DECIGO and DECIGO pathfinder
A space gravitational-wave antenna, DECIGO (DECI-hertz interferometer Gravitational wave Observatory), will provide fruitful insights into the universe, particularly on the formation mechanism of supermassive black holes, dark energy and the inflation of the universe. In the current pre-conceptual design, DECIGO will be comprising four interferometer units; each interferometer unit will be formed by three drag-free spacecraft with 1000 km separation. Since DECIGO will be an extremely challenging mission with high-precision formation flight with long baseline, it is important to increase the technical feasibility before its planned launch in 2027. Thus, we are planning to launch two milestone missions. DECIGO pathfinder (DPF) is the first milestone mission, and key components for DPF are being tested on ground and in orbit. In this paper, we review the conceptual design and current status of DECIGO and DPF
A CCG-based Compositional Semantics and Inference System for Comparatives
Comparative constructions play an important role in natural language
inference. However, attempts to study semantic representations and logical
inferences for comparatives from the computational perspective are not well
developed, due to the complexity of their syntactic structures and inference
patterns. In this study, using a framework based on Combinatory Categorial
Grammar (CCG), we present a compositional semantics that maps various
comparative constructions in English to semantic representations and introduces
an inference system that effectively handles logical inference with
comparatives, including those involving numeral adjectives, antonyms, and
quantification. We evaluate the performance of our system on the FraCaS test
suite and show that the system can handle a variety of complex logical
inferences with comparatives.Comment: 10 pages, to appear in the Proceedings of PACLIC3

Guided Lock of a Suspended Optical Cavity Enhanced by a Higher Order Extrapolation
Lock acquisition of a suspended optical cavity can be a highly stochastic
process and is therefore nontrivial. Guided lock is a method to make lock
acquisition less stochastic by decelerating the motion of the cavity length
based on an extrapolation of the motion from an instantaneous velocity
measurement. We propose an improved scheme which is less susceptible to seismic
disturbances by incorporating the acceleration as a higher order correction in
the extrapolation. We implemented the new scheme in a 300-m suspended
Fabry-Perot cavity and improved the success rate of lock acquisition by a
factor of 30

A Case of Cat Cry Syndrome Associated with Cleft Lip
AbstractCat cry syndrome (cri-du-chat syndrome) is an extremely rare condition characterized by a high shrill cry during infancy, resulting from either the deletion of the short arm of chromosome 5 or unbalanced translocation inherited from a parent. We report the case of a 1-year-old girl with cat cry syndrome associated with cleft lip. The patient showed a ventricular septal defect, cleft lip, growth and mental retardation, micrognathia, ptosis of the eyelids, hypertelorism, epicanthal folds, and a preauricular tag on the right side. A chromosomal study revealed the terminal deletion of chromosome 5 (46, XX, del(p14.2)ish del(5)). Repair of the cleft lip was carried out concurrently with resection of the preauricular tag, and the patient's postoperative course was uneventful
