SELF OPTIMIZING FINITE STATE MACHINES FOR CONFIDENCE ESTIMATORS

Modern microprocessors are increasingly relying on speculation as a key technique for improving performance and reducing power, temperature and energy. Confidence estimators are necessary to prevent likely misspeculations. These confidence estimators are commonly realized using a Finite State Machine (FSM) called a saturating counter. This paper presents a hardware method that allows FSMs to dynamically optimize their state transitions and confidence thresholds to improve CPU performance by automatically adapting to the current workload. The technique further allows the FSMs to continuously adjust to changing program conditions. These adaptable, self-optimizing confidence estimators are evaluated as a component in a value predictor on the C programs from the SPECcpu2000 benchmark suite. On average, the self-optimizing method achieves a miss rate reduction of 11% with a maximum of 47%. The selfoptimizing confidence estimator can provide a speedup of 4%.
Beyond anarchy: Self-organized topology for peer-to-peer networks

In this article, we discuss the new constraints that will apply to future, highly dynamic networks and investigate one of the major problems that is likely to affect their deployment: traffic/workload distribution. Starting with a very simple model, we demonstrate that a structure made of undifferentiated subunits will almost inevitably hit a scalability barrier, unless new design rules are applied. We then give quantitative evidence that a hybrid network topology termed the "hypergrid" could have the potential of solving some of the most critical problems (relay overload and network vulnerability), yet could still be produced by applying local rules only.

Performance Bound Analysis of Variable Gain Relaying over Non-identical Nakagami-m Fading Channel

This paper derives the tight performance bound for average bit error probability (ABEP) of binary phase shift keying (BPSK) modulation and multiple amplitude modulation (M-AM), using variable gain relaying, over non-identical Nakagami-m fading channel. Additionally, we present other performance measures including approximate moments and amounts of fading (AoF). Numerical and simulation results show that the deduced performance bound is a tight lower bound especially at medium and high signal-to-noise ratio (SNR).
A novel approach to model design and tuning through automatic parameter screening and optimization theory and application to a helicopter flight simulator case-study

The aim of this paper is to describe a novel methodology for model-design and tuning in computer simulations, based on automatic parameter screening and optimization. Simulation requires three steps: mathematical modelling, numerical solution, and tuning of the model's parameters. We address Tuning because, at the state-of-the-art, the development of life-critical simulations requires months to appropriately tune the model. Our methodology can be split in Screening (identification of the relevant parameters to simulate a system) and Optimization (search of optimal values for those parameters). All techniques are fully general, because they leverage ideas from Machine-Learning and Optimization Theory to achieve their goals without directly analysing the simulator's mathematical model. Concerning screening, we show how Machine-Learning algorithms, based on Neural Networks and Logistic Regression, can be used for ranking the parameters according to their relevance. Concerning optimization, we describe two algorithms: an adaptive hill-climbing procedure and a novel strategy, specific for model tuning, called sequential masking. Eventually, we show the performances achieved and the impact on the time and effort required for tuning a helicopter flight-simulator, proving that the proposed techniques can significantly speed-up the process.

A Scenario-Driven Approach to Trace Dependency Analysis

Software development artifacts-such as model descriptions, diagrammatic languages, abstract (formal) specifications, and source code-are highly interrelated where changes in some of them affect others. Trace dependencies characterize such relationships abstractly. This paper presents an automated approach to generating and validating trace dependencies. It addresses the severe problem that the absence of trace information or the uncertainty of its correctness limits the usefulness of software models during software development. It also automates what is normally a time consuming and costly activity due to the quadratic explosion of potential trace dependencies between development artifacts.
Neural changes accompanying tinnitus following unilateral acoustic trauma in the guinea pig

Animal models of tinnitus allow us to study the relationship between changes in neural activity and the tinnitus percept. Here, guinea pigs were subjected to unilateral noise trauma and tested behaviourally for tinnitus 8 weeks later. By comparing animals with tinnitus with those without, all of which were noise‐exposed, we were able to identify changes unique to the tinnitus group. Three physiological markers known to change following noise exposure were examined: spontaneous firing rates (SFRs) and burst firing in the inferior colliculus (IC), evoked auditory brainstem responses (ABRs), and the number of neurons in the cochlear nucleus containing nitric oxide synthase (NOS). We obtained behavioural evidence of tinnitus in 12 of 16 (75%) animals. Both SFRs and incidences of burst firing were elevated in the IC of all noise‐exposed animals, but there were no differences between tinnitus and no‐tinnitus animals. There were significant decreases in ipsilateral ABR latencies in tinnitus animals, contrary to what might be expected with a small hearing loss. Furthermore, there was an ipsilateral–contralateral asymmetry in NOS staining in the ventral cochlear nucleus (VCN) that was only apparent in tinnitus animals. Tinnitus animals had a significantly greater number of NOS‐containing neurons on the noise‐exposed side, whereas no‐tinnitus animals did not. These data suggest that measuring NOS in the VCN and recording ABRs supplement behavioural methods for confirming tinnitus in animals, and that nitric oxide is involved in plastic neural changes associated with tinnitus.
Waiting for the Top Quark Mass , K + → π + νν̄ , B 0 s-B̄ 0 s Mixing and CP Asymmetries in B-Decays ∗

Anticipating improved determinations of mt, | Vub/Vcb |, BK and FB √ BB in the next five years we make an excursion in the future in order to find a possible picture of the unitarity triangle, of quark mixing and of CP-violation around the year 2000. We then analyse what impact on this picture will have the measurements of four possibly cleanest quantities: BR(K+ → π+νν̄), xd/xs, sin(2α) and sin(2β). Our analysis shows very clearly that there is an exciting time ahead of us. In the course of our investigations we extend the analysis of the unitarity triangle beyond the leading order in λ and we derive several useful analytic formulae for quantities of interest.

Design of Components for a Compact Ultra Wideband Microwave Imaging System

The paper describes the design of hybrid circuits and antennas for a compact ultra wideband (UWB) microwave imaging system aimed at operation from 3.1 to 10.6GHz. The design of these components is accomplished with the use of full-wave electromagnetic field analysis and design software. The components are developed and experimentally tested. They show good electrical performances over the specified band and thus they are ready to be incorporated in the proposed configurations of an UWB microwave imaging system.
Contextual Bookmarks

The role of digital information in everyday life divides out activities in interacting with the physical and the digital world. There is no connection between these worlds that is easily accessible, even though physical objects, persons, and real world events often have digital counterparts. The physical reality is actually overlaid by an additional virtual or digital layer. As we are acting in the physical and the digital world it is desirable that we can use links that bridge the gap between both worlds. In this paper we describe our approach to narrow this gap. Starting from a scenario that shows the demand for such connections, we present an architecture that allows users to bookmark specific situations. Based on these contextual bookmarks the user can request additional digital information. Our first prototype enables the user to bookmark content shown on public displays by taking photos of the display using a mobile phone. Our system combines content analysis of the photo with context information such as position, creation time, etc. in order to form the basis to establish a link to the digital world. The presented architecture will serve as a flexible solution to find and integrate further connections between the physical and the digital world.
Yeast Eps15-like endocytic protein Pan1p regulates the interaction between endocytic vesicles, endosomes and the actin cytoskeleton

The actin cytoskeleton plays important roles in the formation and internalization of endocytic vesicles. In yeast, endocytic vesicles move towards early endosomes along actin cables, however, the molecular machinery regulating interaction between endocytic vesicles and actin cables is poorly understood. The Eps15-like protein Pan1p plays a key role in actin-mediated endocytosis and is negatively regulated by Ark1 and Prk1 kinases. Here we show that pan1 mutated to prevent phosphorylation at all 18 threonines, pan1-18TA, displayed almost the same endocytic defect as ark1Δ prk1Δ cells, and contained abnormal actin concentrations including several endocytic compartments. Early endosomes were highly localized in the actin concentrations and displayed movement along actin cables. The dephosphorylated form of Pan1p also caused stable associations between endocytic vesicles and actin cables, and between endocytic vesicles and endosomes. Thus Pan1 phosphorylation is part of a novel mechanism that regulates endocytic compartment interactions with each other and with actin cables. DOI: http://dx.doi. org/10.7554/eLife.10276. 001
Alterations in the expression of GABAA receptor subunits in cerebellar granule cells after the disruption of the α6 subunit gene

Any given subunit of the heteromultimeric type‐A γ‐aminobutyric acid (GABA) GABAA receptor may be present in several receptor subtypes expressed by individual neurons. Changes in the expression of a subunit may result in differential changes in the expression of other subunits depending on the subunit composition of the receptor subtype, leading to alterations in neuronal responsiveness to GABA. We used the targeted disruption of the α6 subunit gene to test for changes in the expression of other GABAA receptor subunits. Immunoprecipitation and ligand binding experiments indicated that GABAA receptors were reduced by ≈ 50% in the cerebellum of α6 –/– mice. Western blot experiments indicated that the α6 subunit protein completely disappeared from the cerebellum of α6 –/– mice, which resulted in the disappearance of the δ subunit from the plasma membrane of granule cells. The amount of β2, β3 and γ2 subunits was reduced by ≈ 50%, 20% and 40%, respectively, in the cerebella of α6 –/– mice. A comparison of the reduction in the level of α1, β2, β3, γ2, or δ‐subunit‐containing receptors in α6 –/– cerebellum with those observed after removal of α6‐subunit‐containing receptors from the cerebella of α6 +/+ mice by immuno‐affinity chromatography demonstrated the presence of a significantly higher than expected proportion of receptors containing β3 subunits in α6 –/– mice. The receptors containing α1, β2, β3 and γ2 subunits were present in the plasma membrane of granule cells of α6 –/– mice at both synaptic and extrasynaptic sites, as shown by electron microscopic immunocytochemistry. Despite the changes, the α1 subunit content of Golgi‐cell‐to‐granule‐cell synapses in α6 –/– animals remained unaltered, as did the frequency of α1 immunopositive synapses in the glomeruli. Furthermore, no change was apparent in the expression of the α1, β2 and γ2 subunits in Purkinje cells and interneurons of the molecular layer.
New Century, Old Disparities: Gender and Ethnic Wage Gaps in Latin America

This paper surveys gender and ethnic wage gaps in 18 Latin American countries, decomposing differences using matching comparisons as a non-parametric alternative to the Blinder-Oaxaca (BO) decomposition. It is found that men earn 9-27 percent more than women, with high cross-country heterogeneity. The unexplained pay gap is higher among older, informal and self-employed workers and those in small firms. Ethnic wage differences are greater than gender differences, and educational attainment differentials play an important role in explaining the gap. Higher ethnic wage gaps are found among males, singleincome generators of households and full-time workers, and in rural areas. An important share of the ethnic wage gap is due to the scarcity of minorities in highpaid positions.
Web Catchphrase Improve System Employing Onomatopoeia and Large-Scale N-gram Corpus

In this paper, we propose a system which improves text catchphrases on the web using onomatopoeia and the Japanese Google N-grams. Onomatopoeia is regarded as a fundamental tool in daily communication for people. The proposed system inserts an onomatopoetic word into plain text catchphrases. Being based on a large catchphrase encyclopedia, the proposed system evaluates each catchphrase’s candidates considering the words, structure and usage of onomatopoeia. That is, candidates are selected whether they contain onomatopoeia and they use specific catchphrase grammatical structures. Subjective experiments show that inserted onomatopoeia is effective for making attractive catchphrases.
Finding Influential Institutions in Bibliographic Information Networks

Ranking in bibliographic information networks is a widely studied problem due to its many applications such as advertisement industry, funding, search engines, etc. Most of the existing works on ranking in bibliographic information network are based on ranking of research papers and their authors. But the bibliographic information network can be used for solving other important problems as well. The KDD Cup $2016$ competition considers one such problem, which is to measure the impact of research institutions, i.e. to perform ranking of research institutions. The competition took place in three phases. In this paper, we discuss our solutions for ranking institutions in each phase. We participated under team name "anu@TASL" and our solutions achieved the average NDCG@$20$ score of $0.7483$, ranking in eleventh place in the contest.
Creating user interfaces for econometric routines with JStatCom: An example for Ox

JStatCom is a new software framework that simplies the creation of graphical user interface components for mathematical procedures. 1 It is written in Java and oers a coherent approach to creating applications for data based analysis. Programming with JStatCom is ecien t, because existing algorithms written in various popular matrix languages can be reused with little or no changes required. The paper shows how this system can be applied to provide an existing Ox program with a feature-rich graphical user interface with relatively little eort. One of the advantages of the presented approach is the strict separation of user interface and algorithm code. Although the framework provides standard solutions for common tasks, it can be extended and customized in various directions.
Cytoskeletal Actin Gates a Cl− Channel in Neocortical Astrocytes

Increases in astroglial Cl− conductance accompany changes in cell morphology and disassembly of cytoskeletal actin, but Cl− channels underlying these conductance increases have not been described. We characterize an outwardly rectifying Cl− channel in rodent neocortical cultured astrocytes and describe how cell shape and cytoskeletal actin modulate channel gating. In inside-out patch-clamp recordings from cultured astrocytes, outwardly rectifying Cl− channels either were spontaneously active or inducible in quiescent patches by depolarizing voltage steps. Average single-channel conductance was 36 pS between −60 and −80 mV and was 75 pS between 60 and 80 mV in symmetrical (150 mm NaCl) solutions. The permeability ratio (PNa/PCl) was 0.14 at lower ionic strength but increased at higher salt concentrations. Both ATP and 4,4-diisothiocyanostilbene-2,2′-disulfonic acid produced a flicker block, whereas Zn2+ produced complete inhibition of channel activity. The frequency of observing both spontaneous and inducible Cl− channel activity was markedly higher in stellate than in flat, polygonally shaped astrocytes. In addition, cytoskeletal actin modulated channel open-state probability (PO) and conductance at negative membrane potentials, controlling the degree of outward rectification. Direct application of phalloidin, which stabilizes actin, preserved lowPO and promoted lower conductance levels at negative potentials. Lower PO also was induced by direct application of polymerized actin. The actions of phalloidin and actin were reversed by coapplication of gelsolin and cytochalasin D, respectively. These results provide the first report of an outwardly rectifying Cl− channel in neocortical astrocytes and demonstrate how changes in cell shape and cytoskeletal actin may control Cl− conductance in these cells.
A Novel Interface for Eddy Current Displacement Sensors

In this paper, we propose a novel interface concept for eddy current displacement sensors. A measurement method and a new front-end circuit are also proposed. The front-end circuit demonstrates excellent thermal stability, high resolution, and low-power consumption. The proposed idea is analytically investigated. The demodulation principle, as well as the interface implementation, is also addressed. This interface is being introduced for measuring submicrometer displacements in medium- to high-resolution applications. The interface system consumes less than 12 mW and has an extremely low thermal drift. The interface circuit will be implemented as a system-in-a-package (SIP). The full-scale range of displacement is 1 mm with 50-kHz signal bandwidth and 11-bit resolution (less than 500 nm). The signal conditioning circuit utilizes a standard 0.35- mum complementary metal-oxide semiconductor (CMOS) technology. Simulation results, which were achieved on the basis of experimental results of testing a prototype coil, also confirm the high performance of the interface system, as expected from analytical results. Compared with previous reports, this low-power interface system demonstrates a much lower temperature drift.
Americas Conference on Information Systems ( AMCIS ) 1231-2006 Consumer Motivations to Search E-Health Information

E-health information has become an important resource for people seeking health information. Even though many studies have been conducted to examine the quality of e-health information, only a few studies have explored the effects of e-health information seekers’ motivations on perceived quality of e-health information. There is even less information about repeated search for e-health information after users’ initial ‘experience’ of e-health information use. Using an online survey of information seekers, 252 e-health information users’ responses were collected. The research examines the relationship between motivation, perceived quality, satisfaction and intention to repeat-search e-health information. The results identify motivations to search e-health information, and confirm the relationship between motivation, perceived quality dimensions, satisfaction and intention to repeat-search for e-health information.
