Investigation of the High Mobility IGZO Thin Films by Using Co-Sputtering Method

High transmittance ratio in visible range, low resistivity, and high mobility of IGZO thin films were prepared at room temperature for 30 min by co-sputtering of Zn2Ga2O5 (Ga2O3 + 2 ZnO, GZO) ceramic and In2O3 ceramic at the same time. The deposition power of pure In2O3 ceramic target was fixed at 100 W and the deposition power of GZO ceramic target was changed from 80 W to 140 W. We chose to investigate the deposition power of GZO ceramic target on the properties of IGZO thin films. From the SEM observations, all of the deposited IGZO thin films showed a very smooth and featureless surface. From the measurements of XRD patterns, only the amorphous structure was observed. We aimed to show that the deposition power of GZO ceramic target had large effect on the Eg values, Hall mobility, carrier concentration, and resistivity of IGZO thin films. Secondary ion mass spectrometry (SIMS) analysis in the thicknesses’ profile of IGZO thin films found that In and Ga elements were uniform distribution and Zn element were non-uniform distribution. The SIMS analysis results also showed the concentrations of Ga and Zn elements increased and the concentrations of In element was almost unchanged with increasing deposition power.
Social Vulnerability and Traumatic Dental Injury among Brazilian Schoolchildren: A Population-Based Study

The aim of the present study was to test the association between social vulnerability and the prevalence of traumatic dental injury (TDI). A population-based cross-sectional study was carried out with 1,556 schoolchildren aged 11 to 14 years in the city of Belo Horizonte, Brazil. The participants were examined for TDI using Andreasen’s criteria and those diagnosed with TDI were interviewed to determine the history of the injury. The Social Vulnerability Index (SVI) was used for socioeconomic classification, which addresses environmental, cultural, economic, legal and security/survival dimensions. The Poisson regression model was used for the multivariate analysis, with the significance level set at 5%. The prevalence of TDI was 14.1%; 59.3% of the participants with TDI did not seek a dentist after the incident. Poorer environmental, economic and legal conditions were statistically associated with the occurrence of untreated TDI (p < 0.05) and all the five SVI dimensions were associated with seeking a dentist due to TDI (p < 0.006). The prevalence of untreated TDI was higher among boys (PR: 1.42; 95%CI: 1.11–1.81) and those in situations of greater social vulnerability (PR: 2.27; 95%CI: 1.11–4.61). In conclusion, the male gender and high social vulnerability proved to be associated with the occurrence of TDI.
Criminal Thought Content and Criminal Thought Process as Mediators of Peer Influence

The purpose of this study was to determine whether measures of criminal thought content and criminal thought process are capable of mediating the peer influence effect. Participants were all 1,725 (918 boys and 807 girls) members of the National Youth Survey. The average age of the participants was 13.87 years at initial contact. In this study, attitudes toward deviance served as a measure of criminal thought content, proactive criminal thinking served as a measure of criminal thought process, and the lagged delinquent peers–offending relationship marked the peer influence effect. Path analysis was conducted with structured equation modeling and demonstrated that criminal thought content and criminal thought process, both individually and conjointly, mediated the peer influence effect. There was no evidence that these effects were moderated by gender. A principal implication of these results is that criminal thought content and criminal thought process are both instrumental in mediating the effect of peer deviance on participant delinquency. In addition, criminal thought content and criminal thought process appear to be learned through association with deviant peers while providing nonredundant and largely additive variance to predictions of subsequent offending via their ability to link prior delinquent peer associations to future offending behavior.
Comparison by objective parameters in patients with chronic rhinosinusitis managed medically and surgically (with and without powered instruments)

Objective To compare mucociliary clearance time and quality of life in patients who underwent sinus surgery using conventional and powered instruments, and in patients who were treated nonsurgically. Methods A total of 151 patients with chronic rhinosinusitis were included. Fifty-four patients were treated conservatively, 48 patients were managed surgically by using conventional instruments and 49 patients were managed by using a microdebrider. Kupferberg nasal endoscopy grades, 20-item Sino-Nasal Outcome Test scores, Lund-Mackay scores, and mucociliary clearance time were analyzed. Results On comparison among the groups, it was found that there was a significant difference between group A (nonsurgically treated) compared with group B (surgery by conventional means) or group C (surgery with microdebrider) in nasal endoscopic grades, Lund-Mackay scores, 20-item Sino-Nasal Outcome Test scores, and mucociliary clearance time. However, in comparison between groups B and C, there was no statistically significant difference. Conclusion Mucociliary clearance time tended to recover after starting treatment for chronic rhinosinusitis both after conservative treatment and after surgical treatment. Surgery provided better improvement in different objective scores in chronic rhinosinusitis. There exists no statistical difference in parameters independent of the instrument used for surgery.
Detection of Helicobacter Pylori in Bronchoalveolar Lavage of Patients With Chronic Obstructive Pulmonary Disease by Real Time Polymerase Chain Reaction

BACKGROUND Chronic obstructive pulmonary disease (COPD) is one of the most important causes of disability and mortality in the world. Although cigarette smoking and environmental pollutants have been recognized as the major causes of COPD, the role of infection in the pathogenesis and progression of COPD has also been reported. OBJECTIVES The aim of the present study was to find the relationship between Helicobacter Pylori infection and COPD through anti H. pylori IgG serology, real time PCR of bronchoalveolar lavage and trans bronchial biopsy urease tests. PATIENTS AND METHODS This descriptive cross-sectional study was carried out on 60 adults with COPD. After obtaining the patient's history, physical examination, spirometry and confirmation of COPD diagnosis by pulmonologist, subjects were selected through convenience sampling. In order to determine the severity and prognosis of disease, the global initiative for chronic obstructive lung disease (GOLD) criteria and BODE index were used. Subjects underwent bronchoscopy for obtaining bronchoalveolar lavage (BAL) samples and biopsy was performed. Biopsy and BAL samples were investigated respectively by urease test and real time PCR. Moreover, patients' serum samples were serologically studied for detection of anti H. pylori IgG. RESULTS Mean age of the participants was 60.65 ± 9.15 years, and 25% were female and 75% were male. The prevalence rate of H. pylori in COPD patients was 10% according to real time PCR, 88.3% according to the serology test and 0% based on the urease test. According to the results of PCR and considering the severity of disease based on the GOLD criteria, from those with a positive PCR, one patient (16.6%) had very severe obstruction, three (50%) had severe obstruction and two patients (33.3%) had moderate obstruction. The relationship between H. pylori presence (based on PCR) and disease severity and prognosis was not statistically significant. CONCLUSIONS These findings can justify the hypothesis of direct injury and chronic inflammation via inhalation and aspiration resulting in H. pylori colonization. In fact, it is thought that H. Pylori infection, beside the host genetic vulnerability and other environmental risk factors might make the patient susceptible to COPD or lead to COPD worsening. Although we found H. pylori infection in some patients with COPD, the results of this study, could not explain the pathogenic mechanisms of COPD.
Local Interstellar Medium Kinematics towards the Southern Coalsack and Chamaeleon-Musca dark clouds

The results of a spectroscopic programme aiming to investigate the kinematics of the local interstellar medium components towards the Southern Coalsack and Chamaeleon-Musca dark clouds are presented. The analysis is based upon high-resolution (R � 60 000) spectra of the insterstellar NaI D absorption lines towards 63 B-type stars (d 6 500 pc) selected to cover these clouds and the connecting area defined by the Gala ctic coordinates: 308 ◦ > l > 294 ◦ and 22 ◦ 6 b 6 5 ◦ . The radial velocities, column densities, velocity disper sions, colour excess and photometric distances to the stars are used to understand the kinematics and distribution of the interstellar cloud components. The ana lysis indicates that the interstellar gas is distributed in two extended sheet-like structures perme ating the whole area, one at d 6 60 pc and another around 120-150 pc from the Sun. The nearby feature is approaching to the local standard of rest with average radial velocity of 7 km s −1 , has low average column density log NNa I � 11.2 cm −2 and velocity dispersion b � 5 km s −1 . The more distant feature has column densities between 12.3 6 log NNa I 6 13.2, average velocity dispersion b � 2.5 km s −1 and seems associated to the dust sheet observed towards the Coalsack, Musca and Chamaeleon direction. Its velocity is centered around 0 km s −1 , but there is a trend for increasing from 3 km s −1 near b = 1 ◦ to 3 km s −1 near b = 18 ◦ . The nearby low column density feature indicates a general outflow from the Sco-Cen association, in aggreement with several independent lines of data in the general searched direction. The dust and gas feature around 120 ‐ 150 pc seem to be part of an extended large scale feature of similar kinematic properties, supposedly identified with the interaction zon e of the Local and Loop I bubbles. Assuming that the interface and the ring-like volume of dense neutral matter that would have been formed during the collision of the two bubbles have similar properties, our results rather suggest that the interaction zone between the bubbles is twisted and folded.
Extremely red galaxies: age and dust degeneracy solved?

The extremely red galaxies (ERGs) are defined in terms of their very red optical-to-near IR colours (as R−K>5 or I−K>4). Originally this selection was aimed at selecting old (>1 Gyr) passively evolving elliptical galaxies at intermediate redshift (1<z<2), but it was soon discovered that young star-forming dusty galaxies can show similar colours and therefore be selected in the same surveys. It is crucial to distinguish between these two populations because they have very different consequences on the models of galaxy formation. Here we show that old ellipticals and dusty starbursts are expected to show different colours in the (I−K) versus (J−K) diagram for redshift range 1<z<2, thus providing a useful tool to classify ERGs in large samples up to K<20. This is mainly owing to the fact that old galaxies at these redshifts have a strong 4000-A break at λ<1.2 μm (J band), while dusty galaxies show smoother spectral energy distributions and therefore redder J−K colours. We discuss this difference in detail both in the framework of the stellar population synthesis models and by using observed spectra. The selection criterion is also compared with the properties of ERGs of known nature. We also show that this colour selection criterion is also useful to separate the ERGs from brown dwarf stars showing similar optical-to-IR colours.
Perfectionism and time perspectives: An inquiry into the association between perfectionism subtypes and categorical time perspectives

The present study investigated the previously unexplored association between the perfectionistic personality dimensions, as defined by the 2 × 2 model of perfectionism, and individual time perspectives. The study tested the relationship between pure self-oriented, pure socially prescribed, mixed and non-perfectionist subtypes and individual time perspectives, using a sample of 129 undergraduate students with a mean age of 19.84 (SD = 4.60). Participants completed a one-time evaluation using the short versions of the Hewitt and Flett Multidimensional Perfectionism Scales and of the Zimbardo Time Perspectives Inventory. Following moderated hierarchical multiple regression analysis, the main result was discovering evidence of a close association between present fatalism and perfectionistic subtypes. Furthermore, pure self-oriented perfectionism consistently predicted more adaptive outcomes in terms of time perspectives as compared to non-perfectionism in four out of the five time perspectives, supporting the emerging empirical distinction between adaptive and maladaptive perfectionism. The study’s overall results indicate that pure self-oriented perfectionism may hold more adaptive merit than non-perfectionism in the case of time perspectives and that present fatalism may hold a close association with the perfectionistic variable.
Dynamic Nonprehensile Manipulation for Rotating a Thin Deformable Object: An Analogy to Bipedal Gaits

A rigid plate end-effector at the tip of a high-speed manipulator can remotely manipulate an object without grasping it. This paper discusses a dynamic nonprehensile manipulation strategy to rotate thin deformable objects on a rigid plate with two degrees of freedom (DOFs). The deformation of the object due to dynamic effects is exploited to produce fast and stable rotation. By varying the frequency of the rotational component of the plate's motion, we show that the dynamic behavior of the object mimics either a sliding, walking, or running gait of a biped. We introduce a model to simulate this type of system in which the object is constructed of multiple nodes that are connected by viscoelastic joint units with three DOFs. The joint's viscoelastic parameters are estimated experimentally in order to model real food. Afterward, simulation analysis is used to investigate how the object's rotational behavior and its angular velocity change with respect to the plate's motion frequency. We show how the object's behavior during rotation is analogous to bipedal sliding, walking, and running gaits and then obtain optimal plate motions leading to the maximal angular velocity of the object. We also reveal that an appropriate angular acceleration of the plate is essential for a dynamically stable and fast object's rotation. We further show that the friction coefficient that maximizes the object's angular velocity depends on its gait.
Electrostatic polarization is critical for the strong binding in streptavidin‐biotin system

The origin of strong affinity of biotin and its analogs binding to (strept)avidin is still the subject of an ongoing controversy. In this work, thermodynamic integration is carried out to study of the difference of binding free energies between biotin and iminobiotin to streptavidin. Three atomic charge schemes are implemented and compared. One is the traditional AMBER charge, and the other two, termed the polarized protein‐specific charge, are based on a linear scaling quantum mechanical method and a continuous solvation model and have polarization effect partially or fully included. The result indicates that when nonpolarized AMBER force field is applied, the result is much underestimated. When electronic polarization is gradually included, the difference of binding affinity increases along with it. Using the linear‐response approximation to eliminate the error in self‐charging process, the corrected binding affinity agrees well with the experimental observation. This study is direct evidence indicating that polarization effect is critical for the strong binding in streptavidin‐biotin system. © 2012 Wiley Periodicals, Inc.
Estimating soil salinity over a shallow saline water table in semiarid Tunisia.

Rapid and reliable observations of soil electrical conductivity are essential in order to maintain sustainable irri- gated agriculture. Direct measurement of the electrical conductivity of saturated soil paste (ECe), however, is tedious and time consuming. Therefore, there are needs to find efficient indirect methods to predict the soil salinity from other readily available observations. In this paper we explore the application of multiple linear regression (MLR) and artificial neural networks (ANN) to predict ECe variation from easily measured soil and groundwater properties under highly complex and heterogeneous field conditions in semiarid Tunisia. We compare two methods for dividing the data set into training and validation sub-sets; a statistical (SD) and a random data set division (RD), and their effect on model performance. The in- put variables were chosen from the plot coordinates, groundwater table properties (depth, electrical conductivity, pie- zometric level), and soil particle size at 5 depths. The results obtained with ANN and MLR indicate that the statistical properties of data in the training and validation sets need to be taken into account to ensure that optimal model perform- ance is achieved. The SD can be considered as a solution to resolve the problem of over-fitting a model when using ANN. For the SD, the determination coefficient (R 2 ) when using an ANN model varied from 0.85 to 0.88 and the root mean square error from 1.23 to 1.80 dS m -1 . Because of the complexity of the field soil salinity process and the spatial variabil- ity of the data, this clearly indicates the potential to use ANN models to predict ECe.
DNA barcoding to identify leaf preference of leafcutting bees

Leafcutting bees (Megachile: Megachilidae) cut leaves from various trees, shrubs, wildflowers and grasses to partition and encase brood cells in hollow plant stems, decaying logs or in the ground. The identification of preferred plant species via morphological characters of the leaf fragments is challenging and direct observation of bees cutting leaves from certain plant species are difficult. As such, data are poor on leaf preference of leafcutting bees. In this study, I use DNA barcoding of the rcbL and ITS2 regions to identify and compare leaf preference of three Megachile bee species widespread in Toronto, Canada. Nests were opened and one leaf piece from one cell per nest of the native M. pugnata Say (N=45 leaf pieces), and the introduced M. rotundata Fabricius (N=64) and M. centuncularis (L.) (N=65) were analysed. From 174 individual DNA sequences, 54 plant species were identified. Preference by M. rotundata was most diverse (36 leaf species, H′=3.08, phylogenetic diversity (pd)=2.97), followed by M. centuncularis (23 species, H′=2.38, pd=1.51) then M. pugnata (18 species, H′=1.87, pd=1.22). Cluster analysis revealed significant overlap in leaf choice of M. rotundata and M. centuncularis. There was no significant preference for native leaves, and only M. centuncularis showed preference for leaves of woody plants over perennials. Interestingly, antimicrobial properties were present in all but six plants collected; all these were exotic plants and none were collected by the native bee, M. pugnata. These missing details in interpreting what bees need offers valuable information for conservation by accounting for necessary (and potentially limiting) nesting materials.
Integrating a Location-Based Mobile Game in the Museum Visit

Location-based systems currently represent a suitable solution to enhance cultural experiences inside museums, as they can satisfy visitors’ needs through the provision of contextualized contents and services. In this framework, a promising approach to captivate the attention of teenagers—a hard to please target audience—is represented by mobile serious games, such as playful activities aiming to primarily fulfil educational purposes. The use of a mobile digital tool during the visit definitely discloses new opportunities for contextual learning scenarios; however, so far, only a few studies have analysed the impact of different communication approaches on visitors’ degree of exploration and acquisition of knowledge. This work aims to enrich this field of research, presenting the conceptual framework; the design principles; and the evaluation results of “Gossip at palace,” a location-based mobile game integrating a storytelling approach. The game was developed for an Italian historical residence to communicate its 18th-century history to teenagers, capitalizing on narrative and game mechanics to foster young visitors’ motivations to explore the museum and facilitate their meaning-making process. Following a mixed-methods perspective, the article firstly describes to what extent the components of the application were appreciated by teenagers as well as by other visitor segments. Secondly, it provides an insight on the effectiveness of the game in facilitating the acquisition of historical knowledge by participants, enriched by considerations on the methods to be adopted when evaluating mobile learning in informal educational settings. Thirdly, players’ degree of use of the digital game throughout the visit is compared to analogous patterns registered for people using a multimedia mobile guide in the same venue. On the one hand, the study pointed out that the game facilitated a wider exploration of the museum; on the other, it highlighted that players mainly gained a superficial knowledge of the proposed contents.
