients with schizophrenia and 30 healthy controls). Patients and healthy controls are randomized in two intervention groups (with 20 being in the wait-training group and 10 in the training-follow-up group).With our study design we will be able to demonstrate the beneficial effect of the MSG training intervention on behavioral and neural levels.

Continuous-Time Deconvolutional Regression for Psycholinguistic Modeling
Authors: Shain Cory , Schuler William
Published: August 2019

The influence of stimuli in psycholinguistic experiments diffuses across time because the human response to language is not instantaneous. The linear models typically used to analyze psycholinguistic data are unable to account for this phenomenon due to strong temporal independence assumptions, while existing deconvolutional methods for estimating diffuse temporal structure model time discretely and therefore cannot be directly applied to natural language stimuli where events (words) have variable duration. In light of evidence that continuous-time deconvolutional regression (CDR) can address these issues (Shain & Schuler, 2018), this article motivates the use of CDR for many experimental settings, exposits some of its mathematical properties, and empirically evaluates the influence of various experimental confounds (noise, multicollinearity, and impulse response misspecification), hyperparameter settings, and response types (behavioral and fMRI). Results show that CDR (1) yields highly consistent estimates across a variety of hyperparameter configurations, (2) faithfully recovers the data-generating model on synthetic data, even under adverse training conditions, and (3) outperforms widely-used statistical approaches when applied to naturalistic reading and fMRI data. In addition, procedures for testing scientific hypotheses using CDR are defined and demonstrated, and empirically-motivated best-practices for CDR modeling are proposed. Results support the use of CDR for analyzing psycholinguistic time series, especially in a naturalistic experimental paradigm.
Disagreeing about Crocs and socks: Creating profoundly ambiguous color displays
Authors: Wallisch Pascal , Karlovich Michael
Published: August 2019

There is an increasing interest in the systematic disagreement about profoundly ambiguous stimuli in the color domain. However, this research has been hobbled by the fact that we could not create such stimuli at will. Here, we describe a design principle that allows the creation of such stimuli and apply this principle to create one such stimulus set - “the crocs and socks”. Using this set, we probed the color perception of a large sample of observers, showing that these stimuli are indeed categorically ambiguous and that we can predict the percept from fabric priors resulting from experience. We also relate the perception of these crocs to other color-ambiguous stimuli - “the dress” and “the sneaker” and conclude that differential priors likely underlie polarized disagreement in cognition more generally.
Engaging for Puerto Rico: #RickyRenuncia (and #RickySeQueda) during El Verano del 19 and digital identities
Authors: Perez-Rivera Danilo T , Lugo Christopher Torres , Santos-Lozada Alexis R
Published: August 2019

Between July 13-24, 2019 the people of Puerto Rico took the streets after a series of corruption scandals shocked the political establishment. The social uprising resulted in the ousting of the Governor of Puerto Rico (Dr. Ricardo Rosselló, Ricky), the resignation of the majority of his staff something unprecedented in the history of Puerto Rico; this period has been called El Verano del 19 (Summer of 19). Social media played a crucial role in both the organization and dissemination of the protests, marches, and other activities that occurred within this period. Puerto Ricans in the island and around the world engaged in this social movement through the digital revolution mainly under the hashtag #RickyRenuncia (Ricky Resign), with a small counter movement under the hashtag #RickySeQueda (Ricky will stay). The purpose of this study is to illustrate the magnitude and grass roots nature of the political movement’s social media presence, as well as their characteristics of the population of both movements and their structures. We found that #RickyRenuncia was used approximately one million times in the period of analysis while #RickySeQueda barely reached 6,000 tweets. Particularly, the pervasiveness of cliques in the #RickySeQueda show concentrations of authority dedicated to its propagation, whilst the #RickyRenuncia propagation was much more distributed and decentralized with little to no interaction between significant nodes of authority. Noteworthy was the role of the Puerto Rican diaspora in the United States of America and around the world, contributing close to 40% of all geo-located tweets. Finally, we found that the Twitter followers of the former governor had indicators of being composed of two distinct populations: 1) those active in social media and 2) those who follow the account but who are not active participants of the social network. We discuss the implications of these findings on the interpretation of emergence, structure and dissemination of social activism and countermovement to these activities in the context of Puerto Rico.
Censoring the Outsider: The Theatre of Albert Camus in Franco’s Spain
Authors: O’Leary Catherine
Published: August 2019

This article analyses the significance and reception of Albert Camus’s theatre in Spain under the Franco dictatorship (1939–75), which differed from that in France and elsewhere. The state censorship files at the Archivo General de la Administración in Alcalá de Henares reveal how performances of Camus’s theatre were considered rallying points of opposition to the dictatorship and yet were often tolerated. An analysis of this contradiction helps us not only to fill a gap in Spanish theatre history, which generally focuses little on foreign drama, but also to throw light both on the use of foreign drama as a form of protest and on the transnational legacy of Camus’s theatre.

Informed consent is approval of medical action which is given by the patient or his immediate family after obtaining a complete explanation about medical or dentist action that will be performed on that patient. This study aims to determine the influence of social demography and access to information on giving consent of medical action toward an understanding of informed consent in Public hospital with class C at Pekanbaru. This study employs quantitative method with cross sectional analytic design. The population in this study were all Patient or Families of patient who had received medical treatments in inpatient room for three days before the return of patient as much 267 respondent where the total sample of this research are 194 respondents. The sampling technique is Proportional Random Sampling. Data analysis was carried out in three stages: univariate, bivariate, and multivariate analysis. Based on the result of study found that there was a significant relationship between Education variable  (p value 0.007 POR 2,368), work variable (p value 0.042 POR 1,937), age (p value 0.017 POR 2,158), Completeness Information (p value 0.001 POR 2,857), Language Delivery (p value 0.002 POR 2,871) with an understanding of the approval of medical action. Based on the results of multivariate test, it was found that education, completeness of information and language of delivery were the most influential factors.The submission of information must be adjusted to the characteristics of consent provider, especially those related to education, completeness of information and language delivery, so that, if things happen that are not desirable after surgery, the patient or family is expected to receive it because before the surgery is done, the doctor has given an explanation to the patient.

Published: August 2019

An effective teaching and learning using Information and Communication Technology (ICT) is necessary to facilitateÂ  students to the easy access world of knowledge. The use of ICT essentially leads to significant impact on a condusive learning environment and also on the studentsâ€™ achievements. In Malaysia, the students come from different background and ethnics, which include orang Asli.Â  The urban students might face less difficulties in accepting the ICT in their lessons. A question then raised regarding the readiness of the Orang Asli students, particularly in remote areas, like Royal Belum, Malaysia. This paper investigates the readiness of the primary students, namely from the Jahai group,Â  in Royal Belum on the use of ICT devices, such as notepad and laptop. In addition to that, we studied the internet facilities and its connectivity at the schools, including some other related issues. Outcome of the observations showed positive readiness of Orang Asli students in using ICT devices. Nevertheless, a substantial effort from the ICT teachers seems crucial to the effective delivery of the ICT syllabus. Additionally, the schools suffer with slow connectivity as the data rate of 20 Mbps needs to be shared with other nearby schools. This has affected the studentsâ€™ learning and also the teachersâ€™ daily tasks, for instance, in meeting District Education Department (PPD) requirements regarding uploading marks online. Therefore, it is appropriate for the government agencies to search some initiatives in solving the current issues.

Published: August 2019

The Late Mesozoic igneous province of East Asia in connection with global geological events is considered. The main structure-forming events and the largest magmatic productivity of the province coincided with the peak of widely manifested plume activity in the Early Cretaceous. A geodynamic model of the magmatic province formation is proposed, relating development of the province with the complex geodynamic setting for the interaction of the convergent boundary with the hot mantle field. The Pacific marginal magmatic belt was formed in front zone of convergence where accretion of terranes occurred with prevalence of supersubduction magma-forming mechanisms. In the western part of the province outside of convergence zone an intraplate volcanic areas were formed due to activity of small mantle plumes.
Global Clinical Dementia Rating Score of 0.5 May Not Be an Accurate Criterion to Identify Individuals with Mild Cognitive Impairment
Authors: Wada-Isoe Kenji , Kikuchi Takashi , Umeda-Kameyama Yumi , Mori Takahiro , Akishita Masahiro , Nakamura Yu ,   on behalf of the ABC Dementia Scale Research Group
Published: August 2019

Many studies use the global clinical dementia rating (CDR) of 0.5 as a criterion for mild cognitive impairment, but past studies have not fully discussed its validity. The authors developed the ABC Dementia Scale (ABC-DS) to accurately monitor the changes in activities for daily living, behavioral and psychological symptoms of dementia, and cognitive function. When we carried out a cluster analysis of ABC-DS scores of 110 individuals for whom global CDR was 0.5, there were three groups with different levels of activities for daily living and cognitive function. O’Bryant et al. proposed a new guideline to stage dementia using the CDR sum of boxes scores (CDR-SOB). We used their proposal and ABC-DS scores to evaluate the validity of CDR 0.5 as a definition of mild cognitive impairment (MCI). We concluded that the CDR-SOB scores and ABC-DS score are more accurate than global CDR of 0.5 for specifying individuals with MCI.

In this paper, we shall try to shed some light on the very pressing and challenging issue of ethics in technologies under the umbrella of AI. This concern has to be discussed extensively by philosophers, economists, and AI research scholars and this process of discussion is a continuous one. Autonomous services especially those involving the use of systems that have both aspects socio-technical [5] ones can increasingly become a major factor in making the environment hostile. The inclusion of human morals into human-level intelligence systems [8] is crucial. The capacity of the human mind for formulating, ideating, conceptualizing, thinking, innovating and solving complex problems is minuscule compared with the mass of the problems, those of whom have solutions, which are essential for objectively rational and moral behavior in the real world or even for a novice reasonable approximation to such target sanity. Equally important notions to be considered to avoid possible shortcomings in and havocs due to this technology are involvement of human ethics, consideration of social and moral implications of the same.

This article presents the theoretical and methodological aspects of the activist science and technology education practices of a Brazilian outreach initiative known as Science Stand. This learn-by-doing program is designed to connect science and technology to current global socio-ecological issues – such as animal rights, gender (in)equality, and climate change – through interactive activities created and performed by university students in public spaces located in marginalized communities in the Greater São Paulo Area (Brazil). In addition, we introduce several testimonies from project volunteers that support our argument concerning the role of science activism in advocating gender equity in science, fostering hope in the possibility of socio-ecological change, and promoting the democratization of science through widespread knowledge dissemination.
(Re)engaging Our Ethical Commitments and Becoming Activists in Our Own Backyards
Authors: Rodriguez Alberto J.
Published: August 2019

In this manuscript, I provide an example of what activism in your own backyard may look like in institutional contexts using Foucault’s notions of ethics. To this end, I report findings from a two-year study conducted in my own science methods courses with two cohorts of pre-service teachers. Through a critical autoethnographic lens, I recount a synthesis of struggles and successes that illustrate what happens when one’s ethical and professional commitments to work for social justice intersect (collide) with the urgent need to address opp(regre)ssive practices in our own programs. Suggestions for how to be an activist in our own backyards and how to (re)engage our ethical commitments through a praxis of self-care are also provided.
A weighty battle: managing BMI post-kidney transplantation
Authors: van der Jeugd Jane , Kathy Kathy , Gulyani Aarti
Published: August 2019

At Flinders Medical Centre (FMC), a retrospective/prospective study was performed comparing body mass index (BMI) data collection in patients attending the nurse-led clinic, as an alternative to data collection in transplant recipients using the Australia and New Zealand Data (ANZDATA) method of data collection. The aim is to understand prevalence of high BMI post-kidney transplantation, and to determine if a nurse practitioner (NP)-led wellness clinic can have a positive impact in relation to weight management in this patient cohort.
Searching for missing donors: a 12-month audit of deaths in two large Sydney teaching hospitals
Authors: Serrano Myra , Sposari Venessa
Published: August 2019

The DonateLife Audit (DLA) is undertaken at Liverpool and Royal Prince Alfred (RPA) hospitals to measure and report on actual and potential organ donation activity. This includes all patient deaths in the intensive care unit (ICU) and emergency department (ED); and, patients with a neurological condition who died within 24 hours of discharge from ICU or ED. A death review committee was established in RPA in mid-2014 and Liverpool in mid-2017 to analyse all in-hospital deaths to determine whether these hospitals were missing potential organ donors beyond the DLA parameters.
The two death review committees analysed 12 months of data for comparison. The findings showed that both hospitals have a low rate of potential organ donors who died from non-neurological conditions. It also highlighted a significant number of unsupportable patients who presented in extremis in Liverpool and a significant number of patients with no suitable organs in RPA. It can be inferred that these limit the potential donor pool and therefore further exploration of these phenomena is warranted.
Parametric Design process in Architecture

Published: August 2019

Parametric Design got a good deal of interest and debate since the 90s of the 20th century ,yet this debate increased  in size and influence when important buildings in the world by known architects were designed parametrically .These buildings have terms with compositional complexity and smoothness .They characterized the architecture uniqueness and practice  since 2000, which caused the academic and theoretical institutions and individuals in architecture to carry on research focusing on parametric design and exploring its activities .Previous studies concentrated on the exploring activity and process of parametric design, accordingly the research problem is identified as follows: The lack of knowledge of parametric design in architecture from the theoretical and detailed sides related to the role of the (architect) , act and process of design , and result of the architectural design .The objectives of the research are : Clarifying the specific knowledge on parametric design in general and in architecture in particular .Clarifying the (thought) aspects of parametric design considering it as a tool or a  way of design on an architectural approach .Clarifying the role of (parametric design) and exploring the comparative sides between it and the normal  ( traditional ) way of design.
