Initial presentation of acute myelogenous leukemia in the infiltrate underlying an actinic keratosis
We report an 85-year-old female patient who presented with an erythematous keratotic lesion on her temple suspicious of squamous cell carcinoma. Histological evaluation revealed actinic keratosis, but the underlying atypical infiltrate contained atypical myeloid forms consistent with acute myelogenous leukemia (AML). Upon further questioning, it was determined that the patient had a history of myelodysplastic syndrome. Her skin biopsy provided the first evidence of progression to AML. This case serves as an important reminder of the role the dermatopathologist plays in identifying serious systemic disease

Creation of a Sport Backstop Using Axiomatic Design
The objective of this project was to design and physically develop an affordable, meaning under $500 retail price, device that can accurately provide feedback on speed and position of a pitch. Current products like this are usually either expensive, inaccurate or both. Additionally, they often lack feedback on position of the pitch over homeplate. Due to these limitations, customers are often dissatisfied with the smart backstop product they have purchased. Axiomatic Design theory and concept-knowledge theory were used in the design of a new smart backstop product. Our team has come to a solution that can provide more accurate results for speed and position of a pitch and provide feedback in a clear and user-friendly manner
Use of autonomous profiling floats for validation and calibration of satellite ocean color estimates
The LITE Correlative Measurements Campaign in Southern Italy: Preliminary Results
Abstract. In conjunction with the LITE mission an intensive
LIDAR measurement campaign was carried out in Napoli
(40 50 0 N -14 10 0 E, at sea level) and Potenza (40 36 0 N - 15 44 0 E,820 m a.s.l.). The LITE experiment, flying on board
the Space Shuttle in the period September 10–19, 1994,
represents the first attempt to perform global coverage LI-
DAR measurements from space. The LITE experiment was
planned to provide measurements of clouds, tropospheric and
stratospheric aerosols, stratospheric temperature and density,
characteristics of the planetary boundary level as well as surface
albedo. Because of the relative distance between LITE
ground tracks and the two southern Italy validation stations
for all passes, measurements carried out in Napoli and Potenza
were primarily aimed at validation of LITE stratospheric
measurements. In the present preliminary analysis Potenza LI-
DAR measurements in coincidence with the orbit 128 LITE
overpass, are reported and discussed. Potenza LIDAR data
show a good agreement with LITE data in terms of aerosol
scattering ratio both at 355 nm and 532 nm (R A,355 and R A,532 );
the two data sets appearing to be highly correlated. LITE
vs. Potenza LIDAR measurements of R A,355 and R A,532 display
a correlation coefficient of 0.72 and 0.86, respectively.
Stratospheric aerosol dimensional characteristics are determined

The SuperB muon detector, status and perspectives
The superB project foresees the construction of a high intensity super-flavor factory at the Cabibbo Lab, in Tor Vergata (near Rome). The experiment, based on a high intensity asymmetric electron-positron collider, and on the related detector, is expected to reach a very high luminosity: 2 × 1036cm-2s-1, that will allow the high statistic study of rare decays and, possibly, will show evidences of new physics. © 2012 IEEE

Splash and Re-entrant albedo fluxes measured in the PAMELA experiment
AbstractThis work devoted to the description of the method for splash albedo protons identification in the satellite-born experiment PAMELA. In contrast to the reentrant albedo particles, which enter into the main aperture of the instrument, the direct albedo particles enter from the opposite direction, so they pass a few detectors, including calorimeter, before being register by the magnetic spectrometer. The developed method take into account the influence of these detectors on the selection of events and measurements of their characteristics. To test this method the energy spectrum of reentrant albedo protons in various regions of the near-Earth space reconstructed; it is in a good agreement with the classical measurements in the main aperture. Therefore, this method can be useful to obtain a new physical data about fluxes of splash albedo protons in the PAMELA experiment, which, unlike the reentrant albedo, can be study even at high geomagnetic latitudes
