Topological quantum phase transition between Fermi liquid phases in an Anderson impurity model

We study a generalized Anderson model that mixes two localized configurations --one formed by two degenerate doublets and the other by a triplet with single-ion anisotropy $DS_z^2$-- by means of two degenerate conduction channels. The model has been derived for a single Ni impurity embedded into an O-doped Au chain. Using the numerical renormalization group, we find a topological quantum phase transition, at a finite value $D_c,$ between two regular Fermi liquid phases of high (low) conductance and topological number $2 I_L/\pi = 0$ (-1) for $D D_c$), where $I_L$ is the well-known Luttinger integral. At finite temperature the two phases are separated by a non-Fermi liquid phase with fractional impurity entropy $\frac{1}{2}{\rm ln}2$ and other properties which remind those of the two-channel Kondo model.
1 THROUGH THE LOOKING GLASS : Real time 2 imaging in Brachypodium roots and osmotic stress 3 analysis 4 5

To elucidate dynamic developmental processes in plants, live tissues and organs have to 19 be visualized frequently and for long time periods. The development of roots is studied in depth at 20 a cellular resolution not only to comprehend the basic processes fundamental to maintenance and 21 pattern formation but also study stress tolerance adaptation in plants. Despite technological 22 advancements, maintaining continuous access to samples and simultaneously preserving their 23 morphological structures and physiological conditions without causing damage presents 24 hindrances in the measurement, visualization and analyses of growing organs including plant roots. 25 We propose a preliminary system which integrates the optical real-time visualization through light 26 microscopy with a liquid culture which enables us to image at the tissue and cellular level 27 horizontally growing Brachypodium roots every few minutes and up to 24 hours. We describe a 28 simple setup which can be used to track the growth of the root as it grows including the root tip 29 growth and osmotic stress dynamics. We demonstrate the system’s capability to scale down the 30 PEG-mediated osmotic stress analysis and collected data on gene expression under osmotic stress. 31
The Bioenergetic Engine : Muscle Metabolic Properties and Hypermetabolism in ALS

The progressive and fatal loss of upper (brain) and lower (spinal cord) motor neurons and muscle denervation concisely condenses the clinical picture of amyotrophic lateral sclerosis (ALS). Despite the multiple mechanisms believed to underlie the selective loss of motor neurons, ALS aetiology remains elusive and obscure. Likewise, there is also a cluster of alterations in ALS patients in which muscle wasting, body weight loss, eating dysfunction, and abnormal energy dissipation coexist. Defective energy metabolism characterizes the ALS progression, and such paradox of energy balance stands as a challenge for the understanding of ALS pathogenesis. The hypermetabolism in ALS will be examined from tissue-specific energy imbalance (e.g., skeletal muscle) to major energetic pathways (e.g., AMP-activated protein kinase) and whole-body energy alterations including glucose and lipid metabolism, nutrition, and potential involvement of interorgan communication. From the point of view here expressed, the hypermetabolism in ALS should be evaluated as a magnifying glass through which looking at the ALS pathogenesis is from a different perspective in which defective metabolism can disclose novel mechanistic interpretations and lines of intervention.
Obsolescence reduction through product segmentation

The Hershey Company faces a risk of obsolescence across its supply chain as it follows the First In First Out (FIFO) technique at its manufacturing plant distribution center instead of distributing goods based on either the demand at each retailer's end or the useable shelf life of the goods being distributed. The two different stages at which a product can turn obsolete are a) when it reaches expiry and b) during the end of a season or promotion run for a specialty product. The existing picking strategy does not differentiate between orders based on the type of products or the volume served by destination/retailers. This could lead to the risk of obsolescence or return of products in some retailers as the products reach expiry before sales at the retailer's end due to insufficient remaining shelf life. Through this project, we aim at reducing the total obsolescence of a product by proposing a new picking strategy based on the sales volume at each distribution channel and the remaining shelf life of products at the manufacturer's site. The cut-off value or the ratio of volume served by fast moving customer distribution centers to the total volume at which the obsolescence within the supply chain would be minimal was determined for a set of products using an excel simulation model. Hierarchical clustering was performed on all products to form two clusters of distribution centers based on the shipped order quantities and the fractional volume served by both the clusters was determined. The new model was proposed for those product-distribution center combinations with fractional volumes greater than the cut-off as they are most likely to benefit with reduced level of obsoletes.

Social entrepreneurship as a way of developing sustainable township economies

This article investigates using social entrepreneurship as a way of developing sustainabletownship economies, so that poverty can be eradicated from the townships of South Africaand township dwellers can begin to play a role in the economic development of the country.The author also thinks it is God’s purpose for people to enjoy life, free from economic hardship.A reduction in poverty would also bring down the crime rate and other social ills. It starts bydefining and clarifying the concepts of ‘entrepreneur’ and ‘social entrepreneurship’. Itcontinues by looking in more depth into township life and its challenges. This is done throughreviewing the literature and observations obtained through participant observation research.Post-foundationalist practical theology believes in interdisciplinary dialogue as a means ofallowing the concept of social entrepreneurship to bring about a sustainable townshipeconomy. From the author’s observations, it became apparent that to see the attainment of asustainable township economy, training and development should start with a strong emphasison personal identity and interpersonal and business skills. The author, therefore, proposes aholistic approach to social entrepreneurship.
Plasminogen Activator Inhibitor-1 Gene-deficient Mice II

The effects of plasminogen activator inhibitor-l (PAI-1) gene inactivation on hemostasis, thrombosis and thrombolysis were studied in homozygous PAI-i-deficient (PAT-I) mice, generated by homologous recombination in D3 embryonic stem cells. Diluted (10-fold) whole blood clots from PAI-1i-and from PAI-1 wild type (PAI-i 1+) mice underwent limited but significantly different (P < 0.001 ) spontaneous lysis within 3 h (6±1 vs 3±1%, respectively). A 25-A1I '25-fibrin-labeled normal murine plasma clot, injected into a jugular vein, was lysed for 47±5, 66±3, and 87±7% within 8 h in PAI-1 +/+, heterozygous PAT-i-deficient (PA-i +1-), and PAT-i mice, respectively (P = 0.002 for PAI-i 1+ vs PAI-1-imice). Corresponding values after pretreatment with 0.5 mg/kg endotoxin in PA-i +'+ and PAT-Imice, were 35±5 and 91±3% within 4 h, respectively (P < 0.001). 11 out of 26 PA-i +'+ but only 1 out of 25 PAI-1-imice developed venous thrombosis (P = 0.004) within 6 d after injection of 10 or 50 ,ug endotoxin in the footpad. Spontaneous bleeding or delayed rebleeding could not be documented in PA -I mice after partial amputation of the tail or of the caecum. Thus, disruption of the PAI-i gene in mice appears to induce a mild hyperfibrinolytic state and a greater resistance to venous thrombosis but not to impair hemostasis. (J. Clin. Invest. 1993. 92:2756-2760.)

Influence of hypotensive drugs on bone mineral density and fracture risk in patients with arterial hypertension

Nadciśnienie tetnicze wiąze sie z zaburzeniami gospodarki wapniowej. Najcześciej opisywaną nieprawidlowością jest wzmozone wydalanie wapnia z moczem. Hiperkalciuria z kolei moze byc przyczyną zmniejszenia gestości mineralnej kości, a co za tym idzie rowniez wzrostu ryzyka zlaman. Leczenie hipotensyjne moze zapobiegac tym niekorzystnym zjawiskom. Nie jest do konca jasne, ktore grupy lekow hipotensyjnych wykazują najlepszą ochrone. Spodziewac sie mozna interakcji z antagonistami wapnia. Znane są korzystne efekty dzialania diuretykow tiazydowych. Na gospodarke wapniem wplywają takze uklad wspolczulny i uklad renina-angiotensyna-aldosteron. Potencjalnie wiec kazda z grup lekow stosowanych w terapii nadciśnienia tetniczego moze odgrywac role w gospodarce wapniowej. Niniejsza praca przedstawia dotychczasowe wyniki badan wplywu lekow hipotensyjnych na gestośc mineralną kości i ryzyko zlaman.

Implementing Hang Cleans for the Improvement of Vertical Jump in High School Athletes

by Eric C. Scherfenberg The focus of this study was to determine if adding hang clean (HC) to a structured weight training program can make an improvement in vertical jump (VJ). High school student athletes (N=173), were randomly assigned to three groups that all performed the same secondary lifts. The control group (SQG) performed six sets of squat (SQ). Another group performed three sets of HC and three sets of SQ (CSG). The remaining group performed six sets of HC and no SQ (HCG). Preand post-assessments of VJ were recorded at the beginning and end of the six week study using a Vertec. The study determined a significant difference of average VJ improvement between both the CSG (1.48 inches) and HCG (1.05 inches) when compared to the SQG (.26 inches). There was also a significant difference between the CSG and HCG leading to the recommendation to implement HC equally with SQ to maximize VJ.

Analysis of the relationship between institutional quality, natural resources and economic growth

For a long time there has been a belief that countries with great reserves of natural resources have a great advantage respect to countries with limited natural resources. Nevertheless the present study shows that this abundance and the increasing export of the natural resources does not entail necessarily to an economic growth of “the surpassed” country, instead the abundance would have to be accompanied of an institutional frame of good quality that encourages the interchange and the production in detriment of redistributive activities.

Product variety and the export pattern of Poland 1999-2006

The goal of this article is to investigate the role of product variety and changes in the product variety in the patter of exports of Poland a middle-sized open economy in the second phase of economic transition to a benchmark group of countries – EU15. The analysis covers the period 1999-2006 and is carried out on highly disaggregated trade data. In the analysis we utilize both simple index of variety of products as well as an index of relative variety of products. Attention is given to the scope and structure of intra-industry trade. The overall product variety in exports to EU15 as measured by simple product counts is found to have decreased while relative product variety in comparison to EU15 Member States remained at roughly unchanged level. Furthermore we investigate the link between the changes in export variety and the growth of TFP in Polish manufacturing industry sectors. The conclusions are drawn from dynamic panel data model controlling for several features suggested by the literature of the subject. The results are rather intriguing and need further robustness tests.
The Hurricane—Climate Connection

Abstract Tropical cyclone activity has long been understood to respond to changing properties of the large-scale atmospheric and oceanic environment. In this essay, evidence for changing tropical cyclone activity is reviewed, and the controversy surrounding the quality of the data itself and the attribution of these environmental changes to various natural and anthropogenic causes, is discussed. At the same time, there is growing evidence that global tropical cyclone activity may itself affect climate in such a way as to mitigate tropical climate change but amplify climate change at higher latitudes. This evidence is reviewed, and possible routes forward in exploring these effects are suggested.
International Equity Market Integration in a Small Open Economy: Ireland January 1990 - December 2000

We examine the relationship between the Irish, German, UK and US equity markets. Our main finding is that the Irish equity market depends heavily on trading activity in the other markets but not vice versa. Significant return and volatility spillover effects occur in the direction of, but not from the Irish market. We also find that dual listing in the form of ADRs has an important role to play in these spillover effects. Our findings obtain throughout the sample, but are strongest for the period after the ERM crises and before the introduction of the euro.
Container port selection in contestable hinterlands

Port competition has become fiercer with each passing day due to the developments in hinterland networks, port innovations at ports, port privatization policies and the changing specific service expectations of port users. This competitive environment has led to shifting the hinterland areas from captivity to contestability. The customer focus in determining the level of service quality and service diversity is crucial to gain a share from such contestable and competitive hinterlands. Therefore, the main aim of this study is to determine port selection criteria of port users and to develop a model for measuring selection criteria of port users in contestable hinterlands. A confirmatory factor analysis was applied to develop a model for port selection in a contestable hinterland. The model includes 7 main constructs and total 32 criteria. The model reveals that competitiveness of ports in contestable hinterlands is not only affected by ports’ own services but external ones such as number and frequency of shipping lines calling at the port are also vital.
3D OBJECT RECONSTRUCTION FROM NON-GEOREFERENCED MONOCULAR IMAGERY

D object reconstruction from high-resolution aerial photographs and satellite images is one of the most popular applications in mapping. Considerable efforts have been made to extract 3D information by modelling the geometry and the photometry from the imagery of real scenes. The objective of this research is to investigate existing methods and strategies for 3D building reconstruction from high-resolution monocular images, and develop new techniques for non-georeferenced monocular images acquired at varying geometry conditions, including high-resolution aerial photographs, images taken from hand held cameras, and high-resolution satellite images (e.g., IKONOS, QuickBird, and OrbiView). In this paper we investigate the vanishing points based methods for 3D object reconstruction using a monocular oblique aerial image and a synthetic cubic image. The emphasis is placed on the accuracy assessment of the recovered sensor orientation parameters and 3D models reconstructed. The factors influencing the accuracy of this approach are also addressed. We suggested using model based methods for the 3D building reconstruction from monocular images.
Media Exposure and Body Image in 6-9 Year Old Girls: The Role of Perceived Realism and Internalization of Media

Dara R. Musher-Eizenman, Advisor Previous research has established that adult-focused media contributes to poor body image attitudes in adult and teenage women. The body image attitudes of children are also negatively affected by adult-focused media. Although child-focused media contains similar thinfemale idealized messages and themes, the impact of this type of media on the body image attitudes of young girls has not been well studied. This study examined the relationship between 6-9 year old girls’ exposure to child-focused media and their body image attitudes. Internalization of the thin ideal and perceived realism of media were also examined as individual difference variables and their relationship to body image attitudes is reported. No media exposure or preference variables directly impacted participants’ body image attitudes, possibly because reports of media were unreliable. Thin ideal internalization and perceived realism of child-focused media were significantly correlated. Internalization was also related to a preference for a thinner body. Results from this study highlight the need for improved measures of media exposure and the importance of understanding how young girls internalize the thin ideal portrayed in the media.
Using sentiment and social network analyses to predict opening-movie box-office success

In this thesis, we explore notions of collective intelligence in the form of web metrics, social network analysis and sentiment analysis to predict the box-office income of movies. Successful prediction techniques would be advantageous for those in the movie industry to gauge their likely return and adjust preand post-release marketing efforts. Additionally, the approaches in this thesis may also be applied to other markets for prediction as well. We explore several modeling approaches to predict performance on the Hollywood Stock Exchange (HSX) prediction market as well as overall gross income. Some models use only a single movie’s data to predict its future success, while other models build from the data of all the movies together. The most successful model presented in this thesis improves on HSX and provides high correlations/low predictive error on both HSX delist prices as well as the final gross income of the movies. We also provide insights for future work to build on this thesis to potentially uncover movies that perform exceptionally poorly or exceptionally well.

The importance of long‐distance dispersal in biodiversity conservation

Dispersal is universally considered important for biodiversity conservation. However, the significance of long‐ as opposed to short‐distance dispersal is insufficiently recognized in the conservation context. Long‐distance dispersal (LDD) events, although typically rare, are crucial to population spread and to maintenance of genetic connectivity. The main threats to global biodiversity involve excessive LDD of elements alien to ecosystems and insufficient dispersal of native species, for example, because of habitat fragmentation. In this paper, we attempt to bridge the gap in the treatment of LDD by reviewing the conservation issues for which LDD is most important. We then demonstrate how taking LDD into consideration can improve conservation management decisions.
Compressed algebras: Artin algebras having given socle degrees and maximal length

J. Emsalem and the author showed in [18] that a general polynomialf of degree j in the ring SP= k[yl,. ,yr] has (jr+-rl 1) linearly independent partial derivates of order i, for i = 0,1, . , t = [ j/2]. Here we generalize the proof to show that the various partial derivates of s polynomials of specified degrees are as independent as possible, given the room available. Using this result, we construct and describe the varieties G( E) and Z( E) parametrizing the graded and nongraded compressed algebra quotients A = R/I of the power series ring R = k[[xl sXr]] having given socle type E. These algebras are Artin algebras having maximal length dimk A possible, given the embedding degree r and given the socle-type sequence E = ( els . . . s eS), where ei is the number of generators of the dual module A of A, having degree i. The variety Z(E) is locally closed, irreducible, and is a bundle over G(E), fibred by affine spaces AN whose dimension is known. We consider the compressed algebras a new class of interesting algebras and a source of examples. Many of them are nonsmoothable-have no deformation to (k + + k)-for dimension reasons. For some choices of the sequence E, D. Buchsbaum, D. Eisenbud and the author have shown that the graded compressed algebras of socle-type E have almost linear minimal resolutions over R, with ranks and degrees determined by E. Other examples have given type e = dimk (socle A) and are defined by an ideal I with certain given numbers of generators in R =
WORKING PAPER SERIES Financial Frictions , Bubbles , and Macroprudential Policies

We explore the ability of a macroprudential policy instrument to dampen the consequences of equity mispricing (a bubble) and the correction thereof (the bubble bursting), as well as the consequences for real activity in a production economy. In our model, producers are financed by both bank debt and equity, and face a mix of systemic and idiosyncratic uncertainty. Positive/negative bubbles arise when prior public beliefs about the aggregate productivity of producers (business sentiment) become biased upwards/downwards. Economic activity in equilibrium is influenced by the bubble size in conjunction with agency problems caused by delegation of lending to relationship bankers. The presence of macroprudential policy is manifested in a convex dependence of bank capital requirements on the quantity of uncollateralized credit. We find that this kind of policy is more successful in suppressing equity price swings than moderating output fluctuations. At the same time, economic activity recoils substantially with the introduction of a macroprudential instrument, so that its presence is likely to entail tangible welfare costs. In this regard, fine-tuning capital charges as a function of corporate governance on the borrower side (specifically, by discouraging limited liability of borrowing firm managers) would be less costly than placing the full burden of prudential regulation on the lender side.
