description: A general prescription for the treatment of constrained quantum motion is outlined. We consider in particular constraints defined by algebraic submanifolds of the quantum state space. The resulting formalism is applied to obtain solutions to the constrained dynamics of systems of multiple spin-1/2 particles. When the motion is constrained to a certain product space containing all of the energy eigenstates, the dynamics thus obtained are quasi-unitary in the sense that the equations of motion take a form identical to that of unitary motion, but with different boundary conditions. When the constrained subspace is a product space of disentangled states, the associated motion is more intricate. Nevertheless, the equations of motion satisfied by the dynamical variables are obtained in closed form.

description: Hyperspectral image (HSI) contains both spatial pattern and spectral information which has been widely used in food safety, remote sensing, and medical detection. However, the acquisition of hyperspectral images is usually costly due to the complicated apparatus for the acquisition of optical spectrum. Recently, it has been reported that HSI can be reconstructed from single RGB image using convolution neural network (CNN) algorithms. Compared with the traditional hyperspectral cameras, the method based on CNN algorithms is simple, portable and low cost. In this study, we focused on the influence of the RGB camera spectral sensitivity (CSS) on the HSI. A Xenon lamp incorporated with a monochromator were used as the standard light source to calibrate the CSS. And the experimental results show that the CSS plays a significant role in the reconstruction accuracy of an HSI. In addition, we proposed a new HSI reconstruction network where the dimensional structure of the original hyperspectral datacube was modified by 3D matrix transpose to improve the reconstruction accuracy.

description: The remarkable pre-main-sequence object V718 Per (HMW 15, H187) in the young cluster IC 348 periodically undergoes long-lasting eclipses caused by variable amounts of circumstellar dust in the line-of-sight to the star. It has been speculated that the star is a close binary and similar to another unusual eclipsing object, KH 15D. We have submitted V718 Per to a detailed photometric and spectroscopic study to find out more about the properties of the stellar object and the occulting circumstellar material, and to look for signatures of a possible binary component. Our photometric data show that the eclipses are very symmetric and persistent, and that the extinction deviates only little from what is expected for normal interstellar material. The spectroscopic data, obtained at minimum as well as at maximum brightness, indicate a primordial abundance of Li and a surface effective temperature of about 5200 K. Remarkably, the in-eclipse spectrum shows a significant broadening of the photospheric absorption lines, as well as a weak increase in emission components of H-alpha and the Ca II IR triplet. We did not detect any atomic or molecular features from to the occulting body in the in-eclipse spectrum. We also found no evidence of radial velocity changes in V718 Per to within about +/- 80 m/s, which for an edge-on system corresponds to a maximum companion mass of 6 Jupiter masses. Our observations suggest that V718 Per is a single star, and thus very different from KH 15D. We conclude that V718 Per is surrounded by an edge-on circumstellar disk with an irregular mass distribution orbiting at a distance of 3.3 AU from the star, presumably at the inner disk edge. We ascribe the broadening of photospheric absorption lines during the eclipse to forward scattering of stellar light in the circumstellar dust feature.

description: We have observed the persistent flow of Bose-condensed atoms in a toroidal trap. The flow persists without decay for up to 10 s, limited only by experimental factors such as drift and trap lifetime. The quantized rotation was initiated by transferring one unit, $\hbar$, of the orbital angular momentum from Laguerre-Gaussian photons to each atom. Stable flow was only possible when the trap was multiply-connected, and was observed with a BEC fraction as small as 15%. We also created flow with two units of angular momentum, and observed its splitting into two singly-charged vortices when the trap geometry was changed from multiply- to simply-connected.

description: Auf dem Joule-Thomson-Effekt basierende kryogene Gemischkältekreisläufe (cryogenic mixed-refrigerant cycles, CMRC) stellen eine kostengünstige, effiziente und beliebig skalierbare Technologie für die Kühlung bei Temperaturen unter 100 K dar. Damit eigenen sich Prozesse wie der mit weitsiedenden Kältemittelgemischen betriebene Linde-Hampson-Prozess beispielsweise für die Kühlung hochtemperatur-supraleitender Stromkabel. Im Betrieb führen die unterschiedlichen Löslichkeiten der Gemischkomponenten im Verdichteröl sowie Flüssigkeitsansammlungen in kalten Totvolumina zu einer Veränderung der zirkulierenden Gemischzusammensetzung, was in der Prozessentwicklung beachtet werden muss. Zur Optimierung der Prozesseffizienz und der Charakterisierung dieser Zusammensetzungsverschiebung beim Einsatz eines neuartigen kompakten mikrostrukturierten Wärmeübertragers wurden Untersuchungen an Stickstoff-Kohlenwasserstoff-Gemischen durchgeführt. Die Zusammensetzungen der eingesetzten Gemische wurden dabei gravimetrisch bei der Befüllung und im Betrieb off-line mit einem kalibrierten Gaschromatographen bestimmt. Die auf diese Weise erhobenen Daten zeigen eine geringere relative Verschiebung der Zusammensetzung als allgemein in der Literatur beschrieben, was auf das geringere innere Volumen des eingesetzten Wärmeübertragers zurückgeführt werden kann.
The life and extraordinary adventures of Private Ivan Chonkin by Vladimir Voinovich : a commentary and explication
Creators: name: Thomson, Sandra Mary
Publisher: name: University of British Columbia
Year: 2010

description: Vladimir Voinovich is the freshest satirical voice in Russian literature in the past fifty years. He has been called the new Gogol and his honest re-examination of his country's past has forced him into exile to West Germany. His novel, The Life and Extraordinary Adventures of Private Ivan Chonkin, is a satire of the idiocy of Stalinist times. It shows a slice of society from its lowliest representative, Ivan Chonkin, to its highest, Joseph Stalin. The authorial intent is to show the natural man in unnatural circumstances. Chonkin is the norm in this satire. He is the honest, natural, real man that Voinovich has described in various interviews as his favourite literary type. Standing opposed to the conventional hero of socialist realism fiction, Chonkin is the end of a line of Voinovich's own kind of positive hero that began in his early stories. Chonkin is official idiocy's final undoing. The purpose of satire is to criticize targets that are not fictions, but representations of reality that are, or should be, obvious to the reader. In Chonkin Voinovich critically portrays various realia of the Stalin era, puncturing various myths and fictions. The novel's various characters represent mutilating aspects of the Stalinist regime in the 1930s and 1940s. The author successfully uses low burlesque to ridicule these satiric targets. Each of the chapters in the thesis identifies satirical targets and explicates them in the light of the appropriate historical, political, intellectual, or economic events. These realia may be immediately recognizable to the older, more astute Russian readers who have survived Stalin. They are not recognizable nor is their impact fully understood by the common reader either in the Soviet Union or in the West. Consequently, this fact alone justifies my attempt at a commentary and explication of Voinovich's masterful satirical portrayal of Stalinist Russia.

description: O empreendedorismo neoliberal se baseia na lógica da desregulamentação do trabalho e intervenção mínima do Estado em questões econômicas. É frequentemente camuflado por valores positivos atribuídos a indivíduos supostamente capazes de alcançar sucesso por esforços próprios, fortalecendo o discurso da meritocracia, acirrando a disputa entre trabalhadores, compelindo a redução salarial, a apatia política e o enfraquecimento sindical. Neste estudo, analisamos como o discurso neoliberal do empreendedorismo se manifesta em narrativas de vida de três autores autopublicados em plataformas digitais cujos contratos baseiam-se na lógica do Capitalismo de Plataforma. Foram analisadas entrevistas com autores, com uma perspectiva discursiva da linguagem, levando em consideração, principalmente, o conceito de ethos discursivo e técnicas de narrativa de si. Os resultados demonstram que a adesão à ideia do empreendedorismo se manifesta nas três narrativas analisadas e que pode levar o autor a se render a uma espécie de curadoria algorítmica, produzindo livros conforme tendências de mercado para atingir a viralização na plataforma e obter um lucro significativo por meio e um pagamento irrisório.
Depressive attributional style and depression following childbirth
Creators: name: Manly, Patricia Colleen
Publisher: name: University of British Columbia
Year: 2010

description: The reformulated learned helplessness model posits that individuals who make internal, stable and global attributions for undesired outcomes are more likely than others to become depressed when faced with important life events that are perceived as uncontrollable. Seligman, Abramson, Semmel and von Baeyer (1979) found significant correlations between attributional style and concurrent measures of depression in a sample of college undergraduates. The purpose of the present study was to address two questions arising from the Seligman et al. study within the context of the event of childbirth. The first question was whether the relationship between depressive attributional style and concurrent depression found in college undergraduates could be extended to women anticipating the birth of their first child. The second question was whether depressive attributional style would have predictive utility with this group, that is, whether women's prenatal attributional style would be predictive of depression in the first week postpartum. The results provide neglible support for the notion of depressive attributional style as defined by the reformulated learned helplessness hypothesis. Although this study was not designed to test hypotheses based upon any other model of depression, the findings were consistent with Beck's (1967) formulation. Several alternative explanations for the discrepancy between the present findings and those reported by Seligman et al. are discussed. Notably, 17% of this relatively homogeneous sample of primiparous women reported depression of clinical severity during the first week postpartum.

description: We use a nanowire quantum dot to probe high-frequency current fluctuations in a nearby quantum point contact. The fluctuations drive charge transitions in the quantum dot, which are measured in real-time with single-electron detection techniques. The quantum point contact (GaAs) and the quantum dot (InAs) are fabricated in different material systems, which indicates that the interactions are mediated by photons rather than phonons. The large energy scales of the nanowire quantum dot allow radiation detection in the long-wavelength infrared regime.

description: Legal judgment prediction(LJP) is an essential task for legal AI. While prior methods studied on this topic in a pseudo setting by employing the judge-summarized case narrative as the input to predict the judgment, neglecting critical case life-cycle information in real court setting could threaten the case logic representation quality and prediction correctness. In this paper, we introduce a novel challenging dataset from real courtrooms to predict the legal judgment in a reasonably encyclopedic manner by leveraging the genuine input of the case -- plaintiff's claims and court debate data, from which the case's facts are automatically recognized by comprehensively understanding the multi-role dialogues of the court debate, and then learnt to discriminate the claims so as to reach the final judgment through multi-task learning. An extensive set of experiments with a large civil trial data set shows that the proposed model can more accurately characterize the interactions among claims, fact and debate for legal judgment prediction, achieving significant improvements over strong state-of-the-art baselines. Moreover, the user study conducted with real judges and law school students shows the neural predictions can also be interpretable and easily observed, and thus enhancing the trial efficiency and judgment quality.

description: We present a novel deep neural model for text detection in document images. For robust text detection in noisy scanned documents, the advantages of multi-task learning are adopted by adding an auxiliary task of text enhancement. Namely, our proposed model is designed to perform noise reduction and text region enhancement as well as text detection. Moreover, we enrich the training data for the model with synthesized document images that are fully labeled for text detection and enhancement, thus overcome the insufficiency of labeled document image data. For the effective exploitation of the synthetic and real data, the training process is separated in two phases. The first phase is training only synthetic data in a fully-supervised manner. Then real data with only detection labels are added in the second phase. The enhancement task for the real data is weakly-supervised with information from their detection labels. Our methods are demonstrated in a real document dataset with performances exceeding those of other text detection methods. Moreover, ablations are conducted and the results confirm the effectiveness of the synthetic data, auxiliary task, and weak-supervision. Whereas the existing text detection studies mostly focus on the text in scenes, our proposed method is optimized to the applications for the text in scanned documents.

description: The interaction between electrons in graphene under high magnetic fields drives the formation of a rich set of quantum Hall ferromagnetic phases (QHFM), with broken spin or valley symmetry. Visualizing atomic scale electronic wavefunctions with scanning tunneling spectroscopy (STS), we resolve microscopic signatures of valley ordering in QHFM and fractional quantum Hall phases of graphene. At charge neutrality, we observe a field-tuned continuous quantum phase transition from a valley polarized state to an intervalley coherent state, with a Kekule distortion of its electronic density. Mapping the valley texture extracted from STS measurements of the Kekule phase, we visualize valley skyrmion excitations localized near charged defects. Our techniques can be applied to examine valley ordered phases and their topological excitations in a wide range of materials.

description: The Chinese Super League (CSL) has witnessed a dramatic development through the last decade, and CSL football clubs have embraced new business models. This thesis reviewed the CSL with the aim of understanding the new business models in the emerging CSL ecosystem and providing insight into the long-term sustainability of the CSL. The study set out to answer three research questions: RQ 1: What are the business models of CSL clubs?; RQ 2: How do CSL clubs undertake their business model innovations (BMI)?; RQ 3: How does the CSL ecosystem influence the BMI of the clubs?The research adopts the management concepts of business models (Amit & Zott, 2001; Osterwalder & Pigneur, 2010); business model innovation (Foss & Saebi, 2017; Massa & Tucci) and business ecosystems (Moore, 1996). It investigates how these concepts can guide to explain the business phenomenon in CSL and how these concepts are interacted and connected. The study employs a multi-case study approach and includes 10 CSL clubs. Data was collected via semi-structured interviews with senior managers from investigated clubs, whilst questionnaires and substantial secondary data were also collected for analysis.The findings indicate the level of investors’ support differentiate the core capabilities and value creation of CSL football clubs’ business models. Whilst CSL clubs focus on capturing brand value for investors, they have loss-making financial structures that need to be amended urgently. For BMI, Evergrande FC utilised their visionary thinking to design and constantly improve their disruptive business model. Other clubs are either encouraged or forced by Evergrande to adapt their business models based on their strategic positionings. Though Evergrande’s innovative model has led to their dominant success in CSL, it is criticised for jeopardising the collective long-term sustainability of the CSL. The CSL ecosystem was examined via the impact of seven ecosystem factors: clubs, fans, football culture, investors, media, policy, and technology. The data identified that policy and investors are the most significant factors in the CSL ecosystem that have an overwhelming influence on CSL clubs’ BMI decisions. A structural change to club management, the development of the football culture, and the growth of the fanbase of clubs in the CSL ecosystem are expected.Future research should monitor the upcoming transition of the CSL ecosystem and CSL clubs. It can evaluate the changes in CSL clubs’ value creation and value capture and examine whether sustainability has been implemented within the CSL. This research develops research frameworks that can be applied to analyse the new business models of CSL clubs and the efficiency of future ecosystem structure. Other key CSL ecosystem stakeholders, such as governments and fans, can be the focal points in future research to gain a more comprehensive understanding of the CSL.

description: The study was carried out at the Teaching and Research Farm of Federal University Wukari, Taraba State, Nigeria to evaluate the effect of vine pattern of planting on the growth and tuber yield of two sweet potato variety. The treatments consisted of two varieties of sweet potato namely white skin and Pink skin variety and four vine planting patterns indicated as direct vine planting, one ring, two rings and three rings vine planting. These were arranged in a Randomized Complete Block Design (RCBD) replicated three times. Data were collected on the growth and tuber yield parameters and analyzed using ANOVA and the differences among the treatment means was separated using Duncan Multiple Range Test as 5% level of probability. The results obtained showed that the vine planting pattern significantly affected the growth and tuber yield of the crop. The pink skin variety gave significantly highest primary vine length of (240.31cm), number of leaves (266.53) and number of nodes (446.56) while the white flesh variety had significantly higher number of secondary vines of (53.33cm). The two rings vine pattern planting produced significantly highest length of primary vine (331.56cm), number of secondary vine (47.39cm), number of leaves (728.17), number of nodes (694.44), best canopy coverage and leaf area of (131.32cm) The white skin variety produced significantly higher tuber weights of 2.76kg, width of tubers (38.15cm), and the length of tubers (22.0cm), while pink skin variety produced highest significant tuber number (8.5). The two rings and three rings vine patterns of planting exhibited similar influence on the yield of sweet potato (8.28kg and 8.11kg) respectively. Therefore, planting sweet potato using two rings vine planting pattern is best for the optimal production of sweet potato.

Mathematically, this problem can be formulated as one in combinatorics or graph theory. It consists in finding a recursive algorithm that generates all connected graphs in their Hopf algebraic representation. This representation can be used directly and efficiently in evaluating Feynman graphs as contributions to the n-point functions.

description: We investigate the possibility of encoding multiple solutions of a problem in a single chromosome. The best solution encoded in an individual will represent (will provide the fitness of) that individual. In order to obtain some benefits the chromosome decoding process must have the same complexity as in the case of a single solution in a chromosome. Three Genetic Programming techniques are analyzed for this purpose: Multi Expression Programming, Linear Genetic Programming, and Infix Form Genetic Programming. Numerical experiments show that encoding multiple solutions in a chromosome greatly improves the search process.

description: The quasi-two-dimensional electronic gas at the (111) SrTiO$_3$-based heterostructure interfaces is described by a multi-band tight-binding model providing electronic bands in agreement at low energies with photoemission experiments. We analyze both the roles of the spin-orbit coupling and of the trigonal crystal field effects. We point out the presence of a regime with sizable strain where the band structure exhibits a Dirac cone whose features are consistent with \textit{ab-initio} approaches. The combined effect of spin-orbit coupling and trigonal strain gives rise to non-trivial spin and orbital angular momenta patterns in the Brillouin zone and to quantum spin Hall effect by opening a gap at the Dirac cone. The system can switch from a conducting to a topological insulating state \textit{via} modification of trigonal strain within a parameter range which is estimated to be experimentally achievable.

description: The equilibrium rotation of tidally evolved "Earth-like" extra-solar planets is often assumed to be synchronous with their orbital mean motion. The same assumption persisted for Mercury and Venus until radar observations revealed their true spin rates. As many of these planets follow eccentric orbits and are believed to host dense atmospheres, we expect the equilibrium rotation to differ from the synchronous motion. Here we provide a general description of the allowed final equilibrium rotation states of these planets, and apply this to already discovered cases in which the mass is lower than twelve Earth-masses. At low obliquity and moderate eccentricity, it is shown that there are at most four distinct equilibrium possibilities, one of which can be retrograde. Because most presently known "Earth-like" planets present eccentric orbits, their equilibrium rotation is unlikely to be synchronous.

description: Excerpts from the report Introduction: As the major market in the upper Midwest, the Minneapolis-St. Paul market supplies fruits and vegetables throughout Minnesota and into parts of South Dakota, North Dakota, Michigan, Wisconsin, and Canada. One firm makes regular truck shipments to Winnipeg, Manitoba, a distance of 450 miles, and several firms provide regular service to customers 200 to 300 miles from the Twin Cities (Minneapolis-St. Paul). In contrast, the Duluth-Superior market is primarily local, receiving almost half of its volume from Minneapolis- St, Paul, and most sales are made within a radius of 50 miles of the market. This report describes the organization and operation of these markets, including the buying, selling, and operating practices of wholesalers and chains in both markets, and the changes that have occurred in Minneapolis- St. Paul during the past 30 years. Information on which this report is based was obtained as part of a nationwide study of the organization and operations of wholesale produce markets. The purpose of the study was to describe and appraise the status of wholesale markets and to determine changes that have occurred.
Career aspirations of upper year university students

description: One hundred and six female and 53 male upper year university students participated in a questionnaire study of career aspirations. The questionnaire covered the topics of perceived parental closeness, support, and sex role endorsement; maternal employment,'career commitment, influences on career choice, career values, and desired adult role commitments. Measures of eight personality traits were included: Abasement, Achievement, Affiliation, Autonomy, Dominance, Endurance, Nurturance, and Succorance. The women respondents were divided into two groups based on whether their career choices were traditionally or nontraditionally feminine. Three groups were formed: traditional women (N =48), nontraditional women (N=58), and men. As hypothesized, the two groups of women differed. More of the nontraditional women had mothers who were employed during the respondent's childhood. The traditional women reported being influenced, in making their career choice, by a greater number of factors. In terms of career related features the traditional women more often valued being able to help others while the nontraditional women were more concerned with salary potential, freedom from supervision, and job availability. Discriminant function analysis revealed that the two groups of women could be differentiated by the eight personality trait measures. Univariate analysis revealed that, the traditional women scored higher on Affiliation and Nurturance. The nontraditional women desired fewer children than the traditional women. They reported being somewhat more liberal in their conceptions of their future marital roles. The men studied indicated more traditional conceptions of their future roles than both groups of women. Few men indicated willingness to limit their job participation to attend to child care. The realism of women's career aspirations was discussed in terms of both academic preparation and marital role demands. Changing trends in adult roles for both sexes were considered. Methodological problems inherent in the study of women's career aspirations and career participation were discussed along with recommendations for further research.

description: Stark shifts of potassium and rubidium D1 lines have been measured with high precision by Miller et al [1]. In this work, we combine these measurements with our all-order calculations to determine the values of the electric-dipole matrix elements for the 4p_j-3d_j' transitions in K and for the 5p_j-4d_j' transitions in Rb to high precision. The 4p_1/2-3d_3/2 and 5p_1/2-4d_3/2 transitions contribute on the order of 90% to the respective polarizabilities of the np_1/2 states in K and Rb, and the remaining 10% can be accurately calculated using the relativistic all-order method. Therefore, the combination of the experimental data and theoretical calculations allows us to determine the np-(n-1)d matrix elements and their uncertainties. We compare these values with our all-order calculations of the np-(n-1)d matrix elements in K and Rb for a benchmark test of the accuracy of the all-order method for transitions involving nd states. Such matrix elements are of special interest for many applications, such as determination of magic wavelengths in alkali-metal atoms for state-insensitive cooling and trapping and determination of blackbody radiation shifts in optical frequency standards with ions.

description: The pioneering work of establishing a climate smart village (CSV) in Guinayangan, Quezon Province in 2014 became an avenue for promoting interventions to address climate change in a local government in the Philippines. The CSV served as a laboratory where climate-smart technologies and practices were tested, promoted, and scaled out. Through a CSV, Climate-Smart Agriculture was introduced as an integrated approach that aims to achieve short- and long-term agriculture development priorities in the face of climate change. With the project coming to an end, the immediate, intermediate, and ultimate outcomes were identified among different sectors through the process of outcome harvesting. Evidence of change were collected and analyzed to identify the outcomes through engagement with farmers, key persons, and other local leaders. Identified outcomes included changes in awareness, knowledge, practices, approaches, and strategies, particularly with individual farmers, community organizations, municipality, and even at the national level. Significantly, the CSV became a learning platform to farmers – experiences and knowledge were gained and spread not only within their learning groups, but also to other farmers, community organizations, and local executives in the municipality. The achievements and contributions of CSV in Guinayangan has reached a higher scale – it influenced the national implementation of the Adaptation and Mitigation Initiative for Agriculture (AMIA) Program, a flagship program by the Department of Agriculture (DA). AMIA villages were established across all regions of the Philippines, many of which were inspired by the opportunities to visit the CSV in Guinayangan on at least two occasions. The CSVs established by the International Institute of Rural Reconstruction (IIRR) served as an advanced CSV in the initial years of the DA AMIA National Program. IIRR supported the DA and FAO efforts to develop policy briefs based on experiences from the DA AMIA Program.

description: The correspondence limit of the atomic elliptic state in three dimensions is discussed in terms of Nelson's stochastic mechanics. In previous work we have shown that this approach leads to a limiting Nelson diffusion and here we discuss in detail the invariant measure for this process and show that it is concentrated on the Kepler ellipse in the plane z=0. We then show that the limiting Nelson diffusion generator has a spectral gap; thereby proving that in the infinite time limit the density for the limiting Nelson diffusion will converge to its invariant measure. We also include a summary of the Cheeger and Poincare inequalities both of which are used in our proof of the existence of the spectral gap.

Mass-loss and diffusion in subdwarf B stars and hot white dwarfs: do weak winds exist?
Creators: name: Unglaub, Klaus

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

description: The effect of diffusion on the chemical composition of subdwarf B (sdB) stars and of hot white dwarfs strongly depends on the presence of weak winds. In the paper, for stars with half a solar mass, for various effective temperatures between 25000 K and 50000 K, and for various metallicities between solar and 1/100 solar, the mass loss rates are predicted as a function of the surface gravity. With assumptions similar to the original theory of radiatively driven winds, the method of solution of the momentum equation has been modified, because the usual parametrization of the line force multiplier leads to complications in the case of weak winds. According to the results, weak winds with mass-loss rates of the order E-11 solar masses per year may exist only for the most luminous sdB stars. For the more compact ones, the decoupling of the metals from the bulk matter (hydrogen and helium) is expected in the wind region, because the momentum exchange via Coulomb collisions is not effective enough. Thus multicomponent effects are of great importance. For the case of white dwarfs no wind solution exists at all, if multicomponent effects are neglected.

description: The distribution of stellar metallicities within and across galaxies is an excellent relic of the chemical evolution across cosmic time. We present a detailed analysis of spatially resolved stellar populations based on $>2.6$ million spatial bins from 7439 nearby galaxies in the SDSS-IV MaNGA survey. To account for accurate inclination corrections, we derive an equation for morphology dependent determination of galaxy inclinations. Our study goes beyond the well-known global mass-metallicity relation and radial metallicity gradients by providing a statistically sound exploration of local relations between stellar metallicity $[Z/H]$, stellar surface mass density $Σ_\star$ and galactocentric distance in the global mass-morphology plane. We find a significant resolved mass density-metallicity relation $\rm rΣ_\star ZR$ for galaxies of all types and masses above $10^{9.8}\,\mathrm{M_\odot}$. Different radial distances make an important contribution to the spread of the relation. Particularly, in low and intermediate mass galaxies, we find that at fixed $Σ_\star$ metallicity increases with radius independently of morphology. For high masses, this radial dependence is only observed in high $Σ_\star$ regions of spiral galaxies. This result calls for a driver of metallicity, in addition to $Σ_\star$ that promotes chemical enrichment in the outer parts of galaxies more strongly than in the inner parts. We discuss gas accretion, outflows, recycling and radial migration as possible scenarios.

description: We study a noncommutative deformation of general relativity where the gravitational field is described by a matrix-valued symmetric two-tensor field. The equations of motion are derived in the framework of this new theory by varying a diffeomorphisms and gauge invariant action constructed by using a matrix-valued scalar curvature. Interestingly the genuine noncommutative part of the dynamical equations is described only in terms of a particular tensor density that vanishes identically in the commutative limit. A noncommutative generalization of the energy-momentum tensor for the matter field is studied as well.

Kurmanbek Bakiev

description: This paper analyzes the process and dynamics of the protests in the Kyrgyz Republic that led to the April 7, 2010 overthrow of the government of President Kurmanbek Bakiev. The paper argues that the government overthrow was not a sudden event; rather it was a continuation of a long succession of protests and violence that had been occurring for years. The Kyrgyz Republic has an endemic problem of solving all political and social problems through street protests and violence. The long-term trend is worrisome, as street protests are likely to continue into the future unless the government and the opposition find a way to address legitimate grievances through democratic institutions. This paper examines the history of Kyrgyz protests by comparing the protests in 2002, the government overthrow in 2005, and the events immediately prior to the 2010 collapse of the government. It suggests that the framework for the protests was similar in all three cases and that government attacks on local political entrepreneurs motivated the public to respond. The ineffective use of government force that followed incensed, but did not overwhelm, the protesters.

description: We apply the Distillation spatial smearing program to the extraction of the unpolarized isovector valence PDF of the nucleon. The improved volume sampling and control of excited-states afforded by distillation leads to a dramatically improved determination of the requisite Ioffe-time Pseudo-distribution (pITD). The impact of higher-twist effects is subsequently explored by extending the Wilson line length present in our non-local operators to one half the spatial extent of the lattice ensemble considered. The valence PDF is extracted by analyzing both the matched Ioffe-time Distribution (ITD), as well as a direct matching of the pITD to the PDF. Through development of a novel prescription to obtain the PDF from the pITD, we establish a concerning deviation of the pITD from the expected DGLAP evolution of the pseudo-PDF. The presence of DGLAP evolution is observed once more following introduction of a discretization term into the PDF extractions. Observance and correction of this discrepancy further highlights the utility of distillation in such structure studies.

description: We study the properties of black holes of mass 10^4--10^{11} GeV in models with the fundamental scale of gravity at the TeV. These black holes could be produced in the collision of a ultrahigh energy cosmic ray with a dark matter particle in our galactic halo or with another cosmic ray. We show that QCD bremsstrahlung and pair production processes are unable to thermalize the particles exiting the black hole, so a chromosphere is never formed during Hawking evaporation. We evaluate with HERWIG the spectrum of stable 4-dim particles emitted during the Schwarzschild phase and find that in all cases it is peaked at energies around 0.2 GeV, with an approximate 43% of neutrinos, 28% of photons, 16% of electrons and 13% of protons. Bulk gravitons are peaked at higher energies, they account for a 0.4% of the particles (16% of the total energy) emitted by the most massive black holes in n=6 extra dimensions or just the 0.02% of the particles (1.4% of the energy) emitted by a 10 TeV black hole for n=2.

description: We performed systematic angle-resolved photoemission spectroscopy measurements $in$-$situ$ on $T'$-${\rm La}_{2-x}{\rm Ce}_x\rm {CuO}_{4\pmδ}$ (LCCO) thin films over the extended doping range prepared by the refined ozone/vacuum annealing method. Electron doping level ($n$), estimated from the measured Fermi surface volume, varies from 0.05 to 0.23, which covers the whole superconducting dome. We observed an absence of the insulating behavior around $n \sim$ 0.05 and the Fermi surface reconstruction shifted to $n \sim$ 0.11 in LCCO compared to that of other electron-doped cuprates at around 0.15, suggesting that antiferromagnetism is strongly suppressed in this material. The possible explanation may lie in the enhanced -$t'$ /$t$ in LCCO for the largest $\rm{La^{3+}}$ ionic radius among all the Lanthanide elements.
