Efficient Retrieval on Dense Vector by Similarity Preserve Hash in Vegetable Geographical Origin Identification System

Summary Recently, camouflaging geographical origin of agricultural products is a major problem in Japan. Therefore, we developed a distributed geographical origin identification system which identifies cultivated farms of vegetables by using trace element compositions of vegetables. This system stores compositions of trace, or very small quantities of elements into database which located on farming districts, and compares them to trace element compositions of vegetables which gathered from food distribution channel such as markets, food factories. The comparison is done by calculating correlation coefficient. This system can be considered as an information retrieval system which gives only an answer of which trace element composition is similar to given query vegetable's trace element composition. In this system, trace element compositions are expressed as dense vector, and they are retrieved by one-to-one comparison. In this paper, we describe applying Similarity Preserve Hash (SPH) into our geographical origin identification system, with assumption on data disposition.
Phragmites australis in North America and Europe Photosynthesis of co-existing Phragmites haplotypes in their non-native range : are characteristics determined by adaptations derived from their native origin ?

The Gulf Coast of North America (GC) is a ‘hot spot’ of Phragmites diversity as several lineages (defined according to the haplotypes of their chloroplast DNA) differing in origin, genetic traits and phenotype co-exist and interbreed in this area. We analysed differences in photosynthetic characteristics among and within four haplotypes to understand if differences in gas exchange can be attributed to adaptations acquired in their native ranges. We collected rhizomes of four GC haplotypes (I2, M1, M and AI; including the phenotypes ‘Land-type’, ‘Delta-type’, ‘EU-type’ and ‘Greeny-type’) and propagated them in a common controlled environment to compare photosynthesis–irradiance responses, CO2 responses, chlorophyll fluorescence, the activity of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), specific leaf area (SLA), pigment contents, stomatal density and guard cell length. The maximum light-saturated photosynthetic rate, Amax, in the haplotype I2 (Land-type) and haplotype M1 (Delta-type) (34.3–36.1 mmol CO2 m 22 s) was higher than that in the invasive Eurasian haplotype M (22.4+2.3 mmol CO2 m 22 s). The Amax of haplotype AI (Greeny3-type) was 29.1+4.0 mmol CO2 m 22 s and did not differ from the Amax of the other haplotypes. The carboxylation rate (Vcmax) and electron transport rate (Jmax) followed the same pattern as Amax. The haplotypes also differed in SLA (17.0–24.3 m 2 kg dry mass) and pigment content, whereas stomatal density and guard cell length, Rubisco activity and chlorophyll fluorescence did not differ significantly among haplotypes. The high photosynthetic activity and gas-exchange capacity of the two haplotypes originating in tropical Africa and the Mediterranean area (haplotypes I2 and M1) are apparently adaptations derived from their native ranges. Hence, the haplotypes can be regarded as ecotypes. However, it remains unclear how these differences relate to plant competitiveness and fitness in the GC of North America environment.
Serglycin Is Implicated in the Promotion of Aggressive Phenotype of Breast Cancer Cells

Serglycin is a proteoglycan expressed by some malignant cells. It promotes metastasis and protects some tumor cells from complement system attack. In the present study, we show for the first time the in situ expression of serglycin by breast cancer cells by immunohistochemistry in patients’ material. Moreover, we demonstrate high expression and constitutive secretion of serglycin in the aggressive MDA-MB-231 breast cancer cell line. Serglycin exhibited a strong cytoplasmic staining in these cells, observable at the cell periphery in a thread of filaments near the cell membrane, but also in filopodia-like structures. Serglycin was purified from conditioned medium of MDA-MB-231 cells, and represented the major proteoglycan secreted by these cells, having a molecular size of ∼250 kDa and carrying chondroitin sulfate side chains, mainly composed of 4-sulfated (∼87%), 6-sulfated (∼10%) and non-sulfated (∼3%) disaccharides. Purified serglycin inhibited early steps of both the classical and the lectin pathways of complement by binding to C1q and mannose-binding lectin. Stable expression of serglycin in less aggressive MCF-7 breast cancer cells induced their proliferation, anchorage-independent growth, migration and invasion. Interestingly, over-expression of serglycin lacking the glycosaminoglycan attachment sites failed to promote these cellular functions, suggesting that glycanation of serglycin is a pre-requisite for its oncogenic properties. Our findings suggest that serglycin promotes a more aggressive cancer cell phenotype and may protect breast cancer cells from complement attack supporting their survival and expansion.
On the Reliability of the Color Gradient Vector Argument Approach

Today many algorithms for monochrome images have been developed based on the information provided by the gradient vector. However, these algorithms can not be applied to color images without an accurate approximation of the color gradient vector argu- ment. Moreover, there is a great number of applications that require to know with the maximum accuracy as possible the direction of the color variation in color images. This paper presents a new break- through in our work on the approximation of the argument of the color gradient vector. Taking into consideration that Hue and Satu- ration provide very useful basis for judging color uniformity, and that in the Smith's HSI color space there is a close relationship between chromaticity and how humans perceive colors, in our proposal the ar- gument of the Chromaticity gradient vector is approached based on the Hue and Saturation information. Moreover, we present a fuzzy measure of the quality or reliability of the proposed approach that, considering the inherent vagueness of the chromaticity values of the image pixels, provides us with a credibility-accuracy degree of the obtained values. Keywords— Color gradient, Color image processing, Gradient argument, Gradient reliability, Gradient vector.

A New Hierarchical Resource Searching Model in P 2 P Network

As a typical form of resource-searching model in Peer to Peer (P2P) network, the Gnutella model has advantages of strong robustness and anti-destruction, high speed and efficiency, but there exists problem of heavy network load. A new hierarchical resource-searching model based on logical layering mechanism is presented. The performance analysis and simulation results show that the proposed hierarchical searching model, compared with the Gnutella model, has less network load and better characteristic of shorter average searching response time.
Evaluation of frequency, type, and function of gap junctions between skeletal myoblasts overexpressing connexin43 and cardiomyocytes: relevance to cell transplantation

Cell transplantation of skeletal myoblasts (SMs) is one possible treatment for repairing cardiac tissue after myocardial injury. However, inappropriate electrical coupling between grafted SMs and host cardiomyocytes may be responsible for the arrhythmias observed in clinical trials of SM transplantation. Whether functional gap junctions occur between the two cell types remains controversial. We have studied the ability of SMs to electrically couple with isolated adult rat cardiomyocytes (CMs) and assessed whether connexin43 (Cx43) overexpression enhanced gap junctional conductance (Gj). C2C12 myoblast lines overexpressing Cx43 were generated by gene transfection and clonal selection. CMs were cocultured with either SMs overexpressing Cx43 (CM‐SMCx43) or control SMs (CM‐SMWT) in vitro. Gj between pairs of SMs and CMs was quantified with dual whole cell patch clamping. Formation of Gj occurred between 22% of CM‐SMWT pairs (n=73) and 48% of CM‐SMCx43 pairs (n=71, P<0.001). The Gj of CM‐SMCx43 pairs (29.7±4.3 nS, n=21) was greater than that of CM‐SMWT pairs (14.8±2.0 nS, n=12, P<0.05). The overexpression of Cx43 in SMs increased the formation of electrical communication and the steady‐state conductance between SMs and CMs. Enhanced gap junctional conductance may be useful to promote the integration of transplanted SMs into the myocardium.
Characterization of the Kynurenine Pathway in Human Neurons

The kynurenine pathway is a major route of l-tryptophan catabolism producing neuroactive metabolites implicated in neurodegeneration and immune tolerance. We characterized the kynurenine pathway in human neurons and the human SK-N-SH neuroblastoma cell line and found that the kynurenine pathway enzymes were variably expressed. Picolinic carboxylase was expressed only in primary and some adult neurons but not in SK-N-SH cells. Because of this difference, SK-N-SH cells were able to produce the excitotoxin quinolinic acid, whereas human neurons produced the neuroprotectant picolinic acid. The net result of kynurenine pathway induction in human neurons is therefore predicted to result in neuroprotection, immune regulation, and tumor inhibition, whereas in SK-N-SH cells, it may result in neurotoxicity, immune tolerance, and tumor promotion. This study represents the first comprehensive characterization of the kynurenine pathway in neurons and the first description of the involvement of the kynurenine pathway as a mechanism for controlling both tumor cell neurotoxicity and persistence.
Dermatoglyphic Evidence of Fluctuating Asymmetry in Schizophrenia

Fluctuating asymmetry provides a measure of an organism's capacity to buffer adverse factors that could disturb its development. It is estimated from the differences between theoretically identical right- and left-sided structures. Dermatoglyphic fluctuating asymmetry has been recently used to investigate developmental disorders. Fingerprints and palm prints of schizophrenic patients, which had been the subjects of an earlier report of conventional dermatoglyphic trait frequencies, were reanalysed to determine their level of fluctuating asymmetry. A review of the diagnostic protocols and clinical records used in the original study indicated that most of the 482 subjects would have met DSM–III–R criteria for schizophrenia. The schizophrenic sample had significantly higher levels of fluctuating asymmetry on four dermatoglyphic traits, the finger-ridge counts, fingerprint patterns, the palmar atd angles and palmar a-b ridge counts, than controls. This finding supports the results of two earlier studies, and its relevance to the roles of genetics, foetal insults, and developmental anomalies of the brain in the aetiology of schizophrenia is discussed.
KNN Query Processing 0 f Secured Multi Data Owner Using Voronoi Diagram

an economical and flexible way to data owners for delivering spatial data to users of location-based services would be Outsourcing spatial databases to the cloud. In this data outsourcing model the service provider can be untrustworthy. It may return incorrect or incomplete query results to clients intentionally or not. Ensuring spatial query integrity is critical. Here an efficient road network is proposed, with k-nearest-neighbor query verification technique which utilizes the network Voronoi diagram and neighbors to prove the integrity of query results. To deal with data integrity and authentication problem for outsourced databases Digital Signature is used. This Technique verifies both the distances and the shortest paths from the query point to its kNN results on the road network. Data owner builds an authenticated data structure before providing the data to the service provider. Knearest-neighbor query verification technique utilizes the network Voronoi diagram and neighbors to prove the integrity of query results in ROAD Network.Skyline queries take into account both the spatial and non-spatial attributes of the points. For example instead of considering all the hotels, a nearest neighbor query would instead ask for the hotel that is closest to among those who provide services such as pool, internet at the same time. Keywords— data outsourcing, location based services, service provider, road network, voronoi diagram, skyline queries.
Path Planning for Aircraft Fuel Tank Inspection Robot Based on Region Division

Path planning is indispensable in performing the inspection task using continuum robot in the environment like aircraft fuel tank. In order to obtain the optimal path and make it feasible for the robot traversal, a path planning strategy based on region division is put forward. The aircraft fuel tank is divided into several regions and mapped to a two-dimension plane by using dimension reduction which can reduce computation complexity. Three numerical methods are proposed in terms of different regions where the target point locates, and the shortest telescopic distance of the inspection robot can be solved. With bending and rotating of the inspection robot, the three methods ensure arbitrary point in the single cabin can be achieved. Simulation experiments are implemented on Matlab, and the accuracy, the effectiveness and feasibility of the algorithm are verified. Copyright © 2014 IFSA Publishing, S. L.
A Combinatorial Formula for Orthogonal Idempotents in the 0-Hecke Algebra of the Symmetric Group

Building on the work of P.N. Norton, we give combinatorial formulae for two maximal decompositions of the identity into orthogonal idempotents in the $0$-Hecke algebra of the symmetric group, $\mathbb{C}H_0(S_N)$. This construction is compatible with the branching from $S_{N-1}$ to $S_{N}$.

Finding Multiple Basin Modes in a Linear Ocean Model

Abstract A method for finding the most unstable eigenmodes in linear models using the breeding technique was developed. The breeding technique was extended to allow for the calculation of complex eigenvalues and eigenvectors of the linear model operator without involving computationally expensive matrix manipulations. While the breeding method finds the most unstable modes, multiple planetary basin modes may be found by removing the leading modes using the adjoint model. To test the sensitivity of basin modes to model formulation, the method was applied for the calculation of the gravest planetary basin modes in a reduced-gravity linear shallow water model with complex basin geometry and background circulation. It was found that the leading basin modes are not sensitive to the form of the dissipation or model resolution, suggesting that the decadal modes are robust. However, the properties of the low-frequency modes are strongly affected by the basin geometry and the mean flow.
The C*-algebra of an affine map on the 3-torus

We study the C*-algebra of an affine map on a compact abelian group and give necessary and sufficient conditions for strong transitivity when the group is a torus. The structure of the C*-algebra is completely determined for all strongly transitive affine maps on a torus of dimension one, two or three.
A review of hydrothermal liquefaction bio-crude properties and prospects for upgrading to transportation fuels

Hydrothermal liquefaction (HTL) presents a viable route for converting a vast range of materials into liquid fuel, without the need for pre-drying. Currently, HTL studies produce bio-crude with properties that fall short of diesel or biodiesel standards. Upgrading bio-crude improves the physical and chemical properties to produce a fuel corresponding to diesel or biodiesel. Properties such as viscosity, density, heating value, oxygen, nitrogen and sulphur content, and chemical composition can be modified towards meeting fuel standards using strategies such as solvent extraction, distillation, hydrodeoxygenation and catalytic cracking. This article presents a review of the upgrading technologies available, and how they might be used to make HTL bio-crude into a transportation fuel that meets current fuel property standards.
Thyroid Autoimmunity and Behçet's Disease: Is There a Significant Association?

Background. Behcet's disease (BD) could be regarded as an autoimmune disease in many aspects. Autoimmune thyroid disease (ATD) is frequently accompanied by other various autoimmune diseases. Nevertheless, there is not still enough data showing the association between BD and ATD. In addition, no controlled study is present in the PubMed, which evaluates thyroidal autoimmunity using antithyroid peroxidase antibody in a large series of patients with BD. Methods. We aimed to investigate the frequency of ATD in patients with BD. The study included 124 patients with BD and 99 age- and sex-matched healthy volunteers. Results. Autoimmune thyroiditis was noted in 21 cases (16.9%) with BD. In the control group, 22 cases (22.22%) were diagnosed as autoimmune thyroiditis. There was no difference between the groups in respect to thyroid autoantibodies (P > 0.05). There were no statistically significant differences between baseline TSH levels of the BD patients and of the controls (P > 0.05). Statistically, the mean serum free T4 levels of the patients with BD were higher than those of the controls (P < 0.001). Conclusions. No association could be found between BD and ATD. Therefore, it is not of significance to investigate thyroid autoimmunity in BD.
Exclusion-inclusion based text categorization of biomedical articles

In this paper, we propose a new approach based on two original principles to categorize biomedical articles. On the one hand, we combine linguistic, structural and metric descriptors to build patterns stemming from data mining techniques. On the other hand, we take into account the importance of the absence of patterns to the categorization task by using an exclusion-inclusion method. To avoid a crisp effect between the absence and the presence of a pattern, the exclusion-inclusion method uses two regret measures to quantify the interest of a weak pattern according to the other classes and among patterns from a same class. The global decision is based on the generalization of the local patterns, firstly by using patterns excluding classes, then according to the regret ratios. Experiments show the effectiveness of the approach.
KNOWLEDGE SHARING SYSTEMS AND CULTURAL IDENTITY IN ORGANIZATIONS

Purpose – Knowledge is only as good as its transfer mechanism. Physiological roadblocks can inhibit knowledge or information transfer flow between the sexes. Through today’s (2014) streaming information technology systems, knowledge is shared in an open arbitrary methodology. Communicator’s tend to blame the audience for not accepting a message, but it is often that the sender, encoding process or channels chosen were not applied correctly. Everything is systematic and structured for efficiency of use, but not comprehension. This paper will seek to understand knowledge transfer “noises” and comprehension disengagements in organizational tacit or silent knowledge transfers.
Music and Dyslexia: A New Musical Training Method to Improve Reading and Related Disorders

Numerous arguments in the recent neuroscientific literature support the use of musical training as a therapeutic tool among the arsenal already available to therapists and educators for treating children with dyslexia. In the present study, we tested the efficacy of a specially-designed Cognitivo-Musical Training (CMT) method based upon three principles: (1) music-language analogies: training dyslexics with music could contribute to improve brain circuits which are common to music and language processes; (2) the temporal and rhythmic features of music, which could exert a positive effect on the multiple dimensions of the “temporal deficit” characteristic of some types of dyslexia; and (3) cross-modal integration, based on converging evidence of impaired connectivity between brain regions in dyslexia and related disorders. Accordingly, we developed a series of musical exercises involving jointly and simultaneously sensory (visual, auditory, somatosensory) and motor systems, with special emphasis on rhythmic perception and production in addition to intensive training of various features of the musical auditory signal. Two separate studies were carried out, one in which dyslexic children received intensive musical exercises concentrated over 18 h during 3 consecutive days, and the other in which the 18 h of musical training were spread over 6 weeks. Both studies showed significant improvements in some untrained, linguistic and non-linguistic variables. The first one yielded significant improvement in categorical perception and auditory perception of temporal components of speech. The second study revealed additional improvements in auditory attention, phonological awareness (syllable fusion), reading abilities, and repetition of pseudo-words. Importantly, most improvements persisted after an untrained period of 6 weeks. These results provide new additional arguments for using music as part of systematic therapeutic and instructional practice for dyslexic children.
Evaluation of cardiac involvement during dengue viral infection.

BACKGROUND Dengue is a disease whose clinical manifestations range from asymptomatic infections to a severe disease. There have been some previous reports of myocardial involvement in dengue, but this association has not been completely established. METHODS From January to July of 2011, patients hospitalized with dengue, confirmed through dengue nonstructural protein 1 and/or immunoglobulin M detection, were included in this study and troponin I and N terminal fragment of B-type natriuretic peptide levels were determined. Patients with abnormal biomarkers underwent echocardiography and when any abnormality was detected, they underwent cardiac magnetic resonance imaging. RESULTS Eighty-one patients were evaluated and 12 patients (15%) presented with elevated biomarker levels. Compared to controls, they had higher leukocyte (P < .001) and platelet counts (P = .005); higher C-reactive protein (P = .02), and a lower viral load (P = .03). There was no difference according to clinical dengue classification; dengue hemorrhagic fever/dengue shock syndrome severity; duration of symptoms; or prevalence of secondary infection between the 2 groups. Two patients died secondary to cardiogenic shock before imaging studies. Necroscopic findings were compatible to myocarditis in both, and immunohistochemistry for dengue virus showed increased staining on mononuclear cells located in the myocardial tissue. Of the 10 patients who underwent echocardiography, depressed left ventricular ejection fraction (LVEF) was identified in 1, left ventricular segmental abnormalities with preserved LVEF in 2, and an important pericardial effusion with tamponade in another. Cardiac involvement was confirmed by CMR in these 4 patients. CONCLUSIONS Dengue viruses were shown to cause cardiac disease with clinical manifestations ranging from mild elevation of biomarkers to myocarditis and/or pericarditis.
