Secondary Mediastinal Bleeding Caused by Parathyroid Adenocarcinoma: A Case Report.

Introduction: The clinical picture of parathyroid tumors is mainly related to hypercalcemia such as kidney stones and bone and muscle pain. However, spontaneous cervical hemorrhage due to parathyroidoma bleeding is rare with clinical manifestations of the painful swelling and bruising of the neck accompanied by dysphagia and dyspnea.

Case Presentation: We report a case of a 71-year-old female patient who presented with acute cervical swelling and extensive bleeding spreading from the neck to the abdomen and 2 flanks.

Tracking Multiple Marine Ships via Multiple Sensors with Unknown Backgrounds.

In multitarget tracking, knowledge of the backgrounds plays a crucial role in the accuracy of the tracker. Clutter and detection probability are the two essential background parameters which are usually assumed to be known constants although they are, in fact, unknown and time varying. Incorrect values of these parameters lead to a degraded or biased performance of the tracking algorithms.

Tracking Multiple Targets from Multistatic Doppler Radar with Unknown Probability of Detection.

The measurements from multistatic radar systems are typically subjected to complicated data association, noise corruption, missed detection, and false alarms. Moreover, most of the current multistatic Doppler radar-based approaches in multitarget tracking are based on the assumption of known detection probability. This assumption can lead to biased or even complete corruption of estimation results.

On normalized MSE analysis of speech fundamental frequency in the cochlear implant-like spectrally reduced speech.

In this paper, we present a quantitative study on the speech fundamental frequency (F0) of the cochlear implant-like spectrally reduced speech (SRS). The SRS was synthesized from the subband amplitude and frequency modulations (AM and FM) of original clean speech utterances selected from the TI-digits database. The SRS synthesis algorithm was derived from the frequency amplitude modulation encoding (FAME) strategy, proposed by Nie et al.
