Multibiometric based authentication using feature level fusion

Security is the most important thing in the world. Password is used for security but it does not provide the effective security. So single biometric is preferred but due to lack of reliability, it is not efficient. So Multibiometric is used. Multibiometric provides more reliability. Fingerprint and Iris are the most unique features because it is unchangeable anywhere most of the time, compare to other biometrics. In the proposed approach 5 steps are followed in enrollment phase i) Feature extraction of fingerprint and iris ii) Fusion of extracted features iii) Key is generated from the fused feature which is of greater than 128 bit which is enough for AES encryption iv) AES encryption v) Hash Encoding vi) AES decryption. Message is subjected to hash and hash of message is obtained and it is given to AES encryption as a message and the key is obtained from the fused feature. In the verification phase, decryption is to be done. Message is obtained when the encrypted value from the enrollment phase and verification phase are same. Fingerprint is obtained from publicly available sources and Iris is obtained from CASIA Iris database. From this system performance of False acceptance rate and False rejection rate are highly reduced.
Structure of a ternary complex of proteinase K, mercury, and a substrate‐analogue hexa‐peptide at 2.2 Å resolution

The crystal structure of a ternary complex of proteinase K, Hg(II) and a hexapeptide N‐Ac‐Pro‐Ala‐Pro‐Phe‐Pro‐Ala‐NH2 has been determined at 2.2 Å resolution and refined to an R factor of 0.172 for 12,910 reflections. The mercury atom occupies two alternate sites, each of which was assigned an occupancy of 0.45. These two sites are bridged by Cys‐73 Sγ which forms covalent bonds to both. Both mercury sites form regular polyhedrons involving atoms from residues Asp‐39, His‐69, Cys‐73, His‐72, Met‐225, and Wat‐324. The complex formation with mercury seems to disturb the stereochemistry of the residues of the catalytic triad Asp‐39, His‐69, and Ser‐224 appreciably, thus reducing the enzymatic activity of proteinase K to 15%. The electron density in the difference Fourier map shows that the hexapeptide occupies the S1 subsite predominantly and the standard recognition site constituted by Ser‐132 to Gly‐136 and Gly‐100 to Tyr‐104 segments is virtually empty. The hexapeptide is held firmly through a series of hydrogen bonds involving protein atoms and water molecules. As a result of complex formation, Asp‐39, His‐69, Met‐225, Ile‐220, Ser‐219, Thr‐223, and Ser‐224 residues move appreciably to accommodate the mercury atoms and the hexapeptide. The largest movement is observed for Met‐225 which is involved in multiple interactions with both mercury and the hexapeptide. The activity results indicate an inhibition rate of 95%, as a result of the combined effect of mercury and hexapeptide. © 1996 Wiley‐Liss, Inc.
Ionic transport in the fish gill epithelium

The gill of fishes is modified for gas exchange, thereby providing a site for net movement of salts and water down their respective gradients. Specialized cells in the gill epithelium are joined by tight junctions of variable depth and express a variety of transporters and channels. These cells mediate NaCl extrusion in marine fishes and NaCl uptake in freshwater fishes. These transport steps also provide pathways for the extrusion of ammonia and acid vs. base equivalents.
Regulation of Expression of ob mRNA and Protein by Glucocorticoids and cAMP (*)

Regulation of obese gene (ob) expression in ob/ob and db/db mice and in cultured rat adipocytes was examined. It has been demonstrated that exogenous human OB protein (leptin) treatment reduces food intake and weight gain, as well as insulin, glucose, and corticosterone levels in ob/ob mice. In the present report we show that leptin treatment down-regulates endogenous adipose ob mRNA. However, treatment of isolated rat adipocytes with 100 ng/ml human or murine leptin had no direct effect on expression of endogenous ob mRNA, suggesting that leptin may be able to down-regulate its own expression by an indirect, non-autocrine mechanism. Glucocorticoids increased both ob mRNA levels and secreted leptin levels in vitro. Conversely, agents that increase intracellular cAMP, such as β-adrenergic agonists or BtcAMP itself, decreased ob mRNA expression and leptin secretion. Therefore, increased glucocorticoid levels and decreased sympathetic neural activity may contribute to the elevated ob mRNA expression observed in genetically obese, hyperglucocorticoid rodents. Furthermore, leptin might regulate its own expression through a feedback mechanism involving the hypothalamic pituitary axis.
Determining zygosity in the Vietnam Era Twin Registry: an approach using questionnaires

The Vietnam Era Twin Registry (VETR) is a registry of 7375 American male veteran twin pairs born between 1939 and 1955 who served in the armed forces of the United States between 1964 and 1975. Optimal use of registry data requires the determination of zygosity. Two approaches are available: analysis of blood genetic marker systems and responses of twins to questions about sibling similarity. Zygosity for the VETR was determined using the questionnaire technique supplemented with blood group typing data abstracted from military records. After comparing four alternative zygosity assignment methods, a logistic regression technique which uses discriminating variables based on race was selected. The approach is similar to that described by Magnus et al. (1983) in their study of Norwegian twins, suggesting that questionnaire responses are independent of nationality and reinforcing the reliability of the questionnaire method for zygosity ascertainment.
E1B55K-Deleted Adenovirus (ONYX-015) Overrides G1/S and G2/M Checkpoints and Causes Mitotic Catastrophe and Endoreduplication in p53-Proficient Normal Cells

In order to take advantage of cell replication machinery, viruses have evolved complex strategies to override cell cycle checkpoints and force host cells into S phase. To do so, virus products must interfere not only with the basal cell cycle regulators, such as pRb or Mad2, but also with the main surveillance pathways such as those controlled by p53 and ATM. Recently, a number of defective viruses has been produced which, lacking the latter ability, are incapable of replicating in normal cells but should be able to grow and finally lyse those cells that, such as the tumor cells, have lost their surveillance mechanisms. A prototype of these oncolytic viruses is the E1B55K-defective Adenovirus ONYX-015, which was predicted to selectively replicate and kill p53-deficient cancer cells. We found that, despite wt p53 and notwithstanding the activation of the checkpoint regulators p53, ATM, and Mad2, ONYX-015 actively replicated in HUVEC cells. Furthermore, ONYX-015 replication induced a specific phenotype, which is distinct from that of the E4-deleted adenovirus dlE4 Ad5, although both viruses express the main regulatory region E1A. This phenotype includes overriding of the G1/S and G2/M checkpoints, over-expression of MAD2 and retardation of mitosis and accumulation of polyploid cells, suggesting the occurrence of alterations at the mitotic-spindle checkpoint and impairment of the post-mitotic checkpoint. Our data suggest that viral E1A and E4 region products can override all host cell-checkpoint response even at the presence of a full activation of the ATM/p53 pathway. Furthermore, the E4 region alone seems to act independently of the E1B55K virus product in impairing the ATM-dependent, p53-independent G2/M checkpoint since dlE4 Ad5-infected cells arrested in G2 while ONYX-015-infected cells did enter mitosis.
Associations between General Parenting Styles and Specific Food-Related Parenting Practices and Children's Food Consumption

Purpose. Explore the impact of general parenting style and specific food-related parenting practices on children's dietary habits. Design. Cross-sectional study of sixth graders and their parents. Setting. Data were gathered (in 2003) in 69 of 100 randomly selected elementary schools in Belgium. Subjects. All sixth graders (N = 1957) were invited to participate; 82.4% of their parents gave consent and completed questionnaires, resulting in 1614 parent-child pairs. Measures. Children's consumption of breakfast, fruit, vegetables, soft drinks, and sweets was assessed by self-administered food frequency questionnaires. Parents completed questionnaires on sociodemographic characteristics, general parenting styles (authoritarian, authoritative, indulgent, or neglecting) and specific food-related parenting practices (pressure, reward, encouragement through negotiation, catering on children's demands, permissiveness, avoiding negative modeling, and praise). Analysis. Logistic regression analyses were performed, with general parenting style and specific food-related parenting practices as predictors and dietary habits as dependent variables, controlling for sociodemographic characteristics and children's weight status. Results. General parenting style did not show any significant impact on dietary habits. In contrast, the food-related parenting practice “encouragement through negotiation” showed a significant positive impact, whereas “pressure,” “catering on demand,” and “permissiveness” were practices with an unhealthy impact. Conclusion. Nutrition education programs that guide parents in firm but not coercive food parenting skills are likely to have a positive impact upon children's dietary habits.
Mimi4x: An interactive audio-visual installation for high-level structural improvisation

We present Mimi4x, an interactive audio-visual installation that engages members of the general public in high-level structural decision-making in musical improvisation. Through a MIDI controller, the user manages four instances of the Mimi 1.5 improvisation system. The visuals in each Mimi system animate the generation of new music, depicting the recombination of musical material, and the flow of generated music in time. A composer prepares original music material for each Mimi to use in its improvisation. Through Mimi4x, the user is directly involved in the improvisation/composition process, and takes on some of the role of the composer. The user chooses which oracles will perform and when, and can adjust the recombination rate for, and playback volume of, each oracle during performance. This simple method of interaction is accessible to all users regardless of their musical background, yet gives the user significant and satisfying influence over the music generated.

Healthy subjects with a family history of alcoholism show increased stimulative subjective effects of alcohol.

BACKGROUND Research has shown that subjects with a family history positive (FHP) of alcoholism are at increased risk for alcoholism and that this group reacts differently to alcohol than family history negative (FHN) subjects. These different levels of sensitivity may make FHP persons more likely to consume alcohol. Here, we tested the hypothesis that subjects FHP for type 1 alcoholism (according to Cloninger) are more sensitive than control subjects to the stimulative, properties of alcohol following a single moderate dose of alcohol. METHODS Fifty-one healthy men and women (22 FHP and 29 FHN) participated in 2 laboratory sessions, in which they consumed a beverage containing ethanol (0.6 g/kg in juice) or placebo (juice alone) in a randomized order. Primary dependent measures were self-report questionnaires of mood states. RESULTS Subjects with family history of type 1 alcoholism showed increased stimulative responses and an elevated positive mood state after ethanol compared to controls. CONCLUSIONS At this moderate dose, ethanol increased stimulative subjective responses in individuals who were "family history positive. " This enhanced sensitivity could motivate to exaggerated drinking and thereby increase the risk for developing alcoholism.
Dubble or Nothing? Is HAUSP Deubiquitylating Enzyme the Final Arbiter of p53 Levels?

Signal transduction processes can be regulated by biochemical modifications that affect protein activity or localization and by protein stability. Proteins implicated in cancer, such as β-catenin and p53, are regulated by a combination of posttranslational modifications and protein degradation by the ubiquitin-proteasome pathway. Wood explores how ubiquitylation of these proteins may not be as unidirectional as previously thought. With the identification of substrate-specific deubiquitylating enzymes, ubiquitylation may not always lead to protein destruction, but may provide another finely tunable step for controlling protein activity.
Metabolic changes associated with the germination of corn. II. Nucleic acid metabolism.

using a reciprocal grafting experiment. The materials studied were cherry-red and red-free selections from N. tabacwniiz cv. 401 and their hybrids with N. sylvestris. Flue-curing decreased the nicotine, total alkaloid content, and the ratio of nicotine to total alkaloid content and increased the nornicotine content in converter entries whereas the alkaloid composition of the nonconverter entry remained essentially unchanged. Grafting per se did not influence the level of alkaloid production in these materials. The degree of conversion and alkaloid production in a scion or host was not influenced by the other graft component. The entries serving either as scion or host exhibited increasing conversion capability in the order RF, RFX, CR, and CRX. In their ability to supply scions with alkaloid the entries differed in the increasing order CRX, RFX, CR, and RF. Nornicotine was not transferred from the scion to host in the case of converter scions developed on a red-free host. Conversion capability is associated with genotype. Those entries with 2 genes for conversion (CR and CRX) exhibited a greater degree of conversion than the 1 gene type (RFX). Literature Cited
Anomaly Detection with Virtual Service Migration in Cloud Infrastructures

Cloud computing is becoming a very popular way to outsource data storage, services or even infrastructure. Clouds are large network data centers that make use of virtualization technology, thus enabling dynamic scalability and , from user’s perspective, apparent infinite resources. Clouds host services in virtual machines that are isolated from one another and can be migrated within or between data centers. Virtual service migration is used in case of failure or disaster, resource optimization issues, maintenance and to reduce network costs. This thesis work shows how virtual service migration affects state-of-the-art anomaly detection that can be used to detect malicious activity, such as Distributed Denial of Service attacks. Using data from actual services, anomalous traffic is analyzed with and without migration in different scenarios. The scenarios cover different types of anomalies, i.e. attacks, variations of anomaly intensity and variations of size of migrated services. All these parameters affect how much virtual service migration influences anomaly detection results. Our results show that, in some cases, virtual service migration can be incorrectly detected as an anomaly, i.e., an attack. To mitigate this, one could adjust detection parameters such as the anomaly score threshold to reduce the number of incorrectly detected attacks. However, this introduced the risk of not detecting genuine attacks. This finding brings into question the reliability of state-of-the-art anomaly detection techniques when applied in the cloud, pointing to the need for further investigation in this important area.
Stopwords Identification by Means of Characteristic and Discriminant Analysis

Stopwords are meaningless, non-significant terms that frequently occur in a document. They should be removed, like a noise. Traditionally, two different approaches of building a stoplist have been used: the former considers the most frequent terms looking at a language (e.g., english stoplist), the other includes the most occurring terms in a document collection. In several tasks, e.g., text classification and clustering, documents are typically grouped into categories. We propose a novel approach aimed at automatically identifying specific stopwords for each category. The proposal relies on two unbiased metrics that allow to analyze the informative content of each term; one measures the discriminant capability and the latter measures the characteristic capability. For each term, the former is expected to be high in accordance with the ability to distinguish a category against others, whereas the latter is expected to be high according to how the term is frequent and common over all categories. A preliminary study and experiments have been performed, pointing out our insight. Results confirm that, for each domain, the metrics easily identify specific stoplist wich include classical and category-dependent stopwords.
Assessing Data Quality for Geographical Information System Databases

GIS is a tool for spatial-related data processing and decision making. Handling decision making under high quality data is a further extension of GIS functions. Therefore, it is of vital importance to assess data quality in GIS and to decide the fitness of data to user's particular applications. We present a methodology to determine two data quality characteristics - accuracy and completeness - that are of critical importance to decision makers. We examine how the quality metrics of source data affect the quality for information outputs produced using the relational algebra operations Selection, Projection, and Cartesian product. Our methodology can help users deciding the fitness of spatial data to their GIS applications according to the quality levels much efficiently.
Effectiveness of acute in-hospital physiotherapy with knee-extension strength training in reducing strength deficits in patients with a hip fracture: A randomised controlled trial

Question Is acute in-hospital physiotherapy with additional progressive knee-extension strength training (ST) of the fractured limb more effective in reducing knee-extension strength deficit at follow-up compared to physiotherapy without strength training in patients with a hip fracture? Design Assessor blinded, randomised controlled trial with intention-to-treat analysis. Participants 90 patients with a hip fracture admitted to an acute orthopaedic Hip Fracture Unit at a university hospital between October 2013 and May 2015. Intervention Daily physiotherapy with or without progressive knee-extension strength training (10RM), 3 x 10 repetitions, of the fractured limb using ankle weight cuffs conducted by ward physical therapists during hospital stay. Outcome measures Primary outcome was the change in maximal isometric knee-extension strength in the fractured limb in percentage of the non-fractured limb from inclusion to postoperative day 10 or discharge (follow-up). Secondary outcome was Timed Up and Go test measured early after surgery and at follow-up. Results In the intention-to-treat analysis of between-group differences, the primary outcome improved 8.1% (95% CI -2.3; 18.4) by additional strength training from baseline to follow-up. In the per-protocol analysis of non-missing data, significant between-group improvements by 10.5% (95% CI 0.3; 20.7) were found in favour of additional ST. No significant between-group differences were found in any secondary outcome. Conclusion Physiotherapy with addition of 5 sessions of ST yielded no additional improvements compared to physiotherapy without strength training in reducing the knee-extension strength deficit at follow-up in patients with a hip fracture. It is debatable whether larger improvements than the observed 8–10% can be expected given that only five exercise sessions, on average, were completed. In fragile patients with a hip fracture in the acute phase, where the ability to participate in functional exercise is compromised, we still consider early strength training a possibility to improve outcomes of clinical importance, given the results of the per-protocol analysis. The present data provides an important basis and call for future investigations including longer term interventions. Trial registration Clinicaltrials.gov NCT00848913
