Remarks on Japanese Benefactive V - te moraw Constructions

Sawasaki, Koichi,Nakayama, Mineharu 한국현대언어학회 2001 언어연구 Vol.17 No.2

Koichi Sawasaki & Mineharu Nakayama. 2001. Remarks on Japanese Benefactive V-te moraw Constructions, 언어연구 17-2, 285-314. 이 논문은 일본어의 -te moraw ( …해 받다) 구문에 대한 연구이다. Hoshi (1994)는 -te moraw 구문에 대해, 마치 수동구문에서도 두 가지가 있는 것과 같이 직접 수혜와 간접 수혜 구문의 두 가지 통사적 구조를 제안하였다. 그러나, 우리는 여기서 일본어의 수동구문과 수혜구문은 구조적으로 다르다는 증거를 제시함으로서 Hoshi의 견해를 반박하고자 한다. 첫째, 수동구문에서는 부정어 형태소가 수동형태소 뒤에서만 나타날 수 있지만, -te moraw 구문에서는 앞이나 뒤에다 나타날 수 있다. 둘째, 수동문중 ni-수동문에서 공범주가 명시적인 요소로 채워질 수 없지만, 직접 수혜구문에서는 공범주가 명시적 범주인 zibun으로 채워질 수 있다. 셋째 직접 수혜자구문과 간접수혜자 구문의 경우 zibun과 주어 지향 부사인 wazato가 수동문과는 달리, 강한 주어지향성을 보여준다 이러한 증거를 바탕으로 우리는 수혜구문이 두 개의 IP를 가지고 있다는 제안을 한다. 수혜구문이 이중적인 구조를 가지고 있다는 우리의 제안은 다음과 같은 면에서 Hoshi의 분석과는 다르다. 우선, 이 구문이 수동화 현상과 관련이 없다는 것이다. 둘째, Hoshi의 직/간접 수혜구문이 서로 상호 배타적으로 발생하지만, 우리의 분석에 의하면 결속조건 B가 만족되기만 하면 동시에 발생할 수 있다는 것이다.^1) (The Ohio State University)

Similarity Interference and Scrambling in Japanese

Mineharu Nakayama,Richard L. Lewis 서울대학교 인지과학연구소 2000 Journal of Cognitive Science Vol.1 No.1

Lewis and Nakayama (1999) claim that the difficulty of comprehending sentences is a function, in part, of similarity-based interference, a limitation on working memory. By examining Japanese sentences, they found that the syntactic category, the syntactic position, and the consecutive occurrence of the same category all contribute to the difficulty of sentences. The present study examines the similarity interference hypothesis in Japanese scrambling sentences. According to the hypothesis, the scrambled sentences that reduce similarity interference would be considered easier than the unscrambled sentences. This prediction was borne out. However, the experimental results also showed that sentences with scrambled embedded objects were more difficult than unscrambled sentences. We argue that there are independently-motivated explanations for the difficulty of these sentences. Therefore, the results still support the similarity interference hypothesis, and indeed similarity interference plays a significant role in the difficulty of comprehending sentences.

Combined Analysis of η Meson Hadro- and Photo-production off Nucleons

K. Nakayama,오용석,H. Haberzettl 한국물리학회 2011 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.59 No.2

The η-meson production in photon- and hadron-induced reactions, namely, γp → pη, π^−p → nη, pp → ppη, and pn ∪ pnη, are investigated in a combined analysis in order to learn about the relevant production mechanisms and the possible role of nucleon resonances in these reactions. We consider the nucleonic, mesonic, and nucleon resonance currents constructed within an effective Lagrangian approach and compare the results with the available data for cross sections and spin asymmetries for these reactions. We found that the reaction γp → pη could be described well with the inclusion of the well-established S_(11)(1535), S_(11)(1650), D_(13)(1520), and D_(13)(1700) resonances, in addition to the mesonic current. Consideration of other well-established resonances in the same mass region, including the spin-5/2 resonances, D_(15)(1675) and F_(15)(1680), does not further improve the results qualitatively. For the reaction π_−p → nη, the P_(13)(1720) resonance is found to be important for reproducing the structure observed in the differential cross section data. Our model also improves the description of the reaction NN → NNη to a large extent compared to the earlier results by Nakayama et al. [Phys. Rev. C 68, 045201 (2003)]. For this reaction, we address two cases where either the S_(11)(1535) or the D_(13) dominates. Further improvement in the description of these reactions and the difficulty to uniquely determine the nucleon resonance parameters in the present type of analysis are discussed.

Unitarity meets channel-duality for rolling/decaying D-branes

Nakayama, Yu,Rey, Soo-Jong,Sugawara, Yuji IOP Publishing Ltd 2006 Journal of high energy physics Vol.2006 No.8

Investigations for decay of unstable D-brane and rolling of accelerated D-brane dynamics have revealed that various proposed prescriptions give different result for spectral amplitudes and observables. Here, we study them with particular attention to unitarity and open-closed channel duality. From <I>ab initio</I> derivation in the open string channel, both in Euclidean and Lorentzian worldsheet approaches, we find heretofore overlooked contribution to the spectral amplitudes and obervables. The contribution is fortuitously absent for decay of unstable D-brane, but is present for rolling of accelerated D-brane. We finally show that the contribution is imperative for ensuring unitarity and optical theorem at each order in string loop expansion.

APPLICATION OF BACKSCATTER AND COHERENCE DATA ON C AND L BAND FOR LANDCOVER IDENTIFICATION IN TROPICS

Nakayama, Mikiyasu 대한원격탐사학회 1999 International Symposium on Remote Sensing Vol.15 No.1

Use of coherence data from operational satellite based SAR sensors has been experimented both on C and L band to identify landcover in tropics. While coherence data proved useful to improve accuracy in landcover identification, such data are not readily available. On the other hand, integrated use of backcatter data by multiple satellites is readily feasible. The very question to be asked is whether integration of backscatter data on multiple bands (e.g. C and L band) is either inferior or superior to use of coherence data. We therefore still do not have a solid clue to answer to the very question. The aim of this study is to evaluate the performance of $quot;integrated use$quot; of backscatter data on C and L band (by ERS and JERS respectively) to identify landcover, vis-a-vis the same by combination of backscatter and coherence data by single satellite. The study was carried out for an area in the southern part of the Sumatra Island, Indonesia. The area has been intensively converted from natural forest into plantation. Five categories of landcover exist in this study area. By ERS-1, only 2 or 3 classes may be identified with the backscatter data alone, while adding the coherence data could delineate 4 classes. By JERS-1, only 3 to 4 classes may be identified with the backscatter data alone, while 4 classes could be clearly delineated by adding the coherence data. By integrating backscatter data on two bands, 4 to 5 classes may be identified. It represents the best results among cases examined. The outcome of the study suggests that integrated use of backscatter data on two bands by ERS and JERS is as powerful as use of backscatter and coherence data on single band by one of these satellite.

Observables and correlators in non-relativistic ABJM theory

Nakayama, Yu,Rey, Soo-Jong IOP Publishing Ltd 2009 Journal of high energy physics Vol.2009 No.8

Non-relativistic ABJM theory is defined by Galilean limit of mass-deformed &calN; = 6 Chern-Simons theory. Holographic string theory dual to the theory is not known yet. To understand features candidate gravity dual might exhibit, we examine local and nonlocal physical observables and their correlations in the non-relativistic ABJM theory. We show that gauge invariant local observables correspond to zero-norm states and that correlation functions among them are trivial. We also show that a particular class of nonlocal observables, Wilson loops, are topological in the sense that their correlation functions coincide with those of pure Chern-Simons theory. We argue that the theory is nevertheless physical and illustrate several physical observables whose correlation functions are nontrivial. We also study quantum aspects. We show that Chern-Simons level is finitely renormalized and that dilatation operator is trivial at planar limit. These results all point to string scale geometry of gravity dual and to intriguing topological and tensionless nature of dual string or M theory defined on it.

Evaluation of H₂ / Air Fuel Cell having an Anion Exchange Membrane with the Cole-Cole Plot method

Nakayama, Yusei,Katayama, Noboru,Kogoshi, Sumio The Korean Institute of Electrical Engineers 2012 The Journal of International Council on Electrical Vol.2 No.1

Evaluation of $H_2$ / air fuel cell having an anion exchange membrane with the Cole-Cole plot method has been studied. $H_2$ was supplied to the anode at a constant flow rate and air was supplied to the cathode. The Cole-Cole plots have been measured while changing the air flow rate of the cathode. The obtained Cole-Cole plots have been evaluated by using the equivalent circuit of the fuel cell to get values of the membrane resistance and the reactive resistance. The experimental results show that the membrane value was slightly increased with increasing the air flow rate. On the other hand, the reactive resistance value decreased from 434 $m{\Omega}/cm^2$ to 181 $m{\Omega}/cm^2$. And the maximum power density was increased with decreasing the reactive resistance. They reveal that more influence on the performance of AEMFC is due to the reactive resistance. Decreasing the reactive resistance would improve the performance.
