Ethics in the Multijurisdictional Practice of Admiralty Lawyers

In June 2002 the Commission on Multijurisdictional Practice of the American Bar Association (“ABA”) issued a report which covered a wide range of subjects including state judicial regulation and discipline of lawyers, the special problems of large firms moving lawyers around to work in branch offices, the use of in-house counsel not licensed in the state where they work, the particular problems of federal government and military lawyers practicing as part of their official duties in states where they are not licensed, as well as model rules for admission to practice on motion, for licensing of foreign legal consultants, and for admission pro hac vice in lawsuits. The focus of this Essay, however, is limited to just the activities which admiralty lawyers—and many other international lawyers—routinely engage in, which could be regarded by some courts or licensing authorities as the unauthorized practice of law. (P) ‘In general, a lawyer may not represent clients in court, or otherwise practice law within a particular state, unless the lawyer is licensed by the state to do so. By limiting law practice to those whom the state judiciary, through its admissions process, has deemed to be qualified to practice law in the state, a state government tries to ensure that lawyers who act on behalf of or give advice to clients in the state are competent and do so ethically. States give effect to restrictions through rules of professional conduct, which subject lawyers to the risk of sanction (in some states, criminal sanction) for practicing law within a state where they are not licensed, by treating such lawyers the same as laymen. Needless to say, a lawyer found by out-of-state authorities to have engaged in the unauthorized practice of law will also have many problems at home. (P) Today, every jurisdiction permits pro hac vice admission of out-of-state lawyers appearing in court or before some other tribunal/ But for transactional and counseling work, and other activities—including work done prior to commencement of a formal proceeding—there is no counterpart to pro hac vice admission

Ramanujan Graphs in Polynomial Time

The recent work by Marcus, Spielman and Srivastava proves the existence of bipartite Ramanujan (multi)graphs of all degrees and all sizes. However, that paper did not provide a polynomial time algorithm to actually compute such graphs. Here, we provide a polynomial time algorithm to compute certain expected characteristic polynomials related to this construction. This leads to a deterministic polynomial time algorithm to compute bipartite Ramanujan (multi)graphs of all degrees and all sizes

Hazard's Toll: The Costs of Inaction at the Salton Sea

The objective of this report is to estimate the costs of inaction - defined as the absence of any large-scale revitalization or air quality management project - at the Salton Sea, to provide decision-makers and the general public with information for deciding on a path forward

The Synthesis of Arbitrary Stable Dynamics in Non-linear Neural Networks II: Feedback and Universality

We wish to construct a realization theory of stable neural networks and use this theory to model the variety of stable dynamics apparent in natural data. Such a theory should have numerous applications to constructing specific artificial neural networks with desired dynamical behavior. The networks used in this theory should have well understood dynamics yet be as diverse as possible to capture natural diversity. In this article, I describe a parameterized family of higher order, gradient-like neural networks which have known arbitrary equilibria with unstable manifolds of known specified dimension. Moreover, any system with hyperbolic dynamics is conjugate to one of these systems in a neighborhood of the equilibrium points. Prior work on how to synthesize attractors using dynamical systems theory, optimization, or direct parametric. fits to known stable systems, is either non-constructive, lacks generality, or has unspecified attracting equilibria. More specifically, We construct a parameterized family of gradient-like neural networks with a simple feedback rule which will generate equilibrium points with a set of unstable manifolds of specified dimension. Strict Lyapunov functions and nested periodic orbits are obtained for these systems and used as a method of synthesis to generate a large family of systems with the same local dynamics. This work is applied to show how one can interpolate finite sets of data, on nested periodic orbits.Air Force Office of Scientific Research (90-0128

Growth and Recovery in a Time of Default: Lessons from the Role of the Urban Sector in Argentina

International narratives on Argentina’s recovery from the crisis of 2001-02 tend to emphasize the role of rising commodity prices and growing demand from China. Argentina is said to have been ‘lucky’, saved by global demand for its agricultural exports. The international narrative has also been used by local agricultural exporters to justify their objections against higher export taxes during periods of high commodity prices. These narratives are not correct. Data on the country’s recovery show that it was not led by agricultural exports but was fuelled by urban demand and production. When the Convertibility period ended and the peso was devalued in 2002, price increases for imports stimulated the production of domestic goods and services for consumers. This production in turn generated multiplier effects which supported small and medium-sized firms and helped to create many new jobs. This later produced a revival of the construction and then the manufacturing sectors as well.economic crisis, urban sector, economic recovery

Modeling the Contributions of the Exocytotic Machinery and Receptor Desensitization to Short- and Long-Term Plasticity of Synapses Between Neocortical Pyramidal Neurons

Short-term synaptic depression (STD) refers to the progressive decrease in synaptic efficacy during a spike train. This decrease may be explained in terms of presynaptic and postsynaptic processes, such as a decrease in the probability of transmitter release, and postsynaptic receptor desensitization. STD may be very strong, and is release-dependent in neocortical pyramid-pyramid synapses. Using a stochastic synapse model, we suggest that the main source of depression in these synapses is the step of vesicle priming, while vesicle depletion and postsynaptic receptor desensitization are proposed to play a lesser role. Our results suggest that vesicle priming may explain not only the release-dependent nature of STD, but also the observation that an average of about one vesicle per active zone is released in central synapses, without positing forced univesicular release. We propose that the latter phenomenon is due to a low priming probability. Our results also explain the effect of paired pre- and postsynaptic activity on STD. In neocortical pyramid-pyramid synapses pairing induces a form of long-term potentiation that has been described as a redistribution of synaptic efficacy (RSE). We propose that RSE is due to a pairing-induced increase in the probability that a primed vesicle will undergo release in response to a presynaptic action potential. This increase may be due to an increased Ca^2+ influx through voltage-gated Ca^2+ channels, or to an increased sensitivity of primed vesicles to this influx. The results were obtained by constraining the model with experimentally observed levels of release probability and other synaptic variables.Defense Advanced Research Projects Agency and the Office of Naval Research (N00014-95-l-0409); Office of Naval Research (N00014-95-l-0657)

Numerically exact full counting statistics of the energy current in the Kondo regime

We use the inchworm Quantum Monte Carlo method to investigate the full counting statistics of particle and energy currents in a strongly correlated quantum dot. Our method is used to extract the heat fluctuations and entropy production of a quantum thermoelectric device, as well as cumulants of the particle and energy currents. The energy--particle current cross correlations reveal information on the preparation of the system and the interplay of thermal and electric currents. We furthermore demonstrate the signature of a crossover from Coulomb blockade to Kondo physics in the energy current fluctuations, and show how the conventional master equation approach to full counting statistics systematically fails to capture this crossover
