On the diffusive propagation of warps in thin accretion discs

In this paper we revisit the issue of the propagation of warps in thin and viscous accretion discs. In this regime warps are know to propagate diffusively, with a diffusion coefficient approximately inversely proportional to the disc viscosity. Previous numerical investigations of this problem (Lodato & Pringle 2007) did not find a good agreement between the numerical results and the predictions of the analytic theories of warp propagation, both in the linear and in the non-linear case. Here, we take advantage of a new, low-memory and highly efficient SPH code to run a large set of very high resolution simulations (up to 20 million SPH particles) of warp propagation, implementing an isotropic disc viscosity in different ways, to investigate the origin of the discrepancy between the theory and the numerical results. Our new and improved analysis now shows a remarkable agreement with the analytic theory both in the linear and in the non-linear regime, in terms of warp diffusion coefficient and precession rate. It is worth noting that the resulting diffusion coefficient is inversely proportional to the disc viscosity only for small amplitude warps and small values of the disc $\alpha$ coefficient ($\alpha < 0.1$). For non-linear warps, the diffusion coefficient is a function of both radius and time, and is significantly smaller than the standard value. Warped accretion discs are present in many contexts, from protostellar discs to accretion discs around supermassive black holes. In all such cases, the exact value of the warp diffusion coefficient may strongly affect the evolution of the system and therefore its careful evaluation is critical in order to correctly estimate the system dynamics (abridged).Comment: 16 pages, 14 figures.

A disconnected political class, poor communication from politicians, and inadequate political education continue to put young people off politics

One of the defining democratic challenges of our time is the detachment of young people from the political process. Martin Price, who manages Warwick University’s youth political engagement project MyPlace, who here presents a video in which young people express their thoughts on the problem, argues that a disconnected political class, the inadequate communication of politicians, and below-par political education are all at fault

There is a clear disconnect between young people and political institutions. The Electoral Commission’s proposals to boost engagement will not address this problem

The Electoral Commission released a report outlining changes, such as same-day voter registration and e-voting, they believe will make citizens more engaged with the democratic process. However, research shows the motivations underlying young people’s participation in political processes is more rooted in people not seeing the point of voting for individuals and institutions rather than not being able to work out how. It would seem to be something of a red herring to pursue the proposed ‘fixed’ when actually the issue is one of hearts and minds, writes Martin Price

Voyager electronic parts radiation program, volume 1

The Voyager spacecraft is subject to radiation from external natural space, from radioisotope thermoelectric generators and heater units, and from the internal environment where penetrating electrons generate surface ionization effects in semiconductor devices. Methods for radiation hardening and tests for radiation sensitivity are described. Results of characterization testing and sample screening of over 200 semiconductor devices in a radiation environment are summarized

Taking Sides: Urban Wandering as Decolonial Translation and Critique of Settler Colonialism

Abstract: Colonialism fragments meaning. This essay takes up colonial fragmentation of meaning as a question of translation. It offers a decolonial methodology to unpack the political stakes as one moves back and forth across the colonial line. The methodology is based on a conscious process of urban wandering or drifting, what the Situationists called the “dérive.” Two case studies of itinerant decolonial theorizing follow. The first is a sketch of the militarized border between the US and Mexico, and the second example has to do with Columbus Day/Indigenous Peoples’ Day. In the case studies, translating is treated as a question of “tuning in” as one tunes into a conversation, or, alternatively, as if into a radio frequency. The metaphor of translation-as-tuning-in allows us to address practical and concrete questions of translation in everyday settings, as well as contemporary theoretical debates in translation studies. Keywords: translation; colonialism; decolonial methodology; border; dériveResumen: El colonialismo fragmenta el significado. Este ensayo aborda la fragmentación colonial del significado como una cuestión de traducción. Se propone plantear una metodología descolonial para desentrañar los intereses y las apuestas políticas que supone desplazarnos a lo largo de la línea colonial, con base en un proceso autoconsciente de divagación urbana, lo que los situacionistas denominan la “deriva.” Para este fin se presentan dos casos de lo que planteamos como una teorización descolonial itinerante. El primero es un bosquejo de la frontera militarizada entre Estados Unidos y México, y el segundo tiene que ver con la diferencia entre la designación del llamado Día de la Raza (en inglés "día de Colón") / Día de los Pueblos Indígenas. En estos casos se aborda la traducción como una cuestión de “sintonización”, en el sentido de sintonizarnos a una conversación, o a una frecuencia radial. La metáfora de la traducción-como-sintonización nos permite analizar cuestiones prácticas y concretas de la traducción en entornos cotidianos, así como también comentar debates teóricos de la traductología contemporánea. Palabras clave: traducción; colonialismo; metodología descolonial; frontera; derivaRésumé&nbsp;: Le colonialisme fragmente le sens. Dans cet article, où la fragmentation coloniale du sens est une question de traduction, l’auteur recourt à une méthodologie décoloniale dans le but d’examiner les enjeux politiques rencontrés lorsque l’on évolue d’un côté puis de l’autre de la frontière du colonialisme. Le travail est fondé sur un processus conscient d’errance ou de flânerie urbaine, que les Situationnistes appellent dérive. Deux études de cas pour théoriser le décolonialisme itinérant sont ainsi proposées. La première est une esquisse de la frontière militarisée entre les États-Unis et le Mexique. Le second exemple concerne Colombus Day (jour férié aux États-Unis) et la journée des peuples autochtones. Dans cette étude de cas, la traduction est une question d’ajustement, tout comme quelqu’un qui s’ajuste à une conversation, ou tout comme on ajuste une fréquence radio. La métaphore d’une traduction qui mène à un ajustement nous permet de répondre à des questions concrètes et pratique de traduction dans nos contextes quotidiens, comme dans les débats théoriques contemporains en traductologie.&nbsp; Mots clés : traduction; colonialisme; méthodologie décoloniale; frontière; dériveResumo: O colonialismo fragmenta o sentido. Este ensaio toma a fragmentação colonial do sentido como uma questão de tradução e oferece uma metodologia decolonial para desvendar suas implicações políticas na medida em que nos movemos de uma lado para o outro da linha colonial. A metodologia baseia-se no processo autoconsciente de errância, de um estar à deriva no espaço urbano, o que os Situacionistas chamavam de “dérive”. Dois estudos de caso baseados na perspectiva teórica decolonial itinerante são apresentados. O primeiro é um esboço da fronteira militar entre os EUA e o México, o segundo está relacionado ao Dia de Colombo e ao Dia do Índio. Nos estudos de caso, traduzir é tratado como uma questão de sintonizar-se, como&nbsp; em uma conversa ou estação de rádio. A metáfora da tradução com o ato de sintonizar nos permite endereçar as questões práticas e concretas da tradução em situações cotidianas, bem como nos debates contemporâneos dos estudos da tradução.
