      <title>A Particle Structure with Spatial Frequencies, and a Possible Hollow Mass</title>
      <link>http://popups.lib.uliege.be/1373-5411/index.php?id=2821</link>
      <description>In our previous paper, plane waves of any free massive particle were described with a transversal distribution that is defined by a new quantum number, the Bessel order β, which shows the possibility of a hollow structure. The present paper will consider any free massive particle with spherical waves described by their radial distribution. The scale of different Bessel orders is defined and the properties and structure of the presence density are given. Then it is deduced that particles can have a hollow mass and can be made passive with an inefficient crosssection. Finally, an application to Cosmology is proposed and it is suggested that antimatter of extremely high Bessel orders, in galaxy bulge and in star nucleus, may be a solution to the three problems of galaxy stability, dark matter and antimatter in the Universe. </description>

      <title>Cognition</title>
      <link>http://popups.lib.uliege.be/1373-5411/index.php?id=1282</link>
      <description>The integration between psychological concepts and neurophysiological data pose many epistemic difficulties which create almost unsolvable problems. We used the strategy of reconsidering experimental data and theoretical concepts within the frame of reference of some concepts from Quantum Physics and Chemistry. The model of a particle in a box against a potential barrier proved to be adequate to describe and interpret behavioural data from a neurophysiological viewpoint. Concerning cognitive processes we used the model of atom orbitals and of isolobal fragments to build a model of information processing in the frequency domain. After examining some problems related to anticipation, hypothesis construction and transformation we tested experimentally some of these ideas. Analysis of EEG records using Lee method of cross-correlation with Dirac delta waves repeated periodically yields distinctive spatial distributions of patterns of periodic waveforms for cognitive-affective states- joy, sadness, anxiety, anger and mistrust. It was possible, using exclusively electrophysiological indicators in the frequency domain, to classify adequately a group of 35 subjects that experienced these five cognitive-affective states. </description>
