Year: 2018

description: La Jetée (1962) is a Chris Marker movie composed by still images, photographs, with the exception of a very short sequence. The paper aims to account for the experience of temporality induced by photography, framing the structural analysis of the movie in a phenomenological horizon, in particular with regard to the Husserlian’s notion of “Living Present”.

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Maxwell refrigerator as a device that can transfer heat from a cold to hot temperature reservoir making use of information reservoir was introduced by Mandal et al. \cite{Mandal2013a}. The model has a two state demon and a bit stream interacting with two thermal reservoirs simultaneously. We work out a simpler version of the refrigerator where the demon and bit system interact with the reservoirs separately and for a duration long enough to establish equilibrium. The efficiency, $η$, of the device when working as an engine as well as the coefficient of performance (COP) when working as a refrigerator are calculated. It is shown that the maximum efficiency matches that of a Carnot engine/refrigerator working between the same temperatures, as expected. The COP at maximum power decreases as $\frac{1}{T_h}$ when $T_h >T_c \gg ΔE$ ($k_B = 1$), where $T_h$ and $T_c$ are the temperatures of the hot and cold reservoirs respectively and $ΔE$ is the level spacing of the demon. $η$ at maximum power of the device, when working as a heat engine, is found to be $\frac{T_h}{0.779 + T_h}$ when $T_c \ll ΔE$ and $T_h \gg ΔE$.

Sparks of reality: on the temporalities of the photographic image
Creators: name: Conceição, Nélio
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2018

description: Within the context of the contemporary heterogeneity of photographic practices, the present text describes some of the possibilities of understanding the temporality of photographs, giving an account of some important theoretical references (Benjamin, Kracauer, Barthes, Derrida). Bearing this in mind, describing photographs as sparks of reality is a way of expanding the Benjaminian proposal and avoiding the strict logics of causality. The strength of photography unfolds the technologically rooted paradox of photographs, whose contemporary relevance can be analysed in the intersection between aesthetics, history and politics. The film 48, by the Portuguese filmmaker Susana Sousa Dias, explores this intersection by using and showing the cracks of the political prisoners’ mug shots.

The field theory is $\mathcal{N} =1$ supersymmetric $\prod U(N_{ij})$ Yang-Mills gauge theory. Strong coupling effects are analyzed in the deformed geometry. We propose open-closed string duality via a geometric transition in toric geometry. The T-dual type IIA picture and M-theory lifting are also considered.

description: There is a known generalization of the classical Schwarz lemma to holomorphic functions from the polydisk to the disk. In this paper, we characterize those functions which satisfy equality everywhere in this generalized inequality: they are the transfer function of an n+1 by n+1 symmetric unitary, and in particular, are rational, inner, and belong to the Schur-Agler class of the polydisk. We also present some sufficient conditions for a function to be of this type.

description: We observed spin-wave transmission through an air gap that works as a prohibited region. The spin waves were excited by circularly polarized pump pulses via the inverse Faraday effect, and their spatial propagation was detected through the Faraday effect of probe pulses using a pump-probe imaging technique. The experimentally observed spin-wave transmission was reproduced using numerical calculations with a Green's function method and micromagnetic simulation. We found that the amplitude of the spin waves decays exponentially in the air gap, which indicates the existence of evanescent spin waves in the magnetic dipole regime. This finding will pave the way for controllable amplitudes and phases of spin waves propagating through an artificial magnonic crystal.

description: We report on the application of a dynamic decoherence control pulse sequence on a nuclear quadrupole transition in $Pr^{3+}:Y_2SiO_5$ . Process tomography is used to analyse the effect of the pulse sequence. The pulse sequence was found to increase the decoherence time of the transition to over 30 seconds. Although the decoherence time was significantly increased, the population terms were found to rapidly decay on the application of the pulse sequence. The increase of this decay rate is attributed to inhomogeneity in the ensemble. Methods to circumvent this limit are discussed.

description: The aims of the present paper is to analyse the specific visual regime of some never-before-exhibited photographs displayed at the photographic exhibition organised for the 60th anniversary of the Liberation of Mauthausen camp in 2005. I will proceed accordingly to a three steps process. First of all, I will try to show how photographs can be considered as a form of writing, namely a “light writing”. I will then provide a general overview of the catalogue of the exhibition but through a decomposition and reassembly of the photographic images, trying to work for a decentralization of the gaze beyond the documentary value of these photographs. Finally, I will draw some conclusions, proposing further reflections on photography as “trace” and “supplement” of the visible.

description: In this letter, we study the scattering of spin-$\frac{1}{2}$ particles from a spin-independent parity time ($\cal PT$)-symmetric complex potential, and for the first time, theoretically demonstrate the coexistence of $\cal PT$-symmetric and $\cal PT$-broken phases for broadband energy spectra in this system. We also show the existence of anisotropic transmission resonances, accessible through the tuning of energy. Our results are promising for applications in spintronics, semiconductor-based devices, and a better understanding of the topological surface states.

We show that: (i) The Cuntz semigroup W(A) of equivalence classes of positive elements in matrix algebras over A is weakly unperforated. (ii) If A is exact, then A is purely infinite if and only if A is traceless. (iii) If A is separable and nuclear, then A is isomorphic to A tensor O_infty if and only if A is traceless. (iv) If A is simple and unital, then the stable rank of A is one if and only if A is finite. We also characterise when A is of real rank zero.

description: We investigate whether the hard X-ray photon index ($Γ$) versus accretion rate correlation for super-Eddington accreting quasars is different from that for sub-Eddington accreting quasars. We construct a sample of 113 bright quasars from the Sloan Digital Sky Survey Data Release 14 quasar catalog, including 38 quasars as the super-Eddington subsample and 75 quasars as the sub-Eddington subsample. We derive black-hole masses using a simple-epoch virial mass formula based on the ${\rm Hβ}$ lines, and we use the standard thin disk model to derive the dimensionless accretion rates ($\dot{\mathscr{M}}$) for our sample. The X-ray data for these quasars are collected from the Chandra and XMM-Newton archives. We fit the hard X-ray spectra using a single power-law model to obtain $Γ$ values. We find a statistically significant ($R_{\rm S}=0.43$, $p=7.75\times{10}^{-3}$) correlation between $Γ$ and $\dot{\mathscr{M}}$ for the super-Eddington subsample. The $Γ$-$\dot{\mathscr{M}}$ correlation for the sub-Eddington subsample is also significant, but weaker ($R_{\rm S}=0.30$, $p=9.98\times{10}^{-3}$). Linear regression analysis shows that ${\rm Γ}=(0.34\pm0.11){\rm log}{\dot{\mathscr{M}}}+(1.71\pm0.17)$ and ${\rm Γ}=(0.09\pm0.04){\rm log}{\dot{\mathscr{M}}}+(1.93\pm0.04)$ for the super- and sub-Eddington subsamples, respectively. The $Γ$-$\dot{\mathscr{M}}$ correlations of the two subsamples are different, suggesting different disk-corona connections in these two types of systems. We propose one qualitative explanation of the steeper $Γ$-$\dot{\mathscr{M}}$ correlation in the super-Eddington regime that involves larger seed photon fluxes received by the compact coronae from the thick disks in super-Eddington accreting quasars.

L’esperienza per immagini: condizionamento e possibilità dello sguardo fotografico nella percezione dell’arte
Creators: name: Laskaris, Caterina Zaira
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2018

description: Our society is experiencing a radical transformation through photographic multimedia. The photographic gaze is the dominant mode of the daily visual relationship with reality, due to the extreme pervasiveness of photography in every field of our experience. Starting from some empirical considerations, this paper will reflect on this trend in terms of visual perception of reality in general, focusing on works of art. Since visual art is made to be perceived as an object, this field of experience is congenial to examine the implications of the capillary multimedia conveyance in our perceptive dependence on photographic images. The consequences are significant both in the historical-artistic methodology and in the education of the gaze applied to art, especially for the younger generations. The transformation in progress should not, however, be interpreted in negative terms, nor as an obstacle to the understanding of the world, but as a terrain of shared experience, on which to work with more conscious instruments.

Photographing Sculpture: Aesthetic and Semiotic Issues
Creators: name: Polacci, Francesca
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2018

description: The essay aims to outline an epistemology of photography through the critical issues that arise from the encounter between photography and sculpture. In particular, it investigates the aesthetic and semiotic constraints that define the specificity of the photographic look with respect to a sculptural three-dimensional vision. The relationship between documentary and art photographs is the main area of research; specifically, the essay tries to highlight the interpretative value that can also be attributed to documentary photography, underlining the boundaries of a complex distinction. A specific section is devoted to Medardo Rosso’s photographs of his own sculptures. Rosso’s work solicits a reflection on the status of photography and on some theoretical problems such as reproducibility, the relationship between original and copy, and the creative gap produced by variation in a series. The artist suggests a peculiar “grammar” of photography by virtue of his relationship with another art – sculpture.

description: The conditions for the formation of zero-energy peak in the density of states (DOS) in the normal metal / insulator / diffusive ferromagnet / insulator / s-wave superconductor (N/I/DF/I/S) junctions are studied by solving the Usadel equations. The DOS of the DF is calculated in various regimes for different magnitudes of the resistance, Thouless energy and the exchange field of the DF, as well as for various resistances of the insulating barriers. The conditions for the DOS peak are formulated for the cases of weak proximity effect (large resistance of the DF/S interface) and strong proximity effect (small resistance of the DF/S interface).

description: The study of extragalactic planetary nebulae (EPN) is a rapidly expanding field. The advent of powerful new instrumentation such as the PN spectrograph has led to an avalanche of new EPN discoveries both within and between galaxies. We now have thousands of EPN detections in a heterogeneous selection of nearby galaxies and their local environments, dwarfing the combined galactic detection efforts of the last century. Key scientific motivations driving this rapid growth in EPN research and discovery have been the use of the PNLF as a standard candle, as dynamical tracers of their host galaxies and dark matter and as probes of Galactic evolution. This is coupled with the basic utility of PN as laboratories of nebula physics and the consequent comparison with theory where population differences, abundance variations and star formation history within and between stellar systems informs both stellar and galactic evolution. Here we pose some of the burning questions, discuss some of the observational challenges and outline some of the future prospects of this exciting, relatively new, research area as we strive to go fainter, image finer, see further and survey faster than ever before and over a wider wavelength regime

Léal souvenir? La photographie, la peinture et le serment de l’image fidèle

Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2018

description: The aim of this paper is to question the objectivist conception of photography by confronting it with the history – and epistemology – of the painted image. I suggest that the idea of photography as an objective testimony seems to rest upon a phenomenon already described by ancient rhetoric – enargeia, which Cicero latinized into evidentia. Thus the question is raised whether the objectivity of the photographic image is not the mere continuation of an old rhetorical and pictorial tradition about the epistemic-rhetoric evidentia of testimony. Moreover, through the detailed analysis of two paintings by Jan Van Eyck – The Arnolfini Portrait and Léal Souvenir –, I argue that what guarantees an image’s objectivity to the point of its being accepted as evidence ultimately is not the non-subjective mechanical process or the automatic indexical device used to make the photographic image but the image’s built-in pledge of faithfulness which was at the heart of painters’ thoughts long before the invention of photography.

description: Accurate atomic data is an essential ingredient for the calculation of reliable non-local thermodynamic equilibrium (NLTE) model atmospheres that are mandatory for the spectral analysis of hot stars. We aim to search for and identify for the first time spectral lines of copper (atomic number Z = 29) and indium (Z = 49) in hot white dwarf (WD) stars and to subsequently determine their photospheric abundances. Oscillator strengths of Cu IV - VII were calculated to include radiative and collisional bound-bound transitions of Cu in our NLTE model-atmosphere calculations. Oscillator strengths of In IV - VI were compiled from the literature. We newly identified 1 Cu IV, 51 Cu V, 2 Cu VI, and 5 In Vlines in the ultraviolet (UV) spectrum of DO-type WD RE 0503-289. We determined the photospheric abundances of 9.3 X 10**-5 (mass fraction, 132 times solar) and 3.0 X 10**-5 (56 600 times solar), respectively; we also found Cu overabundances in the DA-type WD G191-B2B (6.3 X 10**-6, 9 times solar). All identified Cu IV - VI lines in the UV spectrum of RE 0503-289 were simultaneously well reproduced with our newly calculated oscillator strengths. With the detection of Cu and In in RE 0503-289, the total number of trans-iron elements (Z > 28) in this extraordinary WD reaches an unprecedented number of 18.

description: The fundamental mode of rotation in quantum fluids is given by a vortex, whose quantized value yields the orbital angular momentum (OAM) per particle. If the vortex is displaced (off-centered) from the reference point for rotation, the angular momentum is reduced and becomes fractional. Such displaced vortices can further exhibit a peculiar dynamics in presence of confining potentials or couplings to other fields. We study analytically a number of 2D systems where displaced vortices exhibit a noteworthy dynamics, including time-varying self-sustained oscillation of the OAM, complex reshaping of their morphology with possible creation of vortex-antivortex pairs and peculiar trajectories for the vortex core with sequences of strong accelerations and decelerations which can even send the core to infinity and bring it back. Interestingly, these do not have to occur conjointly, with complex time dynamics of the vortex core and/or their wavepacket morphology possibly taking place without affecting the total OAM. Our results generalize to simple and fundamental systems a phenomenology recently reported with Rabi-coupled bosonic fields, showing their wider relevance and opening prospects for new types of control and structuring of the angular momentum of light and/or quantum fluids.

The gauge choice can significantly affect the overall accuracy of the evolution. It is possible to reconcile certain gauge dependent discrepancies by examining the convergence limit. We illustrate these results using an initial data set recently evolved by Bruegmann (Phys. Rev. Lett. 92, 211101). For our highest resolution and most accurate gauge, we estimate the duration of this data set's last orbit to be approximately $59 M_{ADM}$.

description: Climate change is a natural and dynamic phenomenon resulting from complex interrelationships between physical, environmental and human factors. The sustainability of life on earth depends partly on the ability of mankind to maintain this natural and balanced flow of such gases such as carbon dioxide (CO2) and water vapor traping heat. Unfortunately, human beings contribute significantly to the presence of such gases known as Green House Gases (GHGs) through agricultural and industrial activities. The implications are the excess trap of sunlight and the blocking of outward radiation. In sub-Saharan Africa (SSA), the importance of agriculture cannot be stressed enough given that it is central to economic growth and most of economic activities in the region is still dependent on agricultural expansion. The crux of the matter is that, in Africa, the bulk of agricultural output is still produced by smallholder farmers who unfortunately continue to depend on climate variability. Hence understanding the relationships between climate variability and agricultural production is therefore critical to SSA countries. Unfortunately, the statistics base on climate change is currently very poor and the provision of these statistics is compelling and will contribute significantly to the understanding of the impacts of these changes to agriculture, our livelihoods and economic development. Recent and upcoming events witness these concerns. This paper attempts to provide a theoretical and empirical framework for exploring the magnitude of climate variability in the explanation of agricultural production in Sub- Saharan Africa. Despite the statistics constraints, it is expected that the design and testing of theoretical model on climate change will not only attract interests in investing in climate changes statistics but also provide better understanding of the relationships between individual and aggregate crop production performances and insights for policies directions as pertaining to SSA countries.

description: A changing world of increasing complexity, fluctuating prices, high energy costs and limited data necessitate creative blending of economic theory and available empirical statistics to understand the welfare impacts in a specific market. In this paper, a programming approach is used in tandem with spatial economic theory to understand the spatial welfare impacts of an ethanol plant established in an area with a beef feeding industry. The study concludes that corn transportation costs are less significant in plant pricing strategy than originally identified by other studies. Local ethanol plant competition is found to explain the lower-than-feed value pricing of ethanol byproducts at the plant. In the study, average welfare effects are calculated for the ethanol plant, corn producers and beef producers under different market situations and changes.

description: In this paper we inquire why after more than 25 years of domestic agricultural reforms in Mexico and 15 years of trade liberalization of maize under NAFTA –a non-competitive crop and the major staple in Mexico–domestic production of this field crop has increased. We present new empirical evidence showing that, as expected, maize prices in Mexico dropped until 2006 and have experienced a process of convergence with USA prices, and maize imports from the USA increased. However, despite lower prices, maize production in Mexico rose and has experienced a positive structural change since 1992, two years before the beginning of NAFTA’s implementation. Based on the heterogeneity of maize production in Mexico, three possible explanations are proposed to explain this unexpected outcome: government supports to big commercial farmers in the agriculturally rich North of Mexico; the persistence of maize production by subsistence farmers; and to a lesser degree, increasing yields on some irrigated maize farms. We finish the paper by drawing lessons from the experience of Mexico for other Less Developed Countries.

description: Consumers' willingness to pay for food products decreases when the food label indicates that a food product is produced with the aid of modern biotechnology. This bulletin presents empirical evidence on consumers' willingness to pay for biotech foods based on the presence or absence of labels advising that the food was prepared with the aid of biotechnology. The authors designed and conducted an experimental auction to elicit consumers' willingness to pay for "genetically modified" (GM)-labeled and standard-labeled foods under different information regimes. The evidence gathered for vegetable oil, tortilla chips, and potatoes shows that labels matter. In particular, under all information treatments, consumers discounted food items labeled "GM" by an average of 14 percent. While gender, income, and other demographic characteristics appeared to have only a slight impact on consumers' willingness to pay for biotech foods, information from interested parties and third-party (independent) sources was found to have a strong impact.

description: Background: Natural or quasi experiments are appealing for public health research because they enable the evaluation of events or interventions that are difficult or impossible to manipulate experimentally, such as many policy and health system reforms. However, there remains ambiguity in the literature about their definition and how they differ from randomised controlled experiments and from other observational designs. Methods: We conceptualise natural experiments in in the context of public health evaluations, align the study design to the Target Trial Framework, and provide recommendation for improvement of their design and reporting. Results: Natural experiment studies combine features of experiments and non-experiments. They differ from RCTs in that exposure allocation is not controlled by researchers while they differ from other observational designs in that they evaluate the impact of event or exposure changes. As a result they are, in theory, less susceptible to bias than other observational study designs. Importantly, the strength of causal inferences relies on the plausibility that the exposure allocation can be considered "as-if randomised". The target trial framework provides a systematic basis for assessing the plausibility of such claims, and enables a structured method for assessing other design elements. Conclusions: Natural experiment studies should be considered a distinct study design rather than a set of tools for analyses of non-randomised interventions. Alignment of natural experiments to the Target Trial framework will clarify the strength of evidence underpinning claims about the effectiveness of public health interventions.

Re/defining gender and sex : subtitle educating for trans, transsexual, and intersex access and inclusion to sexual assault centres and transition houses
Creators: name: White, Caroline
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines the work of sexual assault centres, transition houses, community educators and activists, in educating for trans, transsexual, and intersex access to sexual assault centres and transition houses. Results of a questionnaire sent to 104 sexual assault centres and transition houses in British Columbia revealed that 45 of the 62 organizations that responded identified as being accessible to transgendered women, clearly refuting the popular perception that the majority of sexual assault centres and transition houses are inaccessible. Interviews with eleven educators and activists showed that trans, transsexual, and intersex education in sexual assault centres and transition houses was generally divided into three distinct areas: "Trans" 101, which provides the foundation for all subsequent education; the development of policy; and anti-violence education. The educators and activists identified various trends in their work including: the conflation of all trans, transsexual, and intersex identities under the rubric "trans"; and the privileging of gender over sex variances, male-to-female (MTF) identities over all others, and gender over all other forms of identity, including race, class, sexuality and ability. Some educators and activists argued that the degree to which some identities are privileged over others, is the degree to which "trans" will continue to be perceived as synonymous with white, middle-class, straight and able-bodied MTF transsexuals, and the degree to which all other identities and related issues will be rendered (in)visible. Educators and activists also examined the relationship between opposition to trans, transsexual, and intersex access and inclusion to sexual assault centres and transition houses, and dominant feminism's continued privileging of sex and gender over all other analyses such as race, class, heterosexism, and ableism.
Synthesis of Parallel Synchronous Software

description: In typical embedded applications, the precise execution time of the program does not matter, and it is sufficient to meet a real-time deadline. However, modern applications in information security have become much more time-sensitive, due to the risk of timing side-channel leakage. The timing of such programs needs to be data-independent and precise. We describe a parallel synchronous software model, which executes as N parallel threads on a processor with word-length N. Each thread is a single-bit synchronous machine with precise, contention-free timing, while each of the N threads still executes as an independent machine. The resulting software supports fine-grained parallel execution. In contrast to earlier work to obtain precise and repeatable timing in software, our solution does not require modifications to the processor architecture nor specialized instruction scheduling techniques. In addition, all threads run in parallel and without contention, which eliminates the problem of thread scheduling. We use hardware (HDL) semantics to describe a thread as a single-bit synchronous machine. Using logic synthesis and code generation, we derive a parallel synchronous implementation of this design. We illustrate the synchronous parallel programming model with practical examples from cryptography and other applications with precise timing requirements.

Photographic agents. Jorge Molder: detective, magician, actor.

description: The œuvreof Portuguese photographer Jorge Molder (Lisbon, 1947) can be construed as a series of series. These series are filled with a wealth of absent presences, of possibilities that arise and fade without ever reaching actualization or confirmation, thereby contributing to create a ‘detective-story’ atmosphere. This also proves to be true as regards Molder’s own body. Indeed, his face, his hands are recurrent “subjects” running through his 40 years of work. Even so, when we ask who the man is that we see in Molder’s series, the answer is problematic. On the one hand, we know it is “him”, insofar as he himself is the model for his iconic “constructions”. On the other hand, Molder’s images are not “self-portraits” aiming to reveal the essence of his self, but rather “self-representations” creating a peculiar “character” who is and yet is not him: a double.

description: The (parallel) linear transports along paths in vector bundles are axiomatically described. Their general form and certain properties are found. It is shown that these transports are locally (i.e. along every fixed path) always Euclidean ones in a senses that there exist frames in which their matrices are unit. The investigated transports along paths are described in terms of their local coefficients, as well as in terms of derivations along paths.

description: This report examines the economic effects of the principal programs authorized under the Farm Security and Rural Investment Act of 2002 that influence the U.S. dairy sector. The analytical results presented in this study were used as input to a broader study mandated by Congress, which required an evaluation of the economic impacts of Federal milk marketing orders, direct payments to producers, price supports, and export programs. This study examines the effects of dairy policies on prices, program payments, and other variables under different scenarios. The results are compared to a baseline set of estimates over the 2002-07 period. The findings show that gross income in the U.S. dairy sector would be $7.2 billion below baseline levels over the course of this period if the programs were discontinued. Over the same period, cumulative Government outlays for these programs would be approximately $5.5 billion below baseline levels.
