An Experimental Study on Applying Metamorphic Testing in Machine Learning Applications

Machine learning techniques have been successfully employed in various areas and, in particular, for the development of healthcare applications, aiming to support in more effective and faster diagnostics (such as cancer diagnosis). However, machine learning models may present uncertainties and errors. Errors in the training process, classification, and evaluation can generate incorrect results and, consequently, to wrong clinical decisions, reducing the professionals' confidence in the use of such techniques. Similar to other application domains, the quality should be guaranteed to produce more reliable models capable of assisting health professionals in their daily activities. Metamorphic testing can be an interesting option to validate machine learning applications. Using this testing approach is possible to define relationships that define changes to be made in the application's input data to identify faults. This paper presents an experimental study to evaluate the effectiveness of metamorphic testing to validate machine learning applications. A Machine learning application to verify breast cancer diagnostic was developed, using an available dataset composed of 569 samples whose data were taken from breast cancer images, and used as the software under test, in which the metamorphic testing was applied. The results indicate that metamorphic testing can be an alternative to support the validation of machine learning applications.

Ab initio electronic stopping power for protons in Ga0.5In0.5P/GaAs/Ge triple-junction solar cells for space applications

Motivated by the radiation damage of solar panels in space, firstly, the results of Monte Carlo particle transport simulations are presented for proton impact on triple-junction Ga0.5In0.5P/GaAs/Ge solar cells, showing the proton projectile penetration in the cells as a function of energy. It is followed by a systematic ab initio investigation of the electronic stopping power for protons in different layers of the cell at the relevant velocities via real-time time-dependent density functional theory (RT-TDDFT) calculations. The electronic stopping power is found to depend significantly on different channeling conditions, which should affect the low velocity damage predictions, and which are understood in terms of impact parameter and electron density along the path. Additionally, we explore the effect of the interface between the layers of the multilayer structure on the energy loss of a proton, along with the effect of strain in the lattice-matched solar cell. Both effects are found to be small compared with the main bulk effect. The interface energy loss has been found to increase with decreasing proton velocity, and in one case, there is an effective interface energy gain.

Factors associated with patient satisfaction towards pharmacy services among out-patients attending public health clinics: Questionnaire development and its application

Introduction: Patient satisfaction is widely used to measure quality of healthcare by identifying potential areas for improvement. Aim of study is to assess patient satisfaction towards pharmacy services and its associated factors using newly developed questionnaire among outpatients attending public health clinics. Materials and Methods: Public Health Clinic Patient Satisfaction Questionnaire (PHC-PSQ) towards pharmacy services was developed using exploratory factor analysis and Cronbach's α. A cross-sectional study was conducted among 400 patients visiting the pharmacy in three randomly selected public health clinics recruited via systematic random sampling. Data was collected using a set of questionnaire including PHC-PSQ. Factors associated with patient satisfaction was analysed using multiple linear regression. Results: Final PHC-PSQ consisted of three domains (administrative competency, technical competency and convenience of location) and 22 items with 69.9% total variance explained. Cronbach's α for total items was 0.96. Total mean score for patient satisfaction was 7.56 (SD 1.32). Older age and higher education were associated with lower patient satisfaction mean score. Patients who had visited the pharmacy more than once in the past three months, perceived to be in better health status and had a more correct general knowledge of pharmacists expressed higher patient satisfaction mean score. Conclusions: PHC-PSQ is a newly developed tool to measure patient satisfaction towards pharmacy services in public health clinics in Malaysia. Patient satisfaction was relatively high. Age, education, frequency of visit, self-perceived health status and general knowledge of pharmacists were factors significantly associated with patient satisfaction.

The applicability of eDNA metabarcoding approaches for sessile benthic surveying in the Kimberley region, north-western Australia

The application of environmental DNA technologies is a promising new approach to rapidly audit biodiversity across large-scale, remote regions. Here, we examine the efficacy of a dual-assay eDNA metabarcoding approach for sessile benthic bioassessments in the turbid waters of the Lalang-garram <a>Marine Parks</a>, in the inshore Kimberley region, north-western Australia. We ask three principal questions: 1. Is the eDNA released by sessile benthic taxa (i.e. hard and soft corals, sponges and tunicates) locally detectable? 2. What level of taxonomic resolution is afforded by eDNA metabarcoding using the ITS2 region? and 3. How well does eDNA metabarcoding compare to conventional benthic survey techniques, such as belt and point-intercept transects? We report that a dual-assay eDNA metabarcoding approach is capable of detecting approximately 70% of the local benthic taxa (i.e. at a species, genus level etc) identified at the surveyed locations. It is, however, not as effective at the individual/population level, detecting only approximately 40% of unique amplicon sequence variant (ASV) signals released by an array of individual benthic organisms at the surveyed locations. In examining the efficacy and resolution of the applied ITS2 metabarcoding markers for bioassessments, we report large gaps in the variety of publicly available benthic ITS2 reference sequence data, limiting our ability to provide robust taxonomic assignments. These findings highlight the need to extend ITS2 databases for greater regional representation. Until this is adequately addressed, we recommend that investigating taxonomic assignments to a genus-level is the most robust approach to benthic monitoring using eDNA. Lastly, we found eDNA metabarcoding and conventional belt-transect surveys each detected numerous unique hard coral genera, indicating that a combined approach provides the most effective way to audit benthic biodiversity. Furthermore, eDNA metabarcoding had the power to distinguish similar diversity trends between sites to that determined by the belt-transect methodology, validating the application of eDNA metabarcoding as either a stand-alone, or complementary technique for assessing sessile benthic taxa.

A multi-tiered sequence capture strategy spanning broad evolutionary scales: application for phylogenetic and phylogeographic studies of orchids

With over 25,000 species, the drivers of diversity in the Orchidaceae remain to be fully understood. Here we outline a multi-tiered sequence capture strategy aimed at capturing 100's of loci to enable phylogenetic resolution from subtribe to subspecific levels in orchids of the tribe Diurideae. For the probe design, we mined subsets of 18 transcriptomes, to give five target sequence sets aimed at the tribe (Sets 1 & 2), subtribe (Set 3), and within subtribe levels (Sets 4 & 5). Analysis included alternative de novo and reference-guided assembly, before target sequence extraction, annotation and alignment, and application of a homology-aware k-mer block phylogenomic approach, prior to phylogenetic inference using maximum-likelihood. Our evaluation considered 87 taxa in two test datasets: 67 samples spanning the tribe, and 72samples involving 24 closely related Caladenia species. The tiered design achieved high target loci recovery (>89%), with the median number of recovered loci in Sets 1–5 as follows: 212, 219, 816, 1024, and 1009, respectively. Interestingly, as a first test of the homologous k-mer approach for targeted sequence capture data, our study revealed its potential for enabling robust phylogenetic species tree inferences. Specifically, we found matching, and in one case improved phylogenetic resolution within species complexes, compared to conventional phylogenetic analysis involving target gene extraction. Our findings indicate that a customised multi-tiered sequence capture strategy, in combination with promising yet under-utilized phylogenomic approaches, will be effective for groups where interspecific divergence is recent, but information on deeper phylogenetic relationships is also required.
