Within an extended Su-Schrieffer-Heeger model including interchain interactions and the Hubbard model, dynamical relaxation of photoexcitations in two coupled conjugated polymer chains is investigated by using a nonadiabatic evolution method. Initially, one photoexcited other chain dimerized ground state. Due to interactions, electron and/or hole can be transferred from chain. For weak coupling, lattice on similar that found isolate single case. With increasing, amplitude distortions...

Photoacoustic imaging (PAI) is an emerging hybrid technology that combines the advantages of optical and ultrasound imaging. Despite its excellent capabilities, PAI still faces numerous challenges in clinical applications, particularly sparse spatial sampling limited view detection. These limitations often result severe streak artifacts blurring when using standard methods to reconstruct images from incomplete data. In this work, we propose improved convolutional neural network (CNN)...

Photoacoustic imaging (PAI) is an emerging noninvasive modality that merges the high contrast of optical with resolution ultrasonic imaging. Low-quality photoacoustic reconstruction sparse data due to spatial sampling and limited view detection a major obstacle popularization PAI for medical applications.

Within a one-dimensional tight-binding model, the dynamic dissociation processes of trions under an external electric field have been investigated using nonadiabatic evolution method. We demonstrate that trion applied is more difficult than in case for either polaron or bipolaron. Considering effect electron-electron interactions, it found on-site Coulomb interactions reduce while nearest-neighbor enhance stability trion. Furthermore, due to competition between and static presents two...

The dominant position of provincial market in China's power structure makes the optimization process resource allocation insufficient and incomplete.

By constructing a regional market, clearing based on optimal cost model supply, loss compensation mechanism design entities can be carried out Pareto-optimized .

Due to Chinese strong support for the development of renewable energy, consumption energy power in current policy most provinces is "guaranteed consumption". Renewable enterprises take advantage this rule adopt high quotation behavior electricity market compet
