2 Creating a Domain-Specific Sentiment Lexicon

The explosion of user-generated content, especially tweets, customer reviews, makes it possible to build sentiment lexicons automatically by harnessing the consistency between the content and its accompanying emotional signal, either explicitly or implicitly. In this work we describe novel techniques for automatically producing domain specific sentiment lexicons that are optimised for the language patterns and idioms of a given domain. We describe how we use review ratings as sentiment signals. We also describe an approach to recognising contextual variations in sentiment and show how these variations can be exploited in practice. We evaluate these ideas in a number of different product domains.
Packaged high power MUTC photodetectors for high SFDR applications

High-power high linearity photodetectors are desirable for applications that require high spurious free dynamic range (SFDR), such as a receive mode antenna employing a photonic link. Both the output third order (OIP3) and output second order intercept point (OIP2) of the photodetector can cause a reduction in SFDR, where OIP3 is of concern for distortion close to the fundamentals [1] and OIP2 for wideband applications [2]. Recently a packaged modified uni-traveling carrier (MUTC) photodetector was demonstrated [3]. Here we analyze those devices from both the RF power performance as well as SFDR performance for narrow and wideband link applications.
An efficient conflict-free memory-addressing unit for SIMD VLIW DSP

With the rapid expansion in multi-media and signal processing applications, DSP processors with high-performance execution and low-power consumption evoke to be the trend. As these applications are often characterised by a huge number of data accesses, the computation efficiency often be heavily decreased by bank conflicts on account of non-aligned and irregular data accesses. This paper presents an efficient memory accessing unit called Mod-N Address for the DSP processor. The unit is designed for solving bank conflicts when data accessing is irregular or not aligned. The proposed architecture implements the conflict-free access by generating addresses through modulus operation and accessing along the diagonal. The structure adjusts the sequence of data when accessing and requires quite little changes to the instruction set. The unit had been implemented on our platform BWDSP104x, and the experimental results had shown that proposed unit achieves an 45% accelerate rate for FFT algorithm compared with the previous scheme. According to the comparison with the conventional methods, experimental evaluations also show that mod-N address can outperform by an average of 7.9% to 60% in performance.
The Managerial Grid

Impoverished management Minimum effort to get the work done. A basically lazy approach that avoids as much work as possible. Authority-compliance Strong focus on task, but with little concern for people. Focus on efficiency, including the elimination of people wherever possible. Country Club management Care and concern for the people, with a comfortable and friendly environment and collegial style. But a low focus on task may give questionable results. Middle of the road management A weak balance of focus on both people and the work. Doing enough to get things done, but not pushing the boundaries of what may be possible. Team management Firing on all cylinders: people are committed to task and leader is committed to people (as well as task).

An ecological economic assessment of risk reducing effects of species diversity in grassland production

We investigate the relationship between yield stability and species diversity in managed grasslands. To this end, ecological economic and econometric frameworks are developed and applied to evaluate potential risk-reducing effects of species diversity from a farmer’s perspective. Our empirical analysis is based on a rich panel data set obtained from a diversity experiment covering in total 60 species and a period of 6 years. We find empirical evidence for the risk-reducing effect of species diversity and the economic assessment reveals significant insurance values associated with diversity for a risk averse decision maker. Thus, the economic value of diversity would be underestimated if not accounting for this property and species diversity serves as valuable ex-ante risk management strategy.
The JAK2 V617F mutation frequently occurs in patients with portal and mesenteric venous thrombosis

Summary. Background: Myeloproliferative disorders (MPDs) represent a risk factor for thrombosis in the portal, mesenteric, and hepatic districts. Objective: We aimed to assess whether the Janus kinase 2 (JAK2) V617F mutation, an acquired mutation that occurs in MPD patients, is a risk factor for portal and mesenteric venous thrombosis (PMVT) independently of the presence of overt MPDs. Patients and methods: The medical histories of 99 patients presenting with PMVT were obtained. The presence of the JAK2 V617F and VHL 598C > T mutations was determined by polymerase chain reaction followed by restriction enzyme analysis and direct cycle sequence analysis. Results: Over a 10‐year period of observation, of the 99 patients presenting with PMVT, the JAK2 V617F mutation was detected in heterozygous state in 17 individuals [17.2%; 95% confidence interval (95% CI) 10.9–25.9]. None of the patients presenting with the JAK2 V617F mutation carried an inherited thrombophilic risk factor. Seven patients with (43.8%; 95% CI 19.8–70.1) and two without (2.4%; 95% CI 0.3–8.4) the JAK2 V617F mutation had a diagnosis of MPD at the occurrence of the venous thrombotic event. After a median follow‐up of 41 months (range 3–114 months), three out of the 10 patients carrying the JAK2 V617F mutation were then diagnosed as having idiopathic myelofibrosis (n = 2) or polycythemia vera (n = 1), whereas in seven patients a MPD was not detected. Two of the 83 patients without the JAK2 V617F mutation went on to develop MPDs. Conclusions: Determination of the JAK2 V617F mutation may contribute to the search for genetic determinants of PMVT and may be useful to recognize patients who should be carefully observed for the subsequent development of overt MPDs.
Prédiction du montant levé lors d'une campagne de financement participatif par la méthode des plus proches voisins

Résumé. Le financement participatif est un mode de financement d’un projet faisant appel à un grand nombre de personnes, contrairement aux modes de financement traditionnels. Il a connu une forte croissance avec l’émergence d’Internet et des réseaux sociaux. Cependant plus de 60 % des projets ne sont pas financés, il est donc important de bien préparer sa campagne de financement. De plus, en cours de campagne, il est crucial d’avoir une estimation rapide de son succès afin de pouvoir réagir rapidement (restructuration, communication) : des outils de prédiction sont alors indispensables. Nous proposons dans cet article une méthode de prédiction du montant final levé lors d’une campagne de financement participatif utilisant l’algorithme k-NN : en utilisant l’historique de campagnes passées, nous déterminons celles qui sont les plus similaires à une campagne en cours. Nous utilisons alors les montants finaux pour faire une estimation. Nous comparons plusieurs mesures de distance pour déterminer les plus proches voisins. Nos résultats indiquent que le dernier état d’une campagne seul est suffisant pour obtenir une bonne prédiction.
Changing of SYNTAX score performing fractional flow reserve in multivessel coronary artery disease

Objectives To investigate the relationship between classic SYNTAX and functional SYNTAX score guided by fractional flow reserve (FFR). Background SYNTAX score predicts clinical outcome after percutaneous coronary intervention in patients with multivessel coronary artery disease (CAD), based on data from angiography alone. However, in the clinical setting, decision-making on myocardial revascularization should be guided by reliable demonstration of inducible ischemia, as detected by FFR. Methods FFR was collected in all 50–90% angiographic stenoses of 39 consecutive patients with stable multivessel CAD. SYNTAX score was calculated as usually described in SYNTAX group's reports. A functional SYNTAX (F-SYNTAX) score was determined by only considering ischemia-producing lesions (FFR ⩽ 0.80). The two scores were compared with correlation, Bland–Altman and agreement tests. Results FFR was measured in 97 lesions, with a median value of 0.82 ± 0.10. In the 50–70% and 70–90% category stenoses, FFR was greater than 0.80 in 68 and 16% of cases, respectively. F-SYNTAX was systematically inferior to SYNTAX score, with a median difference of 8.4 ± 7.4 (P < 0.05). The correlation between the two methods was globally weak (r = 0.621, rho = 0.563; P < 0.001). After determining F-SYNTAX score, more than 30% of the patients moved to a lower-risk tertile group (P = 0.003). No clinical and angiographic differences were found between patients whether or not reclassified in lower-risk tertiles with F-SYNTAX score. Conclusions In patients with multivessel CAD, implementation of SYNTAX score with FFR seems to be a more rational approach for revascularization. F-SYNTAX score reclassifies a significant proportion of patients to a lower-risk profile, thus leading to a possible change of therapeutic strategy.
One Thing You Did Not Know About Variance Swaps

In this paper we elaborate on what is commonly referred to as the Skew Delta of a Variance Swap, i.e. the sensitivity of the fair strike of a variance swap relative to moves in the underlying's spot price. In particular we examine whether or not a pure variance product such as a variance swap should be hedged with an offsetting delta on the spot.
Visual Analysis of Trajectories in Multi‐Dimensional State Spaces

Multi‐dimensional data originate from many different sources and are relevant for many applications. One specific sub‐type of such data is continuous trajectory data in multi‐dimensional state spaces of complex systems. We adapt the concept of spatially continuous scatterplots and spatially continuous parallel coordinate plots to such trajectory data, leading to continuous‐time scatterplots and continuous‐time parallel coordinates. Together with a temporal heat map representation, we design coordinated views for visual analysis and interactive exploration. We demonstrate the usefulness of our visualization approach for three case studies that cover examples of complex dynamic systems: cyber‐physical systems consisting of heterogeneous sensors and actuators networks (the collection of time‐dependent sensor network data of an exemplary smart home environment), the dynamics of robot arm movement and motion characteristics of humanoids.
Cross Cultural Interactions: Methods and Motivations for Study

Human factors practitioners have become increasingly aware of the need for attending to team interaction dynamics. This has produced substantial research, methodological advances and, ultimately, recommendations for team design, training, interaction support and assessment. Concurrently, awareness has grown that cross cultural differences influence the usability and safety of technologies. To date, however, human factors practitioners have rarely considered the intersection of these two topics: cross cultural interactions in team performance settings and/or the design and assessment of multi-cultural teams (and of technologies to support them). This panel will review the motivation for such research and a variety of approaches to conducting it. Central themes will be (a) definitions and dimensions of cultural differences, (b) team performance assessment methodologies appropriate and useful in cross-cultural team research, and (c) cross-cultural team design, training and aiding methodologies that are the targets of such research.
Visual function and compensatory mechanisms for hemianopia after hemispherectomy in children

Little is known about the functional visual outcome of children after hemispherectomy. Several case reports have described an anomalous head posture (AHP) and exotropia (XT) contralateral to the side of early brain damage, as possible compensatory mechanisms (CMs) for homonymous hemianopia (HH). The aim of this study was to determine visual outcome and the prevalence of such CMs in hemispherectomized children.
Study the Changes in (pH, Turbidity, Hardness, and Total Organic Carbon) Levels of Water using Plant Membrane (Palm Leaves Powder) and Aquatic Plant System (Vine Stems)

Due to the increasing industrialization and urbanization, the requirement of clean water has been growing quite fast and it has the potential to keep increasing. There are many regions facing water crisis even some countries with a rich water source. In this study, three types of water (tap, ground, and light sewage) have been collected from different places in Ibrahim Ahmad site in Sulaymaniyah city/Kurdistan region – Iraq. The research studies the effects of plant membrane method, and aquatic plant system on the improvement of pH, turbidity, hardness, and total organic carbon (TOC) of water samples. In the plant membrane, palm leaves were crushed and used as a powder in filter bags; whereas in the aquatic plant system, vine stems were used by growing up the vines. The experimental results showed that the pH, hardness, turbidity, and TOC of water samples after using palm leaves powder and vine stems have been changed significantly with slight variation in some test results. The results of turbidity showed that using palm leaves powder as plant membrane was more effective than the vine stems in an aquatic plant system. On the other hand, the results of hardness and TOC tests of all water samples after using both methods proved that the vine stems method was more reliable than the palm leaves method. Finally, the pH results of all water samples after using both methods have been decreased to the normal range with a slight variation between the vine stems and palm leaves methods.
Role of Hepatitis C Virus Genotype in the Development of Severe Transaminase Elevation After the Introduction of Antiretroviral Therapy

Objective: To assess the role of different hepatitis C virus (HCV) genotypes in the development of transaminase elevation after treatment with highly active antiretroviral therapy (HAART). Design: Retrospective cohort study at one referral HIV outpatient clinic. Methods: HCV genotype was determined in plasma samples from all consecutive HCV‐HIV coinfected patients initiating HAART between March 1998 and January 2000. Clinical and laboratory data were recorded during the following 9 months. Severe transaminase elevation was defined as ≥ fivefold increase over upper normal limits (AIDS Clinical Trials Group grades 3 or 4) when baseline alanine transaminase (ALT) and aspartate transaminase (AST) values were normal, and as ≥ 3.5‐fold increase above baseline ALT and AST values if they were abnormal. Results: Twelve of 70 subjects (17%) developed severe transaminase elevation. Their HCV genotypes were distributed as follows: type 1, 5/39 (13%); type 2, 0/3 (0%); type 3, 7/21 (33%); and type 4, 0/7 (0%). The incidence of severe transaminase elevation was significantly higher among subjects with HCV genotype 3 (HCV‐3) compared with those with non‐type 3 (OR, 4.4 [95%CI, 1.2‐16.1]; P = .02). In the multivariate analysis, HCV‐3 remained associated with severe transaminase elevation when adjusted for baseline HCV viral load and degree of immune recovery seen during follow‐up evaluation. Conclusions: HCV‐3 is an independent risk factor for developing severe transaminase elevation after HAART. HCV genotyping before initiating antiretroviral therapy may be useful for assessing the risk of hepatotoxicity and for choosing the most appropriate drugs to prescribe for HIV‐HCV coinfected patients. Given that the best response to interferon plus ribavirin occurs in patients with HCV‐3, treatment should be specially encouraged in coinfected persons carrying HCV‐3.
Analysis of Secret Key Robustness in Indoor Radio Channel Measurements

In the recent years, a set of works have addressed inherent characteristics of the fading propagation channel in an information-theoretic framework oriented towards security. In particular, for cryptographic purposes, secure key bits can be extracted from reciprocal radio channels, seen as a shared source of randomness between any two entities. In this paper we intend to assess the impact of true radio channel features on the security performance, by quantizing the complex channel coefficients into discrete key bits. To this end, indoor channel measurements were performed and investigated in different scenarios, e.g. LOS/NLOS condition, narrowband (NB) as well as wide band (WB) targeting OFDM systems. Secret key robustness is firstly studied for the legitimate terminals in terms of key bit disagreement ratio and key randomness, and secondly by considering an eavesdropper in a wide set of positions around these terminals and by evaluating the difference between the generated keys. A simplified channel model is also analyzed in comparison with the measured channels, as regards the characteristics of generated key bits.
A biochemical mechanism for the oncogenic potential of the p110β catalytic subunit of phosphoinositide 3-kinase

Class I PI3-kinases signal downstream of receptor tyrosine kinases and G protein-coupled receptors and have been implicated in tumorigenesis. Although the oncogenic potential of the PI3-kinase subunit p110α requires its mutational activation, other p110 isoforms can induce transformation when overexpressed in the wild-type state. In wild-type p110α, N345 in the C2 domain forms hydrogen bonds with D560 and N564 in the inter-SH2 (iSH2) domain of p85, and mutations of p110α or p85 that disrupt this interface lead to increased basal activity and transformation. Sequence analysis reveals that N345 in p110α aligns with K342 in p110β. This difference makes wild-type p110β analogous to a previously described oncogenic mutant, p110α-N345K. We now show that p110β is inhibited by p85 to a lesser extent than p110α and is not differentially inhibited by wild-type p85 versus p85 mutants that disrupt the C2–iSH2 domain interface. Similar results were seen in soft agar and focus-formation assays, where p110β was similar to p110α-N345K in transforming potential. Inhibition of p110β by p85 was enhanced by a K342N mutation in p110β, which led to decreased activity in vitro, decreased basal Akt and ribosomal protein S6 kinase (S6K1) activation, and decreased transformation in NIH 3T3 cells. Moreover, unlike wild-type p110β, p110β-K342N was differentially regulated by wild-type and mutant p85, suggesting that the inhibitory C2–iSH2 interface is functional in this mutant. This study shows that the enhanced transforming potential of p110β is the result of its decreased inhibition by p85, due to the disruption of an inhibitory C2–iSH2 domain interface.
How to optimise drug study design: pharmacokinetics and pharmacodynamics studies introduced to paediatricians

In children, there is often lack of sufficient information concerning the pharmacokinetics (PK) and pharmacodynamics (PD) of a study drug to support dose selection and effective evaluation of efficacy in a randomised clinical trial (RCT). Therefore, one should consider the relevance of relatively small PKPD studies, which can provide the appropriate data to optimise the design of an RCT.
Mechanical and muscular coordination patterns during a high-level fencing assault.

PURPOSE This study aimed to investigate the coordination of lower limb muscles during a specific fencing gesture in relation to its mechanical effectiveness. METHODS Maximal isokinetic concentric and isometric plantarflexor, dorsiflexor, knee and hip extensor and flexor torques of 10 female elite saber fencers were assessed and compared between both legs. Sabers completed three trials of a specific fencing gesture (i.e., marché-fente) on a 6.60-m-long force platform system. Surface EMG activities of 15 lower limb muscles were recorded in time with ground reaction forces and separated into four distinct assault phases. EMG signals were normalized to the muscle activity assessed during maximal isometric contraction. Mechanical and EMG data were compared between both legs over the entire assault and in each phase (ANOVA). Potential correlations between muscle strength and average EMG activities were tested (Bravais-Pearson coefficient). RESULTS EMG activity patterns showed that rear hip and knee extensor and plantarflexor muscles were mainly activated during propulsive (concentric) phases, while front hip and knee extensor muscles were strongly solicited during the final braking (eccentric) phase to decelerate the body mass. Although fencers presented greater maximal hip (+10%) and knee (+26%) extensor strength in the front than in the rear leg (P < 0.05), rear hip and knee extensor strength was significantly correlated to the maximal anteroposterior velocity (r = 0.60-0.81). Moreover, muscle activity of the rear extensors was related to average velocity during the second propulsive phase (phase 3). CONCLUSIONS This study gathers the first evidence of a crucial role of the rear extensor muscles in fencing speed performance. Such findings suggest interesting perspectives in the definition of specific training or rehabilitation programs for elite fencers.
Routing via Functions in Virtual Networks: The Curse of Choices

An important evolution of the users’ needs is represented by the on-demand access to the network, storage, and compute resources in order to dynamically match the level of resource consumption with their service requirements. The response of the network providers is to transition to an architecture based on softwarization and cloudification of the network functions. This is the rationale for the deployment of network functions virtualization (NFV) where virtual network functions (VNFs) may be chained together to create network services. Efficient online routing of demand across nodes handling the functions involved in a given service chain is the novel problem that we address in this paper. We provide an original formulation of this problem that includes link and CPU capacity constraints and is based on the construction of an expanded network. We derive the exact mathematical formulation and propose several heuristic algorithms taking into account the main system’s parameters. We conclude by deriving some interesting insights both about the algorithms and the network performance by comparing the heuristics with the exact solutions.
A Sample of One: First-Person Research Methods in HCI

First-person research (i.e., research that involves data collection and experiences from the researcher themselves) continues to become a viable addition and, possibly even, alternative to more traditional HCI methods. While we have seen the benefits of using methods such as autoethnography, autobiographical design, and autoethnographical research through design, we also see the need to further explore, define, and investigate the practices, techniques, tactics, and implications of first-person research in HCI. To address this, this one-day workshop aims to bring together a community of researchers, designers, and practitioners who are interested in exploring and reimagining research in HCI and interaction design, with an emphasis on first-person methods.
