    Rad, Babak Bashari; Ibrahim, Suhaimi

    2011-01-01

    This paper presents a general overview on evolution of concealment methods in computer viruses and defensive techniques employed by anti-virus products. In order to stay far from the anti-virus scanners, computer viruses gradually improve their codes to make them invisible. On the other hand, anti-virus technologies continually follow the virus tricks and methodologies to overcome their threats. In this process, anti-virus experts design and develop new methodologies to make them stronger, more and more, every day. The purpose of this paper is to review these methodologies and outline their strengths and weaknesses to encourage those are interested in more investigation on these areas.

  15. Toward Automatic Discovery of Malware Signature for Anti-Virus Cloud Computing

    NASA Astrophysics Data System (ADS)

    Yan, Wei; Wu, Erik

    Security vendors are facing a serious problem of defeating the complexity of malwares. With the popularity and the variety of zero-day malware over the Internet, generating their signatures for detecting via anti-virus (AV) scan engines becomes an important reactive security function. However, AV security products consume much of the PC memory and resources due to their large signature files. AV cloud computing becomes a popular solution for this problem. In this paper, a novel Automatic Malware Signature Discovery System for AV cloud (AMSDS) is proposed to generate malware signatures from both static and dynamic aspects. Our experiments on millions-scale samples suggest that AMSDS outperforms most state-of-the-art automatic signature generation techniques of both industry and academia.

  17. Personal computer security: part 1. Firewalls, antivirus software, and Internet security suites.

    PubMed

    Caruso, Ronald D

    2003-01-01

    Personal computer (PC) security in the era of the Health Insurance Portability and Accountability Act of 1996 (HIPAA) involves two interrelated elements: safeguarding the basic computer system itself and protecting the information it contains and transmits, including personal files. HIPAA regulations have toughened the requirements for securing patient information, requiring every radiologist with such data to take further precautions. Security starts with physically securing the computer. Account passwords and a password-protected screen saver should also be set up. A modern antivirus program can easily be installed and configured. File scanning and updating of virus definitions are simple processes that can largely be automated and should be performed at least weekly. A software firewall is also essential for protection from outside intrusion, and an inexpensive hardware firewall can provide yet another layer of protection. An Internet security suite yields additional safety. Regular updating of the security features of installed programs is important. Obtaining a moderate degree of PC safety and security is somewhat inconvenient but is necessary and well worth the effort. PMID:12975519

  18. Live virus-free or die: coupling of antivirus immunity and programmed suicide or dormancy in prokaryotes

    PubMed Central

    2012-01-01

    Background The virus-host arms race is a major theater for evolutionary innovation. Archaea and bacteria have evolved diverse, elaborate antivirus defense systems that function on two general principles: i) immune systems that discriminate self DNA from nonself DNA and specifically destroy the foreign, in particular viral, genomes, whereas the host genome is protected, or ii) programmed cell suicide or dormancy induced by infection. Presentation of the hypothesis Almost all genomic loci encoding immunity systems such as CRISPR-Cas, restriction-modification and DNA phosphorothioation also encompass suicide genes, in particular those encoding known and predicted toxin nucleases, which do not appear to be directly involved in immunity. In contrast, the immunity systems do not appear to encode antitoxins found in typical toxin-antitoxin systems. This raises the possibility that components of the immunity system themselves act as reversible inhibitors of the associated toxin proteins or domains as has been demonstrated for the Escherichia coli anticodon nuclease PrrC that interacts with the PrrI restriction-modification system. We hypothesize that coupling of diverse immunity and suicide/dormancy systems in prokaryotes evolved under selective pressure to provide robustness to the antivirus response. We further propose that the involvement of suicide/dormancy systems in the coupled antivirus response could take two distinct forms: 1) induction of a dormancy-like state in the infected cell to ‘buy time’ for activation of adaptive immunity; 2) suicide or dormancy as the final recourse to prevent viral spread triggered by the failure of immunity. Testing the hypothesis This hypothesis entails many experimentally testable predictions. Specifically, we predict that Cas2 protein present in all cas operons is a mRNA-cleaving nuclease (interferase) that might be activated at an early stage of virus infection to enable incorporation of virus-specific spacers into the CRISPR locus or to trigger cell suicide when the immune function of CRISPR-Cas systems fails. Similarly, toxin-like activity is predicted for components of numerous other defense loci. Implications of the hypothesis The hypothesis implies that antivirus response in prokaryotes involves key decision-making steps at which the cell chooses the path to follow by sensing the course of virus infection.

  1. Preparation of an antitumor and antivirus agent: chemical modification of ?-MMC and MAP30 from Momordica Charantia L. with covalent conjugation of polyethyelene glycol

    Background Alpha-momorcharin (?-MMC) and momordica anti-HIV protein (MAP30) derived from Momordica charantia L. have been confirmed to possess antitumor and antivirus activities due to their RNA-N-glycosidase activity. However, strong immunogenicity and short plasma half-life limit their clinical application. To solve this problem, the two proteins were modified with (mPEG)2-Lys-NHS (20 kDa). Methodology/principal findings In this article, a novel purification strategy for the two main type I ribosome-inactivating proteins (RIPs), ?-MMC and MAP30, was successfully developed for laboratory-scale preparation. Using this dramatic method, 200 mg of ?-MMC and about 120 mg of MAP30 was obtained in only one purification process from 200 g of Momordica charantia seeds. The homogeneity and some other properties of the two proteins were assessed by gradient SDS-PAGE, electrospray ionization quadruple mass spectrometry, and N-terminal sequence analysis as well as Western blot. Two polyethylene glycol (PEG)ylated proteins were synthesized and purified. Homogeneous mono-, di-, or tri-PEGylated proteins were characterized by matrix-assisted laser desorption ionization-time of flight mass spectrometry. The analysis of antitumor and antivirus activities indicated that the serial PEGylated RIPs preserved moderate activities on JAR choriocarcinoma cells and herpes simplex virus-1. Furthermore, both PEGylated proteins showed about 60%–70% antitumor and antivirus activities, and at the same time decreased 50%–70% immunogenicity when compared with their unmodified counterparts. Conclusion/significance ?-MMC and MAP30 obtained from this novel purification strategy can meet the requirement of a large amount of samples for research. Their chemical modification can solve the problem of strong immunogenicity and meanwhile preserve moderate activities. All these findings suggest the potential application of PEGylated ?-MMC and PEGylated MAP30 as antitumor and antivirus agents. According to these results, PEGylated RIPs can be constructed with nanomaterials to be a targeting drug that can further decrease immunogenicity and side effects. Through nanotechnology we can make them low-release drugs, which can further prolong their half-life period in the human body. PMID:22802682

  16. El Sistema de Referencia Celeste convencional de la IAU

    NASA Astrophysics Data System (ADS)

    Arias, E. F.

    La Unión Astronómica Internacional (IAU) recomendó la adopción de un nuevo sistema de referencia celeste baricéntrico cuyo plano fundamental y origen de ascensiones rectas estén próximos, respectivamente, al ecuador y equinoccio dinámicos J2000.0. El nuevo sistema de referencia estará materializado por las posiciones J2000.0 de radiofuentes extragalácticas determinadas con la técnica de interferometría de larga línea de base (VLBI). El Working Group on Reference Frames de la IAU (WGRF) decidió adoptar (Grasse, 1995) al sistema de referencia celeste extragaláctico del Servicio Internacional de la Rotación Terrestre (IERS) como futuro sistema de referencia celeste convencional bajo el nombre International Celestial Reference System (ICRS) y encomendó su mantenimiento futuro al IERS. El marco de referencia que materializará al ICRS contiene posiciones precisas J2000.0 de más de 600 radiofuentes extragalácticas. Las coordenadas fueron ajustadas en una única solución VLBI en la cual se incluyeron todas las observaciones realizadas hasta octubre de 1995 con la técnica de adquisición de datos VLBI Mark III. Para minimizar los errores sistemáticos que pueden afectar la calidad del marco de referencia se introdujeron mejoras sustanciales en la modelización y en la selección de datos. Un subconjunto de objetos del marco de referencia se utilizó para referir las posiciones estelares determinadas con el satélite astrométrico Hipparcos al ICRS.

    NASA Astrophysics Data System (ADS)

    Torres, K. B. V.; Vaz, L. P. R.

    2003-08-01

    O código KOREL é uma ferramenta adicional eficiente para a determinação simultânea de parâmetros orbitais espectroscópicos para o desembaraço de espectros individuais de sistemas estelares com até cinco componentes. Estudos já realizados (Torres,KBV,2002, Dissertação de Mestrado DF-ICEx-UFMG) mostram as limitações, aplicabilidade e eficiência do código para sistemas com duas componentes. Apresentamos, neste trabalho, a continuação dos estudos para sistemas com três componentes (sistemas hierárquicos), utilizando espectros sintéticos "gabaritos" de estrelas individuais em órbitas cujos parâmetros são conhecidos "a priori". Geramos os espectros compostos e verificamos como o código reproduz os parâmetros orbitais e espectros individuais em diversas situações físicas. É apresentado, ainda, uma discussão da aplicabilidade do código em sistemas reais como RV Crateris (Machado,ACM,1997, Dissertação de Mestrado DF-ICEx-UFMG), um sistema triplo cujas componentes eclipsantes estão, provavelmente, ainda na fase pré-sequência principal.

    2015-08-01

    A novel bovine interferon-? (BoIFN-?) gene, which encodes a protein of 195 amino acids with a 23-amino acid signal peptide, was amplified from bovine liver genomic DNA through PCR and named BoIFN-?24 according to its position in the bovine genome. In this study, the recombinant protein was expressed in Escherichia coli and antiviral or antiproliferation activity was determined in vitro. Results showed that BoIFN-?24 exhibits high antiviral activity, which can be abrogated using PAb against BoIFN-?24, and inhibits cell proliferation. BoIFN-?24 also presents high sensitivity to trypsin and stability at pH 2.0 or 65°C, which are typical characteristics of type I IFN. This study revealed that BoIFN-?24 is a potential novel effective therapeutic agent and provided a basis for further research on the BoIFN-? multigene family. PMID:25951414

Cas1 is a CRISPR-associated protein that is common to all CRISPR-containing prokaryotes but its function remains obscure. Here we show that the purified Cas1 protein of Escherichia coli (YgbT) exhibits nuclease activity against single-stranded and branched DNAs including Holliday junctions, replication forks, and 5?-flaps. The crystal structure of YgbT and site-directed mutagenesis have revealed the potential active site. Genome-wide screens show that YgbT physically and genetically interacts with key components of DNA repair systems, including recB, recC and ruvB. Consistent with these findings, the ygbT deletion strain showed increased sensitivity to DNA damage and impaired chromosomal segregation. Similar phenotypes were observed in strains with deletion of CRISPR clusters, suggesting that the function of YgbT in repair involves interaction with the CRISPRs. These results show that YgbT belongs to a novel, structurally distinct family of nucleases acting on branched DNAs and suggest that, in addition to antiviral immunity, at least some components of the CRISPR-Cas system have a function in DNA repair.

    In this work we describe some aspects of the dynamics of the mean-motion resonances. Emphasis to the case of resonances between regular satellites of the giant planets will be given, even so some aspects of the physics of the resonances in extra-solar planetary systems are also briefly treated. The role of the resonances in satellites systems is discussed through examples, showing how certain resonances, and its relations with the tidal dissipation effects, can be the key of the explanation of some phenomena still not explained in the Solar System. Amongst some examples we highlight the problem of the resurfacing of Enceladus, the existence of active volcanoes in Io, and the possible existence of the subsurface ocean in Europe. This work has as objective the divulgation of some topics in Celestial Mechanics and Planetary Sciences for an undergraduate public in exact sciences, as Astronomy and Physics, and not their detailed description. Neste trabalho descrevemos alguns aspectos da dinâmica de ressonâncias de movimentos médios. Será dada ênfase maior ao caso de ressonâncias entre satélites regulares dos planetas gigantes, embora alguns aspectos da física das ressonâncias em sistemas planetários extra-solares também sejam discutidos brevemente. A importância do estudo de ressonâncias em sistemas de satélites é discutida mais detalhadamente através de exemplos, mostrando como certas ressonâncias e suas relações com efeitos de dissipação de maré podem ser a chave de parte da explicação de alguns fenômenos ainda não explicados no Sistema Solar. Dentre vários exemplos destacamos o problema da remodelagem da superfície do satélite Enceladus, a existência de vulcões ativos em Io, e a possível existência do oceano subterrâneo em Europa. Este trabalho tem como objetivo a divulgação de alguns tópicos de Mecânica Celeste e Planetologia para um público de nível de graduação em disciplinas na área de exatas, em especial Astronomia e Física, e não a descrição detalhada dos conceitos aqui discutidos.

  16. Projeto do sistema anti-ressonante da fiação dos transdutores para o detector Mario Schenberg

    NASA Astrophysics Data System (ADS)

    Vieira, S. J.., Jr.; Melo, J. L.

    2003-08-01

    O detector de ondas gravitacionais Mario Schenberg está sendo projetado e construído pelo grupo Gráviton. Sua construção está ocorrendo no Laboratório de Estado Sólido e Baixas Temperaturas (LESBT) da Universidade de São Paulo, na cidade de São Paulo. Esse detector possui uma massa ressonante esférica de cobre-alumínio, com 65 cm de diâmetro, pesando aproximadamente 1150 Kg, suspensa por um sistema de isolamento vibracional, que se encontra em fase de testes preliminares. A real eficácia desse sistema, entretanto, só poderá ser comprovada quando o detector estiver aparelhado com, pelo menos, um transdutor eletromecânico de altíssima sensibilidade acoplado à massa ressonante. Neste momento, não só este sistema de isolamento vibracional será posto em teste, como o do projeto da fiação que transporta os sinais de microondas até os transdutores e destes para a pré-amplificação. Apesar dessa fiação ter sido projetada para não apresentar nenhum contato com a superfície esférica da antena, de maneira a não haver nenhuma transmissão de ruído vibracional do laboratório para esta, deve-se minimizar o ruído microfônico produzido nessa fiação por oscilações mecânicas, uma vez que ela não utiliza nenhum sistema de isolamento vibracional. Com o intuito de resolver este problema, projetamos uma estrutura, formada por pequenos cilindros conectados por barras, a qual não terá nenhuma ressonância mecânica na faixa de freqüências de interesse para detecção (3000 - 3400 Hz). Desta forma, as vibrações nessa faixa não serão amplificadas. O projeto foi feito usando iterativamente, de maneira a otimizar os resultados obtidos, o programa de elementos finitos Msc/Nastran. Através de simulações feitas neste programa, determinamos os parâmetros geométricos ideais a serem utilizados, os quais proporcionam a maior região espectral de interesse livre de ressonâncias.

  7. On efeito do achatamento nos pontos de equilíbrio e na dinâmica de sistemas coorbitais

    NASA Astrophysics Data System (ADS)

    Mourão, D. C.; Winter, O. C.; Yokoyama, T.

    2003-08-01

    Neste trabalho analisamos o efeito do achatamento do corpo principal nos pontos de equilíbrio lagrangianos e na configuração de órbitas girino-ferradura. Enfatizamos os sistemas coorbitais de satélites de Saturno, pois se encontram em relativa proximidade com o planeta, em que o efeito do achatamento se torna mais evidente. O estudo é dividido em três etapas independentes. Na primeira fase analisamos as equações de movimento do problema restrito de três corpos considerando o efeito do achatamento, e através do balanceamento de forças buscamos a nova configuração dos pontos de equilíbrio lagrangianos. Concluímos, nesta etapa, que os pontos de equilíbrio estáveis apresentam um pequeno deslocamento definido pelo parâmetro de achatamento, não podendo ser mais representados por triângulos eqüiláteros. Aplicamos este resultado aos satélites coorbitais de Tetis e Dione, encontrando as posições de equilíbrio levemente deslocadas em relação ao caso sem achatamento. Na segunda fase visamos o sistema Saturno-Jano-Epimeteu, que por se tratar de um sistema de massas comparáveis, optamos por desenvolver as equações de Yoder et al (Icarus 53, pág 431-443, 1983), que permitem determinar os pontos de equilíbrio e a amplitude de oscilação angular das órbitas girino-ferradura para o problema não-restrito de três corpos, porém, no nosso estudo consideramos o efeito do achatamento do corpo principal nestas equações. Encontramos que a distância angular entre satélites, quando em posição de equilíbrio estável, diminui quanto maior for o parâmetro de achatamento do corpo principal. Além disso, a órbita de transição girino-ferradura possui largura angular menor em relação ao caso sem achatamento. Por fim, realizamos integrações numéricas para os casos reais de coorbitais de Saturno comparando com os resultados analíticos. Nestas integrações simulamos diversas órbitas girino-ferradura com diferentes parâmetros de achatamento, utilizando condições iniciais corrigidas para a presença do achatamento.

    This article investigates the circumstances in which Brazil’s sanitation reform was conceived and the Sistema Único de Saúde (SUS) was constructed. A brief analysis is conducted of Brazil’s political transition to democracy, focusing on three political challenges facing the consolidation of SUS: its weak support base amongst workers, competition with the private sector, and the fragmentation of its administration caused by its municipalization. Finally, the changes in the scenario caused by the weakening of neoliberalism since the 2008 crisis, the reemergence of a multipolar political scenario internationally, and the financing conditions of the Brazilian State are described.

    2004-10-01

    A study of the form and characteristics of the reservoirs and aquifers of southwestern Tunisia has been carried out from 62 petroleum explorations and hydrogeologic wells and structural maps. The evolution of basins can be deduced from the tectonic history. The Jurassic reservoirs are represented by the Upper Nara carbonates. The petrophysical characteristics and the fracturation affecting the Nara carbonates reveal the existence of very good reservoirs. Several reservoirs have also been identified in the Lower Cretaceous. These reservoirs are made of sandy levels, interbedded with shale, carbonates and dolomites. In addition, petroleum and hydrogeologic studies have revealed that potential aquifers may occur in two provinces (near the Chott Basin and east-west faults). Most of the geological formations in the South West of Tunisia are composed of sand, sandstone and limestone, with the existence of real aquifers. To cite this article: M. Chalbaoui, H. Ben Dhia, C.

    The present work is based on various filtered maps (horizontal derivative, upward continuation) and Euler deconvolution of the gravity data from northeastern Morocco. These results allow the delineation of many geological structures, such as faults, basins, or diapirs. Some of these structures are hidden totally or partially by the Mesozoic and Cenozoic cover. The results were used to make a structural map of the study area; this map confirms the existence of several faults, localised or inferred, from former geological studies. It complements information on some of them and outlines a great number of deep or near-surface faults that had remained unknown until the present time. The major features show two principal directions: N080°-085° and N055°-065°, with a predominance of the latter, and their depth can reach 4500 m. The N080°-085° directions correspond to the Kebdana, Sidi Bouhouria, Naima, and Guefait faults, and the N055°-065° directions correspond to a fault parallel to the Mediterranean coast and the Moulouya, Madagh, Angad, and Zekkara faults.

    We aim to analyze factors associated with the quality of life (QOL) response of individuals with rheumatic diseases treated by the Public Health System (Sistema Único de Saúde) with biological disease-modifying antirheumatic drugs (bDMARDs). Data from 428 patients using bDMARDs were collected using a standardized form at baseline and 6 months after the onset of treatment. The average reduction of the scores on EuroQol-five dimension was 0.11 ± 0.18 6 months after the onset of treatment with bDMARDs, denoting significant improvement of the participants' QOL. All the investigated types of disease exhibited significant improvement at the 6-month assessment, without any difference among them (p = 0.965). The participants with baseline poorest functionality and best QOL exhibited the best QOL outcomes after 6 months of treatment. Our study showed that the use of biological drugs induced considerable improvement in the participants' QOL. PMID:25603696

These constructions sometimes overlook important details and often are complicated and cumbersome. In this note, the authors propose an essential, clear and rigorous construction of R from the stucture Q+ of positive rational numbers by the key notion of initial segment.

We show that in order to ensure the random immunization or the targeted immunization effectively prevent computer viruses propagation on homogeneous networks, we should install antivirus programs in every computer node and frequently update those programs. This may produce large work and cost to install and update antivirus programs. Then we propose a new policy called "network monitors" to tackle this problem. In this policy, we only install and update antivirus programs for small number of computer nodes, namely the "network monitors". Further, the "network monitors" can monitor their neighboring nodes' behavior. This mechanism incur relative small cost to install and update antivirus programs.We also indicate that the policy of the "network monitors" is efficient to protect the network's safety. Numerical simulations confirm our analysis.

    The Antlia Cluster is the third nearest galaxy cluster after Virgo and Fornax. We used images obtained with the MOSAIC camera (36'x 36') at the 4-m CTIO telescope in the bands Kron-Cousins R and Washington C to study the globular cluster systems of the two brightest galaxies. The elliptical galaxies NGC 3258 and NGC 3268 both contain several thousand clusters (Dirsch et al. 2003). The color distributions of both systems are clearly bimodal. Their number density profiles are similar, which also applies for the red and blue cluster subpopulations. The light profile of NGC 3268 resembles that of NGC 1399, the central galaxy of the Fornax cluster. NGC 3258 has a steeper light profile at large radii. Both galaxies show color gradients, becoming bluer outwards. The globular cluster systems closely trace light profiles of their respective host galaxies in the studied radial regime. The elongation of the cluster systems is approximately aligned with an axis that connects the two galaxies. We obtain specific frequencies, within a radial range of 4', of {S}N=3.0 ±2.0 for NGC 3268 and {S}N=6.0±2.5 for NGC 3258.

  11. Coexistencia e integracion de comunicaciones inalambricas en sistemas de transmision opticos

    NASA Astrophysics Data System (ADS)

    Perez Soler, Joaquin

    Current network and telecommunication systems are required to provide higher data rates in access networks to an increasing number of users. This fact is mainly due to the increase in the Internet traffic data, which is related with the higher demand of online videogames and software, the increased complexity in the content of web pages, the joint distribution of audio-visual and added-value online content, and the introduction of high-definition services and contents such as video on demand, as a result of a society increasingly more interconnected. In order to satisfy these higher data rates requirements, new techniques for the joint distribution of several wireless communication systems are proposed in this Thesis. The aim of these techniques is to facilitate the deployment of an integrated access network at the customer premises, enabling the integration of optical transmission over an optical access network and radio-frequency transmission in the same infrastructure. Two main wireless communication systems are considered in this Thesis, WiMAX (Worldwide Interoperability for Microwave Access) and UWB (Ultra-Wide Band) according to WiMedia Alliance recommendation. Comparing the bit rate and expected range, WiMAX and UWB are complementary radio technologies expected to coexist in a near future in integrated access networks. The optical access network considered in this Thesis can be regarded as a FTTH network (Fibre-to-the-Home). The wireless signals are natively transmitted over optical network, that is, without frequency upconversion and remodulation stages, over one or several optical carriers. This technology, which is known as Radio-over-Fibre (RoF), is well suited for integrated access networks. First, the requirements for the wireless convergence of services based on Multi-Band Orthogonal-Frequency Division-Multiplexing UWB (MB-OFDM UWB) and WiMAX 802.16e in Wireless Personal Area Networks (WPAN) are stated. The aim of this study is to provide relevant protection margins in order to ensure the coexistence between both technologies. The obtained protection margins are of great interest for the development of advanced interference mitigation techniques such as DAA (Detect-and-Avoid), in the framework of future cognitive radio technologies. In a second step, the wireless coexistence of MB-OFDM UWB and WiMAX technologies is analyzed from the point of view of access networks based on RoF systems. Two experimental field trials are here carried out. In the first one, the wireless convergence is evaluated in a multi-mode fibre RoF system, whereas in the second one, the RoF system is based on a standard single-mode fibre. These experimental results provide relevant fibre link transmission distances to enable the deployment of RoF networks. Moreover, a new optical transmission technique based on polarization division multiplexing is proposed and experimentally evaluated in order to ensure the wireless coexistence in RoF systems. Finally, the impact of the electro-optical Mach-Zehnder modulator is analyzed, since the dynamic range of this device limits the performance of the RoF system. Moreover, a new optical linearization technique for Mach-Zehnder modulators is proposed and evaluated in order to overcome this limitation.

    Within the context of the return to democracy, the new constitution enacted in 1988 transformed health into an individual right and initiated the process of creating a public, universal and decentralized health system, profoundly altering the organization of public health in Brazil. This article discusses the main institutional, political and social aspects of this health reform, along with the changes, the continuities and the major initiatives, based on the literature published by the most widely read authors in this field of study. Without purporting to offer an exhaustive analysis, we discuss how the historiography written by authors who were also actors in the process assess its main features, along with the genesis of the process and the legacy of health reform in Brazil.

    We apply the two-dimensional cross-correlation technique TODCOR to derive spectroscopic orbits for the two B-type double-lined spectroscopic binaries HD 66066A and HD 315031, previously mentioned as blue straggler candidates of the open clusters NGC 2516 and NGC 6530, respectively. Reliable radial velocities for both components are measured even for orbital phases for which the separation between the spectral lines are about 0.5 times the quadratic sum of the full-width at half-maximum of the lines. Both binaries have circular orbits and the orbital periods are 1.67 and 1.38 days for HD 66066A and HD 315031, respectively. We calculate minimum masses with errors of 3-5% and obtain the projected radii from the line widths. We derive absolute stellar parameters which are consistent with the age and distance of the clusters. Both binary systems are formed by main-sequence stars and it is expected that they will experience mass-transfer between their components before the end of the core H-burning stage. HD 315031 is likely a triple system as suggested by the variation of the center-of-mass velocity.

    ``Black widow'' systems are located in a well determined region of the plane (where is the mass of the pulsar companion and is the orbital period of the system). An attempt has been made to understand which are the mechanisms that lead to companions of ``black widows'' to be located in this region; since standard binary evolution does not provide a satisfactory response. From our evolutionary calculations; we study the path performed in the plane by a binary system to reach the state of ``black widow''. We also discuss whether there is a connection between ``redbacks'' and ``black widows''. FULL TEXT IN SPANISH

  14. Cuantificacion de la radiacion de la estructura en sistemas de caja cerrada

    NASA Astrophysics Data System (ADS)

    Segura Alcaraz, Jorge G.

    In the present work a contribution to the study of the quantification of the radiation of the structure walls in systems of closed box has been made, establishing a relation of the vibroacustic response of this type of radiating systems with the characteristics of the material used, such as the Young modulus, the damping, or the density. From a general point of view, the object of the work fits within the problems of dynamic fluid-structure interaction, so the presented foundations of the procedures and models, are similar to the used in other dominions of application, like the construction, aeronautics, naval construction, Biology, etc. In order to approach the problem, a mecano-acoustic couple between the different elements from the radiating system is considered. Ideally, in the radiating systems composed of loudspeakers mounted on an acoustic enclosure or box, the walls of the box are considerated infinitely rigid with null movement. In the reality, the experience demonstrates that the walls behave like vibrant plates under the action of the inner pressures, and contribute to the final radiation of sound of the system, mainly in the low frequencies range. To obtain the proposed objective, first a series of experimental measures has been made on models of closed box with and without loudspeaker. In the experimental procedure the vibracional behavior of the walls of the structure has been studied by means of modal analysis and measures of vibration. The acoustic response of the systems is evaluated by means of measures of acoustic pressure and intensity. Next, numerical models of the loudspeaker, inner air and structure have been implemented. The implemented numerical models are mechanical-acoustic, the electrical part of the loudspeaker has been replaced by a harmonic excitation force. The first numerical model is three-dimensional, looking for obtaining a simulation of the simultaneous interaction of the three main elements of the system: the inner air of the box, the diaphragm of the loudspeaker, and the walls of the box. Moreover another numerical model in two dimensions has been implemented, adding the air outside of the box, and obtaining a fluid-structure-fluid couple. With both models a parametric study been made. In sumary the structure colors the sonorous response of the system in all the studied frequency range, due to resonances or forced vibrations of the walls. On the other hand the proposed numerical model supposes an advance with respect to the presented ones until the moment. The model constitutes a design tool that allows to study in an economic form, the importance of the structure in the sonorous response of the system.

    La expansión de la órbita del planeta Neptuno en la etapa de acreción del Sistema Solar exterior (Fernández e Ip 1984, 1996) parece ser un mecanismo eficiente para la captura de planetesimales en las resonancias exteriores con Neptuno (Malhotra 1995). Por otro lado, los estudios dinámicos realizados por varios autores indican que las resonancias son regiones de evolución estable, en contraste con el comportamiento caótico del resto de la región trans-neptuniana. Por estas razones, y si bien los datos observacionales son todavía muy limitados, se supone que los objetos descubiertos se encuentran en alguna de esas resonancias. En esta comunicación presentamos un estudio analítico y numérico de las principales resonancias exteriores con Neptuno.

    El objetivo fue identificar incentivos de atracción y retención en zonas rurales y distantes de Ayacucho, Perú. Fueron realizadas entrevistas en profundidad con 80 médicos, enfermeras, obstetras y técnicos (20 por grupo) de las zonas más pobres y con 11 funcionarios. No existen políticas sistemáticas de atracción y retención de personal de salud en Ayacucho. Los principales incentivos, en orden de importancia, fueron mejoras salariales, oportunidades de formación y capacitación, estabilidad laboral y nombramiento, mejoras en infraestructura y equipos, e incremento del personal. Se mencionaron también mejoras en la vivienda y alimentación, mayor cercanía con la familia y reconocimiento por el sistema de salud. Existen coincidencias y singularidades entre los distintos grupos sobre los incentivos clave para estimular el trabajo rural, que deben considerarse al diseñar políticas públicas. Las iniciativas del Estado deben comprender procesos rigurosos de monitoreo y evaluación, para asegurar que las mismas tengan el impacto deseado. PMID:22488318

    En los primeros años de la pasada década, un grupo de Astrónomos de La Plata iniciaron trabajos de investigación en Geodesia Satelital. En esta presentación se propone repasar sus principales logros y situarlos en el contexto del desarrollo de la disciplina a nivel mundial. Por entonces las aplicaciones prácticas de la disciplina eran indirectas y solo evidentes para los especialistas. Los errores del Posicionamiento Satelital eran de varios metros y en posicionamiento relativo, del orden de medio metro. Estos resultados se lograban al cabo de varios días de medición continuada. En los años siguientes, el sistema GPS alcanzó su nivel operacional y produjo una revolución tanto en lo relacionado con los tiempos de medición como con las precisiones. El grupo de La Plata se desarrolló simultáneamente con GPS, lo que posibilitó su participación actual en diversos temas vigentes: aplicaciones de alta precisión para la materialización de sistemas terrestres de referencia, monitoreo de movimientos de la corteza, contribución con servicios internacionales para la determinación de movimientos tectónicos globales y regionales, monitoreo de la ionósfera a partir de la propagación de las señales, determinación de la ondulación del geoide a escala local, etc. También se generaron muchas aplicaciones prácticas algunas en tiempo real: navegación, apoyo a imágenes aéreas o satelitales, aplicaciones a la agricultura, catastro y ordenamiento territorial, apoyo a relevamientos geofísicos, etc.

    En el Observatorio de Calar Alto, en Almería, España, está ubicado un telescopio de 15O-cms de diámetro -construído por REOSC- perteneciente al Observatorio Astronómico Nacional, con sede en Madrid, España. La infraestructura técnica del OAN ha sido tradicionalmente débil y actualmente se está haciendo un esfuerzo por fortalecerla. Existe una información muy limitada del telescopio en general; de su óptica en particular se conocían los valores de los parámetros principales pero sin saber si éstos corresponden a valores teóricos ó de construcción. Por ello se consideró necesario iniciar una investigación para conocer en detalle los valores reales de las componentes ópticas del telescopio, obteniéndose algunos resultados de interés. El primario del telescopio OANl5O es aproximadamente F/3 y el siste ma en su conjunto es F/8.2, con su sistema corrector de campo. En términos generales, la imagen es satisfactoria en todo el campo y, sin sistema corrector, la imagen axial también es buena. En un futuro muy cercano se piensa diseñar instrumentación adicional para este telescopio. Conocer con mayor precisión sus características puede ser de gran utilidad para tal fin, pues se efectúan los cálculos considerando conjuntamente al telescopio y al instrumento.

  9. Distributive immunization of networks against viruses using the `honey-pot' architecture

    2005-12-01

    Although computer viruses cause tremendous economic loss, defence mechanisms fail to adapt to their rapid evolution. Previous immunization strategies have been characterized as being static and centralized, which has made virus containment difficult or even impossible. We suggest, instead, to propagate the immunization agent as an epidemic. The main problem with epidemic vaccine propagation is that it is bound to lag behind the virus. We suggest giving the vaccine an advantage over the virus by allowing it to leapfrog through a separate, overlapping, partially correlated network. This enables the antivirus to contain the epidemic efficiently. We systemize this concept with a `honey-pot' architecture that achieves both early virus discovery and rapid antivirus dissemination. We present analytic, as well as simulation, results for a set of realistic topologies that illustrate the effectiveness of this approach.

    The WildList is a free list of all known computer viruses that are spreading in the world, as compiled by volunteer antivirus experts of the WildList Organization International. It is updated monthly and, as one can imagine, is quite lengthy. The site has many other interesting features besides the list. For example, a somewhat humorous article by the WildList's founder describes his views on "how scientific naming works" for computer viruses. Several other papers are also offered that deal with virus issues. Some links to sites that test products or describe viruses are given as well. This site takes a very objective approach to releasing information and, therefore, does not endorse any particular antivirus software.

  16. Código para imageamento indireto de estrelas em sistemas binarios: simulação de variações elipsoidais e do perfil das linhas

    As estrelas secundárias em variáveis cataclí smicas (VCs) e binárias-x de baixa massa (BXBMs) são cruciais para o entendimento da origem, evolução e comportamento destas binárias interagentes. Elas são estrelas magneticamente ativas submetidas a condições ambientais extremas [e.g., estão muito próximas de uma fonte quente e irradiante; têm rotação extremamente rápida e forma distorcida; estão perdendo massa a taxas de 10-8-10-10 M¤/ano] que contribuem para que suas propriedades sejam distintas das de estrelas de mesma massa na seqüência principal. Por outro lado, o padrão de irradiação na face da secundária fornece informação sobre a geometria das estruturas de acréscimo em torno da estrela primária. Assim, a obtenção de imagens da superfície destas estrelas é de grande interesse astrofísico. A Tomografia Roche usa as variações no perfil das linhas de emissão/absorção da estrela secundária em função da fase orbital para mapear a distribuição de brilho em sua superfície. Neste trabalho apresentamos os resultados iniciais do desenvolvimento de um programa para o mapeamento da distribuição de brilho na superfí cie das estrelas secundárias em VCs e BXBMs com técnicas de astro-tomografia. Presentemente temos em operação um código que simula as variações no perfil das linhas em conseqüência de efeito Doppler resultante da combinação de rotação e translação de uma estrela em forma de lobo de Roche em torno do centro de massa da binária, em função da distribuição de brilho na superfície desta estrela. O código igualmente produz a curva de luz resultante das variações de aspecto da estrela em função da fase orbital (variações elipsoidais).
