Defining and Measuring Maintainability

Maintainability is a measure of the ease with which a software system can be maintained. In this paper we propose a quantitative definition of maintainability, and discuss means to estimate the maintainability of a software system on the basis of a static analysis of its deliverables. Such an estimation effort is useful inasmuchas it allows us to predict the maintainability of a software system at delivery time

Applicants with Prior Training.

Emergency medicine (EM) has its challenges, downsides, advantages, and accompanying lifestyle. Additionally, graduates of EM residency programs have abundant job opportunities. Accordingly, there is an increased interest in residency training in EM, even among residents with prior training. Transitioning from another specialty to EM can be complicated yet achievable, especially if EM is the transitioning physician's passion and career goal. Therefore, in this article, we elaborate on the transition process from another discipline to EM in light of changes in residency funding. We also explore the advantages and disadvantages of transitioning to EM with previous training in another specialty. Moreover, we expand on credit equivalencies for months already completed in another training programs, as well as the difficulties to be anticipated by transitioning physicians

Clerkships in Emergency Medicine.

Planning for clerkships in emergency medicine (EM) can be stressful, prolonged, and challenging. Therefore, medical students should start planning for them early. In this article, we offer guidance regarding several issues pertinent to the EM clerkship, such as the best time to schedule one (or more) during medical school, the most appropriate institution or program to schedule it, the process of selecting and applying for the clerkship, and the number of EM clerkships to consider. We will explain why an EM clerkship should be scheduled between June and October and the reason that 2 EM clerkships at different sites are sufficient for the majority of students. Additionally, we emphasize that clerkships in emergency departments associated with EM residency programs or with reputations for outstanding student teaching tend to be most beneficial. Above all, students interested in EM should attempt to leave a great impression after completing their clerkships by providing stellar patient care, demonstrating enthusiasm at all times, and maintaining professionalism. In turn, they will gain knowledge and clinical experiences that should prove valuable in their future

Experimental Investigation of Size Effects on the Thermal Conductivity of Silicon-Germanium Alloy Thin Films

We experimentally investigate the role of size effects and boundary scattering on the thermal conductivity of silicon-germanium alloys. The thermal conductivities of a series of epitaxially grown Si[subscript 1-x] Ge[subscript x] thin films with varying thicknesses and compositions were measured with time-domain thermoreflectance. The resulting conductivities are found to be 3 to 5 times less than bulk values and vary strongly with film thickness. By examining these measured thermal conductivities in the context of a previously established model, it is shown that long wavelength phonons, known to be the dominant heat carriers in alloy films, are strongly scattered by the film boundaries, thereby inducing the observed reductions in heat transport. These results are then generalized to silicon-germanium systems of various thicknesses and compositions; we find that the thermal conductivities of Si[subscript 1-x]Ge[subscript x] superlattices are ultimately limited by finite size effects and sample size rather than periodicity or alloying. This demonstrates the strong influence of sample size in alloyed nanosystems. Therefore, if a comparison is to be made between the thermal conductivities of superlattices and alloys, the total sample thicknesses of each must be considered.Sandia National Laboratories (Laboratory Directed Research and Development Program
