AbstractThe depth at which pitfall traps were sunk into the ground and the resulting catches of epigaeic Carabidae (Coleoptera) and Staphylinidae (Coleoptera) assemblages in subhygric to hydric ecosites with very deep organic soil layers was investigated in the upper foothills ecoregion of Alberta, Canada. Traps were installed at seven sites, with six surface traps (the pitfall trap lip <5 cm below soil surface) and six deep traps (the pitfall trap lip >20 cm below soil surface) at each site. A total of 5289 beetles representing 75 taxa were collected. There were no significant effects of trap depth on catch. Rarefaction estimates of species diversity were higher in surface pitfall traps for both taxa. The similarity of pooled catches between deep and surface traps was on average 75%, suggesting that both trap types were collecting similar faunas. We found no advantage to using deep pitfall traps in addition to surface traps to sample the epigaeic fauna of wet forest stands and peatlands.

The effect of AlGaN surface traps on breakdown voltage VB and drain current collapse in AlGaN/GaN high electron mobility transistors (HEMTs) were investigated using experimental measurement and numerical simulation. The drain current transient due to surface traps was systematically measured and analyzed, and the activation energy of a surface trap was evaluated as approximately 0.7 eV. Results from the device simulation of VB in HEMTs were in good agreement with the experimental results when assuming surface traps. The results indicate that surface traps increase VB, and induce a crucial current collapse.

AbstractThe efficacy of pheromone traps is affected by trap placement and pest biology, as well as by the trap and lure design. We evaluated the effect of trap height and placement in relation to surfaces on tobacco moth catches using release-capture experiments. Six traps were mounted vertically in a 9 × 15 × 4.2-5.8 m shed on a wall at heights of 0, 1, 2, 3, 4 and 5 m. More catches were obtained near the ceiling and at 1 m above the floor in the dark. Catches at 1 m were negligible when light shone through the upper windows. In a 42.3 × 36.5 × 4 m tobacco warehouse, the respective efficacies of aerially suspended traps and surface-mounted traps were examined. The number of catches obtained using traps mounted on pillars was significantly higher than that obtained in traps suspended from poles. These results suggest practical considerations for monitoring in warehouses. We recommend eliminating any night lighting and placing traps on surfaces, such as walls and stored commodities, at higher positions that are within reach (1 m) to facilitate convenient inspection.

The major challenges in trapped-ion quantum computation are to scale up few-ion experiments to many qubits and to improve control techniques so that quantum logic gates can be carried out with higher fidelities. This thesis re- ports experimental progress in both of these areas. In the early part of the the- sis we describe the fabrication of a surface-electrode ion trap, the development of the apparatus and techniques required to operate it and the successful trap- ping of 40Ca+ ions. Notably we developed methods to control the orientation of the principal axes and to minimise ion micromotion. We propose a repumping scheme that simplifies heating rate measurements for ions with low-lying D levels, and use it to characterise the electric field noise in the trap. Surface-electrode traps are important because they offer a route to dense integration of electronic and optical control elements using existing microfabrication technology. We explore this scaling route by testing a series of three traps that were microfabricated at Sandia National Laboratories. Investigations of micromotion and charging of the surface by laser beams were carried out and improvements to future traps are suggested. Using one of these traps we also investigated anomalous electrical noise from the electrode surfaces and discovered that it can be reduced by cleaning with a pulsed laser. A factor of two de- crease was observed; this represents the first in situ removal of this noise source, an important step towards higher gate fidelities. In the second half of the thesis we describe the design and construction of an experiment for the purpose of replacing laser-driven multi-qubit quantum logic gates with microwave-driven ones. We investigate magnetic-field-independent hyperfine qubits in 40Ca+ as suitable qubits for this scheme. We make a design study of how best to integrate an ion trap with the microwave conductors required to implement the gate and propose a novel integrated resonant structure. The trap was fabricated and ions were successfully loaded. Single-qubit experiments show that the microwave fields above the trap are in excellent agreement with software simulations. There are good prospects for demonstrating a multi-qubit gate in the near future. We conclude by discussing the possibilities for larger-scale quantum computation by combining microfabricated traps and microwave control.

Trapped ions are a promising approach to quantum computation. This approach uses a qubit state which is the atomic state and quantum motional state of a trapped ion to encode information, and uses laser-ion interactions to manipulate the qubit state. A major obstacle to the realization of a practical ion trap quantum computer is decoherence. In trapped ion quantum computation experiments, decoherence is dominated by the uncontrolled heating of ion motional states. In this thesis, we present the detailed microfabrication of several series of surface electrode linear Paul traps made from different electrode materials, followed by the ion motional heating experiment results for these traps. We demonstrate that the ion motional heating strongly depends on fabrication process. In particular, we explore how grain size and grain orientation affect the ion motional heating rate. This thesis is divided into two parts. In the first part, we describe the fabrication of gold, silver, aluminum and niobium traps from different processes, which results in various surface morphologies and grain structures. Ion motional heating rate measurements are then conducted both at cryogenic temperatures and at room temperature. We employ a physical model based on the fluctuating patch potential theory to explain the ion heating behavior. We use gold traps to study the temperature and frequency dependence of the ion heating. We use aluminum traps to study the ion heating dependence on the amorphous dielectric layer. And we use silver traps to study the ion heating dependence on the grain structure. These results suggest that excess ion heating could possibly be suppressed by suitable fabrication selection. In the second part, we present the process of using SU8 to fabricate a multilayer surface electrode point Paul trap, which has the advantage of allowing ion height variation within the same trap and enables testing of the distance dependence of ion heating.

We fabricated superconducting surface electrode ion traps with integrated microwave coplanar waveguides using direct-write optical lithography and a niobium on sapphire process. We then tested these traps in a closed cycle cryostat and used 28 mW of microwave power to excite rotational transitions of trapped strontium chloride molecular ions. We expected that driving these rotational transitions would heat a co-trapped strontium atomic ion cloud. However, we did not see this heating and we must conduct further experiments.

Ion traps provide an excellent tool for controlling and observing the state of a single trapped ion. For this reason, ion traps have been proposed as a possible system for large-scale quantum computation. However, many obstacles must be overcome before quantum computing can become a reality. In particular, perturbations in the electric field due to noise and electrode charging must be reduced to increase coherence of the motional quantum state. Gold has been a popular choice in the past due to its inert properties; however, it is undesirable due its incompatibility with CMOS technology. This has led to increased research into alternative CMOS-compatible materials, such as aluminum and copper. This thesis presents measurements of electric field noise and light-induced charging in aluminum, copper, and gold surface electrode traps. In addition, the effect of oxide growth on field noise and electrode charging is explored by controlling the thickness of aluminum oxide on several aluminum traps. The measurements show that electric field noise can be suppressed in aluminum traps to approximately 10-18 V2 cm-2 Hz-1, matching the noise exhibited in gold traps, and that copper traps exhibit noise within an order of magnitude of that in aluminum and gold. However, the natural oxide of aluminum poses many problems towards high-performance aluminum ion traps. The electric field noise is shown to be strongly dependent on the oxide thickness, increasing the noise by a factor of about 10 until saturation at a thickness of 13 nm. Charging of surface electrodes is shown to be highly dependent upon the material, but the model presented does not match the experimental data and is found to be incomplete. These results indicate that ion traps made out of CMOS-compatible materials can perform as well as more traditional traps fabricated from gold with respect to heating and charging as long as methods are developed for controlling oxide growth.

Trapped cold molecules open the possibility of studying ultracold chemistry and astrophysical processes in laboratory settings. Their rich internal structure also makes them suitable for quantum information manipulation or for tests of fundamental laws of nature. These experiments require precise control over the molecular internal degrees of freedom. There are few present proposals for trapping and cooling molecules. One proposal is based on confining neutral polar molecules in DC Stark shift traps, but this approach presents some issues. An attractive alternative is to confine polar molecular ions in RF Paul ion traps, which is the focus of this thesis. The objectives here are to develop the theoretical models and to devise the experimental components and methods to investigate the coupling of polar molecular ions' rotational states to the microwave radiation. The new approach presented here is based on co-trapping Sr+ atomic ions together with SrCl+ molecular ions in a cryogenic surface electrode RF ion trap and on using the coupling of the molecular ion's rotational states to an integrated superconducting microwave line or cavity either as a cooling method or for precise rotational spectroscopy. The first part of the thesis describes two theoretical methods for observing the coupling of the microwave radiation to the rotational levels of a molecule. The first method proposed is based on the enhancement of the molecular rotational transition rates by the co-trapped molecular-atomic ions Coulomb collisions. The second method is based on microwave cavity assisted heating or cooling of the molecular ions. The second part of the thesis presents the development of a cryogenic surface electrode RF ion trap with an integrated microwave transmission line/resonator. The ion trap is operated in a 4.2 K closed cycle cryostat.

Movement-independent trapping mechanisms are based on stickiness, slipperiness, and direction-dependent mechanical obstruction. Here, the implementation of these principles in flypaper, pitfall, and eel traps is discussed in the light of recent scientific advances. The chemical composition and rheological properties of trapping fluids, and the (micro-) morphology of trapping surfaces, are related to their functions. Recent discoveries including the role of surface wettability in prey capture by pitcher plants are presented, and the ecological implications of temporal variations of trap performance and promising directions for future research are discussed.

This chapter presents the thesis, structure, and philosophy of the book. Using the author’s Romanian excavations as a start, the chapter reviews the state of knowledge about pits and pit-houses in Neolithic Europe, critically reviews the debate over structured deposition (and suggests that the actions of breaking the surface of the ground—that is, digging—have not featured in previous work on the topic), defines art/archaeology (as an innovative way to provide original thought on the topic), and then justifies the book’s approach and unusual content and layout. The argument made is both that a new way to engage the archaeological object is through a new trans-disciplinary approach that juxtaposes past and present, archaeology and art, and that the reader will gain much from examining the Neolithic and other periods through the processes and consequences of cutting surfaces.

In a world that is responding to ever-changing ideas and expressions of gender, this book adds new insights on transgender children and the parents who support them. Drawing on in-depth interview data with more than fifty parents, the book examines parents’ shifting understandings of their children’s gender and how they come to help their children make sense of their identities and their bodies. Throughout these processes, the book shows that parents’ meaning-making and decision-making often challenge LGBT rights discourses, as well as queer political tenets, in unexpected ways. These dynamics surface in three key areas: (1) gender and sexuality, (2) the gender binary, and (3) the body. Throughout parents’ understandings, gender identity and sexual orientation do not always present as radically separate aspects of the self, but are more fluid and open to reconsideration, given new cultural contexts, opportunities, and phases of the life course. And despite increasing cultural visibility around nonbinary identities, “gender-expansive” child-rearing often looks, fundamentally, very binary and gender-stereotypical, per the children’s own assertions and expressions. Lastly, parents often utilize highly medicalized understandings of transgender embodiment, which nevertheless resonate with some children’s sensibilities. Altogether, these families depart from conventional understandings of gender, sexuality, and the binary, but in ways that prioritize child-centered shifts, meanings, and parenting models, not necessarily LGBTQ politics or paradigms. This marks new ground for understanding the mechanisms and parameters of the (trans)gender change afoot.

The Global Virome: The viruses have a global distribution, phylogenetic diversity, and host specificity. They are obligate intracellular parasites with single- or double-stranded DNA or RNA genomes, and afflict bacteria, plants, animals, and human population. The infecting virus binds to receptor proteins on the host cell surface, followed by internalisation, replication, and cell lysis. Further, trans-species interactions of viruses with bacteria, small eukaryotes and host are linked with various zoonotic viral diseases and disease progression.

AbstractAssessments of aquatic ecosystem health rely increasingly on biological indicators such as fish community structure, but national approaches differ. To use bioindicators efficiently and to allow cross-country comparisons, standardized tools and methods are required. Within this study, currently applied procedures for stream ecosystem assessment in China and Germany are summarized and active and passive fish sampling methodologies used in both countries are investigated. The methodological comparison was based on the results of a joint Chinese German workshops within the SINOWATER project in 2016. A joint sampling campaign was then conducted in 2017 at 6 representative sites within 70 km of the Fan River, a tributary to the Liao River System in Liaoning province, China. Active methods comprised single-pass electrofishing methods as typically applied in Germany and China as well as seining. As passive methods, common minnow traps, gill-netting and longline-fishing were used. To allow the comparability between methods, a standardized sampling design comprising several replicates at each site was chosen, covering a range of different ecological stream conditions. By comparison of the different fishing methodologies, electrofishing yielded the best overall results to assess fish biodiversity in terms of species abundance, richness and catch per unit effort. Differences in the effectiveness of the different electrofishing approaches mostly depended on the power source used. To cover the full spectrum of the fish community and to detect very rare species, a combination of different active and passive methods was most useful. If electrofishing is the method of choice, it is very important to adjust the gear power to river specific conditions such as flow, size and depth. The results of this joint Chinese-German study may aid in the selection of suitable sampling methods for fish community assessments in the future.

This paper describes the theory and experiments involve in the capture of bubbles onto a patterned surface. Guided by surface free energy, bubbles can automatically attach to the energetically favorable locations (bubble-traps) and align into bubble arrays. Bubble capturing potential φbc is proposed as the quantity to evaluate the surface’s “affinity” for bubbles. A bubble-trap can therefore be viewed as an area with locally maximum positive φbc. Two types of bubble-traps are proposed and evaluated. Type I bubble-traps are hydrophobic patterns on a hydrophilic flat surface. Type II bubble-traps are concave conic pits surrounded by a hydrophilic flat surface. Simulation of bubble capturing potential φbc explains the bubble-capturing behavior for both cases and predicts a better performance for type II bubble-traps. Experiments agree well with the theoretical prediction and suggest promising applications.

A model was generated to evaluate the performance of the cesium trap system used as part of the BN-350 nuclear reactor decommissioning effort in Aktau, Kazakhstan. A series of cesium traps were designed to remove cesium from the reactor primary circuit sodium and piping to minimize personnel radiological exposure while draining and disposing of the sodium during subsequent decommissioning activities. Cesium was trapped by extracting sodium from the primary circuit, passing it through a block of reticulated vitreous carbon (RVC), and returning the cleaned sodium to the primary circuit. Cesium has a strong affinity for adsorbing onto the surface of carbon and RVC in particular has been proven to be an effective cesium collecting material. A model was created to predict and help explain the performance of the system during operation. The model is effectively split into two components, the reactor primary system component and the cesium trap RVC component. The temperature dependent parameters governing the behavior of the system were continuously updated. The model output effectively described the behavior observed during the operation of the first three cesium traps (the final four traps were used to clean a variety of ancillary system whose initially conditions were not well known and, consequently, did not lend themselves to being modeled). The defining system operating conditions were the primary sodium temperature of approximately 290 °C, trap RVC temperatures range of 150 °C to 260 °C, and dissolved cesium concentrations in the primary sodium ranging from 7.2×10−3 Ci/kg to 2.4×10−4 Ci/kg.

Therapeutic antibodies (Abs) are a rapidly growing and economically promising biotechnological research area. Therapeutic Ab production typically involves screening large numbers of Ab-secreting cells (ASCs) in order to identify those producing Abs targeting a specific antigen (Ag) with the highest affinity; a process often requiring weeks to complete. We are contributing to a multidisciplinary project focused upon the development of an immunobiosensing array ultimately intended to directly monitor the Ag-specific Ab production by thousands of ASCs on a single slide in real-time. Each ASC shall be microfluidically guided and trapped near a surface plasmon (SP) resonant nanohole array sensor so as to detect the binding of secreted Abs to Ag immobilized onto the sensor’s surface. This paper presents the initial progress of our contribution to this project: the development of polymeric microfluidic devices to guide and trap large ASC populations within arrays of single-cell traps. More specifically, this paper presents several different polymer-based microfluidic trapping devices, based upon perfusive flow-through cell traps and microwells which trap settling cells, which have been evaluated using COMSOL® simulations and tested using microsphere- and cell-based flow experiments. Our initial results are promising, and verify the functionality of our microfluidic cell trap designs.

This interdisciplinaray work combines expertise in engineering and entomology in Israel and the US, to develop an acoustic trap for mate-seeking female medflies. Medflies are among the world's most economically harmful pests, and monitoring and control efforts cost about $800 million each year in Israel and the US. Efficient traps are vitally important tools for medfly quarantine and pest management activities; they are needed for early detection, for predicting dispersal patterns and for estimating medfly abundance within infested regions. Early detection facilitates rapid response to invasions, in order to contain them. Prediction of dispersal patterns facilitates preemptive action, and estimates of the pests' abundance lead to quantification of medfly infestations and control efforts. Although olfactory attractants and traps exist for capturing male and mated female medflies, there are still no satisfactorily efficient means to attract and trap virgin and remating females (a significant and dangerous segment of the population). We proposed to explore the largely ignored mechanism of female attraction to male song that the flies use in courtship. The potential of such an approach is indicated by studies under this project. Our research involved the identification, isolation, and augmentation of the most attractive components of male medfly songs and the use of these components in the design and testing of traps incorporating acoustic lures. The project combined expertise in acoustic engineering and instrumentation, fruit fly behavior, and integrated pest management. The BARD support was provided for 1 year to enable proof-of-concept studies, aimed to determine: 1) whether mate-seeking female medflies are attracted to male songs; and 2) over what distance such attraction works. Male medfly calling song was recorded during courtship. Multiple acoustic components of male song were examined and tested for synergism with substrate vibrations produced by various surfaces, plates and loudspeakers, with natural and artificial sound playbacks. A speaker-funnel system was developed that focused the playback signal to reproduce as closely as possible the near-field spatial characteristics of the sounds produced by individual males. In initial studies, the system was tasted by observing the behavior of females while the speaker system played songs at various intensities. Through morning and early afternoon periods of peak sexual activity, virgin female medflies landed on a sheet of filter paper at the funnel outlet and stayed longer during broadcasting than during the silent part of the cycle. In later studies, females were captured on sticky paper at the funnel outlet. The mean capture rates were 67 and 44%, respectively, during sound emission and silent control periods. The findings confirmed that female trapping was improved if a male calling song was played. The second stage of the research focused on estimating the trapping range. Initial results indicated that the range possibly extended to 70 cm, but additional, verification tests remain to be conducted. Further studies are planned also to consider effects of combining acoustic and pheromonal cues.
