A laser cavity formed from a single defect in a two-dimensional photonic crystal is demonstrated. The optical microcavity consists of a half wavelength-thick waveguide for vertical confinement and a two-dimensional photonic crystal mirror for lateral localization. A defect in the photonic crystal is introduced to trap photons inside a volume of 2.5 cubic half-wavelengths, approximately 0.03 cub...

Purpose To describe the case of a patient developing corneal ectasia following LASIK for the correction of myopic astigmatism. Materials and Methods A 39-year-old man underwent bilateral uneventful LASIK for myopic astigmatism of -10.25 -1.75 ×040 OD and -8.00 -2.50 ×005 OS. Preoperative corneal pachymetry was 542 micrometers OD and 543 micrometers OS. Preoperative corneal topography showed b...

We have developed temperature-pulse microscopy in which the temperature of a microscopic sample is raised reversibly in a square-wave fashion with rise and fall times of several ms, and locally in a region of approximately 10 micrometers in diameter with a temperature gradient up to 2 degrees C/micrometers. Temperature distribution was imaged pixel by pixel by image processing of the fluorescen...

Anthropogenically induced climate change is of great current interest because of increases in atmospheric loading of infrared active (greenhouse) gases over the past 150 years and the inferred resultant increase in the flux of infrared radiation in the troposphere. In parallel with the increase in greenhouse gas loadings there has been an increase in loadings of tropospheric aerosols derived fr...

In many insects, sperm cells are produced in bundles with their heads being held together by a glycoprotein matrix secreted by a cyst cell. Mature sperm cells in the seminal vesicles are usually free, but in sawflies and several other insects, such structures (spermatodesmata) remain intact and sperm cells may be ejaculated as bundles. Here we report the occurrence of spermatodesmata in mature ...

Microspheres approximately 25 or 50 micrometers in diameter were systemically embolized from the left ventricular cavity. The number of microspheres given was empirically chosen to minimize the possibility of more than one microsphere lodging in an arteriole (3 mg/kg), yet was sufficient to allow for adequate histological assessment. The dogs were sacrificed after 24 hours, and focal areas of m...

X-ray luminescence computed tomography (XLCT) is a hybrid imaging modality with the potential to achieve a spatial resolution up to several hundred micrometers for targets embedded in turbid media with a depth larger than several millimeters. In this paper, we report a high spatial resolution XLCT imaging system with a collimated superfine x-ray beam in imaging the deeply embedded targets. A co...

La Biblioteca Digital de la Universidad de Castilla-La Mancha pretende ser ofrecer todas las posibilidades de una biblioteca tradicional, tanto en cuanto a recursos como a servicios, y no quedarse en una mera colección de textos accesibles pero desorganizados. Se presenta esta biblioteca desde su gestación hasta el momento actual mostrando las posibilidades que ofrece y la experiencia de su pue...
