Software support for parallel processing of irregular and dynamic computations
Creators: name: Jiao, Jia
Publisher: name: Rutgers University
Year: 1996

description: Many real world scientific computing problems are irregular and dynamic, which pose great challenge to the effort of parallelization. In this thesis, we study the efficient mapping of a subclass of these problems, namely the "Stepwise slowly changing" irregular computations, onto distributed memory multiprocessors using the task graph scheduling approach. There exists a large class of applications which belong to this category. Intuitively, the irregularity requires sophisticated mapping algorithms, and the "slowness" in the changes of the computational structures between steps allows the scheduling cost to be amortized, justifying the approach. We study three representative and widely-used applications in this thesis:The N-body simulation in particle physics, the Vortex-Sheet Roll-Up and the Contour Dynamics Computation from Computational Fluid Dynamics. We start with an initial global compile-time scheduling using PYRROS, and as this schedule degenerates over the iterative process, we apply new rescheduling algorithms to improve performance. We develop rescheduling algorithms for two important dynamic patterns: task graph weight variation, and dynamic spawning of new subgraphs. These algorithms are implemented and tested on irregular applications such as the N-body and Vortex-Sheet. Our experiments show that global scheduling using sophisticated methods can be beneficial for these problems, and our fast rescheduling algorithms can correct run-time imbalance with very low cost. In summary, we introduce two new rescheduling heuristics and discuss several central issues such as schedule reuse, performance/scheduling overhead trade-off and the guidelines for choosing an appropriate rescheduling method. We identify classes of problems where rescheduling algorithms are applicable, and finally present experimental evidence to justify our approach. Throughout the thesis, performance results are obtained from particular problems but presented in the general framework of software supporting systems. In addition, we examine an automatic task graph generation tool that can handle restricted cases of sequential code, and carry out its integration with PYRROS system. The new system is capable of realizing automatic parallelization of simple programs, a step forward to the grand challenge of fully automatic parallelization of regular and irregular code.

description: The global politics of the climate emergency entails complex choices concerning the distribution of costs and benefits between countries, within countries and across society. The distributional debate between countries is well-established at the international level after three decades of United Nations negotiations. At the domestic level, individual countries have had to make challenging choices as they consider transitioning to low carbon energy systems. While the distributional struggle within countries is less explicitly addressed at the international level, it is beginning to shape climate global politics as climate policy shifts from the environmental margins to the economic core of government decision-making. © Royal Irish Academy
Scaling up Action Schools! BC: How Does Voltage Drop at Scale Affect Student Level Outcomes? A Cluster Randomized Controlled Trial

description: Action Schools! BC (AS! BC) was scaled-up from an efficacy trial to province-wide delivery across 11 years (2004–2015). In this study we: (1) describe strategies that supported implementation and scale-up; (2) evaluate implementation (teachers’ physical activity (PA) delivery) and student’s PA and cardiorespiratory fitness (CRF) within a cluster randomized controlled trial during years 2 and 3 of scale-up; and (3) assess relationships between teacher-level implementation and student-level outcomes. We classified implementation strategies as process, capacity-building or scale-up strategies. Elementary schools (n = 30) were randomized to intervention (INT; 16 schools; 747 students) or usual practice (UP; 14 schools; 782 students). We measured teachers’ PA delivery (n = 179) using weekly logs; students’ PA by questionnaire (n = 30 schools) and accelerometry (n = 9 schools); and students’ CRF by 20-m shuttle run (n = 25 schools). INT teachers delivered more PA than UP teachers in year 1 (+33.8 min/week, 95% CI 12.7, 54.9) but not year 2 (+18.8 min/week, 95% CI −0.8, 38.3). Unadjusted change in CRF was 36% and 27% higher in INT girls and boys, respectively, compared with their UP peers (year 1; effect size 0.28–0.48). Total PA delivered was associated with change in children’s self-reported MVPA (year 1; r = 0.17, p = 0.02). Despite the ‘voltage drop’, scaling-up school-based PA models is feasible and may enhance children’s health. Stakeholders must conceive of new ways to effectively sustain scaled-up health promoting interventions if we are to improve the health of students at a population level.

 Remarks. – Unlike other coral genera, the center of diversity of Stylophora is in the western Indian Ocean and the Red Sea (Veron, 1995) and not in the Indo-West Pacific. S. kuehlmanni and S. danae, both described here, have been recorded from the Red Sea (Scheer & Pillai, 1983). Nemenzo (1964, 1986) described S. danae from Puerto Galera, Oriental Mindoro in western Philippines but the species is not reflected in Veron & Hodgson (1989) nor in Veron & Fenner (2000), hence this report.

Some comments on the decision approach to statistical inference

Year: 2013

description: The decision approach to statistical inference is discussed from the point of view of the aptitude of its underlying principles to be useful in the real problem solving area. Conditional and non conditional statistical decision inference are also discussed. Moreover a set of inferential problems for which the decision approach fails are examined. So that if a statistician wants to solve them he needs to have at his disposal a set of different inferential approaches, based on different underlying principles and/or axioms, useful in different situations and for different tasks. Therefore, in a complex problem, he could need many approaches at the same time, especially if this problem can be put into a set of inferential subproblems.

 Remarks. – The genus Acropora is the largest genus of stony corals with 113 species in Wallace, 1999 and 170 species in Veron, 2000. Of Wallace’s 113, 73 species are found in southeast Asia. Only 13 species are found to be endemic to certain areas of the Indo-Pacific while the rest are widespread from the Atlantic to the Pacific Ocean (Wallace, 1999). However, the central Indo-Pacific region has the highest diversity of Acropora mainly brought about by the continuing range expansion of the species from both the Indian and Pacific oceans (Wallace, 1999). Acropra halmaherae was classified by Wallace (1999) under the Acropora horrida group along with seven other species that are usually found in subtidal sheltered habitats.

description: This work is strictly connected to the same authors', appeared in the 4th issue of "STATISTICA", 1984. Following Gini's conception, that divides the concordance indexes into homophile indexes and correlation indexes, accordingly we should make a reference to the relative maximum knowledge or to the concordance absolute maximum one, we have discussed on these pages about a general theory of the correlation square indexes among deviations, and so meaning that indexes having logical structure of partial correlation indexes have been introduced. It goes without saying that in the context the simple correlation square index among deviations proposed by Gini occurs again.

Fitting the Lorenz curve
Creators: name: Tarsitano, A.
Publisher: name: Dep. of Statistical Sciences "Paolo Fortunati", Università di Bologna
Year: 2013

description: The Lorenz curve is a graph relating the cumulative proportion of income receiving units to the cumulative proportions of incomes in the ascending order.
Usually the Lorenz curve is derived from the income density function. In this note the curve is studied in the context of fitting equations to data.
After discussing the general formalism of a Lorenz curve, a generalization of the Lorenz curve associated with the Pareto model is introduced. The new functional form provided a basis to compute several indices of concentration and asymmetry. In addition, fitting and estimation procedure for the parameters of the curve were proposed. Finally, the suggested model was applied to investigate the relationship between economic growth and income distribution.

Binomial data in presence of overdispersion

description: In many applications of binomial data independent observations in different groups can have positive correlation within groups so that the variance is larger than under independence (overdispersion) Amongst the various models that can be fitted to deal with the phenomenon of over-dispersion, the use of quasi-likelihood functions is now days a well established one. In this paper we consider a method for the estimate of the dispersion parameter based on a procedure proposed by Williams (1982) that can be applied to the case of grouped data. As an application, a set of data on an experiment to examine the infestation caused by an insect on the olive tree is analysed.

Using TLB Speculation to Overcome Page Splintering in Virtual Machines

Publisher: name: Rutgers University

description: As systems provide increasing memory capacities to support memory-intensive workloads, Translation Lookaside Buffers (TLBs) are becoming a critical performance bottleneck. TLB performance is exacerbated with virtualization, which is typically implemented with two-dimensional nested page tables. While virtualization vendors recommend using large pages to mitigate TLB overheads, in practice, page splintering (where the guest utilizes large pages, only to be broken by the hypervisor, or vice-versa) is prevalent and severely restricts large page benefits. We characterize real-system page allocation behavior under virtualization and find that the guest operating system (OS) often aggressively allocates large pages, which are then broken by the hypervisor to baseline pages. However, in trying to allocate large pages, the hypervisor usually allocates these baseline system physical pages in aligned, contiguous frames with respect to the application’s guest virtual address. In response, we propose hardware to, on TLB misses, speculate on the system physical address based on the application’s virtual address. TLB speculation can be readily overlaid on various TLB organizations and is effective under a wide range of real-world virtual machine deployments. Overall, TLB speculation eliminates almost all of the TLB handling overheads of virtualization.

description: Bone healing is a complex, well-organized process. Multiple factors regulate this process, including growth factors, hormones, cytokines, mechanical stimulation, and aging. One of the most important signaling pathways that affect bone healing is the Notch signaling pathway. It has a significant role in controlling the differentiation of bone mesenchymal stem cells and forming new bone. Interventions to enhance the healing of critical-sized bone defects are of great importance, and stem cell transplantations are eminent candidates for treating such defects. Understanding how Notch signaling impacts pluripotent stem cell differentiation can significantly enhance osteogenesis and improve the overall healing process upon transplantation. In Rancourt’s lab, mouse embryonic stem cells (ESC) have been successfully differentiated to the osteogenic cell lineage. This study investigates the role of Notch signaling inhibition in the osteogenic differentiation of mouse embryonic and induced pluripotent stem cells (iPS). Our data showed that Notch inhibition greatly enhanced the differentiation of both mouse embryonic and induced pluripotent stem cells.

description: Il processo di abduzione è qui dettagliatamente analizzato, sia relativamente alla sua strurtura, sia alla funzione svolta dagli elementi che formano la struttura stessa. Detta analisi viene compiuta finalizzandola all'argomento nel quale questo articolo si colloca: ottenimento di un modello del processo in argomento, da utilizzare in Intelligenza Artificiale. L'approccio seguito considera il modello classico del processo stesso, cioè quello probabilistico dovuto a Bayes. In tal modo può essere ottenuta una ideale trama sulla quale tessere inferenze abduttive. Lo scopo che in definitiva è perseguito è quello di pervenire ad un modello di apprendimento di natura abduttiva basato su dati probabilistici. Questo verrà attuato alimentando la struttura ottenuta con funzione di appartenenza computabili, anzichè con funzioni di probabilità.

description: In questo lavoro si considera il problema dell'analisi dei fenomeni dinamici non lineari e in particolare dei comportamenti oscillatori, non costretti ad andamenti sinusoidali. Nella classe dei processi a parametro discreto, si propone un modello a due stati per rappresentare il carattere di eterogeneità di struttura della serie storica. La dinamica tra gli stati viene quindi descritta da un processo semi-markoviano, le cui probabilità di transizione vengono formulate su un insieme di osservabili, che si identificano nei "tempi di soggiorno" negli stati e nei valori di soglia della serie. Il cambiamento viene perciò rappresentato da funzioni d'azzardo generalizzate e definite su un insieme di covariate. Infine, I'aspetto predittivo viene sviluppato in ambito bayesiano e nella struttura risultante si deriva, in condizioni particolari, il modello STAR proposto da Tong.

description: In economies that are dependent on fossil fuel revenues, Realization of long-term plans, mid-term and annual budgeting requires a fairly accurate estimation of the amount of consumption and its price fluctuations. Accordingly, the present study is using machine learning techniques to predict the usage of fossil fuels (Diesel, Black oil, Heating oil, and Petrol) in mid-term. Exponential Smoothing, a model of time series and the Neural Network model have been applied on the actual usage data obtained from Shahroud area from 2010 to 2015. For estimation of predictive value by Neural Network method, the training and testing samples, the highest and lowest errors with a range of 41%-0.89% and 88%-3% for the Mean Absolute Percent Deviation are the most appropriate predictions for Petrol consumption. And in the Single Exponential Smoothing, the forecast rate for each product is estimated on a quarterly as well as monthly basis.

Uterine perforation

description: Exaggerated placental site (EPS) is usually an incidental finding seen in curettings after an abortion. Placenta increta is, by definition, a disease that damages and destroys myometrium; but prior literature has not paid sufficient attention to the role of myometrium in its pathogenesis and diagnosis. We present an unusual case of placenta increta in a hysterectomy performed for uterine perforation after curettage for termination of pregnancy at 18 weeks. The initial histologic section of the implantation site suggested EPS. Actin stains showed degenerated inflamed muscle at the EPS-like site, keratin stains showed interstitial trophoblast in the zone of myometrial damage, and the wall of the corpus was grossly thinned under the placenta. The myometrial damage may have softened the wall, predisposing to uterine perforation by the curettage procedure.

Year: 2013

description: We developed a procedure to find change-points which seems both widely applicable and easy to implement on computer. The number of regimes is not needed a priori. Monte Carlo simulations showed that it is efficient also at low sample size. The approach is fully nonparametric and can be applied without knowing the statistical distribution of each subset. Confidence intervals are evaluated by a Monte Carlo simulation and this requires the latter distributions to be given explicitly. These are determined by Kolumogorov-Smirnov one sample goodness-of-fit test applied to all the different sets identified in the change-point analysis. The procedure is presented with a practical application to Gaussian and Poisson series.

description: The maximum-entropy principle has recently been discussed in this journal by R.Rosa. The present note stresses a few points made or touched upon there. First it is shown how to derive, by means of the principle under discussion, the quantal statistics, along with the intermediate ones. Then the points is made that the correct application of the principle and its ultimate acceptance by the scientific community require that one use an appropriate representation for the entropy. Thus great importance is attributed to the characterizations of the various entropies.

description: Nell'analisi delle serie temporali si definisce la funzione di autocorrelazione inversa che ha varie applicazioni nella identificazione di modelli lineari univariati e bivariati e in problemi d' interpolazione.
La stima delle autocorrelazioni inverse viene effettuata con due diversi metodi, il primo basato sulla stima della densità spettrale, l'altro basato sull'adattamento alla serie di un processo autoregressivo di ordine elevato. In ambedue i casi i risultati dipendono dalla scelta di un valore di troncamento o di "ampiezza" della stima; valori diversi del punto di troncamento possono produrre risultati anche molto differenti. Pertanto appare opportuno esaminare le stime per vari valori di ampiezza. A questo fine si propongono qui due diverse procedure ricorsive che permettono di stimare le autocovarianze e autocorrelazioni inverse per valori crescenti del punto di troncamento, mediante formule ricorsive la prima si basa sul metodo autoregressivo per la stima delle autocovarianze inverse, l'altra su un nuovo metodo di stima derivato dalla proprietà di ortogonalità tra autocovarianze ordinarie e inverse.

Limited-size logging for fault-tolerant distributed shared memory with independent checkpointing

Publisher: name: Rutgers University

description: This paper presents a fault tolerance algorithm for a home-based lazy release consistency distributed shared memory (DSM) system based on volatile logging and independent checkpointing. The proposed approach targets large-scale distributed shared-memory computing on local-area clusters of computers as well as collaborative shared-memory applications on wide-area meta-clusters over the Internet. The challenge in building such systems lies in controlling the size of the logs and to garbage collect the unnecessary checkpoints in the absence of global coordination. In this paper we define a set of rules for lazy log trimming (LLT) and checkpoint garbage collection (CGC) and prove that they do not affect the recoverability of the system. We have implemented our logging algorithm in a home-based DSM system and showed on three representative applications that our scheme effectively bounds the size of the logs and the number of checkpointed page versions kept in stable storage.

Ein zentrales Ergebnis dieser Studie war, dass "die Herstellung von grafischen Papieren aus Recyclingfasern wesentlich umweltfreundlicher ist als die Verwendung von Frischfasern aus Holz als Rohstoff". Die Vergabekriterien des Umweltzeichens Blauer Engel für Papierprodukte basieren ebenfalls auf den Ergebnissen dieser Studie und fordern die höchstmögliche Verwendung von Recyclingpapier, vorzugsweise aus Post-Consumer-Abfällen, als Rohstoff für die Papierherstellung. Die vorliegende Studie stellt eine Aktualisierung dieser Ökobilanz dar. Dabei wurde sie um die Betrachtung von Hygienepapieren, und eine Diskussion über Biodiversität, Landnutzungswandel und Kohlenstoffspeicherung ergänzt. Besonderer Fokus liegt zudem auf dem Papierrecycling in Deutschland. Die aktualisierten Ergebnisse stützen weitgehend die bisherigen Empfehlungen des UBA und die Anforderungen des Ökolabels Blauer Engel zur Förderung von Recyclingpapier. Es ist wesentlich umweltfreundlicher, grafisches Papier aus recycelten Fasern herzustellen, als Primärfasern aus Holz als Rohstoff zu verwenden. Quelle: Forschungsbericht
description: The last life-cycle assessment of the German Environment Agency for graphic papers, in which the environmental impacts of virgin papers and recycled papers were comprehensively examined, dates from the year 2000 (Tiedemann et al. 2000). A key finding of this study was that "it is much more environmentally friendly to produce graphic papers from recycled fibres than to use virgin fibres from wood as a raw material". The award criteria of the Blauer Engel (Blue Angel) eco-label for paper products are also based on the results of this study and demand the highest possible use of recycled paper, preferably from post-consumer waste, as raw material for paper production. The present study is an update of this LCA. It has been extended to include the consideration of tissue papers and a discussion on biodiversity, land use change and carbon capture in forests. A special focus is also placed on paper recycling in Germany. The updated results largely support the previous UBA recommendations and the requirements of the Blue Angel eco-label for the promotion of recycled paper. It is much more environmentally friendly to produce graphic paper from recycled fibres than to use virgin fibres from wood as raw material. Quelle: Forschungsbericht

description: It is typically expected that when people work together, they can often accomplish goals that are difficult or even impossible for individuals. We consider this notion of the group achieving more than the sum of all individuals' achievements to be the synergic effect in collaboration. Similar expectation exists for people working in collaboration for information seeking tasks. We, however, lack a methodology and appropriate evaluation metrics for studying and measuring the synergic effect. In this paper we demonstrate how to evaluate this effect and discuss what it means to various collaborative information seeking (CIS) situations. We present a user study with four different conditions: single user, pair of users at the same computer, pair of users at different computers and co-located, and pair of users remotely located. Each of these individuals or pairs was given the same task of information seeking and usage for the same amount of time. We then combined the outputs of single independent users to form artificial pairs, and compared against the real pairs. Not surprisingly, participants using different computers (co-located or remotely located) were able to cover more information sources than those using a single computer (single user or a pair). But more interestingly, we found that real pairs with their own computers (co-located or remotely located) were able to cover more unique and useful information than that of the artificially created pairs. This indicates that those working in collaboration achieved something greater and better than what could be achieved by adding independent users, thus, demonstrating the synergic effect. Remotely located real teams were also able to formulate a wider range of queries than those pairs that were co-located or artificially created. This shows that the collaborators working remotely were able to achieve synergy while still being able to think and work independently. Through the experiments and measurements presented here, we have also contributed a unique methodology and an evaluation metric for CIS.

description: High supercooling and single functionalization are the main barriers to the large-scale application of microencapsulated phase-change materials (PCMs) in the construction industry. To address these issues, we propose a new inorganic microencapsulated PCM, PW@CaWO4, which was synthesized via the in situ polymerization method using inorganic CaWO4 as shell and phase-change paraffin wax (PW) as core. We investigated the effects of different emulsifiers and core-to-shell ratios on microcapsule properties and found that the PW@CaWO4 microcapsules have regular spherical topography and good uniformity in particle size. During the synthesis process, the CaWO4 shell provides convenient conditions for heterogeneous nucleation of PW and effectively reduces the supercooling degree. The minimum supercooling degree of the PW@CaWO4 microcapsules is only 1.00 ± 0.08 °C, which is 3.41 °C lower than that of PW. Moreover, the PW@CaWO4 microcapsules can absorb ultraviolet radiation and exhibit fluorescence, which originates from the peculiar WO42– structure in the CaWO4 shell, eliminating the need for doping other light-activating ions into the shell. The newly prepared microcapsules possess several advantages, including suitable particle size, low supercooling, good heat storage, high thermal conductivity, good short-wave ultraviolet absorption, peculiar fluorescence, excellent proof of leakage, and so on. The microcapsules can be applied to fluorescent architectural energy-saving coatings.
An asymptotically model free method in statistical analysis of spatial point patterns

description: In making inference on Spatial Point Processes often there it is the problem of knowing (or estimating) the distribution of relevant statistics. In the present paper it is proposed a method for estimating the distribution function of any strongly convergent statistic in a large class of Spatial Point Processes.
The method is based on conditional simulation and doesn't depend on process' distribution.
Asymptotically the statistics generated by this method of "autosimulation" have the same distribution as those generated by Montecarlo methods when the probability structure of the Process is completely known.

On the estimation of the geometric distribution parameter in seismology

Year: 2013

description: L'articolo affronta il problema della stima del parametro p della distribuzione geometrica e dei relativi intervalli di confidenza. L'argomento è di notevole importanza in sismologia perchè si è trovato che la magnitudo dei terremoti segue una distribuzione esponenziale (la ben nota legge di Gutenberg-Richter) e perciò, a seguito del raggruppamento dei dati in classi di ampiezza finita, ci si attende che i campioni sperimentali si adattino alla distribuzione geometrica. Per motivi di completezza, diamo un rapido cenno dei metodi per la stima "puntuale" del parametro p. Obiettivo principale dell'articolo è tuttavia la determinazione degli intervalli di confidenza relativi a p.
Un'analisi accurata ci consente di discutere e confrontare soluzioni esatte e soluzioni asintotiche. Sotto forma di tabelle vengono presentati gli intervalli di confidenza calcolati per i valori standard del coefficiente di confidenza. Le tabelle sono intese come un utile strumento di lavoro, in quanto bastano gli elementari procedimenti algebrici di interpolazione e di estrapolazione per calcolare anche ogni soluzione non esplicitamente compresa nelle tavole.

Some methodological problems of biodemographic investigations. A sampling research on menopausal age
Creators: name: Monari, P.

description: The study of menopausal age is nowadays of great interest for anthropologists and biodemographers since, together with the menarche age, it defines the duration of the fertile period of a female population. The two methods of analysis most used for such researches are compared in this work the longitudinal (retrospective) method and the transversal ("status quo") method. The two criteria are deeply different both for methodological characteristics and research aims; they are therefore not interchangeable. The former describes an historically ended situation and estimates the probability that a woman will reach such condition at age x. The latter considers the phenomenon from the viewpoint of its composite actuality and estimates the probability that a woman of age x is undergoing menopause. The different numerical results obtained by applying the two methods to the data of the same women sample are compared and discussed in this research.

CHARACTERIZING THE EFFECT OF CRISPR/CAS9 ON BASE EXCISION REPAIR

description: While genetic material is relatively stable it is mutable and accumulates DNA damage from many endogenous and exogenous sources. DNA repair pathways are required to remove that damage and prevent genome instability resulting from unrepaired damage. Importantly, mutations generated following the repair of damage induced by CRISPR/Cas9 is critical for traditional genome editing approaches. However, many CRISPR-based technologies rely on catalytically dead Cas9 (dCas9) which only binds DNA. Given that binding alone can be mutagenic, the work presented in this dissertation focuses on further understanding the mechanisms in which binding alone induces mutations. We first examined whether the targeting of dCas9 inhibits the repair of uracil and inosine base lesions through base excision repair (BER) in vitro. This led to the discovery that dCas9 is inhibitory to multiple classes of DNA glycosylases in vitro, likely through steric occlusion (i.e., preventing access to lesions). Moreover, our data implies that the mechanisms DNA glycosylases employ to bind and remove damaged DNA likely impact how dCas9 impairs their activity. We also addressed whether inhibition of repair occurs in cells by investigating how exposure to endogenous mutagen like methylmethanesulfonate (MMS) impact dCas9-associated mutagenesis in the yeast Saccharomyces cerevisiae. Interestingly, we saw that in cells expressing both dCas9 and guideRNAs targeting the CAN1 gene in yeast, MMS exposure significantly increased both mutation frequencies and rates in repair-proficient cells. We speculate that there could be multiple mechanisms driving this mutagenesis and that persistent binding by Cas9 (or dCas9) likely promotes background mutations arising during genome editing.
