description: Biclustering is a data mining technique which searches for local patterns in numeric tabular data with main application in bioinformatics. This technique has shown promise in multiple areas, including development of biomarkers for cancer, disease subtype identification, or gene-drug interactions among others. In this paper we introduce EBIC.JL - an implementation of one of the most accurate biclustering algorithms in Julia, a modern highly parallelizable programming language for data science. We show that the new version maintains comparable accuracy to its predecessor EBIC while converging faster for the majority of the problems. We hope that this open source software in a high-level programming language will foster research in this promising field of bioinformatics and expedite development of new biclustering methods for big data.

description: The aim of this paper is to introduce a new technique for calculation of observables, in particular multiplicity distributions, in various statistical ensembles at finite volume. The method is based on Fourier analysis of the grand canonical partition function. Taylor expansion of the generating function is used to separate contributions to the partition function in their power in volume. We employ Laplace's asymptotic expansion to show that any equilibrium distribution of multiplicity, charge, energy, etc. tends to a multivariate normal distribution in the thermodynamic limit. Gram-Charlier expansion allows additionally for calculation of finite volume corrections. Analytical formulas are presented for inclusion of resonance decay and finite acceptance effects directly into the system partition function. This paper consolidates and extends previously published results of current investigation into properties of statistical ensembles.

description: Ammonia (NH3) is commonly used as group V precursor in gallium nitride (GaN) metalorganic chemical vapor deposition (MOCVD). The high background carbon (C) impurity in MOCVD GaN is related to the low pyrolysis efficiency of NH3, which represents one of the fundamental challenges hindering the development of high purity thick GaN for vertical high power device applications. This work uses a laser-assisted MOCVD (LA-MOCVD) growth technique to address the high-C issue in MOCVD GaN. Carbon dioxide (CO2) laser with wavelength of 9.219 um was utilized to facilitate NH3 decomposition via resonant vibrational excitation. The LA-MOCVD GaN growth rate (as high as 10 um/hr) shows a strong linear relationship with the trimethylgallium (TMGa) flow rate, indicating high effective V/III ratios and hence efficient NH3 decomposition. Pits-free surface morphology of LA-MOCVD GaN was demonstrated for films with growth rate as high as 8.5 um/hr. The background [C] in LA-MOCVD GaN films decreases monotonically as the laser power increases. A low [C] at 5.5E15 cm-3 was achieved in LA-MOCVD GaN film grown with the growth rate of 4 um/hr. Charge transport characterization of LA-MOCVD GaN films reveals high crystalline quality with room temperature mobility >1000 cm2/Vs. LA-MOCVD growth technique provides an enabling route to achieve high quality GaN epitaxy with low-C impurity and fast growth rate simultaneously. This technique can also be extended for epitaxy of other nitride-based semiconductors.

description: Context: Microservices Architecture (MSA) has received significant attention in the software industry. However, little empirical evidence exists on design, monitoring, and testing of microservices systems. Objective: This research aims to gain a deep understanding of how microservices systems are designed, monitored, and tested in the industry. Method: A mixed-methods study was conducted with 106 survey responses and 6 interviews from microservices practitioners. Results: The main findings are: (1) a combination of domain-driven design and business capability is the most used strategy to decompose an application into microservices, (2) over half of the participants used architecture evaluation and architecture implementation when designing microservices systems, (3) API gateway and Backend for frontend patterns are the most used MSA patterns, (4) resource usage and load balancing as monitoring metrics, log management and exception tracking as monitoring practices are widely used, (5) unit and end-to-end testing are the most used testing strategies, and (6) the complexity of microservices systems poses challenges for their design, monitoring, and testing, for which there are no dedicated solutions. Conclusions: Our findings reveal that more research is needed to (1) deal with microservices complexity at the design level, (2) handle security in microservices systems, and (3) address the monitoring and testing challenges through dedicated solutions.

description: We consider the optimal conduction path of the one-dimensional variable-range hopping problem. We describe a hierarchical procedure for constructing the path which is in excellent agreement with numerical results obtained from a percolation approach. The advantage of the hierarchical construction is that it is easier to analyse. We show that the distribution of hopping lengths is well approximated by a model for the repeated breaking of a stick at its weakest point, until the fragments are too strong to be broken.

Non-Hermitian skin effect as an impurity problem

Subjects: subject: Quantum Physics (quant-ph)

subject: FOS: Physical sciences

description: A striking feature of non-Hermitian tight-binding Hamiltonians is the high sensitivity of both spectrum and eigenstates to boundary conditions. Indeed, if the spectrum under periodic boundary conditions is point gapped, by opening the lattice the non-Hermitian skin effect will necessarily occur. Finding the exact skin eigenstates may be demanding in general, and many methods in the literature are based on ansatzes and on recurrence equations for the eigenstates' components. Here we devise a general procedure based on the Green's function method to calculate the eigenstates of non-Hermitian tight-binding Hamiltonians under open boundary conditions. We apply it to the Hatano-Nelson and non-Hermitian SSH models and finally we contrast the edge states localization with that of bulk states.

description: We generalize the problem of the coherent control of small quantum systems to the case where the quantum bit (qubit) is subject to a fully general rotation. Following the ideas developed in Pasini et al (2008 Phys. Rev. A 77, 032315), the systematic expansion in the shortness of the pulse is extended to the case where the pulse acts on the qubit as a general rotation around an axis of rotation varying in time. The leading and the next-leading corrections are computed. For certain pulses we prove that the general rotation does not improve on the simpler rotation with fixed axis.

Real estate portfolio diversification
Creators: name: Kurtin, Todd H.
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines the potential benefits of diversification in real estate. By calculating a set of returns for apartment blocks in Vancouver, British Columbia, two issues of diversification are dealt with: the potential of diversifying within real estate, and the benefits of including real estate in mixed-asset portfolios. To examine the potential of diversifying within real estate, the study looks at the relative proportions of systematic and unsystematic risk of real estate. Also, the paper investigates the rate at which variations of returns for randomly selected portfolios are reduced as a function of the number of properties in a portfolio. To investigate the benefits of including real estate in mixed-asset portfolios, two types of efficient portfolios are constructed: one that hedges against inflation, and the other that is mean-variance efficient. By selecting these two types of efficient portfolios, the paper considers two major investment objectives of investors: (1) that their portfolio provides a return to combat inflation; (2) that their portfolio have minimum risk for a given expected rate of return. The findings of the study show that portfolios consisting solely of real estate(of one property type in one local market) are not well diversified. The investigation found that only 29 percent of total risk is unsystematic(diversifiable). However, a large portion of the unsystematic risk can be diversified away by holding a portfolio which contains only a few properties. The findings also illustrate that real estate is a useful addition in mixed-asset portfolios. Real estate contributes to the effectiveness of both the inflation-hedged portfolio and the mean-variance efficient portfolio. In the inflation-hedged portfolio, real estate does not contribute as strongly as expected, but the results still demonstrate that real estate should be included in portfolios that are designed to hedge inflation. In the mean-variance efficient portfolio, real estate is found to have a low or negative correlation with other assets, making the potential to diversify very high.

description: To date, formal models of collective intelligence have lacked a plausible mathematical description of the relationship between local-scale interactions between highly autonomous sub-system components (individuals) and global-scale behavior of the composite system (the collective). In this paper we use the Active Inference Formulation (AIF), a framework for explaining the behavior of any non-equilibrium steady state system at any scale, to posit a minimal agent-based model that simulates the relationship between local individual-level interaction and collective intelligence (operationalized as system-level performance). We explore the effects of providing baseline AIF agents (Model 1) with specific cognitive capabilities: Theory of Mind (Model 2); Goal Alignment (Model 3), and Theory of Mind with Goal Alignment (Model 4). These stepwise transitions in sophistication of cognitive ability are motivated by the types of advancements plausibly required for an AIF agent to persist and flourish in an environment populated by other AIF agents, and have also recently been shown to map naturally to canonical steps in human cognitive ability. Illustrative results show that stepwise cognitive transitions increase system performance by providing complementary mechanisms for alignment between agents' local and global optima. Alignment emerges endogenously from the dynamics of interacting AIF agents themselves, rather than being imposed exogenously by incentives to agents' behaviors (contra existing computational models of collective intelligence) or top-down priors for collective behavior (contra existing multiscale simulations of AIF). These results shed light on the types of generic information-theoretic patterns conducive to collective intelligence in human and other complex adaptive systems.

Inflation in $R + R^2$ Gravity with Torsion

description: We examine an inflationary model in $R + R^2$ gravity with torsion, where $R^2$ denotes five independent quadratic curvature invariants; it turns out that only two free parameters remain in this model. We show that the behavior of the scale factor $a(t)$ is determined by two scalar fields, axial torsion $χ(t)$ and the totally anti-symmetric curvature $E(t)$, which satisfy two first-order differential equations. Considering $\dotχ\approx 0$ during inflation leads to a power-law inflation: $a \sim (t+ A)^p$ where $1< p \leq 2 $, and the constant $A$ is determined by the initial values of $E$, $χ$ and the two parameters. After the end of inflation, $χ$ and $E$ will enter into an oscillatory phase.

description: Trapped ions are excellent candidates for quantum computing and quantum networks because of their long coherence times, ability to generate entangled photons as well as high fidelity single- and two-qubit gates. To scale up trapped ion quantum computing, we need a Bell-state analyzer on a reconfigurable platform that can herald high fidelity entanglement between ions. In this work, we design a photonic Bell-state analyzer on a reconfigurable thin film lithium niobate platform for polarization-encoded qubits. We optimize the device to achieve high fidelity entanglement between two trapped ions and find >99% fidelity. The proposed device can scale up trapped ion quantum computing as well as other optically active spin qubits, such as color centers in diamond, quantum dots, and rare-earth ions.

description: The formation of the antihydrogen beam in the AEGIS experiment through the use of inhomogeneous electric fields is discussed and simulation results including the geometry of the apparatus and realistic hypothesis about the antihydrogen initial conditions are shown. The resulting velocity distribution matches the requirements of the gravity experiment. In particular it is shown that the inhomogeneous electric fields provide radial cooling of the beam during the acceleration.

description: Using very-high mobility GaAs/AlGaAs 2D electron Hall bar samples, we have experimentally studied the photoresistance/photovoltaic oscillations induced by microwave irradiation in the regime where both 1/B and B-periodic oscillations can be observed. In the frequency range between 27 and 130 GHz we found that these two types of oscillations are decoupled from each other, consistent with the respective models that 1/B oscillations occur in bulk while the B-oscillations occur along the edges of the Hall bars. In contrast to the original report of this phenomenon (Ref. 1) the periodicity of the B-oscillations in our samples are found to be independent of L, the length of the Hall bar section between voltage measuring leads.

Passing a Non-verbal Turing Test: Evaluating Gesture Animations Generated from Speech

description: People communicate using both speech and non-verbal signals such as gestures, face expression or body pose. Non-verbal signals impact the meaning of the spoken utterance in an abundance of ways. An absence of non-verbal signals impoverishes the process of communication. Yet, when users are represented as avatars, it is difficult to translate non-verbal signals along with the speech into the virtual world without specialized motion-capture hardware. In this paper, we propose a novel, data-driven technique for generating gestures directly from speech. Our approach is based on the application of Generative Adversarial Neural Networks (GANs) to model the correlation rather than causation between speech and gestures. This approach approximates neuroscience findings on how non-verbal communication and speech are correlated. We create a large dataset which consists of speech and corresponding gestures in a 3D human pose format from which our model learns the speaker-specific correlation. We evaluate the proposed technique in a user study that is inspired by the Turing test. For the study, we animate the generated gestures on a virtual character. We find that users are not able to distinguish between the generated and the recorded gestures. Moreover, users are able to identify our synthesized gestures as related or not related to a given utterance. Code and videos are available at https://github.com/mrebol/Gestures-From-Speech
La lingua litteraria di Guarino Veronese e la cultura teatrale a Ferrara nella prima metà del XV secolo

description: The present paper reconstructs some of the main stages in the naissance  and development of the theatrical culture in Ferrara in the first half  of the fifteenth century, focusing investigation on the teaching of  Guarino Veronese. The paper reveals the outlines of a cultural model  that, by a comparison with the classics, defines its own features and  its own way of communicating within the city. This model is investigated  through a dual perspective, emic and etic. On the one hand, we analyse  the constitutive complexity of its symbolic systems, demonstrating the  polysemy of its ceremonial events, on the other hand we examine the  dialectic relationship with the town's religious culture. Therefore, we  contextualize and justify the subsequent insight argued by Ercole  d'Este, consisting of the need to contaminate the languages and  representative forms in order to apply a more effective strategy for  political consensus.

Properties of vertically self-gravitating accretion discs with a dissipative corona

Year: 2008

description: The steady-state structure of a disc with a corona is analyzed when the vertical component of the gravitational force due to the self-gravity of the disc is considered. For the energy exchange between the disc and the corona, we assume a fraction f of the dissipated energy inside the accretion disc is transported to the corona via the magnetic tubes. Analytical solutions corresponding to a prescription for f (in which this parameter directly depends on the ratio of the gas pressure to the total pressure) or free f are presented and their physical properties are studied in detail. We show that the existence of the corona not only decreases the temperature of the disc, but also increases the surface density.The vertical component of the gravitational force due to the self-gravity of the disc decreases the self-gravitating radius and the mass of the fragments at this radius. However, as more energy is transported from the disc to the corona, the effect of the vertical component of the gravitational force due to the self-gravity of the disc on the self-gravitating radius becomes weaker, though the mass of the fragments is reduced irrespective of the amount of the energy exchange from the disc to the corona.

description: The paper is an analysis of a famous episode, the duel between  Orlando and the giant Ferraù, in the Spagna  Magliabechiana, from which I’m preparing the critical edition.
 The text of the Spagna  Magliabechiana, conserved in the  manuscript II, I 57 of the Biblioteca  Nazionale di Firenze, narrates  the life and the feats of the young knight Orlando,  Charlemagne’s  nephew, from his birth till his death. This manuscript is one of  the  Italian versions of the Charlemagne’s Spain  conquest and it is an  evidence of the transfer of the Carolingian material from  France to  Italy.
 I propose a detailed study of the sources and the narrative wheels   of the episode to create a hierarchy between all the sources used by the  author  and to establish the way those have been treated during the  redaction.

description: Infrared quasi-stellar objects (IR QSOs) are a rare subpopulation selected from ultraluminous infrared galaxies (ULIRGs) and have been regarded as promising candidates of ULIRG-to-optical QSO transition objects. Here we present NOEMA observations of the CO(1-0) line and 3 mm continuum emission in an IR QSO IRAS F07599+6508 at $z=0.1486$, which has many properties in common with Mrk 231. The CO emission is found to be resolved with a major axis of $\sim$6.1 kpc that is larger than the size of $\sim$4.0 kpc derived for 3 mm continuum. We identify two faint CO features located at a projected distance of $\sim$11.4 and 19.1 kpc from the galaxy nucleus, respectively, both of which are found to have counterparts in the optical and radio bands and may have a merger origin. A systematic velocity gradient is found in the CO main component, suggesting that the bulk of molecular gas is likely rotationally supported. Based on the radio-to-millimeter spectral energy distribution and IR data, we estimate that about 30$\%$ of the flux at 3 mm arises from free-free emission and infer a free-free-derived star formation rate of 77 $M_\odot\ {\rm yr^{-1}}$, close to the IR estimate corrected for the AGN contribution. We find a high-velocity CO emission feature at the velocity range of about -1300 to -2000 km s$^{-1}$. Additional deep CO observations are needed to confirm the presence of a possible very high-velocity CO extension of the OH outflow in this IR QSO.

Theory of Low-Temperature Hall Effect in Stripe--Ordered Cuprates

description: We investigate the effect of static anti-phase stripe order on the weak-field Hall effect of electrons on a two-dimensional square lattice with electron dispersion appropriate to the high T$_c$ cuprates. We first consider the cases where the magnitudes of the spin and charge stripe potentials are smaller than or of the same order as the bandwidth of the two-dimensional electrons, so that the electronic properties are not too strongly one-dimensional. In a model with only spin stripe potential, and at carrier concentrations appropriate to hole-doped cuprates, increasing the stripe scattering potential from zero leads to an increase in $R_H$, followed by a sign change. If the scattering amplitude is yet further increased, a second sign change occurs. The results are in semiquantitative agreement with data. In a charge-stripe-potential-only model, $R_H$ increases as the charge stripe scattering strength increases, with no sign change occurring. In a model with both spin and charge stripe potentials, $R_H$ may be enhanced or may change sign, depending on the strengths of the two scattering potentials. We also consider the case in which the magnitudes of the stripe potentials are much larger than the bandwidth, where analytical results can be obtained. In this limit, the system is quasi-one-dimensional, while $R_H$ remains finite and its sign is determined by the carrier density and the electron band parameters.
Satira politica e anticlericale nel Dialogo di Antonio Cammelli detto il Pistoia
Creators: name: Rozzoni, Alessandra

Year: 2013

description: The dialogue in prose with probable theatrical destination, that precedes the collection of poems by Antonio Cammelli said Pistoia describes the poet’s catabasis in the realm of Death. It was written between 1500 and 1502 in imitation of Dialogue of the Dead by Lucian, both in terms of style, serious and humorous, and for the recovery of some narrative episodes, and Charon by Pontano, also inspired to Lucian’s dialogues. An important innovation is the presence of the author’s stunt, which draws the text closer to the Divine Commedy and its subsequent imitations and parodies. The comparison between some scenes of the declared models highlights the stylistic features and the main themes of this dialogue, which despite not having a solid philosophical foundation, as the humanistic treatises, manages to reaffirm the importance of satire, irony and the humorous poem as a form of social protest and politics.

description: We study field theoretical models for cosmic (p,q)-superstrings in a curved space-time. We discuss both string solutions, i.e. solutions with a conical deficit, but also so-called Melvin solutions, which have a completely different asymptotic behaviour. We show that globally regular gravitating (p,q)-strings exist only in a finite domain of the parameter space and study the dependence of the domain of existence on the parameters in the model. We find that due to the interaction between strings, the parameter range where string solution exist is wider than for non-interacting strings.

description: Previous heat-capacity measurements of our group had shown the possible existence of an anomalous quantum phase containing the zero-point vacancies (ZPVs) in 2D $^{3}$He. The system is monolayer $^{3}$He adsorbed on graphite preplated with monolayer $^{4}$He at densities ($ρ$) just below the 4/7 commensurate phase ($0.8\leq ρ/ρ_{4/7}\leq 1$). We carried out pulsed-NMR measurements in order to examine the microscopic and dynamical nature of this phase. The measured decay of spin echo signals shows the non-exponential behaviour. The decay curve can be fitted with the double exponential function, but the relative intensity of the component with a longer time constant is small (5%) and does not depend on density and temperature, which contradicts the macroscopic fluid and 4/7 phase coexistence model. This slowdown is likely due to the mosaic angle spread of Grafoil substrate and the anisotropic spin-spin relaxation time $T_{2}$ in 2D systems with respect to the magnetic field direction. The inverse $T_2$ value deduced from the major echo signal with a shorter time constant, which obeys the single exponential function, decreases linearly with decreasing density from $n=1$, supporting the ZPV model.

description: An all-clear flare prediction is a type of solar flare forecasting that puts more emphasis on predicting non-flaring instances (often relatively small flares and flare quiet regions) with high precision while still maintaining valuable predictive results. While many flare prediction studies do not address this problem directly, all-clear predictions can be useful in operational context. However, in all-clear predictions, finding the right balance between avoiding false negatives (misses) and reducing the false positives (false alarms) is often challenging. Our study focuses on training and testing a set of interval-based time series classifiers named Time Series Forest (TSF). These classifiers will be used towards building an all-clear flare prediction system by utilizing multivariate time series data. Throughout this paper, we demonstrate our data collection, predictive model building and evaluation processes, and compare our time series classification models with baselines using our benchmark datasets. Our results show that time series classifiers provide better forecasting results in terms of skill scores, precision and recall metrics, and they can be further improved for more precise all-clear forecasts by tuning model hyperparameters.
Decolonizing Children’s Literature through the African Storybook’s Digital Tools

description: Children's literature plays a significant role in shaping a child's beliefs, values, and identities. Unfortunately, in many societies, this literature is dominated by Western culture and stories, perpetuating colonial perspectives and reinforcing Eurocentric worldviews. Consequently, African children interact more with content that is not relatable. The characters in the available books do not look like them, nor live in familiar-looking houses. Their food and fruits have strange names, and the setting and even the weather appear strange. While the differences may help to stretch the children’s imagination, western culture and perspective will begin to feel more authentic. The African Storybook (ASb) is an award-winning initiative that promotes the development and use of openly-licensed picture storybooks in local languages and contexts and provides a website and Apps to facilitate this process. The ASb initiative can help to decolonize children's literature in the present and future of learning. Readers can openly access the books on the website, in PDF or ePub format, by downloading them or using the ASb Reader App. The ASb Maker App on the other hand, allows African communities, teachers, children, writers, and illustrators to create and share children's storybooks in the language of their choice, thereby promoting the development and documentation of a rich, diverse, and multilingual literary heritage for African children. Interestingly, both Apps can be used offline. The paper examines the impact of the ASb digital tools on children’s reading practices while focusing on its ability to promote decolonization by providing open access to African stories and cultural perspectives. The writer demonstrates how the ASb digital tools challenge Eurocentric views and support the creation of a more inclusive and diverse literary landscape, and the potential of these digital tools to enhance mother tongue literacy among African children by providing equitable access to stories in a range of African languages. This multilingual approach can foster intercultural understanding and support linguistic diversity on the continent. This paper advocates for greater recognition of ASb resources and tools as a breakthrough OER working to decolonize children's literature in Africa. By providing open and equitable access to learning through African stories, perspectives, and cultural heritage, these tools continue to contribute to the development of a more diverse, inclusive, and equitable society.
Gamma-ray emission from dark matter wakes of recoiled black holes

description: A new scenario for the emission of high-energy gamma-rays from dark matter annihilation around massive black holes is presented. A black hole can leave its parent halo, by means of gravitational radiation recoil, in a merger event or in the asymmetric collapse of its progenitor star. A recoiled black hole which moves on an almost-radial orbit outside the virial radius of its central halo, in the cold dark matter background, reaches its apapsis in a finite time. Near or at the apapsis passage, a high-density wake extending over a large radius of influence, forms around the black hole. It is shown that significant gamma-ray emission can result from the enhancement of neutralino annihilation in these wakes. At its apapsis passage, a black hole is shown to produce a flash of high-energy gamma-rays whose duration is determined by the mass of the black hole and the redshift at which it is ejected. The ensemble of such black holes in the Hubble volume is shown to produce a diffuse high-energy gamma-ray background whose magnitude is compared to the diffuse emission from dark matter haloes alone.

W. Kaye Lamb and the Provincial Archives of British Columbia 1934-1939
Creators: name: Eso, Elizabeth Denham
Publisher: name: University of British Columbia
Year: 2010

description: The study examines W.K. Lamb's administration of the Provincial Archives of British Columbia from 1934 to 1939. Such a study is justified on the grounds that little is known about the few public archives that had been established by the 1930s. Despite difficult financial circumstances of the time, Lamb transformed the rather ill-administered Archives Department of the Legislative Library into a distinct, vital provincial archives by organizing the collections so that they could be properly used, the staff so-they could be productive and the finances of the whole department so that the needs of the work could be demonstrated. Lamb's greatest concern was to make the Archives accessible to historical researchers and the public at large. A major thrust of his efforts may be found in his establishment of the British Columbia Historical Quarterly; under his editorship it became a widely respected historical journal which brought readable, scholarly history to a wide readership and publicized the collections and work of the Archives. To understand Lamb's efforts in this regard, it is important to examine his own early life and university studies in British Columbia and Europe. Lamb's early writings, and his reviews of historical works give a good idea of Lamb's view of history and his favourite subjects. Unpublished reports of the Provincial Library and Archives as well as correspondence between Lamb and Ireland, Lamb and various amateur historians and colleagues tell the story of the development of the Archives and the Quarterly venture. Interviews with Dr. Lamb himself helped set the tone for the study and filled in many gaps in the research.

description: Pressurized hydrogen-rich compounds, which could be viewed as precompressed metallic hydrogen, exhibit high superconductivity, thereby providing a viable route toward the discovery of high-temperature superconductors. Of particular interest is to search for high-temperature superconductors with low stable pressure in terms of pressure-stabilized hydrides. In this work, with the aim of obtaining high-temperature superconducting compounds at low pressure, we attempt to study the doping effects for high-temperature superconductive $ \mathrm{H_3S} $ with supercells up to 64 atoms using first principle electronic structure simulations. As a result of various doping, we found that Na doping for $ \mathrm{H_3S} $ could lower the dynamically stable pressure by 40 GPa. The results also indicate P doping could enhance the superconductivity of $ \mathrm{H_3S} $ system, which is in agreement with previous calculations. Moreover, our work proposed an approach that could reasonably estimate the superconducting critical temperature ($ T_{c} $) of a compound containing a large number of atoms, saving the computational cost significantly for large-scale elements-doping superconductivity simulations.

description: Recently some papers in the literature have shown the presence and importance of the so-called {}"magnetic" components of gravitational waves (GWs), which have to be taken into account in the context of the total response functions of interferometers for GWs propagating from arbitrary directions. In this paper the response functions for the magnetic components are re-analysed in the full frequency dependence answering to the question of the title.

description: This Critical Guide in the Introduction to Bioinformatics series briefly outlines how to explore the neXtProt human protein database using SPARQL. While text indexation has made database contents more accessible, being able to combine search criteria for specific content permits more powerful querying, and provides a means to mine the information stored in databases. This Guide illustrates the use of the SPARQL semantic query language to interrogate neXtProt and other databases that provide SPARQL endpoints.

Specifically, the Guide introduces the concept of database ‘semantic triples’, and examines features of the neXtProt data model. On reading this Guide, and completing the exercises, users will be able to:

	identify key entities within the neXtProt data model;
	explain what these entities represent, what information they contain and what the information is used for;
	identify key SPARQL syntax elements;
	understand SPARQL tutorial examples; and
	write a SPARQL query to retrieve entries matching specific criteria.
