A systematic review of the success of sinus floor elevation and survival of implants inserted in combination with sinus floor elevation.

OBJECTIVES The objectives of this systematic review were to assess the survival rate of grafts and implants placed with sinus floor elevation. MATERIAL AND METHODS An electronic search was conducted to identify studies on sinus floor elevation, with a mean follow-up time of at least 1 year after functional loading. RESULTS The search provided 839 titles. Full-text analysis was performed for 175 articles resulting in 48 studies that met the inclusion criteria, reporting on 12,020 implants. Meta-analysis indicated an estimated annual failure rate of 3.48% [95% confidence interval (CI): 2.48%-4.88%] translating into a 3-year implant survival of 90.1% (95% CI: 86.4%-92.8%). However, when failure rates was analyzed on the subject level, the estimated annual failure was 6.04% (95% CI: 3.87%-9.43%) translating into 16.6% (95% CI: 10.9%-24.6%) of the subjects experiencing implant loss over 3 years. CONCLUSION The insertion of dental implants in combination with maxillary sinus floor elevation is a predictable treatment method showing high implant survival rates and low incidences of surgical complications. The best results (98.3% implant survival after 3 years) were obtained using rough surface implants with membrane coverage of the lateral window.
Unsupervised deep feature extraction of hyperspectral images

This paper presents an effective unsupervised sparse feature learning algorithm to train deep convolutional networks on hyperspectral images. Deep convolutional hierarchical representations are learned and then used for pixel classification. Features in lower layers present less abstract representations of data, while higher layers represent more abstract and complex characteristics. We successfully illustrate the performance of the extracted representations in a challenging AVIRIS hyperspectral image classification problem, compared to standard dimensionality reduction methods like principal component analysis (PCA) and its kernel counterpart (kPCA). The proposed method largely outperforms the previous state-of-the-art results on the same experimental setting. Results show that single layer networks can extract powerful discriminative features only when the receptive field accounts for neighboring pixels. Regarding the deep architecture, we can conclude that: (1) additional layers in a deep architecture significantly improve the performance w.r. t. single layer variants; (2) the max-pooling step in each layer is mandatory to achieve satisfactory results; and (3) the performance gain w.r. t. the number of layers is upper bounded, since the spatial resolution is reduced at each pooling, resulting in too spatially coarse output features.
Contextual user experience: how to reflect it in interaction designs?

User experience is highly influenced and even changed by the context in which it occurs. In this SIG session we want to discuss how specific contexts influence various aspects of user experience. So far, both concepts "user experience" and "context" have been discussed a lot to various extent and in different dimensions. With this SIG, we aim to bring both concepts together, highlighting the differences arising from the consideration of different specific contexts and their relevant user experience factors. Thus, we reach a more comprehensive understanding of "contextual user experience", which opens up different roads for research and challenges the HCI community in all design and development phases. We will discuss user experience as focal point of user interface and interaction design bound to specific situational cases.
Mutagenesis and homologous recombination in Drosophila cell lines using CRISPR/Cas9

Summary We have applied the CRISPR/Cas9 system to Drosophila S2 cells to generate targeted genetic mutations in more than 85% of alleles. By targeting a constitutive exon of the AGO1 gene, we demonstrate homozygous mutation in up to 82% of cells, thereby allowing the study of genetic knockouts in a Drosophila cell line for the first time. We have shown that homologous gene targeting is possible at 1–4% efficiency using this system, allowing for the construction of defined insertions and deletions. We demonstrate that a 1 kb homology arm length is optimal for integration by homologous gene targeting, and demonstrate its efficacy by tagging the endogenous AGO1 protein. This technology enables controlled genetic manipulation in Drosophila cell lines, and its simplicity offers the opportunity to study cellular phenotypes genome-wide.
Differential effects of subcutaneous GLP-1 on gastric emptying, antroduodenal motility, and pancreatic function in men.

In this study of eight healthy male volunteers, we investigated the effects of graded doses of subcutaneous glucagon like peptide-1(7-36)amide (GLP-1) on: 1) the gastric emptying pattern of a mixed liquid meal (300 kcal); 2) pancreatic enzyme secretion; 3) antroduodenal motility; and 4) the glycemic response as well as releases of insulin, C-peptide, and glucagon. GLP-1, 0.125 nmol/kg, or 0.25 nmol/kg, or placebo was injected subcutaneously 5 min before meal ingestion. Subcutaneous GLP-1 dose-dependently prolonged the lag period (i.e., the time to reach maximal velocity of gastric emptying) by 46.2% (low dose) and 93.7% (high dose) (p < .05) but left unaltered maximal emptying velocity, total emptying time, and exponential emptying rate. With and without GLP-1, a fed motor pattern was induced by the meal and was terminated by an antral phase III when 98% of the meal had emptied. In parallel to the prolonged lag period, GLP-1 dose-dependently inhibited antral and duodenal motility and coordinated antroduodenal contractions by > 50% (low dose) and > 70% (high dose) (p < .05). GLP-1 initially reduced and thereafter transiently stimulated pancreatic enzyme secretion. This pattern correlated with the prolonged lag period and mirrored the delayed gastric emptying. GLP-1 retarded and diminished the postprandial glucose peak and reduced the total plasma glucose response by 46.6% (low dose) and by 59.4% (high dose) (p < .05). Both doses of GLP-1 delayed the postprandial insulin peak, enhanced total insulin release, and diminished postprandial responses of glucagon and pancreatic polypeptide. The duration of the lag period strongly correlated with the timing of postprandial glucose and insulin peaks (p < .001). The initial delay of gastric emptying, the enhancement of postprandial insulin release, and the inhibition of postprandial glucagon release were independent determinants (p < .01-.05) of the postprandial glucose response after subcutaneous administration of GLP-1.
Analysis of Data Interchange Formats for Interoperable and Efficient Data Communication in Clouds

Efficient mechanisms for data structuring and formatting are indispensable for managing data traffic between and within federated Cloud environments to avoid excessive bandwidth cost and to ensure portability and interoperability. This facilitates provider-agnostic communication, which is essential for interoperable inter-Cloud deployments and portable integration of service components, both with one another and with the underlying Cloud platform. The existing data interchange formats for structuring and serialising data have not yet been analysed in the context of data communication in Clouds. Thus, to address this issue, the determination of an appropriate data interchange format for Clouds is necessary. In this paper, we present a performance analysis of some selected data interchange formats to assess their efficiency in terms of their usability in realising a common messaging format for communicating data in Clouds. We first describe the characteristics of each data format for clear understanding. As a basis for the analysis, we introduce a Cloud use case scenario comprising the transmission of monitored data as messages. The communication means is achieved with a novel message bus system designed to integrate the data interchange formats. We present some evaluations of the formats and compare their compactness for supporting efficient data transmission in Clouds.
Radiation stability of an InGaZnO thin-film transistor in heavy ion radiotherapy

C-axis-aligned crystalline In–Ga–Zn–O (CAAC-IGZO) thin-film transistors (TFTs) have received a great deal of interest for large-area devices owing to their low off-state leak current characteristics and their structural stability as a result of its crystallinity, compared to conventional amorphous TFTs. Here, we report the radiation effects of CAAC-IGZO TFTs in a 12 C 6 + beam irradiation environment, and we discuss prospects for the use of CAAC-IGZO TFTs in heavy-ion radiotherapy. The performance characteristics were investigated by controlling the electrical and size properties in the gate insulator, and the results showed a threshold voltage shift of −1 V and a sub-threshold swing degradation of around 250 mV dec-1 after 130 krad dose irradiation.
The Epistemic View of Belief Merging: Can We Track the Truth?

Belief merging is often described as the process of defining a base which best represents the beliefs of a group of agents (a profile of belief bases). The resulting base can be viewed as a synthesis of the input profile. In this paper another view of what belief merging aims at is considered: the epistemic view. Under this view the purpose of belief merging is to best approximate the true state of the world. We point out a generalization of Condorcet's Jury Theorem from the belief merging perspective. Roughly, we show that if the beliefs of sufficiently many reliable agents are merged then in the limit the true state of the world is identified. We introduce a new postulate suited to the truth tracking issue. We identify some merging operators from the literature which satisfy it and other operators which do not.
Elevated plasma homocysteine is positively associated with age independent of C677T mutation of the methylenetetrahydrofolate reductase gene in selected Egyptian subjects

This study aimed to evaluate the plasma homocysteine (tHcy) and folate levels as well as the methylenetetrahydrofolate reductase (MTHFR) C677T mutation in Egyptian subjects. Fasting total homocysteine (tHcy) and the (MTHFR) C677T mutation were evaluated in 50 healthy young control males (age 35-50 years, Gp1), 50 elderly males age ranged between 50-75 years without any cardiovascular diseases (Gp2) and 50 age matched elderly male patients (Gp3) with myocardial infarction. There was a significant elevation of plasma tHcy in the patients group and Gp2 compared to the young control group (Gp1). The total plasma homocysteine (tHcy) in the control group, Gp2 and the patients group were 17.99 ± 9.76, 39.9 ± 20.06 and 43.8 ± 13.13 μmol/L respectively. The frequency of the TT genotype was 12% in the patient group compared with 8 % in the young healthy controls and elderly subjects (Gp2). The CT genotype constituted 36%, 48% and 44% in the control group, Gp2 and the patients group respectively. There was no significant difference in the occurrence of the TT genotype between the studied groups. Plasma tHcy correlated positively with age, total cholesterol, urea, creatinine, glucose levels and carotid intimal thickness (CIT). Conclusion: The MTHFR mutation does not seem to be associated with either high tHcy or the occurrence of cardiovascular diseases in the studied patients. However, elevated plasma tHcy level positively correlates with age in the studied subjects.
Application of 3D Ray Tracer in WiMAX

WiMAX is a promising technology for a higher spectral efficiency and reliable transmission. This paper compares the downlink throughput experienced by mobile users in a macro-cell in an interference limited scenario with a frequency reuse of one. Bit accurate link level simulations are performed for the downlink physical shared channel (PDSCH). The study is performed for a single antenna system in specific routes at two different carrier frequencies (800 MHz and 2.6 GHz), for two urban environments in the China, and two cell sizes. The paper also considers the carrier aggregation technique which has been proposed since it is difficult to ensure a single wide frequency band for operators. A state-of-the-art 3D ray tracer tool is used to generate 3D channel models for accurate modelling of channel statistics. The study shows that the 800 MHz band has no greater effect on the downlink throughput as compared to 2.6 GHz band, which leads to no additional advantages of inter-band aggregation (considering 800 MHz) compared to intra-band aggregation. It is also observed that a range of speeds can be handled while maintaining good performance in WiMAX. We have clearly shown that the choice of cell size by mobile operators for optimum coverage depends mainly on the propagation characteristic of the environment.
A Platform for Supporting Dynamic Update and Resource Protection in an Embedded Operating System

Recently, many researches focus on providing dynamic update functionality in embedded systems since dynamic update allows a system to enhance or update its functionality even without the need of rebooting the whole system or stopping system services. Dynamic update thus provides more flexibility in the development of embedded systems. However, an incautiously developed component once downloaded may corrupt the system or waste system resources. Because embedded systems’ resources are usually limited, protecting system resources against erroneous components is very important, especially in the systems providing dynamic update. In this paper, we have implemented a platform which supports a remote component update mechanism for dynamically upgrading an embedded operating system at run time. Besides, a system resource protection mechanism is implemented for protecting system resources against downloaded un-trusted components. If our system detects misuses of system resources from an erroneous component, it will reclaim the wasted resources and remove the erroneous component out of our embedded client. Currently, our protection mechanism can reclaim lost memory space, ensure the normal execution of critical sections, and prevent null pointer access. The experimental results demonstrate that our platform can effectively support dynamic remote update and prevent incautiously developed components to misuse system resources with only little extra overhead.
Improved recognition of native‐like protein structures using a combination of sequence‐dependent and sequence‐independent features of proteins

We describe the development of a scoring function based on the decomposition P(structure|sequence) ∝ P(sequence|structure) *P(structure), which outperforms previous scoring functions in correctly identifying native‐like protein structures in large ensembles of compact decoys. The first term captures sequence‐dependent features of protein structures, such as the burial of hydrophobic residues in the core, the second term, universal sequence‐independent features, such as the assembly of β‐strands into β‐sheets. The efficacies of a wide variety of sequence‐dependent and sequence‐independent features of protein structures for recognizing native‐like structures were systematically evaluated using ensembles of ≈30,000 compact conformations with fixed secondary structure for each of 17 small protein domains. The best results were obtained using a core scoring function with P(sequence|structure) parameterized similarly to our previous work (Simons et al., J Mol Biol 1997;268:209–225] and P(structure) focused on secondary structure packing preferences; while several additional features had some discriminatory power on their own, they did not provide any additional discriminatory power when combined with the core scoring function. Our results, on both the training set and the independent decoy set of Park and Levitt (J Mol Biol 1996;258:367–392), suggest that this scoring function should contribute to the prediction of tertiary structure from knowledge of sequence and secondary structure.

Mechanism of REP 27 Protein Action in the D 1 Protein Turnover and Photosystem II Repair from Photodamage [ C ] [ W ] [ OA ]

The function of the REP27 protein (GenBank accession no. EF127650) in the photosystem II (PSII) repair process was elucidated. REP27 is a nucleus-encoded and chloroplast-targeted protein containing two tetratricopeptide repeat (TPR) motifs, two putative transmembrane domains, and an extended carboxyl (C)-terminal region. Cell fractionation and western-blot analysis localized the REP27 protein in the Chlamydomonas reinhardtii chloroplast thylakoids. A folding model for REP27 suggested chloroplast stroma localization for aminoand C-terminal regions as well as the two TPRs. A REP27 gene knockout strain of Chlamydomonas, termed the rep27 mutant, was employed for complementation studies. The rep27 mutant was aberrant in the PSII-repair process and had substantially lower than wild-type levels of D1 protein. Truncated REP27 cDNA constructs were made for complementation of rep27, whereby TPR1, TPR2, TPR1+TPR2, or the C-terminal domains were deleted. rep27-complemented strains minus the TPR motifs showed elevated levels of D1 in thylakoids, comparable to those in the wild type, but the PSII photochemical efficiency of these strains was not restored, suggesting that the functionality of the PSII reaction center could not be recovered in the absence of the TPRmotifs. It is suggested that TPRmotifs play a role in the functional activation of the newly integrated D1 protein in the PSII reaction center. rep27-complemented strains missing the C-terminal domain showed low levels of D1 protein in thylakoids as well as low PSII photochemical efficiency, comparable to those in the rep27 mutant. Therefore, the C-terminal domain is needed for a de novo biosynthesis and/or assembly of D1 in the photodamaged PSII template. We conclude that REP27 plays a dual role in the regulation of D1 protein turnover by facilitating cotranslational biosynthesis insertion (C-terminal domain) and activation (TPR motifs) of the nascent D1 during the PSII repair process.
Beyond Similarity

Agents that provide just-in-time access to relevant online material by observing user behavior in everyday applications have been the focus of much research, both in our lab, and elsewhere. These systems analyze information objects the user is manipulating in order to recommend additional information. Designers of such systems typically make the assumption that objects similar to the one being manipulated by the user will be useful to her. Our own experiments show that users do find many of the documents retrieved by a system of this type are relevant. Yet in the context of a specific task, users find fewer of these documents are useful. Our main point is that in order to make just-in-time information systems truly useful, we need to reexamine the “similarity assumption” inherent in many of these systems’ designs. In light of this, we propose techniques that bring modest amounts of task-specific knowledge to bear in order to perform lexical transformations on the queries these systems perform, thereby ensuring they retrieve not similar documents, but documents that are relevant and useful in purposeful and interesting ways.
The MPEG-7 color layout descriptor: a compact image feature description for high-speed image/video segment retrieval

This paper proposes a color feature description for image and video retrieving applications such as personal video recorder, which manages a large amount of data. This descriptor specifies the spatial distribution of colors with a few nonlinear quantized DCT coefficients of grid based average colors. The tradeoff between the number of the coefficients enclosed in the descriptor and retrieval cost is studied. The experimental results show that the descriptor enclosing six for luminance and three for each chrominance coefficient achieves the best trade-off between the storage cost and retrieval efficiency. It requires 6 bits for DC and 5 bits for AC coefficients, and therefore total storage cost is just 63 bits per image. This description, named color layout descriptor, has been accepted as a part of the MPEG-7 final committee draft.
Particle swarm optimisation and its applications in power converter systems

Particle swarm optimisation PSO algorithm is known for its easy implementation and has been empirically shown to perform well in many optimisation problems. Thus, it is expected to mitigate the computational burden associated with the solutions of non-linear transcendental equations relevant to problems related to power converter systems. This paper starts with an overview of the general concept of PSO and its variants. It then continues with a review on the application of the PSO algorithm in power converter systems. Then, a sample application is described, focusing on the implementation of the harmonic elimination pulse width modulation HEPWM technique on a single-phase inverter circuit. The results of a simulation and experimental work on the inverter operation have revealed that the PSO method employed is capable of accurately calculating the relevant switching angles and generating the gate signals for the inverter power devices and improving its overall system performance.
Support Tool Using Positions of Contents for Voice/Gaze-controlled Browsers

In this paper, we propose a support tool termed Calamari to improve voice/gaze-controlled browsers by using information about the position of contents. It can quickly determine the positions of links, images, and tables in a Web page. Positions in a browser window are important for voice/gaze-controlled browsers to deal with user commands associated with directions, for example, select "upper one" and "left figure. " By using positional information, developers can effectively improve these browsers to use commands along with directions. The proposed tool is implemented in a proxy server; hence, it does not depend on browsers and operating systems. Although it rewrites an HTML document, it does not change the Web page design. We describe two applications using the tool and demonstrate that it is useful for developers to enhance the voice/gaze-controlled browsers.
Time Perception and Dynamics of Facial Expressions of Emotions

Two experiments were run to examine the effects of dynamic displays of facial expressions of emotions on time judgments. The participants were given a temporal bisection task with emotional facial expressions presented in a dynamic or a static display. Two emotional facial expressions and a neutral expression were tested and compared. Each of the emotional expressions had the same affective valence (unpleasant), but one was high-arousing (expressing anger) and the other low-arousing (expressing sadness). Our results showed that time judgments are highly sensitive to movements in facial expressions and the emotions expressed. Indeed, longer perceived durations were found in response to the dynamic faces and the high-arousing emotional expressions compared to the static faces and low-arousing expressions. In addition, the facial movements amplified the effect of emotions on time perception. Dynamic facial expressions are thus interesting tools for examining variations in temporal judgments in different social contexts.
