Architecture and Metamorphosis [PDF]

, 2013
When compared to other conserved housekeeping protein families, such as ribosomal proteins, during the evolution of higher eukaryotes, aminoacyl-tRNA synthetases (aaRSs) show an apparent high propensity to add new sequences, and especially new domains. The stepwise emergence of those new domains is consistent with their involvement in a broad range of ...

Metal‐Ion Regulated Light‐Free Z→E Isomerization of Azobenzene Glycomacrocycle

Chemistry – A European Journal, EarlyView.
Metal ion‐catalyzed Z→E isomerization of photoswitchable azobenzene glycomacrocycle: A new azobenzene‐based glycomacrocycle is capable of forming a 1:1 complex with divalent metal ions in both E‐ and Z‐isomers. The complexes undergo light‐free Z→E isomerization in a timescale spanning from seconds to weeks.

Nitric oxide is not a negative regulator of metamorphic induction in the abalone Haliotis asinina

Frontiers in Marine Science, 2014
Nitric oxide (NO) is a second messenger molecule synthesized by the enzyme nitric oxide synthase (NOS) that requires the molecular chaperone heat shock protein 90 (HSP90) for normal enzymatic activity.

Advancing mine pillar design: Evaluating traditional methods and integrating AI for enhanced stability of pillars in the Great Dyke, Zimbabwe

Deep Underground Science and Engineering, EarlyView.
B1 is bord width 1, B2 is bord width 2, L is the pillar length, W is the pillar width, red color and letter A represent the pillars, and white color and number 1 represent excavated areas. Pstress is the average pillar stress; σv is the vertical component of the virgin stress, MPa; and e is the areal extraction ratio. e = B o B o + B P ${\rm{e}}=\frac{{

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

World's fastest 10 000‐m breakthrough: The XY‐22 well redefines deep‐earth access in the Tarim Basin

Deep Underground Science and Engineering, EarlyView.
The Tarim Basin in northwestern China hosts one of the world's deepest petroleum systems, exemplified by the XY‐22 ultra‐deep well (bottom depth: 11 116 m; ~220°C, ~145 MPa). This study integrates tectonic mapping, geological cross‐sections, ultraviolet fluorescence microscopy, and optical photothermal infrared (OPTIR) spectroscopy to characterize ...

Embryonic development of the Mediterranean starfish Hacelia attenuata

Developmental Dynamics, EarlyView.
Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...
