description: The long spin-diffusion length, spin-lifetimes and excellent optical absorption coefficient of graphene provide an excellent platform for building opto-electronic devices as well as spin-based logic in a nanometer regime. In this study, by employing density functional theory and its time-dependent version, we provide a detailed analysis of how the size and shape of graphene nanoflakes can be used to alter their magnetic structure and optical properties. As the edges of zigzag graphene nanoribbons are known to align anti-ferromagnetically and armchair nanoribbons are typically non-magnetic, a combination of both in a nanoflake geometry can be used to optimize the ground-state magnetic structure and tailor the exchange coupling decisive for ferro- or anti-ferromagnetic edge magnetism, thereby offering the possibility to optimize the external fields needed to switch magnetic ordering. Most importantly, we show that the magnetic state alters the optical response of the flake leading to the possibility of opto-spintronic applications.

description: Objective: In mood disorders chronic stress contributes to decreased glucocorticoid receptor signaling in the brain and resistance in the periphery. We hypothesized that aberrant glucocorticoid receptor function may result from genetic predisposition and that decreased GR signaling in the brain correlates with the expression of genes regulating GR complex formation. Methods: We performed the association analysis of 698 patients: 490 patients with bipolar disorder and 208 patients with major depressive disorder and 564 control subjects. We genotyped 11 variants using TaqMan assays. Gene expression in the brain tissue was done in male Wistar rats after chronic mild stress protocol. The SRSF5 serum concentration was performed using ELISA. Data were analyzed in Statistica and GraphPad. Results: We found an association of STIP1 and SRSF5 variants with major depressive disorder and BAG1 variant with bipolar disorder. Gene expression analysis in a rat model of depression confirmed significant changes in the expression of SRSF5, BAG1, and FKBP4 in the brain. For SRSF5, we observed significantly increased expression in the serum of depressed females and male rats exposed to chronic stress. Conclusions: Our results indicate the involvement of genes associated with GR function, SRSF5, BAG1, and FKBP4 with susceptibility to mood disorders.

description: En este articulo se analiza el impacto que tiene la ubicacion geografica de la explotacion en el abadnono de la actividad agraria. para ello, se utiliza el panel de explotaciones de la Encuesta de Estructuras Agrarias de Navarra. Aunque los datos son locales, las conclusiones de este trabajo pueden servir de orientacion para comprender la problematica en otras zonas, dada la diversidad agraria presente en esta region. Se ha utilzado un modelo probit jerarquizado de parametro aleatorios. Los resultados muestran que la localizacion y el contexto socioeconomico del municipio y comarca son factores significativos que modifican la probabilidad de continuacion temporal de las explotaciones agrarias. La mayor contingencia de cierre de explotaciones se da en zonas con altas tasas de actividad en el sector de la construccion, o en zonas rurales bien comunicadas y con un incipiente desarrollo del Turismo Rural. El modelo pone de manifiesto tambien que una alta tasa de activdad en la agroindustria favorece que las explotaciones continuen abiertas. Ademas, los resultados econometricos sugieren que la probabilidad de supervivencia de la agricultura a tiempo parcial y de las explotaciones agrarias pequenas varia localmente...This paper analyzes the impact of geographical location on farm exit. With this objective, panel data from the Farm Structure Survey of Navarra are used. Although the data is local, conclusions drawn from this study may be useful as an orientation to understand this problem in other zones, given the wide agricultural diversity in this region. A hierarchical probit model of random parameters is used, which implies an analytical, and consequently thematic, innovative approach. Results show that both location and the socio-economic context of the municipality and town are significant factors that modify the probability of long-term maintenance of the farms. The highest probability of farm exit is found both in zones with high activity rates in the building sector. The model also shows the positive impact of the development of local agro-industry on farms subsitence. Additionally, econometric results suggest that the stability of part-time agriculture and small farms varies locally.

description: Recent observations of the deeply embedded L1551 IRS5 system permit the detailed examination of the properties of both the stellar binary and the binary jet. For the individual components of the stellar binary, we determine their masses, mass accretion rates, effective temperatures and luminosities. For the atomic wind/jet flow, we determine the mass loss rate, yielding observationally determined values of the ratio of the mass loss to the mass accretion rate, f. For the X-ray emitting region in the northern jet, we have obtained the jet-velocity and derive the extinction and the densities on different spatial scales. Examining the observational evidence within the framework of the x-wind theory leads us to conclude that these models are indeed potentially able to account for the observational data for this deeply embedded source.

Redesigning SLAM for Arbitrary Multi-Camera Systems

description: Adding more cameras to SLAM systems improves robustness and accuracy but complicates the design of the visual front-end significantly. Thus, most systems in the literature are tailored for specific camera configurations. In this work, we aim at an adaptive SLAM system that works for arbitrary multi-camera setups. To this end, we revisit several common building blocks in visual SLAM. In particular, we propose an adaptive initialization scheme, a sensor-agnostic, information-theoretic keyframe selection algorithm, and a scalable voxel-based map. These techniques make little assumption about the actual camera setups and prefer theoretically grounded methods over heuristics. We adapt a state-of-the-art visual-inertial odometry with these modifications, and experimental results show that the modified pipeline can adapt to a wide range of camera setups (e.g., 2 to 6 cameras in one experiment) without the need of sensor-specific modifications or tuning.

description: Approximately 238,000 to 450,000 Albertans rely on private water wells for their water needs. In Canada, private well owners are responsible for monitoring and maintaining the quality of their water well, yet studies in Alberta indicate that owners do not undertake regular well maintenance or testing. This survey obtained information regarding farming and water well management practices, and drinking water preferences among private well owners in central Alberta. Questionnaires, water samples and drilling report information collected from 97 respondents between March 2015 and June 2017 were evaluated. Total coliforms were present (TC+) in 20/97 samples. There were no significant associations between well design and construction characteristics and the presence of TC+. Twenty-four and 20 respondents reported undertaking annual bacterial and chemical testing, respectively. Twenty-five respondents indicated their well had been shock chlorinated within the past three years. Concern about contamination (n = 28) was not significantly associated with increased frequency of water quality testing, well maintenance with shock chlorination, or purchasing of bottled water as an alternative drinking water. There has been little change since 2010 in the uptake of free water testing provided by Alberta Health Services. The organoleptic properties of water reported by respondents indicated shock chlorination might benefit a number of premises. Poultry producers are more likely to test their well water for bacterial and chemical contamination on an annual basis due to mandatory requirements stipulated by the poultry industry. There may be potential for a similar mandatory water testing guideline to be implemented for beef producers in Alberta. There is a need for education programs targeting rural well owners. The Working Well program information packages provided by the Government of Alberta provide an excellent source of information for water well owners. This survey indicates that new ways to disseminate this information to a broader audience are required.

description: Algorithmic Fairness is an established field in machine learning that aims to reduce biases in data. Recent advances have proposed various methods to ensure fairness in a univariate environment, where the goal is to de-bias a single task. However, extending fairness to a multi-task setting, where more than one objective is optimised using a shared representation, remains underexplored. To bridge this gap, we develop a method that extends the definition of Strong Demographic Parity to multi-task learning using multi-marginal Wasserstein barycenters. Our approach provides a closed form solution for the optimal fair multi-task predictor including both regression and binary classification tasks. We develop a data-driven estimation procedure for the solution and run numerical experiments on both synthetic and real datasets. The empirical results highlight the practical value of our post-processing methodology in promoting fair decision-making.
title: Children As Reflective Practitioners: An Action Research Project About Talk As Appraising In School Music Lesson
Creators: name: Major, Angela Elizabeth
Publisher: name: The Open University
Year: 2002

description: The purpose of this study is to define, observe and evaluate appraising of children’s own compositions in music lessons in one Secondary Comprehensive School with children aged 11 to 16 years where the researcher is also a teacher of music in the school. Through an action research framework, teaching strategies are adapted progressively to improve the learning situation that allows pupils to appraise most effectively and purposefully. The findings demonstrate different levels of talk in children about their composing work that represent their developing skills of critical thinking and analysis. From these a typology of levels of appraising is drawn up. The findings suggest that as children engage and empathise with their music compositions affectively, they appear to be able to talk more confidently about their work. The study considers whether, as children make sense of their work, they are able to understand more than their talk reveals. The need for musical vocabulary, the role of the teacher in nurturing appraising of composing work in the classroom and the role of conceptual understanding are other issues which are considered. It is suggested in the findings that as pupils develop their appraising skills to higher levels of performance, they also become effective, reflective practitioners. The research sees both the teacher researcher and the pupils engaging in appraising as reflective practitioners.

description: Polish fruit and vegetables producing sector is characterized by production fragmentation. In addition, poor technical facilities, minor use of modern technologies and the narrow application of marketing mean that producers are less competitive in the world market. A way to improve this situation is the cooperation in producer groups and organizations. Since 2004, producers who decide to cooperate receive co-financial support from national and European Community budgets. Data showing the development of producer groups and organizations including the number of operators, number of members, as well as the volume and value of production have been analyzed. The results can be used to determine the degree of self-organization in the horticultural sector in Poland. / Synopsis. Polski sektor owoców i warzyw cechuje rozdrobnienie produkcji. Dodatkowo ubogie zaplecze techniczne, nieznaczne wykorzystanie nowoczesnych technologii oraz wąskie zastosowanie marketingu powodują, że krajowi producenci są mało konkurencyjni na światowym rynku. Sposobem poprawy sytuacji jest podjęcie współdziałania w grupach i organizacjach producentów. W celu zaktywizowania producentów, decydujący się na współdziałanie otrzymują wsparcie z funduszy krajowych oraz wspólnotowych. Analizowano dane obrazujące rozwój grup i organizacji producentów w Polsce od 2004 roku, m.in. liczbę takich podmiotów, liczbę ich członków, wielkość i wartość ich produkcji. Uzyskane wyniki posłużyły do określenia stopnia zorganizowania tego sektora w Polsce.

description: ChatGPT has drawn considerable attention from both the general public and domain experts with its remarkable text generation capabilities. This has subsequently led to the emergence of diverse applications in the field of biomedicine and health. In this work, we examine the diverse applications of large language models (LLMs), such as ChatGPT, in biomedicine and health. Specifically we explore the areas of biomedical information retrieval, question answering, medical text summarization, information extraction, and medical education, and investigate whether LLMs possess the transformative power to revolutionize these tasks or whether the distinct complexities of biomedical domain presents unique challenges. Following an extensive literature survey, we find that significant advances have been made in the field of text generation tasks, surpassing the previous state-of-the-art methods. For other applications, the advances have been modest. Overall, LLMs have not yet revolutionized biomedicine, but recent rapid progress indicates that such methods hold great potential to provide valuable means for accelerating discovery and improving health. We also find that the use of LLMs, like ChatGPT, in the fields of biomedicine and health entails various risks and challenges, including fabricated information in its generated responses, as well as legal and privacy concerns associated with sensitive patient data. We believe this survey can provide a comprehensive and timely overview to biomedical researchers and healthcare practitioners on the opportunities and challenges associated with using ChatGPT and other LLMs for transforming biomedicine and health.
On Distinguishing Radions From Higgs Bosons

description: Radion couplings are almost identical to Higgs boson couplings, making it very difficult to distinguish the two states when the radion mass and vacuum expectation value are similar to those of the Higgs boson. The only real difference lies in the fact that the coupling of radions to off-shell fermions is proportional to the momentum rather than the mass of the fermion. This extra contribution gets cancelled in all tree-level processes and shows up only in loop-induced processes like Phi -> gamma gamma and Phi -> gg. We perform a careful calculation of the branching ratios and establish that they can prove crucial in clearly distinguishing a radion from a Higgs boson. This claim is made concrete by evaluating the exclusive cross-sections in a radiative process involving elementary scalars.

description: Based on Sirovich's two-fluid kinetic theory and a dodecagonal discrete velocity model, a two-dimensional 61-velocity finite-difference lattice Boltzmann method for the complete Navier-Stokes equations of binary fluids is formulated. Previous constraints, in most existing lattice Boltzmann methods, on the studied systems, like isothermal and nearly incompressible, are released within the present method. This method is designed to simulate compressible and thermal binary fluid mixtures. The validity of the proposed method is verified by investigating (i) the Couette flow and (ii) the uniform relaxation process of the two components.

description: The low power idle mode implemented by Energy Efficient Ethernet (EEE) allows network interfaces to save up to 90% of their nominal energy consumption when idling. There is an ample body of research that recommends the use of frame coalescing algorithms---that enter the low power mode as soon as there is no more traffic waiting to be sent, and delay the exit from this mode until there is an acceptable amount of traffic queued---to minimize energy usage while maintaining an acceptable performance. However, EEE capable hardware from several manufactures delays the entrance to the low power mode for a considerable amount of time (hysteresis). In this paper we augment existing EEE energy models to account for the hysteresis delay and show that, using the configuration ranges provided by manufacturers, most existing EEE networking devices are unable to obtain significant energy savings. To improve their energy efficiency, we propose to implement frame coalescing directly at traffic sources, before reaching the network interface. We also derive the optimum coalescing parameters to obtain a given target energy consumption at the EEE device when its configuration parameters are known in advance.

Numerical simulation of detailed flow through forming fabric
Creators: name: Wang, Zhishuo
Publisher: name: University of British Columbia
Year: 2010

description: The relation between the filament displacement of forming fabric and the wire mark characteristic of final paper product is investigated for the first time. The ultimate goal of this research is to understand the detailed dewatering mechanism of forming section in 3D level as well as provide a guide of forming fabric design and maintenance to obtain paper product with best quality. A 3D computational model of a square weave single-layer forming fabric has been developed by geometry modeling and commercial CFD software to simulate the detailed dewatering process of forming section. The reliability of the geometric model, grid convergence, solver settings, and boundary conditions are checked. Experimental data of wind tunnel screen is used to indirectly validate this model since currently there is no 3D experimental data of forming fabric available. Accuracy analysis is conduct with GCI (grid convergence index) method, which is widely accepted for CFD error estimation. Next, the effect of filament’s displacement on the upstream velocity distribution, which represents the fiber distribution in the formed fiber mat, is revealed. From wire mark theory, this distribution pattern can directly affect the grammage and wire mark level on paper sheet. The 2D/3D velocity plots of geometric structure with filament displacement are compared with those of uniform structure. Pressure drop and mass flow rate under both cases are also discussed. The CFD result shows the displacement of forming fabric filaments has a significant adverse influence on the uniformity of the upstream velocity distribution and mass flow rate through different open areas of the fabric. Good agreement between the simulation outcomes and experimental pressure drop values through wind tunnel screens is achieved. The pressure drop through fabric is independent of the displacement. Therefore, it cannot be used to judge the fabric uniformity. This numerical model can significantly contribute to the understanding of forming fabric with a low cost. However, 3D experimental work should be done in future to validate this model. More complex CFD models such as multi-phase model also should be developed as the next step to obtain more accurate results.

description: Wide-field H-alpha images of the Galactic plane have revealed a new supernova remnant (SNR) nearly three degrees in diameter centred at l = 107.0, b = +9.0. Deep and higher resolution H-alpha and [O III] 5007 Ang images show dozens of H-alpha filaments along the remnant's northern, western, and southwestern limbs, but few [O III] bright filaments. The nebula is well detected in the H-alpha Virginia Tech Spectral-Line Survey images, with many of its brighter filaments even visible on Digital Sky Survey images. Low-dispersion spectra of several filaments show either Balmer dominated, non-radiative filaments or the more common SNR radiative filaments with [S II]/H-alpha ratios above 0.5, consistent with shock-heated line emission. Emission line ratios suggest shock velocities ranging from <70 km/s along its western limb to ~100 km/s along its northwestern boundary. While no associated X-ray emission is seen in ROSAT images, faint 1420 MHz radio emission appears coincident with its western and northern limbs. Based on an analysis of the remnant's spatially resolved H-alpha and [O III] emissions, we estimate the remnant's distance around 1.5 - 2.0 kpc implying a physically large (dia.= 75 - 100 pc) and old (90 - 110 x 10^3 yr) SNR in its post-Sedov radiative phase of evolution expanding into a low density interstellar medium (n = 0.05 - 0.2 cm^-3) and lying some 250 - 300 pc above the Galactic plane.

description: Quantum many-body scars (QMBS) consist of a few low-entropy eigenstates in an otherwise chaotic many-body spectrum, and can weakly break ergodicity resulting in robust oscillatory dynamics. The notion of QMBS follows the original single-particle scars introduced within the context of quantum billiards, where scarring manifests in the form of a quantum eigenstate concentrating around an underlying classical unstable periodic orbit (UPO). A direct connection between these notions remains an outstanding problem. Here, we study a many-body spinor condensate that, owing to its collective interactions, is amenable to the diagnostics of scars. We characterize the system's rich dynamics, spectrum, and phase space, consisting of both regular and chaotic states. The former are low in entropy, violate the Eigenstate Thermalization Hypothesis (ETH), and can be traced back to integrable effective Hamiltonians, whereas most of the latter are scarred by the underlying semiclassical UPOs, while satisfying ETH. We outline an experimental proposal to probe our theory in trapped spin-1 Bose-Einstein condensates.

description: In this report, we discuss whether the optimal electric field to promote the growth of armchair- type nanotubes (metallic character) evaluated using the previous Huckel-Poisson method can be applied at the tip of a nanotube in a realistic system. Setting the cross-section of a nanotube and the external field by the sheath, we estimate an effective area at the sheath edge. Since the electric charge distribution in a nanotube caused by the external electric field was determined in our previous study, we obtained the electric field distribution out of a nanotube by solving the Poisson equation and clarified the structure of the electric field lines. By determining the effective area, we show the optimal interval of the catalyst metal, which is necessary to selectively grow the metallic nanotubes. When nanotubes grow thickly during the initial stage of growth, a strong electric field cannot be applied to the tips of the tubes. As a tube grows and the tube length increases, we found that the optimal electric field decreased. To maintain the chemical activity at the tip, the sheath electric field must be decreased. We estimated the decreasing rate of the sheath field to the tube length.

description: Sugar is considered as one of the first global commodities in the economic history of the world. The relations of supply and demand in the world have had a considerable influence on the development of local markets. In effect of the EU sugar market regime reform, both the European and the domestic markets are more and more reliant on the situation in the world market. The production capacity of the domestic sugar industry exceeds the demand on the internal market and therefore surpluses are exported. At the same time the market regime creates a necessity to import of 200 thousand tons of sugar in order to bridge the gap between the domestic demand and the production quota. Polish sugar industry imports more and more cane sugar for refining which increases the utilization level of its production factors. World prices have had a considerable influence on the domestic prices and thus financial standing of the sector. / Synopsis. W historii gospodarczej świata cukier jest uznawany za jeden z pierwszych produktów globalnych, a sytuacja podażowo-popytowa na światowym rynku miała duży wpływ na rozwój rynków lokalnych. Polski sektor cukrowniczy od wielu lat pozostaje pod wpływem rynku światowego. Reforma systemu regulacji rynku cukru w UE spowodowała, że rynek unijny i krajowy w coraz większym stopniu są uzależnione od sytuacji na rynku światowym. Potencjał produkcyjny krajowego przemysłu cukrowniczego jest większy od zapotrzebowania na rynku wewnętrznym i nadwyżki podaży są kierowane na eksport. Równocześnie system regulacji rynku powoduje, że 200 tys. t cukru musi być importowane, aby pokryć różnicę między zapotrzebowaniem i kwotą produkcyjną. Polski przemysł cukrowniczy importuje coraz większe ilości trzcinowego cukru surowego do rafinacji, która umożliwia lepsze wykorzystanie czynników produkcji. Ceny rynku światowego wyraźnie wpływały na ceny zbytu w kraju i wyniki finansowe sektora.
Tunable Kondo screening length at a Y-junction of three inhomogenous spin chains

description: We derive the topological Kondo Hamiltonian describing a Y junction of three XX-spin chains connected to outer quantum Ising chains with different tilting angles for the Ising axis. We show that the tilting angles in the spin models play the role of the phases of the superconducting order parameters at the interfaces between bulk superconductors and one-dimensional conducting normal electronic wires. As a result, different tilting angles induce nonzero equilibrium spin (super)currents through the junction. Employing the renormalization group approach to the topological Kondo model, we derive the scaling formulas for the equilibrium spin currents. We argue that, by monitoring the crossover in the currents induced by the Kondo effect, it is possible to estimate the Kondo screening length. In particular, we prove how it is possible to tune the Kondo length by acting on the applied phases only; this enables us to map out the scaling properties by just tuning the tilting angles and the Kondo length accordingly.

Nonequilibrium critical dynamics in inhomogeneous systems

description: We study nonequilibrium dynamical properties of inhomogeneous systems, in particular at a free surface or at a defect plane. Thereby we consider nonconserved (model-A) dynamics of a system which is prepared in the high-temperature phase and quenched into the critical point. Using Monte Carlo simulations we measure single spin relaxation and autocorrelations, as well as manifold autocorrelations and persistence. We show that, depending on the decay of critical static correlations, the short time dynamics can be of two kinds. For slow decay of local correlations the usual domain growth process takes place with non-stationary and algebraic dynamical correlations. If, however, the local correlations decay sufficiently rapidly we have the so called cluster dissolution scenario, in which case short time dynamical correlations are stationary and have a universal stretched exponential form. This latter phenomenon takes place in the surface of the three-dimensional Ising model and should be observable in real ferromagnets.

description: Interaction behaviour of an anticancer drug, saracatinib (SCB) with human serum albumin (HSA), the major carrier protein in human blood circulation was investigated using fluorescence and absorption spectroscopy as well as computational methods. Analysis of the fluorescence quenching data along with absorption results confirmed the complex formation between SCB and HSA, based on the inverse correlation of the Stern-Volmer constant (KSV) with temperature and hyperchromic effect in the absorption spectra. Moderate binding affinity between SCB and HSA was evident from the binding constant, Ka value (1.08–0.74 × 104 M−1), while the SCB−HSA complexation was anticipated to be stabilized by hydrophobic and van der Waals interactions along with hydrogen bonds, as revealed from the thermodynamic data (ΔS = + 29.40 J mol−1 K−1 and ΔH = − 13.90 kJ mol−1). Addition of SCB to HSA significantly defended the thermal denaturation of the protein, though it perturbed the surrounding medium around Tyr and Trp residues. Site marker displacement results elucidated Sudlow’s site I, positioned in subdomain IIA of HSA as the preferred binding site of SCB, which was well supported by molecular docking. Molecular dynamics simulation results suggested the stability of the SCB–HSA complex. Communicated by Ramaswamy H. Sarma
title: Development and optimization of a biosensor device based on microwave split-ring resonators
Creators: name: Wagner, Lisa-Marie
Publisher: name: TU Wien
Year: 2017
Subjects: subject: Biosensor
subject: split ring resonator
subject: finite element modeling

description: This thesis is about split-ring resonators and their application as biosensors. Split ring resonators are a special resonator type which consists of a metallic loop etched on a dielectric substrate. They provide a resonant frequency which is determined by the electromagnetic parameters of the substrate and the geometry of the metallic loop. For sensor applications, the metallic surface will be bio-functionalized and if molecules are attaching onto the resonator surface the resonant frequency of the resonator is changed proportional to the load of biomolecules. The aim of the thesis is to optimize the design of different split-ring resonators to get a high-quality biosensor. The operating frequency of the investigated split-ring resonators is between 1.5 and 2.5GHz.

description: Using the exact Bethe ansatz solution of the Hubbard model and Luttinger liquid theory, we investigate the density profiles and collective modes of one-dimensional ultra-cold fermions confined in an optical lattice with a harmonic trapping potential. We determine a generic phase diagram in terms of a characteristic filling factor and a dimensionless coupling constant. The collective oscillations of the atomic mass density, a technique that is commonly used in experiments, provide a signature of the quantum phase transition from the metallic phase to the Mott-insulator phase. A detailed experimental implementation is proposed.
