Modelación de la cinemática del ventrículo izquierdo usando imágenes de resonancia magnética marcada

In recent years, cardiovascular illness have become one of the most frequent causes of death. To elaborate a sound diagnosis, and hence reduce its effects, it has become essential to have images to describe qualitatively the state of the human organs, including the heart. However, the interpretations of these images depends greatly on the physician skills which make it error prone and hence reduce the reliability of these interpretations. One of the techniques available in the area of cardiac imaging is the magnetic resonance. These images have the advantage of being non-invasive, giving the opportunity of studying living hearts, and hence are becoming very popular. Due to the stability of the magnetic resonance myocardium images, it is only possible to obtain global measures about it. On the contrary, tagged can be tracked down in time. Since these tags deform along the myocardium, its cinematic is equivalent to the heart one. These images are called tagged magnetic resonance images. In this thesis, we develop a method to model the left ventriculus cinematics based on tagged magnetic resonance image analysis. Our study includes: segmentation of the myocardium, tracking of the tags, 3-D modeling, and patients comparison. We describe in detail the method used to segment the myocardium. Also, we propose a novel technique to track the tags using Gabor filters using the tag pattern characteristic frequency. Our method to model the myocardium requires to estimate the deformation in the image planes, thus it is necessary to align them. Our study includes a method to solve the plane shift problem based on normalized mutual information along the intersection lines. We suggest a procedure to obtain the deformation vectors in 3-D from their combination in 2-D. Indeed, we develop and interpolation procedure to distribute the deformation on the short axis images. Later on, we show the results and the statistical studies for the myocardium rotation and torsion in a healthy population. Finally, we conclude discussing future lines of research
What Do the Items and Their Associations Refer to in a Network Approach to Personality?

It is hard to judge the potential usefulness of a network approach to personality research because Cramer et al. (2012) mix up applications to one individual, inter–individual differences and intra–individual processes. From each perspective, the network units, their associations and causal interpretations of such associations have a completely different meaning, and it depends on the particular perspective, the level of aggregation and whether one wants to model measurement error whether latent variables have a place in network models in personality research.

The Value of Emotional Intelligence for High Performance Coaching: A Commentary

INTRODUCTION In their article, Jonathan Chan and Clifford Mallett attempted to highlight the conceptual validity and the practical utility of the Emotional Intelligence (EI) construct for highperformance sport coaches. Due to a lack of extensive research on EI in sport settings, the authors contextualize management and workplace literatures to sport settings by using the Mayer and Salovey’s [1] four-branch model of EI (i.e., perceiving, using, understanding, and managing emotions). They also provide examples of how the proficiency in emotionregulation skills across these four areas of expertise might enhance the quality of coaching and the production of high performance. Thus the idea to introduce the main aspects of this research direction in sport seems quite appropriate. Several issues in the paper also provide a good basis for comments with a special emphasis on real emotional experiences in sport associated with emotion expertise.
Topic cache language model for speech recognition

Traditional n-gram language models suffer from insufficient long-distance information. The cache language model, which captures the dynamics of word occurrences in a cache, is feasible to compensate this weakness. This paper presents a new topic cache model for speech recognition based on the latent Dirichlet language model where the latent topic structure is explored from n-gram events and employed for word prediction. In particular, the long-distance topic information is continuously updated from the large-span historical words and dynamically incorporated in generating the topic mixtures through Bayesian learning. The topic cache language model does effectively characterize the unseen n-gram events and catch the topic cache for long-distance language modeling. In the experiments on Wall Street Journal corpus, the proposed method achieves better performance than baseline n-gram and the other related language models in terms of perplexity and recognition accuracy.
Development-assistance Strategies for Stroke in Low- and Middle-income Countries

While communicable diseases still pose a serious health threat in developing countries, previously neglected health issues caused by non-communicable diseases such as stroke are rapidly becoming a major burden to these countries. In this review we will discuss the features and current status of stroke in low- and middle-income countries (LMICs). Overall the global burden of hemorrhagic stroke is larger than ischemic stroke, with a disproportionately greater burden, measured in incidence and disability-adjusted life-years, regionally localized in LMICs. Patients in poorer countries suffer due to insufficient primary care needed to control risk factors such as hypertension, and inadequate emergency care systems through which sudden events should be managed. In light of these situations, we emphasize two strategic points for development assistance. First, assistance should be provided for bolstering, integrating, and coordinating both the primary health and emergency care systems, in order to prevent stroke and strengthen stroke management, respectively. Second, the assistance needs to focus on programs at the community level, to reduce life-style risks of stroke in a more sustainable manner, and to improve stroke outcomes more effectively.
Learning from Collective Intelligence in Groups

Collective intelligence, which aggregates the shared information from large crowds, is often negatively impacted by unreliable information sources with the low quality data. This becomes a barrier to the effective use of collective intelligence in a variety of applications. In order to address this issue, we propose a probabilistic model to jointly assess the reliability of sources and find the true data. We observe that different sources are often not independent of each other. Instead, sources are prone to be mutually influenced, which makes them dependent when sharing information with each other. High dependency between sources makes collective intelligence vulnerable to the overuse of redundant (and possibly incorrect) information from the dependent sources. Thus, we reveal the latent group structure among dependent sources, and aggregate the information at the group level rather than from individual sources directly. This can prevent the collective intelligence from being inappropriately dominated by dependent sources. We will also explicitly reveal the reliability of groups, and minimize the negative impacts of unreliable groups. Experimental results on real-world data sets show the effectiveness of the proposed approach with respect to existing algorithms.
The roles of time and ecology in the continental radiation of the Old World leaf warblers (Phylloscopus and Seicercus)

Many continental sister species are allopatric or parapatric, ecologically similar and long separated, of the order of millions of years. Sympatric, ecologically differentiated, species, are often even older. This raises the question of whether build-up of sympatric diversity generally follows a slow process of divergence in allopatry, initially without much ecological change. I review patterns of speciation among birds belonging to the continental Eurasian Old World leaf warblers (Phylloscopus and Seicercus). I consider speciation to be a three-stage process (range expansions, barriers to gene flow, reproductive isolation) and ask how ecological factors at each stage have contributed to speciation, both among allopatric/parapatric sister species and among those lineages that eventually led to currently sympatric species. I suggest that time is probably the critical factor that leads to reproductive isolation between sympatric species and that a strong connection between ecological divergence and reproductive isolation remains to be established. Besides reproductive isolation, ecological factors can affect range expansions (e.g. habitat tracking) and the formation of barriers (e.g. treeless areas are effective barriers for warblers). Ecological factors may often limit speciation on continents because range expansions are difficult in ‘ecologically full’ environments.
Nanocomputing: Small Devices, Large Dependability Challenges

Nanoscale digitization will be an essential lever to foster the emerging cyberphysical systems. Thanks to the widespread presence of IT and communication capabilities far beyond today's Internet and wireless networking capabilities, future highly pervasive embedded systems will feature smart objects (sensors and actuators) fully merged with the environment in which they're deployed. This will result in enhanced ambient services spanning the everyday life of citizens, thus improving our quality of life, increasing awareness of resources and the environment, and enriching the user experience.
Weight control, self-perception, and self-esteem in adolescence : the role of schools and social comparison

For adolescents, body weight can be a complicated and sometimes difficult issue. Though the majority of adolescents report being aware of normative gendered body ideals, how adolescents incorporate or reject these ideals into their own weight-control decisions or sense of self can vary dramatically, largely in reaction to their social experiences with body ideals in the local, immediate contexts of their daily lives. The role of one such local context schools has remained largely unexplored in existing literature. Using the National Longitudinal Study of Adolescent Health (Add Health) and multi-level modeling, I investigate the role high school weight cultures play in the development of adolescents’ weight-loss behaviors, overweight self-perceptions, and self-esteem. I employ social comparison theories, specifically the idea of who may serve as a likely target for social comparison general others, similar others, or high status others to develop hypotheses about which aspects of the school context may be associated with various aspects of adolescents’ body weight. Overall, my results indicate x that there is a strong relationship between adolescents’ weight-loss behavior, selfperception and self-esteem and the weight-related culture in the school. For example, adolescent boys, on average, are significantly less likely to report perceiving themselves as overweight or engaging in weight-loss behaviors when they attend schools where there are many overweight boys in the student body. I also find that there is some variation within the school in terms of which peers are most salient to adolescents’ behaviors and self-perceptions. Both boys and girls are particularly impacted by the values and behaviors of similar others, when similarity is defined by same-sex adolescents of a similar body size. For example, on average, overweight adolescent girls are significantly more likely to report engaging in weight-loss behaviors when a higher proportion of overweight girls in their school also are engaged in weight-loss behaviors. The same pattern is found among adolescent boys. Overall, these findings suggest that meso-level social contexts like schools may be particularly important to how individuals incorporate macro-level beliefs or values like gendered body ideals into their own behaviors and self-concepts.
Auditory ERPs to Stimulus Deviance in an Awake Chimpanzee (Pan troglodytes): Towards Hominid Cognitive Neurosciences

Background For decades, the chimpanzee, phylogenetically closest to humans, has been analyzed intensively in comparative cognitive studies. Other than the accumulation of behavioral data, the neural basis for cognitive processing in the chimpanzee remains to be clarified. To increase our knowledge on the evolutionary and neural basis of human cognition, comparative neurophysiological studies exploring endogenous neural activities in the awake state are needed. However, to date, such studies have rarely been reported in non-human hominid species, due to the practical difficulties in conducting non-invasive measurements on awake individuals. Methodology/Principal Findings We measured auditory event-related potentials (ERPs) of a fully awake chimpanzee, with reference to a well-documented component of human studies, namely mismatch negativity (MMN). In response to infrequent, deviant tones that were delivered in a uniform sound stream, a comparable ERP component could be detected as negative deflections in early latencies. Conclusions/Significance The present study reports the MMN-like component in a chimpanzee for the first time. In human studies, various ERP components, including MMN, are well-documented indicators of cognitive and neural processing. The results of the present study validate the use of non-invasive ERP measurements for studies on cognitive and neural processing in chimpanzees, and open the way for future studies comparing endogenous neural activities between humans and chimpanzees. This signifies an essential step in hominid cognitive neurosciences.
Clonidine Patch Ingestion in an Adult

OBJECTIVE: To report a case of deliberate ingestion of a clonidine hydrochloride patch in an adult. CASE SUMMARY: A patient at a psychiatric hospital with a diagnosis of major depression and polysubstance abuse was administered a clonidine patch for opiate detoxification. The patient subsequently chewed and swallowed the patch (total clonidine content: 5 mg); he was subsequently transferred to a nearby general medical hospital for management of obtundation and profound sinus bradycardia. DISCUSSION: The use of clonidine in withdrawal states is discussed. The primary adverse effects attributable to clonidine overdose, hypotension, and profound sinus bradycardia, may be managed symptomatically. Accidental ingestion of clonidine patches by infants and children has previously been reported in the literature. This is the first reported case of deliberate ingestion of a clonidine patch in an adult. CONCLUSIONS: Before initiating topical clonidine therapy for chemical withdrawal states, patients should be evaluated carefully for suicide potential and a history of previous suicide attempts. If a patient expresses suicidal ideation or has attempted suicide in the past, he is probably not a candidate for topical clonidine therapy in either the inpatient or outpatient setting.
The Virtual Classroom: Art Education for Itinerant Students

In Portugal, children deprived of a permanent residence (merchants and circus performers) grew accustomed to change school countless times, lived with discrimination from colleagues, with the impossibility of setting up roots and with a difficult progression in the access to knowledge. In 2005, an innovative project would change their school paths radically, throughout the creation of a custom-designed curriculum to help meet their individual needs: the Mobile School. In this inclusive school of b-learning, these children may now have teachers and colleagues who they can relate to and really feel like "their own" and who may follow them during at least one full school year. Without discrimination. With stability. With care. In this context, Art Education is part of a set of subjects which comprehends Visual Arts and Music, with a perspective towards learning through the implementation of projects using the ICT as a way of artistic expression. Communication between teachers and students is achieved through a virtual platform, and the artistic creations of these students are achieved mainly through specific software for drawing and image editing. Benefiting around 100 children, what will be the future of the Mobile School in a period not only of economic crisis but also claiming social inclusion as a way of developing integrated societies?
A Security Evaluation of DNSSEC with NSEC3

Domain Name System Security Extensions (DNSSEC) and Hashed Authenticated Denial of Existence (NSEC3) are slated for adoption by important parts of the DNS hierarchy, including the root zone, as a solution to vulnerabilities such as ”cache-poisoning” attacks. We study the security goals and operation of DNSSEC/NSEC3 using Mur’, a finite-state enumeration tool, to analyze security properties that may be relevant to various deployment scenarios. Our systematic study reveals several subtleties and potential pitfalls that can be avoided by proper configuration choices, including resource records that may remain valid after the expiration of relevant signatures and potential insertion of forged names into a DNSSEC-enabled domain via the opt-out option. We demonstrate the exploitability of DNSSEC opt-out options in an enterprise setting by constructing a browser cookie-stealing attack on a laboratory domain. Under recommended configuration settings, further Mur’ model checking finds no vulnerabilities within our threat model, suggesting that DNSSEC with NSEC3 provides significant security benefits.
Consumers' Responses To Reduced Personal Space In A Service Setting

This paper examines consumers’ responses to reduced personal space in a service setting. It describes two studies that investigate how users respond to restaurant tables spaced closely together. The first study evaluated consumers’ emotional responses to a projected dining experience when dining tables were spaced at one of three distances, and found that diners strongly object to closely spaced tables in the abstract. The second study tested responses to specific inter-table distances during actual dining experiences in a restaurant. Findings suggest that consumers in a real environment are less sensitive to reduced personal space than they are when asked about their feelings toward inter-table space before the service takes place. The results from this research will enhance the understanding of personal space preferences and behaviors in public spaces and may influence the design of service environments.
Why don't more student athletes study abroad?

This research focused on why student athletes tend to not studying abroad. Student athletes at the University of Wisconsin-Stout were asked to take a survey concerning why had they not gone abroad throughout their time on campus, what were the factors that prohibited them from going abroad, and whether they even wanted to go abroad. This study also looked at how many of those students were male and female, and how many sports they were involved in. Suggestions can be offered on what the international office could do better to make student athletes more aware of the programs offered for students who have a hard time going abroad because of the demands of their sport. The research concluded that there are multiple issues that affect the priority of going abroad such as cost, time, available opportunities, lack of awareness, and major alignment with current offerings for study abroad programs.

Quality of spirometry performed by 13,599 participants in the World Trade Center Worker and Volunteer Medical Screening Program.

OBJECTIVE To determine the ability of spirometry technicians in the World Trade Center Worker and Volunteer Medical Screening Program to meet American Thoracic Society spirometry quality goals. METHODS Spirometry technicians were trained centrally and performed spirometry sessions at 6 sites in the greater New York City area. We reviewed and graded the spirometry results for quality every month. RESULTS About 80% (range 70-88%) of the spirometry sessions met the American Thoracic Society spirometry goals. In general, the spirometry technicians with the most experience were more successful in meeting the quality goals. Participant characteristics explained very little of the quality variability. CONCLUSIONS The overall spirometry quality in this multicenter program was very good. Efforts to improve spirometry quality should focus on the performance of individual spirometry technicians.
Improvement in Total Sensing Time of the Receiver in the Cognitive Radio

This paper is emphasized on the total sensing time of the dedicated sensing receiver (DSR) of the cognitive radio (CR) network. To minimize the total sensing tine that is the time taken by the receiver to sense the spectrum, a potential modification has been made in the basic cognitive radio receiver architecture. The cognitive radio is a novel communication network, which is useful in utilizing the licensed spectrum by the unlicensed users when it is not being used by the licensed users. In order to reduce the sensing time of DSR, we have increased the number of antennas being used for DSR in the cognitive radio. The range of frequencies being utilized is increased to a large extent for various potential applications.
Cyclin CYB-3 controls both S-phase and mitosis and is asymmetrically distributed in the early C. elegans embryo

In early C. elegans embryos the timing of cell division is both invariant and developmentally regulated, yet how the cell cycle is controlled in the embryo and how cell cycle timing impacts early development remain important, unanswered questions. Here, I focus on the cyclin B3 ortholog CYB-3, and show that this cyclin has the unusual property of controlling both the timely progression through S-phase and mitotic entry, suggesting that CYB-3 is both an S-phase-promoting and mitosis-promoting factor. Furthermore, I find that CYB-3 is asymmetrically distributed in the two-cell embryo, such that the somatic precursor AB cell contains ∼2.5-fold more CYB-3 than its sister cell, the germline progenitor P1. CYB-3 is not only physically limited in P1 but also functionally limited, and this asymmetry is controlled by the par polarity network. These findings highlight the importance of the CYB-3 B3-type cyclin in cell cycle regulation in the early embryo and suggest that CYB-3 asymmetry helps establish the well-documented cell cycle asynchrony that occurs during cell division within the P-lineage. Highlighted article: CYB-3 cyclin controls both mitotic entry and S-phase entry in the one-cell embryo, while variations in the level of CYB-3 at the two-cell stage regulates asynchronous cell cycling.
