description: We address the problem of unambiguous discrimination among oracle operators. The general theory of unambiguous discrimination among unitary operators is extended with this application in mind. We prove that entanglement with an ancilla cannot assist any discrimination strategy for commuting unitary operators. We also obtain a simple, practical test for the unambiguous distinguishability of an arbitrary set of unitary operators on a given system. Using this result, we prove that the unambiguous distinguishability criterion is the same for both standard and minimal oracle operators. We then show that, except in certain trivial cases, unambiguous discrimination among all standard oracle operators corresponding to integer functions with fixed domain and range is impossible. However, we find that it is possible to unambiguously discriminate among the Grover oracle operators corresponding to an arbitrarily large unsorted database. The unambiguous distinguishability of standard oracle operators corresponding to totally indistinguishable functions, which possess a strong form of classical indistinguishability, is analysed. We prove that these operators are not unambiguously distinguishable for any finite set of totally indistinguishable functions on a Boolean domain and with arbitrary fixed range. Sets of such functions on a larger domain can have unambiguously distinguishable standard oracle operators and we provide a complete analysis of the simplest case, that of four functions. We also examine the possibility of unambiguous oracle operator discrimination with multiple parallel calls and investigate an intriguing unitary superoperator transformation between standard and entanglement-assisted minimal oracle operators.

description: The website network of a tourism destination is examined. Network theoretic metrics are used to gauge the static and dynamic characteristics of the webspace. The topology of the network is found partly similar to the one exhibited by similar systems. However, some differences are found, mainly due to the relatively poor connectivity and clusterisation of the network. These results are interpreted by considering the formation mechanisms and the connotation of the linkages between websites. Clustering and assortativity coefficients are proposed as quantitative estimations of the degree of collaboration and cooperation among destination stakeholders.

"From Dragonfly to Butterfly": Nation, Identity and Culture in Postrevolutionary Mexico (1920-1940) as Reflected in Nellie Campobello's Dance and Narrative
Creators: name: De La Calle, Sophie
Publisher: name: Digital Repository at the University of Maryland
Year: 1998

description: This dissertation explores the question of identity in dancer and writer
Nellie Campobello (1900-?) in post-revolutionary Mexico. I examine the evolution
of her dance, her narrative and her poetry in the light of important cultural and
political changes. Because a principal element in this discussion is the formation
of a strong national identity, I have decided to study its effects on both her dance
and her literary works. Part 1 considers the role of the Nation-State in articulating
the postwar-self together with the role of prominent intellectuals such as Jose
Vasconcelos; his impact upon a new cultural and Mexican aesthetic in which myth
___ j
and symbols such as the National Stadium played a decisive role in imagining the
nation. Part 2 explores the dance in the context of the polemical and radical 30s
when Nellie Campobello emerged as a representative of the new aesthetics in
which the "masculine" as opposed to the "feminine" redefined the national
identity. The II stadium dance" and the 11 soldadera" were seen as best expressions
for revolution and socialism in the Cardenas era. The focus of part 3 is the cultural
and aesthetic shift from the radical and the "masculine" to the conciliatory and the
"feminine". With the help of influential fatherly figures such as Martin Luis
Guzman, a past member of the Ateneo de la Juventud, Nellie Campobello adapted
herself to his classical tradition. From this point on this study focuses on literary
texts to discuss her contributions to questions of identity. In part 4 I examine the
formation of identity in the context of the rebelious and iconoclastic thirties
reflected in Campobello's early poetry. I then study Cartucho and its rejections of
myth and its recuperation of the forgotten men and women of the Revolution.
Part 5 returns to the ambivalent relationship between Campobello and Guzman,
sponsor of Campobello's new image. Her strategic alliance with a prestigious
figure of "criollo" culture in the late thirties would help reshape the "coarse"
Cartucho into the "refined" and spiritual image of Las manos de mama.
Consequently, part 6 examines the effects and the consequences of her
metamorphosis from the rebelious and authentic to the ambivalent and more
"domestic" image of the feminine redefined by national myths.

description: We report the design and performance of the hybrid electromagnetic calorimeter consisting of 1152 $PbWO_4$ crystals and 576 lead glass blocks for the PrimEx experiment at the Jefferson Laboratory. The detector was built for high precision measurement of the neutral pion lifetime via the Primakoff effect. Calorimeter installation and commissioning was completed with the first physics run in fall of 2004. We present the energy and position resolution of the calorimeter. Obtained $π^0$ mass resolution of $1.3 \mathrm{MeV/c^2}$ and its production angle resolution of $0.34 \mathrm{mrad}$ demonstrate the ability of the experiment to extract the $π^0$ lifetime on one percent level.

description: The Ra EDM experiment uses a pair of high voltage electrodes to search for the atomic electric dipole moment of $^{225}$Ra. We use identical, plane-parallel electrodes with a primary high gradient surface of 200 mm$^2$ to generate reversible DC electric fields. Our statistical sensitivity is linearly proportional to the electric field strength in the electrode gap. We adapted surface decontamination and processing techniques from accelerator physics literature to chemical polish and clean a suite of newly fabricated large-grain niobium and grade-2 titanium electrodes. Three pairs of niobium electrodes and one pair of titanium electrodes were discharge-conditioned with a custom high voltage test station at electric field strengths as high as $+52.5$ kV/mm and $-51.5$ kV/mm over electrode gap sizes ranging from 0.4 mm to 2.5 mm. One pair of large-grain niobium electrodes was discharge-conditioned and validated to operate at $\pm 20$ kV/mm with steady-state leakage current $\leq 25$ pA ($1σ$) and a polarity-averaged $98 \pm 19$ discharges per hour. These electrodes were installed in the Ra EDM experimental apparatus, replacing a copper electrode pair, and were revalidated to $\pm 20$ kV/mm. The niobium electrodes perform at an electric field strength 3.1 times larger than the legacy copper electrodes and are ultimately limited by the maximum output of our 30 kV bipolar power supply.

description: We study electron transport properties of a monoatomic graphite layer (graphene) with different types of disorder at half filling. We show that the transport properties of the system depend strongly on the symmetry of disorder. We find that the localization is ineffective if the randomness preserves one of the chiral symmetries of the clean Hamiltonian or does not mix valleys. We obtain the exact value of minimal conductivity $4e^2/πh$ in the case of chiral disorder. For long-range disorder (decoupled valleys), we derive the effective field theory. In the case of smooth random potential, it is a symplectic-class sigma model including a topological term with $θ= π$. As a consequence, the system is at a quantum critical point with a universal value of the conductivity of the order of $e^2/h$. When the effective time reversal symmetry is broken, the symmetry class becomes unitary, and the conductivity acquires the value characteristic for the quantum Hall transition.

description: The existence of semiconductors exhibiting long-range ferromagnetic ordering at room temperature still is controversial. One particularly important issue is the presence of secondary magnetic phases such as clusters, segregations, etc... These are often tedious to detect, leading to contradictory interpretations. We show that in our cobalt doped ZnO films grown homoepitaxially on single crystalline ZnO substrates the magnetism unambiguously stems from metallic cobalt nano-inclusions. The magnetic behavior was investigated by SQUID magnetometry, x-ray magnetic circular dichroism, and AC susceptibility measurements. The results were correlated to a detailed microstructural analysis based on high resolution x-ray diffraction, transmission electron microscopy, and electron-spectroscopic imaging. No evidence for carrier mediated ferromagnetic exchange between diluted cobalt moments was found. In contrast, the combined data provide clear evidence that the observed room temperature ferromagnetic-like behavior originates from nanometer sized superparamagnetic metallic cobalt precipitates.

description: We develop and analyze a model for ratchet-driven macroscopic transport of a continuous phase. The transport relies on a field-induced dewetting-spreading cycle of a liquid film with a free surface based on a switchable, spatially asymmetric, periodic interaction of the liquid-gas interface and the substrate. The concept is exemplified using an evolution equation for a dielectric liquid film under an inhomogeneous voltage. We analyse the influence of the various phases of the ratchet cycle on the transport properties. Conditions for maximal transport and the efficiency of transport under load are discussed.

description: Millisecond pulsars are very likely the main source of gamma-ray emission from globular clusters. However, the relative contributions of two separate emission processes--curvature radiation from millisecond pulsar magnetospheres vs. inverse Compton emission from relativistic pairs launched into the globular cluster environment by millisecond pulsars--have long been unclear. To address this, we search for evidence of inverse Compton emission in 8-year $\textit{Fermi}$-LAT data from the directions of 157 Milky Way globular clusters. We find a mildly statistically significant (3.8$σ$) correlation between the measured globular cluster gamma-ray luminosities and their photon field energy densities. However, this may also be explained by a hidden correlation between the photon field densities and the stellar encounter rates of globular clusters. Analysed $\textit{in toto}$, we demonstrate that the gamma-ray emission of globular clusters can be resolved spectrally into two components: i) an exponentially cut-off power law and ii) a pure power law. The latter component--which we uncover at a significance of 8.2$σ$--has a power index of 2.79 $\pm$ 0.25. It is most naturally interpreted as inverse Compton emission by cosmic-ray electrons and positrons injected by millisecond pulsars. We find the luminosity of this power-law component is comparable to, or slightly smaller than, the luminosity of the curved component, suggesting the fraction of millisecond pulsar spin-down luminosity into relativistic leptons is similar to the fraction of the spin-down luminosity into prompt magnetospheric radiation.

description: High resolution UVES spectra of 40 main-sequence stars with -3.3 < [Fe/H] < -1.0 are used to derive S, Fe and Zn abundances from lines in the 400 - 950 nm region. For one star we also present novel observations of the SI triplet at 1.046 micron carried out with the ESO VLT CRIRES spectrograph. Comparison of sulphur abundances from the weak and strong SI lines provides important constraints on non-LTE effects. The high sulphur abundances reported by others for some metal-poor stars are not confirmed; instead, when taking non-LTE effects into account, the Galactic halo stars distribute around a plateau at [S/Fe] = +0.2 dex with a scatter of 0.07 dex only. This indicates that sulphur in Galactic halo stars has been made by alpha-capture processes in massive SNe. The observed scatter in S/Fe is, however, much smaller than predicted from current stochastic models of the chemical evolution of the early Galaxy, suggesting that either the models or the calculated yields of massive SNe should be revised. [Zn/Fe] is close to zero for metallicities in the range -2.0 < [Fe/H] < -1.0 but increases to a level of [Zn/Fe] = +0.15 dex in the range -2.7 < [Fe/H] < -2.0. At still lower metallicities [Zn/Fe] rises steeply to a value around [Zn/Fe] = +0.5 dex at [Fe/H] = -3.2. We also examine the behaviour of S/Zn and find that departures from the solar ratio are significantly reduced at all metallicities if non-LTE corrections to the abundances of these two elements are adopted. This effect, if confirmed, would reduce the usefulness of the S/Zn ratio as a diagnostic of past star-formation activity, but would bring closer together the values measured in damped Lyman-alpha systems and in Galactic stars.

description: We analyze the three-year WMAP temperature anisotropy data seeking to confirm the power spectrum and likelihoods published by the WMAP team. We apply five independent implementations of four algorithms to the power spectrum estimation and two implementations to the parameter estimation. Our single most important result is that we broadly confirm the WMAP power spectrum and analysis. Still, we do find two small but potentially important discrepancies: On large angular scales there is a small power excess in the WMAP spectrum (5-10% at l~300). Recently, the latter discrepancy was explained by Huffenberger et al. (2006) in terms of over-subtraction of unresolved point sources. As far as the low-l bias is concerned, most parameters are affected by a few tenths of a sigma. The most important effect is seen in n_s. For the combination of WMAP, Acbar and BOOMERanG, the significance of n_s =/ 1 drops from ~2.7 sigma to ~2.3 sigma when correcting for this bias. We propose a few simple improvements to the low-l WMAP likelihood code, and introduce two important extensions to the Gibbs sampling method that allows for proper sampling of the low signal-to-noise regime. Finally, we make the products from the Gibbs sampling analysis publically available, thereby providing a fast and simple route to the exact likelihood without the need of expensive matrix inversions.

description: Written against a background of intellectual and social ferment over woman’s nature and role, the eight plays discussed implicitly criticize Renaissance society’s refusal to recognize woman’s full humanity by presenting strong, intelligent heroines seeking personal fulfilment in a hostile culture. For Shakespeare’s Desdemona and Cleopatra, sexuality is an integral part of the love they offer Othello and Antony who, however, stereotypically see women’s sexuality as wantonness and temptation. Iago easily persuades Othello that Desdemona’s independent spirit is a sign of lust. For Antony, Cleopatra’s love is a temptation to political and military indolence. Because her brothers see her remarriage as a taint on family honour, Webster’s Duchess of Malfi must act clandestinely to obtain a sexually and personally fulfilling marriage for which, on its discovery, the brothers take a horrible revenge. Socially ambitious, Vittoria Corombona too seeks sexual fulfilment and resorts to murder to escape an unfulfilling marriage and gain status. For both women, the resort to deception or to evil seems necessary in an evil, corrupt and hostile world which takes its revenge on both. Beaumont’s Evadne uses her sexual power to become the King’s mistress, hoping thereby to escape the social forces that victimize women. She finds herself, however, caught between conflicting codes of honour whose adherents all reject her as a kind of social pariah. Middleton’s Bianca Capello, Isabella and Beatrice-Joanna attempt to escape the tyranny of enforced marriage by elopement, adultery, or murder in a corrupt society, which paying lip service to, but not itself observing conventional morality, passes harsh judgement on them for their breaches of convention. Acceptance of, rather than rebellion against, enforced marriage leads Ford’s Penthea to a pathological brooding which results in her own death and the deaths of the chief characters. Though the five playwrights offer no solutions to their society’s tyranny over women, they strongly imply the need to adopt a more natural and comprehensive paradigm of woman.

description: Στην εργασία αυτή σκοπός ήταν να μελετήσουμε τη θέση της γυναίκας εκπαιδευτικού στις αρχές του 20ου αιώνα (1909-1914). Προηγήθηκε μία εισαγωγή σχετικά με το εκπαιδευτικό σύστημα των γυναικών στον Ελλαδικό χώρο και τις Νέες Χώρες, οι οποίες προσαρτήθηκαν στην Ελλάδα το 1914. Στο κομμάτι αυτό είδαμε το είδος εκπαίδευσης που λάμβαναν οι γυναίκες εκπαιδευτικοί κατά τη διάρκεια του 19ου αιώνα, τις μεταρρυθμίσεις που υφίστατο με το πέρασμα των ετών και τις διαφορές που παρουσίαζε σε σχέση με την εκπαίδευση των αντρών. Το εκπαιδευτικό σύστημα των γυναικών στις προσαρτημένες περιοχές μας απασχόλησε, καθώς με την προσάρτησή τους πολλές γυναίκες από τις περιοχές αυτές απορροφήθηκαν στα ελληνικά σχολεία ως εκπαιδευτικοί. Μελετήθηκαν οι νόμοι που ψηφίζονταν κατά χρονικά διαστήματα και αφορούσαν τον κλάδο αυτό. Όσον αφορά στο ερευνητικό κομμάτι έγινε καταγραφή όλων των γυναικών εκπαιδευτικών που διορίστηκαν τις χρονιές 1909 έως και 1914. Παράλληλα με την καταγραφή των ονομάτων καταγράφηκαν και άλλες πληροφορίες. Αυτές ήταν η ιδιότητα διορισμού της κάθε εκπαιδευτικού, οι σπουδές που είχε κάνει, ο βαθμός διορισμού της, ο μισθός που λάμβανε καθώς και ο τόπος στον οποίο διοριζόταν. Βέβαια, δεν μας δίνονταν όλες αυτές οι πληροφορίες για κάθε διορισμένη εκπαιδευτικό, αλλά κάποιες από αυτές. Στη συνέχεια ακολούθησε σχολιασμός του υλικού και η έκθεση προσωπικών εμπειριών μίας εκπαιδευτικού των εξεταζόμενων ετών.
description: In this work the aim was to study the status of women’s education in the early 20th century (1909-1914). Preceded by an introduction about the educational system of women in Greece and the new Member States, which were annexed to Greece in 1914. In this essay we studied the kind of education that women teachers received during the 19th century, the reforms that took place with the passage of years and the differences presented in relation to the education of men. The educational system of the women at the new Member States has been studied, since many women from these areas were absorbed in Greek schools as teachers. The laws that had to do with women’s education were also discussed. As regards the research piece we wrote down all the names of the female teachers who were appointed in the years 1909 to 1914. Alongside the recording of names, other information were recorded too. These were the appointment of every educational property, the studies that had been done, the grade of appointment, the salary received and the place to which appointed. Of course, we were not given all of this information for every woman, but some of them. What came next were a commentary of the material and the personal experiences of a teacher's report of the studied years.

description: Para contribuir con las acciones recogidas en el Plan Lector del centro, se lleva a cabo “Juntos aprendemos y entre todos mejoramos”. Se trata de un proyecto desarrollado en el CEIP Mare Nostrum de Ceuta, que presenta varias líneas de actuación (alumnado, familias y centro escolar). Para evaluar el alcance del proyecto “Juntos aprendemos y entre todos mejoramos” se ha efectuado un análisis fundamentado en una metodología de investigación mixta, es decir, mediante un estudio de corte cuantitativo y cualitativo. A nivel cuantitativo, se ha realizado un diseño de investigación cuasi-experimental, mediante grupo control y grupo experimental, con pre-test y post-test, de corte descriptivo y correlacional. A nivel cualitativo, se ha desarrollado un estudio de corte fenomenológico, con un diseño de investigación de carácter evaluativo, en el que se identifican los conceptos claves de la inducción, la saturación de datos y la construcción de teorías sustantivas. El estudio se ha efectuado en diversos momentos bien diferenciados: ▪ Septiembre de 2021: 1ª recopilación de datos cuantitativos. ▪ Febrero de 2022: 2ª recopilación de datos cuantitativos y entrevistas a miembros de la administración educativa. ▪ Marzo de 2022: entrevistas a familias. ▪ Mayo de 2022: 3ª recopilación de datos cuantitativos y entrevistas a estudiantes y profesorado.

description: Model compression techniques allow to significantly reduce the computational cost associated with data processing by deep neural networks with only a minor decrease in average accuracy. Simultaneously, reducing the model size may have a large effect on noisy cases or objects belonging to less frequent classes. It is a crucial problem from the perspective of the models' safety, especially for object detection in the autonomous driving setting, which is considered in this work. It was shown in the paper that the sensitivity of compressed models to different distortion types is nuanced, and some of the corruptions are heavily impacted by the compression methods (i.e., additive noise), while others (blur effect) are only slightly affected. A common way to improve the robustness of models is to use data augmentation, which was confirmed to positively affect models' robustness, also for highly compressed models. It was further shown that while data imbalance methods brought only a slight increase in accuracy for the baseline model (without compression), the impact was more striking at higher compression rates for the structured pruning. Finally, methods for handling data imbalance brought a significant improvement of the pruned models' worst-detected class accuracy.

Thermo-statistical description of gas mixtures from space partitions

description: The new mathematical framework based on the free energy of pure classical fluids presented in [R. D. Rohrmann, Physica A 347, 221 (2005)] is extended to multi-component systems to determine thermodynamic and structural properties of chemically complex fluids. Presently, the theory focuses on $D$-dimensional mixtures in the low-density limit (packing factor $η< 0.01$). The formalism combines the free-energy minimization technique with space partitions that assign an available volume $v$ to each particle. $v$ is related to the closeness of the nearest neighbor and provides an useful tool to evaluate the perturbations experimented by particles in a fluid. The theory shows a close relationship between statistical geometry and statistical mechanics. New, unconventional thermodynamic variables and mathematical identities are derived as a result of the space division. Thermodynamic potentials $μ_{il}$, conjugate variable of the populations $N_{il}$ of particles class $i$ with the nearest neighbors of class $l$ are defined and their relationships with the usual chemical potentials $μ_i$ are established. Systems of hard spheres are treated as illustrative examples and their thermodynamics functions are derived analytically. The low-density expressions obtained agree nicely with those of scaled-particle theory and Percus-Yevick approximation. Several pair distribution functions are introduced and evaluated. Analytical expressions are also presented for hard spheres with attractive forces due to Kâc-tails and square-well potentials. Finally, we derive general chemical equilibrium conditions.

description: In almost all quantum applications, one of the key steps is to verify that the fidelity of the prepared quantum state meets expectations. In this Letter, we propose a new approach solving this problem using machine-learning techniques. Compared to other fidelity estimation methods, our method is applicable to arbitrary quantum states, the number of required measurement settings is small, and this number does not increase with the size of the system. For example, for a general five-qubit quantum state, only four measurement settings are required to predict its fidelity with $\pm1\%$ precision in a nonadversarial scenario. This machine-learning-based approach for estimating quantum state fidelity has the potential to be widely used in the field of quantum information.

Constraints on Dark Energy from Galaxy Cluster Gas Mass Fraction versus Redshift data

Year: 2008
Subjects: subject: Astrophysics (astro-ph)

description: We use the Allen et al. (2008) galaxy cluster gas mass fraction versus redshift data to constrain parameters of three different dark energy models: a cosmological constant dominated one ($Λ$CDM); the XCDM parameterization of dark energy; and a slowly-rolling scalar field model with inverse-power-law potential energy density. (Instead of using the Monte Carlo Markov Chain method, when integrating over nuisance parameters we use an alternative method of introducing an auxiliary random variable.) The resulting constraints are consistent with, and typically more constraining than, those derived from other cosmological data. A time-independent cosmological constant is a good fit to the galaxy cluster data, but slowly evolving dark energy cannot yet be ruled out.
