description: In this paper we couple noncommutative (NC) vielbein gravity to scalar fields. Noncommutativity is encoded in a star product between forms, given by an abelian twist (a twist with commuting vector fields). A geometric generalization of the Seiberg-Witten map for abelian twists yields an extended theory of gravity coupled to scalars, where all fields are ordinary (commutative) fields. The vectors defining the twist can be related to the scalar fields and their derivatives, and hence acquire dynamics. Higher derivative corrections to the classical Einstein-Hilbert and Klein-Gordon actions are organized in successive powers of the noncommutativity parameter θ^{AB}.

Stability of topological defects in chiral superconductors: London theory

Subjects: subject: Superconductivity (cond-mat.supr-con)

subject: FOS: Physical sciences

description: This paper examines thermodynamic stability of chiral domain walls and vortices - topological defects which can exist in chiral superconductors. Using London theory it is demonstrated that at sufficiently small applied and chiral fields the existence of domain walls and vortices in the sample is not favored and the sample's configuration is a single domain. The particular chirality of the single-domain configuration is neither favored nor disfavored by the applied field. Increasing the field leads to an entry of a domain wall loop or a vortex into the sample. Formation of a straight domain wall is never preferred in equilibrium. Values of the entry (critical) fields for both types of defects, as well as the equilibrium size of the domain wall loop, are calculated. We also consider a mesoscopic chiral sample and calculate its zero-field magnetization, susceptibility and a change in the magnetic moment due to a vortex or a domain wall entry. We show that in a case of a soft domain wall whose energetics is dominated by the chiral current (and not by the surface tension) its behavior in mesoscopic samples is substantially different from that in the bulk case and can be used for a controllable transfer of edge excitations. The applicability of these results to Sr2RuO4 - a tentative chiral superconductor - is discussed.

description: Much effort has gone into understanding the modular nature of complex networks. Communities, also known as clusters or modules, are typically considered to be densely interconnected groups of nodes that are only sparsely connected to other groups in the network. Discovering high quality communities is a difficult and important problem in a number of areas. The most popular approach is the objective function known as modularity, used both to discover communities and to measure their strength. To understand the modular structure of networks it is then crucial to know how such functions evaluate different topologies, what features they account for, and what implicit assumptions they may make. We show that trees and treelike networks can have unexpectedly and often arbitrarily high values of modularity. This is surprising since trees are maximally sparse connected graphs and are not typically considered to possess modular structure, yet the nonlocal null model used by modularity assigns low probabilities, and thus high significance, to the densities of these sparse tree communities. We further study the practical performance of popular methods on model trees and on a genealogical data set and find that the discovered communities also have very high modularity, often approaching its maximum value. Statistical tests reveal the communities in trees to be significant, in contrast with known results for partitions of sparse, random graphs.

description: We review known factorization results in quaternion matrices. Specifically, we derive the Jordan canonical form, polar decomposition, singular value decomposition, the QR factorization. We prove there is a Schur factorization for commuting matrices, and from this derive the spectral theorem. We do not consider algorithms, but do point to some of the numerical literature. Rather than work directly with matrices of quaternions, we work with complex matrices with a specific symmetry based on the dual operation. We discuss related results regarding complex matrices that are self-dual or symmetric, but perhaps not Hermitian.

A chemical genetics strategy exposes novel modulators of chondrogenesis that act by blocking a potassium channel, Kcnd2, & reveals a potential role for potassium channels in limb development
Creators: name: Graham, Erin Mackenzie
Publisher: name: University of British Columbia
Year: 2013

description: Much of the vertebrate skeleton is formed through endochondral ossification. In this process, a chondrogenic template is laid down, which is subsequently replaced by bone. The first step involves condensation of mesenchymal cells and their differentiation into chondroblasts that initiate elaboration of the chondrogenic template. At later stages, chondrocytes undergo hypertrophy, and produce a matrix for bone formation. To enhance our understanding of molecular programs regulating this process a chemical genetics approach was employed. Our strategies involved the development of screens using primary cultures of murine limb bud-derived mesenchymal (PLM) cells. Chondroblast differentiation is associated with increased SOX5, 6 and 9 activity; while hypertrophic differentiation is associated with reduced SOX5, 6 and 9 activity. Therefore, a SOX5/6/9-responsive reporter gene was used to follow expression of the chondroblast phenotype. Compound libraries representing more than 1400 compounds were screened; 28 compounds were found to increase reporter gene activity greater than 2.5 fold. In secondary screens, 7 of 28 positive compounds stimulated cartilage formation, as assessed by alcian blue staining. Two compounds identified, Butamben (butyl 4-aminobenzoate; BAB) and Phenazopyridine hydrochloride (PHCl), exhibited strong pro-chondrogenic activity and morphologically similar alcian blue staining. BAB is a member of the benzocaine family of analgesics and functions by inhibiting sodium channel activity. However, BAB has also been shown to have potassium channel-blocking activity. Specifically, BAB inhibits the activity of Kcnd2; which through transcriptional profiling was also found to be down-regulated by bone morphogenetic protein-4 (BMP4). We speculated BAB and PHCl may be able to modulate chondrogenesis by acting on potassium channels. To confirm this idea we examined molecular activities of PLM cultures treated with BAB and PHCl at two stages of chondrogenesis: 1. pre-chondrocyte to chondroblast and 2. chondrocyte to hypertrophic chondrocyte. Results confirm, BAB and PHCl increase expression of chondrogenic markers and reduce expression of hypertrophic markers. In addition patch clamp analysis revealed both BAB and PHCl are able to block, at least partially, KCND2 channel activity. We confirmed the dynamic expression pattern of Kcnd2 by qPCR and radioactive section in situ hybridization. Together, these results reveal an unanticipated and novel role for Kcnd2 in chondrogenesis.

description: Hyperacusis is reported to occur in 3.2–17.1% of the general paediatric population with higher rates in clinical populations such as autism spectrum disorders (ASD). Although hyperacusis is a relatively common form of decreased sound tolerance (DST), no valid paediatric hyperacusis measures are currently available. The purpose of the present study was to develop and validate a paediatric version of the Khalfa Hyperacusis Questionnaire (HQ) as a first step towards filling this measurement gap. A cross-sectional design was used to evaluate therapist opinions of the paediatric version (P-HQ) and to field test the P-HQ in parents of children with and without ASD. Total scores were compared between ASD and non-ASD groups. Eleven paediatric occupational and speech therapists with expertise in ASD, 64 parents of children with ASD and 37 parents of children without ASD completed online questionnaires. Psychometric analyses were conducted. A unidimensional construct was found underlying P-HQ and all items displayed sufficient theoretical relevance to hyperacusis and adequate psychometric properties. The P-HQ demonstrates good internal consistency and shows promise as a potential screening tool for identifying DST in ASD. Further research is warranted to establish normative data and validate cut-off scores.

description: N-subjettiness is a jet shape designed to identify boosted hadronic objects such as top quarks. Given N subjet axes within a jet, N-subjettiness sums the angular distances of jet constituents to their nearest subjet axis. Here, we generalize and improve on N-subjettiness by minimizing over all possible subjet directions, using a new variant of the k-means clustering algorithm. On boosted top benchmark samples from the BOOST2010 workshop, we demonstrate that a simple cut on the 3-subjettiness to 2-subjettiness ratio yields 20% (50%) tagging efficiency for a 0.23% (4.1%) fake rate, making N-subjettiness a highly effective boosted top tagger. N-subjettiness can be modified by adjusting an angular weighting exponent, and we find that the jet broadening measure is preferred for boosted top searches. We also explore multivariate techniques, and show that additional improvements are possible using a modified Fisher discriminant. Finally, we briefly mention how our minimization procedure can be extended to the entire event, allowing the event shape N-jettiness to act as a fixed N cone jet algorithm.

Quantized vortex state in hcp solid 4He

Year: 2012
Subjects: subject: Other Condensed Matter (cond-mat.other)
subject: FOS: Physical sciences

description: The quantized vortex state appearing in the recently discovered new states in hcp 4He since their discovery is discussed. Special attention is given to evidence for the vortex state as the vortex fluid (VF) state and its transition into the supersolid (SS) state. Its features are described. The historical expla- nations for the SS state in quantum solids such as solid 4He were based on the idea of Bose Einstein Condensation (BEC) of the imperfections such as va- cancies, interstitials and other possible excitations in the quantum solids which are expected because of the large zero-point motions. The SS state was proposed as a new state of matter in which real space ordering of the lattice structure of the solid coexists with the momentum space ordering of superfluidity. A new type of superconductors, since the discovery of the cuprate high Tc superconductors, HTSCs, has been shown to share a feature with the vortex state, involving the VF and vortex solid states. The high Tcs of these materials are being discussed in connection to the large fluctuations associated with some other phase transitions like the antiferromagnetic transition in addition to that of the low dimensionality. The supersolidity in the hcp solid 4He, in contrast to the new superconductors which have multiple degrees of freedom of the Cooper pairs with spin as well as angular momentum freedom, has a unique feature of possessing possibly only the momentum fluctuations and vortex ring excitations associated with the possible low dimensional fluctuations of the subsystem(s). The high onset temperature of the VF state can be understood by considering thermally excited low D quantized vortices and it may be necessary to seek low dimensional sub-systems in hcp He which are hosts for vortices.

Constraints on $Λ(t)$-cosmology with power law interacting dark sectors

Publisher: name: arXiv

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: Motivated by the cosmological constant and the coincidence problems, we consider a cosmological model where the cosmological constant $Λ_0$ is replaced by a cosmological term $Λ(t)$ which is allowed to vary in time. More specifically, we are considering that this dark energy term interacts with dark matter through the phenomenological decay law $\dotρ_Λ=-Qρ_Λ^{n}$. We have constrained the model for the range $n\in[0,10]$ using various observational data (SNeIa, GRB, CMB, BAO, OHD), emphasizing the case where $n=3/2$. This case is the only one where the late-time value for the ratio of dark energy density and matter energy density $ρ_Λ/ρ_{m}$ is constant, which could provide an interesting explanation to the coincidence problem. We obtain strong limits on the model parameters which however exclude the region where the coincidence or the cosmological constant problems are significantly ameliorated.

New Approach to Nonperturbative Quantum Mechanics with Minimal Length Uncertainty
Creators: name: Pedram, Pouria
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The existence of a minimal measurable length is a common feature of various approaches to quantum gravity such as string theory, loop quantum gravity and black-hole physics. In this scenario, all commutation relations are modified and the Heisenberg uncertainty principle is changed to the so-called Generalized (Gravitational) Uncertainty Principle (GUP). Here, we present a one-dimensional nonperturbative approach to quantum mechanics with minimal length uncertainty relation which implies X=x to all orders and P=p+(1/3)βp^3 to first order of GUP parameter β, where X and P are the generalized position and momentum operators and [x,p]=i\hbar. We show that this formalism is an equivalent representation of the seminal proposal by Kempf, Mangano, and Mann and predicts the same physics. However, this proposal reveals many significant aspects of the generalized uncertainty principle in a simple and comprehensive form and the existence of a maximal canonical momentum is manifest through this representation. The problems of the free particle and the harmonic oscillator are exactly solved in this GUP framework and the effects of GUP on the thermodynamics of these systems are also presented. Although X, P, and the Hamiltonian of the harmonic oscillator all are formally self-adjoint, the careful study of the domains of these operators shows that only the momentum operator remains self-adjoint in the presence of the minimal length uncertainty. We finally discuss the difficulties with the definition of potentials with infinitely sharp boundaries.

description: Subjective promontory stimulation is used to evaluate cochlear implant (CI) candidacy, but the test reliability is low. Electrically evoked auditory brainstem response (EABR) can verify the function of the auditory system objectively. This study’s procedure uses a trans-tympanic rounded bent-tip electrode to perform pre-operative EABR under local anaesthesia (LA-TT-EABR) using MED-EL Software and Hardware. This study aimed to determine usability and effectiveness for CI candidates. We hypothesised that LA-TT-EABR waveforms of good quality would be related to successful hearing outcomes. We assumed that the duration of hearing loss/deafness was a confounding factor to study outcomes. 19 borderline CI candidates. Positive LA-TT-EABR results were confirmed in 14 patients. LA-TT-EABR’s mean latency was 2.05 ± 0.31 ms (eII/eIII) and 4.24 ± 0.39 ms (eIV/eV). Latencies weren’t statistically different from intra-operative EABR elicited by basal CI contacts. All positive LA-TT-EABR patients benefitted from CI and speech performance improved one year after implantation. One patient with negative LA-TT-EABR was cochlear-implanted and had no hearing sensation. LA-TT-EABR is a tool in the frame of pre-operative objective testing the auditory pathway. It seems useful for clinical testing CI candidacy. Based on this study’s outcomes, LA-TT-EABR should be recommended for uncertain CI candidates.

description: Understanding interactions between orbital and valley quantum states in silicon nanodevices is crucial in assessing the prospects of spin-based qubits. We study the energy spectra of a few-electron silicon metal-oxide-semiconductor quantum dot using dynamic charge sensing and pulsed-voltage spectroscopy. The occupancy of the quantum dot is probed down to the single-electron level using a nearby single-electron transistor as a charge sensor. The energy of the first orbital excited state is found to decrease rapidly as the electron occupancy increases from N=1 to 4. By monitoring the sequential spin filling of the dot we extract a valley splitting of ~230 μeV, irrespective of electron number. This indicates that favorable conditions for qubit operation are in place in the few-electron regime.

description: In a Dirac semimetal, the conduction and valence bands contact only at discrete (Dirac) points in the Brillouin zone (BZ) and disperse linearly in all directions around these critical points. Including spin, the low energy effective theory around each critical point is a four band Dirac Hamiltonian. In two dimensions (2D), this situation is realized in graphene without spin-orbit coupling. 3D Dirac points are predicted to exist at the phase transition between a topological and a normal insulator in the presence of inversion symmetry. Here we show that 3D Dirac points can also be protected by crystallographic symmetries in particular space-groups and enumerate the criteria necessary to identify these groups. This reveals the possibility of 3D analogs to graphene. We provide a systematic approach for identifying such materials and present ab initio calculations of metastable β-cristobalite BiO_2 which exhibits Dirac points at the three symmetry related X points of the BZ.

description: The overall objective in the study was to compare self-reported hearing based on a single question (“how good would you currently rate your hearing?”) to measure hearing loss determined by audiometry in a cohort of adolescents. Prevalence of audiometrically measured hearing loss and frequencies of self-reported poor hearing as well as factors that have an impact on self-reported hearing were examined. Baseline and 5-year follow-up data of the Ohrkan study were used. Participants filled in a questionnaire and underwent audiometric measurements. Data from 979 adolescents were analysed. Participants were 54.7% female and aged between 13 and 18 years at baseline and 17–21 years at 5-yr follow-up. The single question on self-reported hearing ability achieved a sensitivity of 41.9% and a positive predictive value of 7.1% at baseline. For the 5-yr follow-up, sensitivity was 40.0%, positive predictive value was 13.9%. Factors influencing self-reported poor hearing were gender, tinnitus, “muffled” ears after exposure to loud noise (e.g. after a concert) and low-frequency hearing loss. The single question about hearing ability used in the Ohrkan study is not sufficient to replace audiometry to detect hearing loss as defined in the study in adolescents.

description: We study the asymptotic behavior of the Hopf characteristic function of fractals and chaotic dynamical systems in the limit of large argument. The small argument behavior is determined by the moments, since the characteristic function is defined as their generating function. Less well known is that the large argument behavior is related to the fractal dimension. While this relation has been discussed in the literature, there has been very little in the way of explicit calculation. We attempt to fill this gap, with explicit calculations for the generalized Cantor set and the Lorenz attractor. In the case of the generalized Cantor set, we define a parameter characterizing the asymptotics which we show corresponds exactly to the known fractal dimension. The Hopf characteristic function of the Lorenz attractor is computed numerically, obtaining results which are consistent with Hausdorff or correlation dimension, albeit too crude to distinguish between them.

Angle-resolved photoemission spectroscopy studies of Tl₂Ba₂CuO₆+δ and YBa₂Cu₃O₇-δ : analysis of recent results and the construction of a new system

description: Recent angle-resolved photoemission spectroscopy (ARPES) results, from experiments performed at the Swiss Light Source, Stanford Synchrotron Radiation Lightsource, and Advanced Light Source synchrotrons, on the high-temperature superconductors Tl₂Ba₂CuO₆+δ (Tl2201) and YBa₂Cu₃O (YBCO₆.₅) are presented. An overdoped Tl2201 sample with a TC of 30K was found to have a Fermi surface, consisting of a large hole pocket centred at (Pi ,Pi ), which is approaching a topological transition. A superconducting gap consistent with a dχ₂−y₂ order parameter was detected. In contrast with the underdoped HTSCs, where the quasiparticle (QP) linewidth at the top of the band is maximal in the antinodal direction and minimal in the nodal direction, overdoped Tl2201 was revealed to have a reverse nodal-antinodal anisotropy, with sharp QP peaks in the antinodal region and broader peaks in the nodal region. The Tl2201 results establish Tl2201 as a valuable material for exploring the overdoped side of the phase diagram with ARPES. Synchrotron experiments also yielded the first successful ARPES results on underdoped YBa₂Cu₃O₇−δ (YBCO). Surface-sensitive techniques were previously unsuccessful in studying YBCO because its cleaved surfaces are polar, resulting in an overdoped surface regardless of the doping level of the bulk. By doping the cleaved surfaces with potassium, the surface was progressively hole underdoped from as-cleaved continuously to the doping of the bulk, and subsequent ARPES experiments performed revealed a transition from a holelike Fermi surface on the as-cleaved surface to disconnected Fermi arcs when the surface doping matched the bulk. In parallel with the synchrotron-based research, an in-house ARPES system was constructed at the University of British Columbia (UBC). Unlike conventional ARPES systems, the ARPES setup at UBC incorporates a molecular beam epitaxy (MBE) system, which allows novel materials to be grown, characterized, and transferred to the ARPES chamber in vacuo. Novel design techniques to improve the accuracy of ARPES measurements are presented. The in-house ARPES system also serves as a prototype for an ARPES–MBE endstation being constructed at the Canadian Light Source (CLS). Design studies of some potential improvements to the in-house system, to be implemented at the CLS, are also presented.

description: We study theoretically the combined effect of the spin-orbit and Zeeman interactions on the tunneling electron transport through a single-channel quantum ring threaded by magnetic flux. We focus on the high temperature case (temperature is much higher than the level spacing in the ring) and demonstrate that spin-interference effects are not suppressed by thermal averaging. In the absence of the Zeeman coupling the high-temperature tunneling conductance of the ring exhibits two types of oscillations: Aharonov-Bohm oscillations with magnetic flux and Aharonov-Casher oscillations with the strength of the spin-orbit interaction. For weak tunneling coupling both oscillations have the form of sharp periodic antiresonances. In the vicinity of the antiresonances the tunneling electrons acquire spin polarization, so that the ring serves as a spin polarizer. We also demonstrate that the Zeeman coupling leads to appearance of two additional peaks both in the tunneling conductance and in the spin polarization.

description: Constructions of metrics with special holonomy by methods of exterior differential systems are reviewed and the interpretations of these construction as `flows' on hypersurface geometries are considered. It is shown that these hypersurface 'flows' are not generally well-posed for smooth initial data and counterexamples to existence are constructed.

description: Interpretations of Higgs searches critically involve production cross sections and decay probabilities for different analysis channels. Mixing effects can reduce production rates, while invisible decays can reduce decay probabilities. Both effects can transparently be quantified in Higgs systems where a visible Higgs boson is mixed with a hidden sector Higgs boson. Recent experimental exclusion bounds can be re-interpreted in this context as a sign for non-standard Higgs properties. Should a light Higgs boson be discovered, then our analysis will quantify how closely it may coincide with the Standard Model.

description: A method is described to probe high-scale physics in lower-energy experiments by employing sum rules in terms of renormalisation group invariants. The method is worked out in detail for the study of supersymmetry-breaking mechanisms in the context of the Minimal Supersymmetric Standard Model. To this end sum rules are constructed that test either specific models of supersymmetry breaking or general properties of the physics that underlies supersymmetry breaking, such as unifications and flavour-universality.

description: In this article we investigate the properties of the FLRW flat cosmological models in which the cosmic expansion of the Universe is affected by a dilaton dark energy (Liouville scenario). In particular, we perform a detailed study of these models in the light of the latest cosmological data, which serves to illustrate the phenomenological viability of the new dark energy paradigm as a serious alternative to the traditional scalar field approaches. By performing a joint likelihood analysis of the recent supernovae type Ia data (SNIa), the differential ages of passively evolving galaxies, and the Baryonic Acoustic Oscillations (BAOs) traced by the Sloan Digital Sky Survey (SDSS), we put tight constraints on the main cosmological parameters. Furthermore, we study the linear matter fluctuation field of the above Liouville cosmological models. In this framework, we compare the observed growth rate of clustering measured with those predicted by the current Liouville models. Performing a chi^2 statistical test we show that the Liouville cosmological model provides growth rates that match sufficiently well with the observed growth rate. To further test the viability of the models under study, we use the Press-Schechter formalism to derive their expected redshift distribution of cluster-size halos that will be provided by future X-ray and Sunyaev-Zeldovich cluster surveys. We find that the Hubble flow differences between the Liouville and the LambdaCDM models provide a significantly different halo redshift distribution, suggesting that the models can be observationally distinguished.

description: To understand the communicational and psychosocial effects of COVID-19 protective measures in real-life everyday communication settings. An online survey consisting of close-set and open-ended questions aimed to describe the communication difficulties experienced in different communication activities (in-person and telecommunication) during the COVID-19 pandemic. 172 individuals with hearing loss and 130 who reported not having a hearing loss completed the study. They were recruited through social media, private audiology clinics, hospitals and monthly newsletters sent by the non-profit organisation “Audition Quebec.” Face masks were the most problematic protective measure for communication in 75–90% of participants. For all in-person communication activities, participants with hearing loss reported significantly more impact on communication than participants with normal hearing. They also exhibited more activity limitations and negative emotions associated with communication difficulties. These results suggest that, in times of pandemic, individuals with hearing loss are more likely to exhibit communication breakdowns in their everyday activities. This may lead to social isolation and have a deleterious effect on their mental health. When interacting with individuals with hearing loss, communication strategies to optimise speech understanding should be used.
