To demonstrate and test the validity of a novel deep-learning-based system for the automated detection of pulmonary nodules. Materials and Methods: The proposed system uses 2 3D deep learning models, 1 for each of the essential tasks of computer-aided nodule detection: candidate generation and false positive reduction.

The evaluation of postoperative total knee arthroplasty (TKA) alignment mainly relies on measurement data obtained from plain radiographs. The aim of this retrospective observational study was to document the intra- and inter-observer reliability in assessment of TKA component positioning after surgery using a three-dimensional (3D) computed tomography (CT) image matching system.

Magnetic motion capture systems require the real actor to wear a set of sensors, which are capable of measuring their spatial relationship to a centrally located magnetic transmitter. The position and orientation of each sensor is then used to drive an animated character. One problem is the need for synchronizing receivers. The data stream from the receivers to a host computer consists of 3D positions and orientations for each receiver.

Optical motion capture systems are based on small reflective sensors called markers attached to an actor's body and on several cameras focused on performance space. By tracking positions of markers, one can get locations for corresponding key points in the animated model, e.g. we attach markers at joints of a person and record the position of markers from several different directions. We then reconstruct the 3D position of each key point at each time. The main advantage of this method is freedom of movement; it does not require any cabling....

An investor who has sold stock short in anticipation of a price decline can limit a possible loss by purchasing call options. Remember that shorting stock requires a margin account and margin calls may force you to liquidate your position prematurely. Although a call option may be used to offset a short stock position's upside risk, it does not protect the option holder against additional margin calls or premature liquidation of the short stock position. Assume you sold short 100 shares of XYZ stock at $40 per share.

One finds that there is a positive correlation between a country’s level of development and insurance coverage. Developed countries tend to have better developed and well- functioning insurance services sectors both domestically and in terms of insurance exports, as compared to developing countries. This is perhaps most evident when one compares the share of industrialized countries in the world insurance markets, which in 2004 stood at 88.5 per cent as compared with 11.4 per cent for emerging markets, the majority of which are developing countries.

The second group was formed of men with a suspicion of prostate cancer based on an elevated serum PSA and/or abnormal digital rectal examination, and the blood sample taken immediately before the prostate biopsy. The presence or absence of CPCs was to be compared with the biopsy results, the Gleason score, percent of sample infiltrated with cancer, and number of positive cores. The sensitivity, specificity, positive and negative predictive values were to be calculated. In men with a false negative test the details of the cancer detected would be evaluated.
