The Spectral Content of SDO/AIA 1600 and 1700 Å Filters from Flare and Plage Observations
Authors: Simões Paulo J. A. , Reid Hamish A. S. , Milligan Ryan O. , Fletcher Lyndsay 
Published: January 2019

Abstract
The strong enhancement of the ultraviolet emission during solar flares is usually taken as an indication of plasma heating in the lower solar atmosphere caused by the deposition of the energy released during these events. Images taken with broadband ultraviolet filters by the Transition Region and Coronal Explorer and Atmospheric Imaging Assembly (AIA; 1600 and 1700 Å) have revealed the morphology and evolution of flare ribbons in great detail. However, the spectral content of these images is still largely unknown. Without knowledge of the spectral contribution to these UV filters, the use of these rich imaging data sets is severely limited. Aiming to solve this issue, we estimate the spectral contributions of the AIA UV flare and plage images using high-resolution spectra in the range 1300–1900 Å from the Skylab NRL SO82B spectrograph. We find that the flare excess emission in AIA 1600 Å is dominated by the C iv 1550 Å doublet (26%), Si i continua (20%), with smaller contributions from many other chromospheric lines such as C i 1561 and 1656 Å multiplets, He ii 1640 Å, and Si ii 1526 and 1533 Å. For the AIA 1700 Å band, the C i 1656 Å multiplet is the main contributor (38%), followed by He ii 1640 (17%), and accompanied by a multitude of other, weaker chromospheric lines, with minimal contribution from the continuum. Our results can be generalized to state that the AIA UV flare excess emission is of chromospheric origin, while plage emission is dominated by photospheric continuum emission in both channels.
L1 Stream Deflection and Ballistic Launching at the Disk Bow Shock: An Absorption-line Velocity Analysis in Semi-detached Binaries
Authors: Godon Patrick 
Published: January 2019

Abstract
Observations of semi-detached interacting binaries reveal orbital modulation in the optical, UV, and X-ray bands, indicating the presence of absorbing material obscuring the disk and accreting primary star at specific orbital phases consistent with L1 stream material overflowing the disk edge. We simulate the L1 stream interaction with the disk using tests particles within the context of the Roche model in the restricted three-body problem. At the disk bow shock the L1 stream particles are deflected and launched onto ballistic trajectories above the disk (as would normally occurs at the front of a detached shock in the hypersonic flow past a blunt body). At a given scale height, the material is assumed to continue without being affected by the disk, while at lower altitude it is being launched at an increasing elevation, as well as gradually being dragged by the Keplerian flow. Near the disk midplane (z ≪ H) the material is assumed to become part of the disk. We follow the stream material ballistic trajectories over the disk surface, where they reach a maximum height z/r at a binary phase Φ ∼ 0.75 and land on the disk at a smaller radius around phase Φ ∼ 0.5. The phase of the maximum height, the phase of the landing site, and the phase of the hot spot itself, all decrease significantly with decreasing radius. The radial velocity for each L1 stream ballistic trajectory along the line of sight (of the observer) to the hot inner parts of the disk is computed as a function of the orbital phase for a binary configuration matching the dwarf nova U Geminorum. The computed velocity amplitudes, phases, and pattern match the observed velocity offsets of the metal lines in the FUSE spectrum of U Gem during outburst. As ballistic trajectories are much easier to compute than realistic 3D hydrodynamical simulations, we propose the use of the L1 stream deflection and ballistic launching as a way to analyze the absorption-line orbital variability in semi-detached binaries and to assess or confirm, with some limitations, system parameters such as the mass ratio, inclination, and disk outer radius.

Published: January 2019

Abstract
We present cosmological parameter measurements from the Deep Lens Survey (DLS) using galaxy–mass and galaxy–galaxy power spectra in the multipole range ℓ = 250–2000. We measure galaxy–galaxy power spectra from two lens bins centered at z ∼ 0.27 and 0.54 and galaxy–mass power spectra by cross-correlating the positions of galaxies in these two lens bins with galaxy shapes in two source bins centered at z ∼ 0.64 and 1.1. We marginalize over a baryonic feedback process using a single-parameter representation and a sum of neutrino masses, as well as photometric redshift and shear calibration systematic uncertainties. For a flat ΛCDM cosmology, we determine

, in good agreement with our previous DLS cosmic shear and the Planck cosmic microwave background (CMB) measurements. Without the baryonic feedback marginalization, S
8 decreases by

because the dark-matter-only power spectrum lacks the suppression at the highest ℓ values owing to active galactic nucleus (AGN) feedback. Together with the Planck CMB measurements, we constrain the baryonic feedback parameter to

, which suggests an interesting possibility that the actual AGN feedback might be stronger than the recipe used in the OverWhelmingly Large cosmological hydrodynamical Simulations. The interpretation is limited by the validity of the baryonic feedback simulation and the one-parameter representation of the effect.
Expected Imprints of the Carousel in Multi-frequency Pulsar Observations and New Evidence for Multi-altitude Emission
Authors: Maan Yogesh 
Published: January 2019

Abstract
Subpulse modulation has been regarded as one of the most insightful and intriguing aspects of pulsar radio emission. This phenomenon is generally explained by the presence of a carousel of sparks in the polar acceleration gap region that rotates around the magnetic axis due to the E × B drift. While there have been extensive single pulse studies, geometric signatures of the underlying carousel, or lack thereof, in simultaneous multi-frequency observations have remained largely unexplored. This work presents a theoretical account of such expected signatures, particularly that of a geometry induced phase-offset in subpulse modulation, including various formulae that can be readily applied to observations. A notable result is a method to resolve aliasing in the measured subpulse modulation period without relying on knowledge of the viewing geometry parameters. It is also shown in detail that the geometry induced phase-offset enables critical tests of various observed phenomena as well as proposed hypotheses, e.g., multi-altitude emission, magnetic field twisting, pseudo-nulls, etc., in addition to that of the carousel model itself. Finally, a detailed analysis of a 327 MHz pulse sequence of PSR B1237+25 is presented as a case study to test the single frequency multi-altitude emission scenario. The analysis provides firm evidence of the inner and outer conal components of this pulsar to have originated from the same carousel of sub-beams and emitted at different heights.

Published: January 2019

Abstract
The density and mass of the spiral galaxy NGC 3198 have been studied as functions of the distance from the center of galaxy depending on its observed rotation curve. Calculation of density and mass at different radii of the galaxy NGC 3198 show that the central inner density ρ1(r) at r < r
t (r
t is the turn-off radius) is found to be constant ρ1 = 0.387 M
o pc−3, while the density ρ2(r) of the outer region r > r
t is much less than the inner region, which varies from 0.0187 M
o pc−3 at r = 4 kpc to 0.00278 M
o pc−3 at r = 30 kpc. On the other hand, the inner mass m1(r) at r < r
t grows from 1.33 × 109
M
o at r = 0.1 kpc to a mass of 8.539 × 109
M
o at r = 4 kpc, while the outer mass m2(r) at r ≥ r
t changes from 8.539 × 109
M
o at the turn-off radius r
t to 5.262 × 1010
M
o at r = 30 kpc of the galaxy. Finally, the behavior of the calculated density and mass is consistent with other works.

Objective.The aim of this study was to describe the prevalence of erectile dysfunction (ED), as well as associated demographic and clinical features, in men with systemic lupus erythematosus (SLE), by means of a systematic, standardized evaluation.Methods.We performed a transversal study in 8 tertiary care centers in Latin America. We included male patients ≥ 16 years who fulfilled ≥ 4 American College of Rheumatology criteria for SLE and had regular sexual activity, and evaluated them with the International Index of Erectile Function-5 questionnaire. Relevant demographic, clinical, and serological characteristics were recorded. We included 2 control groups: the first was made up of healthy men and the second of men with autoimmune diseases other than SLE (non-SLE group).Results.We included 590 subjects (174 SLE, 55 non-SLE, and 361 healthy controls). The prevalence of ED in the SLE group was 69%. Mean age in that group was 36.3 ± 1.03 years. Among SLE patients with and without ED, these factors were significantly different: the presence of persistent lymphopenia (p = 0.006), prednisone dose (9.3 ± 1.2 vs 5.3 ± 1.3 mg, p = 0.026), and the Systemic Lupus International Collaborating Clinics damage score (1.25 ± 0.14 vs 0.8 ± 0.16 points, p = 0.042). Independent risk factors for ED in patients with SLE were persistent lymphopenia (OR 2.79, 95% CI 1.37–5.70, p = 0.001) and corticosteroid use in the previous year (OR 2.15, 95% CI 1.37–3.37, p = 0.001).Conclusion.Regardless of comorbidities, treatment (excluding steroids), and type of disease activity, patients with SLE have a high prevalence of ED, especially considering that most patients are young. Recent corticosteroid use and persistent lymphopenia, which could be related to endothelial dysfunction, are risk factors for this complication in men with SLE.

Objective.In cross-sectional studies, elevated osteopontin (OPN) levels have been proposed to reflect, and/or precede, progressive organ damage and disease severity in systemic lupus erythematosus (SLE). We aimed, in a cohort of patients with recent-onset SLE, to determine whether raised serum OPN levels precede damage and/or are associated with disease activity or certain disease phenotypes.Methods.We included 344 patients from the Systemic Lupus International Collaborating Clinics (SLICC) Inception Cohort who had 5 years of followup data available. All patients fulfilled the 1997 American College of Rheumatology (ACR) criteria. Baseline sera from patients and from age- and sex-matched population-based controls were analyzed for OPN using ELISA. Disease activity and damage were assessed at each annual followup visit using the SLE Disease Activity Index 2000 (SLEDAI-2K) and the SLICC/ACR damage index (SDI), respectively.Results.Compared to controls, baseline OPN was raised 4-fold in SLE cases (p < 0.0001). After relevant adjustments in a binary logistic regression model, OPN levels failed to significantly predict global damage accrual defined as SDI ≥ 1 at 5 years. However, baseline OPN correlated with SLEDAI-2K at enrollment into the cohort (r = 0.27, p < 0.0001), and patients with high disease activity (SLEDAI-2K ≥ 5) had raised serum OPN (p < 0.0001). In addition, higher OPN levels were found in patients with persistent disease activity (p = 0.0006), in cases with renal involvement (p < 0.0001) and impaired estimated glomerular filtration rate (p = 0.01).Conclusion.The performance of OPN to predict development of organ damage was not impressive. However, OPN associated significantly with lupus nephritis and with raised disease activity at enrollment, as well as over time.

Objective.To propose multidisciplinary, consensus-based, standardization of operational terminology and method of assessment for temporomandibular joint (TMJ) involvement in juvenile idiopathic arthritis (JIA).Methods.Using a sequential expert group–defined terminology and methods-of-assessment approach by (1) establishment of task force, (2) item generation, (3) working group consensus, (4) external expert content validity testing, and (5) multidisciplinary group of experts final Delphi survey consensus.Results.Seven standardized operational terms were defined: TMJ arthritis, TMJ involvement, TMJ arthritis management, dentofacial deformity, TMJ deformity, TMJ symptoms, and TMJ dysfunction.Conclusion.Definition of 7 operational standardized terms provides an optimal platform for communication across healthcare providers involved in JIA-TMJ arthritis management.
Opioid Use in Patients with Ankylosing Spondylitis Is Common in the United States: Outcomes of a Retrospective Cohort Study
Authors: Sloan Victor S. , Sheahan Anna , Stark Jeffrey L. , Suruki Robert Y. 
Published: January 2019

Objective.To assess the prevalence of chronic opioid use in patients with ankylosing spondylitis (AS), and to compare the characteristics of patients with and without chronic opioid use.Methods.This was a retrospective cohort study of patients with AS identified in the Truven Health MarketScan Research database between January 1, 2012, and March 31, 2017. Commercial and Medicaid claims data were examined using both specific (720.0 and M45.x) and broader (720.x and M45.x) International Classification of Diseases (ICD) coding definitions. Patients were aged ≥ 18 years on the date of first qualifying ICD code occurrence (the index date). Demographics and clinical characteristics were assessed in the 12-month period preceding the index date. The 12-month followup period was used to assess prevalence and characteristics of chronic opioid use.Results.Chronic opioid use was common among patients with commercial claims (23.5% of ICD 720.0 patients; 27.3% of ICD 720.x patients), and especially those with Medicaid claims (57.1% and 76.7%, respectively). The proportion of patients with claims for anti–tumor necrosis factor therapies during followup was often low, and for Medicaid patients was lower among those with chronic opioid use (29.6% of ICD 720.0 patients; 2.3% of ICD 720.x patients) than those without (47.1% and 7.1%, respectively). Among chronic opioid users in all cohorts, the cumulative supply of opioids was typically high (≥ 270 days in the followup period); most opioids prescribed were Schedule II.Conclusion.Patients with AS receive opioids with disturbing frequency. The infrequent prescription of recommended therapies to these patients reflects a need to optimize treatment further through education of patients and healthcare professionals alike.

Position Statement: A Pragmatic Approach for Medical Cannabis and Patients with Rheumatic Diseases
Authors: Fitzcharles Mary-Ann , Niaki Omid Zahedi , Hauser Winfried , Hazlewood Glen ,   the Canadian Rheumatology Association
Published: January 2019

Objective.Pain is one reason some rheumatology patients may consider use of medical cannabis, a product increasingly perceived as a safe and neglected natural treatment option for many conditions. Legalization of recreational cannabis in Canada will promote access to cannabis. Physicians must therefore provide patients with the best evidence-based information regarding the medicinal effects and harm of cannabis.Methods.The Canadian Rheumatology Association (CRA) mandated the development of a position statement for medical cannabis and the rheumatology patient. The current literature regarding the effects of medical cannabis for rheumatology patients was assessed, and a pragmatic position statement to facilitate patient care was developed by the Therapeutics Committee of the CRA and approved by the CRA board.Results.There are no clinical trials of medical cannabis in rheumatology patients. Evidence is insufficient about the benefit of pharmaceutical cannabinoids in fibromyalgia, osteoarthritis, rheumatoid arthritis, and back pain, but there is evidence of a high risk of harm. Extrapolating from other conditions, medical cannabis may provide some symptom relief for some patients. Short-term risks of psychomotor effects can be anticipated, but longterm risks have not been determined and are of concern.Conclusion.Despite lack of evidence for use of medical cannabis in rheumatology patients, we acknowledge the need to provide empathetic and pragmatic guidance for patient care. This position statement aims to facilitate the dialogue between patients and healthcare professionals in a mutually respectful manner to ensure harm reduction for patients and society.
D’où vient la théorie de l’exploitation de Marx ?
Authors: Le Masne Pierre 
Published: January 2019

Le papier s’interroge sur les origines de la théorie de l’exploitation de Marx et insiste sur le rôle de Quesnay et de Turgot. L’approche marxiste de l’exploitation doit également à Smith et Ricardo, mais en s’appuyant trop sur Ricardo et sur une mesure en temps de travail de la valeur, Marx rend la mesure empirique de l’exploitation impossible. Il est mis en avant une mesure en prix, dérivée de la théorie du surplus de Quesnay et conservant l’idée que le travail est l’origine de la valeur. La comptabilité nationale doit être la base de l’analyse et il est nécessaire de prendre en compte le rôle de l’État. Codes JEL : B14, B51
Corps politiques, corps mystiques et incorporations
Authors: Brohm Jean-Marie 
Published: January 2019

Le corps social dans la modernité capitaliste est un corps politique (Hobbes, Spinoza, Rousseau). Le pouvoir, quelle que soit sa nature, repose sur la production et reproduction d’une incorporation symbolique ou imaginaire d’un ordre corporel , auquel s’identifient les membres du corps politique (corporations, corps constitués, confréries, corps de métier, congrégations, groupes affinitaires, sociétés secrètes, sectes, etc.). Le pouvoir est également incarné sous la figure d’un chef (président, monarque, tyran, despote, « guide suprême », « grand Timonier », Conducator , « grand leader ») en tant que « représentant corporel de l’État » (Marx). De nombreux corps sociaux ou politiques sont vécus comme des corps mystiques , c’est-à-dire comme des corps collectifs supposés participer d’une réalité transcendante, supra historique, voire supra naturelle, à l’image de l’Église catholique, corps mystique du Christ, ou des deux corps du Roi analysés par Kantorowicz.
Corps mécanisés : extension du domaine de l’obscénité
Authors: Folscheid Dominique 
Published: January 2019

La figure devenue dominante de la sexualité contemporaine est la sexualité clivée entre sa fonction de pure jouissance, qui s’épanouit dans « le sexe », et sa fonction purement génésique, telle qu’elle est mise en œuvre dans les pratiques de procréation médicalement assistée ( amp ), qui se font « hors sexe ». Sont ainsi constitués deux idéals types, exclusifs l’un de l’autre, qui polarisent de plus en plus les demandes. Au prix de la dissociation entre les personnes et leur corps, entre leur corps et leur chair, parce que dans tous les cas nous avons affaire à une entreprise de production – de jouissance ou d’enfant – de nature mécanicienne. Or comme ce clivage s’inscrit sur le fond de la sexualité humaine qui est une et indivisible, il faut s’attendre à des analogies et à des effets de miroir entre ces deux pôles. Et c’est par une approche en termes d’optique, où dominent pulsion scopique et pulsion de maîtrise, que l’on peut commencer à lever le voile sur ce qui se trame.
Michel Foucault et la prison
Authors: Catonné Jean-Philippe 
Published: January 2019

En se fondant sur les écrits de Michel Foucault, l’auteur nous livre une réflexion sur le sens et l’efficacité de la peine et de l’emprisonnement d’un point de vue à la fois politique et psychologique. Pour le détenu d’une part et pour la société qui le détient d’autre part, quel sens prend la sanction ?
