Orphan drugs revisited.[comment] (2006)
McCabe, C., Tsuchiya, A., Claxton, K., Raftery, J.
Hughes et al.1 recently discussed arguments for and against giving special funding status to orphan drugs in this journal. They concluded that there should be a uniform policy across Europe, that...
Using rank data to estimate health state utility models (2006)
McCabe, C., Brazier, J., Gilks, P., Tsuchiya, A., Roberts, J., O'Hagan, A., ...
In this paper we report the estimation of conditional logistic regression models for the Health Utilities Index Mark 2 and the SF-6D, using ordinal preference data. The results are compared to the...
Orphan drugs and the NHS: Should we value rarity (2005)
McCabe, C., Claxton, K., Tsuchiya, A.
Cost effectiveness plays an important part in current decisions about the funding of health technologies. Drugs for rare disease (orphan drugs) are often expensive to produce and, by definition, will...

A comparison of the EQ-5D and the SF-6D across seven patient groups (2004)
Brazier, J.E., Tsuchiya, A., Roberts, J., Busschbach, J.
As the number of preference-based instruments grows, it becomes increasingly important to compare different preference-based measures of health in order to inform an important debate on the choice of...

Aoki, Y., Tsuchiya, A., Kanayama, T., Saha, S. R., Sugawara, H., Sato, H., ...
We report on muon spin relaxation measurements of the 4f^2-based heavy-fermion superconductor filled-skutterudite PrOs4Sb12. The results reveal the spontaneous appearance of static internal magnetic...
Aoki, H., Iso, S., Kawai, H., Kitazawa, Y., Tada, T., Tsuchiya, A.
We review our proposal for a constructive definition of superstring, type IIB matrix model. The IIB matrix model is a manifestly covariant model for space-time and matter which possesses N=2...
We review the construction and theoretical implications of the USp(2k) matrix model in zero dimension introduced in ref. \cite{IT1,IT2}. It is argued that the model provides a constructive approach...
USp(2k) Matrix Model: Schwinger-Dyson Equations and Closed-Open String Interactions (1998)
We derive the Schwinger-Dyson/loop equations for the USp(2k) matrix model which close among the closed and open Wilson loop variables. These loop equations exhibit a complete set of the joining and...
Dynamical Properties of Large N Reduced Model of Yang-Mills Theory (1998)
Hotta, T., Nishimura, J., Tsuchiya, A.
We study the large N reduced model of D-dimensional Yang-Mills theory with special attention to the dynamical aspects related to the eigenvalues of the NxN matrices, which correspond to the...
A Unified Approach to Solvable Models of Dilaton Gravity in Two-Dimensions Based on Symmetry (1998)
Y. Kazama, Y. Satoh, A. Tsuchiya
A large class of solvable models of dilaton gravity in two space-time dimensions, capable of describing black hole geometry, are analyzed in a unified way as non-linear sigma models possessing a...
Exact Results in N_c=2 IIB Matrix Model (1997)
We investigate N_c=2 case of IIB matrix model, which is exactly soluble. We calculate the partition function exactly and obtain a finite result without introducing any cut-off. We also evaluate some...
Degenerate Double Affine Hecke Algebra And Conformal Field Theory (1997)
Arakawa, T., Suzuki, T., Tsuchiya, A.
We introduce a class of induced representations of the degenerate double affine Hecke algebra of gl_N and analyze their structure mainly by means of intertwiners. We also construct them from modules...
String Field Theory from IIB Matrix Model (1997)
Fukuma, M., Kawai, H., Kitazawa, Y., Tsuchiya, A.
We derive Schwinger-Dyson equations for the Wilson loops of a type IIB matrix model. Superstring coordinates are introduced through the construction of the loop space. We show that the continuum...
A Large-N Reduced Model as Superstring (1996)
Ishibashi, N, Kawai, H, Kitazawa, Y, Tsuchiya, A
A matrix model which has the manifest ten-dimensional $N=2$ super Poincare invariance is proposed. Interactions between BPS-saturated states are analyzed to show that massless spectrum is the same as...

Operator Product Expansion in Two-Dimensional Quantum Gravity (1995)
Aoki, H., Kawai, H., Nishimura, J., Tsuchiya, A.
We consider correlation functions of operators and the operator product expansion in two-dimensional quantum gravity. First we introduce correlation functions with geodesic distances between...

Quantum Gravity and Black Hole Dynamics in 1+1 Dimensions (1992)
We study the quantum theory of 1+1 dimensional dilaton gravity, which is an interesting toy model of the black hole dynamics. The functional measures are explicitly evaluated and the physical state...
Tsuchiya, A., Dolan, P., Shaw, R.
In this paper, we outline the three main concepts of 'ageism'; health maximisation ageism, productivity ageism, and fair innings ageism. We provide a methodological overview of the existing empirical...
QALY maximisation and people's preferences: a methodological review of the literature
Dolan, P., Shaw, R., Tsuchiya, A., Williams, A.
In cost-utility analysis, the numbers of quality-adjusted life years (QALYs) gained are aggregated according to the sum-ranking (or QALY maximisation) rule. This requires that the social value from...
