The prevalence and distribution of nonsyndromic hyperdontia in a group of Qatari orthodontic and pediatric patients

Objective: There is no data specific to the Qatari population on the prevalence and distribution of hyperdontia. The aim of this study was to investigate the prevalence and distribution of hyperdontia in the permanent teeth among a group of Qatari sample and to compare the present results with findings from other populations. Materials and Methods: Records of 1269 Qatari patients (674 females; mean age 11.8 ± 2.3 and 595 males; mean age 11.4 ± 2.2 years) which included panoramic radiographs were examined to identify hyperdontia in the permanent dentition. Supernumerary teeth were assessed for their location, morphology, number, and whether impacted or not. Results: The prevalence of hyperdontia was 1.6% (females 0.7% and males 0.9%;P < 0169). The most common type of supernumerary teeth was the supplemental (45.5%), followed by the conical (40%). Of the supplemental teeth, the mandibular incisor was the most prevalent (60%), followed by the premolar (20%). No significant difference in the prevalence was found between the maxilla and mandible. More than half of supernumerary teeth identified were impacted (54.5%). Conclusions: The prevalence of hyperdontia in a group of Qatari population was within the normal range of the majority of published studies in the literature. Although not significant, hyperdontia cases were more prevalent in male patients.
Civic/citizenship learning and the challenges for democracy in Thailand

After nearly a decade of political polarization and deepening conflicts, Thailand is embarking on yet another cycle of reform and democratization project. While one of the proposed reform and democratizing strategies is to strengthen civic education curriculum and value inculcation, there has been a limited critical understanding on how schools—as important sites for political and cultural socialization—play a role in contributing toward or hindering the construction of citizens for a democracy. This qualitative study examines citizenship learning that takes place through school routines, system, and structure in a ‘democratic’ and an alternative Thai school and the implications for the development of democratic citizens. Findings suggest that civic/citizenship education embedded in everyday’s school practices follows a traditional conception of good citizen and thus provides limited condition for participatory and thoughtful citizenship.
Efficiency of short and long term antimicrobial therapy in transrectal ultrasound-guided prostate biopsies.

OBJECTIVE Prostate biopsy is a frequent diagnostic measure to detect prostatic conditions, including primarily prostate cancer. Its performance does not follow a pattern, mainly regarding preparation for the examination through antimicrobial prophylaxis. The aim of this study is to compare the efficiency of short and long term antimicrobial prophylaxis in transrectal ultrasound-guided prostate biopsies. MATERIALS AND METHODS A clinical study was conducted with a total of 140 patients submitted to prostate biopsy with transrectal ultrasonographic control. Patients were randomly separated in two groups: Group 1 receiving norfloxacin 400mg single dose before the procedure and Group 2 receiving norfloxacin 400mg initiating before the procedure and then bid up to 6 doses. Efficiency control was determined by the incidence of urinary tract infection (UTI) and complications in both groups after statistical analysis. RESULTS The incidence of minor complications in our study was 75%, consistent with data found in the literature. Among the patients with diagnosis of simple UTI, 23% belonged to Group 1 and 8% to Group 2 (p=0.08). Among the patients with complicated UTI, 37% belonged to Group 1 and none belonged to Group 2 (p=0.44). CONCLUSIONS Several advances made transrectal ultrasound-guided prostate biopsies a useful and safe diagnostic tool in the workup of urologic patients. There is no optimal prophylactic preparation to the performance of this procedure. Long term antimicrobial prophylaxis presents a trend toward lower incidence of infectious complications.
Handling asynchronous data in assessing QoS over multiple attributes

The ability to assess the quality of a service (QoS) is important to the emerging SOC paradigm. When multiple providers offer functionally identical services in a SOC environment, it is only natural that consumers should ask how their qualities would compare. While various methods have been proposed to help assess QoS using monitored quality data, they do not handle multiple QoS attributes adequately, especially when the qualities of these attributes are monitored asynchronously. In this paper, we proposed a method that takes both accuracy and confidence into account when assessing QoS over multiple attributes, and employs a kNN based technique to deal with asynchronous data. Our experiments show that the new method can give a more accurate QoS assessment over multiple attributes than existing methods do.
The Zinc-Sensing Mechanism of Mouse MTF-1 Involves Linker Peptides between the Zinc Fingers

ABSTRACT Mouse metal response element-binding transcription factor-1 (MTF-1) regulates the transcription of genes in response to a variety of stimuli, including exposure to zinc or cadmium, hypoxia, and oxidative stress. Each of these stresses may increase labile cellular zinc, leading to nuclear translocation, DNA binding, and transcriptional activation of metallothionein genes (MT genes) by MTF-1. Several lines of evidence suggest that the highly conserved six-zinc finger DNA-binding domain of MTF-1 also functions as a zinc-sensing domain. In this study, we investigated the potential role of the peptide linkers connecting the four N-terminal zinc fingers of MTF-1 in their zinc-sensing function. Each of these three linkers is unique, completely conserved among all known vertebrate MTF-1 orthologs, and different from the canonical Cys2His2 zinc finger TGEKP linker sequence. Replacing the RGEYT linker between zinc fingers 1 and 2 with TGEKP abolished the zinc-sensing function of MTF-1, resulting in constitutive DNA binding, nuclear translocation, and transcriptional activation of the MT-I gene. In contrast, swapping the TKEKP linker between fingers 2 and 3 with TGEKP had little effect on the metal-sensing functions of MTF-1, whereas swapping the canonical linker for the shorter TGKT linker between fingers 3 and 4 rendered MTF-1 less sensitive to zinc-dependent activation both in vivo and in vitro. These observations suggest a mechanism by which physiological concentrations of accessible cellular zinc affect MTF-1 activity. Zinc may modulate highly specific, linker-mediated zinc finger interactions in MTF-1, thus affecting its zinc- and DNA-binding activities, resulting in translocation to the nucleus and binding to the MT-I gene promoter.
Evolutionary stellar population synthesis at high spectral resolution: optical wavelengths

We present the single stellar population (SSP) synthesis results of our new synthetic stellar atmosphere models library with a spectral sampling of 0.3 A, covering the wavelength range from 3000 to 7000 A for a wide range of metallicities (twice solar, solar, half solar and 1/10 solar). The stellar library is composed of 1650 spectra computed with the latest improvements in stellar atmospheres. In particular, it incorporates non-local thermodynamic equilibrium (LTE) line-blanketed models for hot (T eff ≥ 27 500 K), and LTE line-blanketed models (Phoenix) for cool (3000 ≤ T eff ≤ 4500 K) stars. Because of the high spectral resolution of this library, evolutionary synthesis models can be used to predict the strength of numerous weak absorption lines and the evolution of the profiles of the strongest lines over a wide range of ages. The SSP results have been calculated for ages from 1 Myr to 17 Gyr using the stellar evolutionary tracks provided by the Geneva and Padova groups. For young stellar populations, our results have a very detailed coverage of high-temperature stars with similar results for the Padova and Geneva isochrones. For intermediate and old stellar populations, our results, once degraded to a lower resolution, are similar to the ones obtained by other groups (limitations imposed by the stellar evolutionary physics notwidthstanding). The limitations and advantages of our models for the analysis of integrated populations are described. The full set of the stellar library and the evolutionary models are available for retrieval at the websites http://www.iaa. csic.es/∼rosa and http://www.iaa. csic.es/∼mcs/sed@, or on request from the first two authors.
Conflict in later‐life, long‐term marriages

This study provides insight into descriptions of how conflict was experienced by twenty‐five couples who were married 40 years or more. They participated in a face‐to‐face interview regarding their experiences with conflict in the present and their recollections of conflict earlier in their marriage. Two major findings emerged. First, these couples tended to minimize the relevance of conflict in their present stage of life. Second, they reported that present‐day conflict patterns are considerably different from how they managed conflict earlier in their marriage. Two implications of these findings are discussed: Research on communication in later life couples in general needs to acknowledge the importance of life stages, and scholars of marital communication need to question the assumption that couples maintain stable conflict patterns over time.
Twitter and Political Communication in Korea: Are Members of the Assembly Doing What They Say?

Members of the Korean National Assembly post to Twitter, but we really do not know how or what they say on this increasingly popular social media vehicle. We test the Downsian spatial model by asking whether officials communicate in ways which differentiate themselves from members of the opposite party in order to provide a clear distinction when it comes time for individuals to vote. We also compare parties on this strategy and measure the effect on audience size. We discover that there are no inconsistencies between communication and action, which is counter to our expectations. We also find that the popularity of liberal members of the Assembly seems to increase when they provide information rather than attempting to pull the median voter in a leftward direction. There is, thus, little opposition to a continued rightward shift of the median voter.
Towards an emotionally communicative robot : feature analysis for multimodal support of affective touch recognition

Human affective state extracted from touch interaction takes advantage of natural communication of emotion through physical contact, enabling applications like robot therapy [88, 104], intelligent tutoring systems [25], emotionally-reactive smart tech, and more. This work focused on the emotionally aware robot pet context and produced a custom, low-cost piezoresistive fabric touch sensor at 1-inch taxel resolution that accommodates the flex and stretch of the robot in motion. Using established machine learning techniques, we built classification models of social and emotional touch data. We present an iteration of the human-robot interaction loop for an emotionally aware robot [110] through two distinct studies and demonstrate gesture recognition at roughly 85% accuracy (chance 14%). The first study collected social touch gesture data (N=26) to assess data quality of our custom sensor under noisy conditions: mounted on a robot skeleton simulating regular breathing, obscured under fur casings, placed over deformable surfaces. Our second study targeted affect with the same sensor, wherein participants (N=30) relived emotionally intense memories while interacting with a smaller stationary robot, generating touch data imbued with the following: Stressed, Excited, Relaxed, or Depressed. A feature space analysis triangulating touch, gaze, and physiological data highlighted the dimensions of touch that suggest affective state. To close the interactive loop, we had participants (N=20) evaluate researcherdesigned breathing behaviours on 1-DOF robots for emotional content. Results demonstrate that these behaviours can display human-recognizable emotion as perceptual affective qualities across the valence-arousal emotion model [83]. Finally, we discuss the potential impact of a system capable of emotional “conversation” [89] with human users, referencing specific applications.
Experimental Approach to Evaluate the 11C Perfusion and Diffusion in Small Animal Tissues for HadronPET Applications

The development of a reliable dose monitoring system in hadron therapy is essential in order to control the treatment plan delivery. Positron Emission Tomography (PET) is the only method used in clinics nowadays for quality assurance. However, the accuracy of this method is limited by the loss of signal due to the biological washout processes. Up to the moment, very few studies measured the washout processes and there is no database of washout data as a function of the tissue and radioisotope. One of the main difficulties is related to the complexity of such measurements, along with the limited time slots available in hadron therapy facilities. Thus, in this work, we proposed an alternative in vivo methodology for the measurement and modeling of the biological washout parameters without any radiative devices. It consists in the implementation of a point-like radioisotope source by direct injection on the tissues of interest and its measurement by means of high-resolution preclinical PET systems. In particular, the washout of 11C carbonate radioisotopes was assessed, considering that 11C is is the most abundant β+ emitter produced by carbon beams. 11C washout measurements were performed in several tissues of interest (brain, muscle and 9L tumor xenograf) in rodents (Wistar rat). Results show that the methodology presented is sensitive to the washout variations depending on the selected tissue. Finally, a first qualitative correlation between 11C tumor washout properties and tumor metabolism (via 18F-FDG tracer uptake) was found.

Properties of the Intrinsic Flat Distance

Here we explore a variety of properties of intrinsic flat convergence. We introduce the sliced filling volume and interval sliced filling volume and explore the relationship between these notions, the tetrahedral property and the disappearance of points under intrinsic flat convergence. We prove two new Gromov-Hausdorff and intrinsic flat compactness theorems including the Tetrahedral Compactness Theorem. Much of the work in this paper builds upon Ambrosio-Kirchheim's Slicing Theorem combined with an adapted version Gromov's Filling Volume.
Healthcare workers with tuberculosis infected during work

The risk for healthcare workers (HCWs) of tuberculosis (TB) attributable to occupational exposure is difficult to determine, as are the conditions contributing to this risk. The objective of the present study was to determine which TB cases among HCWs in the Netherlands were infected during work and to analyse factors which contributed to infection and subsequent disease. The total study population consisted of 101 cases over a 5-yr period. In 67 (66%) subjects the route of infection could be determined by epidemiological and microbiological information. Of these cases, 28 out of 67 (42%) were due to infection at work, 19 (28%) were community acquired, and 20 (30%) were infected abroad. The 28 cases infected at work were subject to an in-depth analysis. Delayed diagnosis of the index case, especially in the elderly patient, was the main cause of patient-to-HCW transmission. In some circumstances, inadequate infection-control measures also contributed to transmission. In conclusion, a high suspicion of tuberculosis by the clinician, adequate infection control measures by hospital authorities, and early identification of latent tuberculosis infection by occupational and public-health specialists are necessary to prevent tuberculosis among healthcare workers.
Pitch prediction from MFCC vectors for speech reconstruction

The paper proposes a technique for reconstructing an acoustic speech signal solely from a stream of Mel-frequency cepstral coefficients (MFCCs). Previous speech reconstruction methods have required an additional pitch element, but this work proposes two maximum a posteriori (MAP) methods for predicting pitch from the MFCC vectors themselves. The first method is based on a Gaussian mixture model (GMM) while the second scheme utilises the temporal correlation available from a hidden Markov model (HMM) framework. A formal measurement of both frame classification accuracy and RMS pitch error shows that an HMM-based scheme with 5 clusters per state is able to classify correctly over 94% of frames and has an RMS pitch error of 3.1 Hz in comparison to a reference pitch. Informal listening tests and analysis of spectrograms reveals that speech reconstructed solely from the MFCC vectors is almost indistinguishable from that using the reference pitch.
Changes of immunocytochemical localization of vesicular glutamate transporters in the rat visual system after the retinofugal denervation

To clarify which vesicular glutamate transporter (VGluT) is used by excitatory axon terminals of the retinofugal system, we examined immunoreactivities and mRNA signals for VGluT1 and VGluT2 in the rat retina and compared immunoreactivities for VGluT1 and VGluT2 in the retinorecipient regions using double immunofluorescence method, anterograde tracing, and immunoelectron microscopy. Furthermore, the changes of VGluT1 and VGluT2 immunoreactivities were studied after eyeball enucleation. Intense immunoreactivity and mRNA signal for VGluT2, but not for VGluT1 immunoreactivity, were observed in most perikarya of ganglion cells in the retina. Immunoelectron microscopy revealed that VGluT1‐ and VGluT2‐immunolabeled terminals made asymmetrical synapses, suggesting that they were excitatory synapses, and that VGluT1‐immunolabeled terminals were smaller than VGluT2‐labeled ones in many retinorecipient regions, such as the dorsal lateral geniculate nucleus (LGd) and superior colliculus (SC). Double immunofluorescence study further revealed that almost no VGluT2 immunoreactivity was colocalized with VGluT1 in the retinorecipient regions. After wheat germ agglutinin (WGA) injection into the eyeballs, WGA immunoreactivity was colocalized in the single axon terminals of LGd and SC with VGluT2 but not VGluT1 immunoreactivity. After unilateral enucleation, VGluT2 immunoreactivity in the LGd, SC, nucleus of the optic tract, and nuclei of the accessory optic tract in the contralateral side of the enucleated eye was clearly decreased. Although only a small change of VGluT2 immunoreactivity was observed in the contra‐ and ipsilateral suprachiasmatic nuclei, olivary pretectal nucleus, anterior pretectal nucleus, and posterior pretectal nucleus, moderate reduction of VGluT2 was found in these regions after bilateral enucleation. On the other hand, almost no change in VGluT1 immunoreactivity was found in the structures examined in the present enucleation study. Thus, the present results support the notion that the retinofugal pathways are glutamatergic, and indicate that VGluT2, but not VGluT1, is employed for accumulating glutamate into synaptic vesicles of retinofugal axons.

The Journal of Systems and Software

In this paper, we introduce a documentation framework for architecture decisions. This framework consists of four viewpoint deﬁnitions using the conventions of ISO/IEC/IEEE 42010, the new international standard for the description of system and software architectures. The four viewpoints, a Decision Detail viewpoint, a Decision Relationship viewpoint, a Decision Chronology viewpoint, and a Decision Stakeholder Involvement viewpoint satisfy several stakeholder concerns related to architecture decision management. With the exception of the Decision Stakeholder Involvement viewpoint, the framework was evaluated in an industrial case study. The results are promising, as they show that decision views can be created with reasonable effort while satisfying many of the stakeholder concerns in decision documentation.
Mechanical Behavior of Hybrid Composite Phenolic Foam

Hybrid composite phenolic foams are reinforced with chopped glass and aramid fibers in varied proportions. The mechanical properties are measured and compared with those of foams reinforced with only aramid and glass fibers. The compression and shear properties of the hybrid reinforced foams are also compared with those of commercial polyurethane foams. The reinforced hybrid phenolic foams exhibit greater resistance to cracking and are significantly stiffer and stronger than foams with only glass and Nomex® fibers. In general, the mechanical properties of reinforced hybrid phenolic foams are comparable to that of commercial polyurethane foam of equivalent density. The experimentally observed compressive properties (compression modulus) of reinforced phenolic foam with different fiber loading have been compared with existing theories of reinforcement. Composite models such as parallel, series, Halpin—Tsai, and the Hirsch model have been evaluated to fit the experimental data. The findings presented here, coupled with earlier results, demonstrate the potential use of hybrid composite foams as a low-cost engineering material that is tough, strong, and fire retardant.
Hybrid Higher Order FEM-MoM Analysis of Continuously Inhomogeneous Electromagnetic Scatterers

A novel higher order entire-domain finite element technique is presented for accurate and efficient full- wave three-dimensional analysis of electromagnetic structures with continuously inhomogeneous material regions, using large (up to about two wavelengths on a side) generalized curved hierarchical curl-conforming hexahedral vector finite elements (of arbitrary geometrical and field- approximation orders) that allow continuous change of medium parameters throughout their volumes. The results demonstrate considerable reductions in both number of unknowns and computation time of the entire-domain FEM modeling of continuously inhomogeneous materials over piecewise homogeneous models.
