Analysis of attitude adjustment for airborne drilling rig of anchor excavator
Gong-kuang zidonghuaThe deployment of the front drilling rig requires a significant amount of time before and after water exploration and drainage operations. Loading advanced drilling equipment on the anchor excavator can reduce equipment deployment time and improve ...

Global well-posedness of the Maxwell-Klein-Gordon equation below the energy norm [PDF]
, 2010 We show that the Maxwell-Klein-Gordon equations in three dimensions are globally well-posed in $H^s_x$ in the Coulomb gauge for all $s > \sqrt{3}/2 \approx 0.866$. This extends previous work of Klainerman-Machedon \cite{kl-mac:mkg} on finite energy data $

Advanced Materials, EarlyView.Benefiting from the precisely anchored zincophilic sites, the ample transport channels with rich redox active sites, and the suppressed hydrogen evolution by the copper (Cu) sites, a highly conjugated robust Cu‐Phthalocyanine covalent organic framework layer is designed and applied for directional modulation of zinc (Zn) ions and dendrite‐free Zn ...

Advanced Materials, EarlyView.A covalent adaptable network with dynamic disulfide bonds (DS‐CAN) can rearrange its molecular topology through heating or UV irradiation. When combined with ferromagnetic particles, its photoresponsiveness at room temperature enables contactless, spatiotemporal regulation of dynamic bond exchanges during magnetomechanical actuation.

Synthetic Chromatophores for Color and Pattern Morphing Skins
Advanced Materials, EarlyView.Cephalopods use chromatophore organs (muscle‐actuated pigment sacs) to alter their skin color and pattern. Synthetic chromatophores, which closely mimic the mechano‐optical process found in cephalopods using stimuli‐responsive microscale hydrogel actuators, are reported.

Star formation around active galactic nuclei [PDF]
Active galactic nuclei (Seyfert nuclei and their relatives) and intense star formation can both deliver substantial amounts of energy to the vicinity of a galactic nucleus.
