A Planar Magnetically Coupled Resonant Wireless Power Transfer System Using Printed Spiral Coils

A fully planar wireless power transfer (WPT) system via strongly coupled magnetic resonances is presented. In it, both the transmitter and the receiver are planarized with the use of coplanar printed spiral coils (PSCs) and a printed loop. An equivalent circuit model of the proposed planar WPT system is derived to facilitate the design, and a flowchart is provided for the optimization of the system with given size constraints. To realize high peak power transfer efficiency, the quality factor of individual loop or resonator, the mutual coupling between resonators, and the frequency splitting phenomenon of the system are analyzed in addition to the effect of the input impedance of the system on the transmission efficiency. Furthermore, parallel current paths are created by applying auxiliary strips to the backside of the substrates and connecting to the prime resonators using vias to decrease the resistance and to increase the quality factor of the PSC resonators, and this in turn further improves the transfer efficiency of the proposed planar WPT system. The measured results show that the proposed WPT system is able to provide a stable wireless power transfer with up to 81.68% efficiency at a distance of 10 cm. The planar structure and the high transfer efficiency make the proposed design a suitable candidate for wireless power transfer of small portable electronic devices.
On the impact of MOOCs on engineering education

From the early 90s, online education has been continually reshaping the notion of open learning. Massive Open Online Courses (MOOCs) have generated a paradigm shift in online education by presenting free high-quality education to anyone, anywhere with Internet access. Since 2012, MOOCs got attention of the universities, media and entrepreneurs. These online courses may change the world by 2022. This paper discusses major elements of MOOCs that can influence teaching and learning in engineering. It also explores the promise of online education in improving standard in-class engineering education.
Collective Intelligence and Human Culture

Examples of selfless behavior abound in nature. Cells within an organization sacrifice themselves to prevent spread of infections, worker bees in hives sacrifice their right to reproduce, many female mammals will suckle one another's offspring. Human cooperation and collaboration cover vast areas of activity and behavior, often placing their own reproductive success on the line for the benefit of another individual. Since the publication of Darwin's Origin of Species, biologists have struggled to reconcile evolution's "selfishness" with the clear evidence of cooperation in nature. The dominant view of evolution followed Tennyson's description of nature as "red in tooth and claw." Charles Darwin proposed evolution by natural selection in which individuals with desirable traits reproduce more than their peers and contribute more to the next generation. He called this competition the "struggle for life most severe." Evolution was commonly called "survival of the fittest." It appeared logical that one should not help a rival and should even cheat to win. Winning the game would be all that counts. Any observation of the many species of animals reveals a social nature. Indeed, it is unusual to see many animals apart from their group unless they are lost, injured, or ill. We have many English words to describe the grouping of animals; a covey of quail, a pod of whales, a herd of sheep, a pride of lions, a pack of wolves, an
Impact of Communicating Familial Risk of Diabetes on Illness Perceptions and Self-Reported Behavioral Outcomes

OBJECTIVE
To assess the potential effectiveness of communicating familial risk of diabetes on illness perceptions and self-reported behavioral outcomes.


RESEARCH DESIGN AND METHODS
Individuals with a family history of diabetes were randomized to receive risk information based on familial and general risk factors (n = 59) or general risk factors alone (n = 59). Outcomes were assessed using questionnaires at baseline, 1 week, and 3 months.


RESULTS
Compared with individuals receiving general risk information, those receiving familial risk information perceived heredity to be a more important cause of diabetes (P < 0.01) at 1-week follow-up, perceived greater control over preventing diabetes (P < 0.05), and reported having eaten more healthily (P = 0.01) after 3 months. Behavioral intentions did not differ between the groups.


CONCLUSIONS
Communicating familial risk increased personal control and, thus, did not result in fatalism. Although the intervention did not influence intentions to change behavior, there was some evidence to suggest it increases healthy behavior.
Non-negative Tensor Factorization with missing data for the modeling of gene expressions in the Human Brain

Non-negative Tensor Factorization (NTF) has become a prominent tool for analyzing high dimensional multi-way structured data. In this paper we set out to analyze gene expression across brain regions in multiple subjects based on data from the Allen Human Brain Atlas [1] with more than 40 % data missing in our problem. Our analysis is based on the non-negativity constrained Canonical Polyadic (CP) decomposition where we handle the missing data using marginalization considering three prominent alternating least squares procedures; multiplicative updates, column-wise, and row-wise updating of the component matrices. We examine three gene expression prediction scenarios based on data missing at random, whole genes missing and whole areas missing within a subject. We find that the column-wise updating approach also known as HALS performs the most efficient when fitting the model. We further observe that the non-negativity constrained CP model is able to predict gene expressions better than predicting by the subject average when data is missing at random. When whole genes and whole areas are missing it is in general better to predict by subject averages. However, we find that when whole genes are missing from all subjects the model based predictions are useful. When analyzing the structure of the components derived for one of the best predicting model orders the components identified in general constitute localized regions of the brain. Non-negative tensor factorization based on marginalization thus forms a promising framework for imputing missing values and characterizing gene expression in the human brain. However, care also has to be taken in particular when predicting the genetic expression levels at a whole region of the brain missing as our analysis indicates that this requires a substantial amount of subjects with data for this region in order for the model predictions to be reliable.
Psoriasis: is it the tip of the iceberg for the quality of life of patients and their families?

OBJECTIVE
To evaluate the impact of psoriasis on patients' and their relatives' quality of life (QoL).


METHODS
Eighty patients with their accompanying family members were included in the study. For measuring health related QoL (HRQoL) of patients with psoriasis, two questionnaires were used: Short Form 36 Health Survey (SF-36) and EuroQol (EQ-5D). Disease-specific HRQoL was assessed by the Dermatology Life Quality Index. For measuring the quality of life of patients' relatives, a specific questionnaire for dermatological diseases was used (Family Dermatology Life Quality Index, FDLQI).


RESULTS
Of our patients, 88.3% reported that their disease affects in many and different ways their QoL whereas only 11.2% reported that psoriasis does not influence at all their life. Regarding FDLQI, 90% of the participating family members, responded that their relative's psoriasis affected their own QoL.


CONCLUSIONS
Psoriasis is a chronic disease that affects in a cumulative way the quality of life of both patients and their close relatives.

Fast Kernels for String and Tree Matching

In this paper we present a new algorithm suitable for matching discrete objects such as strings and trees in linear time, thus obviating dynamic programming with quadratic time complexity. Furthermore, prediction cost in many cases can be reduced to linear cost in the length of the sequence to be classified, regardless of the number of support vectors. This improvement on the currently available algorithms makes string kernels a viable alternative for the practitioner.
Comprehensive analysis of the MYB-NFIB gene fusion in salivary adenoid cystic carcinoma: Incidence, variability, and clinicopathologic significance.

PURPOSE
The objectives of this study were to determine the incidence of the MYB-NFIB fusion in salivary adenoid cystic carcinoma (ACC), to establish the clinicopathologic significance of the fusion, and to analyze the expression of MYB in ACCs in the context of the MYB-NFIB fusion.


EXPERIMENTAL DESIGN
We did an extensive analysis involving 123 cancers of the salivary gland, including primary and metastatic ACCs, and non-ACC salivary carcinomas. MYB-NFIB fusions were identified by reverse transcriptase-PCR (RT-PCR) and sequencing of the RT-PCR products, and confirmed by fluorescence in situ hybridization. MYB RNA expression was determined by quantitative RT-PCR and protein expression was analyzed by immunohistochemistry.


RESULTS
The MYB-NFIB fusion was detected in 28% primary and 35% metastatic ACCs, but not in any of the non-ACC salivary carcinomas analyzed. Different exons in both the MYB and NFIB genes were involved in the fusions, resulting in expression of multiple chimeric variants. Notably, MYB was overexpressed in the vast majority of the ACCs, although MYB expression was significantly higher in tumors carrying the MYB-NFIB fusion. The presence of the MYB-NFIB fusion was significantly associated (P = 0.03) with patients older than 50 years of age. No correlation with other clinicopathologic markers, factors, and survival was found.


CONCLUSIONS
We conclude that the MYB-NFIB fusion characterizes a subset of ACCs and contributes to MYB overexpression. Additional mechanisms may be involved in MYB overexpression in ACCs lacking the MYB-NFIB fusion. These findings suggest that MYB may be a specific novel target for tumor intervention in patients with ACC.
Challenges to the Hypothesis of Extended

* In recent decades, an intriguing view of human cognition has garnered increasing support. According to this view, which I will call 'the hypothesis of extended cognition' ('HEC', hereafter), human cognitive processing literally extends into the environment surrounding the organism, and human cognitive states literally comprise—as wholes do their proper parts— elements in that environment; in consequence, while the skin and scalp may encase the human organism, they do not delimit the thinking subject. 1 The hypothesis of extended cognition should provoke our critical interest. Acceptance of HEC would alter our approach to research and theorizing in cognitive science and, it would seem, significantly change our conception of persons. Thus, if HEC faces substantive difficulties, these should be brought to light; this paper is meant to do just that, exposing some of the problems HEC must overcome if it is to stand among leading views of the nature of human cognition. The essay unfolds as follows: The first section consists of preliminary remarks, mostly about the scope and content of HEC as I will construe it. Sections II and III clarify HEC by situating it with respect to related theses one finds in the literature—the hypothesis of embedded cognition Association. I would like to express my appreciation to members of all three audiences for their useful feedback (especially William Lycan at the Mountain-Plains and David Chalmers at the APA), as well as to my conference commentators, Robert Welshon and Tadeusz Zawidzki. I also benefited from discussing extended cognition with 2 and content-externalism. The remaining sections develop a series of objections to HEC and the arguments that have been offered in its support. The first objection appeals to common sense: HEC implies highly counterintuitive attributions of belief. Of course, HEC-theorists can take, and have taken, a naturalistic stand. They claim that HEC need not be responsive to commonsense objections, for HEC is being offered as a theoretical postulate of cognitive science; whether we should accept HEC depends, they say, on the value of the empirical work premised upon it. Thus, I consider a series of arguments meant to show that HEC is a promising causal-explanatory hypothesis, concluding that these arguments fail and that, ultimately, HEC appears to be of marginal interest as part of a philosophical foundation for cognitive science. If the cases canvassed here are any indication, adopting HEC results in a significant loss of explanatory power or, at the …
Structure and Evolution of the Bering Sea Shelf: Abstract

Abstract The Bering shelf is underlain by two Cenozoic structural provinces, an inner and generally coastal one of essentially undeformed Cenozoic basins that occupy the large reentrants of this sea, and an outer continental-margin province with parallel basement ridges and basins overlain by as much as ten kilometers of Cenozoic sediment. The inner provinces includes three major structural sags of Mesozoic and older basement rock: Bristol, Anadyr and Norton basins, containing three kilometers or more of neritic Cenozoic strata. A fourth basin, St. Matthew, trends NE-SW between St. Lawrence and St. Matthew Islands. It may be associated with the offshore extension of the Kaltag fault. The sedimentary fill in the basin (as much as 1.3 km) is not appreciably disturbed, suggesting that the Kaltag fault has not been active since the Early Tertiary. The outer structural province comprises ten elongate basins. These are grabens or half-grabens and they contain up to ten kilometers of Mesozoic(?) and Cenozoic sediment. The basins are bounded by active normal (growth) faults, suggesting that the outer shelf area may be collapsing and rifting away from the inner shelf. We speculate that the outer structural province is a fragmented and submerged Mesozoic fold belt that formed above oceanic crust along an oblique convergence zone extending northwestward from Alaska to Siberia. A belt of highly magnetic volcanic and plutonic rocks that passes through St. Matthew Island is the magmatic are associated with the Mesozoic subduction zone. The inner province basins, like those of the outer province, appear to be superimposed above inherited late Mesozoic trends, but they are in part or wholly underlain by Mesozoic and older continental crust.
Perceptions of users and providers on barriers to utilizing skilled birth care in mid- and far-western Nepal: a qualitative study

Background Although skilled birth care contributes significantly to the prevention of maternal and newborn morbidity and mortality, utilization of such care is poor in mid- and far-western Nepal. This study explored the perceptions of service users and providers regarding barriers to skilled birth care. Design We conducted 24 focus group discussions, 12 each with service users and service providers from different health institutions in mid- and far-western Nepal. All discussions examined the perceptions and experiences of service users and providers regarding barriers to skilled birth care and explored possible solutions to overcoming such barriers. Results Our results determined that major barriers to skilled birth care include inadequate knowledge of the importance of services offered by skilled birth attendants (SBAs), distance to health facilities, unavailability of transport services, and poor availability of SBAs. Other barriers included poor infrastructure, meager services, inadequate information about services/facilities, cultural practices and beliefs, and low prioritization of birth care. Moreover, the tradition of isolating women during and after childbirth decreased the likelihood that women would utilize delivery care services at health facilities. Conclusions Service users and providers perceived inadequate availability and accessibility of skilled birth care in remote areas of Nepal, and overall utilization of these services was poor. Therefore, training and recruiting locally available health workers, helping community groups establish transport mechanisms, upgrading physical facilities and services at health institutions, and increasing community awareness of the importance of skilled birth care will help bridge these gaps.

Ocean Related Senior Design Projects For Mechanical Engineers At Umass Dartmouth

This paper discusses several ocean-related capstone design projects completed by mechanical engineering students at the University of Massachusetts Dartmouth. Some projects are detailed analytical projects that involved complex simulations, others are systems engineering projects that involved manufacturing and prototype testing. Different aspects of the design process are emphasized by the different styles of project, and all met with success. Several projects were performed in collaboration with other Departments at UMD or with local institutions that work in the oceanographic field. Neither students nor faculty advisors were assigned specific projects, yet nearly one third of the capstone design projects completed in the last three years have had an ocean or marine emphasis. Introduction Mechanical Engineering students at the University of Massachusetts Dartmouth (UMD) are required to take a capstone design course in their senior year. Until fall 2002, this 4-credit course was offered during the spring semester only. Beginning in the fall of 2002, the course was changed to a 2-semester sequence, offering 2 credits for each semester. In the fall semester, students are expected to form design teams, select a design project, secure a faculty advisor for that project, write a project proposal that includes both a schedule and a budget, and begin design work. Another major component of the fall course is practical engineering ethics. During the spring semester, the students are expected to complete their design projects, write a comprehensive final report, and publicly present their design projects before the faculty, a panel of judges from industry, and their fellow students. Students meet weekly with both their project advisor and the course facilitator, and write weekly memos updating their progress. Although there is no formal program at UMD for ocean or marine-related engineering, several senior design projects of late have had a marine emphasis. On occasion, these projects have a connection with other departments or facilities of the University of Massachusetts or local research institutions. For example, one project was conducted through the Center for Marine Science and Technology (CMAST), a UMassaffiliated research laboratory that has recently started a Ph.D. program. One project was done in conjunction with the Woods Hole Oceanographic Institution, one of the US premier ocean research facilities; and another project was completed jointly with students
Activating visual energy: The MA circle and the art of Sándor Bortnyik

Abstract The article examines how energetically and biomechanically-based aesthetics, reception theories, and political ideas could inform, or inspire, leftist visual and poetic representation and choice of style in Hungarian modernism during the 1918–19 political upheavals, as a response to modern technology's effects. In connection to these views, the article also reconsiders the political ambiguities of Bortnyik's art in relation to Hungarian anarchism.
Optical Flow-based 3D Human Motion Estimation from Monocular Video

This paper presents a method to estimate 3D human pose and body shape from monocular videos. While recent approaches infer the 3D pose from silhouettes and landmarks, we exploit properties of optical flow to temporally constrain the reconstructed motion. We estimate human motion by minimizing the difference between computed flow fields and the output of our novel flow renderer. By just using a single semi-automatic initialization step, we are able to reconstruct monocular sequences without joint annotation. Our test scenarios demonstrate that optical flow effectively regularizes the under-constrained problem of human shape and motion estimation from monocular video. Fig. 1: Following our main idea we compute the optical flow between two consecutive frames and match it to an optical flow field estimated by our proposed optical flow renderer. From left to right: input frame, color-coded observed flow, estimated flow, resulting pose.
Project risk evaluation using a fuzzy analytic hierarchy process: An application to information technology projects

Projects are critical to the realization of performing organization’s strategies. Each project contains some degree of risk and it is required to be aware of these risks and to develop the necessary responses to get the desired level of project success. Because projects’ risks are multidimensional, they must be evaluated by using multi-attribute decision-making methods. The aim of this article is to provide an analytic tool to evaluate the project risks under incomplete and vague information. The fuzzy analytic hierarchy process ~AHP! as a suitable and practical way of evaluating project risks based on the heuristic knowledge of experts is used to evaluate the riskiness of an information technology ~IT! project of a Turkish firm. The means of the triangular fuzzy numbers produced by the IT experts for each comparison are successfully used in the pairwise comparison matrices. © 2006 Wiley Periodicals, Inc.
Attention training and the threat bias: An ERP study

Anxiety is characterized by exaggerated attention to threat. Several studies suggest that this threat bias plays a causal role in the development and maintenance of anxiety disorders. Furthermore, although the threat bias can be reduced in anxious individuals and induced in non-anxious individual, the attentional mechanisms underlying these changes remain unclear. To address this issue, 49 non-anxious adults were randomly assigned to either attentional training toward or training away from threat using a modified version of the dot probe task. Behavioral measures of attentional biases were also generated pre- and post-training using the dot probe task. Event-related potentials (ERPs) were generated to threat and non-threat face pairs and probes during pre- and post-training assessments. Effects of training on behavioral measures of the threat bias were significant, but only for those participants showing pre-training biases. Attention training also influenced early spatial attention, as measured by post-training P1 amplitudes to cues. Results illustrate the importance of taking pre-training attention biases in non-anxious individuals into account when evaluating the effects of attention training and tracking physiological changes in attention following training.
