PROPAGATION OF DYSREGULATION ACROSS GENE EXPRESSION LAYERS IN 7Q11.23 CNV ASSOCIATED DEVELOPMENTAL DISORDERS
Creators: name: D'AGOSTINO, GIUSEPPE ALESSANDRO
Publisher: name: Universit� degli Studi di Milano
Year: 2017

description: Williams-Beuren Syndrome (WBS) and 7q11.23 microduplication syndrome (7dup), two multi-systemic developmental disorders, arise from symmetrical copy number variations of the same region on chromosome 7q. In WBS patients this region is deleted, whereas it is duplicated in 7dup individuals. These syndromes display a striking combination of shared and opposite clinical manifestations at the level of neuro-cognitive, craniofacial and cardiovascular features, thus pointing to a remarkable dosage-sensitive effect of a small group of genes on the development and maintenance of complex traits such as sociality, language and facial morphology. We derived a large cohort of induced pluripotent stem cells (iPSCs) from samples with WBS, 7dup and from healthy controls, and we demonstrated that, already at the pluripotent state, the transcriptome is dysregulated in pathways that map onto disease-related features. Moreover, these pathways were selectively dysregulated in differentiated lineages, thus demonstrating an anticipatory power of the pluripotent state. Building on these results, we expanded the view on the dysregulation in pluripotency by measuring three layers of gene expression: transcriptome, translatome and proteome. We mapped the propagation of differences across layers by integrating ribosome profiling and SWATH-MS proteomics, and we probed the extent to which a translation initiation factor included in the CNV, EIF4H, was responsible for the regulation of translation. We found that each layer of gene expression has its own differentially expressed genes, whose degrees of propagation can change between layers. Moreover, differentially expressed genes can cluster by different ways of propagation when they are compared to the levels of EIF4H.
From Anecdote to Evidence: The Relationship Between Personality and Need for Cognition of Developers

description: There is considerable anecdotal evidence suggesting that software engineers enjoy engaging in solving puzzles and other cognitive efforts. A tendency to engage in and enjoy effortful thinking is referred to as a person's 'need for cognition.' In this article we study the relationship between software engineers' personality traits and their need for cognition. Through a large-scale sample study of 483 respondents we collected data to capture the six 'bright' personality traits of the HEXACO model of personality, and three `dark' personality traits. Data were analyzed using several methods including a multiple Bayesian linear regression analysis. The results indicate that ca. 33% of variation in developers' need for cognition can be explained by personality traits. The Bayesian analysis suggests four traits to be of particular interest in predicting need for cognition: openness to experience, conscientiousness, honesty-humility, and emotionality. Further, we also find that need for cognition of software engineers is, on average, higher than in the general population, based on a comparison with prior studies. Given the importance of human factors for software engineers' performance in general, and problem solving skills in particular, our findings suggest several implications for recruitment, working behavior, and teaming.

The suitability of continuous laminated veneer lumber production to some Canadian wood species
Creators: name: Afolayan, Ademola Adeniyi
Publisher: name: University of British Columbia
Year: 2010

description: Laminated veneer lumber was made by gluing six layers of 1/4-inch veneer assembled with grain directions parallel and all the tight veneer surfaces outward. A specially modified phenol-formaldehyde plywood resin was used. Shear strength and wood failure of specimens tested dry, and after accelerated aging, were used to evaluate bond quality. Limited samples of broadleaf maple laminated veneer lumber were used to demonstrate that, with central glueline just reaching 240°F before opening the press, adequate bonds were formed. These were not significantly different from those produced with a central glueline temperature reaching 300°F. Tests of specimens from small panels of broadleaf maple, black cottonwood, and sugar maple showed that a gluespread of at least 42.5 pounds per thousand square feet of single glueline (42.5 lb/MSGL) was required. At this spread, a central glueline temperature of 240°F and platen temperature of 350°F, adequate bond quality was produced at platen pressures of 200 psi, 100 psi and 275 psi for broadleaf maple, black cottonwood and sugar maple, respectively. Based on the press schedules developed with the small panels, black cottonwood, sugar maple, and white spruce, continuous laminated veneer lumber boards were manufactured, using the process described by Bohlen in 1972. Only the white spruce boards produced adequate bonds. Those of black cottonwood and sugar maple failed due to dry-out of glue adjacent to the platens. Although suitable pressing conditions were worked out for single-pressed boards, irrespective of wood species, the glue would need further modification for the hardwoods studied to be used for continuously produced laminated veneer lumber.

description: Using small-angle neutron scattering, we demonstrate that the complex magnetic domain patterns at the surface of Nd2Fe14B, revealed by quantitative Kerr and Faraday microscopy, propagate into the bulk and exhibit structural features with dimensions down to 6 nm, the domain wall thickness. The observed fractal nature of the domain structures provides an explanation for the anomalous increase in the bulk magnetization of Nd2Fe14B below the spin-reorientation transition. These measurements open up a rich playground for studies of fractal structures in highly anisotropic magnetic systems.

description: We report on our second campaign to search for old nova shells around cataclysmic variables (CVs). Our aim was to test the theory that nova eruptions cause cycles in the mass transfer rates of CVs. These mass transfer cycles change the behaviour of CVs during their inter-eruption periods. We examined H-alpha images of 47 objects and found no new shells around any of the targets. Combining our latest results with our previous campaign (Sahman et al. 2015), and the searches by Schmidtobreick et al. (2015) and Pagnotta & Zurek (2016), we estimate that the nova-like phase of the mass transfer cycle lasts approximately 3,000 years.

Forest sampling on two occasions with partial replacement of sample units
Creators: name: See, Thomas Elton
Publisher: name: University of British Columbia
Year: 2010

description: Forest sampling is conducted to determine current conditions and trends of change. When current conditions are estimated, most of the commonly used sampling designs specify the spatial distribution of sample units. When estimation of change is desired, several schemes may be employed. Some are combined with current condition inventories; some are independent. The former are relatively imprecise; the latter relatively expensive. A system of temporal distribution of sample units, sampling on successive occasions with partial replacement of sample units, has been developed for simultaneous estimation of current conditions and trends. As the emphasis is on time, rather than area, this system operates with conventional sampling designs to increase their efficiency. This study investigated the theory of sampling with partial replacement to establish the validity of the claims of increased efficiency in comparison with conventional systems. Three cases are examined, through example, for estimation of mean volume per acre and growth in volume per acre. Sample sizes and costs are developed for the situation of simple random sampling of both finite and infinite populations. The comparisons are favorable to the proposed system. The possibilities of using this system with two recent developments in cruising techniques are explored. Finally, the applicability of this system to British Columbia forest surveys is examined. A case is made for transition of the existing provincial system to sampling with partial replacement.

On the Dynamics of Hopfield Neural Networks on Unit Quaternions

Year: 2021
Subjects: subject: Neural and Evolutionary Computing (cs.NE)

description: In this paper, we first address the dynamics of the elegant multi-valued quaternionic Hopfield neural network (MV-QHNN) proposed by Minemoto and collaborators. Contrary to what was expected, we show that the MV-QHNN, as well as one of its variation, does not always come to rest at an equilibrium state under the usual conditions. In fact, we provide simple examples in which the network yields a periodic sequence of quaternionic state vectors. Afterward, we turn our attention to the continuous-valued quaternionic Hopfield neural network (CV-QHNN), which can be derived from the MV-QHNN by means of a limit process. The CV-QHNN can be implemented more easily than the MV-QHNN model. Furthermore, the asynchronous CV-QHNN always settles down into an equilibrium state under the usual conditions. Theoretical issues are all illustrated by examples in this paper.
Trends in Adult and Continuing Education in Germany

description: This contribution summarizes the most important trends in adult education in Germany as they were elaborated in a secondary analytic research project of the DIE (Deutsches Institut für Erwachsenenbildung – German Institute for Adult Education) in 2007. According to the study, participation in continuing education in Germany is increasing after long years of decrease, even though, overall, financing of adult education has been further reduced. Cooperation as well as competition between continuing education institutions has increased. Course offers have become shorter, counselling and information have more significant roles than in the past, and those employed in adult education, especially teaching staff, have a higher level of qualifications than before. Adult education policy in Germany has varying aims as a result of the federal structure of the country. Incentives for vocational and workplace training predominate however.

description: The aim of this paper is to investigate mental model theory, introduced by Philip Johnson-Laird to describe a ground level of logical cognition, concerning propositional logic and the fragment of predicate logic covering syllogisms. In order to appreciate the philosophical implications of the theory, the nature of mental models and the resulting picture of human rationality are discussed, by considering recent developments of the theory as well. We examine the issues concerning deductive competence and its computational implementation and argue that the notion of mental model calls for embodied cognitive architecture out of which ‘reasoners’ can construct models. Finally, we highlight the need of updating the concept of mental model through embodied cognition, with reference to spatial and perceptual abilities in reasoning.

Different from the previous models, in this analysis the resonance decay widths are constrained to the values given by the Particle Data Group (PDG). The result indicates that constraining these parameters to the PDG values could dramatically change the conclusion of the important resonances in this reaction found in the previous studies.

description: We present results on the QCD equation of state, obtained with two different improved dynamical staggered fermion actions and almost physical quark masses. Lattice cut-off effects are discussed in detail as results for three different lattice spacings are available now, i.e. results have been obtained on lattices with temporal extent of $N_τ=4,6$ and 8. Furthermore we discuss the Taylor expansion approach to non-zero baryon chemical potential by means of an expansion of the pressure. We use the expansion coefficients to calculate various fluctuations and correlations among hadronic charges. We find that the correlations reproduce the qualitative behavior of the resonance gas model below $T_c$ and start to agree with the free gas predictions for $T\gsim 1.5T_c$.

description: Traditionally, ground-based spectrophotometric observations probing transiting exoplanet atmospheres have employed a linear map between comparison and target star light curves (e.g. via differential spectrophotometry) to correct for systematics contaminating the transit signal. As an alternative to this conventional method, we introduce a new Gaussian Processes (GP) regression-based method to analyse ground-based spectrophotometric data. Our new method allows for a generalised non-linear mapping between the target transit light curves and the time series used to detrend them. This represents an improvement compared to previous studies because the target and comparison star fluxes are affected by different telluric and instrumental systematics, which are complex and non-linear. We apply our method to six Gemini/GMOS transits of the warm (T$_{\rm eq}$ = 990 K) Neptune HAT-P-26b. We obtain on average $\sim$20 % better transit depth precision and residual scatter on the white light curve compared to the conventional method when using the comparison star light curve as a GP regressor and $\sim$20% worse when explicitly not using the comparison star. Ultimately, with only a cost of 30% precision on the transmission spectra, our method overcomes the necessity of using comparison stars in the instrument field of view, which has been one of the limiting factors for ground-based observations of the atmospheres of exoplanets transiting bright stars. We obtain a flat transmission spectrum for HAT-P-26b in the range of 490-900 nm that can be explained by the presence of a grey opacity cloud deck, and indications of transit timing variations, both of which are consistent with previous measurements.

description: Context. The origin, evolution, and ultimate fate of magnetic cataclysmic variables are poorly understood. It is largely the nature of the magnetic fields in these systems that leads to this poor understanding. Fundamental properties, such as the field strength and the axis alignment, are unknown in a majority of these systems. Aims. We undertake to put all the previous circular polarization measurements into context and systematically survey intermediate polars for signs of circular polarization, hence to get an indication of their true magnetic field strengths and try to understand the evolution of magnetic cataclysmic variables. Methods. We used the TurPol instrument at the Nordic Optical Telescope to obtain simultaneous UBVRI photo-polarimetric observations of a set of intermediate polars, during the epoch 2006 July 31 - August 2. Results. Of this set of eight systems two (1RXS J213344.1+510725 and 1RXS J173021.5-055933) were found to show significant levels of circular polarization, varying with spin phase. Five others (V2306 Cyg, AO Psc, DQ Her, FO Aqr, and V1223 Sgr) show some evidence for circular polarization and variation of this with spin phase, whilst AE Aqr shows little evidence for polarized emission. We also report the first simultaneous UBVRI photometry of the newly identified intermediate polar 1RXS J173021.5-055933. Conclusions. Circular polarization may be ubiquitous in intermediate polars, albeit at a low level of one or two percent or less. It is stronger at longer wavelengths in the visible spectrum. Our results lend further support to the possible link between the presence of soft X-ray components and the detectability of circular polarization in intermediate polars.

description: Discovered in 1909 the Evershed effect represents strong mass outflows in sunspot penumbra, where the magnetic field of sunspots is filamentary and almost horizontal. These flows play important role in sunspots and have been studied in detail using large ground-based and space telescopes, but the basic understanding of its mechanism is still missing. We present results of realistic numerical simulations of the Sun's subsurface dynamics, and argue that the key mechanism of this effect is in non-linear magnetoconvection that has properties of traveling waves in the presence of strong, highly inclined magnetic field. The simulations reproduce many observed features of the Evershed effect, including the high-speed "Evershed clouds", the filamentary structure of the flows, and the non-stationary quasi-periodic behavior. The results provide a synergy of previous theoretical models and lead to an interesting prediction of a large-scale organization of the outflows.

We focus on the characteristics of silicate at 10 and 20 microns, analyzing the influence of composition and grain size on peak strengths and spectral shapes. We present the first results of the Cosmic Dust Laboratory, a dedicated facility at the Universidad Diego Portales equipped with a VERTEX 80v vacuum Fourier transform infrared spectrometer. Through milling and sieving samples, we obtained different ranges of particle sizes to study the effect of grain size on the intensity and shape of the spectrum. The resulting spectral library can be compared with astronomical data of protoplanetary disks, debris disks, and even white dwarf disks obtained with instruments such as MIRI on board the James Webb Space Telescope and MATISSE on the Very Large Telescope Interferometer. We also present mass absorption coefficient values, which can be used for radiative transfer modeling of astronomical observations. This study aims to improve dust opacities for astronomical applications, with a focus on circumstellar disks.

description: In this paper, we investigate the entanglement degrees of pseudoscalar meson states via quantum algebra Y(su(3)). By making use of transition effect of generators J of Y(su(3)), we construct various transition operators in terms of J of Y(su(3)), and act them on eta-pion-eta mixing meson state. The entanglement degrees of both the initial state and final state are calculated with the help of entropy theory. The diagrams of entanglement degrees are presented. Our result shows that a state with desired entanglement degree can be achieved by acting proper chosen transition operator on an initial state. This sheds new light on the connect among quantum information, particle physics and Yangian algebra.

description: We study the possibility of ferromagnetism in metals. The metal is described by two hybridized bands one of which includes Hubbard correlation whereas the other is uncorrelated. We parametrize the ratio of the band widths and their centers as well. The original Hamiltonian is transformed in an effective and simpler one. Only one site retains the full correlation (U) while in the others acts as an internal field, the self-energy, in the framework of an alloy analogy approximation. This field, in turn, is self-consistently determined by imposing the translational invariance of the problem. For several total electronic occupation numbers (n_{total}) we compare the spin dependent free energies with the corresponding paramagnetic ones. We present several results pointing out the mechanism by which the self-consistency introduces a sort of constraints, for given values of band width and band shift .

description: NASA's Kepler mission observed background regions across its field of view for more than three consecutive years using custom designed super apertures (EXBA masks). Since these apertures were designed to capture a region of the sky rather than single targets, the Kepler Science Data Processing pipeline produced Target Pixel Files, but did not produce light curves for the sources within these background regions. In this work we produce light curves for $9,327$ sources observed in the EXBA masks. These light curves are generated using aperture photometry estimated from the instrument's Pixel Response Function (PRF) profile computed from Kepler's full-frame images. The PRF models enable the creation of apertures that follow the characteristic shapes of the PSF in the image and the computation of flux completeness and contamination metrics. The light curves are available at MAST as a High Level Science Product (kbonus-apexba). Alongside this dataset, we present kepler-apertures, a Python library to compute PRF models and use them to perform aperture photometry on Kepler-like data. Using light curves from the EXBA masks we found an exoplanet candidate around Gaia EDR3 2077240046296834304 consistent with a large planet companion with a $0.81 R_J$ radius. Additionally, we report a catalog of 69 eclipsing binaries. We encourage the community to exploit this new dataset to perform in depth time domain analysis, such as eclipsing binaries demographic and others.

description: The field of neural networks has seen significant advances in recent years with the development of deep and convolutional neural networks. Although many of the current works address real-valued models, recent studies reveal that neural networks with hypercomplex-valued parameters can better capture, generalize, and represent the complexity of multidimensional data. This paper explores the quaternion-valued convolutional neural network application for a pattern recognition task from medicine, namely, the diagnosis of acute lymphoblastic leukemia. Precisely, we compare the performance of real-valued and quaternion-valued convolutional neural networks to classify lymphoblasts from the peripheral blood smear microscopic images. The quaternion-valued convolutional neural network achieved better or similar performance than its corresponding real-valued network but using only 34% of its parameters. This result confirms that quaternion algebra allows capturing and extracting information from a color image with fewer parameters.

La famiglia: un progetto pedagogico
Creators: name: Certini, Rossella
Publisher: name: Studi sulla Formazione
Year: 2014

description: The essay briefly reconstructs the complex origin of the concept of family. Rereading the classic literature on the subject (by Rousseau, to Engels, to Gramsci to the most recent authors such as Max Horkheimer or Chiara Saraceno) you may notice that the historical context and the structure of society have always influenced the structure of the family. It was passed by the singular (family) to the plural (families) and this implies the general transformation of the systems of life today. Speaking of project-family means to reflect on these changes with planning purposes, trying to focus on new strategies to enhance and support the needs of families today. One of the most critical aspects of the family institution in Italy is the weakness of social policies in support of it. The essay can be considered as an introductory course to the study on the complex galaxy called family.

Sinestesias: hacia una visión panorámica de la poesía multimedia española actual
Creators: name: Corral Cañas, Celia
Publisher: name: Università degli Studi di Milano
Year: 2014

description: En el panorama de la poesía española actual desde una perspectiva experimental destaca el ámbito de las creaciones a partir de dispositivos tecnológicos. Entre los diversos acercamientos al arte verbal digital adquiere especial relevancia la poesía multimedia, en la cual se logra una transcendencia del texto en favor de una convergencia de los componentes visual y auditivo. Como consecuencia de este hibridismo, se produce un efecto multisensorial que devuelve a la poesía a su sentido original e implica un alcance más amplio en el tipo de recepción. Por consiguiente, este tipo de creaciones se desenvuelve de los límites de la palabra y se orienta, desde la sinestesia como rasgo identitario de su naturaleza, hacia la idea de «obra de arte total».

The effects of lensing by local structures on the dipole of radio source counts

description: Our peculiar motion in a homogeneous and isotropic universe imprints a dipole in the cosmic microwave background (CMB) temperature field and similarly imprints a dipole in the distribution of extragalactic radio sources on the sky. Each of these effects have been measured, however each of these measurements give different results for the velocity of our motion through the Universe: the radio dipole measurements finds the speed of our motion to be around three times larger than that of the CMB. Here we show the effects of the previously unconstrained lensing dipole, whereby necessarily local structures (required for large angular lensing scales) will distort the distribution of radio sources on the sky. We find that the inclusion of these effects does not reduce the tension between the CMB and radio source dipole measurements however without their inclusion future extragalactic number counts could lead to incorrect inferences of our peculiar motion. In addition we can constrain the size of the lensing dipole to be $κ< 3 \cdot 10^{-2}$ at the $2 σ$ level.

description: Helium gas is applied to high-altitude airships or platforms to buoy and sustain them at the desired altitude around 20km from the Earth's surface. Helium gas is supplied to the balloon of the platform constantly or regularly to make up for the natural gas loss. Helium gas compressors are necessary for that purpose. However, to develop such helium compressors for high-altitude platforms, there are some technical difficulties to meet the severe environmental conditions other than those of the near-surface. We designed a helium compressor model and tested it in simulated environmental and operating conditions at the desired altitude. Our system uses airfoil bearings instead of conventional ball bearings using lubricating oils or magnetic bearings. By adopting a unique design for airfoil bearings, our system has met the requirements of the platform application.
