Isostructural metal-insulator transition in VO2

Abstract: The metal-insulator transition in correlated materials is usually coupled to a symmetry-lowering structural phase transition. This coupling not only complicates the understanding of the basic mechanism of this phenomenon but also limits the speed and endurance of prospective electronic devices. We demonstrate an isostructural, purely electronically driven metal-insulator transition in epitaxial heterostructures of an archetypal correlated material, vanadium dioxide. A combination of thin-film synthesis, structural and electrical characterizations, and theoretical modeling reveals that an interface interaction suppresses the electronic correlations without changing the crystal structure in this otherwise correlated insulator. This interaction stabilizes a nonequilibrium metallic phase and leads to an isostructural metal-insulator transition. This discovery will provide insights into phase transitions of correlated materials and may aid the design of device functionalities.

Individual differences, rereading, and self-explanation: concurrent processing and cue validity as constraints on metacomprehension accuracy.

Abstract: The typical finding of metacomprehension studies is that accuracy in monitoring one’s own level of understanding is quite poor. In the present experiments, monitoring accuracy was constrained by individual differences in both reading comprehension ability and working memory capacity (WMC), but rereading particularly benefited low-ability and low-WMC readers, effectively eliminating the relationship between monitoring accuracy and these reader characteristics. In addition, introducing a self-explanation reading strategy improved the accuracy of all the readers above mere rereading. The observed interaction between individual differences and rereading is interpreted in terms of concurrent-processing constraints involved in monitoring while text is processed, whereas the more general self-explanation effect is interpreted in terms of accessibility of valid, performance-predicting cues.

Age and pattern of the southern high-latitude continental end-Permian extinction constrained by multiproxy analysis

Abstract: Past studies of the end-Permian extinction (EPE), the largest biotic crisis of the Phanerozoic, have not resolved the timing of events in southern high-latitudes. Here we use palynology coupled with high-precision CA-ID-TIMS dating of euhedral zircons from continental sequences of the Sydney Basin, Australia, to show that the collapse of the austral Permian Glossopteris flora occurred prior to 252.3 Ma (~370 kyrs before the main marine extinction). Weathering proxies indicate that floristic changes occurred during a brief climate perturbation in a regional alluvial landscape that otherwise experienced insubstantial change in fluvial style, insignificant reorganization of the depositional surface, and no abrupt aridification. Palaeoclimate modelling suggests a moderate shift to warmer summer temperatures and amplified seasonality in temperature across the EPE, and warmer and wetter conditions for all seasons into the Early Triassic. The terrestrial EPE and a succeeding peak in Ni concentration in the Sydney Basin correlate, respectively, to the onset of the primary extrusive and intrusive phases of the Siberian Traps Large Igneous Province. The continental record of the end Permian mass extinction is limited, especially from high paleolatitudes. Here, Fielding et al. report a multi-proxy Permo-Triassic record from Australia, resolving the timing of local terrestrial plant extinction and the relationship with environmental changes.

The Zung Self-Rating Depression Scale: convergent validity and diagnostic discrimination.

Abstract: This study examined the concurrent validity of the Zung Self-Rating Depression Scale (SDS) in relation to the Depression (D) scale of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and addressed a gap in the literature with respect to diagnostic discrimination. The participants were persons on probation or parole. Although women were more depressed than men on the SDS, gender did not interact with SDS as a predictor in a logistic regression analysis. The SDS was found to be the primary discriminating variable in distinguishing depressed from nondepressed participants. In addition, the SDS contributed significant incremental validity over the D scale and showed greater accuracy in identifying nondepressed individuals.
