Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We explore the theory of electrons confined by one dimensional power law potentials. We calculate the density profile in the high density electron gas, the low density Wigner crystal, and the intermediate regime. We extract the momentum space wavefunction of the electron at the Fermi surface, which can be measured in experiments on tunneling between parallel wires. The onset of localization leads to a dramatic broadening of the momentum space wavefunction together with pronounced sharpening (in energy) of the tunneling spectrum.

description: Qudit is a multi-level computational unit alternative to the conventional 2-level qubit. Compared to qubit, qudit provides a larger state space to store and process information, and thus can provide reduction of the circuit complexity, simplification of the experimental setup and enhancement of the algorithm efficiency. This review provides an overview of qudit-based quantum computing covering a variety of topics ranging from circuit building, algorithm design, to experimental methods. We first discuss the qudit gate universality and a variety of qudit gates including the pi/8 gate, the SWAP gate, and the multi-level-controlled gate. We then present the qudit version of several representative quantum algorithms including the Deutsch-Jozsa algorithm, the quantum Fourier transform, and the phase estimation algorithm. Finally we discuss various physical realizations for qudit computation such as the photonic platform, iron trap, and nuclear magnetic resonance.

description: The empirical phenomenon that in monopolized markets technological improvements are small compared to competitive markets is to be examined. The level of technological advancements has been measured by how big improvement a new technology represents compared to the current best technology used in the market. The relationship between intensity of competition and technological progress has been examined in a model where R&D laboratory exerts effort, which is translated into a new technology, such that its profits are maximized. It is shown that intensity of competition affects the amount of technological progress in a non-monotone way.
Description of Gluon Propagation in the Presence of an A^2 Condensate

Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: There is a good deal of current interest in the condensate A^2 which has been seen to play an important role in calculations which make use of the operator product expansion. That development has led to the publication of a large number of papers which discuss how that condensate could play a role in a gauge-invariant formulation. In the present work we consider gluon propagation in the presence of such a condensate which we assume to be present in the vacuum. We show that the gluon propagator has no on-mass-shell pole and, therefore, a gluon cannot propagate over extended distances. That is, the gluon is a nonpropagating mode in the gluon condensate. In the present work we discuss the properties of both the Euclidean-space and Minkowski-space gluon propagator. In the case of the Euclidean-space propagator we can make contact with the results of QCD lattice calculations of the propagator in the Landau gauge. With an appropriate choice of normalization constants, we present a unified representation of the gluon propagator that describes both the Minkowski-space and Euclidean-space dynamics in which the A^2 condensate plays an important role.

description: We discuss the consistency of the D=11 supermembranes with non zero central charge arising from a nontrivial winding CSNW. The spectrum of its regularized Hamiltonian is discrete and its heat kernel in terms of a Feynman formula may be rigorously constructed. The $N\to\infty$ limit is discussed. Since CSNW is equivalent to a noncommutative supersymmetric gauge theory on a general Riemann surface, its consistency provides a proof that all of them are well defined quantum theories. We interpret the supermembrane with central charge $n$, in the type IIA picture, as a bundle of D2 branes with $n$ units of D0 charge induced by a nonconstant magnetic flux.

description: We study the dynamics of a circadian oscillator model which was proposed by Tyson, Hong, Thron and Novak. This model indicates a molecular mechanism for the circadian rhythm in Drosophila. After giving a detailed study of the equilibria, we further investigate the effects of the rates of mRNA degradation and synthesis. When the rate of mRNA degradation is rather fast, we prove that there are no periodic orbits in this model. When the rate of mRNA degradation is slow enough, this model is transformed into a slow-fast system. Then based on the geometric singular perturbation theory, we prove the existence of canard explosion, relaxation oscillations, homoclinic/heteroclinic orbits and saddle-node bifurcations as the rates of mRNA degradation and synthesis change. Finally, we give the biological interpretation of the obtained results and point out that this model can be transformed into a Liénard-like equation, which could be helpful to investigate the dynamics of the general case.

Transition in the Acid-Base Component of Surface Free Energy of Ice upon the Premelting of its Second Molecular Bilayer

description: Molecular disordering of the ice surface occurs below the bulk melting temperature of 273 K, termed surface premelting. The top-most molecular layer begins gradually premelting at 200 K, and has been linked to its low coefficient of friction through an increase in molecular mobility. The second molecular bilayer premelts around 257 K, but no study has linked this transition to a change in any macroscopic phenomena. Here, we show that the thermodynamic work of adhesion between polydimethylsiloxane (PDMS) and ice changes abruptly at 257.0 $\pm$ 0.1 K. Surface-sensitive sum frequency generation spectroscopy shows that there are no molecular level changes at the PDMS surface or the ice-PDMS interface near the transition in adhesion, indicating that the transition arises from changes of the ice surface. Using existing contact angle data in the literature, we show that this transition is due to a decrease in the acid-base component of the surface free energy of ice by 17 $\pm$ 2 mJ/m$^2$ at 257.0 $\pm$ 0.1 K. The change in surface energy provides a possible explanation for a variety of unexplained phenomena seen across the literature including ice adhesion, friction, and the morphology of snowflakes.

description: The response of pumpkin, Cucurbita moschata (Duchesne) Poir, to four évapotranspiration replenishment treatments (25, 50, 75, and 100%) was studied at Lajas and Juana Diaz experiment station of the University of Puerto Rico. Pumpkin was planted on 1 March and 17 March, 2000 at Lajas and Juana Diaz, respectively. The experiment was arranged on a split plot, where the whole plot consisted of the évapotranspiration replenishment treatments (ERT) and subplots of drymatter and leaf area determination. Theoretical potential évapotranspiration (ETo) was estimated using the Pan A evaporation method. The average Kp values used were 0.63 and 0.66 for Juana Diaz and Lajas respectively. Pumpkin (var. Soler) average Kc value was 0.78. ERT did not affect significantly crop leaf area, drymatter, and yield at both locations. The lack of response to treatments was due to the high amount of off-season rainfall that occurred during the trial.

description: We develop the first parallel graph coloring heuristics with strong theoretical guarantees on work and depth and coloring quality. The key idea is to design a relaxation of the vertex degeneracy order, a well-known graph theory concept, and to color vertices in the order dictated by this relaxation. This introduces a tunable amount of parallelism into the degeneracy ordering that is otherwise hard to parallelize. This simple idea enables significant benefits in several key aspects of graph coloring. For example, one of our algorithms ensures polylogarithmic depth and a bound on the number of used colors that is superior to all other parallelizable schemes, while maintaining work-efficiency. In addition to provable guarantees, the developed algorithms have competitive run-times for several real-world graphs, while almost always providing superior coloring quality. Our degeneracy ordering relaxation is of separate interest for algorithms outside the context of coloring.

description: Frequently, farmers in Puerto Rico complain that the tuberous roots from the recommended varieties differ in size, shape and weight, a situation that increases difficulties for marketing. Baseline information on the magnitude of losses related to inappropriate root size is not available. The objective was to assess roots' fresh weight distribution among varieties of sweetpotato of common use in Puerto Rico. Four varieties were grown in a location on the southern coastal valley. For this study roots harvested at 162 days were selected. Roots were weighed individually. Distribution of the individual root fresh weight for each variety was compared to theoretical distributions by using the Kolmogorov-Smimov Test. There was a high frequency of light-weighted roots. The Normal Distribution does not describe adequately the data for root fresh weight distribution from any of the varieties. Because of a high frequency of roots having lightweight, Lognormal and Weibull Distributions appear more adequate than the Normal Distribution to describe the actual root weight distribution. Roots end to be too small for the market, thus for commercial purposes, results stress that a relatively high percentage of photosynthates accumulated in the roots are lost. More emphasis on the selection for this characteristic is needed.

description: This paper analyzes a security market with sequential trade and a specialist dealer. I study how heterogeneous Bayes-rational agents with private signals interact if allowed to decide multiple times. I show that in this setting, informational cascades can occur. That is, all agents choose to follow public information over their private signal. I introduce a shortselling constraint on the dealer side, i.e. finite supply of the traded asset. When this constraint binds, cascades can be terminated endogenously in the model.
Role of the novel tumor suppressor p33ING2 in cellular stress response to ultraviolet irradiation in melanoma cells
Creators: name: Wang, Jing
Publisher: name: University of British Columbia
Year: 2010

description: P33ING2 is a candidate tumor suppressor, which shares 58.9% homology with p33ING1b, the founding member of the inhibitor of growth (ING) family, and has been shown to be involved in the regulation of gene transcription, cell cycle arrest and apoptosis in a p53-dependent manner for maintaining the genomic stability. Previously, we demonstrated that p33ING2 promoted UV-induced apoptosis via activation of both the mitochondria/intrinsic and death-receptor/extrinsic apoptotic pathways upon high UV irradiation. Recently, studies have shown that p33ING2 may complex with acetyltransferase (FAT) or histone deacetylase (HDAC). To further reveal the role of p33ING2 in the cellular stress response to UV irradiation, we hypothesized that p33ING2 may enhance the repair of UV-damaged DNA, similar to its homologue p33INGlb, through facilitating histone acetylation and chromatin modification, which are believed to be essential for gene transcription regulation. Using luciferase reporter assays, overexpression of p33ING2 is shown to significantly enhance nucleotide excision repair of UV-induced DNA damage in melanoma cells in a p53-dependent manner. Furthermore, DNA repair is completely abolished in cells treated with p33ING2 siRNA, suggesting that a physiological level of p33ING2 is required for nucleotide excision repair. In addition, p33ING2 is found to be an essential factor for UV-induced rapid histone H4 acetylation, chromatin relaxation, and the recruitment of damage recognition protein XPA to the photolesions. These observations suggest that p33ING2 is required for initial DNA damage sensing and chromatin remodeling in the nucleotide excision repair process. As a member of the ING family, p33ING2 contains a number of highly conserved regions with other ING members, including the plant homeodomain (PHD), leucine zipper-like domain (LZL), and potential chromatin regulatory domain (PCR). Previous studies focused on PHD region of ING proteins since it complexes with histone acetyltransferase (HAT) in its yeast homologue. However, the specific biological functions of other motifs are poorly understood. In this study, using a panel of p33ING2 deletion mutants, we performed functional analyses of different domains of p33ING2. We found that the LZL domain is critical for a functional p33ING2 in both UV-induced DNA repair and apoptosis. In summary, the evidence presented in this thesis that p33ING2 plays an essential role in DNA repair, apoptosis and chromatin remodeling strongly supports the notion that p33ING2 acts as a tumor suppressor.

Subjects: subject: directed search
subject: savings
subject: general equilibrium

description: A general equilibrium model with incomplete markets and directed search is developed, in order to analyze the optimal behavior of workers and comparative statics. Workers have per-period utility of the constant absolute risk aversion (CARA) type. The only form of saving is investment in vacancy creation, which connects the interest rate and job creation through the free entry condition. Because of the CARA utility, all unemployed workers search in the same submarket regardless of their wealth. The optimal saving decisions also make it possible to dene the equilibrium solely in aggregate variables without the distribution of asset levels. The model is calibrated and the existence and uniqueness of the steady state are shown for the specic parameter settings. The eects of a one-percent increase in productivity are examined. The most surprising result is that the interest rate decreases. This is caused by the fact that almost all of the increase in the value of a lled job is oset by the increase in the equilibrium wage and the lower job-lling probability decreases the expected return on a unit of savings and hence, by the free entry condition, the interest rate has to fall.

description: Killing-Yano tensors are natural generalizations of Killing vectors to arbitrary rank anti-symmetric tensor fields. It was recently shown that Killing-Yano tensors lead to conserved gravitational charges, called Y-ADM charges. These new charges are interesting because they measure, for example, the mass density of a p-brane, rather than the total ADM mass which may be infinite. In this paper, we show that the spinorial techniques used by Witten, in his proof of the positive energy theorem, may be straightforwardly extended to study the positivity properties of the Y-ADM mass density for p-brane spacetimes. Although the resulting formalism is quite similar to the ADM case, we show that establishing a positivity bound in the higher rank Y-ADM case requires imposing a condition on the Weyl tensor in addition to an energy condition. We find appropriate energy conditions for spacetimes that are conformally flat or algebraically special, and for spacetimes that have an exact Killing vector along the brane. Finally we discuss our expression for the Y-ADM mass density from the Hamiltonian point of view.

description: Focusing on the twist angle for the minimal commensurate structure, we perform nonperturbative calculations of electron dynamics in the twisted bilayer graphene (TBG) under intense laser fields. We show that the TBG exhibits enriched high-harmonic generation that cannot occur in monolayer or conventional bilayers. We elucidate the mechanism of these nonlinear responses by analyzing dynamical symmetries, momentum-resolved dynamics, and roles of interlayer coupling. Our results imply nonlinear "optotwistronics," or controlling optical properties of layered materials by artificial twists.

Single-file diffusion in a bi-stable potential: signatures of memory in the barrier-crossing of a tagged-particle

description: We investigate memory effects in barrier-crossing in the overdamped setting. We focus on the scenario where the hidden degrees of freedom relax on exactly the same time scale as the observable. As a prototypical model, we analyze tagged-particle diffusion in a single file confined to a bi-stable potential. We identify the signatures of memory and explain their origin. The emerging memory is a result of the projection of collective many-body eigenmodes onto the motion of a tagged-particle. We are interested in the "confining" (all background particles in front of the tagged-particle) and "pushing" (all background particles behind the tagged-particle) scenarios for which we find non-trivial and qualitatively different relaxation behaviors. Notably and somewhat unexpectedly, at a fixed particle number, we find that the higher the barrier, the stronger the memory effects are. The fact that the external potential alters the memory is important more generally and should be taken into account in applications of generalized Langevin equations. Our results can readily be tested experimentally and may be relevant for understanding transport in biological ion-channels.

description: Graphene - transition metal phthalocyanine (G-MPc) hybrid systems constitute promising platforms for densely-packed single-molecule magnets (SMMs). Here, we selected iron(II) phthalocyanine (FePc) and investigated its interaction with pristine and defective graphene layers employing density functional theory. Our calculations indicate that thorough proper dehydrogenation of the benzol rings in the FePc molecule its adsorption to graphene is thermodynamically favorable. In general, the presence of anchoring sites on the graphene layer, i.e. point defects, additionally facilitates the adsorption of FePc, allowing one to achieve high density of SMMs per unit area. Using the combination of group theory, ligand field splitting, and the calculated PBE0 Kohn-Sham eigenvalue spectrum, we resolved the electronic structure and predicted the spin states of both, the isolated FePc and G-FePc hybrid systems. Regardless of adsorption site and the number of removed hydrogen atoms from the benzol rings of FePc, the magnetic moment of the SMM remains unchanged with respect to free FePc. These results should mediate a successful synthesis of densely-packed G-MPc systems and may open up new avenue in designing scalable graphene - SMMs systems for spintronics applications.

Subjects: subject: job-creation
subject: business cycles

description: This thesis uses Austrian social insurance data from 2000 to 2014 to analyze how job creation evolves over the business cycle. For this analysis, firms are split into quintiles according to the median monthly wage earnings of all of their employees, such that one can examine how high paying firms react to a change in the unemployment rate in comparison to low paying firms. For this purpose the net job creation rate or employment growth rate is decomposed into a hire and a separation rate, which are further split into hires from employment and hires from non-employment, likewise for the separations. This makes it possible to examine if high paying firms display stronger pro-cyclical growth, as suggested by the theory of poaching by Moscarini and Postel-Vinay (2012). Yet, results in favor of the wage ladder model cannot be found in general, only for specific samples of the dataset and when particular measures of the business cycle such as the twelve month differences in regional unemployment rates are used, is there evidence in favor of poaching. The novelty of this thesis is the monthly dataset used, which allows to more accurately distinguish between separations to employment and separations to from non-employment, likewise for hires from employment and non-employment, hence making a more detailed analysis of the theory of poaching possible.

For hadronic primaries between proton and iron nuclei, the discrepancy between observed and simulated profiles is in the range of 0.6-1.0 sigma for two different hadronic interaction models investigated. For primary photons, the discrepancy is 1.5sigma assuming a standard extrapolation of the photonuclear cross-section with energy. Larger values of the cross-section at highest energies make primary photon showers more similar to hadron-initiated events. The influence of varying the extrapolation of the photonuclear cross-section is studied.

title: Nonemployment and occupational mobility : life-cycle evidence from the National Longitudinal Survey of Youth

Subjects: subject: nonemployment duration
subject: occupational mobility

description: This thesis uses lifelong labor market histories from the 1979 National Longitudinal Survey of Youth to study how occupational mobility relates to the duration of nonemployment (or jobless) spells. An empirical model which takes into account the duration of all spells experienced by an individual is estimated using Bayesian methods. The main nding is that the timing of the decision to change occupations matters when it comes to jobless spells duration. Those spells which immediately precede an occupation change take longer to exit from. On the other hand, spells beginning after one's rst occupation change have shorter durations. Posterior predictive checks reveal that the model underestimates the dispersion of nonemployment duration which is observed in the data.
The work of art in an age of media saturation : intertextuality and the films of Steven Soderbergh
Creators: name: Wilson, Brenda

description: In the late 1960s, the term "intertextuality" emerged in France in the work of Bulgarian theorist Julia Kristeva. As it was originally conceived, intertextuality was applied primarily to considerations of compare and contrast among texts. Basically, intertextuality pertains to the recognition of the presence of one text in another text. Gradually, as theories of intertextuality developed, the term was expanded to include various forms of cultural production. Text does not only apply to the literary text. All objects of cultural production, particularly electronic arts such as film, can be considered texts. And in more recent films that tend towards postmodern aesthetics, considerations of their intertextuality becomes inevitable. This study will focus on intertextuality as it pertains to the analyses of several films directed by Steven Soderbergh. I will begin by presenting a summary of aspects of intertextuality that pertain to the study of film, particularly theories developed first by Julia Kristeva, and subsequently taken up by theorists such as Roland Barthes and Gerard Genette. This will be followed by a brief introduction to the work of Soderbergh and the recurring features of his oeuvre that facilitate recognition of his auteur status. The argumentation and subsequent conclusions of this thesis will endeavor to demonstrate three points: i) Although intertextuality was originally intended to apply to the study of literature, it is an important term for the study of film. In fact, all contemporary films are intertextual. The work of Steven Soderbergh provides a diverse range of films that facilitate an examination of the appropriateness of using intertextuality as a theoretical framework for the study of cinema. Most contemporary auteurs employ aspects of a postmodern style of filmmaking. One manifestation of postmodernism is the loss of originality, and the difficulty of creating entirely new works of art. But acknowledging the intertextuality of a film need not diminish the value of that film. Recognizing intertextuality as an inevitability should not detract from the auteur status of a given director. Discerning the various sources of Soderbergh's films is a recognition of both his auteur status and his role as less an original author and more an engineer of new film texts based on other artistic and cultural texts evolving from our contemporary, media saturated culture.

description: Question answering (QA) can only make progress if we know if an answer is correct, but current answer correctness (AC) metrics struggle with verbose, free-form answers from large language models (LLMs). There are two challenges with current short-form QA evaluations: a lack of diverse styles of evaluation data and an over-reliance on expensive and slow LLMs. LLM-based scorers correlate better with humans, but this expensive task has only been tested on limited QA datasets. We rectify these issues by providing rubrics and datasets for evaluating machine QA adopted from the Trivia community. We also propose an efficient, and interpretable QA evaluation that is more stable than an exact match and neural methods(BERTScore).

description: El sector agro industrial mexicano enfrenta un mundo complejo con un ritmo revolucionado que lo somete a entornos cambiantes. Los nuevos mercados han incrementado la competencia obligando a la agroindustria nacional a una adaptación con la búsqueda de nuevas alternativas con el desarrollo de estrategias y el firme objetivo de lograr eficiencia en sus procesos, como consecuencia de esto asegurar su permanencia en el mercado. Ante ello ahora las empresas buscan hacer alianzas esenciales para lograr desarrollar su estrategia. Dentro de estas alianzas las empresas agroindustriales buscan participar en el nuevo mercado global con habilidades, recursos, experiencia técnica y capacidades más competitivas logrando reunir con estas alianzas más de lo que pueden aportar cada una por su cuenta. Las alianzas estratégicas hoy en día se han vuelto esenciales para la competitividad que buscan las empresas agroindustriales. Es por ello que surge la inquietud de realizar un análisis detallado para conocer a fondo la técnica de las Alianzas Estratégicas y los acuerdos que esta conlleva, además de sus ventajas y limitantes......The mexican agribusiness sector faces a complex world with a pace that revolutionized subjected to changing environments. New markets have increased competition forcing the national agriculture business to the search for new alternatives to the development of strategies and the firm objective of achieving efficiency in their processes, as a result of this guarantee its permanence on the market. Given this business they’re now looking to make partnerships to develop its strategy. Within these partnerships, agribusiness companies are seeking to participate in the new global market with skills, resources, technical expertise and competitive capabilities. Strategic alliances today have become essential for companies seeking competitive agribusiness. That is why there is the concern of a detailed analysis to fully understand the art of strategic alliances and agreements that this entails, as well as their advantages and limitations.

description: The identification of synthetic routes that end with a desired product has been an inherently time-consuming process that is largely dependent on expert knowledge regarding a limited fraction of the entire reaction space. At present, emerging machine-learning technologies are overturning the process of retrosynthetic planning. The objective of this study is to discover synthetic routes backwardly from a given desired molecule to commercially available compounds. The problem is reduced to a combinatorial optimization task with the solution space subject to the combinatorial complexity of all possible pairs of purchasable reactants. We address this issue within the framework of Bayesian inference and computation. The workflow consists of two steps: a deep neural network is trained that forwardly predicts a product of the given reactants with a high level of accuracy, following which this forward model is inverted into the backward one via Bayes' law of conditional probability. Using the backward model, a diverse set of highly probable reaction sequences ending with a given synthetic target is exhaustively explored using a Monte Carlo search algorithm. The Bayesian retrosynthesis algorithm could successfully rediscover 80.3% and 50.0% of known synthetic routes of single-step and two-step reactions within top-10 accuracy, respectively, thereby outperforming state-of-the-art algorithms in terms of the overall accuracy. Remarkably, the Monte Carlo method, which was specifically designed for the presence of diverse multiple routes, often revealed a ranked list of hundreds of reaction routes to the same synthetic target. We investigated the potential applicability of such diverse candidates based on expert knowledge from synthetic organic chemistry.

description: For any cssc-crossed module a category is constructed, equipped with a structure and proved that this is a coherent categorical group. Together with a result of the previous paper, where to any categorical group the cssc-crossed module is associated, this construction will enable us to prove an equivalence between the categories of categorical groups and of cssc-crossed modules in the sequel to this paper.

description: Dental and hospital staff are at high risk of respiratory diseases that are regularly transmitted by airborne droplets. Patients may not know if they are infected, and of course, in recent days of high LHT delays due to coronavirus, Logistica reported that the American Dental Association (ADA) has developed several recommendations aimed at isolating the flow of patients to prevent LHT knee infection before covid-19 infection. We know that the dental department of a medical institution is aimed at providing assessment services, as well as taking the necessary measures.
