Fixed-StructureLPV-IOControllers : An Implicit RepresentationBasedApproach ⋆

In this note, novel linear matrix inequality (LMI) analysis conditions for the stability of linear parameter-varying (LPV) systems in input-output (IO) representation form are proposed together with bilinear matrix inequality (BMI) conditions for fixedstructure LPV-IO controller synthesis. Both the LPV-IO plant model and the controller are assumed to depend affinely and statically on the scheduling variables. By using an implicit representation of the plant and the controller interaction, an exact representation of the closed-loop behavior with affine dependence on the scheduling variables is achieved. This representation allows to apply Finsler’s Lemma for deriving exact stability as well as exact quadratic performance conditions. A DK-iteration based solution is carried out to synthesize the controller. The main results are illustrated by a numerical example.
Clinical efficacy of intravenous thrombolysis with alteplase in treatment of elderly patients with minor stroke and its effect on prognosis

Objective: This study aims to explore the clinical efficacy of intravenous thrombolysis with alteplase in the treatment of elderly patients with minor acute ischemic stroke (AIS) and its effect on prognosis. Methods: One hundred and twenty elderly patients with AIS, older than 75 years old, were retrospectively analyzed, who were divided into an observation group and a control group (both n=60). Patients in the control group were conventionally treated, and patients in the observation group were treated with intravenous thrombolysis with alteplase for injection (0.6 mg/kg) on the basis of conventional treatment. Patients in the two groups were treated for 3 consecutive months. The National Institutes of Health Stroke Scale (NIHSS) score 24 hours after admission and 90 days after treatment was used to evaluate the neurological impairment, and the modified Rankin Scale (mRS) score 90 days after treatment was used to evaluate the prognosis. Factors affecting the prognosis of thrombolytic therapy were analyzed, and changes of N-terminal-pro-brain natriuretic peptide (NT-pro-BNP) expression were observed 24 hours after admission and 14 days after treatment. The clinical efficacy, NIHSS and mRS scores before and after treatment, and thrombolytic therapy-related complications were compared between the two groups. The receiver operating characteristic (ROC) curve was plotted according to the multivariate analysis of significant indicators, to analyze the impact of the indicators on the efficacy. Results: In the observation and control groups, the NIHSS score and NT-pro-BNP expression after treatment were significantly lower than those before treatment (P<0.001). The two indicators in the observation group were significantly lower than those in the control group (P<0.001), and for the both indicators, the difference during treatment was significantly greater in the observation group than that in the control group (P<0.001). There was no statistically significant difference in adverse reactions between the two groups (P>0.05). Compared with the control group, patients in the observation group had significantly better clinical efficacy (P<0.05), and prognosis (P<0.05). According to multivariate logistic regression analysis, the NIHSS score 24 hours after admission, NT-pro-BNP expression 24 hours after admission and time from onset to hospital admission were independent prognostic factors for the prognosis. According to ROC curve, the area under curve of the NIHSS score 24 hours after admission was 0.686, that of NT-pro-BNP expression 24 hours after admission was 0.965, and that of time from onset to hospital admission was 0.832. Conclusion: In conclusion, the high NT-pro-BNP expression and NIHSS score indicate a severe condition and poor prognosis. The NIHSS score 24 hours after admission, NT-proBNP expression 24 hours after admission and time from onset to hospital admission are independent risk factors for the poor prognosis of elderly patients with AIS.
No . 10 / 2014 Fiscal Rules and Unemployment

This paper analyzes fiscal policy under fiscal rules in a New Keynesian model with search and matching frictions and distortionary taxation. The model is estimated with US data including detailed information on fiscal instruments. Several findings stand out. First, fiscal rules enhance the positive effects of discretionary fiscal policy on output and unemployment if they influence the expected future path of interest rates. However, effects are smaller as suggested in the existing literature. Second, spending and consumption tax cuts have the largest multipliers. Third, multipliers for labor tax cuts are small. These results originate from the labor market friction and persist in an economy where the friction is more severe. Demand side disturbances explain the majority of labor market dynamics.

Institutional and Actor-Network Theories of Accounting : Can They Be Combined ?

Intrigued by the emerging trend to combine IT and ANT in accounting research, we investigate whether or not the combination gives rise to paradigmatic tensions and if so, how scholars have dealt with such tensions in practice. Our analysis of the two method theories’ key paradigmatic premises suggests that there are several differences and tensions between them. The most significant tensions relate to the two method theories’ diverging ontological conceptions of the nature of social structures and agency and their very different epistemological views of the role of theory. Our review of extant accounting research combining IT and ANT indicates that in the majority of studies, these tensions have simply been ignored. This may be seen as a rather worrying lack of reflexivity on the challenges involved in mixing theories with distinct paradigmatic origins. If further rapprochement in the simultaneous employment of IT and ANT is considered useful, it is important to consider the asymmetry of the situation: Due to the particular paradigmatic premises of ANT, it is challenging to combine it with other method theories. Hence such rapprochement can only take place through an IT-based analysis incorporating elements from ANT, for instance by paying greater attention to materiality and non-human actors; assuming an issue-based view of organizational fields; and adopting a relational, dynamic perspective on power. The major implication of our study is the need for accounting researchers to practice greater reflexivity when considering the combination of two theoretical perspectives.
Have a chat with BERT ; passage re-ranking using conversational context

In this thesis, the problem of question answering using conversational context is explored for the Conversational Assistance Track of the Text REtrieval Conference. The goal of the task in this track is to provide an answer to a query by retrieving responses from a large set of short text passages and ranking these according to their computed relevance to the query. The state-of-the-art NLP model BERT [1] is compared to the baseline ranker BM25 [2]. It is researched how including conversational context in the input influences the predictive power of these models. Multiple methods for dealing with the input restrictions of the BERT model are compared; clipping, summarization and, rank and score fusion. This was evaluated on two datasets of a different nature; a dataset containing artificially generated conversational sessions and one containing handcrafted, more human-like sessions. The results show that BERT outperforms BM25 in all experiments, regardless if or how much context is taken into account. Adding conversational context to the input however does not increase predictive power in both models. Nonetheless, the context processing methods can still be compared; the fusion methods perform best. Additionally, it does not matter for the experiments in this works whether the data is constructed artificially or in a more realistic manner.

End-to-end congestion control algorithms for the Internet

The Transmission Control Protocol (TCP) has played a major role in the success of Internet. In particular TCP congestion control plays a critical role, which has ensured stability in an exponentially growing Internet. The classical approach to Internet congestion control is called the end-to-end approach. TCP sources adapt their congestion window using network signals, e.g., packet losses and delay variations. However, the advent of next-generation networks have shown the limitations of TCP’s conservative congestion control design, creating several challenges such as reduced link efficiency in heterogeneous networks. At the same time, mechanisms based on the routerassisted approach have also been proposed. Sources may use explicit information from routers in the network, achieving superior performance and solving many existing issues. Nonetheless, this strategy is still under discussion, as its implementation in the current Internet is challenging due to both technical and political aspects. More recently, researchers have proposed several high-speed end-to-end congestion control schemes. Virtually all proposals enable good efficiency, but they can create new problems, such as reduced fairness and increased network strain. In this work we propose and study new end-to-end mechanisms, incorporating them in a popular loss-based, high-speed, end-to-end algorithm. We obtained through simulation encouraging results, which means that, at least for the simulated network environments, it is possible to have reasonable end-to-end congestion control algorithms. At the same time, with these mechanisms, the complexity is transferred to the edge of the network and compatibility with existing TCP versions is maintained.
Shared Communication during the Professional Experience Program: A Distributed Leadership Perspective

This paper explores the concept of distributed leadership in the context of a teaching and learning project conducted at the Australian Catholic University (ACU), School of Education, McAuley Campus. In this context, distributed leadership is associated with building relationships that are authentic, genuine, caring, and empowering. Within this teaching and learning project, a website was developed, using the university’s Learning Management System (Blackboard), in order to facilitate multi-dimensional communication involving pre-service teachers, the university coordinator and their visiting supervisors. The topic of this communication was the pre-service teachers’ experience of teaching in school contexts as part of their Professional Experience Program (PEP). After the completion of their professional experience in schools, pre-service teachers completed a survey of their perceptions of the support provided through Blackboard. More than 50 percent of the pre-service teachers completed this online survey. The results describe the nature, extent, and type of relationships that can be established during this professional experience. It is particularly interesting that these results suggest the possibility of modelling distributed leadership to pre-service teachers in their teaching program. ; ;
Evaluation Of Pass By Noise Performance Of Passenger Car By Modified Muffler

The sound quality of any product plays an important role for its marketing and popularity. Here in this research we are trying to improve the sound quality of passenger car. So for the sound quality of car, we are trying to modify the exhaust system.In the exhaust system, are using baffle plate with perforation. Firstly we use single baffle with perforation and increase the baffle plate up to three baffle plates.This project deals with four different models of chambered exhaust muffler with perforation in baffles and concludes the best possible design for good sound quality. In this exhaust system along with baffles plate, we also use absorptive materials to improve the sound quality. Absorptive materials for this research we are using the glasswool and rockwool. For this research we have performed all the simulation in Ricardo wave build software. So after simulation in Ricardo wave build software, we conclude that the muffler with having three baffle plate along with rockwool as an apsorptive material give the best result as compare to other cases.
Do Creditor Control Rights Impact Corporate Tax Avoidance ? Evidence from Debt Covenant Violations

We examine the effect of bank interventions on corporate tax avoidance activities via the lens of debt covenant violations. Using three different identification strategies, we provide evidence that bank interventions have a negative effect on cooperate tax avoidance activities. This effect is persistent in the long run and less pronounced for financially constrained firms. Evidence also suggests an increase in tax avoidance activities leads to a relatively less increase in firm value for firms that violate covenants compared to matched firms that do not violate covenants. Our paper contributes to the debate on whether creditors perceive tax avoidance to be beneficial and highlights the subtle difference between creditor governance and shareholder governance.

An Evaluation of Recommendation Algorithms for Online Recipe Portals

Better models of food preferences are required to realise the oft touted potential of food recommenders to aid with the obesity crisis. Many of the food recommender evaluations in the literature have been performed with small convenience samples, which limits our conidence in the generalisability of the results. In this work we test a range of collaborative iltering (CF) and content-based (CB) re-commenders on a large dataset crawled from the web consisting of naturalistic user interaction data over a 15 year period. The results reveal strengths and limitations of diferent approaches. While CF approaches consistently outperform CB approaches when testing on the complete dataset, our experiments show that to improve on CF methods require a large number of users ( > 637 when sampling randomly). Moreover the results show diferent facets of recipe content to ofer utility. In particular one of the strongest content related features was a measure of health derived from guidelines from the UK Food Safety Agency. This inding underlines the challenges we face as a community to develop recommender algorithms, which improve the healthfulness of the food people choose to eat.
LEARNING AND TEACHING : THEORIES, APPROACHES AND MODELS

It is clear to everyone that social progress depends on individual development in this day and age, which is called information age, therefore, the importance given to the education of an individual has reached its peaking point. When it is considered that the quantity of the information produced in the last ten years is equal to the quantity of information produced from the beginning of the history of humanity until the last ten years, that half life of information has become shorter to a great extent and even that younger people know more about some subjects than elder people nowadays; the aims of education are determined automatically. The unique means of having a productive and democratic social structure equipped with information and technology, which has become the main aim of today’s states, is to realize educational principles that can turn the individual into the expected form. What is necessary for a democratic society is an individual who asks, questions, investigates, listens and respects; who is open to communication and interaction besides changes and developments; who is not conducted, directed or deceived; who uses information for a productive society; who dances with information and who can explore new information. And to realize all above, individuals who have developed thinking abilities are needed.
FURTHER RESULTS ON ASYMPTOTIC STABILITY OF LINEAR DISCRETE TIME DELAY AUTONOMOUS SYSTEMS

Our aim, in this communication, is to improve the existing results concerning asymptotic stability of a particular class of linear discrete time delay systems. In that sense, this paper offers a new sufficient condition for delay independent asymptotic stability of systems of the form x (k + 1) = A0x (k) + A1x (k − h). A methodology used here is based on Lyapunov approach. Numerical computations are presented for illustration and comparison with the previous results.
Do cognitive constraints drive second-language listeners’ attention to prosodic information in speech?

Can Chinese learners of English use prosodic cues, as native listeners do, to resolve syntactic ambiguity in spoken-language comprehension? This question was addressed with two speech perception tasks, one in which listeners were aware of potential ambiguity, and one in which they were unaware of the ambiguity. Accuracy scores showed that learners’ use of prosodic information in disambiguation depended on awareness of ambiguity. Without awareness, the listeners’ preference for one meaning over the other could not be reversed by the presence of prosodic cues; after receiving explicit information that there was ambiguity, however, listeners succeeded in identifying the intended utterance meaning by exploiting the available prosody. This result suggests that L2 learners’ often-reported failure to use prosodic information in listening should not be ascribed to inability to use such information, but may instead result from a deliberate choice to restrict levels of processing, in order to simplify the listening task.
Hedge funds and asset markets : tail or two-state dependence ? ∗

This paper tries to reconcile opposing evidence found in previous literature about the tail neutrality of Market Neutral Hedge Funds. In particular, we show that the existence of a common regime between hedge funds and the market index creates a non-linear dependence that can be confounded with tail dependence. This evidence is consistent with the Market Neutral Hedge Funds be affected by a common macroeconomic component as opposed to holding a portfolio subject to big losses in extremely rare events. We estimate a regime-switching copula model and we show with simulated data from our model that the tests conducted in Brown and Spitzer (2006) do not reject the tail dependence hypothesis, even if the tail dependence is set to zero. Moreover, we provide evidence of statistical and economically significant linear correlations in each regime. JEL classification: G11, G23.
Discontinuous Coverage in Medicaid and the Implications of 12-Month Continuous Coverage for Children. Cambridge, MA: Mathematica Policy Research

Examines the implications of continuous coverage for children using Medicaid enrollment and payment data for California, Michigan, Missouri, and New Jersey. Finds that discontinuity affects a small proportion of children who would qualify for continuous coverage and that some groups of children, such as older adolescents and Hispanics, are at higher risk of discontinuous coverage than others. Suggests that continuous coverage may be an important component of a state's efforts to eliminate health disparities across different segments of the population.
Connection between Two Leading Modes of Autumn Rainfall Interannual Variability in Southeast China and Two Types of ENSO-Like SSTA

The interannual variability of autumn rainfall in Southeast China (SEC) is significant, with two major modes, namely, monopole and dipole modes. It is found that the monopole mode is closely related to EP ENSO-like sea surface temperature anomaly (SSTA), and the dipole mode is related to CP ENSO-like SSTA. During the warm phase of EP ENSO-like SSTA, an anomalous anti-Walker circulation emerges in the tropical Pacific, with an anomalous subsiding during 110°E–120°E and an anomalous ascending branch in SEC. These two branches of anomalous current are in the same longitude and form a closed meridional circulation. Besides, there also exists an anticyclone anomaly in the Northwest Pacific (NWP), transporting water vapor into SEC. These circulation configurations induced by the warm phase of EP ENSO-like SSTA are consistent with those of monopole mode positive anomaly year. The good correspondence between EP ENSO warm event and the positive monopole mode also helps to support the corresponding relationship between the EP ENSO-like SSTA and monopole mode of SEC autumn rainfall. After the diagnosis of the perturbation omega equation, the anomalous subsiding branch over SEC, as the key link of EP ENSO-like warm phase SSTA exerting impact on the monopole mode during positive anomaly year, is mainly related with the anomalous relative vorticity advection transported by basic zonal wind and temperature advection transported by meridional wind anomaly. As for the dipole mode, it is related to the CP ENSO-like SSTA, but the corresponding relationship is weaker than that of the monopole mode and EP ENSO-like SSTA. In special, during the warm phase of CP ENSO-like SSTA, an anomalous cyclone appears in the NWP and prevailing sinking motion over SEC, both of which favors the appearance of positive anomaly of the dipole mode. Specially, the local anomalous vertical motion mainly depends on anomalous relative vorticity transported by basic meridional wind. Generally speaking, the monopole (dipole) mode is closely associated with the EP (CP) ENSO-like SSTA, demonstrating some correspondence.
[!] WHAT’S THE NAME OF IT? [!] : PHONETIC CLICKS IN WORD SEARCH STRATEGIES IN GLASGOW

Clicks are phonemically rare, non-pulmonic stop sounds [10]. They have also been reported as nonverbal features but few studies have identified English clicks’ phonetic form and functions [22, 15]. Despite the vast pragmatic literature on word search, knowledge of the phonetic form of word search clicks is mostly anecdotal. This paper reports results from an ongoing sociophonetic study, using a combination of Conversation Analysis to identify word searches [2] and narrow auditory transcription with visual spectral information in Praat to analyse clicks. In 8 hours of conversations of 16 Glaswegian speakers, we found 125 word searches, 55 with a click. Phonetically, clicks were oral, mainly dental in articulation, often alongside a particle (e.g. uh/um), and tended not to occur with creakiness or inbreaths. Mixed effects logistic regression analysis further suggests the greatest predictor of a click in a word search is the presence of a particle.
