Single-band and Dual-band Beam Switching Systems and Offset-fed Beam Scanning Reflectarray
… capability. Beam scanning capability and multi-band operation of the microstrip reflectarray have been main research topics in the reflectarray design. Narrow bandwidth of the reflectarray is the main obstacle for the various uses of the reflectarray. The wideband antenna element with a large …

Bistable prestressed spring steel grippers for aerial perching and grasping
… through the use of prestressed spring steel bands (PSSB) to create compliant bistable grippers for aerial perching and grasping. We investigate multiple different PSSB configurations. We first investigate two single PSSB gripper designs, a single band gripper with a cable driven opening …

Analytical and simulation models for flexible, robotic automotive assembly lines
… to analyze the throughput of the new layout in a single band and two bands with a finite buffer. The simulation results show that the new layout achieves an average of 25.6% and 35.9% speed up over the conventional layout for the single band and two bands cases respectively. We improve previous …

Practical realisation of multiband planar filters on multilayer substrates
… specified essential requirements such as multi-band operation, compact size, and without significant deteriorated filter performance in comparison with single-band filters. The focus is placed on new synthesis and design procedures for multiband responses. In some cases, the possibility to …

Regulation of Adenylate Kinase
… the adenylate kinase-associated protein gave a single band on a sodium dodecyl sulfate-polyacrylamide gel with M(,r) = 34,000. The interaction of this protein with adenylate kinase explains why the thermolability of the mutant adenylate kinase changed during purification and the dependence of …

MULTI-BAND BOSE HUBBARD MODELS AND EFFECTIVE THREE-BODY INTERACTIONS
… study diverse quantum many-body Hamiltonians. A single-band Bose-Hubbard (BH) Hamiltonian was first proposed to describe these systems in 1998 and its associated quantum phase-transition was subsequently observed in 2002. Over the years, there has been a rapid progress in experimental …

Analysis of deformation bands in the Aztec Sandstone, Valley of Fire State Park, Nevada
Deformation bands were analyzed by mapping and describing over 500 of the structures exposed on a bedding surface of about 560 square meters present in the Aztec Sandstone in the Valley of Fire State Park, Nevada; Three sets of deformation bands are present. Two sets are interpreted as coeval and …

Antenna Multi-Band Enhancement by Employing Negative Impedance Converters
… centered at 2.9 GHz, to create a multi-band network. The network exhibits resonances at frequencies of 0.9 GHz, 1.5 GHz and 1.9 GHz. The work highlights the design process of pairing a NIC with a capacitive, single-band antenna, addressing key challenges such as overcoming the …

Optimal Sum-Rate of Multi-Band MIMO Interference Channel
… in the same area and occupy the same frequency band(s). The performance of these wireless systems is coupled to each other due to the mutual interference. One such wireless scenario is modeled as a network of simultaneously communicating node pairs and is generally referred to as an interference …

Time-dependent adjoint-based optimization of photonic crystals and metamaterials using a stabilized finite element method
… photonic crystals is due to their use as multi-band optical waveguides for telecommunication applications. For this design optimization, to ensure smooth surfaces, Bezier curves are employed to parametrically represent the shape. To reflect the design changes on the mesh, linear elasticity is …

Investigation of catalase and superoxide dismutase from Mycobacterium avium, M. intracellulare and M. scrofulaceum
… of crude extracts demonstrated two bands of catalase activity in both M. avium and M. intracellulare extracts and four bands of activity in M. scrofulaceum extracts. These bands differed in their susceptibility to heat inactivation and inhibition by 3-amino-1,2,4-triazole. M. …
