Using Hard Constraints for Representing Soft Constraints [PDF]

, 2011
Most of the current algorithms dedicated to the resolution of over-constrained problems, as PFC-MRDAC, are based on the search for a support for each value of each variable taken independently. The structure of soft constraints is only used to speed-up such a search, but not to globally deduce the existence or the absence of support.

Phenomenological Aspects of Heterotic Orbifold Models at One Loop

, 2003
We provide a detailed study of the phenomenology of orbifold compactifications of the heterotic string within the context of supergravity effective theories.

Bio‐Orthogonally Crosslinked Supramolecular Polymer Bottlebrush Hydrogels for Long‐Term 3D Cell Culture

Advanced Functional Materials, EarlyView.
Fibrous benzenetrispeptide (BTP) hydrogels, fabricated via strain‐promoted azide‐alkyne cycloaddition (SPAAC) crosslinking, form robust, bioinert networks. These hydrogels can support 3D cell culture, where cell viability and colony growth depend on the fiber content.

Optimized Hybrid Resource Allocation in Wireless Cellular Networks with and without Channel Reassignment

Journal of Computer Systems, Networks, and Communications, 2010
In cellular networks, it is important to determine an optimal channel assignment scheme so that the available channels, which are considered as “limited” resources in cellular networks, are used as efficiently as possible.

Spatially Tailorable Liquid Crystalline Elastomer Alignment During Digital Light Process 3D Printing

Advanced Functional Materials, EarlyView.
Here, we report the fabrication of 3D printable liquid crystalline elastomer (LCE) structures with spatially tailorable alignment domains within the same layer. This work addresses the long‐standing challenge of preparing complex 3D LCE architectures with patterned functional domains to achieve nonlinear deformations. Fabrication of multi‐domains in 3D

Restricted Bailouts and the Commitment Problem in Federations [PDF]

Standard models of soft budget constraints consider bailouts as pure monetary transfers. However, in practice often additional obligations or restrictions, such as savings goals, are linked to monetary bailouts.

Dense baryonic matter: constraints from recent neutron star observations

, 2014
Updated constraints from neutron star masses and radii impose stronger restrictions on the equation of state for baryonic matter at high densities and low temperatures.
