description: The linear sigma model with quarks at very low temperatures provides an effective description for the thermodynamics of the strong interaction in cold and dense matter, being especially useful at densities found in compact stars and protoneutron star matter. Using the MSbar one-loop effective potential, we compute quantities that are relevant in the process of nucleation of droplets of quark matter in this scenario. In particular, we show that the model predicts a surface tension of Σ~ 5-15 MeV/fm^2, rendering nucleation of quark matter possible during the early post-bounce stage of core collapse supernovae. Including temperature effects and vacuum logarithmic corrections, we find a clear competition between these features in characterizing the dynamics of the chiral phase conversion, so that if the temperature is low enough the consistent inclusion of vacuum corrections could help preventing the nucleation of quark matter during the collapse process. We also discuss the first interaction corrections that come about at two-loop order.

description: The experimental search limit on the Higgs boson mass points to a "golden region" in the Minimal Supersymmetric Standard Model parameter space in which the fine-tuning in the electroweak sector is minimized. One of the sbottoms is relatively light since its mass parameter is related to that of the stop. The decay products of the light sbottom typically include a W boson and a b jet. We studied the pair production of the light sbottoms at the Large Hadron Collider and examined its discovery potential via collider signature of 4 jets + 1 lepton + missing E_T. We analyzed the Standard Model backgrounds for this channel and developed a set of cuts to identify the signal and suppress the backgrounds. We showed that with 100 fb^{-1} integrated luminosity, a significant level of 5 sigma could be reached for the light sbottom discovery at the LHC.

description: The increasing precision of astronomical observations of stars and stellar systems is gradually getting to a level where the use of slightly different values of the solar mass, radius and luminosity, as well as different values of fundamental physical constants, can lead to measurable systematic differences in the determination of basic physical properties. An equivalent issue with an inconsistent value of the speed of light was resolved by adopting a nominal value that is constant and has no error associated with it. Analogously, we suggest that the systematic error in stellar parameters may be eliminated by: (1) replacing the solar radius Rsun and luminosity Lsun by the nominal values that are by definition exact and expressed in SI units: 1 RnomSun = 6.95508 x 10^8 m and 1 LnomSun = 3.846 x 10^{26} W; (2) computing stellar masses in terms of Msun by noting that the measurement error of the product G.Msun is 5 orders of magnitude smaller than the error in G; (3) computing stellar masses and temperatures in SI units by using the derived values Msun(2010) = 1.988547 x 10^{30} kg and Tsun(2010) = 5779.57 K; and (4) clearly stating the reference for the values of the fundamental physical constants used. We discuss the need and demonstrate the advantages of such a paradigm shift.

The time course of the analgesic effect of acupuncture in the treatment of lateral epicondylalgia : a randomized controlled feasibility trial comparing standard acupuncture and electroacupuncture
Creators: name: Jeon, Jaewon
Publisher: name: University of British Columbia
Year: 2016

description: Background: Resistance exercise is effective in relieving pain and improving grip strength in patients with lateral epicondylalgia (LE). However, patients’ activity-related pain can hinder their active participation in an exercise program. Acupuncture, particularly electro-acupuncture (EA), may be an effective complementary modality for pain control in order to promote patients’ participation in an exercise program and further to enhance therapeutic effects. Objectives: 1) assess the feasibility of a study designed to compare the effect size of analgesia induced by EA vs. standard acupuncture (SA); 2) estimate the time course of the analgesic effect of EA and SA for patients with LE; and 3) investigate if the analgesic effect of either intervention is associated with a change in pain-free grip strength. Methods: A double-blind, parallel-group randomized controlled feasibility trial was conducted at a research centre located in Vancouver, Canada. Twenty-one participants with unilateral LE lasting more than 6 weeks duration were enrolled in the study. The participants were randomly allocated to receive a single treatment of either EA (10-30 Hz) or SA. The primary outcome measure was pain-free grip strength, and the secondary outcome measures included the severity of lateral elbow pain (numeric rating scale), and patients’ global rating of change. Outcomes were measured over a 72-hour period. Results: No significant differences in outcome measures were found between the two treatment groups at any time point. A pattern of gradual improvement of pain-free grip strength (approximately 12N /day) over the 72-hour monitoring period in both treatment groups was observed, and this improvement was statistically significant compared to baseline at the 72-hour time point (38 ± 13N). In contrast, there was a statistically significant reduction in patients’ perceived pain level immediately after either treatment, and this improvement was maintained throughout the 72-hour follow-up period (-0.99~-1.59 ± 0.35). After 24 hours, 5% of patients reported themselves as feeling ‘much better’, 55% ‘slightly better’, 15% ‘unchanged’, 10% ‘slightly worse’, 10% ‘moderately worse’ and 5% ‘much worse’. Conclusion: Acupuncture may complement the therapeutic effect of rehabilitation exercise program as it provides immediate pain relief for patients with chronic LE.

description: Background: The first hour of a shift in a mine is characterized by a large movement of miners from incoming and outgoing shifts, in addition to safety and maintenance checks of mining equipment. These activities rely on communication to ensure a safe transition between shifts. This study aims to identify risk factors for injury among miners during the first hour of a work shift and characterize injury outcomes. Methods: Data from U.S. MSHA Part 50 reports, 1983-2015, were used to identify injuries occurring within the first hour of a shift. Multivariable logistic regression was used to evaluate predictors of injuries occurring during the first shift hour and to assess the outcome of these injuries. Results: Out of the 545,537 cases included in the analysis, 16,446 injuries occurred during the first hour of a shift. Risk factors associated with these injuries included being female, being older, working on Sunday and Monday, having an irregular shift start, working night shifts, employed in surface mining operations and mine operators with less than 200 employees, and mechanisms of injury related to falls, movement of equipment and personnel, and struck by/caught between boxes and containers. Injurious incidents occurring during the first hour of work were associated with mass injury events involving five or more workers. Conclusions: Although the injury rates were substantially lower during the first hour of work compared to all other work hours, this study identified risk factors and mechanisms of injury that are highly preventable during the first hour of work.

description: The matrix-valued spherical functions for the pair (K x K, K), K=SU(2), are studied. By restriction to the subgroup A the matrix-valued spherical functions are diagonal. For suitable set of representations we take these diagonals into a matrix-valued function, which are the full spherical functions. Their orthogonality is a consequence of the Schur orthogonality relations. From the full spherical functions we obtain matrix-valued orthogonal polynomials of arbitrary size, and they satisfy a three-term recurrence relation which follows by considering tensor product decompositions. An explicit expression for the weight and the complete block-diagonalization of the matrix-valued orthogonal polynomials is obtained. From the explicit expression we obtain right-hand sided differential operators of first and second order for which the matrix-valued orthogonal polynomials are eigenfunctions. We study the low-dimensional cases explicitly, and for these cases additional results, such as the Rodrigues formula and being eigenfunctions to first order differential-difference and second order differential operators, are obtained.

description: In the buyback problem, an algorithm observes a sequence of bids and must decide whether to accept each bid at the moment it arrives, subject to some constraints on the set of accepted bids. Decisions to reject bids are irrevocable, whereas decisions to accept bids may be canceled at a cost that is a fixed fraction of the bid value. Previous to our work, deterministic and randomized algorithms were known when the constraint is a matroid constraint. We extend this and give a deterministic algorithm for the case when the constraint is an intersection of $k$ matroid constraints. We further prove a matching lower bound on the competitive ratio for this problem and extend our results to arbitrary downward closed set systems. This problem has applications to banner advertisement, semi-streaming, routing, load balancing and other problems where preemption or cancellation of previous allocations is allowed.

description: We probe the cosmic acceleration by using the recently released SNLS3 sample of 472 type Ia supernovae. Combining this type Ia supernovae dataset with the cosmic microwave background anisotropy data from the Wilkinson Microwave Anisotropy Probe 7-yr observations, the baryon acoustic oscillation results from the Sloan Digital Sky Survey data release 7, and the Hubble constant measurement from the Wide Field Camera 3 on the Hubble Space Telescope, we measure the dark energy equation of state $w$ and the deceleration parameter $q$ as functions of redshift by using the Chevallier-Polarski-Linder parametrization. Our result is consistent with a cosmological constant at 1$σ$ confidence level, without evidence for the recent slowing down of the cosmic acceleration. Furthermore, we consider three binned parametrizations ($w$ is piecewise constant in redshift $z$) based on different binning methods. The similar results are obtained, i.e., the $Λ$CDM model is still nicely compatible with current observations.

description: We consider a bosonic Josephson junction made of $N$ ultracold and dilute atoms confined by a quasi one-dimensional double-well potential within the two-site Bose-Hubbard model framework. The behaviour of the system is investigated at zero temperature by varying the inter-atomic interaction from the strongly attractive regime to the repulsive one. We show that the ground-state exhibits a crossover from a macroscopic Schrödinger-cat state to a separable Fock state through an atomic coherent regime. By diagonalizing the Bose-Hubbard Hamiltonian we characterize the emergence of the mascroscopic cat states by calculating the Fisher information $F$, the coherence by means of the visibility $α$ of the interference fringes in the momentum distribution, and the quantum correlations by using the entanglement entropy $S$. Both Fisher information and visibility are shown to be related to the ground state energy by employing the Hellmann-Feynman theorem. This result, together with a perturbative calculation of the ground-state energy, makes possible to obtain simple analytical formulas for $F$ and $α$ over a range of interactions, in excellent agreement with the exact diagonalization of the Bose-Hubbard Hamiltonian. In the attractive regime the entanglement entropy attains values very close to its upper limit for a specific interaction strength lying in the region where coherence is lost and self trapping sets in.

description: Tensile tests were carried out by deforming polycrystalline samples of Al-2.5%Mg alloy at four different temperatures in an intermediate strain rate regime of 2x10-4s-1 to 2x10-3s-1. The Portevin-Le Chatelier (PLC) effect was observed throughout the strain rate and temperature region. The mean cumulative stress drop magnitude and the mean reloading time exhibit an increasing trend with temperature which is attributed to the enhanced solute diffusion at higher temperature. The observed stress-time series data were analyzed using the nonlinear dynamical methods. From the analyses, we could establish the presence of deterministic chaos in the PLC effect throughout the temperature regime. The dynamics goes to higher dimension at a sufficiently high temperature of 425K but the complexity of the dynamics is not affected by the temperature.

description: In some recent papers by Tamura, Tanaka and Kawashima [arXiv:1102.5475, arXiv:1012.4254], a class of Potts models with "invisible" states was introduced, for which the authors argued by numerical arguments and by a mean-field analysis that a first-order transition occurs. Here we show that the existence of this first-order transition can be proven rigorously, by relatively minor adaptations of existing proofs for ordinary Potts models. In our argument we present a random-cluster representation for the model, which might be of independent interest.

Time and Again: Old Women and Care Workers Navigating Time, Relationality, and Power in Dementia Units
Creators: name: Yoshizaki-Gibbons, Hailee Marie
Publisher: name: University of Illinois at Chicago

description: In the United States, there are nearly one million old disabled women living in nursing homes, approximately seventy percent of whom are diagnosed with Alzheimer’s disease and other forms of dementia. The vast majority of their direct care workers are also women, and many are further marginalized by race, class, and immigrant status. Despite this, little is known about the lived experiences of old women with dementia and care workers in nursing homes. This project centers the care relationships between institutionalized old women with dementia and the immigrant women of color employed to care for them. Drawing on nine months of ethnographic research in the dementia unit of a nursing home, I focus on temporality as a framework to understand the complex ways care is conceptualized, structured, and enacted within the confines of the unit. I analyze how time simultaneously operates to reproduce gendered, racialized, classed, aged, and disability oppressions and serves as a site of solidarity, community-building, and resistance among old women with dementia and their caregivers. I argue that while bureaucratic and institutional time serve as a nexus of power and a pervasive organizing principle of care structures and relations within nursing homes, old women with dementia and their caregivers disrupt these normative, dominant, and linear approaches to temporality. They do this by slowing institutional time to “make time” for connectivity, engaging in circular and repetitive forms of relationship building, and existing together in what I term “dementia time,” which is a temporal dis/orientation that explores alternate spacetimes and realities and finds meaning and value in self-contained, nonlinear, intermittent, irrational, and idiosyncratic moments. This research has theoretical and applied implications regarding how disability, aging, and feminist studies understand temporal constructions of care and how a more just system of care might be enacted for multiply marginalized women giving and receiving care in dementia units.
Resonant alteration of propagation in guiding structures with complex Robin parameter and its magnetic-field-induced restoration

description: Solutions of the scalar Helmholtz wave equation are derived for the analysis of the transport and thermodynamic properties of the two-dimensional disk and three-dimensional infinitely long straight wire in the external uniform longitudinal magnetic field $\bf B$ under the assumption that the Robin boundary condition contains extrapolation length $Λ$ with nonzero imaginary part $Λ_i$. As a result of this complexity, the self-adjointness of the Hamiltonian is lost, its eigenvalues $E$ become complex too and the discrete bound states of the disk characteristic for the real $Λ$ turn into the corresponding quasibound states with their lifetime defined by the eigenenergies imaginary parts $E_i$. Accordingly, the longitudinal flux undergoes an alteration as it flows along the wire with its attenuation/amplification being $E_i$-dependent too. It is shown that, for zero magnetic field, the component $E_i$ as a function of the Robin imaginary part exhibits a pronounced sharp extremum with its magnitude being the largest for the zero real part $Λ_r$ of the extrapolation length. Increasing magnitude of $Λ_r$ quenches the $E_i-Λ_i$ resonance and at very large $Λ_r$ the eigenenergies $E$ approach the asymptotic real values independent of $Λ_i$. The extremum is also wiped out by the magnetic field when, for the large $B$, the energies tend to the Landau levels. Mathematical and physical interpretations of the obtained results are provided; in particular, it is shown that the finite lifetime of the disk quasibound states stems from the $Λ_i$-induced currents flowing through the sample boundary. Possible experimental tests of the calculated effect are discussed; namely, it is argued that it can be observed in superconductors by applying to them the external electric field $\cal E$ normal to the surface.

description: The OSI model, developed by ISO in 1984, attempts to summarize complicated network cases on layers. Moreover, network troubles are expressed by taking the model into account. However, there has been no standardization for network troubles up to now. Network troubles have only been expressed by the name of the related layer. In this paper, it is pointed out that possible troubles on the related layer vary and possible troubles on each layer are categorized for functional network administration and they are standardized in an eligible way. The proposed model for network trouble shooting was developed considering the OSI model.

description: Falls lead to detrimental injuries such as fractures, and death in old age. The frequent occurrence of falls leads to increased fear of falls, less participation in physical activities, deconditioning and the increased incidence of co-morbidities such as hypertension and diabetes mellitus. Among others, the integrated dance-based exergaming is an emerging paradigm, which is readily available to all populations, including older adults, thereby increasing practice sessions that leads to potential improvements in balance, mobility and physical fitness. It is therefore critical to understand the important variables of assessment, the effectiveness of dance training and the tools for in-home assessment of performance of dance training as the benefits of dance is translated to the clinics, homes and communities of older adults. The studies in this dissertation examined the effect of dance-based exergaming on movement kinematics and physical functioning in old age and the validity of an assessment tool aiding in seamless translation of the benefits of dance to the clinics, homes and communities. Young (18-35 years) and older (≥ 60 years) participants underwent a dance-based assessment protocol for postural stability and mobility with three song paces. Additionally, older adults (≥ 65 years) with MCI completed a 15-session dance-based exergaming with 10 alternate slow and fast-pace songs. Lastly, for translation of the paradigm, concurrent validity test of inertial sensors and motion capture systems (MOCAP) was conducted. This dissertation was developed assessment protocol of dance-based exergaming and showed that young participants had increases in baseline center of mass sway area, excursions and joint excursions than in the older participants. The dosage of 15 sessions of dance-based exergaming led to increased feasibility and adherence rate comparable to similar studies, improvements in cognitive, gait functions, and increased stability, reduced fall rates and physical fitness in older adults with MCI. Also, inertial sensors depicted high validity and reliability similar to MOCAP. On account of feasibility and effectiveness of dance-based exergaming and increased validity of inertial sensors, an established assessment protocol may determine the improvements in outcomes during dance and provide confidence in translating the benefits dance-based exergaming to the clinics, homes and communities of older adults.

description: We study the spectrum of BPS D-branes on a Calabi-Yau manifold using the 0+1 dimensional quiver gauge theory that describes the dynamics of the branes at low energies. The results of Kontsevich and Soibelman predict how the degeneracies change. We argue that Seiberg dualities of the quiver gauge theories, which change the basis of BPS states, correspond to crossing the "walls of the second kind." There is a large class of examples, including local del Pezzo surfaces, where the BPS degeneracies of quivers corresponding to one D6 brane bound to arbitrary numbers of D4, D2 and D0 branes are counted by melting crystal configurations. We show that the melting crystals that arise are a discretization of the Calabi-Yau geometry. The shape of the crystal is determined by the Calabi-Yau geometry and the background B-field, and its microscopic structure by the quiver Q. We prove that the BPS degeneracies computed from Q and Q' are related by the Kontsevich Soibelman formula, using a geometric realization of the Seiberg duality in the crystal. We also show that, in the limit of infinite B-field, the combinatorics of crystals arising from the quivers becomes that of the topological vertex. We thus re-derive the Gromov-Witten/Donaldson-Thomas correspondence.

Citizen Humanities as a Fusion of Digital and Public Humanities?
Creators: name: Heinisch, Barbara
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2020

description:

Digital and public humanities have gained a foothold in academia, but very little is known about citizen humanities, which is referring to the engagement of the general public in scholarly research. Although the term is new, public participation in the humanities, either as the citizens’ contribution of intellectual effort or knowledge to academic research, or as the contribution of resources and tools, looks back on a long tradition. The citizen humanities range from the creation of dictionaries, the transcription and annotation of historical records to the decoding of ancient Egyptian papyri. While the digital humanities provide the citizen humanities with data, tools and techniques, the public humanities offer the means of engaging diverse publics in research activities. After embedding the citizen humanities theoretically in the responsible research and innovation paradigm, this paper will illustrate how digitisation and public involvement laid the foundations for today’s citizen humanities. With a focus on the fusion of digital and public humanities in citizen humanities, this paper will demonstrate the mutual influence on practices (of research). This influence is not only reflected in the approaches to research, analysis, communication, and dissemination but also in the citizen humanities’ novel ways of knowledge co-production.

Using ultrasound to measure arterial diameter for the development of a wearable blood pressure monitoring device
Creators: name: Worthing, Richard Tyler
Publisher: name: University of British Columbia
Year: 2016

description: The goal of this thesis is to explore the potential of using ultrasound as part of a continuous and non-invasive blood pressure measurement device. Personal blood pressure measurement technology has remained relatively stagnant for decades, restricting those who take their blood pressure at home to using devices that operate with an inflatable pressure cuff. These devices are prohibitive in terms of both wearability and the ability to make measurements continuously. A device based on the methods explored in this thesis would be beneficial to anyone who requires at-home or 24-hour blood pressure monitoring without hindrance to daily activities, or blood pressure monitoring during exercise. In this thesis, a combination of ultrasound imaging and photoplethysmography are used to measure the diameter and the speed of a blood pulse traveling through the radial artery. Hemodynamic models suggest that these two metrics (arterial diameter and pulse wave velocity) are closely related to blood pressure and can be used to track changes in blood pressure at various points on the human body. To demonstrate proof of concept, two phases of a prototype device have been constructed. The first phase of the prototype makes use of an arterial phantom that simulates blood flow through an artificial artery immersed in a water bath. The purpose of the first prototype was to test the proposed method in a closed and controlled environment, using a non-destructive testing ultrasound probe for measuring the diameter of the phantom artery and pressure sensors for measuring the speed of a pressure pulse through the artery. The second phase of the prototype was built to perform measurements on human subjects. This stage used a medical ultrasound probe and photoplethysmography sensors to measure the diameter of the radial artery and local pulse wave velocity. Measurements with the phantom showed good correlation between the experimental method and absolute pressure measurement sensors. For human measurements, modelled blood pressure correlated well with values measured using a standard cuff-based blood pressure measurement device. Though the model showed good correlation with reference measurements, more work is needed on the prototype device before commercialization can be considered.

description:

This paper will construct a history of computational literary criticism (CLS) which has engaged statistical methods by providing an historical account of the journal articles as well as other publications which have advanced the field to the most significant extent since 1963. This paper divides the history of CLS into three distinct epochs, within each of which the methods and theories CLS scholars utilise undergo significant qualitative transformation. The decisive factor in each of these epochs is CLS’ relationship to traditional literary criticism. Partly as a result of this, CLS scholarship initially cleaves to organic theories of literary style and adopts a highly polemicised opposition to then-regnant post-structuralist theories of authorship.

description:

The relationship between history and information technology is long and troubled. Many projects have opened and closed, many pioneering initiatives have achieved success and attention, but often they have not ‘taught’ or left a fruitful legacy. These experiments, studies and conferences have built a rich basis for the relationship between the disciplines, but the difficult connection needs to be further explored. Although no digital history research centres exist in Italy nowadays, it is possible to look at several Italian projects in order to discuss the strange position of the digital issue within public history conferences, the place of history in the large digital humanities environment and finally the definition itself of digital history.

description: A method for a time-dependent search for flaring astrophysical sources which can be potentially detected by large neutrino experiments is presented. The method uses a time-clustering algorithm combined with an unbinned likelihood procedure. By including in the likelihood function a signal term which describes the contribution of many small clusters of signal-like events, this method provides an effective way for looking for weak neutrino flares over different time-scales. The method is sensitive to an overall excess of events distributed over several flares which are not individually detectable. For standard cases (one flare) the discovery potential of the method is about 15% worse than a standard time-dependent point source analysis with unknown duration of the flare. However, for flares sufficiently shorter than the total observation period, the method is more sensitive than a time-integrated analysis.

Digital Heritage Consumption: The Case of the Metropolitan Museum of Art

description:

Cultural consumption is increasingly moving into a digital realm where art and non-art spaces blur in an all-inclusive image-rich environment online. While cultural consumption studies remain limited to a defined cultural environment (e.g. the museum website), we will analyse the patterns of consumption of 119 paintings from the Metropolitan Museum of Art collection in an all-inclusive online environment, Wikipedia. We will find paintings in art as well as non-art related articles and compare visibility to the institutional physical and online exhibition, a purely art environment. We will find a greater share of digital cultural consumption takes place in non-art related articles, inferring accidental consumption, while fact-checking and the presence of articles about obscure paintings satisfy a utilitarian information use. We will argue that digital cultural consumption can expand the user base when positioned outside of the expected art context, enabling new forms of hedonic and utilitarian consumption. Our results suggest that the adoption of the online encyclopaedia by superstar museums reflects a new conceptualisation of authentic taste that includes digital consumption, highlighting the collection’s information value.

Temporal and spatial patterns of outmigration of juvenile sockeye salmon in Rivers Inlet
Creators: name: Egorova, Yulia
Publisher: name: University of British Columbia
Year: 2016

description: The sockeye salmon, Oncorhynchus nerka, is economically, ecologically and culturally important for British Columbia and Canada. Currently, ~75% of sockeye populations are declining with a precipitous decline reported in Rivers Inlet (RI). The purpose of this study was to investigate the variability of juvenile sockeye residence and growth in RI during their outmigration to the Pacific Ocean. The point of the marine entry was estimated by Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) using otolith elemental composition (Sr:Ca ratio). A significant correlation was found between the day of entry and the duration of the migration. Average transit time through the inlet was ~ 2 weeks in 2011 and 2009, compared to ~ 4 weeks in 2008 and 2010. In terms of BL/s, the fish travel through RI with an average speed of 0.2– 0.5 BL/s. The size of the smolts at the entry to the inlet ranged between 54 and 83 mm. Detailed analysis of the full outmigration period in 2009 identified two possible migration behaviors, dependent on the day of entry and potentially the size of the smolts. Smaller fish that entered the inlet prior to mid-June exhibited a “holding” pattern at the head of the inlet, with an average residence time of 2-3 weeks. Smolts that entered the inlet later in the season swam continuously throughout the inlet. Using GAM models, it was determined that 78% of the weight at catch and 64% increase in weight were explained by the combination of water temperature, freshwater discharge, zooplankton densities and inlet entry size of smolts. The duration of the outmigration was dependent on river discharge and temperature, with 62% of the variation in outmigration duration explained by the model. Results suggest that there is a set of optimal environmental conditions for smolt growth during their outmigration. Outmigration timing was found to be the key determinant of conditions experienced and appeared to act as an equilibration mechanism between small and large smolts, resulting in similar size being attained by both by the inlet mouth.

Tunneling spectra of strongly coupled superconductors: Role of dimensionality
Creators: name: Berthod, C.
Publisher: name: arXiv
Year: 2010
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: We investigate numerically the signatures of collective modes in the tunneling spectra of superconductors. The larger strength of the signatures observed in the high-Tc superconductors, as compared to classical low-Tc materials, is explained by the low dimensionality of these layered compounds. We also show that the strong-coupling structures are dips (zeros in the d2I/dV2 spectrum) in d-wave superconductors, rather than the steps (peaks in d2I/dV2) observed in classical s-wave superconductors. Finally we question the usefulness of effective density of states models for the analysis of tunneling data in d-wave superconductors.

Video Self-Modeling for Bilingual Children with Identified or Suspected Childhood Apraxia of Speech

description: The cultural and linguistic diversity of our nation continues to grow and the skills needed by speech-language pathologists to address the needs of their existing caseload continue to be vast. According to the ASHA (2016) Schools Survey, only 8% of speech-language pathologists (n=1689) reported feeling very qualified to address cultural and linguistic influences on service delivery outcomes. While the population of bilingual children with speech and language disorders continues to increase (ASHA, 2016), speech sound disorder interventions for English language learners, continue to be scarce across the literature. Although the prevalence of childhood apraxia of speech (CAS) specifically is unknown, speech sound disorders in general, are noted to be common developmental conditions affecting 2%-25% of children 5 to 7 years of age (Sices et al., 2007; ASHA, 2007). Moreover, it has been documented that CAS, a speech sound disorder, has increased substantially during the past decade due to birth to three legislative changes driving diagnosis based on possible erroneous behaviors, and increased information on the disorder (ASHA, 2007). The purpose of this study was to evaluate how a sensory cueing intervention model using a video self-modeling technique effected the speech production of developing bilingual children with identified or suspected childhood apraxia of speech. The effects of a sensory cueing intervention using a video self-model on the speech production tasks of developing bilingual (English/Spanish) children with suspected apraxia of speech was explored. A single case A-B-A-B withdrawal research design with repeated introduction and withdrawal of an intervention was used to evaluate causality of intervention across speech behaviors. This study utilized a video self-model with three, 3-5 year old developing bilingual children with identified or suspected apraxia of speech, across 26 sessions over a period of 8 weeks with a one week post intervention follow-up/maintenance phase. Within-condition analysis and between condition analysis were conducted to determine effect and change in condition on dependent variable (speech). The findings of this study showed that the video self-modeling sensory cueing intervention which contained a cross-linguistic approach to target selections and conducted in the Spanish language had an improving trend effect on the speech outcomes of preschool aged developing bilingual children identified with or suspected of CAS. Implications for practice, research and limitations are discussed.
A scaling theory for the size distribution of emitted dust aerosols suggests climate models underestimate the size of the global dust cycle

description: Mineral dust aerosols impact Earth's radiation budget through interactions with clouds, ecosystems, and radiation, which constitutes a substantial uncertainty in understanding past and predicting future climate changes. One of the causes of this large uncertainty is that the size distribution of emitted dust aerosols is poorly understood. The present study shows that regional and global circulation models (GCMs) overestimate the emitted fraction of clay aerosols (< 2 μm diameter) by a factor of ~2 - 8 relative to measurements. This discrepancy is resolved by deriving a simple theoretical expression of the emitted dust size distribution that is in excellent agreement with measurements. This expression is based on the physics of the scale-invariant fragmentation of brittle materials, which is shown to be applicable to dust emission. Because clay aerosols produce a strong radiative cooling, the overestimation of the clay fraction causes GCMs to also overestimate the radiative cooling of a given quantity of emitted dust. On local and regional scales, this affects the magnitude and possibly the sign of the dust radiative forcing, with implications for numerical weather forecasting and regional climate predictions in dusty regions. On a global scale, the dust cycle in most GCMs is tuned to match radiative measurements, such that the overestimation of the radiative cooling of a given quantity of emitted dust has likely caused GCMs to underestimate the global dust emission rate. This implies that the deposition flux of dust and its fertilizing effects on ecosystems may be substantially larger than thought.
