BRIGHT Enables High‐SNR Live‐Cell Imaging of Non‐Repetitive Sequences via Bivalent Fluorescent Nanobody‐Mediated Cascade‐Dependent Illumination

Advanced Science, EarlyView.
BRIGHT is a newly developed live‐cell imaging system that integrates cascade amplification with background denoising through the bivalent binding capability and antigen‐dependent stability of a bivalent fluorescent nanobody targeting ALFA peptides.

The Adaptive Physical Activity Study in Stroke (TAPAS): A Feasibility Sequential Multiple Assignment Randomized Trial

Advanced Science, EarlyView.
This study examines the feasibility of a mobile health physical activity intervention for individuals post‐stroke using a sequential multiple assignment randomized trial (SMART) design. High recruitment, retention, and adherence rates are observed, with promising trends in step count, fatigue, and quality of life.

Novel Optoelectronic Reconfigurable Transistors Based on Graphene/VO2 Heterojunction for Efficient Neuromorphic Perception, Computation, and Storage

Advanced Science, EarlyView.
A novel optoelectronic reconfigurable neuromorphic transistor based on a graphene/VO2 heterojunction with inserted Au electrodes is proposed. It exhibits broad‐spectrum self‐powered photodetection capability ranging from 365 to 940 nm. Through bias control and electrode sizing strategies, multiple functions for switch, synapse, and storage are achieved,

Highly Efficient Discovery of 3D Mechanical Metamaterials via Monte Carlo Tree Search

Advanced Science, EarlyView.
Machine learning (ML), as a data‐driven method, has revolutionized metamaterial design, surpassing traditional intuition‐driven trial‐and‐error methods in both efficiency and performance. Here, MCTS‐AL, an active learning framework integrating finite element simulation (FEM), convolutional neural networks (CNNs), and Monte Carlo Tree Search (MCTS ...

The Power of Dynamic Asset Allocation

The Journal of Portfolio Management, 2014
This article re-assesses the evidence and practical relevance of asset returns’ long-horizon predictability, investigating whether practitioners can profitably exploit predictability patterns by using relatively simple, dynamic asset allocation strategies.

Optimal Reactive Power Allocation

IEEE Transactions on Power Systems, 1987
A systematic procedure is developed to locate reactive power devices in a power system based on a set of indices, that are based on overall system conditions. After identifying the desired locations, the cost of installation and number of reactive power devices, subject to any required practical and real economic constraints, are minimized.

Power Allocation for Cooperative Communications

2010
In this chapter, we review the optimal power allocation policies for fading channels in single user and multiple access scenarios. We provide some background on cooperative communications, starting with the relay channel, and moving onto mutually cooperative systems.

Power allocation for interference channels

2013 National Conference on Communications (NCC), 2013
We propose power allocation algorithms for increasing the sum rate of two and three user interference channels. The channels experience fast fading and there is an average power constraint on each transmitter. Our achievable strategies for two and three user interference channels are based on the classification of the interference into very strong ...

Hierarchical Power Allocation Games

2011
In this chapter, we look at the key issue of power allocation (PA) where the target is the competitive maximization of the information throughput sustained by each link over the network. More specifically, we focus on the concept of hierarchy which exists between different radios/systems sharing the same resources.

The exchange and allocation of decision power

Theory and Decision, 1992
Traditional theories of multi-person choice takes as exogenous data the allocation of decision power, that is, they assume the answer to the question of who-decides-what. This paper applies the standard economic theory of scarce resource allocation to explain observed allocations of decision power using as an illustrative example the allocation of ...
