Limiting Concept Spread in Environments with Interacting Concepts

The propagation of concepts in a population of agents is a form of influence spread, which can be modelled as a cascade from an initial set of individuals. In real-world environments there may be many concepts spreading and interacting. Previous work does not consider utilising concept interactions to limit the spread of a concept. In this paper we present a method for limiting concept spread, in environments where concepts interact and do not block others from spreading. We define a model that allows for the interactions between any number of concepts to be represented and, using this model, develop a solution to the influence limitation problem, which aims to minimise the spread of a target concept through the use of a secondary inhibiting concept. We present a heuristic, called maximum probable gain, and compare its performance to established heuristics for manipulating influence spread in both simulated small-world networks and real-world networks.
Effectiveness of assigning confidence levels to classifiers and a novel feature in fingerprint matching

There are different methods and techniques used for matching fingerprints but the most common and popular approach is minutiae based matching. Our approach is based on structural matching and the matching algorithm presented here is the improved and modified form of [1]. In this method, matching is done on the basis of five closest neighbors of one single minutia that is also called a center minutia. An authentication of minutia is based on these surrounding neighbors. The approach we present here is divided in to two stages. First stage performs initial filtration and the second stage includes special matching criteria that incorporate fuzzy logic as well as a novel feature to select final minutiae for matching score calculation. The method of selecting center point for second stage is also adapted. This algorithm is able to perform well for translated, rotated and stretched fingerprints and does not require any process for alignment before matching. Experimental results show that algorithm is efficient and reliable.
Commentary on Websdale

As we go into the 21st century, we can look at the past 30 years of domestic violence advocacy and research and remark proudly on how far we have come. The accumulated scientific knowledge, practitioner wisdom, policy changes, and public opinion changes are all remarkable (Klein, Campbell, Soler, & Ghez, 1997). What is even more exciting is that it looks like all that work has achieved at least partially the goal of decreasing, if certainly not yet ending, domestic violence. At the very least, we have definitely decreased the number and rate of intimate partner (IP) homicide of both men and women since 1976. However, one of the ironies in the field is that the rates of IP homicide have decreased much more for men than for women. The studies that have examined the decrease have found that a significant proportion of the decrease is attributable to increases in domestic violence resources such as hotlines and shelters and improvement in domestic violence laws (Browne, Williams, & Dutton, 1998; Dugan, Nagin, & Rosenfeld, 1999, 2003). It is also important to note in this era of marriage promotion as a solution for domestic violence that divorce availability was also associated with the decline in IP homicide in the Dugan et al. (1999) multivariate analysis. Even with IP homicide decreasing and progress apparent, every life that is lost from domestic violence is far too many and haunts all of us. Fatality reviews have increased exponentially as one way to identify ways the system can be improved to prevent these deaths. Another strategy is the development of lethality risk assessment instruments and systems. Barbara Hart (1988) led the
Étude prospective sur la capacité du KeGFR à mettre en évidence des variations du débit de filtration glomérulaire en réanimation

Introduction : l’estimation du debit de filtration glomerulaire lors de l’insuffisance renale aigue (IRA) est difficile. Les formules utilisees chez les patients ayant une insuffisance renale chronique ne sont pas applicables. Une nouvelle formule (KeGFR) incluant la production endogene de creatinine a ete proposee en 2013. Cependant peu d’etude se sont penchees sur sa validite. Notre objectif principal est d’evaluer la performance du KeGFR dans l’estimation du debit de filtration glomerulaire (eDFG) en reanimation. Nos objectifs secondaires sont d’evaluer les effets d’un haut regime de pression arterielle moyenne (PAM) sur la filtration glomerulaire chez les patients aux antecedents d’hypertension arterielle chronique (HTA). Methodes : il s’agit d’une etude prospective, observationnelle conduite d’aout 2016 a juillet 2017 a l’Hopital de Bordeaux. Nous avons inclus consecutivement tous les patients aux antecedents d’hypertension hospitalises en reanimation pour la prise en charge d’un choc septique et presentant une IRA. Les patients ont ete traites selon les recommandations standards de la sepsis campaign avec un objectif de pression arterielle moyenne individualise de 65 a 85 mmHg. Les formules d’estimation du DFG ont ete comparees via le coefficient de Spearman (ρ) et le test de Band et Altman. Resultats : nous avons inclus 26 patients. Nous retrouvons une pauvre mais significative correlation entre les formules UV/P et KeGFR pour l’estimation du DFG (ρ=0.71; P 30 ml/mn semblaient mieux repondre a une majoration de la PAM. Conclusion : il existe une faible mais neanmoins significative correlation entre les formules UV/P et KegFR, associee a une pauvre concordance. Une objectif de PAM haut a 85 mmHg chez les patients aux antecedents d’hypertension et hospitalises pour prise en charge de choc septique ameliore le rapport UV/P et ceux d’autant plus que le eDFG initial est >30ml/mn.
Nanosecond high-voltage generator

The generator consists from: capacitive energy storage (2kJ); vacuum switch (200 kA); switch controlling device (40kV); Tesla transformer (20/1); glycerin pulse forming line (2.7 Ohm): oil switch (400-750 kV) with control unit; high-voltage insulator; self-magnetically insulated vacuum line; load. The generator produces high-voltage pulses with amplitude in the range of 350-500 kV and pulse duration 10-20 ns. It is meant for powering microwave sources, vacuum diodes or X-ray sources. Calculations of the electric field strength distribution in the generator units, reliability of their operation and results of test are presented.
The DEAD-Box RNA Helicase Dbp5 Functions in Translation Termination

In eukaryotes, termination of messenger RNA (mRNA) translation is mediated by the release factors eRF1 and eRF3. Using Saccharomyces cerevisiae as a model organism, we have identified a member of the DEAD-box protein (DBP) family, the DEAD-box RNA helicase and mRNA export factor Dbp5, as a player in translation termination. Dbp5 interacts genetically with both release factors and the polyadenlyate-binding protein Pab1. A physical interaction was specifically detected with eRF1. Moreover, we show that the helicase activity of Dbp5 is required for efficient stop-codon recognition, and intact Dbp5 is essential for recruitment of eRF3 into termination complexes. Therefore, Dbp5 controls the eRF3-eRF1 interaction and thus eRF3-mediated downstream events.
Real Time Analysis of Antibody‐Antigen Reaction Kinetics

Surface plasmon resonance, i.e. detection of changes in refractive index on a surface, was used in a biosensor to evaluate the dissociation/association rate and affinity constants of human monoclonal IgG and IgM antibodies and Tab fragments. The results showed that an observed difference in affinity constants between intact and fragmented IgG anti‐tetanus antibody was related to approximately 10‐fold differences in dissociation rate constants, since the association rate constants were in the same range, i.e. 2–3×105 (m‐1s‐1). Affinity constants, as determined by conventional solid phase enzyme immunoassays, were substantially higher than the constants produced by the biosensor. Human monoclonal IgM anti‐Tnα antibodies showed, furthermore, one order of magnitude higher association rate constants, as compared with the IgG antibodies, but since the dissociation rate constants were more than ten times higher, the resulting affinity constants of the anti‐carbohydrate IgM antibodies were still somewhat lower than those of the IgG antibodies.
Reconfigurable distributed control of water delivery canals

This work addresses reconfigurable distributed LQG control of multipurpose open water channels, used both for water delivery and transportation. The use of a local control agent structure of the so called local upstream control type ensures that the water level is kept close to a desired level, even in the presence of disturbances caused by water turnout at side offtakes, so as to ensure navigability. Both actuator and sensor faults are addressed. The paper shows how, in the presence of a fault, the controller/sensor network might be reconfigured in order to mitigate its effects. Experimental results in a large scale pilot canal are included to demonstrate the control concepts proposed.
Genomic alterations in human mesothelioma including high resolution mapping of common regions of DNA loss in chromosome arm 6q.

BACKGROUND Molecular genetic analysis of 14 freshly resected human mesotheliomas was used to identify regions in the tumor genomes that display DNA copy number alterations, especially the regions that may harbor tumor suppressor genes. MATERIALS AND METHODS Three methods for molecular analysis were used, comparative genomic hybridization (CGH), loss of heterozygosity (LOH) and a new method, quantitative microsatellite analysis (QuMA). RESULTS The most frequent alteration detected by CGH and LOH was deletion in chromosome 6q, for which QuMA was performed at 30 different loci so as to define the region(s) of common deletion(s). Our data indicates that there are three independent regions of common deletion, one of size 8.4 Mb located at 6q14, a second of size 15.9 Mb at 6q22 and a third of size 12.0 Mb at 6q24. CONCLUSION This suggests that at least 3 tumor suppressor genes mapped to chromosome 6q are commonly involved in the pathogenesis of mesothelioma.
Iterative power allocation for downlink green cognitive radio network

In this paper, the problem of determining the power allocation that maximizes the energy-efficiency of cognitive radio network is investigated as a constrained fractional programming problem (CFPP). The fractional objective is defined in terms of bits per Joule per Hz. The proposed CFPP is a nonlinear non-convex optimization problem. We propose an iterative power algorithm (IPA) that guarantees ε-optimal solution. The convergence of IPA is proved and numerical solutions obtained using simulations are presented.
IPMC actuator-based a movable robotic venus flytrap

Nature is a perfect model for a robot. Besides the insects and underwater animals, some carnivorous plants which are capable of rapid movement, such as mimosa, the venus fly trap, the telegraph plant, sundews and bladderworts, are of great interest for the biomimetic robot design. Carnivorous plants, such as Venus flytrap, can be turned on in a controlled manner to capture prey by using their trigger hairs as detecting sensors. In our previous research, we designed a robotic Venus flytrap by using two ionic polymer metal composite (IPMC) actuators and one proximity sensor. To enlarge its working area in real applications, we improved it by integrating biomimetic walking and rotating motions into the previous version. First, we proposed a conceptual structure of the improved robotic Venus flytrap which consisted of two IPMC lobes, one proximity sensor, and eight IPMC legs. Then, we developed a prototype movable robotic Venus flytrap and evaluated its walking and rotating speeds by using different applied signal voltages. At last, to reduce the gaps between two IPMC lobes, we improved the robotic flytrap by using three IPMC lobes. The experimental results showed a good performance.

Structural basis for tetrapyrrole coordination by uroporphyrinogen decarboxylase

Uroporphyrinogen decarboxylase (URO‐D), an essential enzyme that functions in the heme biosynthetic pathway, catalyzes decarboxylation of all four acetate groups of uroporphyrinogen to form coproporphyrinogen. Here we report crystal structures of URO‐D in complex with the I and III isomer coproporphyrinogen products. Crystallization required use of a novel enzymatic approach to generate the highly oxygen‐sensitive porphyrinogen substrate in situ. The tetrapyrrole product adopts a domed conformation that lies against a collar of conserved hydrophobic residues and allows formation of hydrogen bonding interactions between a carboxylate oxygen atom of the invariant Asp86 residue and the pyrrole NH groups. Structural and biochemical analyses of URO‐D proteins mutated at Asp86 support the conclusion that this residue makes important contributions to binding and likely promotes catalysis by stabilizing a positive charge on a reaction intermediate. The central coordination geometry of Asp86 allows the initial substrates and the various partially decarboxylated intermediates to be bound with equivalent activating interactions, and thereby explains how all four of the substrate acetate groups can be decarboxylated at the same catalytic center.

Effect of thawing time, cooling rate and boron nutrition on freezing point of the primordial shoot in norway spruce buds.

BACKGROUND Effects of cooling rates on bud frost hardiness have been studied but there is little information on bud responses to thawing. Since the cell wall pore size has been found to increase with boron (B) deficiency, B deficiency may affect the supercooling ability of buds in winter. METHODS The effects of duration of thawing time and rate of cooling on bud frost hardiness of Norway spruce (Picea abies) were studied in a B fertilization trial in February 2003 and March 2005. Frost hardiness of apical buds was determined by differential thermal analysis (DTA) and visual scoring of damage. KEY RESULTS In 2003, the freezing point of primordial shoots of buds (T(f)), i.e. the low-temperature exotherm (LTE), was, on average, -39 degrees C when buds were thawed for less than 3 h and the T(f) increased to -21 degrees C after 18 h of thawing. During the first 4 h of thawing, the rate of dehardening was 6 degrees C h(-1). In 2005, buds dehardened linearly from -39 degrees C to -35 degrees C at a rate of 0.7 degrees C h(-1). In 2003, different cooling rates of 1-5 degrees C h(-1) had a minor effect on T(f) but in 2005 with slow cooling rates T(f) decreased. In both samplings, at cooling rates of 2 and 1 degrees C h(-1), T(f) was slightly higher in B-fertilized than in non-fertilized trees. By contrast, at very short thawing times in 2003, T(f) was somewhat lower in B-fertilized trees. CONCLUSIONS There was little evidence of reduced frost hardiness in trees with low B status. This study showed that buds deharden rapidly when exposed to above-freezing temperatures in winter, but if cooled again they reharden more slowly. According to this study, rapid dehardening of buds has to be taken into account in assessments of frost hardiness.
The Phonetics and Phonology of "De²nitive Accent" in Tongan

The so-called de²nitive accent (DA) in Tongan has been analyzed in various ways in the literature: as stress shift from penultimate to ²nal vowel, as simul- taneous stress reduction on a penult and stress addition on an ultima, and as addition of a syllable by repetition of the ²nal vowel. This study investigates each of these analyses empirically in order to establish the phonology of DA in Tongan. Our ²ndings support Melenaite Taumoefolau's proposal that de²nite NPs are formed by repetition of the NP-²nal vowel, and thus a morphological analysis of DA as reduplicative suf²xation. Moreover, our ²ndings substantiate an account of Tongan in which stress is unexceptionally penultimate in a foot, and in which "long vowels" and "diphthongs" are to be considered sequences of two syllables, as suggested by Taumoefolau.
Efficient archiving of documents with protection of their authentic content

A new approach for efficient archiving and content protection of scanned documents, comprising texts and pictures, is presented in this paper. The offered approach presumes to compress the pictures and the texts in different way: the pictures – with lossy coding based on decomposition, called inverse difference pyramid (IDP), and the parts, containing text (graphics) – with lossless coding. For the reliable image content protection is offered new method for digital watermarking based on the IDP decomposition, which permits the insertion of multi-layer watermarks.
Utility of SPECT/CT in preoperative planning for sentinel lymph node biopsy in melanoma and head/neck carcinoma: three illustrative cases.

We present 3 cases in which sentinel lymphoscintigraphy was supplemented with SPECT/CT and aided the surgeon by providing precise information regarding the precise anatomic location and depth of the sentinel lymph nodes (SLN) from the skin surface. The application of SPECT/CT to localization of sentinel lymph nodes is a new addition to the lymphoscintigraphy procedure, which has been greeted enthusiastically by surgeons already accustomed to viewing PET/CT images, and which promises to improve depiction and provide more precise anatomic localization of traditionally difficult situations, including nodes close to or underlying the injection site and within salivary glands as well as in-transit nodes.
Vestibular stimulation by magnetic fields

Individuals working next to strong static magnetic fields occasionally report disorientation and vertigo. With the increasing strength of magnetic fields used for magnetic resonance imaging studies, these reports have become more common. It was recently learned that humans, mice, and zebrafish all demonstrate behaviors consistent with constant peripheral vestibular stimulation while inside a strong, static magnetic field. The proposed mechanism for this effect involves a Lorentz force resulting from the interaction of a strong static magnetic field with naturally occurring ionic currents flowing through the inner ear endolymph into vestibular hair cells. The resulting force within the endolymph is strong enough to displace the lateral semicircular canal cupula, inducing vertigo and the horizontal nystagmus seen in normal mice and in humans. This review explores the evidence for interactions of magnetic fields with the vestibular system.
A New Look at Monogamy

Social monogamy, in which parents cooperate to raise their brood, is relatively common among animals--but true sexual fidelity is hard to find. Recent research has shown that in many species, females once thought to be monogamous bear offspring with different fathers. Even when social bonds are strong, extrapair matings apparently offer evolutionary advantages for both females and males.
Sensitivity enhancement of split ring resonator based liquid sensors

Here, a planar microwave liquid sensor, including an embedded channel in the substrate is reported. The device has been designed to resonate at 5 GHz with a quality factor of 110. A comparison between the proposed structure and the conventional ones with fluidic channel on the surface of the resonator is made to demonstrate the sensitivity enhancement of the proposed design. Our comparison results regarding to sensitivity demonstrates a possibility of up to 400 % improvement for low permittivity materials while the channel is embedded inside the substrate. A very simple implementation process is also proposed.
Monocular vision for robot navigation

The structure and camera pose obtained using multiple view geometry based techniques cannot readily be used for robot localization and mapping. This is due to the fact that the structure and pose obtained relate to the actual environment and motion only up to a transform. In this paper, a method to localize the robot using monocular vision is presented. The assumptions are that the initial pose of the robot is known and that five or more landmarks (true, world points) can be identified. If two or more dissimilar views of at least five non coplanar feature points are initially available, subsequent robot locations with respect to the landmarks in view can be established. The exploration of the environment can then take place incorporating new feature points as the robot moves and successive images are acquired. The feature points which are no longer present in the field of view have to be handled along with the occluded ones. In the presented method, the recovered structure and the knowledge about the intrinsic parameters of the camera are used to obtain the metric structure. Depending on the number of images considered at a time, the structure recovery can be done using the epipolar constraints or using the factorization method. The coordinates of the known landmarks are used to calculate the true 3D world coordinates of the feature points. Current location of the robot is established with respect to these landmarks. The world coordinates of the subsequently observed feature points are obtained using the full camera calibration available following the robot localization. The proposed method avoids cumbersome stereo rig calibration. It naturally uses the new feature information available as the robot moves, for incremental localizations. The performance of the algorithm is verified with simulation and real results.
