Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Integrated optimization of urban agglomeration passenger transport hub location and network design

open access: yesEURASIP Journal on Wireless Communications and Networking, 2018
Because of the influence of comprehensive hub construction on network flow, this paper adopts the bi-level programming model (BPM) to solve the problem about the integrated optimization of multi-hub location and network layout.

Multi-period hub location problem: a review

open access: yesRAIRO - Operations Research, 2022
In hub-and-spoke systems, due to the changes in the input parameters affecting the system over time, transportation system providers should make the right and timely decisions about hub facilities. For this reason, multi-period hub location problems are especially important.

Piezo2 Mediates a Vicious Cycle of “Mechanical Homeostasis Imbalance—Inflammation” in Sensory Nerves and the Cartilage Endplate

open access: yesAdvanced Science, EarlyView.
In a lumbar spine instability model, dorsal root ganglion cells mediate the perception of relevant mechanical stresses through Piezo2 and subsequently release CGRP. CGRP activates the NF‐κB signaling pathway in cartilage endplate cells through the receptor RAMP1.

Designing application software in wide area network settings [PDF]

open access: yes, 1990
Progress in methodologies for developing robust local area network software has not been matched by similar results for wide area settings. The design of application software spanning multiple local area environments is examined. For important classes of

Neural Fields for Highly Accelerated 2D Cine Phase Contrast MRI

open access: yesAdvanced Science, EarlyView.
ABSTRACT 2D cine phase contrast (CPC) MRI provides quantitative information on blood velocity and flow within the human vasculature. However, data acquisition is time‐consuming, motivating the reconstruction of the velocity field from undersampled measurements to reduce scan times. In this work, neural fields are proposed as a continuous spatiotemporal

Projecting the flow variables for hub location problems [PDF]

open access: yesNetworks, 2004
AbstractWe consider two formulations for the uncapacitated hub location problem with single assignment (UHL), which use multicommodity flow variables. We project out the flow variables and determine some extreme rays of the projection cones. Then we investigate whether the corresponding inequalities define facets of the UHL polyhedron.
