There has been a growing interest in Health Informatics applications, research, and education within the Middle East and North African Region over the past twenty years. People of this region share similar cultural and religious values, primarily speak the Arabic language, and have similar health care related issues, which are in dire need of being addressed. Health Informatics efforts, organizations, and initiatives within the region have been largely under-represented within, but not ignored by, the International Medical Informatics Association (IMIA). Attempts to create bonds and collaboration between the different organizations of the region have remained scattered, and often, resulted in failure despite the fact that the need for a united health informatics collaborative within the region has never been more crucial than today. During the 2017 MEDINFO, held in Hangzhou, China, a new organization, the Middle East and North African Health Informatics Association (MENAHIA) was conceived as a regional non-governmental organization to promote and facilitate health informatics uptake within the region endorsing health informatics research and educational initiatives of the 22 countries represented within the region. This paper provides an overview of the collaboration and efforts to date in forming MENAHIA and displays the variety of initiatives that are already occurring within the MENAHIA region, which MENAHIA will help, endorse, support, share, and improve within the international forum of health informatics.

Objective 1. To evaluate and optimize commonly used nonlinear deformation algorithms when applied to human brain MRI. 2. To evaluate and optimize accuracy of automated atlas-based segmentation of the two most commonly used target regions for deep brain stimulation (DBS), the nucleus subthalamicus (STN) and the internal part of the globus pallidus (GPi). 3. To guide clinicians as to which preoperative MRI sequences to acquire in patients undergoing DBS. Background Translating single-subject imaging into a common reference frame such as the MNI space is a ‘core concept within the field of brain mapping’ (Evans et al., 2012) making an accurate transformation into this space necessary. Here, we evaluated and optimized 6 commonly used deformation algorithms and compared each outcome to manually labeled brain regions of 103 brains. Methods Algorithms evaluated were: New Segment, DARTEL and SHOOT (SPM); FNIRT (FSL); SyN and BSpline (ANTs). Target space was the MNI 2009b NLIN space. An atlas of the STN and GPi in MNI space (Ewert et al., 2017) was transformed to native space by inverting each deformation matrix. The resulting atlas-based segmentations were then compared to expert manual segmentations of the native brains. Overlap between the two was quantified using the Dice coefficient (Dice et al., 1945), mean surface distance and correlation of volumes. Two open source datasets were used: The IXI-dataset ( http://***/ixi-dataset/ ) and the HCP-dataset ( http://***/ ). Results The best performing algorithms were New Segment with a custom tissue probability map (TPM) (1) and ANTs SyN (2) with an additional step to refine subcortical coregistration. Performance is compared to inter-rater results (3) of manual segmentations. Fig. 1 shows results for the HCP data for STN (L, in red) and GPi (R, in blue) separately: median Dice for STN (1): 0.70 (std: 0.1); (2): 0.72 (0.06); (3): 0.76 (0.09).

This paper presents an interactive approach to the construction of a grid-semantic map for the navigation of service robots in an indoor environment. It is based on the Robot Operating System(ROS) framework and contains four modules, namely Interactive Module, Control Module, Navigation Module and Mapping Module. Three challenging issues have been focused during its development:(i) how human voice and robot visual information could be effectively deployed in the mapping and navigation process;(ii) how semantic names could combine with coordinate data in an online Grid-Semantic map; and(iii) how a localization–evaluate–relocalization method could be used in global localization based on modified maximum particle weight of the particle swarm. A number of experiments are carried out in both simulated and real environments such as corridors and offices to verify its feasibility and performance.

Focusing on the quality of education, skills, and employability of our graduates in computing-related fields, this work proposes a cost-effective approach to achieve these goals. The Evaluation and Proficiency Infrastructure, Curricula, and Services (EPICS) extends successful methods in other units on campus in an innovative way as synergistic combination of faculty, Graduate Teaching Assistants (GTAs), and educational technology using the Canvas Webcourses Learning Management System (LMS) already in use at our college. We integrate computer-based evaluation with a close-knit review and learning cycle based on directed and open tutoring to collectively form the Evaluation and Proficiency Center (EPC). Initial results have been encouraging, as students' test scores and survey results indicate a 43% reduction in D or F grades compared to a section of the same course with the same instructor, using conventional delivery, and overwhelmingly positive responses from students regarding the effectiveness of pedagogical strategies (i.e., Exemplar Vignettes, content tutoring), assessment models (i.e., electronically delivered quizzes, flexible scheduling, use of testing center), and tutoring strategies (i.e., self-paced, exam results review). In this manuscript, the EPICS process, as well as results collected from student performance and perceptions of the initial implementation, will be addressed. © American Society for engineering Education, 2016.

Potential Fluctuations at Low Temperatures in Mesoscopic-Scale SmTiO3/SrTiO3/SmTiO3 Quantum Well Structures

Heterointerfaces of SrTiO3 with other transition metal oxides make up an intriguing family of systems with a bounty of coexisting and competing physical orders. Some examples, such as LaAlO3/SrTiO3, support a high carrier density electron gas at the interface whose electronic properties are determined by a combination of lattice distortions, spin-orbit coupling, defects, and various regimes of magnetic and charge ordering. Here, we study electronic transport in mesoscale devices made with heterostructures of SrTiO3 sandwiched between layers of SmTiO3, in which the transport properties can be tuned from a regime of Fermi-liquid like resistivity (ρ ∝ T2) to a non-Fermi liquid (ρ ∝ T5/3) by controlling the SrTiO3 thickness. In mesoscale devices at low temperatures, we find unexpected voltage fluctuations that grow in magnitude as T is decreased below 20 K, are suppressed with increasing contact electrode size, and are independent of the drive current and contact spacing distance. Magnetoresistance fluctuations are also observed, which are reminiscent of universal conductance fluctuations but not entirely consistent with their conventional properties. Candidate explanations are considered, and a mechanism is suggested based on mesoscopic temporal fluctuations of the Seebeck coefficient. An improved understanding of charge transport in these model systems, especially their quantum coherent properties, may lead to insights into the nature of transport in strongly correlated materials that deviate from Fermi liquid theory.

In recent years, expression education that improves imagination and communication skills has been of increasing interest. Suitable support and evaluation for each student in expression education is necessary because students have different skill levels. However, many existing educational institutions educate learners in a one-to-many environment. This makes it difficult for teachers to support and evaluate all learners adequately. In this study, we use a robot as an alternative to a teacher in a one-to-one environment. Suzuki et al. proposed a robot for supporting expression education that gives hints to arouse imagination. They suggested that the robot has a positive effect on learning support but cautioned that it is necessary for learners to have an interest in the robot and to pay attention to it in order for the effect to be felt. In this paper, we focus on the nod in non-verbal communication and propose a robot for supporting expression education that nods and gives hints. To determine the effectiveness of the proposed robot, we performed experiments in which we compare its performance with that of a robot that nods but does not give hints, a robot that gives hints but does not nod, and a robot that neither nods nor gives hints.

High quality Au/hBN/Au tunnel devices are fabricated using transferred atomically thin hexagonal boron nitride as the tunneling barrier. All tunnel junctions show tunneling resistance on the order of several kΩ/µm2. Ohmic I-V curves at small bias with no signs of resonances indicate the sparsity of defects. Tunneling current shot noise is measured in these devices, and the excess shot noise shows consistency with theoretical expectations. These results show that atomically thin hBN is an excellent tunnel barrier, especially for the study of shot noise properties, and this can enable the study of tunneling density of states and shot noise spectroscopy in more complex systems.

Static diagrams are the most prevalent artifact used in visualizing component-and-connector architectures and supporting software architecture learning. The use of such artifacts exhibits a fundamental disconnect from the dynamic nature of software systems, deemphasizes the importance of architectural interactions with a focus on static structure, and does not support a high degree of learner engagement. This paper presents our work in addressing these challenges by developing runtime visualization techniques that better support learning through the use of visual vocabularies that leverage insights from computer graphics and human perception. We also present evaluative data drawn from user studies and associated insights, which provide positive indicators that our work is effective in supporting our target learning outcomes.

MOOCs are increasingly being used to impart education at different levels. However, skill based courses are still in their early age. This paper presents a study done on a 3D animation MOOC. Learner data of performance in quizzes, perception of learning, and interest was gathered. Participants were grouped, accordingly to their prior exposure to online courses, as first time learners experienced learners. The effectiveness (9.1% completion rate) of the MOOC, was analyzed by comparing the perceptions of these two groups. First time learners perceived the contribution of the video towards their learning gain, more than the experienced learners. No difference in the perceived degree of contribution of specific aspects of the course like quizzes, assignments, and discussion forums was found.
