Death sentences : the modern ordering of mortality
Creators: name: Bayat Rizi, Zohréh
Publisher: name: University of British Columbia
Year: 2010

description: This project examines the introduction of death as a political-economic issue and its discursive problematization as a subject of sociological inquiry since the late seventeenth century. I draw from the works of Foucault, Baudrillard, Agamben, Bauman, and Parsons, among others, who argue that, in the past few centuries, the economy of death has been transformed from one that emphasizes the symbolic significance of death to one that treats death discursively as a medical and public health problem. This transformation (or tension, in my view) is underscored by the discovery of an interconnection between the way people die, on the one hand, and political order and economic prosperity, on the other hand. By the 'ordering of death' I mean a social framework for defining, dealing with, and regulating mortality. The notion of 'death sentences,' in the title, refers to the four commandments (orders) of the discursively regulated death: thou shalt not die violently, thou shalt not die prematurely, thou shalt not kill thyself, thou shalt not die an undignified death, all of which are synthesized in the commandment: thou shalt not die an un-orderly death. The commandment to die an orderly death is the common denominator and the positive expression of the four negative commandments governing modern death. 'Sentence' implies that such ordering is discursive, carried through sentences, words, figures, texts, and statistical tabulations. It also indicates that as in the ritual of death penalty, the management of death has is still to some extent symbolic. Hobbes' problematization of violent death as a political-economic concern, rather than a metaphysical or existential issue, was central to this process. His instrumental approach to knowledge greatly influenced discursive problematizations of other forms of death such as premature death and suicide first and foremost through the works of his immediate followers, John Graunt and Sir William Petty. By quantifying the existential experience of mortality, these authors played a crucial role in the development of statistical techniques for the study of other subjective and/or social experiences widely used in sociology today. Using evidence from England, France, Germany, and the Netherlands, I argue that the statistical problematization of suicide in the nineteenth century and the contemporary debate over policy approaches to euthanasia are in continuity with the logic of the positivist, objectivist, and instrumental approach to mortality pioneered by Hobbes and his followers. Therefore, how we die today can best be understood within the trajectory of an entire history of modern discourses that shape and define what it is to live or to die. In this sense, the history of modern forms of regulating death is a history of our present.

description: En este trabajo se presenta una aportación original en el ámbito del método de valoración conocido como «de las dos betas» (en general método de las dos funciones de distribución), como es sabido, en este método el valor de un activo se establece a través del valor de un índice de referencia seleccionado. El proceso exige estimar una función de distribución para el índice y otra para el activo. En primer lugar se cuestiona el acierto de los índices elegidos para valorar los activos, a continuación se analiza la adecuación de las distribuciones de probabilidad seleccionadas para simular el comportamiento del índice y del activo. Posteriormente se presentan varios tests estadísticos, desarrollados a propósito de este método de valoración, que permiten contrastar la representatividad de los índices y la adecuación de los modelos probabilísticos. El trabajo finaliza con una aplicación práctica sobre la valoración de parcelas agrícolas en el Campo de El Ejido (Almería), donde el activo a valorar es la hectárea de terreno agrícola y el índice es el ingreso anual por hectárea...In this work an original contribution in the fiel of the «two betas» valuation method (in general method of the two distribution functions) is presented. As it is well-known, in this method the value of an asset is deduced from the value of a chosen reference index. The process requires to estimate a distribution function for the index and another one for the asset. In first place, the success of the chosen index to value the asset is questioned; next, fit of the chosen probability distributions to simulate the behaviour both of the index and the asset is analysed. Later, several statistical tests for this valuation method are presented, that allow us to contrast the representative ness of the inex and the fitting of th probabilistic model. This paper finished with a practical application about the valuation of agricultural parcels in the Field of El Ejido (Almería, Spain), where the asset to be valued is the price of a hectare of agricultural land and the index is the annual income per hectare.

Quantum multipartite maskers vs quantum error-correcting codes

description: Since masking of quantum information was introduced by Modi et al. in [PRL 120, 230501 (2018)], many discussions on this topic have been published. In this paper, we consider relationship between quantum multipartite maskers (QMMs) and quantum error-correcting codes (QECCs). We say that a subset $Q$ of pure states of a system $K$ can be masked by an operator $S$ into a multipartite system $\H^{(n)}$ if all of the image states $S|ψ\>$ of states $|ψ\>$ in $Q$ have the same marginal states on each subsystem. We call such an $S$ a QMM of $Q$. By establishing an expression of a QMM, we obtain a relationship between QMMs and QECCs, which reads that an isometry is a QMM of all pure states of a system if and only if its range is a QECC of any one-erasure channel. As an application, we prove that there is no an isometric universal masker from $\C^2$ into $\C^2\otimes\C^2\otimes\C^2$ and then the states of $\C^3$ can not be masked isometrically into $\C^2\otimes\C^2\otimes\C^2$. This gives a consummation to a main result and leads to a negative answer to an open question in [PRA 98, 062306 (2018)]. Another application is that arbitrary quantum states of $\C^d$ can be completely hidden in correlations between any two subsystems of the tripartite system $\C^{d+1}\otimes\C^{d+1}\otimes\C^{d+1}$, while arbitrary quantum states cannot be completely hidden in the correlations between subsystems of a bipartite system [PRL 98, 080502 (2007)].

description: We demonstrate the relevance of entanglement, Bell inequalities and decoherence in particle physics. In particular, we study in detail the features of the ``strange'' $K^0 \bar K^0$ system as an example of entangled meson--antimeson systems. The analogies and differences to entangled spin--1/2 or photon systems are worked, the effects of a unitary time evolution of the meson system is demonstrated explicitly. After an introduction we present several types of Bell inequalities and show a remarkable connection to CP violation. We investigate the stability of entangled quantum systems pursuing the question how possible decoherence might arise due to the interaction of the system with its ``environment''. The decoherence is strikingly connected to the entanglement loss of common entanglement measures. Finally, some outlook of the field is presented.

The spectral evolution of impulsive solar X-ray flares

Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The time evolution of the spectral index and the non-thermal flux in 24 impulsive solar hard X-ray flares of GOES class M was studied in RHESSI observations. The high spectral resolution allows for a clean separation of thermal and non-thermal components in the 10-30 keV range, where most of the non-thermal photons are emitted. Spectral index and flux can thus be determined with much better accuracy than before. The spectral soft-hard-soft behavior in rise-peak-decay phases is discovered not only in the general flare development, but even more pronounced in subpeaks. An empirically found power-law dependence between the spectral index and the normalization of the non-thermal flux holds during the rise and decay phases of the emission peaks. It is still present in the combined set of all flares. We find an asymmetry in this dependence between rise and decay phases of the non-thermal emission. There is no delay between flux peak and spectral index minimum. The soft-hard-soft behavior appears to be an intrinsic signature of the elementary electron acceleration process.

description: Very few examples are known of red supergiant runaways, all of them descending from the more massive O-type precursors, but none from the lower mass B-type precursors, although runaway statistics among B-type stars suggest that K-type runaways must be relatively numerous. We study HD 137071, a star that has been considered so far as a normal K-type red giant. Its parallax measured by Gaia and the derived luminosity suggest that it is actually a supergiant, whereas its derived distance to the galactic plane and its spatial velocity of 54.1 km s$^{-1}$ with respect to the local standard of rest suggest that it is also a runaway star. However, intrinsic limitations in determining the trigonometric parallaxes of cool supergiants, even in the Gaia era, require accurate spectral classifications for confirmation. We reliably classify HD 137071 as a K4II star establishing its membership to the extreme Population I, which is in agreement with the luminosity derived using the Gaia DR2 parallax measurement. Kinematical data from the Gaia DR2 catalog confirm its high spatial velocity and its runaway nature. Combining the spectral classification with astrometric information, a state-of-the-art galactic potential model, and evolutionary models for high-mass stars we trace the motion of HD 137071 back to the proximities of the galactic plane and speculate on which of the two proposed mechanisms for the production of runaway stars may be responsible for the high velocity of HD 137071. The available data favor the formation of HD 137071 in a massive binary system where the more massive companion underwent a supernova explosion about 32 Myr ago.

description: The novel Corona Virus COVID-19 arrived on Australian shores around 25 January 2020. This paper presents a novel method of dynamically modeling and forecasting the COVID-19 pandemic in Australia with a high degree of accuracy and in a timely manner using limited data; a valuable resource that can be used to guide government decision-making on societal restrictions on a daily and/or weekly basis. The "partially-observable stochastic process" used in this study predicts not only the future actual values with extremely low error, but also the percentage of unobserved COVID-19 cases in the population. The model can further assist policy makers to assess the effectiveness of several possible alternative scenarios in their decision-making processes.

description: A numerical simulation is carried out for static vortices in a long Josephson junction with an exponentially varying width. At specified values of the parameters the corresponding boundary-value problem admits more than one solution. Each solution (distribution of the magnetic flux in the junction) is associated to a Sturm--Liouville problem, the smallest eigenvalue of which can be used, in a first approximation, to assess the stability of the vortex against relatively small spatiotemporal perturbations. The change in width of the junction leads to a renormalization of the magnetic flux in comparison with the case of a linear one-dimensional model. The influence of the model parameters on the stability of the states of the magnetic flux is investigated in detail, particularly that of the shape parameter. The critical curve of the junction is constructed from pieces of the critical curves for the different magnetic flux distributions having the highest critical currents for the given magnetic field.

Este modelo también se ha adaptado a la planificación de actividades en contexto de riesgo, particularmente a la planificación de cultivos en España. La aplicación a la selección de carteras de inversión en tierras de uso agrario en España es posible gracias a una progresiva mejora del nivel de información sobre el mercado de la tierra. La detección de altos niveles de correlación en la rentabilidad de las inversiones en tierra obliga a la introducción de restricciones adicionales en el modelo original. En este trabajo construimos carteras de inversión de tierra en España y estudiamos las modificaciones a introducir en el modelo Sharpe, asimismo las carteras eficientes generadas por cada modelo propuesto son comparadas...There are numerous stock market and real estate applications of Sharpe’s portfolio selection model. This model has been either used to activities planning in risk environment, specially in crops planning in Spain. The application to farmland portfolio selection in Spain becomes feasible due to the improvement of the information about the farmland market. The detection of high levels of correlation in farmland returns forces to the introduction of additional constraints in the original model. In this work farmland portfolios are built, modifications to introduce in the model are studied and the efficient frontiers generated by each proposed model are compared.

We show this generalized formalism is able to: a) supply the essential requirements necessary to establish a connection between classical and quantum formulations of a given system (continuity of labeling, resolution of unity, temporal stability, and action identity); b) reproduce results already known for shape-invariant systems, like harmonic oscillator, double anharmonic, Poschl-Teller and self-similar potentials and; c) point to a formalism that provides an unified description of the different kind of coherent states for quantum systems.

Prospects for IXPE and eXTP polarimetric archaeology of the reflection nebulae in the Galactic center

description: The X-ray polarization properties of the reflection nebulae in the Galactic center inform us about the direction of the illuminating source (through the polarization angle) and the cloud position along the line of sight (through the polarization degree). However, the detected polarization degree is expected to be lowered because the polarized emission of the clouds is mixed with the unpolarized diffuse emission that permeates the Galactic center region. In a real observation, also the morphological smearing of the source due to the point spread function and the unpolarized instrumental background contribute in diluting the polarization degree. So far, these effects have never been included in the estimation of the dilution. We evaluate the detectability of the X-ray polarization predicted for the MC2, Bridge-B2, G0.11-0.11, Sgr B2, Sgr C1, Sgr C2, and Sgr C3 molecular clouds with modern X-ray imaging polarimeters such as the Imaging X-ray Polarimetry Explorer (IXPE) and the Enhanced X-ray Timing and Polarimetry mission (eXTP). We perform realistic simulations of X-ray polarimetric observations considering (with the aid of Chandra maps and spectra) the spatial, spectral, and polarization properties of all the diffuse emission and background components in each region of interest. We find that in the 4.0-8.0 keV band, where the emission of the molecular clouds outshines the other components, the dilution of the polarization degree, including the contribution due to the morphological smearing of the source, ranges between $\sim$19\% and $\sim$55\%. We conclude that for some distance values reported in the literature, the diluted polarization degree of G0.11-0.11, Sgr B2, Bridge-B2, Bridge-E, Sgr C1, and Sgr C3 may be detectable in a 2 Ms long IXPE observations. The enhanced capabilities of eXTP may allow detecting the 4.0-8.0 keV of all the targets considered here.

In particular, by means of a meson-cloud model we investigate the role of nonperturbative antiquark degrees of freedom and the valence quark contribution. A QCD evolution of the obtained GPDs is used to add perturbative effects and to investigate the GPDs' sensitivity to the nonperturbative ingredients of the calculation at larger (experimental) scale.

The modulation of androgen action in prostate cancer by exogenous chemicals, efflux transporter P-glycoprotein and Y-box binding protein-1
Creators: name: Fedoruk, Matthew Nicholas
Publisher: name: University of British Columbia
Year: 2010

description: Prostate cancer is the most frequently diagnosed malignancy and the second leading cause of cancer deaths in Canada. Human prostate carcinomas are often androgen-dependent and respond to androgen withdrawal therapy by temporary regression, followed by androgen- .independent recurrence. These well-established features of prostate cancer strongly suggest that androgens play a major role in prostate carcinogenesis. The overall goal of the research described in this thesis is to gain a more comprehensive understanding of the mechanisms modulating androgen action in prostate cancer cells. This focused on the influence of exogenous chemicals, the efflux transporter P-glycoprotein and the multi-functional transcription factor Y-box Binding Protein-1. Epidemiological evidence, based on agricultural occupational exposures, instigated experimental work that showed pesticides have the potential to mimic or antagonize hormone action, in many cases through androgen receptor binding and interfering with transcriptional activity, thus are capable of disrupting the male hormone-signaling pathway. Furthermore, in prostate cancer cells, androgen responsiveness is modulated by Pgp activity and expression. The biological consequences of increased Pgp expression are decreased androgen accumulation and a corresponding decrease in androgen-regulated transcriptional activity and prostate-specific antigen gene expression. Experimental evidence further supports the hypothesis that early in prostate cancer progression, increased YB-1 expression increases Pgp activity, which consequently lowers androgen levels in prostate tumour cells. Suppression of androgen levels may activate cell survival pathways and lead to an adaptive survival advantage of androgen-independent prostate cancer cells following androgen ablation therapy. Understanding the complex molecular mechanisms by which prostate cancer cells can control androgen function, and how prostate cancer cells evade apoptotic death, provides a paradigm to explain the relationship between androgen action and chemotherapeutic resistance. As a result, the final objective investigated the effects of YB-1 knockdown using antisense oligonucleotides in vitro, and in vivo after androgen withdrawal in human LNCaP prostate cancer tumour xenografts, with the aim of suppressing cellular proliferation and increasing chemosensitivity. Intratumoral injection of 2'-0-(methoxy)ethyl ribose-modified YB-1 ASO and paclitaxel incorporated into a biodegradable, controlled-release formulation in castrated mice delayed Al progression. These results suggest that YB-1 may be a promising target for the treatment of prostate cancer based on a strategy of inhibiting cellular proliferation. Our understanding of the molecular links between androgen action, tumorigenesis, apoptosis, and drug resistance provides the foundation for a new era of targeted cancer therapy.

description: We study experimentally the interaction of nonlinear internal waves in a stratified fluid confined in a trapezoidal tank. The set-up has been designed to produce internal wave turbulence from monochromatic and polychromatic forcing through three processes. The first is a linear transfer in wavelength obtained by wave reflection on inclined slopes, leading to an internal wave attractor which has a broad wavenumber spectrum. Second is the broad banded time-frequency spectrum of the trapezoidal geometry, as shown by the impulse response of the system. The third one is a nonlinear transfer in frequencies and wavevectors via triadic interactions, which results at large forcing amplitudes in a power law decay of the wavenumber power spectrum. This first experimental spectrum of internal wave turbulence displays a $k^{-3}$ behavior.

Using Video Game Development to Motivate Program Design and Algebra Among Inner-City High School Students

description: Introducing inner-city high school students to program design presents unique challenges. The typical assumptions of an introductory programming course, like students understand what variables and functions are, may not be safe. Therefore, asking students to define functions as part of the program design process may be an overwhelming task. Many students do not understand that a function is an abstraction over similar expressions and that parameters represent the differences among these expressions. This articles presents a novel approach to teaching program design to high school students while simultaneously reinforcing high school algebra. The approach is based on a design recipe to help students develop the abstractions that lead to functions. Using a bottom-up approach, students are taught how to abstract over similar expressions. They are then taught how to use high school algebra concepts, like compound functions and function composition, to also design functions. In addition, the article also presents empirical data collected from students to measure their reaction to the course. For the students in the course, the empirical data suggests that high school algebra concepts are successfully reinforced and that students feel they become better problem solvers, find programming intellectually stimulating, and walk away with an interest in programming.

description: Hybrid systems are characterized by the hybrid evolution of their state: A part of the state changes discretely, the other part changes continuously over time. Typically, modern control applications belong to this class of systems, where a digital controller interacts with a physical environment. In this article we illustrate how a combination of the formal method VDM and the computer algebra system Mathematica can be used to model and simulate both aspects: the control logic and the physics involved. A new Mathematica package emulating VDM-SL has been developed that allows the integration of differential equation systems into formal specifications. The SAFER example from Kelly (1997) serves to demonstrate the new simulation capabilities Mathematica adds: After the thruster selection process, the astronaut's actual position and velocity is calculated by numerically solving Euler's and Newton's equations for rotation and translation. Furthermore, interactive validation is supported by a graphical user interface and data animation.

description: This paper presents an automatic method for data classification in nuclear physics experiments based on evolutionary computing and vector quantization. The major novelties of our approach are the fully automatic mechanism and the use of analytical models to provide physics constraints, yielding to a fast and physically reliable classification with nearly-zero human supervision. Our method is successfully validated by using experimental data produced by stacks of semiconducting detectors. The resulting classification is highly satisfactory for all explored cases and is particularly robust to noise. The algorithm is suitable to be integrated in the online and offline analysis programs of existing large complexity detection arrays for the study of nucleus-nucleus collisions at low and intermediate energies.

description: The periodic Floer homology of a surface symplectomorphism, defined by the first author and M. Thaddeus, is the homology of a chain complex which is generated by certain unions of periodic orbits, and whose differential counts certain embedded pseudoholomorphic curves in R cross the mapping torus. It is conjectured to recover the Seiberg-Witten Floer homology of the mapping torus for most spin-c structures, and is related to a variant of contact homology. In this paper we compute the periodic Floer homology of some Dehn twists.

description: Current observations seem to mildly favor an evolving dark energy with the equation of state getting across -1. This form of dark energy, dubbed Quintom, is studied phenomenologically in this paper with an oscillating equation of state. We find oscillating Quintom can unify the early inflation and current acceleration of the universe, leading to oscillations of the Hubble constant and a recurring universe. Our oscillating Quintom would not lead to a big crunch nor big rip. The scale factor keeps increasing from one period to another and leads naturally to a highly flat universe. The universe in this model recurs itself and we are only staying among one of the epochs, in which sense the coincidence problem is reconciled.

description: The Standard Model predictions for $Wγ$ and $Zγ$ production are tested using an integrated luminosity of 200 pb$^{-1}$ of \ppbar collision data collected at the Collider Detector at Fermilab. The cross sections are measured selecting leptonic decays of the $W$ and $Z$ bosons, and photons with transverse energy $E_T>7$ GeV that are well separated from leptons. The production cross sections and kinematic distributions for the $Wγ$ and $Zγ$ are compared to SM predictions.

description: We develop a method of analyzing radio frequency spectral line observations to derive data on the temperature, density, velocity, and molecular abundance of the emitting gas. The method incorporates a radiative transfer code with a new technique for handling overlapping hyperfine emission lines within the accelerated lambda iteration algorithm and a heuristic search algorithm based on simulated annnealing. We apply this method to new observations of N_2H^+ in three Lynds clouds thought to be starless cores in the first stages of star formation and determine their density structure. A comparison of the gas densities derived from the molecular line emission and the millimeter dust emission suggests that the required dust mass opacity is about kappa_{1.3mm}=0.04 cm^2/g, consistent with models of dust grains that have opacities enhanced by ice mantles and fluffy aggregrates.

description: The international planetary science community met in London in January 2020, united in the goal of realising the first dedicated robotic mission to the distant Ice Giants, Uranus and Neptune, as the only major class of Solar System planet yet to be comprehensively explored. Ice-Giant-sized worlds appear to be a common outcome of the planet formation process, and pose unique and extreme tests of our understanding of planetary origins, exotic water-rich planetary interiors, dynamic seasonal atmospheres, complex magnetospheric configurations, geologically-rich icy satellites (both natural and captured), and delicate planetary rings. This article introduces a special issue of Philosophical Transactions of the Royal Society A on Ice Giant System exploration at the start of the 2020s. We review the scientific potential and existing mission design concepts for an ambitious international partnership for exploring Uranus and/or Neptune in the coming decades.

description: We investigate the role of noise in the phenomenon of stochastic synchronization of switching events in a rocked, overdamped bistable potential driven by white Gaussian noise, the archetype description of Stochastic Resonance. We present a new approach to the stochastic counting process of noise-induced switching events: starting from the Markovian dynamics of the nonstationary, continuous particle dynamics one finds upon contraction onto two states a non-Markovian renewal dynamics. The output frequency is determined as the velocity of the underlying discrete phase dynamics. The phenomenon of noise-assisted phase synchronization is investigated in terms of an effective, instantaneous phase diffusion. The theory is applied to rectangular-shaped rocking signals versus increasing input-noise strengths. Precise numerical simulations corroborate very favorably our analytical results. The novel theoretical findings are also compared with prior findings.
