Improving Data Services by the Creation of a Question Database
Creators: name: Clausen, Nanna Floor
Publisher: name: Zenodo
Year: 2007

description: This paper will demonstrate and discuss how a question database will be of great value for both the social science research community but also for Data Archives. The question database will hold information on every question from the questionnaires deposited in the archive. The database will be searchable from the Web via a dedicated search interface. Having access to the full and original question wording will improve data services in several ways. The paper will present the new advantages and possibilities such as 1) Users will have an additional method for identifying more precisely relevant surveys, links to all the surveys using the given question, 2) the possibility of making comparative research of the surveys using a given question, 3) support in the construction of new questions and questionnaires-new research projects as the question wordings themselves reflect the time and circumstances in which they were designed-more open access and insight in the surveys and the data via the question database. The paper will discuss issues involved in designing, creating and maintaining a question database and the benefits it creates.

description: We compare the exact evolution of an expanding three-dimensional Bose-Einstein condensate with that obtained from the effective scaling approach introduced in D. Guéry-Odelin [Phys. Rev. A 66, 033613 (2002)]. This approach, which consists in looking for self-similar solutions to be satisfied on average, is tested here in different geometries and configurations. We find that, in case of almost isotropic traps, the effective scaling reproduces with high accuracy the exact evolution dictated by the Gross-Pitaevskii equation for arbitrary values of the interactions, in agreement with the proof-of-concept of M. Modugno, G. Pagnini, and M. A. Valle-Basagoiti [Phys. Rev. A 97, 043604 (2018)]. Conversely, it is shown that the hypothesis of universal self-similarity breaks down in case of strong anisotropies and trapped geometries.

description: We report x-ray reflectivity (XR) and small angle off-specular diffuse scattering (DS) measurements from the surface of liquid Indium close to its melting point of $156^\circ$C. From the XR measurements we extract the surface structure factor convolved with fluctuations in the height of the liquid surface. We present a model to describe DS that takes into account the surface structure factor, thermally excited capillary waves and the experimental resolution. The experimentally determined DS follows this model with no adjustable parameters, allowing the surface structure factor to be deconvolved from the thermally excited height fluctuations. The resulting local electron density profile displays exponentially decaying surface induced layering similar to that previously reported for Ga and Hg. We compare the details of the local electron density profiles of liquid In, which is a nearly free electron metal, and liquid Ga, which is considerably more covalent and shows directional bonding in the melt. The oscillatory density profiles have comparable amplitudes in both metals, but surface layering decays over a length scale of $3.5\pm 0.6$ Åfor In and $5.5\pm 0.4$ Åfor Ga. Upon controlled exposure to oxygen, no oxide monolayer is formed on the liquid In surface, unlike the passivating film formed on liquid Gallium.

description: We study the dynamics of extended rod-like bodies in (or associated with) membranes and films. We demonstrate a striking difference between the mobilities in films and bulk fluids, even when the dissipation is dominated by the fluid stress: for large inclusions we find that rotation and motion perpendicular to the rod axis exhibits purely local drag, in which the drag coefficient is algebraic in the rod dimensions. We also study the dynamics of the {\em internal} modes of a semiflexible inclusion and find two dynamical regimes in the relaxation spectrum.

description: We have developed and characterized a symmetry-protected superconducting qubit that offers simultaneous exponential suppression of energy decay from charge and flux noise, and dephasing from flux noise. The qubit consists of a Cooper-pair box (CPB) shunted by a superinductor, thus forming a superconducting loop. Provided the offset charge on the CPB island is an odd number of electrons, the qubit potential corresponds to that of a $\cos ϕ/ 2$ Josephson element, preserving the parity of fluxons in the loop via Aharonov-Casher interference. In this regime, the logical-state wavefunctions reside in disjoint regions of phase space, thereby ensuring the protection against energy decay. By switching the protection on, we observed a ten-fold increase of the decay time, reaching up to $100 μ\mathrm{s}$. Though the qubit is sensitive to charge noise, the sensitivity is much reduced in comparison with the charge qubit, and the charge-noise-induced dephasing time of the current device exceeds $1 μ\mathrm{s}$. Implementation of the full dephasing protection can be achieved in the next-generation devices by combining several $\cos ϕ/ 2$ Josephson elements in a small array.

A Darwinian City : decentering humans in architectural design in an evolving urban ecology
Creators: name: Wen, Angela
Publisher: name: The University of British Columbia
Year: 2021

description: Human activity and the creation of anthropocentric environments are undoubtedly the most significant catalysts for evolution on this planet today. Today, approximately 55% of the world's population, 4.2 billion inhabitants, live in cities, and this trend is predicted to increase to 70% by 2050. However, migrating to cities is not just exclusive to humans. This concrete jungle is home to a menagerie of creatures attracted to plentiful food and protection from hunting or other natural dangers. The study of urban evolution has rapidly become the frontier of biology and can help us understand how evolution in urban populations contributes to conserving sensitive ecosystems. The implications of this can help establish sustainable urban environments that will improve human health. Architects have a social responsibility to reflect this social shift in our designs to create harmony between nature and humans. This thesis looks at the built environment through the lens of nonhuman species as equal citizens. By anticipating the emergence of nonhuman citizens in the city, architecture can create a reconciliation of humans with nature. Located in the southeast corner of False Creek, Vancouver, an empty lot is earmarked for a multi-building development. This thesis is a critique of this master plan. Rather than the standard method of human-centred design, this project proposes a new ecocentric way to design this site. Its objective is to think of architecture on the farthest end of the human-nature spectrum: humans are participants with nature.
Growth of matter fluctuations in $f(R,T)$ Gravity

description: In this work, I present for the first time the analysis concerning the growth of matter fluctuations in the framework of $f(R,T)$ modified gravity where I presume $f(R,T) = R + λT$, where $R$ denote the Ricci scalar, $T$ the trace of the energy-momentum tensor and $λ$ a constant. I first solve the Friedman equations assuming a dust universe ($ω=0$) for the Hubble parameter $H(z)$ and then employ it in the equation of matter density fluctuations $δ(z)$ to solve for $δ(z)$ and the growth rate $f(z)$. Next, I proceed to show the behavior of $f(z)$ and $δ(z)$ with redshift for some values of $λ$ with observational constraints. Finally, following the prescription of \cite{growft41}, I present an analytical expression for the growth index $γ$ which is redshift dependent and the expression reduces to $3/5$ for $λ=0$, which is the growth index for a dust universe.

description: Having ruled out the possibility that stellar objects are the main contributor of the dark matter embedding galaxies, microlensing experiments cannot exclude the hypothesis that a significant fraction of the Milky Way dark halo might be made of MACHOs with masses in the range $0.5-0.8 \msun$. Ancient white dwarfs are generally considered the most plausible candidates for such MACHOs. We report the results of a search for such white dwarfs in a proper motion survey covering a 0.16 sqd field at three epochs at high galactic latitude, and 0.938 sqd at two epochs at intermediate galactic latitude (VIRMOS survey), using the CFH telescope. Both surveys are complete to I = 23, with detection efficiency fading to 0 at I = 24.2. Proper motion data are suitable to separate unambiguously halo white dwarfs identified by belonging to a non rotating system. No candidates were found within the colour-magnitude-proper motion volume where such objects can be safely discriminated from any standard population as well as from possible artefacts. In the same volume, we estimate the maximum white dwarf halo fraction compatible with this observation at different significance levels if the halo is at least 14 gigayears old and under different ad hoc initial mass functions. Our data alone rules out a halo fraction greater than 14% at 95% confidence level. Combined with two previous investigations exploring comparable volumes pushes the limit below 4 % (95% confidence level) or below 1.3% (64% confidence), this implies that if baryonic dark matter is present in galaxy halos, it is not, or it is only marginally in the form of faint hydrogen white dwarfs.

description: X-ray reflectivity measurements on the free surface of liquid Sn are presented. They exhibit the high-angle peak, indicative of surface-induced layering, also found for other pure liquid metals (Hg, Ga and In). However, a low-angle peak, not hitherto observed for any pure liquid metal, is also found, indicating the presence of a high-density surface layer. Fluorescence and resonant reflectivity measurements rule out the assignment of this layer to surface-segregation of impurities. The reflectivity is modelled well by a 10% contraction of the spacing between the first and second atomic surface layers, relative to that of subsequent layers. Possible reasons for this are discussed.

description: Created in 2002 by Act 613 the Ghana AIDS Commission established Monitoring Evaluation Focal Persons at all levels to facilitate the coordination of the national response against HIV/AIDS. This decentralised monitoring mechanism effectively addresses the complex nature of the determinants of HIV transmission. The Focal Persons ensure the implementation of Local ME Plans. They do this by collecting, collating and compiling routine data for assessing the local response to HIV/AIDS. Various open data storage and retrieval tools (CRIS, EpiInfo) are available to assist in this vein. Although information may be collected at all levels, lapses in standardisation of reporting formats may lead to decision-making vacuums because some agencies have different ME targets. nbsp;Although facing enormous challenges, the HIV/AIDS ME experience in Ghana has been successful because community, district, regional, national and global monitoring are linked to a common goal set out in the national ME plan.

description: Poly- and single-crystalline Na$_x$CoO$_2$ has been successfully intercalated with H$_2$O and D$_2$O as confirmed by X-ray diffraction and thermogravimetric analysis. Resistivity, magnetic susceptibility, and specific heat measurements show bulk superconductivity with T$_c$ close to 5 K in both cases. The substitution of deuterium for hydrogen has an effect on T$_c$ of less than 0.2 K. Investigation of the resistivity anisotropy of Na$_x$CoO$_2\cdot$yH$_2$O single crystals shows: (a) almost zero resistivity below T$_c$, and (b) an abrupt upturn at $T^* \sim$ 52 K in both the $\it {ab}$ plane and the $\it {c}$ direction. The implications of our results on the possible superconducting mechanism will be discussed.

description: The synthesis of new materials with novel or useful properties is one of the most important drivers in the fields of condensed matter physics and materials science. Discoveries of this kind are especially significant when they point to promising future basic research and applications. Van der Waals bonded materials comprised of lower-dimensional building blocks have been shown to exhibit emergent properties when isolated in an atomically thin form1-8. Here, we report the discovery of a transition metal chalcogenide in a heretofore unknown segmented linear chain form, where basic building blocks each consisting of two hafnium atoms and nine tellurium atoms (Hf2Te9) are van der Waals bonded end-to-end. First-principle calculations based on density functional theory reveal striking crystal-symmetry-related features in the electronic structure of the segmented chain, including giant spin splitting and nontrivial topological phases of selected energy band states. Atomic-resolution scanning transmission electron microscopy reveals single segmented Hf2Te9 chains isolated within the hollow cores of carbon nanotubes, with a structure consistent with theoretical predictions. Van der Waals-bonded segmented linear chain transition metal chalcogenide materials could open up new opportunities in low-dimensional, gate-tunable, magnetic and topological crystalline systems.

description: We show that Ozsváth-Szabó's bordered algebra used to efficiently compute knot Floer homology is a graded flat deformation of the regular block of a $\mathfrak{q}$-presentable quotient of parabolic category $\mathcal{O}$. We identify the endomorphism algebra of a minimal projective generator for this block with an explicit quotient of the Ozsváth-Szabó algebra using Sartori's diagrammatic formulation of the endomorphism algebra. Both of these algebras give rise to categorifications of tensor products of the vector representation $V^{\otimes n}$ for $U_q(\mathfrak{gl}(1|1))$. Our isomorphism allows us to transport a number of constructions between these two algebras, leading to a new (fully) diagrammatic reinterpretation of Sartori's algebra, new modules over Ozsváth-Szabó's algebra lifting various bases of $V^{\otimes n}$, and bimodules over Ozsváth-Szabó's algebra categorifying the action of the quantum group element $F$ and its dual on $V^{\otimes n}$.

description: Lattice stability in a model of antiferromagnetic ring coupled to adiabatic phonons is investigated for different values of the spin and numbers of magnetic sites. The magneto-elastic transition is shown to be heavily affected by the spin value, displaying a qualitative difference in the nature of the instability for spin one-half. Among the different synthesized materials, Cu$_8$ seems to be the best candidate to observe lattice dimerization in these systems. Our analysis excludes stable lattice distortions in higher spin rings. The effects of thermal fluctuations are studied in the Cu$_8$ model, where a characteristic crossover temperature is estimated.

description: For any symmetric key cryptosystem with $n$-bit secret key, the key can be recovered in $O(2^{n/2})$ exploiting Grover search algorithm, resulting in the effective key length to be half. In this direction, subsequent work has been done on AES and some other block ciphers. On the other hand, lightweight ciphers like SIMON was left unexplored. In this backdrop, we present Grover's search algorithm on all the variants of SIMON and enumerate the quantum resources to implement such attack in terms of NOT, CNOT and Toffoli gates. We also provide the T-depth of the circuits and the number of qubits required for the attack. We show that the number of qubits required for implementing Grover on SIMON $2n/mn$ is $O(2nr+mn)$, where $r$ is the number of chosen plaintext-cipher text pairs. We run a reduced version of SIMON in IBMQ quantum simulator and the 14-qubits processor as well. We found that where simulation supports theory, the actual implementation is far from the reality due to the infidelity of the gates and short decoherence time of the qubits. The complete codes for all version of SIMON have also been presented.

description: Al-Mg-Si alloys with total solute contents ranging from 0.8 to 1.4 wt.% were solutionised, quenched and then artificially aged (AA) at 180 °C, after which positron annihilation lifetime spectroscopy was applied to obtain information about precipitation and vacancy evolution during preceding ageing. Hardness and electrical resistivity measurements were carried out to complement these measurements. AA was carried out in four different heating media, which allowed for varying the heating rate from 2.4 K/s to 170 K/s. The main result of the study is that there is a competition between vacancy losses and precipitation. Any precipitation taking place during quenching or during heating to the AA temperature helps to prevent vacancies from going to sinks and allows them to assist in solute clustering. Higher solute content, slower heating to 180 °C and natural pre-ageing before AA were found to have a comparable effect.

description: We propose three regularization-based speaker adaptation approaches to adapt the attention-based encoder-decoder (AED) model with very limited adaptation data from target speakers for end-to-end automatic speech recognition. The first method is Kullback-Leibler divergence (KLD) regularization, in which the output distribution of a speaker-dependent (SD) AED is forced to be close to that of the speaker-independent (SI) model by adding a KLD regularization to the adaptation criterion. To compensate for the asymmetric deficiency in KLD regularization, an adversarial speaker adaptation (ASA) method is proposed to regularize the deep-feature distribution of the SD AED through the adversarial learning of an auxiliary discriminator and the SD AED. The third approach is the multi-task learning, in which an SD AED is trained to jointly perform the primary task of predicting a large number of output units and an auxiliary task of predicting a small number of output units to alleviate the target sparsity issue. Evaluated on a Microsoft short message dictation task, all three methods are highly effective in adapting the AED model, achieving up to 12.2% and 3.0% word error rate improvement over an SI AED trained from 3400 hours data for supervised and unsupervised adaptation, respectively.

description: In this paper, we discuss the transport phenomena of electromagnetic waves in a two-dimensional random system which is composed of arrays of electrical dipoles, following the model presented earlier by Erdogan, et al. (J. Opt. Soc. Am. B {\bf 10}, 391 (1993)). A set of self-consistent equations is presented, accounting for the multiple scattering in the system, and is then solved numerically. A strong localization regime is discovered in the frequency domain. The transport properties within, near the edge of and nearly outside the localization regime are investigated for different parameters such as filling factor and system size. The results show that within the localization regime, waves are trapped near the transmitting source. Meanwhile, the diffusive waves follow an intuitive but expected picture. That is, they increase with travelling path as more and more random scattering incurs, followed by a saturation, then start to decay exponentially when the travelling path is large enough, signifying the localization effect. For the cases that the frequencies are near the boundary of or outside the localization regime, the results of diffusive waves are compared with the diffusion approximation, showing less encouraging agreement as in other systems (Asatryan, et al., Phys. Rev. E {\bf 67}, 036605 (2003).)

description: Publicly funded research data deposited into data archives are public goods. Under voluntary contribution, data are under-deposited and under-prepared. Either punishment or reward should be available to motivate researchers to deposit data and spend more effort in data preparation. This paper built a simple mathematic model to analyze the effects of punishment and reward. Hopefully, it could be help policy makers decide the incentive mechanisms for data sharing.

description: The recent worldwide outbreak of the novel coronavirus (COVID-19) has opened up new challenges to the research community. Artificial intelligence (AI) driven methods can be useful to predict the parameters, risks, and effects of such an epidemic. Such predictions can be helpful to control and prevent the spread of such diseases. The main challenges of applying AI is the small volume of data and the uncertain nature. Here, we propose a shallow long short-term memory (LSTM) based neural network to predict the risk category of a country. We have used a Bayesian optimization framework to optimize and automatically design country-specific networks. The results show that the proposed pipeline outperforms state-of-the-art methods for data of 180 countries and can be a useful tool for such risk categorization. We have also experimented with the trend data and weather data combined for the prediction. The outcome shows that the weather does not have a significant role. The tool can be used to predict long-duration outbreak of such an epidemic such that we can take preventive steps earlier

description: We show that P-Vortices in the confinement phase of SU(2) lattice gauge theory form one large percolating (infrared) cluster and a number of small (ultraviolet) clusters. We discuss the interrelation of clusters of monopoles in the maximal Abelian projection with clusters of P-vortices. To extract P-vortices we use both direct and indirect central projections and find qualitatively similar results.

The Importance of Data Visualization in Data Literacy
Creators: name: Stamatel, Janet
Publisher: name: Zenodo
Year: 2007

description: Data visualization is an important means by which we analyze information, particularly in the current social climate where visual media are so prevalent.nbsp; Although some disciplines, such as statistics and computer science, have invested considerable resources in studying and improving data visualization techniques, social scientists have not fully embraced this trend.nbsp; This paper argues that data visualization is an important aspect of quantitative reasoning and data literacy.nbsp; It presents Edward Tufte's principles of design and illustrates how they can be applied to empirical research results using an example from criminology.nbsp; It discusses the skills and software needed to effectively implement these design principles and addresses the technical limitations of applying these techniques to typical social science analyses.

The clustering of galaxies around three damped Ly-alpha absorbers at Redshift Three

description: [Abridged] We present out results on the cross-correlation of Lyman break galaxies (LBGs) around three damped \Ly absorbers (DLAs) at redshift three from deep multi-band MOSAIC images obtained at the KPNO 4m. The large area of the MOSAIC images, 0.31 $°^2$ allows us to probe the clustering of LBGs on scales up to 20 Mpc co-moving to test whether DLA halos are more or less massive than LBG halos. . We present our survey that covers a total of 1 deg$^2$ and contains $\sim$3,000 LBGs with photometric redshifts between 2.8 and 3.5. Within a redshift slice of width $W_z=0.15$, we find that the DLA-LBG cross-correlation is $1.6\pm 1.3$ times the LBG-LBG autocorrelation. This corresponds to a correlation length of $r_o=5\pm4.5h^{-1}$ (co-moving). The cross-correlation is most significant on scales 5-10 Mpc, and is significantly greater than zero at the $>95$% level from Monte Carlo simulations.

The data is out there. Analyzing from electronic tracks of behavior
Creators: name: Rasmussen, Karsten Boye
Publisher: name: Zenodo
Year: 2007

description: Traditional research data is primary data captured through the deliberate process of data collection, through an instrument built from themes of research, narrowing in on the relevant theories, and concluding with operationalizations of concepts and measurement of the variables that then will constitute the data foundation for the research analysis. Most often the research investigations within the broad area of social science have as their normal research objects the human subjects. The validity of the results obtained through this design is greatly affected by the coloring in obtaining socially desirable answers as well as by an often ignored bias present in low response rates. This presentation will exemplify how the electronification of human behavior supplies an added complete, reliable, and easily accessible resource for analysis both through regular content statements (exemplified by e-mails and blogs) as well as the electronic traces of behavior (exemplified by click-streams of web behavior).

We present a new method to identify would-be zero modes and nonzero modes using their symmetry and chiral properties. Here, we review the traditional method with HYP improved staggered quarks, and extend it to a completely new method which uses the chiral Ward identities and leakage patterns to achieve the goal.

Tesserodoniella

description: Biogeography of Tesserodoniella
 The discovery of Tesserodoniella in South America and its hypothesized close relationship with the Australian genera Tesserodon and Aptenocanthon leads to a series of interesting biogeographical considerations:
 1. As pointed out before, the other two canthonine species occurring in Chile belong to predominantly Neotropical genera. Scybalophagus has four species distributed in the Patagonian biogeographical subregion (as defined by Morrone 2001, 2006). A fifth species, occurring in Chile, occurs in what Morrone (2006) called the South American Transition Zone. Megathopa (with two species) is occurs from Regions IV to IX in Chile, from Córdoba to Chubut in Argentina, and in Uruguay. Neither Scybalophagus or Megathopa are closely related to or sympatric with Tesserodoniella.
 2. The presence of Tesserodoniella in the Santiago and Maule biogeographic provinces supports Morrone’s (2001, 2006) proposals on the composition and biogeographic affinities of those areas. Morrone (2001, 2006) divided South America into two regions (Neotropical and Andean) with a transition zone that roughly corresponds with the Andes. The Andean Region is included in the Austral kingdom, originating from Western Gondwana, which also includes the Antarctic, Cape (or Afrotemperate), Neoguinean, Temperate Australian, and Neozealandic regions. The Andean Region was divided by Morrone into subregions and provinces. Santiago Province is included in the Central Chilean subregion, and Maule Province in the Subantarctic subregion. However, both provinces are strongly related, as Maule is the southern limit of many distributional areas. Interestingly, the Santiago Province contains the highest number of endemic species in the southern part of South America (Morrone et al. 1997).
 3. Of the closely related Australian genera, Tesserodon is widely distributed in northern and western Australia, with two species in New Guinea; while Aptenocanthon is distributed in eastern and northern Australia (Matthews 1974, Storey 1984, Paulian 1985, Storey 1991, Storey & Monteith 2000). The biogeographical affinities between southern South America, Australia, and New Zealand, known as the southern Gondwana distributional pattern (Sanmartín & Ronquist 2004), have been illustrated by many plant and insect examples (Crisci et al. 1991, Sequeira & Farrell 2001, Sanmartín & Ronquist 2004).

description: We show that the data of a principal G-bundle over a principal circle bundle is equivalent to that of a \hat{LG} = U(1) |x LG bundle over the base of the circle bundle. We apply this to the Kaluza-Klein reduction of M-theory to IIA and show that certain generalized characteristic classes of the loop group bundle encode the Bianchi identities of the antisymmetric tensor fields of IIA supergravity. We further show that the low dimensional characteristic classes of the central extension of the loop group encode the Bianchi identities of massive IIA, thereby adding support to the conjectures of hep-th/0203218.

description: All countries, regardless of the type of society and the level of socio - economic development, to a greater or lesser degree, have a problem with the informal economy. It can be said that, the informal economy represents a part of the economy that is characterized by irregular and illegal business. The burning issue of the whole society of Republic of Serbia is informal economy. The goal is not to eliminate the so-called. «black market», because it is virtually impossible, but the goal is to reducing it on european frameworks. However, the current situation most closely resembles to the struggle against the wind. The aim of this paper is to indicate on the share of informal economy in total economic activity, then on its essential forms, as well as on the necessary measures and instruments of economic policy which will be taken to reduce its participation.
[In]-visible : A narrative on precious workers of intimate daily cleaning
Creators: name: Yang, Yang

description: Architecture needs daily support to be alive. If buildings exist as living bodies, the everyday routines are required for the functioning of this vast organism. The source of food, water and fresh air are fundamental supplements in feeding the “bones,” the “tissues,” and the “skin.” All these body parts refer to the structure, program and façade of the building, and inquire intensive maintenance to keep it alive and functional. Human activities are dusty. The facilities are enclosed factories that collect dusty particles from the working of bodies. These elements hold power to participate in degrading the building to its end. However, keeping a routine of cleaning the dust and particles is inevitably a way to maintain the space. Then the question came, who is doing all this dirty work? The project aims to explore the invisible precarious workers who maintain all the buildings while being simultaneously demanded for and disregarded by our society. The thesis dives into an investigation of architectural developments in addressing this current situation. Drawing on concepts such as tools, bodies and service spaces, the project takes from the study of unnoticeable daily intimate cleaning to hidden service space in an architectural context.
