Warping functions of some warped products
Journal of Mathematical Analysis and Applications, 2014 Abstract In this paper we study the warping functions of some warped products. Let H n be the n-dimensional hyperbolic space with sectional curvature −1. We prove that if the warping function f of the warped product H n × f R has a critical point, then H n × f R = H n + 1 if and only

Dielectric Barrier Discharge Electrothermal Heating and Additive Manufacturing of Thermoset Parts
Advanced Materials Technologies, EarlyView.3D printing of thermosets is difficult due to the low yield stress of most uncured resins. However, by locally heating resin using a non‐equilibrium plasma, layers can be partially cured and printing enabled. Plasma application to a liquid epoxy/carbon nanotube composite is observed to cause rapid surface heating and oxidation of the cured layers ...

String Phenomenology 2003, 2004 Warped supergravities with lower-dimensional branes provide consistent field-theoretic framework for discussion of important aspects of modern string theory physics. In particular, it is possible to study reliably supersymmetry breakdown and its transmission between branes.

Dual‐Wavelength Vat Photopolymerization With Dissolvable, Recyclable Support Structures
Advanced Materials Technologies, EarlyView.Selective solubility vat photopolymerization (SSVP) uses a single resin to produce dissolvable thermoplastics and insoluble thermosets in a single 3D print. Wavelength‐selective curing and thermal post‐processing provide 3D spatial control over dissolution kinetics, enabling dissolvable support structures and programmable dissolution profiles.
