Deployable and Conformal Planar Micro-Devices: Design and Model Validation

We report a design concept for a deployable planar microdevice and the modeling and experimental validation of its mechanical behavior. The device consists of foldable membranes that are suspended between flexible stems and actuated by push-pull wires. Such a deployable device can be introduced into a region of interest in its compact “collapsed” state and then deployed to conformally cover a large two-dimensional surface area for minimally invasive biomedical operations and other engineering applications. We develop and experimentally validate theoretical models based on the energy minimization approach to examine the conformality and figures of merit of the device. The experimental results obtained using model contact surfaces agree well with the prediction and quantitatively highlight the importance of the membrane bending modulus in controlling surface conformality. The present study establishes an early foundation for the mechanical design of this and related deployable planar microdevice concepts.
Aberrant visual projections in the Siamese cat

1. Guillery has recently shown that the Siamese cat has a grossly abnormal lateral geniculate body. His anatomical study suggested that certain fibres originating in the temporal retina of each eye cross in the chiasm instead of remaining uncrossed. They thus reach the wrong hemispheres, but in the geniculate they terminate in the regions that the missing fibres from the ipsilateral eye would normally have occupied. The result is that each hemisphere receives an input from parts of the ipsilateral field of vision, this input being entirely from the opposite eye. The purpose of the present work was to study the physiological consequences of this aberrant projection, in the lateral geniculate body and visual cortex.
A proposed model of expatriates in multinational corporations

Purpose – The purpose of this paper is to examine the relationship between job satisfaction, family support, learning orientation, organizational socialization and cross‐cultural training and cross‐cultural adjustment in the proposed model.Design/methodology/approach – A quantitative research method was used, and correction and regression were employed. The study undertook a multidimensional approach in its assessment of the adjustment of Taiwanese financial institution expatriates.Findings – This study found that job satisfaction played an important role in the proposed model of expatriate adjustment in an international assignment. Also found to be of importance was the role of organization socialization.Research limitations/implications – The conclusions of this study pertain only to Taiwanese financial institution expatriates in the USA, and cannot be generalized for cross‐cultural adjustment in other countries.Practical implications – Given the associations between job satisfaction and cross‐cultural .
Assembly and motility of eukaryotic cilia and flagella. Lessons from Chlamydomonas reinhardtii.

Cilia and flagella are among the most ancient cellular organelles, providing motility for primitive eukaryotic cells living in an aqueous environment. During adaptation to life on land, some groups of organisms, including advanced fungi, red algae, cellular slime molds, conifers, and angiosperms,
Copepod reproduction is unaffected by diatom aldehydes or lipid composition

We investigated whether reduced reproductive success of copepods fed with diatoms was related to nutritional imbalances with regard to essential lipids or to the production of inhibitory aldehydes. In 10‐d laboratory experiments, feeding, egg production, egg hatching success, and fecal pellet production of Temora longicornis were measured for six different diatom species as well as for a nondiatom control diet (Rhodomonas sp.). The experiments were accompanied by determinations of fatty acids, sterols, and polyunsaturated aldehydes (PUA) in the food. Although diatoms were generally ingested at high rates, they yielded a variable egg production response in copepods, ranging from high egg production in four species (two strains of Thalassiosira rotula, Chaetoceros affinis, and Thalassiosira weissflogii) to low egg production in two species (Leptocylindricus danicus and Skeletonema costatum). Egg hatching rates decreased after 4 d in all diatom treatments, irrespective of the egg production rate and without any relationship to diatom aldehyde production. Similarly, no evidence was found that diatoms are per se nutritionally inferior to nondiatom food. The lack of a distinct mechanism for the observed inhibitory activity of diatoms suggests that the cause(s) might be more complex. We suggest, as one possible explanation, that hatching‐specific nutritional deficiencies might be induced by incomplete digestion following from the low gut passage time of diatoms, as indicated by a strong correlation between egg viability and fecal pellet production.
FACTORS THAT BIAS EMPLOYEE PERFORMANCE APPRAISALS

The fair evaluation of employees is crucial to the well being of the organisation, the manager and the employee. This article looks at four factors that have been shown to bias the appraisal process. These factors are the style of dress of the employee vis‐a‐vis the rater, the attributions made by both rater and ratee regarding performance, the prior expectations of the supervisor regarding the employee's performance, and the effect of employee grievances on his or her subsequent evaluations. These four factors are but four of many possible biases that enter into the evaluation process because of the human dynamic. They are instructive, but more importantly they should serve to alert appraisers to the many possible biases that may be operative in them but of which they are unaware.
Is bigger better? Dyadic and multiparty integrative negotiations

Purpose – The purpose of the study is to empirically investigate the similarities and differences between dyads and four‐party groups in an integrative negotiation.Design/methodology/approach – Data are collected in a between subjects experiment. A total of 182 participants completed a negotiation role play and questionnaire. Hypotheses are tested using t‐tests, MANOVAs and two multiple regression analyses.Findings – Results demonstrate that dyads do outperform groups on both the economic and subjective measures of outcomes. Sharing of priority information and the fixed pie bias was higher in groups than in dyads. For dyads the procedure used (considering more than one issue at a time) led to higher economic outcomes, and both procedure and problem solving were important for subjective outcomes. For four‐party negotiations, problem solving was significantly related to higher outcomes, on both economic and subjective outcomes, and procedure was moderately related to economic outcomes. Problem solving was s.
New Worst-Case Upper Bound for X3SAT

An algorithm running in O(1.1995n) is presented for counting models for exact satisfiability formulae(#XSAT). This is faster than the previously best algorithm which runs in O(1.2190n). In order to improve the efficiency of the algorithm, a new principle, i.e. the common literals principle, is addressed to simplify formulae. This allows us to eliminate more common literals. In addition, we firstly inject the resolution principles into solving #XSAT problem, and therefore this further improves the efficiency of the algorithm.
Effective Treatment of Refractory Pulmonary Hemorrhage with Monoclonal Anti-CD20 Antibody (Rituximab)

We report a 19-year-old female with systemic lupus erythematosus and lupus nephritis who developed pulmonary hemorrhage (PH) refractory to conventional immunosuppressive treatment. She was initially treated with intravenous methylprednisolone and cyclophosphamide pulses. She required mechanical ventilation due to a lack of responsiveness and her disease was considered refractory to conventional treatment. Rituximab was administered and this was followed by clinical improvement in both PH and nephritis. Rituximab may be a useful therapeutic option for the treatment of refractory PH.
The RP-Mdm2-p53 Pathway and Tumorigenesis

The dynamic processes of cell growth and division are under constant surveillance. As one of the primary “gatekeepers” of the cell, the p53 tumor suppressor plays a major role in sensing and responding to a variety of stressors to maintain cellular homeostasis. Recent studies have shown that inhibition of ribosomal biogenesis can activate p53 through ribosomal protein (RP)-mediated suppression of Mdm2 E3 ligase activity. Mutations in Mdm2 that disrupt RP binding have been detected in human cancers; however, the physiological significance of the RP-Mdm2 interaction is not completely understood. We generated mice carrying a single cysteine-to-phenylalanine substitution in the central zinc finger of Mdm2 (Mdm2C305F) that disrupts Mdm2’s binding to RPL11 and RPL5. Despite being developmentally normal and maintaining an intact p53 response to DNA damage, the Mdm2C305F mice demonstrate a diminished p53 response to perturbations in ribosomal biogenesis, providing the first in vivo evidence for an RP-Mdm2-p53 signaling pathway. Here we review some recent studies about RP-Mdm2-p53 signaling and speculate on the relevance of this pathway to human cancer.
TanDEM-X commissioning phase status

After the recent launch of the TanDEM-X satellite, the twin of TerraSAR-X, its demanding commissioning phase has started. On the one hand, it has to ensure the same monostatic operation performance as TerraSAR-X. On the other hand, the bistatic aspects have to be verified, which are essential for the acquisition of the global digital elevation model (DEM). This has to be done in a limited time period in order to keep the required nominal operation duration. This paper shows the summary of the commissioning phase activities and its running status.
A Digital Preservation Appliance Based on OpenBSD

The LOCKSS program has developed and deployed in a world-wide test a system for preserving access to academic journals published on the Web. The fundamental problem for any digital preservation system is that it must be affordable for the long term. To reduce the cost of ownership, the LOCKSS system uses generic PC hardware, open source software, and peer-to-peer technology. It is packaged as a ``network appliance'', a single-function box that can be connected to the Internet, configured and left alone to do its job with minimal monitoring or administration. The first version of this system was based on a Linux boot floppy. After three years of testing it was replaced by a second version, based on OpenBSD and booting from CD-ROM. We focus in this paper on the design, implementation and deployment of a network appliance based on an open source operating system. We provide an overview of the LOCKSS application and describe the experience of deploying and supporting its first version. We list the requirements we took from this to drive the design of the second version, describe how we satisfied them in the OpenBSD environment, and report on the initial
Changing Models of Transsexualism

SUMMARY The second half of the twentieth century saw the development within the psychological and medical communities of a transsexual model and procedures for identifying, describing, and treating individuals who sought sex reassignment. This model viewed transsexualism as a form of mental illness characterized by a pervasive and ongoing wish to be a member of the other sex. The model prescribes a set of medical and social procedures called sex reassignment, whereby an individual “changed sex. ” The 1990s saw the rise of a new model which explained transsexualism as a natural form of human variability. This model, which continues to gain prominence, views sex reassignment as but one of a variety of acceptable life choices for transsexual individuals, and recognizes the need and right of nontranssexual transgendered people to make similar choices. This paper discusses both models and touches on the social and treatment implications of the rise of the transgender model.
Thermal Influence on Multibias Small- and Large-Signal Parameters of GaAs pHEMT Fabricated in Multilayer 3-D MMIC

Temperature influence on the device behavior has been carried out on AlGaAs/InGaAs/GaAs-based pseudomorphic high-electron mobility transistor fabricated in multilayer 3-D monolithic microwave integrated circuits technology over multibias operation condition. The multibias thermal effect on the dc and RF, small-signal (up to 40 GHz) and large-signal parameters, including the third-order intercept points as well as the linear and third-order intermodulation output power performance at 4 GHz were analyzed and reported for the first time. In addition, the noise figure parameters of device have been reported and estimated at 10 GHz. The temperature coefficients of the device dc and RF parameters are carefully established at the peak transconductance condition. The results are important for the design optimizations of advanced monolithic multilayer integrations.
Age Differences in Perception of Workload for a Computer Task

Research concerned with age and work activities is an important area of investigation since the workforce is aging and there are concerns regarding economic dependency as well as labor shortages for certain occupations. Previous work by the research team indicated age differences in the performance and perceptions of task difficulty and fatigue for three simulated real-world computer tasks. This study is an extension of that research and is investigating the extent to which age differences in performance and perceptions of workload are moderated by experience and task practice. One hundred and twenty subjects aged 25 yrs. to 75 yrs. performed a real-world data entry task. Data will be presented regarding age differences in the perception of workload, stress, discomfort, and attitudes towards computers. The implications of these results for design interventions will be discussed.
Gambling as emotion management: developing a grounded theory of problem gambling

The numbers of individuals developing problems with gambling is on the increase. This study explored the nature of problem gambling through an analysis of the reported experiences of problem gamblers. A grounded theory approach involving the analysis of material from 14 male treatment seeking gamblers resulted in the identification of three main categories. These were emotion, control and costs of gambling. Central to the experience of all participants was the emotional nature of gambling, gambling being used either to induce or suppress arousal with a marked lack of other coping strategies. Control of gambling was an issue only in the context of efforts at behaviour change. Gambling costs were extensive including financial, relationship and emotional costs. Repeated failure of efforts at control resulted in tolerance of high levels of costs and repeated cycles of gambling. Patterns of interactions between these factors are identified in the emergent theory.
Inhibitory effects of basic fibroblast growth factor on chondrocyte differentiation

The role of basic fibroblast growth factor (bFGF) and insulin‐like growth factor I (IGF‐I) in cartilage growth was studied in primary cultures of rat rib growth plate chondrocytes. Growth factors effects on expression of the proto‐oncogene c‐fos, DNA synthesis, differentiation, and morphological changes were analyzed by in situ hybridization, 3H‐thymidine incorporation, and light and fluorescence microscopy. In serum‐deprived cells, bFGF induced a transient expression of c‐fos with a maximal effect 15–30 minutes after stimulation. After 24 h of culture it had a slightly lower stimulatory effect on DNA synthesis than IGF‐I, but became a significantly more potent mitogen than IGF‐I after 48 and 72 h. The stimulatory effect of bFGF on DNA synthesis coincided with a decrease in collagen type II and IGF‐II expression. In contrast, IGF‐I alone stimulated expression of these genes. In bFGF‐treated cultures, cell morphology and the appearance of actin filaments was changed. Polygonal chondrocytes became elongated, fibroblast‐like, and the smooth actin filaments were brush‐like and disrupted. Addition of IGF‐I reduced these changes without affecting c‐fos expression induced by bFGF. Our results suggest that bFGF stimulates cell proliferation by preventing terminal differentiation of chondrocytes. This effect is mediated by induction of c‐fos expression and a decrease in the steady‐state levels of transcripts for collagen II and IGF‐II.
Pagoda: Fine-Grained GPU Resource Virtualization for Narrow Tasks

Massively multithreaded GPUs achieve high throughput by running thousands of threads in parallel. To fully utilize the hardware, workloads spawn work to the GPU in bulk by launching large tasks, where each task is a kernel that contains thousands of threads that occupy the entire GPU. GPUs face severe underutilization and their performance benefits vanish if the tasks are narrow, i.e., they contain < 500 threads. Latency-sensitive applications in network, signal, and image processing that generate a large number of tasks with relatively small inputs are examples of such limited parallelism. This paper presents Pagoda, a runtime system that virtualizes GPU resources, using an OS-like daemon kernel called MasterKernel. Tasks are spawned from the CPU onto Pagoda as they become available, and are scheduled by the MasterKernel at the warp granularity. Experimental results demonstrate that Pagoda achieves a geometric mean speedup of 5.70x over PThreads running on a 20-core CPU, 1.51x over CUDA-HyperQ, and 1.69x over GeMTC, the state-of- the-art runtime GPU task scheduling system.
User performance versus precision measures for simple search tasks

Several recent studies have demonstrated that the type of improvements in information retrieval system effectiveness reported in forums such as SIGIR and TREC do not translate into a benefit for users. Two of the studies used an instance recall task, and a third used a question answering task, so perhaps it is unsurprising that the precision based measures of IR system effectiveness on one-shot query evaluation do not correlate with user performance on these tasks. In this study, we evaluate two different information retrieval tasks on TREC Web-track data: a precision-based user task, measured by the length of time that users need to find a single document that is relevant to a TREC topic; and, a simple recall-based task, represented by the total number of relevant documents that users can identify within five minutes. Users employ search engines with controlled mean average precision (MAP) of between 55% and 95%. Our results show that there is no significant relationship between system effectiveness measured by MAP and the precision-based task. A significant, but weak relationship is present for the precision at one document returned metric. A weak relationship is present between MAP and the simple recall-based task.
College Predisposition at High-Minority Enrollment, Low-Income Schools

This study incorporated variables suggested by qualitative studies of low-income and minority group students' precollege and college experiences to ascertain how community involvement and mentoring contacts with teachers and other adults affected students' college predisposition decisions. While the modified model was an improvement over a previous analysis, results demonstrate that traditional ways of thinking about college predisposition do not hold for these students.
A phylogenetic analysis of lepidosauromorpha

In this paper our primary objective is to analyze phylogenetic relationships within a subtaxon of Sauna, the Lepidosauromorpha (see Addendum, p. 94). Lepidosauromorpha includes the following saiunan diapsids: younginiforms, Paliguana whitei*, Palaeagama vielhaueri*, Saurosternon bainii*, kuehneosaurs, rhynchocephalians, and squamates, all of which are defined and diagnosed below according to our usage. For discussion of the use of the "*," see below. The principal problem in discussing the taxa listed above is that the constitution of Rhynchocephalia and Squamata has not been stable, and that the early archosauromorphs and lepidosauromorphs have been lumped in paraphyletic "Eosuchia. " As part of our analysis of lepidosauromorphs, we attempt to stabilize the concept of each lepidosauromorph taxon with as rigorous a diagnosis as the natiu-e of the material allows. Our analysis provides a relevant series of outgroups for evaluation of character polarity for phylogenetic analysis within Squamata (Estes et al., 1988). In order to give our phylogenetic analysis an explicit basis, we first constructed a minimum step cladogram by hand, using the character set given in Appendix I. The polarities are justified in Sections 2 and 3 by outgroup comparison. We then subjected the data matrix in Appendix II to analysis by the PHYSYS program written by J. S. Farris and installed in the California State University CYBER system. The relatively minor differences between the hand cladogram and that of the computer are analyzed in Appendix III. We have tried to be as explicit as possible in our character descriptions and to give as much discussion of variation as is feasible. Nevertheless, in a paper of this size, we have not been able to discuss the homoplasy in various taxa required by our conclusions in as much detail as we would have preferred.
Accommodation Needs and Student-Environment Fit in Upper Secondary Schools for Students with Severe Physical Disabilities

The purpose of this study was to identify, from the personal perspective of students with disability, their needs for physical and social accommodations in upper secondary schools specially adapted for students with severe physical disabilities. The study also aimed to identify those areas of student-environment fit which were most often achieved. Forty-eight students in four schools in Sweden were assessed by occupational therapists using the School Setting Interview. Forty-seven students reported needs for accommodations in the school setting. The study indicates that schools generally were able to meet the students' accommodation needs in the physical environment. The schools also met students' accommodation needs for field trips, sport activities and assistance. Student-environment fit in occupations requiring reading, remembering and speaking was unsatisfactory. Accommodations on a general, group and individual level are highlighted and discussed. The study recommends that occupational therapists become more involved and offer society their expertise in barrier removal to a greater extent.
Book Review: Reporting for Journalists

discourse (with its attention to power–knowledge–subjectivity dynamics) or a Habermasian model of the public sphere. A more adequate editorial framing and guidance could have encouraged and enabled the various authors to situate their analyses and discussions within a more subtle intellectual debate, and in relation to a more sensitive and complex model of the communicative environment and its socioeconomic and cultural dynamics – or at least to address some of the key issues involved. Ultimately, while the coming together of journalistic and scientific knowledges and analyses is welcome, it remains frustrating that these otherwise understanding and practice-enhancing contributions are not usefully informed by the body of cultural theory and that many are restricted by their uncritical assumption of a limiting social-constructionist perspective.
