Inward foreign direct investment and constitutional change in Scotland

Purpose - To undertake an analysis of the implications of potential Scottish independence for inward foreign direct investment (FDI), multinational enterprise strategies, and the local economy.<p></p> Design/methodology/approach - Takes a multidisciplinary approach drawing upon literature and evidence in the international business and management, political economy, and economic geography fields to analyze the role and impact of inward FDI in Scotland following possible Scottish independence.<p></p> Findings - Scotland continues as an attractive location for FDI, with greater diversity than hitherto. While the country’s comparative advantages in immobile natural resources provide some protection from uncertainty, weak embeddedness is a risk factor irrespective of independence. A range of transition costs of independence are identified, which could be high and of indeterminate duration, and some will be sector-specific. There are also new possibilities for tailoring of policies, and potential reindustrialization opportunities in renewable technologies. The foreign investors most vulnerable to political risks and uncertainties are those whose market scope is the rest of the UK (rUK) either as exporters or value chain integrators, in addition to the high political risk industries of energy, banking, and financial services and defence. Scottish subsidiaries’ significance within their parent MNE groups will also be a major factor in determining responses to political risks and uncertainties.<p></p> Originality/value - Specific focus upon the impact of potential independence on the foreign-owned sector as a major contributor to the Scottish economy.<p></p&gt

Full-revivals in 2-D Quantum Walks

Recurrence of a random walk is described by the Polya number. For quantum walks, recurrence is understood as the return of the walker to the origin, rather than the full-revival of its quantum state. Localization for two dimensional quantum walks is known to exist in the sense of non-vanishing probability distribution in the asymptotic limit. We show on the example of the 2-D Grover walk that one can exploit the effect of localization to construct stationary solutions. Moreover, we find full-revivals of a quantum state with a period of two steps. We prove that there cannot be longer cycles for a four-state quantum walk. Stationary states and revivals result from interference which has no counterpart in classical random walks

Universal diffusion near the golden chaos border

We study local diffusion rate $D$ in Chirikov standard map near the critical golden curve. Numerical simulations confirm the predicted exponent $\alpha=5$ for the power law decay of $D$ as approaching the golden curve via principal resonances with period $q_n$ ($D \sim 1/q^{\alpha}_n$). The universal self-similar structure of diffusion between principal resonances is demonstrated and it is shown that resonances of other type play also an important role.Comment: 4 pages Latex, revtex, 3 uuencoded postscript figure

Nonmydriatic Fundus Photography: A Practical Review for the Neurologist

Declining proficiency in direct ophthalmoscopy by non-ophthalmologists has spurred a search for alternative methods of ocular fundus examination. Recent technological advances have improved the ease of use and quality of non-mydriatic fundus photography, increasing its suitability for clinical care. As the availability of this technology continues to improve, neurologists will need to be familiar with its advantages, limitations and potential applications in the clinical care of patients with neurological conditions

Syngenetic sand veins and anti-syngenetic sand wedges, Tuktoyaktuk Coastlands, western Arctic Canada

Sand-sheet deposits of full-glacial age in the Tuktoyaktuk Coastlands, western Arctic Canada, contain syngenetic sand veins 1-21 cm wide and sometimes exceeding 9 m in height. Their tall and narrow, chimney-like morphology differs from that of known syngenetic ice wedges and indicates an unusually close balance between the rate of sand-sheet aggradation and the frequency of thermal-contraction cracking. The sand sheets also contain rejuvenated (syngenetic) sand wedges that have grown upward from an erosion surface. By contrast, sand sheets of postglacial age contain few or sometimes no intraformational sand veins and wedges, suggesting that the climatic conditions were unfavourable for thermal-contraction cracking. Beneath a postglacial sand sheet near Johnson Bay, sand wedges with unusually wide tops (3.9 m) extend down from a prominent erosion surface. The wedges grew vertically downward during deflation of the ground surface, and represent anti-syngenetic wedges. The distribution of sand veins and wedges within the sand sheets indicates that the existence of continuous permafrost during sand-sheet aggradation can be inferred confidently only during full-glacial conditions

Twisted Quantum Affine Superalgebra Uq[gl(m∣n)(2)]U_q[gl(m|n)^{(2)}] and New Uq[osp(m∣n)]U_q[osp(m|n)] Invariant R-matrices

The minimal irreducible representations of $U_q[gl(m|n)]$, i.e. those irreducible representations that are also irreducible under $U_q[osp(m|n)]$ are investigated and shown to be affinizable to give irreducible representations of the twisted quantum affine superalgebra $U_q[gl(m|n)^{(2)}]$. The $U_q[osp(m|n)]$ invariant R-matrices corresponding to the tensor product of any two minimal representations are constructed, thus extending our twisted tensor product graph method to the supersymmetric case. These give new solutions to the spectral-dependent graded Yang-Baxter equation arising from $U_q[gl(m|n)^{(2)}]$, which exhibit novel features not previously seen in the untwisted or non-super cases.Comment: 19 pages, Latex fil

Community Detection as an Inference Problem

We express community detection as an inference problem of determining the most likely arrangement of communities. We then apply belief propagation and mean-field theory to this problem, and show that this leads to fast, accurate algorithms for community detection.Comment: 4 pages, 2 figure
