Fractional stochastic resonance of multi-frequency weak periodic signals in alpha-stable noisy environment

This paper studies the stochastic resonance (SR) phenomenon generated by the multi-frequency weak periodic signals on the bistable fractional system in α - stable noisy environment. The influence to the output signal are analyzed by the structural parameters a, b of bistable system, the intensity D of α - stable noise as well as the fractional order p individually while the other parameters kept unchanged. The numerical simulation results show that the fractional order p can enhance the SR by analyzing the power spectrum of output signal. The characteristic index Average Signal-to-noise ratio (SNR) Gain is used to reflect the influence to the SR by changing the structural parameters a, b of bistable system and the intensity D of α - stable noise. Both curves are non-monotonic when one of the parameters is changed, it increases then decreases.
Anakinra, a Recombinant Human Interleukin-1 Receptor Antagonist, Inhibits Apoptosis in Experimental Acute Myocardial Infarction

Background— Experimental interleukin-1 receptor antagonist gene overexpression has shown that interleukin-1 receptor antagonist is cardioprotective during global cardiac ischemia. The aim of the present study was to test the impact of an exogenous recombinant human interleukin-1 receptor antagonist (anakinra) in experimental acute myocardial infarction. Methods and Results— Two animal studies were conducted: one of immediate anakinra administration during ischemia in the mouse and one of delayed anakinra administration 24 hours after ischemia in the rat. Seventy-eight Institute of Cancer Research mice and 20 Wistar rats underwent surgical coronary artery ligation (or sham operation) and were treated with either anakinra 1 mg/kg or NaCl 0.9% (saline). Treatment was administered during surgery and then daily for 6 doses in the mice and starting on day 2 daily for 5 doses in the rats. Twenty-eight mice underwent infarct size assessment 24 hours after surgery, 6 saline-treated mice and 22 mice treated with increasing doses of anakinra (1 mg/kg [n=6], 10 mg/kg [n=6], and 100 mg/kg [n=10]); 6 mice were euthanized at 7 days for protein expression analysis. The remaining animals underwent transthoracic echocardiography before surgery and 7 days later just before death. Cardiomyocyte apoptosis was measured in the peri-infarct regions. The antiapoptotic effect of anakinra was tested in a primary rat cardiomyocyte culture during simulated ischemia and in vitro on caspase-1 and -9 activities. At 7 days, 15 of the 16 mice (94%) treated with anakinra were alive versus 11 of the 20 mice (55%) treated with saline (P=0.013). No differences in infarct size at 24 hours compared with saline were observed with the 1- and 10-mg/kg doses, whereas a 13% reduction in infarct size was found with the 100-mg/kg dose (P=0.015). Treatment with anakinra was associated with a significant reduction in cardiomyocyte apoptosis in both the immediate and delayed treatment groups (3.1±0.2% versus 0.5±0.3% [P<0.001] and 4.2±0.4% versus 1.1±0.2% [P<0.001], respectively). Compared with saline-treated animals, anakinra-treated mice and rats showed signs of more favorable ventricular remodeling. In vitro, anakinra significantly prevented apoptosis induced by simulated ischemia and inhibited caspase-1 and -9 activities. Conclusions— Administration of anakinra within 24 hours of acute myocardial infarction significantly ameliorates the remodeling process by inhibiting cardiomyocyte apoptosis in 2 different experimental animal models of AMI. This may open the door for using anakinra to prevent postischemic cardiac remodeling and heart failure.
Far-Field Optical Hyperlens Magnifying Sub-Diffraction-Limited Objects

The diffraction limit of light, which is causd by the loss of evanescent waves in the far field that carry high spatial frequency information, limits the resolution of optical lenses to the order of the wavelength of light. We report experimental demonstration of the optical hyperlens for sub-diffraction-limited imaging in the far field. The device magnifies subwavelength objects by transforming the scattered evanescent waves into propagating waves in an anisotropic medium and projects the high-resolution image at far field. The optical hyperlens opens up possibilities in applications such as real-time biomolecular imaging and nanolithography.
KADCHIVE : Distributed Personal Storage

KadChive is an approach to enable distributed storage of personal files with high “durability” and to provide “fairness” to users using an “incentive-based” scheme. This system runs on top of a Kademlia peer to peer network. KadChive creates replicas of personal files and places these files amongst specific peers in the network for retrieval at a later date. The purpose of this is to enhance the availability and reliability of files. Because KadChive is built on top of a Kademlia based DHT, it can easily scale to millions of users. In the following report we will discuss an overview of our system design and implementation. We will then give an analysis of various aspects of our system and a list of future work.
Traffic Simulation in Urban Networks Using Stochastic Cell Transmission Model

The stochastic cell transmission model (SCTM) is a macroscopic traffic simulation model of high accuracy. One of its advantages is that it can represent the uncertainty of the traffic states and the changing travel demand and supply conditions. However, it has been applied to freeways and simple networks having only one origin‐destination pair. In this article, we propose a modified stochastic cell transmission model (M‐SCTM) that applies the conventional SCTM to urban networks. In M‐SCTM, we introduce vehicle agents as well as their route choice behavior on an urban network, which is more applicable to complex urban networks. Additionally, M‐SCTM was applied to networks in which the turning ratio is not priorly set through a route search algorithm. The results show that M‐SCTM can conduct simulations with as much accuracy as SCTM. Furthermore, we verified the appropriate reproducibility of the simulations based on M‐SCTM and compared the estimated value and the measured value in terms of the travel time of each vehicle.
Design and Analysis of an XCP-TCP Gateway

The explicit control protocol (XCP), which has many desired properties such as short queuing delay, high utilization and so on, is considered promising for future high bandwidth-delay product (BDP) networks. However, the congestion control mechanism of XCP Is quite different from that of TCP, and as a result, XCP cannot coexist well with TCP. In this paper, we propose a scheme for Incremental deployment of XCP, In which XCP-TCP gateways seamlessly interconnect the XCP and TCP domains. The XCP-TCP gateway maps the congestion control functions between XCP and TCP. Our analysis and simulations show that: 1) TCP-XCP-like flows can coexist well with XCP; 2) TCP-XCP-llke flows have much better RTT fairness than TCP.
Bryozoan carbonates through time and space

The calcareous skeletons of modern bryozoans are major contributors to sediments only outside the tropics, and many temperate limestones are dominated by bryozoans, often in conjunction with mollusks in the so-called “bryomol” grain association. Can the presence of rock-forming abundances of bryozoans be used to recognize nontropical sediments in the geologic past? We have addressed this question by assembling a database of 176 Ordovician-Pleistocene bryozoan-rich deposits and plotting them on paleogeographical maps to obtain their latitudes of formation. The results reveal a striking difference between post-Paleozoic and Paleozoic latitudinal distributions. Whereas the great majority (94%) of post-Paleozoic bryozoan-rich deposits formed outside the tropics, Paleozoic bryozoan-rich deposits have a more variable latitudinal distribution, most (68%) having formed within the tropics. The presence of rock-forming abundances of bryozoans in Paleozoic sediments should not, therefore, be used to infer nontropical carbonate deposition. The change in latitudinal distribution between the Paleozoic and post-Paleozoic corresponds with a major taxonomic turnover in bryozoan faunas. Biotic interactions, especially with predators, may have led to the exclusion of sediment-producing bryozoans from the post-Paleozoic tropics. These evolutionary changes have had a more profound effect on carbonate platforms than has been previously appreciated.

Logsonomy: A Search Engine Folksonomy

In social bookmarking systems users describe bookmarks by keywords called tags. The structure behind these social systems, called folksonomies, can be viewed as a tripartite hypergraph of user, tag and resource nodes. This underlying network shows specific structural properties that explain its growth and the possibility of serendipitous exploration. Search engines filter the vast information of the web. Queries describe a user's information need. In response to the displayed results of the search engine, users click on the links of the result page as they expect the answer to be of relevance. The clickdata can be represented as a folksonomy in which queries are descriptions of clicked URLs. This poster analyzes the topological characteristics of the resulting tripartite hypergraph of queries, users and bookmarks of two query logs and compares it two a snapshot of the folksonomy del.icio. us.
Long-Lived Plasma Cells in Autoimmunity: Lessons from B-Cell Depleting Therapy

A large number of auto-immune diseases are treated with rituximab, an antibody against CD20 that depletes most of the B-cells in the organism. The response to this treatment depends largely on the disease and the type of lymphoid cells involved in the auto-immune process. We recently reported that B-cell depletion in immune thrombocytopenia induced the appearance of pathogenic long-lived plasma cells in the spleen, which were not present before treatment or in non-auto-immune conditions. The spleen of treated patients produced an excess of the cytokine B-cell activating factor, which in in vitro-cultured splenic cells, could increase the longevity of plasma cells. Our results suggested that, paradoxically, the B-cell depletion itself, by altering the splenic milieu, promoted the differentiation of short-lived auto-immune plasma cells into long-lived ones. We describe the cellular and cytokinic components of the splenic plasma cell niche, notably CD4+ T cells and discuss possible survival factors that could be targeted simultaneously with rituximab-mediated B-cell depletion to interfere with plasma cell persistence.
Population Group Differences in Cognitive Functioning in a National Sample of Israelis 50 Years and Older

This study evaluates population group differences in the cognitive functioning of Israelis 50 years and older. Groups were defined based on year of arrival and preferred language (e.g., veteran Israeli Jews, who arrived in Israel more than two decades ago; new immigrants from the former Soviet Union; and Israeli Arabs). Conducting a cross-sectional analysis of the first wave of SHARE-Israel (the Survey of Health, Aging and Retirement in Europe), the authors found that relative to veteran Israeli Jews, new immigrants from the former Soviet Union were significantly more likely to rate their reading ability as impaired. In addition, there was a significant interaction between population group and education on the arithmetic task. Whereas both veteran Israeli Jews and Israeli Arabs were less likely to demonstrate impaired performance on this task as their level of education increased, new immigrants from the former Soviet Union were less impaired than the other two groups, unrelated to educational level. New immigrants were more impaired on the verbal learning task. However, relative to veteran Israeli Jews, Israeli Arabs were significantly less likely to have an impaired performance on the verbal recall task. Findings are somewhat in contrast with the international literature that has consistently shown that the majority culture outperforms relative to ethnic minorities.

Two Bacteria Phylotypes Are Predominant in the Suiyo Seamount Hydrothermal Plume

ABSTRACT Microbial diversity and populations in a hydrothermal plume that was present inside the caldera of the Suiyo Seamount, a submarine volcano on the Izu-Bonin Arc, were investigated by performing a phylogenetic analysis of the 16S rRNA gene and by using fluorescence in situ hybridization (FISH). Corresponding to transmissivity, an indicator of turbidity, the vertical total cell count as determined by 4′,6′-diamidino-2-phenylindole (DAPI) staining varied from 5.6 × 104 to 1.1 × 105 cells ml−1, and the apparent plume layer was assessed to be at a depth of 1,050 to 1,200 m inside the caldera and to contain 1.0 × 105 to 1.1 × 105 cells ml−1. From microbial samples collected in the plume by an in situ filtration system, the following two major phylogenetic groups, which were closely related to sulfur-oxidizing microbes, were obtained: the SUP05 group belonging to the gamma subclass of the Proteobacteria (13 of 20 clones) and the SUP01 group belonging to the epsilon subclass of the Proteobacteria (5 of 20 clones). Specific oligonucleotide probes for these groups (SUP05-187 and SUP01-63) were designed and were used with various water samples obtained from the Suiyo Seamount. In the apparent plume layer, up to 66% of the total counts of microbial cells were estimated to be Bacteria cells that hybridized to EUB338, and few cells were identified by the archaeal probe ARCH915. Almost all Bacteria cells were hard to identify with the known group-specific probes, such as ALF19, GAM42a, and CF319, while 88 to 90% of the Bacteria cells hybridized with SUP05-187 and >98% of them were considered members of the SUP05 and SUP01 populations. In a low-temperature vent fluid emitted from a bivalve-colonized mound, the SUP05 cells accounted for >99% of the Bacteria cells, suggesting that a portion of the plume cells originated on the surface of the seafloor at a depth of about 1,380 m. From further analysis of cell morphology (i.e., cell size and cell elongation index) we inferred that the SUP05 cells were active in the plume layer at a depth of 1,050 to 1,200 m compared to the activity in a near-bottom layer, while many elongated cells were found between these layers. These findings suggest that the morphology and distribution of SUP05 cells have complex relationships with hydrothermal activities and water circulation. Although growth and production rates remain to be defined, we concluded that this Suiyo Seamount caldera has functioned as a natural continuous incubator for these two phylotypes of Bacteria in an aphotic deep-sea environment.
Economic Growth and the Transition from Traditional to Modern Energy in Sweden

We examine the role of substitution from traditional to modern energy carriers and of differential rates of innovation in the use of each of these in economic growth in Sweden from 1850 to 1950. We use a simple growth model with a nested CES production function and exogenous factor-augmenting technological change and carry out a counterfactual simulation based on the econometric results. Even though the rate of technical change was higher for modern energy, innovation in the use of traditional energy carriers contributed more to growth between 1850 and 1890, since the cost share of traditional energy was so much larger than that of modern energy in that period. However, after 1890 we find that modern energy contributed much more to economic growth than traditional energy, but, increasingly, labor-augmenting technological change became the most important single driver of growth.
Fast numerical simulation of crustal deformation using a three-dimensional high-fidelity model

The accumulation of observational data at high resolution has increased the demand for numerical simulation of crustal deformation using 3-D high-ﬁdelity models. In this study, an automatic mesh-generation method for a 3-D high-ﬁdelity ﬁnite element model without computer-aided design model or manual tuning was developed and then used in a fast numerical simulation of crustal deformation. The calculation is accelerated by an iterative solver based on a geometric multigrid, variable preconditioning and multiple-precision arithmetic. After verifying the accuracy of the proposed method, we conducted a numerical simulation of the crustal deformation of a giant earthquake to demonstrate its usefulness.
Fast Image ( Infomatoin ) Retrieval ( IR ) Using Wavelet Coding

Image Retrieval (IR) is one of the most exciting and fastest growing research areas in the field of infomation technology. Large and distributed collections of scientific, artistic, and commercial data comprising images, text, audio and video abound in our information-based society [1]. There must be an effective and precise method for users to search, browse, and interact with these large collections and do so in a timely manner. A common ground in most of current IR systems is to exploit low-level features such as color, texture and shape, which can be extracted by a machine automatically. While semantic level retrieval would be more desirable for users, given the current state of technology in image understanding, this is still very difficult to achieve. This is especially true when one has to deal with a heterogeneous and unpredictable image collection such as from the Internet. Most current feature extraction techniques suffer from the problem that they do not retain any spatial information. Some more recent systems exploited wavelet basis coefficient to cope with this problem. Wavelets provide a powerful and efficient mathematical tool to process images at multiple scales. Wavelets can decomposite fine(high dimensional) images into coarse resolutions. That is, the wavelets scale(downsample) large image into smaller one. Then traditional methods, such as histogram feature extractions, are used to do image retrieval with these coarse images. This improves the image retrieval speed. In addition, wavelet decomposition provides a very good approximation of images and the underlying multi-resolution ability allows the retrieval process to be done progressively. In this project, the wavelets scale the large image into smaller(more coarse) image, then traditional histogram methods are used to do image retrieval. Then this method is compared with the traditional methods in terms of searching speeds and retrieval results. In this paper a fast image retrieval method based on wavelets coding is used to best match the image from image database. Matlab is used to realize this image retrieval method. Simulation results are discussed in details. At last applications are addressed based on wavelets image retrieval.

A MATLAB Toolbox for Finding Stabilizing Controllers for a Class of Switched Systems

This paper presents a MATLAB toolbox that computes stabilizing state feedback controllers for a class of switched systems where the system dynamics switch interchangeably between several subsystems. The subsystems considered here are restricted to second order linear systems. The toolbox finds controllers that stabilize the system under arbitrary switching, where this is ensured by first determining the existence of a common Lyapunov function. To find the common Lyapunov function, the toolbox makes use of an algorithm that is less computationally demanding compared to methods based on solving linear matrix inequalities.
Meeting bulk density sampling requirements efficiently to estimate soil carbon stocks

Estimation of soil organic carbon stocks requires bulk density (BD) measurements. Variability in BD contributes to carbon stock uncertainty, in turn affecting how large a change in stock can be observed over time or space. However, BD is difficult and time-consuming to measure, and sample collection is further complicated by extremely dry field conditions, coarse-textured soils, and high coarse-fragment content, which are common in southern Australia and other semi-arid and Mediterranean-type climates. Two alternatives to reduce BD sampling effort are to take fewer BD samples at a site (i.e. volumetric rings or clod), and to use more time-efficient methods (i.e. gamma–neutron density meter, NDM). We evaluate these options in the context of a soil carbon stock survey in agricultural land in the south-west of Australia. The BD values within a monitoring site measured with conventional and NDM methods were statistically different when assessed using large sample sizes; the measurements diverged where the coarse fraction volume was >20%. However, carbon stocks were equivalent, reflecting the much larger relative variability in carbon percentage, which contributed 84–99% of the uncertainty in carbon stocks compared with <5% from BD. Given the maximum variability measured, soil carbon stock changes in southern Australia should be monitored on a decadal scale.
Initial model results for Arctic mixed layer circulation under a refreezing lead

At the temperatures in the Arctic Ocean mixed layer during lead-induced surface water cooling, convection is primarily salinity controlled owing to continuous brine expulsion from newly forming ice. A nonlinear, time-dependent, convective model has been developed that simulates existing field data obtained on the circulation characteristics under and near a refreezing lead. The model uses typical Arctic Ocean ambient conditions as initial input and allows for imposition of varying geostrophic currents. The zero geostrophic current (free convective case) model output for typical lead surface salt input resulted in maximum horizontal current velocities of 0.05 m s−1, eddy viscosities on the order of 0.01 m2 s−1, average salt fluxes beneath the lead of 3.3×10−5 kg m−2 s−1, and a subsequent increase in the depth of the mixed layer. The circulation cells are symmetric with respect to the lead axis. Imposition of a cross lead constant geostrophic current shows a resultant circulation cell asymmetry associated with increased salt advection in a forced convective regime.
