description: We consider the Abelian sandpile model (ASM) on the large square lattice with a single dissipative site (sink). Particles are added by one per unit time at random sites and the resulting density of particles is calculated as a function of time. We observe different scenarios of evolution depending on the value of initial uniform density (height) $h_0=0,1,2,3$. During the first stage of the evolution, the density of particles increases linearly. Reaching a critical density $ρ_c(h_0)$, the system changes its behavior sharply and relaxes exponentially to the stationary state of the ASM with $ρ_s=25/8$. We found numerically that $ρ_c(0)=ρ_s$ and $ρ_c(h_0>0) \neq ρ_s$. Our observations suggest that the equality $ρ_c=ρ_s$ holds for more general initial conditions with non-positive heights. In parallel with the ASM, we consider the conservative fixed-energy Abelian sandpile model (FES). The extensive Monte-Carlo simulations for $h_0=0,1,2,3$ have confirmed that in the limit of large lattices $ρ_c(h_0)$ coincides with the threshold density $ρ_{th}(h_0)$ of FES. Therefore, $ρ_{th}(h_0)$ can be identified with $ρ_s$ if the FES starts its evolution with non-positive uniform height $h_0 \leq 0$.

description: We explore the origin of a population of distant companions (~1000 - 5000 AU) to Class I protostellar sources recently found by Connelley and co-workers, who noted that the companion fraction diminished as the sources evolved. Here we present N-body simulations of unstable triple systems embedded in dense cloud cores. Many companions are ejected into unbound orbits and quickly escape, but others are ejected with insufficient momentum to climb out of the potential well of the cloud core and associated binary. These loosely bound companions reach distances of many thousands of AU before falling back and eventually being ejected into escapes as the cloud cores gradually disappear. We use the term orphans to denote protostellar objects that are dynamically ejected from their placental cloud cores, either escaping or for a time being tenuously bound at large separations. Half of all triple systems are found to disintegrate during the protostellar stage, so if multiple systems are a frequent outcome of the collapse of a cloud core, then orphans should be common. Bound orphans are associated with embedded close protostellar binaries, but escaping orphans can travel as far as ~0.2 pc during the protostellar phase. The steep climb out of a potential well ensures that orphans are not kinematically distinct from young stars born with a less violent pre-history. The identification of orphans outside their heavily extincted cloud cores will allow the detailed study of protostars high up on their Hayashi tracks at near-infrared and in some cases even at optical wavelengths.

description: We examine the exclusion limits set by the CDF and D0 experiments on the Standard Model Higgs boson mass from their searches at the Tevatron in the light of large theoretical uncertainties on the signal and background cross sections. We show that when these uncertainties are consistently taken into account, the sensitivity of the experiments becomes significantly lower and the currently excluded mass range $M_H=158$-175 GeV would be entirely reopened. The necessary luminosity required to recover the current sensitivity is found to be a factor of two higher than the present one.

description: The study of plant-environment interactions is a multidisciplinary research field. With the emergence of quantitative large-scale and high-throughput techniques, amount and dimensionality of experimental data have strongly increased. Appropriate strategies for data storage, management, and evaluation are needed to make efficient use of experimental findings. Computational approaches of data mining are essential for deriving statistical trends and signatures contained in data matrices. Although, current biology is challenged by high data dimensionality in general, this is particularly true for plant biology. Plants as sessile organisms have to cope with environmental fluctuations. This typically results in strong dynamics of metabolite and protein concentrations which are often challenging to quantify. Summarizing experimental output results in complex data arrays, which need computational statistics and numerical methods for building quantitative models. Experimental findings need to be combined by computational models to gain a mechanistic understanding of plant metabolism. For this, bioinformatics and mathematics need to be combined with experimental setups in physiology, biochemistry, and molecular biology. This review presents and discusses concepts at the interface of experiment and computation, which are likely to shape current and future plant biology. Finally, this interface is discussed with regard to its capabilities and limitations to develop a quantitative model of plant-environment interactions.
Leaving Children Behind: Urban Education, Class Politics, and the Machines of Transnational Capitalism

description: In what follows, I want to explore the basis for telling a different kind of story about urban school reform, one that is less hopeful in a naïve sense, but that nevertheless does not abandon hope altogether. The hope is that an honest appraisal of what I call the machines of urban schooling can lead to a new democratic counter-hegemonic movement in American education and public life that offers a new "commonsense," a new way of "thinking" about the urban school crisis and responding to it. I focus on telling the story of a project in democratic educational renewal in a high school in Cincinnati, Ohio, with which I was involved in the mid-1990s as part of a school-college collaborative.

description: Class, defined as a "social category that can explain inequalities of power and wealth in the 'free world'", has become increasingly relevant for interpreting the modern portrait of capitalism. As a conceptual category, which designates a relationship of exploitation, it is "indissociable from class conflict, from the specific historical struggle of social groups divided by unequal property relations". Further, youth as a social category typified by age are also implicated in class struggles through their constant subjugation to the imagery and needs of capital flows. This is made clear by the United Nation's declaration that "more than one billion young people in the developing world are now living in conditions of severe deprivation" as a result of globalized trade and a decrease in 'aid' packages.

title: Robust Signal Processing for Landmine Detection with Forward-Looking Radar
Creators: name: Pambudi, Afief Dias
Publisher: name: UNSPECIFIED
Year: 2021

description: Landmines and other unexploded ordnance are one of the greatest curses in modern times, the legacies of war continuing to pose threats to civilians many years after a conflict has ended. They limit freedom of movement and deny access to basic human needs, which hinder post-conflict reconstruction efforts and the implementation of the sustainable development goals of a country. Detection and clearance of landmines is a very risky operation, which requires high standards on technology and methodology. This PhD thesis is dedicated to the problem of landmine detection using forward-looking ground penetrating radar in rough surface environments. Robust signal processing techniques are developed, which offer a guaranteed performance of landmine detection with the forward-looking radar. A multi-view imaging approach is used in which tomographic radar images are obtained from multiple viewpoints of the investigation area. An approach based on a simple threshold and likelihood-ratio test is first examined for multi-view image fusion and detection. The imaging of a complex scene containing nine plastic and metallic targets is considered. The detection problem is defined as a test between a null (mines absent) and an alternative (mines present) hypothesis. A parametric family of distribution models is employed to obtain nominal distributions of the pixel intensity of the radar image under both hypotheses. The nominal distribution models are then used for fusion schemes based on the likelihood-ratio test detector. In a robust approach, uncertainty distribution models under both hypotheses are considered. The detector is designed to be robust against the deviations of distributions. Two density bands are constructed within which the corresponding probability density functions of feasible distributions are assumed to lie. The detector is then designed such that it minimizes the maximum error probability for all possible density pairs within the two bands. The reason behind following a robust minimax approach is that accurate estimation of the distribution, given the varying nature of the interrogated environment, is highly challenging. The robust techniques overcome this issue since they do not need an accurate initial estimate and are guaranteed to perform well over a set of feasible distributions. The design of the detector is further extended by accounting for the statistical dependency between multiple radar images from different viewpoints of the investigation area. Different copula density functions are investigated in terms of their effectiveness in incorporating dependence between multi-view images into the test statistics. It is shown that incorporating statistical dependence with a well-selected copula model improves the test performance of both non-robust and robust techniques, which affirms the benefit of the implementation.

description: Hydrogen produced from the photocatalytic splitting of water is one of the reliable alternatives to replace the polluting fossil and the radioactive nuclear fuels. Here, we provide unequivocal evidence for the existence of blue- and red-shifting O$-$H covalent bonds within a single water molecule adsorbed on MgO surface as a result of asymmetric displacement polarizabilities. The adsorbed H-O-H on MgO gives rise to one weaker H-O bond, while the other O-H covalent bond from the same adsorbed water molecule compensates this effect with a stronger bond. The weaker bond (nearest to the surface), the interlayer tunneling electrons and the silver substrate are shown to be the causes for the smallest dissociative activation energy on MgO monolayer. The origin that is responsible to initiate the splitting mechanism is proven to be due to the changes in the polarizability of an adsorbed water molecule, which are further supported by the temperature-dependent static dielectric constant measurements for water below the first-order electronic-phase transition temperature.

description: This paper examines the challenges that States face in times of emergency as regards their constitutional framework, the imposition of restrictive measures such as lockdowns and the challenging balance to uphold and fulfil human rights obligations and the rule of law. Bulgaria has responded to the COVID-19 pandemic with the promulgation of the Law of the State of Emergency in March 2020. The State powers in emergency circumstances are not unlimited. The legal framework of the Bulgarian public health emergency is analyzed through the dual lens of constitutional limitations and the Article 15 ECHR derogation regime. The work provides a comparative analysis of the procedural notification practice of various States under the ECHR and ICCPR. The derogation regime and relevant principles such as proportionality and margin of appreciation are thoroughly examined. States should strike the proportionate balance to protect public health and apply the widest possible array of human rights protections.

Root canal dentin erosion following different irrigation protocols
Creators: name: Magnusson, Michael
Publisher: name: University of British Columbia
Year: 2021

description: Objectives: It has been previously shown that root dentin erosion increases if sodium hypochlorite (NaOCl) is used again following final ethylenediaminetetraacetic acid (EDTA). The purpose of this study is to quantitatively examine the erosion of root dentin when alternating these irrigants during instrumentation. Methods: Eight extracted teeth were instrumented to size #40/04, sequentially from #15/04, using Vortex Blue rotary files (Dentsply Tulsa Dental, Tulsa, OK). Teeth were then randomly divided into four groups based on irrigation protocol as follows: Group 1: negative controls, irrigated with saline throughout the instrumentation process and as a final rinse. Group 2: 6% NaOCl was used between files at a flow rate of 5mL/min for 15 seconds. Final irrigation was 2 minutes 6% NaOCl followed by 2 minutes 17% EDTA. Group 3: Same protocol as group 2, plus an additional rinse with 6% NaOCl (2 minutes, 5mL/min) after EDTA. Group 4: Alternating irrigation using NaOCl and EDTA, each for 15 seconds between files during instrumentation. A final rinse was carried out alternating NaOCl, EDTA and NaOCl for 15 seconds each. All teeth were then sectioned into 1mm disks and the dentin element content was analyzed by continuous line scanning up to 300 µm from the canal lumen using energy-dispersive X-ray spectroscopy. Results: Statistically significant differences in atomic percentages of carbon, oxygen and calcium were observed between groups. Group 4 had significantly lower atomic percentages of calcium and significantly higher atomic percentages of carbon than both group 1 and group 2. Significantly lower calcium was also observed in group 3 compared to group 1 while higher levels of carbon and oxygen were observed in group 3 compared to group 2. A trend toward lower levels of calcium and phosphorus was seen in group 4 compared to group 3, however differences were not statistically significant. Conclusion: Alternating NaOCl and EDTA throughout instrumentation resulted in dentin composition with the lowest percentages of Ca and P, indicating higher potential for root dentin erosion.

description: The spinor variety is cut out by the quadratic Wick relations among the principal Pfaffians of an n x n skew-symmetric matrix. Its points correspond to n-dimensional isotropic subspaces of a 2n-dimensional vector space. In this paper we tropicalize this picture, and we develop a combinatorial theory of tropical Wick vectors and tropical linear spaces that are tropically isotropic. We characterize tropical Wick vectors in terms of subdivisions of Delta-matroid polytopes, and we examine to what extent the Wick relations form a tropical basis. Our theory generalizes several results for tropical linear spaces and valuated matroids to the class of Coxeter matroids of type D.

This occurs as the giant component disintegrates, characterized by a power law with critical exponent $β\simeq 0.65$ is independent of the balance between excitatory and inhibitory neurons and indicates that the degree distribution is gaussian rather than scale free

description: The extraordinary properties of graphene make it a very promising material for use in optoelectronics. However, this is still a nascent field, where some basic properties of the electromagnetic field in graphene must be explored. Here we report on the fields radiated by a nanoemitter lying on a graphene sheet. Our results show that this field presents a rich dependence on both frequency, distance to the source and dipole orientation. This behavior is attributed to distinct peculiarities on the density of electromagnetic states in the graphene sheet and the interaction between them. The field is mainly composed of an core region of high-intensity electromagnetic field, dominated by surface plasmons, and an outer region where the field is practically the same it would be for an emitter in vacuum. Within the core region, the intensity of the electric field is several orders of magnitude larger than what it would be in vacuum. Importantly, the size of this core region can be controlled thorough external gates, which opens up many interesting applications in, for instance, surface optics and spectroscopy. Additionally, the large coupling between nanoemitters and surface plasmons makes graphene sheets a propitious stage for quantum-optics, in which the interaction between quantum objects could be externally tailored at will.

The Accelerating Growth of Online Tagging Systems

description: Research on the growth of online tagging systems not only is interesting in its own right, but also yields insights for website management and semantic web analysis. Traditional models that describing the growth of online systems can be divided between linear and nonlinear versions. Linear models, including the BA model (Brabasi and Albert, 1999), assume that the average activity of users is a constant independent of population. Hence the total activity is a linear function of population. On the contrary, nonlinear models suggest that the average activity is affected by the size of the population and the total activity is a nonlinear function of population. In the current study, supporting evidences for the nonlinear growth assumption are obtained from data on Internet users' tagging behavior. A power law relationship between the number of new tags (F) and the population (P), which can be expressed as F ~ P ^ gamma (gamma > 1), is found. I call this pattern accelerating growth and find it relates the to time-invariant heterogeneity in individual activities. I also show how a greater heterogeneity leads to a faster growth.

description: Roderick Coover and Scott Rettberg reflect on the cultural values, political debates, power structures and architectures of exploitation underlying much of contemporary digital culture. As digital artists and collaborators, they also identify aesthetic reactions that actually combat what they critique. But for this to happen, we need literary works that are themselves produced, and actively circulating within digital environments.

description: Dusty debris discs around main sequence stars are thought to be the result of continuous collisional grinding of planetesimals in the system. The majority of these systems are unresolved and analysis of the dust properties is limited by the lack of information regarding the dust location.vThe Herschel DUNES key program is observing 133 nearby, Sun-like stars (<20 pc, FGK spectral type) in a volume limited survey to constrain the absolute incidence of cold dust around these stars by detection of far infrared excess emission at flux levels comparable to the Edgeworth-Kuiper belt (EKB). We have observed the Sun-like star HD 207129 with Herschel PACS and SPIRE. In all three PACS bands we resolve a ring-like structure consistent with scattered light observations. Using α Boötis as a reference point spread function (PSF), we deconvolved the images, clearly resolving the inner gap in the disc at both 70 and 100 μm. We have resolved the dust-producing planetesimal belt of a debris disc at 100 μm for the first time. We measure the radial profile and fractional luminosity of the disc, and compare the values to those of discs around stars of similar age and/or spectral type, placing this disc in context of other resolved discs observed by Herschel/DUNES.

description: Despite several indirect confirmations of the existence of dark matter, the properties of a new dark matter particle are still largely unknown. Several experiments are currently searching for this particle underground in direct detection, in space and on earth in indirect detection and at the LHC. A confirmed signal could select a model for dark matter among the many extensions of the standard model. In this paper we present a short review of the public codes for computation of dark matter observables.

description: We introduce a method for solving the problem of an externally controlled electron spin in a quantum dot interacting with host nuclei via the hyperfine interaction. Our method accounts for generalized (non-unitary) evolution effected by external controls and the environment, such as coherent lasers combined with spontaneous emission. As a concrete example we develop the microscopic theory of the dynamics of nuclear-induced frequency focusing, as first measured in Science 317, 1896 (2007); we find that the nuclear relaxation rates are several orders of magnitude faster than those quoted in that work.

On the Binding Energy Parameter $λ$ of Common Envelope Evolution

description: The binding energy parameter $λ$ plays an important role in common envelope (CE) evolution. Previous works have already pointed out that $λ$ varies throughout the stellar evolution, though it has been adopted as a constant in most of the population synthesis calculations. We have systematically calculated the binding energy parameter $λ$ for both Population I and Population II stars of masses $1-20 M_{\sun}$, taking into account the contribution from the internal energy of stellar matter. We present fitting formulae for $λ$ that can be incorporated into future population synthesis investigations. We also briefly discuss the possible applications of the results in binary evolutions.

description: Il presente lavoro di diploma vede come tema la didattica del testo letterario del canone tradizionale, nello specifico la narrativa di formazione, fruita attraverso l’approccio Tell me di Aidan Chambers, in linea con i principi del Piano di studio della scuola ticinese in rapporto alla competenza trasversale dello sviluppo personale e al contesto di formazione generale delle sclete e dei progetti personali. La classe di applicazione è una III, pertanto va ad incontrare necessità formative specifiche per gli allievi del secondo biennio. Il metodo utilizzato per condurre la mia ricerca è l’approccio ermeneutico di Aidan Chambers, proposto nel contesto di un percorso di interventi in aula sulla lettura di brani selezionati, interpretazione degli stessi e discussione condotta in classe sulla base di domande stimolo riadattate per le mie specifiche esigenze didattiche dalla lista delle domande proprie dell’approccio Tell me. Il carattere del mio lavoro di diploma è applicativo: ho potuto trarre dati di tipo qualitativo circa la validità dell’analisi e della discussione e tematizzazione a cui la classe è approdata e all’apprezzamento relativo alla lettura/ascolto in termini di piacere per la lettura e appagamento di un bisogno di relazione con il prossimo e con il testo. Le principali implicazioni dei risultati a cui sono giunta attestano che la didattica attraverso il testo letterario apporta un plusvalore in termini educativi e relazionali rispetto alla didattica per mezzo di brani ed autori più contemporanei e che l’approccio Tell me rappresenta una modalità molto valida per creare situazioni di apprendimento accattivanti, stimolanti ed efficaci.

description: We show that b-tau Yukawa unification can be successfully implemented in the constrained minimal supersymmetric model and it yields the stop co-annihilation scenario.The lightest supersymmetric particle is a bino-like dark matter neutralino, which is accompanied by a 10-20% heavier stop of mass ~ 100-330 GeV. We highlight some benchmark points which show a gluino with mass ~0.6 - 1.7 TeV, while the first two family squarks and all sleptons have masses in the multi- TeV range.

A Program-Level Approach to Revising Logic Programs under the Answer Set Semantics
Creators: name: Delgrande, James P.
Publisher: name: arXiv
Year: 2010
Subjects: subject: Artificial Intelligence (cs.AI)
subject: FOS: Computer and information sciences

description: An approach to the revision of logic programs under the answer set semantics is presented. For programs P and Q, the goal is to determine the answer sets that correspond to the revision of P by Q, denoted P * Q. A fundamental principle of classical (AGM) revision, and the one that guides the approach here, is the success postulate. In AGM revision, this stipulates that A is in K * A. By analogy with the success postulate, for programs P and Q, this means that the answer sets of Q will in some sense be contained in those of P * Q. The essential idea is that for P * Q, a three-valued answer set for Q, consisting of positive and negative literals, is first determined. The positive literals constitute a regular answer set, while the negated literals make up a minimal set of naf literals required to produce the answer set from Q. These literals are propagated to the program P, along with those rules of Q that are not decided by these literals. The approach differs from work in update logic programs in two main respects. First, we ensure that the revising logic program has higher priority, and so we satisfy the success postulate; second, for the preference implicit in a revision P * Q, the program Q as a whole takes precedence over P, unlike update logic programs, since answer sets of Q are propagated to P. We show that a core group of the AGM postulates are satisfied, as are the postulates that have been proposed for update logic programs.
