description: This article contributes to the growing body of literature on opposition coordination within competitive authoritarian regimes (CARs). Defining oppositional unity as the ability of key opposition parties to select one joint candidate for elections, it introduces the concept of an intermediary party that facilitates such unity. An intermediary party is perceived less threatening by other opposition parties in their opportunistic and ideological conflicts and has the potential to offer a more agreeable joint candidate or a more conciliatory method of selecting the joint candidate within the opposition bloc. The article illustrates this argument by examining the Budapest and Istanbul mayoral elections held in 2019 in Hungary and Turkey. Drawing on data from 30 anonymized elite interviews and media statements of the opposition leaders in each country, the article demonstrates the significance of an intermediary party that facilitates oppositional unity in CARs, adding that the participation of intraparty actors with strong communication skills during the negotiations further reinforces this outcome.

description: We perform a comparative study of AGNs in pairs, triplets and groups. To this end we use the Duplancic et al. catalogue of small galaxy systems and consider BPT and WHAN diagnostic diagrams to select optical AGNs. Also we identify mid-IR AGNs by using WISE data. We performed a comparison between the different AGN classification methodologies and study the AGN fraction in pairs, triplets, and groups with four to six members. We also analyse the main properties of Optical and mid-IR AGN hosts and the influence of environment on the active nuclei phenomena in these small galaxy systems. Our results show that, regardless the specifically adopted classification scheme, the fraction of AGN in pairs and triplets is always higher than the corresponding fraction in groups. Moreover, the fraction of powerful AGNs in pair and triplets is about twice the fraction of regular AGNs. We also find a remarkable difference between Optical and mid-IR AGNs in groups, where host galaxies of WISE AGNs are less massive and concentrated, with young stellar populations and blue colours. Also all WISE AGNs in groups have a very close companions and reside in an intermediate global density environment. Galaxy triplets show a larger AGN fraction for galaxies with a close nearest neighbours, while pairs present a nearly constant AGN fraction regardless the distance to the nearest companion. Our studies highlight the important role of interactions, besides the global environment dependence, in the activation of the AGN phenomenon in small galaxy systems.

Year: 2019

Technical Session
In modern power grids there is already a significant penetration of renewable energy sources installed at both transmission and distribution systems. The degree of penetration is likely to grow much higher in the future. The response of inverter interfaced or controlled generation to faults is significantly different compared to that of conventional rotating machines. The integration of large amounts of distributed generation to distribution systems causes bidirectional power flows making conventional distribution systems protection schemes ineffective. In this panel, experts in power systems protection will discuss the research challenges and some potential state-of-the-art solutions for protecting power transmission and distribution systems with massive amounts of renewable energy.

2019 IEEE General Meeting 8/7 Panel Presentation: Cybersecurity and Resiliency for the Power Grid Leveraging Data-Driven Models and Analytics
In recent years, cyber threats to the power grid has been growing both in numbers and sophistication, including two attacks on Ukrainian power grid and several attack attempts targeted towards energy and other critical infrastructures around the world. While data analytics and machine learning techniques have fostered many social, economic, and business advances; they also introduce potential solutions to many current grid cybersecurity challenges. Moreover, the adoption of data-driven models, algorithms, and tools has been gaining momentum for energy management system (EMS) and market applications in the utility industry. Although there are potentially significant benefits from the adoption of data-driven models, algorithms, and applications for the power grid, there are several challenges that need to be addressed, namely, the quality of the data and robust datasets for training, the nature of the models, the effectiveness of the machine learning algorithms, and more importantly the compelling applications that can benefit from such data analytics. The goal of this panel is to discuss the opportunities and challenges associated with data-driven analytics for cybersecurity and resiliency of the grid, and also showcase sample case studies of successful applications and tools. The panel will bring international experts both from academia and industry/government laboratories to have a broad discussion on the practical insights into data-driven analytics and articulate potential R&D directions in cybersecurity and resiliency of the power grid.

description: Articular cartilage lesions, with their inherent limited healing potential, are hard to treat and remain a challenging problem for orthopedic surgeons. Despite the development of several treatment strategies, the real potential of each procedure in terms of clinical benefit and effects on the joint degeneration processes is not clear.
Aim of this PhD project was to evaluate the results, both in terms of clinical and imaging improvement, of new promising procedures developed to address the challenging cartilage pathology. Several studies have been followed in parallel and completed over the 3-year PhD, and are reported in detail in the following pages. In particular, the studies have been focused on the evaluation of the treatment indications of a scaffold based autologous chondrocyte implantation procedure, documenting its results for the classic indication of focal traumatic lesions, as well as its use for the treatment of more challenging patients, older, with degenerative lesions, or even as salvage procedure for more advanced stages of articular degeneration. The second field of study involved the analysis of the results obtained treating lesions of the articular surface with a new biomimetic osteochondral scaffold, which showed promise for the treatment of defects where the entire osteochondral unit is involved. Finally, a new minimally invasive procedure based on the use of growth factors derived from autologous platelets has been explored, showing results and underlining indicatios for the treatment of cartilage lesions and different stages of joint degeneration.
These studies shed some light on the potential of the evaluated procedures, underlining good results as well as limits, they give some indications on the most appropriate candidates for their application, and document the current knowledge on cartilage treatment procedures suggesting the limitations that need to be addressed by future studies to improve the management of cartilage lesions.

description: We analytically derive a decomposition of the lattice fermion determinant for Wilson's Dirac operator with chemical potential into winding sectors, i.e., factors with a fixed number of quarks. Dividing the lattice into four domains, the determinant is factorized into terms which can be classified with respect to the winding number of the closed loops they consist of. The individual factors are expressed in terms of subdeterminants and propagators on the domains of the lattice. We numerically analyze properties of the factorization formula and discuss two applications for the determination of canonical partition functions with a fixed quark number: A speedup for the Fourier transformation technique through a dimensional reduction, and a power series expansion.

Technical Session
In the currently active revision of IEEE 1782, there are ten outage categories used for macro level benchmarking to provide a starting point for utilities looking to establish methods for tracking reliability through outage cause codes. In recognition of the need for more granular benchmarking to better grasp industry trends, the Distribution Reliability Working Group has developed a set of subcategories to enhance the ten categories currently used. This panel session will share the expanded subcategories to be balloted in the next revision of the 1782 guide to a broader audience and present how utilities plan to incorporate the new subcategories into existing outage cause code collection procedures.
First detection of C$_2$H$_5$NCO in the ISM and search of other isocyanates towards the G+0.693-0.027 molecular cloud

description: Little is known about the chemistry of isocyanates (compounds with the functional group R-N=C=O) in the interstellar medium, as only four of them have been detected so far: isocyanate radical (NCO), isocyanic acid (HNCO), N-protonated isocyanic acid (H$_2$NCO$^+$) and methyl isocyanate (CH$_3$NCO). The molecular cloud G+0.693-0.027, located in the Galactic Centre, represents an excellent candidate to search for new isocyanates since it exhibits high abundances of the simplest ones, HNCO and CH$_3$NCO. After CH$_3$NCO, the next complex isocyanates are ethyl isocyanate (C$_2$H$_5$NCO) and vinyl isocyanate (C$_2$H$_3$NCO). Their detection in the ISM would enhance our understanding of the formation of these compounds in space. We have detected C$_2$H$_5$NCO and H$_2$NCO$^+$ towards G+0.693-0.027 (the former for the first time in the interstellar medium) with molecular abundances of (4.7$-$7.3)$\times$10$^{-11}$ and (1.0$-$1.5)$\times$10$^{-11}$, respectively. A ratio CH$_3$NCO / C$_2$H$_5$NCO = 8$\pm$1 is obtained; therefore the relative abundance determined for HNCO:CH$_3$NCO:C$_2$H$_5$NCO is 1:1/55:1/447, which implies a decrease by more than one order of magnitude going progressively from HNCO to CH$_3$NCO and to C$_2$H$_5$NCO. This is similar to what has been found for e.g. alcohols and thiols and suggests that C$_2$H$_5$NCO is likely formed on the surface of dust grains. In addition, we have obtained column density ratios of HNCO / NCO > 269, HNCO / H$_2$NCO$^+$ $\sim$ 2100 and C$_2$H$_3$NCO / C$_2$H$_5$NCO~

IMPLEMENTATION OF SCREENING, BRIEF INTERVENTIONS, AND REFERRAL TO TREATMENT (SBIRT) IN THE EMERGENCY DEPARTMENT

Publisher: name: Zenodo
Year: 2018

description: Drug and alcohol use is an epidemic health problem that is affecting Americans at an unprecedented scale. The federal government, states governments, and local authorities across the United States are working together to fight this epidemic. The Screening, Brief Intervention, and Referral to Treatment (SBIRT) initiative was introduced in 2003 by the Substance Abuse and Mental Health Services Administration (SAMHSA). The program goal was to leverage any interaction time between patients and healthcare providers for any health complaint to screen for drug and alcohol use, provide brief interventions, and to appropriately refer individuals to substance rehabilitation treatment. The program was intended to be used in different healthcare facilities including primary care, counseling centers, inpatient units, behavioral health units, and emergency departments. In this scholarly project, Screening, Brief Intervention, and Referral to Treatment SBIRT was implemented in the Emergency Care Center (ECC) of St. Joseph HospitalOrange. The goal was to integrate screening of all ECC eligible patients (18-65 years of age) for drug or alcohol use in the care process. The project involved implementing SBIRT as a standard of practice in the ECC and required training ECC nurses to provide SBIRT interventions. Evaluation occurred after six weeks of launching the program. Of iv the patients visiting the ECC, 3.5% received a SBIRT intervention. The validated evaluation tool Confidence Scale (C-scale) by Susan Grundy (1993) was utilized to evaluate training efficacy. Nurse knowledge of SBIRT increased with training. A paired sample t-test revealed a statistically significant difference between the total scores of the C-scale pre-test (M = 7.82, SD = 4.13) and immediate post-test (M = 16.81, SD = 3.7), t (86) = 17.6, p < .001) and a statistically significant difference across the five items of the C-scale between pre-training and post-training of the 87 participants who completed the tool. The number of patients receiving SBIRT interventions is expected to increase in context with the planned change of the current EMR system at St. Joseph Hospital to a more adaptive system. Future clinicians and hospital administrators who anticipate implementing SBIRT may wish to consider customizing the EMR to include a userfriendly screening and documentation templates of SBIRT interventions. Challenges that emerged during the implementation process included the lack of technical capabilities of the ECC current EMR to include SBIRT intervention and the difficulty of achieving optimal face-to-face interaction between the project leader and all 125 nurses in the ECC.

description: The intrinsic double helix conformation of the DNA strands is known to be the key ingredient of control of the electric current through the DNA by the perpendicular (gate) electric field. We show theoretically that Bloch oscillations in the DNA are also strongly affected by such lateral field; the oscillation frequency splits into a manifold of several generally non-commensurate frequencies leading to a complicated pattern of the charge motion. The frequency of the oscillations falls in the THz domain, providing for a possibility to design a nano-scale source of THz radiation.

description: Malaysia’s fifteenth general election (GE15) was a milestone in the country’s democratization process, with three major coalitions contesting for national power after years of political instability. In this article, we investigate how Malaysia’s cleavage structure – a central feature of Malaysia’s prior authoritarian regime – shapes electoral competition in a newly competitive political environment. We find that the ethnic structure remains central to explaining party strategy and coalition behaviour in GE15, but that more democratic competition has increased the salience of regional differences – both between peninsular Malaysia and East Malaysia, and within peninsular Malaysia itself. Our analysis reveals the structural foundations of political competition in democratizing countries and contribute to the emerging literature on authoritarian legacies in such contexts.

description: We present an extension of the velocity-dependent one-scale model for cosmic string evolution, which is suitable for describing the evolution of local and global monopole networks. We discuss the key dynamical features that need to be accounted for, in particular the fact that the driving force is due to the other monopoles (rather than being due to local curvature as in the case of extended objects) and new forms of energy loss terms due to monopole-antimonopole capture and annihilation. For the case of local monopoles we recover and generalize the results of Preskill, suggesting that the scaling law for the monopole correlation length is very sensitive to the annihilation rate. On the other hand, for global monopoles the long-range forces generically lead to linear scaling (just like in the case of local cosmic strings). In this case we also find good qualitative agreement between our results and the numerical simulations of Bennett & Rhie and Yamaguchi, although future high-resolution simulations will be needed for quantitative comparisons.

A Global Energy Internet (EI) integrates all forms of energy based on information flow via the Internet.  In January 2011, the Energy Internet was described in the Proceedings of the IEEE. In July 2014, Energy production and consumption have kept increasing as economies grow. The large-scale development and utilization of fossil energy has resulted in serious problems such as resource shortage, environmental pollution and climate change. Energy internet is among the few major technological development areas for energy and the next generation ICT technologies. It is the next level of smart grid technology aiming for more renewable penetrations and greater prosumer participation. In this panel, speakers from different countries will talk about their experience and good practices in this area and also future trend.

Observation of two-photon emission after pion capture in carbon-12
Creators: name: Mazzucato, Eddy
Publisher: name: University of British Columbia
Year: 2010

description: The ¹²C(π⁻,2γ)X reaction for stopped pions has been investigated at TRIUMF using two large Nal crystals (TINA and MINA) and two lead glass Cerenkov counters. A 20 MeV pion beam from the stopped π /μ channel (M9) was used. The incoming pion beam was defined by a 3-counter telescope (S₁,S₂,S₃) and was stopped in a 1.25 cm thick carbon target. The last telescope counter (S₃) determined the time of arrival of the pions. The four γ-detectors were located at +55°, +105°, -55°, and -135°, with respect to the incident pion beam. Scintillation counters were placed in front of each γ-detector in order to identify charged particles. For the Nal crystals, time-of-flight information was used to separate neutrons and gammas originating from the (π⁻,nn) and (π⁻,nγ) reactions. Accidental coincidences from simultaneous (π⁻,γ) reactions generated by multiple pion stops in the target were rejected by measuring the energy deposited by the incoming pions in S₃. A total of 2.5x10¹¹ pions were stopped, and after background subtraction, about 500 good events were observed at 6 different opening angles (θ[sub γγ] = 50°, 80°, 110°, 120°, 160°, 170°). The total branching ratio for the ¹²C(π⁻,2γ) reaction was measured to be (1.2 ± 0.2)x0⁻⁵; this value was found to be very sensitive to the low-energy threshold of the Y~detectors. The good energy resolution (=10%) of the Nal crystals permitted the investigation of the energy-sharing between the two photons at θ[sub γγ] = 120°. The sum energy spectrum of the two photons peaks at 120 MeV i and has a width of about 40 MeV. Its shape indicates that most of the available energy is carried off by the two photons and that the residual nucleus, most likely ¹²B, is not highly excited. Detailed theoretical calculations made by other authors predict a total 2γ rate approximately 30% larger than our measured value. No evidence for pion condensates or precondensate effects in ¹²C was found.
Coherent soliton states hidden in phase-space and stabilized by gravitational incoherent structures

description: We consider the problem of the formation of soliton states from a modulationally unstable initial condition in the framework of the Schrödinger-Poisson (or Newton-Schrödinger) equation accounting for gravitational interactions. We unveil a previously unrecognized regime: By increasing the nonlinearity, the system self-organizes into an incoherent localized structure that contains "hidden" coherent soliton states. The solitons are "hidden" in the sense that they are fully immersed in random wave fluctuations: The radius of the soliton is much larger than the correlation radius of the incoherent fluctuations while its peak amplitude is of the same order of such fluctuations. Accordingly, the solitons can hardly be identified in the usual spatial or spectral domains, while their existence is clearly unveiled in the phase-space representation. Our multi-scale theory based on coupled coherent-incoherent wave turbulence formalisms reveals that the hidden solitons are stabilized and trapped by the incoherent localized structure. Furthermore, hidden binary soliton systems are identified numerically and described theoretically. The regime of hidden solitons is of potential interest for self-gravitating Boson models of "fuzzy" dark matter. It also sheds new light on the quantum-to-classical correspondence with gravitational interactions. The hidden solitons can be observed in nonlocal nonlinear optics experiments through the measurement of the spatial spectrogram.

description: A consistent theory of supersymmetry breaking must have a hidden sector, an observable sector, and must be embedded in a locally supersymmetric theory which arises from string theory. For phenomenological reasons it must also transmit supersymmetry from the hidden to the visible sector in a dominantly flavor neutral manner. Also any such theory of supersymmetry breaking has to take into account the problem of quadratic divergences which arise once the theory is embedded in supergravity. A class of possible models that arise from GKP-KKLT type IIB string compactifications, incorporating all this while being consistent with gauge unification, with just the bare minimum of necessary supergravity/string theory moduli fields coupled to the minimally supersymmetric standard model, is presented. Such models give reasonable values for the soft masses, the $μ$ and $Bμ$ terms and the gaugino masses. Assuming that an actual detailed realization exists, it is very likely that they are the simplest such possibility .

description: In autocracies, low-capacity protest campaigns that lack material and political resources are common, but these weaknesses make them vulnerable to reneging – the deliberate failure to implement concessions as promised. Reneging is critical to how and whether protests actually influence policy. Why are some autocratic concessions to low-capacity campaigns undermined by reneging? I argue concessions are most likely to be implemented when they matter least for meaningfully altering policy. Concessions that provide isolated conflict resolution without constraining state actors elsewhere are more likely to be implemented, while reneging affects concessions that would constrain state agents elsewhere. I find support for this argument using an original dataset of low-capacity protest campaigns in Moscow, Russia, from 2013 to 2018, which includes a novel approach to concessions data. Additionally, I show that reneging is less likely when the campaign demobilizes after the concession, though the effect on constraining concessions is limited. I also address why campaigns about some issues, like labour disputes, experience less reneging, and show that concessions from higher levels of government are just as prone to reneging as lower levels. This article advances scholarship on authoritarian responsiveness and non-violent political control by highlighting reneging as an overlooked response to protest.

description: AIMS: To demonstrate and test the capability of the next generation of low-frequency radio telescopes to perform high resolution observations across intra-continental baselines. Jupiter's strong burst emission is used to perform broadband full signal cross-correlations on time intervals of up to hundreds of milliseconds. METHODS: Broadband VLBI observations at about 20 MHz on a baseline of ~50000 wavelengths were performed to achieve arcsecond angular resolution. LOFAR's Initial Test Station (LOFAR/ITS, The Netherlands) and the Nancay Decametric Array (NDA, France) digitize the measured electric field with 12 bit and 14 bit in a 40 MHz baseband. The fine structure in Jupiter's signal was used for data synchronization prior to correlation on the time-series data. RESULTS: Strong emission from Jupiter was detected during snapshots of a few seconds and detailed features down to microsecond time-scales were identified in dynamic spectra. Correlations of Jupiter's burst emission returned strong fringes on 1 ms time-scales over channels as narrow as a hundred kilohertz bandwidth. CONCLUSIONS: Long baseline interferometry is confirmed at low frequencies, in spite of phase shifts introduced by variations in ionospheric propagation characteristics. Phase coherence was preserved over tens to hundreds of milliseconds with a baseline of ~700 km. No significant variation with time was found in the correlations and an estimate for the fringe visibility of 1, suggested that the source was not resolved. The upper limit on the source region size of Jupiter Io-B S-bursts corresponds to an angular resolution of ~3 arcsec. Adding remote stations to the LOFAR network at baselines up to thousand kilometers will provide 10 times higher resolution down to an arcsecond.

Integrating smart buildings and the smart grid using transactive energy as a core component provides building owners, system integrators, and suppliers with a great opportunity to provide enhanced services. As more building products become "grid aware" and "IoT aware" the opportunity to leverage their intelligence and capabilities is growing. More end devices can provide direct impact into the usage and coordination of distributed energy resources. Connecting these typically disparate systems into a common infrastructure using open interoperable concepts will provide greater costs savings, energy reliability and resilience, and easier management. This panel session will feature subject matter experts presenting these core concepts along with practical use cases and illustrative examples.

description: Legged robot navigation in extreme environments can hinder the use of cameras and laser scanners due to darkness, air obfuscation or sensor damage. In these conditions, proprioceptive sensing will continue to work reliably. In this paper, we propose a purely proprioceptive localization algorithm which fuses information from both geometry and terrain class, to localize a legged robot within a prior map. First, a terrain classifier computes the probability that a foot has stepped on a particular terrain class from sensed foot forces. Then, a Monte Carlo-based estimator fuses this terrain class probability with the geometric information of the foot contact points. Results are demonstrated showing this approach operating online and onboard a ANYmal B300 quadruped robot traversing a series of terrain courses with different geometries and terrain types over more than 1.2km. The method keeps the localization error below 20cm using only the information coming from the feet, IMU, and joints of the quadruped.

description: Action principles of the BF type for diffeomorphism invariant topological field theories living in n-dimensional spacetime manifolds are presented. Their construction is inspired by Cuesta and Montesinos' recent paper where Cartan's first and second structure equations together with first and second Bianchi identities are treated as the equations of motion for a field theory. In opposition to that paper, the current approach involves also auxiliary fields and holds for arbitrary n-dimensional spacetimes. Dirac's canonical analysis for the actions is detailedly carried out in the generic case and it is shown that these action principles define topological field theories, as mentioned. The current formalism is a generic framework to construct geometric theories with local degrees of freedom by introducing additional constraints on the various fields involved that destroy the topological character of the original theory. The latter idea is implemented in two-dimensional spacetimes where gravity coupled to matter fields is constructed out, which has indeed local excitations.

The smart grid initiative was conceived as a system that accommodates all supply options and enables customer participation, optimizes asset utilization and operation, and provides power quality and resilience. Significant utility projects in the last ten years have given the means to monitor the grid and to track usage at the customer meter level at much higher frequencies. Advanced analytics of the large volumes and velocity of the data from these monitoring and metering systems are allowing utilities to significantly improve their planning, operations, customer insights and risk management. This panel discusses the advances made in analytics technology and how they are being applied in the utility industry.

description: Technologies of speed, penetration and compression now enable images to be created, stored, mined, circulated and erased in new ways. Discoveries from astronomy to geology and computing expand human horizons while programmes of extractivism are prolonged in material, social and psychic worlds. The regime of data visualization that fuels contemporary science and markets alike naturalizes its authority over the representation of the present and the collective vision of species’ pasts and futures. Restrictions on our physical mobility and social habits in the current conditions of the pandemic confirm the vulnerability of our perceptual systems but also their capacity to transform.This paper envisages time beyond the exhausting and entropic image regimes that drive dominant forms of industrial and networked modernity. It does so through a series of studies of visual artworks featured in exhibitions that I have staged as artist-curator and initiator of The Habitat of Time (2018-). This international research project explores rapids shifts in our experience of time produced by the current conditions of unstable globalization. The durational, digital, sculptural and installation artworks explored in this paper have been presented at Arts Catalyst London (2020), Casula Powerhouse, Liverpool NSW (2018) and Artspace Sydney (2017). They demonstrate the ways in which artists conceive of new matterings of the image through their transdisciplinary research and speculative practice at the intersection of art, science and technology. In this expanded field, images show up as entanglements of material, social and perceptual forces, conveying the interdependency of human and more-than-human worlds.

description: Studies of noncooperative transitions find that domestic balances of power shaped postcommunist regime trajectories in favor of the powerful. Then, what determined the balance of power during a transition? Drawing on relational-network analysis in IR, I argue that the configuration of international ties determined the relative strength of democrats and Soviet-era elites. States with diversified ties between the US and the Soviet Union - that occupy a brokerage position- were more likely to democratize. Their ties with the US funneled material and non-material assistance into democrats in postcommunist states. However, states deeply integrated into the Soviet order resisted democratization to a greater extent. Their extensive ties to the Soviet order resulted in stronger Sovietization and Soviet legacies impeding democratization. The interplay of states' ties with the US and the Soviet Union, as a function of brokerage and integration, shaped the domestic balance of power, conditioning postcommunist political changes. Empirical analysis using medium-N analysis and case studies on the former Soviet Union republics lends support to the argument. The finding contributes to the literature on international determinants of regime changes by highlighting how underlying global power structures frame the domestic balance of power.
Observations of planetary nebulae with multi-element image sensors

description: Two silicon diode arrays have been used to obtain spectra of the planetary nebula NGC 7027. Relative line intensities (I(H)=100) are determined in the spectral region 5000-9900A. The resolution, good quantum efficiency, and the wide dynamic range available with these detectors permit: i) the resolution of close pairs for which only the blend intensity is presently available, e,.g. Paschen P8 9546 from the [SIII] 9532, and HeII 6683 from HeI 6678. ii) A much closer value of the theoretical ratio for the [SIII] 9069, 9532 lines to be obtained. iii) A better agreement with model predictions for the intensities of the [NII] doublet at 6548, 6584. This planetary was also observed with a 50x50 array through interference filters centered at [OIII] 5007, H 6563, and [SII] 6731. Regions of low and high excitation are determined by inspection of the ratios [SII]/H and [SII]/[OIII]. Variable extinction across the face of the nebula is shown to exist by constructing a two-dimensional map of the color excess E (H – [OIII]). A JPL CCD camera was used to obtain monocromatic images of the planetary nebulae NGC 2440, NGC 3132, and NGC 3242 through interference filters centered at Hβ 4861, H 6563, [NII] 6584, and [SIII] 9532. Two-dimensional data is presented in the form of false-color photographs obtained with a Comtal Imaging System. , This system has the capability of producing images with a brightness resolution of 8 bits per pixel in shades of gray, false or full color. Computer programmes have been written to handle the transfer of data frames from the main computer at UBC to the Comtal Imaging System. A two envelope structure, stratification of the radiation and local density fluctuations are obvious features of the images of NGC 2440, NGC 3132, and NGC 3242. All of them are consistent with an ejection of matter from a central star with non-zero angular momentum. Regions of low and high excitation are determined from the ratios [NII]/H, [SIII]/H, and [SIII]/[NII]. Color excess maps show that variable extinction is also present in these objects. Since the color excess increases outward for all of these objects, the indication is that the dust responsible for this extinction is concentrated more in the outer envelope than in the inner envelope.

description: AIMS: We want to understand the emission mechanism of radio emission from air showers to determine the origin of high-energy cosmic rays. Therefore, we study the geometry of the air shower radio emission measured with LOPES and search for systematic effects between the direction determined on the radio signal and the direction provided by the particle detector array KASCADE. METHODS: We produce 4D radio images on time-scales of nanoseconds using digital beam-forming. Each pixel of the image is calculated for three spatial dimensions and as a function of time. The third spatial dimension is obtained by calculating the beam focus for a range of curvature radii fitted to the signal wave front. We search this multi-dimensional parameter space for the direction of maximum coherence of the air shower radio signal and compare it to the direction provided by KASCADE. RESULTS: The maximum radio emission of air showers is obtained for curvature radii being larger than 3 km. We find that the direction of the emission maximum can change when optimizing the curvature radius. Furthermore, we find a tentative increase of the curvature radius to lower elevations, where the air showers pass through a larger atmospheric depth. CONCLUSIONS: We conclude that the angular resolution of LOPES is sufficient to determine the direction which maximizes the observed electric field amplitude. However, the statistical uncertainty of the directions is not determined by the resolution of LOPES, but by the uncertainty of the curvature radius. We do not find any systematic deviation between the directions determined from the radio signal and from the detected particles. This result places a strong supportive argument for the use of the radio technique to study the origin of high-energy cosmic rays.
