description: We show that the recently formulated Equivalence Principle (EP) implies a basic cocycle condition both in Euclidean and Minkowski spaces, which holds in any dimension. This condition, that in one-dimension is sufficient to fix the Schwarzian equation [6], implies a fundamental higher dimensional Moebius invariance which in turn univocally fixes the quantum version of the Hamilton-Jacobi equation. This holds also in the relativistic case, so that we obtain both the time-dependent Schroedinger equation and the Klein-Gordon equation in any dimension. We then show that the EP implies that masses are related by maps induced by the coordinate transformations connecting different physical systems. Furthermore, we show that the minimal coupling prescription, and therefore gauge invariance, arises quite naturally in implementing the EP. Finally, we show that there is an antisymmetric two-tensor which underlies Quantum Mechanics and sheds new light on the nature of the Quantum Hamilton-Jacobi equation.

subject: data approach, Ricardian model

description: One of the important targets of government policy in agriculture sector is to increase the cultivation area and production level of strategic goods such as oilseeds due to the wide dependence on imports in the supply chain of vegetable oil. This study aimed to assess the impacts of climatic factors and government policies (both uncontrollable and controllable factors) on soybean and canola cultivation area and land rental in some provinces of Iran using data collected over 2001-2016. For this purpose, Ricardian model and panel data approach were applied. The results revealed the great influence of rainfall and temperature changes on soybean and canola cultivation area in Iran. Guaranteed prices for soybean and canola had a positive significant effect on the crops cultivation area. On the other, adoption of the self-sufficiency policy for wheat production through increasing the guaranteed price impeded development of oilseed cultivation area. Unlike for canola, increased wheat cultivation area had, however, no statistically significant influence on soybean cultivation area. Overall, decreased precipitation and air temperature warming are anticipated to negatively impact oilseeds cultivation area and land rent

description: Ba(Fe$_{1/2}$Nb$_{1/2}$)O$_3$ (BFN) ceramics are considered to be promising for technological applications owing to their high dielectric constant over a wide range of temperatures. However, there exists considerable discrepancy over the structural details. We address this discrepancy through a combined x-ray diffraction at room temperature and neutron powder diffraction measurements in the range from 5K up to room temperature, supplemented by a comparative analysis of the earlier reported structures. Our study reveals a cubic structure with space group Pm$\bar{3}$m at all measured temperatures. Further, the x-ray near edge structure and the extended x-ray absorption fine structure studies on the local environment of the Fe ions is consistent with the cubic symmetry. An appropriate value of $U$ for DFT+$U$ calculations is obtained by comparison with x-ray absorption spectroscopy, which agrees well with the earlier reported electronic properties.

The CWKB approach to non-reflecting potential and cosmological implications

Year: 2002
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We discuss the method of calculating the reflection coefficient using complex trajectory WKB (CWKB) approximation. This enables us to give an interpretation of non-reflecting nature of the potential under certain conditions and clarify some points, reported incorrectly elsewhere [vs:ejp] for the potential $U(x)=-U_0cosh^2(x/a)$. We show that the repeated reflectios between the turning points are essential, which most authors overlooked, in obtaining the non-reflecting c ondition. We find that the considered repeated reflection paths are in conformity with Bogolubov transformation technique. We discuss the implications of the results when applied to the particle production scenario, considering $x$ as a time variable and also stress the cosmological implications of the result with reference to radiation domonated and de Sitter spacetime.

Faster provable sieving algorithms for the Shortest Vector Problem and the Closest Vector Problem on lattices in $\ell_p$ norm
Creators: name: Mukhopadhyay, Priyanka
Publisher: name: arXiv
Year: 2019
Subjects: subject: Data Structures and Algorithms (cs.DS)
subject: FOS: Computer and information sciences

description: In this work, we give provable sieving algorithms for the Shortest Vector Problem (SVP) and the Closest Vector Problem (CVP) on lattices in $\ell_p$ norm ($1\leq p\leq\infty$). The running time we obtain is better than existing provable sieving algorithms. We give a new linear sieving procedure that works for all $\ell_p$ norm ($1\leq p\leq\infty$). The main idea is to divide the space into hypercubes such that each vector can be mapped efficiently to a sub-region. We achieve a time complexity of $2^{2.751n+o(n)}$, which is much less than the $2^{3.849n+o(n)}$ complexity of the previous best algorithm. We also introduce a mixed sieving procedure, where a point is mapped to a hypercube within a ball and then a quadratic sieve is performed within each hypercube. This improves the running time, especially in the $\ell_2$ norm, where we achieve a time complexity of $2^{2.25n+o(n)}$, while the List Sieve Birthday algorithm has a running time of $2^{2.465n+o(n)}$. We adopt our sieving techniques to approximation algorithms for SVP and CVP in $\ell_p$ norm ($1\leq p\leq\infty$) and show that our algorithm has a running time of $2^{2.001n+o(n)}$, while previous algorithms have a time complexity of $2^{3.169n+o(n)}$.

Year: 1994
Subjects: subject: 580

description: Scorzonera Laciniata gehört zu den in Mitteleuropa stark gefährdeten Gefäßpflanzenarten, von denen infolge ihrer Seltenheit kaum Angaben zur Ökologie vorliegen. Bei der Untersuchung ihrer Populationen in Nordwestdeutschland stellte sich heraus, daß die niedrigwüchsige Art vor allem in Ökotonen auf tonigen, zumeist salzbeeinflußten Böden wächst. Überlebensfähige Populationen finden sich nur noch auf sekundären Salzstellen, wo die Art im Übergangsbereich schütterer Dauco-Melilotion- oder Convolvulo-Agropyrion-Bestände zu vegetationsfreien Flächen wächst. Sehr häufig ist sie mit Puccinellia distans und Lepidium ruderale vergesellschaftet. An zwei Wuchsorten ist sie mit Gypsophila perfoliata, Gypsophila scorzonerifolia, Suaeda maritima, Atriplex rosea und Atriplex tatarica vergesellschaftet. Hier wurden Atriplex tatarica, Gypsophila perfoliata und Gypsophila scorzonerifolia erstmals für Niedersachsen belegt.
description: Scorzonera Laciniata is one of the most endangered species in central Europe. Because of its seldomness, almost no releves are known. By investigating the populations in northwestern Germany it was found, that this small species grows especially on salt affected clays. Surviving populations are only to be found on secondary inland saline sites, where the species grows in transitional zones from sparse stands of Dauco-Melilotion and/or Convolvulo-Agropyrion to vegetation-free areas. Very often it is associated with Lepidium ruderale and Puccinellia distans. At two locations it is associated with Atriplex tatarica, Gypsophila perfoliata and Gypsophila scorzonerifolia, which are recorded for the very first time in Lower Saxony.

Subjects: subject: 580

description: Die Ruderalvegetation der Altmark und des östlich angrenzenden Elbtals wurde 1990 mit dem Ziel untersucht, den gegenwärtigen Zustand zu erfassen und zu dokumentieren. Das flachwellige pleistozäne Tiefland steht unter subkontinentalem Klimaeinfluß; die Niederschlagsmengen überschreiten 600 mm nicht. Die Altmark bildet heute den nördlichen Teil des Bundeslandes Sachsen-Anhalt; sie gehörte 40 Jahre zur DDR. Die reiche Ruderalvegetation weist große Ähnlichkeit zu derjenigen anderer kontinental getönter Sandgebiete des östlichen Mitteleuropa auf. Im Verhältnis zum westlich unmittelbar angrenzenden Niedersachsen fällt der große Neophytenreichtum sowie der wesentlich höhere Flächenanteil der Ruderalvegetation insgesamt auf. Verbreitete Neophyten sind z.B. Amaranthus retroflexus, Artemisia annua (Elbe), Bidens frondosa (Elbe), Atriplex acuminata, A. oblongifolia, Chenopodium strictum, Diplotaxis muralis, D. tenuifolia, Kochia scoparia ssp. densiflora, Lycium barbarum, Robinia pseudacacia, Salsola kali ssp. ruthenica und Sisymbrium loeselii. Insbesondere Atriplex oblongifolia wanderte entlang der Straßen bis unmittelbar an die ehemalige Grenze; mit weiterer Ausbreitung nach Westen ist in naher Zukunft zu rechnen, was z.B. auch für Kochia scoparia ssp. densiflora entlang der Eisenbahnstrecken zu erwarten ist.
description: The ruderal vegetation of the Altmark (Germany) and the adjacent Elbe valley to the est were investigated in 1990 in order to record and document their present status. The undulating diluvial lowlands have a subcontinental climate with annual precipitation below 600 mm. The Altmark forms the northern part of the state Saxony-Anhalt, which for 40 years belonged to the GDR. The rich ruderal vegetation shows a great similarity to those of other continental sandy areas of easterncentral Europe. In inverse proportion to the directly adjacent Lower Saxony, the great richness in neophytes
and the far greater ruderal areas as a whole are noticeable. Common neophytes are, for example, Amaranthus retroflexus, Artemisia annua (Elbe), Bidens frondosa (Elbe), Atriplex acuminata, A. oblongifolia, Chenopodium strictum, Diplotaxis muralis, D. tenuifolia, Kochia scoparia ssp. densiflora, Lycium barbarum, Robinia pseudacacia, Salsola kali ssp. ruthenica and Sisymbrium loselii. Atriplex oblongifolia, especially migrates along roads up to the former border, and further spread to the west in the near future can be expected. The same is very possible for Kochia scoparia ssp. densiflora along railways.

description: The purpose of this research is to apply technical analysis of Sutte Indicator in stock trading which will assist in the investment decision making process i.e. buying or selling shares. This research takes data of "A" on the Indonesia Stock Exchange(IDX or BEI) 29 November 2006 until 20 September 2016 period. To see the performance of Sutte Indicator, other technical analysis are used as a comparison, Simple Moving Average (SMA) and Moving Average Convergence/Divergence (MACD). To see a comparison of the level of reliability prediction, the stock data were compared using the mean absolute deviation (MAD), mean of square error (MSE), and mean absolute percentage error (MAPE). The result of this research is that Sutte Indicator can be used as a reference in predicting stock movements, and if it is compared to other indicator methods (SMA and MACD) via MAD, MSE, and MAPE, the Sutte Indicator has a better level of reliability.

description: An energetic justification of a thermal component during inflation is given. The thermal component can act as a heat reservoir which induces thermal fluctuations on the inflaton field system. We showed previously that such thermal fluctuations could dominate quantum fluctuations in producing the initial seeds of density perturbations. A Langevin-like rate equation is derived from quantum field theory which describes the production of fluctuations in the inflaton field when acted upon by a simple modeled heat reservoir. In a certain limit this equation is shown to reduce to the standard Langevin equation, which we used to construct "Warm Inflation" scenarios in previous work. A particle physics interpretation of our system-reservoir model is offered.

Stratonovich-Weyl quantizer, star-products and Wigner functionals are obtained in field and oscillator variables. Abelian gauge theory is particularly intriguing since Wigner functional is factorized into a physical part and other one containing the constraints only. Some effects of non-trivial topology within deformation quantization formalism are also considered.

To Be or Not to Be Property: Community Attitudes towards the Legal Status of Animals

Publisher: name: Monash University

Subjects: subject: Law
subject: FOS: Law

description: This thesis explores community attitudes towards the legal status of animals as property. To measure the extent to which the community agrees with the legal categorisation of animals as property, empirical research was undertaken in a small sector of the Australian community. The results of this study indicate that the property status of at least some animals is not consistent with contemporary attitudes. This thesis concludes that to reflect variegated attitudes towards animals, a nuanced approach to the legal status of animals is required - one that allows for different types of animals to be categorised or treated differently.

description: In this paper, we consider equilibrium strategies under Volterra processes and time-inconsistent preferences embracing mean-variance portfolio selection (MVP). Using a functional Itô calculus approach, we overcome the non-Markovian and non-semimartingale difficulty in Volterra processes. The equilibrium strategy is then characterized by an extended path-dependent Hamilton-Jacobi-Bellman equation system under a game-theoretic framework. A verification theorem is provided. We derive explicit solutions to three problems, including MVP with constant risk aversion, MVP for log returns, and a mean-variance objective with a linear controlled Volterra process. We also thoroughly examine the effect of volatility roughness on equilibrium strategies. Numerical experiments demonstrate that trading rules with rough volatility outperform the classic counterparts.

description: In this paper, we introduce the Preselection Bandit problem, in which the learner preselects a subset of arms (choice alternatives) for a user, which then chooses the final arm from this subset. The learner is not aware of the user's preferences, but can learn them from observed choices. In our concrete setting, we allow these choices to be stochastic and model the user's actions by means of the Plackett-Luce model. The learner's main task is to preselect subsets that eventually lead to highly preferred choices. To formalize this goal, we introduce a reasonable notion of regret and derive lower bounds on the expected regret. Moreover, we propose algorithms for which the upper bound on expected regret matches the lower bound up to a logarithmic term of the time horizon.
High order amplitude equation for steps on creep curve

description: We consider a model proposed by one of the authors for a type of plastic instability found in creep experiments which reproduces a number of experimentally observed features. The model consists of three coupled non-linear differential equations describing the evolution of three types of dislocations. The transition to the instability has been shown to be via Hopf bifurcation leading to limit cycle solutions with respect to physically relevant drive parameters. Here we use reductive perturbative method to extract an amplitude equation of up to seventh order to obtain an approximate analytic expression for the order parameter. The analysis also enables us to obtain the bifurcation (phase) diagram of the instability. We find that while supercritical bifurcation dominates the major part of the instability region, subcritical bifurcation gradually takes over at one end of the region. These results are compared with the known experimental results. Approximate analytic expressions for the limit cycles for different types of bifurcations are shown to agree with their corresponding numerical solutions of the equations describing the model. The analysis also shows that high order nonlinearities are important in the problem. This approach further allows us to map the theoretical parameters to the experimentally observed macroscopic quantities.

The struggle with biodiversity conservation
Creators: name: Schuerholz, Goetz
Publisher: name: The University of British Columbia
Year: 2009

description: Biodiversity conservation in the area of environment management has become the new buzzword of this decade. Widely used but little understood, it continues to cause confusion and misgivings. It is expected that new legislation and policies will soon be in place requiring biodiversity conservation to be addressed in Environmental Impact Assessments and land use development projects. This paper describes a first attempt to develop an objective method to qualify and quantify biodiversity for the Line Creek coal properties and leases in the Elk Valley of B.C. Corresponding baseline data are provided through Line Creek's comprehensive biophysical inventories, complemented through additional fieldwork in 1994. The overall objective was to facilitate comparison of ecological entities in terms of biodiversity. Based on a vegetation map of 1 : 20 000, the Map Units identified as "macrohabitats" were rated via a Biodiversity Index developed for this purpose. Key elements of the biodiversity index are flora and fauna as living ecosystem components. To do justice to specific habitat requirements of live organisms, six component indices were assessed. The sum of the component indices provides the overall value of the Biodiversity Index with the assumption that attached values are additive. The numerical rating of component indices with an overall numerical value of the Biodiversity Index permits a relatively objective comparison habitat types. This method is far from being perfect. The most serious drawback is the lack of information and unbalanced information in particular with respect to invertebrates and lower plant species. The objective of this presentation is to stimulate a discussion on a topic which cannot any longer be ignored.

description: Mohsin Hamid is, along with Salman Rushdie, one of the most powerful „postcolonial voices‟ in British literature to employ elements of magical realism in order to fictionally recreate a hectic contemporary history which seems to be moving faster than ever. People desperately flee from violent civil wars, seeking refuge, and politics of inclusion flourishes in Europe in response. Against this background, drawing inspiration from various violent events, like the Syrian Civil War, the fall of Mosul and the Yemeni Civil War, as well as from his personal migrant experience, Hamid publishes his fourth novel, Exit West, equally personal and political as his other novels, most notably, The Reluctant Fundamentalist, dedicated to the events of 9/11. The paper aims to analyse Exit West from the perspective of this relation between the personal and the political, tracing the role of magical realism in opening the doors towards the painfully realistic construction of otherness.
A model of gravitation with global U(1)-symmetry
Creators: name: Ivanov, Michael A.
Publisher: name: arXiv
Year: 2002
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: It is shown that an embedding of the general relativity $4-$space into a flat $12-$space gives a model of gravitation with the global $U(1)-$symmetry and the discrete $D_{1}-$one. The last one may be transformed into the $SU(2)-$symmetry of the unified model, and the demand of independence of $U(1)-$ and $SU(2)-$transformations leads to the estimate $\sin^{2}θ_{min}=0,20$ where $θ_{min}$ is an analog of the Weinberg angle of the standard model.

description: We find in experiments a linear dependence of ionization irradiation-induced degradations on pre-irradiation values of the input bias current in bipolar devices with simple input stages. The dependence is found to generally exist in all studied cases of different device types and different irradiation conditions. A unique behavior of the energy distribution of the interface states ($D_{it}$) under irradiation is suggested as the origin of the observed phenomenon: the generation of interface traps through the depassivation of Si-H bonds located near the pre-irradiation interface traps displays a $D_{it}$ as an enlarge of the initial $D_{it}$ and results in the general linear dependence. A more accurate damage prediction method by using the pre-irradiation values is proposed based on the observed phenomenon.

Establishment of trees and shrubs on mined land in the subalpine region of Alberta

description: The Alberta Research Council has conducted a surface mine reclamation research program at the operations of Smoky River Coal Limited near Grande Cache, Alberta since 1972. The overall objective of this study is to develop and refine costeffective methods of establishing and maintaining a vegetative cover that is in harmony with adjacent undisturbed areas. A program to introduce trees and shrubs to the area was undertaken concurrently with the establishment of grasses and legumes. Due to the lack of seedlings available at the time for planting above an elevation of 1100 m, a cone collection program was undertaken to obtain seed for production of lodgepole pine (Pinus contorta var. latifolia), white spruce (Picea glauca), and engelmann spruce (Picea engelmanniil. Cuttings of willow (Salix spp.), balsam poplar (Populus balsamifera), and root cuttings of aspen (Populus tremuloides) were rooted in the greenhouse prior to planting. Willow cuttings were also collected and directly planted in the field. Most of the trees and shrubs produced were planted in areas having an established grass, or grass and legume cover. Container grown conifer seedlings were superior to bare root stock in terms of survival and growth rate. Survival rate increased with increasing size of container. Mean annual growth measurements of lodgepole pine and engelmann spruce seedlings in the reclaimed areas and adjacent undisturbed forest indicated that the reconstructed soils will support tree growth that is equivalent to the growth achieved on the natural or undisturbed soils. The willow and alder provided excellent protection for the conifers when the conifers exceeded the height of the grass and legume cover. Frost heaving of container seedlings and limited egress were the major causes of mortality for the conifers. Direct seeding was initiated in the fall of 1983 using seed of pine, spruce, and alder. The results obtained showed that direct seeding is a viable alternative to the use of container or bare root materials for specific locations in a mined area. The research conducted to date indicates that trees and shrubs can become established in reclaimed areas in the subalpine. The methods that are utilized for any given location are dependent on the end land use desired, the time frame allowed, and specific site conditions.

description: Let $f$ be a nonnegative integer valued function on the vertex set of a graph. A graph is \textbf{strictly $f$-degenerate} if each nonempty subgraph $Γ$ has a vertex $v$ such that $\mathrm{deg}_Γ(v) < f(v)$. In this paper, we define a new concept, strictly $f$-degenerate transversal, which generalizes list coloring, signed coloring, DP-coloring, $L$-forested-coloring, and $(f_{1}, f_{2}, \dots, f_{s})$-partition. A \textbf{cover} of a graph $G$ is a graph $H$ with vertex set $V(H) = \bigcup_{v \in V(G)} X_{v}$, where $X_{v} = \{(v, 1), (v, 2), \dots, (v, s)\}$; the edge set $\mathscr{M} = \bigcup_{uv \in E(G)}\mathscr{M}_{uv}$, where $\mathscr{M}_{uv}$ is a matching between $X_{u}$ and $X_{v}$. A vertex set $R \subseteq V(H)$ is a \textbf{transversal} of $H$ if $|R \cap X_{v}| = 1$ for each $v \in V(G)$. A transversal $R$ is a \textbf{strictly $f$-degenerate transversal} if $H[R]$ is strictly $f$-degenerate. The main result of this paper is a degree type result, which generalizes Brooks' theorem, Gallai's theorem, degree-choosable result, signed degree-colorable result, and DP-degree-colorable result. We also give some structural results on critical graphs with respect to strictly $f$-degenerate transversal. Using these results, we can uniformly prove many new and known results. In the final section, we pose some open problems.

Internal displacement and the education of school-aged children in Colombia

description: Internal displacement in Colombia is a country-wide phenomenon that has affected almost five percent of the country's population or 14% of the country's rural population. Colombia's violent conflict has not reached yet a post-conflict stage since no peace agreement has been reached between the State and violent actors. This makes an analysis of the effects of displacement and of the state-led initiatives relating to it, such as the Familias en Accion para la poblacion desplazada , highly relevant to the current status of this humanitarian crisis. Using a unique data set from Colombia, the National Survey of Displaced Households (ENHD) performed in 2004, this thesis examines the educational situation of displaced children and studies the impact of various forces, including government policy, on the schooling of displaced children. The dissertation investigates the following questions: 1) What are the main factors determining the enrollment of internally displaced children at the destination municipalities? 2) What is the effect associated with the participation in the Familias en Accion for IDPs Program on enrollment? 3) What is the prevalence of school overage among internally displaced children and what are its main determinants? With respect to the first research question, the results show that children who are members of a female-headed household have a lower probability of being enrolled in school. Conversely, children whose head of household is literate have a higher probability of enrollment. The research is also able to examine the impact of how long families have been displaced. The results show that after a year, children's probability of enrollment increases significantly, bouncing upwards relative to the period immediately following displacement. Finally, the results show that higher household income is associated with greater enrollment, but in a nonlinear way: if a household belongs to the first three income quintiles the probability of enrollment does not increase significantly, but for the fourth and fifth income quintiles, the probability of enrollment increases by 10 and 12 percentage points evaluated at the mean. The second research question examines the effect of the Familias en Accion for IDPs Program on enrollment using a difference in differences (DID) model. The results obtained using the DID approach show that children whose families are aid beneficiaries are more likely to be enrolled in schools, holding other things constant. The third research question in the dissertation looks at the prevalence - and determinants - of school overage among internally displaced children. It is estimated that there are two years of overage after displacement which comes from the fact that this population is forced to leave their places of origin and resettle in other destinations, time during which children are not be able to enroll in school thus affecting their attainment.
Guided Visual Exploration of Relations in Data Sets

description: Efficient explorative data analysis systems must take into account both what a user knows and wants to know. This paper proposes a principled framework for interactive visual exploration of relations in data, through views most informative given the user's current knowledge and objectives. The user can input pre-existing knowledge of relations in the data and also formulate specific exploration interests, which are then taken into account in the exploration. The idea is to steer the exploration process towards the interests of the user, instead of showing uninteresting or already known relations. The user's knowledge is modelled by a distribution over data sets parametrised by subsets of rows and columns of data, called tile constraints. We provide a computationally efficient implementation of this concept based on constrained randomisation. Furthermore, we describe a novel dimensionality reduction method for finding the views most informative to the user, which at the limit of no background knowledge and with generic objectives reduces to PCA. We show that the method is suitable for interactive use and is robust to noise, outperforms standard projection pursuit visualisation methods, and gives understandable and useful results in analysis of real-world data. We provide an open-source implementation of the framework.

description: The present paper proposes an alternative to the well-established notion that postcolonial literature is still a marginal literary category in the twenty-first century, trying to demonstrate that, in fact, postcolonial voices have long occupied a forefront position in the reception of the critics and general public alike, gradually turning their books into both successful marketable products and ideological weapons. Reasons may vary from the readers’ mere interest in becoming acquainted with the culture of a perpetual other that has moved closer in space after the fall of the colonial empires to guilt for the past treatment of these territories and of their peoples. From the radical approaches to postcolonialism in the 1950s-1960s, which have now become classical theoretical texts, to the cultural and historical affirmation in the 1980s and reaffirmation of identity, in the context of rising Islamophobia after 9/11, writers labelled as postcolonial now push the boundaries, heading straight to the centre of the Western Canon. Asserting their identity, either in `je suis l’autre’ fashion or by highlighting their hybridity, the literary voices of the East are no longer just an exotic niche of English literature. A good case in point is Mohsin Hamid, Pakistani-British author whose novels, nominated for important Western literary prizes, provide a fresh perspective of what means to be the other in the eyes of the West.
