FEBS Open Bio, EarlyView.The contrast transfer function (CTF) is an imaging aberration that is a major resolution‐limiting factor in cryo‐electron microscopy (cryo‐EM). Precise CTF estimation is key to overcoming this limitation, but is particularly challenging in cryo‐electron tomography (cryo‐ET) data. Here, we present an approach for using geometric information to assist in

An ocular biomechanics environment for reinforcement learning [PDF]
arXiv, 2020 Reinforcement learning has been applied to human movement through physiologically-based biomechanical models to add insights into the neural control of these movements; it is also useful in the design of prosthetics and robotics. In this paper, we extend the use of reinforcement learning into controlling an ocular biomechanical system to perform ...

Pharmacological and physiological manipulation of ocular accommodation [PDF]
, 2017 The primary aim of this thesis was to investigate in-vivo changes to ocular morphology during ocular accommodation, with particular attention to ciliary muscle changes, using pharmacological agents and physiological stimuli. To determine the optimum target for accommodation studies, accommodative responses to different stimuli were investigated ...

Ocular Disease Classification Using CNN with Deep Convolutional Generative Adversarial Network [PDF]
Lecture Notes in Electrical Engineering, vol 1190. Springer,
Singapore. 29 September 2024The Convolutional Neural Network (CNN) has shown impressive performance in image classification because of its strong learning capabilities. However, it demands a substantial and balanced dataset for effective training. Otherwise, networks frequently exhibit over fitting and struggle to generalize to new examples.
