description: We propose a natural quantized character theory for inductive systems of compact quantum groups based on KMS states on AF-algebras following Stratila-Voiculescu's work (Stratila-Voiculescu, 1975) (or (Enomoto-Izumi, 2016)), and give its serious investigation when the system consists of quantum unitary groups $U_q(N)$ with $q$ in $(0,1)$. The key features of this work are: The "quantized trace" of a unitary representation of a compact quantum group can be understood as a quantized character associated with the unitary representation and its normalized one is captured as a KMS state with respect to a certain one-parameter automorphism group related to the so-called scaling group. In this paper we provide a Vershik-Kerov type approximation theorem for extremal quantized characters (called the ergodic method) and also compare our quantized character theory for the inductive system of $U_q(N)$ with Gorin's theory on $q$-Gelfand-Tsetlin graphs (Gorin, 2012).

description: A 6bit flash-ADC with 1.2GSps, wide analog bandwidth and low power, realized in a standard digital 0.13 $μ$m CMOS copper technology is presented. Employing capacitive interpolation gives various advantages when designing for low power: no need for a reference resistor ladder, implicit sample-and-hold operation, no edge effects in the interpolation network (as compared to resistive interpolation), and a very low input capacitance of only 400fF, which leads to an easily drivable analog converter interface. Operating at 1.2GSps the ADC achieves an effective resolution bandwidth (ERBW) of 700MHz, while consuming 160mW of power. At 600MSps we achieve an ERBW of 600MHz with only 90mW power consumption, both from a 1.5V supply. This corresponds to outstanding Figure-of-Merit numbers (FoM) of 2.2 and 1.5pJ/convstep, respectively. The module area is 0.12mm^2.

description: This article is devoted to systematic analysis of double charmonium production in exclusive $Z$ boson decays in the framework of Nonrelativistic Quantum Chromodynamic (NRQCD) and leading twist light-cone (LC) models. Theoretical predictions for branching fractions of all considered decays are presented. According to obtained results in the case of allowed by helicity suppression rule processes the effect of internal quark motion increases the branching fraction by a factor 1.5, while for forbidden reactions LC predictions are strictly zero, while NRQCD ones are significantly smaller than for allowed.

description: Lange Zeit waren Städte Hotspots gebietsfremder Arten. Mit dem Klimawandel wird das Invasionspotential nicht-heimischer Arten steigen und Städte werden immer mehr zu Ausbreitungszentren von Exoten in die freie Landschaft. Die Diversität dieser exotischen Arten in Städten bleibt weiterhin hoch und auch bei der Erhaltung eines erträglichen Innenstadtklimas setzt man vermehrt v.a. auch bei Bäumen auf nicht indigene Arten. Climate change and alien invasive species in urban habitats: For a long time, cities have been hotspots of alien species. With climate chance invasion potential of aliens will rise and cities will be transformed to centers of spontaneous spread from the city to the countryside. Diversity of alien species in urban areas will stay high due to the fact that many planted trees (beneficial for inner city climate) are non-indigenous species.

description: We have previously presented a new one parameter family of algorithms and a program for evaluation the first m derivatives of a polynomial of degree n. In this paper we analyze that family of algorithms and present practical algorithms for selecting optimal or good values of the parameter q. A program for selection the optimal value of q under the constraint that q divides n+1 is given. We also analyze a program that eliminates that constraint and a simple program that selects a good, but not always optimal, value of q. We derive bounds on how close to optimal the "good" value will be. The above results apply for n >12. We extend the results to all n by tabulating the cost function for n ≤ 12. Some open questions on extensions of our results are stated.

description: A 12 bit Pipeline ADC fabricated in a 0.18 $μ$m pure digital CMOS technology is presented. Its nominal conversion rate is 110MS/s and the nominal supply voltage is 1.8V. The effective number of bits is 10.4 when a 10MHz input signal with 2V_{P-P} signal swing is applied. The occupied silicon area is 0.86mm^2 and the power consumption equals 97mW. A switched capacitor bias current circuit scale the bias current automatically with the conversion rate, which gives scaleable power consumption and full performance of the ADC from 20 to 140MS/s.

description: Virtual element methods is a new promising finite element methods using general polygonal meshes. Its optimal a priori error estimates are well established in the literature. In this paper, we take a different viewpoint. We try to uncover the superconvergent property of the virtual element methods by doing some local post-processing only on the degrees of freedom. Using linear virtual element method as an example, we propose a universal recovery procedure to improve the accuracy of gradient approximation for numerical methods using general polygonal meshes. Its capability of serving as a posteriori error estimators in adaptive methods is also investigated. Compared to the existing residual-type a posteriori error estimators for the virtual element methods, the recovery-type a posteriori error estimator based on the proposed gradient recovery technique is much simpler in implementation and asymptotically exact. A series of benchmark tests are presented to numerically illustrate the superconvergence of recovered gradient and validate the asymptotical exactness of the recovery-based a posteriori error estimator.

description: The effect of mesons $f_{0}(975)$ (named as $f$), $ϕ(1020)$ (named as $ϕ$) and $δ$ on the moment of inertia of the PNS PSR J0348+0432 is examined in the framework of the relativistic mean field theory considering the baryon octet. It is found that the energy density $\varepsilon$ and pressure $p$ will increase considering the mesons $δ$ whereas will decrease as the mesons $f$ and $ϕ$ being considered. When the mesons $f, ϕ$ and $δ$ are considered, the energy density and pressure will all decrease. It is also found that the contribution of mesons $f$, $ϕ$ and $δ$ to the central energy density is only the central energy density's 0.06$\sim$0.6\% whereas the contribution of mesons $f$, $ϕ$ and $δ$ to the central pressure is the central pressure's 4$\sim$7\%. For the radius, it will decrease when the contributions of mesons $f$, $ϕ$ and $δ$ are considered. The moment of inertia $I$ will increase considering the mesons $δ$ whereas will decrease as the mesons $f$ and $ϕ$ being considered. When the mesons $f$, $ϕ$ and $δ$ are all considered, the moment of inertia will decrease. It is found that the contribution of mesons $f$ and $ϕ$ to moment of inertia is 4$\sim$9 times larger than that of mesons $δ$. Our results show that the mesons $f$, $ ϕ$ and $δ$ contribute to the moment of inertia's 2$\sim$5\%.

description: Abstract

Slope failures are very common natural problems in the mountainous terrain due to the steep topography, improper landuse and adverse climatic conditions. In every geohazard study, detailed investigation on the geological structures, surface features and other related variables will be carried out. This paper discuss the impacts of geological and weathering properties as environmental factors for assessing slope failures in mountainous terrain. A case study from Dam Thuy commune, Trung Khanh county, Cao Bang province is used to illustrate the dynamic interaction between landsliding factors and slope failures. Regional survey results include underlying geology, surface forms and features, and weathering process in study area. Methods used to analyse the geologic, geomorphic and weathering characteristics of Backan town area include a combination of remote sensing image interpretation, field mapping, soil/stratigraphic descriptions, and the use of previously published surveys. The collected data then can be combined to create landslide hazard and risk maps for study area.

description: The 30 Doradus star-forming region in the Large Magellanic Cloud is a nearby analogue of large star-formation events in the distant Universe. We determine the recent formation history and the initial mass function (IMF) of massive stars in 30 Doradus based on spectroscopic observations of 247 stars more massive than 15 solar masses ($\mathrm{M}_\odot$). The main episode of massive star formation started about $8\,\mathrm{Myr}$ ago and the star-formation rate seems to have declined in the last $1\,\mathrm{Myr}$. The IMF is densely sampled up to $200\,\mathrm{M}_\odot$ and contains $32\pm12\%$ more stars above $30\,\mathrm{M}_\odot$ than predicted by a standard Salpeter IMF. In the mass range $15-200\,\mathrm{M}_\odot$, the IMF power-law exponent is $1.90^{+0.37}_{-0.26}$, shallower than the Salpeter value of 2.35.

description: We study the time evolution of a system of fermions with pairing interactions at a finite temperature. The dynamics is triggered by an abrupt increase of the BCS coupling constant. We show that if initially the fermions are in a normal phase, the amplitude of the BCS order parameter averaged over the Boltzman distribution of initial states exhibits damped oscillations with a relatively short decay time. The latter is determined by the temperature, the single-particle level spacing, and the ground state value of the BCS gap for the new coupling. In contrast, the decay is essentially absent when the system was in a superfluid phase before the coupling increase.

Prepotentials for linearized supergravity

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Linearized supergravity in arbitrary dimension is reformulated into a first order formalism which treats the graviton and its dual on the same footing at the level of the action. This generalizes previous work by other authors in two directions: 1) we work in arbitrary space-time dimension, and 2) the gravitino field and supersymmetry are also considered. This requires the construction of conformally invariant curvatures (the Cotton fields) for a family of mixed symmetry tensors and tensor-spinors, whose properties we prove (invariance; completeness; conformal Poincaré lemma). We use these geometric tools to solve the Hamiltonian constraints appearing in the first order formalism of the graviton and gravitino: the constraints are solved through the introduction of prepotentials enjoying (linearized) conformal invariance. These new variables (two tensor fields for the graviton, one tensor-spinor for the gravitino) are injected into the action and equations of motion, which take a geometrically simple form in terms of the Cotton tensor(-spinors) of the prepotentials. In particular, the equations of motion of the graviton are equivalent to twisted self-duality conditions. We express the supersymmetric transformations of the graviton and gravitino into each other in terms of the prepotentials. We also reproduce the dimensional reduction of supergravity within the prepotential formalism. Finally, our formulas in dimension five are recovered from the dimensional reduction of the already known prepotential formulation of the six-dimensional $\mathcal{N}=(4,0)$ maximally supersymmetric theory.

description: A new interstellar molecular ion, H2COH+ (protonated formaldehyde), has been detected toward Sgr B2, Orion KL, W51, and possibly in NGC 7538 and DR21(OH). Six transitions were detected in Sgr B2(M). The 11,0-10,1 transition was detected in all sources listed above. Searches were also made toward the cold, dark clouds TMC-1 and L134N, Orion (3N, 1E), and a red giant, IRC +10216, without success. The excitation temperatures of H2COH+ are calculated to be 60-110 K, and the column densities are on the order of 1012-1014 cm-2 in Sgr B2, Orion KL, and W51. The fractional abundance of H2COH+ is on the order of 10-11 to 10-9, and the ratio of H2COH+ to H2CO is in the range 0.001-0.5 in these objects. The values in Orion KL seem to be consistent with the "early time" values of recent model calculations by Lee, Bettens, & Herbst, but they appear to be higher than the model values in Sgr B2 and W51 even if we take the large uncertainties of column densities of H2CO into account. We suggest production routes starting from CH3OH may play an important role in the formation of H2COH+.

description: A sorting network (also known as a reduced decomposition of the reverse permutation), is a shortest path from $12 \cdots n$ to $n \cdots 21$ in the Cayley graph of the symmetric group $S_n$ generated by adjacent transpositions. We prove that in a uniform random $n$-element sorting network $σ^n$, all particle trajectories are close to sine curves with high probability. We also find the weak limit of the time-$t$ permutation matrix measures of $σ^n$. As a corollary of these results, we show that if $S_n$ is embedded into $\mathbb{R}^n$ via the map $τ\mapsto (τ(1), τ(2), \dots τ(n))$, then with high probability, the path $σ^n$ is close to a great circle on a particular $(n-2)$-dimensional sphere in $\mathbb{R}^n$. These results prove conjectures of Angel, Holroyd, Romik, and Virag.

The approach advantages are the ability to protect the core IP, the simple test interface (thanks also to the adoption of the P1500 standard), the possibility to run the test at-speed, the reduced test time, and the good diagnostic capabilities. The paper reports figures about the achieved fault coverage, the required area overhead, and the performance slowdown, and compares the figures with those for alternative approaches, such as those based on full scan and sequential ATPG.

description: Die Umweltbedingungen für Pflanzen in Städten sind vor allem durch erhöhte Temperaturen (städtische Wärmeinsel), einem hohem Versiegelungsgrad, hohem Störungsgrad und hoher Dynamik geprägt. Das Stadtklima wirkt sich auf die Phänologie vieler Arten aus, die in Städten z.B. früher blühen als im Umland, außerdem werden wärmeliebende Arten häufig gefördert. Eine weitere Reaktion sind Arealverschiebungen, z.B. des Schilfrohrs und immergrüner Gehölze. Evolutionäre Prozesse können in urbanen Räumen beschleunigt werden. Urbane Floren können sich in Richtung erhöhter Anteile wärmeliebender Neophyten verschieben. Die spontane Stadtflora kann gut auf Veränderungen reagieren und sich anpassen, sie wird aber zurückgedrängt, daher muss gepflanzte Stadtvegetation wohl durchdacht sein. Einflüsse auf die Vegetation durch den Klimawandel sind von denen der Urbanisierung oftmals schwer zu trennen. Plant reactions to the urban climate: Environmental conditions for plants in urban areas are characterised by higher temperatures (urban heat island), high degrees of soil sealing, disturbance as well as by a highly dynamic environment. Urban climate affects the phenology of several plant species and often favours thermophilic species. Furthermore, plant species‘ ranges can shift as a reaction to urban climate. In urban areas evolutionary processes can be accelerated and urban floras harbour more and more thermophilic non-native species. The spontanously occuring flora is able to adapt to changes, but it is threatened by human activities. Therefore, planted vegetation has to be thoroughly planned. Effects on vegetation by climate change and ur- banisation are often difficult to distinguish

In particular, we take into account the details of surface reconstruction by means of well relaxed crystal structures. The surface electronic states are identified and the local density of states is compared to recent data from scanning tunneling spectroscopy. We obtain almost perfect agreement between theory and experiment for both the occupied and unoccupied states, which allows us to clarify the interpretation of the experimental data.

description: In this paper, we introduce MyCampus, an agent-based environment for context-aware mobile services, which we are in the process of developing and validating on Carnegie Mellon University’s campus. The environment re-volves around a growing collection of customizable agents capable of (semi-) automatically discovering and accessing user personal resources (e.g. calendar, location tracking functionality, food preferences) and Web services as they assist their users in carrying out different tasks such as planning an evening out, orga-nizing a study group or filtering incoming messages. The openness of the MyCampus architecture directly derives from a set of on-tologies for describing personal resources, contextual attributes, user preferences and web services. Contextual information and other personal details about a user are accessed via a Semantic e-Wallet, subject to access privileges set by the user. Over time, the user can pull new agents into her context and assume that these agents will automatically be able to discover and access relevant contextual in-formation and personal details. Similarly, service ontologies facilitate the intro-duction of new Web services by allowing agents to (semi-)automatically dis-cover and access them. Such openness could one day play a key role in helping create a more leveled playing field for producers of Web services. It could also open the door to new markets for a wide variety of simple, task-specific agents capable of automatically adapting to their user’s context and preferences.

The Psychological Salience of Social Identities: Interpretations of Situations for Implicit Measurement
Creators: name: Ebiringah, Onyedikachi
Publisher: name: University of Illinois at Chicago
Year: 2024

description: A study examining the influence of explicit and implicit priming on sociodemographic identity salience utilizing a time forced choice survey was conducted to evaluate if priming can induce and heighten the accessibility and availability of identity related schemas. An online survey administered through Prolific was given to two groups totaling 292 participants. The survey consisted of 20 target items and 40 fillers items that served to diminish the effects of priming. The order with which the questions were presented differed across conditions. Participants also completed the Everyday Discrimination Scale to measure perceived levels of discrimination across experimental groups.
 Statistically the groups did not differ in their choice of racial/ethnicity sociodemographic answer choices, nor did they differ in their scores on the Everyday Discrimination scale. Also, there was no significant interaction of participant gender and sociodemographic race/ ethnicity answer choice. However, findings did indicate statistical significance in participants who identified as non-Spiritual or Liberal did choose race/ ethnicity sociodemographic answer more often than those who did not.
 Implications for future assessment methods, improvement to study design, and methodological scope are further considered and discussed.

description: Stadtbewohner sind von Hitzewellen, die in Folge des Klimawandels häufiger, intensiver und länger auftreten, stärker betroffen als Bewohner auf dem Land. Die während des Tages aufgeheizten Gebäude in Städten kühlen nachts weniger stark aus als Gebäude im geringer verdichteten Umland. Dadurch wird das bereits beanspruchte Thermoregulationssystem des Körpers zusätzlich gefordert und nächtliche Ruhephasen werden verkürzt. Anhaltend hohe Temperaturen wirken auf diese Weise besonders belastend auf den menschlichen Körper. In Deutschland verstarben 2003 ca. 7.600 Menschen an den Folgen hitzebedingter Gesundheitsbelastung. Um auf bevorstehende Hitzewellen rechtzeitig reagieren zu können und Maßnahmen für den Gesundheitsschutz einzuleiten, hat sich das Hitzewarnsystem des Deutschen Wetterdienstes etabliert. Die besondere Belastung in Städten infolge des Effekts der Städtischen Wärmeinsel wird seit 2017 bei Hitzewarnungen besonders berücksichtigt. Untersuchungen in Berlin und Brandenburg haben ergeben, dass während der Hitzewelle 1994 die höchsten Abweichungen der Mortalität vom Erwartungswert in den am dichtesten bebauten Gebieten Berlins auftraten. Um zukünftig mit den intensiveren Hitzewellen umgehen zu können und Gesundheitsrisiken zu vermeiden, sollten daher insbesondere im städtischen Raum Anpassungsmaßnahmen entwickelt werden. Heat waves and heat warnings in cities: Urban dwellers are more affected by heat waves, which will occur more frequently, more intensively and will last longer as a result of climate change, than rural dwellers. The buildings in cities that are heated during the day cool down less at night than buildings in less densely populated areas. This places additional demands on the body‘s already stressed thermoregulation system and shortens rest periods at night. In this way, persistently high temperatures have a particularly stressful effect on the human body. In Germany, around 7600 people died in 2003 as a result of heat-related health problems. The heat warning system of the German Meteorological Service has established itself in order to be able to react in time to impending heat waves and to initiate measures for health protection. Since 2017, the specific heat stress in cities due to the Urban-Heat-Island effect has been given special consideration in heat warnings. Studies in Berlin and Brandenburg have revealed that during the heatwave in 1994 the highest deviation of mortality from the expected value occurred in the most densely built-up areas of Berlin. In order to be able to deal with the more intense heat waves in the future and to avoid health risks, adaptation measures should therefore be developed, especially in urban areas.

description: Characterizations of entire subsolutions for the 1-harmonic equation of a constant 1$-tension field are given with applications in geometry via transformation group theory. In particular, we prove that every level hypersurface of such a subsolution is calibrated and hence is area-minimizing over $\mathbb{R}$; and every 7-dimensional $SO(2)\times SO(6)$-invariant absolutely area-minimizing integral current in $\mathbb{R}^8$ is real analytic. The assumption on the $SO(2) \times SO(6)$-invariance cannot be removed, due to the first counter-example in $\mathbb{R}^8$, proved by Bombieri, De Girogi and Giusti.

description: We report the discovery of a massive (Mpsini = 13.02 +/- 0.64 Mjup; total mass 13.25 +/- 0.64 Mjup), large (1.95 +/- 0.16 Rjup) planet in a transiting, eccentric orbit (e = 0.260 +/- 0.017) around a 10th magnitude F5V star in the constellation Camelopardalis. We designate the planet XO-3b, and the star XO-3, also known as GSC 03727-01064. The orbital period of XO-3b is 3.1915426 +/- 0.00014 days. XO-3 lacks a trigonometric distance; we estimate its distance to be 260 +/- 23 pc. The radius of XO-3 is 2.13 +/- 0.21 Rsun, its mass is 1.41 +/- 0.08 Msun, its vsini = 18.54 +/- 0.17 km/s, and its metallicity is [Fe/H] = -0.177 +/- 0.027. This system is unusual for a number of reasons. XO-3b is one of the most massive planets discovered around any star for which the orbital period is less than 10 days. The mass is near the deuterium burning limit of 13 Mjup, which is a proposed boundary between planets and brown dwarfs. Although Burrows et al. (2001) propose that formation in a disk or formation in the interstellar medium in a manner similar to stars is a more logical way to differentiate planets and brown dwarfs, our current observations are not adequate to address this distinction. XO-3b is also unusual in that its eccentricity is large given its relatively short orbital period. Both the planetary radius and the inclination are functions of the spectroscopically determined stellar radius. Analysis of the transit light curve of XO-3b suggests that the spectroscopically derived parameters may be over estimated. Though relatively noisy, the light curves favor a smaller radius in order to better match the steepness of the ingress and egress. The light curve fits imply a planetary radius of 1.25 +/- 0.15 Rjup, which would correspond to a mass of 12.03 +/- 0.46 Mjup.

Subjects: hantavirus infections, Puumala-Orthohantavirus, Myodes glareolus, strong beech masts

description: Die Meldungen von klinisch auffälligen Hantavirus-Infektionen bei Menschen lagen in Deutschland von 2001 bis 2003 bei 106 bis 172 Fällen pro Jahr. Seit 2005 sind die Meldungen schwankend aber deutlich angestiegen; der höchste Wert wurde 2012 mit 2370 Fällen registriert. Eine Zunahme der Infektionen wird auch in anderen europäischen Ländern beobachtet. Das Auftreten von Hantaviren ist eng mit Kleinsäugern (u.a. Mäuse, Ratten und Spitzmäuse) assoziiert. Die meisten Fälle werden in Deutschland durch das Puumala-Orthohantavirus (PUUV) verursacht, das von der Rötelmaus (Myodes glareolus) übertragen wird. Die Untersuchungen in Waldgebieten lassen eine Korrelation zwischen der Anzahl der Infektionen und dem Anstieg der Mäusepopulation erkennen. Dies kann z.B. durch Buchenmast bedingt sein. Folgende Gegenden wurden als endemische Gebiete für PUUV-Infektionen identifiziert: Baden-Württemberg, Bayern, Niedersachsen, Nordrhein-Westfalen und Hessen. Hantaviruses: Potential hazard as a result of global warming? – Remarks. The reports of clinically registered human hantavirus infections in Germany were between 106 and 172 cases per year from 2001 to 2003. Since 2005 the numbers of reported cases have been fluctuating but nevertheless were significantly increasing; the highest value was registered in 2012 with 2370 cases. An increase of human infections has also been observed in other European countries. The occurrence of hantaviruses is closely associated with small mammals (including mice, rats and shrews). Most cases in Germany are caused by the Puumala Orthohantavirus (PUUV), which is transmitted by bank voles (Myodes glareolus). The investigations in forest areas revealed a correlation between the number of infections and the increase in mouse populations. This can e.g. be connected with strong beech masts. The following areas have been identified as endemic areas for PUUV infections: Baden-Württemberg, Bavaria, Lower Saxony, North Rhine-Westphalia and Hesse.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Effective Extensible Programming: Unleashing Julia on GPUs

description: GPUs and other accelerators are popular devices for accelerating compute-intensive, parallelizable applications. However, programming these devices is a difficult task. Writing efficient device code is challenging, and is typically done in a low-level programming language. High-level languages are rarely supported, or do not integrate with the rest of the high-level language ecosystem. To overcome this, we propose compiler infrastructure to efficiently add support for new hardware or environments to an existing programming language. We evaluate our approach by adding support for NVIDIA GPUs to the Julia programming language. By integrating with the existing compiler, we significantly lower the cost to implement and maintain the new compiler, and facilitate reuse of existing application code. Moreover, use of the high-level Julia programming language enables new and dynamic approaches for GPU programming. This greatly improves programmer productivity, while maintaining application performance similar to that of the official NVIDIA CUDA toolkit.
Using Mobilize Power Management IP for Dynamic & Static Power Reduction in SoC at 130 nm
Creators: name: Hillman, Dan
Publisher: name: arXiv
Year: 2007
Subjects: subject: Hardware Architecture (cs.AR)
subject: FOS: Computer and information sciences

description: At 130 nm and 90 nm, power consumption (both dynamic and static) has become a barrier in the roadmap for SoC designs targeting battery powered, mobile applications. This paper presents the results of dynamic and static power reduction achieved implementing Tensilica's 32-bit Xtensa microprocessor core, using Virtual Silicon's Power Management IP. Independent voltage islands are created using Virtual Silicon's VIP PowerSaver standard cells by using voltage level shifting cells and voltage isolation cells to implement power islands. The VIP PowerSaver standard cells are characterized at 1.2V, 1.0V and 0.8V, to accommodate voltage scaling. Power islands can also be turned off completely. Designers can significantly lower both the dynamic power and the quiescent or leakage power of their SoC designs, with very little impact on speed or area using Virtual Silicon's VIP Gate Bias standard cells.

description: An optimally efficient explicit numerical scheme for solving fluid dynamics equations, or any other parabolic or hyperbolic system of partial differential equations, should allow local regions to advance in time with their own, locally constrained time steps. However, such a scheme can result in violation of the Courant-Friedrichs-Lewy (CFL) condition, which is manifestly non-local. Although the violations can be considered to be "weak" in a certain sense and the corresponding numerical solution may be stable, such calculation does not guarantee the correct propagation speed for arbitrary waves. We use an experimental fluid dynamics code that allows cubic "patches" of grid cells to step with independent, locally constrained time steps to demonstrate how the CFL condition can be enforced by imposing a condition on the time steps of neighboring patches. We perform several numerical tests that illustrate errors introduced in the numerical solutions by weak CFL condition violations and show how strict enforcement of the CFL condition eliminates these errors. In all our tests the strict enforcement of the CFL condition does not impose a significant performance penalty.

description: The MultiNoC system implements a programmable on-chip multiprocessing platform built on top of an efficient, low area overhead intra-chip interconnection scheme. The employed interconnection structure is a Network on Chip, or NoC. NoCs are emerging as a viable alternative to increasing demands on interconnection architectures, due to the following characteristics: (i) energy efficiency and reliability; (ii) scalability of bandwidth, when compared to traditional bus architectures; (iii) reusability; (iv) distributed routing decisions. An external host computer feeds MultiNoC with application instructions and data. After this initialization procedure, MultiNoC executes some algorithm. After finishing execution of the algorithm, output data can be read back by the host. Sequential or parallel algorithms conveniently adapted to the MultiNoC structure can be executed. The main motivation to propose this design is to enable the investigation of current trends to increase the number of embedded processors in SoCs, leading to the concept of "sea of processors" systems.
