Humeanism and Exceptions in the Fundamental Laws of Physics
Principia: An International Journal of Epistemology, 2018 It has been argued that the fundamental laws of physics do not face a ‘problem of provisos’ equivalent to that found in other scientific disciplines (Earman, Roberts and Smith 2002) and there is only the appearance of exceptions to physical laws if they

A statistical–mechanical view on source coding: physical compression and data compression [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2011 We draw a certain analogy between the classical information-theoretic problem of lossy data compression (source coding) of memoryless information sources and the statistical mechanical behavior of a certain model of a chain of connected particles (e.g., a polymer) that is subjected to a contracting force. The free energy difference pertaining to such a

Complexity and Entropy in Legal Language
Frontiers in Physics, 2021 We study the language of legal codes from different countries and legal traditions, using concepts from physics, algorithmic complexity theory and information theory. We show that vocabulary entropy, which measures the diversity of the author’s choice of

Symplectic encoders for physics-constrained variational dynamics inference
Scientific Reports, 2023 We propose a new variational autoencoder (VAE) with physical constraints capable of learning the dynamics of Multiple Degree of Freedom (MDOF) dynamic systems.

New Journal of Physics, 2017 We have theoretically and experimentally demonstrated an RF compression-based jitter-amplification effect in high-brightness electron source ultrafast electron diffraction (UED), which degrades the temporal resolution significantly.

Design considerations for gallium arsenide pulse compression photoconductive switch
Journal of Applied Physics, 2022 In this paper, we present the physics and design-space exploration of a novel pulse compression photoconductive switch (PCPS) using semi-insulating gallium arsenide (GaAs) operating in the negative differential mobility (NDM) regime of electron transport.

Atomic insights into the quasi-elastic response in shock reloading of shocked metals
Results in Physics, 2021 The quasi-elastic response has drawn much attention as an interesting phenomenon in physics of shock wave. It has been revealed that heterogeneity features such as defects on the mesoscale play important roles in the quasi-elastic response of shocked ...

The physical dimensions of the compressed breast
The British Journal of Radiology, 1991 The success of the National Breast Screening Program relies on accurate dose measurements, essential for any risk–benefit analysis and radiation protection considerations (Forrest, 1986). This need to measure absorbed doses within and around the irradiated breast necessitates the use of carefully selected materials from which phantoms and radiation ...

The Epistemology of Wrinkles: From Geology and Anatomy to Physiology [PDF]
International Journal of Biomedicine, 2016 The author studies the geometry and physics of wrinkling – drawing from geology and animal biology. The general principles behind tension and compression wrinkles are the same in geology or dermatology.
