Gintropy: Gini Index Based Generalization of Entropy
Entropy, 2020 Entropy is being used in physics, mathematics, informatics and in related areas to describe equilibration, dissipation, maximal probability states and optimal compression of information.

Physics of compressed baryonic matter [PDF]
Journal of Physics: Conference Series, 2013 The experimental investigation of the QCD phase diagram with heavy ion collisions is an ongoing intense research topic at international accelerator facilities since the 80's and recently got new boost with the first results from the LHC experiments. Together with results from the top RHIC energies they investigate partonic matter in every detail at ...

Energy Equality in Compressible Fluids with Physical Boundaries [PDF]
SIAM Journal on Mathematical Analysis, 2020 We study the energy balance for weak solutions of the three-dimensional compressible Navier--Stokes equations in a bounded domain. We establish an $L^p$-$L^q$ regularity conditions on the velocity field for the energy equality to hold, provided that the density is bounded and satisfies $\sqrt \in L^\infty_t H^1_x$.

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

Exploring the Consequences of Crowd Compression Through Physics-Based Simulation
Sensors, 2018 Statistical analysis of accidents in recent years shows that crowd crushes have become significant non-combat, non-environmental public disasters. Unlike common accidents such as fires, crowd crushes may occur without obvious external causes, and may ...

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

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.

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

Sar Super-Resolution Using Physics-Aware Adaptive Compressed Sensing
IGARSS 2022 - 2022 IEEE International Geoscience and Remote Sensing Symposium, 2022 The resolution requirements of modern radar applications are increasing rapidly and cannot be fulfilled by the limited number of wide-band radar systems. Many approaches have been explored to solve this problem under the topic of superresolution. In this paper, we propose a hybrid algorithm for resolution improvement, where we aim to combine the ...
