TL;DR: The oxide superconductors, particularly those recently discovered that are based on La2CuO4, have a set of peculiarities that suggest a common, unique mechanism: they tend in every case to occur near a metal-insulator transition into an odd-electron insulator with peculiar magnetic properties.
Abstract: The oxide superconductors, particularly those recently discovered that are based on La2CuO4have a set of peculiarities that suggest a common, unique mechanism: they tend in every case to occur near a metal-insulator transition into an odd-electron insulator with peculiar magnetic properties. This insulating phase is proposed to be the long-sought “resonating-valence-bond” state or “quantum spin liquid” hypothesized in 1973. This insulating magnetic phase is favored by low spin, low dimensionality, and magnetic frustration. The preexisting magnetic singlet pairs of the insulating state become charged superconducting pairs when the insulator is doped sufficiently strongly. The mechanism for superconductivity is hence predominantly electronic and magnetic, although weak phonon interactions may favor the state. Many unusual properties are predicted, especially of the insulating state.

TL;DR: In this article, the authors postulate that aggression is always a consequence of frustration and indicate manifestations of this sequence in almost every field of human behavior and interpret aggression as assuming many forms and as being affected by other psychological factors.

TL;DR: In this article, an alternative to Maslow's theory and to a simple frustration hypothesis for the problem of relating need-satisfaction to strength of desires is presented. But it does not assume lower-level satisfaction as a prerequisite for the emergence of higher-order needs.

TL;DR: In this paper, the packing configuration of C60 molecules is revealed in an anticlockwise manner around the [111] direction by ∼98° from the ideal Fm3¯ configuration, which is due to an optimized ordering scheme in which electron-rich short inter-pentagon bonds face the electron-poor pentagon centres of adjacent C60 units.
Abstract: STRUCTURAL studies1–.3 of crystalline C60 (ref. 4) have indicated that at room temperature the C60 molecules are orientationally disordered and the crystal structure may be regarded as a face-centred cubic configuration of C60 spheres. Below 249 K, however, the molecules become orientationally ordered3 and a simple cubic lattice results, corresponding to a symmetry change from Fm3¯ to Pa3¯. Here we present the results of a neutron powder diffraction study of the low-temperature ordered structure, which reveals the packing configuration of the C60 molecules. The C60 units are rotated in an anticlockwise manner around the [111] direction by ∼98° from the ideal Fm3¯ configuration. This apparently arbitrary rotation in fact results from an optimized ordering scheme in which electron-rich short (1.391-A) inter-pentagon bonds face the electron-poor pentagon centres of adjacent C60 units. The high symmetry of the C60 molecule allows these interactions to be optimized identically for all twelve nearest neighbours, a possibility that is by no means intuitively obvious. The bonds common to a given pentagon are somewhat longer (1.455 A). The high degree of bonding optimization and the absence of bonding frustration accounts for the high ordering temperature of 249 K (ref. 5).
