What the Government Purchases Multiplier Actually Multiplied in the 2009 Stimulus Package [PDF]

open access: yes
Much of the recent economic debate about the impact of stimulus packages has focused on the size of the crucial government purchases multiplier. But equally crucial is the size of the government purchases multiplicand—the change in government purchases ...

Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays

open access: yesAdvanced Functional Materials, EarlyView.
Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.

Dynamic modeling of spatial parallel mechanism with multi-spherical joint clearances

open access: yesInternational Journal of Advanced Robotic Systems, 2019
The parallel mechanism has advantages of the high speed, high precision, strong carrying capacity, and high structural rigidity. Most of the previous studies concerning the dynamic modeling focused on planar mechanisms with revolute clearance joints or ...

Architectural Tuning of Bouligand Electrospun Laminates Enables Coupled Mechanical Robustness and Electromechanical Sensing

open access: yesAdvanced Functional Materials, EarlyView.
Bioinspired Bouligand architectures are translated into biodegradable polymer laminates with integrated sensing, revealing how structural design governs multifunctional performance. A 20° interlayer rotation optimizes strength, flexibility, and electromechanical response, while embedded nanotube networks enable real‐time damage detection and wearable ...

Voltage Gated Ion Entry Into Two‐dimensional Angstrom‐Scale Channels

open access: yesAdvanced Functional Materials, EarlyView.
We demonstrate voltage‐gated ion transport through artificial Å‐scale slit channels (∼4 Å high) formed by van der Waals assembly of 2D materials. At low electric fields, ions are excluded while water permeates. Above a threshold voltage, nonlinear hysteretic conduction emerges, driven by ion dehydration and concentration‐dependent barriers, mimicking ...

Spatiotemporal squeeze-and-excitation residual multiplier network for video action recognition

open access: yesTongxin xuebao, 2019
Aiming at the shortcomings of shallow networks and general deep models in two-stream network structure,which could not effectively learn spatial and temporal information,a squeeze-and-excitation residual network was proposed for action recognition with a

A Multiplier Based on the Algorithm of Chinese Abacus

open access: yes, 2012
[[abstract]]A 4x4 and 8x8 bit multiplier is demonstrated based on the Chinese abacus. As comparing the simulation result of this work with the speed of the 4x4 and 8x8 bits Braun array multiplier, the delays of the 8-bit abacus multiplier are 14% and 7.5%
