Compensation of Complex Hysteresis and Creep Effects in Piezoelectrically Actuated Systems —A New Preisach Modeling Approach

Undesired complex hysteretic nonlinearities and complex log(t)-type creep dynamics with asymmetrical branching characteristics are present to varying degrees in virtually all smart-material based sensors and actuators provided that they are driven with sufficiently high amplitudes. In motion and active vibration control applications, for example, these nonlinearities can excite unwanted dynamics which leads in the best case to reduced closed-loop system performance and in the worst case to unstable closed-loop system operation. From the practical point of view it is extremely useful to cancel these types of nonlinearities by a feedforward compensation strategy. Therefore, the present article describes a new compensator for these types of actuator nonlinearities with large creep processes based on the so-called Preisach approach. It discusses a rigorous existence, uniqueness and stability proof for the compensator. Moreover, it deduces an algorithm for the calculation of the compensator in real-time applications and presents some experimental results which document the applicability of the method for practical applications.
How Important Is Sustainability Education to Hospitality Programs?

Although sustainability is at the forefront globally, awareness of its importance within the hospitality curriculum of universities in the United States has been limited. This study appraised importance of sustainability education in hospitality curriculums by assessing students, educators, and industry leaders in the United States. Results revealed significant differences between these stakeholders as to environmental attitudes, behaviors, interest in sustainability, and the significance of environmental concerns in a hospitality curriculum. Results also showed how the stakeholders' views were different with regard to the relevance of environmental topics in the hospitality curriculum and how best sustainability theory and practices can be taught.
Dental caries in children with asthma undergoing treatment with short-acting beta2-agonists.

AIM This study sought to evaluate possible higher risk for dental caries among asthmatic children undergoing treatment with short-acting beta2-agonists. METHODS Dental clinical assessments, saliva analysis and a questionnaire survey were carried out on 60 children aged 6-12, of whom 30 were asthmatic subjects undergoing treatment with short-acting beta2-agonists and 30 were used as controls. The obtained data for DMFT/dmft scores, Silness-Löe plaque index, buffer capacity and bacteria counts for Streptococcus mutans and Lactobacillus in the saliva, oral hygiene and dietary habits were compared using Student t-test and Pearson chi-square test. RESULTS We registered a higher DMFT score among asthmatics of 1.2-/+1.8 (SD) and 0.3-/+0.8 among non-asthmatic patients (p<0.05), while comparison of dmft scores between the examined groups showed not significant (Student t-test). Saliva analysis revealed lower buffer capacity in 43.3% of the asthmatic children, followed by higher cariogenic bacteria counts in their saliva (p<0.05 Student t-test). These results show the lower plaque index in the asthmatic group (1.6+/-0.4) compared with the control (2.1+/-0.3). Asthmatic children expressed better oral-health habits with more frequent tooth- brushing and usage of fluorides. CONCLUSION The results from our study suggest a higher caries-susceptibility among asthmatic children undergoing treatment with short-acting beta2-agonists, but a clear association between these drugs, salivary changes and dental caries among children, still remains to be demonstrated.
Screen-off traffic characterization and optimization in 3G/4G networks

Today's cellular systems operate under diverse resource constraints: limited frequency spectrum, network processing capability, and handset battery life. We consider a novel and important factor, handset screen status, i.e., whether the screen is on or off, which was ignored by previous approaches for optimizing cellular resource utilization. Based on analyzing real smartphone traffic collected from 20 users over five months, we find that off-screen traffic accounts for 58.5% of the total radio energy consumption although their traffic volume contribution is much smaller. Such unexpected results are attributed to the unique cellular resource management policy that is not well understood by developers, leading to cellular-unfriendly mobile apps. We then make a further step by proposing screen-aware optimization, by leveraging the key observation that screen-off traffic is much more delay-tolerant than its screen-on counterpart due to a lack of user interaction. Our proposal can better balance the key tradeoffs in cellular networks. It saves up to 60.92% of the network energy and reduces signaling and delay overhead by 25.33% and 30.59%, respectively.
How do you connect?: analysis of social capital accumulation in connectivist MOOCs

Connections established between learners via interactions are seen as fundamental for connectivist pedagogy. Connections can also be viewed as learning outcomes, i.e. learners' social capital accumulated through distributed learning environments. We applied linear mixed effects modeling to investigate whether the social capital accumulation interpreted through learners' centrality to course interaction networks, is influenced by the language learners use to express and communicate in two connectivist MOOCs. Interactions were distributed across the three social media, namely Twitter, blog and Facebook. Results showed that learners in a cMOOC connect easier with the individuals who use a more informal, narrative style, but still maintain a deeper cohesive structure to their communication.
The Isomap Algorithm and Topological Stability

Tenenbaum et al . ([1][1]) presented an algorithm, Isomap, for computing a quasi-isometric, low-dimensional embedding of a set of high-dimensional data points. Two issues need to be raised concerning this work. First, the basic approach presented by Tenenbaum et al . is not new, having been
Differential immunohistochemical detection of transforming growth factor α, amphiregulin and CRIPTO in human normal and malignant breast tissues

The expression of growth factors, such as transforming growth factor α (TGFα), amphiregulin (AR) and CRIPTO, a type‐1 tyrosine‐kinase growth factor receptor‐(erbB‐2), and a tumor‐suppressor gene (p53), that have been implicated in the development and/or the progression of breast cancer, was evaluated by immunohistochemistry in 100 human primary infiltrating breast carcinomas (IBC). AR and CRIPTO immunoreactivity was also assessed in 55 human breast ductal carcinomas in situ (DCIS). Within the 100 IBC, 80, 50, 73, 17, and 34 tumors expressed moderate to high levels of TGFα, AR, CRIPTO, erbB‐2, and p53 respectively. In addition, AR and CRIPTO immunoreactivity were found in 11 and in 26 out of 55 DCIS respectively. In contrast, only 4, 3, and 2 out of 10 normal mammary‐gland samples were weakly positive for TGFα, AR, and CRIPTO expression, respectively, whereas none was positive for erbB‐2 or p53. Within the 100 IBC, expression of erbB‐2 significantly correlated with high histologic and nuclear grading, with high growth fraction, and with estrogen‐receptor(ER)‐ and progesterone‐receptor(PgR)‐negative tumors. A statistically significant correlation was also observed between p53 expression and high histologic grading, high growth fraction, and PgR‐negative tumors. In contrast, no significant correlations were found between TGFα, AR, and CRIPTO immunoreactivity and various clinicopathological parameters, with the exception of a positive correlation between TGFα and ER expression. These data demonstrate that TGFα, AR, and CRIPTO expression are significantly increased in malignant mammary epithelium relative to normal epithelium. In particular, the differential expression of CRIPTO may serve as a potential tumor marker for breast carcinogenesis. © 1996 Wiley‐Liss, Inc.
The Effects of Behaviour Modelling Training on Managerial Attitudes and Performance: A Field Experiment

To examine the impact of behaviour modelling training on attitudes and performance, 25 branch managers in an insurance company were randomly assigned to either a training or non‐training condition. The trainees spent 48 hours on eight modelling modules, designed to improve their skills in dealing with their subordinates. The trainees reacted favourably to the training programme immediately and six months later. The trainees also received significantly higher performance ratings than managers in the non‐training condition a year later. Their branch profits also increased significantly more than did those of the non‐training managers over the same period. These results suggest that intensive behaviour modelling can improve attitudes and performance in certain kinds of jobs.
Limiting inbreeding in disjunct and isolated populations of a woody shrub

Abstract Pollen movements and mating patterns are key features that influence population genetic structure. When gene flow is low, small populations are prone to increased genetic drift and inbreeding, but naturally disjunct species may have features that reduce inbreeding and contribute to their persistence despite genetic isolation. Using microsatellite loci, we investigated outcrossing levels, family mating parameters, pollen dispersal, and spatial genetic structure in three populations of Hakea oldfieldii, a fire‐sensitive shrub with naturally disjunct, isolated populations prone to reduction in size and extinction following fires. We mapped and genotyped a sample of 102 plants from a large population, and all plants from two smaller populations (28 and 20 individuals), and genotyped 158–210 progeny from each population. We found high outcrossing despite the possibility of geitonogamous pollination, small amounts of biparental inbreeding, a limited number of successful pollen parents within populations, and significant correlated paternity. The number of pollen parents for each seed parent was moderate. There was low but significant spatial genetic structure up to 10 m around plants, but the majority of successful pollen came from outside this area including substantial proportions from distant plants within populations. Seed production varied among seven populations investigated but was not correlated with census population size. We suggest there may be a mechanism to prevent self‐pollination in H. oldfieldii and that high outcrossing and pollen dispersal within populations would promote genetic diversity among the relatively small amount of seed stored in the canopy. These features of the mating system would contribute to the persistence of genetically isolated populations prone to fluctuations in size.
SERTRALINE AND BUSPIRONE IN ADOLESCENT DELUSIONAL BODY DYSMORPHIC DISORDER

case of Rabbit syndrome which occurred twice in two different admissions while she received highpotency antipsychotics for just one week, the response to shift on low potency and adding antiparkinson medicines was as good as in her case (Jain, 1993) I will like to know from the author, if extrpyramidal side effects also developed on the same day the perioral movements were noted ? Extrapyramidal side effects are usually visible after one or two days of antipsychotic administration. It looks that perioral movements were noted after a week of initiation of treatment and then only antiparkinson agents were started which mean that EPS also occurred on seventh day.
A SURVEY ON THE IMPACT OF INFORMATION TECHNOLOGY ON THE CANADIAN ARCHITECTURE , ENGINEERING AND CONSTRUCTION INDUSTRY

A survey about the current and planned use of information technology (IT) and its impact on the architecture, engineering, and construction (AEC) industry in Canada has been conducted at the end of 1998 and beginning of 1999. It was found that many business processes are now almost completely computerised and the tendency is toward a greater computerisation of the remaining processes. Although the Internet has been adopted by most firms surveyed, design information is still exchanged in its traditional form. These firms have increased and will increase further their investment in IT, which has raised productivity in most business processes and has resulted in an increase in the quality of documents and in the speed of work, better financial controls and communications, and simpler access to common data. However, the benefits of IT come at a cost since the complexity of work, the administrative needs and the costs of doing business have all increased. The continual demand for upgrading and the greater know-how required are considered important obstacles. The two most important areas of future research is the implementation of computer-integrated design and construction as well as the development of new tools to support concurrent design and to assist designers in the conceptual stages.
Localization of the Organic Anion Transporting Polypeptide 2 (Oatp2) in Capillary Endothelium and Choroid Plexus Epithelium of Rat Brain

In this study we investigated the distribution of a recently cloned polyspecific organic anion transporting polypeptide (Oatp2) in rat brain by nonradioactive in situ hybridization histochemistry and immunofluorescence microscopy. The results demonstrate that Oatp 2 is expressed in brain capillary and in plexus epithelial cells. At the blood-brain barrier (BBB), Oatp 2 expression could be co-localized with the endothelial marker vWF (von Willebrand factor) but not with the astrocyte marker GFAP (glial fibrillary acidic protein). In choroid plexus epithelial cells, Oatp 2 could be localized to the basolateral cell pole, whereas the first member of the Oatp gene family of membrane transporters to be cloned (Oatp 1) co-localized with the α1subunit of Na,K-ATPase at the apical plasma membrane domain. Because Oatp 1 and Oatp 2 have been previously shown to mediate transmembrane transport of a wide variety of amphipathic organic compounds, including many drugs and other xenobiotics, the histochemical localization of Oatp 2 at the BBB and of Oatp 1 and Oatp 2 in the choroid plexus imply a role for these transporters in the active exchange of amphipathic solutes between the blood, brain, and cerebrospinal fluid compartments.
Safe Interdomain Routing Under Diverse Commercial Agreements

Commercial agreements drive the routing policies used in today's Internet. The two most extensively studied commercial agreements are transit and peering; however, they are only two of many diverse and continuously evolving commercial agreements that ISPs enter into. So far, the only known practical safe and robust routing policy is Gao and Rexford's policy guideline, which is applicable to transit and peering agreements only. It is, therefore, of importance to identify routing policies that are safe and robust and, at the same time, capable of accommodating the diverse commercial agreements existing in the Internet. In particular, this paper investigates the extent to which routing policies can be devised to accommodate complex mutual transit agreements. We propose a series of policy guidelines that allow mutual transit agreements with progressively broader semantics to be established. Those policy guidelines guarantee routing safety and robustness as long as the autonomous system (AS) graph satisfies a corresponding set of precise topological constraints. An experimental evaluation of the proposed policy guidelines demonstrates the benefits they would likely afford in terms of routing reliability if adopted in the current Internet.

of continued uncertainty about the causes of smog as well as Detroit’s hostility to reform. The final two chapters offer an intriguing interpretation of the gradual evolution of the German environmental movement compared to the more “revolutionary” upheavals in the United States. When viewed against the German backdrop, it appears that the very success of early cooperative schemes in the United States led to a degree of institutional inertia that, by eventually discrediting cooperation itself, helped to bring about the radical legislative changes of 1970. By contrast, in Germany the “strong state” that had initially hindered anti-smoke initiatives in the early 1900s eventually proved beneficial in encouraging meaningful cooperation from industry in the postwar period. These arguments carry a number of interesting implications, and to his credit Uekoetter pulls no punches in drawing wider conclusions from his findings. The modern environmental movement, he argues, was not a grand new awakening to a previously ignored problem but merely the most recent expression of concerns that have been around for well over a century. Indeed, significant strides were made in air quality throughout the entire period under study, including the 1950s and 1960s. What led to the “environmental revolution” in the United States was not a history of industrial intransigence per se (German industrialists were scarcely more enthralled by controls than their American counterparts) or relative public indifference, but rather the continuation of a dominant regulatory tradition that gave too much power to industry and thus failed to keep up with the times. Perhaps most notable is Uekoetter’s eloquent historical critique of the instinctive tendency among some environmentalists to view industry as an implacable foe rather than potential collaborator in the reduction of air pollution. Industrialists and engineers often acted as valued partners in smokeabatement efforts; the account he presents is therefore not one that pits ecological concerns firmly against economic interests. If there is a lesson to be learned from the “age of smoke,” it is, according to Uekoetter, the importance of compromise and cooperation in achieving real environmental improvements.
Stochasticity of Bias and Nonlocality of Galaxy Formation: Linear Scales

If one wants to represent the galaxy number density at some point in terms of only the mass density at the same point, stochasticity appears in such a relation, which is referred to as "stochastic bias. " The stochasticity is there because the galaxy number density is not merely a local function of a mass density field but is also a nonlocal functional. Thus, the phenomenological stochasticity of the bias should be accounted for by nonlocal features of galaxy formation processes. Based on mathematical arguments, we show that there are simple relations between biasing and nonlocality on linear scales of density fluctuations and that the stochasticity in Fourier space does not exist on linear scales under a certain condition, even if galaxy formation itself is a complex nonlinear and nonlocal process. The stochasticity in real space, however, arises from the scale dependence of the bias parameter, b. As examples, we derive the stochastic bias parameters of simple nonlocal models of galaxy formation, i.e., the local Lagrangian bias models, the cooperative model, and the peak model. We show that the stochasticity in real space is also weak, except on scales of nonlocality of galaxy formation. Therefore, we do not have to worry too much about the stochasticity on linear scales, especially in Fourier space, even if we do not know the details of the galaxy formation process.
Optimal Energy Harvesting From Serially Connected Microbial Fuel Cells

Microbial fuel cell (MFC) converts electrochemical energy from organic matter into electricity by means of chemotrophic bacteria metabolisms. The MFC power output is limited in voltage and in current in the range of microwatts or milliwatts per liter. The output power may be improved by association of MFCs either in series or in parallel. The serial association of a large number of MFCs presents a benefit in effective output voltage but may suffer from several limitations. The most important is that the possible dispersion between the microgenerators leads to a nonoptimal stack efficiency. A power management unit is also necessary to harvest energy from a single MFC or a group of connected MFCs. The converter functions are to step up the voltage and to control the operating point of the MFC(s). The aim of this paper is to build an appropriate architecture for energy harvesting from series-connected MFCs, which feature disparate behaviors. A system to meet low-power sensor consumption specifications is composed of a stack of nonuniform serially connected MFCs, a voltage balancing circuit, and a maximum power point converter. The system is designed, fabricated, and tested. A percent of maximum power achieved of 86% is demonstrated for 1.5 mW of harvested power from four MFCs with large dispersion in characteristics.

Media Representations of Intimate Partner Violence and Punishment Preferences: Exploring the Role of Attributions and Emotions

This study examines Weiner's attribution–emotion–action model using news stories derived from existent media messages about intimate partner violence containing information designed to increase or decrease attributions of responsibility both toward the perpetrator and toward the victim. Participants (N=251) were randomly assigned to one of four conditions, exposed to a stimulus message, then completed a survey. The attribution–emotion–action model was largely supported. Although multiple emotions were experienced, only certain emotions were significant in determining punishment preference, and these emotions varied by target (i.e., perpetrator or victim). How news stories may be influencing public opinion and support for public health and criminal justice policies is discussed.
Sharing automatically tracked activity data: implications for therapists and people with mobility impairments

The ability to share automatically tracked health and fitness behaviors has yielded benefits ranging from increasing user motivation to providing therapists with greater insight into their patients' progress. While past work on sharing this data has primarily focused on users with typical motor abilities, features are now emerging in mainstream tracking technologies to extend to people with mobility impairments (e.g., tracking wheelchair rolling). This paper explores opportunities specifically for users with mobility impairments to share this automatically tracked data both with peers and with physical, occupational or recreational therapists. We conducted semi-structured interviews with 10 therapists and 10 people with mobility impairments. The interviews focused on current and desired activity-tracking and sharing practices, and included a design probe activity to more concretely assess the perceived utility of sharing tracked fitness data. We report on attitudes and concerns toward sharing fitness data from the perspective of therapists and people with mobility impairments as well as outline design opportunities to explore in future work.
