    Notes: Summary Kinetic studies of the uptake of hydroquinone-β-D-glucoside (arbutin) by excised roots of barley demonstrated that this compound is actively transported. Similar studies on the uptake of hydroquinone indicated that the latter compound enters the root tissues by diffusion. A concentration gradient favouring diffusion is maintained for at least three hours by the conversion of the aglucone to its correspondings glucoside. Hydroquinone, at a concentration of 5 mM, reduced uptake of 86rubidium ion by approximately 30%.

    Notes: Abstract We explore the possibilities of a new informal language, applicable to the microdomain, which enables such characteristics as superposition and discreteness to be introduced without recourse to the quantum algorithm. In terms of new notions that are introduced (e.g. ‘potentiation’ and ‘ensemblation’), we show that an experiment need no longer be thought of as a procedure designed to investigate a property of a ‘separately existing system’. Thus, the necessity of a sharp separation between the ‘system under observation’ and the ‘apparatus’ is avoided. Although the new language is very different from that of classical physics, classical notions appear as a special limiting case. This new informal language leads to a mathematical formalism which employs the descriptive terms of a cohomology theory with values in the integers. Thus our theory is not based on the use of a space-time description, continuous or otherwise. In the appropriate limit, the mathematical formalism contains certain features similar to those of classical field theories. It is therefore suggested that all the field equations of physics can be re-expressed in terms of our theory in a way that is independent of their spacetime description. This point is illustrated by Maxwell's equations, which are understood in terms of cohomology on a discrete complex. In this description, the electromagnetic four-vector potential and the four-current can be discussed in terms of an ‘ensemblation’ of discontinuous hypersurfaces or varieties. Since the cohomology is defined on the integers the charge is naturally discrete.

    Notes: Abstract We present results obtained in π− A (A=C, Cu, Pb) — collisions at 38 GeV/c. A single particle trigger selects events with one charged particle in the central region and large transverse momentum. The effect of this trigger on the multiplicities of all charged particles and of protons is shown.

    Notes: Abstract Correlations between charged hadrons are investigated in a 280 GeV muon-proton scattering experiment. Although most of the observed particles are decay products it is shown that the correlations found originate in the fragmentation process and are not due simply to resonance production. Correlations are demonstrated between hadrons close in rapidity with respect to their charges and to the directions of their momentum components perpendicular to the virtual photon axis. Such short range correlations are predicted by the standard hadronization models.

    Notes: Abstract In this paper, we discuss the general significance of order in physics, as a first step toward the development of new notions of order. We begin with a brief historical discussion of the notions of order underlying ancient Greek views, and then go on to show how these changed in key ways with the rise of classical physics. This leads to a broader view of the significance of order, which helps to indicate what is to be meant by a change of our general notions of order in physics. We then go into relativity and quantum theory, showing how these developments actually did bring in further new notions of order, which are however inconsistent and otherwise inadequate in certain ways. Finally, using these inconsistencies and inadequacies as clues or indications for yet a further new concept of order, we make some proposals for novel directions of inquiry (to be discussed in some detail in later papers) which could lead to theories as different from relativity and quantum theory as these are from classical physics.

    Notes: Abstract In this paper, a very close relationship between Prigogine's notions of irreversibility and the implicate order is brought out. Certain of Prigogine's basic assumptions with regard to irreversible processes are also shown to be the equivalent of the introduction of nilpotent operators in the algebra underlying the implicate order.

    Notes: Abstract In this paper, we inquire further into the question of the emergence of new orders in physics, first raised in an earlier paper. In this inquiry, we are led to suggest that the quantum theory indicates the need for yet another new order, which we call “enfolded” or “implicate.” One of the most striking examples of the implicate order is to be seen by considering the function of the hologram, which clearly reveals how a total content (in principle extending over the whole of space and time) is “enfolded” in the movement of waves (electromagnetic and other kinds) in any given region. We then come to the notion that the quantum theory indicates that this implicate order is not merely a dependent or fortuitous feature of the content, but rather, that it should be considered as the independent ground of existence of things, while the ordinary explicate order is what should be considered as dependent. Finally, in the appendix we point out how the implicate order is expressed naturally in terms of an algebra similar to that of the quantum theory, which is, however, subject to generalizations going beyond the limits of what has meaning in this theory. Various new directions of further research are indicated, which will be explained in later papers.

    Notes: Abstract. Relativistic Gamow vectors emerge naturally in a time asymmetric quantum theory as the covariant kets associated to the resonance pole $s=s_R$ in the second sheet of the analytically continued S-matrix. They are eigenkets of the self-adjoint mass operator with complex eigenvalue $\sqrt{s_R}$ and have exponential time evolution with lifetime $\tau = - \hbar/2\mathrm{Im}\sqrt{s_R}$ . If one requires that the resonance width $\Gamma$ (defined by the Breit-Wigner lineshape) and the resonance lifetime $\tau$ always and exactly fulfill the relation $\Gamma=\hbar/\tau$ , then one is lead to the following parameterization of $s_R$ in terms of resonance mass $M_R$ and width $\Gamma_R$ : $s_R = (M_R - i\Gamma/2)^2$ . Applying this result to the $Z$ -boson implies that $M_R \approx M_Z - 26\mbox{MeV}$ and $\Gamma_R \approx \Gamma_Z-1.2\mbox{MeV}$ are the mass and width of the {\it Z}-boson and not the particle data values $(M_Z,\Gamma_Z)$ or any other parameterization of the Z-boson lineshape. Furthermore, the transformation properties of these Gamow kets show that they furnish an irreducible representation of the causal Poincaré semigroup, defined as a semi-direct product of the homogeneous Lorentz group with the semigroup of space-time translations into the forward light cone. Much like Wigner's unitary irreducible representations of the Poincaré group which describe stable particles, these irreducible semigroup representations can be characterized by the spin-mass values $(j,s_R=(M_R-i\Gamma/2)^2)$ .

    Notes: Abstract The multiplicity distributions of charged particles produced from π−,K − and $$\bar p$$ interactions with the nuclei Li, C, S, Cu, CsI, Pb at 40 GeV/c were studied. It was found that the linear relationD=a〈n〉+b is satisfied for the distributions of different kinds of secondary particles including knocked out protons. Consequently, the use of the scaling variablez′=(an+b)/(a〈n〉+b) ensures the scaling of the distributions with respect to the mass numberA at least up to the second moment.
