Understanding the complex phase diagram of uranium: the role of electron-phonon coupling

, 2010
We report an experimental determination of the dispersion of the soft phonon mode along [1,0,0] in uranium as a function of pressure. The energies of these phonons increase rapidly, with conventional behavior found by 20 GPa, as predicted by recent ...

The nest as fortress: defensive behavior of Polybia emaciata, a mud-nesting eusocial wasp [PDF]

Journal of Insect Science, 2002
The swarm-founding wasp Polybia emaciata is unusual among eusocial Vespidae because it uses mud, rather than wood pulp, as its primary nest construction material. Polybia emaciata nests are more durable than similarly sized paper nests. We tested the hypothesis that the defensive behavior of this wasp may have been modified to take advantage of their ...

Tailored Hierarchical Porous Copper Architectures via Three Dimensional Printing and Pressure‐less Sintering for Next‐Generation Lithium‐Metal Batteries

Advanced Engineering Materials, EarlyView.
A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.

13: MOVEMENTS, BEHAVIOR, AND NESTING ECOLOGY OF THE WILD TURKEY IN EASTERN ALABAMA*

Wildlife Society Bulletin, 1973
An ecological study of the eastern wild turkey (Meleagris gallopavo silvestris) was conducted in the Alabama Piedmont during the spring and summer of 1968 and 1969. Fifteen hens were captured, patagium‐tagged, instrumented with 27 MHz radio transmitters,

Differences in Pre-Laying Behavior between Floor-Laying and Nest-Laying Pekin Ducks

Animals, 2019
Floor-laying in commercially farmed Pekin ducks is not well understood. This exploratory study aimed to determine if behavioral differences exist between floor-laying and nest-laying ducks.

Influence of intermartensitic transitions on transport properties of Ni2.16Mn0.84Ga alloy

, 2004
Magnetic, transport, and x-ray diffraction measurements of ferromagnetic shape memory alloy Ni$_{2.16}$Mn$_{0.84}$Ga revealed that this alloy undergoes an intermartensitic transition upon cooling, whereas no such a transition is observed upon subsequent ...

Air‐Pressure–Actuated Vibroacoustic Metamaterial With Tunable Bandgap: Design, Modeling, and Characterization

Advanced Engineering Materials, EarlyView.
This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.

A Fatal Nest Construction: Man-mixed Cement Used by Mud-daubing Wasps

Sociobiology, 2018
Some sphecid wasps apparently show tolerance to urban habitats. However, resilience to man-made environments may have harmful consequences when behavioral errors can lead to ecological traps.

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Reproductive aspects of the Purple-throated Euphonia, Euphonia chlorotica (Aves: Fringillidae) in southeastern Brazil, and first record of the species nesting inside a vespiary

Zoologia (Curitiba), 2017
Despite the fact that E. chlorotica (Linnaeus, 1766) is common and widely distributed in South America, the reproductive aspects of the species are poorly documented. Here we present data on 18 active nests found from August to February, between 2007 and
