Implementing a Novel "Frontiers in Neoplasia" Curriculum to Engage Fourth-Year Medical Students in Evidence-Based, Multidisciplinary Oncology Care.

Few medical students are exposed to evidence-based, multidisciplinary oncology care, and few studies in oncology education reflect consolidated pre-clinical curricula. We developed a four-week curriculum, "Frontiers in Neoplasia," for fourth-year medical students, which included didactic lectures, interactive site visits, and team-based simulations of tumor boards and clinical trial design. A mixed methods approach was utilized to investigate the course's impact on students' understanding and interest in oncology, involving pre- and post-course responses to Likert-scale and open-ended questions.

THz Polarimetric Imaging of Carbon Fiber-Reinforced Composites Using the Portable Handled Spectral Reflection (PHASR) Scanner.

Recent advancements in novel fiber-coupled and portable terahertz (THz) spectroscopic imaging technology have accelerated applications in nondestructive testing (NDT). Although the polarization information of THz waves can play a critical role in material characterization, there are few demonstrations of polarization-resolved THz imaging as an NDT modality due to the deficiency of such polarimetric imaging devices. In this paper, we have inspected industrial carbon fiber composites using a portable and handheld imaging scanner in which the THz polarizations of two orthogonal channels are simultaneously captured by two photoconductive antennas.

Safe Hypofractionation Amid Diverse Technologies: Using Teamwork to Manage the Complexity.

Radiation oncology caregivers worldwide are dedicated to advancing cancer treatment with the ultimate goal of eradicating the disease. Recognizing the inherent complexity of cancer treatment using hypo-fractionation radiotherapy (HFRT), these caregivers are committed to exploring avenues for progress and providing personalized care to each patient. Strong teams and effective workflows are an essential component to implementing safe HFRT.

On the Computation of Mean and Variance of Spatial Displacements.

This paper studies the problem of computing an average (or mean) displacement from a set of given spatial displacements using three types of parametric representations: Euler angles and translation vectors, unit quaternions and translation vectors, and dual quaternions. It is shown that the use of Euclidean norm in the space of unit quaternions reduces the problem to that of computing the mean for each quaternion component separately and independently. While the resulting algorithm is simple, a change in the sign of a unit quaternion could lead to an incorrect result.

On the Construction of Confidence Regions for Uncertain Planar Displacements.

This paper studies the statistical concept of confidence region for a set of uncertain planar displacements with a certain level of confidence or probabilities. Three different representations of planar displacements are compared in this context and it is shown that the most commonly used representation based on the coordinates of the moving frame is the least effective. The other two methods, namely the exponential coordinates and planar quaternions, are equally effective in capturing the group structure of SE(2).
