Comparative study of lidars for measuring atmospheric temperature and wind.

The uncertainty of lidar measured atmospheric temperature or line-of-sight (LOS) wind is inversely proportional to the signal-to-noise ratio (SNR) of the received photocounts. We term the proportionality constant, which depicts the efficacy of the measurement method, the single-photon (or unity SNR) measurement uncertainty for and/or measurement. In this study, we use the single-photon measurement uncertainty as the figure of merit to compare and understand the practical differences between Cabannes scattering (CS), Rayleigh inversion (RI), rotational Raman (RR), and laser induced fluorescence (LIF) lidars for atmospheric temperature and wind measurements, and to optimize the choice and receiver design of a lidar system for a potential application.

Injectable autologous chondrocyte implantation in acetabular cartilage defects: 2-year minimum clinical and MRI results.

Introduction: Early results using injectable autologous chondrocyte implantation (ACI) for the treatment of full thickness acetabular cartilage defects have been promising. However, so far there is no information on radiological results after injectable ACI using spheroids. The purpose of this sturdy was to (1) investigate the quality of tissue repair on MRI and (2) investigate the correlation between the MRI results and clinical results at a minimum follow-up of 24 months after third generation ACI in full thickness acetabular cartilage defects.

Atomic vapor filter revisited: a Cabannes scattering temperature/wind lidar at 770 nm.

Using an atomic/molecular vapor as an aerosol blocking filter for atmospheric temperature measurements with a Cabannes lidar is revisited. Different problems in previously used barium and iodine filters prevented them from delivering the 78 times signal advantage (8.8 times less uncertainty) over rotational Raman lidar.

Correlation of the Subjective Hip Value with Validated Patient-Reported Outcome Measurements for the Hip.

Background: The subjective hip value (SHV) was developed as a patient-reported outcome measurement (PROM) that is easily and quickly performed and interpreted. The SHV is defined as a patient's subjective hip measurement tool expressed as a percentage of an entirely normal hip joint, which would score 100%. The hypothesis is that results of the subjective hip value correlate with the results of the modified Harris hip score and the International Hip Outcome Tool in patients with hip-related diseases.

Injectable autologous chondrocyte implantation (ACI) in acetabular cartilage defects-three-year results.

To evaluate the clinical outcome after arthroscopic matrix-associated injectable autologous chondrocyte implantation (ACI) in patients with large full-thickness acetabular cartilage defects. ACI was performed in young patients with full-thickness acetabular cartilage defects ≥2 cm in a two-step arthroscopic procedure. The patients were followed closely with clinical examinations and pre- and postoperative scores.

Is the evaluation of the anterior inferior iliac spine (AIIS) in the AP pelvis possible? Analysis of conventional X-rays and 3D-CT reconstructions.

Introduction: A hypertrophic AIIS has been identified as a cause for extraarticular hip impingement and is classified according to Hetsroni using 3D-CT reconstructions. The role of the conventional AP pelvis X-ray, which is the first standard imaging step for the evaluation of hip pain, has not been investigated yet.

Materials And Methods: AP pelvis X-rays and 3D-CT reconstructions of patients were evaluated regarding their morphology of the AIIS.

Injectable autologous chondrocyte transplantation for full thickness acetabular cartilage defects: early clinical results.

Introduction: Acetabular cartilage lesions are frequently seen in young patients with hip pain and have been identified as an important prognostic factor. New therapies have complemented abrasion and microfracture procedures.

Retrieving mesopause temperature and line-of-sight wind from full-diurnal-cycle Na lidar observations.

Narrowband Na lidar measurement of mesopause region temperatures were pioneered by Fricke and von Zahn in 1985, in 1990 by She et al. at Colorado State University (CSU), with upgrades to measure both temperature and wind in 1994, and under sunlit conditions in 1996 with 24 h continuous observational capability in 2002. This paper details the assumptions and procedures for the retrieval of mesopause region temperatures, line-of-sight winds, and sodium densities from day and night signals from the CSU narrowband Na lidar.

ACO model should encourage efficient care delivery.

The independent Office of the Actuary for CMS certified that the Pioneer ACO model has met the stringent criteria for expansion to a larger population. Significant savings have accrued and quality targets have been met, so the program as a whole appears to be working. Ironically, 13 of the initial 32 enrollees have left.

Cylindrical acoustical holography applied to full-scale jet noise.

Near-field acoustical holography methods are used to predict sound radiation from an engine installed on a high-performance military fighter aircraft. Cylindrical holography techniques are an efficient approach to measure the large and complex sound fields produced by full-scale jets. It is shown that a ground-based, one-dimensional array of microphones can be used in conjunction with a cylindrical wave function field representation to provide a holographic reconstruction of the radiated sound field at low frequencies.

Wind-bias correction method for narrowband sodium Doppler lidars using iodine absorption spectroscopy.

We present a technique to measure the frequency chirp introduced by the laser pulse amplification process in the transmitter of the Colorado State University sodium lidar system. This chirp causes a systematic radial wind bias that must be removed from the reported wind measurements. An iodine absorption line located near the lidar operating wavelength of 589.

Encephalitis in aborted bovine fetuses associated with Bovine herpesvirus 1 infection.

Brain tissue from 12 aborted bovine fetuses submitted to the Wisconsin Veterinary Diagnostic Laboratory revealed histologic lesions that consisted of glial nodules and variable degrees of mononuclear inflammation, microhemorrhage, neuronal necrosis, and cerebral cortical cavitation. A diagnosis of Bovine herpesvirus 1 (BHV-1) abortion had been made in all of these cases through multiple testing modalities. Brain tissue from 8 of the 12 fetuses was immunohistochemically stained with a monoclonal antibody specific to BHV-1, and, in 5 fetuses, there was positive intralesional staining of neurons, glial cells, and endothelial cells.
