Alloplastic Mandibular Reconstruction: A Systematic Review and Meta-Analysis of the Current Century Case Series

Background: Alloplastic mandibular reconstruction remains insufficiently predictable, with no systematic reviews to assess its scope and limitations. Methods: The PubMed, CINAHL, EMBASE, and Web of Science databases were searched for English study reports, published in the current century, of mere alloplastic surgical reconstruction of mandibular ablative defects. Results: In 14 articles, there were 944 patients, with a median age of 58.7 years (interquartile range, 53.2 to 62 years); 58.7 percent (interquartile range, 66.7 to 78.6 percent) were male. Cases of squamous cell carcinoma per study constituted 93.5 percent (interquartile range, 81.5 to 100 percent). Defects were mostly lateral (Boyd classification) (60.5 percent; interquartile range, 56.2 to 62 percent) and received mostly conventional bridging plates (in 64.3 percent of the studies) and pedicled flaps (45.3 percent; interquartile range, 37.1 to 58.3 percent); 60.7 percent (interquartile range, 53.5 to 58.8 percent) received adjuvant therapy. At 32-month follow-up, the complication and failure rates were 40.1 percent (interquartile range, 26.7 to 58.6 percent) and 30.8 percent (interquartile range, 11.7 to 48.1 percent), respectively. The overall survival rate was 55 percent (interquartile range, 27.8 to 74 percent). Radiotherapy seemed to be a relative risk factor for complications (1.387; p = 0.014) and plate loss (1.585; p = 0.006). Crossing the midline seemed to be a relative risk factor for plate exposure (1.533; p = 0.000) and overall complications (1.385; p = 0.002). Conclusions: The results should be generalized cautiously. Alloplastic reconstructive surgery faces a remarkable lack of evidence. Relatively high complication and failure rates are areas of further concern.
Effect of extracellular Ca++ omission on isolated hepatocytes. I. Induction of oxidative stress and cell injury.

The effect of varying extracellular Ca++ concentration and various antioxidants and metal ion chelators on the viability of isolated rat hepatocytes incubated under 95% O2-5% CO2 was evaluated. Decreasing the extracellular Ca++ concentration from 2 mM to 50 microM or less resulted in a progressive increase in cell injury as determined by lactate dehydrogenase (LDH) leakage. The generation of an oxidative stress, indicated by malondialdehyde formation, occurred before and concomitant with LDH leakage. The antioxidants vitamin E, N,N'-diphenyl-p-phenyl-enediamine, chlorpromazine and promethazine, as well as the iron chelators desferrioxamine and EDTA, all prevented both malondialdehyde production and LDH leakage induced by the absence of extracellular Ca++. A marked loss of cytosolic and mitochondrial glutathione was observed in cells incubated without Ca++, which could be significantly prevented by antioxidants and iron chelators. Similar effects on hepatocyte vitamin E levels also were noted. Addition of the Ca++ chelator ethylene glycol bis(beta-aminoethyl ether)-N,N'-tetraacetic acid to the incubation medium totally prevented LDH leakage and malondialdehyde production and partially ameliorated glutathione and vitamin E loss. Conversely, cell injury resulting from disrupted cellular Ca++ homeostasis after treatment with the Ca++ ionophore A23187 plus 2 mM Ca++ was only slightly inhibited by antioxidants and iron chelators. However, ethylene glycol bis(beta-aminoethyl ether)-N,N'-tetraacetic acid also prevented A23187-induced cell injury. These results indicate that a decrease in extracellular Ca++ generates an oxidative stress in hepatocytes which leads ultimately to severe cell injury. This oxidative stress appears to be a Ca++-dependent phenomenon, precipitating all toxicity by a mechanism distinct from that induced by A23187 treatment. (ABSTRACT TRUNCATED AT 250 WORDS)
Equal charge black holes and seven-dimensional gauged supergravity

We present various supergravity black holes of different dimensions with some charges set equal in a simple, common form. Black hole solutions of seven-dimensional gauged supergravity with three independent angular momenta and two equal charges are obtained. We investigate the thermodynamics and the BPS limit of this solution, and find that there are rotating supersymmetric black holes without naked closed timelike curves. There are also supersymmetric topological soliton solutions without naked closed timelike curves that have a smooth geometry.
amoA Gene Abundances and Nitrification Potential Rates Suggest that Benthic Ammonia-Oxidizing Bacteria and Not Archaea Dominate N Cycling in the Colne Estuary, United Kingdom

ABSTRACT Nitrification, mediated by ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA), is important in global nitrogen cycling. In estuaries where gradients of salinity and ammonia concentrations occur, there may be differential selections for ammonia-oxidizer populations. The aim of this study was to examine the activity, abundance, and diversity of AOA and AOB in surface oxic sediments of a highly nutrified estuary that exhibits gradients of salinity and ammonium. AOB and AOA communities were investigated by measuring ammonia monooxygenase (amoA) gene abundance and nitrification potentials both spatially and temporally. Nitrification potentials differed along the estuary and over time, with the greatest nitrification potentials occurring mid-estuary (8.2 μmol N grams dry weight [gdw]−1 day−1 in June, increasing to 37.4 μmol N gdw−1 day−1 in January). At the estuary head, the nitrification potential was 4.3 μmol N gdw−1 day−1 in June, increasing to 11.7 μmol N gdw−1 day−1 in January. At the estuary head and mouth, nitrification potentials fluctuated throughout the year. AOB amoA gene abundances were significantly greater (by 100-fold) than those of AOA both spatially and temporally. Nitrosomonas spp. were detected along the estuary by denaturing gradient gel electrophoresis (DGGE) band sequence analysis. In conclusion, AOB dominated over AOA in the estuarine sediments, with the ratio of AOB/AOA amoA gene abundance increasing from the upper (freshwater) to lower (marine) regions of the Colne estuary. These findings suggest that in this nutrified estuary, AOB (possibly Nitrosomonas spp.) were of major significance in nitrification.

Global state-dependent QoE based routing

For years, wireless network systems have been trying to satisfy end-users and support high quality multimedia applications such as Mobile TV, VoIP, etc. Combining wireless networks with multimedia content distribution needs efficient routing protocols. We develop in this paper a new routing protocol, namely DOQAR (Dynamic Optimized QoE Adaptive Routing), to improve the user perception and optimize the usage of network resources. In our end-to-end model, smartphone users connect to content servers in a wired network across a wireless access network. In order to evaluate the QoE, we use a Multi-Layer Perception-based (MLP) method. Experimental results show a significant performance against other traditional routing protocols.
Connecting Medical Educational Resources to the Linked Data Cloud: the mEducator RDF Schema, Store and API

The existence of non-interoperable metadata schemas and limited use of shared vocabularies means that retrieving and processing educational resources across the Web represents a challenge. The emerging Linked Data paradigm has provided the tools and methods to share and expose metadata in a more unified and well interlinked manner, permitting both humans and machines to process Web data. The availability of vast amounts of RDF-based Linked Data is offering a worthwhile alternative to the isolated and heterogeneous data silos which previously dominated the Web. In the ECfunded project mEducator a standardised approach is proposed to describing and exposing medical educational resources. In this paper are described firstly the design considerations, and conceptual model upon which mEducator’s metadata scheme approach was based. Afterwards, follows the description of the serialization of the scheme in RDF/XML, and in turn follows an example showing how medical educational resources are exposed on the Web using an RDF endpoint, and discuss the potential advantages of this approach.
The Maya-Chortís Boundary: A Tectonostratigraphic Approach

This work presents an updated revision of the complex stratigraphic and tectonic relationships that characterize the geologic boundary between the Chortís and Maya continental blocks of the Caribbean region. Based on field, petrologic, structural and geochronological work in key areas of central Guatemala, as well as analysis of the relevant literature, we propose a new tectonostratigraphic structure that more fully appraises the fundamental tectonic role played by major faults that cut across the continental isthmus between the Americas, and bound separate tectonostratigraphic terranes (or fault blocks according to author JDK). Accordingly, we subdivide the area into seven of these units, from south to north: Chortís, Yoro, Sula, El Tambor, Jacalteco, Achí, and Maya, bounded respectively by the Agúan-La Ceiba, Jocotán-Chamelecón, Motagua, Baja Verapaz (defined in this work), and Chixoy-Polochic fault zones. Unfortunately, the extreme paucity of modern geologic data bearing on the pre-Cretaceous cover and basement units in the entire region constitutes a major obstacle for building convincing paleogeographic models to explain the complex tectonic evolution of the area from Precambrian to Cenozoic time. Consequently, this work should be taken as an attempt line to understand more clearly the nature and contact relationships between deep crustal blocks in nuclear Central America, and as a contribution to interpret their geologic evolution in plate tectonic terms.
Application Of Reinforcement Learning In Multisensor Fusion Problems With Conflicting Control Objectives

Abstract Smart agents are equipped with sensors that enable them to be sensitive to their surrounding environrnent. However, the mapping of multiple raw streams of sensory data to the appropriate actions is not an easy problem, especially when multiple conflicting objectives aze involved. This type of multi-sensor fusion problem through the domain of power management for smart mobile devices was investigated in this study. In this application domain, the objective is to keep the user’s mobile devices in an “on” state as long as possible such that just-in-time services (such as reminder announcements) can be provided. However, this conflicts with the mobile device’s inherent goal - to turn off to conserve power. Due to the stochastic nature of human behavior, ahand-coded fixed strategy may not be the best solution. A learning control approach to the problem is presented in this paper. The experimental results show that the approach learns the appropriate mapping from multiple streams of raw sensory data to.
Phylogeographical Analysis of Eremias argus in Yoobu-do Island and Sohwang Sand Dune, Korea

Abstract Eremias argus, which specifically inhabits riverside or coastal sand dune, is an endangered species designated by the Ministry of Environment of Korea because it has been drastically decreasing due to the destruction of habitat and the human activities. Therefore, it is required to prepare a countermeasure for the strategic and systematic solutions for the conservation of the E. argus. This study analyzed mtDNA cytochrome oxidase subunit I (COI) gene of E. argus inhabiting Yoobu-do island and Sohwang sand dune. This study aims to provide fundamental genetic information through phylogeographical analysis between two regions. Of 11 individuals of E. argus used in the analysis, the total 652∼656 bp of mtDNA COI genes for 3 individuals of Takydromus wolteri as ‘out group’ were analyzed. Intraspecific genetic distance for E. argus was shown to be the same result of 0.000. As for T. wolteri, it was 0.005, showing very similar result. T. wolteri inhabiting Gapcheon stream in Daejeon metropolitan city was found to be the highest intraspecific genetic distance (0.008). The NJ tree of E. argus and T. wolteri indicated there was almost no genetic difference between habitat for E. argus. For T. wolteri, however, there was slight difference between the individuals inhabiting Yoobu-do island and those inhabiting Gapcheon stream in Daejeon metropolitan city. Therefore, it is necessary to prepare conservation strategies to increase genetic diversity of E. argus in Yoobu-do island in the future because it is highly presumed that the population of E. argus in Yoobu-do island have been flown from nearby coastal sand dune.
Time-delay and Doppler-shift based geolocation in the presence of outliers

We address the problem of locating a stationary transmitter using receivers embedded in fast moving platforms. It is required to estimate the emitter location using time-delay and Doppler-shift measurements realized by the receivers at successive locations along their trajectories. Most publications consider small error measurements only, and overlook the possible presence of outliers in the set of time-delay and Doppler-shift measurements. In this work we discuss localization in the presence of outliers, where several measurements are severely corrupted while sufficient other measurements are reasonably precise. Following convexity and sparsity principles, we propose a localization algorithm with robustness against outliers.
In situ characterization of grain‐scale fluvial morphology using Terrestrial Laser Scanning

The grain‐scale morphology of fluvial sediments is an important control on the character and dynamics of river systems; however current understanding of its role is limited by the difficulties of robustly quantifying field surface morphology. Terrestrial Laser Scanning (TLS) offers a new methodology for the rapid acquisition of high‐resolution and high‐precision surface elevation data from in situ sediments. To date, most environmental and fluvial applications of TLS have focused on large‐scale systems, capturing macroscale morphologies. Application of this new technology at scales necessary to characterize the complexity of grain‐scale fluvial sediments therefore requires a robust assessment of the quality and sources of errors in close‐range TLS data. This paper describes both laboratory and field experiments designed to evaluate close‐range TLS for sedimentological applications and to develop protocols for data acquisition. In the former, controlled experiments comprising high‐resolution scans of white, grey and black planes and a sphere were used to quantify the magnitude and source of three‐dimensional (3D) point errors resulting from a combination of surface geometry, reflectivity effects and inherent instrument precision. Subsequently, a methodology for the collection and processing of grain‐scale TLS data is described through an application to a coarse grained gravel system, the River Feshie (D50 32 to 63 mm). This stepwise strategy incorporates averaging repeat scans and filtering scan artefact and non‐surface points using local 3D search algorithms. The sensitivity of the results to the filter parameter values are assessed by careful internal validation of Digital Terrain Models (DTMs) created from the resulting point cloud data. The transferability of this methodology is assessed through application to a second river, Bury Green Brook, dominated by finer gravel (D50 18 to 33 mm). The factor limiting the resolution of DTMs created from this second dataset was found to be the relative sizes of the laser footprint and smallest grains. Copyright © 2009 John Wiley & Sons, Ltd.
The Holsteinian Interglacial river network of mid‐eastern Poland and western Belarus

The Holsteinian drainage system in mid‐eastern Poland and western Belarus has been reconstructed using palaeogeographical analysis based on abundant boreholes. The stratigraphic setting and palaeogeography are determined by correlation with Holsteinian marine sediments in the Kaliningrad District of Russia and the Late Elsterian glaciolacustrine series in the southern peribaltic region. At the beginning of the Holsteinian there were numerous residual overflow lakes at the Polish‐Belarusian border area that gradually became interconnected with the Holsteinian Neman River and its tributaries. The base level of erosion is located in river beds of Holsteinian valleys slightly beneath beds of the recent rivers and indicates that Holsteinian sea level was apparently lower than the present Baltic Sea level. The Holsteinian Neman flowed southwestwards across the Biebrza River Basin to the Warsaw Basin. The main watershed between the Baltic Sea and the Black Sea was further to the west than its present location. The secondary watershed in northern Poland has only been slightly modified since that time.
Channel Selection in Multichannel Cognitive Radio Systems Employing RF Energy Harvesting

A decentralized channel access strategy is proposed for a multichannel low-power cognitive radio (CR) system. CRs are equipped with rechargeable batteries to harvest radio-frequency (RF) energy from the primary user (PU) transmission. At any time, secondary users (SUs) can exploit either the spatiotemporal spectrum opportunities for transmission or the PU active periods for RF energy harvesting. An optimal channel-selection probability vector is obtained to achieve the maximum SU throughput by finding sufficient spectrum-access and energy-harvesting opportunities while accounting for SU contention. We have a nonconvex optimization problem. It is decomposed to obtain a convex optimization subproblem, but an exhaustive search is required for the master problem. Alternatively, an iterative algorithm is proposed wherein we define a combined metric to consider the spectrum-access and energy-harvesting opportunities on different PU channels. A convex optimization problem is solved with a closed-form solution in each iteration. Numerical results show that the proposed channel-selection policy enables an SU to achieve better expected throughput through an enhanced battery-recharging probability.

What makes for good multiple object trackers?

This paper explores the importance of detection and appearance features for multiple object tracking. Extensive detectors including hand-crafted methods and deep learning methods have been tested. We found in this paper that simply improving detection performance can lead to much better multiple object tracking results. The data association methods used in this paper are Kalman Filter and Hungarian algorithm as proposed in [1]. CNN features and color histogram features are extracted as appearance features to measure similarities between objects. Our experiments show that appearance features can help with data association. We then combine detection and data association together as an overall system. The proposed system can track multiple objects at a speed of 17 fps with high accuracy.
Visualizing Multiple Fields on the Same Surface

A long-standing problem in the field of visualization is the ability to display many overlaid data sets. Researchers have developed successful techniques that show multiple 3D fields by layering sparse similar glyphs. My colleagues and I at the University of North Carolina have investigated this problem for a number of years. Our driving application has been the display of data sets from scanned-probe and scanned-electron microscopes, which led us to concentrate on the display of multiple scalar fields. Although several of our first approaches were initially successful, they failed to scale to more than three or four data sets. So that others will not be tempted to follow the same course, I begin by presenting the argument for, preliminary successes with, and reasons for the eventual downfall of our initial approach. I then describe the key concept that enables successful techniques.
Mass Classification Method in Mammogram Using Fuzzy K-Nearest Neighbour Equality

Mass classification of objects is an important area of research and application in a variety of fields. In this paper, we present an efficient computer aided mass classification method in digitized mammograms using Fuzzy K-Nearest Neighbor Equality, which performs benign or malignant classification on region of interest that contains mass. One of the major mammographic characteristics for mass classification is texture. Fuzzy K-Nearest Neighbor Equality exploits this important factor to classify the mass into benign or malignant. The statistical textural features used in characterizing the masses are Haralick and Run length features. The main aim of the method is to increase the effectiveness and efficiency of the classification process in an objective manner to reduce the numbers of false positive of malignancies. In this paper proposes a novel Fuzzy K-Nearest Neighbor Equality algorithm for classifying the marked regions into benign and malignant and 94.46 sensitivity,96.81 specificity and 96.52 accuracy is achieved that is very much promising compare to the radiologists' accuracy.
