Microwave-induced thermoacoustic imaging (MTAI) has been widely used in biomedical science, and the potential as an auxiliary measure for clinical diagnosis treatment. Recently, there are increasing interests using ultrashort microwave-pumped techniques to obtain high-efficiency, high-resolution images. However, traditional system can only provide uniform radiation a relatively small area, which limits their large field of view applications (such whole-breast imaging, brain imaging). To...
A novel vehicle localization and tracking methods are presented based on magnetic anomaly detection by distributed sensors. First, taking advantage of total field, in this article, we propose a field matching (TFM) method that is immune rotational vibrations to perform target localization. Instead directly inverting the nonlinear dipole equations, use TFM approach find suboptimal position, then apply linear Kalman filter tail after target. Because relationship between dynamics equations....
Fluxgate magnetometers have been widely applied in many fields, such as magnetic anomaly detection, e-compass, etc. In this work, a micro-fluxgate magnetometer based on the implementation of MEMS technology is proposed. The core fluxgate was fabricated by using an amorphous Co-based material, which shows good degree linearity below 0.5 Oe. Moreover, mixed-signal lock-in circuit designed to drive and capture signals.

Context: Irrigation, which serves a variety of purposes including antibacterial action, tissue dissolution, cleaning and chelating, plays centric role in the final success root canal treatment. Thus, more attention has been put on improvement development various irrigation techniques or systems. Aims: The aim present study was to compare efficacy chitosan MTAD for smear layer removal from through scanning electron microscopy (SEM). Settings Design: Thirty single-canal premolars were...
Microwave-induced thermoacoustic imaging (MTAI), combining the advantages of high contrast microwave and resolution ultrasonic imaging, is a potential candidate for breast tumor detection.
Microwave-induced thermoacoustic imaging (MTAI) is a potential nonionizing candidate for breast tumor detection due to its high contrast of tissue dielectric absorption and resolution ultrasonography. However, conventional MTAI systems need contact the targets through ultrasound-coupling medium efficient transmission signals. This major drawback applications such as navigation open surgeries, burns, ulcer testing. In this paper, we report Fabry–Pérot (FP) interference principle-based...
As the basis for generating multi-particle quantum correlations, inter-particle interaction plays a crucial role in collective phenomena, phase transitions, and information processing. It can profoundly alter band structure of many-body systems give rise to exotic topological phenomena. Conventional pumping, which has been well demonstrated driven linear or noninteracting systems, may break down presence strong interaction. However, interplay between topology could also induce emergent...

A procedure for the enhancement of alternating current field measurement (ACFM) detection performance is proposed based on a multi-parameter synergy analysis (MPSA) algorithm. Firstly, to gain maximised ACFM signal characteristics, wavelet base property matching adopted choose favourable bases. To this aim, following six properties should be considered: orthogonality, compact support, symmetry, discrete transform (DWT), vanishing moment and regularity. It found that applicable bases are...
Lead-based relaxor-PT single crystals of rhombohedral phase, such as Pb(Zn1/3Nb2/3)O3-PbTiO3 and Pb(Mg1/3Nb2/3)O3-PbTiO3, exhibit excellent piezoelectric properties are candidate active materials for high-performance underwater projectors. However, their low coercive field would cause depolarization under high ac drive field, making them unsuitable power applications. The present work investigates the effect axial compressive stress on phase transition behaviors [011]-poled 32-mode...
This paper outlines a general beamline smoothing concept based on the use of First Principle Component analysis. Beamline is commonly used for detection blunders in positioning beam elements and to provide smooth particle path with fewest adjustments individual components. It also provides data assessment achieved quality.
A series of beam tests using TRISTAN Accumulation Ring (AR) was dedicated to verify the feasibility RF system and other components planned for KEKB, B Factory project at KEK. In this paper, we describe results on higher order mode (HOM) absorbers used superconducting cavities (SCC). The absorber manufactured by HIPping ferrite powder onto Cu tube. SCC operated stably with HOM's being damped, up total 4.2 kW absorbed through without any problem.
