description: Generalmente cuando se presentan las tablas de Operacionalización de Variables y la Matriz de Consistencia en los proyectos de tesis tradicional no existen dificultad; sin embargo, ese no es el caso cuando se opta por el modelo del PLS - SEM. Resulta que los Modelos de Ecuaciones Estructurales con Mínimos Cuadrados Parciales (PLS-SEM por sus siglas), tienen jerarquías que deben ser ubicadas de manera pertinente y lógica. De esto trata el trabajo. Generally, when the Operationalization of Variables and the Consistency Matrix tables are presented in traditional thesis projects, there is no difficulty; however, this is not the case when choosing the PLS - SEM model. It turns out that the Structural Equation Models with Partial Minimum Squares (PLS-SEM), have hierarchies that must be located in a relevant and logical way. This is what work is about.

description: Children with ADHD are at high risk of developing a Reading Disability (RD), although the reasons remain unclear. ADHD-associated impairments, including processing speed, can complicate clinical evaluation for a co-occurring RD diagnosis. We propose a novel metric to (a) assess reading development and (b) provide an alternative method to classifying readers that may aid investigations for etiologies of RD in ADHD. Specifically, as both phonological decoding and word recognition skills are important precursors of reading fluency, we propose a new quantitative method comparing these skills after accounting for variations in perception, motor response, or processing speeds. Forty boys (14 control, 15 ADHD, 11 ADHD/ + RD) completed a lexical decision task testing decoding and another assessing word recognition. Response time data was modeled using a Drift Diffusion approach to estimate the underlying reading skills. Using these reading skill estimates, we calculated a novel Reading Tendency Index and classified participants into three reading groups (Decoders, Balanced Readers, and Sight Readers). The reading and cognitive performance of these groups were consistent with theoretical predictions and subsequently provided external validity for the novel Reading Tendency Index classification. Our findings demonstrate a potential classification tool for readers based on individual’s developed, reading tendencies.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: This study explores the relationship between the self-confidence and content knowledge of undergraduate students in a large enrollment geoscience course following an active-learning think-pair-share (TPS) activity, and whether high confidence necessarily leads to overconfidence. We used a pre-experimental, one group pre-test – post-test design, and an audience response system to record students’ responses to a series of questions covering geoscience concepts and the level of confidence that students had in their answers. During each class session, the students were first asked to engage in one or two TPS activities before responding to a series of questions, focusing on content knowledge and self-confidence. We analyzed the data using exploratory data analysis, boxplots, bar graphs, the Wilcoxon signed-rank test and the Chi-Square test. Results indicate that the content knowledge and self-confidence of students increased after students participated in TPS activities. 55% of students correctly answered the pre-activity question, and 74% correctly answered the post-activity question. The results also reveal that while the TPS activity helped to improve self-confidence from a median of 3 to 4 on a five-point scale, the proportion of responses from students that were overconfident in their abilities decreased from 22% in the pre-activity to 13% in the post-activity.

description: We propose a method for constructing $\texttt{PREPARE}$ circuits for quantum phase estimation of a molecular Hamiltonian in quantum chemistry by using variational optimization of quantum circuits solely on classical computers. The $\texttt{PREPARE}$ circuit generates a quantum state which encodes the coefficients of the terms in the Hamiltonian as probability amplitudes and plays a crucial role in the state-of-the-art efficient implementations of quantum phase estimation. We employ the automatic quantum circuit encoding algorithm [Shirakawa $\textit{et al.}$, arXiv:2112.14524] to construct $\texttt{PREPARE}$ circuits, which requires classical simulations of quantum circuits of $O(\log N)$ qubits with $N$ being the number of qubits of the Hamiltonian. The generated $\texttt{PREPARE}$ circuits do not need any ancillary qubit. We demonstrate our method by investigating the number of $T$-gates of the obtained $\texttt{PREPARE}$ circuits for quantum chemistry Hamiltonians of various molecules, which shows a constant-factor reduction compared to previous approaches that do not use ancillary qubits. Since the number of available logical qubits and $T$ gates will be limited at the early stage of the fault-tolerant quantum computing, the proposed method is particularly of use for performing the quantum phase estimation with such limited capability.

description: Background: The best available evidence regarding non-steroidal anti-inflammatory drug (NSAID)-related gastrointestinal (GI) bleeding comes from randomized controlled trials including patients who use NSAIDs to manage chronic rheumatic diseases; however, patients with varying background profiles commonly take NSAIDs for many other reasons, often without prescription, and such usage has not been well studied. Objectives and Methods: To define the characteristics of patients hospitalized for upper GI bleeding in clinical practice, we conducted a case-control study among patients with endoscopy-proven major upper GI bleeding due to gastroduodenal peptic lesions and control subjects. We used adjusted logistic regression models to estimate bleeding risks. Data analysis was performed using SPSS 22.0. Results: Our analysis included 3,785 cases and 6,540 controls, including 1,270 cases (33.55%) and 834 controls (12.75%) reporting recent use (<30 days) of NSAIDs including high-dose acetylsalicylic acid (ASA). NSAID use was associated with increased risk of upper GI bleeding, with an adjusted relative risk of 4.86 (95% CI, 4.32-5.46). Acute musculoskeletal pain (36.1%), chronic osteoarthritis (13.5%), and headache (13.6%) were the most common reasons for NSAID use. Among cases, only 17.31% took NSAIDs and 6.38% took high dose ASA due to chronic osteoarthritis. Demographic characteristics significantly differed between subjects with chronic vs. acute musculoskeletal pain. Proton pump inhibitor use was significantly higher in patients who used NSAIDs due to with chronic osteoarthritis compared to patients with acute musculoskeletal pain. NSAID (65.15%) or high-dose ASA use (65.83%) preceding upper GI bleeding was most often short-term. In over half of cases (63.62%), the upper GI bleeding event was not preceded by dyspeptic warning symptoms. Conclusions: The majority of patients hospitalized due to NSAID-related upper GI bleeding reported short-term NSAID use for reasons other than chronic rheumatic disease. These findings suggest that current prevention strategies may not reach a wide population of short-term NSAID users

description: Indoor air quality at schools (elementary, primary) has been the subject of many studies; however, there are still relative few data regarding preschool (3- to 5-year-old children) environments. This investigation determined the concentrations of particulate matter (PM)2.5, total volatile organic compounds (TVOC), formaldehyde, carbon monoxide (CO), and ozone (O3) as well as the levels of carbon dioxide (CO2), temperature, and relative humidity (RH) in the indoor and outdoor air of two preschools situated in different geographical regions of Portugal. The indoor concentrations of TVOC, CO, O3, and CO2 were predominantly higher at the end of school day compared to early morning periods. The TVOC and CO2 concentrations were higher indoors than outdoors suggesting predominantly an indoor origin. Outdoor air infiltrations were the major contributing source of CO and O3 to indoor air in both preschools. The concentrations of all pollutants were within the limits defined by national regulations and international organizations, except for TVOC that exceeded 8–12-fold higher than the recommendation of 0.2 mg/m3 proposed by European Commission. The levels of CO2 were below the protective guideline of 2250 mg/m3 (Portuguese legislation); however, the observed ranges exceeded the Portuguese margin of tolerance (2925 mg/m3) at the end of school days, indicating the impact of occupancy rates particularly at one of the preschools. Regarding comfort parameters, temperature exerted a significant influence on O3 concentrations, while RH values were significantly correlated with TVOC levels in indoor air of preschools, particularly during the late afternoon periods.

description: The Palaeoproterozoic Hekou Group, an outcrop along the SW-margin of the Yangtze Block, consists of volcanic and sedimentary rocks that experienced greenschist facies metamorphism and was intruded by gabbroic and granitic plutons. The sedimentary rocks consist of coarse to fine-grained siliciclastic and carbonate rocks including quartzite, mica schists, polymictic meta-conglomerates and marble, whereas volcanic rocks consist of sodic lava and pyroclastic rocks including albitites, interbeded metatuffs, and metabasalts. Metatuffs from five layers have zircon U–Pb age of 1710 ± 18 Ma (MSWD = 1.6), 1637 ± 7 Ma (MSWD = 0.65), 1601 ± 15 Ma (MSWD = 0.94), 1661 ± 7 Ma (MSWD = 1.4), and 1718 ± 11 Ma (MSWD = 0.3) and these ages show that the Hekou Group deposited at ~1.7–1.6 Ga. The high content of light rare earth element (LREE), the low content of highrare earth element (HREE) and negative Ti anomalies, relatively high content of incompatible fluid-insoluble elements (Nb, Ta, and Th), and the high varied εNd(t) values (−6.0 to +4.6) of the metavolcanic rocks show that these rocks are formed in back-arc basin. Our study also implies that the Yangtze Block also underwent subduction-related, continental margin accretion on its SW-margin during the growth of the Nuna supercontinent at ~1.7–1.6 Ga.

description: Higher Education Institutions (HEI) play a strategically important role in the multidimensional transformations needed to achieve more sustainable ways of living in this world. By applying a holistic or “whole institution approach,” they can promote and implement sustainability in research, teaching, campus management, and carry out the “third mission” of universities to generate trans-disciplinary knowledge useful for society. This publication showcases various projects and initiatives developed by universities from Canada, Chile, China, Colombia, Germany, Israel, Mexico, Peru, and Russia to promote the topic of sustainability in governance, teaching, research, and campus management. By presenting the key issues, recommendations, and lessons learned from these initiatives, it outlines innovative and diverse approaches that contribute to fostering sustainability at HEIs. These cases highlight experiences from all over the world that can be adopted by interested HEIs anywhere, in particular those HEIs forced to operate under conditions of serious resource scarcity and in contexts where sustainability is not yet a major part of academic activities. We also hope that this publication will be the start for closer exchanges on sustainability initiatives among universities all over the world.

Distributed Adaptive Signal Fusion for Fractional Programs

Publisher: name: arXiv

Subjects: subject: Signal Processing (eess.SP)
subject: FOS: Electrical engineering, electronic engineering, information engineering

description: The distributed adaptive signal fusion (DASF) framework allows to solve spatial filtering optimization problems in a distributed and adaptive fashion over a bandwidth-constrained wireless sensor network. The DASF algorithm requires each node to sequentially build a compressed version of the original network-wide problem and solve it locally. However, these local problems can still result in a high computational load at the nodes, especially when the required solver is iterative. In this paper, we study the particular case of fractional programs, i.e., problems for which the objective function is a fraction of two continuous functions, which indeed require such iterative solvers. By exploiting the structure of a commonly used method for solving fractional programs and interleaving it with the iterations of the standard DASF algorithm, we obtain a distributed algorithm with a significantly reduced computational cost compared to the straightforward application of DASF as a meta-algorithm. We prove convergence and optimality of this "fractional DASF" (FDASF) algorithm and demonstrate its performance via numerical simulations.

description: In this paper we propose a new parameterization algorithm based on nonlinear prediction, which is an extension of the classical LPC parameters. The parameters performances are estimated by two different methods: the Arithmetic-Harmonic Sphericity (AHS) and the Auto-Regressive Vector Model (ARVM). Two different methods are proposed for the parameterization based on the Neural Predictive Coding (NPC): classical neural networks initialization and linear initialization. We applied these two parameters to speaker identification. The fist parameters obtained smaller rates. We show for the first parameters how they can be combined with the classical parameters (LPCC, MFCC, etc.) in order to improve the results of only one classical parameterization (MFCC provides 97.55% and MFCC+NPC 98.78%). For the linear initialization, we obtain 100% which is great improvement. This study opens a new way towards different parameterization schemes that offer better accuracy on speaker recognition tasks.

description: BACKGROUND:There is currently no effective treatment for promoting regeneration of injured nerves in patients who have sustained injury to the central nervous system such as spinal cord injury. Chondroitinase ABC is an enzyme, which promotes neurite outgrowth and regeneration. It has shown considerable promise as a therapy for these conditions. The aim of the study is to determine if targeting chondroitinase ABC expression to the neuronal axon can further enhance its ability to promote axon outgrowth. Long-distance axon regeneration has not yet been achieved, and would be a significant step in attaining functional recovery following spinal cord injury. METHODOLOGY/PRINCIPAL FINDINGS:To investigate this, neuronal cultures were transfected with constructs encoding axon-targeted chondroitinase, non-targeted chondroitinase or GFP, and the effects on neuron outgrowth and sprouting determined on substrates either permissive or inhibitory to neuron regeneration. The mechanisms underlying the observed effects were also explored. Targeting chondroitinase to the neuronal axon markedly enhances its ability to promote neurite outgrowth. The increase in neurite length is associated with an upregulation of β-integrin staining at the axonal cell surface. Staining for phosphofocal adhesion kinase, is also increased, indicating that the β-integrins are in an activated state. Expression of chondroitinase within the neurons also resulted in a decrease in expression of PTEN and RhoA, molecules which present a block to neurite outgrowth, thus identifying two of the pathways by which ChABC promotes neurite outgrowth. CONCLUSIONS / SIGNIFICANCE:The novel finding that targeting ChABC to the axon significantly enhances its ability to promote neurite extension, suggests that this may be an effective way of promoting long-distance axon regeneration following spinal cord injury. It could also potentially improve its efficacy in the treatment of other pathologies, where it has been shown to promote recovery, such as myocardial infarction, stroke and Parkinson's disease.

description: Brief summaries describing the function of each gene's product(s) are of great value to the research community, especially when interpreting genome-wide studies that reveal changes to hundreds of genes. However, manually writing such summaries, even for a single species, is a daunting task; for example, the Drosophila melanogaster genome contains almost 14 000 protein-coding genes. One solution is to use computational methods to generate summaries, but this often fails to capture the key functions or express them eloquently. Here, we describe how we solicited help from the research community to generate manually written summaries of D. melanogaster gene function. Based on the data within the FlyBase database, we developed a computational pipeline to identify researchers who have worked extensively on each gene. We e-mailed these researchers to ask them to draft a brief summary of the main function(s) of the gene's product, which we edited for consistency to produce a 'gene snapshot'. This approach yielded 1800 gene snapshot submissions within a 3-month period. We discuss the general utility of this strategy for other databases that capture data from the research literature.

description: The four positional isomers of nitrocatechol monobenzyl ether were prepared as intermediates to nitrobenzodioxanes directly from 2-benzyloxyphenol or, through two-four steps, from catechol. These preparations addressed the issue of the certain identification of the nitration products prescinding from chemical correlation to the synthetic precursors because the positional isomers are very similar for some properties and analytical data available from the literature are largely incomplete and not conclusive. The here provided NMR, DSC, and acidity data unequivocally distinguish each nitrocatechol monobenzyl ether from its regioisomers.

description: During early pregnancy, decidual innate lymphoid cells (dILCs) interact with surrounding maternal cells and invading fetal extravillous trophoblasts (EVT). Here, using mass cytometry, we characterise five main dILC subsets: decidual NK cells (dNK)1-3, ILC3s and proliferating NK cells. Following stimulation, dNK2 and dNK3 produce more chemokines than dNK1 including XCL1 which can act on both maternal dendritic cells and fetal EVT. In contrast, dNK1 express receptors including Killer-cell Immunoglobulin-like Receptors (KIR), indicating they respond to HLA class I ligands on EVT. Decidual NK have distinctive organisation and content of granules compared with peripheral blood NK cells. Acquisition of KIR correlates with higher granzyme B levels and increased chemokine production in response to KIR activation, suggesting a link between increased granule content and dNK1 responsiveness. Our analysis shows that dILCs are unique and provide specialised functions dedicated to achieving placental development and successful reproduction.
Experimental studies of antenna array systems using software defined radio testbed

description: This thesis is concerned with multiple-antenna wireless communication systems, initially, a forward-backward auto-regressive process is presented to predict the down-link channel of a LTE-TDD multi-user MIMO system. With the proposed channel prediction algorithm, an integrated block diagonalisation (BD) precoding scheme is proposed for improving the sum system capacity in a time-variant Rayleigh fading channel environment based on a Jakes model. Furthermore, a hybrid testbed, constructed using National Instrument PXIe platform, was used to compare the performance with that of the conventional BD precoding method where channel prediction is not present. Then various novel synchronisation and calibration schemes are presented and studied using another software defined radio (SDR) antenna array testbed which includes an array of USRP boards manufactured by Ettus Research and National Instrument. This testbed provides a flexible platform to perform a wide range experimental array processing studies with different geometries and a varying number of antennas. Furthermore, various localisation algorithms are evaluated within a controlled anechoic environment as well as outdoors. In particular, large aperture array (LAA) localisation techniques and multiple signal classification (MUSIC) techniques are studied for locating the position of a signal source operating in both in the far field and in the near-far field of the array. Finally, this thesis presents a novel array element pattern synthesis algorithm. Throughout the thesis, extensive experiments are presented to analyse the performance of the developed algorithms using an array SDR testbed made of off-the-shelf antennas.

description: A highly efficient, green as well as atom economical protocol for the synthesis of substituted spirooxindoles from m-ZrO2 NPs catalyzed multicomponent reaction of isatin derivatives with ethyl cyanoacetate and 1,3-dicarbonyl compounds in a ball mill has been established. Because of the simple and readily available starting materials, easy operation, and high bioactivity of substituted spirooxindoles, this strategy can be broadly applied to medicinal chemistry. The recyclability of the m-ZrO2 Nps catalyst is another emphasis of proposed methodology.

description: The four positional isomers of nitrocatechol monobenzyl ether were prepared as intermediates to nitrobenzodioxanes directly from 2-benzyloxyphenol or, through two-four steps, from catechol. These preparations addressed the issue of the certain identification of the nitration products prescinding from chemical correlation to the synthetic precursors because the positional isomers are very similar for some properties and analytical data available from literature are largely incomplete and not conclusive. The here provided NMR, DSC and acidity data unequivocally distinguish each nitrocatechol monobenzyl ether from its regioisomers.

description: As mobile genetic elements, the diversity and activity of the Tyl-copia retrotransposons are key contributors to genome organisation and evolution, which have been investigated in many plants but little in the tea plant, Camellia sinensis. We selected a total of 12 varieties of tea plant distributed across a large geographical area and sequenced the reverse transcriptase (RT) sequences of Ty1-copia retrotransposons using degenerate primers. The sequences that were widespread among tea varieties, were approximately 260 bp in length and exhibited high heterogeneity among tea plants. The RT sequences from tea plants were similar to other known Ty1-copia retrotransposon RT sequences. Phylogenetic analysis showed that tea RT sequences were closely related to those from woody plants, such as pear, poplar and apple. In contrast, they were more distantly related to RT sequences from herbaceous plants, such as tomato and rice. Activity assay revealed that Ty1-copia retrotransposons are transcriptionally active during the normal development of tea plants. These results will support further research on Ty1-copia retrotransposons in C. sinensis.

description: In the current IT world, developers write code while system operators run the code mostly as a black box. The connection between both worlds is typically established with log messages: the developer provides hints to the (unknown) operator, where the cause of an occurred issue is, and vice versa, the operator can report bugs during operation. To fulfil this purpose, developers write log instructions that are structured text commonly composed of a log level (e.g., "info", "error"), static text ("IP {} cannot be reached"), and dynamic variables (e.g. IP {}). However, as opposed to well-adopted coding practices, there are no widely adopted guidelines on how to write log instructions with good quality properties. For example, a developer may assign a high log level (e.g., "error") for a trivial event that can confuse the operator and increase maintenance costs. Or the static text can be insufficient to hint at a specific issue. In this paper, we address the problem of log quality assessment and provide the first step towards its automation. We start with an in-depth analysis of quality log instruction properties in nine software systems and identify two quality properties: 1) correct log level assignment assessing the correctness of the log level, and 2) sufficient linguistic structure assessing the minimal richness of the static text necessary for verbose event description. Based on these findings, we developed a data-driven approach that adapts deep learning methods for each of the two properties. An extensive evaluation on large-scale open-source systems shows that our approach correctly assesses log level assignments with an accuracy of 0.88, and the sufficient linguistic structure with an F1 score of 0.99, outperforming the baselines. Our study shows the potential of the data-driven methods in assessing instructions quality and aid developers in comprehending and writing better code.

Evolution and dynamics of the plumbing system of Popocatépetl Volcano, Mexico
Creators: name: Mangler, Martin Friedrich
Publisher: name: Imperial College London
Year: 2018

description: Popocatépetl is an active arc volcano in the densely populated metropolitan area of Mexico City. Current mildly explosive activity is contrasted with at least ten voluminous effusive eruptions and six Plinian eruptions in the past ~23.5 ka. Previous work focuses on present-day and past explosive activity and neglects effusive eruptions, resulting in an incomplete understanding of Popocatépetl’s plumbing system. This thesis presents the first comprehensive stratigraphic, whole rock geochemical and petrological investigation of effusive and explosive eruptions in the last ~23.5 ka, with implications on the long-term evolution and dynamics of the plumbing system. Lavas and pumices are andesites – dacites with relatively homogeneous whole rock characteristics modified by crustal contamination. Parental melts feeding Popocatépetl volcano are olivine – chromite – augite bearing magmas derived from a depleted sub-arc mantle. The shallow plumbing system consists of a mafic reservoir crystallising orthopyroxene (Mg# >78), clinopyroxene (Mg# >82) and minor chromite at 1000 – 1115°C, and an evolved reservoir at ~960°C crystallising plagioclase (An50-28), orthopyroxene (Mg# <71), clinopyroxene (Mg# <79) and minor apatite, ilmenite and magnetite. Frequent injections of the mafic magma into the evolved reservoir produce transient mixed magmas at 960 – 1030°C, causing widespread textural and compositional disequilibria in both mafic and evolved phenocrysts. Such mafic injections are shown to occur weeks to months before explosive and effusive eruptions of the last ~2150 years. Furthermore, injection rates are higher in the years to decades before explosive eruptions compared to effusive activity, suggesting increased pressurisation of the plumbing system prior to explosive eruptions. Frequent mafic injections and magma hybridisation at Popocatépetl results in the eruption of hybrid lavas and pumices with narrow whole rock geochemical ranges containing multiple generations of mafic and evolved phenocrysts at different stages of re-equilibration. The repetitive nature of mafic injections dominates the activity, whole rock geochemistry and mineralogy of Popocatépetl volcano.
