“… 17 , 23 The AMS and MSLQ have been previously used in medical education research both internationally and in New Zealand. 24 – 26 In a study by Mitchell 26 , the construct validity of the AMS has also been investigated among a University of Auckland medical student population and suggested that the AMS was appropriate for the assessment of motivation among medical students.…”

Objective:The purpose of this study was to determine the impact of a revised curriculum on medical student academic motivation, burnout, and quality of life.Methods:This cross-sectional comparative study involved 2 medical school cohorts of second year and fourth year medical students at The University of Auckland: a cohort under a traditional curriculum (n = 437) and a cohort under a revised curriculum (n = 446). Participants completed self-reported questionnaires measuring academic motivation, burnout, and quality of life. Two multivariate analyses of covariance (MANCOVAs) were conducted.Results:The response rate was 48%. No statistically significant differences were found between curriculum cohorts for mean scores of academic motivation, personal burnout, and quality of life. However, differences were found when comparing preclinical medical students and students in their clinical years of training. In comparison with Year 2 medical students, the MANCOVA for Year 4 students showed a significant main effect for the revised curriculum with respect to both physical and environmental quality of life.Conclusions:A revised medical curriculum had a differential effect on quality of life for Year 4 students in the latter years of medical school who are based in a clinical learning environment.

“…We implement the three haplotype-based membership inference algorithms in Python 2.7 ( Van Rossum and Drake, 1995 ) [utilizing the packages sympy.solve ( Meurer et al , 2017 ) and pulp. LpProblem ( Mitchell et al , 2011 )], and evaluate them using an artificially created target genome database comprising 500 randomly selected human genomes (i.e. 1000 haplotypes) from the 1000 Genomes Project data ( GenomeAsia100K Consortium, 2015 ).…”

Motivation The availability of human genomic data, together with the enhanced capacity to process them, is leading to transformative technological advances in biomedical science and engineering. However, the public dissemination of such data has been difficult due to privacy concerns. Specifically, it has been shown that the presence of a human subject in a case group can be inferred from the shared summary statistics of the group, e.g. the allele frequencies, or even the presence/absence of genetic variants (e.g. shared by the Beacon project) in the group. These methods rely on the availability of the target’s genome, i.e. the DNA profile of a target human subject, and thus are often referred to as the membership inference method. Results In this article, we demonstrate the haplotypes, i.e. the sequence of single nucleotide variations (SNVs) showing strong genetic linkages in human genome databases, may be inferred from the summary of genomic data without using a target’s genome. Furthermore, novel haplotypes that did not appear in the database may be reconstructed solely from the allele frequencies from genomic datasets. These reconstructed haplotypes can be used for a haplotype-based membership inference algorithm to identify target subjects in a case group with greater power than existing methods based on SNVs. Availability and implementation The implementation of the membership inference algorithms is available at https://github.com/diybu/Haplotype-based-membership-inferences.

“…The scikit-image image processing library (Van der Walt et al, 2014) was used to read in our 8-bit image files as NumPy arrays (Walt et al, 2011) in order to perform calculations. The PuLP linear optimization library (Mitchell et al, 2011) was used to define each optimization model and call the GNU Linear Programming Kit (GLPK), version 4.62. GLPK is an open-source C implementation of primal and dual simplex methods used to solve linear programs (Makhorin et al, 2006).…”

Multi-Angle Plasma Focused Ion Beam (FIB) Curtaining Artifact Correction Using a Fourier-Based Linear Optimization Model

2018

We present a flexible linear optimization model for correcting multi-angle curtaining effects in plasma focused ion beam scanning electron microscopy (PFIB-SEM) images produced by rocking-polishing schemes. When PFIB-SEM is employed in a serial sectioning tomography workow, it is capable of imaging large three-dimensional volumes quickly, providing rich information in the critical 10–100 nm feature length scale. During tomogram acquisition, a “rocking polish” is often used to reduce straight-line “curtaining” gradations in the milled sample surface. While this mitigation scheme is effective for deep curtains, it leaves shallower line artifacts at two discretized angles. Segmentation and other automated processing of the image set requires that these artifacts be corrected for accurate microstructural quantification. Our work details a new Fourier-based linear optimization model for correcting curtaining artifacts by targeting curtains at two discrete angles. We demonstrate its capabilities by processing images from a tomogram from a multiphase, heterogeneous concrete sample. We present methods for selecting the parameters which meet the user’s goals most appropriately. Compared to previous works, we show that our model provides effective multi-angle curtain correction without introducing artifacts into the image, modifying non-curtain structures or causing changes to the contrast of voids. Our algorithm can be easily parallelized to take advantage of multi-core hardware.
