Despite major advancements in mechanical circulatory support, the self-management (SM) for patients with a left-ventricular assist device (LVAD) remains complex and challenging for patients and their caregivers. We have developed a mobile phone application (VAD Care App) to organize and simplify the LVAD SM process. This article describes the development and feasibility study of the app as an SM tool for LVAD patients and caregivers requiring support from ventricular assist device (VAD) coordinators. The specific aim was to evaluate the app's acceptability and usability and the users' competency...

One-dimensional metal-oxide nanowires are regarded as important building blocks in nanoscale electronics due to their unique mechanical and electrical properties. In this work, p-type nickel oxide nanowires (NiO NWs) were fabricated by combining sol-gel and electrospinning processes. The polyvinylpyrrolidone (PVP) with 1,300,000 molecular weight was used as the polymer matrix to increase the viscosity of NiO precursor solution. The formation and properties of the as-spun NiO/PVP composite NWs before/after calcination treatment were investigated using various techniques...

BACKGROUND: Currently, inadequate wheelchair provision has forced many people with disabilities to be trapped in a cycle of poverty and deprivation, limiting their ability to access education, work and social facilities. This issue is in part because of the lack of collaboration among various stakeholders who need to work together to design, manufacture and deliver such assistive mobility devices. This in turn has led to inadequate evidence about intervention effectiveness, disability prevalence and subsequent costeffectiveness that would help facilitate appropriate provision and support for people with disabilities...

Background Through the concept of ageism, we highlight and explain how the society prejudices the elderly. WHO classifies 12 most common stereotypes pertaining to old age. Elderly people are being excluded from social life due to their chronological age rather than any actual reduced physical and/or mental ability. Some of these stereotypes are directly related to the (un)willingness and the ability of the elderly to use technology in everyday life. Objectives The study presented in this article aims to explain the phenomenon of technology use among elderly people who had had a stroke...

Mary B Alatise, Gerhard P Hancke
Using a single sensor to determine the pose estimation of a device cannot give accurate results. This paper presents a fusion of an inertial sensor of six degrees of freedom (6-DoF) which comprises the 3-axis of an accelerometer and the 3-axis of a gyroscope, and a vision to determine a low-cost and accurate position for an autonomous mobile robot. For vision, a monocular vision-based object detection algorithm speeded-up robust feature (SURF) and random sample consensus (RANSAC) algorithms were integrated and used to recognize a sample object in several images taken...

A high-mobility p-type organic semiconductor based on benzodithiophene and diketopyrrolopyrrole with linear alkylthio substituents (BDTS-2DPP) is used as a dual function interfacial layer to modify the interface of perovskite/2,2',7,7'-tetrakis(N,N'-di-p-methoxyphenylamine)-9,9'-spirobifluorene in planar perovskite solar cells. The BDTS-2DPP layer can remarkably passivate the surface defects of perovskite through the formation of Lewis adduct between the under-coordinated Pb atoms in perovskite and S atoms in BDTS-2DPP, and also shows efficient hole extraction and transfer properties...

Menghao Wu, Xiao Cheng Zeng
Atomically thin Bi2O2Se has been recently synthesized and it possesses ultra-high mobility (Nat Nanotech. 2017, 12, 530; Nano Lett. 2017, 17, 3021). Herein, we show first-principles evidence that Bi2O2Se and a related class of bismuth oxychalcogenides, such as Bi2O2S and Bi2O2Te, not only are novel semiconductors with ultra-high mobility but also possesses previously unreported ferroelectricity/ferroelasticity. Such a unique combination of semiconducting with ferroelectric/ferroelastic properties enables bismuth oxychalcogenides to potentially meet a great challenge, that is, integration of room-temperature functional non-volatile memories into future nanocircuits...

Wastewater-based epidemiology is an established approach for quantifying community drug use and has recently been applied to estimate population exposure to contaminants such as pesticides and phthalate plasticizers. A major source of uncertainty in the population weighted biomarker loads generated is related to estimating the number of people present in a sewer catchment at the time of sample collection. Here, the population quantified from mobile device-based population activity patterns was used to provide dynamic population normalized loads of illicit drugs and pharmaceuticals during a known period of high net fluctuation in the catchment population...

Rhinoplasty is a common procedure in cosmetic surgery all over the world. Patients desire enhancement of their facial beauty by the correction of preexisting nasal deformities. Precisely performed operations lead to better results, and enhancing technical accuracy accordingly results in more successful outcomes. Endoscopy helps us visualize the closed parts of the body with the aid of an illuminated optical device. The objective behind the present case series was to bring the advantages of open and closed rhinoplasty together by using endoscopic vision systems...

BACKGROUND: Sleep and sleep quality assessment by means of sleep stage analysis is important for both scientific and clinical applications. Unfortunately, the presently preferred method, polysomnography (PSG), requires considerable expert assistance and significantly affects the sleep of the person under observation. A reliable, accurate and mobile alternative to the PSG would make sleep information much more readily available in a wide range of medical circumstances. NEW METHOD: Using an already proven method, ear-EEG, in which electrodes are placed inside the concha and ear canal, we measure cerebral activity and automatically score the sleep into up to five stages...

BNCX monolayer as a kind of two-dimensional material has numerous chemical atomic ratios and arrangements with different electronic structures. Via calculations on the basis of density functional theory and Boltzmann transport theory under deformation potential approximation, the band structures and carrier mobilities of BNCX (x=1,2,3,4) nanosheets are systematically investigated. The calculated results show that BNC2-1 is a material with very small band gap (0.02 eV) among all the structures while other BNCX monolayers are semiconductors with band gap ranging from 0...

BACKGROUND: With the continuous and enormous spread of mobile technologies, mHealth has evolved as a new subfield of eHealth. While eHealth is broadly focused on information and communication technologies, mHealth seeks to explore more into mobile devices and wireless communication. Since mobile phone penetration has exceeded other infrastructure in low and middle-income countries (LMICs), mHealth is seen as a promising component to provide pervasive and patient-centered care. OBJECTIVES: The aim of our research work for this paper is to examine the mHealth literature to identify application areas, target diseases, and mHealth service and technology types that are most appropriate for LMICs...

Organic electronic devices fabricated on flexible substrates are promising candidates for applications in environments where flexible, light-weight and radiation hard materials are required. In this work, device parameters as threshold voltage, charge mobility and trap density of 13-Bis(triisopropylsilylethynyl)pentacene (TIPS-pentacene) based OTFTs have been monitored performing electrical measurements before and after irradiation by high-energy protons. The observed reduction of charge carrier mobility following irradiation can be only partially ascribed to the increased trap density...
