description: Web pages often contain clutter (such as ads, unnecessary images and extraneous links) around the body of an article, which distracts a user from actual content. Automatic extraction of 'useful and relevant' content from web pages has many applications, including browsing on small cell phone and PDA screens, speech rendering for the visually impaired, and reducing noise for information retrieval systems. Prior work has led to the development of Crunch, a framework which employs various heuristics in the form of filters and filter settings for content extraction. Crunch allows users to tune these settings, essentially the thresholds for applying each filter. However, in order to reduce human involvement in selecting these heuristic settings, we have extended this work to utilize a website's classification, defined by its genre and physical layout. In particular, Crunch would then obtain the settings for a previously unknown website by automatically classifying it as sufficiently similar to a cluster of known websites with previously adjusted settings - which in practice produces better content extraction results than a single one-size-fits-all set of setting defaults. In this paper, we present our approach to clustering a large corpus of websites by their genre, utilizing the snippets generated by sending the website's domain name to search engines as well as the website's own text. We find that exploiting these snippets not only increased the frequency of function words that directly assist in detecting the genre of a website, but also allow for easier clustering of websites. We use existing techniques like Manhattan distance measure and Hierarchical clustering, with some modifications, to pre-classify websites into genres. Our clustering method does not require prior knowledge of the set of genres that websites fit into, but instead discovers these relationships among websites. Subsequently, we are able to classify newly encountered websites in linear-time, and then apply the corresponding filter settings, with no noticeable delay introduced for the content-extracting web proxy.
Quantifying mortality risk in small defined-benefit pension schemes
Creators: name: Donnelly, Catherine

Subjects: subject: Risk Management (q-fin.RM)

description: A risk of small defined-benefit pension schemes is that there are too few members to eliminate idiosyncratic mortality risk, that is there are too few members to effectively pool mortality risk. This means that when there are few members in the scheme, there is an increased risk of the liability value deviating significantly from the expected liability value, as compared to a large scheme. We quantify this risk through examining the coefficient of variation of a scheme's liability value relative to its expected value. We examine how the coefficient of variation varies with the number of members and find that, even with a few hundred members in the scheme, idiosyncratic mortality risk may still be significant. Using a stochastic mortality model reduces the idiosyncratic mortality risk but at the cost of increasing the overall mortality risk in the scheme. Next we quantify the amount of the mortality risk concentrated in the executive section of the scheme, where the executives receive a benefit that is higher than the non-executive benefit. We use the Euler capital allocation principle to allocate the total standard deviation of the liability value between the executive and non-executive sections. We find that the proportion of the standard deviation allocated to the executive section is higher than is suggested by an allocation based on the members' benefit amounts. While the results are sensitive to the choice of mortality model, they do suggest that the mortality risk of the scheme should be monitored and managed within the sections of a scheme, and not only on a scheme-wide basis.

description: For a fixed initial reference measure, we study the dependence of the escape rate on the hole for a smooth or piecewise smooth hyperbolic map. First, we prove the existence and Holder continuity of the escape rate for systems with small holes admitting Young towers. Then we consider general holes for Anosov diffeomorphisms, without size or Markovian restrictions. We prove bounds on the upper and lower escape rates using the notion of pressure on the survivor set and show that a variational principle holds under generic conditions. However, we also show that the escape rate function forms a devil's staircase with jumps along sequences of regular holes and present examples to elucidate some of the difficulties involved in formulating a general theory.

description: the administrative control of the Nāik Pratāp Rāu Sardesāi family extended over most of the present central and south Goa, “and for considerable periods of time beyond the mountains over the region of Belgaum and Dharwar.” What is meant by ‘central and south Goa’ here is the territory to the south and to the east of the Tisvāḍi mahāl. Tisvāḍi mahāl was not a part of any watandārī, being administered directly by the king, as it was a port region. As for the antiquity of this watandārī, we can safely assume that it prevailed during the Bijapuri rule and during the Vijayanagar rule before that, as we shall soon see. But, if we are to go by Vaman Narhar Sardesai’s Mavalankar Gharanyacha Itihas, the family title of sardesāi as such can be traced to theŚilāhār times. Does the history of this sardesāi too go back to the Śilāhār times ?

description: Background: Colorectal cancer (CRC) is one of the most prevalent cancer types worldwide. Despite the advancements in current diagnosis and treatment strategies of CRC, the incidence and mortality rates of CRC have been rising. To explore novel mechanism of CRC, this study focused on the expression pattern and functional mechanism of murine retrovirus integration site 1 (MRVI1) in CRC. Methods: Tumor tissues and adjacent normal tissues were collected from CRC patients, and the expression levels of MRVI1 were determined by RT-PCR and Western blot. MRVI1 knockdown was achieved by shRNA in HCT116 and HT29 cells, followed by CCK-8 assay to detect the cell proliferation, and caspase-3 activity assay combined with nucleosome ELISA assay to detect cell apoptosis. Transwell assay was used to detect cell invasion and luciferase reporter assay was used to validate the activation of the MRVI1 promoter by p53. Results: MRVI1 was downregulated in CRC tissues and several CRC cell lines. Knockdown of MRVI1 enhanced the proliferation and apoptosis, while promoted invasion and stemness of CRC cells. Mechanism study revealed that MRVI1 was transcriptionally activated by p53 at its upstream. In addition, p53-induced inhibition of CRC prognosis depended on MRVI1. Conclusion: MRVI1 inhibited the prognosis of CRC via a mechanism involving p53 activation. MRVI1 could serve as a potential target for clinical diagnosis and treatment of CRC.
Next-to-leading-order corrections to $B \to π$ form factors in $k_T$ factorization

description: We calculate next-to-leading-order (NLO) corrections to the $B\toπ$ transition form factors at leading twist in the $k_T$ factorization theorem. Light partons off-shell by $k_T^2$ are considered in the quark diagrams, in the effective diagrams for the $B$ meson wave function defined with the effective heavy-quark field, and in the effective diagrams for the pion wave function. It is explicitly demonstrated that the infrared logarithms $\ln k_T^2$ cancel between the above sets of diagrams, as deriving the $k_T$-dependent NLO hard kernel from their difference. The infrared finiteness of the hard kernel confirms the application of the $k_T$ factorization theorem to $B$ meson semileptonic decays. The NLO pion wave function is identical to those constructed from the pion transition and electromagnetic form factors, consistent with its universality. Choosing the renormalization and factorization scales lower than the $B$ meson mass, the NLO corrections are under control: they amount only up to 30% of the form factors at large recoil of the pion, when varying models for the meson wave functions.

Manipulating Managed Execution Runtimes to Support Self-Healing Systems
Creators: name: Griffith, Rean
name: Kaiser, Gail E.
Publisher: name: Columbia University
Year: 2005
Subjects: Computer science

description: Self-healing systems require that repair mechanisms are available to resolve problems that arise while the system executes. Managed execution environments such as the Common Language Runtime (CLR) and Java Virtual Machine (JVM) provide a number of application services (application isolation, security sandboxing, garbage collection and structured exception handling) which are geared primarily at making managed applications more robust. However, none of these services directly enables applications to perform repairs or consistency checks of their components. From a design and implementation standpoint, the preferred way to enable repair in a self-healing system is to use an externalized repair/adaptation architecture rather than hardwiring adaptation logic inside the system where it is harder to analyze, reuse and extend. We present a framework that allows a repair engine to dynamically attach and detach to/from a managed application while it executes essentially adding repair mechanisms as another application service provided in the execution environment.

Semiclassical approximations for adiabatic slow-fast systems

description: In this letter we give a systematic derivation and justification of the semiclassical model for the slow degrees of freedom in adiabatic slow-fast systems first found by Littlejohn and Flynn [5]. The classical Hamiltonian obtains a correction due to the variation of the adiabatic subspaces and the symplectic form is modified by the curvature of the Berry connection. We show that this classical system can be used to approximate quantum mechanical expectations and the time-evolution of operators also in sub-leading order in the combined adiabatic and semiclassical limit. In solid state physics the corresponding semiclassical description of Bloch electrons has led to substantial progress during the recent years, see [1]. Here, as an illustration, we show how to compute the Piezo-current arising from a slow deformation of a crystal in the presence of a constant magnetic field.

description: The Synthesis distributed operating system combines efficient kernel calls with a high-level, orthogonal interface. The key concept is the use of a code synthesizer in the kernel to generate specialized (thus short and fast) kernel routines for specific situations. We have three methods of synthesizing code: Factoring Invariants to bypass redundant computations; Collapsing Layers to eliminate unnecessary procedure calls and context switches; and Executable Data Structures to shorten data structure traversal time. Applying these methods, the kernel call synthesized to read /dev/mem takes about 15 microseconds on a 68020 machine. A simple model of computation called a synthetic machine supports parallel and distributed processing. The interface to synthetic machine consists of six operations on four kinds of objects. This combination of a high-level interface with the code synthesizer avoids the traditional trade-off in operating systems between powerful interfaces and efficient implementations.

description: Large datasets, of the order of peta- and tera- bytes, are becoming prevalent in many scientific domains including astronomy, physical sciences, bioinformatics and medicine. To effectively store, query and analyze these gigantic repositories, parallel and distributed architectures have become popular. Apache Hadoop is one such framework for supporting data-intensive applications. It provides an open source implementation of the MapReduce programming paradigm which can be used to build scalable algorithms for pattern analysis and data mining. In this paper, we present a PArallel, RAndom-partition Based hierarchical clustEring algorithm (PARABLE) for the MapReduce framework. It proceeds in two main steps -- local hierarchical clustering on nodes using mappers and reducers and integration of results by a novel dendrogram alignment technique. Empirical results on two large data sets (High Energy Particle Physics and Intrusion Detection) from the KDDCup competition on a large cluster indicates that significant scalability benefits can be obtained by using the parallel hierarchical clustering algorithm in addition to maintaining good cluster quality.
Les visages du grotesque dans le theatre de Matei Visniec

A l 'heure actuelle, les pieces visnieciennes continuent de susciter des reponses, des opinions et des interpretations variees et melangees de la part des spectateurs amateurs ou professionnels, ces demiers hesitant souvent a les circonscrire a un genre ou a une categorie precise et unique. A la verite, Matei Visniec s'est affirme par son habilete de mettre au profit les conquetes du theatre absurde, grotesque, onirique, fantastique, etc. appartenant a l'espace litteraire et culturel roumain, russe, sud-europeen, occidental, etc. A cote de la veine lyrique 1' auteur manifeste un penchant pour le mode grotesque, un mode d' ecriture paradoxal avec des racines dans les arts decoratifs antiques et puis renaissants, ce qui pose la question de la visibilite et du pictural dans son theatre. Pour le propos de ce travail, nous avons pris en compte plusieurs perspectives critiques convergentes, complementaires ou bien divergentes, aptes a donner une image d'ensemble, mais aussi plus raffinee et detaillee, done complexe, sur le phenomene grotesque, avec ses multiples facettes qui demeurent parfois cachees. Des pieces formant le corpus de ce travail, la premiere se prete a une interpretation effectivement grotesque, tandis que la deuxieme accorde une liberte plus grande quand a la maniere de son approche critique et scenique. Par contre, toutes les deux illustrent la versatilite et le potentiel du grotesque de changer ses visages et ses fonctions, selon les intentions de l' auteur, mais aussi selon le contexte ou le cadre socioculturel ou une pareille reuvre dramatique nait et evolue.

description: We propose a new, generic mechanism of inflation mediated by a balance between potential forces and a Chern-Simons interaction. Such quasi-topological interactions are ubiquitous in string theory. In the minisuperspace approximation, their effect on the dynamics can be mapped onto the problem of a charged particle in an electromagnetic field together with an external potential; slow roll arises when the motion is dominated by the analogue of `magnetic drift'. This mechanism is robust against radiative corrections. We suggest a possible experimental signature which, if observed, might be considered strong evidence for string theory.

description: Content delivery networks play a crucial role in today's Internet. They serve a large portion of the multimedia on the Internet and solve problems of scalability and indirectly network congestion (at a price). However, most content delivery networks rely on a statically deployed configuration of nodes and network topology that makes it hard to grow and scale dynamically. We present ActiveCDN, a novel CDN architecture that allows a content publisher to dynamically scale their content delivery services using network virtualization and cloud computing techniques.

Countering Network Worms Through Automatic Patch Generation

description: The ability of worms to spread at rates that effectively preclude human-directed reaction has elevated them to a first-class security threat to distributed systems. We propose an architecture for automatically repairing software flaws that are exploited by zero-day worms.Our approach relies on source code transformations to quickly apply automatically-created (and tested) localized patches to vulnerable segments of the targeted application. To determine these susceptible portions, we use a sandboxed instance of the application as a "clean room" laboratory that runs in parallel with the production system and exploit the fact that a worm must reveal its infection vector to achieve its goal (i.e., further infection). We believe our approach to be the first end-point solution to the problem of malicious self-replicating code. The primary benefits of our approach are (a) its low impact on application performance, (b) its ability to respond to attacks without human intervention, and (c) its capacity to deal with zero-day worms (for which no known patches exist). Furthermore, our approach does not depend on a centralized update repository, which can be the target of a concerted attack similar to the Blaster worm. Finally, our approach can also be used to protect against lower intensity attacks, such as intrusion ("hack-in") attempts. To experimentally evaluate the efficacy of our approach, we use our prototype implementation to test a number of applications with known vulnerabilities. Our preliminary results indicate a success rate of 82\%, and a maximum repair time of 8.5 seconds.

description: The Gene Expression Database (GXD), an extensive community resource of curated expression information for the mouse, has developed an RNA-Seq and Microarray Experiment Search (http://www.informatics.jax.org/gxd/htexp_index). This tool allows users to quickly and reliably find specific experiments in ArrayExpress and the Gene Expression Omnibus (GEO) that study endogenous gene expression in wild-type and mutant mice. Standardized metadata annotations, curated by GXD, allow users to specify the anatomical structure, developmental stage, mutated gene, strain and sex of samples of interest, as well as the study type and key parameters of the experiment. These searches, powered by controlled vocabularies and ontologies, can be combined with free text searching of experiment titles and descriptions. Search result summaries include link outs to ArrayExpress and GEO, providing easy access to the expression data itself. In addition we have recently expanded GXD to include RNA Seq data. Uniformly processed RNA Seq data are imported from the EBI Expression Atlas and then integrated with the other types of expression data in GXD, and with the genetic, functional, phenotypic and disease-related information in Mouse Genome Informatics (MGI). This integration has made the RNA Seq data accessible via GXD's enhanced searching and filtering capabilities. Further, we have embedded the Morpheus heat map utility into the GXD user interface to provide additional tools for display and analysis of RNA Seq data, including heat map visualization, sorting, filtering, hierarchical clustering, nearest neighbors analysis and visual enrichment. More information can be found at the GXD home page (http://www.informatics.jax.org/expression.shtml).

description: Obtaining ideal gene delivery vectors is still a major goal in cancer gene therapy. CAMEL, a short hybrid antimicrobial peptide, can kill cancer cells by membrane lysis. In this study, we constructed a series of non-viral vectors by attaching fatty acids with different chain lengths to the N-terminus of CAMEL. Our results showed that the cellular uptake and transfection efficiency of acyl-CAMEL started to significantly increase from a chain length of 12 carbons. C18-CAMEL was screened for gene delivery because it had the highest transfection efficiency. Surprisingly, C18-CAMEL/plasmid complexes displayed strong endosomal escape activity after entering cells via endocytosis. Importantly, C18-CAMEL could deliver p53 plasmids to cancer cells and significantly inhibited cell proliferation by the expression of p53. In addition, the C18-CAMEL/p53 plasmid complexes and the MDM2 inhibitor nutlin-3a showed significantly synergistic anticancer activity against MCF-7 cells expressing wild-type p53. Conclusively, our study demonstrated that conjugation of stearic acid to antimicrobial peptides is a simple and successful approach for constructing efficient and economical non-viral vectors for cancer gene therapy.

description: Composite bosons, here called {\it quasibosons} (e.g. mesons, excitons, etc.), occur in various physical situations. Quasibosons differ from bosons or fermions as their creation and annihilation operators obey non-standard commutation relations, even for the "fermion+fermion" composites. Our aim is to realize the operator algebra of quasibosons composed of two fermions or two q-fermions (q-deformed fermions) by the respective operators of deformed oscillators, the widely studied objects. For this, the restrictions on quasiboson creation/annihilation operators and on the deformed oscillator (deformed boson) algebra are obtained. Their resolving proves uniqueness of the family of deformations and gives explicitly the deformation structure function (DSF) which provides the desired realization. In case of two fermions as constituents, such realization is achieved when the DSF is quadratic polynomial in the number operator. In the case of two q-fermions, q\neq 1, the obtained DSF inherits the parameter q and does not continuously converge when q\to 1 to the DSF of the first case.

description: We present an Edit-and-Continue implementation that allows regular source files to be treated like interactively updatable, compiled scripts, coupling the speed of compiled native machine code, with the ability to make changes without restarting. Our implementa-tion is based on the Microsoft .NET Framework and allows applications written in any .NET language to be dynamically updatable. Our solution works with the standard version of the Microsoft Common Language Runtime, and does not require a custom compiler or runtime. Because no application changes are needed, it is transparent to the application developer. The runtime overhead of our implementation is low enough to support updating real-time applications (e.g., interactive 3D graphics applications).
Transgressing words and silence : aesthetics, ethics and education
Creators: name: MacLeod, Kathryn Dawn
Publisher: name: University of British Columbia
Year: 2011

description: This thesis explores the relationship between ethics, aesthetics and education, using the limit case of art created in response to the Holocaust, and argues that art is not autonomous: The theme of the Holocaust speaks directly to the question of art’s relationship to moral, political and educational purpose. Guided by the philosophy of Maxine Greene, Jean-Francois Lyotard, and Immanuel Kant, this thesis focuses on three works by artists who have addressed the Holocaust in their work: writer Primo Levi, filmmaker Claude Lanzmann, and sculptor Rachel Whiteread. Lyotard’s aesthetic and political theories, based on his reading of Kant’s Critique of the Power of Judgment, link the practice of contemporary art to a postmodern ethics; his key concepts of the différend, the event and the sublime provide a basis for my analysis of how the each of these artworks works. Art that attempts to explore the aporia of the Holocaust faces specific issues: the role of beauty and redemption; the relationship between art and the real; the impact of trauma on memory and representation; and the nature of testimony. Each of the artworks addresses these challenges: Whiteread’s sculpture explores the reality and materiality of absence; Lyotard’s film reveals the traces and gaps in memory and history; and Levi’s memoir highlights the power and frailty of art and communication. Understanding the nature of contemporary art provides insight into art’s value and purpose. Art’s ethical obligation lies in its relationship to the real: If art can address the aporia of the Holocaust, then it is valuable, necessary and important in our culture. Art creates new ways of seeing and responding to the world, and has the ability to transform. At the same time, art’s distance from the real always limits its efficacy. Art educates not merely through formal means uncovered in the classroom, but because it engages its audience in reflective judgment, in making meaning while at the same time questioning the ability to do so.
Parallel Probing of Web Databases for Top-k Query Processing

description: A top-k query specifies a set of preferred values for the attributes of a relation and expects as a result the k objects that are closest to the given preferences according to some distance function. In many web applications, the relation attributes are only available via probes to autonomous web-accessible sources. Probing these sources sequentially to process a top-k query is inefficient, since web accesses exhibit high and variable latency. Fortunately, web sources can be probed in parallel, and each source can typically process concurrent requests, although sources may impose some restrictions on the type and number of probes that they are willing to accept. These characteristics of web sources motivate the introduction of parallel top-k query processing strategies, which are the focus of this paper. We present efficient techniques that maximize source-access parallelism to minimize query response time, while satisfying source access constraints. A thorough experimental evaluation over both synthetic and real web sources shows that our techniques can be significantly more efficient than previously proposed sequential strategies. In addition, we adapt our parallel algorithms for the alternate optimization goal of minimizing source load while still exploiting source-access parallelism.

description: A problem is said to be ill-posed if the solution of the problem does not depend continuously on the input data. In this survey paper, we consider two different information-based settings for the optimal computation of approximate solution of ill-posed linear problems, namely the worst case and average case settings. These settings are studied for two different error criteria, namely, the absolute error and the residual error criteria. The main result for the absolute-error criterion is that algorithms having finite error exist for a given setting if and only if the solution operator is bounded in that setting. In the worst case setting with an absolute error criterion, this means that there is no algorithm for solving ill-posed problems having finite error. In the average case setting with an absolute error criterion, this means that algorithms having finite error exist if and only if the solution operator is "bounded on the average." Furthermore, when this holds, we exhibit optimal information of cardinality n, finding that the nth minimal average error goes to zero as n → ∞. The main result for the residual error criterion is that the problem may be formally reduced to the approximation problem. Hence, finite-error algorithms always exist. We exhibit optimal information of cardinality n. In the worst case setting, we give a necessary and sufficient condition for the nth minimal error to go to zero as n → ∞; in the average case setting, this always occurs. We use these results to determine the ε-complexity of ill-posed problems. The ε-complexity is infinite for anyε > 0 in the worst case setting with the absolute criterion. However, in the average case setting with either error criterion and the worst case setting with the residual error criterion, we determine necessary and sufficient conditions for the ε-complexity to be finite for all ε > 0; moreover, we find algorithms yielding ε-approximations with almost-minimal cost.

description: The purpose of this qualitative case study was to gain a deeper understanding of the effectiveness of instructional leadership practices of learning leaders that support teacher instruction and potentially student learning in middle school settings. I conducted a case study that included four urban public middle schools (Grades 4 to 9) and explored the perspectives of four principals, four teachers, and four learning leaders. This study was guided by three main research questions: (a) What learning leader practices are perceived by principals, learning leaders, and teachers to be effective in supporting student learning? (b) What learning leader practices are perceived by principals, learning leaders, and teachers to be effective at improving teacher practice? (c) How are principals’, teachers’, and learning leaders’ perspectives similar or different? A critical review of the literature has demonstrated that learning leaders can play a vital role in school leadership by supporting teaching practices and student learning in schools. I conducted 20 semistructured interviews with the participants. The data was coded and organized into themes. Based on the data analysis, the findings from research questions one and two revealed that the participants perceived that school leaders need to implement certain physical and organizational structures to effectively support teacher practice and student learning. However, the findings did indicate that structures alone will not adequately support teacher practice and student learning. The findings show that learning leaders established trusting relationships with teachers allowing them to promote a collaborative school culture and develop teacher’s instructional capacity. The results of this research suggest that effective learning leaders were those who possessed the skills, knowledge, and characteristics that encouraged effective teaching and learning. The findings from research question three revealed that principals, teachers, and learning leaders held similar perceptions about leadership practices that support teacher practice and student learning. A conclusion drawn was that creating a school culture focused on collaborative instructional leadership has a positive impact on student learning and teacher practice.

description: Reservoir computing is a recently introduced, highly efficient bio-inspired approach for processing time dependent data. The basic scheme of reservoir computing consists of a non linear recurrent dynamical system coupled to a single input layer and a single output layer. Within these constraints many implementations are possible. Here we report an opto-electronic implementation of reservoir computing based on a recently proposed architecture consisting of a single non linear node and a delay line. Our implementation is sufficiently fast for real time information processing. We illustrate its performance on tasks of practical importance such as nonlinear channel equalization and speech recognition, and obtain results comparable to state of the art digital implementations.

description: A simple and mild protocol for the palladium-catalyzed Suzuki reaction of aryl bromides and arylboronic acids is developed. The cross-coupling reactions can be performed at room temperature using 5.0 equiv. of Et3N as solvent and base without any ligands, and affording biaryl products in good yields. In addition, the chemoselecitive Suzuki reaction of bromo-N-methyliminodiacetic acid (MIDA) boronates with arylboronic acids can be achieved in this system, and various unsymmetrical terphenyls have been prepared in moderate yields by one-pot double Suzuki reactions.
802.11b Throughput with Link Interference

description: IEEE 802.11 MAC is a CSMA/CA protocol and uses RTS/CTS exchanges to avoid the hidden terminal problem. Recent findings have revealed that the carriersensing range set in current major implementations does not detect and prevent all interference signals even using RTS/CTS access method together. In this paper, we investigate the effect of interference and develop a mathematical model for it. We demonstrate that the 802.11 DCF does not properly act on the interference channel due to the small size and the exponential increment of backoff windows. The accuracy of our model is verified via simulations. Based on an insight from our model, we present a simple protocol that operates on the top of 802.11 MAC layer and achieves more throughput than rate-adjustment schemes.

description: We discuss the elastic versions of block ciphers whose round function processes subsets of bits from the data block differently, such as occurs in a Feistel network and in MISTY1. We focus on how specific bits are selected to be swapped after each round when forming the elastic version, using an elastic version of MISTY1 and differential cryptanalysis to illustrate why this swap step must be carefully designed. We also discuss the benefit of adding initial and final key dependent permutations in all elastic block ciphers. The implementation of the elastic version of MISTY1 is analyzed from a performance perspective.

description: Electronic structure calculations of the Verwey ground state of magnetite, Fe3O4, using density functional theory with treatment of on-site Coulomb interactions (DFT+U scheme) are reported. These calculations use the recently-published experimental crystal structure coordinates for magnetite in the monoclinic space group Cc. The computed density distribution for minority spin electron states close to the Fermi level demonstrates that charge order and Fe2+-orbital order are present at the B-type lattice sites to a first-approximation. However, Fe2+/Fe3+ charge differences are diminished through weak bonding interactions of the Fe2+-states to specific pairs of neighboring iron sites that create linear, three-B-atom trimeron units that may be regarded as 'orbital molecules'. Trimerons are ordered evenly along most Fe atom chains in the Verwey structure, but more complex interactions are observed within one chain.

description: We consider orthogonal connections with arbitrary torsion on compact Riemannian manifolds. For the induced Dirac operators, twisted Dirac operators and Dirac operators of Chamseddine-Connes type we compute the spectral action. In addition to the Einstein-Hilbert action and the bosonic part of the Standard Model Lagrangian we find the Holst term from Loop Quantum Gravity, a coupling of the Holst term to the scalar curvature and a prediction for the value of the Barbero-Immirzi parameter.
