description: We consider variants of dimensional regularization, including the four-dimensional helicity scheme (FDH) and dimensional reduction (DRED), and present the gluon and quark form factors in the FDH scheme at next-to-next-to-leading order. We also discuss the generalization of the infrared factorization formula to FDH and DRED. This allows us to extract the cusp anomalous dimension as well as the quark and gluon anomalous dimensions at next-to-next-to-leading order in the FDH and DRED scheme, using $\overline{\text{MS}}$ and $\overline{\text{DR}}$ renormalization. To obtain these results we also present the renormalization procedure in these schemes.

description: In order to find a fast and reliable method for selecting metal poor galaxies (MPGs), especially in large surveys and huge database, an Artificial Neural Network (ANN) method is applied to a sample of star-forming galaxies from the Sloan Digital Sky Survey (SDSS) data release 9 (DR9) provided by the Max Planck Institute and the Johns Hopkins University (MPA/JHU). A two-step approach is adopted:(i) The ANN network must be trained with a subset of objects that are known to be either MPGs or MRGs(Metal Rich galaxies), treating the strong emission line flux measurements as input feature vectors in an n-dimensional space, where n is the number of strong emission line flux ratios. (ii) After the network is trained on a sample of star-forming galaxies, remaining galaxies are classified in the automatic test analysis as either MPGs or MRGs. We consider several random divisions of the data into training and testing sets: for instance, for our sample, a total of 70 percent of the data are involved in training the algorithm, 15 percent are involved in validating the algorithm and the remaining 15 percent are used for blind testing of the resulting classifier. For target selection, we have achieved an acquisition rate for MPGs of 96 percent and 92 percent for an MPGs threshold of 12+log(O/H)=8.00 and 12+log(O/H)=8.39, respectively. Running the code takes minutes in most cases under the Matlab 2013a software environment. The ANN method can easily be extended to any MPGs target selection task when the physical property of the target can be expressed as a quantitative variable.

description: This paper investigates the collider phenomenolgy of a minimal nonthermal dark matter model with a 1-GeV dark matter candidate, which naturally explain baryongensis. Since the light dark matter is not parity-protected, it can be singly produced at the LHC. This leads to large missing energy associated with an energetic jet whose transverse momentum distribution is featured by a Jacobian-like shape. The monojet, dijet, paired dijet and 2 jets + missing energy channels are studied. Currently existing data at Tevatron and LHC offer significant bounds on our model.

description: We consider explicit unified models based on the flipped ${SU(5)\times U(1)}$ and $SU(6)\times SU(2)$ gauge groups in which gauge mediated proton decay operators are suppressed at leading order due to the special placement of matter fields in unified multiplets. We discuss both the theoretical structure and phenomenological implications of these models. For the latter, we examine the viability of the physical spectrum in each scenario and focus on the possible presence of other operators that could also contribute significantly to the proton decay rate.

description: We study the complete tunneling spectroscopy of a normal metal/$p$-wave superconductor junction ($N-pS$) and normal metal/heterostructure superconductor junction ($N-hS$) by Blonder-Tinkham-Klapwijk (BTK) method. We find that, for $p$-wave superconductor with non-trivial topology, there exists a quantized zero-bias conductance peak stably, for heterostructure superconductor with non-trivial topology, the emerging zero-bias conductance peak is non-quantized and usually has a considerable gap to the quantized value. Furthermore, it is sensitive to parameters, especially to spin-orbit coupling and the $s$-wave pairing potential. Results obtained suggest that the observation of a small zero-bias conductance peak, instead of a quantized zero-bias conductance peak, in current tunneling experiments can be a natural result if the spin-orbit coupling turns out to be several times smaller than the reported one. Results obtained also suggest that both a stronger spin-orbit coupling and proximity $s$-wave superconductor with relative weaker pairing potential can produce a much more striking zero-bias conductance peak (compared to the experiments), even an almost quantized one. As $s$-wave superconductors are common in nature, the prediction can be verified within current experiment ability.

description: Intense X-ray photo-absorption from short and intense pulses by a molecule triggers complicated electron and subsequently ion dynamics leading to photo-electron spectra which are difficult to interpret. Illuminating fullerenes offers a way to separate out the electron dynamics. Moreover, the fullerene cage confines spatially the origin of photo and Auger electrons. Together with the sequential nature of the photo processes at intensities available at X-ray free electron lasers, this allows for a remarkably detailed interpretation of the photo-electron spectra as we will demonstrate. The general features derived can serve as a paradigm for less well-defined situations in other large molecules or clusters.

description: This study investigates the role of the client isolation technology Public Secure Packet Forwarding (PSPF) in defending 802.11 wireless (Wi-Fi) clients, connected to a public wireless access point, from Address Resolution Protocol (ARP)cache poisoning attacks, or ARP spoofing. Exploitation of wireless attack vectors such as these have been on the rise and some have made national and international news. Although client isolation technologies are common place in most wireless access points, they are rarely enabled by default. Since an average user generally has a limited understanding of IP networking concepts, it is rarely enabled during access point configurations. Isolating wireless clients from one another on unencrypted wireless networks is a simple and potentially effective way of protection. The purpose of this research is to determine if a commonly available and easily implementable wireless client isolation security technology, such as PSPF, is an effective method for defending wireless clients against attacks.

Generating buoyant magnetic flux ropes in solar-like convective dynamos

description: Our Sun exhibits strong convective dynamo action which results in magnetic flux bundles emerging through the stellar surface as magnetic spots. Global-scale dynamo action is believed to generate large-scale magnetic structures in the deep solar interior through the interplay of convection, rotation, and shear. Portions of these large-scale magnetic structures are then believed to rise through the convective layer, forming magnetic loops which then pierce the photosphere as sunspot pairs. Previous global simulations of 3D MHD convection in rotating spherical shells have demonstrated mechanisms whereby large-scale magnetic wreaths can be generated in the bulk of the convection zone. Our recent simulations have achieved sufficiently high levels of turbulence to permit portions of these wreaths to become magnetically buoyant and rise through the simulated convective layer through a combination of magnetic buoyancy and advection by convective giant cells. These buoyant magnetic loops are created in the bulk of the convective layer as strong Lorentz force feedback in the cores of the magnetic wreaths dampen small-scale convective motions, permitting the amplification of local magnetic energies to over 100 times the local kinetic energy. While the magnetic wreaths are largely generated the shearing of axisymmetric poloidal magnetic fields by axisymmetric rotational shear (the $Ω$-effect), the loops are amplified to their peak field strengths before beginning to rise by non-axisymmetric processes. This further extends and enhances a new paradigm for the generation of emergent magnetic flux bundles, which we term turbulence-enabled magnetic buoyancy.

description: Structural analyses of modified wing structures are performed to achieve nonlinear progressive tip twisting behaviour for passive load reduction by exploiting buckling of selected components. In this paper, wing box segments with a previously developed design concept are integrated into a full three-dimensional finite element model of the wing. Parametric analyses are performed to find a good design and corresponding sensitivities. The result is a wing design for future aeroelastic analysis that utilizes the modified wing box segments to induce additional wing twisting, potentially improving the load reduction behaviour above a critical load compared to a conventional design.

description: Abaca farming is one of the major sources of income of farmers living in the four barangays of Manito, Albay consist of Balasbas, Buyo, Cawayan and Nagotgot. Unfortunately, this livelihood is threatened by the spread of abaca diseases such as abaca bunchy top, bract mosaic, and abaca mosaic which the mosaic has been one of the major factors contributing in decreased crop productivity. This study evaluates the effectiveness of the Abaca Disease Management Project of Philippine Fiber Industry Development Authority in Manito, Albay based from the gathered secondary data and field interviews. The socio-demographic profile of the respondents was gathered to understand its correlation on farmer’s perception whether the project is effective or not. The impacts of the project are discussed specifically the socio-economic, gender equality, social capital and other impacts. Out of 125 farmer-beneficiaries, 57 abaca farmers were interviewed. It was found that the ADMP conducted by PhilFIDA in Manito, Albay was effective in controlling and eradicating abaca diseases. Majority of farmers interviewed believed that ADMP was successful. The major contribution of the project to the farmer’s household increased in fiber harvested, families enabled to send their children to school and abaca farming became their major source of income. Women had equal chance to participate in community organizations. The number of farmer-beneficiaries attending the training and skill development like training on abaca disease control and eradication and livelihood training on abaca fiber processing increased. Respondent’s role in abaca farming had high and middle degree of correlation to the increase of abaca fiber harvested, also to the perceived success of the project. Increase in abaca fiber harvested by the farmers had positive correlation to their perception that ADMP would be a successful project. However, the status of ownership of the land being cultivated, the size of the farm, the age, the sex, the civil status, the education, and the number of children of the farmers had no correlation to the increase of abaca fiber harvested and to the farmer’s perception on the success of the project. Results of the study could be valuable for the implementing agency and local government unit in reviewing their project implementation, management and policy-making.

description: The bending of cilia and flagella is driven by forces generated by dynein motor proteins. These forces slide adjacent microtubule doublets within the axoneme, the motile cytoskeletal structure. To create regular, oscilla- tory beating patterns, the activities of the axonemal dyneins must be coordinated both spatially and temporally. It is thought that coordination is mediated by stresses or strains, which build up within the moving axoneme, and somehow regulate dynein activity. While experimenting with axonemes subjected to mild proteolysis, we observed pairs of doublets associate with each other and form bends with almost constant curvature. By model- ing the statics of a pair of filaments, we show that the activity of the motors concentrates at the distal tips of the doublets. Furthermore, we show that this distribution of motor activity accords with models in which curvature, or curvature-induced normal forces, regulates the activity of the motors. These observations, together with our theoretical analysis, provide evidence that dynein activity can be regulated by curvature or normal forces, which may, therefore, play a role in coordinating the beating of cilia and flagella.

The virtual pilot is a mathematical model of the behaviour of a trained human involved in a vehicle piloting task. These models are fundamental to perform closed-loop simulations. The models presented here are divided into frequencybased and time-based, and for each of them advantages and disadvantages are discussed in order to help the reader select a suitable model for a given task. The time-based models are found to be more adaptable and suitable for online characterization, while the frequency-based are easier to tune, but offiine.

description: Single walled carbon nanotube's cross section can be flattened under hydrostatic pressure. One example is the cross section of a single walled carbon nanotube successively deforms from the original round shape to oval shape, then to peanut-like shape. At the transition point of reversible deformation between convex shape and concave shape, the side wall of nanotube is flattest. This flattest tube has many attractive properties. In the present work, an approximate approach is developed to determine the equilibrium shape of this unstrained flattest tube and the curvature distribution of this tube. Our results are in good agreement with recent numerical results, and can be applied to the study of pressure controlled electric properties of single walled carbon nanotubes. The present method can also be used to study other deformed inorganic and organic tube-like structures.

description: We study laser cooling of atomic gases by collisional redistribution of fluorescence. In a high pressure buffer gas regime, frequent collisions perturb the energy levels of alkali atoms, which allows for the absorption of a far red detuned irradiated laser beam. Subsequent spontaneous decay occurs close to the unperturbed resonance frequency, leading to a cooling of the dense gas mixture by redistribution of fluorescence. Thermal deflection spectroscopy indicates large relative temperature changes down to and even below room temperature starting from an initial cell temperature near 700 K. We are currently performing a detailed analysis of the temperature distribution in the cell. As we expect this cooling technique to work also for molecular-noble gas mixtures, we also present initial spectroscopic experiments on alkali-dimers in a dense buffer gas surrounding.

description: Spacecraft entering a planetary atmosphere are surrounded by a plasma layer containing high levels of ionization. The high electron number densities cause attenuation and rotation of the polarization of the emitted signal, leading to communication blackout. This work presents experimental measurements of radio signal attenuation and Faraday rotation due to an ionized plasma flow. These measurements are conducted at the VKI Plasmatron using circularly polarized directive horn lens antennas with a waveguide orthomode transducer. Clear attenuations are observed when the signal is propagating through the plasma, and Faraday rotation measurements show a good agreement with the theoretical estimation. Additionally, the jet temperature and electron number density distributions are experimentally measured with emission spectroscopy, and these results show a good agreement with numerical estimations. Overall, the signal propagation results comply with the temperature and electron density measurements.

description: Virtualization is a very popular solution to many problems in datacenter management. It offers increased utilization of existing system resources through effective consolidation, negating the need for more servers and additional rack space. Furthermore, it offers essential capabilities in terms of disaster recovery and potential savings on energy and maintenance costs. However, these benefits may be tempered by the increased complexities of securing virtual infrastructure. Do the benefits of virtualization outweigh the risks? In this study, the authors evaluated the functionalities of the basic components of virtual datacenters, identified the major risks to the data infrastructure, and present here several solutions for overcoming potential threats to virtual infrastructure.

description: Low-pressure turbines (LPT) are subject to laminar flow separation when operating on a low-Reynolds regime. To study the dynamics and instability properties of the separated shear layer in response to harmonic forcing inflow conditions and flow actuation with zero-net-mass-flux (ZNMF), a series of direct numerical simulations are performed. Under unsteady inflow conditions, the change in bulk velocity triggers an early transition and is capable of reducing the length of the mean recirculation bubble. In the ZNMF actuation, results suggest that actuation based on the excitation of the -local-KH instability can be less effective in reducing the extent of the separated flow than alternative strategies addressing the global dynamics of the recirculation region.

description: We develop a mean-field approach for multicomponent stochastic spatially extended systems and use it to obtain a multivariate nonlinear self-consistent Fokker-Planck equation defining the probability density of the state of the system, which describes a well-known model of autocatalytic chemical reaction (brusselator) with spatially correlated multiplicative noise, and to study the evolution of probability density and statistical characteristics of the system in the process of spatial pattern formation. We propose the finite-difference method for numerical solving of a general class of multivariate nonlinear self-consistent time-dependent Fokker-Planck equations. We illustrate the accuracy and reliability of the method. Numerical study of the nonlinear self-consistent Fokker-Planck equation solutions for a stochastic brusselator shows that in the region of Turing bifurcation several types of solutions exist if noise intensity increases: unimodal solution, transient bimodality, and an interesting solution which involves multiple repumping of probability density through bimodality. Additionally we study the behavior of the order parameter of the system under consideration and show that the second type of solution arises in the supercritical region if noise intensity values are close to the values appropriate for the transition from bimodal stationary probability density for the order parameter to the unimodal one.

description: Transitions to high mass accretion rates in black hole X-ray binaries are associated with the ejection of powerful, relativistically-moving jets. The mechanism powering such events is thought to be linked to tapping of the angular momentum (spin) of the black hole, the rate of accretion through the disc or some combination of the two. We can attempt to discriminate between these possibilities by comparing proxies for jet power with spin estimates. Due to the small number of sources reaching Eddington rates and have therefore been suggested to act as 'standard candles', there has been much recent debate as to whether a significant correlation exists between jet power and spin. We perform continuum fitting to the high-quality, disc-dominated XMM-Newton spectra of the extragalactic microquasar discovered in M31. Assuming prograde spin, we find that, for sensible constraints the spin is always very low (a < 0.15 at 3-sigma). When combined with a proxy for jet power derived from the maximum 5 GHz radio luminosity during a bright flaring event, we find that the source sits well above the previously reported, rising correlation that would indicate that spin tapping is the dominant mechanism for powering the jets. The notable exceptions require the inclination to be improbably small or the jet to be very fast. We investigate whether this could be a by-product of selecting prograde-only spin, finding that the data statistically favour a substantially retrograde spin for the same constraints (a < -0.17 at 3-sigma). Although theoretically improbable, this remarkable finding could be confirmation that retrograde spin can power such jets via spin-tapping, as has been suggested for certain radio quasars. In either case this work demonstrates the value of studying local extragalactic microquasars as a means to better understand the physics of jet launching.

description: One of the key security threats on the Internet are the compromised machines that can be used to launch various security attacks such as spamming and spreading malware, accessing useful information and DDoS. Attackers for spamming activity are volunteer by large number of compromised machines. Our main focus is on detection of the compromised machines in a network that may be or are involved in the spamming activities; these machines are commonly known as spam zombies. Activities such as port scan, DB scan and so on are treated as malicious activity within the network. So to overcome that we develop one of the most effective spam zombie detection system within the network based on the behavior of other systems as if performing the above activities are treated as zombies machines. If any system within the network try's to gather some information about any other system then this is treated as a malicious activity and should be not allowed to do so. SYN packets are used in order to initiate communication within the network so as to establish connection. If any system try's to flood the network with these packets we can make an assumption that the system is trying to gather the information about other system. This is what called footprinting. So we will try to detect any system involved in footprinting and report to the administrator.

description: Air transport contribution to annual anthropogenic CO2 emissions is evaluated at 2.6%, as well as additional climate impacts. In order to assess the future environmental impacts of air transport, the AeroMAPS open-source framework was previously developed for simulating prospective scenarios, including a specific module to evaluate the costs of alternative fuels. This paper presents additional cost models to evaluate the direct operating cost at the fleet level, as well as the manufacturing non-recurring and recurring costs. The potential role played by regulatory measures for aviation decarbonization is assessed, considering two examples. First, the consequences of setting low-carbon fuels blending mandates are investigated, and options available to design them are reviewed, highlighting the need to find a compromise between deep decarbonization over time and economic efficiency. Secondly, setting stringent aircraft energy intensity rules can be used to ensure the fleet is renewed at the right moment to respect a given cumulative CO2 emissions target, or other objectives. An illustrative example shows the interest of an early introduction of a given new aircraft type.

Quantum Jumps Are More Quantum Than Quantum Diffusion

description: It was recently argued [Phys. Rev. Lett 108, 220402 (2012)] that the stochastic dynamics of an open quantum system are not inherent to the system, but rather depend on the existence and nature of a distant detector. The proposed experimental tests involved homodyne detection, giving rise to quantum diffusion, and required total efficiencies of well over 50%. Here we prove that for no system is it possible to demonstrate detector-dependence using diffusive-type detection of efficiency less than 50%. However, this no-go theorem does not apply to quantum jumps, and we propose a test involving a qubit, using different jump-type detectors, with a threshold efficiency of only 37%.

description: In the debate on international waste trade, the focus on resource efficiency and recycling has gradually begun to accompany the focus on negative environmental externalities. In this context, we examine the impact of Extended Producer Responsibility (EPR) on the export of waste batteries (WB). EPR is considered as a key policy for the “marketization of waste”. On the other hand, WB are a hazardous waste that also contain a high concentration of critical raw materials. As such, they are of strategic importance for the recovery of critical resources, while at the same time requiring proper environmental management. Therefore, it is crucial to understand where WB are treated and how this is affected by related policies. Our results, based on difference-in-difference models in a gravity framework, show a consistent increase in WB exports after EPR implementation compared to the trend for other wastes. This result is likely to be an indirect consequence of the ability of EPR to support growth in waste collection rates, more accurate tracking of transboundary waste flows, and specialization of national waste management systems. In particular, EPR exports appear to be directed to countries with more advanced waste management systems rather than to developing countries.

description: New manufacturing methods such as 3D-printing enable more complex geometries for Solid Rocket Motors (SRM). With complex shapes and multiple different solid fuels, it is possible to create an application tailored thrust curve of an SRM. Since additive manufacturing methods are slow, modelbased predictions can help developing novel SRMs. These models enable SRM geometry testing and optimization. Such models need to be able to describe both the surface regression of the burning surface and the internal ballistics in the combustion chamber. In previous models the internal ballistics of the SRJ\\1 were often solved in zero-or one-dimensional models [1]. For complex geometries multidimensional model sensible, due to erosive effects and local pressure differences, which can affect the combustion rate. To model these effects the flow inside the combustion chamber needs to be solved with a model with the same number of dimensions as the surface regression model. An accurate description of the surface regression is essential since the burned surface directly influences the mass flux thus the pressure in the combustion chamber. Furthermore, the combustion rate of solid rocket fuels is dependent on the pressure in the combustion chamber. The Level-Set-Method has been used in the past to describe the geometric changes of the burning surface during the of an SRM [1]. Previous models were however unable to describe the surface regression for SRM using multiple different types of solid fuel burning at the same time. This issue is caused by the usual assumption of a homogenous combustion rate on the burning surface, to reduce computational cost. The model described here, reconstructs the surface out of the implicit information of the Singed-Distance-Function of the Level-Set-Method and computes the local combustion rate for each surface element. The model described here combines a surface regression model for heterogenous SRMs with a computational fluid dynamics (CDF) model for the internal ballistics. This allows for the test and optimization of possible SRM geometries.

description: In this paper, the exact analytical solution of the Susceptible-Infected-Recovered (SIR) epidemic model is obtained in a parametric form. By using the exact solution we investigate some explicit models corresponding to fixed values of the parameters, and show that the numerical solution reproduces exactly the analytical solution. We also show that the generalization of the SIR model, including births and deaths, described by a nonlinear system of differential equations, can be reduced to an Abel type equation. The reduction of the complex SIR model with vital dynamics to an Abel type equation can greatly simplify the analysis of its properties. The general solution of the Abel equation is obtained by using a perturbative approach, in a power series form, and it is shown that the general solution of the SIR model with vital dynamics can be represented in an exact parametric form.

description: The effects of cold fuel outflow from secondary nozzles in bleed engine and gas generator cycles on the heat flux distribution along the the baseplate of a reusable launch vehicle are generally ignored in research on launch vehicles. In this work we address this question with numerical simulations of the flowfield. We compare configurations with and without secondary nozzle outflows and show that the predicted thermal loads in the observed region of the vehicle are significantly reduced due to an entertainment of the secondary nozzle flow. We furthermore investigate the differences between a bleed nozzle configuration and a gas generator configuration and we analyse the behaviour over different points of the ascent trajectory of the vehicle. Our work demonstrates the importance of including secondary nozzles in heat flux predictions for launchers.
