Neurophysiological findings relevant to echolocation in marine animals
A review of echolocation mechanisms in marine mammals, chiefly porpoises, is given. Data cover peripheral auditory and central neurophysiological specializations favorable to the analysis of echolocating clicks and their echoes. Conclusions show (1) signals are received from 50 up to at least 135 kHz, (2) sound is received through the mandible skin, and (3) the midbrain sites are insensitive to low frequencies (below 6 kHz)
NASA Ames potential flow analysis (POTFAN) geometry program (POTGEM), version 1
A computer program known as POTGEM is reported which has been developed as an independent segment of a three-dimensional linearized, potential flow analysis system and which is used to generate a panel point description of arbitrary, three-dimensional bodies from convenient engineering descriptions consisting of equations and/or tables. Due to the independent, modular nature of the program, it may be used to generate corner points for other computer programs

A critical examination of Paul Tillich’s doctrine of the Holy Spirit
This thesis expounds and analyses Paul Tillich’s doctrine of the Spirit as set out in the third volume of his Systematic Theology and other relevant passages from his writings. After a brief introduction to his theological method , his understanding of God and the symbolic nature of our knowledge of the divine is examined, specific reference being made to the meaning of 'Spirit’ and the Trinitarian symbols. A chapter on the nature of life and its ambiguities in the spheres of morality, culture and religion, with which the doctrine of the Spirit is correlated in Tillich's thought, prepares the way for a more detailed analysis of this doctrine. This analysis deals first with Tillich's understanding of the divine Spirit in relation to the spirit of man, the Spirit's manifestation in the world, and the marks of the Spiritual Presence in historical mankind, culminating in the Christ and the creation of the Spiritual Community. The importance of the Spirit's work in resolving life's ambiguities by means of an unambiguous life of transcendent unity is indicated. The succeeding chapters expand this discussion and deal with the Spirit's impact in the realm of religion, the life of the church and the individual within the church; in the realms of culture and morality, the wider life of society; and finally, in the total context of man's life in the work of healing. A concluding chapter points out the implications of the concept of the transcendent unity of unambiguous life, suggesting that Tillich's understanding of the Spirit significantly deviates from orthodox Christian pneumatology, but also emphasising that in the final analysis Tillich has made a significant contribution to contemporary theological study of the Spirit
Higgs Boson Decays to tau-pairs in the s-channel at a Muon Collider
We study the observability of the \tautau decay mode of a Higgs boson
produced in the -channel at a muon collider. We find that the spin
correlations of the \tautau in decays
are discriminative between the Higgs boson signal and the Standard Model
background. Observation of the predicted distinctive distribution can confirm
the spin-0 nature of the Higgs resonance. The relative coupling strength of the
Higgs boson to and can also be experimentally determined.Comment: to appear in PL

Ad Hoc Selection of Voice over Internet Streams
A method and apparatus for a communication system technique involving ad hoc selection of at least two audio streams is provided. Each of the at least two audio streams is a packetized version of an audio source. A data connection exists between a server and a client where a transport protocol actively propagates the at least two audio streams from the server to the client. Furthermore, software instructions executable on the client indicate a presence of the at least two audio streams, allow selection of at least one of the at least two audio streams, and direct the selected at least one of the at least two audio streams for audio playback
