Creating a Digital Ecosystem: Service-Oriented Architectures with Distributed Evolutionary Computing
Creators: name: Briscoe, G
Publisher: name: arXiv
Year: 2007
Subjects: subject: Neural and Evolutionary Computing (cs.NE)
subject: FOS: Computer and information sciences

description: We start with a discussion of the relevant literature, including Nature Inspired Computing as a framework in which to understand this work, and the process of biomimicry to be used in mimicking the necessary biological processes to create Digital Ecosystems. We then consider the relevant theoretical ecology in creating the digital counterpart of a biological ecosystem, including the topological structure of ecosystems, and evolutionary processes within distributed environments. This leads to a discussion of the relevant fields from computer science for the creation of Digital Ecosystems, including evolutionary computing, Multi-Agent Systems, and Service-Oriented Architectures. We then define Ecosystem-Oriented Architectures for the creation of Digital Ecosystems, imbibed with the properties of self-organisation and scalability from biological ecosystems, including a novel form of distributed evolutionary computing.

description: The chemical investigation of the fruits of Xanthium strumarium (Asteraceae) led to the isolation of two new ent-kauranoid glucosides named 2-O-(6-O-isocaleryl-β-D-glucopyranosyl) atractyligenin (1) and 2-O-(2-O-isovaleryl-β-D-glucopyranosyl) atractyligenin (2), together with one known compound. Their structures were established by comprehensive spectroscopic analysis coupled with single-crystal X-ray diffraction and electronic circular dichroism data. All compounds and their aglycone were evaluated for their anti-proliferative activities in vitro against three human cancer cell lines.

description: Résumé Depuis la loi sur l’accessibilité, la Langue des Signes Française (LSF) est inscrite comme langue d’enseignement et d’apprentissage. À la suite de cette reconnaissance, des diplômes de et en LSF ont été créés dont l’option facultative à l’examen du baccalauréat. Toutefois, malgré l’existence d’un Certificat d’Aptitude au Professorat de l’Enseignement du Second degré (CAPES) LSF et de cette option, les enseignants ont dû faire face à un manque de supports pédagogiques répondant à ces nouveaux cours. À la suite de ce constat, un groupe de pédagogues s’est réuni et a publié deux manuels pour l’enseignement de la LSF aux élèves entendants de niveaux A1 et A2. Le propos de notre article est de revenir brièvement sur les différents mouvements et actions qui ont permis à la LSF d’être visible et de décrire comment les séquences de ces deux manuels ont été construites, que ce soit du point de vue de la grammaire, du lexique et de l’interculturalité.

description: Nanometer circuits are becoming increasingly susceptible to soft-errors due to alpha-particle and atmospheric neutron strikes as device scaling reduces node capacitances and supply/threshold voltage scaling reduces noise margins. It is becoming crucial to add soft-error tolerance estimation and optimization to the design flow to handle the increasing susceptibility. The first part of this paper presents a tool for accurate soft-error tolerance analysis of nanometer circuits (ASERTA) that can be used to estimate the soft-error tolerance of nanometer circuits consisting of millions of gates. The tolerance estimates generated by the tool match SPICE generated estimates closely while taking orders of magnitude less computation time. The second part of the paper presents a tool for soft-error tolerance optimization of nanometer circuits (SERTOPT) using the tolerance estimates generated by ASERTA. The tool finds optimal sizes, channel lengths, supply voltages and threshold voltages to be assigned to gates in a combinational circuit such that the soft-error tolerance is increased while meeting the timing constraint. Experiments on ISCAS'85 benchmark circuits showed that soft-error rate of the optimized circuit decreased by as much as 47% with marginal increase in circuit delay.

description: Compact object mergers are promising candidates for the progenitor system of short gamma-ray bursts (GRBs). Using gravitational wave (GW) triggers to identify a merger, any electromagnetic (EM) counterparts from the jet can be used to constrain the dynamics and structure of short GRB jets. GW triggered searches could reveal a hidden population of optical transients associated with the short-lived jets from the merger object. If the population of merger-jets is dominated by low-Lorentz-factors, then a GW triggered search will reveal the on-axis orphan afterglows from these failed GRBs. By considering the EM counterparts from a jet, with or without the prompt GRB, the jet structure and dynamics can be constrained. By modelling the afterglow of various jet structures with viewing angle, we provide observable predictions for the on- and off- axis EM jet counterparts. The predictions provide an indication for the various features expected from the proposed jet structure models.

description: An analogue testing standard IEEE 1149.4 is mainly targeted for low-frequency testing. The problem studied in this paper is extending the standard also for radio frequency testing. IEEE 1149.4 compatible measurement structures (ABMs) developed in this study extract the information one is measuring from the radio frequency signal and represent the result as a DC voltage level. The ABMs presented in this paper are targeted for power and frequency measurements operating in frequencies from 1 GHz to 2 GHz. The power measurement error caused by temperature, supply voltage and process variations is roughly 2 dB and the frequency measurement error is 0.1 GHz, respectively.

description: Web users are shown an invalid certificate warning when their browser cannot validate the identity of the websites they are visiting. While these warnings often appear in benign situations, they can also signal a man-in-the-middle attack. We conducted a survey of over 400 Internet users to examine their reactions to and understanding of current SSL warnings. We then designed two new warnings using warnings science principles and lessons learned from the survey. We evaluated warnings used in three popular web browsers and our two warnings in a 100- participant, between-subjects laboratory study. Our warnings performed significantly better than existing warnings, but far too many participants exhibited dangerous behavior in all warning conditions. Our results suggest that, while warnings can be improved, a better approach may be to minimize the use of SSL warnings altogether by blocking users from making unsafe connections and eliminating warnings in benign situations.
La didactisation phonologique du texte littéraire dans des manuels utilisés pour l’enseignement/apprentissage du FLE en Grèce

description: Résumé Les manuels conçus selon les principes de l’Approche Actionnelle, actuellement utilisés pour l’enseignement du français langue étrangère en Grèce incluent de plus en plus dans leurs contenus les textes littéraires. L’état des lieux que nous avons fait au moyen de manuels représentatifs de cette approche didactique a révélé que la présence des textes littéraires varie en fonction du niveau et du public auxquels ils sont destinés et que parmi les compétences visées par leur exploitation, celle de la compétence phonologique est la moins développée sans toutefois être complètement exclue. Le genre du texte qui permet le développement implicite ou explicite de la compétence phonologique est la pièce de théâtre et le poème et leur nombre est très petit comparativement aux textes littéraires qui étudient les autres compétences langagières. Les activités phonologiques qui encadrent le texte littéraire invitent les élèves à travailler, la plupart du temps implicitement, sur la composante prosodique et aboutissent à une lecture expressive, suivie presque toujours par une activité de représentation théâtrale.

On the Empirical Importance of the Conditional Skewness Assumption in Modelling the Relationship Between Risk and Return
Creators: name: Pipien, Mateusz
Publisher: name: arXiv
Year: 2007
Subjects: subject: Applications (stat.AP)
subject: FOS: Computer and information sciences

description: The main goal of this paper is an application of Bayesian inference in testing the relation between risk and return on the financial instruments. On the basis of the Intertemporal CAPM model we built a general sampling model suitable in analysing such a relationship. The most important feature of our assumptions is that the skewness of the conditional distribution of returns is used as an alternative source of relation between risk and return. This general specification relates to GARCH-In-Mean model. In order to make conditional distribution of financial returns skewed we considered a constructive approach based on the inverse probability integral transformation. In particular, we apply the hidden truncation mechanism, two equivalent approaches of the inverse scale factors, order statistics concept, Beta and Bernstein distribution transformations, and also the constructive method. Based on the daily excess returns on the Warsaw Stock Exchange Index we checked the empirical importance of the conditional skewness assumption on the relation between risk and return on the Warsaw Stock Market. We present posterior probabilities of all competing specifications as well as the posterior analysis of positive sign of the tested relationship.

description: We study the behaviour of smooth solutions to the wave equation, $\square_gψ=0$, in the interior of a fixed Schwarzschild black hole. In particular, we obtain a full asymptotic expansion for all solutions towards $r=0$ and show that it is characterised by its first two leading terms, the principal logarithmic term and a bounded second order term. Moreover, we characterise an open set of initial data for which the corresponding solutions blow up logarithmically on the entirety of the singular hypersurface $\{r=0\}$. Our method is based on deriving weighted energy estimates in physical space and requires no symmetries of solutions. However, a key ingredient in our argument uses a precise analysis of the spherically symmetric part of the solution and a monotonicity property of spherically symmetric solutions in the interior.

description: Cooperative decentralized multirobot learning refers to the use of multiple learning entities to learn optimal solutions for an overall multirobot system. We demonstrate that traditional single-robot learning theory can be successfully used with multirobot systems, but only under certain conditions. The success and the effectiveness of single-robot learning algorithms in multirobot systems are potentially affected by various factors that we classify into two groups: the nature of the robots and the nature of the learning. Incorrect set-up of these factors may lead to undesirable results. In this paper, we systematically test the effect of varying five common factors (model of the value function, reward scope, delay of global information, diversity of robots’ capabilities, and number of robots) in decentralized multirobot learning experiments, first in simulation and then on real robots. The results show that three of these factors (model of the value function, reward scope, and delay of global information), if set up incorrectly, can prevent robots from learning optimal, cooperative solutions.

description: Ferula assa-foetida, containing organosulfides is widely used in Indian cuisine and traditionally claimed to have several medicinal properties including anticancer properties. Ferula oil enriched with organosulfides displayed significant inhibition of the cell growth in-vitro against SKOV3 and A549 cancer cells in a dose-dependent manner. This prompted us to investigate and delineate the compounds responsible for the activity. In this endeavor, the employed GC/GC-MS analysis resulted in the indecisive outcome. This led to the development of an expedient isocratic RP-HPLC method for the separation and purification of four major compounds which were further unambiguously characterised as (-)-E-2-butyl propenyl disulfide, (-)-Z-2-butyl propenyl disulfide, (-)-1-(methylthio)propyl(E)-1-propenyl disulfide, and (-)-1-(methylthio)propyl(Z)-1-propenyl disulfide employing 1H, 13C, and 2 D NMR. The isolated compounds were further evaluated for their potential against SKOV3 and A549 cell lines where a trisulfide has displayed better activity.

description: While most classical approaches to Granger causality detection assume linear dynamics, many interactions in real-world applications, like neuroscience and genomics, are inherently nonlinear. In these cases, using linear models may lead to inconsistent estimation of Granger causal interactions. We propose a class of nonlinear methods by applying structured multilayer perceptrons (MLPs) or recurrent neural networks (RNNs) combined with sparsity-inducing penalties on the weights. By encouraging specific sets of weights to be zero--in particular, through the use of convex group-lasso penalties--we can extract the Granger causal structure. To further contrast with traditional approaches, our framework naturally enables us to efficiently capture long-range dependencies between series either via our RNNs or through an automatic lag selection in the MLP. We show that our neural Granger causality methods outperform state-of-the-art nonlinear Granger causality methods on the DREAM3 challenge data. This data consists of nonlinear gene expression and regulation time courses with only a limited number of time points. The successes we show in this challenging dataset provide a powerful example of how deep learning can be useful in cases that go beyond prediction on large datasets. We likewise illustrate our methods in detecting nonlinear interactions in a human motion capture dataset.

We show how to optimize stage-resolution to minimize the power in a pipelined ADC. Exploration (via detailed synthesis) of several ADC configurations is used to show that a 4-3-2... resolution distribution uses the least power for a 13-bit 40 MSPS converter in a 0.25 $μ$m CMOS process.

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.

description: In this paper, we present an overview of the functionalities of the SOURCe Project, as it has evolved in a span of eight years after its creation in 2012. The SOURCe Project currently includes the search engine for the Searchable Online French-Greek Parallel Corpus for the University of Cyprus (SOURCe), the Pencil (an alignment tool), the Exercises, the Synonyms and the Library. The collection of corpora and tools are designed to be freely available as language processing resources for language and translation teachers and learners, but also for translators. Furthermore, we discuss how its applications can form an important part of effective learning resources. This paper focuses on the development and construction of the SOURCe Project, which is mainly based on a set of parallel corpora. The design, the content, and the availability of these corpora aim to serve the needs of teachers and students of French as a foreign language (other languages may be also added in the future) and also to facilitate future linguistic research. Our approach is a corpus linguistics one, undertaken from the perspective of language acquisition and translation studies.

description: This paper reports a novel simulation methodology for analysis and prediction of substrate noise impact on analog / RF circuits taking into account the role of the parasitic resistance of the on-chip interconnect in the impact mechanism. This methodology allows investigation of the role of the separate devices (also parasitic devices) in the analog / RF circuit in the overall impact. This way is revealed which devices have to be taken care of (shielding, topology change) to protect the circuit against substrate noise. The developed methodology is used to analyze impact of substrate noise on a 3 GHz LC-tank Voltage Controlled Oscillator (VCO) designed in a high-ohmic 0.18 $μ$m 1PM6 CMOS technology. For this VCO (in the investigated frequency range from DC to 15 MHz) impact is mainly caused by resistive coupling of noise from the substrate to the non-ideal on-chip ground interconnect, resulting in analog ground bounce and frequency modulation. Hence, the presented test-case reveals the important role of the on-chip interconnect in the phenomenon of substrate noise impact.

A local $ψ$-epistemic retrocausal hidden-variable model of Bell correlations with wavefunctions in physical space
Creators: name: Sen, Indrajit
Publisher: name: arXiv
Year: 2018
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We construct a local $ψ$-epistemic hidden-variable model of Bell correlations by a retrocausal adaptation of the originally superdeterministic model given by Brans. In our model, for a pair of particles the joint quantum state $|ψ_e(t)\rangle$ as determined by preparation is epistemic. The model also assigns to the pair of particles a factorisable joint quantum state $|ψ_o(t)\rangle$ which is different from the prepared quantum state $|ψ_e(t)\rangle$ and has an ontic status. The ontic state of a single particle consists of two parts. First, a single particle ontic quantum state $χ(\vec{x},t)|i\rangle$, where $χ(\vec{x},t)$ is a 3-space wavepacket and $|i\rangle$ is a spin eigenstate of the future measurement setting. Second, a particle position in 3-space $\vec{x}(t)$, which evolves via a de Broglie-Bohm type guidance equation with the 3-space wavepacket $χ(\vec{x},t)$ acting as a local pilot wave. The joint ontic quantum state $|ψ_o(t)\rangle$ fixes the measurement outcomes deterministically whereas the prepared quantum state $|ψ_e(t)\rangle$ determines the distribution of the $|ψ_o(t)\rangle$'s over an ensemble. Both $|ψ_o(t)\rangle$ and $|ψ_e(t)\rangle$ evolve via the Schrodinger equation. Our model exactly reproduces the Bell correlations for any pair of measurement settings. We also consider `non-equilibrium' extensions of the model with an arbitrary distribution of hidden variables. We show that, in non-equilibrium, the model generally violates no-signalling constraints while remaining local with respect to both ontology and interaction between particles. We argue that our model shares some structural similarities with the modal class of interpretations of quantum mechanics.

description: The Centre for the Greek Language (CGL) has designed the Modern Greek Language e-Diagnostic tests (MOGEDs). MOGEDs are online testing applications, available for teachers of Modern Greek as a second or foreign language (L2). They are mainly addressed to adult potential candidates for CGL’s language exams, willing to assess their language competence level. MOGEDs are compliant with the standard levels (A1-C2) of the Common European Framework of Reference for Languages (CEFR) (Council of Europe 2001) as adapted for Modern Greek. In this paper, the structure of MOGEDs will be analysed and compared to equivalent e-diagnostic tests in terms of the technical architecture adopted. MOGEDs have been developed within the framework of educational technology, taking into account (a) the CGL’s technical expertise in that field in relation with (b) state-of-the-art content design principles and (c) current trends in Information and Communication Technology.

description: The effectiveness of multirobot learning in achieving optimal, cooperative solutions is potentially affected by various factors having to do with the nature and configuration of the robots and the nature of the learning entities. Varying one factor wrongly may lead to undesirable results. There is no reported work on how systematically to set up these factors. In this paper, we methodically test the effect of varying four common factors (reward scope, global information delay, diversity of robots, and number of robots) in a decentralized multirobot system, first in simulation and then on real robots. The results show that two of these factors, reward scope and global information delay, if set up incorrectly, can prevent optimal, cooperative solutions.

description: With the advantages of unicellular eukaryotic structure and easy manipulation, yeast becomes a popular tool for biochemical, genetic and medicinal studies. In order to construct an efficient anti-inflammatory drug screening platform, we engineered yeast as a double-molecule carrier, of which an inserted domain (I domain) of lymphocyte function-associated antigen 1 was displayed on yeast surface and a green fluorescent protein (GFP) was expressed inside cytosol. The I domain specifically targeted a surface marker of mammalian cells, intercellular adhesion molecule 1, whose number is correlated with the level of cellular inflammation. Examination of GFP intensity enables swift quantification of the yeast-mammalian cell binding and thus it reflects inflammatory potency, herein the inflammatory index, of a chemical imposed to cells. The inflammatory potency of a total of 1340 chemicals was indexed. Among them, 1 inflammation-inducing and 1 inflammation-reducing compounds were verified both in vitro and in vivo. Our method demonstrated a swift, facile and high-throughput screening platform at the protein level for inflammation and related diseases drug discovery without using sophisticated instruments.

description: We show that states on tensor products of matrix algebras whose ranks are relatively small are {\em almost surely} entangled, but that states of maximum rank are not. More precisely, let $M=M_m(\mathbb C)$ and $N=M_n(\mathbb C)$ be full matrix algebras with $m\geq n$, fix an arbitrary state $ω$ of $N$, and let $E(ω)$ be the set of all states of $M\otimes N$ that extend $ω$. The space $E(ω)$ contains states of rank $r$ for every $r=1,2,...,m\cdot\rankω$, and it has a filtration into compact subspaces $$ E^1(ω)\subseteq E^2(ω)\subseteq ...\subseteq E^{m\cdot\rankω}=E(ω), $$ where $E^r(ω)$ is the set of all states of $E(ω)$ having rank $\leq r$. We show first that for every $r$, there is a real-analytic manifold $V^r$, homogeneous under a transitive action of a compact group $G^r$, which parameterizes $E^r(ω)$. The unique $G^r$-invariant probability measure on $V^r$ promotes to a probability measure $P^{r,ω}$ on $E^r(ω)$, and $P^{r,ω}$ assigns probability 1 to states of rank $r$. The resulting probability space $(E^r(ω),P^{r,ω})$ represents ``choosing a rank $r$ extension of $ω$ at random". Main result: For every $r=1,2,...,[\rank ω/2]$, states of $(E^r(ω),P^{r,ω})$ are almost surely entangled.

description: The Online Greek Course (OGC) is an e-learning environment for Modern Greek as a second/foreign language for adults in Greece or abroad. It is hosted in the Learning Management System of the Aristotle University of Thessaloniki and was awarded the “European Language Label 2016”. The OGC is an exclusively online course which combines synchronous and asynchronous learning. This article presents the combination of technological tools used in OGC to serve its learning objectives. The OGC employs tools of both tutorial CALL (learning objects) and Computer Mediated Communication (CMC, namely, students’ forum, wiki and web conferencing) in a language learning program, which aims at developing both the receptive and productive skills for levels A1 and A2. Using CMC tools in order to integrate oral tasks for the virtual classroom and writing tasks for the students’ forum is the key feature of OGC.

description: Résumé La recherche qui est présentée dans l’article porte sur les résultats d’une étude menée auprès d’apprenants hellénophones du français langue étrangère (FLE) dont le but a été d’explorer le potentiel des stratégies de lecture pour le développement de la compréhension écrite et, plus particulièrement, de la compréhension des expressions figées verbales de la langue française. Après avoir délimité notre étude, nous esquissons brièvement le fondement théorique sur lequel se base notre recherche. Par la suite, nous nous concentrons sur la méthodologie de notre recherche et, enfin, nous présentons l’analyse des résultats obtenus. Notre recherche a démontré qu’il est important de faire émerger la conscience chez les apprenants envers la présence du figement dans le discours, les variétés structurelles, les propriétés et les caractéristiques qui lui sont propres par rapport aux combinaisons libres. L’utilité des stratégies de lecture a été également démontrée dans nombreux cas. Les résultats de notre recherche révèlent que, au moyen de différentes stratégies, les apprenants d’une langue étrangère seraient capables de réussir l’interprétation et réinsertion des expressions figées dans des contextes pertinents.

description: Cost and efficiency concerns can force distributed embedded systems to use a single network for both critical and non-critical messages. Such designs must protect against masquerading faults caused by defects in and failures of non-critical network processes. Cyclic Redundancy Codes (CRCs) offer protection against random bit errors caused by environmental interference and some hardware faults, but typically do not defend against most design defects. A way to protect against such arbitrary, non-malicious faults is to make critical messages cryptographically secure. An alternative to expensive, full-strength cryptographic security is the use of lightweight digital signatures based on CRCs for critical processes. Both symmetric and asymmetric key digital signatures based on CRCs form parts of the cost/performance tradeoff space to improve critical message integrity.

description: To visualize the topography of thin oxide films during growth, thereby enabling to study its growth behavior quasi real-time, we have designed and integrated an atomic force microscope (AFM) in a pulsed laser deposition (PLD) vacuum setup. The AFM scanner and PLD target are integrated in a single support frame, combined with a fast sample transfer method, such that in-situ microscopy can be utilized after subsequent deposition pulses. The in-situ microscope can be operated from room temperature (RT) up to 700$^\circ$C and at (process) pressures ranging from the vacuum base pressure of 10$^{-6}$ mbar up to 1 mbar, typical PLD conditions for the growth of oxide films. The performance of this instrument is demonstrated by resolving unit cell height surface steps and surface topography under typical oxide PLD growth conditions.

The contribution of lexical variables to the measurement of Italian texts’ readability level

Publisher: name: Journal of Applied Linguistics

description: The present study aims to reveal the contribution of type/token and content word/token ratio to the difficulty level calculation of Italian texts. In the text readability analysis, these lexical traits of a text are often used in combination with other linguistic (e.g. syntactic structure of the text) and quantity criteria, (e.g. word number), without providing a clear indication of their weight to the final readability score. For this purpose, we used the readability formulas Gulpease and Read-It, (Dell’Orletta, Montemagni and Venturi 2011) to analyze a corpus of 184 Italian texts, that have been used for the examination of reading comprehension by the National Language Certification System of Greece (KPG), from 2011 to 2017. The results showed a strong correlation of the type/token and content word/token variables with the difficulty level of the analyzed texts and a higher contribution of the lexical group to the final score, in comparison with the word frequency variable.

description: A Cyclic Redundancy Code (CRC), when used properly, can be an effective and relatively inexpensive method to detect data corruption across communication channels. However, some systems use CRCs in ways that violate common assumptions made in analyzing CRC effectiveness, resulting in an overly optimistic prediction of system dependability. CRCs detect errors with some finite probability, which depends on factors including the strength of the particular code used, the bit-error rate, and the message length being checked. Common assumptions also include a passive network inter-stage, explicit data words, memoryless channels, and random independent symbol errors. In this paper we identify some examples of CRC usage that compromise ultra-dependable system design goals, and recommend alternate ways to improve system dependability via architectural approaches rather than error detection coding approaches.

description: As a relatively young discipline within software engineering, value-based software engineering does not yet have an established curriculum. The area draws on models and techniques in so many other disciplines that it is likely to be some time before a single individual is ready to prepare a course or a textbook. Several of the EDSER-4 participants expressed interest and enthusiasm for sharing the effort of developing curriculum and course materials. Inspired by the success of open source software development, especially the distributed collaboration, the free public access to the results, and the lack of administrative overhead; we decided to try to establish a similar community for curriculum development. This report describes progress to date, with emphasis on the community standards for cooperation and sharing.
