A 55-year-old woman, who had two episodes of difficulty in putting a key into a keyhole probably due to optic ataxia at age 52 and 54 years old, developed speaking errors and was admitted to our hospital. She was 152.5 cm in height and 52.5 kg in weight. Neurological examination revealed right homonymous hemianopsia and sensory aphasia. A CSF examination… (More)

There exist logarithmic CFTs(LCFTs) such as the c p,1 models. It is also well known that it generally contains Jordan cell structure. In this paper, we obtain the boundary Ishibashi state for a rank-2 Jordan cell structure and, with these states in c = −2 rational LCFT, we derive boundary states in the closed string picture, which correspond to boundary… (More)

In the olfactory epithelium (OE), olfactory cells (OCs) and supporting cells (SCs), which express different cadherins, are arranged in a characteristic mosaic pattern in which OCs are enclosed by SCs. However, the mechanism underlying this cellular patterning is unclear. Here, we show that the cellular pattern of the OE is established by cellular… (More)

In order to describe two-dimensionally packed cells in epithelial tissues both mathematically and physically, there have been developed several sorts of geometrical models, such as the vertex model, the finite element model, the cell-centered model, the cellular Potts model. So far, in any case, pressures have not neatly been dealt with and the curvatures… (More)

Amongst conformal field theories, there exist logarithmic conformal field theories such as c p,1 models. We have investigated c p,q models with a boundary in search of logarithmic theories and have found logarithmic solutions of two-point functions in the context of the Coulomb gas picture. We have also found the relations between coefficients in the… (More)

In southern India, there are traditional patterns of line-drawings encircling dots, called " Kolam " , among which one-line drawings or the " infinite Kolam " provide very interesting questions in mathematics. For example, we address the following simple question: how many patterns of infinite Kolam can we draw for a given grid pattern of dots? The simplest… (More)

We study the simplest examples of minimal string theory whose world-sheet description is the unitary (p, q) minimal model coupled to two-dimensional gravity (Liouville field theory). In the Liouville sector, we show that four-point correlation functions of 'tachyons' exhibit logarithmic singularities, and that the theory turns out to be logarithmic. The… (More)

3d Chern-Simons gauge theory has a strong connection with 2d conformal field theory and, especially, link invariants in knot theory. On this conventional correspondence, 2d CFT possesses the same gauge symmetry as original CS theory does. In this paper we impose some constraints on the D(2|1; α) CS gauge theory in the similar context of the hamiltonian… (More)

The morphologies of ectodermal organs are shaped by appropriate combinations of several deformation modes, such as invagination and anisotropic tissue elongation. However, how multicellular dynamics are coordinated during deformation processes remains to be elucidated. Here, we developed a four-dimensional (4D) analysis system for tracking cell movement and… (More)

We investigate how different microscopic interactions between semiflexible chain segments can qualitatively alter the physical properties of the condensed toroid. We propose a general form of the Hamiltonian of the toroid and discuss its analytic properties. For different interactions, the theory predicts different scaling behaviors of the mean toroidal and… (More)
