The rate-dependent compressive response and resulting fragmentation characteristics of dry ox cortical bone and cyanoacrylate-based cortical bone surrogate material was investigated in two material orientations. Tests were conducted under quasi-static (10−3 s−1) and dynamic (103 s−1) loading in...

[...] withdrawals would be based on the stock of assets in the fund, which depend on contributions from all previous years. Since this stock is unlikely to change much from year to year, withdrawals from the fund would be quite stable.

The surging demand for energy and staggering pollutants in the environment have geared the scientific community to explore sustainable pathways that are economically feasible and environmentally compelling. In this context, harnessing solar energy using semiconductor materials to generate charge...

Management of invasive species and pathogens requires information about the traffic of potential vectors. Such information is often taken from vector traffic models fitted to survey data. Here, user-specific data collected via mobile apps offer new opportunities to obtain more accurate estimates...

Nine ecosystem process models were used to predict CO2 and water vapor exchanges by a 150-year-old black spruce forest in central Canada during 1994-1996 to evaluate and improve the models. Three models had hourly time steps, five had daily time steps, and one had monthly time steps. Model input...

Abstract Boron is a quintessential crustal element but its conspicuous presence in diamond – a mantle mineral – raises questions about potential subduction pathways for boron and other volatiles. It has been a long-standing goal to characterize the isotopic composition of boron in blue,...

Boundary objects (BOs) are abstract or physical artifacts that exist in the liminal spaces between adjacent communities of people. The theory of BOs was originally introduced by Star and Griesemer in a study on information practices at the Berkeley Museum of Vertebrate Zoology but has since been...

This study contrasted two hypotheses theorizing the role of the global shape of a boundary in object location memory. People differentiate reference points based on the global shape extracted from the environment configuration and choose appropriate parts for encoding a specific location....

This paper presents a critical state constitutive model for cemented sand. The model uses a single capped yield surface as a function of the void ratio, confining pressure, preconsolidation pressure, and stress ratio at the peak of the undrained effective stress path. To model the cemented...
