1 Preface Preface his master thesis demonstrates the realization of a 2 2 heterodyne receiver array at 1.4 THz based on superconducting hot electron bolometer (HEB) mixers and a Fourier phase grating local oscillator (LO). This is the first time to build a heterodyne receiver array based on these two techniques at such a high frequency. The theoretical(More)
BACKGROUND Human enterovirus 71 (HEV71) causes outbreaks of life-threatening diseases throughout the world. The genesis of these severe diseases is unknown. METHODS During an outbreak of HEV71 infection, we investigated risk factors for critical illness. We developed a modified pediatric index of mortality (mPIM) incorporating heart rate, temperature,(More)
BACKGROUND We compared the antibody response to Haemophilus influenzae type b capsular polysaccharide (PRP) after three doses of a diphtheria toxoid, tetanus toxoid and acellular pertussis vaccine (DTaP) combined with a PRP-tetanus conjugate (PRP-T) in infants randomized to receive oral polio vaccine (OPV) or inactivated polio vaccine (IPV). The polio(More)
