description: Several computer vision applications such as person search or online fashion rely on human description. The use of instance-level human parsing (HP) is therefore relevant since it localizes semantic attributes and body parts within a person. But how to characterize these attributes? To our knowledge, only some single-HP datasets describe attributes with some color, size and/or pattern characteristics. There is a lack of dataset for multi-HP in the wild with such characteristics. In this article, we propose the dataset CCIHP based on the multi-HP dataset CIHP, with 20 new labels covering these 3 kinds of characteristics. In addition, we propose HPTR, a new bottom-up multi-task method based on transformers as a fast and scalable baseline. It is the fastest method of multi-HP state of the art while having precision comparable to the most precise bottom-up method. We hope this will encourage research for fast and accurate methods of precise human descriptions.

description: We present integral field spectroscopy of two selected zones in the Orion Nebula obtained with the Potsdam Multi-Aperture Spectrophotometer (PMAS), covering the optical spectral range from 3500 to 7200 A and with a spatial resolution of 1". The observed zones are located on the prominent Bright Bar and on the brightest area at the northeast of the Orion South cloud, both containing remarkable ionization fronts. We obtain maps of emission line fluxes and ratios, electron density and temperatures, and chemical abundances. We study the ionization structure and morphology of both fields, which ionization fronts show different inclination angles with respect to the plane of the sky. We find that the maps of electron density, O+/H+ and O/H ratios show a rather similar structure. We interpret this as produced by the strong dependence on density of the [OII] lines used to derive the O+ abundance, and that our nominal values of electron density-derived from the [SII] line ratio-may be slightly higher than the appropriate value for the O+ zone. We measure the faint recombination lines of OII in the field at the northeast of the Orion South cloud allowing us to explore the so-called abundance discrepancy problem. We find a rather constant abundance discrepancy across the field and a mean value similar to that determined in other areas of the Orion Nebula, indicating that the particular physical conditions of this ionization front do not contribute to this discrepancy.

Effect of amino acid limitation and supplementation in Chinese hamster ovary fed-batch cultures
Creators: name: Ghaffari, Navid
Publisher: name: University of British Columbia
Year: 2015

description: Fed-batch processes are the industrial norm for the production of recombinant proteins such as monoclonal antibodies (MAb) from Chinese hamster ovary (CHO) cells. Optimization of such processes is an important objective of industry process development groups. Amino acid availability is a key factor that is controlled to achieve the desired product yield and quality. In order to improve fed-batch productivity, the individual effects of limiting the three depleted amino acids were investigated for three antibody expressing CHO cell lines. Specifically, the effects of limiting glutamine, asparagine and cysteine on the cell growth, metabolism, antibody productivity and quality were investigated. Cysteine limitation was found to be detrimental to both the cell proliferation and the productivity for all three CHO cell lines. In contrast, asparagine limitation had no significant effect on either their growth or productivity. Glutamine limitation resulted in a reduction in growth but not in cell specific productivity, again for all three cell lines. Neither glutamine nor asparagine limitation significantly affected the MAb glycosylation. However, the fucosylation ratio was reduced in the absence of cysteine. It was confirmed that cysteine is a rate limiting factor for the productivity and growth of the three CHO cell lines. Replenishing cysteine after 1 day of the limitation allowed the cells to regain their growth and productivity; however, this was not observed after 2 days of cysteine limitation. Under cysteine limitation there was increased oxidative damage to the mitochondria, possibly caused by reduced synthesis of co-enzyme A which is essential for functionality of the TCA cycle. Finally, a fed-batch protocol was developed to improve the MAb productivity of CHO-DXB11 cells and the results were compared to the results with a commercial feed. Although use of the commercial feed resulted in higher maximum cell and final MAb concentrations, maintaining the levels of cysteine yielded cell specific production rates that were comparable to the commercial feed culture. Overall, the results of this study showed that amino acid limitations have varied effects on the performance of CHO cell cultures, such that it is important to focus process development efforts on the critical amino acids.

description: How human-like do conversational robots need to look to enable long-term human-robot conversation? One essential aspect of long-term interaction is a human's ability to adapt to the varying degrees of a conversational partner's engagement and emotions. Prosodically, this can be achieved through (dis)entrainment. While speech-synthesis has been a limiting factor for many years, restrictions in this regard are increasingly mitigated. These advancements now emphasise the importance of studying the effect of robot embodiment on human entrainment. In this study, we conducted a between-subjects online human-robot interaction experiment in an educational use-case scenario where a tutor was either embodied through a human or a robot face. 43 English-speaking participants took part in the study for whom we analysed the degree of acoustic-prosodic entrainment to the human or robot face, respectively. We found that the degree of subjective and objective perception of anthropomorphism positively correlates with acoustic-prosodic entrainment.

Understandings of emotional salience in a preschool classroom
Creators: name: Wallberg, Pamela
Publisher: name: University of British Columbia
Year: 2015

description: The purpose of this research was to examine the ways in which preschoolers use artistic, kinaesthetic and linguistic modes of expression to recognize, label and understand feeling words of varied salience within a classroom environment. The ways in which a multi-modal approach towards emotional literacy in the classroom supported emotional literacy is examined. The research site was an urban preschool classroom in the lower mainland of British Columbia. Seventeen three-and-four-year-old children created drawings, kinaesthetically posed, and discussed feeling words of varied salience: ‘calm’, ‘happy’, and ‘ecstatic’, which served as the primary data source, supplemented with teacher observation notes. Analysis found that each mode offered unique insights into how young children recognize, understand and label feeling words of varied salience. Limitations of this study are discussed and suggestions for further research are offered.

Can memoir contribute to a more collaborative approach to treating eating disorders that respects and includes the family?
Creators: name: Robinson, Cathrine P.
Publisher: name: University of British Columbia
Year: 2015

description: Eating disorders are on the rise among adolescents in North America along with an increase in mortality rates due to complications associated with the disorder. Eating disorders also have a profound effect on families. Feelings of anxiety and depression, stress, and burnout are commonly associated with caring for an adolescent with an eating disorder. In addition to this, many families feel isolated and blamed by health-care professionals and receive little support, collaboration, or education about the disorder. Simultaneously, health-care professionals also struggle with feelings of frustration, stress, burnout, and judgmental attitudes towards families due to the lack of knowledge and understanding of eating disorders. There are gaps in the knowledge of health-care professionals, both in terms of understanding the disorder, and supporting patients and families of adolescents with eating disorders. This dissertation endeavoured to fill this gap. My main research question was “what contributions arise from writing a memoir about the impact on a family of a female adolescent with an eating disorder and the family’s encounters with health-care professionals?” My sub-questions were: a) “what is the outcome of sharing that memoir with health-care professionals?” and b) “how can this memoir contribute to a collaborative approach to treating eating disorders that respects and includes the family?” A qualitative study encompassing a two part design was used. Part one comprised the creation of a memoir of my journey through my daughter’s experience of an eating disorder from my perspectives as a mother, my interactions with health-care professionals, and my role as a health-care professional caring for adolescents with eating disorders. Part two involved the reading of the memoir by seven participants, all pediatric nurses whose practice included the care of adolescents with eating disorders. Through an online focus group, participants responded to pre-determined questions and to each others answers. Through this study, the value of a memoir was apparent as a way for nurses to reflect on their caring practice and to identify barriers to providing effective care. The memoir proved to be a catalyst for bringing additional resources to support nurses’ caring practice.

description: In video surveillance applications, person search is a challenging task consisting in detecting people and extracting features from their silhouette for re-identification (re-ID) purpose. We propose a new end-to-end model that jointly computes detection and feature extraction steps through a single deep Convolutional Neural Network architecture. Sharing feature maps between the two tasks for jointly describing people commonalities and specificities allows faster runtime, which is valuable in real-world applications. In addition to reaching state-of-the-art accuracy, this multi-task model can be sequentially trained task-by-task, which results in a broader acceptance of input dataset types. Indeed, we show that aggregating more pedestrian detection datasets without costly identity annotations makes the shared feature maps more generic, and improves re-ID precision. Moreover, these boosted shared feature maps result in re-ID features more robust to a cross-dataset scenario.

Investigation of the effect of genetic polymorphism on the selection of antigenic peptides in major histocompatibility complexes
Creators: name: Kuan, Chia-Wei
Publisher: name: University of British Columbia
Year: 2015

description: Major histocompatibility complexes (MHCs) play a prominent role in the human adaptive immune system by presenting peptides derived from both host and foreign sources on the cell surface to T cells and eliciting appropriate immune responses during pathogenic invasions. MHC genes are highly polymorphic and the effect of polymorphism on the phenotype, known as an individual’s immunopeptidome, is still unclear. In this thesis, two independent but complementary methods of research were conducted to better understand the interaction between MHC alleles and the identities of peptides presented. First, the antigen presentation machinery was reconstructed in vitro for class II MHCs. This was accomplished by cloning and expressing HLA-DM and HLA-DR in insect cells and purifying the proteins via affinity and size exclusion chromatography. While DM was successfully purified, DR was not. However, once established the in vitro system will offer a novel way to deduce the preferred binding residues for any MHC allele or combinations of alleles, information traditional immunoprecipitation experiments cannot obtain. Next, in an effort to achieve higher confident assignments of class II MHC binding residues, a cell surface acid elution protocol was developed and performed on consanguineous B cell lines. Extracted peptides were identified using liquid chromatography tandem mass spectrometry. To verify that most surface peptides originated from MHCs, lentiviral shRNA was used to knock down HLA-A prior to acid elution, and the identities of peptides were compared to those obtained from the same cell line transduced with a non-targeting shRNA sequence. Results followed anticipated trends and validated the technique as a means to extract MHC peptides. Furthermore, the nature of consanguineous data sets allows for intra-experimental comparisons to decipher allele-specific peptides. Ultimately, these experiments present new ways to study the immunopeptidome and possess the potential to be applied to the vaccine development research field in the future.

Development and application of large-scale optogenetic mapping in the mouse cortex
Creators: name: Lim, Diana Heather
Publisher: name: University of British Columbia
Year: 2015

description: One of the major goals in neuroscience is to understand and map the connectivity of the brain. While this is no small undertaking, recent technological advances have allowed brain mapping to reach unprecedented levels. Optogenetic tools have been developed that permit selective manipulation and investigation of neural systems. Here, we have mapped in vivo intracortical activity in the mouse by combining arbitrary point optogenetic stimulation and regional voltage-sensitive dye (VSD) imaging. We first show that optogenetic photostimulation using channelrhodopsin-2 (ChR2) led to cortical maps that were similar to the maps generated with sensory stimulation. ChR2-evoked maps confirmed known intrahemispheric relationships (such as between barrel cortex and motor cortex) and known interhemispheric relationships (such as between homotopic areas). We used ChR2 point stimulation to map a number of cortical areas and used network analysis to examine relationships between cortical areas. We found asymmetrical connections between primary and secondary sensory cortex and defined the parietal association cortex as a hub node. We then applied this mapping method to map altered cortical connectivity in the early and late stages after a targeted cortical stroke (1 week post-stroke and 8 weeks post-stroke, respectively). Network analysis based on ChR2-evoked responses revealed a symmetrical bilateral sham network that was disrupted after stroke. At 1 week post-stroke, we observed wide-spread depression of ChR2-evoked activity that extended to the contralesional hemisphere. By 8 weeks post-stroke significant recovery was observed. When we considered the network as a whole, we found that scaling the ChR2-evoked activity from the stroke groups to match the sham group mean resulted in a relative distribution of responses that was indistinguishable from the sham group, suggesting network-wide down-scaling and connectional diaschisis after stroke. When connections within the peri-infarct were isolated, we did not observe equal down-scaling of responses after stroke. Our findings suggest that during recovery, most cortical areas undergo homeostatic upscaling, resulting in a relative distribution of responses that is similar to the pre-stroke (sham) network, albeit still depressed. However, recovery within the peri-infarct zone is heterogeneous and these cortical points do not follow the recovery scaling factor expected for the entire network.

description: On scales of days, the galactic cosmic ray (GCR) flux is affected by coronal mass ejections and corotating interaction regions (CIRs), causing so-called Forbush decreases and recurrent Forbush decreases (RFDs), respectively. We explain the properties and behavior of RFDs recorded at about 1 au that are caused by CIRs generated by solar wind high-speed streams (HSSs) that emanate from coronal holes. We employed a convection-diffusion GCR propagation model based on the Fokker-Planck equation and applied it to solar wind and interplanetary magnetic field properties at 1 au. Our analysis shows that the only two effects that are relevant for a plausible overall explanation of the observations are the enhanced convection effect caused by the increased velocity of the HSS and the reduced diffusion effect caused by the enhanced magnetic field and its fluctuations within the CIR and HSS structure. These two effects that we considered in the model are sufficient to explain not only the main signatures of RFDs, but also the sometimes observed "over-recovery" and secondary dips in RFD profiles. The explanation in terms of the convection-diffusion GCR propagation hypothesis is tested by applying our model to the observations of a long-lived CIR that recurred over 27 rotations in 2007-2008. Our analysis demonstrates a very good match of the model results and observations.

description: We analyze the Michelson-Morley experiment in a reference frame moving with constant proper acceleration. Interestingly, we find an expected fringe shift which depends not only on the interferometer's rate of acceleration, but also on its speed relative to a preferred absolute reference frame. While it has been repeatedly shown that no experiment performed in an inertial reference frame can detect that frame's absolute speed, the analysis in this paper suggests that by considering experiments in accelerated reference frames it may be possible to measure absolute speed after all.

Understanding the welfare of dairy animals during the transition between lactations

description: The cessation of milking, or dry off, is a regular management practice in dairy animals. This practice initiates a non lactating, or dry, period. Milking begins again after parturition. Provision of a dry period is done largely to improve milk production in the subsequent lactation, but also to address udder health issues (intramammary infections); therefore, the majority of literature focuses on these areas, and little consideration is given to the welfare of the individual animal. The goals of this thesis were to develop a better understanding of how common dry off methods, and the dry period itself, affect three components of animal welfare: biological functioning, affective states and natural behaviour in dairy cows and dairy goats. The first study in this dissertation explored how high producing dairy cows experience abrupt cessation of milking, a commonly utilized procedure. The results suggested that cows remain motivated to leave the pen around milking time, and that these cows leak milk, a risk factor for intramammary infections. Since dry off methodology is not well understood in dairy goats, the second study shifted towards describing dry off management used by goat producers. Although similarities to cow management exist, goat producers show more flexibility in decision making around dry off, sometimes opting to give high producing goats shorter, or even no, dry periods. Within this work, concerns were also identified regarding metabolic issues in goats (pregnancy toxemia and ketosis). Therefore, the final studies combined to explore the early identification of these issues in goats. The third study validated the use of data loggers on goats, allowing for automatic recording of lying behaviour. The fourth study applied these loggers to monitor the lying behaviour of goats during the dry period, and searched for links to pregnancy toxemia and ketosis. The results showed that at-risk goats increase their lying time and decrease their activity, making lying behaviour a promising indicator of metabolic issues. Finally, three key areas are discussed for future research, namely continued work in evaluating affective states in dairy animals, benchmarking of on-farm research results, and exploring the possibilities of deviating from standard annual lactation cycles.

description: In this paper we discuss the difficulties of mounting successful attack against crypto implementations when essential information is missing. We start with a detailed description of our attack against our own design, to highlight which information is needed to increase the success of an attack, i.e. we use it as a blueprint to the following attack against commercially available crypto chips. We would like to stress that our attack against our own design is very similar to what happens during certification e.g. according to Common Criteria Standard as in those cases the manufacturer needs to provide detailed information. When attacking the commercial designs without signing NDAs, we needed to intensively search the Internet for information about the designs. We cannot to reveal the private keys used by the attacked commercial authentication chips 100% correctly. Moreover, the missing knowledge of the used keys does not allow us to evaluate the success of our attack. We were able to reveal information on the processing sequence during the authentication process even as detailed as identifying the clock cycles in which the individual key bits are processed. To summarize the effort of such an attack is significantly higher than the one of attacking a well-known implementation.

Investigating undergraduate students' metacognitive transformations in an introductory organic chemistry course
Creators: name: Welsh, Ashley Jayne
Publisher: name: University of British Columbia

description: Recently, there has been a considerable number of curricular and pedagogical reform efforts in undergraduate science education to shift from traditional methods of lecturing and assessment to more active, learning-centered environments. While these shifts have introduced significant improvements in students’ conceptions of and engagement with science, the importance of how students learn science is often overshadowed. More specifically, there exists a need to address and enhance students’ metacognitive knowledge and regulation to assist them in effectively monitoring, evaluating, and planning their learning. This study investigated the catalysts that influenced students’ metacognitive transformations in an introductory organic chemistry course for biological science majors. A case study approach employing a combination of surveys, classroom observations, and interviews was used to investigate: 1) the catalysts (and their characteristics) influencing students’ metacognitive transformations; 2) the role of social environments in these transformations; and 3) the supports/barriers various groups of students perceived as influential to their metacognitive transformation. Analysis of the data corpus suggested performance-based assessment methods as the most influential to students’ metacognitive transformations and as overshadowing the resources designed to enhance students’ metacognition and self-efficacy. Despite the desire to engage students with their learning, the results from the SEMLI-S (Self-Efficacy and Metacognition Learning Inventory – Science) survey revealed a significant drop in students’ ability: to connect constructively with the course material; to effectively monitor, evaluate, and plan their learning; and to be confident in their ability to succeed in the course. Students attributed their lack of prerequisite content and metacognitive knowledge and the overwhelming quantity of course content as constraining their ability to actively engage in their learning. Some students, however, successfully employed metacognitive ii strategies and offered explicit descriptions of how and why they developed and/or adapted their learning strategies prior to or during the course of the semester. This study also provided insight into how students perceived and negotiated their learning, both individually and collaboratively. The findings from this study have implications on how undergraduate science curriculum and pedagogy might embrace learner-centered pedagogies to enhance students’ metacognition and self-efficacy.
A Correction to the Standard Galactic Reddening Map: Passive Galaxies as Standard Crayons

description: We present corrections to the Schlegel, Finkbeiner, Davis (SFD98) reddening maps over the Sloan Digital Sky Survey northern Galactic cap area. To find these corrections, we employ what we dub the "standard crayon" method, in which we use passively evolving galaxies as color standards by which to measure deviations from the reddening map. We select these passively evolving galaxies spectroscopically, using limits on the H alpha and O II equivalent widths to remove all star-forming galaxies from the SDSS main galaxy catalog. We find that by correcting for known reddening, redshift, color-magnitude relation, and variation of color with environmental density, we can reduce the scatter in color to below 3% in the bulk of the 151,637 galaxies we select. Using these galaxies we construct maps of the deviation from the SFD98 reddening map at 4.5 degree resolution, with 1-sigma error of ~ 1.5 millimagnitudes E(B-V). We find that the SFD98 maps are largely accurate with most of the map having deviations below 3 millimagnitudes E(B-V), though some regions do deviate from SFD98 by as much as 50%. The maximum deviation found is 45 millimagnitudes in E(B-V), and spatial structure of the deviation is strongly correlated with the observed dust temperature, such that SFD98 underpredicts reddening in regions of low dust temperature. Our maps of these deviations, as well as their errors, are made available to the scientific community as supplemental correction to SFD98 at http://www.peekandgraves2010.com.

description: Monte-Carlo generator with photon jets radiation in collinear regions for the process \eegg is described in detail. Radiative corrections in the first order of $α$ are treated exactly. Large leading logarithmic corrections coming from collinear regions are taken into account in all orders of $α$ by applying the Structure Function approach. Theoretical precision of the cross section with radiative corrections is estimated to be 0.2%. This process is considered as an additional tool to measure luminosity in forthcoming experiments with the CMD-3 detector at the $e^+e^-$ collider VEPP-2000.

description: Despite the great promise of machine-learning algorithms to classify and predict astrophysical parameters for the vast numbers of astrophysical sources and transients observed in large-scale surveys, the peculiarities of the training data often manifest as strongly biased predictions on the data of interest. Typically, training sets are derived from historical surveys of brighter, more nearby objects than those from more extensive, deeper surveys (testing data). This sample selection bias can cause catastrophic errors in predictions on the testing data because a) standard assumptions for machine-learned model selection procedures break down and b) dense regions of testing space might be completely devoid of training data. We explore possible remedies to sample selection bias, including importance weighting (IW), co-training (CT), and active learning (AL). We argue that AL---where the data whose inclusion in the training set would most improve predictions on the testing set are queried for manual follow-up---is an effective approach and is appropriate for many astronomical applications. For a variable star classification problem on a well-studied set of stars from Hipparcos and OGLE, AL is the optimal method in terms of error rate on the testing data, beating the off-the-shelf classifier by 3.4% and the other proposed methods by at least 3.0%. To aid with manual labeling of variable stars, we developed a web interface which allows for easy light curve visualization and querying of external databases. Finally, we apply active learning to classify variable stars in the ASAS survey, finding dramatic improvement in our agreement with the ACVS catalog, from 65.5% to 79.5%, and a significant increase in the classifier's average confidence for the testing set, from 14.6% to 42.9%, after a few AL iterations.
