A k-space method for nonlinear wave propagation
Creators: name: Jing, Yun

Publisher: name: arXiv

Subjects: subject: Mathematical Physics (math-ph)

description: A k-space method for nonlinear wave propagation in absorptive media is presented. The Westervelt equation is first transferred into k-space via Fourier transformation, and is solved by a modified wave-vector time-domain scheme [Mast et al., IEEE Tran. Ultrason. Ferroelectr. Freq. Control 48, 341-354 (2001)]. The present approach is not limited to forward propagation or parabolic approximation. One- and two-dimensional problems are investigated to verify the method by comparing results to the finite element method. It is found that, in order to obtain accurate results in homogeneous media, the grid size can be as little as two points per wavelength, and for a moderately nonlinear problem, the Courant-Friedrichs-Lewy number can be as small as 0.4. As a result, the k-space method for nonlinear wave propagation is shown here to be computationally more efficient than the conventional finite element method or finite-difference time-domain method for the conditions studied here. However, although the present method is highly accurate for weakly inhomogeneous media, it is found to be less accurate for strongly inhomogeneous media. A possible remedy to this limitation is discussed.
Unhealthy lifestyle or modern disease? Constructing narcotic addiction and its treatments in the United States (1870-1920)
Creators: name: Delcourt, Irène
Publisher: name: The Journal of Somaesthetics
Year: 2020

description: The nature and management of narcotic addiction, and by extension, the nature and management of those who struggle with it, are not recent issues in the United States. Despite the current opioid epidemics and the apparent discovery of prescription-drug addiction, medical treatment of opioid dependence is already more than 100 years old. Is compulsive drug consumption a vice? A disease? A lifestyle? How does it affect the minds and bodies of those who suffer from it? How can they be cured? In the 1870s, physicians were already struggling with such questions when they pioneered what would become known as “addictology” in the 20th century. This article first endeavors to retrace the emergence of the conceptualization and perception of opiate addiction in the late 19th and early 20th centuries. From “imported vice” to “unhealthy lifestyle” and finally “nervous disease”, narcotic dependence became an increasingly important source of concern for turn-of-the-century physicians, precipitating a rapid and sometimes dangerously disjointed medicalization. This study then explores the different facets of early addiction treatments, their philosophies, their views on “addicted bodies” (particularly through the lens of lifestyle and heredity), and their impact on the evolution of addiction management programs.

Quantitative atomic spectroscopy for primary thermometry

description: Quantitative spectroscopy has been used to measure accurately the Doppler-broadening of atomic transitions in $^{85}$Rb vapor. By using a conventional platinum resistance thermometer and the Doppler thermometry technique, we were able to determine $k_B$ with a relative uncertainty of $4.1\times 10^{-4}$, and with a deviation of $2.7\times 10^{-4}$ from the expected value. Our experiment, using an effusive vapour, departs significantly from other Doppler-broadened thermometry (DBT) techniques, which rely on weakly absorbing molecules in a diffusive regime. In these circumstances, very different systematic effects such as magnetic sensitivity and optical pumping are dominant. Using the model developed recently by Stace and Luiten, we estimate the perturbation due to optical pumping of the measured $k_B$ value was less than $4\times 10^{-6}$. The effects of optical pumping on atomic and molecular DBT experiments is mapped over a wide range of beam size and saturation intensity, indicating possible avenues for improvement. We also compare the line-broadening mechanisms, windows of operation and detection limits of some recent DBT experiments.
What the Drug Culture Meant
Creators: name: Sartwell, Crispin
Publisher: name: The Journal of Somaesthetics
Year: 2020

description: For American kids in the 1970s, the term "drugs" referred to more than chemical compounds or plant extracts, more than a disease or a relief. Drugs, particularly marijuana and psychedelics, had cultural and counter-cultural meaning; they were, for us, symbols of the fact that we were different sorts of people than our parents and principals and political leaders: more open-minded, as it were, and more adventurous. Drugs were aesthetic (they affected our music and design arts and our heads fundamentally) and they were political, signaling anti-authoritarianism or an entire rejection of "the establishment." The term 'drug culture' is a sensible representation of the scope of the symbolic and economic activity; the drug culture was our native land. It was a resistant ethos, with rituals and sacred texts (by Abbie Hoffman, Timothy Leary, and Carlos Castaneda, for example), an underground world featuring, let's say, a third of the American population. We staked way too much of our lives and identities on substance abuse, I admit, gave drugs a symbolic weight that they cannot and really should not bear. But the power of the drug culture was in large measure derived from the sheer fact of illegality. In being part of it, each of us was a criminal, and we were all criminals together. That what we were doing was illegal is part of what made it seem, for a time, like a form of resistance.

description: During the last decade, lattice-Boltzmann (LB) simulations have been improved to become an efficient tool for determining the permeability of porous media samples. However, well known improvements of the original algorithm are often not implemented. These include for example multirelaxation time schemes or improved boundary conditions, as well as different possibilities to impose a pressure gradient. This paper shows that a significant difference of the calculated permeabilities can be found unless one uses a carefully selected setup. We present a detailed discussion of possible simulation setups and quantitative studies of the influence of simulation parameters. We illustrate our results by applying the algorithm to a Fontainebleau sandstone and by comparing our benchmark studies to other numerical permeability measurements in the literature.

Steps towards a tunable vacuum ultraviolet light source for TR-ARPES
Creators: name: Cross, Martin
Publisher: name: University of British Columbia
Year: 2019

description: We detail the steps towards a tunable vacuum ultraviolet light source for time-– and angle–resolved photo emission spectroscopy (TR-ARPES); specifically, the construction and characterization of a ytterbium–fiber based pump source, and a nonlinear broadening and compression stage using gas–filled hollow–core fiber (HCF). The ultimate goal is generating sub–30 fs pulses with photon energies between 5 eV and 11 eV via resonant dispersive wave (RDW) generation in a succeeding HCF. The interim goal discussed herein is producing 30 fs, infrared (∼ 1 µm), pulses with sufficient energy (µW level) for RDW generation. Using second harmonic generation (SHG) frequency resolved optical gating (FROG) we currently measure 174 fs, 4.0 µJ pulses. We will provide explanations for the shortcoming and suggest several possible solutions to address it.

description: Palm oil industry produces millions of tonnes of industrial wastes and these wastes create huge storage and environmental problems. In order to solve these problems various research works have been performed for past decades. The commonly available wastes are Oil palm shells (OPS), Palm oil clinker (POC) and Palm oil fuel ash (POFA). These materials have already acquired well recognition as alternate of conventional construction materials. OPS has been used as coarse aggregate and compressive strength was found up to 56 MPa for 56-day. It is said that 30 grade Oil Palm shell concrete (OPSC) is possible without adding any cementitious materials. The maximum modulus of elasticity for OPSC was found 18.6 GPa. The Oil palm shell concrete (OPSC) are used for drain blocks, road-kerbs and house where the palm oil factories are available. In case of superstructure like beams and slab are also produced by utilizing OPS. POC maintained the desired range of strength and density of structural lightweight concrete. The mechanical properties of POC has been evaluated through the research work. Their main aftermath is that the POC has been categorized as a structural lightweight concrete in accordance with the requirements of the ASTM: C330 and BS8110. Many experimental works have been performed to establish POFA as a substituting binding material in replace of Ordinary Portland cement (OPC). Throughout the research it has been showed that up to 20% of cement by mass can be replaced by POFA. POFA is one of the most enriched pozzolanic materials. The main purpose of this review is to discuss the usage and opportunity of the palm oil industrial wastes as construction materials following the previous experimental research work.
The Body is a Soft Machine: The Twisted Somaesthetic of William S. Burroughs
Creators: name: Jones, Robert
Publisher: name: The Journal of Somaesthetics
Year: 2020

description: This article explores the role of the body in William S. Burroughs's novels Junky (1959), The Soft Machine (1961, revised 1966 and 1968), The Ticket That Exploded (1962, revised 1967), and Nova Express (1964), of which the latter three comprise the Nova or Cut-Up Trilogy. The links between Burroughs's work and the fringe sciences and philosophies which he pursued for much of his life, are clear within his oeuvre. The fringe areas he studied most ardently include Alfred Korzybski's General Semantics, Wilhelm Reich's orgone theory, and the Scientology of L. Ron Hubbard, all of which examine control mechanisms of body and mind. This article shows that Burroughs's texts stand up not only as avant-garde literature but also as philosophical texts that outline a system to break free from control systems by exploiting the body/mind relationship. As such, this paper makes use of the tenets of Richard Shusterman's somaesthetics to provide a critical matrix with which to explore Burroughs's unique methods of investigating the body's role in achieving transcendence.

description: The SciBooNE Collaboration reports a measurement of inclusive charged current interactions of muon neutrinos on carbon with an average energy of 0.8 GeV using the Fermilab Booster Neutrino Beam. We compare our measurement with two neutrino interaction simulations: NEUT and NUANCE. The charged current interaction rates (product of flux and cross section) are extracted by fitting the muon kinematics, with a precision of 6-15% for the energy dependent and 3% for the energy integrated analyses. We also extract CC inclusive interaction cross sections from the observed rates, with a precision of 10-30% for the energy dependent and 8% for the energy integrated analyses. This is the first measurement of the CC inclusive cross section on carbon around 1 GeV. These results can be used to convert previous SciBooNE cross section ratio measurements to absolute cross section values.

description: Most bacteria swim through fluids by rotating helical flagella which can take one of twelve distinct polymorphic shapes. The most common helical waveform is the "normal" form, used during forward swimming runs. To shed light on the prevalence of the normal form in locomotion, we gather all available experimental measurements of the various polymorphic forms and compute their intrinsic hydrodynamic efficiencies. The normal helical form is found to be the most hydrodynamically efficient of the twelve polymorphic forms by a significant margin - a conclusion valid for both the peritrichous and polar flagellar families, and robust to a change in the effective flagellum diameter or length. The hydrodynamic optimality of the normal polymorph suggests that, although energetic costs of locomotion are small for bacteria, fluid mechanical forces may have played a significant role in the evolution of the flagellum.
New Gauge Field from Extension of Space Time Parallel Transport of Vector Spaces to the Underlying Number Systems

description: One way of describing gauge theories in physics is to assign a vector space $V_{x}$ to each space time point $x.$ For each $x$ the field $ψ$ takes values $ψ(x)$ in $V_{x}.$ The freedom to choose a basis in each $V_{x}$ introduces gauge group operators and their Lie algebra representations to define parallel transformations between vector spaces. This paper is an exploration of the extension of these ideas to include the underlying scalar complex number fields. Here a Hilbert space, $\bar{H}_{x},$ as an example of $V_{x},$ and a complex number field, $C_{x},$ are associated with each space time point. The freedom to choose a basis in $H_{x}$ is expanded to include the freedom to choose complex number fields. This expansion is based on the discovery that there exist representations of complex (and other) number systems that differ by arbitrary scale factors. Compensating changes must be made in the basic field operations so that the relevant axioms are satisfied. This results in the presence of a new real valued gauge field $\vec{A}(x).$ Inclusion of $\vec{A}(x)$ into covariant derivatives in Lagrangians results in the description of $\vec{A}(x)$ as a gauge boson that can have mass. The great accuracy of QED suggests that the coupling constant of $\vec{A}(x)$ to matter fields is very small compared to the fine structure constant. Other physical properties of $\vec{A}(x)$ are not known at present.

Innovative and conventional modelling for avian acoustic and fire severity analyses
Creators: name: Tseng, Yi-Chin
Publisher: name: University of British Columbia

description: Data science, the principles that support extracting knowledge from data, has become increasingly important in natural resources management. This thesis applied both machine learning (innovative modelling) and statistics (conventional modelling) to address two ecological questions. In Chapter 2, Automatic bird sound detection: logistic regression based acoustic occupancy model, logistic models and convolutional neural networks were applied to predict bird presence/absence in audio recordings, in order to improve efficiency in analyzing large audio datasets. The acoustic recordings came from a bird sound detection challenge organized by the Institute of Electrical and Electronics Engineers (IEEE) and covered bird songs and calls in a wide range of environments along with the presence of noise. Based on leave-one-out cross-validation, the final logistic model resulted in an overall accuracy of 75% with a false negative rate of 16%. Compared with a convolutional neural network (CNN) model using the same dataset, the logistic model was about seven times faster in terms of processing time. This bird sound detection model using sound frequency percentiles in a logistic model opens up promising approaches to aid in automatic, accurate, and efficient analysis of large audio datasets for monitoring wildlife communities. In Chapter 3, Previous fire severity enhances reburn severity: a case study in interior British Columbia, Canada, an ordinal logistic model was applied to investigate how previous fires influenced the reburn severity in interior British Columbia, Canada, in order to determine the driver of reburn severity. Previous fires affect rates of fuel consumption and accumulation, thus influencing the probability and severity of subsequent fires. In this study, forest stand structural change due to the first fire (in 2009 or 2010), such as changes in basal area and trees per hectare, were used to model the severity of the reburn in 2017. The ordinal model indicated a positive relationship between fire severities in the Riske Creek area. Specifically, fires in the Riske Creek area might not be able to limit the probability or severity of a reburn after seven or eight years.

description: Disturbances in gapless quantum many-body models are known to travel an unlimited distance throughout the system. Here, we explore this phenomenon in finite clusters with degenerate ground states. The specific model studied here is the one-dimensional J1-J2 Heisenberg Hamiltonian at and close to the Majumdar-Ghosh point. Both open and periodic boundary conditions are considered. Quenches are performed using a local magnetic field. The degenerate Majumdar-Ghosh ground state allows disturbances which carry quantum entanglement to propagate throughout the system, and thus dephase the entire system within the degenerate subspace. These disturbances can also carry polarization, but not energy, as all energy is stored locally. The local evolution of the part of the system where energy is stored drives the rest of the system through long-range entanglement. We also examine approximations for the ground state of this Hamiltonian in the strong field limit, and study how couplings away from the Majumdar-Ghosh point affect the propagation of disturbances. We find that even in the case of approximate degeneracy, a disturbance can be propagated throughout a finite system.

Power spectrum nulls due to non-standard inflationary evolution

description: The simplest models of inflation based on slow roll produce nearly scale invariant primordial power spectra (PPS). But there are also numerous models that predict radically broken scale invariant PPS. In particular, markedly cuspy dips in the PPS correspond to nulls where the perturbation amplitude, hence PPS, goes through a zero at a specific wavenumber. Near this wavenumber, the true quantum nature of the generation mechanism of the primordial fluctuations may be revealed. Naively these features may appear to arise from fine tuned initial conditions. However, we show that this behavior arises under fairly generic set of conditions involving super-Hubble scale evolution of perturbation modes during inflation. We illustrate this with the well-studied examples of punctuated inflation and the Starobinsky-break model.

Symmetry Content and Observation of Charged Collective Excitations for Graphene in Strong Magnetic Fields

description: We show that graphene in a strong magnetic field with partially filled Landau levels sustains charged collective excitations, which are bound states of three-particle complexes. Some of these states are optically bright and may be detected in spectroscopy experiments, enhancing the current understanding of electron-electron interactions in graphene. The states can be classified using the geometrical symmetries - non-commutative magnetic translations and generalized rotations - in addition to the dynamical SU(4) symmetry in graphene. From the SU(4) symmetry point of view, such excitations are analogous to bound states of two quarks and one antiquark qqqbar with four flavors. We establish a flavor optical selection rule to identify the bright states for experimental studies.

description: We present uniformly measured star formation histories (SFHs) of 60 nearby (D~4Mpc) dwarf galaxies based on CMDs of resolved stellar populations from images taken with HST as part of the ACS Nearby Galaxy Survey Treasury program (ANGST). This volume-limited sample contains 12 dSph/dE, 5 dwarf spiral, 28 dI, 12 transition, and 3 tidal dwarf galaxies. From the best fit SFHs we find three significant results: (1) the average dwarf galaxy formed >50% of its stars by z~2 and 60% of its stars by z~1, regardless of current morphological type; (2) the mean SFHs of dIs, dTrans, and dSphs are similar over most of cosmic time, with the clearest differences appearing during the most recent 1 Gyr; and (3) the mean values are inconsistent with simple SFH models, e.g., exponentially declining SFRs. The mean SFHs are in general agreement with the cosmic SFH, although we observe offsets near z~1 that could be evidence that low mass systems experienced delayed star formation relative to more massive galaxies. The sample shows a strong density-morphology relationship, such that the dSphs are less isolated than dIs. We find that the transition from a gas-rich to gas-poor galaxy cannot be solely due to internal mechanisms such as stellar feedback, and instead is likely the result of external mechanisms, e.g., ram pressure and tidal forces. The average transition dwarf is slightly less isolated and less gas-rich than the typical dI. Further, the transition dwarfs can be divided into two groups: interacting and gas-poor or isolated and gas-rich, suggesting two possible evolutionary pathways.

description: We study reconstruction of the lensing potential power spectrum from CMB temperature data, with an eye to the Planck experiment. We work with the optimal quadratic estimator of Okamoto and Hu, which we characterize thoroughly in application to reconstruction of the lensing power spectrum. We find that at multipoles L<250 our current understanding of this estimator is biased at the 15% level by beyond-gradient terms in the Taylor expansion of lensing effects. We present the full lensed trispectrum to fourth order in the lensing potential to explain this effect. We show that the low-L bias, as well as a previously known bias at high-L, is relevant to the determination of cosmology and must be corrected for in order to avoid significant parameter errors. We also investigate the covariance of the reconstructed power, finding broad correlations of ~0.1%. Finally, we discuss several small improvements which may be made to the optimal estimator to mitigate these problems.

description: We obtain the following analytical formula which describes the dependence of the electric potential of a point-like charge on the distance away from it in the direction of an external magnetic field B: Φ(z) = e/|z| [ 1- exp(-\sqrt{6m_e^2}|z|) + exp(-\sqrt{(2/π) e^3 B + 6m_e^2} |z|) ]. The deviation from Coulomb's law becomes essential for B > 3πB_{cr}/α= 3 πm_e^2/e^3 \approx 6 10^{16} G. In such superstrong fields, electrons are ultra-relativistic except those which occupy the lowest Landau level (LLL) and which have the energy epsilon_0^2 = m_e^2 + p_z^2. The energy spectrum on which LLL splits in the presence of the atomic nucleus is found analytically. For B > 3 πB_{cr}/α, it substantially differs from the one obtained without accounting for the modification of the atomic potential.

Suicide, Dangers to Self and Social Bodies: Taboo, Biopower, and Parental Worry in the Films Bridgend (2015) and Bird Box (2018)
Creators: name: Kosonen, Heidi
Publisher: name: The Journal of Somaesthetics
Year: 2020

description: In my article I study two Anglophone feature films, Jeppe Rønde's Bridgend (2015) and Susan Bier's Bird Box (2018), from the viewpoints offered by visual cultural studies and the theoretical domains of taboo and biopower. Both systems of control respond to risks and dangers to society, taboo through ideas of contagion and biopower through normative, especially medical discourses by authorized instances of knowledge production. They are reflected also in the audio-visual popular culture seeking to make sense of suicide through entertaining and artistic means. The two films I study present suicide as a contagion that has supernatural (Bird Box) and social origins (Bridgend), and as a force of nature that threatens individuals from the outside yet also from within as madness (Bird Box), or as irrationality or vulnerability of youth (Bridgend). By analyzing suicide's representation in both films, I discuss the ways western thinking trying to fathom voluntary death reflects senses of danger attached to suicide under taboo and biopower and in response to the humane emotions of love and fear of loss. I also discuss how taboo and biopower can be seen to generate this threat to individual lives by their suppression of living and dying.
