A Radar Echo Simulator for the Synthesis of Randomized Training Data Sets in the Context of AI-Based Applications.

Supervised machine learning algorithms usually require huge labeled data sets to produce sufficiently good results. For many applications, these data sets are still not available today, and the reasons for this can be manifold. As a solution, the missing training data can be generated by fast simulators.

Once in the Door, Grit May Matter More: An Evaluation of Grit in Medical Students.

Introduction: Health professions educators seek understanding of the process of learner performance and achievement. Grit, defined as passion and perseverance for long-term goals, has been implicated in this process. Research suggests that effort counts twice in achievement: skill times effort equals skill and, subsequently, skill times effort equals achievement.

An international practitioner data bank as a quality tool.

While international tort costs have not reached the level of those in the United States, international medical employers, like their American counterparts, must be able to ascertain updated objective information regarding the physicians they are going to employ, in order to protect their patients and organizations from the increasing risks in today's medical environment. The NPDB set up in the United States by the United States Congress provides a structure that can record and set standards for professional reviews. While the data bank established in the United States can still be considered a new entity, and the exact impact it has on quality, peer review and risk management is still being judged, it is the first step towards an organized, objective governing body.

Cost containment: the Middle East. Israel.

The Israeli Health Service was established with the intent of providing an equal standard of care to the entire Israeli population. The Health Service has dealt with changes over the years, including the governing of large populations of Judea, Samaria, and Gaza. In 1990, mass immigration brought 500,000 more individuals to Israel, putting an additional burden on medical services.

Human immunodeficiency virus infection among homeless men in a New York City shelter. Association with Mycobacterium tuberculosis infection.

The human immunodeficiency virus (HIV) seroprevalence among a selected sample of 169 high-risk homeless men residing in a congregate shelter in New York City, NY, was 62%. Seropositivity for HIV correlated significantly with intravenous drug use (odds ratio, 3.3; 95% confidence interval, 1.

Donor ambivalence: a key issue in families of children with end-stage renal disease.

This paper is based on the writers' clinical experience with children and adolescents who receive kidney transplants and members of their families who are involved in the process of identifying the best donor match. Specific concerns of the patients and their significant others are described, and two cases are used as illustrations. The role of ambivalence in donor selection is investigated and selected intervention sites are suggested.
