Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The effects of gas pressure gradients on the motion of solid grains in the solar nebula substantially enhances the efficiency of forming protoplanetary cores in the standard core accretion model in 'hybrid' scenarios for gas/ice giant planet formation. Such a scenario is enhanced core accretion which results from Epstein-drag induced inward radial migration of mm-sized grains and subsequent particle subdisk gravitational instability needed to build up a population of 1 km planetesimals. Solid/gas ratios can be enhanced by nearly $\sim 10\times$ over those in Minimum Mass Solar Nebula (MMSN) in the outer solar nebula (a $>$ 20 AU), increasing the oligarchic core masses and decreasing formation timescales for protoplanetary cores. A 10 $M_{\oplus}$ core can form on $\sim 10^{6}-10^{7}$ year timescales at 15 - 25 AU compared to $\sim 10^{8}$ years in the standard model,alleviating the major problem plaguing the core accretion model for gas/ice giant planet formation.

The emergence of sustainability : culture shift and the transformation of worldviews through social learning
Creators: name: Gonzalez, Julian Matias
Publisher: name: University of British Columbia
Year: 2011

description: There is an abundant literature describing the sustainability problems our planet is facing, ranging from the loss of biodiversity and ecosystems that are necessary to support healthy communities to the everexpanding population, social inequality and worldwide increase of poverty. Many of the existing sustainability initiatives attempt to address these issues by creating new technologies, increasing efficiency, and modifying systems of governance. While many of these approaches are promising, their success fundamentally depends on their acceptance by society. I argue that this aspect is frequently overlooked and more attention should be paid to the human dimensions of sustainability development. The approach presented in this thesis uses a more comprehensive approach and highlights the importance that consciousness, culture, and values play in shaping our views of reality and therefore our understanding of sustainability. I explore the all-quadrant, all-level approach of integral theory (Wilber, 1996b) as an overarching framework to discuss these ideas. The all-quadrants concept of internal and external, individual and collective realities is used to outline the multiple dimensions of sustainability. I apply the all-levels concept of human development to explain the multitude of conceptions, behaviours and attitudes that individual mindsets and collective worldviews have towards sustainability. One of the main challenges for sustainability is overcoming the values crisis in modern society and it is argued that in order to achieve this, a cultural shift is required if we hope to address today's pressing socio-ecological problems. To this effect a framework of social learning has been developed based on the synthesis of the literature that serves to guide this cultural shift. To illustrate the potential of this framework a case study was conducted in a natural resource conservation and forestry course at the University of British Columbia. The results are encouraging and demonstrate the potential of social learning for shifting individual mindsets towards ones that are more inclined towards cultivating sustainable livelihoods.

description: In recent years, various deep learning techniques have been exploited in side channel attacks, with the anticipation of obtaining more appreciable attack results. Most of them concentrate on improving network architectures or putting forward novel algorithms, assuming that there are adequate profiling traces available to train an appropriate neural network. However, in practical scenarios, profiling traces are probably insufficient, which makes the network learn deficiently and compromises attack performance.
 In this paper, we investigate a kind of data augmentation technique, called mixup, and first propose to exploit it in deep-learning based side channel attacks, for the purpose of expanding the profiling set and facilitating the chances of mounting a successful attack. We perform Correlation Power Analysis for generated traces and original traces, and discover that there exists consistency between them regarding leakage information. Our experiments show that mixup is truly capable of enhancing attack performance especially for insufficient profiling traces. Specifically, when the size of the training set is decreased to 30% of the original set, mixup can significantly reduce acquired attacking traces. We test three mixup parameter values and conclude that generally all of them can bring about improvements. Besides, we compare three leakage models and unexpectedly find that least significant bit model, which is less frequently used in previous works, actually surpasses prevalent identity model and hamming weight model in terms of attack results.

For $X^3$ a simple, thick hyperbolic P-manifold of dimension 3, we show that certain subsets of the boundary at infinity of the universal cover of $X^3$ are characterized topologically. Straightforward consequences include a version of Mostow rigidity, as well as quasi-isometric rigidity for these spaces.

description: The work argues that post-war political and economic conditions led to the rejection of the pre-war policy of autarchy in favour of an open economy. This decision had implications not only for external trade and payments, but more importantly for the very structure of the Italian industrial sector. The authors show how the performance of this emerging industrial structure was conditioned by the performance of the prices of imported raw material, and subsequently semi-manufactured industrial inputs and the prices at which the final products could be sold in export markets. This so-called industrial terms of trade is combined with the previously existing explanations of post-war growth period that does not have to rely on “miracles” as explanation. JEL: F10, N34, O14

description: A group of rats were given 1.6 g/kg intraperitoneal (IP) injections of either saline or ethanol on 16 successive conditioning days (CD's). During each two-day period of the 16-day sequence, the rats received saline on one day in a specifically "saline-paired" environment and ethanol on the next day in an "ethanol-paired" environment. Visual, olfactory, auditory, and tactile manipulations were utilized to create these two different environments. In order to determine the conditioned response to ethanol, rats were given saline in "ethanol-paired" environments at the end of the 16-day sequence. SMA on this day was compared to that of the previous saline day and the following day, which was specifically conducted as a "reconditioning day". In determining conditioned tolerance, rats were next given ethanol in the "saline-paired" environment. SMA on this day was again compared to that of the previous and following ethanol day in the "ethanol-paired" environment. A robust conditioned response was found as the rats showed much higher SMA on the conditioned response test day than on regular saline conditioning days. Although the rats showed less SMA on the conditioned tolerance test day than on regular ethanol conditioning days, the difference was not statistically significant. However, this non-significant trend in the predicted direction was interpreted as a result of an insufficient number of subjects, or due to unpredictable variations of individual animal physiology in response to ethanol CNS depressant effects. The observation of the conditioned increase in SMA provides further support for the theory that conditioned responses to depressant drugs are usually in a direction opposite to the actual drug effect.

description: Quarkonium physics is a fundamental field of research to get a better understanding of quantum chromodynamics - the theory of the strong interaction. Quarkonia are bound states of the heavy charm or bottom quark and their respective antiquarks. The complexity of understanding the quarkonium production mechanism has given rise to various theoretical models. The Large Hadron Collider (LHC) reaches unprecedented collision energies and has already significantly contributed to understanding the experimental side of the quarkonium puzzle. The CMS detector is well suited to study the polarization of promptly-produced chi_cJ states, using data taken in proton-proton collisions in 2012 at a center of mass energy of 8 TeV. This thesis describes the general strategy of the analysis, focusing on the most important input parameters, namely the muon detection efficiencies. Single muon detection efficiencies as well as muon pair correlations are presented.

description: Some advocates of financial development have made a powerful case against government control of interest rates by resting their case on the discriminatory effects of credit rationing. In doing so they have confused the issues by attributing to government controls the consequences which normally flow from credit rationing by banks even in the absence of legal control. The object of the article is to clear up the confusion by distinguishing more clearly between two kinds of credit rationing, “bank rationing” and “government rationing”. JEL: E51, E43

description: XMM-Newton observations of the polar SDSSJ155331.12+551614.5 reveal that all the X-ray flux emerges at energies less than 2 keV. The best fit to the spectrum is with a thermal plasma with kT=0.8 keV plus a 20-90 ev black body, yielding a thermal X-ray luminosity of 8-9.5E28 ergs/s. The low temperature and X-ray luminosity, together with the lack of variation of the X-ray flux during the observations, are all consistent with an extremely low accretion rate that puts the system in the bombardment regime of accretion, rather than accretion involving a standoff shock. It is likely that the observed X-rays originate from the M dwarf secondary star, thus providing a base activity level for late main sequence stars in close binaries. SDSSJ132411.57+032050.5 is detected by XMM-Newton at the faint EPIC pn count rate of 0.0012 c/s, giving an upper limit to the X-ray luminosity of 7E28 ergs/s for a distance of 300 pc, which is also consistent with the above scenario.

description: We prove that the stability condition for Fano manifolds defined by Saito-Takahashi, given in terms of the sum of the Ding invariant and the Chow weight, is equivalent to the existence of anticanonically balanced metrics. Combined with the result by Rubinstein-Tian-Zhang, we obtain the following algebro-geometric corollary: the $δ_m$-invariant of Fujita-Odaka satisfies $δ_m >1$ if and only if the Fano manifold is stable in the sense of Saito-Takahashi, establishing a Hilbert-Mumford type criterion for $δ_m >1$. We also extend this result to the Kähler-Ricci $g$-solitons and the coupled Kähler-Einstein metrics, and as a by-product we obtain a formula for the asymptotic slope of the coupled Ding functional in terms of multiple test configurations.

description: We report experimental and numerical results on the growth of a super stable heap (SSH). Such a regime appears for flows in a thin channel and for high flow rate : the flow occurs atop a nearly static heap whose angle is stabilized by the flowing layer at its top and the side wall friction. The growth of the static heap is investigated in this paper. A theoretical analysis inspired by the BRCE formalism predicts the evolution of the growth process, which is confirmed by both experiments and numerical simulations. The model allows us to link the characteristic time of the growth to the exchange rate between the "moving" and "static" grains. We show that this rate is proportional to the height of the flowing layer even for thick flows. The study of upstream traveling waves sheds new light on the BCRE model.

description: Inhibitory activity of the biocontrol bacterial strain Lysobacter capsici AZ78 is related to the production of cyclo(l-Pro-l-Tyr), a 2,5-diketopiperazine with in vitro and in vivo toxic activity against Phytophthora infestans and Plasmopara viticola. Further investigation of culture filtrate organic extracts showed its ability to produce other 2,5-diketopiperazines. They were isolated and identified by spectroscopic (1H NMR and ESIMS) and physic (specific optical rotation) methods as cyclo(l-Pro-l-Val), cyclo(d-Pro-d-Phe), cyclo(l-Pro-l-Leu), and cyclo(d-Pro-l-Tyr). When tested against the phytopathogenic Gram-positive bacterium Rhodococcus fascians LMG 3605, cyclo(l-Pro-l-Val) showed a toxic activity similar to chloramphenicol at a comparable concentration. Overall, these data suggest that 2,5-diketopiperazines represent a class of metabolites characterizing the metabolome of L. capsici AZ78. Furthermore, the toxic activity showed by cyclo(l-Pro-l-Val) against R. fascians LMG 3605 broaden the spectrum activity of 2,5-diketopiperazines against phytopathogenic microorganisms enforcing their potential development as biopesticides.
Inferring spin tilts at formation from gravitational wave observations of binary black holes: Interfacing precession-averaged and orbit-averaged spin evolution

description: Two important parameters inferred from the gravitational wave signals of binaries of precessing black holes are the spin tilt angles, i.e., the angles at which the black holes' spin axes are inclined with respect to the binary's orbital angular momentum. The LIGO-Virgo parameter estimation analyses currently provide spin tilts at a fiducial reference frequency, often the lowest frequency used in the data analysis. However, the most astrophysically interesting quantities are the spin tilts when the binary was formed, which can be significantly different from those at the reference frequency for strongly precessing binaries. The spin tilts at formally infinite separation are a good approximation to the tilts at formation in many formation channels and can be computed efficiently for binary black holes using precession-averaged evolution. Here, we present a new code for computing the tilts at infinity that combines the precession-averaged evolution with orbit-averaged evolution at high frequencies and illustrate its application to GW190521 and other binary black hole detections from O3a. We have empirically determined the transition frequency between the orbit-averaged and precession-averaged evolution to produce tilts at infinity with a given accuracy. We also have regularized the precession-averaged equations in order to obtain good accuracy for the very close-to-equal-mass binary parameters encountered in practice. This additionally allows us to investigate the singular equal-mass limit of the precession-averaged expressions, where we find an approximate scaling of $1/(1 - q)$ with the mass ratio $q$.

description: Originally studied for their suitability to store information compactly, memristive networks are now being analysed as implementations of neuromorphic circuits. An extremely high number of elements is thus mandatory. To surpass the limited achievable connectivity - due to the featuring size - exploiting self-assemblies has been proposed as an alternative, in turn posing more challenges. In an attempt for offering insight on what to expect when characterizing the collective electrical response of switching assemblies, in this work, networks of memristive elements are simulated. Collective electrical behaviour and maps of resistance states are characterized upon different electrical stimuli. By comparing the response of homogeneous and heterogeneous networks, we delineate differences that might be experimentally observed when the number of memristive units is scaled up and disorder arises as an inevitable feature.

description: In the observations of the economy as it moved towards the great collapse of the winter of 1932-33, the elements of what happens when the market system breaks down are revealed. The work looks at the successful interventions of the 1960s and 70s, detailing how incoherence can be constrained and a semblance of coherence imposed. The author argues that although the processes that make for debt deflations and over-indebtedness are persistent characteristics of capitalist economies, the actual result of these processes in observable behaviour depends upon the institutional context and the force of policy interventions. Moreover, economic administration cannot be reduced to a simple routine. JEL: F34, E61

description: In this work, we present the effect of a probe string on the complexity of a black hole according to the CA (Complexity equals action) conjecture on Horndeski's gravity. In our system, we consider a particle moving on the boundary of black hole spacetime in ($2+1$)-dimensions. To obtain a dual description, we need to insertion a fundamental string on the bulk spacetime. The effect of this string is given by the Nambu-Goto term. For the Nambu-Goto term, we can analyze the time development of this system, which is affected by the parameters of Horndeski's gravity. In our case, we show some interesting complexity properties for this gravity.

Im weiteren Verlauf werden Grundlagen zur Berechnung von Strukturen erläutert, zusammengefasst und ein Vergleich mit den in der Literatur vorherrschenden mikromechanischen Berechnungen gezogen. Auf die Theorie des Langzeitverhaltens von Kunststoffen wird ebenso eingegangen wie auf das Verhalten von Faser-Verbund-Werkstoffen unter Langzeitbelastung. In Bezug auf das viskoelastische Verhalten der Kunststoffmatrix wurde ein technisch einfacher Prüfstand entwickelt, der das Langzeitverhalten von gewickelten Faser-Kunststoff-Rohren untersucht. Es werden die mechanischen Grundlagen zum Prüfstand als auch der Prüfstand selbst jeweils bei der Biegeprüfung und der Torsionsprüfung anschaulich erklärt. In weiterer Folge werden Ausgangsmaterialien und die Wickelwinkel der Proben definiert. Die Fertigung der FKV-Rohre mittels der am Institut verwendeten Wickelmaschine wird beschrieben. Die kreuzungsfrei gewickelten Proben werden in dieser Arbeit auf ihr Kriechverhalten untersucht und die Rohre mit verschiedenen Wickelwinkeln untereinander verglichen. Die dazugehörigen Versuchsergebnisse werden aufgearbeitet, grafisch dargestellt und Erkenntnisse über das vom Faserwinkel abhängige Kriechverhalten zusammengefasst.
description: With regard to the importance of fiber-reinforced polymers (FRP) and their widespread fields of application the concept of elasto-kinematics and its interrelation with FRPs will be the main focus of the thesis on hand. In the further course of the thesis the calculation basics of complete FRP structures will be outlined and summarized, including a short comparison with micromechanical calculations predominant in the corresponding literature available. The work will cover theories of general long-term behavior of synthetic materials as well as the behavior of FRPs experiencing sustained loading. In relation to the viscoelastic behavior of the synthetic matrix, a testing station monitoring and analyzing the long-term behavior of winded FRP-pipes has been developed. Its mechanical basics as well as the testing station at both the bending testing and the torsional testing will be explained in a detailed way. Subsequently, the starting materials and winding-angles of the probes will be defined. The manufacturing of the FRP-pipes using the department-s winding-machine will be described. The creeping behavior of the cross-free winded probes is examined and pipes with different winding angles are compared. The obtained results are presented and graphically displayed to gain knowledge about how the material's creeping behavior is correlated to the fiber's angle.

description: Multi-TeV spectra of Mkn 501 and other BL Lac objects exhibit the high energy cutoffs predicted to be the result of intergalactic annihilation interactions, primarily with IR photons having the flux level determined by various astrophysical observations. After correcting for such intergalactic absorption, these spectra can be explained within the framework of synchrotron self-Compton emission models. Stecker and Glashow have shown that the existence of this annihilation via electron-positron pair production puts strong constriants on Lorentz invariance violation. Such constriants have important implications for some quantum gravity and large extra dimension models. A much smaller amount of Lorentz invariance violation has potential implications for understanding the spectra of ultrahigh energy cosmic rays.

description: This study aimed to investigate the existence of economies of scale and cost inefficiency in citrus production in São Paulo State. To this end, primary data was collected from a random sample of 98 citrus farms. Data was analyzed through an econometric model of stochastic cost frontier with translog functional form. It was found the existence of significant economies of scale for low/medium production levels (up to 40 thousand boxes). Diseconomies of scale for production emerge for production larger than 300 thousand boxes. Minimum average cost is between 150,000 and 300,000 boxes regarding production levels. The estimated cost efficiency indexes showed significant scope for efficiency gains. The most cost efficient farms in the sample are capital intensive. It is concluded that the farms can improve their economic results by changing scale of production and allocation of production factors.

description: Usnic acid has anti-cancer activity, however, low solubility and toxicity limit the potential. To investigate biological activity of usnic acid derivatives, enantiopure derivatives were synthesised by reacting usnic acid with ethylenediamine, which yielded one dimer product ((+)-1), and two tetra cyclic compounds ((+)-2 and (-)-2). The products were characterised with NMR, and evaluated in vitro in human colon cancer cell line Caco-2 by cell count, phase-contrast microscopy, MTT-assay, measurement of DNA content and cell cycle distribution. All compounds tested showed cytostatic effect in Caco-2 cells, but each compound had a distinct cellular effect. Compound (+)-1 showed anti-proliferative activity by increasing the percentage of cells in S-phase with 25% compared to the control. Compounds (+)-2 and (-)-2 induced paraptosis, but only compound (+)-2 modulated cell cycle distribution by accumulating cells in G2/M-phase by 47% and reduced DNA content by 60%. All compounds express interesting cellular and potential anti-proliferative activity.
The macroeconomic theory of Vera C. Lutz
Creators: name: GRAZIANI, A.
Publisher: name: PSL Quarterly Review
Year: 2013
Subjects: subject: Vera Lutz, macroeconomic equilibrium, structural dualism, Southern Italy
subject: B31

description: Vera Lutz was an economist with wide-ranging interests, including credit theory, the theory of the firm, economic development theory and labour market analysis. Although there are several good reasons for examining and discussing her ideas in the field of macroeconomic equilibrium, however, there has thus far been little debate on these aspects of her thinking. In fact, there was only a short-lived debate in 1962, when Ackley and Spaventa wrote article criticising her ideas on the development of Southern Italy, dealing more with facts than theoretical framework. The debate on her thinking has since remained restricted to her theory of structural dualism. The author offers a reevaluation of Lutz’ work, and in particular the problem of macroeconomic equilibrium. JEL: B31

description: A bar-joint framework $(G,p)$ in a (non-Euclidean) real normed plane $X$ is the combination of a finite, simple graph $G$ and a placement $p$ of the vertices in $X$. A framework $(G,p)$ is globally rigid in $X$ if every other framework $(G,q)$ in $X$ with the same edge lengths as $(G,p)$ arises from an isometry of $X$. The weaker property of local rigidity in normed planes (where only $(G,q)$ within a neighbourhood of $(G,p)$ are considered) has been studied by several researchers over the last 5 years after being introduced by Kitson and Power for $\ell_p$-norms. However global rigidity is an unexplored area for general normed spaces, despite being intensely studied in the Euclidean context by many groups over the last 40 years. In order to understand global rigidity in $X$, we introduce new generalised rigid body motions in normed planes where the norm is determined by an analytic function. This theory allows us to deduce several geometric and combinatorial results concerning the global rigidity of bar-joint frameworks in $X$.

Publisher: name: PSL Quarterly Review
Year: 2013
Subjects: subject: Italy, Vera Lutz, post-war experience, balance of payments, monetary policy
subject: B31, F32, E52

description: The present work contains an overview of economic developments in Italy between the end of the war and the stabilisation measures of September 1947 in order to provide a concise factual background to examine Vera Lutz’s analysis of this period. The main elements of Lutz’s analytical framework at the beginning of the 1950s are briefly recalled. A review of her critical assessment of Italy’s immediate postwar experience and of the policies adopted, especially in the monetary and balance-of-payments areas is provided. JEL: B31, F32, E52

On the first Townsend coefficient at high electric field
Creators: name: Davydov, Yu. I.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Instrumentation and Detectors (physics.ins-det)
subject: FOS: Physical sciences

description: Based on the simplified approach it is shown and experimentally confirmed that gas gain in wire chambers at very low pressure becomes higher on thicker wires at the same applied high voltage. This is a consequence of the fact that the first Townsend coefficient at high reduced electric field depends almost entirely on the mean free path of electrons.

description: In spite of the fact that the legal reserve generates several environmental benefits, it causes opportunity costs for the producer. This paper uses the Zou, Ang and Poh (2006)’s model to estimate the opportunity cost of holding the legal reserve inside each farm in São Paulo and Mato Grosso States (Brazil) in 1995 and 2006 (which correspond to the last two agricultural census). The methodology takes the average producer by municipality and adjusts the number of municipalities according to Paiva (2007 and 2008)’s method. Among the results, the following are highlighted: (1st) both technical efficiency and environmental technical efficiency are small in both analyzed states, but they have grown up between the two analyzed years; (2nd) the opportunity cost of legal reserve is lower in São Paulo compared to that in Mato Grosso (R$ 23,878 and R$ 48,353 per farm, respectively, in 2006), but the cost per hectare is 2.22 times higher in São Paulo in relation to Mato Grosso; (3rd) after displaying these costs on maps, some similarities and dissimilarities appeared among neighboring cities, which would be explored in the future by using spatial econometric techniques. New research might also be conducted about this paper’s issue as new dataset becomes available.

Biodiversity within dry forests of the interior of British Columbia : the role of aspen and stand structure
Creators: name: Oaten, Dustin Kyle
Publisher: name: University of British Columbia
Year: 2011

description: The dry interior forests of British Columbia are composed of contiguous coniferous forests dominated by Douglas-fir (Pseudotsuga menziesii), with a small portion consisting of trembling aspen (Populus tremuloides). These aspen trees are of particular interest as there is evidence that they may support a relatively abundant and diverse faunal community. However, this potential has not been extensively explored within these forests. Two bioindicator taxa, small mammals and cavity-nesting birds, were investigated within aspen stands near Kamloops, British Columbia, Canada during 2005 and 2006, and were compared to neighbouring Douglas-fir and mixedwood stands. Seven thousand ninety seven captures of 12 small mammal species were made during 15,761 trap nights, with 48% of captures within aspen stands. Seven species were numerically dominant within these stands including the deer mice (Peromyscus maniculatus), southern red-backed vole (Clethrionomys gapperi), long-tailed vole (Microtus longicaudus), montane vole (Microtus montanus), meadow vole (Microtus pennsylvanicus), and the northwestern chipmunk (Tamias amoenus). Eight stand level attribute variables were highly correlated with total small mammal abundance: percent aspen, total plant cover, number of grass species, snag density (stems/ha), CWD volume (m³/ha), plant richness, and shrub and herb cover. Fourteen cavity-nesting bird species were detected 1541 times during 288 point count surveys, with 48% of detections within aspen stands. Four species dominated the counts: three weak secondary cavity excavators and a single primary cavity excavator. The total abundance of cavity-nesting bird species was correlated with total volume of CWD (m³/ha), snag volume (m³/ha), snag density (stems/ha), downed CWD volume (m³/ha) and percent aspen. Overall, the pure stands of aspen supported the largest numbers and diversity of small mammals and birds; these results highlight the importance of aspen stands as they may serve as biodiversity 'hotspots' within dry interior British Columbia forests. Forest managers should incorporate the maintenance of these stands into their long-term management plans.
