Skyrmions coupled with the electromagnetic field via the gauged Wess-Zumino term

In soliton models expressed in terms of the non-linear chiral field, the electric current has an anomalous gauge-field contribution as the baryon current does. We study the spin polarized Skyrmions coupled with the electromagnetic field via the gauged Wess-Zumino term and calculate configurations of the Skyrmion and the gauge field with boundary conditions to ensure the physical charge number for baryons. Although the electromagnetic field via the gauged Wess-Zumino term affects physical quantities in small amounts, we find that the magnetic field forms a dipole structure owing to a circular electric current around the spin quantization axis of the soliton. This is understood on an analogy with the Meissner effect in the super conductor.The electric charge distributions turn out to have characteristic structures depending on the total charge, which suggests the intrinsic deformation of baryons due to orbital motions of the constituents.Comment: 8 pages, 5 figure

Images of nurses by senior high school students wishing to go on to the nursing course

本研究では、看護課程志望の高校生が看護職に対してどのようなイメージを持っているのか、看護教育機関の希望や将来の看護職種の希望は看護職に対するイメージと関係があるのかを明らかにしたいと考えた。岡山県下の全ての高校に在学中の看護課程志望高校生に対して、質問紙調査をおこなった。222名から回答が得られ、分析を行った結果、以下のことが明らかになった。1）看護課程志望高校生は看護職に対して非常に良いイメージを持っており、同時に労働条件の厳しさも理解していた。その良いイメージとは、看護職の持つ尊さや献身性に由来する自負心と、資格のもつ現実的利点であった。しかし、看護職の専門性を表す、高度な知識・判断・技術、生涯教育の必要性の認識は低かった。2）短大・大学を志望する高校生は、看護学校・准看護学校志望者に比べ、看護職は生涯教育を必要とするとイメージしていた。3）看護婦、保健婦、助産婦のどの職種を希望するかによって、看護職に対するイメージに違いがあった。A qusetionnaire survey was done by senior high school students wishing to go on to the nursing course in Okayama Prefecture, to know what images of nurses they had, what course for nursing education they wished to best for and what they would like nursing profession to be. Results of analysing data obtained from 222 students were as follows; 1. They had favorable images of nurses in high rates, although they also recognized the harsh working conditions. Those images were thought to be derived from the preciousness of nursing, devotion to people, and advantage of the license. But recognition of specialty of nursing indicated by items such as knowledge, judgement, skill and continuing education was low. 2. Necessity of continuing education was recognized by students wishing to go on to university or junior college better than students of vocational school of registered and assistant nurses. 3. Images of nurses were different by their choice of profession such as clinical nurses, public health nurses and midwives which they would like to be in the future

Illumination-Based Synchronization of High-Speed Vision Sensors

To acquire images of dynamic scenes from multiple points of view simultaneously, the acquisition time of vision sensors should be synchronized. This paper describes an illumination-based synchronization method derived from the phase-locked loop (PLL) algorithm. Incident light to a vision sensor from an intensity-modulated illumination source serves as the reference signal for synchronization. Analog and digital computation within the vision sensor forms a PLL to regulate the output signal, which corresponds to the vision frame timing, to be synchronized with the reference. Simulated and experimental results show that a 1,000 Hz frame rate vision sensor was successfully synchronized with 32 μs jitters

Effect of lattice distortions on the electron and thermal transport properties of transparent oxide semiconductor Ba1-xSrxSnO3 solid solution films

La-doped ASnO3 (A = Ba, Sr) have great potential as advanced transparent oxide semiconductors due to their large optical bandgap and relatively high electron mobility. The bandgap of Ba1-xSrxSnO3 solid solution increases from 3.2 eV (BaSnO3) to 4.6 eV (SrSnO3) with x. However, the increase in the bandgap is accompanied by reductions in the electrical conductivity. The versatility in the changes in the electrical properties are not trivial, and the property optimization has been challenging. Here we propose a simple metric for quantifying the transport properties of ASnO3. We investigated the electron/thermal transport properties of Ba1-xSrxSnO3 solid solution films and their relationship with the lattice distortion. The results suggest that the all transport properties of Ba1-xSrxSnO3 are dominated by the lattice distortion. This phenomenon is attributed to the distortions in the SnO6 octahedron, which consists the conduction band

Fabrication of GaAs MISFET with nm-thin oxidized layer formed by UV and ozone process

金沢大学工学部A gate insulating layer with single nm-order thickness for suppressing gate leakage current is one of the key factors in extending downsizing limits, based upon the scaling rule, of field-effect-type transistors. We describe the fabrication and characterization of GaAs MISFETs with a nm-thin oxidized layer as the gate insulating layer, which is formed by an ultraviolet (UV) and ozone process. The UV and ozone process forms oxidized GaAs layers near the surface, which effectively suppress the reverse leakage current by several orders of magnitude. The fabricated GaAs MISFET can operate not only in the depletion mode, but also in the accumulation mode up to 3 V gate voltage for 8-nm-thick oxidized layers due to the current blocking effect of the oxidized layer. A current cutoff frequency of 6 GHz and a maximum oscillation frequency of 8 GHz are obtained for a GaAs MISFET with 1-/spl mu/m gate length and 8-nm-thick oxidized layers
