Aerosol particle shape is a key parameter affecting its physical characters, especially scattering properties[1]. The information of shape reveals important application in such fields as atmospheric radiation and remote sensing, climate research, radar meteorology[2]. The convenient availability and simplicity of the Lorenz-Mie theory has resulted in a widespread practice of treating non-spheri...

Imaging flow velocity measurements are essential for the investigation of unsteady complex flow phenomena, e.g., in turbomachines, injectors and combustors. The direct optical measurement on fluid molecules is possible with laser Rayleigh scattering and the Doppler effect. However, the small scattering cross-section results in a low signal to noise ratio, which hinders time-resolved measurement...

The number of suicides in Japan has increased to over 30,000 per year since 1998. Similarly, the number of suicides has been increasing in Mie Prefecture. In the present study, we examined the incidence and the circumstances of all suicidal cases that were reported to the Mie Prefectural Police Headquarters during the thirteen-year period 1990-2002. In Mie Prefecture, the number of suicides per...

Electromagnetic materials with tunable permeability and permittivity are highly desirable for wireless communication and radar technology. However, the tunability of electromagnetic parameters is an immense challenge for conventional materials and metamaterials. Here, we demonstrate a magnetically tunable Mie resonance-based dielectric metamaterials. The magnetically tunable property is derived...

Morphology-dependent resonances (MDR’s) of polystyrene microspheres were excited by an optical fiber coupler. For optical elimination of the air–cladding interface at the optical fiber coupler surface, the microsphere was immersed in an index-matching oil. MDR’s were observed, even though the relative refractive index between the microsphere and the oil was only 1.09. The observed MDR spectra a...

This paper describes how coherent backscattering is altered by an external magnetic field. In the theory presented, magneto-optical effects occur inside Mie scatterers embedded in a nonmagnetic medium. Unlike previous theories based on pointlike scatterers, the decrease of coherent backscattering is obtained in a leading order of the magnetic field using rigorous Mie theory. This decrease is st...

We present the mapping of the full plasmonic mode spectrum for single and aggregated gold nanoparticles linked through DNA strands to a silicon nitride substrate. A comprehensive analysis of the electron energy loss spectroscopy images maps was performed on nanoparticles standing alone, dimers, and clusters of nanoparticles. The experimental results were confirmed by numerical calculations usin...

Abstract Background Increasing evidence shows substantial variation in surgical performance measured by a (video-based) competency assessment tool (CAT). Moreover, suboptimal has been associated with less favorable patient outcomes complex minimal invasive procedures. It is likely this also applies for minimally esophagectomy (MIE). In previous study CAT MIE (MIE-CAT) was developed and validate...
