Verifiable Mechanism for Attribute Based Encryption in Cloud Computing

Cloud computing technology brings innovative computing facilities to the management of the data resources. In the computing environments, the cloud servers can offer various data services such as remote data storage, outsourced delegation, computing applications. sharing and retrieving the data are ensure with Ciphertext PolicyAttribute Based Encryption (CPABE), Verifiable Delegation (VD) which helps in data isolation and the verifiability of entrustment on fraudulent cloud serve rs. In the cloud, for achieve access control and trust data top secret, the data owners could take up attribute-based encryption to encrypt the stored data. During the encryption process the access policies may not be flexible enough. The proposed secure outsourced ABE technique addresses on key issuing and Attribute-based encryption (ABE) with outsourced decryption not only enables finegrained sharing of encrypted data, but also overcomes the efficiency drawback (in terms of ciphertext size and decryption cost) of the standard ABE schemes. In particular, an ABE scheme with outsourced decryption allows a third party (e.g., a cloud server) to transform an ABE ciphertext into a (short) ElGamal-type ciphertext using a public transformation key provided by a user so that the latter can be decrypted much more efficiently than the former by the user.
Prolonged Expression of Secreted Enzymes in Dogs After Liver-Directed Delivery of Sleeping Beauty Transposons: Implications for Non-Viral Gene Therapy of Systemic Disease.

The non-viral, integrating Sleeping Beauty (SB) transposon system is efficient in treating systemic monogenic disease in mice, including hemophilia A and B caused by deficiency of blood clotting factors and mucopolysaccharidosis types I and VII caused by α-L-iduronidase (IDUA) and β-glucuronidase (GUSB) deficiency, respectively. Modified approaches of the hydrodynamics-based procedure to deliver transposons to the liver in dogs were recently reported. Using the transgenic canine reporter secreted alkaline phosphatase (cSEAP), transgenic protein in the plasma was demonstrated for up to 6 weeks post infusion. This study reports that immunosuppression of dogs with gadolinium chloride (GdCl3) prolonged the presence of cSEAP in the circulation up to 5.5 months after a single vector infusion. Transgene expression declined gradually but appeared to stabilize after about 2 months at approximately fourfold baseline level. Durability of transgenic protein expression in the plasma was inversely associated with transient increase of liver enzymes alanine transaminase and aspartate transaminase in response to the plasmid delivery procedure, which suggests a deleterious effect of hepatocellular toxicity on transgene expression. GdCl3 treatment was ineffective for repeat vector infusions. In parallel studies, dogs were infused with potentially therapeutic transposons. Activities of transgenic IDUA and GUSB in plasma peaked at 50-350% of wildtype, but in the absence of immunosuppression lasted only a few days. Transposition was detectable by excision assay only when the most efficient transposase, SB100X, was used. Dogs infused with transposons encoding canine clotting factor IX (cFIX) were treated with GdCl3 and showed expression profiles similar to those in cSEAP-infused dogs, with expression peaking at 40% wt (2 μg/mL). It is concluded that GdCl3 can support extended transgene expression after hydrodynamic introduction of SB transposons in dogs, but that alternative regimens will be required to achieve therapeutic levels of transgene products.
Fading and scattering due to trees in L to Ka band propagation simulations

Vegetation effects on electromagnetic wave propagation can have a strong impact on many localization or communication systems. This situation explains an increasing interest in the development of tree attenuation and scattering models which could help in the characterization of complex propagation environments. In this paper, we propose a general methodology to compute propagation effects due to a set of trees based on a point scattering model and the multiple scattering theory. We show its capacity to generate realistic simulations in good accordance with S band measurements.
Numerical Modelling and Simulation of Sand Dune Formation in an Incompressible OutFlow

In this paper, we are concerned with computation of a mathematical model of sand dune formation in a water of surface to incompressible out-flows in two space dimensions by using Chebyshev projection scheme. The mathematical model is formulate by coupling Navier-Stokes equations for the incompressible out-flows in 2D fluid domain and Prigozhin’s equation which describes the dynamic of sand dune in strong parameterized domain in such a way which is a subset of the fluid domain. In order to verify consistency of our approach, a relevant test problem is considered which will be compared with the numerical results given by our method.
Chewing lice (Phthiraptera: Amblycera et Ischnocera) from wrens (Passeriformes: Troglodytidae), with description of a new species of Myrsidea

A total of 114 individuals of 14 wren species (Aves: Passeriformes: Troglodytidae) were examined. Nineteen birds (17 %) of six species were parasitised with 292 chewing lice (mean intensity = 15.4 lice per bird) belonging to three genera – Brueelia Keler, 1936, Penenirmus Clay & Meinertzhagen, 1938 (Ischnocera: Philopteridae) and Myrsidea Waterston, 1915 (Amblycera: Menoponidae). Data on the occurrence of chewing lice on wrens, including geographical distributions and some parasitological parameters – such as prevalence and mean intensity – are updated and discussed. A description and illustrations are given for Myrsidea fasciata sp. nov. from Campylorhynchus fasciatus (Swainson, 1837) from Costa Rica. Penenirmus albiventris (Scopoli, 1763) is redescribed from Troglodytes troglodytes (Linnaeus, 1758) (from the Czech Republic and Slovakia) and from T. aedon Vieillot, 1809 (from Peru). Intraspecific morphological variation of P. albiventris is discussed, and detailed figures are given. A portion of the mitochondrial cytochrome oxidase I (COI) gene was sequenced from some species of Myrsidea and Penenirmus in order to assess their relative genetic divergence. An updated list of all species of lice recorded from wrens, including their geographic distribution, and a host-louse list are also given.
Factors Affecting English Vocabulary Skill of Undergraduates

This study aimed to examine factors affecting the English vocabulary recognition of undergraduate students in Thailand. The sampled subjects comprised 785 undergraduates from 6 faculties enrolled in the second semester of the 2005 academic year at Prince of Songkla University, Pattani Campus. The data were collected using a questionnaire based on 10 common English words, each of which the respondents were asked to match to one of five similar words including four distracters and one correct synonym. Respondents were also invited without coercion to give their student registration number, enabling demographic and enrolment details to be matched to their answers. Over 97% of those surveyed gave their number, and took 5 minutes on average to complete the test, giving a mean score of 5.4 correct answers (standard deviation 2.5). Multiple regression analysis of the results showed that the students’ scores were related to their level of seniority, faculty of enrolment, and major field of study, but bore no relation to their gender, religion, or type of high school attended. The students who performed by far the best were a group of 113 majoring in Language (English, French, Malayu, Arabic or Thai) in the Faculty of Humanities. Students who had obtained an A or B grade in a compulsory one-semester English unit also did better on the test. Although the test requires further extensive evaluation with respect to its internal and external validity, compared to alternatives it has the advantage of simplicity and ease of administration.
CLONING OF POLY (3-HYDROXYBUTYRATE) SYNTHESIS GENES FROM AZOTOBACTER VINELANDII INTO ESCHERICHIA COLI

The Azotobacter vinelandii is an aerobic, nitrogen-fixing bacterium with the ability to accumulate polyesters such as poly (3-hydroxybutyrate), a particular group of the polyhydroxyalkanoates (pha), when will be cultivated on several carbon sources, including sucrose. Although the capacity of Azotobacter strains to accumulate polyesters is well known, and the genes responsible for their synthesis have recently been identified. However, high production costs have hindered the use of polyhydroxyalkanoates as bioplastics, since their final price is considerably high. The phb gene clusters including phbBAC genes can alternatively be cloned and expressed in the Escherichia coli with the goal to produce high cell density cultivation. We amplified separately the phbB, phbA and phbC genes from extracted Azotobacter genome with the designed primers and could clone the fragments in the cloning vector pCR 2.1- TOPO with the subsequent transformation of E. coli strain DH5α.
Dopamine Agonist Modifies Cortical Activity in Parkinson Disease: A Functional Neuroimaging Study

ObjectivesTo investigate, using functional magnetic resonance imaging, the influence of a long-term dopaminergic therapy on brain activation during a simple motor task in early, previously untreated patients with Parkinson disease. MethodsThirteen patients with Parkinson disease in Hoehn-Yahr stage 1 or 2, with a right predominance of the disease, underwent functional magnetic resonance imaging during self-paced continuous right-hand tapping before and after 6 months of therapy with ropinirole 15 mg/d. The task was monitored online with a dedicated device, which measures the strength and frequency of the tapping. ResultsAll patients with Parkinson disease on ropinirole treatment showed a clinically significant improvement, and their functional magnetic resonance imaging pattern after treatment showed a reduced activation in the right postcentral (primary sensory-motor area), supramarginal and inferior parietal gyri compared with the activation pattern before treatment. No area of increased activation was observed after therapy. ConclusionsIn line with the classical functional deafferentation hypothesis, dopaminergic stimulation should increase motor cortex activity as a result of restoration of the striatocortical loops. On the contrary, our results challenge this hypothesis as we found decreased cerebral activity after a short-term chronic dopaminergic treatment. We suggest that the recruitment of cortical motor circuits aimed to overcome the functional deficit of the striatocortical loops lessens after dopaminergic treatment.
Immunopathological effects of malaria pigment or hemozoin and other crystals

Blood‐stage malaria parasites produce insoluble hemozoin (Hz) crystals that are released in the blood circulation upon schizont rupture. In general, endogenous crystal formation or inhalation of crystalline materials is often associated with pathology. As the immune system responds differently to crystalline particles than to soluble molecules, in this review, the properties, immunological recognition, and pathogenic responses of Hz are discussed, and compared with two other major pathogenic crystals, monosodium urate (MSU) and asbestos. Because of the size and shape of MSU crystals and asbestos fibers, phagolysosomal formation is inefficient and often results in leakage of lysosomal content in the cell cytoplasm and/or in the extracellular environment with subsequent cell damage and cell death. Phagolysosomal formation after Hz ingestion is normal, but Hz remains stored inside these cells for months or even longer without any detectable degradation. Nonetheless, the different types of crystals are recognized by similar immune receptors, involving Toll‐like receptors, the inflammasome, antibodies, and/or complement factors, and through similar signaling cascades, they activate both proinflammatory and anti‐inflammatory immune responses that contribute to inflammation‐associated pathology.

Cloning and Characterization of 5′-Upstream Sequence of the M32 Gene for a Mouse Homologue of Drosophila Heterochromatin Protein 1 (HP1)

M32 [also termed chromatin modifier protein 2 (MOD2)] is a nuclear protein consisting of the condensed chromatin structure (heterochromatin) and considered one of the mammalian homologues of heterochromatin protein 1 (HP1), first isolated as one of the components of heterochromatin in Drosophila. This report presents the isolation and characterization of the 5′-upstream region of the mouse M32 gene containing a promoter region and 5′-untranslated region (5′-UTR) exon. The 5′-upstream region (approximately 0.27 kb starting from the 5′ end of the 5′-UTR exon) of the M32 gene contained neither a TATA box nor a CCAAT box, but possessed potential binding sites for transcription factors such as Spl, H4TF-1, PEA2, PEA3, GSG element and Egr-1, and was highly G/C-rich. The promoter activity of this 5′-upstream region was demonstrated by transfecting its fusion-construct with the E. coli β-galactosidase gene into the F9 mouse teratocarcinoma cell line. The 5′ ends of the mRNA were mapped to at least two positions in the 5′-upstream region. Interestingly, the 5′-upstream region exhibited a high degree of similarity to a portion of heterogeneous nuclear ribonucleo-protein (hnRNP) A2/B1 gene, which is thought to play a role in RNA processing, located in the reverse orientation to the M32 gene, and also to several known ESTs and cDNAs. These findings suggest that the 5′-upstream region of the M32 gene consists of a multiple regulatory complex which probably plays important roles in nuclear function such as chromatin organization and RNA processing.
The cognitive structure of higher functioning autism and schizophrenia: a comparative study.

The purpose of this study was to examine whether performance on a standard cognitive test-battery can be used to clearly separate higher functioning autism from schizophrenia. Revised Wechsler Intelligence Scale for Children (WISC-R) or Adults (WAIS-R) profiles of 20 autistic and 20 schizophrenic adolescent young adult subjects matched for age, sex, and IQ level were contrasted. On average, autistic individuals had higher values on the subtest "Similarities," while schizophrenic participants scored better on "Comprehension. " Discriminant analysis showed that a prognosis of the psychiatric classification can be made with 82.5% accuracy if all subscale data are considered. Even though this finding probably has limited merit for making judgements in clinical practice, it might be of exploratory value in the pursuit of differentiating autism and schizophrenia on a cognitive level.
Anisotropy from SKS splitting across the Pacific-North America plate boundary offshore southern California

SKS arrivals from ocean bottom seismometer (OBS) data from an offshore southern California deployment are analysed for shear wave splitting. The project involved 34 OBSs deployed for 12 months in a region extending up to 500 km west of the coastline into the oceanic Pacific plate. The measurement process consisted of removing the effects of anisotropy using a range of values for splitting fast directions and delay times to minimize energy along the transverse seismometer axis. Computed splitting parameters are unexpectedly similar to onland parameters, exhibiting WSW–ENE fast polarization directions and delays between 0.8 and 1.8 s, even for oceanic plate sites. This is the first SKS splitting study to extend across the entire boundary between the North America and Pacific plates, into the oceanic part of the Pacific plate. The splitting results show that the fast direction of anisotropy on the Pacific plate does not align with absolute plate motion (APM), and they extend the trend of anisotropy in southern California an additional 500 km west, well onto the oceanic Pacific plate. We model the finite strain and anisotropy within the asthenosphere associated with density–buoyancy driven mantle flow and the effects of APM. In the absence of plate motion effects, such buoyancy driven mantle flow would be NE-directed beneath the Pacific plate observations. The best-fit patterns of mantle flow are inferred from the tomography-based models that show primary influences from foundering higher-density zones associated with the history of subduction beneath North America. The new offshore SKS measurements, when combined with measurements onshore within the plate boundary zone, indicate that dramatic lateral variations in density-driven upper-mantle flow are required from offshore California into the plate boundary zone in California and western Basin and Range.
The cross-sectional association between blood pressure and Alzheimer's disease in a biracial community population of older persons.

BACKGROUND The relation of blood pressure to Alzheimer's disease (AD) is complex because both an association of high blood pressure with increased risk of the disease and lower blood pressure as a consequence of the disease are possible. METHODS We examined the cross-sectional association of blood pressure and AD in the Chicago Health and Aging Project (CHAP), a study of a geographically defined, biracial community. After in-home interviews with 6.162 residents > or =65 years, a stratified random sample of 729 participants was clinically evaluated; 709 had blood pressures measured, and 243 were diagnosed with AD. RESULTS In logistic regression models adjusted for age, sex, education, and race there was no association between blood pressure measured as a continuous variable and Alzheimer's disease. In categorical analyses, however, prevalence of Alzheimer's disease was significantly higher among persons with low systolic pressure (<130 mmHg) compared with the referent group of 130-139 mmHg (odds ratio [OR] = 2.2, 95% confidence interval [CI]: 1.2,4.1), and with low diastolic pressure (<70 mmHg) compared to the referent of 70-79 mmHg (OR = 1.8, 95% CI: I. 1,3.1). High systolic and diastolic categories were not statistically different from the referent group, although there was some evidence that the associations differed by race. The odds ratios changed little with further adjustment for apolipoprotein E genotype, antihypertensive medications, body mass, stroke, diabetes, and heart disease. CONCLUSION These findings are consistent with previous studies showing associations between low blood pressure and AD, but longitudinal studies are needed to characterize cause-and-effect associations.
Unsupervised learning of indoor localization based on received signal strength

Most indoor wireless sensor network localization methods require costly site surveys to collect fingerprint information for later comparison. Moreover, due to the dynamic nature of fingerprint information in indoor wireless environments, the need for site surveys may be ongoing. In this work, indoor localization is addressed with an unsupervised learning algorithm. Our novel algorithm based on received signal strength combines the information conveyed by both range-based and range-free localization with state-of-art optimization techniques. A specially designed hierarchical Bayesian hidden Markov model coupled with a particle filter helps mitigate non-line-of-sight and multipath errors. This grid-based data sample process, derived from the theory of Dirichlet processes, simplifies the global optimization problem of unsupervised learning by employing a single initial hyper-parameter. Meanwhile, for obtaining accurate coordinates of mobile nodes, a unique semidefinite programming method is used to provide feedback to the radio propagation model. This feedback step can enable the grid-based algorithms not only to establish the coordinates of a mobile node, but also to optimize the accuracy iteratively. Theoretical and experimental analyses indicate that the proposed algorithm can achieve better localization accuracy than conventional range-based algorithms without adding computation cost.

Technology Acceptance And E-Learning Performance In A Non-Technology-Intensive Course

Prior research suggests that individuals’ technology acceptance levels may affect their performance outcomes when relying on technology in both work and learning environments. Most previous research investigating the relationship between individual attitudes towards technology and learning has been conducted in technology-intensive settings. In this study we investigate the relationship between individuals’ technology acceptance factors and their performance in a non-technology intensive course – an introductory accounting course where technology is used as a learning tool but where knowledge of technology is not a primary learning objective. Results show that individuals with lower levels of academic proficiency are likely to perform worse if they are also less accepting of technology, compared to their relative peers with higher levels of technology acceptance.
SAR Image Content Retrieval Based on Fuzzy Similarity and Relevance Feedback

This paper presents a new content-based synthetic aperture radar (SAR) image retrieval method to search out SAR image patches, which consists of two essential parts: an initial retrieval and later refined results. To obtain the proper initial retrievals, we develop a similarity measure named region-based fuzzy matching (RFM) to evaluate the similarities between SAR image patches. First, to reduce the negative influence of speckle noise, we segment the SAR image patches into brightness-texture regions at the superpixel level rather than the pixel level. Second, a multiscale edge detector is utilized to resolve the multiscale property of the SAR image patches, and then the edge regions of the SAR image patches are defined by those edge features. Third, to overcome the segmented uncertainty and the blurry boundaries, the obtained regions are described by fuzzy features. Finally, the RFM similarity between two SAR image patches is converted into the linear summation of the resemblance between different fuzzy feature sets. After we obtain the initial retrieval results, the multiple relevance feedback (MRF) scheme is proposed to refine the original ranked list. In this scheme, different relevance feedback approaches are carried out respectively, and then their results are fused to improve the initial retrieval. In addition, a new kernel function based on the RFM measure is developed for MRF. The encouraging experimental results counted on a manually constructed ground truth SAR image patch dataset demonstrate that our retrieval method is effective for SAR images compared with some existing approaches proposed in the remote sensing community
Purification and characterization of pili isolated from Vibrio parahaemolyticus Na2

Pili from Vibrio parahaemolyticus Na2 isolated from a patient with diarrhea were purified and characterized. The organisms were hemagglutinative, but the purified pili were not. Na2 pili were physicochemically and immunologically quite different from the previously described V. parahaemolyticus Ha7 pili. Nevertheless, there was a high degree of homology between their N-terminal amino acid sequences.
