Preoperative Cardiac Evaluation and Management of the Patient Undergoing Major Vascular Surgery

About 313 million major surgical procedures are performed worldwide every year. Since the 1970s, vascular surgery has been identified as a subpopulation with disproportionately elevated risk. This risk persists today. For example, in the Vascular Events in Noncardiac Surgery Patients Cohort Evaluation (VISION) study of over 15,000 individuals undergoing major noncardiac surgery, vascular surgery was a predictor of 30-day mortality [adjusted hazard ratio (HR) = 2.38]. An analysis of about 123,500 cases in the National Surgical Quality Improvement Program (NSQIP) database from 2007 to 2010 revealed the absolute risk for death within 30 days after major vascular surgery to be 3%. Importantly, procedure-specific risks do vary considerably on the basis of the operative site, approach employed, and urgency of the procedure. An important reason for the elevated risk in vascular surgery patients is their burden of atherosclerotic disease. Many vascular surgical procedures address complications of peripheral arterial disease (PAD) or cerebrovascular disease (CVD). Atherosclerosis is the pathophysiological mechanism for both entities, as well as for coronary artery disease (CAD). Atherosclerosis involves plaques forming dense deposits in arterial walls and irreversibly expanding, subsequently leading to a
Checking Architectural and Implementation Constraints for Domain-Specific Component Frameworks Using Models

Software components are used in various application domains, and many component models and frameworks have been proposed to fulfill domain-specific requirements. The ad-hoc development of these component frameworks hampers the reuse of tools and abstractions across different frameworks. We believe that in order to promote the reuse of components within various domain contexts an homogeneous design approach is needed. A key requirement of such an approach is the definition and validation of reusable domain-specific constraints. In this paper we propose an extension to the Hulotte component framework that allows the definition and checking of domain-specific concerns. From the components' architecture to their implementations, concerns are defined and checked in an homogeneous manner. Our approach is illustrated and evaluated through the design of an example component-based application for the multitasking and distributed domains.
Effects of Radiation and free Convection Currents on Unsteady Couette Flow between two Vertical Parallel Plates with Constant Heat flux and Heat Source Through Porous Medium

The present study the free convection in unsteady Couette flow of a viscous incompressible fluid confined between two vertical parallel plates in the presence of thermal radiation with heat source in the presence of uniform magnetic field is presented. The flow is induced by means of Couette motion and free convection currents occurring as a result of application of constant heat flux on the wall with a uniform vertical motion in its own plane while constant temperature on the stationary wall. The fluid considered here is a gray, absorbing-emitting but non-scattering medium, and the Rosseland approximation is used to describe the radiative heat flux in the analysis. The dimensionless governing partial differential equations are solved by using regular perturbation technique. The results for the velocity, temperature and the skin-friction are shown graphically. The effects of different parameters are discussed.
Remote Operation of Mining Equipment Using Panoramic Display Systems: Exploring the Sense of Presence

The mining industry is interested in tele-operation systems to remove mining operators from hazardous or inconvenient environments while providing them with enough sensory information such that their efficiency is maintained or even enhanced. Similar systems are also used to provide collaboration and assistance in remote problem solving situations, including emergency scenarios. The increased availability of high-speed wired and wireless data networks is promoting the use of immersive environments, but there is not enough evidence yet to support whether such environments significantly improve the field-tested performance of tele-operation systems or not. We are interested in investigating a mixed-presence, tele-operation scenario involving an offsite operator remotely operating a robot as well as an onsite operator co-located with the robot. These scenarios are common in industry, yet poorly researched. We have conducted a trial to explore the effects of immersion on operator spatial awareness, sense of presence and satisfaction, in a mixed presence tele-operation scenario. This paper presents the results of our trial using a panoramic display system that provides some level of immersion. However, unlike virtual environments it provides an immersive view using video of a real remote space. The outcome of our work provides a first step in the exploration of cost effective technologies of potential value to the mining industry.
School's Out Forever: The Decline of Catholic Education in the United States

At their peak in the mid-20 th century Catholic schools in the United States enrolled twelve percent of the school-aged population. In 2010, they educated roughly five percent of school aged children. In the mid-1960s, there were over 13,000 Catholic schools in the United States. In 2010, they numbered fewer than 7,000, and projections suggest a sustained pattern of decline. This dissertation aims to document this dramatic change in the American educational landscape and offer explanations for the decline of this particular form of religious organization. Using extensive data from The Official Catholic Directory, the United States Census, and other secondary data sources, as well as archival documents and local newspaper accounts, I consider how demographic, organizational, and religious change have led to such dramatic declines in this key component of the private school sector in the United States. I argue that Catholic education in the United States has undergone a period of profound change that includes the breakdown of traditional organizational forms and patterns of behavior, the dislodging of belief systems, and the dismantling of governance structures dominant in earlier periods. I suggest that given previous literature that argues Catholic schools benefit urban minority students and students whose parents have low education, these changes have potentially important consequences for educational inequality in America.
Motivational Interviewing:Strategies for Increasing Retention in foreign Language Classrooms

Foreign language learning depends on the motivation of students. We aimed at augmenting the intrinsic motivation using motivational interviewing (MI) technique based on the trans-theoretical model of change. Engaging, focusing, evoking and planning were the underlying rationales in this technique that focused on developing a therapeutic relationship with teacher and engage in collaborative decision making. From January 2013 to December 2013, we developed and field-tested this technique in a private language institute in South India. Between July 2014 and December 2014, the strategy was tested in French (N=20, Males=12, Females=8) and Spanish(N=31, Male=14; Females=17). The technique focused on group and individual interviewing during the 100-hour class (baseline, midline and end-line). Individual interviews to ascertain the motivation levels and the value attached to the language were done at the beginning of the course followed by mid line group and individual motivational interviewing. The motivation levels were examined at the end line individual interviewing after the course based on the desire to continue to next level. The attrition rate of the students was measured. Field notes were also collected and qualitatively analyzed. Results revealed that students developed more confidence with higher retention rates (attrition less than 5%). Motivation in foreign language learning can be increased using motivational interviewing. Language teachers can integrate this technique in their classrooms. The long term implications in learning require exploration.
Spatial isolation and genetic differentiation in naturally fragmented plant populations of the Swiss Alps

Aims The effect Of anthropogenic landscape fragmentation on the genetic diversity and adaptive potential of plant populations is a major issue in conservation biology. However, little is known about the partitioning of genetic diversity in alpine species, which occur in naturally fragmented habitats. Here, we, investigate molecular patterns of three alpine plants (Epilobium fleischeri, Geum reptans and Campanula thyrsoides) across Switzerland and ask whether Spatial isolation has led to high levels of populations differentiation, increasing over distance, and a decrease of within-population variability. We further hypothesize that file contrasting potential for long-distance dispersal (LDD) of Seed in these Species will considerably influence and explain diversity partitioning. Methods For each study species, we Sampled 20-23 individuals from each of 20-32 populations across entire Switzerland. We applied Random Amplified Polymorphic Dimorphism markers to assess genetic diversity within (Nei's expected heterozygosity, H-e; percentage of polymorphic hands, P-P) and among (analysis of molecular variance, Phi(st)) populations and correlated population size and altitude with within-populalion diversity. Spatial patterns of genetic relatedness were investigated using Mantel tests and standardized major axis regression as well as unweighted pair group method with arithmetic mean cluster analyses and Monmonier's algorithm. To avoid known biases, We standardized the numbers of populations, individuals and markers using multiple random reductions. We modelled LDD with a high alpine wind data set using the terminal velocity and height of seed release as key parameters. Additionally, we assessed a number of important life-history traits and factors that potentially influence genetic diversity partitioning (e.g. breeding system, longevity and population size). Important findings For all three species, We found a significant isolation-by-distance relationship but only a moderately high differentiation among populations (Phi(st): 22.7, 48 and 16.8%, for E. fleischeri, G. reptans and C. thyrsoides, respectively). Within-population diversity (H-c: 0.19-0.21, P-p: 62-75%) was not reduced in comparison to known results from lowland species and even small populations with < 50 reproductive individuals contained high levels of genetic diversity. We further found no indication that a high long-distance seed dispersal potential enhances genetic connectivity among populations. Gene flow seems to have a strong stochastic component causing large dissimilarity between population pairs irrespective of the spatial distance. Our results suggest that other life-history traits, especially the breeding System, may play an important role in genetic diversity partitioning. We conclude that spatial isolation in the alpine environment has a strong influence on population relatedness but that a number of factors can considerably influence the strength of this relationship.
Encoding order and developmental dyslexia: A family of skills predicting different orthographic components

We investigated order encoding in developmental dyslexia using a task that presented nonalphanumeric visual characters either simultaneously or sequentially—to tap spatial and temporal order encoding, respectively—and asked participants to reproduce their order. Dyslexic participants performed poorly in the sequential condition, but normally in the simultaneous condition, except for positions most susceptible to interference. These results are novel in demonstrating a selective difficulty with temporal order encoding in a dyslexic group. We also tested the associations between our order reconstruction tasks and: (a) lexical learning and phonological tasks; and (b) different reading and spelling tasks. Correlations were extensive when the whole group of participants was considered together. When dyslexics and controls were considered separately, different patterns of association emerged between orthographic tasks on the one side and tasks tapping order encoding, phonological processing, and written learning on the other. These results indicate that different skills support different aspects of orthographic processing and are impaired to different degrees in individuals with dyslexia. Therefore, developmental dyslexia is not caused by a single impairment, but by a family of deficits loosely related to difficulties with order. Understanding the contribution of these different deficits will be crucial to deepen our understanding of this disorder.
CHARACTER VARIETY OF REPRESENTATIONS OF A FINITELY GENERATED GROUP IN SL2

This is a partial exposition of [S4, S5, S6], which study the space of representations of a (finitely generated) group Γ in SL2 and GL2 in an attempt of its application in geometry: Teichmüller spaces, knot theory, hyperbolic manifolds, moduli spaces, · · · , etc. (see for instance, [A], [Be], [Br], [C-C-G-L-S], [C-S], [F-K], [G], [H], [H-L-M], [H-K], [J-W], [K], [Kj], [Ko], [Kr], [Ma], [Mu], [N-Z], [O], [S], [S-S], [T], [W], [We], [Wo], [Y], · · · , etc). For simplicity, we omit the case for GL2 in the present exposition. Let us explain the main result of the present paper. Let Γ be a group. The purpose of the present paper is to introduce the character variety Ch(Γ, SL2) in order to parameterize conjugacy classes of representations of Γ in SL2 in a functorial way. At first, the character variety is introduced as a scheme over Z, independent of the coefficient ring of representations in question. Then, the scaler field is specialized to R to obtain results on representations in SL2(R) and in SU(2) with respect to the classical topology. Let us explain this briefly. Let Hom(Γ, SLn) be the functor R ∈ {commutative rings with 1} 7→ Hom(Γ, SLn(R)) ∈ {sets}. The functor is representable (see §1.3 Lemma) and so, for an abuse of notation, we denote by the same Hom(Γ, SLn) the scheme over Z representing the functor. The group scheme PGLn acts on Hom(Γ, SLn). Whether the universal categorical quotient Hom(Γ, SLn)//PGLn (Mumford [Mu1]) defined over Z exists or not seems to be a hard and unsolved question. Instead of asking directly for the quotient space, we introduce i) the character variety Ch(Γ, SL2) together with its discriminant subvariety DΓ as schemes over Z abstractly, and ii) the PGL2-invariant morphism πΓ : Hom(Γ, SL2) → Ch(Γ, SL2), for which we prove that i) the restriction of πΓ on the complement of π −1 Γ (DΓ) is a principal PGL2-bundle with respect to the etal topology, and ii) the inverse image π Γ (DΓ) is a subfunctor of Hom(Γ, SL2) consisting of abelian or reducible representations. This implies that the complement Hom(Γ, SL2) := Hom(Γ, SL2)\π (DΓ) consists of absolutely irreducible representations, and that Hom(Γ, SL2) has the universal categorical quotient space Ch(Γ, SL2) := Ch(Γ, SL2)\DΓ defined over Z. Then the result is specialized
A Dedicated Monitoring Infrastructure for Multicore Processors

On-chip monitoring of environmental information, such as temperature, voltage, and error data, is becoming increasingly important. To address this need, a low-overhead architectural approach to monitor data collection and use in multicore systems is described. A key aspect of our standalone monitoring subsystem is a low-complexity, on-chip network designed to transport monitor data with multiple priority levels. Collected monitor information is evaluated by a dedicated processor. Experimental results using architectural and interconnect simulators show that the new low-overhead subsystem facilitates employment of thermal and delay-aware dynamic voltage and frequency scaling. In contrast to using existing on-chip interconnect resources to communicate monitor data, the new subsystem provides necessary bandwidth for monitor data traffic without impacting application data traffic. Synthesis results show that our dedicated monitoring approach consumes about 0.2% of multicore area and power resources for an 8-core system based on AMD Athlon 64 processor cores.
Book Review: Johan F Hoorn, Creative Confluence

Warner analyses this potentially aberrant response by combining speech act theory and politeness theory to show how what may be conceived as a face threatening act was in fact an assertion of her legitimacy as an author. Warner also makes the point that ‘the decision to publish the piece . can also be seen as an attempt to redress what may have been an inadvertent threat to the author’s face’ (p. 208). In their Introduction, Chapman and Clark assume both that ‘ideas from pragmatics could potentially play a role in adjudicating between competing [literary] interpretations’ (p. 7) and that ‘specific approaches . should be those which seem to provide insights into the specific phenomena being considered. ’(p. 7) I fully endorse both these claims but also believe that they generously open the door to any field of literary study that provides ‘insights into the phenomena being considered. ’ Literary critiques – whether neo-historicist, feminist, cultural materialist, gay theorist or stylistic – can only be as robust as the theories that underlie them and, to the extent that the theories are robust, all such approaches will offer equally valuable insights. Sadly, I have not had the space to review all the chapters in this excellent volume. However, based on the evidence offered here, and in spite of some of my carping, there is no question but that pragmatic literary stylistics is in robust health and can contribute important insights of its own.
Admission Hyperglycemia Predicts a Worse Outcome in Stroke Patients Treated With Intravenous Thrombolysis

OBJECTIVE Admission hyperglycemia has been associated with worse outcomes in ischemic stroke. We hypothesized that hyperglycemia (glucose >8.0 mmol/l) in the hyperacute phase would be independently associated with increased mortality, symptomatic intracerebral hemorrhage (SICH), and poor functional status at 90 days in stroke patients treated with intravenous tissue plasminogen activator (IV-tPA). RESEARCH DESIGN AND METHODS Using data from the prospective, multicenter Canadian Alteplase for Stroke Effectiveness Study (CASES), the association between admission glucose >8.0 mmol/l and mortality, SICH, and poor functional status at 90 days (modified Rankin Scale >1) was examined. Similar analyses examining glucose as a continuous measure were conducted. RESULTS Of 1,098 patients, 296 (27%) had admission hyperglycemia, including 18% of those without diabetes and 70% of those with diabetes. After multivariable logistic regression, admission hyperglycemia was found to be independently associated with increased risk of death (adjusted risk ratio 1.5 [95% CI 1.2–1.9]), SICH (1.69 [0.95–3.00]), and a decreased probability of a favorable outcome at 90 days (0.7 [0.5–0.9]). An incremental risk of death and SICH and unfavorable 90-day outcomes was observed with increasing admission glucose. This observation held true for patients with and without diabetes. CONCLUSIONS In this cohort of IV-tPA–treated stroke patients, admission hyperglycemia was independently associated with increased risk of death, SICH, and poor functional status at 90 days. Treatment trials continue to be urgently needed to determine whether this is a modifiable risk factor for poor outcome.
Information technology Distributed embedded system for communication based on ant colony optimization algorithm

In this paper, a new UML-based distributed embedded system is prompted for communication based on ant colony optimization algorithm to solve the problem of low efficiency, error and delay in communication system. A described model is suitable for the communication of hardware and software co-design of distributed embedded system. This model, unlike well-suited for procedural specifications, is a dataflow model. Based on ant colony optimization algorithm, an algorithm is implemented in C++ and performed experiments on several examples. Communication delay is detailed analyzed under interaction of computation and communication. The model is not limited to network designs. Rather, it is aimed at modeling the general class of distributed embedded systems. The experiment shows that new system can achieve better performance.
Dual-decoder-model scheduling for H.264 video transmission over wireless networks

In this paper, a dual-decoder-based scheduling algorithm is proposed for H.264 video transmission over wireless networks. In the algorithm, the packet is scheduled by the packet quality contribution index (PQCI). The PQCI is defined and estimated not only by the quality distortion made for the current frame, but also by that made for the frames which directly or indirectly related with the current frame. A dual-decoder-model algorithm is proposed for the PQCI estimation. A novel architecture with two simulated decoders in the sender is developed. The simulations show that the proposed algorithm significantly outperforms the conventional methods in terms of received video qualities.
A Formal Condition to Stop an Incremental Automatic Functional Diagnosis

iAF2D (incremental Automatic Functional Fault Detective) is a methodology for the identification of the faulty component in a complex system using data collected from a test session. It is an incremental approach based on a Bayesian Belief Network, where the model of the system under analysis is extracted from a faulty signature description. iAF2D reduces time, cost and efforts during the diagnostic phase by implementing a step-by-step selection of the tests to be executed from the set of available tests. This paper focuses on the evolution of the BBN nodes probabilities, to define a stop criterion to interrupt the diagnosis process when additional test outcomes would not provide further useful information for identifying the faulty candidate. Methodology validation is performed on a set of experimental results.
Efficient handoff algorithm for inbound mobility in hierarchical macro/femto cell networks

To improve indoor coverage and network capacity, the use of hierarchical macro/femto cell networks is regarded as the most promising approach. We present an efficient handoff algorithm to support the inbound mobility from macro cells to femto cells under the consideration of large asymmetry in the transmit power of the cells. Numerical analysis reveals that the proposed algorithm yields a higher probability that the user will be correctly assigned to the femto cell while maintaining the number of handoffs at the same level.
