Kaley v. United States: The Right to Counsel of Choice Caught in the Wide Net of Asset Forfeiture

This commentary previews an upcoming Supreme Court case, Kaley v. United States, in which the Court may decide whether a defendant who needs potentially forfeitable assets to retain counsel of choice is entitled, under the Due Process Clause, to a hearing to challenge the grand jury\u27s finding of probable cause

Random Variables Recorded under Mutually Exclusive Conditions: Contextuality-by-Default

We present general principles underlying analysis of the dependence of random variables (outputs) on deterministic conditions (inputs). Random outputs recorded under mutually exclusive input values are labeled by these values and considered stochastically unrelated, possessing no joint distribution. An input that does not directly influence an output creates a context for the latter. Any constraint imposed on the dependence of random outputs on inputs can be characterized by considering all possible couplings (joint distributions) imposed on stochastically unrelated outputs. The target application of these principles is a quantum mechanical system of entangled particles, with directions of spin measurements chosen for each particle being inputs and the spins recorded outputs. The sphere of applicability, however, spans systems across physical, biological, and behavioral sciences.Comment: In H. Liljenstr\"om (Ed.) Advances in Cognitive Neurodynamics IV (pp. 405-410) (2015

Aboriginal Child Welfare

As the relationships between Canada’s Aboriginal peoples and the state undergo changes, the issue of Child Welfare is in the foreground; for it is around the well being, education and care of Aboriginal children that much of the painful historical relationship between First Nations and Canadian government has been played out. In this paper we consider the major issues in Canadian Aboriginal child welfare, drawing upon an extensive review and synthesis of current theory and research. Although there is an abundance of material available concerning Aboriginal child welfare, much of it exists outside mainstream academic child welfare literature. Some of the salient work on Aboriginal child welfare is contained in the justice literature and much is contained in evaluation reports, operational reviews, submissions to government bodies and in oral stories and testimony. Our goal has been to cull these sources in order to present a coherent understanding of Aboriginal child welfare issues that encompasses history, theoretical analysis, politics, visions, realities, education, evaluation and aspirations

The Antero-inferior Premaxillary Approach to Surgery of the Nasal Septum

The technique of operation for preservation of the cartilaginous septum of the nose is described in detail. There are several very good reasons for preserving the cartilage, among which are added stability of the nose, considerably improved function, and fewer complications, In fact, this operation can be done with safety in young children. A few extra instruments are required and the technique requires some studying.S. Afr. Med. J. 47, 1 (1973

Typical state of an isolated quantum system with fixed energy and unrestricted participation of eigenstates

This work describes the statistics for the occupation numbers of quantum levels in a large isolated quantum system, where all possible superpositions of eigenstates are allowed, provided all these superpositions have the same fixed energy. Such a condition is not equivalent to the conventional micro-canonical condition, because the latter limits the participating eigenstates to a very narrow energy window. The statistics is obtained analytically for both the entire system and its small subsystem. In a significant departure from the Boltzmann-Gibbs statistics, the average occupation numbers of quantum states exhibit in the present case weak algebraic dependence on energy. In the macroscopic limit, this dependence is routinely accompanied by the condensation into the lowest energy quantum state. This work contains initial numerical tests of the above statistics for finite systems, and also reports the following numerical finding: When the basis states of large but finite random matrix Hamiltonians are expanded in terms of eigenstates, the participation of eigenstates in such an expansion obeys the newly obtained statistics. The above statistics might be observable in small quantum systems, but for the macroscopic systems, it rather reenforces doubts about self-sufficiency of non-relativistic quantum mechanics for justifying the Boltzmann-Gibbs equilibrium.Comment: 20 pages, 3 figure

Regression relation for pure quantum states and its implications for efficient computing

We obtain a modified version of the Onsager regression relation for the expectation values of quantum-mechanical operators in pure quantum states of isolated many-body quantum systems. We use the insights gained from this relation to show that high-temperature time correlation functions in many-body quantum systems can be controllably computed without complete diagonalization of the Hamiltonians, using instead the direct integration of the Schroedinger equation for randomly sampled pure states. This method is also applicable to quantum quenches and other situations describable by time-dependent many-body Hamiltonians. The method implies exponential reduction of the computer memory requirement in comparison with the complete diagonalization. We illustrate the method by numerically computing infinite-temperature correlation functions for translationally invariant Heisenberg chains of up to 29 spins 1/2. Thereby, we also test the spin diffusion hypothesis and find it in a satisfactory agreement with the numerical results. Both the derivation of the modified regression relation and the justification of the computational method are based on the notion of quantum typicality.Comment: 16 pages, 4 figures; minor textual corrections; parts rearrange

Dimensionality of spin modulations in 1/8-doped lanthanum cuprates from the perspective of NQR and muSR experiments

We investigate the dimensionality of inhomogeneous spin modulation patterns in the cuprate family of high-temperature superconductors with particular focus on 1/8-doped lanthanum cuprates. We compare one-dimensional stripe modulation pattern with two-dimensional checkerboard of spin vortices in the context of nuclear quadrupole resonance(NQR) and muon spin rotation(muSR) experiments. In addition, we also consider the third pattern, a two-dimensional superposition of spin spirals. Overall, we have found that none of the above patterns leads to a consistent interpretation of the two types of experiments considered. This, in particular, implies that the spin vortex checkerboard cannot be ruled out on the basis of available NQR/muSR experimental results.Comment: 6 pages, 2 figure
