Indexing fingerprints using minutiae quadruplets

The computational complexity of matching an input fingerprint against every entry in a large-scale fingerprint database can be prohibitive. In fingerprint indexing, a small set of candidate fingerprints is selected from the database and only images in this set are compared against the input probe fingerprint thereby avoiding an exhaustive matching process. In this paper, a new structure named “minutiae quadruplet” is proposed for indexing fingerprints and is used in combination with a clustering technique to filter a fingerprint database. The proposed indexing algorithm is evaluated on all datasets in the Fingerprint Verification Competition (FVC) 2000, 2002 and 2004 databases. The high hit rates achieved at low penetration rates suggest that the proposed algorithm is beneficial for indexing. Indeed, it was observed that for 50% of the fingerprints, in most of the datasets, the penetration rate was less than 5.5% at a 100% hit rate. The robust performance across different databases suggests that the indexing algorithm can be adapted for use in large-scale databases.
Scopes Describe Frames: A Uniform Model for Memory Layout in Dynamic Semantics

Semantic specifications do not make a systematic connection between the names and scopes in the static structure of a program and memory layout, and access during its execution. In this paper, we introduce a systematic approach to the alignment of names in static semantics and memory in dynamic semantics, building on the scope graph framework for name resolution. We develop a uniform memory model consisting of frames that instantiate the scopes in the scope graph of a program. This provides a language-independent correspondence between static scopes and run-time memory layout, and between static resolution paths and run-time memory access paths. The approach scales to a range of binding features, supports straightforward type soundness proofs, and provides the basis for a language-independent specification of sound reachability-based garbage collection.
A limit on the diffuse gamma-rays measured with KASCADE-Grande

Using data measured by the KASCADE-Grande air shower array, an upper limit to the flux of ultra-high energy gamma-rays in the primary cosmic-ray flux is determined. KASCADE-Grande measures the electromagnetic and muonic components for individual air showers in the energy range from 10 PeV up to 1 EeV. The analysis is performed by selecting air showers with low muon contents. A preliminary result on the 90% C.L. upper limit to the relative intensity of gamma-ray with respect to cosmic ray primaries is presented and compared with limits reported by other measurements.
Colloids for the Initial Management of Severe Sepsis and Septic Shock in Pediatric Patients: A Systematic Review

Aim The goal of this study was to perform a systematic review of the literature assessing the use of colloids for the initial treatment of severe sepsis and septic shock in pediatric patients. Design The PICO [Patient, Intervention, Comparison, Outcome] method was used for the selection of studies, and the Cochrane Bias Tool was used to analyze the quality of the selected studies. Data Search Relevant studies were sought using the following databases: EMBASE (1980 to March 2014), PubMed (1970 to March 2014), Cochrane (1980 to March 2014), Web of Science, and Scopus. Searches used the following key words: isotonic solution, crystalloid, saline solution, colloid, resuscitation, fluid therapy, sepsis and septic shock, starch, and gelatin. The filters children and clinical trial were used when possible. Review Method Study selection was performed by 1 examiner. The selected articles were analyzed by 2 examiners who validated the articles according to the Cochrane Bias Tool. Discrepancies were resolved by consensus or by a third examiner. Result A total of 110 articles were selected based on the key words. Of these, 99 were excluded because they assessed postoperative follow-up, burn cases, cardiac surgery, or nutritional therapy or were review articles, guidelines, or editorials. One study was included after an analysis of previous reviews. A total of 12 articles were selected for analysis because they were reports of clinical trials conducted with prospective cohorts and they analyzed the use of crystalloids and colloids or colloids only in the initial treatment of severe sepsis or septic shock in children and adolescents. The total number of patients was 4375, and they ranged in age from 2 months to 15 years, with most patients between 5 and 15 years. Five studies assessed patients diagnosed with malaria, 5 assessed patients with dengue shock syndrome, 1 studied febrile diseases, and 1 examined the progression of patients with septic shock caused by various causes. Conclusions The studies analyzed did not find evidence to suggest that the use of colloids is superior to crystalloids. In some studies, the fluid volume needed to achieve initial stabilization was smaller in the group given colloids. Crystalloids are the preferred therapeutic option because of their effectiveness, low cost, and wide availability. Colloids may be the first choice in cases of malaria when the central nervous system is affected.
Estrogen's bone-protective effects may involve differential IL-1 receptor regulation in human osteoclast-like cells.

Declining estrogen levels during the first postmenopausal decade lead to rapid bone loss and increased fracture risk that can be reversed by estrogen replacement therapy. The bone-protective effects of estrogen may involve suppression of inflammatory cytokines that promote osteoclastogenesis and bone resorption, such as IL-1, TNF-alpha, and IL-6. We investigated whether estrogen modulates IL-1 actions on human osteoclasts (OCs) and other bone cell types. Isolated human OCs and primary bone marrow-derived OC-like cells expressed both the signaling (IL-1RI) and decoy (IL-1RII) IL-1 receptors, whereas only IL-1RI was detected in osteoblasts. IL-1RII/IL-1RI mRNA ratios and release of soluble IL-1RII (sIL-1RII) were lower in OC-like cells derived from women in the late postmenopausal period compared with younger women, but were unrelated to male donor age, suggesting that estrogen might play a role in regulating IL-1 receptor levels in vivo. Estrogen directly reduced in vitro OC-like cell IL-1RI mRNA levels while increasing IL-1RII mRNA levels and sIL-1RII release. These estrogenic events were associated with inhibited IL-1-mediated cytokine (IL-8) mRNA induction and cell survival, i.e., increased apoptosis. In contrast, estrogen did not alter IL-1R levels or IL-1 responsiveness in primary human osteoblasts or bone marrow stromal cells. We conclude that one novel mechanism by which estrogen exerts bone-protective effects may include a selective modulation of IL-1R isoform levels in OC or OC-like cells, thereby reducing their IL-1 responsiveness and cell survival. Conversely, this restraint on IL-1 actions may be lost as estrogen levels decline in aging women, contributing to an enhanced OC-mediated postmenopausal bone loss.
GABAergic Depolarization of the Axon Initial Segment in Cortical Principal Neurons Is Caused by the Na–K–2Cl Cotransporter NKCC1

GABAergic terminals of axo-axonic cells (AACs) are exclusively located on the axon initial segment (AIS) of cortical principal neurons, and they are generally thought to exert a powerful inhibitory action. However, recent work (Szabadics et al., 2006) indicates that this input from AACs can be depolarizing and even excitatory. Here, we used local photolysis of caged GABA to measure reversal potentials (E GABA) of GABAA receptor-mediated currents and to estimate the local chloride concentration in the AIS compared with other cellular compartments in dentate granule cells and neocortical pyramidal neurons. We found a robust axo-somato-dendritic gradient in which the E GABA values from the AIS to the soma and dendrites become progressively more negative. Data from NKCC1 −/− and bumetanide-exposed neurons indicated that the depolarizing E GABA at the AIS is set by chloride uptake mediated by the Na–K–2Cl cotransporter NKCC1. Our findings demonstrate that spatially distinct interneuronal inputs can induce postsynaptic voltage responses with different amplitudes and polarities as governed by the subcellular distributions of plasmalemmal chloride transporters.
Syntactic Analysis of the Tunisian Arabic

In this paper, we study the problem of syntactic analysis of Dialectal Arabic (DA). Actually, corpora are considered as an important resource for the automatic processing of languages. Thus, we propose a method of creating a treebank for the Tunisian Arabic (TA) “Tunisian Treebank” in order to adapt an Arabic parser to treat the TA which is considered as a variant of the Arabic language.
Association between Nutrient Intake and Obesity in Type 2 Diabetic Patients from the Korean National Diabetes Program: A Cross-Sectional Study

The aim of the study was to assess the association between usual dietary nutrient intake and obesity in Korean type 2 diabetic patients. We examined 2,832 type 2 diabetic patients from the Korean National Diabetes Program cohort who completed dietary assessment and clinical evaluation in this cross-sectional study. In men, higher dietary fiber intake was associated with a lower odds of being obese (Ptrend = 0.003) and in women, higher protein intake was associated with a lower odds of being obese (Ptrend = 0.03) after adjustment for age, diabetes duration, HbA1c, alcohol drinking, income, education level, and calorie intake. In men, higher fiber intake was associated with lower odds of obesity after further adjustment for diastolic blood pressure, physical activity, and possible confounding nutritional intake and medication. The multivariable adjusted odds ratio for the highest quintile of fiber intake was 0.37 (Ptrend < 0.001). In women, protein intake was not associated with obesity after further adjustment. In conclusion, higher intake of dietary fiber is associated with lower odds of being obese in type 2 diabetic men, suggesting a role for dietary fiber in the management and prevention of obesity in type 2 diabetes (ClinicalTrials.gov: NCT 01212198).
CONSERVATIVE PARALLEL SIMULATION OF A MESSAGE-PASSING NETWORK : A PERFORMANCE STUDY

In this paper we evaluate the behaviour of a conservative parallel simulator implemented on a network of Transputers, when used to simulate an interconnection network proposed as the communication mechanism of a multicomputer. After a set of experiments, we conclude that some parameters of the model ( size, load, message length ) have a great impact on the achieved performance. Additionally, some parameters of the simulatior itself may allow the user to run the simulation faster, namely grain size of the processes and ability to exploit the lookahead of the model.
The Parental Bonding Instrument: a measure of perceived or actual parental behavior?

In the investigation of the relationship between childhood adversity and adult psychopathology. scales that require retrospective reports of parental style are often employed. Controversy exists as to whether these scales reflect the actual behavior of the parents concerned or reflect the perceptions of the child. One such scale, the Parental Bonding Instrument, was completed by a volunteer sample of 672 twins. For females, agreement between twins was generally high and a shared environment model fitted all scales except maternal care. This is consistent with the view that the ratings reflect the behavior of the parents. Agreement between male twins was substantially lower and well‐fitting models did not include a shared environment component. It is argued that the scales may be affected by competition between twins or comparisons made by the respondent with his or her co‐twin.

Rhizobium lipopolysaccharide modulates infection thread development in white clover root hairs

The interaction between Rhizobium lipopolysaccharide (LPS) and white clover roots was examined. The Limulus lysate assay indicated that Rhizobium leguminosarum bv. trifolii (hereafter called R. trifolii) released LPS into the external root environment of slide cultures. Immunofluorescence and immunoelectron microscopy showed that purified LPS from R. trifolii 0403 bound rapidly to root hair tips and infiltrated across the root hair wall. Infection thread formation in root hairs was promoted by preinoculation treatment of roots with R. trifolii LPS at a low dose (up to 5 micrograms per plant) but inhibited at a higher dose. This biological activity of LPS was restricted to the region of the root present at the time of exposure to LPS, higher with LPS from cells in the early stationary phase than in the mid-exponential phase, incubation time dependent, incapable of reversing inhibition of infection by NO3- or NH4+, and conserved among serologically distinct LPSs from several wild-type R. trifolii strains (0403, 2S-2, and ANU843). In contrast, infections were not increased by preinoculation treatment of roots with LPSs from R. leguminosarum bv. viciae strain 300, R. meliloti 102F28, or members of the family Enterobacteriaceae. Most infection threads developed successfully in root hairs pretreated with R. trifolii LPS, whereas many infections aborted near their origins and accumulated brown deposits if pretreated with LPS from R. meliloti 102F28. LPS from R. leguminosarum 300 also caused most infection threads to abort. Other specific responses of root hairs to infection-stimulating LPS from R. trifolii included acceleration of cytoplasmic streaming and production of novel proteins. Combined gas chromatography-mass spectroscopy and proton nuclear magnetic resonance analyses indicated that biologically active LPS from R. trifolii 0403 in the early stationary phase had less fucose but more 2-O-methylfucose, quinovosamine, 3,6-dideoxy-3-(methylamino)galactose, and noncarbohydrate substituents (O-methyl, N-methyl, and acetyl groups) on glycosyl components than did inactive LPS in the mid-exponential phase. We conclude that LPS-root hair interactions trigger metabolic events that have a significant impact on successful development of infection threads in this Rhizobium-legume symbiosis.
Influence of the topology on the power flux of the Italian high-voltage electrical network

A model of the Italian 380 kV electrical transmission network has been analyzed under the topological and the functional viewpoints. The DC power flow model used to evaluate the power flux has been solved on the basis of input conditions (injected power - extracted power, line's reactances and the maximum flux capacity of each line) taken from real data. The vulnerability of the network under load conditions has been estimated by evaluating the power flux redistribution along the lines subsequent to line's removal. When the perturbed network cannot sustain a given input--output demand, the maximum power sustainable by the network has been evaluated to optimize the \texttt{Quality of Service}, defined as the difference between the expected and the effective dispatched power. The functional relevance of the different lines of the network has been classified according to the amount of power that the network must reduce, to keep alive, upon their removal. Results show that topological and functional relevances are related to different lines; lines having a strong topological relevance may have a bare relevance in the flow distribution and thus their removal does not affect the functioning of the network.
Accessibility and Viability: A Complex Adaptive Systems Approach to a Wicked Problem for the Local Food Movement

There is a tension between enhancing vulnerable people's access to local nutritious food and ensuring viable incomes for local farmers. This tension arises as a result of interactions and processes scaling outward to the broad level of economic and political ideologies (Ikerd, 2005; 2012). We suggest that by conceiving of this tension as a wicked problem and employing complex adaptive systems theory, we create space in which community members are empowered to share existing knowledge and develop new knowledge as they innovate potential solutions and discuss constructive change. We introduce this space as the beginnings of a dialogue-driven, shared journey through four features of the back loop of the adaptive cycle. Drawing on this theoretical foundation as well as Block's (2009) structure for creating a community of belonging, we hosted two one-half-day-long events for 90 community members, including farmers, food-insecure people, government representatives, and public agencies. This bottom-up, emergent approach to developing new system patterns may ultimately transform the domain of the problem and present viable alternative futures, which then may be adapted to the local reality and enhance community well being.
Quantification the Effect of Ageing on Characteristics of the Photoplethysmogram Using an Optimized Windkessel Model

Background: With increasing age, some changes appeared in specifications of vessels which including dimensions and elasticity in theirs. The changes in parameters such as resistance, inertance and compliance vessels appear and eventually changes in the environmental pulse releases are in circulation. These changes clearly appear in specification of photoplethysmogram particularly in the size and position signals second peak is observed. Aim and scope: The aim of study was to Circulatory system modeling using windkessel electrical model for evalution blood flow and Its matching with the photoplethysmogram’s signal for investigate the reasons for changes of Characteristics of the Photoplethysmogram. The first purpose of this paper is to examine the age-related parameters in the Photoplethysmogram’s signal and finally the diagnosis of cardiovascular disease using the model and photoplethysmogram’s signal. Methods: In this study we followed some of these effects to the circulatory system by using the windkessel electrical model. The algorithm in this project appeared by optimization with the matrix coefficients of state space windkessel electrical model. Optimize of the coefficients matching with the output of the model and the photoplethysmogram’s signal. Photoplethysmogram’s signals from 50 healthy subjects with the age range of 20 to 50 years, shows that outputs the model and photoplethysmogram’s signal in terms of error rate and cross-correlation algorithm in a fully automate, was consistent. Wavelength of the Photoplethysmogram’s signals were 950 nm and The sampling rate was set at 50 Hz. Results: Simulation results show that aging reduces the signal amplitude and delay of the second peak occurs. These changes were seen as reduce the rate of compliance and increase the rate of resistance and inertance windkessel electrical model of circulation. Conclusion: The high accuracy of the results led to being able to identify the age range and some cardiac arrhythmias in individuals. All the simulations were done in matlab software environment.
Rigor crossbridges are double-headed in fast muscle from crayfish

The structure of rigor crossbridges was examined by comparing rigor crossbridges in fast muscle fibers from glycerol-extracted abdominal flexor muscle of crayfish with those in "natively decorated" thin filaments from the same muscle. Natively decorated thin filaments were obtained by dissociating the backbone of the myosin filaments of rigor myofibrils in 0.6 M KCl. Intact fibers were freeze-fractured, deep- etched, and rotary shadowed; isolated filaments were either negatively stained or freeze dried and rotary shadowed. The crossbridges on the natively decorated actin maintain the original spacing and the disposition in chevrons and double chevrons for several hours, indicating that no rearrangement of the actomyosin interactions occurs. Thus the crossbridges of the natively decorated filaments were formed within the geometrical constraints of the intact myofibril. The majority of crossbridges in the intact muscle have a triangular shape indicative of double-headed crossbridge. The triangular shape is maintained in the isolated filaments and negative staining resolves two heads in a single crossbridge. In the isolated filaments, crossbridges are attached at uniform acute angles. Unlike those in insect flight muscle (Taylor et al., 1984), lead and rear elements of the double chevron may be both double-headed. Deep-etched images reveal a twisted arrangement of subfilaments in the backbone of the thick filament.
A novel coding scheme to implement signature based IDS in IP based Sensor Networks

In signature based IDS (Intrusion Detection Systems), if incoming packet header matches a certain set of rules, its payload is scrutinized against a set of known patterns (also called signatures). As the number of patterns could range up to thousands, pattern matching consumes not only the storage but also the most of the CPU cycles to execute the complex pattern matching algorithms. Therefore, so far there is no signature based IDS which can work on resource constraint sensor nodes. This paper presents a dynamic coding mechanism, which helps in implementing a distributed signature based IDS (Intrusion Detection System) in IP-USN (IP based Ubiquitous Sensor Networks). The proposed scheme also allows building of lightweight IDS in terms of storage, messaging and energy consumption, which make it appropriate for resource constrained sensor devices.
