description: A beam line for electrons with energies in the range of 1 to 45 GeV, low contamination of hadrons and muons and high intensity up to 10^6 per accelerator spill at 27 GeV was setup at U70 accelerator in Protvino, Russia. A beam tagging system based on drift chambers with 160 micron resolution was able to measure relative electron beam momentum precisely. The resolution sigma_p p was 0.13% at 45 GeV where multiple scattering is negligible. This test beam setup provided the possibility to study properties of lead tungstate crystals (PbWO_4) for the BTeV experiment at Fermilab.

description: We study half-BPS 't Hooft line operators in 4d $\mathcal{N}=2$ $U(N)$ gauge theories on $S^1\times \mathbb{R}^3$ with an $Ω$-deformation. The recently proposed brane construction of 't Hooft operators shows that non-perturbative contributions to their correlator are identified with the Witten indices of quiver supersymmetric quantum mechanics. For the products of minimal 't Hooft operators, a chamber in the space of Fayet-Iliopoulos parameters in the quantum mechanics corresponds to an ordering of the operators inserted along a line. These considerations lead us to conjecture that the Witten indices can be read off from the Moyal products of the expectation values of the minimal 't Hooft operators, and also that wall-crossing occurs in the quantum mechanics only when the ordering of the operators changes. We confirm the conjectures by explicitly computing the Witten indices for the products of two and three minimal 't Hooft operators in all possible chambers.

description: Cholesteryl ester transfer protein (CETP) belongs to the group of enzymes which inhibition have the application in the treatment of cardiovascular diseases. This study presents QSAR modeling for a set of compounds acting as CETP inhibitors based on the Monte Carlo optimization with SMILES notation and molecular graph-based descriptors, and field-based 3D modeling. A 3D QSAR model was developed for one random split into the training and test sets, whereas conformation independent QSAR models were developed for three random splits, with the results suggesting there is an excellent correlation between them. Various statistical approaches were used to assess the statistical quality of the developed models, including robustness and predictability, and the obtained results were very good. This study used a novel statistical metric known as the index of ideality of correlation for the final assessment of the model, and the results that were obtained suggested that the model was good. Also, molecular fragments which account for the increases and/or decreases of a studied activity were defined and then used for the computer-aided design of new compounds as potential CETP inhibitors. The final assessment of the developed QSAR model and designed inhibitors was done using molecular docking, which revealed an excellent correlation with the results from QSAR modeling.

description: The mechanism for transitions from phase to defect chaos in the one-dimensional complex Ginzburg-Landau equation (CGLE) is presented. We introduce and describe periodic coherent structures of the CGLE, called Modulated Amplitude Waves (MAWs). MAWs of various period P occur naturally in phase chaotic states. A bifurcation study of the MAWs reveals that for sufficiently large period P, pairs of MAWs cease to exist via a saddle-node bifurcation. For periods beyond this bifurcation, incoherent near-MAW structures occur which evolve toward defects. This leads to our main result: the transition from phase to defect chaos takes place when the periods of MAWs in phase chaos are driven beyond their saddle-node bifurcation.

description: This work explores fundamental statistical and thermodynamic properties of short-and long-range-interacting systems. The purpose of this study is twofold. Firstly, we rigorously prove that the probability distribution of arbitrary few-body observables is restricted by a Gaussian concentration bound (or Chernoff--Hoeffding inequality) above some threshold temperature. This bound is then derived for arbitrary Gibbs states of systems that include long-range interactions Secondly, we establish a quantitative relationship between the concentration bound of the Gibbs state and the equivalence of canonical and micro-canonical ensembles. We then evaluate the difference in the averages of thermodynamic properties between the canonical and the micro-canonical ensembles. Under the assumption of the Gaussian concentration bound on the canonical ensemble, the difference between the ensemble descriptions is upper-bounded by $\left[n^{-1} \log (n^{3/2}Δ^{-1})\right]^{1/2}$ with $n$ being the system size and $Δ$ being the width of the energy shell of the micro-canonical ensemble This limit gives a non-trivial upper bound \textit{exponentially small energy width} with respect to the system size. By combining these two results, we prove the ensemble equivalence as well as the weak eigenstate thermalization in arbitrary long-range-interacting systems above a threshold temperature.

description: Inequality emerged as a social concern during the Enlightenment and was seen as violating the norm of human equality. Three main development narratives were generated following this concern: one of long-term equalization (de Tocqueville), one of polarization (Marx), and one of modern rising inequality followed by equalization (Kuznets). Although each of these narratives was able to score some points, none of them fully captured the actual trajectory of the inequality curve which is currently bending upwards towards more inequality. 21st century inequality studies are taking off in new directions, multiscalar, multi-dimensionally rooted in recent moral philosophy, and more focused on causal mechanisms and forces. Since early modernity a centre of economic inequality in the world, Latin America has a special relevance to inequality studies. Nevertheless, it is currently the only world region with a predominant tendency of equalization.
title: Parasitic Feed Elements for Reflector Antennas
Creators: name: Durnan, Gregory J.
Publisher: name: Griffith University
Year: 2005
Subjects: subject: Parasitic wire dipoles
subject: parabolic reflector antenna
subject: reflection coefficient

description: The use of parasitic wire dipoles are examined when placed in the proximity of a focused dipole feed in a parabolic reflector antenna. These parasitic elements are rotated around the feed dipole and a search is performed for the ideal positioning so as to yield maximum radiated power and main beam shift in order to develop a novel form of angle diversity. In addition a comparison is made between 2 element dipole feed structures and linearly and circularly polarised patch feed structures. In order to analytically model the structure, mutual coupling between feed elements is calculated taking into account a varying reflection coe±cient due to an impedance mismatch between the transmission line and driven element. An analytical treatment of the calculation of the radiated co-polar and cross-polar feed pattern is presented in addition to the projected field at the reflector surface. A comparison is made to the results presented by E.M.T Jones in the 1954 IRE Transactions of Antennas and Propagation paper entitled 'Paraboloid Reflector and Hyperboloid Lens Antennas'. A theoretical treatment of the reflected field and far field radiation pattern is then presented using the methods of Geometrical Optics, Physical Optics and Fourier analysis. The author derives analytical equations for multiple element incident feed fields and surface current equations for half wave feeds of arbitrary position and number. The fndings are confirmed using a comparison of three methods. These are; original code developed from analytical derivations, the NEC2 Method of Moments using a meshed reflector model and finally, by experimental methods. Analysis of a 30cm 0.4 F/D prime focus reflector at 3GHz using a 2 element feed yields up to 2dB gain over a single dipole feed when the element is displaced either laterally or at 60 or 120 degrees from the feed axis. The optimum offset from the driven element is in the 0.4 to 0.6¸ range. Maximum beam shift for this structure at the half power points is shown to be approximately 10 degrees. When designed as a low-cost system with undemanding polarisation requirements the structure presented provides an easily implemented or retrofitted alternative to multiple antenna diversity solutions.

description: Learning portable neural networks is very essential for computer vision for the purpose that pre-trained heavy deep models can be well applied on edge devices such as mobile phones and micro sensors. Most existing deep neural network compression and speed-up methods are very effective for training compact deep models, when we can directly access the training dataset. However, training data for the given deep network are often unavailable due to some practice problems (e.g. privacy, legal issue, and transmission), and the architecture of the given network are also unknown except some interfaces. To this end, we propose a novel framework for training efficient deep neural networks by exploiting generative adversarial networks (GANs). To be specific, the pre-trained teacher networks are regarded as a fixed discriminator and the generator is utilized for derivating training samples which can obtain the maximum response on the discriminator. Then, an efficient network with smaller model size and computational complexity is trained using the generated data and the teacher network, simultaneously. Efficient student networks learned using the proposed Data-Free Learning (DAFL) method achieve 92.22% and 74.47% accuracies using ResNet-18 without any training data on the CIFAR-10 and CIFAR-100 datasets, respectively. Meanwhile, our student network obtains an 80.56% accuracy on the CelebA benchmark.

description: This article discusses the filmic representation of the infamous Wannsee Conference, when fifteen senior German officials met at a villa on the shore of a Berlin lake to discuss and co-ordinate the implementation of the so-called final solution to the Jewish question. The understanding reached during the course of the ninety-minute meeting cleared the way for the Europe-wide killing of six million Jews. The article sets out to answer the principal challenge facing anyone attempting to recreate the Wannsee Conference on film: what was the atmosphere of this conference and the attitude of the participants? Moreover, it discusses various ethical aspects related to the portrayal of evil, not in actions but in words, using the medium of film. In doing so, it focuses on the BBC/HBO television film Conspiracy (2001), directed by Frank Pierson, probing its historical accuracy and discussing its artistic credibility.

description: The hot beaming (or strahl) electrons responsible for the main electron heat-flux in the solar wind are believed to be self-regulated by the electromagnetic beaming instabilities, also known as the heat-flux instabilities. Here we report the first quasi-linear theoretical approach of the whistler unstable branch able to characterize the long-term saturation of the instability as well as the relaxation of the electron velocity distributions. The instability saturation is not solely determined by the drift velocities, which undergo only a minor relaxation, but mainly from a concurrent interaction of electrons with whistlers that induces (opposite) temperature anisotropies of the core and beam populations and reduces the effective anisotropy. These results might be able to (i) explain the low intensity of the whistler heat-flux fluctuations in the solar wind (although other explanations remain possible and need further investigation), and (ii) confirm a reduced effectiveness of these fluctuations in the relaxation and isotropization of the electron strahl and in the regulation of the electron heat-flux.

description: In this paper the well known Belinskii and Zakharov soliton generating transformations of the solution space of vacuum Einstein equations with two-dimensional Abelian groups of isometries are considered in the context of the so called "monodromy transform approach", which provides some general base for the study of various integrable space - time symmetry reductions of Einstein equations. Similarly to the scattering data used in the known spectral transform, in this approach the monodromy data for solution of associated linear system characterize completely any solution of the reduced Einstein equations, and many physical and geometrical properties of the solutions can be expressed directly in terms of the analytical structure on the spectral plane of the corresponding monodromy data functions. The Belinskii and Zakharov vacuum soliton generating transformations can be expressed in explicit form (without specification of the background solution) as simple (linear-fractional) transformations of the corresponding monodromy data functions with coefficients, polynomial in spectral parameter. This allows to determine many physical parameters of the generating soliton solutions without (or before) calculation of all components of the solutions. The similar characterization for electrovacuum soliton generating transformations is also presented.

description: The increased rate of change in organizations, and a failure rate up to 70% (Kotter, 1990; Higgs & Rowland, 2000; Pasmore, 2011), has led to an increase in research concerning organizational change. However, the literature still has yet to identify the ideal set of change implementation strategies.  While leadership is argued to be an essential element to successful change the research on the specific behaviors and skills needed of change leaders is still in development (Beer & Walton, 1987). More investigation needs to be done concerning the identification and measurement of behaviors and skills related to successful organizational change. The current study contributes to this area in the literature. The aim was to develop and validate an instrument, the Change Leader Behavioral Inventory. The instrument identifies distinct behavioral dimensions associated with organizational change and the relationships among them. The goal was to provide a tool for individuals who lead change to receive feedback from their direct reports on how well they perform change related behaviors during a change initiative. The feedback will be beneficial to guide the professional development of change leaders.
      	In order to develop the Change Leader Behavioral Inventory many areas of the change literature were considered. The psychometric validation of the Change Leader Behavioral Inventory was based on a modified version of Hinkin’s (1998) framework for instrument validation. The instrument was administered in an online survey to employed individuals who had been through organizational change. The analysis of the survey responses (N = 405) provided support for the hypothesized model which consisted of seven categories of change. There was also support for the addition of another dimension to the instrument, resulting in an eight-factor model which will be used for future research. The results and implications for future research and practice will be discussed.

description: Clustered count data are commonly analysed by the generalized linear mixed model (GLMM). Here, the correlation due to clustering and some overdispersion is captured by the inclusion of cluster-specific normally distributed random effects. Often, the model does not capture the variability completely. Therefore, the GLMM can be extended by including a set of gamma random effects. Routinely, the GLMM is fitted by maximizing the marginal likelihood. However, this process is computationally intensive. Although feasible with medium to large data, it can be too time-consuming or computationally intractable with very large data. Therefore, a fast two-stage estimator for correlated, overdispersed count data is proposed. It is rooted in the split-sample methodology. Based on a simulation study, it shows good statistical properties. Furthermore, it is computationally much faster than the full maximum likelihood estimator. The approach is illustrated using a large dataset belonging to a network of Belgian general practices.

description: We present an analysis of seven strongly gravitationally lensed quasars and the corresponding constraints on the properties of dark matter. Our results are derived by modelling the lensed image positions and flux-ratios using a combination of smooth macro models and a population of low-mass haloes within the mass range 10^6 to 10^9 Msun. Our lens models explicitly include higher-order complexity in the form of stellar discs and luminous satellites, as well as low-mass haloes located along the observed lines of sight for the first time. Assuming a Cold Dark Matter (CDM) cosmology, we infer an average total mass fraction in substructure of f_sub = 0.012^{+0.007}_{-0.004} (68 per cent confidence limits), which is in agreement with the predictions from CDM hydrodynamical simulations to within 1 sigma. This result is closer to the predictions than those from previous studies that did not include line-of-sight haloes. Under the assumption of a thermal relic dark matter model, we derive a lower limit on the particle relic mass of m th > 5.58 keV (95 per cent confidence limits), which is consistent with a value of m_th > 5.3 keV from the recent analysis of the Ly-alpha forest. We also identify two main sources of possible systematic errors and conclude that deeper investigations in the complex structure of lens galaxies as well as the size of the background sources should be a priority for this field.

description: The phrase "Internet of Things Security" refers to a broad category of tactics, equipment, procedures, frameworks, and techniques utilized to safeguard every facet of the internet of things. The safeguarding of the hardware, software, data, and network connections to guarantee the availability, confidentiality, and integrity of IoT ecosystems is all part of IoT security. There are several security issues due to the large number of vulnerabilities that are frequently found in IoT systems. All aspects of protection, including as component hardening, monitoring, firmware updates, access control, threat response, and vulnerability remediation, are included in robust IoT security. IoT security is essential since these systems are widely dispersed and susceptible to attack, making them a highly focused attack vector. By preventing unwanted access, IoT devices can be protected from becoming entry points into the network and from leaking private data. Vulnerabilities in IoT security can be identified in watches, smart home appliances, cars, and smart grids.

description: Repertoire-based learning is a data-efficient adaptation approach based on a two-step process in which (1) a large and diverse set of policies is learned in simulation, and (2) a planning or learning algorithm chooses the most appropriate policies according to the current situation (e.g., a damaged robot, a new object, etc.). In this paper, we relax the assumption of previous works that a single repertoire is enough for adaptation. Instead, we generate repertoires for many different situations (e.g., with a missing leg, on different floors, etc.) and let our algorithm selects the most useful prior. Our main contribution is an algorithm, APROL (Adaptive Prior selection for Repertoire-based Online Learning) to plan the next action by incorporating these priors when the robot has no information about the current situation. We evaluate APROL on two simulated tasks: (1) pushing unknown objects of various shapes and sizes with a robotic arm and (2) a goal reaching task with a damaged hexapod robot. We compare with "Reset-free Trial and Error" (RTE) and various single repertoire-based baselines. The results show that APROL solves both the tasks in less interaction time than the baselines. Additionally, we demonstrate APROL on a real, damaged hexapod that quickly learns to pick compensatory policies to reach a goal by avoiding obstacles in the path.

description: We study the phenomenon of neutrino spin-flavor oscillations due to solar magnetic fields. This allows us to examine how significantly the electron neutrinos produced in the solar interior undergo a resonant spin-flavor conversion. We construct analytical models for the solar magnetic field in all the three regions of the Sun. Neutrino spin-flavor oscillations in these magnetic fields are examined by studying the level crossing phenomenon and comparing the two cases of zero and non-zero vacuum mixing respectively. Results from the Borexino experiment are used to place an upper limit on the magnetic field in the solar core. Related phenomena such as effects of matter on neutrino spin transitions and differences between Dirac and Majorana transitions in the solar magnetic fields are also discussed.

description: This thesis is about access to higher and further education for children and young people in out-of-home care. There are almost 40,000 children and young people living in out-of-home care in Australia. They are consistently identified as one of the most vulnerable population groups in society. The low educational attainment of children and young people in out-of-home care compared to their peers has been noted, including low levels of participation in higher and further education. In Australia, there is a lack of data about higher and further education attainment of young people in out-of-home care with no current mechanisms to identify care leaver outcomes after exiting the care system. The few Australian studies which have been conducted show higher and further education attainment mirrors international trends, which show the low education attainment for this group. Post-secondary education, such as TAFE and university, is an important gateway to health and emotional wellbeing, job satisfaction and financial security in adult life. This is one factor that contributes to children and young people who have been in out-of home care persisting as a highly vulnerable population group in society.

Spin Dynamics of CPMG sequence in time-dependent magnetic fields

description: We analyze the effects of time dependent magnetic and RF fields on the spin dynamics of the Carr-Purcell-Meiboom-Gill (CPMG) sequence. The analysis is based on the decomposition of the magnetization into the eigenmodes of the propagator of a single refocusing cycle. For sufficiently slow changes in the external fields, the magnetization follows the changing eigenmodes adiabatically. This results in echo amplitudes that show regular modulations with time. Faster field changes can induce transitions between the eigenmodes. Such non-adiabatic behavior occurs preferentially at particular offsets of the Larmor frequency from the RF frequency where the eigenmodes become nearly degenerate. We introduce the instantaneous adiabaticity parameter ${\cal A}(t)$ that accurately predicts the crossover from the adiabatic to the non-adiabatic regime and allows the classification of field fluctuations. ${\cal A}(t)$ is determined solely by the properties of a single refocusing cycle under static conditions and the instantaneous value of the field offset and its temporal derivative. The analytical results are compared with numerical simulations.

description: The European Union’s (EU) Common Foreign and Security Policy (CFSP) and its accompanying Common Security and Defense Policy (CSDP) missions are tools used to increase the international profile of the EU. Using three different databases, this study features a content analysis that evaluates how much and what kind of media coverage CSDP missions receive. In general, the news coverage is positive, but limited. This article argues that the problem is structural: the very nature of the missions themselves, whether EU or NATO, makes them poor vehicles for EU promotion for political, institutional, and logistical reasons. By definition, they are conducted in the middle of crises, making news coverage politically sensitive. The very act of reporting could undermine the mission. Institutionally, all CSDP missions are intergovernmental; therefore, the member states control the coverage. Logistically, the missions are usually located in remote, undeveloped parts of the world, making it difficult and expensive for European and international journalists to cover. Moreover, these regions in crisis seldom have a thriving, local free press. The author concludes that although a mission may do good, CSDP missions cannot fulfill their primary political function of raising the profile of the EU.

description: In order to quantitatively account of tegafur drug interaction with graphene oxide nanosheet, various geometrical structures are examined to study the detailed effects of drug adsorption on the structural properties, interaction energy and charge transfer of the studied complexes at the microscopic level using the density functional theory study. The bond paths at the quantum theory of atoms in molecules’ bond critical points show that the considered complexes are stabilized by the O…H hydrogen bond intermolecular interactions. In addition, the molecular dynamics simulations are applied to simulate drug release in response to the temperature change in the physiological pH. The increasing the temperature of the simulation system from 310 to 315 K has the effect of decreasing the strength of intermolecular attraction and subsequently, liberation of the adsorbed drugs from the surface of the nanosheet is observed.

description: Governance in Räumen begrenzter Staatlichkeit ist ein vergleichsweise junges Forschungsfeld. Seine gemeinschaftliche Bearbeitung im interdisziplinären Sonderforschungsbereich (SFB) 700 setzt einerseits eine Bestimmung der Grenzen des Feldes und andererseits eine gemeinsame Sprache voraus. Eine Einigung auf Kernkonzepte und Grundbegriffe ist in diesem Sinne zentrale Bedingung einer erfolgreichen gemeinsamen Erforschung von Governance in Räumen begrenzter Staatlichkeit. Aus diesem Grund haben die Wissenschaftlerinnen und Wissenschaftler des SFB 700 im ersten Forschungsjahr 2006/2007 eine rege Debatte um eine gemeinsame begriffliche und konzeptuelle Forschungsgrundlage geführt. Das vorliegende Arbeitspapier fasst die bisherigen Ergebnisse dieser Debatte zusammen. Es versteht sich in erster Linie als interne Serviceleistung an den Gesamt-SFB und hat den Charakter eines Zwischenberichts. Denn letztlich entscheidet die fortschreitende Erkenntnis im SFB 700 über Erweiterungen des Kanons an zentralen Begriffen und Konzepten oder über notwendige Revisionen. Auf die Irritationen aus der empirischen Forschung ist der SFB 700 in diesem Sinne gespannt und begreift die folgenden Begriffsklärungen als work in progress. Entwürfe zu dem vorliegenden Glossar wurden von verschiedenen Mitgliedern des SFB 700 geliefert, denen wir an dieser Stelle herzlich danken wollen. Die Kernbegriffe des Glossars selbst wurden dann auf einer Klausurtagung des SFB 700 im Januar 2007 sowie auf späteren Jours Fixes während des Sommersemesters diskutiert. Außerdem fließen hier die Ergebnisse der Eröffnungskonferenz des SFB 700 ein, die im Februar 2007 stattfand. Allen Teilnehmerinnen und Teilnehmern an den vielfältigen Diskussionen sei herzlich gedankt. Der hier vorliegende Text wird vom Teilprojekt A1 des SFB 700 verantwortet und versteht sich – wie gesagt – als Serviceleistung an den Sonderforschungsbereich und darüber hinaus.

description: A complete characterization is obtained of the asymptotic behavior of solutions of the static vacuum Einstein equations which have a (pseudo)-compact horizon or boundary and are complete away from the boundary. It is proved that the time-symmetric space-like hypersurface has only finitely many ends, each of which is either asymptotically flat (AF) or parabolic, as in the (static) Kasner metric. Examples are given with both types of behavior, together with an extensive discussion and new characterization of Weyl metrics. The asymptotics result allows one in most circumstances to drop the AF assumption from the static black hole uniqueness theorems and replace it with just a completeness assumption.
