Is an alligator better than an armadillo? [interconnection networks]

Multiprocessor interconnection network effectiveness differs considerably across applications and operating environments, but even if these variables were fixed, cost and performance metrics must be chosen. Scientifically determining the best network is as difficult as saying with certainty that one animal is better than another. We explore the problems of determining which metrics or weighted set of metrics designers should use to compare networks and how they should apply these metrics to yield meaningful information. We also look at problems in conducting fair and scientific evaluations.
Multiple Shape Correspondence by Dynamic Programming

We present a multiple shape correspondence method based on dynamic programming, that computes consistent bijective maps between all shape pairs in a given collection of initially unmatched shapes. As a fundamental distinction from previous work, our method aims to explicitly minimize the overall distortion, i.e., the average isometric distortion of the resulting maps over all shape pairs. We cast the problem as optimal path finding on a graph structure where vertices are maps between shape extremities. We exploit as much context information as possible using a dynamic programming based algorithm to approximate the optimal solution. Our method generates coarse multiple correspondences between shape extremities, as well as denser correspondences as by‐product. We assess the performance on various mesh sequences of (nearly) isometric shapes. Our experiments show that, for isometric shape collections with non‐uniform triangulation and noise, our method can compute relatively dense correspondences reasonably fast and outperform state of the art in terms of accuracy.
Peculiarities of Vascular Component of Communicative Systems in Rectal Adenomas

Background: Adenomas are assumed to be the precursors of colorectal cancer. Aim was to study the epithelial and stromal components of various histological types of rectal adenomas. For evaluation of condition of all the components of neoplasia we have introduced a term “communicative systems” which consists of microcirculatory vessels and vegetative nerve terminals and the cell populations surrounding these two components. Materials and Methods: A study of surgical and biopsy materials of tubular (TA), tubulovillous (TVA) and villous (VA) rectal adenomas — 30 cases of each histological type was performed. 20 biopsies of rectal mucosa were studied as a control group. The material was microscopically examined using Hematoxylin and Eosin, Picrofuchsin by van Gieson and immunohistochemical stains (Ki-67, CD31). Micromorphometric study was performed and nonparametric methods (U-Test, Kruskal-Wallis test) were used. Correlations were calculated using Spearman rank correlation coefficients. Probability values < 0.05 were considered significant. Results: Index of proliferative activity of epithelial cells according to expression of Ki-67 in the control group comprised of 20.9±0.7, 26.6±0.3 in TA, 36.8±1.3 in TVA, 47.1±1.7 in VA. The reliable significant differences (p < 0.05) in proliferative activity of epithelial cells in the following adjacent pairs of tumors were revealed: TA–TVA, TVA–VA. Area of vascular bed was characterized by following indices: 30.7±0.9 in control group, 41.1±1.1 in TA, 82.2±1.3 in TVA, 274.3±7.3 in VA. The reliable significant differences (p < 0.05) in the intensity of vascularization in the following adjacent pairs of tumors were revealed: TA–TVA, TVA–VA. An increase in the following positions (p < 0.05) in the adjacent pairs is statistically reliable: epithelial cells and fibroblasts (control — TA), epithelial cells, plasma cells and fibrocytes (TA — TVA), epithelial cells, lymphocytes, plasma cells and polymorphonuclear leukocytes (TVA — VA). At the same time in the following sequence “normal mucosa N TA N TVA N VA” there is a gradual increase in the absolute number of all the studied cell populations. In the initial stages of tumor growth (TA), an increase in the number of correlations and activation of cell regulator such as macrophage, which along with fibroblast encloses the number of positive cell relations, is noted. In TVA, as the number of correlations decrease, the macrophage undergoes a peculiar isolation from other cells. In VA, for the first time, at the stages of tumor progression, the number of intercellular correlations reaches to minimum.
Morphologically and Syntactically Annotated Corpora of Many Languages Current State , the Problem and its Significance

Annotated corpora have become a standard resource for research in both linguistics and computational processing of natural languages. Lexicographers judge word usage and distribution by occurrences in corpora; part-of-speech tags may help them narrow their queries. Grammarians may use syntactically annotated corpora (treebanks) for queries such as “show me all examples where a verb governs two objects in the accusative. ” In natural language processing (NLP), syntactic parsing is an important preparatory step for many tasks such as question answering, data mining or machine translation; the state-of-the-art parsers rely on human-annotated treebanks and apply machine learning algorithms to extract linguistic knowledge from the treebanks.
Ambient touch: designing tactile interfaces for handheld devices

This paper investigates the sense of touch as a channel for communicating with miniature handheld devices. We embedded a PDA with a TouchEngineTM --- a thin, miniature lower-power tactile actuator that we have designed specifically to use in mobile interfaces (Figure 1). Unlike previous tactile actuators, the TouchEngine is a universal tactile display that can produce a wide variety of tactile feelings from simple clicks to complex vibrotactile patterns. Using the TouchEngine, we began exploring the design space of interactive tactile feedback for handheld computers. Here, we investigated only a subset of this space: using touch as the ambient, background channel of interaction. We proposed a general approach to design such tactile interfaces and described several implemented prototypes. Finally, our user studies demonstrated 22% faster task completion when we enhanced handheld tilting interfaces with tactile feedback.
Interpersonal differences in social dilemmas: a game theoretical approach

It is easy to observe lack of cooperation in social dilemmas, that is in situations in which persons, by pursuing immediate self-interest, can harm their own group's interest. It is shown first that experimental games (i.e., Prisoner's-, Chicken- and Trust-Dilemma), are capable of capturing the essence of the decisional structure underlying real-world social dilemmas. Next, based upon a review of empirical research, social dilemmas in small groups are contrasted with social dilemmas in large groups. The main purpose of the present study is to examine the effect of factors which are assumed to influence cooperation-rates in social dilemmas involving a large number of persons.

A Case Study of User Vetted Social Networks : DontStayIn

Since their introduction, social network sites (SNSs) have attracted millions of users, many of whom have integrated these sites into their daily practices. As of this writing, there are hundreds of SNSs, with various technological affordances, supporting a wide range of interests and practices. While their key technological features are fairly consistent, the cultures that emerge around SNSs are varied. Most sites support the maintenance of pre-existing social networks, but others help strangers connect based on shared interests, political ones, or activities. Some sites cater to diverse audiences, while others attract people based on common language or shared racial, sexual, religious, or nationality-based identities. Scholars from disparate fields have examined SNSs in order to understand the practices, implications, culture, and meaning of the sites, as well as users' engagement with them. Social network sites might be defined as web-based services that allow individuals to construct a public or semi-public profile within a bounded system, articulate a list of other users with whom they share a connection and traverse their list of connections and those made by others within the system. The nature and nomenclature of these connections may vary from site to site. What makes social network sites unique is not that they allow individuals to meet strangers, but rather that they enable users to articulate and make visible their social networks. This can result in connections between individuals that would not otherwise be made. On many of the large SNSs, participants are not necessarily "networking" or looking to meet new people; instead, they are primarily communicating with people who are already a part of their extended social network. To emphasize this articulated social network as a critical organizing feature of these sites, we label them "social network sites. " DontStayIn DontStayIn, commonly abbreviated to DSI, is a social networking site based around clubbing. Primarily covering the UK it lists nearly 185,000 events and has over 430,000 verified members. The social media on the site is gathered by encouraging members to upload picture galleries to the site for events they've attended, add events and venues and otherwise contribute. One of the most interesting things about dontstayin is the way the site works to build up its user base in a very organic way. If someone were to go clubbing in certain places they might have their picture taken by a spotter from dontstayin who would give them a card saying "you've …
Incorporating network coding to formulate multicast sessions in elastic optical networks

In this paper, we leverage the Set-Cover problem to design the multicast-capable routing, modulation and spectrum assignment (MC-RMSA) algorithms that utilizes network coding (NC) to achieve efficient service provisioning in flexible-grid elastic optical networks (EONs). We use a realistic network model that considers the physical impairments from both transmission and light-splitting, and propose to serve each multicast request with a light-forest that includes one or more light-graphs1 to improve spectrum efficiency. For each multicast request, the proposed algorithms firstly use a Set-Cover approach to select the destination subsets to cover all the destinations. Then, for each subset, we calculate the light-graph to cover all the destination in it. The proposed algorithms are evaluated with extensive simulations for dynamic service provisioning, and the simulation results indicate that they can achieve better performance on blocking probability than existing MC-RMSA algorithms.
High-speed PNP PIN phototransistors in a 0.18 μm CMOS process

In this work we present three speed optimized types of phototransistors built in a standard 180 nm CMOS technology without process modifications. An OPTO ASIC wafer consisting of a p<sup>+</sup> substrate with a low doped p<sup>+</sup> epitaxial layer on top of it is used for the implementation. The phototransistors were produced in 40×40 μm<sup>2</sup> and 100×100 μm<sup>2</sup> sizes. A gain in responsivity of more than 13 and bandwidths up to 50.7 MHz are achieved. As emitter followers, these phototransistors open the opportunity for application where high-speed photosensitive devices with inherent gain are needed. Possible applications are high speed opto-couplers, optical sensors, image sensors, etc.
Rate of Reading Test®: its reliability, and its validity in the assessment of the effects of coloured overlays

A simple reading test that can be undertaken by disabled readers is described. The test is suitable for use in the optometric clinic, taking less than 2 minutes to administer per passage. Test‐retest scores are acceptably reliable. The test reveals increases in the speed of reading when coloured overlays are used both (1) in children who have made long‐term use of coloured overlays for reading, and (2) in children who will subsequently do so.
Optimizing Memory Performance with a JVM : Prefetching in a Mark-and-Sweep Garbage Collector

As processor speeds are increasing faster than memory access times, the distance to memory has become a bottleneck to performance. There are different ways to approach this challenge, in both hardware and software. This thesis project has focused on investigating what software opportunities are available to reduce the memory stall pauses in a Java Virtual Machine (JVM) environment. The JVM in this thesis project, BEA WebLogic JRockit, targets high-performance server applications with demands on high availability and handling critical transaction deadlines. Critical transaction handling puts a high pressure on minimizing pauses in application execution. One software method, data prefetch, was implemented to investigate the effective performance benefits of reducing memory stall. The prefetching was inserted in a parallel mark-and-sweep collector, one of several garbage collectors available with BEA WebLogic JRockit. The tests were carried out on the Intel Itanium Processor Family (IPF) Platform, a 64-bit architecture that has a prefetch instruction available in its instruction set. The experiments showed a significant improvement of the garbage collection pause times with the inserted prefetch optimization. The average pause time was improved by up to 25% for SPECjbb, ultimately enabling a speedup for the application. These results encourage more work to improve performance by targeting optimizations at memory stall times. Optimering av minnesprestanda med en JVM: Prefetching i en mark-and-sweep skräpsamlare
Influential factors of recommendation behaviour in social network sites - an empirical analysis

This paper analyzes influential factors of recommendation behaviour in social network sites (SNSs). Extant research on both SNSs and electronic word of mouth (eWOM) has given insufficient attention to SNSs as a potential eWOM channel. Considering the specificities of SNSs, this paper distinguishes implicit and explicit recommendation behaviour. Drawing upon research on eWOM, SNSs, and knowledge exchange, influential factors of implicit and explicit recommendation behaviour are identified. A theoretical model explaining why SNS users (do not) engage in implicit and explicit recommendation behaviour is developed. Structural equation modeling (SEM) is used for hypothesis testing. Data was collected via an online survey from 832 SNS users. The empirical results show a positive impact of reciprocity on both implicit and explicit recommendation behaviour, a negative impact of fear of producing spam on implicit recommendation behaviour, and a positive impact of both implicit recommendation behaviour and the perceived value of the recommended product on explicit recommendation behaviour
Implementation of a Pragmatic Translation from Haskell into Isabelle / HOL

Among other things the functional programming paradigm – in its pure form – offers the advantage of referential transparency. This facilitates reasoning over programs considerably. Haskell is one of the rare purely functional programming languages that is also of practical relevance. Yet, a comparable success for the verification of Haskell programs has not been achieved, so far. Unfortunately, Haskell lacks a decent theorem prover. On the other hand, the theorem prover Isabelle allows specifying functional programs in its logic HOL. We present an implementation – written in Haskell – which enables to translate Haskell programs into Isabelle/HOL theories. This approach is pragmatic, since its focus is to produce theories that are easily readable and minimise the effort to construct proofs. To this end we had to sacrifice soundness and completeness of the translation. Nevertheless, in practice this kind of translation has proven to be adequate and powerful. We also show some of the techniques that we have used for the implementation including meta programming and generic programming.
Possibility of an electromechanical which-path interferometer

eling through an Aharonov-Bohm ring incorporating a quantum dot in one of the arms are dephased by an interaction with the fundamental flexural mode of a radio-frequency cantilever. The cantilever is positioned so that its tip lies just above the dot and a bias is applied so that an electric field exists between the dot and the tip. This electric field is modified when an additional electron hops onto the dot, coupling the flexural mode of the cantilever and the microscopic electronic degrees of freedom. We analyze the transmission properties of this system and the dependence of interference fringe visibility on the cantilever-dot coupling and on the mechanical properties of the cantilever. The fringes are progressively destroyed as the interaction with the cantilever is turned up, in part due to dephasing arising from the entanglement of the electron and cantilever states and also due to the thermal smearing that results from fluctuations in the state of the cantilever. When the dwell time of the electron on the dot is comparable to or longer than the cantilever period, we find coherent features in the transmission amplitude. These features are washed out when the cantilever is decohered by its coupling to the environment.
Interleukin 2 Signaling Is Required for CD4+ Regulatory T Cell Function

Mice deficient in interleukin (IL)-2 production or the IL-2 receptor α or β chains develop a lethal autoimmune syndrome. CD4+ regulatory T cells have been shown to prevent autoimmune diseases, allograft rejection, and to down-regulate antibody responses against foreign antigens. To assess the role of IL-2 in the generation and function of regulatory T cells, we transferred CD4+ T cells from mice genetically deficient in IL-2 or IL-2Rα (CD25) expression. A small number of splenic or thymic CD4+ T cells from IL-2 knockout mice can protect mice from spontaneous experimental autoimmune encephalomyelitis (EAE). In contrast, splenic or thymic CD4+ T cells from CD25 knockout donor mice conferred little or no protection. We conclude that T cells with regulatory potential can develop, undergo thymic selection, and migrate to the peripheral lymphoid organs in the absence of IL-2, and do not protect from disease by means of IL-2 secretion. However, IL-2 signaling in regulatory T cells is essential for their protective function. Altogether, our results favor a model whereby IL-2 induces regulatory T cell activity.
Processing Load Imposed by Line Breaks in English Temporal Wh-Questions

Prosody plays an important role in online sentence processing both explicitly and implicitly. It has been shown that prosodically packaging together parts of a sentence that are interpreted together facilitates processing of the sentence. This applies not only to explicit prosody but also implicit prosody. The present work hypothesizes that a line break in a written text induces an implicit prosodic break, which, in turn, should result in a processing bias for interpreting English wh-questions. Two experiments—one self-paced reading study and one questionnaire study—are reported. Both supported the “line break” hypothesis mentioned above. The results of the self-paced reading experiment showed that unambiguous wh-questions were read faster when the location of line breaks (or frame breaks) matched the scope of a wh-phrase (main or embedded clause) than when they did not. The questionnaire tested sentences with an ambiguous wh-phrase, one that could attach either to the main or the embedded clause. These sentences were interpreted as attaching to the main clause more often than to the embedded clause when a line break appeared after the main verb, but not when it appeared after the embedded verb.
The Phillips Curve and Long-Term Unemployment

This paper studies the role of long-term unemployment in the determination of prices and wages. Labor market theories such as insider-outsider models predict that this type of unemployed are less relevant in the wage formation process than the newly unemployed. This paper looks for evidence of this behavior in a set of OECD countries. For this purpose, I propose a new specification of the Phillips Curve that contains different unemployment lengths in a time-varying NAIRU setting. This is done by constructing an index of unemployment that assigns different weights to the unemployed based on the length of their spell. The results show that unemployment duration matters in the determination of prices and wages, and that a smaller weight ought to be given to the long-term unemployed. This modified model has important implications for the policy maker: It produces more accurate forecasts of inflation and more precise estimates of the NAIRU. JEL Classification: C22, E31, E50, J64
Query and Update Efficient B + -Tree Based Indexing of Moving Objects

This report presents a way of indexing moving objects with a B + -tree based data structure. This concept was first described 2004 by Jensen, Lin and Ooi in the paper „Query and Update Efficient B + -Tree Based Indexing of Moving Objects“ [1]. Apart from the structure of the index this report also describes how to execute range and kNN queries and how to perform updates on the index.
Antioxidant Activities of Extracts of Trengguli Stem Bark ( Cassia fistula L . )

antioxidant activity on the extract of stem bark C.fistula. The antioxidant activities of C.fistula stem bark extract were evaluated with lipid peroxides test using ferric thiosyanat method (FTC) and 2.6-di-t-butyl-4-metilfenol (BHT) as standard equivalent antioxidant capacity. C.fistula stem bark maceration successively used solvent normal heksane (non polar), ethyl acetate (semi-polar) and methanol (polar). The etyl acetate extract (Ea) shows higher antioxidant activity than the n.hexane extract (Hx) and methanol extract (MeOH). Therefore, the sequence of antioxidant activity is as follows ethyl acetate extract > methanol extract > n.hexane extract, with antioxidant activity consecutively at 5 hours: 65.98%, 58.19% and 32.66%. Those amount are equivalent to the standard synthetic antioxidant BHT (100 ppm), which causes 95.7% antioxidant activity (in 5 hours) inhibition of linoleic acid peroxidation. There is a connection between antioxidant activity of an extract with the content of the total phenol in each extract. From the assay of phenolic extracts with the method of Folin-Ciocalteu reagent (FCR) and also using afzelechin standard as a comparision, we find that the ethyl acetate extract has the highest total phenolic where the entire sequences are as follows: Ea> MeOH> Hx. with total phenol content consecutive 177.55, 123.2167, 7.433333
