Surgical Management of Infected Radicular Cyst using PRF and Graft Augmentation

The radicular cyst is one of the most commonly occurring cysts in the oral cavity. It is usually preceded by trauma or an infection which is followed by enlargement. In recent times there are several treatment procedures that are being applied to improve the postoperative condition and to accelerate the process of healing and regeneration in the affected site. A 30year-old patient reported to our OPD with the chief complaint of swelling on the left side of the face since 2-3 months, on investigation a diagnosis of radicular cyst was given, which was initially treated by endodontic treatment of the involved tooth followed by enucleation of the cyst and apicoectomy. PRF and G bone grafthydroxyapatite crystals were placed for aesthetic rehabilitation with 21.
Scale invariant and fixed-length feature extraction by integrating discrete cosine transform and autoregressive signal modeling for palmprint identification

Recently, the need for automatic identification has caused researchers to focus on biometric identification methods. Palmprint-based biometric identification has several advantages such as user friendliness, low-cost capturing devices, and robustness. In this paper, a method that integrates the discrete cosine transform (DCT) and an autoregressive (AR) signal modeling is proposed for biometric identification. The method provides scale invariance and produces a fixed-length feature vector. In particular, the Burg algorithm is used for the determination of the AR parameters used as a feature vector. Experimental results demonstrate that a small number of the AR parameters that are modeling the DCT coefficients of a palmprint are sufficient to constitute a practically applicable identification system achieving a correct recognition rate of 99.79%. The accuracy of the proposed approach is not overly dependent on the number of training samples, another advantage of the method.

A simple approach to modeling cross-talk in integrated circuits

A simple engineering approach for rapid simulation of crosstalk in mixed-mode ICs using SPICE is presented. Comparative two-dimensional simulations of test structures incorporating different isolation schemes are presented. Lumped parameter equivalent circuits are then developed for these test structures for use in SPICE. The small-signal characteristics of the test structures are computed using SPICE and the results compared with those obtained from two-dimensional device simulation. Results are also compared with experimental measurements to validate the models.
SUPPORTING MULTIPLE ISOLATION LEVELS IN REPLICATED ENVIRONMENTS.

Replication is used by databases to implement reliability and provide scalability. However, achieving transparent replication is not an easy task. A replicated database is transparent if it can seamlessly replace a standard stand-alone database without requiring any changes to the components of the system. Database replication transparency can be achieved if: (a) replication protocols remain hidden for all other components of the system; and (b) the functionality of a stand-alone database is provided. The ability to simultaneously execute transactions under different isolation levels is a functionality offered by all stand-alone databases but not by their replicated counterparts. Allowing different isolation levels may improve overall system performance. For example, the TPC-C benchmark specification tolerates execution of some transactions at weaker isolation levels in order to increase throughput of committed transactions. In this Ph.D. Thesis we identify the conditions under which replication protocols may manage multiple isolation levels transparently and prove that protocols that satisfy these conditions are correct [3]. To this end, we suggest a new Snapshot Isolation level definition which fits better with the dependency graphs used as a base representation of transaction conflicts [1]. This definition unifies the base SI definition and the generalised version [2] suggested in other works [1, 4]. We also modify the popular ROWAA-based replication scheme to support different isolation levels. As an example, we demonstrate how these extensions can be applied to specific protocols. The majority of the replication solutions under consideration require only minor changes to support multiple isolation levels, which may result in an improved degree of concurrency and minor transaction completion times for those transactions that can be executed in a relaxed isolation level. Our model is general enough to be applied to any database replication protocol. [1] A. Adya. Weak Consistency: A Generalized Theory and Optimistic Imple- mentations for Distributed Transactions.

An approach to automatically segment the media-adventitia borders in

By being able to show morphological and pathological aspects of atherosclerosis, the Intravascular Ultrasound (IVUS) became one of the most reliable and employed medical imaging modality in cardiac interventions. Its image characteristics increase the chances of a good diagnostic, resulting in a precise therapy. The study of media-adventitia borders segmentation in IVUS, among many applications, is important for learning about the mechanical properties and determining some specific measurements (radius, diameter, etc.) in vases and plaques. An approach is proposed to achieve high accuracy in media-adventitia borders segmentation, by making a combination of different image processing operations: Speckle Reducing Anisotropic Diffusion (SRAD), Wavelet, Otsu and Mathematical Morphology. Firstly, SRAD is applied to attenuate the speckle noise. Next, the vessel and plaque features are extracted by performing Wavelet Transform. Optimal thresholding is carried out by Otsu method to create a binarized version of these features. Then, Mathematical Morphology operations are used to obtain an adventitia shape. The proposed approach is evalu ated by segmenting 100 challenging images, obtaining an avera ge of True Positive (TP(%)) = 92.83 ± 4.91, False Positive (FP(%)) = 3.43 ± 3.47, False Negative (FN(%)) = 7.17 ± 4.91, Max False Positive (Max FP (mm)) = 0.27 ± 0.22, Max False Negative (Max FN (mm)) = 0.31 ± 0.2. The effectiveness of our approach is demonstrated by comparing this result with another recent work in the literature.
Correspondence: Nerve–muscle specificity

A correspondence item entitled ‘A warning against revival of the classic tenets of gross anatomy related to nerve–muscle specificity’ was recently published in the Journal of Anatomy (Shinohara, 1996a). The present correspondent fully agrees with some aspects of his opinion, in particular, the 3 laws about applications which he described, and he also appreciates his approach to the argument based on the results of embryology and experimentation. However, his denial of morphological interpretations based on the theory of nerve–muscle specificity may be due to an incomplete understanding of the current status of the theory.
AOP: An R Package For Sufficient Causal Analysis in Pathway-based Screening of Drugs and Chemicals for Adversity

Summary How can I quickly find the key events in a pathway that I need to monitor to predict that a/an beneficial/adverse event/outcome will occur? This is a key question when using signaling pathways for drug/chemical screening in pharmacology, toxicology and risk assessment. By identifying these sufficient causal key events, we have fewer events to monitor for a pathway, thereby decreasing assay costs and time, while maximizing the value of the information. I have developed the “aop” package which uses back-door analysis of causal networks to identify these minimal sets of key events that are sufficient for making causal predictions. Availability and Implementation The source for the aop package is available online at Github at https://github.com/DataSciBurgoon/aop and can be installed using the R devtools package. The aop package runs within the R statistical environment. The package has functions that can take pathways (as directed graphs) formatted as a Cytoscape JSON file as input, or pathways can be represented as directed graphs using the R/Bioconductor “graph” package. The “aop” package has functions that can perform backdoor analysis to identify the minimal set of key events for making causal predictions. Contact lyle.d. burgoon@usace.army. mil
A Glowworm Optimization Method for the Design of Web Services

A method for adaptive usability evaluation of B2C eCommerce web services is proposed. For measuring eCommerce usability a checklist integrating eCommerce quality and usability is developed. By a Glowworm swarm optimization (GSO) neural networks-based model the usability dimensions and their checklist items are adaptively selected. A case study for usability evaluation of an eCommerce anthurium retail website is carried out. The experimental results show that GSO with neural networks supports the allocation of usability problems and the defining of relevant improvement measures. The main advantage of the approach is the adaptive selection of most significant checklist dimensions and items and thus significant reduction of the time for usability evaluation and design.
Cue Integration for Manipulation

Robustness of vision is a notorious problem in vision, and it is one of the major bottlenecks for industrial exploitation of vision. One hypothesis is that fusion of multiple natural features facilitates robust detection and tracking of objects in scenes of realistic complexity. Use of dedicated models of objects of interest is another approach to the robustness problem. To provide some generality the use of natural features for estimation of the end-effector position is pursued in this work. The research investigates two different approaches to cues integration, one based on voting and another based on fuzzy logic. The two approaches have been tested in association with scenes of varying complexity. Experimental results clearly demonstrate that fusion of cues results in added robustness and increased estimation performance. The robustness is in particular evident for scenes with multiple moving objects and partial occlusion of the object of the interest.
Severe Acute Malnutrition (SAM) Evaluation of Associated Risk Factors, Screening Tools, and Therapeutic Management among South Sudanese Children Age 6

Severe Acute Malnutrition (SAM) is a major silent killer among children under five years of age, in low resources settings. It’s also being regarded as a disease of hungry communities. Therefore, to assess and classify an individual nutritional status under SAM is by anthropometry that determines body measurement. Measurable variables, age, sex, weight, height and Mid-Upper Arm-Circumference (MUAC) for children 6-59 months. SAM characterized with visible wasting and bilateral edema, in infants <6 months. However, social criteria like the absence of a mother or inadequacy of breastfeeding predict nutritional risk. Once more, SAM in U5 assessed by nutritional indices of Weight-For-Height (WFH), MUAC, and bilateral edema. Children 5-19 years BMI-for-age plus clinical signs are used. MUAC preferable during pregnancy. WHO Growth Standards of 2007 suggested over NCHS 1978. Nutrition indices in Z-scores opposed to median percentage. Median off use in classifying individual’s nutritional status. Methods and protocols for assessment of children 6-59 months are more developed than for other age. Therefore, best practice to produce functional outcomes is needed. The level of malnutrition at admission phase influences hospitals stay. Evidence suggests that malnutrition is more frequent and severe among males than females. Implications, no special consideration in severe acute malnutrition admitted in a critical phase”. Protocols to discharge patients upon recovery needs harmonization. MUAC misdiagnose Kwashiorkor children due to fluid retention but remains a reliable tool. Ready to Use Therapeutic Food (RUTF) used for management of SAM. The study aimed to evaluate the effectiveness of screening tools, therapeutic interventions and shed light on the risk factors associated with SAM. A later effect includes but not limited to mental retardation, poor school performance, and low self-esteem.
Use of selected methods of measurement in the assessment of milkers’ workload in the traditional milking

The activities connected with the milker’s work are directly related to maintaining a special body posture due to the tension of specific muscles. Staying in one required position for a long time and work monotony in case have a negative effect on the person’s musculoskeletal system. Therefore a study was conducted to evaluate the level of muscle tension and perceptible load while performing individual steps of hand-milking procedure. A detailed timing of the milker’s work was also recorded. The workload was assessed according to the OWAS method and muscle tension was assessed according to the EMG method. On the basis of collected data it was assumed that the highest muscle tension for the evaluated group of 10 milkers was achieved with the forearm muscles. It is strictly connected with hands being raised forward and repeating the same movements. Based on the OWAS method it was observed that the milker’s overall workload level can be described as medium. Farmers conducting milking should have adequate work breaks and should reduce workload on the musculoskeletal system whenever possible.

An Improved LEACH Multi-hop Routing Protocol Based on Genetic Algorithms for Heterogeneous Wireless Sensor Networks

In this paper, we propose a multi-hop routing algorithm LEACH-GA (LEACH-Genetic Algorithm) to improve the cluster heads single-hop system in the LEACH routing protocol of heterogeneous wireless sensor network. In this protocol, the cluster heads provide a shortest path link with SINK. The cluster heads who are far away from SINK communicate with SINK through the transit cluster heads. While, in fact, those who are near SINK can communicate with it directly. From this point, the LEACH algorithm can be improved to be an algorithm with SINK-centered multi-hop tree cluster link. Simulation of LEACH algorithm and LEACH-GA indicate that, compared with LEACH algorithm, LEACH-GA reduces the energy consumption of the cluster heads and prolongs the lifetime of the network.
Modelling the Errors in Areal Interpolation between Zonal Systems by Monte Carlo Simulation

Areal interpolation involves the transfer of data (often socioeconomic statistics and especially population data) from one zonation of a region to another, where the two zonations are geographically incompatible. This process is inevitably imprecise and is subject to a number of possible errors depending on the assumptions inherent in the methods used. Previous analysts have had only limited information with which to compare the results of interpolation and so assess the errors. In this paper a Monte Carlo simulation method based on modifiable areal units is employed. This allows multiple interpolations of population to be conducted from a single set of source zones to numerous sets of target zones. The properties of the full error distribution associated with a particular interpolation model can then be examined. The method based on dasymetric mapping consistently gave the highest accuracy of those tested, whereas the areal weighting method gave the lowest. More important than the results presented is the potential for future testing of other methods in increasingly complex situations.
Prevalence and molecular characterization of fluoroquinolone resistance in Escherichia coli isolates from dairy cattle with endometritis in China.

Fluoroquinolones are frequently used to treat infectious disease that is caused by Escherichia coli in dairy cattle. However, fluoroquinolone resistance occurs and is due either to chromosomal mutations in the bacterial topoisomerase genes and/or to plasmid-mediated resistance genes. The purpose of this study was to determine the prevalence and molecular characteristics of fluoroquinolone resistance determinants in E. coli strains (n=148) isolated from dairy cattle with bovine endometritis in Inner Mongolia (China). Analysis of the mutations in the quinolone resistance-determining regions of resistant E. coli isolates confirmed previously reported substitutions in the GyrA and ParE. However, we identified additional substitutions in the ParC and GyrB that have not been reported earlier. No plasmid-mediated quinolone resistance genes in any of the isolates were found. The number of point mutations found per isolate correlated with an increase in the minimum inhibitory concentration of ciprofloxacin. Overal.

This work describes a protocol that provides a practical solution for the problem of cryptographic key establishment and secure communication in the context of Wireless Sensor Networks, in which computational efficiency is a fundamental requirement. Such protocol was implemented in the EPOS operating system and takes the form of a network layer that provides the principles of data integrity, authenticity and confidentiality. Tests were executed on the EPOSMoteII platform and the analysis of the results shows that the implementation is adequate to be used in the scenario of embedded systems with low proccessing power.
Multiple meanings and modes: on the many ways to be a generalist flower

The concept of a generalist flower appears to mean different things to different people, depending upon their background and training. We assess the different meanings of generalist flowers with respect to the ecological "set and setting" of pollination, and then we discuss notions of ecological, functional and phenotypic generalization. These ideas are explored in more detail using examples from our own published and unpublished studies on the pollination ecology of Daucus carota, Hedera helix, and Chamerion angustifolium, and from the published work of other researchers. Finally we relate these ideas and clarified definitions of "generalist" and "specialist" flowers to the pollination syndrome concept.
Improvement of Finger Vein Verification by Blocked Filtering Method

We manufactured compact personal verification device using finger veins. We already have developed a personal verification device. Doing verification experiments on a new device using the conventional verification method, the result of verification rate was 99.5(%). Therefore, we find problems of conventional verification method and propos new method. Specifically, we propose a method emphasizes edge of finger on the purpose of improving the accuracy of lean correction and method of emphasizing the vein with higher accuracy. Verification rate on the verification experiments increased to 99.9% by incorporating two methods.
The Effect of Acknowledgment Traffic on the Capacity of Packet-Switched Radio Channels

We consider a population of terminals communicating with each other or with a central station over a packet-switched multiple access radio channel. To ensure the integrity of the transmitted data over the multi-access channel, we consider a reliable method using an error detecting block code in conjunction with a positive acknowledgment of each correct message. In this paper, we study the effect on channel capacity of the overhead created by the error-control traffic for both slotted ALOHA [1] and carrier sense multiple access (CSMA) [2]. For this we consider several implementation schemes for the two channel configurations: the common-channel configuration (a single channel for both information traffic and error-control traffic); and the split-channel configuration. The packet delay analysis will be treated in a forthcoming companion paper.
Expression of transforming growth factor β type II receptor leads to reduced malignancy in human breast cancer MCF-7 cells

Abstract The role of transforming growth factor (TGF) beta type II receptor in reversing the malignant phenotype of human breast cancer MCF-7 cells was examined. MCF-7 cells were insensitive to TGF beta 1 and expressed undetectable levels of cell surface TGF beta type I receptor (RI) and type II receptor (RII) by cross-linking with 125I-TGF beta 1. Stable transfection of a RII expression vector yielded 3 transfectants with varying levels of exogenous RII mRNA and protein levels. Expression of RII also increased TGF beta 1 binding to RI in all 3 clones. Proliferation of RII-positive clones was inhibited by exogenous TGF beta 1 in a dose-dependent manner, whereas the control clones remained TGF beta-insensitive. The RII transfectants were growth arrested in monolayer culture at saturation densities which were 41-66% of that of the Neo controls. They also showed reduced clonogenicity in soft-agarose. Tumorigenicity in ovariectomized, estrogen-supplemented nude mice was delayed in transfectants with low RII levels. Transfectants expressing high levels of RII showed a large reduction in tumorigenicity as well as a longer delay in tumor formation. Tumor growth was associated with loss of exogenous RII expression in transfectants. The results indicate that when systems for TGF beta signal transduction are intact, reconstitution of the TGF beta receptor system can lead to reversion of malignancy in cells lacking RII.
