Teleconsultation and Teletreatment Protocol to Diagnose and Manage Patients with Benign Paroxysmal Positional Vertigo (BPPV) during the COVID-19 Pandemic.

Introduction Telehealth consists in the application of technology to provide remote health service. This resource is considered safe and effective and has attracted an exponential interest in the context of the COVID pandemic. Expanded to dizzy patients, it would be able to provide diagnosis and treatment, minimizing the risk of disease transmission. Benign paroxysmal positional vertigo (BPPV) is the most common vestibular disorder. The diagnosis typically rests on the description of the symptoms along with the nystagmus observed at a well-established positional testing. Objectives The aim of the present study was to propose a teleconsultation and teletreatment protocol to manage patients with BPPV during the COVID-19 pandemic. Methods Specialists in the vestibular field met through remote access technologies to discuss the best strategy to manage BPPV patients by teleconsultation and teletreatment system. Additionally, several scientific sources were consulted. Technical issues, patient safety, and clinical assessment were independently analyzed. All relevant information was considered in order to design a clinical protocol to manage BPPV patients in the pandemic context. Results Teleconsultation for BPPV patients requires a double way (video and audio) digital system. An adapted informed consent to follow good clinical practice statements must be considered. The time, trigger and target eye bedside examination (TiTRaTe) protocol has proven to be a valuable first approach. The bow and lean test is the most rational screening maneuver for patients with suspected positional vertigo, followed by most specific maneuvers to diagnostic the sub-variants of BPPV. Conclusion Although with limited evidence, teleconsultation and teletreatment are both reasonable and feasible strategies for the management of patients with BPPV in adverse situations for face-to-face consultation.

Utilization of remote access electron microscopes to enhance technology education and foster STEM interest in preteen students.

Remote access technology in STEM education fills dual roles as an educational tool to deliver science education (Educational Technology) and as a means to teach about technology itself (Technology Education). A five-lesson sequence was introduced to eleven to twelve-year-old students at an urban school. The lesson sequences were inquiry-based, hands-on, and utilized active learning pedagogies which have been implemented in STEM classrooms worldwide. Each lesson employed a Scanning Electron Microscope (SEM) and Energy Dispersive Spectroscopy (EDS) accessed remotely. Students were assessed using multiple choice questions to ascertain (1) technology education learning gains: did students gain an understanding of how electron microscopes work? and (2) educational technology learning gains: did students gain a better understanding of lesson content through use of the electron microscope? Likert-item surveys were developed, distributed and analyzed to established how remote access technology affected student attitudes toward science, college, and technology. Participating students had a positive increase in attitudes toward scientific technology by engaging in the lesson sequences; reported positive attitudes toward remote access experiences; and exhibited learning gains in the science behind the SEM technology they accessed remotely. These findings suggest that remote experiences are a strong form of technology education, but also that future research could explore ways to strengthen remote access as an educational technology (a tool to deliver lesson content), such as one-on-one engagement. This study promotes future research into inquiry-based, hands-on, integrated lessons approach that utilize educational technology learning through remote instruments as a pedagogy to increase students' engagement with and learning of the T in STEM.

Features of High-Quality Mathematical Training in the Context of Online Education of Students Oriented to Work in the Nuclear Industry

Due to the COVID-19 coronavirus infection pandemic, the world is faced with the need for social isolation and a forced rapid transition to a “home office” and online learning. The Russian education system has almost completely switched to distance learning. Working in the new conditions turned the daily routine of both teachers and students who not only faced difficulties of various nature but also discovered new opportunities for professional growth. Traditionally, it is customary to discuss the disadvantages of distance education, but this paper considers the advantages and new opportunities of this form of education. This is especially important in the process of mathematical training of university students focused on work in the nuclear industry due to the specifics and importance of studying this subject and due to the fact that at present online training is widely implemented in the training of employees of nuclear power plants where digitalization and everything which is associated with remote access technologies, thanks to the pandemic, are in demand and irreplaceable.

FULL-KV: Flexible and Ultra-Low-Latency In-Memory Key-Value Store System Design on CPU-FPGA

In-memory key-value store (IMKVS) has gained great popularity in data centers. However, big data brings great challenges in performance and power consumption because of the general-purpose Von Neumann computer architecture. Remote direct memory access (RDMA) technology supporting zero-copy networking could partly alleviate the problem but is still not efficient for KVS. To overcome this problem, we present a flexible and ultra-low-latency IMKVS system named FULL-KV, based on a CPU-FPGA heterogeneous architecture. The FPGA serves as a KVS accelerator that can bypass the CPU and implement both the network stacks and the KVS processing with a highly parallel hardware architecture. The system latency of FULL-KV can achieve as low as 1.5μs/2.2μs for the PUT/GET operation, which is 3.0x/1.5x faster than current state-of-the-art hardware-based KVS systems. Besides, FULL-KV can support 4x larger values (up to 4M bytes). Given a total Ethernet bandwidth of 20Gbps, the peak throughput of the single-node FULL-KV can reach 26.0 million key-value operations per second (Mops). In the two-node test system with a commercial Ethernet switch, the peak throughput can reach 52Mops, manifesting the system scalability and practicability.

P-PFC: Reducing Tail Latency with Predictive PFC in Lossless Data Center Networks

Remote Direct Memory Access(RDMA) technology rapidly changes the landscape of nowadays datacenter applications. Congestion control for RDMA networking is a critical challenge. As an end-to-end layer 3 congestion control mechanism, Datacenter QCN (DCQCN) alleviates the unfairness and head-of-the-line blocking problems of Priority-based Flow Control (PFC). However, a lossless network does not guarantee low latency even with DCQCN enabled. When network congestion happens, switch queues still build-up due to the response latency of end-to-end solutions. In this article, we propose Predictive PFC (P-PFC) to reduce tail latency in RDMA networks. P-PFC monitors the derivative of buffer occupation, predicts the happening of PFC trigger in the future, and proactively triggers PFC pause in advance. The benefit is that buffer usage can be maintained at a low level, hence the tail latency can be controlled. Preliminary evaluation results demonstrate that P-PFC can reduce tail latency by more than half of that in standard PFC in many scenarios, without hurting the throughput and average latency. P-PFC can also protect innocent flows compared with standard PFC according to our experiments. To our best knowledge, this is the first work of using derivative to improve PFC in lossless RDMA networks.

Use of new technologies in water resources prospecting—A case study on Karst of the Polanco Formation, Uruguay

Hydrogeological background motivated the development of prospective groundwater models in carbonate rocks of the Polanco Formation (Ediacaran). Field and photographic surveys were carried out (SGM, Google Earth and Drone Phantom 2 Vision+), and 3D terrain models were generated to interpret the morpho-structural characteristics of the karst relief. Boreholes and geoelectric data were surveyed. Standard prospective techniques were complemented with remote ground access technologies to generate a specific prospective model for these lithologies. As a result, it was found the existence of folds that generate an inverted relief with “cup” and “tube” type dolines, a karst relief type lapiaz, three springs and the development of wells with an average flow of 30 m3/h. The hydrogeochemical composition corresponds to bicarbonate-calcium waters of natural mineral water quality.

Remote Access Therapy for Veterans With Psychological Problems: Current State of the Art.

The past decade has seen both an increase in use and research into ways in which psychological therapy might be delivered remotely. Remote access therapy uses technology to deliver talking therapies. It is important to understand how remote technologies are being used as part of the therapeutic process and consider what effect this has on the success of therapeutic interventions. This review discusses what is currently known about the use of remote access therapy with a veteran population. Moreover, the review summarizes potential benefits and barriers to conducting therapy remotely. This review was conducted to explore the use of remote access therapies with veterans. All available literature identified for this review focused on veteran cohorts from the US and UK. To meet search criteria, studies had to include veteran participants engaging with any form of talking therapy delivered remotely. A total of 15 studies met the inclusion criteria: two from the UK and 13 from the US. Searches were carried out during June and July 2019. A number of potential benefits to remote therapy delivery were observed in the research reviewed, including improved accessibility to therapy for people living in remote locations (providing infrastructure existed to facilitate the remote access technologies), increased flexibility of timing, and being able to undergo therapy alongside other life commitments. The studies also suggested that those involved in remote therapy found the technology accessible and easy to operate. Digital technologies could generally be relied upon and although there were some technical difficulties reported that these were generally not seen as a barrier to the use of remote technologies as a whole. Some limitations to using remote therapies were observed, such as the acceptability of remote therapy, particularly in the UK, and the willingness of practitioners to engage with digital technologies to facilitate remote therapy. There was also caution raised that the apparent cost effectiveness of delivering therapy remotely needs to be further investigated, particularly in relation to costs involved in enabling remote access technologies in locations where poor infrastructure exists. Overall, studies reported largely positive outcomes for veterans undergoing remote access therapy and in general participants did not find the therapeutic process compromised by remote delivery. Studies showed that remote access therapy is being conducted successfully in both the US and UK. There is, however, a need for more research into the use of remote access therapies to treat a wider range of psychological difficulties in veterans.

Cyber security and the remote workforce

Current world events have forced a sudden remote-working economy that many businesses were simply not prepared for. According to a Gartner survey of 229 human resources (HR) managers, 81% or more are working remotely, and 41% are likely to do so at least some of the time even once a return to normal working is permitted. This sudden rise in remote working is not only challenging employees to work in a way they had not previously, but it has also impacted the cyber-risk profile of enterprises worldwide. Organisations have built policies and procedures that protect individuals and the organisation's infrastructure. However, unless a significant percentage of employees had previous access to proper remote access technologies, there is a real risk of employees making bad choices. Organisations need to implement the correct tools to mitigate these threats, explains Kevin Curran of Ulster University.

Arduino Based Embedded System and Remote Access Technologies of Environmental Variables Monitoring

An embedded system is an applied computer system that is built to control a range of functions. A brief discussion of embedded systems is presented. Remote access technology is the ability to control aspects of a manufacturing process from any location. Sensors are devices which can measure a physical quantity and convert it into a signal. It is described an Arduino-based embedded system for monitoring environmental variables. One solution is the control of the different environmental variables through a website. The website displays monitoring data to the user on a 24-hour line chart. Another solution is the remote access to be based on the GSM (Global System for Mobile Communication) network. Theory explains the use of Arduino microcontroller, the use of sensors and how they are used in embedded systems.

Fast In-Memory Key–Value Cache System with RDMA

The quick advances of Cloud and the advent of Fog computing impose more and more critical demand for computing and data transfer of low latency onto the underlying distributed computing infrastructure. Remote direct memory access (RDMA) technology has been widely applied for its low latency of remote data access. However, RDMA gives rise to a host of challenges in accelerating in-memory key–value stores, such as direct remote memory writes, making the remote system more vulnerable. This study presents an in-memory key–value system based on RDMA, named Craftscached, which enables: (1) buffering remote memory writes into a communication cache memory to eliminate direct remote memory writes to the data memory area; (2) dividing the communication cache memory into RDMA-writable and RDMA-readable memory zones to reduce the possibility of data corruption due to stray memory writes and caching data into an RDMA-readable memory zone to improve the remote memory read performance; and (3) adopting remote out-of-place direct memory write to achieve high performance of remote read and write. Experimental results in comparison with Memcached indicate that Craftscached provides a far better performance: (1) in the case of read-intensive workloads, the data access of Craftscached is about 7–43[Formula: see text] and 18–72.4% better than those of TCP/IP-based and RDMA-based Memcached, respectively; (2) the memory utilization of small objects is more efficient with only about 3.8% memory compaction overhead.

Improving the Performance of Distributed MXNet with RDMA

As one of the most influential deep learning frameworks, MXNet has achieved excellent performance and many breakthroughs in academic and industrial fields for various machine learning situations. The initial implementation of MXNet uses proxy-socket interface, which delivers suboptimal performance in distributed environment. In a massive parallel training task, parameters are updated frequently during each training loop, in which case network performance becomes the main factor of overall performance. Over the past decade, high performance interconnects have employed remote direct memory access (RDMA) technology to provide excellent performance for numerous scientific domains. In this paper, we describe an efficient design that extends the open-source MXNet to make it RDMA capable via RDMA-based parameter server interfaces. With modest optimizations towards memory usage and transmission overhead, RDMA-based MXNet achieves great performance improvement over the original software. Our experiments reveal that, for the communication subsystem of MXNet, the new design achieves 16x speedup (up to 21x at peak) over 1 Gigabit Ethernet (1GigE). For the two training cases on MXNet, the optimized implementation gains 5x and 9x speedup, respectively. Compared to experiments on the IP-over-InfiniBand (IPoIB) protocol, it achieves nearly 30% performance improvement, as well as better scalability and alleviation of bottlenecks.

Dementias Platform UK (DPUK) Data Portal - World-leading infrastructure facilitating innovative multi-modal research

IntroductionModern team science requires effective sharing of data and skills. The DPUK Data Portal is a collection of tools, datasets and networks that allows for epidemiologists and specialist researchers alike to access, analyse and investigate cohort and different modalities of routine data across UK and international sources.
 Objectives and ApproachThe Portal is housed on an instance of UKSeRP (UK Secure eResearch Platform), that allows customisable infrastructure to be used for multi-modal research (thus far live in genetics, imaging and clinical data) for researchers across the world using remote access technology whilst allowing governance to remain with the data provider. A central team at Swansea University is responsible for data curation and processing, and runs an access procedure for researchers to apply to use data from multiple sources to be analysed in a central analysis environment. Other modalities are similarly hosted, with input from partner sites in Cardiff and Oxford.
 ResultsDPUK facilitates data access and research on 49 cohorts, 40 UK-based and 9 international. The centralised repository model including remote access and ability to store and make available different modalities of data, from phenotypic data, to genetic and imaging data, has allowed DPUK to begin to support research of varying topics, from those studying cognitive decline and Dementia as a disease, to those maturing analytical models. By providing access to data platforms specialising in genetics, imaging and routine clinical data, as well as to specialists in disease and biology to aid with its understanding, DPUK has realised a large-scale research exercise combining major data modalities on a central platform, and allow access to such rich data across the world under an umbrella of robust governance.
 Conclusion/ImplicationsGlobally, cohorts are pooling data, expertise and desire to enrich their own aims in partnership with a federated research community to enable in-depth scrutiny of the biological origins of dementia and the development and evaluation of novel approach to disease prevention and cure.

Barriers to online patient portal adoption among adult oncology patients.

44 Background: Recent research shows tele-health and remote access technology enhances patient-provider communication. Among oncology patients, studies demonstrate that electronic access promotes improved treatment adherence and symptom management and provides better continuity of care and patient satisfaction. In a previous audit, we found only 26% of our oncology patients had activated our EHR (EPIC) online patient portal. MyChart facilitates communication by allowing patients to see results and email providers through a secure network. We undertook this study to discover patient opinions about MyChart and barriers to wider adoption. Methods: A short, self-administered questionnaire was distributed to a convenience sample of patients in waiting areas or the infusion center of the outpatient oncology clinic. Results: 76/108 patients knew of MyChart; 32 did not. 54/76 (71.1%) of patients who knew of MyChart had used it. 81.5% of 54 users were very or somewhat satisfied with it. Users rated features of MyChart on a 5 point scale: certain their confidentiality is protected 4.7,ability to track tests 4.4,receiving faster answers 3.0,and ease of contacting providers 2.8. 21 non-users gave several reasons for not using MyChart: preference to speak with a live person 38.1%, discomfort with the internet 23.8%, not having internet 19.0%, concern about personal information on the internet 14.3%, and too complicated 9.5%. Among 32patients not previously aware of MyChart, 43.7% said they would definitely or probably start using it.56.3% thought MyChart would make it easier to contact providers and 53.1%cited convenience over telephone.However, 28.1%,preferred speaking to a live person; 12.5% were uncomfortable with the internet, and 9.4% expressed concern with their information on the internet. Conclusions: In this sample, 50% of respondents used MyChart. Patients using MyChart were generally satisfied, specifically with confidentiality and ability to monitor their care. Barriers to increased use included a desire to speak directly to providers and lack of internet skill or access. While those using MyChart were confident that it was secure and confidential, those not using expressed concern about this issue.

Custodian Controlled Data Repository - supporting the timely, easy and cost effective access to linked data

ABSTRACTObjectivesIn response to Data Custodian and Researcher's request to assist improving the timeliness and ease of data extractions, SA NT DataLink established the Custodian Controlled Data Repository (CCDR). Issues including conflicting work priorities and limited resources do prevent timely data extractions. SA NT DataLink, as a trusted third party enable Custodians to hold separate copies of their de-identified content data ready for timely release. The CCDR is opt-in for Custodians. Its key strength being the data remains under the control of participating Custodians, with Custodians updating and correcting their data. SA NT DataLink staff are work with Data Custodians to clean, standardise, update and prepare data in advance of anticipated approvals, including spatial enabled GIS variables. SA NT DataLink staff work under the direction of the Data Custodians, taking responsibility for preparing the data extractions required for the approved project.
 ApproachThe SA NT DataLink Custodian Controlled Data Repository (CCDR) takes advantage of the Secure Unified Research Environment (SURE), which is a secure remote access data laboratory operated by the Sax Institute in Sydney Australia. Using thin client and two-factor authentication, Data Custodians from South Australia and across Australia are able to securely store and maintain de-identified copies of their content data in SURE, ready for standardisation, quality review, and more timely release for approved use and data linkage projects.
 ResultsThe CCDR functional diagram provides an understanding of the data flow and processes that support more timely, easy and cost effective collation and provision of de-identified and privacy protected data. The Curated Gateway feature of SURE manages all the data coming into and being released from the Repository. Agreed regular updates of Data Custodian's data is able to be stored into their sub-directory, with access to the sub-directory managed by authentication and passwords. The SA NT DataLink Analysts is able to perform the role of data integrator for approved projects and use, also running privacy protecting algorithms and verification of the data being provided against the approvals.
 ConclusionThe CCDR securely stores the de-identified data ready for it to be integrated and released to Researchers. Use of secure remote access technologies allows Data Custodians to maintain control of their preloaded and pre-cleaned data in CCDR. In doing so this allows Custodians to authorise the use, from which SA NT DataLink staff dedicated to working only in the CCDR, integrate and release the data in a more timely manner.

Learning from a distance: high school students’ perceptions of virtual presence, motivation, and science identity during a remote microscopy investigation

ABSTRACTThrough partnerships with scientists, students can now conduct research in science laboratories from a distance through remote access technologies. The purpose of this study was to explore factors that contribute to a remote learning environment by documenting high school students’ perceptions of science motivation, science identity, and virtual presence during a remote microscopy investigation. Exploratory factor analysis identified 3 factors accounting for 63% of the variance, which suggests that Science Learning Drive (students’ perception of their competence and performance in science and intrinsic motivation to do science), Environmental Presence (students’ perception of control of the remote technology, sensory, and distraction factors in the learning environment, and relatedness to scientists), and Inner Realism Presence (students’ perceptions of how real is the remote programme and being recognised as a science-oriented individual) were factors that contribute to a student’s experience during a remote investigation. Motivation, science identity, and virtual presence in remote investigations are explored.

Students as Virtual Scientists: An exploration of students' and teachers' perceived realness of a remote electron microscopy investigation

Remote access technologies enable students to investigate science by utilizing scientific tools and communicating in real-time with scientists and researchers with only a computer and an Internet connection. Very little is known about student perceptions of how real remote investigations are and how immersed the students are in the experience. This study, conducted with high school students and their teachers, explored the impact of students' perception of ownership and virtual presence during a remote investigation using a scanning electron microscope. Students were randomly assigned to one of two treatment groups: students able to select their own insect to use during the remote investigation, and students that did not select their own insects to view during the remote investigation. The results of this study showed that students in the experimental group who had choice and ownership of their insect reported being more present (less distracted) during the remote investigation than students in the control group, whereas students in the control group reported controlling the technology was easier than the experimental group. Students indicated the remote investigation was very real; however, the teachers of these students were less likely to describe the investigation as being real. The results of this study have practical implications for designing remote learning environments.
