description: Using methods developed by Franke, we obtain algebraic classification results for modules over certain symmetric ring spectra ($S$-algebras). In particular, for any symmetric ring spectrum $R$ whose graded homotopy ring $π_*R$ has graded global homological dimension 2 and is concentrated in degrees divisible by some natural number $N \geq 4$, we prove that the homotopy category of $R$-modules is equivalent to the derived category of the homotopy ring $π_*R$. This improves the Bousfield-Wolbert algebraic classification of isomorphism classes of objects of the homotopy category of $R$-modules. The main examples of ring spectra to which our result applies are the $p$-local real connective $K$-theory spectrum $ko_{(p)}$, the Johnson-Wilson spectrum E(2), and the truncated Brown-Peterson spectrum $BP<1>$, for an odd prime $p$.

A vision of whales : creating a whale research program for individuals who are blind or visually impaired
Creators: name: Kent, Lynn Andrea
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this research project was to explore how field experience can be used to increase understanding and researcher behaviours in young adults who are blind or visually impaired. This study probed effective teaching methods and solutions to accessibility issues through high-level participation in a field ecology research setting involving marine mammals. The weeklong program was executed in a pre-existing long-term gray whale ecology research site in Clayoquot Sound, British Columbia. Four research questions guided the overall planning of the program. The concentration of effort was applied to adapting the field site and equipment in order for students to use and access the resources during planned multisensory activities. Three post-secondary students spent a week in the field becoming active marine mammal researchers. Data for this study were gathered through a variety of qualitative methods including vocabulary checklists, journal writing, a group case study and questionnaires. The results of this program have implications for educational opportunities by highlighting how addressing and offering learning tools that appeal to a variety of learners can create new and vital opportunities for students who are visually impaired.
“Got You!”: Automatic Vandalism Detection in Wikipedia
with Web-based Shallow Syntactic-Semantic Modeling
Creators: name: McKeown, Kathleen

Publisher: name: Columbia University
Year: 2010
Subjects: Computer science

description: Discriminating vandalism edits from  non-vandalism edits in Wikipedia is a  challenging task, as ill-intentioned edits  can include a variety of content and be  expressed in many different forms and  styles. Previous studies are limited to rule-based methods and learning based  on lexical features, lacking in linguistic  analysis. In this paper, we propose a  novel Web-based shallow syntactic-semantic modeling method, which utilizes Web search results as resource and  trains topic-specific n-tag and syntactic n-gram language models to detect vandalism. By combining basic task-specific  and lexical features, we have achieved
high F-measures using logistic boosting  and logistic model trees classifiers, surpassing the results reported by major  Wikipedia vandalism detection systems.
A novel sampling theorem on the sphere

description: We develop a novel sampling theorem on the sphere and corresponding fast algorithms by associating the sphere with the torus through a periodic extension. The fundamental property of any sampling theorem is the number of samples required to represent a band-limited signal. To represent exactly a signal on the sphere band-limited at L, all sampling theorems on the sphere require O(L^2) samples. However, our sampling theorem requires less than half the number of samples of other equiangular sampling theorems on the sphere and an asymptotically identical, but smaller, number of samples than the Gauss-Legendre sampling theorem. The complexity of our algorithms scale as O(L^3), however, the continual use of fast Fourier transforms reduces the constant prefactor associated with the asymptotic scaling considerably, resulting in algorithms that are fast. Furthermore, we do not require any precomputation and our algorithms apply to both scalar and spin functions on the sphere without any change in computational complexity or computation time. We make our implementation of these algorithms available publicly and perform numerical experiments demonstrating their speed and accuracy up to very high band-limits. Finally, we highlight the advantages of our sampling theorem in the context of potential applications, notably in the field of compressive sampling.

description: We show that generic, slow dynamics can occur in the contact process on complex networks with a tree-like structure and a superimposed weight pattern, in the absence of additional (non-topological) sources of quenched disorder. The slow dynamics is induced by rare-region effects occurring on correlated subspaces of vertices connected by large weight edges, and manifests in the form of a smeared phase transition. We conjecture that more sophisticated network motifs could be able to induce Griffiths phases, as a consequence of purely topological disorder.

Learning Intonation Rules for Concept to Speech Generation

Subjects: Information technology

description: In this paper, we report on an effort to provide a general-purpose spoken language generation tool for Concept-to-Speech (CTS) applications by extending a widely used text generation package, FUF/SURGE, with an intonation generation component. As a first step, we applied machine learning and statistical models to learn intonation rules based on the semantic and syntactic information typically represented in FUF/SURGE at the sentence level. The results of this study are a set of intonation rules learned automatically which can be directly implemented in our intonation generation component. Through 5-fold cross-validation, we show that the learned rules achieve around 90% accuracy for break index, boundary tone and phrase accent and 80% accuracy for pitch accent. Our study is unique in its use of features produced by language generation to control intonation. The methodology adopted here can be employed directly when more discourse/pragmatic information is to be considered in the future.

description: In this paper, we describe bow quantifiers can be generated in a text generation system. By taking advantage of discourse and ontological information, quantified expressions can replace entities in a text, making the text more fluent and concise. In addition to avoiding ambiguities between distributive and collective readings in universal quantification generation, we will also show how different scope orderings between universal and existential quantitiers will result in different quantified expressions in our algorithm.

description: Generalized Scidar (GS) measurements taken at the Paranal Observatory in November/December 2007 in the context of a site qualification for the future European Extremely Large Telescope E-ELT are re-calibrated to overcome the bias induced on the CN2 profiles by a not correct normalization of the autocorrelation of the scintillation maps that has been recently identified in the GS technique. A complete analysis of the GS corrected measurements as well as of the corrected errors is performed statistically as well as on individual nights and for each time during all nights. The relative errors of the CN2 profiles can reach up to 60% in some narrow temporal windows and some vertical slabs, the total seeing up to 12% and the total integrated turbulence J up to 21%. However, the statistic analysis tells us that the absolute errors of the median values of the total seeing is 0.06 arcsec (relative error 5.6%), for the boundary seeing 0.05 arcsec (relative error 5.6%) and for the seeing in the free atmosphere 0.04 arcsec (relative error 9%). We find that, in spite of the fact that the relative error increases with the height, the boundary and the free atmosphere seeing contribute in an equivalent way to the error on the total seeing in absolute terms. Besides, we find that there are no correlations between the relative errors and the value of the correspondent seeing. The absolute error of the median value of the isoplanatic angle is 0.13 arcsec (relative error 6.9%).

description: The production of events with multiple high transverse momentum particles including charged leptons and jets is measured, using 1.04 fb-1 of proton-proton collision data recorded by the ATLAS detector during the first half of 2011 at sqrt(s) = 7 TeV. No excess beyond Standard Model expectations is observed, and upper limits on the fiducial cross sections for non-Standard Model production of these final states are set. Using models for string ball and black hole production and decay, exclusion contours are determined as a function of mass threshold and the fundamental gravity scale.

description: Systems that distill information about events from large corpora generally extract sentences that are relevant to a short event query. We present a novel co-training strategy for this task that employs a multidocument news summary corpus featuring 2.5 million unlabeled sentences, thus obviating the need for extensive manual annotation. Our experiments indicate that this technique signiﬁcantly outperforms standard classiﬁcation approaches with linear feature combination on this task. An analysis of our approach under various settings reveals how classiﬁer and parameter choice can be used to control runtime overhead while contributing to an absolute increase of 22% in recall.

description: This paper presents a method for large corpus analysis to semantically classify an entire clause.

Metal-to-insulator transition and electron-hole puddle formation in disordered graphene nanoribbons

description: The experimentally observed metal-to-insulator transition in hydrogenated graphene is numerically confirmed for actual sized graphene samples and realistic impurity concentrations. The eigenstates of our tight-binding model with substitutional disorder corroborate the formation of electron-hole-puddles with characteristic length scales comparable to the ones found in experiments. The puddles cause charge inhomogeneities and tend to suppress Anderson localization. Even though, monitoring the charge carrier quantum dynamics and performing a finite-size scaling of the local density of states distribution, we find strong evidence for the existence of localized states in graphene nanoribbons with short-range but also correlated long-range disorder.

Optimal and Syntactically-Informed Decoding for Monolingual
Phrase-Based Alignment

Subjects: Computer science

description: The task of aligning corresponding phrases across two related sentences is an important component of approaches for natural language problems such as textual inference, paraphrase detection and text-to-text generation. In this work, we examine a state-of-the-art structured prediction model for the alignment task which uses a phrase-based representation and is forced to decode alignments using an approximate search approach. We propose instead a straightforward exact decoding technique based on integer linear programming that yields order-of-magnitude improvements in decoding speed. This ILP-based decoding strategy permits us to consider syntactically-informed constraints on alignments which signiﬁcantly increase the precision of the model.

description: Attempts to use natural language processing (NLP) for text categorization and information retrieval (IR) have had mixed results. Nevertheless, there is a strong intuition that NLP is important, at least for some tasks. In this paper, we discuss a task involving captioned images for which the subject and the predicate are critical. The usefulness of NLP for this task is established in two ways. In addition to the standard method of introducing a new system and comparing its performance with others in the literature, we also present evidence from experiments with human subjects showing that NLP generally improves speed and accuracy.

description: This paper explores the use of a statistical technique known as density estimation to potentially improve the results of text categorization systems which label documents by computing similarities between documents and categories. In addition to potentially improving a system's overall accuracy, density estimation converts similarity scores to probabilities. These probabilities provide confidence measures for a system's predictions which are easily interpretable and could potentially help to combine results of various systems. We discuss the results of three complete experiments on three separate data sets applying density estimation to the results of a TF*IDF/Rocchio system, and we compare these results to those of many competing approaches.
Folding transitions in three-dimensional space with defects

description: A model describing the three-dimensional folding of the triangular lattice on the face-centered cubic lattice is generalized allowing the presence of defects corresponding to cuts in the two-dimensional network. The model can be expressed in terms of Ising-like variables with nearest-neighbor and plaquette interactions in the hexagonal lattice; its phase diagram is determined by the Cluster Variation Method. The results found by varying the curvature and defect energy show that the introduction of defects turns the first-order crumpling transitions of the model without defects into continuous transitions. New phases also appear by decreasing the energy cost of defects and the behavior of their densities has been analyzed.

Characterization of CAP-D2 and CAP-D3 condensin subunits in Arabidopsis thaliana

description: Kondensine sind an der Kontraktion von Chromatin zur Bildung von Metaphase-Chromosomen beteiligt. In Hefen und Tieren wurde jedoch auch eine Beteiligung an der Interphasenchromatin- und Transkriptionsregulierung beschrieben. Die Kondensinkomplexe I und II sind auch in Arabidopsis vorhanden. In dieser Arbeit zeigen wir, dass die A. thaliana CAP-D2 (Kondensin I) und CAP-D3 (Kondensin II) -Untereinheiten in mitotisch aktiven Geweben stark exprimiert werden. Sie interagieren mit den anderen mutmaßlichen Untereinheiten der Kondensin I- oder II-Komplexe. Unsere Ergebnisse zeigen eine ähnliche Expression, Lokalisierung und Zusammensetzung der Kondensinkomplexe von A. thaliana wie in anderen höheren Eukaryoten. Frühere Experimente zeigten, dass die Reduktion von CAP-D3 während der Interphase zu einer Assoziation der Zentromer führt. Wir haben die Beteiligung von CAP-D3 an der Organisation und Transkription von Chromatin genauer analysiert. CAP-D3 verhindert die Assoziation heterochromatischer Sequenzen, beeinflusst jedoch nicht die Position der Chromozentren, die Kerngröße und die Methylierung. Wir schlagen ein Modell vor, bei dem CAP-D3 euchromatischen Schleifen versteift, und damit die Assoziation der Chromozentren verhindert.
description: Condensins are best known for their role shaping the chromosomes. However, other functions, as organization of interphase chromatin and transcriptional regulation, have been reported in yeasts and animals. The condensin complexes I and II are conserved in Arabidopsis thaliana. Here we show that the A. thaliana CAP-D2 (condensin I) and CAP-D3 (condensin II) subunits are highly expressed in mitotically active tissues. They interact with the other putative subunits of the condensin I or II complexes, respectively. Our research supports that the expression, localization and composition of the condensin complexes in A. thaliana are similar as in other higher eukaryotes. Previous experiments showed that the lack of CAP-D3 leads to centromere association during interphase. We analyzed in more detail the function of CAP-D3 in chromatin organization and transcription. CAP-D3 prevents the association of heterochromatic sequences but does not affect the chromocenter position at the inner nuclear membrane, as well as nuclear size and methylation. We propose a model in which CAP-D3 stiffens the euchromatic loops preventing the chromocenter association.

description: String-brane interactions provide an ideal framework to study the dynamics of the massive states of the string spectrum in a non-trivial background. We present here an analysis of tree-level amplitudes for processes in which an NS-NS string state from the leading Regge trajectory scatters from a D-brane into another state from the leading Regge trajectory, in general of a different mass, at high energies and small scattering angles. This is done by using world-sheet OPE methods and effective vertex operators. We find that this class of processes has a universal dependence on the energy of the projectile and that the tree-level amplitudes are in agreement with the eikonal operator form of the string S-matrix.

Towards Strict Sentence Intersection: Decoding and Evaluation Strategies

Publisher: name: Columbia University
Year: 2011
Subjects: Computer science

description: We examine the task of strict sentence intersection: a variant of sentence fusion in which the output must only contain the information present in all input sentences and nothing more. Our proposed approach involves alignment and generalization over the input sentences to produce a generation lattice; we then compare a standard search-based approach for decoding an intersection from this lattice to an integer linear program that preserves aligned content while minimizing the disﬂuency in interleaving text segments. In addition, we
introduce novel evaluation strategies for intersection problems that employ entailment-style judgments for determining the validity
of system-generated intersections. Our experiments show that the proposed models produce valid intersections a majority of the time and
that the segmented decoder yields advantages over the search-based approach.
Are passive red spirals truly passive? - The current star formation activity of optically-red disc galaxies

description: We use GALEX ultraviolet and WISE 22 micron observations to investigate the current star formation activity of the optically-red spirals recently identified as part of the Galaxy Zoo project. These galaxies were accurately selected from the Sloan Digital Sky Survey in order to be pure discs with low or no current star formation activity, representing one of the best optically-selected samples of candidate passive spirals. However, we show that these galaxies are not only still forming stars at a significant rate >= 1 M_sun/yr but, more importantly, their star formation activity is not different from that of normal star-forming discs of the same stellar mass (M* >= 10^10.2 M_sun). Indeed, these systems lie on the UV-optical blue sequence, even without any corrections for internal dust attenuation, and they follow the same specific star formation rate vs. stellar mass relation of star-forming galaxies. Our findings clearly show that, at high stellar masses, optical colours do not allow to discriminate between actively star-forming and truly quiescent systems.

description: Concept To Speech (CTS) systems are closely related to two other types of systems: Natural Language Generation (NLG) and Speech Synthesis (SS).

description: MHD waves can be responsible for plasma fluctuations and short-term variations of the pulsar emission. We consider the properties of plane and cylindrical waves that can exist in the force-free magnetosphere. Waves are considered by means of a linear analysis of the force-free MHD equations. We argue that these particular types of waves can exist in the magnetosphere of pulsars. These waves are closely related to the Alfven waves of the standard magnetohydrodynamics but are modified by the force-free condition and non-zero charge density. We derive the dispersion relation for magnetospheric waves and show that the wave periods are likely within the range $\sim 10^{-2}-10^(-4}$ s depending on the magnetospheric parameters.

description: We investigate whether wording, stylistic choices, and online behavior can be used to predict the age category of blog authors. Our hypothesis is that signiﬁcant changes in writing style distinguish pre-social media bloggers from post-social media bloggers. Through experimentation with a range of years, we found that the birth dates of students in college at the time when social media such as AIM, SMS text
messaging, MySpace and Facebook ﬁrst became popular, enable accurate age prediction. We also show that internet writing characteristics are important features for age prediction, but that lexical content is also needed to produce signiﬁcantly more accurate results. Our best results allow for 81.57% accuracy.

description: We study electron-spin-photon coupling in a single-spin double quantum dot embedded in a superconducting stripline cavity. With an external magnetic field, we show that either a spin-orbit interaction (for InAs) or an inhomogeneous magnetic field (for Si and GaAs) could produce a strong spin-photon coupling, with a coupling strength of the order of 1 MHz. With an isotopically purified Si double dot, which has a very long spin coherence time for the electron, it is possible to reach the strong-coupling limit between the spin and the cavity photon, as in cavity quantum electrodynamics. The coupling strength and relaxation rates are calculated based on parameters of existing devices, making this proposal experimentally feasible.

description: The Internet of Things (IoT) trend is introducing additional devices to home networks. Home networks face the same threats as every other network. Recently, IoT devices have been compromised by attackers and used as staging points for further attacks. Home users may not have the technical capability or funding to run advanced security devices designed to protect enterprises. Solutions to this problem exist, but in some cases, they rely on third party cloud services or require custom protocols to be deployed within the home network. Reliance on third party services comes with privacy implications, as well as the increased risk for a third party to be responsible for securing a network they may not directly control. Custom network protocols can effectively reduce the attack surface of home networks, but these are not easily compatible with devices in operation today. In this paper, we propose a new model for protecting home networks utilizing OpenFlow enabled Access Points (APs). The solution automatically builds least-permissive policies for each device and subsequently enforces the policies without requiring customized protocols. This allows the system to protect any connected wireless device. The design allows for a flexible deployment model and is capable of running on low cost hardware as an all-in-one unit. We perform a complete implementation and evaluation of the solution. The system can effectively limit the ability for compromised IoT devices to attack internal and external networks at a low cost to initial connection times.

description: This paper explores the automatic detection of sentences that are opinionated claims, in which the author expresses a belief. We use a machine learning based approach, investigating the impact of features such as sentiment and the output of a system that determines committed belief. We train and test our approach on social media, where people often try to convince others of the validity of their opinions. We experiment with two diﬀerent types of data, drawn from LiveJournal weblogs and Wikipedia discussion forums. Our experiments show that sentiment analysis is more important in LiveJournal, while committed
belief is more helpful for Wikipedia. In both corpora,n-grams and part-of-speech features also account for signiﬁcantly better accuracy. We discuss the ramiﬁcations behind these diﬀerences.

description: Automatic post-editors (APEs) enable the re-use of black box machine translation (MT) systems for a variety of tasks where different aspects of translation are important. In this paper, we describe APEs that target adequacy errors, a critical problem for tasks such as cross-lingual question-answering, and compare different approaches for post-editing: a rule-based system and a feedback approach that uses a computer in the loop to suggest improvements to the MT system. We test the APEs on two different MT systems and across two different genres. Human evaluation shows that the APEs signiﬁcantly improve adequacy, regardless of approach, MT system or genre: 30-56% of the post-edited sentences have improved adequacy compared to the original MT.

description: Dark matter sub-halos create gaps in the stellar streams orbiting in the halos of galaxies. We evaluate the sub-halo stream crossing integral with the guidance of simulations to find that the linear rate of gap creation, R_gap, in a typical Cold Dark Matter (CDM) galactic halo at 100 kpc is R_gap = 0.0066 M_8^-0.35 kpc^-1 Gyr^-1$, where M_8 = M/10^8 M_sun, is the minimum mass halo that creates a visible gap. The relation can be recast entirely in terms of observables, as R_gap= 0.059 w^-0.85 kpc^-1 Gyr^-1, for w in kpc, normalized at 100 kpc. Using published data, the density of gaps is estimated for M31's NW stream and the Milky Way Pal 5 stream, Orphan stream, and Eastern Banded Structure. The estimated rates of gap creation all have errors of 50% or more due to uncertain dynamical ages and the relatively noisy stream density measurements. The gap rate-width data are in good agreement with the CDM predicted relation. The high density of gaps in the narrow streams require a total halo population of 10^5 sub-halos above a minimum mass of 10^5 M_sun.

description: We investigate the dynamics of pairs of drops in microfluidic ladder networks with slanted bypasses, which break the fore-aft structural symmetry. Our analytical results indicate that unlike symmetric ladder networks, structural asymmetry introduced by a single slanted bypass can be used to modulate the relative drop spacing, enabling them to contract, synchronize, expand, or even flip at the ladder exit. Our experiments confirm all these behaviors predicted by theory. Numerical analysis further shows that while ladder networks containing several identical bypasses are limited to nearly linear transformation of input delay between drops, mixed combination of bypasses can cause significant non-linear transformation enabling coding and decoding of input delays.

description: We present DefScriber, a fully implemented system that combines knowledge-based and statistical methods in forming multi-sentence answers to open-ended definitional questions of the form, "What is X?" We show how a set of definitional predicates proposed as the knowledge-based side of our approach can be used to guide the selection of definitional sentences. Finally, we present results of an evaluation of definitions generated by DefScriber from Internet documents.

description: We report on two corpora to be used in the evaluation of component systems for the tasks of (1) linear segmentation of text and (2) summary-directed sentence extraction. We present characteristics of the corpora, methods used in the collection of user judgments, and an overview of the application of the corpora to evaluating the component system. Finally, we discuss the problems and issues with construction of the test set which apply broadly to the construction of evaluation resources for language technologies.

Spoken language generation in a multimedia system

description: In this paper we addresses two important issues in generating spoken language within a multimedia system: the design of a speech generator to facilitate coordination between media, and extensions to the functionality of a written-language generation system to produce natural speech output. We demonstrate how a speech generator can produce information that allows for temporal coordination between multiple media. We describe how our speech generator takes advantage of rich and accurate syntactic and semantic information during text planning and speech realization. This enables the system to accurately predict, generate and utilize prosodic features to facilitate the coordination of speech with graphical actions such as highlighting.

description: We present a new method for discovering a segmental discourse structure of a document while categorizing each segment's function and importance. Segments are determined by a zero-sum weighting scheme, used on occurrences of noun phrases and pronominal forms retrieved from the document. Segment roles are then calculated from the distribution of the terms in the segment. Finally, we present results of evaluation in terms of precision and recall which surpass earlier approaches.
Quantitative Research Methods Training in Education Leadership and Administration Preparation Programs as Disciplined Inquiry for Building School Improvement Capacity

Educational leadership

description: The quantitative research methods course is a staple of graduate programs in education leadership and administration. Historically, these courses serve to train aspiring district and school leaders in fundamental statistical research topics. This article argues for programs to focus as well in these courses on helping aspiring leaders develop skills as practitioner-scholars, including deepening their practice around data analytics, providing opportunities to read and evaluate peer-reviewed research, analyzing data using current methods, and applying findings to facilitate building evidence-based improvement cycles in their schools. Additional data leadership training should be offered for the practicing administrator, educational quantitative analyst, research specialist and district data scientist.

description: Why engage with ESKD in central Texas? Our adult kidney transplant program opened at the University of Texas at Austin and Dell Seton Medical Center in November 2021 with the goal of delivering equitable, world-class, and evidence-based care to all people of central Texas. As we grow and learn how to best serve our community, our abdominal transplant program at the University of Texas at Austin is uniquely positioned to study, address, and counteract local disparities via patient-centered research. Core questions: To identify innovative, patient-centered solutions that advance equity, we used our IC2 funding to launch a parallel mixed-methods study to ask the following core questions about ESKD in central Texas: What are the social determinants of health that most strongly impact access to primary, nephrology, andtransplant care? What are the barriers and facilitators of being referred and evaluated for kidney transplantation? How and to what extent can we better identify and serve patients of an underserved or marginalizedcommunity that would benefit from transplantation services? What does equity in access to transplantation mean to patients with ESKD and their caregivers?
Persistent currents in a graphene ring with armchair edges

description: A graphene nano-ribbon with armchair edges is known to have no edge state. However, if the nano-ribbon is in the quantum spin Hall (QSH) state, then there must be helical edge states. By folding a graphene ribbon to a ring and threading it by a magnetic flux, we study the persistent charge and spin currents in the tight-binding limit. It is found that, for a broad ribbon, the edge spin current approaches a finite value independent of the radius of the ring. For a narrow ribbon, inter-edge coupling between the edge states could open the Dirac gap and reduce the overall persistent currents. Furthermore, by enhancing the Rashba coupling, we find that the persistent spin current gradually reduces to zero at a critical value, beyond which the graphene is no longer a QSH insulator.
