Perovskite single-crystal thin films: preparation, surface engineering, and application
Nano Convergence, 2023 Perovskite single-crystal thin films (SCTFs) have emerged as a significant research hotspot in the field of optoelectronic devices owing to their low defect state density, long carrier diffusion length, and high environmental stability.

Global increase and geographic convergence in antibiotic consumption between 2000 and 2015
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Antibiotic resistance, driven by antibiotic consumption, is a growing global health threat. Our report on antibiotic use in 76 countries over 16 years provides an up-to-date comprehensive assessment of global trends in antibiotic consumption.

Relationship between hepatocellular carcinoma circulating tumor cells and tumor volume
Cancer Convergence, 2018 Background Microfluidic platforms have demonstrated the ability to isolate rare circulating tumor cells from a wide variety of cancers. Our group has recently shown the ability to isolate circulating tumor cells (CTCs) from hepatocellular carcinoma (HCC)

Achieving Geometric Convergence for Distributed Optimization Over Time-Varying Graphs [PDF]
SIAM Journal on Optimization, 2016 This paper considers the problem of distributed optimization over time-varying graphs. For the case of undirected graphs, we introduce a distributed algorithm, referred to as DIGing, based on a combination of a distributed inexact gradient method and a ...

Data‐driven performance metrics for neural network learning
International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary Effectiveness of data‐driven neural learning in terms of both local mimima trapping and convergence rate is addressed. Such issues are investigated in a case study involving the training of one‐hidden‐layer feedforward neural networks with the extended Kalman filter, which reduces the search for the optimal network parameters to a state ...

Synergistic convergence and substituted convergence
Indian Journal of Ophthalmology, 2013 Dear Editor, Jain et al.[1] described two intriguing cases with horizontal gaze palsy and progressive scoliosis. In the article, bilateral adduction on attempted lateral gaze was referred to by the term ‘synergistic convergence’. Bilateral deficit of abduction associated with simultaneous bilateral adduction on attempted lateral gaze has been ...

Super-convergence: very fast training of neural networks using large learning rates
Defense + Commercial Sensing, 2018 In this paper, we describe a phenomenon, which we named “super-convergence”, where neural networks can be trained an order of magnitude faster than with standard training methods.

Spectroscopic single-molecule localization microscopy: applications and prospective
Nano Convergence, 2023 Single-molecule localization microscopy (SMLM) breaks the optical diffraction limit by numerically localizing sparse fluorescence emitters to achieve super-resolution imaging. Spectroscopic SMLM or sSMLM further allows simultaneous spectroscopy and super-
