The B cell activating factor BAFF (BlyS/TALL-1/zTNF4) is a tumor necrosis factor (TNF)-related ligand that promotes B cell survival and binds to three receptors (BCMA, TACI, and the recently described BAFF-R). Here we report an absolute requirement for BAFF in normal B cell development. Examination of secondary lymphoid organs from BAFF-deficient mice(More)
1. In cats either decerebrated and/or anesthetized by various doses of pentobarbital, the action of pinna stimulation (PS) and other natural somatic or electrical nerve stimuli upon respiration was investigated. For an indication of the state of excitability of the reticular formation the lumbar extensor fusimotor PS-responses were obseve simultaneously. 2.(More)
The system description presents the conception and a pro-totypical implementation of a multi-context system, used for computing and implementing temporal modalities within given data without the use of modal operators. Instead, an external constraint based rule system is used for computing the corresponding temporal relations, making use of the way a(More)
Multi-Agent systems follow a highly abstract programming paradigm. Because of this abstraction level, behaviours of the participants are not always clearly reproducible for humans. In this paper, we present a framework that enables agents to do some introspection and describe themselves. Our approach uses Java annotations and JDI, the Java debugging(More)
1. In decerebrate or pentobarbital anesthetized cats the effect of intra-right atrial injection of phenyldiguanide (PDG) upon lumbar fusimotor activity and monosynaptic reflex activity and their responsiveness to pinna stimulation (PS) was investigated. 2. The spontaneous activity of triceps surae muscle spindle afferents or lumbar γ-efferents was in most(More)
