An unusual palatal mass in a 54-year-old male: report of a rare case

Rhinosporidiosis is a chronic, granulomatous, muco-cutaneous infection caused by Rhinosporidium seeberi. The infection is non-contagious and sporadic in humans, affecting predominantly the mucous membrane of the upper respiratory tract. It is quite an uncommon condition and seldom affects the oral mucosa. The clinical presentation of this condition in the oral cavity can mimic many other conditions. Here, we report a unique case of recurrent rhinosporidiosis affecting the palate in a 54-year-old male

On estimation of discriminant coefficients

Estimation of discriminant coefficients arises in linear discriminant analysis when the Fisher's linear discriminant function is viewed as the posterior log-odds. Accordingly, we treat the problem of estimating the discriminant coefficients under the quadratic loss. We obtain a class of improved estimators dominating the 'unbiased' estimator, considerably generalizing earlier work of Haff (1986).Wishart identity precision matrix unbiased estimator

Dactoscopy in human identification: A retrospective study in Bhubaneswar City

Anthropometry, fingerprints, age estimation, gender determination, blood types, DNA, and dental features are examples of traditional techniques for identifying a person. The present study aimed toward observing the patterns of fingerprints and their reliability toward human identification. A retrospective study was conducted in a tertiary care unit in Bhubaneswar city. Fingerprints were recorded, and the individual identification mark was noted for each individual. Reporting of the patterns was done. Sir Henry Galton's classification was used to study the fingerprint patterns. IBM Statistical Package for Social Sciences was used for the statistical analysis. Type A was the most common type seen for the right-hand little finger. Type A was the most common type seen for the left-hand little finger; Type C was the most common type seen for the left-hand ring finger. Statistically significant correlations between gender and dermatoglyphics were found, supporting their usage as trustworthy forensic evidence

Measurement of the radius of Mercury by radio occultation during the MESSENGER flybys

The MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft completed three flybys of Mercury in 2008–2009. During the first and third of those flybys, MESSENGER passed behind the planet from the perspective of Earth, occulting the radio-frequency (RF) transmissions. The occultation start and end times, recovered with 0.1 s accuracy or better by fitting edge-diffraction patterns to the RF power history, are used to estimate Mercury's radius at the tangent point of the RF path. To relate the measured radius to the planet shape, we evaluate local topography using images to identify the high-elevation feature that defines the RF path or using altimeter data to quantify surface roughness. Radius measurements are accurate to 150 m, and uncertainty in the average radius of the surrounding terrain, after adjustments are made from the local high at the tangent point of the RF path, is 350 m. The results are consistent with Mercury's equatorial shape as inferred from observations by the Mercury Laser Altimeter and ground-based radar. The three independent estimates of radius from occultation events collectively yield a mean radius for Mercury of 2439.2±0.5 km
