Effects of dietary phytol and phytanic acid in animals
Journal of Lipid Research, 1966 Feeding of phytol in large doses (2-5% by weight in the diet) led to accumulation of phytanic acid in the mouse, rat, rabbit, and chinchilla, the degree of accumulation depending upon the level of dietary intake.

On the Spectral Efficiency of Blind Channel Estimation and Synchronization Techniques [PDF]
arXiv, 2017 In the literature, channel estimation and synchronization (CE/SY) algorithms are classified as blind, and hence spectrally efficient, if they do not require pilot symbols. However, we show in this letter that such classification is not accurate and can be misleading.

Blindness, art and exclusion in museums and galleries [PDF]
, 2003 Drawing on interviews with blind people, this paper examines both their exclusion from museums and galleries and their responses to the art educational provision which is specifically designed to remedy that marginalisation.

Semi‐automated hippocampal avoidance whole‐brain radiotherapy planning
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background Hippocampal avoidance whole‐brain radiotherapy (HA‐WBRT) is designed to spare cognitive function by reducing radiation dose to the hippocampus during the treatment of brain metastases. Current manual planning methods can be time‐consuming and may vary in quality, necessitating the development of automated approaches to streamline ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background The use of deep learning‐based auto‐contouring algorithms in various treatment planning services is increasingly common. There is a notable deficit of commercially or publicly available models trained on large or diverse datasets containing high‐dose‐rate (HDR) brachytherapy treatment scans, leading to poor performance on images ...

Physiological Mechanisms Underlying Motion-Induced Blindness [PDF]
, 2008 Visual disappearance illusions - such as motion-induced blindness (MIB) - are commonly used to study the neural underpinnings of visual perception. In such illusions a salient visual target becomes perceptually invisible.

Blind Descent: A Prequel to Gradient Descent [PDF]
arXiv, 2020 We describe an alternative learning method for neural networks, which we call Blind Descent. By design, Blind Descent does not face problems like exploding or vanishing gradients. In Blind Descent, gradients are not used to guide the learning process.
