Controlling the movement of nanoparticles in a dielectric metasurface by using rotatable linearly polarized light.

We propose a nanoparticle transportation method in a dielectric metasurface for nanoparticles of particular sizes using rotatable linearly polarized light. The dielectric metasurface utilizes plum-blossom structures to realize hot spot position switching by rotating the polarization state of incident light. The convex point of the plum-blossom dielectric metasurface always has a hot spot with higher intensity than that in the concave point, and there is an unbalanced potential well between the two adjacent plum-blossom dielectric metasurface units so that the nanoparticles are more easily attracted and transferred to the adjacent unit with a deeper potential well.

RT-RCG: Neural Network and Accelerator Search Towards Effective and Real-time ECG Reconstruction from Intracardiac Electrograms.

There exists a gap in terms of the signals provided by pacemakers (i.e., intracardiac electrogram (EGM)) and the signals doctors use (i.

SmartDeal: Remodeling Deep Network Weights for Efficient Inference and Training.

The record-breaking performance of deep neural networks (DNNs) comes with heavy parameter budgets, which leads to external dynamic random access memory (DRAM) for storage. The prohibitive energy of DRAM accesses makes it nontrivial for DNN deployment on resource-constrained devices, calling for minimizing the movements of weights and data in order to improve the energy efficiency. Driven by this critical bottleneck, we present SmartDeal, a hardware-friendly algorithm framework to trade higher-cost memory storage/access for lower-cost computation, in order to aggressively boost the storage and energy efficiency, for both DNN inference and training.

Lesion-Based Radiomics Signature in Pretherapy 18F-FDG PET Predicts Treatment Response to Ibrutinib in Lymphoma.

Purpose: The aim of this study was to develop a pretherapy PET/CT-based prediction model for treatment response to ibrutinib in lymphoma patients.

Patients And Methods: One hundred sixty-nine lymphoma patients with 2441 lesions were studied retrospectively. All eligible lymphomas on pretherapy 18F-FDG PET images were contoured and segmented for radiomic analysis.
