description: We have studied the local critical current density, jc, in the superconductor thin film of bilayer structures consisting of YBa2Cu3O7 and the ferromagnets La2/3Ca1/3MnO3 and SrRuO3, respectively, by means of quantitative magneto-optics. A pronounced hysteresis of jc was observed which is ascribed to the magnetization state of the ferromagnetic layer. The results are discussed within the frame of magnetic vortex - wall interactions.

description: Research on Helly-type theorems in combinatorial convex geometry has produced volumetric versions of Helly's theorem using witness sets and quantitative extensions of Doignon's theorem. This paper combines these philosophies and presents quantitative Helly-type theorems for the integer lattice with axis-parallel boxes as witness sets. Our main result shows that, while quantitative Helly numbers for the integer lattice grow polynomially in each fixed dimension, their variants with boxes as witness sets are uniformly bounded. We prove several colorful and fractional variations on this theorem. We also prove that the Helly number for $A \times A \subseteq \mathbb{R}^2$ need not be finite even when $A \subseteq \mathbb{Z}$ is a syndetic set.

description: We examine the effects of long-range dipolar forces on metamagnetic transitions and generalize the theory of Condon domains to the case of an itinerant electron system undergoing a first-order metamagnetic transition. We demonstrate that within a finite range of the applied field, dipolar interactions induce a spatial modulation of the magnetization in the form of stripes or bubbles. Our findings are consistent with recent observations in the bilayer ruthenate Sr$_3$Ru$_2$O$_7$.

description: We have studied 116 bright galaxies from the Coma cluster brighter than $m_{r}=17$ mag. From a quantitative morphological analysis we find that the scales of the disks are smaller than those of field spiral galaxies. There is a correlation between the scale of the disks and the position of the galaxy in the cluster; no large disks are present near the center of the cluster or in high density environments. The structural parameters of the bulges are not affected by the environment. We have analyzed the distribution of blue and red objects in the cluster. For spirals there is a trend between color and position in the cluster. The bluest spiral galaxies are located at larger projected radii; they also show larger velocity dispersions than the red ones. The differences in the scale of the disks between cluster galaxies and local samples of isolated galaxies and the color distribution of the objects can be understood in terms of the harassment scenario.

description: Let $f$ and $g$ be two Hecke-Maass cusp forms of weight zero for $SL_2(\mathbb Z)$ with Laplacian eigenvalues $\frac{1}{4}+u^2$ and $\frac{1}{4}+v^2$, respectively. Then both have real Fourier coefficients say, $λ_f(n)$ and $λ_g(n)$, and we may normalize $f$ and $g$ so that $λ_f(1)=1=λ_g(1)$. In this article, we first prove that the sequence $\{λ_f(n)λ_g(n)\}_{n \in \mathbb{N}}$ has infinitely many sign changes. Then we derive a bound for the first negative coefficient for the same sequence in terms of the Laplacian eigenvalues of $f$ and $g$.

description: We present the optical spectra and simple statistical analysis for a complete sample of 110 soft X-ray selected AGN. About half of the sources are Narrow-Line Seyfert 1 galaxies (NLS1s), which have the steepest X-ray spectra, strongest FeII emission and slightly weaker [OIII]5007 emission than broad line Seyfert 1s (BLS1s). Kolmogorov Smirnov tests show that NLS1s and BLS1s have clearly different distributions of the X-ray spectral slope, X-ray short-term variability, and FeII equivalent widths and luminosity and FeII/H-beta ratios. The differences in the [OIII]/H-beta and [OIII] equivalent widths are only marginal. We found no significant differences between NLS1s and BLS1s in their rest frame 0.2-2.0 X-ray luminosities, rest frame 5100A monochromatic luminosities, bolometric luminosities, redshifts, and their H$β$ equivalent widths.

Ex vivo expansion of hematopoietic stem cells for use in nonmyeloablative transplantation
Creators: name: Bakovic, Silvia
Publisher: name: University of British Columbia
Year: 2011

description: Hematopoietic stem cell transplantation (HSCT) is used to treat a wide range of hematologic and non-hematologic disorders. Recently, interest has grown in the potential of autologous HSCT coupled to gene therapy for the treatment of genetic blood disorders as a way of avoiding the severe immunologic reactions associated with allogeneic HSCT. However, the remaining risks in using myeloablative conditioning regimens to allow relatively small numbers of transplanted HSCs to be transplanted greatly limit the applicability of this approach. Nonmyeloablative regimens would be an appealing alternative but necessitate the generation of large numbers of genetically corrected HSCs to achieve therapeutic levels of chimerism. In this thesis I have explored the potential of forced overexpression of homeobox genes as a strategy to obtain the degree of HSC expansion required. In a first series of experiments, I found that HOXB4 and NUPHOX transduced and expanded HSCs maintain the ability of fresh HSCs to produce sustained, high level, polyclonal, lympho-myeloid chimerism when transplanted into mice given 2-2.5 Gy. I then tested the therapeutic efficacy of ex vivo expanded HSCs in nonmyeloablated mice with severe β-thalassemia caused by the homozygous deletion of the β-major globin gene (β-MDD). The results of these experiments showed that this approach could produce a dramatic improvement in the hematocrit, hemoglobin and RBC morphology and ultimately the cure of the thalassemic phenotype that was not achievable in recipients of equivalent numbers of unmanipulated BM cells or of cells transplanted immediately after transduction. Again, the cured mice displayed a sustained, high level of polyclonal chimerism. Together these data provide "proof of principle" of the curative potential of ex vivo expanded HSCs in a preclinical model of β-thalassemia treated with nonmyeloablative conditioning.

High-Redshift Gamma-Ray Bursts from Population III Progenitors

Year: 2005

description: Detection of gamma-ray bursts (GRBs) from redshifts z > 7 would open a new window into the earliest epoch of cosmic star formation. We construct separate star formation histories at high redshifts for normal (Pop I and II) stars, and for predominantly massive (Pop III) stars. Based on these separate histories, we predict the GRB redshift distribution to be observed by the {\it Swift} mission. Regardless of whether Pop III progenitors are able to trigger GRBs, we find that a fraction 10% of all bursts detected by {\it Swift} will originate at z > 5. This baseline contribution is due to Pop I/II star formation which must have extended out to high redshifts in rare massive galaxies that were enriched by heavy elements earlier than the typical galaxies. In addition, we consider the possible contribution of Pop III progenitors to the observable GRB rate. Pop III stars are viable progenitors for long-duration GRBs which are triggered by the collapsar mechanism, as long as they can lose their outer envelope through mass transfer to a companion star in a close binary. We find that the likelihood of Pop III binaries to satisfy the conditions required by the collapsar mechanism could be enhanced significantly relative to Pop I/II binaries. If Pop III binaries are common, {\it Swift} will be first observatory to probe Pop III star formation at redshifts z > 7.

description: The peculiar isospin properties of the b -> c cbar s current lead to a rich set of isospin relations for the B -> Dbar(*) D(*) K decays which are presented here. Recent high quality experimental data on the complete set of these decays (22 measurements) are analysed in this context, the isospin relations are tested and the results for the isospin amplitudes are discussed. The comparison between the measured and expected branching fractions yields a new measurement of the ratio of branching fractions Br(Upsilon(4S) -> B+ B-)/Br(Upsilon(4S) -> B0 B0bar)}=0.86 +- 0.13. We finally discuss the implications of our findings for the measurement of sin(2 beta) and cos(2 beta) using these decays.

MIGNEX Handbook Chapter 2 - Key concepts in the migration–development nexus
Creators: name: Carling, Jørgen
Publisher: name: Peace Research Institute Oslo
Year: 2019

description: Many common concepts – including forced migration, root causes, migration decision, and transit migration – carry assumptions that run counter to the analytical ambitions of MIGNEX. Navigating the terminology calls for balancing critical thinking and pragmatism.

Key Takeaways

MIGNEX is expected to help address the ‘root causes’ of migration. However, the concept itself is troubled by a narrow conception of migration as a symptom of problems.

The emphasis on disaggregation in the MIGNEX methodology is reflected in a terminology that lets us pick processes and phenomena apart.

When our audiences use terminology that differs from ours, we should engage with their usage and explain why we take a different approach.

description: Graphene is of interest in the development of next-generation electronics due to its high electron mobility, flexibility and stability. However, graphene transistors have poor on/off current ratios because of the absence of a bandgap. One approach to introduce an energy gap is to use hydrogenation reaction, which changes graphene into insulating graphane with sp3 bonding. Here we show that an electric field can be used to control conductor-to-insulator transitions in microscale graphene via a reversible electrochemical hydrogenation in an organic liquid electrolyte containing dissociative hydrogen ions. The fully hydrogenated graphene exhibits a lower limit sheet resistance of 200 Gohm/sq, resulting in graphene field-effect transistors with on/off current ratios of 10^8 at room temperature. The devices also exhibit high endurance, with up to one million switching cycles. Similar insulating behaviours are also observed in bilayer graphene, while trilayer graphene remains highly conductive after the hydrogenation. Changes in the graphene lattice, and the transformation from sp2 to sp3 hybridization, is confirmed by in-situ Raman spectroscopy, supported by first-principles calculations.

description: The usefulness in control theory of the geometric theory of motion on Lie groups and homogeneous spaces will be shown. We quickly review some recent results concerning two methods to deal with these systems, namely, a generalization of the method proposed by Wei and Norman for linear systems, and a reduction procedure. This last method allows us to reduce the equation on a Lie group $G$ to that on a subgroup $H$, provided a particular solution of an associated problem in $G/H$ is known. These methods are shown to be very appropriate to deal with control systems on Lie groups and homogeneous spaces, through the specific examples of the planar rigid body with two oscillators and the front-wheel driven kinematic car.

description: We assess the role of perceived reference price (PRP) in consumers’ valuations for four different bread types in secondprice Vickrey auctions taking into account the presence of market substitutes. A possible censoring effect of perceived reference price is modeled using a random effects Tobit model with lower and upper thresholds. The estimates are compared to a random effects Tobit model censored at zero only. In contrast to the existing literature, our results indicate that including perceived reference price in upper threshold does not improve the model fit and thus question the role of PRP as an upper limit for auction bids.

description: The suitability of a fibre-optic distributed temperature sensing (DTS) technique for observing atmospheric mixing profiles within and above a forest was quantified, and these profiles were analysed. The spatially continuous observations were made at a 125 m tall mast in a boreal pine forest. Airflows near forest canopies diverge from typical boundary layer flows due to the influence of roughness elements (i.e. trees) on the flow. Ideally, these complex flows should be studied with spatially continuous measurements, yet such measurements are not feasible with conventional micrometeorological measurements with, for example, sonic anemometers. Hence, the suitability of DTS measurements for studying canopy flows was assessed. The DTS measurements were able to discern continuous profiles of turbulent fluctuations and mean values of air temperature along the mast, providing information about mixing processes (e.g. canopy eddies and evolution of inversion layers at night) and up to third-order turbulence statistics across the forest–atmosphere interface. Turbulence measurements with 3D sonic anemometers and Doppler lidar at the site were also utilised in this analysis. The continuous profiles for turbulence statistics were in line with prior studies made at wind tunnels and large eddy simulations for canopy flows. The DTS measurements contained a significant noise component which was, however, quantified, and its effect on turbulence statistics was accounted for. Underestimation of air temperature fluctuations at high frequencies caused 20 %–30 % underestimation of temperature variance at typical flow conditions. Despite these limitations, the DTS measurements should prove useful also in other studies concentrating on flows near roughness elements and/or non-stationary periods, since the measurements revealed spatio-temporal patterns of the flow which were not possible to be discerned from single point measurements fixed in space.
Mean-Variance Portfolio Management with Functional Optimization

Year: 2020
Subjects: subject: Portfolio Management (q-fin.PM)
subject: FOS: Economics and business

description: This paper introduces a new functional optimization approach to portfolio optimization problems by treating the unknown weight vector as a function of past values instead of treating them as fixed unknown coefficients in the majority of studies. We first show that the optimal solution, in general, is not a constant function. We give the optimal conditions for a vector function to be the solution, and hence give the conditions for a plug-in solution (replacing the unknown mean and variance by certain estimates based on past values) to be optimal. After showing that the plug-in solutions are sub-optimal in general, we propose gradient-ascent algorithms to solve the functional optimization for mean-variance portfolio management with theorems for convergence provided. Simulations and empirical studies show that our approach can perform significantly better than the plug-in approach.
Efficient multi-jet merging with the Vincia sector shower

Year: 2020
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We here present an extension of the CKKW-L multi-jet merging technique to so-called sector showers as implemented in the Vincia antenna shower. The bijective nature of sector showers allows for efficient multi-jet merging at high multiplicities, as any given configuration possesses only a single "history", while retaining the accuracy of the CKKW-L technique. Our method reduces the factorial scaling of the number of parton shower histories to a constant of a single history per colour-ordered final state. We show that the complexity of constructing shower histories is reduced to an effective linear scaling with the number of final-state particles. Moreover, we demonstrate that the overall event generation time and the memory footprint of our implementation remain approximately constant when including additional jets. We compare both to the conventional CKKW-L implementation in Pythia and gain a first estimate of renormalisation scale uncertainties at high merged multiplicities. As a proof of concept, we show parton-level predictions for vector boson production in proton-proton collisions with up to nine hard jets using the new implementation. Despite its much simpler nature, we dub the new technique MESS, in analogy to the conventional MEPS nomenclature.

description: We present a survey of all 3CR sources imaged with ISOCAM onboard the Infrared Space Observatory (ISO). For the source, we present spatially integrated mid--infrared (MIR, 5 - 18mic.) fluxes measured from newly calibrated ISOCAM images. In total, we detected 68 AGN of the 3CR catalogue, at redshifts z < 2.5. The one with the highest redshift is 4C+72.26 at z = 3.53. ISOCAM data are combined with other photometric measurements to construct the spectral energy distribution (SED) from optical to radio wavelengths. In order to describe dust emission we apply new radiative transfer models. By varying three parameters, luminosity, effective size and extinction, we obtain a fit to the SED for our objects. In the MIR the hot dust component is mainly due to small grains and PAHs. In the models, a type 1 AGN is represented by a compact dust distribution, the dust is therefore very warm and emission of PAHs is weak because of photo--destruction. In AGNs of type 2, the dust is relatively colder but PAH bands are strong.

Wie in der letzten Nummer des bisherigen »Freiburger Rundbriefs« angekündigt, ist die Neuaufstellung insbesondere geprägt durch thematische Hefte. Nach dem Tode Elie Wiesels am 2. Juli 2016 hat die neue Schriftleitung die Entscheidung getroffen, das erste Heft dem Auschwitz-Überlebenden, Schriftsteller und Friedensnobelpreisträger zu widmen. Beiträge von Wissenschaftler_innen aus Europa, Israel, den USA und Kanada würdigen Leben und Werk Wiesels in umfassender Weise. Ein zweites Kennzeichen der neuen Heftaufstellung ist die Rubrik »Bildung«, in der Prakti - ker_innen aus verschiedenen Praxisfeldern Im - pulse aufzeigen und Unternehmungen beschreiben, die für andere beispielgebend sein sollen. Zusatzmaterialien werden in einem eigenen Bereich auf der im Aufbau befindlichen Homepage der »Zeitschrift für christlich-jüdische Begegnung im Kontext« angeboten. Weitere und wechselnde Rubriken ergänzen das Panorama – in diesem Heft Jüdisch-Christliche Bibellektüre, freie thematisch Beiträge, Aktuelles, Reisebericht, Rezensionen. Die erste Ausgabe spiegelt die internationale Elie-Wiesel-Forschung in ihrer Breite wider, weshalb aus dem ersten Heft eine Doppelnummer geworden ist. Das nächste Heft (Erscheinungstermin Herbst 2017) wid met sich dem christlich-jüdischen Lernen, das auch die Öffnung zum christlich-muslimischen Dialog einschließt. Die weiteren Hefte werden jeweils abhängig vom Thema unterschiedlichen Umfang haben. Wir wünschen den Leser_innen viele gute und gewinnbringende Impulse!

description: Two coal fly ashes (FA), one from Montana semi-bituminous coal, and another from North Dakota lignite, alone or in
combination with bottom ash ( BA) from Montana semi-bituminous coal were tested as plant growth media for the
following plant species: barley (Hordeum vulgare), oats (Avena sativa), rye (Secale cereale), wheat (Triticum aestivum), regreen; a hybrid between wheatgrass (Agropyroncristatum) and winter wheat (Triticum aestivum),and triticale; a hybrid between wheat (Triticum aestivum) and rye (Secalecereale). The concentration of Cr, in coal ashes and in plant seedlings was determined using Inducted Coupled Plasma Spectrophotometry (ICP). All tested plant species germinated and grew in FA and/or FA + BA containing media. Our data demonstrate that tested plants can grow on media consisting of coal ash, and therefore these plants can be used to cover FA or BA residue piles. The presence of sphagnum peat moss
(SPM) and soil(S) in coal ash based plant growth media expressed ameliorative role by reducing the presence of Cr in plant growth media and in plant seedlings grown on these media.The addition of SPM and S to coal ash based plant
growth media did not lead into the decrease of the presence of Cr in the leachates from media containing SPM or S added to coal ash. Elevated concentrations of Cr in the leachates from FA based plant growth media may cause some environmental health concerns and require further investigations.

description: Urban sprawl is one of the most important reasons behind conflicts over farmland use. In that context, agricultural policy can be perceived as a guardian protecting farmland for agricultural purposes. The paper aims at investigating the role of the Common Agricultural Policy (CAP) in shaping farmland market in Poland. With use of regional Computable General Equilibrium (CGE) model we found out that CAP has led to farmland price distortions in most Polish regions but at the same time it has allowed to maintain land in agricultural use particularly in regions which heavily depend on agriculture and have fragmented farm structure.
Prediction of the Reactivity of Argon with Xenon under High Pressure

description: Pressure significantly modifies the microscopic interactions in condense phase, leading to new patterns of bonding and unconventional chemistry. Both argon and xenon possess closed-shell electronic structures, which renders them chemically unreactive. Using unbiased structure searching techniques combined with first-principles calculations, we demonstrate the reaction of argon with xenon at a pressure as low as 1.1 GPa, producing a novel van der Waals compound XeAr2, which crystallizes in the MgCu2-type Laves phase structure. Due to the pressure-induced delocalization of the electrons in outermost shells, the covalent Xe-Xe and Xe-Ar bonds have been detected which lead XeAr2 to be unexpectedly stable without any phase transition or decomposition at least up to 500 GPa.

description: Improved methods of knowledge acquisition of learners concern direct and indirect actors in the education system; this requires first to know the conception of learners of a given concept. The objective of this paper is to analyze the representations of the learner’s props concept of digestion, a sample of 408 students, was analyzed. We found that most learners still keep the initial representation despite learning concept in 2nd year and 3rd year college and the passage from a level to another. Therefore we could give some explanation to this problem: Maybe teachers do not take into account its initial representations, they remain uncorrected nevertheless learners keep "false” representations for digestion; for example Tubing continues digestive tract, the overvaluation of the stomach …. and the vast majority did not assimilate the concept of digestion, they ignore or they have a remarkable lack of knowledge about the chemical digestion.
 Some students have learned to review and to have good grades.  Some teachers neglect the practical side which is very important in science education and serves to fix the concepts in learners.

description: Repositioning of recording electrode array across repeated electromyography measurements may result in a displacement error in hand movement classification systems. In order to examine if the classifier re-training could reach satisfactory results when electrode array is translated along or rotated around subject's forearm for varying number of features, we recorded surface electromyography signals in 10 healthy volunteers for three types of grasp and 6 wrist movements. For feature extraction we applied principal component analysis and the feature set size varied from one to 8 principal components. We compared results of re-trained classifier with results from leave-one-out cross-validation classification procedure for three classifiers: LDA (Linear Discriminant Analysis), QDA (Quadratic Discriminant Analysis), and ANN (Artificial Neural Network). Our results showed that there was no significant difference in classification accuracy when the array electrode was repositioned indicating successful classification re-training and optimal feature set selection. The results also indicate expectedly that the number of principal components plays a key role for acceptable classification accuracy ~90 %. For the largest dataset (9 hand movements), LDA and QDA outperformed ANN, while for three grasping movements ANN showed promising results. Interestingly, we showed that interaction between electrode array position and the feature set size is not statistically significant. This study emphasizes the importance of testing the interaction of factors that influence classification accuracy and classifier selection altogether with their impact independently in order to establish guiding principles for design of hand movement recognition system. Data recorded for this study are stored on Zenodo repository (doi: 10.5281/zenodo.4039550).

description: We use high-frequency scanner data to estimate product-specific price transmission elasticities across product types, between national brands and private labels and across retail chains in the UK. The results provide new insights into the determinants of price transmission including the role of vertical control in the retail chain, the elasticity of retail mark-ups and retailer market power. Using data on 106 orange juice products over 130 weeks for 7 UK retail chains, we highlight significant variation in price transmission bychain and that the characteristics of pricing behaviour and differences in vertical control across are important determinants of price transmission.

description: Although the Hall coefficient R_H is an informative transport property of metals and semiconductors, its meaning in the cuprate superconductors has been ambiguous because of its unusual characteristics. Here we show that a systematic study of R_H in La_{2-x}Sr_{x}CuO_{4} single crystals over a wide doping range establishes a qualitative understanding of its peculiar evolution, which turns out to reflect a two-component nature of the electronic structure caused by an unusual development of the Fermi surface recently uncovered by photoemission experiments.
