Dernayka, Aya, Michel-Ange Amorim, Roger Leroux, Lucas Bogaert, and René Farcy. "Tom Pouce III, an Electronic White Cane for Blind People: Ability to Detect Obstacles and Mobility Performances." Sensors 21, no. 20 (October 15, 2021): 6854. http://dx.doi.org/10.3390/s21206854.
Abstract:
We present a protocol for evaluating the efficiency of an electronic white cane for improving the mobility of blind people. The electronic cane used during the test is the Tom Pouce III, made of LIDAR sensors (light detection and ranging) with tactile feedback. The protocol comprises two parts. The first part, the “detection test”, evaluates the efficiency of the sensors in the Tom Pouce III for detecting the obstacles found in everyday life (thin and large poles, apertures) under different environmental conditions (darkness, sun light, rain). The second part of the test, the “mobility test”, compares the ability of blind participants to cross a 25 m path by avoiding obstacles with the simple white cane and the electronic cane. The 12 blind participants had between 2 and 20 years of experience of everyday usage of Tom Pouce devices. The results show a significant improvement in the capacity to avoid obstacles with the electronic cane relative to the simple white cane, and there was no speed difference. There was no correlation between the results and the years of experience of the users.

Abstract:
The monitoring of visually impaired people is important in order to help them to travel safely. Then, many research works implement some travel aids. The proposed techniques are mostly based on the use of a white cane. This work introduces an electronic white cane based on sensors' technology. The proposed electronic cane helps its user to detect obstacles within two meters on the ground or in height. Once the obstacle is detected, the system sends vocal instructions via a Bluetooth headset to alert the person concerned. The ultrasonic and infrared sensors have been mounted on the white cane in order to provide it with the necessary intelligence. A raspberry pi performs the processing of the data. The proposed system also suggests using a mobile application to track the visually impaired in real-time. This application has a function that allows you to trace the visual patient's route. This is important to detect the possible cause of damage to patients during their travels. We use Python as programming language for electronic devices. The mobile application is Android. Though, the WEB application is a REST API developed using Python and NodeJs. The system is implemented and tested. The result shows the efficacity of the proposed system.

Abstract:
Background Several technology-assisted aids are available to help blind and visually impaired people perform their daily activities. The current research uses the state-of-the-art technology to enhance the utility of traditional navigational aids to produce solutions that are more reliable. In this regard, a white cane is no exception, which is supplemented with the existing technologies to design Electronic Travel Aids (ETAs), Electronic Orientation Aids (EOAs), and Position Locator Devices (PLDs). Although several review articles uncover the strengths and limitations of research contributions that extend traditional navigational aids, we find no review article that covers research contributions on a technology-assisted white cane. The authors attempt to fill this literature gap by reviewing the most relevant research articles published during 2010–2017 with the common objective of enhancing the utility of white cane with the existing technology. Methods The authors have collected the relevant literature published during 2010–17 by searching and browsing all the major digital libraries and publishers’ websites. The inclusion/exclusion criteria were applied to select the research articles that are relevant to the topic of this review article, and all other irrelevant papers were excluded. Among the 577 (534 through database searching and 43 through other sources) initially screened papers, the authors collected 228 full-text articles, which after applying exclusion/inclusion criteria resulted in 36 papers that were included in the evaluation, comparison, and discussion. This also includes research articles of commercially available aids published before the specified range. Results The findings show that the research trend is shifting towards developing a technology-assisted white cane solution that is applicable in both indoor and outdoor environments to aid blind users in navigation. In this regard, exploiting smartphones to develop low-cost and user-friendly navigation solution is among the best research opportunities to explore. In addition, the authors contribute a theoretical evaluation framework to compare and evaluate the state-of-the-art solutions, identify research trends and future directions. Discussion Researchers have been in the quest to find out ways of enhancing the utility of white cane using existing technology. However, for a more reliable enhancement, the design should have user-centric characteristics. It should be portable, reliable, trust-worthy, lightweight, less costly, less power hungry, and require minimal training with special emphasis on its ergonomics and social acceptance. Smartphones, which are the ubiquitous and general-purpose portable devices, should be considered to exploit its capabilities in making technology-assisted white cane smarter and reliable.

Abstract:
Purpose The reduced ability of eyes to see clearly even with the use of glasses is known as the state of visual impairment. Among the many challenges faced, outdoor travel is one of them requiring to travel through surfaces, which has potholes and bumps. Design/methodology/approach The depth of the pothole and height of the bump is also conveyed to the user through different vibration pattern of various intensity. With available electronic travel aids, the visually impaired persons are still more inclined to rely on their white cane than carrying additional equipment for obstacle avoidance. In the system, all the components can be attached to the white cane, requiring no additional device to carry. Findings Upon experimentation with different obstacle types, the system obtained a 24.88% higher score in comparison to normal walking cane. A comparison with the state of the art available systems is also provided. Originality/value Moreover, the accuracy of the assistive cane can be heavily degraded if the cane is not properly held by the user. To restrict the user to hold the cane in only required orientation an alignment sensing switch is also proposed, which is missing in the current available literature.

Abstract:
Navigation aid is important for the visually impaired person to travel safely. A white cane is normally used to detect obstacles in the persons path but it is limited in its detecting ability as it can only detect obstacles around the length of the cane and is unable to detect moving or overhanging objects. Many types of navigational aids are being developed using ultrasonic sensors to assist the visually impaired to detect obstacles and they are known as Electronic Travel Aids. This paper is focused on studying the influence of acoustical absorbing material on the obstacle detection angle of an ultrasonic sensor. Results showed that a tube lined with acoustical absorbing material attached to the sensor is able to narrow the detection angle for more precise obstacle detection.

Abstract:
We developed a robot that can guide visually impaired people and elderly people as they walk around in large hospitals. In relation to this, a previous report described the structure of a guidance robot and the comparison of its use with that of a white cane. It was shown that with the use of the robot, participants could move more easily, safely, and confidently than with a white cane. However, to solve the problems encountered with the use of the previous robot, a new guidance robot was fabricated. This paper describes the structure of the new robot and the results of the demonstration examination of the robot in the Kanagawa Rehabilitation Center. The robot navigates to reach a destination set by using the touch panel, whereas velocity depends on the force exerted by the user on the robot. The questionnaire answered by the participants were evaluated using the system usability scale, which showed that the acceptability range of the robot is “Acceptable” and its usability is high.

Sensors 20, no. 20 (October 15, 2020): 5821. http://dx.doi.org/10.3390/s20205821.
Abstract:
This paper presented the assessment of cognitive load (as an effective real-time index of task difficulty) and the level of brain activation during an experiment in which eight visually impaired subjects performed two types of tasks while using the white cane and the Sound of Vision assistive device with three types of sensory input—audio, haptic, and multimodal (audio and haptic simultaneously). The first task was to identify object properties and the second to navigate and avoid obstacles in both the virtual environment and real-world settings. The results showed that the haptic stimuli were less intuitive than the audio ones and that the navigation with the Sound of Vision device increased cognitive load and working memory. Visual cortex asymmetry was lower in the case of multimodal stimulation than in the case of separate stimulation (audio or haptic). There was no correlation between visual cortical activity and the number of collisions during navigation, regardless of the type of navigation or sensory input. The visual cortex was activated when using the device, but only for the late-blind users. For all the subjects, the navigation with the Sound of Vision device induced a low negative valence, in contrast with the white cane navigation.

Abstract:
One of the challenges faced by the blind to achieve optimum mobility is obstacles detection and avoidance. The traditional aid is the mobility white cane, but nowadays, there are also electronic travel aids. However, none of them is widely used. The eBAT (electronic Buzzer for Autonomous Travel) has been designed to provide protection and easy usage, interacting with a user’s mobile phone. To improve its performance, a usage test was carried out by 25 totally blind users divided by sex, age range and autonomy in mobility. The main results are that the eBAT gives a reduction in the involuntary contacts but also decreases the walking speed. There are differences between sex, age and mobility groups but with limited statistical significance, and there are also some correlations between variables.

Abstract:
As engineering skills becomes a commodity, electrical engineers’ programs are urged to adapt their pedagogical strategies do better prepared their graduates. The 21st century engineers are expected to have a strong technical background while being capable to work with people with different kinds of intellectual and social capitals, and to have a high level of cognitive flexibility. This article reports on the application of an information appropriation method, adopted by the Department of Electrical Engineering at PUC-Campinas, where activities on extension projects are simultaneously conducted along with the regularly schedule classes. The study case is related to the coplanning and cocreation of a technological white cane (proof of connect) between electrical engineering students, social technicians and the visually impaired. In the present case, the technicians were led to reinterpret, adapt and reinvent technology while contributing to the design and build of a low cost adaptive electronic sensing aid attachable to a white cane. The collaborative method, applied during conversation rounds, is based on a virtuous cyclic process which includes steps like information capture, validation, guidance and feedback. The engineering students, on the other hand, have the opportunity to develop their communication, analysis and interpretation skills in a way not available in the classroom. They also experience solving conflict situations and find creative uses and applications for they knowledge not otherwise foreseen. The participating students transformed information into knowledge through a dialogical experience with people having a contrasting technological background to its own. Through this experience the engineering graduates emerged with a greater sense of responsibility with the society and a better understanding of what means to be an engineer. Participation in the Extension Project also brought up several opportunities of professional recognition by the technicians and the visual impaired themselves, which stimulated the students do achieve better performance in the course.

Abstract:
This paper documents the design, implementation and evaluation of the Unfolding Space Glove—an open source sensory substitution device. It transmits the relative position and distance of nearby objects as vibratory stimuli to the back of the hand and thus enables blind people to haptically explore the depth of their surrounding space, assisting with navigation tasks such as object recognition and wayfinding. The prototype requires no external hardware, is highly portable, operates in all lighting conditions, and provides continuous and immediate feedback—all while being visually unobtrusive. Both blind (n = 8) and blindfolded sighted participants (n = 6) completed structured training and obstacle courses with both the prototype and a white long cane to allow performance comparisons to be drawn between them. The subjects quickly learned how to use the glove and successfully completed all of the trials, though still being slower with it than with the cane. Qualitative interviews revealed a high level of usability and user experience. Overall, the results indicate the general processability of spatial information through sensory substitution using haptic, vibrotactile interfaces. Further research would be required to evaluate the prototype’s capabilities after extensive training and to derive a fully functional navigation aid from its features.

Abstract:
Visually Impaired (VI) people generally face difficulties during their pedestrian commute, when forced on to side-walks cluttered with vendors, animals and other obstacles. No single system can comprehensively cover all of their mobility needs. The proposed system intends to provide smart electronic aid for the VI which is appropriate to complement their white cane using the principles of the IoT. It detects any low-lying obstacles on its course and alerts the user to them and also uses Global Positioning System (GPS) technology which is a component of any smart phone, to pinpoint the VI's location when necessary. A feedback system, which is essentially a simple auditory circuit, which alarms the user of any obstacle, and informs priory designated guardians about the VI's current whereabouts, done by transmitting the coordinates of VI to a registered mobile number fed into an Android Application.

Electronics 10, no. 14 (July 6, 2021): 1619. http://dx.doi.org/10.3390/electronics10141619.
Abstract:
For most visually impaired people, simple tasks such as understanding the environment or moving safely around it represent huge challenges. The Sound of Vision system was designed as a sensory substitution device, based on computer vision techniques, that encodes any environment in a naturalistic representation through audio and haptic feedback. The present paper presents a study on the usability of this system for visually impaired people in relevant environments. The aim of the study is to assess how well the system is able to help the perception and mobility of the visually impaired participants in real life environments and circumstances. The testing scenarios were devised to allow the assessment of the added value of the Sound of Vision system compared to traditional assistive instruments, such as the white cane. Various data were collected during the tests to allow for a better evaluation of the performance: system configuration, completion times, electro-dermal activity, video footage, user feedback. With minimal training, the system could be successfully used in outdoor environments to perform various perception and mobility tasks. The benefit of the Sound of Vision device compared to the white cane was confirmed by the participants and by the evaluation results to consist in: providing early feedback about static and dynamic objects, providing feedback about elevated objects, walls, negative obstacles (e.g., holes in the ground) and signs.

Abstract:
To achieve optimal mobility, visually impaired people have to deal with obstacle detection and avoidance challenges. Aside from the broadly adopted white cane, electronic aids have been developed. However, available electronic devices are not extensively used due to their complexity and price. As an effort to improve the existing ones, this work presents the design of a low-cost aid for blind people. A standard low-cost HC-SRF04 ultrasonic range is modified by adding phase modulation in the ultrasonic pulses, allowing it to detect the origin of emission, thus discriminating if the echo pulses come from the same device and avoiding false echoes due to interference from other sources. This improves accuracy and security in areas where different ultrasonic sensors are working simultaneously. The final device, based on users and trainers feedback for the design, works with the user’s own mobile phone, easing utilization and lowering manufacturing costs. The device was tested with a set of twenty blind persons carrying out a travel experiment and satisfaction survey. The main results showed a change in total involuntary contacts with unknown obstacles and high user satisfaction. Hence, we conclude that the device can fill a gap in the mobility aids and reduce feelings of insecurity amongst the blind.

Abstract:
Environment perception is crucial for the safe navigation of vehicles and robots to detect obstacles in their surroundings. It is also of paramount interest for navigation of human beings in reduced visibility conditions. Obstacle avoidance systems typically combine multiple sensing technologies (i.e., LiDAR, radar, ultrasound and visual) to detect various types of obstacles under different lighting and weather conditions, with the drawbacks of a given technology being offset by others. These systems require powerful computational capability to fuse the mass of data, which limits their use to high-end vehicles and robots. INSPEX delivers a low-power, small-size and lightweight environment perception system that is compatible with portable and/or wearable applications. This requires miniaturizing and optimizing existing range sensors of different technologies to meet the user’s requirements in terms of obstacle detection capabilities. These sensors consist of a LiDAR, a time-of-flight sensor, an ultrasound and an ultra-wideband radar with measurement ranges respectively of 10 m, 4 m, 2 m and 10 m. Integration of a data fusion technique is also required to build a model of the user’s surroundings and provide feedback about the localization of harmful obstacles. As primary demonstrator, the INSPEX device will be fixed on a white cane.

Abstract:
The modern battlefield demands that soldiers endure rough terrain and weather while carrying all necessary items for their mission. These necessities include their food, water, ammunition and mission essentials, typically electronics. In order to give the troops the most capability while in the field, the efficiency and dependability of electronics is paramount. Key to the requirements definition for mission electronics is Size, Weight and Power - Cost, commonly known as the acronym SWAP-C. In addition to satisfying the SWAP-C requirements, all mission electronics need proven reliability since lives are at stake. Major defense systems in the past have lasted 30+ years. With this in mind, systems for tomorrow are being designed to support the defense industry's need for reliability, longevity and upgrade compatibility. This talk will focus on SWAP-C and high reliability in electronics and packaging to support the defense industry for years to come.

Abstract:
Purpose – The purpose of this paper is to examine two research questions: first, How do users in different locations find Auburn University Electronic Theses and Dissertations (ETDs)? Second, do users in different locations interact differently with the collection and, if so, how? Design/methodology/approach – Google Analytics data for user visits, landing pages, and page views were separated into groups based on user location. Visits data were also correlated with source (referring web site), and landing pages and page views were grouped by type. Findings – Most local users came to the repository via Auburn University web pages. This group usually landed on the collection home page and used internal navigation pages to find what they needed. Submission page views showed that most ETD depositors were local. Most out-of-state users came to the repository via web search engines. This group usually landed directly on bibliographic information pages for individual ETDs. They used internal navigation pages less frequently than local users. Users located within the state but outside of the local area interacted with the collection in a way that was intermediate between these two groups. Practical implications – Institutions interested in improving repository access for depositors will probably find it helpful to focus on in-state usage reports, while institutions seeking to improve access for end-users should exclude in-state users from their assessments. Originality/value – This is the first detailed examination of ETDs usage published since 2001 and shows how filtering tools available in Google Analytics allow comparisons of user behavior based on location and source (referring web site).

Abstract:
Ummi shop is a company engaged in the sale of traditional cakes. The sales system used today is a conventional system, where the buyer must come directly to the Garsel Shop to see the products offered. With this system, it will take the consumer's time so that it is difficult to obtain information about the specifications of the product being offered. E-Commerce or in Indonesian, namely electronic commerce is the distribution, purchase, sale, marketing of goods and services through electronic systems such as the internet or television, www, or other computer networks. E-commerce can involve electronic funds transfer, electronic data exchange, automated inventory management systems, and automated data collection systems. At this time, Ummi Store has not used the e-commerce facility so that it is difficult to offer products to consumers who are outside the city. In addition, it can also have an impact that affects the product sales process, namely the ignorance of consumers who are outside the city of the existence of Ummi Shops. The process of selling the Ummi Store will only be carried out if there are consumers who come to the store, while many consumers who are outside the city cannot come or do not know the existence of the Ummi Store. To build this e-commerce system, the tools used to describe the system model are in the form of a data flow diagram (FlowMap), context diagrams, and Data Flow Diagrams (DFD), as well as in database design using a data dictionary and Entity Relationship Diagram (ERD). With the existence of e-commerce is expected to make it easier for consumers to obtain information about product specifications offered by Ummi Stores. Make it easy for Ummi shops to offer or sell their products to consumers who are outside the city. Consumers who are outside the city can find out the existence of Ummi stores by using this e-commerce service and can order without having to come to the store. Make it easy for consumers to process payments because there are several options in the payment process. With a good product data processing or management system that is equipped with security, it will support the performance of the system.

Abstract:
The structural stabilities and electronic properties of singlet and triplet states C 24X12 heterofullerenes where X = B , Al , C , Si , N , and P are probed at the B3LYP/6-31+G* level of theory. Vibrational frequency calculations show that all of the systems are true minima. The calculated binding energies of heterofullerenes show C 24 B 12 and C 24 N 12 as the most stable heterofullerenes by 6.10 eV/atom and 5.63 eV/atom, respectively. While B , Al , N and P doping increase the conductivity of fullerene through decreasing its HOMO–LUMO gap, doping Si enhance its stability against electronic excitations via increasing the HOMO–LUMO gap. High charge transfer on the surfaces of our stable heterofullerenes, especially C 24 Al 12 followed by C 24 Si 12 and C 24 P 12, provokes further investigations on their possible application for hydrogen storage.

Abstract:
Blind people are often hampered in their mobility, while currently available assistive technology includes manual sticks and electronic mobility devices. Currently, the development of smart canes is still being carried out in many studies. Smart cane works by detecting the distance of the cane to obstacles in front of you. From detecting this distance, the response the user gets is generally in the form of vibrations and sounds from the buzzer. The sound provided by the buzzer cannot differentiate the distance between obstacles. Therefore, this study proposes the existence of additional sound playback responses to differentiate far, middle, and near obstacles. Apart from that, the design of the prototype refers to the shape of a flashlight. The smart cane is designed using an Arduini UNO microcontroller with a rechargeable battery power supply with three response components, namely two ISD 1820 modules connected to a speaker to detect long distances (201-300 cm) with a "Hati-hati" sound and medium distances (101-200 cm) with an "Awas" sound, as well as a buzzer and piezoelectric component in the form of a "beep" sound and vibration for close distances (1-100 cm) to obstacles. The result is that both the ultrasonic sensor and response components work according to design. Apart from that, the rechargeable battery supply feature and the implementation of the prototype design make it easier for users to store and use for daily activities.

Abstract:
Due to the increasing rates of chronic diseases and an aging population, the use of assistive devices for ambulation is expected to grow rapidly over the next several years. Instrumenting these devices has been proposed as a non-invasive way to proactively monitor changes in gait due to the presence of pain or a condition in outdoor and indoor environments. In this paper, we evaluated the effectiveness of a multi-sensor cane in detecting changes in gait due to the presence of simulated gait abnormalities, walking terrains, impaired vision, and incorrect cane lengths. The effectiveness of the instrumented cane was compared with the results obtained directly from a shank-mounted inertial measurement unit. Results from 30 healthy participants obtained while simulating gait abnormalities and walking over different terrains demonstrated the ability of the cane to reliably and effectively discriminate among these walking conditions. Moreover, the results obtained while walking with impaired vision and incorrect cane lengths indicate the ability of cane to detect changes in gait during these scenarios as well.

Abstract:
To analyze the contributions of the metal atoms to stabilize and synthesize the small cage-like carbon clusters, the configurations, electronic and magnetic characteristics of Mn-, Fe-, Co- and Ni-substituted C[Formula: see text] cage have been investigated using the PBE functional. The results demonstrate that the TM (TM[Formula: see text]=[Formula: see text]Mn, Fe, Co and Ni) substitution decreases the structural stability of the C[Formula: see text] cages, while increases the activity of the C[Formula: see text] cages. Electronic migrations between the TM atoms and C atoms are less. All the TM–C bonds of the TMC[Formula: see text] and TM2C[Formula: see text] clusters display covalent bond characters. The [Formula: see text] orbitals of TM atoms lose electrons, the [Formula: see text] and [Formula: see text] orbitals of TM atoms obtain electrons. The special distributions of the HOMO states of the TMC[Formula: see text] and TM2C[Formula: see text] clusters are mainly from the hybridization of the C [Formula: see text] orbitals and the TM [Formula: see text] orbitals. The Mn2C[Formula: see text] cages display the highest spin polarization.

Abstract:
Abstract After recent improvements brought the incremental compilation of large industrial test suites down to a few seconds, the first semantic checking of a project became one of the longest-running processes. As multi-core systems are now the standard, we derived a parallelisation using software engineering laws to improve the performance of semantic checking. Our measurements show that even an outdated laptop is fast enough for daily use. The performance improvements came without performance regressions, and we can’t expect additional massive benefits even from infinitely scaling Cloud resources. Companies should utilise cheaper machines that still o er enough performance for longer. This approach can help businesses increase profits, reduce electronic waste and promote sustainability while maintaining high-quality software development practices.

Journal of Nanoelectronics and Optoelectronics 17, no. 5 (May 1, 2022): 738–47. http://dx.doi.org/10.1166/jno.2022.3236.
Abstract:
We chose the first-principles method of density functional theory to study new carbon dioxide hydrate structures, obtain structure, electronic and optical properties. The results show that the side length and hydrogen bond length of the N-carbon dioxide hydrate water cage will not change significantly with CO2, the structure H binding energy is −0.247 eV that is the most stable. The binding energy and volume changes indicate that CO2 molecule has a very weak effect on the water cage which belongs to the van der Waals force, CO2 molecule can stabilize the water cage structure. The addition of CO2 molecule causes the bottom of the configuration’s conduction band to shift down and the band gap value decreases. The density of states of CO2 molecule in the hydrate shifted to the left while the density of states of the water cages did not change much, the s state electrons change slightly in the energy region of 5–15 eV. The N-carbon dioxide hydrate’s ability to store electromagnetic fields in the low frequency range is enhanced, it is weakened in the high frequency range. The microwave loss in the 2.5–25 eV frequency band increases and the reflectivity peaks at 9.06 eV.

Abstract:
A series of hybrid materials involving cage-like octaaminopropyl polyhedral oligomeric silsesquioxane and Polyvinyl alcohol(OAPS/PVA) were prepared via solution blending method. The hybrid systems were characterized by FT-IR, scanning electronic microscopy(SEM), energy dispersive X-ray(EDS), differential scanning calorimetry(DSC), thermogravimetry analysis(TGA) and tensile test. The results show that hydrogen bond interactions are formed between OAPS and PVA and OAPS has a good dispersion in PVA matrix. The glass transition temperature(Tg) of OAPS/PVA increases from 53°C to 61°C, while the melting temperature(Tm) decreases from 180°C to 173°C with increasing OAPS content from 0% to 12%. The thermal stability of PVA main chain is improved by the addition of OAPS and the residue ratio also increases. The tensile strength of OAPS/PVA decreases from 39MPa to 16MPa, while the elongation at break of hybrid films increases from 148% to 351%.

Abstract:
Iran in the 1970s was host to an array of electronic music and avant-garde arts. In the decade prior to the Islamic revolution, the Shiraz Arts Festival provided a showcase for composers, performers, dancers and theater directors from Iran and abroad, among them Iannis Xenakis, Peter Brook, John Cage, Gordon Mumma, David Tudor, Karlheinz Stockhausen and Merce Cunningham. A significant arts center, which was to include electronic music and recording studios, was planned as an outgrowth of the festival. While the complex politics of the Shah's regime and the approaching revolution brought these developments to an end, a younger generation of artists continued the festival's legacy.

Journal of Clinical Oncology 38, no. 15_suppl (May 20, 2020): e17588-e17588. http://dx.doi.org/10.1200/jco.2020.38.15_suppl.e17588.
Abstract:
e17588 Background: Clinical trials of sip-T predominately included white men (over 90%). Previously we explored outcomes with sip-T in white and black patients (pts) (Kantoff PW, NEJM 2010; Sartor AO, ASCO 2019, #5035). In this retrospective analysis of data from electronic medical record and practice management systems, we explored the hypothesis that Asian and white pts who receive sip-T for CRPC exhibit similar overall survival. Methods: Data came from > 100 US community urology practices, predominantly large urology group practice associations. White and Asian pts were matched based on 5 criteria: sip-T treatment year; treatment pattern for oral and sip-T; metastatic site (Bone v. Nodal v. Visceral); prostate-specific antigen (PSA) within 10%; and age at treatment. Parameters retrieved include those listed in the table. Overall survival (OS) was analyzed using Kaplan Meier (KM) methodology with Cox Proportional Hazards Modelling used to generate the hazard ratio (HR) with Asians as the reference. Descriptive summary statistics were generated for other parameters. Results: The analysis identified 102 white and 77 Asian pts; treatment ranged from 2012 to 2019 with 60% receiving sip-T after 2016, impacting the ability to examine long-term outcomes. Characteristics of the 2 groups were broadly similar, although more Asians had Gleason scores ≥8 than whites (Table). In the KM analysis, most pts were censored. While the KM survival curves separate around month 25, favoring Asian pts, the difference is not significant (HR, 0.69 [95% CI: 0.4, 1.4]; P = 0.277). Conclusions: These real-world data do not show a significant difference in OS between Asian and white men. Both groups exhibited relatively low median PSAs near 5 ng/mL, an observation correlated with longer OS in previous studies. [Table: see text]

Abstract:
The models of endofullerenes C 60 and C 82 with silver atom or diatomic silver are calculated with ab initio methods including the full geometry optimization. Ag @ C 60 is the bound system with positive binding energy while Ag 2@ C 60 is not bound because of strong geometrical strain. In Ag @ C 60 silver atom has the off-center position for the lowest energy model, and the whole structure reduces the symmetry from I h down to C 1. The endo-structures with the C 82 cage can exist with both mono- and diatomic silver interiors. Electronic charge is transferred from the carbon cage to silver.

Abstract:
The study aimed to identify the application of electronic supervision and the obstacles to its implementation from the perspective of the educational supervisors in the cities of Dammam and Khobar. To achieve the study objectives, the descriptive methodology was employed. The questionnaire was used to collect data from a sample of (134) female educational supervisors. The results showed that the application of electronic supervision achieved a high degree, where educational tasks ranked first, followed by administrative tasks, while the professional development dimension for female teachers came last in terms of the application of electronic supervision. The results also indicated the existence of obstacles to a high degree when applying electronic supervision ranked as followed: technical obstacles, human obstacles, and finally administrative obstacles. The study provides a number of recommendations such as preparing education offices and schools with the required devices and equipment that support the employment of electronic supervision, attracting female specialists in computer software to work in the education offices, adopting electronic portfolios for supervisors and teachers, and finally holding periodic meetings for the educational supervisors at the region level to discuss the latest technological developments.

Abstract:
We report the new structures of aluminum hydrides derived from the Al4 tetrahedral cages. We perform ab initio quantum chemical calculation for these new aluminum hydrides. Our calculation of binding energies of the new aluminum hydrides reveal that stability of these hydrides increases as more hydrogen atoms are adsorbed, while stability of Al-H bonds decreases. We also calculate electronic stress tensor to evaluate the chemical bonds of these hydrides. As a result, we find that the bonds of the Al4 tetrahedral cage are strengthened as more hydrogen atoms are adsorbed on the aluminum hydrides. Our calculation of the potential energy surfaces and the regional chemical potential show that hydrogen atoms are likely to adsorb on bridge site at first.

The objective was to study the effects of sugar cane molasses addition on the fermentation quality and tastes of alfalfa silage. Fresh alfalfa was ensiled with no additive (Control), 1% molasses (M1), 2% molasses (M2), and 3% molasses (M3) for 206 days. The chemical composition and fermentation characteristics of the alfalfa silages were determined, the microbial communities were described by 16S rRNA sequencing, and the tastes were evaluated using an electronic tongue sensing system. With the amount of added molasses (M), most nutrition (dry matter and crude protein) was preserved and water-soluble carbohydrates (WSC) were sufficiently used to promote the fermentation, resulting in a pH reduction from 5.16 to 4.48. The lactic acid (LA) content and LA/acetic acid (AA) significantly increased, indicating that the fermentation had turned to homofermentation. After ensiling, Enterococcus and Lactobacillus were the dominant genus in all treatments and the undesirable microbes were inhibited, resulting in lower propionic acid (PA), butyric acid (BA), and NH3-N production. In addition, bitterness, astringency, and sourness reflected tastes of alfalfa silage, while umami and sourness changed with the amount of added molasses. Therefore, molasses additive had improved the fermentation quality and tastes of alfalfa silage, and the M3 group obtained the ideal pH value (below 4.5) and the best condition for long-term preservation.

Abstract:
Background There have been many reports of electronic cigarette burns and lithium ion battery explosions leading to property and/or bodily damage, but there is a paucity of data about these injuries in the medical literature. We present a series of patients treated for electronic cigarette burns and lithium ion explosions and review the literature. Methods Patients treated for electronic cigarette burns between January 2012 and December 2016 were identified. Patients were included if they suffered injuries from either an electronic cigarette device or from batteries used in the devices. Data were collected on the mode of injury, depth, size, and location of the burn, whether or not they had any surgeries and length to recovery. Results Fourteen patients were treated for electronic cigarette burns between 2012 and 2016. Burn size ranged from <1% to 6% total body surface area. Most patients suffered burns to their thighs because the battery or device exploded in their pocket. The majority suffered partial thickness burns while four patients had full thickness burns. Three patients required excision and autografting, all of which were full thickness burns. The average time to recovery was 24.5 days. Conclusions Electronic cigarettes pose a new and unique risk to consumers. Lithium ion battery explosions can cause severe injury and significant burns requiring surgery. The incidence of e-cigarette burns are expected to increase as the number of users grow.

Abstract:
In engineering the pedagogical content of most formative programmes includes a significant amount of practical laboratory hands-on activity designed to deliver knowledge acquisition from actual experience alongside traditional face-to-face classroom based lectures and tutorials; this hands-on aspect is not always adequately addressed by current e-learning platforms.
An innovative approach to e-learning in engineering, named computer aided engineering education (CAEE) is about the use of computer aids for the enhanced, interactive delivery of educational materials in different fields of engineering through two separate but related components; one for classroom and another for practical hands-on laboratory work. The component for hands-on laboratory practical work focuses on the use of mixed reality (video-based augmented reality) tools on mobile devices/platforms.
This paper presents the computer aided engineering education (CAEE) implementation of a laboratory experiment in micro-electronics that highlights some features such as the ability to closely implement an existing laboratory based hands-on experiment with lower associated costs and the ability to conduct the experiment off-line while maintaining existing pedagogical contents and standards.

Abstract:
Electronic cigarettes are a type of electronic nicotine delivery system. In the United States, electronic cigarettes have surged in popularity since their introduction to the market in 2007. Health and safety concerns primarily have focused on e-liquid/aerosol composition and whether these devices represent a gateway versus lower risk alternative to conventional cigarettes. Furthermore, recent incidents have demonstrated the potential for significant orofacial injury caused by device explosion while in use. Herein we report a case of a 20-year-old male who sustained oral burns, lacerations, and tooth loss when an electronic cigarette exploded in his mouth shortly after he charged the battery. Only seven other cases of trauma from intraoral electronic cigarette explosions have been reported in the scientific literature to date, although several similar incidents also have been reported by the news media. Treatment of such patients often requires a multidisciplinary approach. Design/manufacturing issues and improper handling may cause an increase in internal battery temperature. An investigation by the United States Fire Administration concluded that user education may aid in preventing some electronic cigarette explosions, and safety design improvements also could help. Although some studies and authorities support the use of electronic cigarettes for tobacco cessation and harm reduction, recent reports of electronic cigarette explosions raise important safety concerns and point to the need for further studies.

Abstract:
BACKGROUND: Identifying obstacles and potholes in the pathway of the visually impaired have received much attention. While much has been done on the detection of obstacles, in the design of electronic mobility aids, much more is needed to be done on the detection of holes and drop-offs, especially those that are affordable and hands-free. This paper therefore considers the development of a wearable electronic mobility aid. METHODS: The developed system is based on the multisensor fusion approach of detection which combined three techniques, namely: a source of laser light, a camera and an ultrasonic sensor. A red line generating laser source is used to project a straight line and this is captured by the camera. The red line is deformed differently on coming in contact with holes or standing obstacles. The pattern of deformation is then extracted for obstacle and pothole recognition. The visibility of laser light is greatly reduced when the scene is extremely illuminated, so this is complemented with edge detection. The edge detection uses edges in the identification of holes and obstacles. This is combined with ultrasonic sensing, so that the presence of obstacles can be differentiated from that of holes. The outcome of detection and the distance of obstacles from the blind are relayed via an audio cue. REDULTS: Its evaluation showed better performance compared to the guide cane. It showed a reduction in collision rate by 83.25% and reduction in falling rate by 84.62%. The device received good acceptability from the users.
