An Investigation of the Structural Qualities of Certain Technical Elements in a Series of Oil Paintings Related to the Figure
The purpose of this study is (1) to investigate structural qualities of certain technical elements of oil painting, (2) to apply these qualities and means to a series of oil paintings related to the figure, (3) to evaluate the quality of structure achieved by these means, and (4) to arrive at conclusions and suggestions for future modifications of the candidate\u27s paintings techniques
A Human Paradox: The Nazi Legacy of Pernkopf’s Atlas
Eduard Pernkopf’s Atlas of Topographical and Applied Human Anatomy is a four-volume anatomical atlas published between 1937 and 1963, and it is generally believed to be the most comprehensive, detailed, and accurate anatomy textbook ever created. However, a 1997 investigation into “Pernkopf’s Atlas,” raised troubling questions regarding the author’s connection to the Nazi regime and the still unresolved issue of whether its illustrations relied on Jewish or other political prisoners, including those executed in Nazi concentration camps. Following this investigation, the book was removed from both anatomy classrooms and library bookshelves. A debate has ensued over the book’s continued use, and justification for its use has focused on two issues: (1) there is no definitive proof the book includes illustrations of concentration camp prisoners or Jewish individuals in particular, and (2) there is no contemporary equivalent to this text. However, both points fail to address the central importance of the book, not simply as part of anatomy instruction, but also as a comprehensive historical narrative with important ethical implications. Having encountered a first edition copy, these authors were given a unique opportunity to engage with the text through the respective humanities lenses of history, ethics, and narrative. In doing so, an instructive and profound irony has surfaced: Nazis, including Pernkopf, viewed specific groups of people as less than human, giving rise to unthinkable atrocities perpetuated against them. However, these same individuals became the sources for the creation of the Atlas, which served as the model for primary instruction on the human form for more than half of the twentieth century. In this article, we recount the difficult and somewhat opaque provenance of this book, engage the ethical questions surrounding both its creation and its use, and ultimately propose a pedagogical methodology for its continued use in medical education

Generation of Mid-IR Wavelengths
Generation of mid-IR wavelengths

Abstract
Research to determine basic molecular properties utilizing pump/probe experiments is an on going effort at SLAC. Here we have been given the task to generate mid-IR laser pulses and commission a mid-IR detector for said experiments and research. The mid-IR pulses will be used to probe the changes in molecular properties induced by exciting the electrons in molecules with visible pump pulses. In order to accomplish this, an optical parametric amplifier (OPA) has been set-up and aligned. The pump beam for the OPA is a 40 femtosecond 800nm beam from a Ti:Sapphire chirped pulse amplified laser system with an output of approximately 1mJ/pulse. In the OPA, one photon of higher energy is frequency mixed or split into two photons of lower energy using nonlinear processes in a nonlinear crystal. Here we have generated 1400nm and 1900nm wavelengths in the near-IR spectrum out of the OPA from the 800nm pump. These signal and idler output wavelengths from the OPA will then be frequency difference mixed in a second nonlinear crystal to yield mid-IR wavelengths to test the mid-IR detector
Liver Allocation to Non-Citizen Non-Residents: An Ethical Framework for a Last-In-Line Approach
The incidence of non-U.S. citizen non-U.S. resident patients coming to the United States specifically for deceased donor liver transplantation raises compelling ethical questions that require careful consideration. The inclusion of these often financially and/or socially privileged patients in the pool of potential candidates for an absolutely scarce and life-saving liver transplant may exacerbate disparities already existing in deceased donor liver allocation. In addition, their inclusion on organ transplant waiting lists conflicts with recognized ethical principles of justice and reciprocity. Moreover, preliminary data suggest that public awareness of this practice could discourage organ donation, thereby worsening an already profound supply–demand gulf. Finally, U.S. organ allocation policies and statutes are out of step with recently promulgated international transplant guidelines, which prioritize self-sufficiency of organ programs. This article analyzes each of these ethical conflicts within the context of deceased donor liver transplantation and recommends policy changes that align the United States with international practices that discourage this scenario
