Proposal and Evaluation of Cyber Defense System Using Blacklist Refined Based on Authentication Results

In recent years, the damage from cyber attacks caused by sophisticated malware has continuously increased. It is therefore becoming more difficult to take countermeasures using traditional approaches such as antivirus and firewall products. Against the intrusion of malware, we propose an automated countermeasure technology system named Autonomous Evolution of Defense, which mitigates the risk of actual damage by controlling the internet connection for malware, and in addition optimizes the system's operating conditions. The system takes countermeasures immediately to mitigate risk without causing disruptive effects on business. However, a graylist of malicious addresses generated by malware analysis systems contains many false-positive addresses and is very "noisy" for use in blocking access based on the list. We therefore propose a new technique for improving the accuracy of the unreliable graylist of addresses using image authentication. We report here on the implementation of our system and results of evaluation.
Purification and Characterization of an Autolysin from Clostridium acetobutylicum

A proteinaceous substance with antibiotic-like activity, resembling that of a bacteriocin, was isolated from an industrial-scale acetone-butanol fermentation of Clostridium acetobutylicum. The substance, purified by acetone precipitation, diethylaminoethyl cellulose chromatography, and polyacrylamide gel electrophoresis, was characterized as a glycoprotein with a molecular weight of 28,000. The glycoprotein was partially inactivated by certain protease enzymes. It had no effect on deoxyribonucleic acid, ribonucleic acid, or protein synthesis, and it did not result in the loss of intracellular adenosine triphosphate. The glycoprotein lysed sodium dodecyl sulfate-treated cells and cell wall preparations, and therefore it is referred to as an autolysin. The autolysin gene appeared to be chromosomal since plasmid deoxyribonucleic acid was not detected in the C. acetobutylicum strain.
Resolving the question of color naming universals

The existence of cross-linguistic universals in color naming is currently contested. Early empirical studies, based principally on languages of industrialized societies, suggested that all languages may draw on a universally shared repertoire of color categories. Recent work, in contrast, based on languages from nonindustrialized societies, has suggested that color categories may not be universal. No comprehensive objective tests have yet been conducted to resolve this issue. We conduct such tests on color naming data from languages of both industrialized and nonindustrialized societies and show that strong universal tendencies in color naming exist across both sorts of language.
Experimental study of the performance of handset adaptive array antennas in the vicinity of a human operator

The purpose of this study is to investigate experimentally the performance of adaptive array antennas in mobile handset terminals using the RLS algorithm as the minimum mean square error (MMSE) in the 2 GHz band. Particular emphasis is placed on how well handset AAA works in a practical environment, where the user's body has an influence on performance. In this paper, two types of dual-element AAA model have been derived, Model A which is a simple model, and Model B which is a more realistic model. In Model A, for the basic study, the array is comprised of two dipole antennas placed close to a cylinder shape phantom. In Model B, for the more practical study, the array is comprised of quarter-wavelength monopole antenna and a planar inverted-F antenna (PIFA), and is placed close to a realistically shaped human phantom. By estimating the correlation between the bit error rate (BER) and the received pattern of the antenna, we describe how a significant enhancement in the ability to reduce interference signals can be achieved, even when the handset is used in proximity to a human operator in a talk situation
Determination of Carotid Artery Atherosclerotic Lesion Type and Distribution in Hypercholesterolemic Patients With Moderate Carotid Stenosis Using Noninvasive Magnetic Resonance Imaging

Background and Purpose— The aims of this study were to noninvasively determine carotid atherosclerotic lesion type and distribution and to evaluate the reproducibility of determining lesion types in asymptomatic patients with moderate hypercholesterolemia and moderate carotid artery (CA) stenosis using MRI. Methods— Forty-two asymptomatic patients with moderate CA stenosis underwent bilateral carotid MRI in a 1.5-T scanner using a protocol that generated 4 contrast weightings (T1, T2, proton density, and 3D time of flight). MRI-modified American Heart Association criteria were used to evaluate lesion types at 3 locations (common and internal CA [CCA and ICA, respectively] and CA bifurcation) and at the minimum lumen area. Two identical MR scans were conducted to evaluate reproducibility of lesion types. Results— Lesion types were obtained from 230 locations. Type III (39%) occurred most commonly, followed by types IV–V (25%), I–II (20%), VI (12%), and VII (4%). Type III was more commonly distributed in the CCA (n=35, 39%) and ICA (n=32, 36%). Type IV–V was more commonly distributed in the CCA (n=24, 41%) and at the bifurcation (n=21, 36%). Forty-two lesions were available at the site of minimum lumen area: type III (33%), IV–V (33%), VI (29%), and VII (5%). There was good agreement of lesion types between both MRI scans (Cohen's &kgr;=0.73; 95% CI: 0.65 to 0.81). Conclusions— MRI can determine lesion types reproducibly as well as the distribution of lesions in hypercholesterolemic patients with moderate CA stenosis. A wide range of lesion types, including advanced lesions, were found in these patients.
Quality of Information (QoI)-aware cooperative sensing in vehicular sensor networks

Recently, the vehicular sensor network (VSN) is emerging as an efficient solution for executing different sensing tasks in urban environments. However, due to the heterogeneity of vehicles in sensing capability and uncontrollable movement trajectory, it is a challenge to best provide the required quality of information (QoI) of the sensing task in VSNs. In this paper, we introduce a VSN architecture, in which multiple vehicles cooperatively sense a particular urban area of interest, and process the sensed data to achieve the QoI requirements while considering incentives for environment sensing, data processing and communication. Furthermore, we formulate and solve an optimization problem for determining the optimal sampling rates for vehicles with the objective of minimizing the total incentive under the constraints related to QoI requirements. Various numerical results based on realistic vehicular traces are presented to justify the effectiveness of proposed approach in the vehicles' QoI-aware cooperative sensing operations.
Characterization of Salmonella Enteritidis isolated from foods and patients in northern Morocco.

OBJECTIVES This study aimed to investigate Salmonella Enteritidis strains isolated from human and food sources in the north of Morocco by means of phenotypic and genotypic methods. METHODOLOGY Fifteen isolates from humans and food were submitted to phage typing, XbaI-macrorestriction (pulsed field gel electrophoresis [PFGE]), enterobacterial repetitive intergenic consensus (ERIC-PCR), antimicrobial susceptibility testing, and PCR assay targeting the spvR and invA genes. RESULTS Six fingerprinting profiles were obtained with the ERIC-PCR method, four with PFGE profiling, five with antimicrobial resistance, three with phage typing, and only one with plasmid profiling. spvR gene was detected in six strains, which did not harbour plasmids of 90 kb. CONCLUSIONS The conclusions of this study are drawn from a limited number of isolates. It would be desirable to investigate a greater and more diverse population of Salmonella isolates. S. Enteritidis was genotyped and showed four different patterns by PFGE and six by ERIC-PCR. Accordingly, high genetic similarity and limited genetic diversity were found for these strains from north of Morocco.
Exalt: Empowering Researchers to Evaluate Large-Scale Storage Systems

This paper presents Exalt, a library that gives back to researchers the ability to test the scalability of today's large storage systems. To that end, we introduce Tardis, a data representation scheme that allows data to be identified and efficiently compressed even at low-level storage layers that are not aware of the semantics and formatting used by higher levels of the system. This compression enables a high degree of node colocation, which makes it possible to run large-scale experiments on as few as a hundred machines. Our experience with HDFS and HBase shows that, by allowing us to run the real system code at an unprecedented scale, Exalt can help identify scalability problems that are not observable at lower scales: in particular, Exalt helped us pinpoint and resolve issues in HDFS that improved its aggregate throughput by an order of magnitude.
Effects of estrogen deficiency and bisphosphonate therapy on osteocyte viability and microdamage accumulation in an ovine model of osteoporosis

It has been proposed that osteocyte viability plays an important role in bone integrity, and that bone loss in osteoporosis may be partially due to osteocyte cell death following estrogen depletion. Osteoporosis treatments such as bisphosphonates can inhibit osteocyte apoptosis which in turn may also reduce remodeling. Consequently, microcracks in bone which are normally repaired by bone remodeling may accumulate. This study used an ovine model of osteoporosis to examine the effects of estrogen depletion and bisphosphonates on osteocyte apoptosis and microdamage accumulation. Skeletally mature ewes were randomly assigned into two equal groups; ovariectomy (OVX) and a non‐treatment group (control). Half of these animals were sacrificed 12 months post‐OVX. Twenty months post‐OVX, a number of OVX animals were randomly selected and each received a supra‐pharmacological dose of the bisphosphonate, zoledronic acid (Zol). This group and all the remaining animals were sacrificed 31 months post‐OVX. A compact bone specimen was removed from the left metacarpal of each animal; half was used for osteocyte apoptosis detection and the remainder for microdamage analysis. Estrogen deficiency resulted in significant increases in the levels of osteocyte apoptosis while zoledronic acid significantly reduced the level of apoptosis in osteocytes. Zoledronic acid treatment resulted in the formation of more microcracks. However, these cracks were shorter than in control or OVX groups which may provide one explanation as to why increased damage levels following bisphosphonate treatment have not lead to increased fractures. This study also provides additional evidence of the importance of estrogen in preserving the osteocyte network. © 2010 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

Correcting faults in write-once memory

We consider codes for write-once memory in tile presence of stuck-agO and stuebat--1 faults. Such fault.tolerant codes generally require less redundancy than error-correcting codes, as faults detected during the writing process can affect subsequent behavior of that process. We present pointer codes, which use part of a codeword to point to faults in other parts of the codeword. A pointer code can encode n-bit messages in the presence of f faults with only f(log 2 n + o(1)) redundancy. We derive a lower bound on the redundancy of such a fault-tolerant code of slightly less than f log n. We also examine some models where all stuck-at inforIlmtion is known in advance, and analyze the expected redundancy of pointer codes.

Modeling Dynamic Relationships Between Characters in Literary Novels

Studying characters plays a vital role in computationally representing and interpreting narratives. Unlike previous work, which has focused on inferring character roles, we focus on the problem of modeling their relationships. Rather than assuming a fixed relationship for a character pair, we hypothesize that relationships are dynamic and temporally evolve with the progress of the narrative, and formulate the problem of relationship modeling as a structured prediction problem. We propose a semi-supervised framework to learn relationship sequences from fully as well as partially labeled data. We present a Markovian model capable of accumulating historical beliefs about the relationship and status changes. We use a set of rich linguistic and semantically motivated features that incorporate world knowledge to investigate the textual content of narrative. We empirically demonstrate that such a framework outperforms competitive baselines.
Lymphocyte mRNA analysis of the ornithine transcarbamylase gene in Italian OTCD male patients and manifesting carriers: Identification of novel mutations

A new simple, non‐invasive method using ornithine transcarbamylase (OTC) mRNA isolated from peripheral blood (PBL) or lymphoblastoid cell lines has been performed. This approach based on reverse transcription and nested PCR to obtain a double strand PBL OTC cDNA allowed the identification of genetic lesions in five Italian families affected by OTC deficiency (OTCD). In the PBL OTC mRNA two new mutations, T262K and W265L, have been detected in three unrelated male OTCD patients with mild symptoms. One known mutation, T264A, has been identified in one manifesting carrier. The known mutation E310X, detected on genomic DNA of another manifesting carrier, failed to be detected in her PBL OTC mRNA because of the presence of a STOP codon. All mutations have been confirmed in the patients' and their relatives' genomic DNA. In three patients the mutations have also been confirmed in the mRNA isolated from frozen liver biopsy. The T262K aminoacid substitution has been detected in a male's PBL OTC mRNA at homozygous state while a heterozygous pattern has been detected at the genomic DNA level, suggesting that the patient is a somatic mosaic for this mutation. Here we show that PBL OTC mRNA analysis is useful to detect genetic lesions in male and female OTCD patients. Hum Mutat 15:380–381, 2000. © 2000 Wiley‐Liss, Inc.
Altered pituitary-adrenal axis responses to provocative challenge tests in adult survivors of childhood abuse.

OBJECTIVE Early adverse life events may predispose individuals to the development of mood and anxiety disorders in adulthood, perhaps by inducing persistent changes in corticotropin-releasing factor (CRF) neuronal systems. The present study sought to evaluate pituitary-adrenal responses to standard hypothalamic-pituitary-adrenal axis challenge tests in adult female survivors of childhood abuse with and without major depressive disorder. METHOD Plasma ACTH and cortisol responses to the administration of 1 microg/kg ovine CRF and plasma cortisol responses to the administration of 250 microg ACTH(1-24) were measured in healthy women without early life stress (N=20), women with childhood abuse without major depressive disorder (N=20), women with childhood abuse and major depressive disorder (N=15), and women with major depression but no early life stress (N=11). RESULTS Abused women without major depressive disorder exhibited greater than usual ACTH responses to CRF administration, whereas abused women with major depressive disorder and depressed women without early life stress demonstrated blunted ACTH responses. In the ACTH(1-24) stimulation test, abused women without major depressive disorder exhibited lower baseline and stimulated plasma cortisol concentrations. Abused women with comorbid depression more often suffered from posttraumatic stress disorder and reported more recent life stress than abused women without major depressive disorder. CONCLUSIONS These findings suggest sensitization of the anterior pituitary and counterregulative adaptation of the adrenal cortex in abused women without major depressive disorder. On subsequent stress exposure, women with a history of childhood abuse may hypersecrete CRF, resulting in down-regulation of adenohypophyseal CRF receptors and symptoms of depression and anxiety.
Target acquisition with camera phones when used as magic lenses

When camera phones are used as magic lenses in handheld augmented reality applications involving wall maps or posters, pointing can be divided into two phases: (1) an initial coarse physical pointing phase, in which the target can be directly observed on the background surface, and (2) a fine-control virtual pointing phase, in which the target can only be observed through the device display. In two studies, we show that performance cannot be adequately modeled with standard Fitts' law, but can be adequately modeled with a two-component modification. We chart the performance space and analyze users' target acquisition strategies in varying conditions. Moreover, we show that the standard Fitts' law model does hold for dynamic peephole pointing where there is no guiding background surface and hence the physical pointing component of the extended model is not needed. Finally, implications for the design of magic lens interfaces are considered.
Multiphysics Modeling: Electro-Vibro-Acoustics and Heat Transfer of PWM-Fed Induction Machines

The design of variable-speed electrical machines involves several fields of physics, such as electromagnetism, thermics, mechanics, and also acoustics. This paper describes the analytical multiphysics models of a computer-aided-design software which is applied to inverter-fed traction induction machines. The electromagnetic model computes rotor and stator currents, the induction-machine traction characteristics, and the radial air-gap flux density. The mechanical and acoustic models compute the motor's audible magnetic noise level due to Maxwell forces. The thermal model based on 3-D nodal network computes the transient temperature of different parts of the motor. These fast models make it possible to couple the software with some optimization tools. Some simulation results are presented on a self-ventilated closed motor and compared to experiments.
A channel allocation algorithm for OSA-enabled IEEE 802.11 WLANs

Channel allocation problem is a major challenge in wireless local area networks (WLANs), especially in dense deployments of access points (APs) where congestion of the unlicensed spectrum bands (i.e., ISM bands) could undermine achieved network performance. This paper analyses the possibility to alleviate congestion of the ISM band by allowing some APs to use additional channels located in licensed bands in an opportunistic manner whenever licensee services (i.e., primary users) are not affected. Availability of these additional channels in licensed bands is assumed not to be the same for all the APs. Based on this assumption, we formulate the problem for the channel assignment as a Binary Linear Programming (BLP) problem, which allows us to obtain an optimal solution despite an elevated execution time. We also develop a heuristic method based on building a Minimum Spanning Tree (MST) graph attending to interference conditions that is able to find near-optimal solutions with a shorter execution time. Results are provided to assess the benefits of such a proposal under different WLAN deployment situations and primary channel availability conditions.
MIPS issues in Grid Computing

Grid computing is very beneficial application which is sharing their resources on different node. There is a large number of user access the data. The basic principal of Grid computing are that data entering by the user is not store locally, but it store in data center on internet. The reliability of the Grid depends on how the loads are being handle. Load balancing means distributing workload across multiple computing resources. Load balancing must take into two major tasks one is the resource providing or resource allocation and second is task scheduling in distributed environment. Many researchers have been proposed various techniques to improve the load balancing. This paper implements the execution time by using the proposed algorithms. Our objective is to develop load balancing algorithm by using Ant Colony Based Algorithms (ACO). Keywords—ACO, Grid Computing, MIPS rating.
Optimum synchronization of frames with unknown, variable lengths on Gaussian channels

In this paper, we study frame synchronization based on the sync word in the general case when the frame size is unknown and possibly variable on a frame by frame basis. We assume a Gaussian channel with binary symbols and coherent decoding, where soft values are provided to the frame synchronizer. According to the hypothesis testing theory, the optimum likelihood ratio test (LRT) is derived using the Neyman-Pearson lemma. Then, the performance of the test is analytically assessed. The obtained closed form expressions allow also the derivation of the receiver operating characteristic (ROC) curves for the LRT synchronizer, showing that a remarkable gain is obtained with respect to synchronization based on a correlation metric.
Complex dynamics of human red blood cell flickering: alterations with in vivo aging.

Human red blood cells (RBCs) exhibit vibratory motions, referred to as "flickering. " Their dynamical properties, classically attributed to thermal mechanisms, have not been fully characterized. Using detrended fluctuation analysis and multiscale entropy methods, we show that the short-term flickering motions of RBCs, observed under phase contrast microscopy, have a fractal scaling exponent close to that of 1f noise and exhibit complex patterns over multiple time scales. Further, these dynamical properties degrade with in vivo aging such that older cells that have been in the circulation longer generate significantly (p<0.003) less complex flickering patterns than newly formed cells. Quantitative assessment of multiscale flickering may provide a way of measuring RBC functionality. Membrane models need to account for the complex properties of these motions and their changes with in vivo senescence.
