Modelling oscillations in the jet emission from microquasar GRS 1915+105
No full textThe variability in the infrared to millimetre emission from microquasar GRS 1915+105 is believed to be dominated by the system's relativistic jet. In this paper we develop a time-dependent version of the jet emission model of Blandford & Königl and apply it to the oscillations in the infrared and millimetre emission from GRS 1915+105 observed recently by Fender & Pooley. The resulting model provides a reasonable description of the observed flux oscillations from GRS 1915+105. From a fit of the observed time lag between the flux peaks in the infrared and millimetre emission together with the flux normalization, we were able to determine the model parameters for the GRS 1915+105 jet. We find that to achieve the observed flux levels with the model requires an unphysically large electron density within the jet. We therefore conclude that the Blandford & Königl model cannot explain these observations, either because it does not provide the correct description of the emission from microquasar jets, or because the observed emission variations do not originate in the jet
A Note on Implementing Box-Cox Quantile Regression
No full textThe Box-Cox quantile regression model using the two stage method suggested by Chamberlain (1994) and Buchinsky (1995) provides a flexible and numerically attractive extension of linear quantile regression techniques. However, the objective function in stage two of the method may not exists. We suggest a simple modification of the estimator which is easy to implement. The modified estimator is still pn{consistent and we derive its asymptotic distribution. A simulation study confirms that the modified estimator works well in situations, where the original estimator is not well defined. --Box-Cox quantile regression,iterative estimator
People at Cox Ranch
No full textImage shows three men and three women standing on or in front of the porch of what appears to be a long, white building. Older database indicates the people are (from left to right): Mrs. Sweezey, Harriet Bentley (on ground), Mrs. W.W. Cox, W.W. Cox's nephew (Ed Cox), C.R. Piquero, and Jim Hestor (Cox Ranch foreman). Database also indicates that the image comes from the Cox Ranch in Organ, New Mexico
La politica della legalità : il ruolo del giurista nell'età contemporanea
No full textAs the author of this book shows as he tests his theses, impartiality and justice require specific and scrupulous forms of civil engagement which render obsolete the traditional call for neutrality. At the same time, citizens must be made to understand how formal features of law that usually evoke their hostility actually guarantee their rights. The legal professional must learn to be a "relativist", obliged - through his choices - to establish priorities among distinct and often irreconcilable value domains
Cercando di dimenticare Savigny
No full textIl presente scritto è un contributo alla discussione del libro di Aurelio Gentili, Il
diritto come discorso del 2013. Del predetto volume si approvano senza riserve
a) la critica alla concezione del vecchio positivismo, secondo il quale il giurista
non farebbe altro che esplorare un misterioso oggetto denominato “realtà
giuridica”, e b) l’interesse per le tecniche argomentative quali strumenti di
controllo interno dei discorsi. Sul piano propositivo, l’autore della recensione
ammette che la conoscenza dei significati normativi letterali, quando la si
ritiene rilevante, comporta a livello collettivo (ma assai meno al livello dei
singoli) un giudizio partecipante. Tali significati, del resto, lungi dall’essere
entità fisse, sono sempre in movimento. Ciò stabilito e con questi limiti,
occorre ammettere che non c’è solo un ordo ordinans imposto dai giuristi sui
confusi materiali estratti dalle fonti, ma si può scorgere, e si deve ritrovare,
anche un ordo ordinatus, frutto tanto dell’attività legislativa quanto delle precedenti interpretazioni, che il singolo interprete non può far a meno di
riconoscere. Insomma: tra i due ordini, fra le attività dei giuristi e i prodotti di
tali attività, si stabilisce un rapporto dialettico.This article is a contribution to the discussion regarding Aurelio Gentili’s 2013
book Il diritto come discorso. From the said volume, the author fully approves:
a) the criticism of the old positivism’s conception that a lawyer does nothing
but explore the misterious object that is “legal reality”, and b) the interest in
argumentative techniques as instruments for internal control of discourses. The
author of this article proposes admitting that the knowledge of literal normative
meanings, when believed to be relevant, requires at the level of the collective
(much less so at the individual level) a judgment, which demonstrates
participation. These meanings are, moreover, far from being fixed entities,
always changing. Within these limits, it should be admitted that there is not
only an ordo ordinans, made by the jurists, using the confused materials
extracted from the sources, but that we may also observe, and must rediscover,
an ordo ordinatus, which results from both legislative activity and previous
interpretations – that an individual interpreter cannot but recognize. In short, a
dialectic relationship between the two orders, between the activity of lawyers
and the products of these activities, is thus established

Exact two-dimensionalization of low-magnetic-Reynolds-number flows subject to a strong magnetic field
No full textWe investigate the behavior of flows, including turbulent flows, driven by a horizontal body-force and subject to a vertical magnetic field, with the following question in mind: for very strong applied magnetic field, is the flow mostly two-dimensional, with remaining weak three-dimensional fluctuations, or does it become exactly 2D, with no dependence along the vertical? We restrict attention to low-magnetic-Reynolds number (Rm) flow. Because liquid metals have low magnetic Prandtl number, such low- flows can have a kinetic Reynolds number as large as one million and therefore be strongly turbulent. We first focus on the quasi-static approximation, i.e. the asymptotic limit of vanishing magnetic Reynolds number Rm << 1: we prove that the flow becomes exactly 2D asymptotically in time, regardless of the initial condition and provided the interaction parameter N is larger than a threshold value. We call this property absolute two-dimensionalization: the attractor of the system is necessarily a (possibly turbulent) 2D flow. We then consider the full-magnetohydrodynamic equations and we prove that, for low enough Rm and large enough N, the flow becomes exactly two-dimensional in the long-time limit provided the initial vertically-dependent perturbations are infinitesimal. We call this phenomenon linear two-dimensionalization: the (possibly turbulent) 2D flow is an attractor of the dynamics, but it is not necessarily the only attractor of the system. Some 3D attractors may also exist and be attained for strong enough initial 3D perturbations. These results shed some light on the existence of a dissipative anomaly for magnetohydrodynamic flows subject to a strong external magnetic field

Flow instabilities and reversals in non-uniformly thermocapillary driven melt pool
No full textWith transient LES and DNS simulations, we investigate flow in melt pools driven by thermocapillary forces. The developing pool is at first axisymmetric as are the boundary conditions, but flow instabilities arise that lead to 3D oscillatory flow patterns. At higher laser powers a sign-change in the surface tension temperature coefficient occurs, resulting in a flow reversal in the pool and thus two counter-rotating vortices, which exhibit similar though more complex flow instabilities
