description: The negligible eccentricity of all extra solar planets with periods less than six days can be accounted for by dissipation of tidal disturbances within their envelopes which are induced by their host stars. In the period range of 7-21 days, planets with circular orbits coexist with planets with eccentric orbits. These will be referred to as the borderline planets. We propose that this discrepancy can be attributed to the variation in spin-down rates of young stars. In particular, prior to spin-down, dissipation of a planet's tidal disturbance within the envelope of a sufficiently rapidly spinning star can excite eccentricity growth, and for a more slowly spinning star, at least reduce the eccentricity damping rate. In contrast, tidal dissipation within the envelope of a slowly spinning low-mass mature star can enhance the eccentricity damping process. Based on these results, we suggest that short-period planets around relatively young stars may have a much larger dispersion in eccentricity than those around mature stars. We also suggest that because the rate of angular momentum loss from G and K dwarfs via stellar winds is much faster than the tidal transfer of angular momentum between themselves and their very-short (3-4 days) period planets, they cannot establish a dynamical configuration in which the stellar and planetary spins are approximately parallel and synchronous with the orbital frequency. In principle, however, such configurations may be established for planets (around G and K dwarfs) with orbital periods of up to several weeks. In contrast to G and K dwarfs, the angular momentum loss due to stellar winds is much weaker in F dwarfs. It is therefore possible for synchronized short-period planets to exist around such stars. The planet around Tau Boo is one such example.

description: In this paper, we develop a gradient-free optimization methodology for efficient resource allocation in Gaussian MIMO multiple access channels. Our approach combines two main ingredients: (i) an entropic semidefinite optimization based on matrix exponential learning (MXL); and (ii) a one-shot gradient estimator which achieves low variance through the reuse of past information. This novel algorithm, which we call gradient-free MXL algorithm with callbacks (MXL0$^{+}$), retains the convergence speed of gradient-based methods while requiring minimal feedback per iteration$-$a single scalar. In more detail, in a MIMO multiple access channel with $K$ users and $M$ transmit antennas per user, the MXL0$^{+}$ algorithm achieves $ε$-optimality within $\text{poly}(K,M)/ε^2$ iterations (on average and with high probability), even when implemented in a fully distributed, asynchronous manner. For cross-validation, we also perform a series of numerical experiments in medium- to large-scale MIMO networks under realistic channel conditions. Throughout our experiments, the performance of MXL0$^{+}$ matches$-$and sometimes exceeds$-$that of gradient-based MXL methods, all the while operating with a vastly reduced communication overhead. In view of these findings, the MXL0$^{+}$ algorithm appears to be uniquely suited for distributed massive MIMO systems where gradient calculations can become prohibitively expensive.

Aesthetics - Wittgenstein’s Paradigm of Philosophy?

description: This paper attempts to elucidate Wittgenstein’s remark about the “strange resemblance between a philosophical investigation (especially in mathematics) and an aesthetic one” from 1937 by looking at its textual and philosophical context. The conclusion is that the remark can be seen both as a description of a particular conception of philosophy, a prescription or declaration of intent (to proceed in a particular way), and a reminder (to Wittgenstein himself) about the form of a philosophical investigation. Furthermore, it is concluded that the Darstellungsform he has in mind is the one that finds expression especially in the first part of the PI.

Molecular hydrogen beyond the optical edge of an isolated spiral galaxy

Year: 2004

description: We know little about the outermost portions of galaxies because there is little light coming from them. We do know that in many cases atomic hydrogen (HI) extends well beyond the optical radius \cite{Casertano91}. In the centers of galaxies, however, molecular hydrogen (H2) usually dominates by a large factor, raising the question of whether H2 is abundant also in the outer regions but hitherto unseen.Here we report the detection of emission from carbon monoxide (CO), the most abundant tracer of H2, beyond the optical radius of the nearby galaxy NGC 4414. The molecular clouds probably formed in the regions of relatively high HI column density and in the absence of spiral density waves. The relative strength of the lines from the two lowest rotational levels indicates that both the temperature and density of the H2 are quite low compared to conditions closer to the center. The inferred surface density of the molecular material continues the monotonic decrease from the inner regions. We conclude that while molecular clouds can form in the outer region of this galaxy, there is little mass associated with them.

description: We study the phenomenological impact of a recently suggested formalism for the combination of threshold and a so-called threshold-improved transverse momentum resummation, by using it to improve the fixed-order results. This formalism allows for a systematic improvement of the transverse momentum resummation that is valid in the entire range of $p_T$ by the inclusion of the threshold contribution. We use the Borel method as a suitable prescription for defining the inverse Mellin and Fourier transforms in the context of combined resummed expression. The study is applied to two QCD processes, namely the Higgs boson produced via gluon fusion and $Z$ boson production via the Drell--Yan mechanism. We compare our results to the standard transverse momentum resummation, as well as to the fixed-order results. We find that the threshold-improved transverse momentum resummation leads to faster perturbative convergence at small $p_T$ while the inclusion of threshold resummation improves the agreement with fixed-order calculations at medium and large $p_T$. These effects are more pronounced in the case of Higgs which is known to have slower perturbative convergence.

Topics in singular boundary value problems, evolution equations and mass transport
Creators: name: Kang, Xiaosong
Publisher: name: University of British Columbia
Year: 2009

description: In the first part of this thesis, the Hardy-Sobolev critical semilinear equations are studied via variational methods. Unlike the non-singular case s = 0, or the case when 0 belongs to the interior of a domain Ω in IRn, we show that the value and the attainability of the best Hardy-Sobolev constant on a smooth domain Ω, μs(Ω) := inf [Chemical Equation] when 0 < s < 2, 2*(s) = [Chemical Equation], and when 0 is on the boundary ∂Ω are closely related to the properties of the curvature of ∂Ω at 0. These conditions on the curvature are also relevant to the study of elliptic partial differential equations with singular potentials of the form: -Δu = [Chemical Equation] where f is a lower order perturbative term at infinity and f(x,0) = 0. We show that the positivity of the sectional curvature at 0 is relevant when dealing with Dirichlet boundary conditions, while the Neumann problems seem to require the positivity of the mean curvature at 0. This is joint work with Nassif Ghoussoub. In the second part of this thesis, we prove, using comparison principles, the strict localization in the Cauchy problem for unbounded solutions to a porous medium type equation with a source term, [Chemical Equation] , in the case of arbitrary compactly supported initial functions u0. An estimate on the support in terms of supp u0 and the blow-up time T is also derived. Our result extends the well-known one dimensional case and solves an open problem in this field. This is joint work with Changfeng Gui. In the last part of the work, using the Monge-Kantorovich theory of mass transport, we establish an inequality for the relative total energy - internal, potential and interactive - of two arbitrary probability densities, their Wasserstein distance, their barycenters and their entropy production functional. This inequality is remarkably encompassing as it implies most known geometrical - Gaussian and Euclidean - inequalities as well as new ones, while allowing a direct and unified way for computing best constants and extremals. As expected, such inequalities also lead to exponential rates of convergence to equilibria for solutions of Fokker- Planck and McKean-Vlasov type equations. The proposed inequality also leads to a remarkable correspondence between ground state solutions of certain quasilinear (or semi-linear) equations and stationary solutions of (non-linear) Fokker-Planck type equations. This is joint work with Martial Agueh and Nassif Ghoussoub.

We obtained an estimetion of the intensity of the 10 mT doublet characterizing the EPR spectrum of such a defect arising from hyperfine interaction of the unpaired electron with a 29Si (I=1/2) nucleus. Moreover, determining the intensity ratio between this hyperfine doublet and the main resonance line of E'-delta center, we pointed out that unpaired electron wave function of this center is actually delocalized over four nearly equivalent silicon atoms.

description: A cell's behavior is a consequence of the complex interactions between its numerous constituents, such as DNA, RNA, proteins and small molecules. Cells use signaling pathways and regulatory mechanisms to coordinate multiple processes, allowing them to respond to and adapt to an ever-changing environment. The large number of components, the degree of interconnectivity and the complex control of cellular networks are becoming evident in the integrated genomic and proteomic analyses that are emerging. It is increasingly recognized that the understanding of properties that arise from whole-cell function require integrated, theoretical descriptions of the relationships between different cellular components. Recent theoretical advances allow us to describe cellular network structure with graph concepts, and have revealed organizational features shared with numerous non-biological networks. How do we quantitatively describe a network of hundreds or thousands of interacting components? Does the observed topology of cellular networks give us clues about their evolution? How does cellular networks' organization influence their function and dynamical responses? This article will review the recent advances in addressing these questions.

After introducing the basic concepts of LE spectral synthesis, by means of LE models and real observations we investigate the deviations from pure SN spectra, light and colour curves, the signatures that witness the presence of a LE and the possible inferences on the extinction law. The effects on the photometric parameters and spectral features are also discussed. In particular, for the case of circumstellar dust, LEs are found to introduce an apparent relation between the post-maximum decline rate and the absolute luminosity which is most likely going to affect the well known Pskowski-Phillips relation.

description: There is an emerging consensus among macro-economists that differences in technology across countries accounts for the major differences in per-capita GDP and the wages of workers with similar skills across countries. Accounting for differences in technology levels across countries thus can go a long way towards understanding global inequality. One mechanism by which poorer countries can catch up with richer countries is through technological diffusion, the adoption by low-income countries of the advanced technologies produced in high-income countries. In this survey, we examine recent micro studies that focus on understanding the adoption process. If technological diffusion is a major channel by which poor countries can develop, it must be the case that technology adoption is incomplete or the inputs associated with the technologies are under-utilized in poor, or slow-growing economies. Thus, obtaining a better understanding of the constraints on adoption are useful in understanding a major component of growth.

description: CERN-LHC. A measurement of the cross section for the production of isolated prompt photons in pp collisions at a center-of-mass energy sqrt(s) = 7 TeV is presented. The results are based on an integrated luminosity of 4.6 fb-1 collected with the ATLAS detector at the LHC. The cross section is measured as a function of photon pseudorapidity and transverse energy in the kinematic range between 100 GeV and 1000 GeV and in the regions of pseudorapidity less than 1.37 and between 1.52 and 2.37. The results are compared to leading-order parton-shower Monte Carlo models and next-to-leading-order perturbative QCD calculations. Next-to-leading-order perturbative QCD calculations agree well with the measured cross sections as a function of transverse energy and pseudorapidity UPDATE (27 FEB 2015): The detailed information on bin-to-bin correlated and uncorrelated uncertainties has been made available as additional text file under the link below.

description: The population of exoplanetary systems detected by Kepler provides opportunities to refine our understanding of planet formation. Unraveling the conditions needed to produce the observed exoplanets will sallow us to make informed predictions as to where habitable worlds exist within the galaxy. In this paper, we examine using N-body simulations how the properties of planetary systems are determined during the final stages of assembly. While accretion is a chaotic process, trends in the ensemble properties of planetary systems provide a memory of the initial distribution of solid mass around a star prior to accretion. We also use EPOS, the Exoplanet Population Observation Simulator, to account for detection biases and show that different accretion scenarios can be distinguished from observations of the Kepler systems. We show that the period of the innermost planet, the ratio of orbital periods of adjacent planets, and masses of the planets are determined by the total mass and radial distribution of embryos and planetesimals at the beginning of accretion. In general, some amount of orbital damping, either via planetesimals or gas, during accretion is needed to match the whole population of exoplanets. Surprisingly, all simulated planetary systems have planets that are similar in size, showing that the "peas in a pod" pattern can be consistent with both a giant impact scenario and a planet migration scenario. The inclusion of material at distances larger than what Kepler observes has a profound impact on the observed planetary architectures, and thus on the formation and delivery of volatiles to possible habitable worlds.

description: We consider the reaction g+d -> pi+d in a wide energy range around and above the eta-meson photoproduction threshold at backward CM angles of the outgoing pion. Our theoretical analysis is essentially motivated by the recent measurements of the CLAS Collaboration at Jefferson Lab, where this kinematical region of the reaction has been thoroughly studied for the first time and a cusps in the energy dependence of the differential cross section in the region of Eg = 600-800 MeV has been observed. Our preliminary and qualitative analysis, based on single- and double-scattering diagrams, shows that the observed structure can be explained by the contribution of the double-scattering diagram with intermediate production of the eta meson. The effect, to a considerable extent, is formed due to the contribution of N(1535) resonance to the amplitudes of subprocesses on the nucleons.

Grammar and Aesthetic Mechanismus. From Wittgenstein’s Tractatus to the Lectures on Aesthetics

Year: 2013

description: This paper takes distances from two influential images of Wittgenstein's philosophy: the image of a primarily ethical philosopher defended by the so-called «resolute» interpreters and that of an ascetically "analytical" philosopher transmitted by the standard interpretation. Instead of contrasting images (that of Wittgenstein as an "aesthetic" philosopher and that of the "ethical" Wittgenstein), this paper focuses on the analysis of the fractures and tensions characterizing not only the relationship between Wittgenstein's philosophy and aesthetics, but also the very style of Wittgenstein's thought. Addressing a specific issue from a conceptual and textual standpoint (the unity of Ethics and Aesthetics in the Tractatus) seems to the author to be a fruitful strategy that allows us not only to understand whether and how determinant and central the aesthetic problem is for Wittgenstein, but also to see how aesthetics itself can be radically reshaped through the filter offered by his thought. In the first place, then, it is clarified what the Tractatus claim that ethics and aesthetics «sind eins» might entail. Secondly, it is checked if and how the conceptual consistency of the «being one» of ethics and aesthetics is transformed during the 1930s, to the point that it requires a different configuration: the metamor¬phosis of the logical unity between the two conceptual fields into an analogical affinity. Analyzing this conceptual metamorphosis the paper considers also the idea of an asymmetry of the aesthetic over the ethical as already evident, despite appearances, in the 1929 Lecture on Ethics. This asymmetry is then developed focusing the image of grammatical mechanism with its degrees of freedom of which Wittgensteins writes from 1930. In connection with this image the author outlines finally the idea of an aesthetic mechanism arising from primitive reactions and strictly related with the genesis of language games.

description: Weighted constellations give graphical representations of weighted branched coverings of the Riemann sphere. They were introduced to provide a combinatorial interpretation of the $2$D Toda $τ$-functions of hypergeometric type serving as generating functions for weighted Hurwitz numbers in the case of polynomial weight generating functions. The product over all vertex and edge weights of a given weighted constellation, summed over all configurations, reproduces the $τ$-function. In the present work, this is generalized to constellations in which the weighting parameters are determined by a rational weight generating function. The associated $τ$-function may be expressed as a sum over the weights of doubly labelled weighted constellations, with two types of weighting parameters associated to each equivalence class of branched coverings. The double labelling of branch points, referred to as "colour" and "flavour" indices, is required by the fact that, in the Taylor expansion of the weight generating function, a particular colour from amongst the denominator parameters may appear multiply, and the flavour labels indicate this multiplicity.

description: Light pollution can be rigorously described in terms of the volume concentration of anthropogenic photons (light quanta) in the terrestrial atmosphere. This formulation, consistent with the basic physics of the emission, scattering and absorption of light, allows one to express light pollution levels in terms of particle volume concentrations, in a completely analogous way as it is currently done with other classical pollutants, like particulate matter or molecular contaminants. In this work we provide the explicit conversion equations between the photon volume concentration and the traditional light photometry quantities. This equivalent description of the light pollution levels provides some relevant insights that help to identify artificial light at night as a standard pollutant. It also enables a complementary way of expressing artificial light exposures for environmental and public health research and regulatory purposes.

description: The Conservation Reserve Program (CRP) was created in the 1985 Farm Bill as a program to remove highly erodible and environmentally sensitive land from agricultural production for 10-15 years. Originally viewed as a supply control program it rapidly evolved into a program that met many environmental objectives. In 2007 SD had 729,397 acres of CRP contracts expired, which was nearly 47% of the 1.56 million acres enrolled. The policy environment in late 2006 and most of 2007 consisted of CRP program offers for renewals or extensions (2-5 years) of many CRP contracts against a backdrop of escalating crop prices and economic incentives to return expiring contract acres to agricultural production. Overall there was a net reduction of 263.7 thousand acres (17%) of CRP land in SD. Economic conditions in 2008 are markedly different. Commodity prices are nearly double that of a year ago and many producers view putting CRP acres back into production as a viable, profitable option. Approximately 508,000 acres of CRP contract will be expiring from 2008-2010, 420,700 from 2011-2013, and an additional 364,600 acres between 2014-2023 (FSA). In 2006 and 2007, the FSA made enrollment offers for 10-15 years or contract extension offers of 2–5 years for many CRP contracts expiring from 2007–2010. For SD contracts expiring in 2007, a total of 52.7 thousand CRP acres were re-enrolled and 370.6 thousand acres were accepted in contract extensions. The remaining 306 thousand acres of expired contracts were not re-enrolled or extended and likely converted to crop or forage production. In addition, there were 38.8 thousand CRP acres added through new enrollments. Just as enrolling these acres into the program had significant negative impacts on revenue generation in the farm and rural economy in SD, putting these acres back into production will also have significant positive impacts on the economy of the state. The objective of this study is to estimate the economic impacts that could occur as some of these CRP acres are converted back to production for three different regions within the state. The effect of converting some of the CRP land to grazing is not examined in this analysis. Only the effects of converting CRP land to crop production is analyzed here.

description: The study examines the factors the factors that influence Fort Valley State University students’ willing to purchase transgenic meat. Results show that respondents who said they read labels when shopping were more likely to purchase transgenic meat. Results also suggest that respondents who trust scientists to tell them the truth about transgenic meat were more likely to purchase transgenic meat. Respondents who identified themselves as sophomores, however, were less likely to consume transgenic meat.

description: The Deep Extragalactic Evolutionary Probe (DEEP) is a series of spectroscopic surveys of faint galaxies, targeted at the properties and clustering of galaxies at redshifts z ~ 1. We present the redshift catalog of the DEEP 1 GSS pilot phase of this project, a Keck/LRIS survey in the HST/WFPC2 Groth Survey Strip. The redshift catalog and data, including reduced spectra, are publicly available through a Web-accessible database. The catalog contains 658 secure galaxy redshifts with a median z=0.65, and shows large-scale structure walls to z = 1. We find a bimodal distribution in the galaxy color-magnitude diagram which persists to z = 1. A similar color division has been seen locally by the SDSS and to z ~ 1 by COMBO-17. For red galaxies, we find a reddening of only 0.11 mag from z ~ 0.8 to now, about half the color evolution measured by COMBO-17. We measure structural properties of the galaxies from the HST imaging, and find that the color division corresponds generally to a structural division. Most red galaxies, ~ 75%, are centrally concentrated, with a red bulge or spheroid, while blue galaxies usually have exponential profiles. However, there are two subclasses of red galaxies that are not bulge-dominated: edge-on disks and a second category which we term diffuse red galaxies (DIFRGs). The distant edge-on disks are similar in appearance and frequency to those at low redshift, but analogs of DIFRGs are rare among local red galaxies. DIFRGs have significant emission lines, indicating that they are reddened mainly by dust rather than age. The DIFRGs in our sample are all at z>0.64, suggesting that DIFRGs are more prevalent at high redshifts; they may be related to the dusty or irregular extremely red objects (EROs) beyond z>1.2 that have been found in deep K-selected surveys.

description: Food quality from a consumer perspective includes sanitary aspects as well as nutrition, but also taste, aspect, integrity and the particularity of products. But quality at the consumer level can only be achieved if quality is respected throughout the whole chain. An analysis is undertaken using as a case study Portuguese producers of two types of PDO beef. Results, using multivariate data analysis, show that the main attributes for a quality beef at the producers` level are: feeding, finishing, specific quality, age at slaughter, breed and transport. Results also suggest that producers have distinct quality perceptions on PDO beef.

description: We report detection of oscillations in brightness temperature, size, and horizontal velocity of three small bright features in the chromosphere of a plage/enhanced-network region. The observations, which were taken with high temporal resolution (i.e., 2-sec cadence) with the Atacama Large Millimeter/submillimeter Array (ALMA) in Band 3 (centred at 3 mm; 100 GHz), exhibit three small-scale features with oscillatory behaviour with different, but overlapping, distributions of period on the order of, on average, $90 \pm 22$ s, $110 \pm 12$ s and $66 \pm 23$ s, respectively. We find anti-correlations between perturbations in brightness temperature and size of the three features, which suggest the presence of fast sausage-mode waves in these small structures. In addition, the detection of transverse oscillations (although with a larger uncertainty) may suggest as well the presence of Alfvénic oscillations which are likely representative of kink waves. This work demonstrates the diagnostic potential of high-cadence observations with ALMA for detecting high-frequency magnetohydrodynamic waves in the solar chromosphere. Such waves can potentially channel a vast amount of energy into the outer atmosphere of the Sun.

On Standard and Taste. Wittgenstein and Aesthetic Judgment

description: The question of aesthetic judgment is related to a lot of paradoxes that have marked sustainably the reflection on arts, and even arts as such during their modern history. These paradoxes have found a first formulation, apparently clear, in the very famous Hume's essay: "On the standard of taste", but without to lead to a real resolution. In this paper, I would like to approach the question of Hume by starting from what Wittgenstein suggested about aesthetic judgment in his Cambridge lectures. To this end, I will try to give a wittgensteinian reading of Hume's essay, in order to show that though the question of aesthetic judgment makes certainly sense, the way of considering it - like the way Kant shall consider it later - can be regarded as typical of difficulties Wittgenstein tried to overcome in his investigations on rules. By giving an alternative formulation to this question, we should be able to examine differently the problems of the aesthetic judgment, to underline more precisely the originality of Wittgenstein's approach, and perhaps to better grasp what are its consequences, not only for a better comprehension of the relationship between Wittgenstein’s philosophy and art, but for the type of perplexity to which we must face everytime we meet the paradox inherent to the question of aesthetic appreciation as such: how can we conceive the very idea of a standard involving a normative meaning without making to faint what gives to a work of art its value. We shall see that Wittgenstein’s suggestions, though their contribution to a better understanding of this question is still affected by some ambiguities, are to be reconsidered under the light of his anti-essentialism, and that these ambiguities can be dissipated by dissociating, on one hand, what belongs to his own tastes or to his related thoughts and on the other hand what we can conceive through the ways which were opened by his philosophy beyond his personal inclinations. Despite what gives to the sphere of Wittgenstein's artistic interests its limited character; despite also what drives his attention towards another kind of problems, it may well be that his thought cast a bright light on current artistic practices and therefore on the questions they ask to philosophy.
