SNOC: Streaming Network Node Classification

Many real-world networks are featured with dynamic changes, such as new nodes and edges, and modification of the node content. Because changes are continuously introduced to the network in a streaming fashion, we refer to such dynamic networks as streaming networks. In this paper, we propose a new classification method for streaming networks, namely streaming network node classification (SNOC). For streaming networks, the essential challenge is to properly capture the dynamic changes of the node content and node interactions to support node classification. While streaming networks are dynamically evolving, for a short temporal period, a subset of salient features are essentially tied to the network content and structures, and therefore can be used to characterize the network for classification. To achieve this goal, we propose to carry out streaming network feature selection (SNF) from the network, and use selected features as gauge to classify unlabeled nodes. A Laplacian based quality criterion is proposed to guide the node classification, where the Laplacian matrix is generated based on node labels and structures. Node classification is achieved by finding the class that results in the minimal gauging value with respect to the selected features. By frequently updating the features selected from the network, node classification can quickly adapt to the changes in the network for maximal performance gain. Experiments demonstrate that SNOC is able to capture changes in network structures and node content, and outperforms baseline approaches with significant performance gain.

Monoclonal antibodies provide specific intramolecular markers for the study of epithelial tonofilament organization

The tonofilament-associated protein antigens recognized in epithelial cells by a group of six monoclonal antibodies have been studied by immunofluorescence and gel immunoautoradiography. The monoclonal antibodies were generated against detergent insoluble cytoskeleton extracts from a cultured simple epithelium derived cell line, Ptk1 cells. They show various tissue specificities, and while they all recognize components at the low end of the molecular weight range for intermediate filament proteins, they confirm that single antibody species can react with multiple polypeptides of different molecular weights in the tonofilament complex. The monoclonal antibodies described here demonstrate the presence of a simple epithelium antigenic determinant associated with intermediate filaments that is not detectable in the specialized cells of squamous and keratinizing epithelia but can reappear in such cells after transformation.
Trend in the Age-Adjusted Incidence of Hip Fractures in South Korea: Systematic Review

Background The incidence of hip fractures has been reported to vary geographically, and its trend has also varied widely. However, the trend in the age-adjusted incidence of hip fractures has not been well studied in Korea. After we identified eligible studies presenting multiple age-adjusted incidences of hip fractures in the Korean population in PubMed, we evaluated changes in the absolute number of occurrence and calculated the annual percentage change (APC) of age-adjusted incidences of hip fractures. Methods We have searched PubMed for the original and English-language literature on the incidence of hip fractures in the Korean population published since 2000. The studies presenting multiple age-adjusted incidences of hip fractures were selected. We evaluated the change in the absolute number of hip fractures and calculated the APC of age-adjusted incidences of hip fractures for each study. Results Three eligible articles were identified. The absolute number of hip fractures for both genders increased over time in all three studies although the operational definition of hip fracture differed from one another. The APC of the age-adjusted incidence of hip fractures was positive for women and negative for men. However, the change was not statistically significant in both genders during each study period (2001–2004, 2005–2008, and 2006–2010, respectively). Conclusions The age-adjusted incidence of hip fractures was stable among men and women, while the absolute number of hip fractures increased for both genders in Korea. Further studies with longer study periods on age-adjusted incidences are required to better determine the trend in the incidence of hip fractures in Korea.
Automatic extraction of stochastic lexicalized tree grammars from treebanks

We present a uniform method for the extraction of stochastic lexicalized tree grammars (SLTG) of diﬀerent complexities from existing treebanks as well as from competence-based grammars , which allows us to analyze the relationship of a grammar automatically induced from a treebank wrt. its size, its complexity, and its predictive power on unseen data. Processing of diﬀerent SLTG is performed by a stochastic version of the two-step Early-based parsing strategy introduced in Schabes and Joshi, 1991.
A Price Dynamics in Bandwidth Markets for Point-to-point Connections

We describe a model of a network of N sub-networks (or routers) where M network users making concurrent point-to-point connections by selling and buying router capacity to and from each other. The resources need to be acquired in complete bundles, but there is only one spot market for each router, i.e. no way to place bids on complete bundles. In order to describe the internal dynamics of the market, we model the observed prices by N-dimensional Ito-processes. Modeling using stochastic processes is novel in this context of describing interactions between end-users in a system with shared resources, and allows a standard set of mathematical tools to be applied. The derived models is intended to price contingent claims on network capacity and thus to price complex network services such as, trading resource bundles, pricing quality of service levels, multicast service, etc.
COMPOSITE FERMIONS WITHOUT U(1)'s

In a recent paper [1], one of us suggested that the composite Higgs mechanism [2] could be combined with models in which composite fermions are kept light by unbroken global chiral symmetries [3] to produce realistic models of the strong and electroweak interactions of quarks and leptons. A particularly interesting class of models was discussed in which the global symmetries that require the masslessness of the Higgs doublet and the quarks and leptons are broken only by weak gauge couplings (like SU(2) × U(1)). It was shown that in all such models, while the W and Z and Higgs boson masses are of order go (where g is a typical electroweak gauge coupling and v is the SU(2) X U(1) breaking VEV of the Higgs doublet), the quark and lepton masses are at most of order g2o. Furthermore, a mechanism which leads to a hierarchy of quark and lepton masses (related to powers of gauge couplings) was exhibited. In ref. [ 1], the composite models were studied using the techniques of effective lagrangians [4] and chiral perturbative theory [5],
Resuscitation-promoting factors reveal an occult population of tubercle Bacilli in Sputum.

RATIONALE Resuscitation-promoting factors (Rpfs) are a family of secreted proteins produced by Mycobacterium tuberculosis (Mtb) that stimulate mycobacterial growth. Although mouse infection studies show that they support bacterial survival and disease reactivation, it is currently unknown whether Rpfs influence human infection. We hypothesized that tuberculous sputum might include a population of Rpf-dependent Mtb cells. OBJECTIVES To determine whether Rpf-dependent Mtb cells are present in human sputum and explore the impact of chemotherapy on this population. METHODS In tuberculous sputum samples we compared the number of cells detected by conventional agar colony-forming assay with that determined by limiting dilution, most-probable number assay in the presence or absence of Rpf preparations. MEASUREMENTS AND MAIN RESULTS In 20 of 25 prechemotherapy samples from separate patients, 80-99.99% of the cells demonstrated by cultivation could be detected only with Rpf stimulation. Mtb cells with this phenotype were not generated on specimen storage or by inoculating sputum samples with a selection of clinical isolates; moreover, Rpf dependency was lost after primary isolation. During chemotherapy, the proportion of Rpf-dependent cells was found to increase relative to the surviving colony-forming population. CONCLUSIONS Smear-positive sputum samples are dominated by a population of Mtb cells that can be grown only in the presence of Rpfs. These intriguing proteins are therefore relevant to human infection. The Rpf-dependent population is invisible to conventional culture and is progressively enhanced in relative terms during chemotherapy, indicating a form of phenotypic resistance that may be significant for both chemotherapy and transmission.
Bmc Medical Informatics and Decision Making an Adaptive Prediction and Detection Algorithm for Multistream Syndromic Surveillance

Background: Surveillance of Over-the-Counter pharmaceutical (OTC) sales as a potential early indicator of developing public health conditions, in particular in cases of interest to biosurvellance, has been suggested in the literature. This paper is a continuation of a previous study in which we formulated the problem of estimating clinical data from OTC sales in terms of optimal LMS linear and Finite Impulse Response (FIR) filters. In this paper we extend our results to predict clinical data multiple steps ahead using OTC sales as well as the clinical data itself.
Characterizing Sufficient Expertise for Learning Systems Validation

There is an obvious necessity to validate resp. verify complex systems. If human experts are involved in the implementation of any validation scenario, there arises the problem of the experts’ competence. As a case study, the problem of expertise for systems validation is investigated in the area of learning systems validation. It turns out that certain humaat expertise sufficient to accomplish certain validation tasks is substantially non-recursive. Consequently, there is no way to replace humans by computer programs for those validation tasks.
Hydroids (Cnidaria, Hydrozoa) from Shallow-Water Environments Along the Caribbean Coast of Panama

—Hydroids were examined in three different collections of specimens, acquired in 1969, 2002, and 2004, from the Caribbean coast of Panama. Eighteen stations were sampled in the Bocas del Toro area, western Panama. Nine others were situated in Colon and vicinity, and a single station was made at Portobelo in the east. Seventy-nine species were identified overall, including 28 anthoathecates, 49 leptothecates, and two actinulids. Included among the anthoathecates were the hydrocorals Millepora alcicornis, M. complanata, M. squarrosa, and Stylaster roseus. The six most frequently encountered species in the collections were Turritopsis nutricula, Nemalecium lighti, Halopteris alternata, Millepora alcicornis, Antennella secundaria, and Dynamena disticha. Records of each species from localities elsewhere in the Caribbean region are summarized. Four species, Ectopleura mayeri, Sagamihydra dyssymetra, Halecium lightbourni, and Tridentata vervoorti, are reported from the Caribbean Sea for the first time.
Age-dependent response of the rat testes to di(2-ethylhexyl) phthalate.

Spermatogenesis starts soon after birth in the Sprague-Dawley rat but is not fully established until about 56 days of age. When high oral doses of the plasticizer di(2-ethylhexyl) phthalate (DEHP) were given to rats of different ages, testicular damage was observed in immature but not in mature animals. Plasma concentration and urinary excretion data suggested that the gastrointestinal absorption of the DEHP-derived metabolite mono(2-ethylhexyl) phthalate was higher in young animals. Young rats were not more susceptible than older for repeated intravenous infusions of DEHP. It is suggested that the age-related difference observed in testicular response after oral administration of DEHP may be due to pharmacokinetic rather than tissue sensitivity differences. It is concluded that in assessing risks of testicular injuries in children exposed to DEHP, additional studies are required using species in which testicular development is more similar to that of humans.

A CMOS 4.35-mW +22-dBm IIP3 Continuously Tunable Channel Select Filter for WLAN/WiMAX Receivers

A low-power high linearity CMOS Gm-C channel select filter for WLAN/WiMAX receivers in 90-nm CMOS technology is presented. To reduce power consumption a biquad cell with simple architecture is used. A simple but efficient technique is also proposed to improve the linearity of the filter without increasing its power consumption. Coarse and fine tuning techniques are used to tune the cutoff frequency of the sixth-order Butterworth low-pass filter from 8.1 MHz to 13.5 MHz suitable for WLAN and WiMAX applications. The measurement results show an in-band IIP3 of + 22 dBm, an HD3 better than - 40 dB at 470 mVP input signal amplitude, and an input referred noise of 75 nV/√Hz at a power consumption of 4.35 mW from a 1-V supply. The differential filter occupies a chip area of 0.239 mm2 excluding pads.
The nominative technique: a new method of estimating heroin prevalence.

Over the years, nominative estimates of heroin prevalence have been consistently higher than self-reports of heroin use. During this time, nominative data have generally followed mainstream patterns of drug use: nominative estimates for young adults and for males are higher than nominative estimates for older persons, youth, and females; moreover, the recent downward trends in drug use have been replicated by the nominative heroin data. Thus, the overall picture presented by the nominative data--similar patterns but higher levels of prevalence--seems to support the validity of the new approach. Nevertheless, considerable caution should be exercised in interpreting nominative data. This is chiefly because a substantial minority of nominators cannot report the number of other close friends of the heroin user who also "know. " While missing data has been handled by a conservative imputation rule, the fact that so many persons are unable to provide an answer to this key question casts doubt on the accuracy of the answers that were given. In fact, the nominative approach might tend to produce over-estimates, because of the potential for undercounts of the numbers of others who "know. " Additional tests of validity should be performed, such as application of the nominative approach to nonsensitive behaviors or minimally sensitive behaviors, such as marijuana use or perhaps cocaine use. Certainly, the overall validity of the nominative heroin data would be supported if in future surveys new nominative heroin estimates for relatively unstigmatized forms of drug use proved to be similar to self-reported levels of use, thus pointing to the unique difference in estimates that might be observed for heroin. Finally, in interpreting the heroin estimates presented here, it should be remembered that both the nominative and self-report estimates refer to heroin use in the household population of the United States. Thus, many heroin addicts and other users who reside in various unconventional living arrangements would not be included in the counts presented here. Among the excluded groups are transients residing in rooming houses or "crashing" in the home of one "friend" after another or who are incarcerated in jails or confined to residential drug treatment centers. This is a caution for interpreting the estimates presented in this paper, not a criticism of the nominative technique itself. (ABSTRACT TRUNCATED AT 400 WORDS)
A survey of available tools and web servers for analysis of protein-protein interactions and interfaces

The unanimous agreement that cellular processes are (largely) governed by interactions between proteins has led to enormous community efforts culminating in overwhelming information relating to these proteins; to the regulation of their interactions, to the way in which they interact and to the function which is determined by these interactions. These data have been organized in databases and servers. However, to make these really useful, it is essential not only to be aware of these, but in particular to have a working knowledge of which tools to use for a given problem; what are the tool advantages and drawbacks; and no less important how to combine these for a particular goal since usually it is not one tool, but some combination of tool-modules that is needed. This is the goal of this review.

Parasitoids of Queensland Fruit Fly Bactrocera tryoni in Australia and Prospects for Improved Biological Control

This review draws together available information on the biology, methods for study, and culturing of hymenopteran parasitoids of the Queensland fruit fly, Bactrocera tryoni, and assesses prospects for improving biological control of this serious pest. Augmentative release of the native and naturalised Australian parasitoids, especially the braconid Diachasmimorpha tryoni, may result in better management of B. tryoni in some parts of Australia. Mass releases are an especially attractive option for areas of inland eastern Australia around the Fruit Fly Exclusion Zone that produces B. tryoni-free fruits for export. Diachasmimorpha tryoni has been successful in other locations such as Hawaii for the biological control of other fruit fly species. Biological control could contribute to local eradication of isolated outbreaks and more general suppression and/or eradication of the B. tryoni population in endemic areas. Combining biological control with the use of sterile insect technique offers scope for synergy because the former is most effective at high pest densities and the latter most economical when the pest becomes scarce. Recommendations are made on methods for culturing and study of four B. tryoni parasitoids present in Australia along with research priorities for optimising augmentative biological control of B. tryoni.
Intraguild interactions between five congeneric species of Thaparocleidus (Monogenoidea) from the freshwater shark Wallago attu, Lucknow, India

Abstract The fish host (Wallago attu) and monogenoid parasite (Thaparocleidus sp.) have been recorded during 2 years (2011 and 2012) to investigate intra/interspecific interactions among query species (T. sudhakari (Gusev, 1976) Lim, 1996; T. indicus (Kulkarni, 1969) Lim, 1996; T. gomtius (Jain, 1952) Lim, 1996; T. yogendraii Agrawal, 1981 and T. wallagonius Jain, 1952) in the light of parasitic worm burden, morphological and molecular data. Each species is highly host specific (oioxenous), with a specialized functional niche. Being niche specialists, they exhibit niche overlapping along with co-existence due to reproductive barrier. Furthermore, a molecular marker, affirming clear-cut genetic variation in spite of structural entities, provides evidence for infra-speciation as well as co-speciation.
Sorting and hardware assisted rendering for volume visualization

We present some techniques for volume rendering unstructured data. Interpolation between vertex colors and opacities is performed using hardware assisted texture mapping, and color is integrated for use with a volume rendering system. We also present an O(n{sup 2}) method for sorting n arbitrarily shaped convex polyhedra prior to visualization. It generalizes the Newell, Newell and Sancha sort for polygons to 3-D volume elements.
RESISTANCE OF THE MOUSE'S INTESTINAL TRACT TO EXPERIMENTAL SALMONELLA INFECTION

Multiplication of Salmonella enteritidis was inhibited in vitro by buffered suspensions of fecal material freshly removed from the large intestine of normal mice. Most effective was material obtained from cecum and transverse colon. Inhibitory activity was not impaired by sterilization by heat or filtration. From such materials were isolated acetic and butyric acids in concentrations which inhibited Salmonella in vitro. The degree of inhibitory activity of suspensions of colon content and of mixtures of the two fatty acids was conditioned by pH and favored by anaerobiosis. Effective inhibition occurred at or slightly below the pH of colon content of most normal mice as determined in situ by direct measurement. Acetic and butyric acids were isolated from anaerobic cultures of several strains of Bacteroides previously demonstrated to be one of the most numerous inhabitants of the large intestine of the normal mouse.
Zero Bound on Interest Rates and Optimal Monetary Policy

This paper considers the consequences for monetary policy of the zero floor for nominal interest rates. The zero bound can be a significant constraint on the ability of a central bank to combat deflation. The paper shows, in the context of an intertemporal equilibrium model, that open-market operations, even of "unconventional" types, are ineffective if future policy is expected to be purely forward looking. However, a credible commitment to the right sort of history-dependent policy can largely mitigate the distortions created by the zero bound. In the model, optimal policy involves a commitment to adjust interest rates so as to achieve a time-varying price-level target, when this is consistent with the zero bound. The paper also discusses ways in which other central bank actions, although irrelevant apart from their effects on expectations, may help to make a central bank's commitment to its target more credible.
