  This article contains a proof of the existence of SBR measures for the family of maps of the plane known as Lozi maps: L(x, y) = (1-a׀x׀+y, bx). We also prove that the number of SBR measures is finite. Our approach also yields invariant measures for other classes of dynamical systems like piecewise expanding mappings of an interval with infinitely many pieces and Holder derivative. Although known to specialists from my 1983 dissertation (University of California, Berkeley), the results presented in this article have never been published. I am delighted that the article found its place in the current volume, as the ideas of several papers that Jim Yorke co-authored or inspired played an important role in my approach.

  In this paper we focus on three major task: 1) discussing our methods: Our method captures a portion of the data in DCD flowsheets, kidney perfusion data, and Flowsheet data captured peri-organ recovery surgery. 2) demonstrating the result: We built a comprehensive, analyzable database from 2022 OPTN data. This dataset is by far larger than any previously available even in this preliminary phase; and 3) proving that our methods can be extended to all the past OPTN data and future data. The scope of our study is all Organ Procurement and Transplantation Network (OPTN) data of the USA organ donors since 2008. The data was not analyzable in a large scale in the past because it was captured in PDF documents known as ``Attachments'', whereby every donor's information was recorded into dozens of PDF documents in heterogeneous formats. To make the data analyzable, one needs to convert the content inside these PDFs to an analyzable data format, such as a standard SQL database. In this paper we will focus on 2022 OPTN data, which consists of $\approx 400,000$ PDF documents spanning millions of pages. The entire OPTN data covers 15 years (2008--20022). This paper assumes that readers are familiar with the content of the OPTN data. [Journal_ref: ]
