An electron tube with a Fabry-Perot resonator for the generation of millimeter and submillimeter waves, Ledatron, has been investigated both theoretically experimentally. Two different mode interactions, surface wave mode, were predicted found to exist. These two modes can be separated by proper selection mirror spacing in tube. oscillations have characteristics. In case oscillating frequency is tuned mainly variation spacing, that is, mechanical tuning predominant. On other hand, electronic...
Background: Neuromuscular electrical stimulation (NMES) is an alternative therapy for patients unable to perform sufficient voluntary exercises. This randomised crossover study aimed evaluate the safety and efficacy of home-based NMES as adjunct cardiac rehabilitation (CR) improving physical function in frail older adult with chronic heart failure (CHF).
This paper addresses accident detection where we not only detect objects with classes, but also recognize their characteristic properties. More specifically, aim at simultaneously detecting object class bounding boxes on roads and recognizing status such as safe, dangerous, or crashed. To achieve this goal, construct a new dataset propose baseline method for benchmarking the task of detection. We design an network, called Attention R-CNN, which consists two streams: one is classes property...
Model experiments at 10-GHz band have been performed to obtain optimum structures of printed resonant antennas for monolithic GaAs Schottky-diode detectors in the submillimeter-wave region. Design charts antenna structures, which are also useful a thin-film metal-to-metal diode structure on dielectric substrate, presented.
Visual SLAM systems targeting static scenes have been developed with satisfactory accuracy and robustness. Dynamic 3D object tracking has then become a significant capability in visual the requirement of under-standing dynamic surroundings various scenarios including autonomous driving, augmented virtual reality. However, performing solely monocular images remains challenging problem due to difficulty asso-ciating features estimating their positions. In this paper, we present MOTSLAM, system...
Amount and variety of training data drastically affect the performance CNNs. Thus, annotation methods are becoming more critical to collect efficiently. In this paper, we propose a simple yet efficient Interactive Self-Annotation framework cut down both time human labor cost for video object bounding box annotation. Our method is based on recurrent self-supervised learning consists two processes: automatic process interactive process, where aims build supported detector speed up process....
The prognosis of high-risk metastatic hormone-naïve prostate cancer is poor, and real-world evidence therapeutic options sequences lacking. J-ROCK study aimed to evaluate the outcomes in a setting Japan.Patients with diagnosed after May 2019 were eligible. Based on their treatment within 3 months diagnosis, patients allocated either cohort 1 (androgen deprivation therapy alone or combined androgen blockade bicalutamide) 2 abiraterone acetate+prednisolone, docetaxel, enzalutamide,...
A speech coding algorithm for application to the Japan digital cellular half-rate coder has been developed based on multiband excitation (MBE) using 3.0 kbit/s. The target performance is at same level as that of a full-rate operating 6.7 quantization scheme spectral envelope MBE parameters described. New features include an efficient dimension converter, interframe vectors, and multistage vector with interpolative quantization. simplified model voiced/unvoiced division method...
A generalised expression of the admittance diodes with arbitrary field-dependent injection is presented. Using this expression, negative conductance injection-limited Gunn diode offers a wideband performance.
During the nationwide state of emergency, many hospitals could not provide outpatient cardiac rehabilitation for disease patients in order to minimize coronavirus 2019 (COVID-19) incidence. The purpose this study was examine trajectories frailty, physical function and activity levels due interruption resumption by COVID-19 elderly heart failure patients. Fifteen who did attend during emergency but resumed it after were included. Frailty, assessed with Kihon checklist (KCL), various tests...

Aim The combination of dynapenia (age‐related muscle weakness) and obesity is referred to as dynapenic obesity. We examined the associations between cortical bone thickness trabecular density. Methods participants were 797 community‐dwelling postmenopausal women (with an average age 62.5 years) who stratified into normopenia without obesity, (dynapenia), with (obesity) (dynapenia obesity) groups based on their grip strength body fat percentage. Cortical density measured using ultrasonic...
Abstract The auto-resonant peniotron has been theoretically expected to have a very high conversion efficiency (nearly 100%) for an ideal electron beam with appropriate value the velocity ratio interacting in suitable circuit electromagnetic wave whose phase is equal of light free space.
