This leading edge passive L-Band instrument was acquired by NRL shortly before the campaign. Development of techniques for its use, and studies to understand its performance, are important parts of the acquisition process. In this paper we will examine instrument calibration and noise issues for STARRS which are associated with the flights conducted as part of the EuroSTARRS campaign, from November 16-23, 2001 in Germany, France and Spain. The issues we will address here are: pitch and roll improvements, L-Band absolute and ocean calibration, instrument stability, and environmental noise sources. A strong environmental noise source, located in the direction of Barcelona, was noticed during the Casablanca flight. A second environmental source was noted in the analysis later. The high altitude section of the Casablanca flight has elevated TB (most notably in all the outboard beams) relative to the low altitude section of the flight. The effects such environmental (presumably man-made) sources. Will have on satellite observations of L-Band brightness temperature may be significant.

For pharmacoepidemiological studies, structured classification of both morbidity and pharmaceuticals is required for meaningful analysis. The search for a suitable pharmaceutical classification proved fruitless. While the Australian Government has recently adopted the Anatomical Therapeutic Chemical (ATC) Classification as the national standard, this only classifies drugs to the generic level. None of the extended coding systems used in hospital pharmacies, by community pharmacists, or by Government are hierarchically structured. The extension code we have developed, is an analytical algorithm comprising independent fields for: dosage; strength; manufacturer and brand; and pack size. The codes within each field are also structured in a hierarchical manner. The result is an extension code of 21 digits, each digit or group of digits having a meaning. The structure of this classification will allow analysis of any aspect of the drug prescribed. This system is designed for computerised entry of text and transparent coding of the data-not for manual coding on paper nor manual code entry to the computer.

Low salinity water can transport natural and manmade river-borne contaminants into the sea, and can directly stress marine ecosystems that are adapted to higher salinity levels. An efficient method of mapping surface salinity distribution over large ocean areas is required to address such environmental issues. We describe here an investigation of the utility of airborne remote sensing of sea surface salinity using an L-band passive microwave radiometer. The study combined aircraft overflights of the scanning low frequency microwave radiometer (SLFMR) with shipboard and in situ instrument deployments to map surface and subsurface salinity distributions, respectively, in the Great Barrier Reef Lagoon. The goals of the investigation were (a) to assess the performance of the airborne salinity mapper; (b) to use the maps and in situ data to develop an integrated description of the structure and zone of influence of a river plume under prevailing monsoon weather conditions; and (c) to determine the extent to which the sea surface salinity distribution expressed the subsurface structure. The SLFMR was found to have sufficient precision (1 psu) and accuracy (f 3 psu) to provide a useful description of plumes emanating from estuaries of moderate discharge levels with a salinity range of 16 to 32 psu in the open sea. The aircraft surveys provided a means of rapidly assessing the spatial extent of the surface salinity distribution of the plume, while in situ data revealed subsurface structure detail and provided essential validation data for the SLFMR. The combined approach allowed us to efficiently determine the structure and zone of influence of the plume, and demonstrated the utility of sea surface salinity remote sensing for studying coastal circulation in tropical seas.

The 4,572 cases reported in 1988 represent a ninefold increase since 1982, when national surveillance was established, and a doubling of cases over the previous year (2,368 cases were reported in 1987). Lyme disease has spread from its original geographic focus in the northeast to include 43 states, with marked regional differences in incidence rates. New York state alone reported 56% of all the cases in 1988. Six northeastern states (New York, New jersey, Connecticut, Pemisylvania, Rhode Island, and Massachusetts) accounted for 80% of the nation's cases in 1987 and 1988. These states in addition to Wisconsin, Minnesota, and California, collectively account for 95% of cases reported in 1987-1988. A preliminary analysis indicates that cases in the Pacific states, primarily California, occur over a broader range of months and represent a different age distribution than cases in other regions. Differences in tick vector species, their rates of infection, and ecology may be reflected in regional differences in risk and epidemiologic patterns of Lyme disease.

The system is capable of performing wide area mapping at a rate of 100 km2/hr from low flying aircraft. Called the Scanning Low-Frequency Microwave Radiometer (SLFMR), the system is designed to operate from a small single engine aircraft. The system operates at 1.4 GHz, and utilizes a 64 element dipole antenna array to project up to 8 beams (6 usable) cross track to the direction of the flight path. This paper concerns the design and performance of the system

Her doctors say it is a miracle she has reached age six. Tami cannot talk or walk, and she needs ongoing physical therapy. Tami is bedridden and needs twenty-four-hour care. She lives at home, communicating through eye movements and interacting as an important member of her family. Tami's private insurance has been covering her home health care, but it has now reached its limits. Tami's family is looking to the Medicaid program to cover the care that Tami needs, but Medicaid says it will pay for only seven hours of home care each day. Daniel is fourteen years old. He suffers from emotional illness, including psychoses and depression. Prior to October 1999, he was cared for by in-home workers, funded through Medicaid. He was functioning well. However, the Medicaid agency cut back on his coverage. Daniel's condition deteriorated, and he was initially placed in a state psychiatric hospital. Subsequently, he has been bouncing between the hospital and residential group home settings-a scenario which will likely continue unless his Medicaid home-based care is reinstated. Chad is a thirty-two-year-old man with traumatic brain injury. With home health and personal care assistance, Chad can live in his own apartment. However, his condition demands consistency and a focus on social behavior. Unfortunately, the individuals who are providing services to Chad through the Medicaid program are untrained and have exhibited inappropriate behavior. On one occasion, Chad's mother was summoned to the apartment, only to find a nineteen-year-old care provider passed out on the sofa, naked from the waist down with beer cans strewn around him.

Such sensing methods can employ transducers small enough to fit into a robot gripper, thereby providing terminal homing capability. Any such short range time-of-flight systems, however, have to solve the problem of rapid receiver recovery after the transmit pulse. In the present case the problem has been solved by an active damping scheme. The transducer is a capacitive element and is connected across an inductor to form an electrically resonant circuit at the acoustic frequency of interest. The LC tank is in the feedback path of a novel circuit that can be changed continuously from positive to negative feedback conditions. When the feedback is positive oscillations rapidly build up, when negative they just as rapidly die down. At the end of each positive - negative cycle essentially all of both the electrical and mechanical energy has been extracted from the system, which is then ready to receive the echo. In this way ranging is readily achieved down to ∼1", which is adequate for robot gripper applications.

The endurance degradation associated with this erase mechanism is found to be different from those using the conventional source-side erase methods, as the better erase margin and worse program degradation are observed. The improvement of erase margin is then investigated by using

Passive microwave sensors are capable of measuring sea surface salinity, and recent advances in technology suggest that such measurements may soon be feasible on a global basis from Earth orbit. Aircraft-mounted instruments have been developed to validate the technology and address the problem of developing robust algorithms for remote sensing of sea surface salinity. Two aircraft instruments, the Scanning Low Frequency Microwave Radiometer (SLFMR) and the Electronically Scanned Thinned Array Radiometer (ESTAR), have successfully demonstrated remote sensing of salinity in the coastal ocean. Sensors for monitoring salinity from space that utilize the thinned array technology demonstrated by ESTAR have recently been proposed to the National Aeronautics and Space Administration and the European Space Agency.

The objective of this study was to quantify the effects of increasing initial population densities (Pi) of B. longicaudatus on cotton yield and root mass. In a field plot study, nematicide application and cropping history were used to obtain a wide range of Pi values. Cotton yields were regressed on Pi density of B. longicaudatus to quantify yield losses in the field. In controlled environmental chambers, cotton was grown in soil infested with increasing Pi's of B. longicaudatus. After 40 days, root systems were collected, scanned on a desktop scanner, and root lengths were measured. Root lengths were regressed on inoculation density of B. longicaudatus to quantify reductions in the root systems. In the field, high Pi's (>100 nematodes/130 cm(3) of soil) reduced yields to n...

Our purpose was to establish a new brain image database (BRAID) that allows the statistical correlation of brain functional measures with anatomic lesions revealed by clinical brain images. Data on 303 participants in the MR Feasibility Study of the Cardiovascular Health Study were tested for lesion/deficit correlations. Functional data were derived from a limited neurologic examination performed at the time of the MR examination. Image data included 3D lesion descriptions derived from the MR examinations by hand segmentation. MR images were normalized in-plane using local, linear Talairach normalization. A database was implemented to support spatial data structures and associated geometric and statistical operations. The database stored the segmented lesions, patient functional scores, and several anatomic atlases. Lesion-deficit association was sought by contingency testing (chi2...
