Preformed Pairs, SU(2) Slave-boson Theory, and High T_c Superconductors
A preformed-pair model was considered. The quantum disordered phase of the d-wave superconducting state was obtained by turning on an

Probing dissociation of space-like photons in deep-inelastic lepton-nucleon scattering
It is shown that the hadronic dissociation of space-like $(Q^2>0)$ photons can be directly probed by performing measurements in the

Quantification of Sleep Fragmentation Through the Analysis of Sleep-Stage Transitions
We introduce new quantitative approaches to study sleep-stage transitions with the goal of addressing the two following questions: (i) Can

Quantum Phases of the Shastry-Sutherland Antiferromagnet
We study possible paramagnetic phases of antiferromagnets on the Shastry-Sutherland lattice by a gauge-theoretic analysis of fluctuations in a theory

Question answering: from partitions to Prolog
We implement Groenendijk and Stokhof's partition semantics of questions in a simple question answering algorithm. The algorithm is sound, complete,

Relation between Magnitude Series Correlations and Multifractal Spectrum Width
We study the correlation properties of long-range correlated time series, $x_i$, with tunable correlation exponent and built-in multifractal properties. For

Spin excitations under fields in an anisotropic bond-alternating quantum S=1 chain: contrast with Haldane spin chains
Inelastic neutron scattering experiments on the S=1 quasi-one-dimensional bond-alternating antiferromagnet Ni(C9D24N4)(NO2)ClO4 have been performed under magnetic fields below and above
