description: Many computational methods have been developed for modeling protein-protein docking in the past, but most of them are focused on pairwise interactions of structured proteins. However, there are many biologically important biomolecular complexes that do not fall into this category of conventional pairwise interactions. Our group has been developing methods that address complex modeling problems that are not covered by the existing approaches. Here we will discuss two such extensions.
The first method we present is structure modeling for disordered protein interactions. Protein-protein interactions with an intrinsically disordered protein (IDP) are prevalent in the cell, including important signaling and regulatory pathways. The structures of complexes with IDPs are difficult to solve even by experimental methods; moreover, existing protein-peptide docking methods are not able to model them when the IDP is long. We developed a new method, IDP-LZerD, which is designed for predicting complex structures with long IDPs (Peterson et al., PLoS Comp. Biol., 2017). IDP-LZerD starts by predicting the structures of fragments of the target IDP, which are then docked to the receptor structure, and connected to build up a full-length IDP on the receptor surface. The method was tested on complexes with IDPs of up to 69 amino acid residues long, and was quite successful.
The second method we discuss is for prediction of the assembly order of multimeric protein complexes. Similar to protein folding events, it has been observed that multimeric complexes follow specific assembly orders to form the full complexes. Knowing the assembly order of a complex is important not only for understanding the biophysical mechanism of complex formation, but also for solving partial complexes in X-ray crystallography as well as artificial protein complex design and PPI drug design. However, determining assembly order by experiment is resource intensive and thus the number of complexes with known assembly order is limited. We have developed a new method, Path-LZerD, which predicts the assembly order of a multimeric heteroprotein complex by observing the actual assembly process in computational multimeric protein docking (Peterson et al., PLos Comp. Biol., 2018). It is shown that the assembly order can be correctly predicted for many cases even when the overall protein complex structure was not perfectly predicted.
Both methods not only extend the limit of the conventional protein docking methods but are also very unique in the sense that they able to provide data to biologists through generated models that are difficult to determine even by experimental methods.

description: Più è vasta la conoscenza del lessico più precisa e incisiva sarà la nostra comunicazione, al contrario una limitata padronanza della lingua restringe i pensieri e la creatività. Il mio progetto di tesi si sofferma inizialmente sull’importanza delle parole e sul perché oggi questo argomento “non gode di ottima salute”, successivamente cerca di individuare delle metodologie visive per sensibilizzare e coinvolgere le persone al tema. Concretamente “Desueto” è un libro che non si pone come soluzione alla povertà lessicale ma vuole essere un progetto visivo capace di incuriosire e invogliare alla scoperta di vocaboli ormai poco usati; al tempo stesso tramite interviste e infografiche vuole informare sul tema delle parole e il loro valore.

description: The optimal path crack model on uncorrelated surfaces, recently introduced by Andrade et al. (Phys. Rev. Lett. 103, 225503, 2009), is studied in detail and its main percolation exponents computed. In addition to beta/nu = 0.46 \pm 0.03 we report, for the first time, gamma/nu = 1.3 \pm 0.2 and tau = 2.3 \pm 0.2. The analysis is extended to surfaces with spatial long-range power-law correlations, where non-universal fractal dimensions are obtained when the degree of correlation is varied. The model is also considered on a three-dimensional lattice, where the main crack is found to be a surface with a fractal dimension of 2.46 \pm 0.05.

description: Consider a form $g(x_1,...,x_s)$ of degree $d$, having coefficients in the completion $F_q((1/t))$ of the field of fractions $F_q(t)$ associated to the finite field $F_q$. We establish that whenever $s>d^2$, then the form $g$ takes arbitrarily small values for non-zero arguments $x\in F_q[t]^s$. We provide related results for problems involving distribution modulo $F_q[t]$, and analogous conclusions for quasi-algebraically closed fields in general.

description: We report results of one-day simultaneous multiwavelength observations of Cygnus X-2 using XMM, Chandra, the European VLBI Network and the XMM Optical Monitor. During the observations, the source did not exhibit Z-track movement, but remained in the vicinity of the soft apex. It was in a radio quiescent/quiet state of < 150 microJy. Strong dip events were seen as 25% reductions in X-ray intensity. The use of broadband CCD spectra in combination with narrow-band grating spectra has now demonstrated for the first time that these dipping events in Cygnus X-2 are caused by absorption in cool material in quite a unique way. In the band 0.2 - 10 keV, dipping appears to be due to progressive covering of the Comptonized emission of an extended accretion disk corona, the covering factor rising to 40% in deep dipping with an associated column density of 3.10^{23} atom cm^{-2}. Remarkably, the blackbody emission of the neutron star is not affected by these dips, in strong contrast with observations of typical low mass X-ray binary dipping sources. The Chandra and XMM gratings directly measure the optical depths in absorption edges such as Ne K, Fe L, and O K and a comparison of the optical depths in the edges of non-dip and dip data reveals no increase of optical depth during dipping even though the continuum emission sharply decreases. Based on these findings, at orbital phase 0.35, we propose that dipping in this observation is caused by absorption in the outer disk by structures located opposite to the impact bulge of the accretion stream. With an inclination angle > 60 deg, these structures can still cover large parts of the extended ADC, without absorbing emission from the central neutral star.

description: One of the main obstacles for extracting the cosmic microwave background (CMB) signal from observations in the mm/sub-mm range is the foreground contamination by emission from Galactic component: mainly synchrotron, free-free, and thermal dust emission. The statistical nature of the intrinsic CMB signal makes it essential to minimize the systematic errors in the CMB temperature determinations. The feasibility of using simple neural networks to extract the CMB signal from detailed simulated data has already been demonstrated. Here, simple neural networks are applied to the WMAP 5yr temperature data without using any auxiliary data. A simple \emph{multilayer perceptron} neural network with two hidden layers provides temperature estimates over more than 75 per cent of the sky with random errors significantly below those previously extracted from these data. Also, the systematic errors, i.e.\ errors correlated with the Galactic foregrounds, are very small. With these results the neural network method is well prepared for dealing with the high - quality CMB data from the ESA Planck Surveyor satellite.

Genomic profiling in the placenta : toward a greater understanding of genetic variation contributing to placental insufficiency and fetal growth restriction
Creators: name: Del Gobbo, Giulia Francesca
Publisher: name: University of British Columbia
Year: 2021

description: Fetal growth restriction (FGR) is a common pregnancy complication in which the fetus does not grow to its genetic potential due to a pathological cause, which puts it at greater risk for morbidity and mortality in the perinatal period and poor health outcomes in childhood and adulthood. Although the etiology of FGR is diverse, insufficient function of the placenta underlies many cases, as the placenta is a crucial organ to support fetal growth and development and a healthy pregnancy. One of the few established genetic contributors to placental insufficiency and non-syndromic FGR is trisomy confined to the placenta. Beyond this, the contribution of smaller genomic imbalances (copy number variants) or common single nucleotide variants and their impact on gene regulation in the placenta, for example through DNA methylation, remains largely unexplored. In this thesis, I hypothesized that placental genomic imbalances, including aneuploidy and copy number variants (CNVs), and candidate single nucleotide variants in a gene relevant to DNA methylation (DNAme) are associated with poor fetal growth and/or altered placental DNAme. Using molecular-cytogenetic and microarray techniques, I assessed aneuploidy and CNVs in placentas from infants born small-for-gestational age (SGA) and adequately-grown controls. I found that confined placental mosaicism of autosomal aneuploidies or rare candidate CNVs involving genes related to placental function or growth were present in about 18% of SGA cases, and that CNV load was not associated with SGA. I also characterized a novel case of eight 2-4 Mb duplications confined to the placenta of an infant with FGR, in which the CNVs arose de novo in a cell in the trophoblast lineage. Finally, I studied two candidate single nucleotide polymorphisms in MTHFR, involved in the metabolic pathway that produces one-carbon units for methylation reactions and purine synthesis. I found that these variants were not associated with altered placental DNAme, and that there was only a trend for increased risk of placental insufficiency complications of FGR and/or preeclampsia. Through these studies, I contributed to our understanding of genetic variation in the placenta and its association with FGR and placental insufficiency, and provided a foundation from which future studies can build.

description: Introduction: Rhegmatogenous retinal detachment (RD) is still a sight-threatening and potentially blinding disease, especially if both eyes are affected. The purpose of this study is analysing the specific characteristics of bilateral rhegmatogenous RD. Methods: The files of all 5,791 consecutive eyes undergoing vitreoretinal surgery for uncomplicated RD in a single tertiary retinal centre between January 2005 and June 2021 were retrospectively reviewed. Results: A total of 300 patients (600 eyes) had bilateral retinal detachment. Interval between initial and subsequent RD surgery was 2.6 ± 2.8 (mean ± SD, median 1.5) years. Symptoms were reported by the patients for 20 ± 75 (median 5) days before presentation in the initial eye and 12 ± 32 (median 4) days in the subsequent eye. 220 patients were male (73%), and mean age at initial RD was 55 years. 183 (61%) of the initial RD eyes were phakic. In the initial eye, more patients had a detached macula, worse visual acuity, and more quadrants involved. Primary anatomic success rate was higher in the subsequent eye (90%) compared to the initial eye (83%). There was no difference in the reattachment rate of fellow eyes with primary failure in the first eye (91%) compared to those with primary success in the first eye (90%). There was a high symmetry between the eyes in terms of type of retinal break, number of breaks, and presumed localization of the causative retinal break. Conclusion: Patients with bilateral RD were more commonly male and younger than the group of all RD patients. The proportion of pseudophakia was not different. The majority of fellow eye RD occurred within 2 years after the RD in the first eye. Second eye RD was less advanced and had a better anatomical repair rate. Despite their experience in the first eye and despite typical symptoms, patients presented only after a mean of 12 days with RD in the second eye. RD in the initial and the subsequent eye showed a high symmetry. The anatomic result in the first eye is not a predictor for the anatomic result in the subsequent eye.

description: Future photometric supernova surveys will produce vastly more candidates than can be followed up spectroscopically, highlighting the need for effective classification methods based on lightcurves alone. Here we introduce boosting and kernel density estimation techniques which have minimal astrophysical input, and compare their performance on 20,000 simulated Dark Energy Survey lightcurves. We demonstrate that these methods are comparable to the best template fitting methods currently used, and in particular do not require the redshift of the host galaxy or candidate. However both methods require a training sample that is representative of the full population, so typical spectroscopic supernova subsamples will lead to poor performance. To enable the full potential of such blind methods, we recommend that representative training samples should be used and so specific attention should be given to their creation in the design phase of future photometric surveys.

description: Luminous infrared galaxies ($L_{\rm{IR}}>10^{11} L_{\odot}$) are often associated with interacting galactic systems and are thought to be powered by merger--induced starbursts and/or dust--enshrouded AGN. In such systems, the evolution of the dense, star forming molecular gas as a function of merger separation is of particular interest. Here, we present observations of the CO(3-2) emission from a sample of luminous infrared galaxy mergers that span a range of galaxy-galaxy separations. The excitation of the molecular gas is studied by examining the CO(3-2)/CO(1-0) line ratio, $r_{31}$, as a function of merger extent. We find these line ratios, $r_{31}$, to be consistent with kinetic temperatures of $T_k$=(30--50) K and gas densities of $n_{\rm{H}_2}=10^3 \rm{cm}^{-3}$. We also find weak correlations between $r_{31}$ and both merger progression and star formation efficiency ($L_{\rm{fIR}} / L_{\rm{CO(1-0)}}$). These correlations show a tendency for gas excitation to increase as the merger progresses and the star formation efficiency rises. To conclude, we calculate the contributions of the CO(3-2) line to the 850 $μ$m fluxes measured with SCUBA, which are seen to be significant ($\sim$24%).

description: Questa sperimentazione, svolta in una quinta elementare, si è posta come obiettivo quello di modificare in positivo le dinamiche che si erano instaurate all’interno del gruppo negli anni precedenti, migliorando così il clima in classe per renderlo più collaborativo. Il lavoro è stato svolto attraverso un percorso dedicato alla narrazione di sé e alle identità competenti e attraverso l’inserimento degli allievi in un progetto nel quale dovessero collaborare per raggiungere un obiettivo comune. La raccolta dei dati è stata messa a punto mediante metodi di raccolta qualitativi, come l’osservazione partecipante e il diario di bordo. Inoltre, in alcuni momenti, sono state utilizzate alcune tabelle con i corrispettivi grafici in modo da valutare la collaborazione tra i bambini. Questa sperimentazione, grazie all’analisi dei dati, ha permesso di rispondere affermativamente ai quesiti posti in partenza, dimostrando che inserire gli allievi in un percorso in cui possono conoscersi maggiormente e lavorare insieme migliora le dinamiche che si instaurano tra di loro, permettendo addirittura di cambiarle.

description: La Expresión Dramática trasciende la realidad del mero recurso pedagógico para situarse en la dimensión del auténtico proceso educativo que conduce al niño por la senda de la liberación creativa, hacia un equilibrado desarrollo psicofísico de su ser. La Expresión Dramática pone en manos del niño la mayor cantidad de materiales expresivos posibles (corporales, motores, imaginativos, espaciales y concretos) que, una vez asimilados, lo dotan de una amplia gama de posibilidades para interpretar la realidad bajo el nuevo prisma de su capacidad crítica y creadora, partiendo, lógicamente, de la observación. Dicho proceso creativo lo articulamos a través de una propuesta de sesión dramática de carácter práctico en la que trabajamos  la percepción y la sensibilización mediante la praxis educativa.

description: Play is often thought of as a light-hearted, jovial, leisurely activity we do ‘for fun’. But what happens when artists hijack these associations, and reframe the aesthetics of play? How can play (in all its various manifestations) be used in art to spotlight injustice, tell stories, and imagine a better world? Examining the practices of three contemporary artists from Indonesia – Tintin Wulia, and the artist duo of Tita Salina and Irwan Ahmett – this thesis examines how and why the artists use ideas of play for activist, interventionist and storytelling exercises. To understand the implications of using play in art, I propose an interpretive paradigm of the ‘play-response’: that is, the artists’ uses of play and performance-themed interventions as a response, dare and/or challenge to the issues confronting the world around them; using the actions of play to ‘talk back’ to authority, intervene in the status quo, and find new ways of seeing society. Works by the three artists are considered in three chapters, each dedicated to examining how activities of play are used to confront problems of the world. I analyse how the artists construct new ways of seeing issues that dominate their environment, deconstruct opaque stories by ‘playing with’ processes of reframing them, and reconstruct the possibilities of society by imagining the world as it could be. Through these acts of construction, deconstruction and reconstruction, play in art takes a variety of forms; some of which do not immediately appear to be ‘playful’, but are instead very serious modes of expression. Understanding the play-response as a distinct aesthetic ‘attitude’ and assertiveness made visible through art allows us to see how the artists have weaponised play to confront issues in the world.

description: Comparing four different (ideal and viscous) hydrodynamic models for the evolution of the medium created in 200 AGeV Au-Au collisions, combined with two different models for the path length dependence of parton energy loss, we study the effects of jet quenching on the emission-angle dependence of the nuclear suppression factor R_AA(phi) and the away-side per trigger yield I_AA(phi). Each hydrodynamic model was tuned to provide a reasonable description of the single-particle transverse momentum spectra for all collision centralities, and the energy loss models were adjusted to yield the same pion nuclear suppression factor in central Au-Au collisions. We find that the experimentally measured in-plane vs. out-of-plane spread in R_AA(phi) is better reproduced by models that shift the weight of the parton energy loss to later times along its path. Among the models studied here, this is best achieved by energy loss models that suppress energy loss at early times, combined with hydrodynamic models that delay the dilution of the medium density due to hydrodynamic expansion by viscous heating. We were unable to identify a clear tomographic benefit of a measurement of I_AA(phi) over that of R_AA(phi).

description: This paper was given by Alwaleed K. Alkhaja, Qatar National Library  Open access can provide a global solution that addresses restrictions in the interlibrary loan(ILL) or document delivery services for electronic resources. The use of academic electronicresources for ILL transactions is governed and often limited by licenses between librariesand various publishers. In an ideal situation, libraries would not require ILL or a documentdelivery for electronic resources; instead, they would rely on openly licensed material. Such a digital utopia, where all research content is available under an open license, is perhaps not yet attainable, but efforts worldwide are slowly transitioning the academic landscape. In this paper, we would like to describe our efforts at Qatar National Library for the last three years in transforming Qatar’s research output into OA. Besides providing an accessible archive of Qatar’s research, our goal has been to improve the reach of Qatar’s research to a global audience. We will describe our licensing principles, which addresses OA publications and maximize access rights for interlibrary loans, course packs and classroom use, and perpetual access. In addition, we would like to describe how our efforts are part of a global push to shift costs from access to publishing. We are at the crossroads where we need to ensure a sustainable transition, which depends on all stakeholders in the research ecosystem (both locally and on a global stage). For OA to be a global solution, it will need concerted efforts from all international counterparts. In this paper, we also will present our ideas of how we hope to improve the OA adoption moving forward, including local and regional OA advocacy, effective centralized cost-sharing through consortia, improving repository infrastructure that can support pre-prints/green OA, and a need for more licensing transparency and improved data sharing between institutions.

Zingapan, Prince Mohammad Bin Fahd University  This study aims to discuss digital access to the Learning Resources Center services and resources during the COVID-19 pandemic.The PMU LRC’s response on the pandemic situation during the periods of closure concerning resources and services is discussed and analyzed. The LRC implements new virtual services and expands the electronic resources to ensure that the PMU community is able to access the resources and information that they needed. The LRC makes efforts to gain access to their digital and physical collections as well as to provide their services remotely, with the transformation of teaching from traditional style to distance learning.There are several virtual initiatives that LRC has taken to promote digital access to the library resources and to make LRC services more efficient while challenging to deliver access to information with library closure. The researchers also examine the changes that PMU library has made to library services throughout the year 2020.

description: We report detailed theoretical investigations of the micro-mechanics and bulk elastic properties of composites consisting of randomly distributed stiff fibers embedded in an elastic matrix in two and three dimensions. Recent experiments published in Physical Review Letters [102, 188303 (2009)] have suggested that the inclusion of stiff microtubules in a softer, nearly incompressible biopolymer matrix can lead to emergent compressibility. This can be understood in terms of the enhancement of the compressibility of the composite relative to its shear compliance as a result of the addition of stiff rod-like inclusions. We show that the Poisson's ratio $ν$ of such a composite evolves with increasing rod density towards a particular value, or {\em fixed point}, independent of the material properties of the matrix, so long as it has a finite initial compressibility. This fixed point is $ν=1/4$ in three dimensions and $ν=1/3$ in two dimensions. Our results suggest an important role for stiff filaments such as microtubules and stress fibers in cell mechanics. At the same time, our work has a wider elasticity context, with potential applications to composite elastic media with a wide separation of scales in stiffness of its constituents such as carbon nanotube-polymer composites, which have been shown to have highly tunable mechanics.

E-loyalty networks in online auctions

description: Creating a loyal customer base is one of the most important, and at the same time, most difficult tasks a company faces. Creating loyalty online (e-loyalty) is especially difficult since customers can ``switch'' to a competitor with the click of a mouse. In this paper we investigate e-loyalty in online auctions. Using a unique data set of over 30,000 auctions from one of the main consumer-to-consumer online auction houses, we propose a novel measure of e-loyalty via the associated network of transactions between bidders and sellers. Using a bipartite network of bidder and seller nodes, two nodes are linked when a bidder purchases from a seller and the number of repeat-purchases determines the strength of that link. We employ ideas from functional principal component analysis to derive, from this network, the loyalty distribution which measures the perceived loyalty of every individual seller, and associated loyalty scores which summarize this distribution in a parsimonious way. We then investigate the effect of loyalty on the outcome of an auction. In doing so, we are confronted with several statistical challenges in that standard statistical models lead to a misrepresentation of the data and a violation of the model assumptions. The reason is that loyalty networks result in an extreme clustering of the data, with few high-volume sellers accounting for most of the individual transactions. We investigate several remedies to the clustering problem and conclude that loyalty networks consist of very distinct segments that can best be understood individually.

description: This paper was given by Juan Miguel Palma Peña, National Autonomous University of Mexico (UNAM); Humanities Coordination  The current situation of the SARS-CoV-2 virus pandemic responsible for Covid-19 highlights the development and implementation of multiple theoretical and empirical actions of an informative nature in which delivery and sharing data and scholarly outputs are in the focus of global attention. The opening of the research outputs is articulated so that the FAIR principles of location, accessibility, interoperability and reuse allow informational resources financed with public funds to be delivery and shared for the resolution of the current social phenomenon and to give continuity to educational and cultural activities political, scholarly, among others. The health crisis and the sharing of advances and research outputs in open access on various platforms crystallize the transition to open science, and a paradigm shift is articulated in which science is literally by and for society. This document is made based on the exploratory analysis of literature whose content is about open access, open science and Covid-19. After the analysis of the information, the interpretation and recommendations on the subject of study are made from the perspective of the library field and information studies. The aim of this document is to address the paradigm shift posed by open access and the transition to open research; as well as analyze the trends that the phenomenon of covid-19 manifests to delivery, share, exchange, make transparent and formalize the opening of research for the benefit of societies. The organization of this document consists of two sections, and they are the following: first, the evidence of open access, open science and covid-19 is analyzed based on data and actions of organizations and educational and research institutions to share information; second, the main trends for opening and sharing information are studied, such as open data, preprints and the formalization of this action.

“non”. Aspetti non convenzionali del graphic design. Sviluppo di progetti di comunicazione visiva di “oggetti grafici” differenti.

Year: 2018

description: La non convenzionalità è un atteggiamento comunicativo nato dal desiderio di oltrepassare e infrangere i limiti noti di un campo di appartenenza, il graphic design, in funzione di stabilire un approccio che si scosti dal consueto modo di intendere, dettato da convenzioni prestabilite. Come nelle avanguardie artistiche del ‘900, il fattore temporale gioca un ruolo fondamentale; il concetto di non convenzionalità può definirsi effimero, ovvero di durata circoscritta alla fase di ideazione e ai primi istanti di contatto con l’esterno, per poi entrare nei meccanismi comuni ed essere replicato grazie alla rapidità esecutiva e soprattutto di diffusione che offre oggi il web. Trattandosi di un campo fertile, mosso da iniziative con grande seguito nel panorama internazionale del graphic design come Torino Graphic Days, si è deciso di creare sviluppi comunicativi sulla base delle forme comunicative preesistenti, figurative e non, sulla base di testi preesistenti di vario genere, così da restituire uno sviluppo visivo che vada oltre il semplice utilizzo della parola. Il contenuto di ognuno di essi rimane invariato, pur evolvendo la sua forma. Ogni sviluppo si concretizza sulla base di una selezione di elementi, di uso quotidiano, individuati nell’arco di una giornata, sotto l’aspetto grafico. Mediante una metafora, quella del volo, impiegata come pretesto e filo conduttore, si è generata una narrazione composta da 6 artefatti unici tra loro, ognuno con peculiarità tecniche e progettuali mirate al contenuto e allo scopo comunicativo; queste caratteristiche sono raccolte in un opuscolo introduttivo che assume la funzione di indice e supplemento di dettaglio alla lettura dei sei sviluppi.

description: Atomistic simulations are used to study the bending of rectangular graphene nano ribbons subjected to axial stress both for free boundary and supported boundary conditions. The shape of the deformations of the buckled graphene nano ribbons, for small values of the stress, are sine waves where the number of nodal lines depend on the longitudinal size of the system and the applied boundary condition. The buckling strain for the supported boundary condition is found to be independent of the longitudinal size and estimated to be 0.86$%$. From a calculation of the free energy at finite temperature we find that the equilibrium projected two-dimensional area of the graphene nano ribbon is less than the area of a flat sheet. At the optimum length the boundary strain for the supported boundary condition is 0.48$%$.
