description: We describe a method to fabricate clean suspended single-wall carbon nanotube (SWCNT) transistors hosting a single quantum dot ranging in length from a few 10s of nm down to $\approx$ 3 nm. We first align narrow gold bow-tie junctions on top of individual SWCNTs and suspend the devices. We then use a feedback-controlled electromigration to break the gold junctions and expose nm-sized sections of SWCNTs. We measure electron transport in these devices at low temperature and show that they form clean and tunable single-electron transistors. These ultra-short suspended transistors offer the prospect of studying THz oscillators with strong electron-vibron coupling.

description: We discuss the Hamiltonian dynamics for cosmologies coming from Extended Theories of Gravity. In particular, minisuperspace models are taken into account searching for Noether symmetries. The existence of conserved quantities gives selection rule to recover classical behaviors in cosmic evolution according to the so called Hartle criterion, that allows to select correlated regions in the configuration space of dynamical variables. We show that such a statement works for general classes of Extended Theories of Gravity and is conformally preserved. Furthermore, the presence of Noether symmetries allows a straightforward classification of singularities that represent the points where the symmetry is broken. Examples of nonminimally coupled and higher-order models are discussed.

description: Mobile Ad hoc Networks (MANETS) are transient networks of mobile nodes, connected through wireless links, without any fixed infrastructure or central management. Due to the self-configuring nature of these networks, the topology is highly dynamic. This makes the Ad Hoc Routing Protocols in MANETS highly vulnerable to serious security issues. In this paper, we survey the common security threats and attacks and summarize the solutions suggested in the survey to mitigate these security vulnerabilities.

description: We consider the stochastic ranking process with space-time dependent jump rates for the particles. The process is a simplified model of the time evolution of the rankings such as sales ranks at online bookstores. We prove that the joint empirical distribution of jump rate and scaled position converges almost surely to a deterministic distribution, and also the tagged particle processes converge almost surely, in the infinite particle limit. The limit distribution is characterized by a system of inviscid Burgers-like integral-partial differential equations with evaporation terms, and the limit process of a tagged particle is a motion along a characteristic curve of the differential equations except at its Poisson times of jumps to the origin.

description: Plastics are a source of pollution throughout their entire life cycle from extraction, involving releases of greenhouse gases (GHGs), micro- and nanoplastic (MNPs) contamination, and hazardous chemicals such as endocrine disruptors, causing exposure to humans and the environment. This policy brief focuses on plastic chemicals of concern, which spans from extraction of feedstocks, through conversions to monomers, polymerization, formulation, and molding, use, management, and removal and remediation. Plastics can deposit chemical contaminants over time into everything, such as food, water, soil, clothing, air and living organisms, including humans.

description: A semigroup is \emph{amiable} if there is exactly one idempotent in each $\mathcal{R}^*$-class and in each $\mathcal{L}^*$-class. A semigroup is \emph{adequate} if it is amiable and if its idempotents commute. We characterize adequate semigroups by showing that they are precisely those amiable semigroups which do not contain isomorphic copies of two particular nonadequate semigroups as subsemigroups.

description: Many search strategies for the Standard Model Higgs boson apply specific selection criteria on hadronic jets observed in association with the Higgs boson decay products, either in the form of a jet veto, or by defining event samples according to jet multiplicity. To improve the theoretical description of Higgs-boson-plus-jet production (and the closely related Higgs boson transverse momentum distribution), we derive the two-loop QCD corrections to the helicity amplitudes for the processes $H \to ggg$ and $H\to q \bar q g$ in an effective theory with infinite top quark mass. The helicity amplitudes are extracted from the coefficients appearing in the general tensorial structure for each process. The coefficients are derived from the Feynman graph amplitudes by means of projectors within the conventional dimensional regularization scheme. The infrared pole structure of our result agrees with the expectation from infrared factorization and the finite parts of the amplitudes are expressed in terms of one- and two-dimensional harmonic polylogarithms.

Activity restart - a key to explaining the morphology of J1211+743

Year: 2012
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: J1211+743 is a giant radio galaxy with a one-sided jet and two asymmetric lobes, one of which is of Fanaroff-Riley (FR) type II with a hotspot and the other is a diffuse relic devoid of a hotspot. The jet points towards the latter lobe, which is difficult to explain in a standard way within the double-lobed radio source paradigm. Here, I propose to assume that the nucleus of J1211+743 has undergone a re-ignition of activity and its lobes, presumably both originally of FR II type, represent an earlier active phase, while the jet represents the current one. The asymmetry of the lobes is a consequence of the orientation of the source combined with an activity switch-off that occurred between two active periods. The relic lobe is on the near side with regard to the observer, whereas the radiation from the far-side lobe arrives significantly later owing to its longer distance to the observer. The far-side lobe is thus perceived to have not yet decayed. On the other hand, the jet behaves in a standard way, i.e. its projected orientation reflects the near side of the source. Hence, we are able to explain why the location of the relic lobe correlates with the direction of the jet.

Cryopreservation and transplantation of ovarian tissue in Japanese quail (Coturnix japonica)
Creators: name: Liu, Jianan
Publisher: name: University of British Columbia
Year: 2010

description: Cryopreservation of avian genetic material is limited in terms of practicality, efficiency, and success. The complex structure of female gametes in birds makes the application of cryopreservation extremely difficult, and the fertilization obtained from frozen/thawed poultry semen is low and unpredictable. Embryonic germ cells can be frozen and used to generate germline chimeras, but the low efficiency and complex procedures limit these techniques for genetic conservation. The techniques of transplantation of ovaries and testes in newly hatched chicks have recently been developed and donor-derived offspring could be efficiently produced from cryopreserved testicular transplants and from fresh ovarian tissue transplants in chicken. This success in chicken gonadal transplantation provides an effective method for recuperating live birds from cryopreserved gonadal tissue. Research efforts are needed to develop cryopreservation technique for ovarian tissues and further apply cryopreservation and transplantation to the other avian species. The Japanese quail is a much smaller bird than the chicken and has a slightly different reproductive biology. Preliminary research has demonstrated that live offspring could be obtained from fresh ovarian grafts in one-week old quail. Using the Japanese quail as a model, the objective of this thesis is to develop a feasible and reliable cryopreservation technique for ovarian tissue and to recover it by subsequent transplantation, with the hope that this protocol of cryopreservation and transplantation can attribute to female germplasm conservation for other avian species in the future. Both slow-freezing and vitrification were used as cryopreservation approaches in this study. The efficiency was evaluated at three levels: cell viability, tissue histology and the recovery of the donor fertilities after surgical transplantation. Donor-derived offspring were obtained from the ovarian tissues that had been cryopreserved by either slow-freezing or vitrification. The vitrification protocol used in this study showed better outcomes at each level of evaluation. Thus the current study verified that the function of ovarian tissue in an avian species can be successfully preserved at subzero temperatures and recovered by transplantation. The vitrification protocol is recommended for future use concerning its low cost, high efficiency and overall simplicity in optimization to benefit more avian species.

description: We investigate the gain bandwidth and wavelength-tuning range of an erbium-doped fluoride fibre amplifier. The presented experimental setup consisted of a widely wavelength-tunable optical parametric oscillator (OPO), which was amplified in a single-stage Er-doped fluoride fibre amplifier. The OPO laser provided seed pulses with a pulse width of 5.2 ns and a repetition rate of 10 kHz. The fibre section consisted of 2.2 m of double-clad, single-mode fibre with a doping concentration of 7 mol%. Wavelength-tuning was analysed at gain values of up to 26 dB and amplified pulse energies of up to 37.4 μJ. Using this setup, we demonstrate continuous wavelength tuning of more than 100 nm, covering the wavelength range from 2712 nm to 2818 nm.

Sensitivity of the correlation between the depth of shower maximum and the muon shower size to the cosmic ray composition

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The composition of ultra-high energy cosmic rays is an important issue in astroparticle physics research, and additional experimental results are required for further progress. Here we investigate what can be learned from the statistical correlation factor r between the depth of shower maximum and the muon shower size, when these observables are measured simultaneously for a set of air showers. The correlation factor r contains the lowest-order moment of a two-dimensional distribution taking both observables into account, and it is independent of systematic uncertainties of the absolute scales of the two observables. We find that, assuming realistic measurement uncertainties, the value of r can provide a measure of the spread of masses in the primary beam. Particularly, one can differentiate between a well-mixed composition (i.e., a beam that contains large fractions of both light and heavy primaries) and a relatively pure composition (i.e., a beam that contains species all of a similar mass). The number of events required for a statistically significant differentiation is ~ 200. This differentiation, though diluted, is maintained to a significant extent in the presence of uncertainties in the phenomenology of high energy hadronic interactions. Testing whether the beam is pure or well-mixed is well motivated by recent measurements of the depth of shower maximum.

A simple nonlinear equation for structural relaxation in glasses

description: A wide range of glassy and disordered materials exhibit complex, non-exponential, structural relaxation (aging). We propose a simple nonlinear rate equation dδ/dt = a [1-exp (bδ)], where 'δ' is the normalized deviation of a macroscopic variable from its equilibrium value, to describe glassy relaxation. Analysis of extensive experimental data shows that this equation quantitatively captures structural relaxation, where 'a' and 'b' are both temperature-, and more importantly, history-dependent parameters. This analysis explicitly demonstrates that structural relaxation cannot be accurately described by a single non-equilibrium variable. Relaxation rates extracted from the data imply the existence of cooperative rearrangements on a super-molecular scale.

description: Adventitious root (AR) formation is the basis of vegetative propagation in rose, be it via stem cuttings or via stenting. During this process, wounding plays a pivotal role since cell reprogramming takes place at the tissue adjacent to the wound. We investigated the effects of wounding on AR formation on leafy single-node stem cuttings of the rose rootstock R. canina ‘Pfänder’ (codes R02-3 and R02-6) and the cut rose cultivar Rosa ‘Tan09283’ (Registration name ‘Beluga’). Laser wounding treatments were based on the assisted removal of tissue layers located in the bark. The positioning of wounding was studied based on two marking directions: along the cutting base (strip pattern) and around the cutting base (ring pattern). Additionally, the effects of external supply of indole-butyric acid (IBA 1 mg L-1) on rooting were analyzed. Results showed that in order to remove specific tissue layers, the calculation of the laser energy density (J cm-2) in terms of cutting diameter was necessary. Interestingly, the application of energy densities from 2.5 J cm-2 up to approximately 8.5 J cm-2 were sufficient to expose the tissue layers of epidermis up to regions of phloem. Regarding AR formation for R. canina ‘Pfänder’, characterized by a low rooting response, an increase in the rooting percentage was registered when the laser treatment eliminated the tissue up to phloem proximities. Analysis of the nodal position showed that bud location was a preferential place for AR formation independently of wounding treatment. In case of Rosa ‘Tan09283’, laser treatments did not reduce its high rooting capacity, but an apparent reduction in rooting quality due to an investment in tissue healing was observed when wounding reached deeper layers such as parenchyma and sclerenchyma. Results also showed a strong AR formation directly from wounded regions in case of Rosa ‘Tan09283’ specifically when the wound was located below the axillary bud. In conclusion, wounding by assisted-elimination of layers by laser can induce positive effects on AR formation of single-node stem cuttings of the rose if energy applied is able to expose phloem proximities, a longitudinal orientation, and relative position to the axillary bud are considered.

description: Controlling the type and density of charge carriers by doping is the key step for developing graphene electronics. However, direct doping of graphene is rather a challenge. Based on first-principles calculations, a concept of overcoming doping difficulty in graphene via substrate is reported.We find that doping could be strongly enhanced in epitaxial graphene grown on silicon carbide substrate. Compared to free-standing graphene, the formation energies of the dopants can decrease by as much as 8 eV. The type and density of the charge carriers of epitaxial graphene layer can be effectively manipulated by suitable dopants and surface passivation. More importantly, contrasting to the direct doping of graphene, the charge carriers in epitaxial graphene layer are weakly scattered by dopants due to the spatial separation between dopants and the conducting channel. Finally, we show that a similar idea can also be used to control magnetic properties, for example, induce a half-metallic state in the epitaxial graphene without magnetic impurity doping.

description: Recent developments in the area of resonant dielectric nanostructures have created attractive opportunities for concentrating and manipulating light at the nanoscale and the establishment of the new exciting field of all-dielectric nanophotonics. Transition metal dichalcogenides (TMDCs) with nanopatterned surfaces are especially promising for these tasks. Still, the fabrication of these structures requires sophisticated lithographic processes, drastically complicating application prospects. To bridge this gap and broaden the application scope of TMDC nanomaterials, we report here femtosecond laser-ablative fabrication of water-dispersed spherical TMDC (MoS2 and WS2) nanoparticles (NPs) of variable size (5 to 250 nm). Such NPs demonstrate exciting optical and electronic properties inherited from TMDC crystals, due to preserved crystalline structure, which offers a unique combination of pronounced excitonic response and high refractive index value, making possible a strong concentration of electromagnetic field in the NPs. Furthermore, such NPs offer additional tunability due to hybridization between the Mie and excitonic resonances. Such properties bring to life a number of nontrivial effects, including enhanced photoabsorption and photothermal conversion. As an illustration, we demonstrate that the NPs exhibit a very strong photothermal response, much exceeding that of conventional dielectric nanoresonators based on Si. Being in a mobile colloidal state and exhibiting superior optical properties compared to other dielectric resonant structures, the synthesized TMDC NPs offer opportunities for the development of next-generation nanophotonic and nanotheranostic platforms, including photothermal therapy and multimodal bioimaging.

description: Antimicrobial resistance is one of the greatest threats to human health. Gram-positive methicillin resistant Staphylococcus aureus (MRSA), in both its planktonic and biofilm form, is of particular concern. Herein we identify the hydrogelation properties for a series of intrinsically fluorescent, structurally related supramolecular self-associating amphiphiles and determine their efficacy against both planktonic and biofilm forms of MRSA. To further explore the potential translation of this hydrogel technology for real-world applications, the toxicity of the amphiphiles was determined against the eukaryotic multicellular model organism, Caenorhabditis elegans. Due to the intrinsic fluorescent nature of these supramolecular amphiphiles, material characterisation of their molecular self-associating properties included; comparative optical density plate reader assays, rheometry and widefield fluorescence microscopy. This enabled determination of amphiphile structure and hydrogel sol dependence on resultant fibre formation.

description: The Cornell University Energy Recovery Linac (ERL) photoinjector has recently demonstrated operation at 20 mA for approximately 8 hours, utilizing a multialkali photocathode deposited on a Si substrate. We describe the recipe for photocathode deposition, and will detail the parameters of the run. Post-run analysis of the photocathode indicates the presence of significant damage to the substrate, perhaps due to ion back-bombardment from the residual beamline gas. While the exact cause of the substrate damage remains unknown, we describe multiple surface characterization techniques (X-ray fluorescence spectroscopy, X-ray diffraction, atomic force and scanning electron microscopy) used to study the interesting morphological and crystallographic features of the photocathode surface after its use for high current beam production. Finally, we present a simple model of crystal damage due to ion back-bombardment, which agrees qualitatively with the distribution of damage on the substrate surface.

description: We derive a stochastic process that describes the kinetics of a one-dimensional Bose gas in a regime where three body collisions are important. In this situation the system becomes non integrable offering the possibility to investigate dissipative phenomena more simply compared to higher dimensional gases. Unlike the quantum Boltzmann equation describing the average momentum distribution, the stochastic approach allows a description of higher-order correlation functions in a canonical ensemble. As will be shown, this ensemble differs drastically from the grand canonical one. We illustrate the use of this method by determining the time evolution of the momentum mode particle number distribution and the static structure factor during the evaporative cooling process.

description: Although virtual reality, video entertainment, and computer games are dependent on the three-dimensional reproduction of sound (including front, rear, and height channels), it remains unclear whether 3D-audio formats actually intensify the emotional listening experience. There is currently no valid inventory for the objective measurement of immersive listening experiences resulting from audio playback formats with increasing degrees of immersion (from mono to stereo, 5.1, and 3D). The development of the Immersive Music Experience Inventory (IMEI) could close this gap. An initial item list (N = 25) was derived from studies in virtual reality and spatial audio, supplemented by researcher-developed items and items extracted from historical descriptions. Psychometric evaluation was conducted by an online study (N = 222 valid cases). The N = 222 Participants (female = 112, mean age = 38.6) were recruited via mailing lists (n = 34) and via a panel provider (n = 188). Based on controlled headphone playback, participants listened to four songs/pieces, each in the three formats of mono, stereo, and binaural 3D audio. The latent construct “immersive listening experience” was determined by probabilistic test theory (item response theory, IRT) and by means of the many-facet Rasch measurement (MFRM). As a result, the specified MFRM model showed good model fit (62.69% of explained variance). The final one-dimensional inventory consists of 10 items and will be made available in English and German.

description: We propose a scheme for detecting and differentiating deeply subwavelength particles based on their spatial features. Our approach combines scattering from an ultrasonically modulated nanopatterend grating with heterodyne techniques to enable far-field detection of high spatial frequency Fourier components. Our system is sensitive to spatial features commensurate in size to the patterning scale of the grating. We solve the scattering problem in Born approximation and illustrate the dependence of the signal amplitude at modulation frequency on grating period, which allows to differentiate between model nanoparticles of size $λ/20$.

Heme utilization and storage by Cryptococcus neoformans.
Creators: name: Scofield, Melanie
Publisher: name: University of British Columbia
Year: 2010

description: The opportunistic fungal pathogen Cryptococcus neoformans has been previously shown to use heme as a sole iron source, but the mechanisms for heme utilization are unknown. The goal of this study was to begin a genetic analysis of heme utilization in C. neoformans by deletion of candidate genes and phenotypic characterization. The first hypothesis was that a putative heme oxygenase protein, Hmx1, was responsible for degrading heme to release iron. However, an hmx1 deletion strain was capable of growth on heme, indicating that the gene is not required for heme utilization. The expression pattern of HMX1 showed down-regulation in the presence of heme and hemoglobin indicating that HMX1 likely plays a regulatory role within the cell. Because loss of the heme-related gene HMX1 did not reveal any phenotypes related to heme as an iron source, the role of the vacuolar protein Vps41 in iron and heme utilization was also examined. The work on Vps41 was designed to test a second more general hypothesis that the vacuole is involved in heme or iron storage and utilization. It was found that vps41 mutants had heme and iron growth defects, as well as increased sensitivity to excess levels of both heme and inorganic iron. Analysis of the wild-type strain grown with heme led to the surprising discovery of dark intracellular aggregates that were visible with light microscopy. These aggregates were reminiscent of the crystallized heme (hemozoin) found in malaria parasites. In contrast, the cells of vps41 mutants became filled with diffuse heme throughout the cell, indicating that an intact vacuole was required for aggregate formation. The inability of the mutant to sequester heme in the aggregates may contribute to the observed sensitivity of the strain to heme toxicity. Overall, these results provide new insights into heme utilization and storage in C. neoformans.

description: The first High Kinetic Energy-Ion Mobility Spectrometry-Mass Spectrometry (HiKE-IMS-MS) studies involving six volatiles (acetone, acetonitrile, methanol, ethanol, 2-propanol, and 1-butanol) and their fully deuterated analogues are reported. The goal is to further our understanding of the ion–molecule chemistry occurring in the HiKE-IMS. This is needed for its full analytical potential to be reached. Product ions are identified as a function of the reduced electric field (30–115 Td) and the influence of sample air humidity in the reaction region on deuterium/hydrogen (D/H) exchange reactions is discussed. Reagent ions include H3O+(H2O)m (n = 0, 1, 2 or 3), NO+(H2O)n (m = 0 or 1) and O2+·. Reactions with H3O+(H2O)m lead to protonated monomers (through either proton transfer or ligand switching). Reactions with NO+ involve association with acetone and acetonitrile, hydride anion abstraction from ethanol, 2-propanol, and 1-butanol, and hydroxide abstraction from 2-propanol and 1-butanol. With the exception of acetonitrile, O2+· predominantly reacts with the volatiles via dissociative charge transfer. A number of sequential secondary ion-volatile processes occur leading to the formation of dimer and trimer-containing ion species, whose intensities depend on a volatile’s concentration and the reduced electric field in the reaction region. Deuterium/hydrogen (D/H) exchange does not occur for product ions from acetone-d6 and acetonitrile-d3, owing to their inert methyl functional groups. For the deuterated alcohols, rapid D/H-exchange reaction at the hydroxy group is observed, the amount of which increased with the increasing humidity of the sample air and/or lowering of the reduced electric field.

description: We report a strain-controlled tuning of magnetism in transition-metal-atom-decorated graphene. Our first-principles calculations demonstrate that strain can lead to a sudden change in the magnetic configuration of a transition metal (TM) adatom and the local atomic structure in the sur- rounding graphene layer, which have a dramatic effect on the effective exchange coupling between neighboring TM atoms. A strong spin-dependent hybridization between TM d and graphene 1/4 orbital states, derived from the orbital selection rule of the local lattice symmetry, is responsible for the determination of the local electronic and magnetic structure. Our results indicate that the strain can be an effective way to control the magnetism of atomic-scale nanostructures, where the reliable control of their magnetic states is a key step for the future spintronic applications.

description: In this paper we study an abelian version of the notion of return word. Our main result is a new characterization of Sturmian words via abelian returns. Namely, we prove that a word is Sturmian if and only if each of its factors has two or three abelian returns. In addition, we describe the structure of abelian returns in Sturmian words, and discuss connections between abelian returns and periodicity.

description: We present a general approach for coupling a specific mode in a planar photonic crystal (PC) waveguide to a desired free-space mode. We apply this approach to a W1 PC waveguide by introducing small index perturbations to selectively couple a particular transverse mode to an approximately Gaussian, slowly diverging free space mode. This "perturbative photonic crystal waveguide coupler" (PPCWC) enables efficient interconversion between selectable propagating photonic crystal and free space modes with minimal design perturbations.

Philosophical Expertise
Creators: name: Kilov, Daniel
Publisher: name: The Australian National University

description: This thesis is about expertise and, in particular, philosophical expertise. It is a response to a question that kept me up at night in the early stages of my PhD program: what kinds of expertise, if any, am I developing here? As the saying goes, all research is me-search. The thesis is a play in three parts. In Part I, I argue that expertise is brittle, and that the brittleness of expertise should make us suspicious of a common self-conception of philosophers as possessing a set of domain-general thinking skills (e.g., logical, and conceptual analysis) that can be fruitfully applied to any subject. Part II of my thesis details my efforts to test philosophical expertise directly, via the use of empirical methods. The first study aimed to determine whether philosopher's exhibit any of cognitive hallmarks common to experts in other disciplines (e.g., poor memory for surface level details, difficulties predicting novice behaviour) with respect to their judgements about philosophical cases. We found no evidence of philosophical expertise among professional philosophers. Our second study explored whether philosophical training improved performance with respect to certain modal illusions. We found that philosophical training bore no relationship to expertise with respect to modal judgements, but that mathematical training did. In Part III, I argue that a growing body of empirical research, including the studies described in the preceding paragraph, suggest that armchair methods alone are inadequate. If we wish to make progress in philosophy, we must augment our armchairs and embrace what I call 'broad-church experimental philosophy'.
