Universal bounds on charged states in 2d CFT and 3d gravity [PDF]
Journal of High Energy Physics, 2016 We derive an explicit bound on the dimension of the lightest charged state in two dimensional conformal field theories with a global abelian symmetry. We find that the bound scales with c and provide examples that parametrically saturate this bound.

Quantization and the Issue of Time for Various Two-Dimensional Models of Gravity
, 1993 It is shown that the models of 2D Liouville Gravity, 2D Black Hole- and $R^2$-Gravity are {\em embedded} in the Katanaev-Volovich model of 2D NonEinsteinian Gravity.

Advanced Biology, EarlyView.Using supramolecular monomers, various hydrogel culture systems were formulated to culture protoplasts; including 2D, 2.5D, and 3D hydrogels. Depending on the culture platform, bioactive functionalization led to protoplast enlargement (2D and 2.5D) or plasmolysis (3D). This work shows the potential to modularly engineer synthetic platforms for cellular

Performance evaluation of HY-2 series satellites in marine gravity field recovery
Geodesy and GeodynamicsChina has successfully launched four Haiyang-2 (HY-2) series altimetry satellites. HY-2A has attracted significant attention in gravity field recovery, but the performance of other HY-2 series satellites, including HY-2B/C/D, is seldom discussed.

Advanced Engineering Materials, EarlyView.This work applies High‐Speed Nanoindentation to study multi‐material transitions in powder bed fusion–electron beam melting components. The aim is to assess the mechanical gradients and interfacial behavior between American iron and steel institute 316L stainless steel and V4E tool steel in additively manufactured structures.

Blocking of Dynamical Triangulations with Matter [PDF]
, 1996 We use the recently proposed node decimation algorithm for blocking dynamical geometries to investigate a class of models, with central charge greater than unity, coupled to 2D gravity.

COSMOLOGICAL SOLUTIONS IN 2D POINCARÉ GRAVITY [PDF]
International Journal of Modern Physics D, 1994 The 2D model of gravity with zweibeins ea and the Lorentz connection one-form [Formula: see text] as independent gravitational variables is considered. The solutions of classical equations of motion which can be interpreted as cosmological ones are studied.

Advanced Engineering Materials, EarlyView.Sludge phases with brittle fracture behavior form in AlMgSi alloys with high concentrations of alloying elements and negatively influence their ductility. The phase type mainly depends on the Si content and the concentration of minor alloying elements like Fe, Mn, Cr, and Mo strongly influences the number of sludge particles. The need for sustainable

2D gravitational Mabuchi action on Riemann surfaces with boundaries
Journal of High Energy Physics, 2017 We study the gravitational action induced by coupling two-dimensional non-conformal, massive matter to gravity on a Riemann surface with boundaries. A small-mass expansion gives back the Liouville action in the massless limit, while the first-order mass ...

Entanglement between two evaporating black holes
Journal of High Energy Physics, 2022 We study a thermo-field double type entangle state on two disjoint gravitating universes, say A and B, with an eternal black hole on each. As was shown previously, its entanglement entropy of the universe A is computed by the generalized entropy on a new
