Enhanced Separation Behavior of Metals from Simulated Printed Circuit Boards by Supergravity
Metals, 2022 Printed circuit boards (PCBs) contain valuable metals, epoxy resin, and glass fiber, resulting in them being considered as attractive secondary sources of metals.

Local Symmetries in the AdS_7/CFT_6 Correspondence [PDF]
, 1999 It is shown that local symmetry transformations of the maximal AdS supergravity in seven-dimensional anti de Sitter space induce those of the N=(2,0) conformal supergravity on the six-dimensional boundary at infinity.

Supersymmetric AdS Solitons, Ground States, and Phase Transitions in Maximal Gauged Supergravity
Particles, 2023 We review some recent soliton solutions in a class of four-dimensional supergravity theories. The latter can be obtained from black hole solutions by means of a double Wick rotation.

Special Geometry and Space-time Signature [PDF]
, 2017 We construct N=2 four and five-dimensional supergravity theories coupled to vector multiplets in various space-time signatures (t,s), where t and s refer, respectively, to the number of time and spatial dimensions.

Multi-Field versus Single-Field in the Supergravity Models of Inflation and Primordial Black Holes
Universe, 2021 We review the models unifying inflation and Primordial Black Hole (PBH) formation, which are based on the modified (Starobinsky-type) supergravity. We begin with the basic (Starobinsky) inflationary model of modified gravity and its alpha-attractor-type ...

Physical Review Letters, 2022 Minimal massive gravity in three dimensions propagates a single massive spin-2 mode around an AdS vacuum. It is distinguished by allowing for vacua with positive central charges of the asymptotic conformal algebra and a bulk graviton of positive energy.

On the Geometric Approach to the Boundary Problem in Supergravity
Universe, 2021 We review the geometric superspace approach to the boundary problem in supergravity, retracing the geometric construction of four-dimensional supergravity Lagrangians in the presence of a non-trivial boundary of spacetime.

Renormalization Group Flows from Five-Dimensional Supergravity [PDF]
, 1999 The use of gauged ${\cal N} = 8$ supergravity as a tool in studying the AdS/CFT correspondence for ${\cal N} = 4$ Yang-Mills theory is reviewed. The supergravity potential implies a non-trivial, supersymmetric IR fixed point, and the flow to this fixed ...

Space biomedicine‐oriented bioink and biomimetic blood‒brain barrier
VIEW, EarlyView.Bioinks and bioprinting play a pivotal role in the successful delivery of cell models and the fabrication of tissue models for space biomedicine research. This study investigated the effects of hypergravity and vibration on two‐dimensional adherent cells and three‐dimensional embedded cells and provided methods for storing hybrid bioink and high ...
