Doped piezoceramic lead zircanate titanate has been characterized in the frequency range of 20–60 MHz using ultrasonic spectroscopy. Theoretical analyses were performed for the reflection and refraction of acoustic waves at the interface of water-piezoelectric ceramic. The incident directions of the wave were chosen to be appropriate for ultrasonic spectroscopy measurements. Shear wave spectrum...

The nationwide strong-motion seismograph network of K-NET and KiK-net in Japan successfully recorded the strong ground motions of the 2016 Kumamoto earthquake sequence, which show the several notable characteristics. For the first large earthquake with a JMA magnitude of 6.5 (21:26, April 14, 2016, JST), the large strong motions are concentrated near the epicenter and the strong-motion attenuat...

under the contemporary scenario of global climate change and increasing coastal eutrophication, baseline studies of phytoplankton diversity and distribution in relation to habitat conditions constitute the first approach to evaluate potential shifts at the base of the food webs. here we present data of phytoplankton species composition and environmental variables in winter 2006 in a temperate ...

Competing hypotheses for explaining the role of anxiety in the relation between attention-deficit/hyperactivity disorder (ADHD) symptoms and childhood aggression were evaluated. Two studies tested whether anxiety exacerbated, attenuated, or had no effect on the relation between ADHD and aggression subtypes among psychiatrically hospitalized children. In Study 1 (N = 99), children who scored abo...

background: in this study, quantitative 32p bremsstrahlung planar and spect imaging and consequent dose assessment were carried out as a comprehensive phantom study to define an appropriate method for accurate dosimetry in clinical practice. materials and methods: ct, planar and spect bremsstrahlung images of jaszczak phantom containing a known activity of 32p were acquired. in addition, phanto...

BACKGROUND Cancer cachexia and skeletal muscle wasting are related to poor survival. In this study, quantitative body composition measurements using computed tomography (CT) were investigated in relation to survival, post-operative complications, and surgical site infections in surgical patients with cancer of the head of the pancreas. METHODS A prospective cohort of 199 patients with cancer ...

Abstract In general linear modeling (GLM), eta squared ( ? 2 ) is the dominant statistic for explaining power of an independent variable. This article discusses a less-studied deficiency in : its values are seriously deflated, because estimates by coefficient deflated. Numerical examples show that deflation may be as high 0.50–0.60 units correlation and 0.70–0.80 power. A simple mechanism to ev...

Multiwavelength images from the far-UV (?0.15 ?m) to submillimeter of central region galaxy NGC 3351 are analyzed constrain its stellar populations and dust attenuation. Despite hosting a ?1 kpc circumnuclear starburst ring, deviates IRX–? relation, relation between infrared-to-UV luminosity ratio UV continuum slope ? that other galaxies follow. To understand reason for deviation, we leverage h...
