Packing rates of measures and a conjecture for the packing density of 2413

, 2010
We give a new lower bound of 0.10472422757673209041 for the packing density of 2413, justify it by a construction, and conjecture that this value is actually equal to the packing density. Along the way we define the packing rate of a permutation with respect to a measure, and show that maximizing the packing rate of a pattern over all measures gives ...

Densification behavior of ceramic tritium breeder pebble beds under vertical vibration: Effect of vibration parameters

Nuclear Materials and Energy
Packing density of the tritium breeder pebble beds are closely related to the effective density of the lithium atom in the breeding cavities. And the higher the density of lithium atoms the higher the tritium breeding ratio.

Estuarine community response to longline spacing in intertidal oyster culture

Aquaculture Environment Interactions
Structures on which oysters are cultured can have negative effects on other habitats such as seagrass. Intertidal longlines hold clusters of oysters above the sediment surface but may influence the light, hydrodynamics, or desiccation environment for ...

Flexible, Transparent and Conductive Metal Mesh Films with Ultra-High FoM for Stretchable Heating and Electromagnetic Interference Shielding

Nano-Micro Letters
Highlights A transparent, conductive, and flexible metal mesh film has been developed by a low-cost, uniform self-forming crackle template and electroplating strategy. The Cu mesh films show an ultra-low sheet resistance (0.18 Ω □−1), high transmittance (

Master Sintering Curve for TiO2

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017
The master sintering concept is introduced as a unifying sintering model for the initial, intermediate and final stage of sintering. The master sintering curve is independent on the time-temperature trajectory due to account for its integral. The master

Vicinal combination of N—NH2 and C—NO2 benefitting for low sensitivity and high energy azole molecules: A strategy developed from isomerization

Energetic Materials Frontiers
It is nowadays challenging to create low sensitivity and high energy molecules (LSHEMs), largely restricted by the high complexity and difficult interpretation of composition-structure-property relationships of energetic materials.
