Homo erectus was the first human lineage to disperse widely throughout the Old World, the only hominin in Asia through much of the Pleistocene, and was likely ancestral to H. sapiens. The demise of this taxon remains obscure because of uncertainties regarding the geological age of its youngest populations. In 1996, some of us co-published electron spin resonance (ESR) and uranium series (U-seri...

counties (Torrent et al., 1980), and in soils formed in late The morphologic development of soils on marine terraces is a function of terrace age and geomorphic evolution. In this study, inter­ relationships between terrace landscape evolution and pedogenic sil­ ica cementation were investigated. Soil morphology, micromorphol­ ogy, selective dissolution, penetration resistance, and hydraulic co...

Exploring the chemical reactivity of different atomic sites on crystal surface and controlling their exposures are important for catalysis and renewable energy storage. Here, we use two-dimensional layered molybdenum disulfide (MoS2) to demonstrate the electrochemical selectivity of edge versus terrace sites for Li-S batteries and hydrogen evolution reaction (HER). Lithium sulfide (Li2S) nanopa...

Composite samples of freshly voided excreta from 91 poultry houses were tested qualitatively for Salmonella; 26 (29%) were positive. The houses were located on 36 farms, 18 of which (50%) yielded one or more positive samples. In a separate, quantitative study, Salmonella densities ranged from less than 1 to over 34,000 per g of excreta (dry weight). High densities were noted in waste from cage ...

We present the development and application of small buoy systems for wave energy harvesting (free-floating or slackly moored), to produce about 1 KW per unit at full scale. These systems are targeted for powering distributed marine surveillance and instrumentation networks, and should be simple in concept, easily deployable, storm resilient, and low maintenance. Our work involved design, experi...

Density functional theory is used to explore the energy landscape of Pd atoms adsorbed on the terrace of MgO(100) and at oxygen vacancy sites. Saddle point finding methods reveal that small Pd clusters diffuse on the terrace in interesting ways. The monomer and dimer diffuse via single atom hops between oxygen sites with barriers of 0.34 eV and 0.43 eV respectively. The trimer and tetramer, how...

This study measures the uplift rates of a flight of marine terraces along the Glenafric coastal region of the South Island of New Zealand, which will provide a context for how local fold growth in the North Canterbury fold and thrust belt (NCFTB) contributes to local uplift rates. Several methods were used to measure uplift rate of the marine terraces: 1) collecting shell samples for AAR dating...

The fabless integrated circuit (IC) design is one of the most important sectors of the semiconductor industry. In 2010, the total revenue of the fabless IC design sector had already hit US$59.6 billion, accounting for one-fifth of the total semiconductor industry revenue. Thus, understanding the efficiency of fabless IC design houses is critical not only for managers of fabless IC design houses...
