Predicting with Proxies: Transfer Learning in High Dimension
Authors: Bastani Hamsa 
Published: October 2020

Predictive analytics is increasingly used to guide decision making in many applications. However, in practice, we often have limited data on the true predictive task of interest and must instead rely on more abundant data on a closely related proxy predictive task. For example, e-commerce platforms use abundant customer click data (proxy) to make product recommendations rather than the relatively sparse customer purchase data (true outcome of interest); alternatively, hospitals often rely on medical risk scores trained on a different patient population (proxy) rather than their own patient population (true cohort of interest) to assign interventions. Yet, not accounting for the bias in the proxy can lead to suboptimal decisions. Using real data sets, we find that this bias can often be captured by a sparse function of the features. Thus, we propose a novel two-step estimator that uses techniques from high-dimensional statistics to efficiently combine a large amount of proxy data and a small amount of true data. We prove upper bounds on the error of our proposed estimator and lower bounds on several heuristics used by data scientists; in particular, our proposed estimator can achieve the same accuracy with exponentially less true data (in the number of features d). Finally, we demonstrate the effectiveness of our approach on e-commerce and healthcare data sets; in both cases, we achieve significantly better predictive accuracy as well as managerial insights into the nature of the bias in the proxy data.

Published: October 2020

Background/Aims Literature suggests that aerobic exercise improves cognitive impairments post stroke. This systematic review was conducted to analyse evidence on the effectiveness of aerobic exercise in improving post-stroke cognitive impairments. Methods Online databases (PubMed, EMBASE and Web of Science) were systematically searched from inception until 13 July 2017 using the keywords stroke/exercise/cognition. Clinical trials that met the inclusion criteria were assessed for methodological quality using the PEDro scale. Extracted data were synthesised for evidence. Results A total of seven studies met the inclusion criteria. Participants in most of the studies were aged over 60 years and the majority had ischaemic stroke. The most commonly used measure for assessing cognition was the Mini Mental State Examination. The majority of studies included moderate to high intensity exercise (50–70% of VO2max) for 30–60 minutes three to five times per week. There is moderate evidence that aerobic exercise enhances global cognitive function, attention and working memory. Evidence that aerobic exercise improves memory, levels of brain-derived neurotrophic factor and executive function is conflicting and limited. Conclusions Aerobic exercise is moderately effective in improving post-stroke cognitive impairments. More clinical trials are needed in view of the methodological limitations and paucity of existing studies.

Published: October 2020

Earth has a long geological history and palaeo-wildfire is one of the key factors which is responsible for the evolution and extinction of our earth systems. The most important extinction of our earth systems is the Permian-Triassic mass extinction. The objective of this paper is to evaluate the product of wildfire in terms of distribution and occurrences from the Late Permian North China basin. Fourteen rock samples were collected from a drill core of Hanxing Coalfield of North China basin. The samples were analyzed by macro and micro petrography, Scanning Electron Microscopy (SEM), Gas Chromatography (GC) and Gas Chromatography–Mass Spectrometry (GC-MS) in order to study the evidence of wildfire. Charcoal (inertinite) particles are observed in the samples, which established the occurrences of wildfire during the upper Middle and Late Permian time in North China. Additionally, high-molecular-weight Polycyclic Aromatic Hydrocarbons (PAHs) were detected in the studied samples which also reinforce the presence of palaeo–wildfire events in the North China basin in Late Permian due to the fact that these aromatic compounds were formed under high temperatures.

Published: October 2020

A novel, to the best of our knowledge, reflective sensor fabricated by simply sandwiching a homemade hollow core Bragg fiber (HCBF) between two single-mode fibers is proposed and demonstrated for the simultaneous measurement of the temperature and the strain. Different from traditional Fabry–Perot interferometer (FPI) sensors that can achieve only one-parameter sensing with inevitable cross-correspondence to other parameters, the proposed sensor based on the HCBF, which functions as an FPI-inducing FPI spectrum pattern and a weak waveguide confining light-inducing periodic envelope in reflection spectrum, ensures double-parameter sensing. For the HCBF-based reflective sensor, different sensing mechanisms lead to the various sensitivity values of temperature and strain (2.98 pm/°C, 19.4 pm/°C, 2.02 pm/µ

The Great Spiral Masquerader: A Case of Concurrent Secondary Syphilis and Autoimmune Hepatitis
Authors: Baliss Michelle , Kline Kevin , Khan Kashif , Stevenson Heather L. 
Published: October 2020

ABSTRACT
We describe a unique case of rash and acute hepatitis confounded by the presence of syphilis that created suspicion for syphilitic hepatitis, a rare and often misdiagnosed condition. Investigation concerning the etiology alternatively lead to the diagnosis of 2 concomitant conditions: active autoimmune hepatitis and secondary syphilis. To our knowledge, this is the first description in the literature of the simultaneous occurrence of secondary syphilis and autoimmune hepatitis. This case serves to increase the recognition of the clinical characteristics and diagnostic challenges of syphilitic hepatitis and to discuss the potential role of pathogens in the induction of autoimmunity.

Abstract
Fort-Vanmeerhaeghe, A, Milà-Villarroel, R, Pujol-Marzo, M, Arboix-Alió, J, and Bishop, C. Higher vertical jumping asymmetries and lower physical performance are indicators of increased injury incidence in youth team-sport athletes. J Strength Cond Res 36(8): 2204–2211, 2022—To date, the literature about the association between injury-risk factors and actual injury incidence in young elite team-sports athletes is scarce. The main objective of this study was to examine how modifiable factors may affect injury incidence. Eighty-one young elite team-sports athletes (age: under-14 to under-18) performed the countermovement jump (CMJ), a single leg CMJ (SLCMJ), the one-legged hop test (OLHT), a 30-m sprint test, the V-cut test, a repeated sprint ability, and the 30-15 intermittent fitness test (IFT) during the pre-season period. Interlimb asymmetries were calculated for SLCMJ and OLHT. Injuries were recorded prospectively for the entirety of the 2017–2018 season. Comparison of injury and noninjury data was performed using a two-way analysis of variance (ANOVA). Results of the ANOVA according to injury showed significant differences in CMJ (p = 0.01), SLCMJ on the lowest performing limb (p = 0.03), and SLCMJ asymmetry (<0.001). Sex × injury interaction was significant from CMJ (p = 0.018) and 30-15 IFT (p = <0.001). In conclusion, this study indicated that athletes with greater interlimb asymmetries, less vertical jump capacity, and lower intermittent aerobic fitness had a greater predisposition to injury. Therefore, monitoring CMJ, aerobic performance, and interlimb asymmetries is recommended given their sensitivity to detect significant differences between injured and healthy youth athletes.

Vigh-Larsen, JF, Haverinen, MT, Panduro, J, Ermidis, G, Andersen, TB, Overgaard, K, Krustrup, P, Parkkari, J, Avela, J, Kyröläinen, H, and Mohr, M. On-ice and off-ice fitness profiles of elite and U20 male ice hockey players of two different national standards. J Strength Cond Res 34(12): 3369–3376, 2020—Differences in body composition and performance were investigated between elite and U20 male ice hockey players of 2 different national standards. One hundred seventy-nine players were recruited from the highest Finnish (n = 82) and Danish (n = 61) national level, as well as from 1 U20 team from Finland (n = 19) and Denmark (n = 17). Body composition and countermovement jump performance (CMJ) were measured off-ice in addition to on-ice assessments of agility, 10- and 30-m sprint performance, and endurance capacity (the maximal Yo-Yo Intermittent Recovery Level 1 Ice Hockey Test, Yo-Yo IR1-IHmax). Large differences in on-ice performances were demonstrated between Finnish and Danish elite players for agility, 10- and 30-m sprint performance (2–3%, P ≤ 0.05), and Yo-Yo IR1-IHmax performance (15%, P ≤ 0.05). By contrast, no differences (P > 0.05) were present between elite players for CMJ ability or body composition. However, elite players possessed more body and muscle mass than U20 players. Finally, the Finnish U20 cohort had a similar performance level as the Danish elite players and superior 10-m sprint performance, whereas the Danish U20 level was inferior to the other groups in every performance assessment (P ≤ 0.05). In conclusion, on-ice speed and endurance differ markedly between elite players of 2 different national standards with no distinction in body composition or CMJ ability. Moreover, the most consistent difference between U20 and senior elite players was related to body and muscle mass. These results highlight the usefulness of on-ice assessments and suggest the importance of on-ice high-intensity training in elite players in addition to training targeted the development of lean body mass in youth prospects.
Genome Sequence of the Banana Aphid,Pentalonia nigronervosaCoquerel (Hemiptera: Aphididae) and Its Symbionts
Authors: Mathers Thomas C , Mugford Sam T , Hogenhout Saskia A , Tripathi Leena 
Published: October 2020

AbstractThe banana aphid, Pentalonia nigronervosa Coquerel (Hemiptera: Aphididae), is a major pest of cultivated bananas (Musa spp., order Zingiberales), primarily due to its role as a vector of Banana bunchy top virus (BBTV), the most severe viral disease of banana worldwide. Here, we generated a highly complete genome assembly of P. nigronervosa using a single PCR-free Illumina sequencing library. Using the same sequence data, we also generated complete genome assemblies of the P. nigronervosa symbiotic bacteria Buchnera aphidicola and Wolbachia. To improve our initial assembly of P. nigronervosa we developed a k-mer based deduplication pipeline to remove genomic scaffolds derived from the assembly of haplotigs (allelic variants assembled as separate scaffolds). To demonstrate the usefulness of this pipeline, we applied it to the recently generated assembly of the aphid Myzus cerasi, reducing the duplication of conserved BUSCO genes by 25%. Phylogenomic analysis of P. nigronervosa, our improved M. cerasi assembly, and seven previously published aphid genomes, spanning three aphid tribes and two subfamilies, reveals that P. nigronervosa falls within the tribe Macrosiphini, but is an outgroup to other Macrosiphini sequenced so far. As such, the genomic resources reported here will be useful for understanding both the evolution of Macrosphini and for the study of P. nigronervosa. Furthermore, our approach using low cost, high-quality, Illumina short-reads to generate complete genome assemblies of understudied aphid species will help to fill in genomic black spots in the diverse aphid tree of life.

Introduction: Rice-field rats are one of the most important pests because it can give large losses in all planting seasons including the storehouse. Synthetic rodenticide is the most commonly used of chemical technique for controlling rice-field rats. The application of these materials indirectly causes negative impacts; one of them is for the environment. As an alternative for controlling rice-field rats, natural materials can be used as a repellent. Objective: to examine the effects of methanol extract of Plumeria rubra leaves on metabolism, daily activity patterns, and its potency as a repellent of the rice-field rat. Methods: The experiments were conducted at the Laboratory of Pests, Universitas Padjadjaran involves choice test (T-maze arena), and the Laboratory of Rats, Indonesian Institute for Rice Research involves no-choice test (metabolic cage) from February until May 2019. The observations including food (g), water consumption (ml), feces production (g), urine production (ml), body weight (g), and its changes (%), also the daily activities (time spent for locomotion, foraging, and resting).The treatment was done with three replications for twelve mature male and twelve mature non-pregnant females. Data experiments analysis followed by a T-test. Results: Rice-field rats on the T-Maze arena avoided consuming food and beverage that close to methanol extract of Plumeria rubra leaves treatment. The treatment of methanol extract of Plumeria leaves in metabolic cage caused metabolic disorder of rice-field rat, which was significantly indicated by the decrease of the average consumption of food by 2.28 g and excretion of feces by 0.34 g, and also the increase of average consumption of beverage by 3.89 ml, excretion of urine by 3.15 ml, and body weight by 6.67 g. The treatment also caused daily activity patterns disorder of rice-field rats, which was significantly indicated by the increase of the average percentage of time for movement activities (locomotion) by 7.64 % and the decrease of time for eating and drinking activities (foraging) by 16.46 %. Conclusion: Methanol extract of Plumeria leaves affects a repellent for the rice-field rat.
Can fallen trees enhance aboveground biomass estimation? A proposal for the Brazilian Atlantic Forest
Authors: FONSÊCA NATHAN CASTRO , Meunier Isabelle Maria Jacqueline , Lins-e-Silva Ana Carolina Borges 
Published: October 2020

Introduction: Estimating aboveground biomass (AGB) in protected forests is a challenge, due to high costs and legal restrictions for direct assessments, and also to frequently weak estimation provided by general AGB equations. Objective: We propose a new approach that uses dead fallen trees (DFTs) to improve AGB estimation. We aim to analyse if the adjustment of allometric models based on DFTs provides a suitable local equation for AGB estimation or helps to validate existing pantropical or regional allometric equations. Methods: The study was carried out at the Dois Irmãos State Park (PEDI), Pernambuco, Northeast Brazil. Along 4 000 m, using the line intersect technique, we sampled 37 recent dead fallen trees ranging from 7.6 to 92.3 cm in diameter and from 8.6 to 29.4 m in height. Nine models were adjusted, and the best equation (local) was compared to regional and pantropical equations. Results: One equation (AGBkg= 1.5292* DBH2.0601*TH-0.2187) produced biomass estimates which did not differ from the observed values (P > 0.05). Differently from the others, this equation overestimated AGB in only 2.8 % and, along with other parameters of analysis (R2adj and Syx %) had the best overall performance. Analysing the performance of the local equation versus available equations for estimating AGB, we found that only the local and the pantropical equations by Pearson et al. (2005) estimated values that were not significantly different from observed values. However, the local equation is more appropriate for local estimation of AGB, since it has the lowest RSME and CV. Conclusions: Based on the proposed approach, we were able to offer a local equation for tree AGB estimation based on fallen trees. The DFT method is efficient regarding time and costs, avoiding tree logging in protected forests and helps to guide the choice of a proper equation for forest AGB demands.
TRAUMA-SENSITIVE PEDAGOGY & PRACTICE NEWSLETTER 1 (OF 2)

Published: October 2020

This publication includes the first of two newsletters published in this issue of Art/Research International. This second newsletter is followed by a commentary and references for both newsletters.
Attentive to local and global mental health realities and the emergent need to provide intercultural mental health perspectives, resources, and methods that work across cultures in school contexts, I (the first author) conducted a participatory poetic inquiry, “Image, Body, and Voice: Supporting Girls’ Sense of Wellbeing,” with grade-6 girls in an inner-city school in Alberta. It sought to: (i) meet new Teacher Quality Standards (TQS) “to build positive and productive relationships with students [and] peers” (AB Education, 2018, p. 4); and (ii) be “aware of and facilitate responses to the emotional and mental health needs of students” (p. 6). I was guided by the following research question: In what ways might girls’ experiences with art-integrated activities and body-centred methods inform educators about pedagogical practice and mental health interventions?
Findings indicated the transdisciplinary praxis that emerged—arts-based, contemplative and somatic methods—enhanced the girls’ sense of self and wellbeing. The youth reported that these activities had explicit value: sharing circles used for check-ins and - outs, ceremony—which welcomed witnessing—relational and body-centred practices, and one-on-one time with the PI. The life-size body maps as research creation illustrated that the participants learned to externalize sensations and emotions in a safe way, aiding them in the development of skills needed for emotional self-regulation. Body maps broadly defined are life-size body images, while body mapping is the process of creating body maps using collage, photography, painting, or other arts-integrated methods to visually symbolize aspects of people’s lives, their bodies, and their worlds.
Funding from Research Impact Canada, VP Research & Innovation University of Alberta and the Kule Institute for Advanced Study aided to mobilize evidence-informed knowledge from this research through professional community engagement with pre- service teachers at a full-day workshop. Presenters at the workshop were members of a Community of Professional Practice (COPP) where the activities of educational research and trauma-sensitive practices were shared, including culturally aware methods for diverse populations. This newsletter reflects one of two events and two research creation artifacts provided as follow up to the attendees.
