Yeting Guo, Fang Liu, Zhiping Cai, Nong Xiao, Ziming Zhao
Smart sensor-equipped mobile devices sense, collect, and process data generated by the edge network to achieve intelligent control, but such mobile devices usually have limited storage and computing resources. Mobile cloud storage provides a promising solution owing to its rich storage resources, great accessibility, and low cost. But it also brings a risk of information leakage. The encryption of sensitive data is the basic step to resist the risk. However, deploying a high complexity encryption and decryption algorithm on mobile devices will greatly increase the burden of terminal operation and the difficulty to implement the necessary privacy protection algorithm...

At- (astatide) is commonly expected to be the heaviest halide in the halogen group. However, there is no proof for the existence of this -1 charged species. Furthermore, investigations with astatine are restricted by its specific radioactive properties, which entail working at ultratrace concentrations (typically less than 10-10 M). In this work, an especially built electromigration device is applied to obtain information about the charge/size ratio characterizing an ion in aqueous solution. An anionic At species is observed in reducing conditions...

The aim of this study was to report on 2 patients in whom metal-on-metal (MOM) facet replacements failed, with subsequent positive findings on allergy testing. Motion-preserving devices have been used with limited success when instrumentation is indicated in the mobile spine. MOM-bearing surfaces in orthopedics were developed to increase implant longevity, yet have been associated with numerous adverse outcomes, including local tissue reactions, pseudotumors, metallosis, and the need for revision surgery. Five patients with spinal stenosis and low-grade spondylolisthesis were randomized to undergo facet replacement surgery with the ACADIA facet replacement system at the authors' institution...

BACKGROUND: In sports medicine, the interprofessional care of athletes has become a frequent practice. This type of care often involves different interventions used among professionals. One common intervention prescribed is roller massage (RM) or self-myofascial release. The trends in the use of RM among allied health professionals is non-existent. The surveillance of such responses has not been documented. PURPOSE: To survey and document responses in the knowledge, clinical application, and use of RM devices among allied health professionals in the United States...

Ambient ionization mass spectrometry (AI-MS), the ionization of samples under ambient conditions, enables fast and simple analysis of samples without or with little sample preparation. Due to their simple construction and low resource consumption, plasma-based ionization methods in particular are considered ideal for use in mobile analytical devices. However, systematic investigations that have attempted to identify the optimal configuration of a plasma source to achieve the sensitive detection of target molecules are still rare...

Extreme stresses can be produced in nanoscale structures, a feature which has been used to realize enhanced materials properties, such as the high mobility of silicon in modern transistors. Here we show how nanoscale stress can be used to realize exceptionally low mechanical dissipation, when combined with "soft-clamping" - a form of phononic engineering. Specifically, using a non-uniform phononic crystal pattern, we colocalize the strain and flexural motion of a free-standing Si3 N4 nanobeam. Ringdown measurements at room temperature reveal string-like modes with quality ( Q ) factors as high as 800 million and Q × frequency exceeding 1015 Hz...

BACKGROUND: Regarding electromagnetic fields from mobile communication technologies, empirical studies have shown that precautionary information given to lay recipients increases their risk perceptions, i.e. the belief that electromagnetic fields are dangerous. Taking this finding one step further, the current study investigates whether precautionary information also leads to higher symptom perceptions in an alleged exposure situation. Building on existing research on nocebo responses to sham electromagnetic fields, an interaction of the precautionary information with personality characteristics was hypothesised...

A common concern in smart cities is the focus on sensing procedures to provide city-wide information to city managers and citizens. To meet the growing demands of smart cities, the network must provide the ability to handle a large number of mobile sensors/devices, with high heterogeneity and unpredictable mobility, by collecting and delivering the sensed information for future treatment. This work proposes a multi-wireless technology communication platform for opportunistic data gathering and data exchange with respect to smart cities...

Crowd sensing is a powerful tool to map and predict interests and events. In the future, it could be boosted by an increasing number of connected vehicles sharing information and intentions. This will be made available by on board wireless connected devices able to continuously communicate with other vehicles and with the environment. Among the enabling technologies, visible light communication (VLC) represents a low cost solution in the short term. In spite of the fact that vehicular communications cannot rely on the sole VLC due to the limitation provided by the light which allows communications in visibility only, VLC can however be considered to complement other wireless communication technologies which could be overloaded in dense scenarios...

BACKGROUND: Although fingertip injuries account for a high proportion of trauma patients, the correct surgical approach is still debated. This prospective study compares the traditional conservative approach and a new treatment based on the injection of liposuction aspirate fluid (LAF). METHODS: 40 consecutive patients with a fingertip injury were dichotomized into group A (control group: conservative approach) and B (treatment group). Group B underwent liposuction, followed by filtration of the lipoaspirate in a closed device (MyStemEvo®kit), allowing the nonenzymatic separation of LAF, which was then injected at injured site...

Children commonly use mobile devices at pediatric office visits. This practice may affect patient-provider interaction and undermine accuracy of developmental surveillance. A randomized, provider-blinded, controlled trial examined whether a policy prohibiting mobile device use in a pediatric clinic improved accuracy of pediatricians' developmental surveillance. Children, aged 18 to 36 months, were randomized to device-prohibited (intervention; n = 58) or device-allowed (control; n = 54) groups. After a 30-minute well-visit, development was evaluated as "normal," "borderline," or "delayed" in 5 categories using the Ages and Stages Questionnaire (ASQ-3)...

A series of peripherally dicyano-, tricyano- and tetracyano- substituted subphthalocyanines (SubPcs) have been prepared via microwave-assisted palladium-mediated cyanation of iodinated precursors. The introduction of π-acceptor cyano groups in the macrocycle clearly influences its electronic and redox properties, which are dependent on the number and relative position of these substituents. Additional functionalization of the SubPcs periphery with electron-donating or electron-withdrawing groups allows for a further fine tune of their features, leading to intensely-absorbing strong-electron-acceptor panchromatic dyes with low-lying LUMO energy levels...
