description: Following our discovery of radio pulsations from the newly recognized Anomalous X-ray Pulsar (AXP) 1E 1547.0-5408, we initiated X-ray monitoring with the Swift X-ray Telescope, and obtained a single target-of-opportunity observation with the Newton X-ray Multi-Mirror Mission (XMM-Newton). In comparison with its historic minimum flux of 3e-13 ergs cm^-2 s^-1, the source was found to be in a record high state, f_X(1-8 keV) = 5e-12 ergs cm^-2 s^-1, or L_X = 1.7e35(d/9 kpc)^2 ergs s^-1, and declining by 25% in 1 month. Extrapolating the decay, we bound the total energy in this outburst to 1e42 < E < 1e43 ergs. The spectra (fitted with a Comptonized blackbody) show that an increase in the temperature and area of a hot region, to 0.5 keV and ~16% of the surface area of the neutron star, respectively, are primarily responsible for its increase in luminosity. The energy, spectrum, and timescale of decay are consistent with a deep crustal heating event, similar to an interpretation of the X-ray turn-on of the transient AXP XTE J1810-197. Simultaneous with the 4.6 hour XMM-Newton observation, we observed at 6.4 GHz with the Parkes telescope, measuring the phase relationship of the radio and X-ray pulse. The X-ray pulsed fraction of 1E 1547.0-5408 is only ~7%, while its radio pulse is relatively broad for such a slow pulsar, which may indicate a nearly aligned rotator. As also inferred from the transient behavior of XTE J1810-197, the only other AXP known to emit in the radio, the magnetic field rearrangement responsible for this X-ray outburst of 1E 1547.0-5408 is probably the cause of its radio turn-on.

description: MSR is an unambiguous, flexible, powerful and relatively simple specification framework for crypto-protocols. It uses multiset rewriting rules over first-order atomic formulas to express protocol actions and relies on a form of existential quantification to symbolically model the generation of nonces and other fresh data. It supports an array of useful static checks that include type-checking and data access verification. In this paper, we give a detailed presentation of the typing infrastructure of MSR, which is based on the theory of dependent types with subsorting. We prove that type-checking protocol specifications is decidable and show that execution preserves well-typing. We illustrate these features by formalizing a well-known protocol in MSR
LE MOUVEMENT DES TOURNESOLS COMME RÉVÉLATEUR DE L’IDÉAL DÉMOCRATIQUE DES JEUNES TAÏWANAIS

description: Les tensions entourant les questions démocratiques et l’intégration économique de Taïwan au sein de la Chine continentale sont présentes depuis des décennies. En 2008, après la victoire du président taïwanais Ma Ying-Jeou, du parti KMT, celui-ci a renforcé le partenariat économique avec la Chine afin de réduire les barrières commerciales entre Taïwan et la Chine. Lors du renouvellement de cet accord, en 2014, un mouvement social composé d’étudiants taïwanais, dénommé le mouvement des tournesols s’y opposa. Selon ces acteurs sociaux, cet accord économique entre la Chine et Taïwan affecterait la souveraineté, la démocratie de Taïwan et celle-ci risquerait d’être pleinement intégrée à la Chine continentale. Le mouvement des tournesols ne dura que de vingt-quatre jours. Cependant, il est devenu la mobilisation pro-démocratie la plus importante de l’histoire de l’île de Taïwan. En effet, les valeurs démocratiques et l’identité nationale étaient au cœur des revendications des jeunes Taïwanais. Les jeunes ont non seulement réussi à s’imposer face aux autorités politiques, mais le mouvement des tournesols a eu un effet transformatif au sein toute la société civile et politique taïwanaise comme jamais auparavant. L’analyse débutera par un portrait historique des mouvements sociaux et de la construction identitaire à Taïwan. Elle se poursuivra par une analyse du mouvement des tournesols en combinant deux théories celle de l’opportunité politique et celle des nouveaux mouvements sociaux. Nous démonterons à l’aide d’une analyse de sources secondaires comment les impacts du mouvement des tournesols ont transcendé la société taïwanaise dans les sphères politiques, économiques, démocratiques, sociales, culturelles et identitaires. Finalement, en s’opposant à l’accord de libre-échange, les jeunes Taïwanais ont pu réaffirmer leur identité dont le cœur même se nourrit des valeurs démocratiques.

description: We investigate experimentally the local erosion of a granular bed near a fixed vertical cylinder that emerges from the bed. The onset of erosion arising at the base of the cylinder and usually ascribed to the wrapping horseshoe vortex is determined and rationalized by a flow contraction effect. We report a new erosion pattern visible downstream of the cylinder that consists of two side-by-side elongated holes. This pattern is observed for flow regimes close to the horseshoe scour onset, whose growth usually inhibits its spatiotemporal development.

ENRICHED HIGH—TITER anti-HEPATITIS A VIRUS (HAV) IgM FOR POSITIVE CONTROLS IN DIAGNOSTIC DEVICES
Creators: name: Patamawenu, Terry
Publisher: name: Maryland Shared Open Access Repository
Year: 2010

description: Hepatitis A refers to liver inflammation caused by infection with the hepatitis A virus (HAV). The HAV is one of several viruses that can cause hepatitis and is one of the 3 most common hepatitis viruses in the United States. The other 2 are hepatitis B and hepatitis C viruses. The presence of anti-HAV IgM in serum indicates the acute or early convalescent stage of HAV infection. Although several commercial tests are available to aid in diagnosis, the lack of available high titer plasma for positive control, due to the short window of the IgM response following infection (5-10 weeks after exposure) and the low U.S. incidence of the HAV (one in 20,000 or 5 cases per 100,000) is a persistent problem. Samples collected prior to 4 and later than 12 weeks from exposure to HAV often demonstrate anti-HAV IgM titers too low to be useful as a positive control. A low titer stock of anti-hepatitis A (HAV-IgM) with a signal-to-cut-off ratio of -3 is abundantly available. It requires at least a 5-fold enrichment before it can be used in medical diagnostic devices. In order to achieve this goal, we have developed a simple two-step process for enrichment. The first step consists of a fractionation of plasma proteins by ammonium sulfate (A/S) precipitation. The second step is the use of a Pellicon concentrator of molecular weight cut-off of 500 kD. Identity of the enriched anti-HAV IgM product was evaluated by SDSPAGE and Western blotting. The functionality of IgM was evaluated by ELISA, Abbott AxSYM HAVAB-M 2.0, Abbott AxSYM HAVAB 2.0, DiaSorin ETI-HAIGMK PLUS, and DiaSorin ETI-AB-HAVK PLUS assays. The enriched anti-HAV IgM was formulated in normal human plasma and was found to be stable for 11 days at 37°C. This was translated to 15 months of stability at 2-8°C by the Arrhenius plotting model (Kannen 1964). In addition to the enriched anti-HAV IgM product, the process should be amenable to production of IgM-positive controls from low-titer anti-HBcore IgM anti-Toxoplasma IgM, and anti-CMV IgM plasma, as well as from other disease-state plasma where high titer IgM plasma is in short supply.

description: 
There is an abundance of outcomes research for clinical hypnosis showing promising results. Nonetheless, hypnosis is still underutilized in clinical care. For a behavioral intervention to enter mainstream clinical care, efficacy needs to be demonstrated with exceptionally high quality of evidence, and its reporting needs to be complete and sufficiently clear to enable replication and clinical use. The present article provides best practice guidelines formulated by the Task Force for Establishing Efficacy Standards for Clinical Hypnosis for conducting and reporting clinical hypnosis research.The recommendations are presented in two tiers. Tier I recommendations include essential best practices, such as a call for the use of detailed research and intervention manuals, plans for and reporting of participant-education about hypnosis, the use of hypnotizability scales with good psychometric properties, and clear reporting of the hypnotizability measurement. Tier I also includes the sharing of intervention manuals, the reporting of the induction procedure, the labeling of the intervention for participants, and the definition of hypnosis used. Tier II includes preferred recommendations, calling for measurement of adherence to home practice, measurement of hypnotizability using scales with both subjective and behavioral measures of responsiveness, and the involvement of participants from the full hypnotizability spectrum. Tier II also includes the assessment of variables related to proposed mechanisms of action, the reporting of participants prior hypnosis experiences, and the relationship of expectancies and treatment outcomes.This list of recommendations will be useful for researchers, reviewers, and journal editors alike when conducting, reporting, or evaluating studies involving clinical hypnosis.
The Construction of Gender in Contemporary Magazine Advertisements.
Creators: name: Lay, Taylor
Publisher: name: My University
Year: 2017

description: The advertising industry has historically legitimatized differences between the sexes by portraying gender norms in both idealized and stereotypical ways. With the media providing insight into acceptable social norms, and with greater visibility of diverse forms of gender expression emerging today, the study sought to explore whether the mass media is welcoming of contemporary understandings of gender that differ from the anticipated behaviours stemming from the gender binary system. Through the examination of traditional gender stereotypes in contemporary print advertising, the study analyzed how advertisements portray gender in 2017, how advertising helps society understand contemporary gender norms, and if the depictions of gender differ between representations found in American and Canadian magazines. The study utilized the theoretical underpinnings of Peter Berger and Thomas Luckmann’s theory of social constructionism and Albert Bandura’s social learning theory as a way to examine dominant gender norms and how they are perpetuated in society by processes of socialization and reinforcement. Both theories were also used to study the role the media plays in reinforcing or destigmatizing traditional gender norms. Through a content analysis that drew inspiration from the coding framework from Erving Goffman’s (1979) historically acclaimed research on gender and advertising, as well as several modernized coding categories, the study examined 133 print advertisements found within the summer editions of two Canadian magazine publications, FASHION and Sharp, and two American magazine publications, Cosmopolitan and GQ. Notably, the study revealed that with greater trends of metrosexuality and effeminacy in men, stereotypes associated with traditional masculinity are being reduced at greater degrees in advertising than feminine stereotypes. Furthermore, the findings revealed that Canadian advertisements were more likely to be progressive in their representation of gender by including gender diverse individuals in their advertisements more often than American publications. The implications of the study reveal that traditional gender norms and stereotypes may be relaxing and advertising may be becoming more tolerant of gender diversity, but stigmas are not disappearing entirely. It can be anticipated that with greater understanding and educative efforts, the visibility of gender diverse individuals in advertisements will become more commonplace.

DEATH ANXIETY AND PERSONIFICATIONS OF DEATH IN FILM

Publisher: name: Maryland Shared Open Access Repository
Year: 2002

description: For nearly a century movies have played an important role in reflecting American cultural values and norms. During that time technological changes have increased the effective life of a film to unimaginable lengths beyond the original theatre circuit. Since film has become an artistic, audio/visual reflection of American society, it is not surprising that it reveals society's fears and taboos. Film contains symbols of our fears, anxieties, and personifications of death. Although film has been studied since its inception, the thanatological aspects and perspectives of the medium have been largely unexplored. Knowledge of the representations of death issues and death anxiety in film gives the thanatologist a framework for choosing appropriate films for death education as well as bereavement support. Death-stimuli in films was operationalized as either factors found in death anxiety (Durlak and Kass, 1981) or personifications of death (Kastenbaum and Anisenberg, 1972; Kastenbaum and Herman, 1997). Two-hundred and thirty-five films as diverse as Death Takes a Holiday (1934), All That Jazz (1979), Dream with the Fishes (1997), and Memento (2001) were reviewed revealing a trend towards an avoidance of death anxiety elements or issues associated with a long dying trajectory, and a new personification of death with Death as The Mentor found in some films where a long dying trajectory is portrayed.
Modeling the Multi-band Afterglows of GRB 060614 and GRB 060908: Further Evidence for a Double Power-Law Hard Electron Energy Spectrum

description: Electrons accelerated in relativistic collisionless shocks are usually assumed to follow a power-law energy distribution with an index of $p$. Observationally, although most gamma-ray bursts (GRBs) have afterglows that are consistent with $p>2$, there are still a few GRBs suggestive of a hard ($p<2$) electron energy spectrum. Our previous work showed that GRB 091127 gave strong evidence for a double power-law hard electron energy (DPLH) spectrum with $12$ and an "injection break" assumed as $γ_{\rm b}\propto γ^q$ in the highly relativistic regime, where $γ$ is the bulk Lorentz factor of the jet. In this paper, we show that GRB 060614 and GRB 060908 provide further evidence for such a DPLH spectrum. We interpret the multi-band afterglow of GRB 060614 with the DPLH model in an homogeneous interstellar medium by taking into account a continuous energy injection process, while for GRB 060908, a wind-like circumburst density profile is used. The two bursts, along with GRB 091127, suggest a similar behavior in the evolution of the injection break, with $q\sim0.5$. Whether this represents a universal law of the injection break remains uncertain and more such afterglow observations are needed to test this conjecture.

description: En este artículo busco generar una reflexión sobre la sobrevivencia de la selva amazónica, contrastando la orientación hacia la vida que tienen las prácticas y conocimientos indígenas en oposición a la orientación hacia la muerte característica del capitalismo occidental. La expansión destructiva que asola a la Amazonia y sus pueblos en la actualidad es un aspecto del biopoder y busca la substitución de un paisaje selvático por otro que se puede controlar y en el que predominan gramíneas y ganado. Esta substitución implica arrasar con la selva, la cual es producto del trabajo indígena desde al menos hace 14 mil años, que ha manejado y favorecido a ciertas especies de árboles productores de frutos que sirven de alimento para diversos animales y peces. De este modo, los indígenas trabajan conscientemente para la cosmoproducción, actitud que creó el paisaje selvático por medio de nodos vitales, lugares donde se concentran estas especies de árboles. La destrucción de estas conexiones vitales pone en peligro a la Amazonia y esta apenas podrá sobrevivir a la embestida capitalista si los indígenas continúan aplicando sus conocimientos.
description: This article reflects on the survival of the Amazon forest by contrasting the drive toward life contained in indigenous knowledge and practices to the drive toward death that characterizes western capitalism. The destructive expansion that plagues the Amazon and its peoples today is an aspect of the biopower as it attempts to replace wilderness with a controllable landscape mostly made of grasslands and cattle. Such replacement involves tearing down the forest, itself the product of indigenous work for at least fourteen thousand years by managing and favoring certain fruit-yielding tree species that feed animals and fishes. Indigenous peoples, thus, act consciously toward a cosmoproduction responsible for the making of wilderness by means of vital nodes, places where these tree species are especially concentrated. Destroying these connections endangers the Amazon; its survival from capitalist assault will depend on the continuous application of indigenous knowledge.
Motivated information avoidance in an mHealth weight loss intervention: Associations between unmet behavioral goals and likelihood of viewing program messages

description: 
Background
Program engagement is positively associated with improved outcomes in mobile health (mHealth) interventions, but little is known about which factors may increase or decrease the likelihood of participants viewing program messages. This study examined the association between daily behavioral goal achievement and likelihood of reading daily messages, and if this relationship is moderated by baseline depressive symptoms in an mHealth weight loss intervention.

Methods
Data come from a 12-week microrandomized pilot mHealth weight management trial that tested the effects of daily messages on behavioral goals among 52 young adults (78.8% female, 61.5% white, ages 21–35). Conditional growth curve modeling was used to regress message viewing indicators onto the number of daily behavioral goals that participants had not met at the time of message receipt, with testing for moderation by depressive symptoms and controlling for covariates clustered within participants over time.

Results
For each additional goal not met at the time of message receipt, participants were 34.8% less likely to read any message sent (p < 0.0001), and this relationship did not appear to be related to depressive symptoms (p = 0.1).

Conclusions
Participants may tend to avoid reading program messages when they know they are not meeting goals in a program, possibly due to motivated information avoidance to prevent negative emotional reactions from anticipated negative feedback messages. Future interventions may want to consider ways to contact participants who may be struggling in programs and also avoiding viewing standard message pushes in order to reduce the risk of disengagement.

description: We develop a bit-reversible implementation of Milne's Fourth-order Predictor algorithm so as to generate precisely time-reversible simulations of irreversible processes. We apply our algorithm to the collision of two zero-temperature Morse-potential balls, which collide to form a warm liquid oscillating drop. The oscillations are driven by surface tension and damped by the viscosities. We characterize the "important" Lyapunov-unstable particles during the collision and equilibration phases in both time directions to demonstrate the utility of the Milne algorithm in exposing "Time's Arrow".

description: According to the United Nations and World Health Organization Expert Panel, probiotics are defined as "live microorganisms which when administered in adequate amounts confer a health benefit on the host." The present study was conducted to determine whether introducing the probiotic, Pediococcus acidilactici to the diet of goldfish (Carussius auralus) confer health benefits when fish undergo induced stress. Two types of stress were induced one was a physical stress condition mimicking stress associated with the handling of fish. The second condition is a physical and biological stress, involving exposure of the fish to a common fish pathogen, Ichthyopthirius multifilis, in addition to the handling stress. The results demonstrated that fish whose diets are supplemented with 0.1% (w/w) of Pediococcus acidilactici have reduced mortality rates associated with the physical stress condition of handling, and decreased mortality rates associated with the biological and physical stress condition of exposure to the pathogen, Ichthyopthirius multifilis.

description: Antibodies generated in response to influenza vaccine or virus exposure can be detected by the Hemagglutination Inhibition Assay (HAT). Avian influenza strains are more difficult to test than seasonal strains. Previous improvements to the assay include use of horse blood instead of turkey blood. The following experiment used a Design of Experiments (DOE) in an attempt to further optimize the assay by analyzing both serum preparation and assay variables. Phase 1 considered some of the conditions for pretreating test serum: heat inactivation, adsorption with red blood cells, and percentage of Receptor Destroying Enzyme (RDE). Phase 2 examined the assay variables of virus incubation time, temperature, and the percentage of bovine serum albumin (BSA) in buffer, virus, and red blood cells. Phase 3 compared the suggested protocol with the current protocol. The suggested modifications were not found to impact the sensitivity of the assay when examined with reference or experimental sera.

The main results are as follows: When the curvature of the ambient space is positive, there exists a unique such surface up to rigid motions of the target space. On the other hand, when the curvature of the ambient space is negative, there are `non-trivial' complete parallel mean curvature surfaces generated by Jacobi elliptic functions and they exhaust such surfaces.

description: This study examines the mechanism underlying one way in which bumblebees are known to develop a preference for symmetric patterns: through prior non-differential reinforcement on simple patterns (black discs and white discs). In three experiments, bees were given a choice among symmetric and asymmetric black-and-white non-rewarding patterns presented at the ends of corridors in a radial maze. Experimental groups had prior rewarded non-discrimination training on white patterns and black patterns, while control groups had no pre-test experience outside the colony. No preference for symmetry was obtained for any of the control groups. Prior training with circular patterns highlighting a horizontal axis of symmetry led to a specific subsequent preference for horizontal over vertical symmetry, while training with a vertical axis abolished this effect. Circles highlighting both axes created a general avoidance of asymmetry in favour of symmetric patterns with vertical, horizontal or both axes of symmetry. Training with plain circles, but not with deformed circles, led to a preference for symmetry: there was no evidence that the preference emerged just by virtue of having attention drawn away from irrelevant pattern differences. Our results point to a preference for symmetry developing gradually through first learning to extract an axis of symmetry from simple patterns and subsequently recognizing that axis in new patterns. They highlight the importance of continued learning through non-differential reinforcement by skilled foragers. Floral guides can function not only to guide pollinators to the source of reward but also to highlight an axis of symmetry for use in subsequent floral encounters.

description: This paper investigates the relationship between committed foreign aid and right light data from 1992 to 2008. Two aid data classifications were used: (i) humanitarian, early impact, late impact, and other aid and (ii) humanitarian and non humanitarian aid. The results show that the elasticity of our measure of night lights to humanitarian aid is negative and statistically significant at the 5% level for year 0 and 1 and statistically insignificant for year 2 onwards. The elasticities for early impact, late impact and non humanitarian aid are positive and statistically significant for year 1 and onwards. Foreign aid positively impact night light data and suggestively imply that foreign aid positively impact, albeit weakly economic activity. The heterogeneity of the results was investigated. The results were not sensitive to a change from non calibrated satellite images but did differ depending on the percentage electrification of a country, percentage of the total population that live in urban environments, and the initial level of prosperity of a country.

description: Mechanical and tribotechnical features of powdered materials are strongly influenced by pore volume, fracture character, impurities, alloying, concentration inhomogeneity, friction conditions and other factors. Pores also influence on acceleration of diffusion processes, reduce undercooled austenite resistance. To study porous iron features was used ultrapure additionally annealed in hydrogen powder. Toughness fracture and tribotechnical features had nonmonotonic dependence from porosity different from all known dependences got from technical iron powders. Researches brought out the fact that in process of porosity reduction by pressing and annealing cycles, the average dimension of porous is changed. According to the analysis of porous structure were created models of friction, wear and fracture of pure porous iron.

description: Abstract: "A concurrent object is a data structure shared by concurrent processes. This paper describes in detail a simulation package for simulating, testing, and analyzing implementations of concurrent objects. We use linearizability as our fundamental correctness condition, thereby exploiting the semantics of the object's type to enhance the degree of concurrency allowed. The simulator determines for a finite history of operations executed on a concurrent object whether the history is linearizable. The user can give the simulator a finite set of input test histories or let the simulator generate and test an unbounded number."

We show that it is possible to find static solutions of the form of charged dS/AdS-like black hole with horizon which could have a negative mass parameter. The motion of the 3-brane in this bulk generates an effective 4-dimensional bouncing cosmology induced by the negative dark radiation term. This model avoids the instability that arises for bouncing brane in a Reissner-Nordstrøm-AdS bulk.

Monetary Policy Transmission in Canada: A FAVAR Analysis
Creators: name: Ji, Jiangnan
Publisher: name: My University
Year: 2017

description: This paper employs the Factor Augmented Vector Autoregression (FAVAR) method used in Boivin, Giannoni and Stevanovic (2010) to analyze traditional channels of monetary policy transmission in Canada and to estimate the industrial and provincial effects of monetary policy. The benchmark model includes 409 quarterly macroeconomic time series from 1981Q2 to 2016Q2. The impulse response results are broadly consistent with the theoretical prediction of a small open economy model, except for CPI and total exports that are relatively nonresponsive to the monetary policy shock. The identified monetary policy shocks have heterogeneous sectorial effects, which are the largest for industrial GDP in manufacturing and wholesale trade, and for employment in manufacturing and construction. Furthermore, this paper finds that there are provincial differences in the responses to monetary policy shocks, with employment in Quebec and Ontario and housing price in Ontario and British Columbia being the most affected.

description: Nickel, cadmium, and chromium are toxic industrial chemicals with an exposure risk, found in military, occupational, and environmental settings. While the substances are known to have adverse health effects, the exact mechanisms of toxicity remain unclear and a paucity of biomarkers of exposure and effect exist. To identify candidate biomarkers and to elucidate the mechanisms of toxicity of Ni, Cr, and Cd, H4-II-E-C3 and MH1C1 rat liver-derived cell lines were treated with various concentrations of each metal and gene expression patterns were determined through the use of an Affymetrix microarray and analyzed using bioinformatic tools including Ingenuity Pathway Analysis. A total of 992 probe sets were differentially expressed as a result of exposure to nickel, chromium, and/or cadmium, 246 of which may be further investigated as candidate biomarkers. The modulated genes were involved in biological processes such as the oxidative stress response, apoptosis, cell cycle regulation, and hypoxia.
Massive Nambu-Goldstone Fermions and Bosons for Non-relativistic Superconformal Symmetry: Jackiw-Pi Vortices in a Trap

description: We discuss a supersymmetric extension of a non-relativistic Chern-Simons matter theory, known as the SUSY Jackiw-Pi model, in a harmonic trap. We show that the non-relativistic version of the superconformal symmetry, called the super-Schrödinger symmetry, is not spoiled by an external field including the harmonic potential. It survives as a modified symmetry whose generators have explicit time dependences determined by the strength of the trap, the rotation velocity of the system and the fermion number chemical potential. We construct 1/3 BPS states of trapped Jackiw-Pi vortices preserving a part of the modified superconformal symmetry and discuss fluctuations around static BPS configurations. In addition to the bosonic massive Nambu-Goldstone modes, we find that there exist massive Nambu-Goldstone fermions associated with broken modified super-Schrödinger symmetry generators. Furthermore, we find that eigenmodes form supermultiplets of a modified supersymmetry preserved by the static BPS backgrounds. As a consequence of the modified supersymmetry, infinite towers of explicit spectra can be found for eigenmodes correspond- ing to bosonic and fermionic lowest Landau levels.

A Simplified Account of the Metatheory of Linear LF

description: We present a variant of the linear logical framework LLF that avoids the restriction that well-typed forms be in pre-canonical form and adds λ-abstraction at the level of families. We abandon the use of β-conversion as definitional equality in favor of a set of typed definitional equality judgments that include rules for parallel conversion and extensionality. We show type-checking is decidable by giving an algorithm to decide denfiitional equality for well-typed terms and showing the algorithm is sound and complete. The algorithm and the proof of its correctness are simplified by the fact that they apply only to well-typed terms and may therefore ignore the distinction between intuitionistic and linear hypotheses.

description: Simulations in the warm dense matter regime using finite temperature Kohn-Sham density functional theory (FT-KS-DFT), while frequently used, are computationally expensive due to the partial occupation of a very large number of high-energy KS eigenstates which are obtained from subspace diagonalization. We have developed a stochastic method for applying FT-KS-DFT, that overcomes the bottleneck of calculating the occupied KS orbitals by directly obtaining the density from the KS Hamiltonian. The proposed algorithm, scales as $O\left(NT^{-1}\right)$ and is compared with the high-temperature limit scaling $O\left(N^{3}T^{3}\right)$ of the deterministic approach, where $N$ is the system size (number of electrons, volume etc.) and $T$ is the temperature. The method has been implemented in a plane-waves code within the local density approximation (LDA); we demonstrate its efficiency, statistical errors and bias in the estimation of the free energy per electron for a diamond structure silicon. The bias is small compared to the fluctuations, and is independent of system size. In addition to calculating the free energy itself, one can also use the method to calculate its derivatives and obtain the equations of state.
A Simple Typeless Language Based on the Principle of Completeness and the Reference Concept

description: GEDANKEN is an experimental programming language with the following characteristics. (1) Any value which is permitted in some context of the language is permissible in any other meaningful context. In particular, functions and labels are permissible results of functions and values of variables. (2) Assignment and indirect addressing are formalized by introducing values, called references, which in turn possess other values. The assignment operation always affects the relation between some reference and its value. (3) All compound data structures are treated as functions. (4) Type declarations are not permitted. The functional approach to data structures and the use of references insure that any process which accepts some data structure will accept any logically equivalent structure, regardless of its internal representation. More generally, any data structure may be implicit; i.e. it may be specified by giving an arbitrary algorithm for computing or accessing its components. The existence of label variables permits the construction of co-routines, quasi-parallel processes, and other unorthodox control mechanisms. A variety of programming examples illustrates the generality of the language. Limitations and possible extensions are discussed briefly.
Críticas al mutuo disenso tácito como mecanismo frente al incumplimiento recíproco de los contratos bilaterales

description: El vacío normativo de que adolece el régimen jurídico contractual colombiano en cuanto al fenómeno del incumplimiento mutuo de los contratos bilaterales y la forma de solucionar la parálisis del tracto negocial que con ello se genera, ha sido objeto de múltiples discusiones en el campo académico y judicial. Desde la aproximación al origen de la figura del contrarius consensus y su reconocimiento en las legislaciones civiles contemporáneas, pasando por las diversas posturas asumidas por la jurisprudencia nacional al resolver los casos en que se da tal supuesto de hecho, el presente trabajo busca evidenciar las razones por las cuales el mutuo disenso tácito deviene inadecuado como remedio ante el incumplimiento recíproco de los contratos bilaterales, de cara a la tradición romanista y la primacía del sinalagma en la totalidad del iter contractual.

From the approach to the origin of the figure of the contrarius consensus and its recognition in contemporary civil legislations, through the different positions assumed by the national jurisprudence when solving the cases in which such a factual assumption occurs, the present work seeks to evidence the reasons why the tacit mutual dissent becomes inadequate as a remedy for the reciprocal breach of bilateral contracts, in view of the Romanist tradition and the primacy of the synalagma in the totality of the contractual iter

SHAPING SOUND: AN AESTHETIC AND ACOUSTICAL EXPLORATION OF CERAMIC BELLS
Creators: name: Petke, Cameron
Publisher: name: Maryland Shared Open Access Repository
Year: 2009

description: Shaping Sound is a comprehensive exploration of the aesthetic and acoustical variables involved in making clear-ringing contemporary ceramic bells. The first component of the research is devoted to the history of bell-making and the cultural significance that bells have held throughout history. The second component explores the artist's personal aesthetic inspiration and intentions. The third component is a study of bell acoustics and the identification and testing of the variables that impact the sound quality of ceramic bells. Design variations on wall thickness, proportions, profile, surface ornamentation, and surface-finish were evaluated using computerized recording and analysis software. Experiments were also conducted to determine how clay body type and firing temperatures impact bell acoustics. The results led to the design and exhibition of a collection of wheel-thrown ceramic bells with long-ringing and clear tones, an aesthetic connection to Eastern bronze temple-bells, and a highly polished marble-like surface quality.
