Subjects: Education--Adult and Continuing

description: Intimate partner violence is a serious concern with consequences related to physical, social, and emotional health of individuals, families, and society. Despite extensive research and targeted strategies to address this problem, incidents of intimate partner violence occur while local, provincial, and national agencies track this violence over time. Emerging adults are in a life stage where they are forming beliefs about intimate partner relationships. They are engaged in adult learning that occurs incidentally as they navigate experiences in life, work, and love. As such, they are in a position to contribute to an understanding of the range of intimate partner relationships (healthy, unhealthy, and violent) with the possibility of informing strategies aimed at preventing this violence. In light of the magnitude of the concern of intimate partner violence, I conducted a study using hermeneutics as a philosophy and method to explore how emerging adults understand violence in relationships. Data sources included unstructured interviews with 12 individuals aged 18 to 29 years and media reports of a critical incident of intimate partner violence wherein four young people were shot by an ex-boyfriend of one of the young adults before he shot himself. Findings included: the importance of being connected to friends and not isolating oneself; the existence of sexual pressure and issues of ambiguity regarding consent to sexual activity; the challenge of recognizing violence in relationships and the stigma that goes with labelling it as such; the influence of media reports of intimate partner violence, in particular the use of the rhetoric of he seemed like such a nice guy; the powerful impact that texting has in communication between emerging adults in intimate partner relationships and its connection to stalking and jealousy; and the protective effect of loving family and friends on young people as they navigate intimate partner relationships. Implications of this study include the possibility of multiple strategies for prevention of intimate partner violence situated in adult learning. These strategies include utilizing the voices of emerging adults to reflect the challenge of recognizing and naming violence in relationships to make a powerful impact on cognitive and emotional levels.

description: We consider the discrete time unitary dynamics given by a quantum walk on $\Z^d$ performed by a particle with internal degree of freedom, called coin state, according to the following iterated rule: a unitary update of the coin state takes place, followed by a shift on the lattice, conditioned on the coin state of the particle. We study the large time behavior of the quantum mechanical probability distribution of the position observable in $\Z^d$ for random updates of the coin states of the following form. The random sequences of unitary updates are given by a site dependent function of a Markov chain in time, with the following properties: on each site, they share the same stationnary Markovian distribution and, for each fixed time, they form a deterministic periodic pattern on the lattice. We prove a Feynman-Kac formula to express the characteristic function of the averaged distribution over the randomness at time $n$ in terms of the nth power of an operator $M$. By analyzing the spectrum of $M$, we show that this distribution posesses a drift proportional to the time and its centered counterpart displays a diffusive behavior with a diffusion matrix we compute. Moderate and large deviations principles are also proven to hold for the averaged distribution and the limit of the suitably rescaled corresponding characteristic function is shown to satisfy a diffusion equation. An example of random updates for which the analysis of the distribution can be performed without averaging is worked out. The random distribution displays a deterministic drift proportional to time and its centered counterpart gives rise to a random diffusion matrix whose law we compute. We complete the picture by presenting an uncorrelated example.

description: In the past few decades detailed observations of radio and X-rays emission from massive binary systems revealed a whole new physics present in such systems. Both thermal and non-thermal components of this emission indicate that most of the radiation at these bands originates in shocks. OB and WR stars present supersonic and massive winds that, when colliding, emit largely due to the free-free radiation. The non-thermal radio and X-ray emissions are due to synchrotron and inverse compton processes, respectively. In this case, magnetic fields are expected to play an important role on the emission distribution. In the past few years the modeling of the free-free and synchrotron emissions from massive binary systems have been based on purely hydrodynamical simulations, and ad hoc assumptions regarding the distribution of magnetic energy and the field geometry. In this work we provide the first full MHD numerical simulations of wind-wind collision in massive binary systems. We study the free-free emission characterizing its dependence on the stellar and orbital parameters. We also study self-consistently the evolution of the magnetic field at the shock region, obtaining also the synchrotron energy distribution integrated along different lines of sight. We show that the magnetic field in the shocks is larger than that obtained when the proportionality between $B$ and the plasma density is assumed. Also, we show that the role of the synchrotron emission relative to the total radio emission has been underestimated.

description: The BaCe0.8Y0.2O3-δ proton conductor under hydration and under compressive strain has been analyzed with high pressure Raman spectroscopy and high pressure x-ray diffraction. The pressure dependent variation of the Ag and B2g bending modes from the O-Ce-O unit is suppressed when the proton conductor is hydrated, affecting directly the proton transfer by locally changing the electron density of the oxygen ions. Compressive strain causes a hardening of the Ce-O stretching bond. The activation barrier for proton conductivity is raised, in line with recent findings using high pressure and high temperature impedance spectroscopy. The increasing Raman frequency of the B1g and B3g modes thus implies that the phonons become hardened and increase the vibration energy in the a-c crystal plane upon compressive strain, whereas phonons are relaxed in the b-axis, and thus reveal softening of the Ag and B2g modes. Lattice toughening in the a-c crystal plane raises therefore a higher activation barrier for proton transfer and thus anisotropic conductivity. The experimental findings of the interaction of protons with the ceramic host lattice under external strain may provide a general guideline for yet to develop epitaxial strained proton conducting thin film systems with high proton mobility and low activation energy.

description: We studied the feasibility of the measurement of Higgs pair creation at a Photon Linear Collider (PLC). From the sensitivity to the anomalous self-coupling of the Higgs boson, the optimum $γγ$ collision energy was found to be around 270 GeV for a Higgs mass of 120 GeV/$c^2$. We found that large backgrounds such as $γγ\rightarrow W^+W^-, ZZ,$ and $b\bar{b}b\bar{b}$, can be suppressed if correct assignment of tracks to parent partons is achieved and Higgs pair events can be observed with a statistical significance of $\sim 5 σ$ by operating the PLC for 5 years.

description: Training working memory (WM) to increase WM capacity and fluid intelligence (Gf) has received much experimental attention in recent years, though its efficacy remains highly controversial. The current study investigated the effect of a randomized six-week online WM intervention on cognitive abilities and patterns of neural activation in a community-recruited sample of healthy young adults, in relation to both a processing speed training active control condition, as well as a no-contact control condition. Results of this randomized trial are discussed in three parts: Chapter 2 examines group-level fMRI activation patterns for tasks of WM and Gf before the training intervention. Consistent with previous research, results indicate large areas of fronto-parietal activation in response to increasing task demands for our WM task, which largely subsume more circumscribed regions of activation for our Gf task. These results are discussed in terms of a task-general central network which may underlie performance of WM, Gf, and perhaps even goal-directed behaviour more generally. Chapter 3 investigates potential differences in a wide range of cognitive test scores before and after WM training, processing speed training, or no-contact. Results revealed support for the null hypothesis across all cognitive tests administered. Because these results are consistent with experimental trials of equal or greater methodological rigor, we suggest that future research re-focus on promising interventions known to increase memory performance in healthy young adults; and/or examine alternative populations in which WM training may be efficacious. Chapter 4 examines potential differences in pre- and post-training patterns of neural activation for WM and Gf tasks in our WM training, and processing speed training groups. Results indicated significant post-training reductions in activation for the WM trained group in relation to the processing speed group for the WM task, but not the Gf task. These results suggest that WM training does not affect patterns of neural activation for Gf tasks. We suggest that future research investigate neural correlates of WM training in populations for which WM itself is impaired; and/or WM training interventions in populations that have returned more promising results compared to those with healthy young adults.

description: We demonstrate spin-accumulation signals controlled by the gate voltage in a metal-oxide-semiconductor field effect transistor structure with a Si channel and a CoFe/$n^{+}$-Si contact at room temperature. Under the application of a back-gate voltage, we clearly observe the three-terminal Hanle-effect signal, i.e., spin-accumulation signal. The magnitude of the spin-accumulation signals can be reduced with increasing the gate voltage. We consider that the gate controlled spin signals are attributed to the change in the carrier density in the Si channel beneath the CoFe/$n^{+}$-Si contact. This study is not only a technological jump for Si-based spintronic applications with gate structures but also reliable evidence for the spin injection into the semiconducting Si channel at room temperature.

description: This thesis presents the first results of broadband polarimetry of the HI, OH, Recombination Line Survey of the Milky Way (THOR) pilot region. The THOR pilot survey covers l = 29.2 degrees to 31.5 degrees, |b| < 1 degree at frequencies from 988.433 MHz to 2012.433 MHz with an angular resolution that ranges from 24.4'' x 15.1'' at 988.433 MHz to 9.0'' x 8.3'' at 2012.433 MHz. After calibrating the visibility data for total intensity as well as polarization two mini-mosaics image cubes were made for the targets of this thesis. The two targets studied within the THOR pilot region presented in this thesis are the supernova remnant (SNR) Kes 75 and the star formation region W43-Main. At the frequencies of the THOR survey are thermal and synchrotron emission. By the use of Rotation Measure (RM) synthesis, it is found that the pulsar wind nebula (PWN) in Kes 75 and some diffuse emission in W43-Main display complex Faraday rotation.

description: We present multiwavelength optical linear polarimetric observations of 69 stars toward the young open cluster Be 59. The observations reveal the presence of three dust layers located at the distances of \sim300, \sim500 and \sim700 pc. The dust layers produce a total polarization Pv \sim 5.5 per cent. The mean values of polarization and polarization angles due to the dust layers are found to increase systematically with distance. We show that polarimetry in combination with the (U - B) - (B - V) colour-colour diagram yields a better identification of cluster members. The polarization measurements suggest that the polarization due the intra-cluster medium is \sim 2.2 per cent. An anomalous reddening law exists for the cluster region, indicating a relatively larger grain size than that in the diffuse ISM. The spatial variation of the polarization and E(B - V) is found to increase with radial distance from the cluster center, whereas the θv and λmax are found to decrease with increasing radial distance from the cluster center. About 40 per cent of cluster members show the signatures of either intrinsic polarization or rotation in their polarization angles. There is an indication that the star light of the cluster members might have been depolarized because of non-uniform alignment of dust grains in the foreground dust layers and in the intra-cluster medium.

Physical and genetic interactions involving the nonhomologous end-joining factor XLF/Nej1

description: DNA double-strand breaks (DSBs) are potentially toxic lesions. Maintenance of genomic stability requires the proper repair of DSBs by either the nonhomologous end-joining (NHEJ) pathway or the homologous recombination (HR) pathway. The XRCC4-like factor (XLF) and the NHEJ defective protein 1 (Nej1), stimulate the repair of DSBs by NHEJ in humans and Saccharomyces cerevisiae, respectively. The precise mechanism(s) through which XLF/Nej1 functions remain poorly understood. I show that the C-terminal region (CTR) of XLF is required for DNA binding and contains a conserved phenylalanine that is important for its interaction with Ku70/80 and for recruitment of XLF to DSBs in vivo. Surprisingly, I find that loss of the XLF-Ku interaction does not affect repair as measured by γ-H2AX foci resolution in vivo. In contrast, I show that while the CTR of the XLF homolog in S. cerevisiae, Nej1, is not required for recruitment to DSBs in vivo, it is critical for NHEJ in vivo. Previous studies by other groups have demonstrated a crucial role for the interaction between XLF and X-ray repair cross-complementing protein 4 (XRCC4) for NHEJ in vitro and in vivo. Similarly, I find that the interaction between Nej1 and the S. cerevisiae homolog of XRCC4, ligase interacting factor 1 (Lif1), correlates with NHEJ activity in vivo. These results bolster the current model of XLF function in which XLF/Nej1 stimulates NHEJ through its interaction with XRCC4/Lif1. In addition, my results uncover important differences in how XLF and Nej1 provide this function and provide useful tools for future investigation of the precise structural mechanism underlying their stimulation of NHEJ. I have also uncovered novel genetic interactions between an uncharacterized yeast gene, maintenance of telomere capping 5 (MTC5), the HR factor RAD52, and NHEJ factors including NEJ1. I show that MTC5 does not regulate NHEJ, but does regulate telomere length and dNTP levels. Based on a recent report and previously reported genetic interactions involving MTC5, I propose that the telomere length defects observed in mtc5Δ cells and the genetic interactions between MTC5, RAD52, and NHEJ factors may result from decreased dNTP levels and defects in amino acid uptake.

description: We present 12CO, 13CO and C18O J=3-2 maps of the W3 GMC made at the James Clerk Maxwell Telescope. We combine these observations with Five Colleges Radio Astronomy Observatory CO J=1-0 data to produce the first map of molecular-gas temperatures across a GMC and the most accurate determination of the mass distribution in W3 yet obtained. We measure excitation temperatures in the part of the cloud dominated by triggered star formation (the High Density Layer, HDL) of 15-30 K, while in the rest of the cloud, which is relatively unaffected by triggering (Low Density Layer, LDL), the excitation temperature is generally less than 12 K. We identify a temperature gradient in the HDL which we associate with an age sequence in the embedded massive star-forming regions. We measure the mass of the cloud to be 4.4+/-0.4 x 10^5 solar masses, in agreement with previous estimates. Existing sub-mm continuum data are used to derive the fraction of gas mass in dense clumps as a function of position in the cloud. This fraction, which we interpret as a Clump Formation Efficiency (CFE), is significantly enhanced across the HDL, probably due to the triggering. Finally, we measure the 3D rms Mach Number as a function of position and find a correlation between the Mach number and the CFE within the HDL only. This correlation is interpreted as due to feedback from the newly-formed stars and a change in its slope between the three main star-forming regions is construed as another evolutionary effect. We conclude that triggering has affected the star-formation process in the W3 GMC primarily by creating additional dense structures that can collapse into stars. Any traces of changes in CFE due to additional turbulence have since been overruled by the feedback effects of the star-forming process itself.

Parameter learning for a readability checking tool

Publisher: name: Zenodo
Year: 2019

description: This paper describes the application of machine learning methods to determine parameters for DeLite, a readability checking tool. DeLite pinpoints text segments that are difficult to understand and computes for a given text a global readability score, which is a weighted sum of normalized indicator values. Indicator values are numeric properties derived from linguistic units in the text, such as the distance between a verb and its complements or the number of possible antecedents for a pronoun. Indicators are normalized by means of a derivation of the Fermi function with two parameters. DeLite requires individual parameters for this normalization function and a weight for each indicator to compute the global readability score.

Several experiments to determine these parameters were conducted, using different machine learning approaches. The training data consists of more than 300 user ratings of texts from the municipality domain. The weights for the indicators are learned using two approaches: i) robust regression with linear optimization and ii) an approximative iterative linear regression algorithm. For evaluation, the computed readability scores are compared to user ratings. The evaluation showed that iterative linear regression yields a smaller square error than robust regression although this method is only approximative. Both methods yield results outperforming a first manual setting, and for both methods, basically the same set of non-zero weights remain.

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Four-dimensional supersymmetric N = 1 vacua of type IIB supergravity are elegantly described by generalized complex geometry. However, this approach typically obscures the SL(2, R) covariance of the underlying theory. We show how to rewrite the pure spinor equations of Grana, Minasian, Petrini and Tomasiello (hep-th/0505212) in a manifestly SL(2,R) covariant fashion. Solutions to these equations fall into two classes: "charged" solutions, such as those containing D5-branes, and "chargeless" solutions, such as F-theory solutions in the Sen limit and AdS4 solutions. We derive covariant supersymmetry conditions for the chargeless case, allowing general SU(3)xSU(3) structure. The formalism presented here greatly simplifies the study of the ten-dimensional geometry of general supersymmetric compactifications of F-theory.

description: The clinical management of asthma involves treatment with inhaled corticosteroids (ICS) and long-acting β2-adrenoceptor agonists (LABAs). Regulator of G-protein signalling (RGS) 2 inhibits signalling from Gq protein-coupled receptors. In humans, combinations of a glucocorticoid and a LABA synergistically enhanced the expression of RGS2. In mice, 3 weeks of HDM challenge or 30 min of LPS challenge reduced lung function and induced airways inflammation. Compared to wild-type, Rgs2-/- mice showed significantly increased airways resistance and reduced compliance, in both HDM- and LPS-challenges. There was no difference between wild-type and Rgs2-/- mice in HDM-induced and LPS-induced inflammation. There was a trend towards increased inflammatory cell counts in the BALF of Rgs2-/- compared to wild-type. There was a trend towards increased expression for many HDM-induced cytokines/chemokines in Rgs2-/-. There was no difference between wild-type and Rgs2-/- mice in LPS-induced expression of cytokines/chemokines. These data show Rgs2 is bronchoprotective in HDM-induced inflammation and suggest a modest anti-inflammatory role. Rgs2 is bronchoprotective in LPS-induced inflammation, but more studies are required to address a possible anti-inflammatory role. If applicable to humans, these data suggest that therapeutics, for example ICS/LABA combination therapies, which are designed to maximize RGS2 expression, will be beneficial for asthma control and management.

Remarks. Gomes Corrêa (1972) in her list on decapods of the Abrolhos Archipelago listed A. armillatus and A. heterochaelis. However, the record of A. heterochaelis from this archipelago was based on Smith (1869) and should be therefore attributed to A. armillatus (Christoffersen 1984).
Alpheus armillatus is a species complex that includes at least seven species in the western Atlantic (A. Anker, personal communication; see also Mathews 2006). The identity of the Brazilian material, including the actual number of species present on the Brazilian coast, remains unknown.

description: We propose a statistical modeling technique, called the Hierarchical Association Rule Model (HARM), that predicts a patient's possible future medical conditions given the patient's current and past history of reported conditions. The core of our technique is a Bayesian hierarchical model for selecting predictive association rules (such as "condition 1 and condition 2 $\rightarrow$ condition 3") from a large set of candidate rules. Because this method "borrows strength" using the conditions of many similar patients, it is able to provide predictions specialized to any given patient, even when little information about the patient's history of conditions is available.

description: The site of construction is considered a resource like any other resource in a project and, as such, has to be managed in order to have maximum benefit. The placement of temporary facilities on-site is a key site-layout planning task. In dynamic congested sites, the locations of temporary facilities are changed frequently due to very limited space. This research proposes a model to help in the planning of an efficient dynamic-site layout. The model consists of commercial software programs which have been integrated to offer a complete solution. The problems associated with the planning of a dynamic, congested construction site are analyzed and the influencing factors for site layout are illustrated. The Unified Modeling Language (UML) is introduced to illustrate the model’s structure, its components and the interactions among them. The UML describes the activities during the model’s implementation, where the decisions must be made, and those involved in decision making. The computer model is divided into two main sections: the first uses the special purpose simulation (Simphony) to help the planner identify the required number of temporary facilities. The second section provides the effective placement of the temporary facilities on the construction site, for which Microsoft Access maintains the information libraries for the construction site and the required temporary facilities. Fuzzy applications are developed to assess the weight parameter for the relation between the temporary facilities. The Visual Basic for Application (VBA) module is implemented to transfer construction-site information between AutoCAD, Simphony and Microsoft Access.. For optimization research, Genetic Algorithm (GA) is used to find the near-best solution for placing the temporary facilities at site where the weight between temporary facilities is used as the fitness function. The module feature in the Microsoft access is used to implement the Genetic Algorithm which facilitates the connection between the GA and Microsoft Access libraries .The final chosen solution is shown on the AutoCAD site-layout drawing. Different scenarios can be produced to allow the planner to choose the one which adopts the most requirements. The model has a highly-usable interface, with the objectives that no special training will be required.

description: Four archipelagos in the South China Sea are territorially disputed: the Paracel, Spratly, and Pratas Islands, and Macclesfield Bank. The People’s Republic of China and Republic of China’s claims are embodied by a nine-dashed U-shaped boundary line originally drawn in an official Chinese map in 1948, which encompasses most of the South China Sea. Neither side has clarified what the line represents. Using ancient Chinese maps and texts, archival documents, relevant treaties, declarations, and laws, this thesis will conclude that it is best characterized as an islands attribution line, which centres the claim simply on the islands and features themselves. It does not delineate a historic rights waters zone, which confer certain exploitation and regulation privileges over all of the waters the line contains on the basis of historic Chinese dominance. The period of time examined is from 1644 to 2013; from the Qing Dynasty to the present.

description: The physical relationship between low-excitation gas filaments at ~10^4 K, seen in optical line emission, and diffuse X-ray emitting coronal gas at ~10^7 K in the centers of many galaxy clusters is not understood. It is unclear whether the ~10^4 K filaments have cooled and condensed from the ambient hot (~10^7 K) medium or have some other origin such as the infall of cold gas in a merger, or the disturbance of an internal cool reservoir of gas by nuclear activity. Observations of gas at intermediate temperatures (~10^5-10^6 K) can potentially reveal whether the central massive galaxies are gaining cool gas through condensation or losing it through conductive evaporation and hence identify plausible scenarios for transport processes in galaxy cluster gas. Here we present spectroscopic detection of ~10^5 K gas spatially associated with the H-alpha filaments in a central cluster galaxy, M87 in the Virgo Cluster. The measured emission-line fluxes from triply ionized carbon (CIV 1549 A) and singly ionized helium (HeII 1640 A) are consistent with a model in which thermal conduction determines the interaction between hot and cold phases.

description: The manifestation of the spin-wave interaction in the low-temperature series of the partition function has been investigated extensively over more than seven decades in the case of the three-dimensional ferromagnet. Surprisingly, the same problem regarding ferromagnets in two spatial dimensions, to the best of our knowledge, has never been addressed in a systematic way so far. In the present paper the low-temperature properties of two-dimensional ideal ferromagnets are analyzed within the model-independent method of effective Lagrangians. The low-temperature expansion of the partition function is evaluated up to two-loop order and the general structure of this series is discussed, including the effect of a weak external magnetic field. Our results apply to two-dimensional ideal ferromagnets which exhibit a spontaneously broken spin rotation symmetry O(3) $\to $ O(2) and are defined on a square, honeycomb, triangular or Kagomé lattice. Remarkably, the spin-wave interaction only sets in at three-loop order. In particular, there is no interaction term of order $T^3$ in the low-temperature series for the free energy density. This is the analog of the statement that, in the case of three-dimensional ferromagnets, there is no interaction term of order $T^4$ in the free energy density. We also provide a careful discussion of the implications of the Mermin-Wagner theorem in the present context and thereby put our low-temperature expansions on safe grounds.

The Effectiveness of Large Scale Transformational Change Across a School District

description: This research describes characteristics of large-scale organizational change in one mid-sized school district in Alberta, Canada. The period of the case study was from 2007–2011 within a district that was showing signs of significant change in operations. A review of two public large sets of data, coupled with external interest in the work of the district, confirmed that change was occurring of some type and to some degree. An outside researcher conducted interviews with school-based and district leaders to identify what characteristics and actions had been put in place and to describe if they were successful. Research participants identified four characteristics of large-scale change that were impactful: a collaboratively built and universally administered strategic plan, a focus on building individual capacity through a professional learning model, the establishment of collaborative structures to co-create the future, and the fostering of high organizational trust. Participants also identified accountability and communication structures as important. Regardless of whether readers are convinced that the district fundamentally changed its practice, described as second-order change, the characteristics identified by the leaders as impactful for the attempted change are important. At a time when there is growing consensus to modernize antiquated paradigms of public education delivery and structure, these findings can provide a structure of what to do and what to avoid when embarking upon this type of change. Change of this magnitude is not for the faint of heart, especially given that all change characteristics are interdependent and must be initiated at the same time, which is vastly different from 20th century incremental change in education.
Stability of switched systems with switching delay : application to remote operation of aircraft under distributed control

description: Unmanned aerial vehicles are becoming more and more useful tools for not only the military, but law enforcement, search and rescue and scientific data collection. With the advent of inexpensive and reliable wireless communication, remote operators are now able to control fleets of UAVs cooperating towards the accomplishment of their tasks. As the complexity and size of these fleets increase, distributed control methods are needed -- large fleet sizes will lead to intractable centralized problems. Furthermore, UAVs, like most aircraft, are inherently hybrid systems, combining both discrete and continuous dynamics. This thesis attempts to combine hybrid and distributed control theories in a way useful for the operation of UAVs, while taking communication delays inherent to a remote operator into account. Specifically, we consider the stability of block upper-triangular switched linear systems with switching delay, when switching between stable modes. We show that the problem of proving globally uniformly asymptotic stability (GUAS) of a block upper-triangular switched linear system can be reduced to proving GUAS for each of its block diagonal subsystems. This allows for a scalable LMI-based computational test for GUAS under arbitrary switching whose complexity depends linearly on the number of block diagonal elements of the system. In cases for which the system is not GUAS under arbitrary switching, we partition the state space into regions in which switching will preserve GUAS despite a delay between the state measurements and switching time. This is accomplished by adding a delay buffer to standard Piecewise Lyapunov based partitions. Additionally, we show that the effect of the delay buffer on the standard Piecewise Lyapunov based partitions asymptotically approaches zero. Although we tailor these results to block upper-triangular switched linear systems, they are applicable to any switched linear system with switching delay. These results are then extended to nonlinear switched systems. We apply our results to the control of a formation of vehicles under supervisory discrete control, and to switched systems under remote control. We then finish by addressing the issue of interface design for continuous systems under shared control, motivated by applications to pilot-automation interactions.

description: This study compared the bacterial and archaeal communities between a natural peatland and a peatland affected by water table drawdown along a microtopographic position and depth gradient. Peat physicochemical properties, carbon flux and potential CO2 and CH4 production as well as CH4 oxidation were measured to determine which factors affect microbial composition and diversity. Bacterial and archaeal communities were described by targeting the 16S rRNA gene using pyrosequencing. Physicochemical parameters measured included pH, peat temperature, humification, acetate, formate, sulfate, nitrite and nitrate. The most predominant methanotroph genus was Methylocella and the most predominant methanogen group was Methanomicrobiales Rice Cluster II. Diversity indices show humification and position relative to the water table as significant drivers affecting microbial diversity and richness. The control and drained sites differed significantly regarding the physicochemical influences on microbial relative abundance, however, pH affected methanotroph and methanogen relative abundance at both peatland sites.

description: We report on the design of a segmented linear Paul trap for optical clock applications using trapped ion Coulomb crystals. For an optical clock with an improved short-term stability and a fractional frequency uncertainty of 10^-18, we propose 115In+ ions sympathetically cooled by 172Yb+. We discuss the systematic frequency shifts of such a frequency standard. In particular, we elaborate on high precision calculations of the electric radiofrequency field of the ion trap using the finite element method. These calculations are used to find a scalable design with minimized excess micromotion of the ions at a level at which the corresponding second- order Doppler shift contributes less than 10^-18 to the relative uncertainty of the frequency standard.
