Virtual bound states elements and their effects on magnetic and electrical properties of Fe-Ni based metal amorphous nanocomposites

Metal amorphous nanocomposite alloys, with compositions (Fe 70 Ni 30 ) 80-x Nb 4 Si 2 B 14 TE x (0 ≤ x ≤ 5), where TE is a transition element, and (Fe 70 Ni 30 ) 80-y Nb 4+y Si 2 B 14 (0.5 ≤ y ≤ 2) were synthesized. Samples were annealed at 440 °C and strain-annealed at 440 °C and 300 MPa. Resistivity was found to increase with small substitutions of TE elements. Increasing V resulted in reduced B s from 1.2 T to 0.5 T. Further Mo additions lowered B s to 0.6 T, and consistently reduced the permeability. For Cr and Nb, resistivity increased, and strain-annealed permeability was lower than the annealed permeability. Finally, toroidal core losses on (Fe 70 Ni 30 ) 79.5 Nb 4 Si 2 B 14 V 1 yielded W1.0/400 = 2.1 W/kg, and W1.0/1 k = 6.0 W/kg.

Zooming in on virtual commutes: Telecommuting impacts on mobility and sustainability

Motivated by a societal shift towards remote work and rapid advancement in information and communication technologies, this study examines the impact of telecommuting on urban mobility across the nine counties of the San Francisco Bay Area, California. Utilizing a behaviorally realistic integrated agent-based transportation model and recent data on telecommuting patterns, we simulate the impact of multiple telecommuting scenarios on transportation system outcomes. This provides a comprehensive picture of the impact of remote work on travel costs and accessibility of all travelers, factoring in changes in mode use and congestion. We analyze how telecommuting influences broader societal factors such as transportation energy consumption. Our findings indicate that increased telecommuting reduces overall person miles traveled and transportation energy consumption. Furthermore, telecommuting results in externality benefits by improving accessibility and reducing commute times for non-telecommuters.
