description: Species identification using matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) data strongly relies on reference libraries to differentiate species. Because comprehensive reference libraries, especially for metazoans, are rare, we explored the accuracy of unsupervised diversity estimations of communities using MALDI-TOF MS data in the absence of reference libraries to provide a method for future application in ecological research. To discover the best analysis strategy providing high congruence with true community structures, we carried out a simulation with more than 30,000 analyses using different combinations of data transformations, dimensionality reductions, and cluster algorithms. Species profile, Hellinger, and presence/absence transformations were applied to raw data and dimensions were reduced using principal component analysis (PCA), t-distributed stochastic neighbor embedding, and uniform manifold approximation and projection. To estimate biodiversity, data were clustered making use of partitioning around medoids, model-based clustering, and K-means clustering. The analyses were carried out on published mass spectrometry data of harpacticoid copepods. Most successful combinations (Hellinger transformation + PCA or raw data + partitioning around medoids) returned good values even for difficult species distributions containing numerous singleton species. Nevertheless, errors occurred most frequently because of such singleton taxa. Hence, replicative sampling in wide sampling areas for analysis is emphasized to increase the minimum number of specimens per species, thus reducing putative sources of errors. Our results demonstrate that MALDI-TOF MS data can be used to accurately estimate the biodiversity of unknown communities using unsupervised learning methods. The provided approach allows the biodiversity comparison of sampled regions for which no reference libraries are available. Hence, especially data on groups which demand a time-consuming identification or are highly abundant can be analyzed within short working time, accelerating ecological studies.

description: Overfitting is one of the fundamental challenges when training convolutional neural networks and is usually identified by a diverging training and test loss. The underlying dynamics of how the flow of activations induce overfitting is however poorly understood. In this study we introduce a perplexity-based sparsity definition to derive and visualise layer-wise activation measures. These novel explainable AI strategies reveal a surprising relationship between activation sparsity and overfitting, namely an increase in sparsity in the feature extraction layers shortly before the test loss starts rising. This tendency is preserved across network architectures and reguralisation strategies so that our measures can be used as a reliable indicator for overfitting while decoupling the network's generalisation capabilities from its loss-based definition. Moreover, our differentiable sparsity formulation can be used to explicitly penalise the emergence of sparsity during training so that the impact of reduced sparsity on overfitting can be studied in real-time. Applying this penalty and analysing activation sparsity for well known regularisers and in common network architectures supports the hypothesis that reduced activation sparsity can effectively improve the generalisation and classification performance. In line with other recent work on this topic, our methods reveal novel insights into the contradicting concepts of activation sparsity and network capacity by demonstrating that dense activations can enable discriminative feature learning while efficiently exploiting the capacity of deep models without suffering from overfitting, even when trained excessively.

description: Methane (CH4) production in the ocean surface mixed layer is a widespread but still largely unexplained phenomenon. In this context marine algae have recently been described as a possible source of CH4 in surface waters. In the present study we investigated the effects of temperature and light intensity (including daylength) on CH4 formation from three widespread marine algal species Emiliania huxleyi, Phaeocystis globosa, and Chrysochromulina sp. Rates of E. huxleyi increased by 210% when temperature increased in a range from 10°C to 21.5°C, while a further increase in temperature (up to 23.8°C) showed reduction of CH4 production rates. Our results clearly showed that CH4 formation of E. huxleyi is controlled by light: When light intensity increased from 30 to 2,670 μmol m−2 s−1, CH4 emission rates increased continuously by almost 1 order of magnitude and was more than 1 order of magnitude higher when the daylength (light period) was extended from 6/18 hr light-dark cycle to continuous light. Furthermore, light intensity is also an important factor controlling CH4 emissions of Chrysochromulina sp. and P. globosa and could therefore be a species-independent regulator of phytoplankton CH4 production. Based on our results, we might conclude that extensive blooms of E. huxleyi could act as a main regional source of CH4 in surface water, since blooming of E. huxleyi is related to the seasonal increase in both light and temperature, which also stimulate CH4 production. Under typical global change scenarios, E. huxleyi will increase its CH4 production in the future.

description: In July 2007, the blazar 3C 454.3 underwent a flare in the optical, reaching R~13 on July 19. Then the optical flux decreased by one magnitude, being R~14 when the source was detected by the gamma-ray satellite AGILE, that observed the source on July 24-30. At the same time, the Swift satellite performed a series of snapshots. We can construct the simultaneous spectral energy distribution using optical, UV, X-ray and gamma-ray data. These shows that an increased gamma-ray flux is accompanied by a weaker optical/X-ray flux with respect to the flare observed in the Spring 2005 by INTEGRAL and Swift. This confirms earlier suggestions about the behaviour of the jet of 3C 454.3.

A Multi-Resolution Weak Lensing Mass Reconstruction Method

Year: 2008

description: Motivated by the limitations encountered with the commonly used direct reconstruction techniques of producing mass maps, we have developed a multi-resolution maximum-likelihood reconstruction method for producing two dimensional mass maps using weak gravitational lensing data. To utilize all the shear information, we employ an iterative inverse method with a properly selected regularization coefficient which fits the deflection potential at the position of each galaxy. By producing mass maps with multiple resolutions in the different parts of the observed field, we can achieve a comparable level of signal to noise by increasing the resolution in regions of higher distortions or regions with an over-density of background galaxies. In addition, we are able to better study the sub-structure of the massive clusters at a resolution which is not attainable in the rest of the observed field. We apply our method to the simulated data and to a four square degree field obtained by the Deep Lens Survey.

Anschließend werden mehrere Neutrino-Observablen mit Hilfe einer einfachen und gut motivierten Klasse von Flavor-Modellen vorhergesagt, wodurch ein schmaler bevorzugter Bereich für die absolute Neutrino-Massenskala resultiert, der mit zukünftigen Experimenten erforscht werden kann. Schließlich werden neue Grenzen an flavor-verletzende Kopplungen von Axionen an leichte Quarks aus der Beobachtung der Supernova SN1987A bestimmt, die den Energieverlust durch leichte Teilchen, die in \( \Lambda \)-Hyperon-Zerfällen und -Bremsstrahlung produziert werden, beschränkt.

description: We review what can (and cannot) be learned if dark matter is detected in one or more experiments, emphasizing the importance of combining LHC data with direct, astrophysical and cosmological probes of dark matter. We briefly review the conventional picture of a thermally produced WIMP relic density and its connection with theories of electroweak symmetry breaking. We then discuss both experimental and theoretical reasons why one might generically expect this picture to fail. If this is the case, we argue that a combined effort bringing together all types of data -- combined with explicitly constructed theoretical models -- will be the only way to achieve a complete understanding of the dark matter in our universe and become confident that any candidate actually provides the relic density.

description: We experimentally investigate nonlinear couplings between vibrational modes of strings of cold ions stored in linear ion traps. The nonlinearity is caused by the ions' Coulomb interaction and gives rise to a Kerr-type interaction Hamiltonian H = n_r*n_s, where n_r,n_s are phonon number operators of two interacting vibrational modes. We precisely measure the resulting oscillation frequency shift and observe a collapse and revival of the contrast in a Ramsey experiment. Implications for ion trap experiments aiming at high-fidelity quantum gate operations are discussed.

description: Medical dialogue generation aims to provide automatic and accurate responses to assist physicians to obtain diagnosis and treatment suggestions in an efficient manner. In medical dialogues two key characteristics are relevant for response generation: patient states (such as symptoms, medication) and physician actions (such as diagnosis, treatments). In medical scenarios large-scale human annotations are usually not available, due to the high costs and privacy requirements. Hence, current approaches to medical dialogue generation typically do not explicitly account for patient states and physician actions, and focus on implicit representation instead. We propose an end-to-end variational reasoning approach to medical dialogue generation. To be able to deal with a limited amount of labeled data, we introduce both patient state and physician action as latent variables with categorical priors for explicit patient state tracking and physician policy learning, respectively. We propose a variational Bayesian generative approach to approximate posterior distributions over patient states and physician actions. We use an efficient stochastic gradient variational Bayes estimator to optimize the derived evidence lower bound, where a 2-stage collapsed inference method is proposed to reduce the bias during model training. A physician policy network composed of an action-classifier and two reasoning detectors is proposed for augmented reasoning ability. We conduct experiments on three datasets collected from medical platforms. Our experimental results show that the proposed method outperforms state-of-the-art baselines in terms of objective and subjective evaluation metrics. Our experiments also indicate that our proposed semi-supervised reasoning method achieves a comparable performance as state-of-the-art fully supervised learning baselines for physician policy learning.

description: An important tool for statistical research are moment inequalities for sums of independent random vectors. Nemirovski and coworkers (1983, 2000) derived one particular type of such inequalities: For certain Banach spaces $(\B,\|\cdot\|)$ there exists a constant $K = K(\B,\|\cdot\|)$ such that for arbitrary independent and centered random vectors $X_1, X_2, ..., X_n \in \B$, their sum $S_n$ satisfies the inequality $ E \|S_n \|^2 \le K \sum_{i=1}^n E \|X_i\|^2$. We present and compare three different approaches to obtain such inequalities: Nemirovski's results are based on deterministic inequalities for norms. Another possible vehicle are type and cotype inequalities, a tool from probability theory on Banach spaces. Finally, we use a truncation argument plus Bernstein's inequality to obtain another version of the moment inequality above. Interestingly, all three approaches have their own merits.

description: The classical trajectories for FLRW universe with varying speed of light are obtained for the cases in which the cosmological constant depends or not depend on the velocity of light. The theory is then quantized and the corresponding WDW equation is solved. It is shown that the method of causal interpretation of Bohm can be applied successfully to the theory. Finally the Bohmian trajectories are obtained and compared with the classical ones.
Entanglement and non-locality in quantum protocols with identical particles

description: We study the role of entanglement and non-locality in quantum protocols that make use of systems of identical particles. Unlike in the case of distinguishable particles, the notions of entanglement and non-locality for systems whose constituents cannot be distinguished and singly addressed are still debated. We clarify why the only approach that avoids incongruities and paradoxes is the one based on the second quantization formalism whereby it is the entanglement of the modes that can be populated by the particles what really matters and not the particles themselves. Indeed, by means of a metrological and of a teleportation protocol, we show that inconsistencies arise in formulations that force entanglement and non-locality to be properties of the identical particles rather than of the modes they can occupy. The reason resides in the fact that orthogonal modes can always be addressed while identical particles can not.
Simultaneous and sequential processing, reading, and neurological maturation of Native Indian (Tsimshian) children
Creators: name: Williams, David George
Publisher: name: University of British Columbia
Year: 2010

description: This study was designed to investigate the relationship between the developmental trends for Simultaneous and Sequential Information Processing and the developmental trends for Reading and Neurological Maturation, and if these trends are influenced by cultural/experiential background. Differences in Kaufman Assessment Battery for Children: Mental Processing trends (for Simultaneous and Sequential Processing) between North Coast B.C. Native Indian (Tsimshian) children and Non-Native children, as well as differences in the developmental trends for reading decoding and comprehension (B.C. QUIET: Word Identification and Passage Comprehension subtests, and K-ABC: Reading Understanding subtest), and neurological maturation (Grip Strength Test) were examined with a sample of 225 children ages 8-12. Since cultural/experiential background was proposed as a primary influence on the dependent variables, two samples of Native Indian children were used: one from isolated north coast B.C. villages and the other from the north coast city of Prince Rupert. The Non-Native sample also came from Prince Rupert. Canonical analysis revealed significant relationships between Ethnicity and Sirnlultaneous and Sequential Processing, the Simultaneous and Processing Subtests, Reading, and Neurological Maturation variables. Differences between the two Native groups were more significant than differences between the Non-Native and either Native group. There was no observable "Native Indian pattern" of Simultaneous and Sequential Processing. What was observable was a different maturational rate for the Village-Native group on Information Processing, Reading, and Neurological Maturation. These differences are interpreted as differences in maturational rate rather than permanent deficits in function. An anticipated lag in the development of sequential processing skills by the Native Indian groups was not evident. Both modes of processing were available to each group at every age level. The Non-Native group came closest to displaying a lag in sequential processing skills. It was concluded that Simultaneous and Sequential Information Processing, Reading, and Neurological Maturation displayed similar developmental trends which were primarily determined by Age and cultural/experiential background.

description: With its remarkable double-S shape, IC 4634 is an archetype of point-symmetric planetary nebulae (PN). In this paper, we present a detailed study of this PN using archival HST WFPC2 and ground-based narrow-band images to investigate its morphology, and long-slit spectroscopic observations to determine its kinematics and to derive its physical conditions and excitation. The data reveal new structural components, including a distant string of knots distributed along an arc-like feature 40"-60" from the center of the nebula, a skin of enhanced [O III]/H-alpha ratio enveloping the inner shell and the double-S feature, and a triple-shell structure. The spatio-kinematical study also finds an equatorial component of the main nebula that is kinematically independent from the bright inner S-shaped arc. We have investigated in detail the bow shock-like features in IC 4634 and found that their morphological, kinematical and emission properties are consistent with the interaction of a collimated outflow with surrounding material. Indeed, the morphology and kinematics of some of these features can be interpreted using a 3D numerical simulation of a collimated outflow precessing at a moderate, time-dependent velocity. Apparently, IC 4634 has experienced several episodes of point-symmetric ejections oriented at different directions with the outer S-shaped feature being related to an earlier point-symmetric ejection and the outermost arc-like string of knots being the relic of an even much earlier point-symmetric ejection. There is tantalizing evidence that the action of these collimated outflows has also taken part in the shaping of the innermost shell and inner S-shaped arc of IC 4634.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: In this note we reconsider Sen's entropy function analysis for 5D supergravity actions containing Chern-Simons terms. The apparent lack of gauge invariance is usually tackled via a 4D reduction. Here we motivate how a systematic 5D procedure also works. In doing so, it becomes important to identify the correct 5D charges. In particular, we perform explicit calculations for the black ring and 5D black hole. In the black ring analysis, we find Chern-Simons induced spectral flow shifts emerging out of Sen's formalism. We find that the entropy function nevertheless remains gauge invariant and the resulting electric charges are identified as Page charges. For the black hole too, 5D gauge invariance is confirmed. Our 5D analysis enables us to fix a mismatch that arose in the electric charges of Goldstein and Jena's 4D-reduced calculation. Finally we provide an interpretation for the e^0 - p^0 exchange in the entropy function as an interpolation between black hole and black ring geometries in Taub-NUT.

description: The fully coupled climate model AWI-CM is run on two different ocean grids to investigate the impact of horizontal resolution on the simulated Arctic Ocean circulation, and Arctic-Atlantic as well as Arctic Pacific linkages. The ocean-sea ice component runs on an unstructured grid, the low-resolution version has a grid size of about 24 km in the Arctic Ocean, while the high-resolution grid has a grid size of about 4.5 km resolution in the Arctic Ocean. The high-resolution grid has already been tested in uncoupled runs with CORE-II forcing, where is showed improved representation of Atlantic Water circulation and associated heat content in the Arctic.  Now, the impact of the higher resolution will be assessed in the coupled set-up and on longer time scales (150 years).

description: In this paper, we study the perturbative aspects of a "B-twisted" two-dimensional $(0,2)$ heterotic sigma model on a holomorphic gauge bundle $\mathcal E$ over a complex, hermitian manifold $X$. We show that the model can be naturally described in terms of the mathematical theory of ``Chiral Differential Operators". In particular, the physical anomalies of the sigma model can be reinterpreted as an obstruction to a global definition of the associated sheaf of vertex superalgebras derived from the free conformal field theory describing the model locally on $X$. In addition, one can also obtain a novel understanding of the sigma model one-loop beta function solely in terms of holomorphic data. At the $(2,2)$ locus, one can describe the resulting half-twisted variant of the topological B-model in terms of a $\it{mirror}$ "Chiral de Rham complex" (or CDR) defined by Malikov et al. in \cite{GMS1}. Via mirror symmetry, one can also derive various conjectural expressions relating the sheaf cohomology of the mirror CDR to that of the original CDR on pairs of Calabi-Yau mirror manifolds. An analysis of the half-twisted model on a non-Kähler group manifold with torsion also allows one to draw conclusions about the corresponding sheaves of CDR (and its mirror) that are consistent with mathematically established results by Ben-Bassat in \cite{ben} on the mirror symmetry of generalised complex manifolds. These conclusions therefore suggest an interesting relevance of the sheaf of CDR in the recent study of generalised mirror symmetry.

If the Wigner matrices are Gaussian, Mingo and Speicher's notion of second order freeness gives a universal rule, in terms of marginal first and second order distribution. We adapt and reformulate this notion for operator-valued random variables in a second order probability space. The Wigner matrices are assumed to be permutation invariant with null pseudo variance and the deterministic matrices to satisfy a restrictive property

An evaluation of three computer based test interpretation systems for the WISC-R
Creators: name: Otter, Murray
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to evaluate three computer-based test interpretation systems for the Wechsler Intelligence Scale for Children- Revised (1974). The systems were evaluated first in terms of whether they were considered acceptable in terms of recently proposed guidelines for computerized interpretation and secondly, the degree to which they were considered adequate and useful in clinical practice. A rating scale incorporating the above criteria was designed for this study by the author. The results indicate a general failure of the systems evaluated, to meet acceptable levels of adequacy in terms of either set of criteria. Possible explanations of the poor ratings of these systems, limitations of the study and implications for further research are raised in the Discussion. The study ends with some conclusions regarding computerized interpretation systems for the WISC-R.

description: Gerbillus campestris is a widely distributed small rodent that lives in various habitats in North Africa and can be a potential agricultural pest. We conducted a biogeographic study of this species with an integrative approach using mor-phometric data from body and craniomandibular distances and molecular genetic data from the cytochrome b gene of the mitochondrial DNA. We collected 96 individuals in six localities from central, northern and eastern Morocco. Data from 18 morphological characters were used in multivariate statistical analyses and molecular data were analysed using maxi-mum likelihood and median-joining networks. Our analyses confirmed the high morphological variability in this species and allowed to discriminate four groups containing the studied populations. We found that a few craniomandibular measu-rements had the highest contribution in the differences between populations, and that this variability reflected a spatial and environmental differentiation. In the genetic analyses, we placed our six populations and six individuals from four other countries in nine previously identified phylogenetic lineages in this species, and we also added a tenth lineage. Limited gene flow, isolation by distance and biogeographic barriers were further explored to explain this genetic structuration. We also jointly examined morphometric and genetic variability and found that the morphological groups were congruent with the genetic lineages and the geographic distribution. A better knowledge of the phenotypic plasticity and genetic diversity of this gerbil can be used to comprehend the micro-evolutionary processes in other small mammals in North Africa.
Adittional levels between Landau bands due to vacancies in graphene: towards a defect engineering

description: We describe the effects of vacancies on the electronic properties of a graphene sheet in the presence of a perpendicular magnetic field: from a single defect to an organized vacancy lattice. An isolated vacancy is the minimal possible inner edge, showing an antidotlike behaviour, which results in an extra level between consecutive Landau levels. Two close vacancies may couple to each other, forming a vacancy molecule tuned by the magnetic field. We show that a vacancy lattice introduce an extra band in between Landau levels with localization properties that could lead to extra Hall resistance plateaus.

description: The first use of the stretched exponential function to describe the time evolution of a non-equilibrium quantity is usually credited to Rudolph Kohlrausch (1809-1858), who in 1854 applied it to the discharge of a capacitor. Attention is drawn to a set of pioneering works on the Kohlrausch function, one of which published 101 years ago, and that are not mentioned by Cardona, Chamberlin, and Marx in Ann. Phys. (Leipzig) 16, 842 (2007).

Towards a New Standard Model for Black Hole Accretion

description: We briefly review recent developments in black hole accretion disk theory, emphasizing the vital role played by magnetohydrodynamic (MHD) stresses in transporting angular momentum. The apparent universality of accretion-related outflow phenomena is a strong indicator that large-scale MHD torques facilitate vertical transport of angular momentum. This leads to an enhanced overall rate of angular momentum transport and allows accretion of matter to proceed at an interesting rate. Furthermore, we argue that when vertical transport is important, the radial structure of the accretion disk is modified at small radii and this affects the disk emission spectrum. We present a simple model demonstrating how energetic, magnetically-driven outflows modify the emergent disk emission spectrum with respect to that predicted by standard accretion disk theory. A comparison of the predicted spectra against observations of quasar spectral energy distributions suggests that mass accretion rates inferred using the standard disk model may severely underestimate their true values.

An observational study of the developmental sequence of one-to-one correspondence in young children's counting and reading
Creators: name: La Pierre, Jo Ann
Publisher: name: University of British Columbia
Year: 2010

description: This study investigated one-to-one correspondence as a basic cognitive function of young children, by examining its application to children's counting and to their recognizing words in beginning reading. Over the course of nine months, data was gathered on a total of forty children in three settings: preschool (3.5-4.5 years), ECS (4.5-5.5 years) and grade one (5.5-7 years). As the purpose of the study was to generate hypotheses, rather than test them, an observational, rather than experimental, design was used. Children's ability to match spoken number words to objects when counting was compared to their ability to match spoken words with their written counterpart in an attempt to discover an underlying learning pattern based on one-to-one correspondence. One-to-one correspondence in reading and the child's concept of word were explored through the use of the child's own words in a key vocabulary approach based on the model of Sylvia Ashton-Warner. The responses of three children, referred to as "key incident children," were described in fuller detail as they highlighted certain points of the study. Three major hypotheses were proposed. The first suggests a developmental continuum in a child's counting that may have a parallel continum in her reading. The second hypothesis proposes that a certain level of one-to-one correspondence in counting may be a prerequisite for beginning reading and the third deals with the possible predictive nature of the relationship. The practical value of a better understanding of one-to-one correspondence in children for teachers of both normal and special needs children is discussed. Limitations of the study and suggestions for further research are included.
