Abstract Continuous imaging of cardiac functions is highly desirable for the assessment long-term cardiovascular health, detection acute dysfunction and clinical management critically ill or surgical patients 1–4 . However, conventional non-invasive approaches to image function cannot provide continuous measurements owing device bulkiness 5–11 , existing wearable devices can only capture signals on skin 12–16 Here we report a ultrasonic continuous, real-time direct assessment. We introduce...
Serial assessment of the biomechanical properties tissues can be used to aid early detection and management pathophysiological conditions, track evolution lesions evaluate progress rehabilitation. However, current methods are invasive, only for short-term measurements, or have insufficient penetration depth spatial resolution. Here we describe a stretchable ultrasonic array performing serial non-invasive elastographic measurements up 4 cm beneath skin at resolution 0.5 mm. The conforms human...
Abstract Electronic patches, based on various mechanisms, allow continuous and noninvasive monitoring of biomolecules the skin surface. However, to date, such devices are unable sense in deep tissues, which have a stronger faster correlation with human physiological status than those Here, we demonstrate photoacoustic patch for three-dimensional (3D) mapping hemoglobin tissues. This integrates an array ultrasonic transducers vertical-cavity surface-emitting laser (VCSEL) diodes common soft...
Depth-of-interaction (DOI) capability is important for achieving high spatial resolution and sensitivity in dedicated organ small animal positron emission tomography (PET) scanners. The dual-ended readout one of the common methods that can achieve good DOI resolution. aim this study to evaluate a detector based on silicon photomultiplier (SiPM) TOFPET2 application-specific integrated circuit (ASIC). 4 lutetium–yttrium oxyorthosilicate (LYSO) units, each unit contained 6 LYSO crystals,...
Recent progress with Cadmium Zinc Telluride (CZT) radiation sensors grown by the traveling heater method (THM) at Kromek is reported. Large volume monolithic pixelated detectors, 40×40×15 mm
The tumor-involved regions of head and neck cancer (HNC) have complex anatomical structures vital physiological roles. As a consequence, there is need for high sensitivity spatial resolution dedicated HNC PET scanner. purpose this article to evaluate optimize system design that includes detecting materials geometries. For the material, two scanners with same two-panel geometry based on cadmium zinc telluride (CZT) lutetium-yttrium oxyorthosilicate (LYSO) were evaluated. geometry, four CZT...
The effectiveness of cycloplegia in delaying the progression myopia and its application refractive examination children have been extensively studied, but there are still few studies on effects atropine/tropicamide ocular biological parameters. Therefore, purpose this study was to explore children's parameters different age groups differences between them.This a prospective observational which all school were examined for dioptres outpatient clinic, 1% atropine or tropicamide used treatment....
In this paper we experimentally demonstrate a femtosecond all-polarization- maintaining laser amplifier in an all-fiber scheme, which consists of mode-locked oscillator and two-stage amplifier. A hybrid method dispersion compensation is proposed based on fiber two Bragg gratings with different group velocity dispersion. The output pulse from the 57 fs average power 150 mW repetition rate 60 MHz, corresponding to peak 38.6 kW. By evaluation shaping, one third was compensated by pair gratings,...
Near-space airships are high-end that being vigorously developed in the aerospace industry. It has important application value telecommunication, surveillance, monitoring, remote sensing, and exploration fields. The envelope is key component provides lift to airship. Online monitoring of status critical ensuring airship performance, safety, reliability. However, online 3D shape strain still a challenging task. A hybrid multi-core single-core fiber-optic method with temperature...
The traditional integrated guidance and control (IGC) method only considers the coupling between attitude loop loop. When intercepting a target with high maneuver or traversal speed, semi-strapdown missiles needs large adjustment to get enough seeker is likely lose This paper coordinator stable tracking. First, IGC model containing loop, tracking established. uncertainties of aerodynamic parameters are also considered. Then, back-stepping proposed based on active disturbance rejection...
In this paper, a mathematical model of dynamic task schedule based on an anytime algorithm is proposed. The factors that affect the deadline opponents are studied. We construct according to minimize surplus threat and maximize attack value. By using time utility can give decisions timely coordinately for known unknown targets. Balancing decision efficiency, quickly. applied real-time weapon-target assignment (DWTA) problem. simulation results show efficiently DWTA problems.
The observation vectors in traditional coarse alignment contain random noise caused by the errors of inertial instruments, which will slow down convergence rate. To solve above problem, a real-time reduction method, sliding fixed-interval least squares (SFI-LS), is devised to depress vectors. In this paper, square improved approach, applied for reduction. order achieve better-performed alignment, proposed method utilized de-noise First, principles SFI-LS algorithm and are devised. A...
BGP monitors are currently the main data resource of AS-level topology measurement, and integrity measurement result is limited to location such monitors. However, there no work conduct a comprehensive study range results for single monitor. In this paper, we take first step describe observed each To that end, investigate construction theoretical up-limit measured monitor based on valley-free model, then evaluate individual parts by comparing with actually data. We find that: 1) more than...
