Time-Dependent Open String Solutions in 2+1 Dimensional Gravity

, 1993
We find general, time-dependent solutions produced by open string sources carrying no momentum flow in 2+1 dimensional gravity. The local Poincar\'e group elements associated with these solutions and the coordinate transformations that transform these ...

Identification and Characterization of an In Silico Designed Membrane‐Active Peptide with Antiviral Properties

Advanced Science, EarlyView.
An evolutionary molecular dynamics platform is used to design P1.6, a membrane‐active peptide that senses lipid packing defects in viral envelopes. P1.6 adopts a stabilized α‐helical structure upon membrane contact, disrupts virus‐like liposomes, and damages HIV‐1 particles.

Active earth pressure calculation method for gravity retaining wall of railway subgrade based on discretized potential sliding surface inclination angle

Yantu gongcheng xuebao
The cross-section of the backfill behind railway subgrade gravity retaining walls is trapezoidal, and the backfill is subjected to train loads. General formulas of Coulomb earth pressure theory are not applicable for the determination of the location of ...

Monopoles and Holography

, 2010
We present a holographic theory in AdS_4 whose zero temperature ground state develops a crystal structure, spontaneously breaking translational symmetry. The crystal is induced by a background magnetic field, but requires no chemical potential.
