Minimal design strategy for embodied communication agents

The design of communication robots remains a relatively underdeveloped field. Such robots are often designed on a trial-and-error basis. Also, the shape of a robot heavily depends on the personal experience of a designer. In this paper, we discuss a method of designing long-term communication robots, which we call "minimal design. " It is unlike other industrial robot design methods. We have already produced some such communication robots, and here we provide explanations of them. Furthermore, we take our robots as examples of ideal communication robot design, we introduce our recent field observations. Finally, we illustrate by example a new idea for designing robot faces that is very different to conventional methods: it is based on a projected face easily produced using computer graphics. Some actuators are also included. This combination of light projection and conventional actuators in our proposed robot is the result of advances in robotics and screen agents.
Management of Bone Loss Associated with Recurrent Anterior Glenohumeral Instability

The diagnosis and treatment of osseous deficiencies associated with anterior shoulder instability have been a challenge to physicians for centuries. Whereas historical goals centered on the stable reduction and prevention of recurrent dislocation, current standards of success are predicated on the restoration of motion and strength and the return to functional activities, including competitive athletics. Reestablishment of anterior shoulder stability thus requires the recognition of osseous defects of the humeral head and glenoid, as well as a thorough understanding of the available treatment options in the context of a disciplined treatment algorithm. Although many surgical procedures have been described for the management of osseous deficiencies in association with anterior shoulder instability, in the authors’ experience, such procedures are seldom necessary. The purpose of this summary is to review treatment options as well as indications and techniques to address these bony deficiencies.
Complex and segmental uniparental disomy updated

Objective: To review all cases with segmental and/or complex uniparental disomy (UPD) and to discuss the impact of these cases on medical genetics. Design: Searching for published reports in PubMed and in the abstract books of the annual meetings of the American Society of Human Genetics and the European Society of Human Genetics up to March 2008. Results: In total, 26 cases with segmental UPD and a normal karyotype, 38 cases with UPD of a whole chromosome and a simple reciprocal or non-homologous Robertsonian translocation, four cases each with two isochromosomes and UPD of the short arm isochromosome and opposite UPD of the long arm isochromosome, three cases with UPD and an isochromosome of the short arm and the long arm of a metacentric or a submetacentric chromosome, one case with maternal UPD and an isochromosome 8 associated with a homozygous deletion (8)(p23.3pter), 42 cases with UPD and an isochromosome of the long arm of an acrocentric chromosome, 33 cases with UPD and a supernumerary marker or ring chromosome, 17 cases with UPD of a whole or parts of a chromosome and a complex karyotype, 13 cases with most likely mosaicism for genome wide paternal UPD, and three cases with most likely mosaicism for genome wide maternal UPD were found. Conclusion: This update shows that, in particular, the number of reported cases with segmental UPD or UPD associated with a marker chromosome clearly increased within the last few years, and that the investigation of both parents in cases with homozygosity of an autosomal recessively inherited mutation in some cases might help improve genetic counselling, resulting in a reduced recurrence risk in the case of UPD. Moreover, cases with segmental or complex UPD show that meiosis and early postzygotic mitoses seem to be more complex events than previously thought. For the formation of all kinds of segmental or complex UPD or genome wide UPD mosaicism, always a fortunate co-occurrence of meiotic or mitotic recombination, abnormal segregation, and subsequent correction are necessary. No case of recurrence has been reported until now. Therefore, in subsequent pregnancies invasive prenatal diagnosis is not necessarily indicated.
COP-SLAM: Closed-Form Online Pose-Chain Optimization for Visual SLAM

In this paper, we analyze and extend the recently proposed closed-form online pose-chain simultaneous localization and mapping (SLAM) algorithm. Pose-chains are a specific type of extremely sparse pose-graphs and a product of contemporary SLAM front-ends, which perform accurate visual odometry and reliable appearance-based loop detection. They are relevant for challenging robotic applications in large-scale 3-D environments for which frequent loop detection is not desired or not possible. Closed-form online pose-chain SLAM efficiently and accurately optimizes pose-chains by exploiting their Lie group structure. The convergence and optimality properties of this solution are discussed in detail and are compared against state-of-the-art iterative methods. We also provide a novel solution space, that of similarity transforms, which has not been considered earlier for the proposed algorithm. This allows for closed-form optimization of pose-chains that exhibit scale drift, which is important to monocular SLAM systems. On the basis of extensive experiments, specifically targeting 3-D pose-chains and using a total of 60 km of challenging binocular and monocular data, it is shown that the accuracy obtained by closed-form online pose-chain SLAM is comparable with that of state-of-the-art iterative methods, while the time it needs to compute its solution is orders of magnitudes lower. This novel SLAM technique thereby is relevant to a broad range of robotic applications and computational platforms.
V.O2 Kinetics and Clinical Factors Among Patients With Peripheral Artery Disease

PURPOSE: To investigate the association between oxygen uptake ( O2) kinetics and demographic, behavioral, and clinical factors among patients with peripheral artery disease (PAD). METHODS: A total of 85 PAD patients with intermittent claudication performed a constant load treadmill test, and breath-by-breath O2 was obtained to assess O2 kinetics. Demographic information, anthropometry, cardiovascular risk factors, and comorbid conditions were recorded. RESULTS: Using univariate analyses, higher values of tau ([&tgr;], ie, slowed O2 kinetics) were associated with female gender, non-Caucasian race, hypertension, dyslipidemia, and age ⩽66 years. Smoking, diabetes, obesity, metabolic syndrome, height, and ankle brachial index were not significantly related to O2 kinetics. Using multiple regression procedures, the identified predictors of slowed O2 kinetics were female gender (4.76 [95% CI: 1.49-8.03] seconds; P = .0049), non-Caucasian race (4.70 [95% CI: 1.29-8.12] seconds; P = .0075), hypertension (12.06 [95% CI: 8.83-15.28] seconds; P < .0001), and age ⩽66 years (4.97 [95% CI: 1.95-7.99] seconds; P = .0015). CONCLUSIONS: In PAD patients, slowed O2 kinetics are associated with demographic and clinical factors. The clinical significance is that female, non-Caucasian, and hypertensive PAD patients present central and/or peripheral limitations that may partially account for their walking impairment.
Psychological Inquiry: An International Journal for the Advancement of Psychological Theory

Summary and Conclusions The summarized research provides evidence thatperson characteristics moderate the impact of mediacharacteristics on social inﬂuence, knowledge shar-ing, and the outcomes of Internet search. In somecases—suchastheimpactofthesalientlevelofidentityon social inﬂuence in anonymous (vs. nonanonymous)communication—the person characteristics even havethe power to reverse the effect of a media characteris-tic. Hence, not considering these person variables canobviously lead to wrong conclusions.Across the three phenomena covered here, the keymedia characteristics are (a) less social cues duringcommunication(resultinginlessattentiontoothersandmore attention to the self), (b) self-guidance of onlinebehavior (resulting in stronger inﬂuences of individu-als’ own agenda), and (c) assisting cues provided bytools to guide users (e.g., knowledge awareness toolsor classiﬁcations of search engine results). This listis by no means comprehensive. The attentive readermight have noted that social cues and self-guidanceare characteristics of the web (i.e., across web appli-cations, e.g., social network sites, chats, wikis etc.),whereas assisting cues are implemented in a speciﬁcapplication, namely, information search. Such speciﬁcmedia characteristics exist in many web applicationsas communication science and human computer inter-action research have found (e.g., Treem & Leonardi,2013). Their analyses provide good starting points forpsychological research on the impact of the web (e.g.,recommender systems; Schwind & Buder, 2012). On the side of the
Evaluating an icon of population persistence: the Devil's Hole pupfish

The Devil's Hole pupfish Cyprinodon diabolis has iconic status among conservation biologists because it is one of the World's most vulnerable species. Furthermore, C. diabolis is the most widely cited example of a persistent, small, isolated vertebrate population; a chronic exception to the rule that small populations do not persist long in isolation. It is widely asserted that this species has persisted in small numbers (less than 400 adults) for 10 000–20 000 years, but this assertion has never been evaluated. Here, we analyse the time series of count data for this species, and we estimate time to coalescence from microsatellite data to evaluate this hypothesis. We conclude that mean time to extinction is approximately 360–2900 years (median 410–1800), with less than a 2.1% probability of persisting 10 000 years. Median times to coalescence varied from 217 to 2530 years, but all five approximations had wide credible intervals. Our analyses suggest that Devil's Hole pupfish colonized this pool well after the Pleistocene Lakes receded, probably within the last few hundred to few thousand years; this could have occurred through human intervention.
Ieee Computer Graphics and Applications 47 3d Freehand Gestural Navigation for Interactive Public Displays the Quantitative Experiment

T he increasing use of large public displays in indoor and outdoor environments brings new requirements and opportunities for rich, engaging user experiences. There are many ways to interact with displays, such as with a keyboard and mouse or a touch surface. 1 (For a look at other research on large interactive displays, see the related sidebar.) However, these devices are installed together with or close to the displays, so they're often unsuitable for public displays. Such situations include displays in enclosed spaces or out of users' reach, or large public displays intended to be viewed from a distance (see Figure 1). Another way to interact with displays is through mobile devices. However, connecting the devices to the displays normally requires specific configurations , so this approach might not be convenient or appropriate for users in public settings. Gestural input is becoming increasingly popular, including both gestural input using hands-on devices (for example, the Wii Remote) and freehand gestural input using camera-based motion tracking (for example, Microsoft Kinect). As gestural input increases beyond the now common home-gaming setting, freehand gestural interaction, which doesn't require hands-on input devices, will likely become more important for interactive public displays. In addition, with improvements in the ability to visualize urban environments in 3D, some applications , such as virtual tours of a historic site or navigation around a planned plaza, can benefit from 3D user interfaces and a more immersive user experience. However, most established interaction techniques are in 2D, so they might be unsuitable for these scenarios. Here, we focus on using freehand gestures to navigate 3D visualizations. We designed gestural techniques and evaluated them in a formal, quantitative lab experiment and a more informal qualitative field study. The results have led us to several design lessons for freehand gestural navigation on large public displays. This experiment used gestural navigation to search a visualization of a 3D urban environment. To gain further insight into gestural navigation's characteristics , we also compared it to keyboard-and-mouse navigation. Design Given our aim to use low-cost technology for freehand ges-tural interaction without users holding or wearing a device or fiducial marker, tracking small finger or wrist movements (for example, using a Kinect camera) would have been difficult. So, we used the acceleration or movement of larger body parts such as the hand or shoulder to control navigation. Controlling movement. Previous navigation techniques with tracking devices provide valuable …
Systemic inflammatory response syndrome after acute myocardial infarction complicated by cardiogenic shock.

BACKGROUND The role of inflammation in patients with coronary artery disease is emerging. We sought to assess the profile and outcomes of patients with a clinical syndrome of severe systemic inflammation that led to a diagnosis of suspected sepsis in the setting of acute myocardial infarction complicated by cardiogenic shock (CS). METHODS Patients enrolled in the randomized SHOCK (SHould we emergently revascularize Occluded Coronaries for cardiogenic shocK) trial (n = 302) were divided into those with clinical signs of severe systemic inflammation (eg, fever [94%] or leukocytosis [72%]) that led to a diagnosis of suspected sepsis (n = 54 [18%]) and those without suspected sepsis (controls; n = 243 [80%]). The patients with suspected sepsis were then further subdivided into those who were considered to be potentially infectious (positive culture result ["culture-positive"]; n = 40) and those who were not (negative culture result ["culture-negative"]; n = 14). RESULTS Severe systemic inflammation was diagnosed 4 and 2 days after the onset of CS in culture-positive and culture-negative patients, respectively. Patients who developed systemic inflammation tended to be younger (P = .05) and to have lower systemic vascular resistance (SVR) near the onset of CS (P = .006). Many culture-positive patients (40%) had undergone coronary artery bypass graft surgery. However, the lower the initial SVR, the higher the risk of developing culture-positive systemic inflammation (P = .01), even after controlling for age and coronary artery bypass graft surgery. A time-dependent model, adjusted for age, showed that culture-positive patients were at significantly higher risk for death than were controls (hazard ratio, 2.22; 95% confidence interval, 1.32-3.76; P = .008). CONCLUSIONS Almost one fifth of patients with acute myocardial infarction complicated by CS showed clinical signs of severe systemic inflammation, and those who were culture-positive for sepsis had twice the risk of death. The observation of lower SVR at the onset of shock in patients who subsequently had culture-positive systemic inflammation suggests that inappropriate vasodilation may play an important role in the pathogenesis and persistence of shock and in the risk of infection.
Genetic characterization of hadad, a mutant disrupting female gametogenesis in Arabidopsis thaliana.

The plant life cycle alternates between a diploid and a haploid generation, the spore-producing sporophyte and the gamete-producing gametophyte. Unlike in animals, where meiotic products differentiate directly into gametes, the haploid spores of plants divide mitotically to form a multicellular haploid organism. The differentiation of gametes occurs later in the development of the gametophyte.
FAT based adaptive controller design for pressure-sensor free pneumatic servo systems

Control of pneumatic servo systems is well-known to be challenge due to highly nonlinearities in the actuator dynamics and compressibility of the media. Most state feedback based strategies for the pneumatic servo systems require full state feedback to stabilize the closed loop system which implies the need for pressure measurements of the cylinder. Many researchers used state observers to complete the controller design without using actual pressure sensor feedback. In this paper, a transformation is suggested to reformulate the dynamic equation so that the pressure sensor feedback can be avoided without deteriorate the closed loop performance. A function approximation technique (FAT) based adaptive multiple-surface sliding controller (AMSSC) is also proposed for the closed loop stabilization. The multiple-surface sliding control is a backstepping-like design which is used to cope with the mismatched structure of the uncertainties, while the time-varying nature of the uncertainties is handled by the FAT. The closed-loop system is proved to be uniformly ultimately bounded by using the Lyapunov stability method. Experimental results demonstrate the effectiveness of the proposed design.
Sparse blind source separation for partially correlated sources

Blind source separation (BSS) is a very popular technique to analyze data which can be modeled as linear mixtures of elementary sources. Standard approaches generally make the assumption that such sources are statistically independent or at least uncorrelated. However, this is barely the case for real-world sources which are very often partially correlated. We present a new sparsity-enforcing BSS method coined Adaptive Morphological Component Analysis (AMCA) designed to retrieve sparse and partially correlated sources based on an adaptive weighting scheme. Numerical experiments have been carried out which show that the proposed method is robust to the partial correlation of the sources while standard BSS techniques fail. The performances of the proposed algorithm are further illustrated with simulations in the context of astrophysics.
AVALIAÇÃO DO ESTOQUE DE LAGOSTA VERMELHA Panulirus argus NA COSTA BRASILEIRA

O estudo trata da avaliação de estoque de lagosta vermelha Panulirus argus, recurso pesqueiro de considerável importância econômica na costa brasileira. As análises foram conduzidas com a utilização da Análise Sequencial de Populações, baseada na composição das capturas por idade, obtida a partir de dados de exportação por tipo comercial, amostras biológicas realizadas em empresas de pesca dos principais estados produtores e captura e esforço de pesca estimado para o período de 2005 a 2015. Os resultados indicam que, apesar das elevadas taxas de mortalidades por pesca e do comprometimento da estrutura por idade/comprimento da população, o estoque apresenta certa estabilidade quanto à sua composição em número e biomassa. A biomassa reprodutiva estimada, no entanto, se encontra bastante reduzida, com uma média 18% da biomassa sem pesca. Uma redução da mortalidade por pesca, especialmente sobre os indivíduos nas idades 4 e 5, seria fundamental para recuperar a estrutura da população e poderia resultar em melhores rendimentos da pescaria. Há indícios de resultados positivos neste sentido, a partir das medidas de ordenamento adotadas nos últimos 10 anos, que resultou em considerável diminuição do esforço de pesca.
Oral Microbiota Distinguishes Acute Lymphoblastic Leukemia Pediatric Hosts from Healthy Populations

In leukemia, oral manifestations indicate aberrations in oral microbiota. Microbiota structure is determined by both host and environmental factors. In human hosts, how health status shapes the composition of oral microbiota is largely unknown. Taking advantage of advances in high-throughput sequencing, we compared the composition of supragingival plaque microbiota of acute lymphoblastic leukemia (ALL) pediatric patients with healthy controls. The oral microbiota of leukemia patients had lower richness and less diversity compared to healthy controls. Microbial samples clustered into two major groups, one of ALL patients and another of healthy children, with different structure and composition. Abundance changes of certain taxa including the Phylum Firmicutes, the Class Bacilli, the Order Lactobacillales, the Family Aerococcaceae and Carnobacteriaceae, as well as the Genus Abiotrophia and Granulicatella were associated with leukemia status. ALL patients demonstrated a structural imbalance of the oral microbiota, characterized by reduced diversity and abundance alterations, possibly involved in systemic infections, indicating the importance of immune status in shaping the structure of oral microbiota.
Engineering AgentSpeak(L): A Formal Computational Model

Perhaps the most successful agent architectures, and certainly the best known, are those based on the Belief-Desire-Intention (BDI) framework. Despite the wealth of research that has accumulated on both formal and practical aspects of this framework, however, there remains a gap between the formal models and the implemented systems. In this paper, we build on earlier work by Rao aimed at narrowing this gap, by developing a strongly-typed, formal, yet computational model of the BDI-based AgentSpeak(L) language. AgentSpeak(L) is a programming language, based on the Procedural Reasoning System (PRS) and the Distributed Multi-Agent Reasoning System (dMARS), which determines the behaviour of the agents it implements. In developing the model, we add to Rao's work, identify some omissions, and progress beyond the description of a particular language by giving a formal specification of a general BDI architecture that can be used as the basis for providing further formal specifications of more sophisticated systems.
Anti-adenovirus activity, antioxidant potential, and phenolic content of black tea (Camellia sinensis Kuntze) extract

Abstract Background Adenovirus (ADV) causes a number of diseases in human, and to date, no specific antiviral therapy is approved against this virus. Thus, searching for effective anti-ADV agents seems to be an urgent requirement. Many studies have shown that components derived from medicinal plants have antiviral activity. Therefore, the present study was aimed to evaluate in vitro anti-ADV activity and also antioxidant potential and total phenolic compounds of black tea (Camellia sinensis) crude extract. Methods In this study, the hydroalchoholic extract of black tea was prepared and its anti-ADV activity was evaluated on HEp2 cell line using MTT [3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide] assay. The 50 % inhibitory concentration (IC50) and 50 % cytotoxicity concentration (CC50) of the extract were determined using regression analysis. Its inhibitory effect on adsorption and/or post-adsorption stages of the virus replication cycle was evaluated. To determine antioxidant activity, total phenol content, and flavonoids content of the extract, the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, Folin–Ciocalteu method, and aluminum chloride colorimetric method were used, respectively. Results The CC50 and the IC50 of the extract were 165.95±12.7 and 6.62±1.4 µg/mL, respectively, with the selectivity index (SI) of 25.06. This extract inhibited ADV replication in post-adsorption stage. The IC50 of DPPH radical was 8±1.41 μg/mL, compared with butylated hydroxytoluene, with IC50 of 25.41±1.89 μg/mL. The total phenol and flavonoid contents of the extract were 341.8±4.41 mg gallic acid equivalent per gram and 21.1±2.11 mg/g, respectively. Conclusions Having SI value of 25.06 with inhibitory effect on ADV replication, particularly during the post-adsorption period, black tea extract could be considered as a potential anti-ADV agent. The antiviral activity of this extract could be attributed to its phenolic compounds.
