A Privacy-aware Virtual Machine Migration Framework on Hybrid Clouds

With the proliferation of hybrid clouds in both cost-saving and effectiveness, a growing number of users are building their own private cloud. However, private cloud can only provide limited resource, and always resorts to public cloud in order to meet elastic service requirements. Generally, public cloud is operated by commercial service providers (CSPs) who are not completely honest with users to some extent. So, existing hybrid clouds service models are hampered by privacy concerns, and one of the main reasons is that a majority of users’ workloads involves sensitive contents and therefore can’t be directly outsourced to public cloud without proper protection. In this paper, we present a novel framework that makes such privacy-aware VM migration effectively. At First, all the users’ workloads are uploading and running in private cloud VMs then labeling the sensitive and non-sensitive VMs. Then, we design an effective way focusing on how to get VM migration queue without introducing heavy inter-cloud communication traffic after migration. Finally, non-sensitive VMs are migrated to public cloud with utmost effort by live migration premised on minimal service level agreement (SLA) disruption. Experiment results illustrate that our proposed framework is effective while occurring an acceptable communication overhead
Validation of the Middlesex Elderly Assessment of Mental State (MEAMS) as a cognitive screening test in patients with acquired brain injury in Turkey

Purpose. Assessment of cognitive impairment with a valid cognitive screening tool is essential in neurorehabilitation. The aim of this study was to test the reliability and validity of the Turkish-adapted version of the Middlesex Elderly Assessment of Mental State (MEAMS) among acquired brain injury patients in Turkey. Methods. Some 155 patients with acquired brain injury admitted for rehabilitation were assessed by the adapted version of MEAMS at admission and discharge. Reliability was tested by internal consistency, intra-class correlation coefficient (ICC) and person separation index; internal construct validity by Rasch analysis; external construct validity by associations with physical and cognitive disability (FIM); and responsiveness by Effect Size. Results. Reliability was found to be good with Cronbach's α of 0.82 at both admission and discharge; and likewise an ICC of 0.80. Person separation index was 0.813. Internal construct validity was good by fit of the data to the Rasch model (mean item fit −0.178; SD 1.019). Items were substantially free of differential item functioning. External construct validity was confirmed by expected associations with physical and cognitive disability. Effect size was 0.42 compared with 0.22 for cognitive FIM. Conclusion. The reliability and validity of the Turkish version of MEAMS as a cognitive impairment screening tool in acquired brain injury has been demonstrated.
Prediction and mediation of alcohol and drug abuse in criminals

substance use and criminals -2 Although there is considerable overlap between antisociality nd substance use problems, aparticularly among men, the basis of this connection is not well understood. Moreover, examination of the specific relationships, if any, between the constituent factors of psychopathy (i.e., emotional detachment and antisocial behavior) and substance use disorders is essentially uncharted. The study of incarcerated criminals, with their often significant alcohol and drug abuse histories, affords a unique opportunity to examine these relationships. In the present study, diagnostic, case file, and self-report data collected on 329 male prisoners included Short Michigan Alcohol Screening Test (SMAST) and Short Drug Abuse Screening Test (SDAST) indices of problem drinking and other drug abuse, respectively. These scores served as dependent variables in regression analyses of data from three other measures: The Psychopathy Checklist-Revised (PCL-R), the Alcohol Family Tree, the Drinking Motives Questionnaire (DRM), and the Multidimensional Personality Questionnaire (MPQ). Psychopathy evaluations yielded three PCL-R scores: a total and two factor scores. Factor 1, termed emotional detachment, represents callous, manipulative and selfish traits and a lack of remorse, empathy, and emotional depth. Factor 2, reflects simpler antisocial behavior, and includes impulsivity, sensation seeking, and early conduct problems. SPECIFIC AIMS 1. To replicate the general observation of a significant relationship between antisociality and substance use disorders, and then examine the more specific hypothesis (Smith & Newman, 1990) that
Myofilament Ca Sensitization Increases Cytosolic Ca Binding Affinity, Alters Intracellular Ca Homeostasis, and Causes Pause-Dependent Ca-Triggered Arrhythmia

Rationale: Ca binding to the troponin complex represents a major portion of cytosolic Ca buffering. Troponin mutations that increase myofilament Ca sensitivity are associated with familial hypertrophic cardiomyopathy and confer a high risk for sudden death. In mice, Ca sensitization causes ventricular arrhythmias, but the underlying mechanisms remain unclear. Objective: To test the hypothesis that myofilament Ca sensitization increases cytosolic Ca buffering and to determine the resulting arrhythmogenic changes in Ca homeostasis in the intact mouse heart. Methods and Results: Using cardiomyocytes isolated from mice expressing troponin T (TnT) mutants (TnT-I79N, TnT-F110I, TnT-R278C), we found that increasing myofilament Ca sensitivity produced a proportional increase in cytosolic Ca binding. The underlying cause was an increase in the cytosolic Ca binding affinity, whereas maximal Ca binding capacity was unchanged. The effect was sufficiently large to alter Ca handling in intact mouse hearts at physiological heart rates, resulting in increased end-diastolic [Ca] at fast pacing rates, and enhanced sarcoplasmic reticulum Ca content and release after pauses. Accordingly, action potential (AP) regulation was altered, with postpause action potential prolongation, afterdepolarizations, and triggered activity. Acute Ca sensitization with EMD 57033 mimicked the effects of Ca-sensitizing TnT mutants and produced pause-dependent ventricular ectopy and sustained ventricular tachycardia after acute myocardial infarction. Conclusions: Myofilament Ca sensitization increases cytosolic Ca binding affinity. A major proarrhythmic consequence is a pause-dependent potentiation of Ca release, action potential prolongation, and triggered activity. Increased cytosolic Ca binding represents a novel mechanism of pause-dependent arrhythmia that may be relevant for inherited and acquired cardiomyopathies.
Single-molecule analysis reveals self assembly and nanoscale segregation of two distinct cavin subcomplexes on caveolae

In mammalian cells three closely related cavin proteins cooperate with the scaffolding protein caveolin to form membrane invaginations known as caveolae. Here we have developed a novel single-molecule fluorescence approach to directly observe interactions and stoichiometries in protein complexes from cell extracts and from in vitro synthesized components. We show that up to 50 cavins associate on a caveola. However, rather than forming a single coat complex containing the three cavin family members, single-molecule analysis reveals an exquisite specificity of interactions between cavin1, cavin2 and cavin3. Changes in membrane tension can flatten the caveolae, causing the release of the cavin coat and its disassembly into separate cavin1-cavin2 and cavin1-cavin3 subcomplexes. Each of these subcomplexes contain 9 ± 2 cavin molecules and appear to be the building blocks of the caveolar coat. High resolution immunoelectron microscopy suggests a remarkable nanoscale organization of these separate subcomplexes, forming individual striations on the surface of caveolae.

Technical Debt Management in the Brazilian Federal Administration

Technical Debt (TD) is a metaphor to refer to events that bring quality loss in the code. A large volume of Technical Debt in an application may bring losses for the organisation that keeps it. For those organisations that outsource software development, monitoring TD in the influx of development packages may be an efficient strategy to ensure the quality of the product acquired. This works bring an account on the search for a TD management model, to allow a given Brazilian Federal Administration body to inspect how much debt an application has, as acquired in an outsourced way.
Second Opinion Expert Pathology Review in Bladder Cancer: Implications for Patient Care

Objectives. To review bladder specimens referred to our facility for secondary review to determine the frequency and degree of changes in pathological diagnoses, which could affect patient care. Methods. A retrospective review of 246 bladder specimens sent to our pathology department for second opinion pathological review was performed. All consultation specimens were reviewed by a single genitourinary (GU)-subspecialized surgical pathologist. Any changes in the pathological grade, stage, or histological tumor type were noted as well as patient demographic data. Statistical analysis was performed to determine the frequency and type of discrepancies in diagnoses and determine any associations with patient demographic parameters. Results. Secondary pathology consultation of 246 bladder specimens from 233 patients were reviewed and compared with the primary diagnosis. The diagnosis was altered in 91/246 cases (37.0%). The number of cases reviewed per patient and specimen type was not associated with a change in diagnosis (P = .19; P = .1). Of the cases with a change in diagnosis, 8 (8.8%) changed malignancy status, 46 (50.5%) changed stage, 16 (17.6%) changed tumor type (ie, change from urothelial carcinoma to prostate adenocarcinoma), 16 (17.6%) changed histological variant subtype, and 14 (15.4%) changed grade. There was no association noted between age, gender, or race and changes in diagnosis (P = .53; P = .41; P = .70). Conclusions. Secondary pathology review with a GU-subspecialized surgical pathologist can change the stage, grade, or histological subtype on bladder biopsy and tumor resection specimens in more than one-third of cases. Age and gender were not associated with the frequency of change in diagnosis on consultation review.
A Haptic Shared-Control Architecture for Guided Multi-Target Robotic Grasping

Although robotic telemanipulation has always been a key technology for the nuclear industry, little advancement has been seen over the last decades. Despite complex remote handling requirements, simple mechanically linked master–slave manipulators still dominate the field. Nonetheless, there is a pressing need for more effective robotic solutions able to significantly speed up the decommissioning of legacy radioactive waste. This paper describes a novel haptic shared-control approach for assisting a human operator in the sort and segregation of different objects in a cluttered and unknown environment. A three-dimensional scan of the scene is used to generate a set of potential grasp candidates on the objects at hand. These grasp candidates are then used to generate guiding haptic cues, which assist the operator in approaching and grasping the objects. The haptic feedback is designed to be smooth and continuous as the user switches from a grasp candidate to the next one, or from one object to another one, avoiding any discontinuity or abrupt changes. To validate our approach, we carried out two human–subject studies, enrolling 15 participants. We registered an average improvement of 20.8%, 20.1%, and 32.5% in terms of completion time, linear trajectory, and perceived effectiveness, respectively, between the proposed approach and standard teleoperation.
XML three-way merge as a reconciliation engine for mobile data

Optimistic replication approaches are often employed on mobile devices, which raises the need for reconciliation of concurrently modified data. We propose that three-way merging algorithms, in particular those that are able to process tree-structured data in XML format, make good candidates for a generic data reconciliation engine on mobile devices.By exchanging data through XML files we impose minimal constraints on application design and are able to offer reconciliation services to a large number of existing applications. Reconciliation support can be added to an application in several increments, allowing application developers to choose a suitable level of support compared to implementation effort. We give two examples of reconciliation by three-way merging of XML.
Parallel processing of spatial joins using R-trees

We show that spatial joins are very suitable to be processed on a parallel hardware platform. The parallel system is equipped with a so called shared virtual memory which is well suited for the design and implementation of parallel spatial join algorithms. We start with an algorithm that consists of three phases: task creation, task assignment and parallel task execution. In order to reduce CPU and I/O cost, the three phases are processed in a fashion that preserves spatial locality. Dynamic load balancing is achieved by splitting tasks into smaller ones and reassigning some of the smaller tasks to idle processors. In an experimental performance comparison, we identify the advantages and disadvantages of several variants of our algorithm. The most efficient one shows an almost optimal speed up under the assumption that the number of disks is sufficiently large.
Trends of Tree-Based,Set-Partitioning Compression Techniques in Still and Moving Image Systems

In addition to high compression efficiency, future still and moving image coding systems will require many other features. They include fidelity and resolution scalability, region of interest enhancement, random access decoding, resilience to errors due to channel noise or packet loss, fast encoding and/or decoding speed, and low computational and hardware complexity. Moreover, there are emerging new venues for the application of image compression techniques to data associated with points of a two or three-dimensional grid that will demand these features and perhaps others. We shall discuss these new venues along with the usual ones and show how tree-based, set-partitioning wavelet coding methods, such as SPIHT (Set Partitioning in Hierarchical Trees) and SPECK (Set Partitioning Embedded bloCK) will fulfill most of the demands of current and future applications. We shall also discuss the emerging JPEG-2000 in this framework.
Relationship of central incisor implant placement to the ridge configuration anterior to the nasopalatine canal in dentate and partially edentulous individuals: a comparative study

Background. The aims of this study were to investigate the ridge contour anterior to the nasopalatine canal, and the difference between the incidences of the nasopalatine canal perforation in dentate and partially edentulous patients by cone-beam computed tomography. Methods. Cone-beam computed tomography scan images from 72 patients were selected from database and divided into dentate and partially edentulous groups. The configuration of the ridge anterior to the canal including palatal concavity depth, palatal concavity height, palatal concavity angle, bone height coronal to the incisive foramen, and bone width anterior to the canal was measured. A virtual implant placement procedure was used, and the incidences of perforation were evaluated after implant placement in the cingulum position with the long axis along with the designed crown. Results. Comparing with variable values from dentate patients, the palatal concavity depth and angle were greater by 0.9 mm and 4°, and bone height was shorter by 1.1 mm in partially edentulous patients, respectively. Bone width in edentulous patients was narrower than in dentate patients by 1.2 mm at incisive foramen level and 0.9 mm at 8 mm subcrestal level, respectively. After 72 virtual cylindrical implants (4.1 × 12 mm) were placed, a total of 12 sites (16.7%) showed a perforation and three-fourths occurred in partially edentulous patients. After replacing with 72 tapered implants (4.3 × 13 mm), only 6 implants (8.3%) broke into the canal in the partially edentulous patient group. Conclusions. The nasopalatine canal may get close to the implant site and the bone width anterior to the canal decreases after the central incisor extraction. The incidence of nasopalatine canal perforation may occur more commonly during delayed implant placement in central incisor missing patients.
Effects of Perceived Costs and Rewards on Motivation and Retention of Rape Crisis Center Volunteers

The purpose of this study was to obtain information that may assist Rape Crisis Center (RCC) volunteer coordinators and executive directors in the recruitment and retention of volunteers. The major hypotheses guiding this study are as follows: (a) the reasons that initially motivated volunteers to volunteer at the RCC will be the same as their reasons for why they are continuing to volunteer at the RCC and (b) volunteers at RCCs continue to volunteer because the perceived costs of volunteering do not exceed the perceived rewards of volunteering. Using a modified version of Black's (1989) questionnaire, respondents were asked to report on several aspects of their volunteer experience such as (a) reasons for volunteering and reasons for remaining a volunteer; (b) the importance of acceptance by other volunteers, staff, and clients; (c) level of satisfaction with their volunteer experience; (d) perceived costs and rewards of volunteering; and (e) demographic characteristics. In support of the first hypothesis, "to help persons in need" had the highest mean score for both the motivations for volunteering and the motivations for continuing to volunteer. Twelve out of the fourteen reasons that initially motivated volunteers to volunteer at the RCC were the same reasons for why they continue to volunteer at the RCC. Contrary to expectations of the second
Supramolecular structure of a new family of circular proteoglycans mediating cell adhesion in sponges.

Aggregationfactors are the molecules responsible for species-specific cell adhesion in sponges. Here, we present the structure of the aggregation factor from the marine sponge Microciona prolifera, which constitutes the first description of a circular proteoglycan. We have analyzed chemically dissociated and enzymatically digested aggregation factor with atomic force microscopy, agarose gel electrophoresis, and Western blots using antibodies against the protein and carbohydrate moieties. Twenty units from each of two N-glycosylated proteins, MAFp3 and MAFp4, form the central ring and radiating arms, respectively, stabilized by a hyaluronidase-sensitive component. MAFp3 carries a 200-kDa glycan involved in homologous self-interactions between aggregation factor molecules, whereas MAFp4 carries a 6-kDa glycan that binds cell surface receptors. A 68-kDa lectin found in cell membranes of several sponge species binds the aggregation factor and its protein-free glycans, as well as chondroitin sulfate and hyaluronan. Here, we show that despite their lack of clear sequence homologies with other known proteoglycan structures, the protein and carbohydrate components of sponge aggregation factors assemble to form a supramolecular complex remarkably similar to classical proteoglycans.
Transcriptional Analysis of the Principal Cell Division Gene, ftsZ, of Mycobacterium tuberculosis

ABSTRACT Multiple promoters drive the expression of the principal cell division gene, ftsZ, in bacterial systems. Primer extension analysis of total RNA from Mycobacterium tuberculosis and a Mycobacterium smegmatis transformant containing 1.117 kb of the upstream region of M. tuberculosis ftsZ and promoter fusion studies identified six ftsZ transcripts and their promoters in the ftsQ open reading frame and ftsQ-ftsZ intergenic region. The presence of multiple promoters reflects the requirement to maintain a high basal level of, or to differentially regulate, FtsZ expression during different growth conditions of the pathogen in vivo.
Static and dynamic properties of hexagonally shaped magnetic nanotubes

In the framework of this thesis the magnetic ground state of hexagonally shaped ferromagnetic nanotubes and ways to manipulate this state are investigated in detail. The nanotubes consist of permalloy with possible additional layers such as aluminum oxide. Utilizing the anisotropic magnetoresistance effect (AMR) we find very stable vortex ground states that are independent of the geometry of the nanotube. The reason is attributed to a strong growth induced anisotropy which is quantified in the course of this thesis. Besides the statics, also the dynamics of the magnetic nanotubes is investigated. For this purpose, three different techniques are applied: Planar microresonator based ferromagnetic resonance (PMR based FMR), time resolved magneto optical Kerr effect (TRMOKE) spectroscopy and scanning transmission X-ray microscopy (STXM). We find a highly asymmetric spin wave dispersion both experimentally and within the conducted simulations. These findings mark the first experimental evidence of the non-reciprocity of spin waves, caused solely by the curvature of the magnetic nanotubes.
Removal of Radiometric Degradation Using Blur Invariants in Wavelet Domain

—Radiometric degradation and geometric distortion is a general problem in the image restoration considering many applications. The goal of image restoration is to create complete description of the original image from a degraded observation. The degradation may include blur, losses of information due to testing, quantization effects and different source of noise, camera misfocus, and atmospheric turbulence. There are many researches going about effort to deblur such image. To manage this problem various blur invariants to exist. The wavelet domains blur invariants that are centrally symmetric to blur. Blur invariants are constructed from different wavelet function. In this paper, image registration is done by using blur invariants. Template image is chosen in the degraded images using similarity the template image is matched with the original image. Even in the severely degraded images the images are accurately registered using Daubuchies wavelet functions, compared to the spatial domain blur invariants which may result in misfocus registration of an image. The proposed method, image restoration is above using Daubechies and B-Spline Wavelet function. Then a regression based process is going about to produce an image convolved with near diffraction limited PSF, which can be shown as blur invariant. Eventually, a blind deconvolution algorithm carried out to remove diffraction limited blur from the linear image to create the final output. It is used in many different fields of application such as photography deblurring, remote sensing, medical imaging, and forensic science.
