Research on image retrieval technology based on image fingerprint and color features

Content based video retrieval and content-based image retrieval are the hot research topics in recent years. Image feature extraction has played a very important role in the retrieval process. In this paper, we use the image color features and the image fingerprint extracted by the improved perceptual hash algorithm. In order to combine these two features, we have done a lot of tests to find the optimal weight values. We used these to have image retrieval experiments on Corel set and analyzed the results. Experiments show that the improved algorithm has higher retrieval efficiency and the precision of retrieval result is improved.
SDS-PAGE Analysis of Soluble Proteins in Reconstituted Milk Exposed to Different Heat Treatments

This paper deals with the investigation of the impact of the heat treatment of reconstituted skim milk conducted at different temperatures, and the adding of demineralized whey on the protein solubility, soluble protein composition and interactions involved between proteins in a chemical complex. Commercial skim milk has been reconstituted and heat treated at 75°C, 85°C and 90°C for 20 minutes. Demineralized whey has been added in concentrations of 0.5%, 1.0 and 2.0%. The soluble protein composition has been determined by the polyacrilamide gel electrophoresis (SDS-PAGE) and by the densitometric analysis. Due to the different changes occurred during treatments at different temperatures, proteins of heat-treated samples containing added demineralized whey have had significantly different solubility. At lower temperatures (75°C and 85°C) the adding of demineralized whey decreased the protein solubility by 5.28%-26.41%, while the addition of demineralized whey performed at 90°C increased the soluble protein content by 5.61%-28.89%. Heat treatments, as well as the addition of demineralized whey, have induced high molecular weight complex formation. β-Lg, α-La and κ-casein are involved in high molecular weight complexes. The disulfide interactions between denatured molecules of these proteins are mostly responsible for the formation of coaggregates. The level of their interactions and the soluble protein composition are determined by the degree of temperature.
Polylog-time and near-linear work approximation scheme for undirected shortest paths

Shortest paths computations constitute one of the most fundamental network problems. Nonetheless, known parallel shortest-paths algorithms are generally inefficient: they perform significantly more work (product of time and processors) than their sequential counterparts. This gap, known in the literature as the “transitive closure bottleneck,” poses along-standing open problem. Our main result is an O(mn’O + s(m + nl+’O )) work polylog-time randomized algorithm that computes paths within (1+0(1/ polylog n)) of shortest from s source nodes to alI other nodes in weighted undirected networks with n nodes and m edges (for any fixed co > O). This work bound nearly matches the O(sm) sequential time. In contrast, previous polylog-time algorithms required min { 6( n3 ), ~ (m2 ) } work (even when s = 1), and previous near-linear work algorithms required near-O(n) time. Another result is faster shortest-paths algorithms if accurate distances are required only between “distant” vertices: We obtain an O((m + sn)n’” ) time algorithm that computes paths of weight (1 + 0(1/ pdybg n))dist + o(w~. polylog n), where dist is the corresponding distance and wmaX is the maximum edge weight. Our chief instrument, which is of independent int crest, are efficient constructions of sparse hop sets. A (d, c)-hop set of a network G = (V, E) is a set E* of new weighted edges such that minimum-weight d-edge pat hs in (V, E u E*) have weight within (1 + c) of the respective dist antes in G. We construct hop sets of size O(nl+’O ) where e = 0(1/ polylog n) and d = O(polylog n).
Essays on the effects of oil price shocks and monetary shocks on labor reallocation

ESSAYS ON THE EFFECTS OF OIL PRICE SHOCKS AND MONETARY SHOCKS ON LABOR REALLOCATION by MOHAMAD B. KARAKI December 2012 Advisor: Dr. Ana María Herrera Major: Economics Degree: Doctor of Philosophy The debate regarding the asymmetric effects associated with oil and monetary shocks on the economy has revived interest in analyzing the channels of transmission that generate asymmetries in the response of economic activity to these shocks. This dissertation examines the role of the allocative channel in the transmission mechanism of oil shocks and monetary shocks on economic activity. Using methods by Kilian and Vigfusson (2011b), we analyze the impact of oil and monetary shocks on job creation and job destruction in manufacturing industries. We found that an unanticipated positive oil price shock triggers costly reallocation of labor across sectors and regions. Yet, no evidence of asymmetry was found in the response of job creation (job destruction) to positive and negative oil price shocks. Moreover, we found significant evidence of asymmetries in the response of job creation and job destruction to a positive monetary shock. This finding indicates that there is a significant costly labor reallocation process associated with an unanticipated increase in interest rates. Finally we inquire on whether the reduction in the effect of shocks since the Great moderation could be explained with the decline in the role of the allocative channel. We found that the effect of both oil price shocks and monetary shocks on Labor reallocation has reduced since the start of the Great Moderation. 130 AUTOBIOGRAPHICAL STATEMENT Mohamad Karaki Education: Masters of Arts, Economics, Wayne State University, Detroit, MI, December 2008 Bachelor of Arts, Economics with distinction, University of Michigan-Dearborn, Dearborn, MI, May 2007 Work Experience: 08/2012 present, Visiting Assistant Professor, Oakland University, Rochester, MI 11/2011 present, Consultant, World Bank, Washington D.C. 08/2009 present, Adjunct online faculty, Davenport University, Grand Rapids, MI 08/2007 12/2011, Part-time Lecturer, Wayne State University, Detroit, MI 01/2010 12/2011, Lecturer, University of Michigan-Dearborn, Dearborn, MI Presentations: Annual meetings of the Midwest Macroeconomics Meetings: Session Chair: Shocks, May 13th 2012.

Time Triggered Communication on CAN ( Time Triggered CAN-TTCAN )

Connecting microcontrollers, sensors and actuators by several communication systems is state of the art within the electronic architectures of modern vehicles. Today’s communication is widely based on the event triggered communication on the Controller-Area-Network (CAN) communication protocol. The arbitrating mechanism of this protocol ensures, that all messages are transferred according to the priority of their identifiers and the message with the highest priority will not be disturbed. In the future some mission critical subnetworks within the upcoming generations of vehicle systems, e.g., x-by-wire systems (xbws), will require additionally deterministic behavior in communication during service. Even at maximum bus load, the transmission of all safety related messages must be guaranteed. Moreover it must be possible to determine the point of time when the message will be transmitted with high precision. One way to solve this issue using CAN is the extension of the standard CAN protocol to a time triggered protocol TTCAN. The communication is based on the periodic transmission of a reference message by a time master. This allows to introduce a system wide global network time with high precision. Based on this time the different messages are assigned to time windows within a basic cycle. A big advantage of TTCAN compared to classic scheduled systems is the possibility to transmit event triggered messages in certain "arbitrating" time windows as well. These time windows, where normal arbitration takes place, allow the transmission of spontaneous messages. This paper describes this extension “TTCAN” as it is accepted in TC22/SC3/WG1/TF6 (ISO11898-4) as the common base for the standardization work.
Effect of Watermelon Silver Mottle Virus on the Life History and Feeding Preference of Thrips palmi

Thrips-borne tospoviruses cause numerous plant diseases that produce severe economic losses worldwide. In the disease system, thrips not only damage plants through feeding but also transmit causative agents of epidemics. In addition, thrips are infected with tospoviruses in the course of virus transmission. Most studies on the effect of tospoviruses on vector thrips have focused on the Tomato spotted wilt virus–Frankliniella occidentalis system. Thus, we focused on another thrips-borne tospovirus, Watermelon silver mottle virus (WSMoV), to examine the effect of virus infection on its vector, Thrips palmi. In this study, the direct and indirect effects of WSMoV on the life history traits and feeding preference of T. palmi were examined. The survival rate and developmental time of the WSMoV-infected larval thrips did not differ significantly from those of the virus-free thrips. Comparing the developmental time of larval thrips fed on the healthy plants, thrips-damaged plants, and thrips-inoculated plants (the WSMoV-infected plants caused by thrips feeding), feeding on the thrips-damaged plants reduced the developmental time, and the WSMoV infection in host plants partially canceled the effect of thrips damage on the developmental time. In addition, no significant variations between the virus-free and WSMoV-infected adult thrips regarding longevity and fecundity were observed. These results implied that WSMoV did not directly affect the life history traits of T. palmi, but the WSMoV infection indirectly affected the development of T. palmi through the virus-infected plants. Furthermore, feeding preference tests indicated that T. palmi preferred feeding on either the thrips-damaged plants or the thrips-inoculated plants to the healthy plants. The effect of tospoviruses on the life history and feeding preference of vector thrips might vary among host plants, virus species, vector species, and environmental factors.
Dual Lipolytic Control of Body Fat Storage and Mobilization in Drosophila

Energy homeostasis is a fundamental property of animal life, providing a genetically fixed balance between fat storage and mobilization. The importance of body fat regulation is emphasized by dysfunctions resulting in obesity and lipodystrophy in humans. Packaging of storage fat in intracellular lipid droplets, and the various molecules and mechanisms guiding storage-fat mobilization, are conserved between mammals and insects. We generated a Drosophila mutant lacking the receptor (AKHR) of the adipokinetic hormone signaling pathway, an insect lipolytic pathway related to ß-adrenergic signaling in mammals. Combined genetic, physiological, and biochemical analyses provide in vivo evidence that AKHR is as important for chronic accumulation and acute mobilization of storage fat as is the Brummer lipase, the homolog of mammalian adipose triglyceride lipase (ATGL). Simultaneous loss of Brummer and AKHR causes extreme obesity and blocks acute storage-fat mobilization in flies. Our data demonstrate that storage-fat mobilization in the fly is coordinated by two lipocatabolic systems, which are essential to adjust normal body fat content and ensure lifelong fat-storage homeostasis.
New Insights into HTLV-1 Particle Structure, Assembly, and Gag-Gag Interactions in Living Cells

Human T-cell leukemia virus type 1 (HTLV-1) has a reputation for being extremely difficult to study in cell culture. The challenges in propagating HTLV-1 has prevented a rigorous analysis of how these viruses replicate in cells, including the detailed steps involved in virus assembly. The details for how retrovirus particle assembly occurs are poorly understood, even for other more tractable retroviral systems. Recent studies on HTLV-1 using state-of-the-art cryo-electron microscopy and fluorescence-based biophysical approaches explored questions related to HTLV-1 particle size, Gag stoichiometry in virions, and Gag-Gag interactions in living cells. These results provided new and exciting insights into fundamental aspects of HTLV-1 particle assembly—which are distinct from those of other retroviruses, including HIV-1. The application of these and other novel biophysical approaches promise to provide exciting new insights into HTLV-1 replication.
MOEA/D with adaptive operator selection for the environmental/economic dispatch problem

Adaptive Operator Selection (AOS) is a method used to dynamically determine which operator should be applied in an optimization algorithm based on its performance history. Upper Confidence Bound (UCB) algorithms have been successfully applied for this task due to its ability to tackle the Exploration versus Exploitation (EvE) dilemma presented on AOS. However, it is important to note that the use of UCB algorithms for AOS is still incipient on Multiobjective Evolutionary Algorithms (MOEAs) and many contributions can be made. The aim of this paper is to extend the study of UCB based AOS methods, applying it to a real world problem: the Environmental/Economic Load Dispatch (EELD). Three methods are proposed: MOEA/D-UCB1, MOEA/D-UCB-T and MOEA/D-UCB-V. In these proposals the UCB-based algorithms from the Multi-Armed Bandit (MAB) literature are combined with MOEA/D (MOEA based on decomposition), one of the most successful MOEAs. A pool of operators composed of four Differential Evolution operators is used. The proposed approaches are evaluated in three known instances of the multi-objective environmental/economic dispatch problem, formulated as a nonlinear constrained optimization problem with competing objectives. Experimental results demonstrate that MOEA/D-UCB1 and MOEA/D-UCB-T can be favorably compared with state-of-the-art algorithms reported in the literature for all considered instances.
Accelerated diabetic glomerulopathy in galectin‐3/AGE receptor 3 knockout mice

Several molecules were shown to bind advanced glycation end products (AGEs) in vitro, but it is not known whether they all serve as AGE receptors and which functional role they play in vivo. We investigated the role of galectin‐3, a multifunctional lectin with (anti)adhesive and growth‐regulating properties, as an AGE receptor and its contribution to the development of diabetic glomerular disease, using a knockout mouse model. Galectin‐3 knockout mice obtained by gene ablation and the corresponding wild‐type mice were rendered diabetic with streptozotocin and killed 4 months later, together with age‐matched nondiabetic controls. Despite a comparable degree of metabolic derangement, galectin‐3‐deficient mice developed ac‐celerated glomerulopathy vs. the wild‐type animals, as evidenced by the more pronounced increase in protein‐uria, extracellular matrix gene expression, and mesan‐gial expansion. This was associated with a more marked renal/glomerular AGE accumulation, indicating it was attributable to the lack of galectin‐3 AGE receptor function. The galectin‐3‐deficient genotype was associated with reduced expression of receptors implicated in AGE removal (macrophage scavenger receptor A and AGE‐R1) and increased expression of those mediating cell activation (RAGE and AGE‐R2). These results show that the galectin‐3‐regulated AGE receptor pathway is operating in vivo and protects toward AGE‐induced tissue injury in contrast to that through RAGE. —Pugliese, G. , Pricci, F. , Iacobini, C. , Leto, G. , Amadio, L. , Barsotti, P., Frigeri L. , Hsu, D.

Correlation k-clustering with pre-clustered items on cactus graphs

Given a graph G=(V, E) with real-valued edge weights, the problem of correlation k-clustering with pre-clustered items is to extend a k-clustering of distinguished vertices of G (pre-clustered items) to partition all the vertices into clusters so as to minimize the total absolute weight of cut positive edges and uncut negative edges. This problem for general graphs is APX-complete. A polynomial time exact algorithm for cactus graphs is presented.
Mitigating Supply Chain System Entropy by the Implementation of RFID

Information transfer in the supply chain is complex and causes instability and unpredictable behavior, when information transferred is incomplete or incorrect. This instability is characterized by the Bullwhip Effect that represents concretization of entropy, namely the degree of disorder within a system. In this paper we assume that "complete" and "accurate" real-time information sharing concerning product and inventory levels through RFID reduces entropy and limits its effects on the supply chain. RFID can reduce information loss and increase accuracy. From the literature we show that RFID can improve visibility, reduce uncertainty and complexity of the supply chain permitting us to conclude that it represents a regulatory mechanism of informational entropy in the supply chain.

Estimating Completeness in Streaming Graphs

Finding the completeness of a graph is important from vari- ous aspects. Considering the massive growth and dynamics of real-life networks, we readdress this problem in a stream- ing setting. We approach the problem of verifying the com- pleteness of a graph by estimating the eigen values of a sketch of its adjacency matrix. Here, we provide the first approximation algorithm for estimating the completeness of ab ipartite graph in the streaming model. The approach is further generalized for any arbitrary simple graph. We em- ploy some useful recent results on` 1 heavy eigen-hitters to construct the algorithms working in linear time and consum- ing sublinear space. The implementation of the algorithms have also been done and tested on a couple of networks. We illustrate the e↵ectiveness of the proposed approaches in analyzing social, biological and other real-life networks.
The Agreedness between Observation and Self-report Method in Work Posture Analysis

Work posture analysis plays an important role in providing safe and productive workplace, through minimizing musculoskeletal symptoms or disorders. The postural analysis can be conducted through observation, direct, and self-report method. Each has their advantages and disadvantages. Purpose of this study is to compare obervation and self-report analysis in the context of degre of agreenes. One rater observes and gives rating to the fifteeen work postures in an automotive service company using Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA). In addition, six workers in the automotive service company also fill out the Nordic questionnaire as a self-report of musculoskeletal symptoms or disorders. Descriptive analysis is conducted to compare the musculoskeletal symptoms using both observer and self-report analysis. Results show that RULA is slighlty better than REBA in accordance to the Nordic questionnaire’ result. Implications of the result is discussed.
A Review of Embodiment in Autism Spectrum Disorders

In classical approaches to cognition, sensory, motor, and emotional experiences are stripped of domain-specific perceptual and sensorimotor information, and represented in a relatively abstract form. In contrast, the embodied cognition framework suggests that our representations retain the initial imprint of the manner in which information was acquired. In this paper, we argue that individuals with autism spectrum disorders (ASD) display impairments in the temporal coordination of motor and conceptual information (as shown in gesture research) and striking deficits in the interpersonal mimicry of motor behaviors (as shown in yawning research) – findings we believe are consistent with an embodied account of ASD that includes, but goes beyond, social experiences and is driven in part by significant but subtle motor deficits. In this paper, we review the research examining an embodied cognition account of ASD, and discuss its implications.
