description: In Little Higgs models a collective symmetry prevents the Higgs from acquiring a quadratically divergent mass at one loop. This collective symmetry is broken by weakly gauged interactions. Terms, like Yukawa couplings, that display collective symmetry in the bare Lagrangian are generically renormalized into a sum of terms that do not respect the collective symmetry except possibly at one renormalization point where the couplings are related so that the symmetry is restored. We study here the one loop renormalization of a prototypical example, the Littlest Higgs Model. Some features of the renormalization of this model are novel, unfamiliar form similar chiral Lagrangian studies.

description: A double-loop four-Josephson-junction (4-JJ) flux qubit is a tunable qubit wherein the potential profile can be varied in situ via two applied magnetic fluxes. This provides a high level of control over state transitions. Here, we report the results of spectroscopic measurements on this system. We observed microwave resonances associated with the first and second excited states. A branch of resonances that is most likely attributable to the third excited state was also observed. The excitation energy spectra for these levels were in qualitative agreement with the results of simplified calculations performed using an effective Hamiltonian with two phases. The three lowest levels characterized in this study may allow novel applications, including those proposed theoretically in the past. Our analysis showed that the potential exhibited a crossover from the commonly used double-well regime to the novel single-well regime. This indicates the possibility of manipulation and readout of a 3-JJ (and 4-JJ) qubit in the single-well regime using a simple technique.

description: In anomaly-mediated supersymmetry breaking (AMSB) models, superpartner masses are proportional to couplings squared. Their hidden sectors therefore naturally contain WIMPless dark matter, particles whose thermal relic abundance is guaranteed to be of the correct size, even though they are not weakly-interacting massive particles (WIMPs). We study viable dark matter candidates in WIMPless AMSB models with non-Abelian hidden sectors and highlight unusual possibilities that emerge in even the simplest models. In one example with a pure SU(N) hidden sector, stable hidden gluinos freeze out with the correct relic density, but have an extremely low, but natural, confinement scale, providing a framework for self-interacting dark matter. In another simple scenario, hidden gluinos freeze out and decay to visible Winos with the correct relic density, and hidden glueballs may either be stable, providing a natural framework for mixed cold-hot dark matter, or may decay, yielding astrophysical signals. Last, we present a model with light hidden pions that may be tested with improved constraints on the number of non-relativistic degrees of freedom. All of these scenarios are defined by a small number of parameters, are consistent with gauge coupling unification, preserve the beautiful connection between the weak scale and the observed dark matter relic density, and are natural, with relatively light visible superpartners. We conclude with comments on interesting future directions.

description: An approach for high-throughput analysis of bulk and contact conductance of polymer layers is described and evaluated. The approach, based on s24-technique (simultaneous two- and four-point conductance measurements), was realized as a high-throughput method and applied for investigation of conductive polymers on an array of interdigital platinum electrodes. Several examples demonstrate distinctive influence of combinatorially varied conditions of polymer synthesis (polymerization charge, content of copolymers) as well as chemical treatment of the synthesized polymers in bulk and contact resistance of metal/polymer/metal systems. The developed high-throughput s24-technique can be widely applied to material research for investigation of bulk and contact electrical properties.

description: We prove that the geodesic equations of all Sobolev metrics of fractional order one and higher on spaces of diffeomorphisms and, more generally, immersions are locally well posed. This result builds on the recently established real analytic dependence of fractional Laplacians on the underlying Riemannian metric. It extends several previous results and applies to a wide range of variational partial differential equations, including the well-known Euler-Arnold equations on diffeomorphism groups as well as the geodesic equations on spaces of manifold-valued curves and surfaces.

description: We study the $W/Z$ pair production via two-photon exchange at the LHC and give the sensitivities on trilinear and quartic gauge anomalous couplings between photons and $W/Z$ bosons for an integrated luminosity of 30 and 200 fb$^{-1}$. For simplicity and to obtain lower backgrounds, only the leptonic decays of the electroweak bosons are considered. The intact protons in the final states are detected in the ATLAS Forward Proton detectors. The high energy and luminosity of the LHC and the forward detectors allow to probe beyond standard model physics and to test the higgsless and extra dimension models in an unprecedent way.

description: We describe two new fluorescence resonance energy transfer (FRET) compatible labels, their covalent linkage to oligonucleotides, and their use as donor and acceptor, respectively, in FRET hybridization studies. The dyes belong to the cyanine dyes, and water solubility is imparted by a phosphonate which represents a new solubilizing group in DNA labels. They were linked to amino-modified synthetic oligonucleotides via oxysuccinimide (OSI) esters. The studies performed include binding assays, determinations of molecular distances, homogeneous competitive assays, and limits of detection, which are in the order of 5 pmol/L for a 15-mer.

Subjects: subject: 540 Chemie

description: Optical chemical sensors are capable of continuously recording a chemical species and thus have found (and will find) numerous applications in areas such as the chemical industry, in biotechnology and medicine. Among the many optical methods are employed for sensing purposes, fluorescence has attracted particular attention because it is sensitive, has numerous parameters that can serve as an analytical information and knows effects unknown to other spectroscopies. The implementation of spectroscopic schemes into a useful sensing scheme has been hampered though, by the lack of appropriate materials including polymers and particles, indicator probes, molecular receptors, carriers, catalysts and fluorescent semiconductor materials. This article will address the progress made in the past years and some of the futures aspects and challenges.

description: Recently, video-based action recognition methods using convolutional neural networks (CNNs) achieve remarkable recognition performance. However, there is still lack of understanding about the generalization mechanism of action recognition models. In this paper, we suggest that action recognition models rely on the motion information less than expected, and thus they are robust to randomization of frame orders. Furthermore, we find that motion monotonicity remaining after randomization also contributes to such robustness. Based on this observation, we develop a novel defense method using temporal shuffling of input videos against adversarial attacks for action recognition models. Another observation enabling our defense method is that adversarial perturbations on videos are sensitive to temporal destruction. To the best of our knowledge, this is the first attempt to design a defense method without additional training for 3D CNN-based video action recognition models.

The analysis by GC-MS and GC-FID techniques showed the presence of 38 compounds in J. oxycedrus oil where the major constituents were manoyl oxide (23.5%), pentadecan-2-enone 6Z (12.6%), abietatriene (8.0%), abieta-8,11,13-triene-7-one (6.5%), cubebol (4.6%), epi-torilenol (3.8%) and α-cadinol (2.6%), while, a total of 65 compounds were showed in C. sempervirens oil where the major constituents were α-pinene (68.0%), epi-cedrol (6.1%), α-terpenyl acetate (3.5%) and germacrene D (2.5%). It is the first time that the compounds pentadecan-2-enone 6Z, abieta-8,11,13-trien-7-one, cubebol and epi-torilenol have been identified in our J. oxycedrus and epi-cedrol in C. sempervirens essential oils with high contents, as we noticed the absence of α-pinene in our J. oxycedrus essential oil.

description: In this paper we study repulsion of a Néel-type skyrmion in a chiral ferromagnetic film from a superconducting Pearl vortex due to the stray fields. Taking into account an effect of the vortex magnetic field on the skyrmion non-perturbatively, we find that the repulsion between them is suppressed with increase of the dimensionless strength of the vortex magnetic field. This manifests itself in complicated evolution of the free energy with increase of the vortex magnetic field and reduction of the equilibrium distance between the centers of Néel-type skyrmion and Pearl vortex.

description: Purpose: Insights from linguistic variation research illustrate a linguistically diverse population, in which even speakers who can be classified as speaking a “mainstream” variety have grammatical knowledge of vernacular or “nonmainstream” features. However, there is a gap in our knowledge regarding how vernacular features are comprehended in people with aphasia (PWA). This article presents the results of a pilot study exploring how PWA respond to linguistic stimuli that include the vernacular feature, negative concord (NC), often referred to by the more colloquial term double negative (e.g., I didn’t do nothing, equivalent to I didn’t do anything).Method: Twelve PWA in the chronic stage of recovery each rated the naturalness and felicity of 48 critical sentences and 64 fillers, all of which contained two clauses, the second clause describing a consequence of the first. Ratings were analyzed using ordinal regression.Results: PWA rated NC sentences as unacceptable, but felicitous—a pattern similar to that shown by neurologically intact adults in a previous study. Conclusions: These results suggest that PWA are sensitive to both social and linguistic information at levels similar to neurologically intact speakers. These results have implications for the integration of vernacular features into future research, assessment, and treatment protocols for PWA.

Adaptive variation of mitochondrial function in response to oxygen variability in intertidal sculpins (Cottidae, Actinopterygii)
Creators: name: Lau, Gigi Yik Chee
Publisher: name: University of British Columbia
Year: 2019

description: Variation in environmental oxygen (O₂) poses a significant physiological challenge to animals, not only because of the impact on aerobic metabolism, but also because it can lead to generation of potentially harmful reactive oxygen species (ROS). In this thesis, I aimed to investigate the interplay between two aspects of O2 use at the mitochondria, aerobic respiration and ROS metabolism, using species of intertidal sculpins (Cottidae, Actinopterygii) which are distributed along the marine intertidal zone, exposed to varying O2 conditions and vary in their tolerance to low O₂ (hypoxia). I first hypothesized that there would be a relationship between whole animal hypoxia tolerance and mitochondrial and cytochrome c oxidase (COX) O₂-binding affinity, whereby hypoxia tolerant sculpins would have higher mitochondrial and COX O₂-binding affinity than less hypoxia tolerant sculpins. This hypothesis was supported with functional analysis. In silico modelling of the COX catalytic core revealed that the variation in O₂ binding was related to interspecific differences in the interaction between COX3 and membrane phospholipid, cardiolipin, which could impact O₂ diffusion to its binding site. I then investigated whether intact mitochondria from hypoxia tolerant sculpins were able to use O₂ more efficiently such that phosphorylation efficiency was improved and ROS generation was reduced compared to mitochondria from less hypoxia tolerant sculpins. Although there were relationships between hypoxia tolerance and complex I and II dependencies, there were no interspecies differences in phosphorylation or mitochondrial coupling that would indicate differences in aerobic metabolism. Moreover, mitochondria from hypoxia tolerant sculpins generated more ROS under resting conditions and were more perturbed by in vitro redox and anoxia-recovery challenges. Finally, I confirmed consistent responses of mitochondria to in vivo responses with a whole animal study comparing ROS metabolism (redox status, mitochondrial H₂O₂, oxidative damage and scavenging capacity) between two sculpin species with different hypoxia tolerance to hypoxia, hyperoxia, with normoxia-recovery exposures. Taken together, my thesis demonstrates that hypoxia tolerance is associated with improved O₂ binding at the mitochondria and COX. Further, hypoxia tolerance in sculpins is associated with higher ROS generation compared to less tolerant species, suggesting a potentially important role of ROS in mediating hypoxia tolerance.

description: We investigate the consistency relation relating the squeezed limit of the bispectrum to the scalar spectral index in single field models of inflation. We give a simple integral formula for the bispectrum in the squeezed limit in terms of the free mode mode functions of the primordial curvature perturbation, in any Lorentz invariant single field model of inflation and without resorting to any approximation, generalizing a recent result obtained by Ganc and Komatsu in the case of canonical kinetic terms. We use our result to verify the consistency relation in an exactly solvable class of models with a non-trivial speed of sound. We then verify the consistency relation at the first non-trivial order in the slow-varying approximation in general single field inflation (a known result) and at second order in this approximation in canonical single field inflation.

description: G-quadruplex DNA stabilization mediated by small molecules is an attractive approach to modulate the transcription of guanine-rich sequences and contrast unregulated cell proliferation. Natural alkaloids have been reported to target this macromolecular arrangement, and such mechanism may be among these underlying the antiproliferative effect of some flavonoids. The binding affinity for G-quadruplex and double stranded DNA of 4 isoflavones from Maclura pomifera, namely osajin, pomiferin, scandenone and auriculasin, was evaluated using electrospray mass spectrometry (ESI-MS). The experiments pointed out that osajin and scandenone preferentially bind G-quadruplex. Moreover, since G-quadruplex stabilization is a crucial aim for triggering biological effects such as gene expression, collision-induced dissociation (CID) assays were performed to study the relative gas-phase kinetic stability of the DNA/ligand complexes. Osajin was identified as the best G-quadruplex stabilizer of the set, and in silico docking studies indicate that stacking is the preferred interaction motif of this natural compound.

description: Il Banco di Santa Croce è uno dei siti d’immersione più frequentati dai subacquei tecnici e ricreativi che frequentano il versante tirrenico centro-meridionale della nostra Penisola. La morfologia articolata del paesaggio sottomarino, infatti, rende il sito adatto a diverse tipologie di immersione (Fig.1). Questo sito si trova in uno dei tratti costieri del territorio italiano storicamente più studiati: il Golfo di Napoli. Questo luogo è stato definito come un esempio di “paradosso biologico” essendo localizzato in un’area costiera soggetta a consistenti fonti d’impatto antropico. Ci troviamo infatti all’ombra dell’imponente edificio vulcanico del Vesuvio ovvero una delle zone più densamente abitate della regione Campania, a pochi chilometri dalla foce del Fiume Sarno considerato tra i corsi d’acqua più impattati d’Europa e a poche miglia da alcune mete turistiche molto frequentate specialmente nel periodo estivo come la Penisola Sorrentina e la Costiera Amalfitana.

description: Motivated by the recent work about the Extended Uncertainty Principle (EUP) black holes \cite{Mureika:2018gxl}, we present in this study its extension called the Generalized Extended Uncertainty Principle (GEUP) black holes. In particular, we investigated the GEUP effects on astrophysical and micro-black holes. First, we derive the expression for the shadow radius to investigate its behavior as perceived by a static observer located near and far from the black hole. Constraints to the large fundamental length scale $L*$ up to $2σ$ level were also found using the EHT data: for Sgr. A*, $L* = 5.716\text{x}10^{10}$ m, while for M87*, $L* = 3.264\text{x}10^{13}$ m. Under the GEUP effect, the value of the shadow radius behaves the same way as the Schwarzschild case due to a static observer, and the effect only emerges if the mass of the black hole $M$ is around the order of magnitude of $L_*$ (or $l_\text{Pl}$). In addition, the GEUP effect increases the shadow radius for astrophysical black holes, but the reverse happens for micro-black holes. We also explored GEUP effects to the weak and strong deflection angles as an alternative analysis. For both realms, a time-like particle gives a higher value for the weak deflection angle. Similar to the shadow, the deviation is seen when the values of $L_*$ and $M$ are close. The strong deflection angle gives more sensitivity to GEUP deviation at smaller masses in the astrophysical scenario. However, the weak deflection angle is a better probe in the micro world.

description: We present an open-system quantum-mechanical 3D real-space study of the conduction band structure and conductive properties of two semiconductor systems, interesting for their beyond-Moore and quantum computing applications: phosphorus $δ$-layers in silicon and the corresponding $δ$-layer tunnel junctions. In order to evaluate size quantization effects on the conductivity, we consider two principal cases: nanoscale finite-width structures, used in transistors, and infinitely-wide structures, electrical properties of which are typically known experimentally. For devices widths $W<10$~nm, quantization effects are strong and it is shown that the number of propagating modes determines not only the conductivity, but the distinctive spatial distribution of the current-carrying electron states. For $W>10$~nm, the quantization effects practically vanish and the conductivity tends to the infinitely-wide device values. For tunnel junctions, two distinct conductivity regimes are predicted due to the strong conduction band quantization.

description: We study the fidelity decay of the $k$-body embedded ensembles of random matrices for bosons distributed over two single-particle states. Fidelity is defined in terms of a reference Hamiltonian, which is a purely diagonal matrix consisting of a fixed one-body term and includes the diagonal of the perturbing $k$-body embedded ensemble matrix, and the perturbed Hamiltonian which includes the residual off-diagonal elements of the $k$-body interaction. This choice mimics the typical mean-field basis used in many calculations. We study separately the cases $k=2$ and $3$. We compute the ensemble-averaged fidelity decay as well as the fidelity of typical members with respect to an initial random state. Average fidelity displays a revival at the Heisenberg time, $t=t_H=1$, and a freeze in the fidelity decay, during which periodic revivals of period $t_H$ are observed. We obtain the relevant scaling properties with respect to the number of bosons and the strength of the perturbation. For certain members of the ensemble, we find that the period of the revivals during the freeze of fidelity occurs at fractional times of $t_H$. These fractional periodic revivals are related to the dominance of specific $k$-body terms in the perturbation.

description: In the last decade, extraction of unconventional oil and gas (UOG) has rapidly increased in Canada. One of the major concerns related to UOG extraction is the risk of accidental releases during wastewater management. UOG extraction uses technologies of horizontal drilling and hydraulic fracturing. Flowback and produced water are generated as wastewater and may contain high concentrations of salts, metals, oil, grease, and organic compounds. Flowback water is stored on site before being transported for treatment, reuse or disposal. It is stored in containment pond, above ground walled storage systems (AWSS) or storage tanks. A comprehensive risk assessment has been carried out for the accidental release of flowback water during the storage. Two components of risk namely probability of failure and consequence assessment on the ecology have been examined using the frameworks of Backward Integrated Analysis (BIA) and Ecological Risk Assessment (ERA), respectively. In BIA, failure modes were identified for an uncontrolled release of flowback water due to AWSS failure by developing a fault tree. The probability of failure of the system was calculated and its failure modes were ranked by assigning risk priority number (RPN). To assess the consequence of the accidental release, the toxicity and exposure of the flowback water components to the aquatic ecology were examined through ERA. Toxicity of each constituent of flowback water was assessed by developing species sensitivity distribution curves. An exposure model using dilution factor and adsorption coefficient of the flowback water constituents is proposed and risk quotient was used to characterize ecological risk. To demonstrate the methodology, a case study in Montney unconventional play in Northern BC was carried out. The risk to the aquatic ecology was found to be very low, however, scenario analysis and uncertainty analysis prove that the risk cannot be completely overlooked. A review of the regulations for storage systems was carried out and they were assessed in light of the results of the study. Enforcing regulations pertaining to the quality of water stored, citing of the storage system with respect to the water body and making secondary system mandatory were realized to be the most beneficial.

description: We study the scaling properties in deep inelastic scattering using the most recent combined structure function data $F_2$ from the H1 and ZEUS collaborations. We also perform a direct fit to the $F_2$ data inspired by the scaling properties. Our analysis favours the QCD saturation mechanism from the Balitski Kovchegiv equation wuth running coupling.

description: Il Banco di Santa Croce è uno dei siti d’immersione più frequentati dai subacquei tecnici e ricreativi che frequentano il versante tirrenico centro-meridionale della nostra Penisola. La morfologia articolata del paesaggio sottomarino, infatti, rende il sito adatto a diverse tipologie di immersione (Fig.1). Questo sito si trova in uno dei tratti costieri del territorio italiano storicamente più studiati: il Golfo di Napoli. Questo luogo è stato definito come un esempio di “paradosso biologico” essendo localizzato in un’area costiera soggetta a consistenti fonti d’impatto antropico. Ci troviamo infatti all’ombra dell’imponente edificio vulcanico del Vesuvio ovvero una delle zone più densamente abitate della regione Campania, a pochi chilometri dalla foce del Fiume Sarno considerato tra i corsi d’acqua più impattati d’Europa e a poche miglia da alcune mete turistiche molto frequentate specialmente nel periodo estivo come la Penisola Sorrentina e la Costiera Amalfitana.

description: We present an open-system quantum-mechanical real-space study of the conductive properties and size quantization in phosphorus $δ$-layers systems, interesting for their beyond-Moore and quantum computing applications. Recently it has been demonstrated that an open-system quantum mechanical treatment provides a much more accurate match to ARPES measurements in highly-conductive, highly-confined systems than the traditional approaches (i.e. periodic or Dirichlet boundary conditions) and, furthermore, it allows accurate predictions of conductive properties of such systems from the first principles. Here we reveal that quantization effects are strong for device widths $W<10$~nm, and we show, for the first time, that the number of propagating modes determines not only the conductivity, but the distinctive spatial distribution of the current-carrying electron states. For $W>10$~nm, the quantization effects practically vanish and the conductivity tends to the infinitely-wide device's values.

description: Purpose: This study sought to determine if children with childhood apraxia of speech (CAS) plus another major diagnosis (CAS+) are equivalent in communication and motor profiles to those with a primary diagnosis of CAS and no indication or report of any other diagnosis (CAS-Primary).Method: This retrospective case–control study included a chart review of 143 children who were suspected of having CAS at Children’s Hospital-Wisconsin between 1998 and 2004. Participants were between 30 and 127 months old and included 107 males. Participants were assigned to the suspected CAS-Primary group (n = 114) if they had characteristics of CAS but no other major diagnosis (e.g., galactosemia) and to the CAS+ group (n = 29) if a comorbid diagnosis was present. Groups were compared across demographic, communication, and motor characteristics.Results: Children with CAS+ evidenced more severe motor profiles than those with CAS-Primary, χ2 = (1, n = 122) = 4.952, p = .026, and a small-to-medium effect size (Ф = .201). On average, communication profiles also tended to be more severe among those with CAS+ wherein receptive language was poorer and phonemic inventories were smaller than those with CAS-Primary.Conclusions: These retrospective data suggest that comorbid diagnosis may play an important role in communication and motor development in children with suspected CAS. These exploratory findings should motivate future prospective studies that consider the role of concomitant diagnoses in symptom profile and response to treatment in children with CAS.

description: The utilisation of a hybrid lightweight design based on fibre-reinforced plastics (FRP) represents a promising methodology for addressing the increasing demands placed on components. Nevertheless, this field is confronted with significant challenges, particularly regarding the economic production of the materials and the development of efficient joining techniques. This lecture is devoted to an investigation of innovative hybrid designs comprising fibre-plastic composites in conjunction with metallic components. The hybrid components are manufactured using the pultrusion process, which enables efficient production. A salient feature of the hybrid components developed at the Fraunhofer IWU is the design of the metal component as a protruding joining tongue. This is intended to facilitate the utilisation of welding processes. The primary objective is to render conventional welding techniques, such as arc welding, applicable, thereby markedly facilitating their deployment in novel applications. To guarantee the functionality and durability of the hybrid composite, it is essential to ensure a high level of adhesion between the FRP and metal components. A novel hybrid technology, based on special textile and welding techniques, was used for this purpose. Furthermore, an innovative die concept was developed for the manufacture of hybrid components using the pultrusion process. In essence, this is a self-sealing die concept with adjustable clamping forces, which serve to guarantee a bare metal profile that protrudes from the FRP base structure. This is intended to ensure that subsequent joining can be carried out without the necessity for time-consuming reworking (e.g. no uncovering of the metal profile). The functionality of the die system was validated for a range of materials and process parameters. Tensile tests were conducted to assess the bond strength of the developed hybrid components, while welding tests were performed to evaluate the weldability. Additionally, tensile tests were performed on welded samples to validate the residual strength.
