Coarse-grained reconfigurable architectures (CGRAs) present an appealing hardware platform by providing the potential for high computation throughput, scalability, low cost, and energy efficiency. CGRAs consist of an array of function units and register files often organized as a two dimensional grid. The most difficult challenge in deploying CGRAs is compiler scheduling technology that can efficiently map software implementations of compute intensive loops onto the array. Traditional schedulers

HIFU could be a safe, effective, and noninvasive procedure that can be used to improve facial wrinkles and skin laxity in Asian skin. It is particularly effective for clinical improvement in the jawline, cheek, and perioral areas.

The global challenge of clean water scarcity needs to be confronted with novel sustainable, climate neutral solutions, over the entire spectrum of possible clean water availability. Atmospheric moisture represents a major untapped resource that can be harvested by sorbents, enabling water production in dry inland regions where it is needed. While benefiting from the utilization of an important renewable energy source, solar-driven, sorbent-based atmospheric water harvesting systems are inseparab

A simple method for the formation of multiscale metal patterns is presented using hierarchical polymeric stamps with perfluoropolyether (PFPE). A dual-scale PFPE structure is made via two-step moulding process under partial photocrosslinking conditions. The hierarchical PFPE stamp enables multiscale transfer printing (MTP) of metal pattern in one step within microwells as well as on curved surfaces.

In this paper, we study the small time asymptotic behavior of the spectral heat content Q ∼ D ( α ) ( t ) of an arbitrary bounded C 1 , 1 domain D with respect to the subordinate killed Brownian motion in D via an ( α / 2 ) -stable subordinator. For all α ∈ ( 0 , 2 ) , we establish a two-term small time expansion for Q ∼ D ( α ) ( t ) in all dimensions. When α ∈ ( 1 , 2 ) and d ⩾ 2 , we establish a three-term small time expansion for Q ∼ D ( α ) ( t ) .

In this Letter, an implantable hybrid temperature sensor for use in a micro-scale space in power MEMS devices is proposed. The developed sensor use chrome silicide (CrSi2), which has a very high electromotive force, and nickel as a base metal. Since a thermocouple is an appropriate device to measure temperature at a specific spot, the correlations between the junction sizes and electromotive forces should be verified to reduce the junction size of the thermocouple. Furthermore, it is necessary t

Surface wrinkling is a promising route to control the mechanical, electrical, and optical properties of materials in a wide range of applications. However, previous artificial wrinkles are restricted to single or random orientation and lacks selectivity. To address this challenge, this study presents multidirectional wrinkle patterns with high selectivity and orientation through sequential uniaxial strain with conformal polymeric shadow masks. The conformal but nontraceable polymeric stencil wit
