description: Preclassification of raw infrared spectra has often been neglected in scientific literature. Separating spectra of low spectral quality, due to low signal-to-noise ratio, presence of artifacts, and low analyte presence, is crucial for accurate model development. Furthermore, it is very important for sparse data, where it becomes challenging to visually inspect spectra of different natures. Hence, a preclassification approach to separate infrared spectra for sparse data is needed. In this study, we propose a preclassification approach based on Multiplicative Signal Correction (MSC). The MSC approach was applied on human and the bovine knee cartilage broadband Fourier Transform Infrared (FTIR) spectra and on a sparse data subset comprising of only seven wavelengths. The goal of the preclassification was to separate spectra with analyte-rich signals (i.e., cartilage) from spectra with analyte-poor (and high-matrix) signals (i.e., water). The human datasets 1 and 2 contained 814 and 815 spectra, while the bovine dataset contained 396 spectra. A pure water spectrum was used as a reference spectrum in the MSC approach. A threshold for the root mean square error (RMSE) was used to separate cartilage from water spectra for broadband and the sparse spectral data. Additionally, standard noise-to-ratio and principle component analysis were applied on broadband spectra. The fully automated MSC preclassification approach, using water as reference spectrum, performed as well as the manual visual inspection. Moreover, it enabled not only separation of cartilage from water spectra in broadband spectral datasets, but also in sparse datasets where manual visual inspection cannot be applied.

description: Die PCI ist die am häufigsten an epikardialen Herzgefäßen durchgeführte Prozedur zur Behandlung der KHK. Bei Patienten mit therapierefraktärer Angina pectoris stellt die therapeutische Arteriogenese eine aussichtsreiche Therapieoption dar. Im Großtiermodell am Schwein werden mittels Micro-CT-Analyse präexistente Kollateralgefäße und mittels MRT deren funktionelle Bedeutung nachgewiesen. Ein minimalinvasives Tiermodell mit perkutan interventionell induziertem kontrollierten CTO-artigen Koronargefäßverschluss und seriellen Verlaufsbeobachtungen am gleichen Tier ist die Voraussetzung für die Beurteilung und Stimulation von Kollateralwachstum und der Entwicklung eines natürlichen Koronararterien-bypasses am menschlichen Herzen. Bei stabiler Angina pectoris ist die angiographische Beurteilung und Stenosegradeinschätzung von mittelgradigen Koronarstenosierungen nicht ausreichend. Die Bestimmung der FFR ist indiziert, um die hämodynamische Relevanz und Interventionsnotwendigkeit dieser Koronareinengungen beurteilen und nicht indizierte Revaskularisationsmaßnahmen ohne Nutzen für den Patienten abzuwenden zu können. Trotz Klasse IA Empfehlung der ESC ist die Implementierung der FFR-Index-Methode im klinischen Alltag aber unzureichend. IFR als leichter anzuwendende, kostengünstigere und für den Patienten weniger belastende Methode ist der FFR-Messung als gleichrangig anzusehen und kann als potentiell neuer Standard zu einer besseren Umsetzung und häufigeren leitliniengerechten Anwendung der funktionellen Beurteilung von Koronarstenosierungen in der Klinik führen. Bei indizierter PCI ermöglichen innovative Stenttechnologien bei gleicher Effektivität verglichen zu einem Standard-DES eine schnellere Stent-Einheilung mit verkürzter DAPT-Dauer und niedrigerem Blutungsrisiko. Das an mehr als 2500 Patienten prospektiv durchgeführte PF-SES Register belegt den Nutzen und Vorteil dieses polymerfreien Stents im unselektierten klinischen Alltag. Bei Hochrisikopulationen ist der PF-SES dem unbeschichteten BMS überlegen.

description: We present here the final results of the Hubble Space Telescope (HST) Key Project to measure the Hubble constant. We summarize our method, the results, and the uncertainties, tabulate our revised distances, and give the implications of these results for cosmology. Our results are based on a Cepheid calibration of several secondary distance methods applied over the range of about 60–400 Mpc. The analysis presented here benefits from a number of recent improvements and refinements, including (1) a larger LMC Cepheid sample to define the fiducial period-luminosity (PL) relations, (2) a more recent HST Wide Field and Planetary Camera 2 (WFPC2) photometric calibration, (3) a correction for Cepheid metallicity, and (4) a correction for incompleteness bias in the observed Cepheid PL samples. We adopt a distance modulus to the LMC (relative to which the more distant galaxies are measured) of μ0 = 18.50 ± 0.10 mag, or 50 kpc. New, revised distances are given for the 18 spiral galaxies for which Cepheids have been discovered as part of the Key Project, as well as for 13 additional galaxies with published Cepheid data. The new calibration results in a Cepheid distance to NGC 4258 in better agreement with the maser distance to this galaxy. Based on these revised Cepheid distances, we find values (in km s-1 Mpc-1) of H0 = 71 ± 2 ± 6 (systematic) (Type Ia supernovae), H0 = 71 ± 3 ± 7 (Tully-Fisher relation), H0 = 70 ± 5 ± 6 (surface brightness fluctuations), H0 = 72 ± 9 ± 7 (Type II supernovae), and H0 = 82 ± 6 ± 9 (fundamental plane). We combine these results for the different methods with three different weighting schemes, and find good agreement and consistency with H0 = 72 ± 8 km s-1 Mpc-1. Finally, we compare these results with other, global methods for measuring H0.

description: Recent advances in next-generation sequencing and other omics technologies capable to map cell fate provide increasing evidence on the crucial role of intra-tumor heterogeneity (ITH) for cancer progression. The different facets of ITH, from genomic to microenvironmental heterogeneity and the hierarchical cellular architecture originating from the cancer stem cell compartment, contribute to the range of tumor phenotypes. Decoding these complex data resulting from the analysis of tumor tissue complexity poses a challenge for developing novel therapeutic strategies that can counteract tumor evolution and cellular plasticity. To achieve this aim, the development of in vitro and in vivo cancer models that resemble the complexity of ITH is crucial in understanding the interplay of cells and their (micro)environment and, consequently, in testing the efficacy of new targeted treatments and novel strategies of tailoring combinations of treatments to the individual composition of the tumor. This challenging approach may be an important cornerstone in overcoming the development of pharmaco-resistances during multiple lines of treatment. In this paper, we report the latest advances in patient-derived 3D (PD3D) cell cultures and patient-derived tumor xenografts (PDX) as in vitro and in vivo models that can retain the genetic and phenotypic heterogeneity of the tumor tissue.

Les maniféstations du mythe orphique dans l'oeuvre romanesque de Gabrielle Poulin
Creators: name: Lacourcière, Sheila
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2003
Subjects: subject: Literature, Canadian (French).

description: Originaire de Saint-Prosper-de-Beauce au Québec, Gabrielle Poulin vit et écrit à Ottawa depuis 1971. Poète et essayiste, elle a aussi publié six romans, soit Cogne la caboche (1979), Un cri trop grand (1980), Les Mensonges d'Isabelle (1983), La Couronne d'oubli, (1990), Le Livre de déraison (1994) et Qu'est-ce qui passe ici si tard? (1998). L'ensemble de ces romans présente une remarquable quête d'identité des protagonistes qui sont des femmes de tout âge et de toute condition sociale. Cette quête s'effectue dans et par l'écriture, au moyen d'une descente symbolique aux enfers, suivie d'une remontée libératrice. Pour représenter le parcours de ces personnages, Gabrielle Poulin, reprend et réactualise le mythe d'Orphée afin de réécrire cette légende du point de vue féminin. L'art est au coeur du mythe d'Orphée. Au cours de la descente aux enfers de ce héros, la musique de sa lyre et le charme de sa voix lui permettent de voyager sans préjudice dans le monde souterrain. À l'image d'Orphée, c'est par la magie de l'écriture que les protagonistes féminins de Gabrielle Poulin peuvent cheminer dans la mort. Comme pour Orphée, leur ascendance sur les "monstres" provient de l'Art et, comme pour lui, c'est dans le pouvoir créateur que ces femmes cherchent le salut. C'est en nous appuyant sur la méthode de la mythocritique telle qu'élaborée par Gilbert Durand, que nous avons repéré et étudié le mythe d'Orphée et ses maniféstations dans les romans de Gabrielle Poulin. L'oeuvre romanesque de cette écrivaine foisonne d'images. Pour les étudier à fond nous avons adopté la classification d'images mise au point par Gilbert Durand dans Les Structures anthropologiques de l'imaginaire. De plus, les écrits de Mircea Eliade et de Gaston Bachelard nous ont offert un appui précieux. Gabrielle Poulin vit et écrit dans une société et a une époque ou la femme cherche a prendre la parole pour elle-meme. En transformant et en récrivant le mythe d'Orphée, elle accorde à ses personnages le droit de s'affirmer comme sujets autonomes. Ainsi que le démontre notre thèse, il est possible de répondre par l'affirmative à la question que se pose Rachel dans Cogne la caboche: "Peut se ressusciter sof memos?"

Making themselves at home: Strategies of self-representation in pioneer women's autobiographies

Year: 2009

description: This dissertation explores narrative strategies of self-identity in autobiographies by six pioneering women writers, each of whom lost what has traditionally been woman's place: her home. The accounts of emigration, expatriation, and exile by Anna Brownwell Jameson, Catharine Parr Traill, Susanna Moodie, Ada Cambridge, Isak Dinesen, and Alyse Simpson illustrate the implications of this loss, as each woman struggled to recover a sense both of home and of grounded identity. The writings span more than a hundred years, from the 1830s to the 1950s, and tell of lives lived in locations as different as Canada, Australia, and British East Africa (now Kenya), places that variously proved to be confining and/or liberating. By narrating the ways in which identity adapts to and is transformed by a new environment, these texts provide access to the construction and alteration of the self in relation to place. This study probes this process by using the concept of place, rather than the more conventional one of time, as the dominant category of analysis. My readings are both intertextual and interdisciplinary: they rely on theorizing by sociologists and psychologists concerned with the relationship between place and identity, studies on the same subject by literary scholars, and formulations by women's autobiography theorists. My investigation reveals, among other discoveries, that the gender-specific aspects of the process of adaptation persistently centre on the notion of homecoming and that they are articulated with reference to the figure of the mother.

Automated acoustic monitoring of ecosystems
Creators: name: Sethi, Sarab Singh
Publisher: name: Imperial College London
Year: 2020

description: Natural habitats are being impacted by human pressures at an alarming rate. Monitoring these ecosystem-level changes often requires labour-intensive surveys that are unable to detect rapid or unanticipated environmental changes. In this thesis, we explore how recording and analysing the sounds of an environment provides a tractable solution to scalable, fully automated ecological monitoring. First, we tackle the problem of autonomous data collection, and develop a device which is able to continuously collect and remotely transmit data from field sites over long time-periods. We then move to the automated analysis of eco-acoustic data, and exploit a learned acoustic feature embedding to achieve accurate monitoring of ecosystem health across multiple spatial and temporal scales. We demonstrate that an unsupervised approach using the same acoustic feature space allows automatic identification of anomalous sounds, including hallmarks of illegal activity such as gunshots and chainsaws. Functional real-time ecological monitoring requires significant computational infrastructure, and we detail the open-source design and implementation of SAFE Acoustics, an eco-acoustic monitoring network in the tropical rainforests of Borneo. Within the ecosystems we study, species movement and behaviour are constrained by habitat structure and connectivity. However, investigating how topology influences a complex network’s behaviour is not a challenge unique to ecology. We investigate the link between structure and function in a model system, the mouse brain, and find that inter-regional axonal connectivity is closely related to the intrinsic dynamics of individual brain areas. Similar studies inspecting the dynamics of data from large-scale ecological monitoring networks may provide a fruitful avenue for further explorations.

description: The limitations of the first-generation everolimus-eluting coronary bioresorbable vascular scaffolds (BVS) have been demonstrated in several randomized controlled trials. Little data are available regarding the outcomes of patients receiving hybrid stenting with both BVS and drug-eluting stents (DES). Of 3144 patients prospectively enrolled in the GABI-Registry, 435 (age 62 ± 10, 19% females, 970 lesions) received at least one BVS and one metal stent (hybrid group). These patients were compared with the remaining 2709 (3308 lesions) who received BVS-only. Patients who had received hybrid stenting had more frequently a history of cardiovascular disease and revascularization (p < 0.05), had less frequently single-vessel disease (p < 0.0001), and the lesions treated in these patients were longer (p < 0.0001) and more frequently complex. Accordingly, the incidence of periprocedural myocardial infarction (p < 0.05) and that of cardiovascular death, target vessel and lesion failure and any PCI at 24 months was lower in the BVS-only group (all p < 0.05). The 24-months rate of definite and probable scaffold thrombosis was 2.7% in the hybrid group and 2.8% in the BVS-only group, that of stent thrombosis in the hybrid group was 1.86%. In multivariable analysis, only implantation in bifurcation lesions emerged as a predictor of device thrombosis, while the device type was not associated with this outcome (p = 0.21). The higher incidence of events in patients receiving hybrid stenting reflects the higher complexity of the lesions in these patients; in patients treated with a hybrid strategy, the type of device implanted did not influence patients´ outcomes.

description: Background Especially in the current crisis of the COVID-19 pandemic and the lockdown it entailed, technology became crucial. Machines need to be able to interpret and represent human behavior, to improve human interaction with technology. This holds for all domains but even more so for the domain of student behavior in relation to education and psychological well-being. Methods This work presents the theoretical framework of a psychologically driven computing ontology, CCOnto, describing situation-based human behavior in relation to psychological states and traits. In this manuscript, we use and apply CCOnto as a theoretical and formal description system to categorize psychological factors that influence student behavior during the COVID-19 situation. By doing so, we show the added value of ontologies, i.e., their ability to automatically organize information from unstructured human data by identifying and categorizing relevant psychological concepts. Results The already existing CCOnto was modified to automatically categorize university students’ state and trait markers related to different aspects of student behavior, including learning, worrying, health, and socially based on psychological theorizing and psychological data conceptualization. Discussion The paper discusses the potential advantages of using ontologies for describing and modeling psychological research questions. The handling of dataset completion, unification, and its explanation by means of Artificial Intelligence and Machine Learning models is also discussed.

A parallel low-complexity MIMO detection algorithm using QR decomposition and Alamouti space-time code
Creators: name: Arar, Maher
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2010
Subjects: subject: Engineering, Electronics and Electrical.

description: In this thesis we present a parallel N x N MIMO detection algorithm that is suitable for implementation on multi-core low-power processors. This algorithm has multiple versions which, depending on the SNR and target FER, allows for the complexity, performance and power consumption to be traded off on a packet-by-packet basis. The proposed hybrid algorithm essentially consists of coding the transmit symbols in pairs using the Alamouti space-time block code. At the receiver, one or multiple QR decompositions are performed in parallel after which alternate successive interference cancellation, Alamouti decoding and coherent combining are performed. Iterative detection can also be performed should better error performance be required. Despite the use of the capacity-lossy Alamouti code we show that the outage capacity and FER performance of the proposed algorithm at practical SNR levels below 20dB are comparable to, or sometimes outperform, those offered by spatial multiplexing algorithms such as MMSE-VBLAST. Furthermore, we show that our algorithm is more robust than MMSE-VBLAST in the presence of channel imperfections such as spatial correlation and channel estimation errors, two commonly encountered imperfections in practice. We also show that the complexity of our algorithm is equivalent to that of a lower complexity version of MMSE-VBLAST. Through FER comparisons with other well-known hybrid algorithms we also show that our algorithm achieves similar or better performance at a much lower complexity. The features offered by the proposed algorithm that is: parallel architecture, good FER/capacity performance, robustness against channel imperfections make it an ideal candidate for use in 4G and beyond-4G wireless standards.

description: We present the results of near-infrared observations of extragalactic Cepheids made with the Near-Infrared Camera and Multi-Object Spectrometer on board the Hubble Space Telescope (HST). The variables are located in the galaxies IC 1613, IC 4182, M31, M81, M101, NGC 925, NGC 1365, NGC 2090, NGC 3198, NGC 3621, NGC 4496A, and NGC 4536. All fields were observed in the F160W bandpass; additional images were obtained in the F110W and F205W filters. Photometry was performed using the DAOPHOT II/ALLSTAR package. Self-consistent distance moduli and color excesses were obtained by fitting period-luminosity relations in the H, I, and V bands. Our results support the assumption of a standard reddening law adopted by the HST Key Project on the Extragalactic Distance Scale. A companion paper will determine true distance moduli and explore the effects of metallicity on the Cepheid distance scale.

description: Recent behavioral and neuroimaging studies have suggested multisensory processing deficits in patients with schizophrenia (SCZ). Thus far, the neural mechanisms underlying these deficits are not well understood. Previous studies with unisensory stimulation have shown altered neural oscillations in SCZ. As such, altered oscillations could contribute to aberrant multisensory processing in this patient group. To test this assumption, we conducted an electroencephalography (EEG) study in 15 SCZ and 15 control participants in whom we examined neural oscillations and event-related potentials (ERPs) in the sound-induced flash illusion (SIFI). In the SIFI multiple auditory stimuli that are presented alongside a single visual stimulus can induce the illusory percept of multiple visual stimuli. In SCZ and control participants we compared ERPs and neural oscillations between trials that induced an illusion and trials that did not induce an illusion. On the behavioral level, SCZ (55.7%) and control participants (55.4%) did not significantly differ in illusion rates. The analysis of ERPs revealed diminished amplitudes and altered multisensory processing in SCZ compared to controls around 135 ms after stimulus onset. Moreover, the analysis of neural oscillations revealed altered 25–35 Hz power after 100 to 150 ms over occipital scalp for SCZ compared to controls. Our findings extend previous observations of aberrant neural oscillations in unisensory perception paradigms. They suggest that altered ERPs and altered occipital beta/gamma band power reflect aberrant multisensory processing in SCZ.

Reliable machine learning for medical imaging data through automated quality control and data harmonization.
Creators: name: Robinson, Robert
Publisher: name: Imperial College London

description: In medical image analysis pipelines, Machine Learning (ML) is increasingly employed to process images and to derive clinically relevant biomarkers and quantitative measures. Results of these analyses are used to inform clinical decision-making from diagnosis to treatment planning. It is imperative that ML models work reliably, and their results are adequately scrutinized to avoid introducing bias or inaccuracy into downstream tasks. Image segmentation is a key component of many medical image analysis pipeline. For a segmentor to be reliable, it must be possible to identify instances when it has failed. This work presents an extensive validation of an approach for automated Quality Control (QC) of Cardiac Magnetic Resonance Imaging (CMR) segmentations using a reverse testing strategy, which is modified from Reverse Classification Accuracy (RCA) [164]. The method is evaluated on data from the UKBB imaging study, demonstrating its effectiveness at large scale in the absence of Ground Truth (GT). It achieves over 95% accuracy classifying segmentation quality using Dice Similarity Coefficient (DSC). It may be desirable to obtain an immediate assessment of segmentation quality in high throughput pipelines, in pharmaceutical trials, or in the clinic to inform operators when acquired images yield poor quality analysis results. This study presents a method for real-time automated QC using Deep Learning (DL)-based frameworks which directly predict DSCs and proxy RCA scores, achieving MAE = 0.03 and MAE = 0.14 respectively. A model may fail because it is evaluated on data drawn from a different distribution to that on which it was trained, as with scans acquired from different sites. This work introduces and evaluates an unpaired, unsupervised method for Domain Adaptation (DA) on multi-site neuroimaging data, aiming to mitigate the degradation in model performance due to Domain Shift (DS) caused by population and acquisition changes. Over 20% performance is recovered in a classification task when applying constrained appearance and spatial transformations with Image and Spatial Transformer Networks (ISTNs).

Re-conceptualizing the practice of enterprise architecture implementation
Creators: name: Dale, Mark
Publisher: name: Swinburne
Year: 2024

description: My research into enterprise architecture implementation is motivated by the concern that organizations have difficulty in implementing large-scale information technology projects. Enterprise architecture implementation failure represents a significant financial and reputational loss for organizations and is potentially related to the challenges that enterprise architects face in aligning their interpretations of what is important in an enterprise architecture implementation with the interpretations of business and technology stakeholders. The contribution of this research is that it makes suggestions for improving the implementation practices of enterprise architects and the outcome of enterprise architecture implementation initiatives.

description: Introduction: The present study sought to address core issues in the association between personality and the putative disordered use of Facebook. First, to redress the issue of generalisation from samples solely recruited from Facebook, we sought to explore personality differences between users and non-users of Facebook. Second, we aimed to investigate associations between personality and Facebook Use Disorder. The present study contributes a novel perspective to extant research on this topic by moving beyond the broad Big Five of personality, to explore possible relationships between Facebook use and sub-facets of the Big Five; all analyses were additionally controlled for confounding effects of demographic variables. Methods: 3,835 (n = 2,366 males) participants completed socio-demographic variables, the Big Five Inventory and stated their user status on Facebook (i.e. user versus non-user). Facebook-users also completed a Facebook Use Disorder scale assessing addictive tendencies towards Facebook use. Results: Facebook users reported higher levels of extraversion and lower levels of conscientiousness compared to non-users. Tendencies towards Facebook Use Disorder correlated negatively with conscientiousness and positively with neuroticism in both males and females. Conclusions: The present results indicate that research samples drawn from Facebook users may be biased with regard to personality (extraversion, conscientiousness). Moreover, certain personality traits – conscientiousness and neuroticism – which may influence the tendency towards Facebook Use Disorder are discussed.

Substituent effects on the geminal coupling constant in an allylic methylene group.
Creators: name: Raby, Bruce F.
Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: Chemistry, Organic.

description: A series-of substituted methyl 1-methylcyclohex-3-ene-1-carboxylates of the general formula have been synthesized and the proton magnetic resonance spectra measured. The ring protons were extensively coupled to each other and gave complex spectra. The 3, 5, 5'-trideutero analogues have also been synthesized. The geminal coupling constant JAB, was obtained from the AB pattern produced by the magnetically non-equivalent protons in the allylic methylene group. JAB has been found to depend on the nature of the substituent R. A Hammett correlation between JAB and sigma P, the Hammett substituent constant, had a slope or rho value of -2.9. Resonance effects were shown to be much more predominant than field effects.* Long-range coupling over four bonds has been measured between the allylic proton at C2 and the homoallylic proton at C6. The low field proton of each AB group has been tentatively assigned as being cis to the carbomethoxy group. The low field proton of the allylic methylene group showed a larger S. C. S. than the high field proton. Since the low field proton is predominantly in the pseudoequatorial position, this result is opposite to that predicted by a hyperconjugative type of interaction. The chemical shift of the olefinic proton of each compound has been found to obey the additivity scheme of Sternhell and co-workers. *Please refer to dissertation for diagram.

description: Für die Genotypisierung werden gegenwärtig häufig PCR-gestützte Techniken benutzt, die kurze, sogenannte charakteristische beziehungsweise diagnostische Sequenzen nachweisen. Mit diesen Techniken kann der Phänotyp regelmäßig nicht korrekt vorhergesagt werden, wenn sporadische nicht-funktionale Allele angetroffen werden. Die Häufigkeit solcher sporadischer aberranter Allele und ihre dadurch bedingte Bedeutung für die Genotypisierung waren für kein Gen beim Menschen unter niedrigem Selektionsdruck bekannt. In der vorliegenden Arbeit wurde die Frequenz der sehr seltenen Bombay (0h)-Blutgruppe (Genotyp hh sese) in einer systematischen Suche unter mehr als 600.000 Blutspendern in Baden-Württemberg bestimmt. Die Ergebnisse dieser Studie zusammen mit molekularbiologischen Untersuchungen wurden ausgewertet, um die Populationsfrequenz nicht-funktionaler Allele am Beispiel des Gens zu bestimmen, das für die alpha(1,2)Fukosyltransferase kodiert (FUT1 oder H). Sieben unterschiedliche h-Allele wurden in fünf unverwandten Individuen gefunden. Die nachgewiesenen h-Allele unterschieden sich bei allen untersuchten Probanden. Drei der Probanden waren homozygot für ihr privates Allel. Es wurde kein prävalentes h Allel nachgewiesen. Im einzelnen wurden eine frame shift- und fünf missense-Mutationen gefunden, die wahrscheinlich die Null-Phänotypen verursachten. Die kodierende Sequenz eines h Allels war identisch mit der Sequenz des funktionalen H Allels. Der mittlere Konsanguinitätskoeffizient alpha war 0,00116. Die Frequenz der nicht-funktionalen Allele im FUT1-Gen wurde mit 1:367 in einer großen deutschen Population berechnet (95 Prozent-Konfidenzintervall: 1:185 - 1:824). Der Bombay (0h)-Phänotyp wird in der weißen Bevölkerung durch diverse, sporadische nicht-funktionale Allele verursacht. Es gibt kein prävalentes h-Allel. Unser Ansatz erlaubte zum ersten Mal eine direkte Kalkulation des Koeffizienten alpha für eine Population ohne Berücksichtigung von Verwandtschaftsverhältnissen. Unter der Annahme ähnlicher Häufigkeiten von nicht-funktionalen Allelen in anderen Glykosyltransferase-Genen, wie zum Beispiel in den Genen der AB0-Blutgruppe, können die gegenwärtigen Genotypisierungsstrategien Fehlerraten mit einer Häufigkeit von einem in ungefähr 300 Individuen der Blutgruppe 0 aufweisen. Sporadische neutrale Allele können ebenso ein erhebliches Problem für die populationsweite Genotypisierung vieler krankheitsassoziierter Gene darstellen.
