Although more than 90% of melanomas have cutaneous origins, melanomas sometimes present metastatically with no apparent primary lesion. A 62-year-old female presented with black pigmentation on her left thumbnail that had begun 2 years earlier and after the biopsy, she was diagnosed with malignant melanoma. Interestingly, 7 years earlier, a 4 cm palpable mass on her left axilla had been diagnos...

OBJECTIVE AND METHODS Inclusion body myositis is said to have both myopathic and neurogenic features on electrophysiological tests. Twenty one studies from 20 patients with biopsy defined inclusion body myosis, 13 of whom had quantitative electromyography (qEMG), were reviewed to determine if this technique added diagnostic specificity (one patient had both needle EMG and a later study with qEM...

Chemical communication is mediated by signal production and signal perception and in house mice (Mus musculus), both processes involve lipocalin proteins (OBP,MUP, LCN) that transport volatiles and protect them in tissues where they are produced. However, potential roles of lacrimal, nasal, and salivary lipocalins are still not well known. We aimed to determine the expression of the recently de...

The role of individual genetic heterozygosity in mate choice is the subject of much current debate. Several recent studies have reported female preference for more heterozygous males, but the mechanisms underlying heterozygote preference remain largely unknown. Females could favor males that are more successful in intrasexual competition, but they could also assess male heterozygosity directly ...

We use tools from geometric statistics to analyze the usual estimation procedure of a template shape. This applies to shapes from landmarks, curves, surfaces, images etc. We demonstrate the asymptotic bias of the template shape estimation using the stratified geometry of the shape space. We give a Taylor expansion of the bias with respect to a parameter σ describing the measurement error on the...

In orthogonal frequency division multiplexing (OFDM) systems, an integer part of a frequency offset (IFO) that causes ambiguity in data demodulation is estimated generally by comparing correlations between the received and local signals for IFO candidates. In this paper, we propose an IFO estimation scheme that provides a tradeoff between the estimation performance and the computational complex...

The paper considers the application of instantaneous harmonic analysis to a real-time vocal processing system for pitch, timbre and time-scale modifications. The analysis technique is based on narrow band filtering using special analysis filters with frequency-modulated impulse response. The main advantage of the technique is high accuracy of harmonic parameters estimation that provides adequat...

Statistics) Momentum Scale Estimation Using Maximum Likelihood Template Fitting by Yu Zeng Department of Statistics Duke University Date:

In this paper we address the problem of visual simultaneous localization and mapping (VSLAM) using a single camera as the sole sensor. A VSLAM system estimates its position and orientation (pose) by tracking distinct landmarks in the environment using its camera. Most approaches detect feature points in the environment, using an interest point operator that looks for small textured image templa...

Amplification by polymerase chain reaction is often used in the preparation of template DNA molecules for next-generation sequencing. Amplification increases the number of available molecules for sequencing but changes the representation of the template molecules in the amplified product and introduces random errors. Such changes in representation hinder applications requiring accurate quantifi...
