As I have pointed out in a series of papers, which appeared about fifteen years ago in the Revue de l'histoire des religions, there are numerous resemblances between the ancient myths of the Indo-Europeans, on the one hand, and those of Japan, on the other. These resemblances, relating both to the fundamental structures of the two mythological systems and to a number of curious details, constitute an assemblage which seems too conspicuous to be regarded as either accidental or the result (...) of a similitude of human mentalities, manifesting itself, so it seems, through the creation of a great many similar myths and legends throughout the length and breadth of the surface of our planet.

Establishment of cell lineage identity from multipotent progenitors is controlled by cooperative actions of lineage‐specific and stably expressed transcription factors, combined with input from environmental signals. Lineage‐specific master transcription factors activate and repress gene expression by recruiting consistently expressed transcription factors and chromatin modifiers to their target loci. Recent technical advances in genome‐wide and multi‐omics analysis have shed light on unexpected mechanisms that underlie more complicated actions of transcription factors in cell fate decisions. In this review, we discuss functional dynamics (...) of stably expressed and continuously required factors, Notch and Runx family members, throughout developmental stages of early T cell development in the thymus. Pre‐ and post‐commitment stage‐specific transcription factors induce dynamic redeployment of Notch and Runx binding genomic regions. Thus, together with stage‐specific transcription factors, shared transcription factors across distinct developmental stages regulate acquisition of T lineage identity. (shrink)

This collection of classic works from the mid-nineteenth through mid-twentieth centuries was originally published under the auspices of the Royal Asiastic Society. Spanning over 100 years in oriental scholarship, primary texts include work by Frederic Rosen, W.F. Thompson, C. Edward Sachau, R.A. Nicholson, W.H.T. Gairdner, W.M. Miller, James Robson, and many others.

We study the dynamics of a vortex in superfluid He4. This is carried out by deriving the effective Lagrangian for the center of the vortex by starting with the time-dependent Ginzburg-Landau formalism. From the resultant equation of motion for a vortex, we arrive at a novel aspect for the Magnus force which has long been known in fluid dynamics. This force has a geometric origin and is expected to occur in other form of condensates such as vortex excitations for quantum (...) Hall fluids or ferromagnets. We also consider the force of non geometric origin, the pinning force coming from the impurity. (shrink)

In this paper, we would present an overview of the recent studies on the role of diagram in mathematics. Traditionally, mathematicians and philosophers had thought that diagram should not be used in mathematical proofs, because relying on diagram would cause to various types of fallacies. But recently, some logicians and philosophers try to show that diagram has a legitimate place in proving mathematical theorems. We would review such trends of studies and provide some perspective from viewpoint of philosophy of mathematics.

Reasoning with conditionals is often thought to be non-monotonic, but there is no incompatibility with classical logic, and no need to formalise inference itself as probabilistic. When the addition of a new premise leads to abandonment of a previously compelling conclusion reached by modus ponens, for example, this is generally because it is hard to think of a model in which the conditional and the new premise are true.

This paper studies a fundamental mechanism by which conflicts between arguments are drawn from sentiments regarding acceptability of the arguments. Given sets of arguments, an inverse abstract argumentation problem seeks attack relations between arguments such that acceptability semantics interprets each argument in the sets of arguments as being acceptable in each of the attack relations. It is an inverse problem of the traditional problem we refer to as the forward abstract argumentation problem. Given an attack relation, the forward abstract argumentation (...) problem seeks sets of arguments such that acceptability semantics interprets each argument in the sets of arguments as being acceptable in the attack relation. We give a probabilistic model of argumentation-theoretic inference. It is a generative model formalising the process by which acceptability semantics interprets acceptability of arguments in a given attack relation. We show that it gives a broad view of solutions to the forward and inverse abstract argumentation problems. Specifically, solutions to the inverse and forward abstract argumentation problems are shown to be equivalent to a maximum likelihood estimate and maximum likelihood prediction, respectively, which are both available with the generative model. In addition, they are shown to be special cases of the posterior distribution and the evidence, respectively, which are both obtained by probabilistic inference on the generative model. We report an experiment result and application example of the generative model in the inverse problems. (shrink)
