description: This study presents PRISM, a probabilistic simplex component analysis approach to identifying the vertices of a data-circumscribing simplex from data. The problem has a rich variety of applications, the most notable being hyperspectral unmixing in remote sensing and non-negative matrix factorization in machine learning. PRISM uses a simple probabilistic model, namely, uniform simplex data distribution and additive Gaussian noise, and it carries out inference by maximum likelihood. The inference model is sound in the sense that the vertices are provably identifiable under some assumptions, and it suggests that PRISM can be effective in combating noise when the number of data points is large. PRISM has strong, but hidden, relationships with simplex volume minimization, a powerful geometric approach for the same problem. We study these fundamental aspects, and we also consider algorithmic schemes based on importance sampling and variational inference. In particular, the variational inference scheme is shown to resemble a matrix factorization problem with a special regularizer, which draws an interesting connection to the matrix factorization approach. Numerical results are provided to demonstrate the potential of PRISM.

description: A pandemia causada pelo novo coronavírus (SARS-CoV-2) demandou maior celeridade na produção científica e se tornou tema de grande circulação dentre o e fora da academia. Muitas pesquisas sobre a COVID-19 têm sido disponibilizadas na forma de comunicação rápida e em versões preliminares (preprints) que não foram validadas formalmente por outros cientistas. Com o objetivo de compreender o papel do preprint na comunicação científica, seu impacto e disseminação nas redes sociais, a pesquisa analisa dados bibliométricos de citação e altmétricos de menções online dos preprints sobre o COVID-19 disponibilizados no repositório medRxix em 2020. Ao todo foram identificados 7.640 preprints sobre COVID-19, que oferecerm 27.616 citações e 703.654 menções online. O conjunto de preprints analisado obtive 38,5% de cobertura em citações e 53% de menções em fontes da web social, com destaque para o Twitter com mais menções (97,29%) seguido das agências de notícias (2,33%). Mesmo em consonância com o movimento da Ciência Aberta em defesa da abertura e democratização do conhecimento, os preprints não foram revisados por pares, aumentando as chances de controvérsias em sua metodologia ou conteúdo, ou ainda as possiblidades de disputas na produção de narrativas sob interesses políticos e econômicos, especialmente quando compartilhados na arena das mídias sociais.

description: Kaon photo-production process on $^{12}$C has been studied by measuring neutral kaons in a photon energy range of 0.8$-$1.1 GeV. Neutral kaons were identified by the invariant mass constructed from two charged pions emitted in the $K^{0}_{S}\toπ^{+}π^{-}$ decay channel. The differential cross sections as well as the integrated ones in the threshold photon energy region were obtained. The obtained momentum spectra were compared with a Spectator model calculation using elementary amplitudes of kaon photo-production given by recent isobar models. Present result provides, for the first time, the information on $n(γ,K^{0})Λ$ reaction which is expected to play an important role to construct models for strangeness production by the electromagnetic interaction. Experimental results show that cross section of $^{12}{\rm C}(γ,K^0)$ is of the same order to that of $^{12}{\rm C}(γ,K^+)$ and suggest that slightly backward $K^0$ angular distribution is favored in the $γn\to K^0Λ$ process.

Για αυτόν το λόγο πραγματοποιήθηκε χαρτογράφηση φθορισμού ακτίνων Χ (XRF-mapping) στις περιοχές όπου έλαβε χώρα η έγχυση των νανοσωματιδίων προκειμένου να οπτικοποιηθεί η κατανομή αυτών. Συγκεκριμένα, συγκρίθηκαν οι κατανομές των επιμέρους στοιχείων, από τα οποία αποτελούνται τα νανοσωματίδια, για όλα τα μελετώμενα δείγματα. Παράλληλα, πραγματοποιήθηκε καταγραφή και ανάλυση των φασμάτων XANES (λεπτής υφής ακμής απορρόφησης ακτίνων Χ) στις ακμές Κ του βαναδίου και L3 του γαδολινίου και του ευρωπίου για τα νανοσωματίδια πριν και μετά την έγχυσή τους στον ιστό. Η φασματοσκοπία XANES υπέδειξε σημαντικές πληροφορίες για την δομή των νανοσωματιδίων. Ως βιολογικοί ιστοί χρησιμοποιήθηκαν ιστοί αφτιών ποντικών.
description: The present Thesis focuses on the study of the distribution and structure of the colloidal solution of nanoparticles Gd0.6Eu0.4VO4 (with dimensions of 30 nm) when it is injected into biological tissues. For this reason, X-ray fluorescence mapping (XRF-mapping) was applied in the areas where the nanoparticles were injected in order to visualize their distribution. More specifically, the distributions of the individual elements, which constitute the nanoparticles, were compared for all the samples studied. At the same time, XANES (X-ray absorption near edge structure) spectra were recorded and analyzed at the K-edges of vanadium and L3 of gadolinium and europium for the nanoparticles before and after the injection into the tissue. XANES spectroscopy yielded important information about the structure of the nanoparticles. Tissues from the ears of three mice were used as biological tissues.

description: We present supersymmetric, curved space, quantum mechanical models based on deformations of a parabolic subalgebra of osp(2p+2|Q). The dynamics are governed by a spinning particle action whose internal coordinates are Lorentz vectors labeled by the fundamental representation of osp(2p|Q). The states of the theory are tensors or spinor-tensors on the curved background while conserved charges correspond to the various differential geometry operators acting on these. The Hamiltonian generalizes Lichnerowicz's wave/Laplace operator. It is central, and the models are supersymmetric whenever the background is a symmetric space, although there is an osp(2p|Q) superalgebra for any curved background. The lowest purely bosonic example (2p,Q)=(2,0) corresponds to a deformed Jacobi group and describes Lichnerowicz's original algebra of constant curvature, differential geometric operators acting on symmetric tensors. The case (2p,Q)=(0,1) is simply the {\cal N}=1 superparticle whose supercharge amounts to the Dirac operator acting on spinors. The (2p,Q)=(0,2) model is the {\cal N}=2 supersymmetric quantum mechanics corresponding to differential forms. (This latter pair of models are supersymmetric on any Riemannian background.) When Q is odd, the models apply to spinor-tensors. The (2p,Q)=(2,1) model is distinguished by admitting a central Lichnerowicz-Dirac operator when the background is constant curvature. The new supersymmetric models are novel in that the Hamiltonian is not just a square of super charges, but rather a sum of commutators of supercharges and commutators of bosonic charges. These models and superalgebras are a very useful tool for any study involving high rank tensors and spinors on manifolds.

description: The study of epidemiological systems has generated deep interest in exploring the dynamical complexity of common infectious diseases driven by seasonally varying contact rates. Mathematical modeling and field observations have shown that, under seasonal variation, the incidence rates of some endemic infectious diseases fluctuate dramatically and the dynamics is often characterized by chaotic oscillations in the absence of specific vaccination programs. In fact, the existence of chaotic behavior has been precisely stated in the literature as a noticeable feature in the dynamics of the classical Susceptible-Infected-Recovered (SIR) seasonally forced epidemic model. However, in the context of epidemiology, chaos is often regarded as an undesirable phenomenon associated with the unpredictability of infectious diseases. As a consequence, the problem of converting chaotic motions into regular motions becomes particularly relevant. In this article, we consider the phase control technique applied to the seasonally forced SIR epidemic model to suppress chaos. Interestingly, this method of controlling chaos takes on a clear meaning as a weak perturbation on a seasonal vaccination strategy. Numerical simulations show that the phase difference between the two periodic forces - contact rate and vaccination - plays a very important role in controlling chaos.

description: The purpose of this thesis is to build a program in MATLAB to study the efficiency and stability of algorithms for finding a source inside a sphere. At first, the thesis is introduced with reports on the specific problem. We start with the theoretical study of the problem and the motivations of the research. Reference is also made to applications of problem solving in various sciences. Then, we describe the theory on which the construction of the program is based on. In particular, we begin with the mathematical formulation of the problem and its division into two problems, the static and the acoustic. Next, we mention the theory of the static problem for a point source and a point dipole, as well as the theory for the acoustic problem. Finally, the effect of noise on both previous cases was studied. More specifically, with the use of the program, we have added noise to various examples for both the static and the acoustic problem to see what affects and to what extent
Lord Cromer as Orientalist and social engineering in Egypt, 1882-1907
Creators: name: Kernaghan, Jennifer
Publisher: name: University of British Columbia
Year: 2008

description: This thesis examines Lord Cromer's aspirations for developing the 'native mind’ in occupied Egypt, 1882 - 1907. From March 1877 to May 1879, and again from September 1879 until April 1880, Evelyn Baring 1 served as a financial adviser to the Khedival regime. After spending the spring of 1883 in India on the Viceroy's council as Finance Minister, Lord Cromer returned to Egypt in September 1883. He was appointed Consul General and remained until May, 1907, as the virtual ruler of Egypt. As an Orientalist, Cromer manipulates the Egyptian's 'mind' by representing it in his works. As Consul General, he attempts to manipulate that 'mind' through reforms. Lord Cromer perceives the 'Egyptian mind' as deficient, which he considers to be a formidable obstacle to the 'imperial mission'. It will be seen throughout this thesis that the 'flawed Egyptian mind' is a contributing factor to the extended British Occupation: Britain needs to stay until it is reformed. Cromer writes about the need to reform the ’native mind' in accordance with the British-European 'type'. The 'native mind' has to be 'developed', 'trained' and 'civilized', and the entire 'subject population' has to learn how to 'think'. Cromer sought to construct a new and better 'collective mind' for `the Egyptian'. While this paper is not about developing Egypt, it will be proven that Cromer considered developing 'the Egyptian' tantamount to developing Egypt. 1 William Welch Jr., No Country for a Gentleman: British Rule in Egypt, 1883 - 190ZNew York: Greenwood Press, 1988, p. 19. Baring was created Baron Cromer in 1891and the Earl of Cromer in 1907.

description: Ο σκοπός της διπλωματικής εργασίας είναι διττός. Ο πρώτος στόχος είναι να διαπιστωθεί το πώς συγκροτείται η έννοια «Εαυτός» στο έργο του Marivaux Η Φιλονικία, λαμβάνοντας ως βασική παράμετρο της συγκρότησης αυτής την έννοια «Άλλος». Για την ανάλυση αυτή χρησιμοποιήθηκε μια φαινομενολογική προσέγγιση βασισμένη στους Maurice Merleau-Ponty και Paul Ricoeur. Συγκεκριμένα στα έργα τους Φαινομενολογία της αντίληψης και Ο ίδιος ο εαυτός ως άλλος αντίστοιχα. Μέσα από αυτή τη διαδικασία αναζητήθηκε και ο δεύτερος στόχος, ο οποίος συνίσταται στη διερεύνηση του αν και κατά πόσον η φιλοσοφία μπορεί να λειτουργήσει ως δραματουργία. Ως μέθοδος ανάλυσης ενός θεατρικού κειμένου τόσο σε επίπεδο σύνθεσης, όσο και ως σκηνική πράξη. Ακολουθήθηκε η εξής διαδρομή: Αρχικά παρατίθεται μια επιγραμματική παρουσίαση των σχέσεων μεταξύ θεάτρου και φιλοσοφίας. Ακολουθεί κατόπιν μια γενεαλογία της έννοιας του υποκειμένου στη νεότερη φιλοσοφία και ο ορισμός των αξόνων από το έργο των δύο φιλοσόφων, μέσω των οποίων έγινε η ανάλυση του θεατρικού κειμένου. Κατόπιν έγινε μια σύντομη παρουσίαση του συγγραφέα και του έργου του μέσα στα ιστορικά του συμφραζόμενα. Τέλος ακολούθησε η καθαυτό ανάλυση του κειμένου μέσα από το πρίσμα που ορίστηκε και τα συμπεράσματα επί των δύο στόχων.
description: The purpose of the thesis is twofold. The first goal is to ascertain how the concept of "Self" is constructed in Marivaux's The Dispute, assuming as its basic parameter the concept of "Other". For this analysis a phenomenological approach was used, based on Maurice Merleau-Ponty and Paul Ricoeur, namely on their works Phenomenology of Perception and Oneself as Another respectively. Through this process the second goal was sought, which is to investigate to what extent philosophy can function as dramaturgy. As a method of analyzing a theatrical text in terms of both composition and of the stage. To achieve those goals, a presentation of the relationship between theater and philosophy was outlined at first. This was followed by a genealogy of the term “subject” in modern philosophy. Then the key points from the work of the two philosophers through which the text was analyzed were defined, followed by a brief presentation of Marivaux and his work placed in their historical context. The last part consists of the analysis of the text itself and the final conclusions.

description: In genetic studies of complex diseases, the underlying mode of inheritance is often not known. Thus, the most powerful test or other optimal procedure for one model, e.g. recessive, may be quite inefficient if another model, e.g. dominant, describes the inheritance process. Rather than choose among the procedures that are optimal for a particular model, it is preferable to see a method that has high efficiency across a family of scientifically realistic models. Statisticians well recognize that this situation is analogous to the selection of an estimator of location when the form of the underlying distribution is not known. We review how the concepts and techniques in the efficiency robustness literature that are used to obtain efficiency robust estimators and rank tests can be adapted for the analysis of genetic data. In particular, several statistics have been used to test for a genetic association between a disease and a candidate allele or marker allele from data collected in case-control studies. Each of them is optimal for a specific inheritance model and we describe and compare several robust methods. The most suitable robust test depends somewhat on the range of plausible genetic models. When little is known about the inheritance process, the maximum of the optimal statistics for the extreme models and an intermediate one is usually the preferred choice. Sometimes one can eliminate a mode of inheritance, e.g. from prior studies of family pedigrees one may know whether the disease skips generations or not. If it does, the disease is much more likely to follow a recessive model than a dominant one. In that case, a simpler linear combination of the optimal tests for the extreme models can be a robust choice.

Συγκεκριμένα, αφού παρουσιάσαμε τις διάφορες μορφές της ευγονικής και τα διάφορα νοήματά της ανά τους αιώνες, αναφερθήκαμε στα δύο είδη διακρίσεων των ευγονικών εφαρμογών, την αυταρχική/φιλελεύθερη ευγονική και την θεραπευτική/ενισχυτική ευγονική. Στην συνέχεια, παρουσιάστηκαν αναλυτικά τα είδη των ιατρικών βελτιωτικών κι αναπαραγωγικών τεχνολογιών. Έπειτα, αναφερθήκαμε στις απόψεις των υπερασπιστών των τεχνολογιών της σύγχρονης ευγονικής, τις οποίες και σχολιάσαμε. Ακολούθως, παρουσιάσαμε και σχολιάσαμε τις απόψεις των κριτικών των σύγχρονων γενετικών τεχνολογιών. Τέλος, κάναμε μια αποτίμηση των συμπερασμάτων και των ηθικών προβληματισμών που προκύπτουν από την εφαρμογή των σύγχρονων γενετικών τεχνολογιών.
description: In the present thesis, I am dealing with the moral dimension of the eugenical applications in the reproductive technologies and in the technologies of enhancement. Specifically, after presenting the different forms of the eugenics and the different meanings of the eugenics throughout the centuries, we referred to the two types of distinctions of the eugenics’ applications, the authoritarian/ liberal eugenics and the eugenics for curing reasons/enhancing reasons. Afterwards, we referred to the defenders’ opinions about the contemporary eugenics and then we commented these opinions. Accordingly, we presented and commented the opinions of the critics about the contemporary genetic technologies. In the end, we assessed the conclusions and the ethical concerns that turn up due to the contemporary genetic technologies’ applications.

description: Social media has grown exponentially in a short period, coming to the forefront of communications and online interactions. Despite their rapid growth, social media platforms have been unable to scale to different languages globally and remain inaccessible to many. In this paper, we characterize Koo, a multilingual micro-blogging site that rose in popularity in 2021, as an Indian alternative to Twitter. We collected a dataset of 4.07 million users, 163.12 million follower-following relationships, and their content and activity across 12 languages. We study the user demographic along the lines of language, location, gender, and profession. The prominent presence of Indian languages in the discourse on Koo indicates the platform's success in promoting regional languages. We observe Koo's follower-following network to be much denser than Twitter's, comprising of closely-knit linguistic communities. An N-gram analysis of posts on Koo shows a #KooVsTwitter rhetoric, revealing the debate comparing the two platforms. Our characterization highlights the dynamics of the multilingual social network and its diverse Indian user base.

Uniparental disomy as a cause for congenital malformations and or developmental delay in inherited apparently balanced chromosomal rearrangements
Creators: name: Lopez-Rangel, Elena
Publisher: name: University of British Columbia

description: Chromosomal translocations are said to be balanced if there is no apparent gain or loss of genetic material. Apparently balanced chromosomal rearrangements are usually associated with a normal phenotype [Therman 1986, Daniel 1988]. However the frequency of mental retardation and congenital anomalies appears to be increased among individuals who carry a de novo or an inherited apparently balanced chromosomal rearrangement [Funderburk et. al. 1977, Aymeet. al. 1979, Fryns et. al. 1986, Howard-Peebles and Friedman1986]. Uniparental disomy occurs when both chromosomes in a pair are inherited from one parent instead of one of the chromosomes being inherited from each parent [Searle et. al. 1985, Cattanach et. al.1985, Lyon et. al. 1985]. Uniparental disomy has recently been established as a cause for congenital anomalies and mental retardation in humans [Spence et. al. 1988, Voss et. al. 1989, Nicholls et. al. 1989, Henry et. al. 1991, Knoll et. al. 1989, Wanget. al. 1991, Temple et. al. 1991, Pentao 1992]. In mice, uniparental disomy for any chromosome may be produced by mating animals that carry certain chromosomal rearrangements which alter normal meiotic segregation [Cattanach 1985, Cattanach 1986, Cattanach 1988, Cattanach 1989). We have investigated the possibility that uniparental disomy may cause mental retardation and malformations in carriers of an inherited apparently balanced chromosomal translocation. We studied 7 families in which one or more childen with congenital anomalies and mental retardation have inherited an apparently balanced translocation from a carrier parent. In order to establish the parental origin of the chromosomes, we collected blood from both parents and the affected child. We determined the parental origin of each of the chromosomes involved in the translocations using DNA probes that detect highly polymorphic loci which have been previously mapped to these chromosomes [Nakamura et al. 1987,Lathrop et al. 1988, Nakamura et al. 1988, Boerwinkle et al. 1989,Batanian 1990, Standen et al. 1990, Weber et al. 1991, Zoghbi et al. 1991, Ranum et al. 1991, Scharf et al. 1992, Litt et al. 1992].We were able to rule out uniparental disomy for each of the chromosomes involved in the translocation in every patient except one who had inherited an apparently balanced translocation from a carrier parent and who presented with malformations and/or developmental delay. In one patient uniparental disomy was ruled out for one of the chromosomes in the translocation but the markers was uninformative for the other chromosome. We conclude that uniparental disomy is not a common occurence in carriers of inherited apparently balanced reciprocal translocations who present with congenital anomalies and/or developmental delay.

On the origin of surprisingly cold gas discs in galaxies at high redshift

description: We address the puzzling observational indications for very "cold" galactic discs at redshifts $z \gtrsim 3$, an epoch when discs are expected to be highly perturbed. Using a high-resolution cosmological zoom-in simulation, we identify such a cold disc at $z\sim 3.5$, with a rotation velocity to velocity dispersion ratio of $v_ϕ/σ_r \simeq 5$ for the total gas. It forms as a result of a period of intense accretion of co-planar, co-rotating gas via cold cosmic-web streams. This thin disc survives for $\sim 5$ orbital periods, after which it is disrupted by mergers and counter-rotating streams, longer but consistent with our estimate that a galaxy of this mass ($M_\star\sim10^{10}\mathrm{M_\odot}$) typically survives merger-driven spin flips for $\sim 2-3$ orbital periods. We find that $v_ϕ/σ_r$ is highly sensitive to the tracer used to perform the kinematic analysis. While it is $v_ϕ/σ_r \simeq 3.5$ for atomic HI gas, it is $v_ϕ/σ_r \simeq 8$ for molecular CO and H$_2$. This reflects the confinement of molecular gas to cold, dense clouds that reside near the disc mid-plane, while the atomic gas is spread into a turbulent and more extended thicker disc. The proposed mechanisms is a theoretical proposal that has not been validated yet with proper statistical measurements and it remains unclear whether it occurs frequently enough to explain the multiple discoveries of cold gas disks in high-z galaxies.

description: In cold atom experiments, each image of light refracted and absorbed by an atomic ensemble carries a remarkable amount of information. Numerous imaging techniques including absorption, fluorescence, and phase-contrast are commonly used. Other techniques such as off-resonance defocused imaging (ORDI), where an in-focus image is deconvolved from a defocused image, have been demonstrated but find only niche applications. The ORDI inversion process introduces systematic artifacts because it relies on regularization to account for missing information at some spatial frequencies. In the present work, we extend ORDI to use multiple cameras simultaneously at degrees of defocus, eliminating the need for regularization and its attendant artifacts. We demonstrate this technique by imaging Bose-Einstein condensates, and show that the statistical uncertainties in the measured column density using the multiple-camera off-resonance defocused (MORD) imaging method are competitive with absorption imaging near resonance and phase contrast imaging far from resonance. Experimentally, the MORD method may be incorporated into existing set-ups with minimal additional equipment.

Can we understand exoplanets better if we combine high contrast images and high res spectra using a machine learning pipeline

description: Direct detection methods of exoplanets have the capability to detect wide orbit planets with separations >10AU from its host stars. Direct images contain the star and its planetary companion with the star typically being brighter than the planetary companion by a few orders of magnitude. This is termed the contrast. For lower contrast the planet is easily distinguishable from the star, and the background noise. However, for higher contrasts the brightness of the planet is typically of the same order as the background noise. Finer distinctions in pixel space have been proposed by adding a spectral dimension. This has led to simultaneous imaging and spectrography such that each pixel is accompanied by an individual spectrum forming a spectrum-pixel or 'spaxel'. We have attempted to identify and characterize planetary spectra in each spaxel considering only the spectral dimension using deep learning techniques.

 We define two research goals to this end, a) discriminate between stellar spectrum that has planetary spectrum with a pre-defined contrast b) Extract basic characteristics of the planetary companion in a). In order to achieve this we have used a 1D convolutional neural network (1DCNN) to make distinctions between those spectra with and without a companion. We have also used an additional deep MLP to regress to Teff and logg. We have trained the network with synthetic spectra from BT-Settl-Ames (Allard et al 2012) and the Pickles catalog. Synthetic spectra were generated and were modified with different instrumental spectral resolutions. Additionally, we tested the result for the PDS 70 system (Christaens et al 2019).

 Our findings reveal that the 1DCNN is difficult to train and requires large amount of data but once trained the 1DCNN is very robust and less noise limited than the corresponding cross-correlation technique. The 1DCNN was found to be more reliable with few false positives and higher accuracy. The MLP also has proven difficult to train, but is very accurate in recovering Teff, logg.
