Laser micro-grooved, Arginine-Glycine-Apspartic acid (RGD) coated dental implants, a 5 years radiographic follow-up.

OBJECTIVES This work has utilized laser direct writing to produce 10 microns wide uniform grooves on the surface of custom made titanium (Ti-6Al-4V) dental implants, and the tri-peptide RGD coating to produce a micromechanical and a chemical union with the tissues around the implant crest module and minimize crestal bone loss. The aim of this study was to follow these implants radiographically after five years of service under a mandibular overdenture. METHODOLOGY Standardized digital periapical radiographs and the computer software "Image J" were used to evaluate the bone density profile and vertical bone loss along the mesial and distal sides of the implants used in this study. RESULTS The results of this study demonstrated less vertical bone loss and higher bone density profiles next to the laser microgrooved implants coated with the RGD than those only having the laser micro-grooves. CONCLUSION The RGD coating has improved the bone density profile and reduced the vertical bone loss around the studied dental implants. However, further studies are needed to compare the effects of the laser micro-grooves versus other uniform or non uniform surface features; also, the RGD coating should be compared to other biomimetic surface coating materials.
Campylobacter spp. subtype analysis using gel‐based repetitive extragenic palindromic‐PCR discriminates in parallel fashion to flaA short variable region DNA sequence analysis

Aims: The repetitive extragenic palindromic‐PCR (rep‐PCR) subtyping technique, which targets repetitive extragenic DNA sequences in a PCR, was optimized for Campylobacter spp. These data were then used for comparison with the established genotyping method of flaA short variable region (SVR) DNA sequence analysis as a tool for molecular epidemiology.
Knowledge-based Development: Policy and Planning Implications for Cities

The paper will present a new approach to city development focusing on knowledge-based development. The paper will present a conceptual framework and methodology for defining and assessing a city's knowledge base, i.e. its knowledge resources, knowledge cultures, core competencies and their local and global linkages. The approach draws from the experience of US cities and is being elaborated while undertaking strategic diagnostics of knowledge-based development in several cities for the cities of Amsterdam and Delft, then for the EC-FAST MONITOR study on the Future of European Cities and presently by the city of Vienna. The paper will present key findings from studies of the transformation from production to knowledge in several types and sizes of cities including New York and Cleveland in the US and Amsterdam, Delft, Lille, Lyon, Barcelona, Genoa, Milan and Vienna in Europe. Implications of knowledge-based development for cities and regions will be summarised and the need for a policy framework for cities at the Community level will be explored. Some guiding principles for city development in an open and increasingly knowledge-based global society will be outlined.
Estado de fluxo em praticantes de escalada e skate downhill

Abstract: This study aimed to investigate the prevalence of Flow state in climbing and skate downhill practitioners. The subjects were 37 practitioners. The instruments used were the Sport Motivations Scale (SMS) and Perception Capacity Achievement Task Form. Data collection was performed at the locations of these practice activities. For data analysis it was used the Shapiro-Wilk, Mann-Whitney and Anova one-way. The results showed: 4,54% of climbing practitioners and 13,33% of skate-downhill reached flow state elements; most of practitioners prevailed between the flow phase of anxiety or relaxation and phase of exaltation or control; and the practice time contributed to reach goals and Flow State. It was concluded that the Flow State had low prevalence in practitioners with interference of lack of balance between the perception of the goals, skills and challenges in the adventure activities. Key Words: Sports. Emotions. Perception. Motor performance.
“Money Talks” or “Gender Trumps Money”? Explaining the Division of Unpaid Family Work Among Dual-Earner Parents in an Italian Metropolitan Area

The female employment rate in Western countries has risen dramatically in recent decades, but the division of unpaid family work remains strongly unequal. Clear solutions to this puzzle have proven elusive. This study aims to add new information from Italy to the knowledge concerning the division of domestic activities. To this end, two competing theoretical frameworks are tested, namely the relative resources perspective and the gender role attitudes perspective, using ordinary least-squares regression models. The analysis is based on a well-suited dataset confined to the city of Turin. The predictions from the relative resources perspective are poorly supported, whereas it is very difficult to draw a clear-cut conclusion as regards the gender role attitudes perspective. Further research is required to deepen these results.
Understanding the common principle underlying passive dynamic walking and running

In this study, we discuss the common stabilization mechanism underlying passive dynamic walking (PDW) and passive dynamic running (PDR), focusing on the feedback structures in analytical Poincaré maps. To this end, we have derived linearized analytical Poincaré maps for PDW and PDR, and analyzed these stabilities on two models, namely models with elastic elements and with stiff legs. Through our theoretical analysis, we have found an “implicit two-delay feedback structure”, which can be seen as a certain type of two-delay input digital feedback control developed as an artificial control structure in the field of control theory, is an inherent stabilization mechanism in PDR appearing from the model with elastic elements, and two-period and four-period PDW appearing from with stiff legs. This mechanism is the key to adaptive function underlying phase transition phenomenon between PDW and PDR and period-doubling bifurcation phenomenon in PDW. To the best of our knowledge, this has not yet to be addressed and studied so far. Our results shed new light on the common underlying principle of passive dynamic locomotion, including biped PDW and PDR
OPSM - Opportunistic Power Save Mode for Infrastructure IEEE 802.11 WLAN

We focus on the energy spent in radio communication by the stations (STAs) in an IEEE 802.11 infrastructure WLAN. All the STAs are engaged in web browsing, which is characterized by a short file downloads over TCP, with short duration of inactivity or think time in between two file downloads. Under this traffic, Static PSM (SPSM) performs better than CAM, since the STAs in SPSM can switch to low power state (sleep) during think times while in CAM they have to be in the active state all the time. In spite of this gain, performance of SPSM degrades due to congestion, as the number of STAs associated with the access point (AP) increases. To address this problem, we propose an algorithm, which we call opportunistic PSM (OPSM). We show through simulations that OPSM performs better than SPSM under the aforementioned TCP traffic. The performance gain achieved by OPSM over SPSM increases as the mean file size requested by the STAs or the number of STAs associated with the AP increases. We implemented OPSM in NS-2.33, and to compare the performance of OPSM and SPSM, we evaluate the number of file downloads that can be completed with a given battery capacity and the average time taken to download a file.
A replication function associated with the activation domain of the Epstein-Barr virus Zta transactivator

The Zta transactivator is crucial for both Epstein-Barr virus (EBV) lytic gene expression and lytic DNA replication. We have used a cotransfection-replication assay to examine the effect of mutations in the Zta activation domain (amino acids [aa] 1 to 167) on Zta replication activity. Deletion of Zta aa 25 to 86, which are critical for transcriptional activation of ori-Lyt, or aa 93 to 141 did not adversely affect replication of an ori-Lyt-containing target plasmid. However, removal of aa 2 to 25 (delta2-25) abolished replication activity. Within this subdomain, deletion of aa 2 to 10 (delta2-10) or mutation of codons 18 and 19 (m18/19) or 22 and 26 (m22/26) did not affect replication competency, while deletion of codons 13 to 19 (delta13-19) or mutation at codons 12 and 13 (m12/13) impaired Zta replication function. Each of the replication-negative Zta variants was capable of transactivating expression from both BHLF1 promoter-chloramphenicol acetyltransferase constructions and the BMRF1 promoter on endogenous EBV genomes in Raji cells with efficiency comparable to that of the wild-type polypeptide. Thus, a replication contribution of Zta was functionally separable from its transactivation activity and was supplied by the N-terminal region encompassing aa 11 to 25. Replication by a subset of the impaired Zta mutants was partially rescued upon the addition of Rta to the replication assay. The contribution of Rta mapped to domain II of the Rta activation domain and was specific for this region. A chimeric Rta-EBNA-2 transactivation domain fusion, which retains the DNA-binding and transactivation properties associated with wild-type Rta, failed to rescue replication-deficient Zta. Our data suggest that Rta may act as an ancillary replication factor in EBV ori-Lyt DNA synthesis by stabilizing Zta-replisome interactions.

Validation of a microwave multitone signal with known phase

A validation of the low-band microwave multitone (multisine) signal is presented. This signal consists of a grid of microwave spectral lines with a known phase relation between the spectral lines. Such signals will prove their utility for the calibration of the next generation nonlinear vectorial network analysers operating in narrowband measurement mode.

Oxygen and magnesium abundance in the ultra-metal-poor giants CS 22949-037 and CS 29498-043: Challenges in models of atmospheres

Received; accepted Abstract. We report the results of a non-LTE Fe, O and Mg abundance analysis of the carbon-nitrogen-rich ultra- metal-poor giants CS29498-043 and CS22949-037. The abundance of oxygen has been derived from measurements of the oxygen triplet at 7771-5 u in high resolution spectra obtained with KeckI/HIRES and the forbidden line (O i) 6300 u detected in the TNG/SARG spectra of CS29498-043. Detailed non-LTE analysis of Fe lines has provided reliable stellar parameters which, however, do not resolve the oxygen abundance conflict as derived from the O i 7771-5 u triplet and the (O i) 6300 u forbidden lines. We obtained the following oxygen abundance: for CS22949-037 (O/Fe) =3.13, 1.95; and for CS29498-043; (O/Fe)=3.02, 2.49, based on the O i 7771-5 u triplet and the (O i) 6300 u forbidden line, respectively. A similar conflict appears to exist between the forbidden resonance line Mg i 4571 u and several subordinate lines, such as Mg i 5172 and 5183 u Our analysis demonstrates the failure of standard plane-parallel atmosphere models to describe the physical conditions in the line-forming regions of these ultra-metal-poor giants.
A pilot evaluation of an online cognitive behavioral therapy for insomnia disorder – targeted screening and interactive Web design lead to improved sleep in a community population

Introduction Computerized or online cognitive behavioral therapies (CBTs) are increasingly being developed to deliver insomnia therapy (CBT-i). They seek to address the difficulty of delivering an evidence-based technology to a large number of patients at low cost. Previous online applications have shown significant but variable improvements in sleep efficiency and a decrease in insomnia severity when compared with control groups. The best online methodology remains debated, and there are no such applications currently available within the UK National Health Service. Method Evaluation of treatment outcomes in 75 participants with insomnia disorder using an open-access, novel, interactive online therapy. Rigorous screening was first undertaken to exclude those with probable sleep apnea, restless legs, circadian rhythm disorder, or significant anxiety or depression prior to commencing therapy. A modern interactive video-based website was used to encourage compliance by personalizing therapy based on response. Sleep efficiency, sleep latency, total sleep time, and sleep quality were all assessed prior to and after intervention. Results Of those who accessed therapy, 62% were excluded based on a likely diagnosis of another sleep disorder (788/1281). Participants who completed therapy all had severe insomnia disorder, with a group mean sleep efficiency of 55%. After intervention there was a significant increase in sleep efficiency and sleep latency, with modest nonsignificant improvements in total sleep time. The majority of users reported improved sleep quality, and compliance with therapy was very good, with over 64/75 completing >90% of sleep diary entries. Conclusion Online CBT-i can be designed to deliver personalized therapy with good reported outcomes and high compliance rates in those who start therapy. This initial evaluation also suggests that screening for other sleep disorders and mental health problems is necessary as many other sleep disorders are detected in those who self-refer with insomnia. This would inform the development of any larger-scale applications within the psychological therapies used in the health care system.
A Hybrid of Cooperative Particle Swarm Optimization and Cultural Algorithm for Neural Fuzzy Networks and Its Prediction Applications

This study presents an evolutionary neural fuzzy network, designed using the functional-link-based neural fuzzy network (FLNFN) and a new evolutionary learning algorithm. This new evolutionary learning algorithm is based on a hybrid of cooperative particle swarm optimization and cultural algorithm. It is thus called cultural cooperative particle swarm optimization (CCPSO). The proposed CCPSO method, which uses cooperative behavior among multiple swarms, can increase the global search capacity using the belief space. Cooperative behavior involves a collection of multiple swarms that interact by exchanging information to solve a problem. The belief space is the information repository in which the individuals can store their experiences such that other individuals can learn from them indirectly. The proposed FLNFN model uses functional link neural networks as the consequent part of the fuzzy rules. This study uses orthogonal polynomials and linearly independent functions in a functional expansion of the functional link neural networks. The FLNFN model can generate the consequent part of a nonlinear combination of input variables. Finally, the proposed FLNFN with CCPSO (FLNFN-CCPSO) is adopted in several predictive applications. Experimental results have demonstrated that the proposed CCPSO method performs well in predicting the time series problems.
Skip-Thought Vectors

We describe an approach for unsupervised learning of a generic, distributed sentence encoder. Using the continuity of text from books, we train an encoder-decoder model that tries to reconstruct the surrounding sentences of an encoded passage. Sentences that share semantic and syntactic properties are thus mapped to similar vector representations. We next introduce a simple vocabulary expansion method to encode words that were not seen as part of training, allowing us to expand our vocabulary to a million words. After training our model, we extract and evaluate our vectors with linear models on 8 tasks: semantic relatedness, paraphrase detection, image-sentence ranking, question-type classification and 4 benchmark sentiment and subjectivity datasets. The end result is an off-the-shelf encoder that can produce highly generic sentence representations that are robust and perform well in practice.
Hairy Goals in Change Management: The Case of Implementing ICT-Supported Task Planning in a Hospital Setting

Abstract The technological development in health communication systems changes premises for information flow and task planning to provide the patients the best possible treatment. The purpose of this paper is to examine the role of hairy goals in the implementation of an advanced information and communication technology (ICT) task planning system in a hospital setting. The study is based on a qualitative, single instrumental case study. Forty-six in-depth interviews with employees from four different hospitals were carried out. Hairy goals had a unifying effect on employees from different professions and subcultures within the hospitals in the implementation of the new ICT-supported advanced task planning system. An agile project style in the first phase of the implementation caused some frustration, but was solved by self-organization and locally set learning goals. Our findings revealed a gap between the hairy goals set by the top management and the time it took for the self-organizing change principles of agile management to set in. This study indicates that goal-setting procedures should match the phases of the change process.
Characterization of integrin engagement during defined human embryonic stem cell culture

Human embryonic stem (hES) cells are pluripotent, capable of differentiating into any cell type of the body, and therefore have the ability to provide insights into mechanisms of human development and disease, as well as to provide a potentially unlimited supply of cells for cell‐based therapy and diagnostics. Knowledge of the adhesion receptors that hES cells employ to engage extracellular matrix (ECM) proteins is of basic biological interest and can enhance the design of cell culture and implantation systems to enable these biomedical applications. Although hES cells express a variety of cell surface receptors, little is known about which integrins are involved during subculture and passage. Matrigel is broadly used as a cell adhesive matrix for hES cell culture. Here, we sought to identify which integrins hES cells exploit for adhesion to Matrigel‐coated surfaces in defined medium conditions. Using RT‐PCR, flow cytometry, and fluorescence immunochemistry, we found that numerous integrins were expressed by H1 hES cells;however, antibody blocking assays indicated that only αvβ3, α6, β1, and α2β1 played a significant role in the initial adhesion of the hES cells to Matrigel in defined medium conditions. We subsequently identified a cohort of synthetic peptides that, when adsorbed to the culture surface, promoted H1 hES cell attachment and proliferation, as well as maintained a pluripotent phenotype. Peptides designed to engage with αvβ3, α6, β1, and α2β1 integrins and syndecan‐1 were tested both individually and in various combinations. A combination of two integrinengaging peptides (AG‐10, C‐16) and one syndecanengaging peptide (AG‐73) was sufficient to promote hES cell adhesion, maintenance, and proliferation. We propose that a specific integrin “fingerprint” is necessary for maintenance of hES cell self‐renewal, and synthetic culture systems must capture this engagement profile for hES cells to remain undifferentiated. — Meng, Y. , Eshghi, S. , Li, Y.

INDIVIDUAL DIFFERENCES IN INTERVIEWER RATINGS: THE IMPACT OF STANDARDIZATION, CONSENSUS DISCUSSION, AND SAMPLING ERROR ON THE VALIDITY OF A STRUCTURED INTERVIEW

This research investigated empirical issues regarding the validity of individual interviewers’(N= 62) ratings collected after a structured interview. Each interviewer rated an average of 25 interviewees. One hypothesis examined but not supported was that systematic interviewer errors will attenuate interview validity when data are aggregated across interviewers. Also investigated was the validity of ratings averaged across interviewers compared to consensus ratings; consensus ratings were shown to have significantly but probably not practically higher validities. Third, a meta-analysis of individual interviewer validities revealed that all of the variance in validities could be attributed to sampling error. Results and implications are discussed.
