The male-specific transplantation antigen, H-Y, causes rejection of male tissue grafts by genotypically identical female mice and contributes to the rejection of human leukocyte antigen-matched male organ grafts by human females. Although first recognized 40 years ago, the identity of H-Y has remained elusive. T cells detect several distinct H-Y epitopes,(More)
Modulation transfer functions (MTFs) were measured with three different psychoacoustical paradigms in the same normal-hearing subjects. In the temporal-probe method, the threshold of a 4-ms probe tone (frequencies of 1000 and 4000 Hz) was measured at various envelope phases within a 100% sinusoidally amplitude-modulated (SAM) noise at modulation frequencies(More)
This paper provides a framework for evaluating and comparing country transport policies to understand the extent to which these are being altered to cope with aging societies. Using the framework, transport policy documents of six countries in the industrialized world were analyzed and compared. A deliberate effort is made in the selection of countries to(More)
Two complement-dependent assays for circulating immune complexes, the C1q-binding assay and the conglutinin binding, were used to study patients with suspected immune-complex disease. Complexes were detected most frequently in multisystem disease such as infective endocarditis (69%) and systemic lupus erythematosus (60%), and less frequently in isolated(More)
We present a power spectral analysis of the Crab pulsar's timing noise, mainly using radio measurements from Jodrell Bank taken over the period 1982-1989, an interval bounded by sparse data sampling and a large glitch. The power spectral analysis is complicated by nonuniform data sampling and the presence of a steep red power spectrum that can distort power(More)
