Sinus floor augmentation surgery using autologous bone grafts from various donor sites: a meta-analysis of the total bone volume.

BACKGROUND To date, no studies have been published that evaluated histomorphometric data from a large number of patients while comparing different sites and methods of autologous bone grafting in sinus floor augmentation procedures. A meta-analysis of the English literature from January 1995 till April 2009 was carried out. MATERIALS AND METHODS PubMed search engine and the following journals were explored: Clinical Oral Implant Research, International Journal of Oral and Maxillofacial Implants, International Journal of Periodontics and Restorative Dentistry, and the Journal of Periodontology. RESULTS Out of 147 titles, according to our criteria, 25 articles were left for analysis. The majority were prospective controlled studies (21) and 2 randomized clinical trials, 1 pilot study and 1 case series. A reference value of 47% for total bone volume (TBV) was found while using iliac bone grafting as a standard. Use of intraoral bone grafts increases the TBV, with 11% for chin bone and 14% for bone grafted from other intraoral sites. Particulation of the bone graft has a negative effect on the TBV of 18%. Surprisingly, no correlation between TBV and the time of graft healing was found. Histological section thickness seemed to be a significant variable, as every micron increase of section thickness leads to an increase of 0.4% of TBV. CONCLUSIONS Bone grafting from the iliac crest resulted in a significantly lower TBV compared with intraoral bone grafting. However, due to the limited availability of intraoral bone to be harvested, iliac grafts still have to be considered the gold standard in augmenting the severely atrophic maxilla.

Learning Science in Virtual Reality Multimedia Environments: Role of Methods and Media

College students learned about botany through an agent-based multimedia game. In Experiment 1, students received either spoken or identical on-screen text explanations; in addition, the lesson was presented either via a desktop display (D), a head-mounted display (HMD) used while sitting, or an HMD used while walking (W). In Experiment 2. we examined the effects of presenting explanations as narration (N), text (T), or both (NTj within the D and W conditions. Students scored higher on retention, transfer, and program ratings in N conditions than in T conditions. The NT condition produced results in between. Students gave higher ratings of presence when learning with HMDs, but media did not affect performance on measures of retention, transfer, or program ratings.
Estimation of instantaneous tremor parameters for FES-based tremor suppression

Pathological tremor constitutes the most common movement disorder, and is increasing its prevalence with ageing. Treatment forms range from drugs to surgery in those patients refractory to drugs, however, tremor is not effectively managed in about 25% of patients. According to this, new management techniques such as wearable robots that take advantage of selective biomechanical loading seem an interesting alternative. Our objective is to design robotic exoskeletons which suppress tremor, letting the user perform a voluntary movement, by means of intelligent control approaches that include accurate tremor models. In this context, we propose a two-stage algorithm for real-time estimation of time varying tremor amplitude and frequency. It is based on the assumption that tremor alters voluntary motion in an additive manner, and happens in a higher frequency band. The two-stage algorithm first generates an estimation of voluntary movement based on its inherent slower dynamics, and then removes it from the total motion, directly providing an estimate of tremor. This tremor estimation is then fed into an adaptive filter, which provides instantaneous tremor characteristics. Accurate and robust tremor amplitude and frequency estimates are obtained.
Potentiality for Low Temperature—High Field Application of Iron Chalcogenide Thin Films

Among the various families of Fe-based superconductors, iron chalcogenides, while presenting a transition temperature not particularly high, show great advantages for potential applications at high fields, albeit at liquid helium temperature. In fact, the critical temperature can be increased by stress up to 21 K in thin films, moreover stress can push the critical field up to more than 50 T, and the irreversibility field up to of 45 T. Also critical current densities higher than 1 MA/cm2 can be reached in self field and at 4.2 K, with a very weak dependence on the magnetic field. Interestingly, the JC anisotropy depends on the mode of growth and substrate used. These high values of JC can be achieved without appreciable anisotropy. In this work, we present an overview of Fe(Se0.5Te0.5) thin film deposition by pulsed laser ablation, and a study of their superconducting properties. STM and TEM techniques have been used to characterise structural and morphological properties and, thus, pinning centres. On different substrates the films grow with different types of defects, hence giving totally different JC anisotropy. Our preliminary measurements on a Josephson junction show that in Fe(Se,Te), the JC at the grain boundary is not severely depressed, which makes this material even more interesting from the practical point of view.
Phase order in chaotic maps and in coupled map lattices

By defining a direction phase as the direction of two sequential iterations of the logistic map, a transition of a net direction phase M from zero to a finite value as the parameter &mgr; increases is found. Near the transition point &mgr;(0) a scaling M approximately (&mgr;-&mgr;(0))(alpha) with alpha = 0.5 is obtained. The order state of the direction phases in a coupled map lattice is also studied. A phase synchronization of the direction phases is found although the lattices still remain chaotic.
Female Protection and Empowerment: Travelers Aid Services, 1919-1934

Women's organizations in many early 20th-century communities developed travelers aid (TA) programs to protect and rescue women who were traveling on their own or were strangers to an area and had scant funds for security. This case study of TA services for women in Duluth, Minnesota, at a time when social work was redefining its mission nationally, illustrates the diversity among the female clients' goals, the services they received, and the importance of home in expectations for them.
BDNF Val66Met and cognition: all, none, or some? A meta‐analysis of the genetic association

The Val66Met, G196A (rs6265) polymorphism in the brain‐derived neurotrophic factor gene, BDNF, located at 11p13, has been associated with a wide range of cognitive functions. Yet, the pattern of results is complex and conflicting. In this study, we conducted a meta‐analysis that included 23 publications containing 31 independent samples comprised of 7095 individuals. The phenotypes that were examined in this analysis covered a wide variety of cognitive functions and included indicators of general cognitive ability, memory, executive function, visual processing skills and cognitive fluency. The meta‐analysis did not establish significant genetic associations between the Val66Met polymorphism and any of the phenotypes that were included.
Development of an algorithm for estimating Lead-Acid Battery State of Charge and State of Health

In this paper, a state of charge (SOC) and a state of health (SOH) estimation method for lead-acid batteries are presented. In the algorithm the measurements of battery’s terminal voltage, current and temperature are used in the process of SOC calculation. The thesis was written in cooperation with Micropower AB. The algorithm was designed to fulfill the specific requirements of the electric vehicles application: an error below 5% of SOC, computational simplicity and the possibility of being implemented in a basic programming languages. The current used method at Micropower, Coulomb counting, is compared with a method presented by Chiasson and Vairamohan 2005 based on modified Thevein circuit during charging and discharging of the battery. The Thevenin based method gave better result compared to Coulomb counting but seems not to fulfill Micropowers requirements. A correction method based on periods of no charging or discharging, possible to be used together with Coulomb counting as well as with the Thevenin method was developed. The evaluation method indicates that when using also the correction method the Micropowers requirements are fulfilled.
Intellectual Leadership in Higher Education: Renewing the role of the university professor

and training to higher education. A comparative documentation of ratios of non-traditional educational pathways is excellently provided in table 6.2 and a similar analysis in 6.3. More analysis of table 6.3 could have been provided to interrogate the data before making conclusions. The seventh chapter would have been better written with categories and extent of disability before information on individual students. This is slightly covered on p. 104, ‘Disability as a transitional status’. Cases studied are good to provide evidence-based findings that learners do not have to be locked up in their homes on account of disability. In chapter eight a tough reality is provided, that over and above successes in the preceding one, there are learners who drop out of school, ‘The failed transitions’. This chapter would be better with more interviews and representations of cases that could not make it to higher education. Chapter nine captures time in the broad sense with the use of a critical feminist perspective. Data provided on table 1.1 are consistent with Afrocentric dualism of the use of male and female time with particular reference to African countries like my own, Botswana. In Chapter ten individual and collective identities have a strong relationship in paid work. It would have been interesting for the author to articulate reasons for not giving attention to unpaid work which is often ignored and not globally documented as work in official statistics, and how the two (paid and unpaid work) are disproportionately connected to identities. Chapter eleven reminds the reader that workplaces promote learning across one’s lifespan. Motivational factors in the desire to learn are consistent with andragogical assumptions in the field of adult and continuing education. The penultimate chapter is very balanced in articulating three phases of older workers’ transitions in patterns of employment and work changes. The use of biographies is crucial to depict the life of older adults and how they make transitions after 45 years. It is indeed crucial for older adults to continue learning so that they can develop alternative careers as they move towards retirement or self-employment so that they are not tied to one occupation. The importance of the final chapter is that it knits the 12 previous ones by providing justification or therapeutic suggestions on how to best manage, support, or challenge contemporary experiences of transitions. That transitions have to be closely managed cannot be overemphasized. A positive learning identity, agentic orientations, critical consciousness and narrowing the gap between different stages and contexts are some of the multi-dimensions of closely managing and supporting transitions. Overall, as stated above, this is a very useful contribution to the study of lifelong education.
Mullahs, Martyrs, and Men

A core component of the Islamic Revolution’s ideology was reformulation of gender discourse wrapped around an Islamic hypermasculinity. Attention has been focused on women’s roles and rights in the Islamic Republic, and men are assumed to universally have benefited from the regime’s policies. This hypermasculinity of the Republic has revised prerevolutionary ideals promoting new ideals of manhood. Mullahs are the sage interpreters of the Qur’an and Shari‘at. The young men who bide the dictates of the mullahs and sacrifice themselves for the Republic are martyrs. Then there are the ordinary men. The Shari‘at favors them at the family and civil society, but such a blanket vision ignores the costs paid by all men depending on their social class. High unemployment, inflation, oppression, and rampant drug abuse assail all men. They all pay for gender discrimination against all women in general and women of their social group in particular.
A Method for Identifying Variables for Predicting STEM Enrollment

This research examines demographic, academic, attitudinal, and experiential data from the Cooperative Institutional Research Program (CIRP) for over 12,000 students at two universities to test a methodology for identifying variables showing significant differences between students intending to major in science, technology, engineering, or mathematics (STEM) versus non‐STEM subjects. The methodology utilizes basic statistical techniques to identify significant differences between STEM and non‐STEM students within seven population subgroups based upon school attended, race/ethnicity, and gender. The value of individual variables is assessed by how consistently significant differences are found across the subgroups.
Process consultation, action research, and clinical inquiry : are they the same?

Clarifies a confusion existing in the field of consultation and organization development between formal research and data‐driven inquiry on the one hand and clinical research and client‐driven inquiry on the other. Illustrates the difference between the two approaches by showing the effects of particular approaches to data gathering. Shows how the clinical approach is synonymous with process consultation by being driven by the client′s agenda and argues that the clinical approach is more appropriate for consultation and organization development projects.
Towards Accurate Binary Convolutional Neural Network

We introduce a novel scheme to train binary convolutional neural networks (CNNs) -- CNNs with weights and activations constrained to {-1,+1} at run-time. It has been known that using binary weights and activations drastically reduce memory size and accesses, and can replace arithmetic operations with more efficient bitwise operations, leading to much faster test-time inference and lower power consumption. However, previous works on binarizing CNNs usually result in severe prediction accuracy degradation. In this paper, we address this issue with two major innovations: (1) approximating full-precision weights with the linear combination of multiple binary weight bases; (2) employing multiple binary activations to alleviate information loss. The implementation of the resulting binary CNN, denoted as ABC-Net, is shown to achieve much closer performance to its full-precision counterpart, and even reach the comparable prediction accuracy on ImageNet and forest trail datasets, given adequate binary weight bases and activations.
Adding Maximum Standard Uptake Value of Primary Lesion and Lymph Nodes in 18F-Fluorodeoxyglucose PET Helps Predict Distant Metastasis in Patients with Nasopharyngeal Carcinoma

Objective To find out the most valuable parameter of 18F-Fluorodeoxyglucose positron emission tomography for predicting distant metastasis in nasopharyngeal carcinoma. Methods From June 2007 through December 2010, 43 non-metastatic NPC patients who underwent 18F-Fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) before radical Intensity-Modulated Radiation Therapy were enrolled and reviewed retrospectively. PET parameters including maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean), metabolic tumor volume (MTV), and total lesion glucose (TLG) of both primary tumor and cervical lymph nodes were calculated. Total SUVmax were recorded as the sum of SUVmax of primary tumor and cervical lymph nodes. Total SUVmean, Total MTV and Total TLG were calculated in the same way as Total SUVmax. Results The median follow-up was 32 months (range, 23–68 months). Distant metastasis was the main pattern of treatment failure. Univariate analysis showed higher SUVmax, SUVmean, MTV, and TLG of primary tumor, Total SUVmax, Total MTV, Total TLG, and stage T3-4 were factors predicting for significantly poorer distant metastasis-free survival (p = 0.042, p = 0.008, p = 0.023, p = 0.023, p = 0.024, p = 0.033, p = 0.016, p = 0.015). In multivariate analysis, Total SUVmax was the independent predictive factor for distant metastasis (p = 0.046). Spearman Rank correlation analysis showed mediate to strong correlationship between Total SUVmax and SUVmax-T, and between Total SUVmax and SUVmax-N(Spearman coefficient:0.568 and 0.834;p = 0.000 and p = 0.000). Conclusions Preliminary results indicated that Total SUVmax was an independently predictive factor for distant metastasis in patients of nasopharyngeal carcinoma treated with Intensity-Modulated Radiation Therapy.
A Note on the Reliability and Validity of Suicide Statistics

Doubt about the reliability of official suicide statistics has been noted for over 200 years. Confounding issues include State or religious sanctions; there may be insurance considerations; there is family and community sensitivity about the recording of suicide; different professions are entrusted with the delineation of suicide; and there are differences between clinical and legal definitions of suicide. Systematic studies suggest that official figures provide a valid basis for broad comparisons, but that does not negate the importance of ensuring that suicide data are robust and reliable.
Prediction of active sites for protein structures from computed chemical properties

MOTIVATION Identification of functional information for a protein from its three-dimensional (3D) structure is a major challenge in genomics. The power of theoretical microscopic titration curves (THEMATICS), when coupled with a statistical analysis, provides a method for high-throughput screening for identification of catalytic sites and binding sites with high accuracy and precision. The method requires only the 3D structure of the query protein as input, but it performs as well as other methods that depend on sequence alignments and structural similarities.
Eating Attitudes and Body Satisfaction among Asian and Caucasian Adolescents.

Abstract Recent evidence suggests that Asian adolescents living in the U.K. have unhealthy eating attitudes, compared with Caucasians. This study investigates whether religious affiliation (the Hindu and Muslim faiths) and gender are important factors in explaining that difference. Muslim adolescents had the most characteristic pattern of eating psychopathology, including generally less healthy eating attitudes and behaviours but more favourable scores on a scale assessing body satisfaction. The Muslim boys' eating attitudes were particularly poor relative to those of the other boys. Clinical and research work into ethnic differences in adolescents' eating attitudes should take account of the individual's religious orientation and gender.
The Convergent Validity between Self and Observer Ratings of Personality: A Meta-Analytic Review

The convergent validity between self and observer ratings of the Big Five dimensions of personality was examined by cumulating research findings across studies. The mean correlation corrected for coefficient α in self-ratings and inter-rater reliability in observer ratings was . 46 for agreeableness (N=6359, k=53), . 56 for conscientiousness (N=6754, k=58), . 51 for emotional stability (N=8000, k=55), . 62 for extraversion (N=7725, k=50), and . 59 for openness to experience (N=5333, k=38). Results indicate that, although there is a high degree of construct overlap, both self and observer ratings have substantial unique variance. Moderator effects were analyzed. The duration of acquaintance (strangers vs close relatives) as well as observer type (peers at work vs relatives) were analyzed. Acquaintanceship had a large moderating effect whereas observer type did not moderate the level of convergence.
Male song as a cue for mate choice in the European starling

This study had two aims. First, we looked at individual differences in song characteristics between males of the European starling, and we related song behaviour to factors such as male age, pairing date, polygyny and male breeding success. Second, we experimentally tested whether song has an effect on female mating decisions. 1. During the breeding season, male starlings sing a very long and complex song consisting of a rapid succession of large number of different song types. We observed marked differences between males in average song bout length (a song bout was defined as a period of at least five seconds of song containing no pauses larger than 1.5 seconds) and in song repertoire size. Average song bout lengths ranged from 16 to 35 seconds. The individual repertoire size ranged from 23 to 67 song types. Repertoire size and average song bout length were positively correlated. 2. Both in the field and in captivity, yearling males sang shorter average song bout lengths and had smaller repertoire sizes than older males. 3. Males singing longer average song bouts and having larger repertoire sizes attracted females for pairing before their rivals with shorter average song bouts and smaller repertoire sizes.
Interleukin 6 response to urinary tract infection in childhood.

This study analyzed the interleukin 6 (IL-6) response in 114 children with suspected urinary tract infection (UTI). Urine and serum samples were obtained at the time of enrollment. There were 90 children with UTI, 41 with and 49 without a temperature > or = 38.5 degrees C. The remaining 24 children did not have bacteriuria; 11 were febrile and 13 were not. The urinary IL-6 concentrations were higher in the children with UTI (mean, 129 units/ml) than in the children without bacteriuria (mean, 7 units/ml, P < 0.01). In contrast the serum IL-6 did not differ between children with or without UTI or between children with or without a temperature > or = 38.5 degrees C. The urinary IL-6 response was higher in children who were infected with P fimbriated Escherichia coli than in other children with UTI (P < 0.05). There was a correlation of urinary IL-6 with the degree of proteinuria, hematuria and urinary leukocyte counts (P < 0.001, P < 0.05, P < 0.05, respectively) but not with serum IL-6, CRP or temperature, and of serum IL-6 to C-reactive protein (P = 0.053) and renal concentrating capacity (P < 0.05). The results demonstrate that infections of the urinary tract activate an IL-6 response in children and that the magnitude of the IL-6 response is influenced by the properties of the infecting strain.
