Physics And Statistics Of Medical Imaging [PDF]
SPIE Proceedings, 1989 Extraordinary progress has been made over the last two decades in the development and dissemination of new medical imaging technologies. The development of computed tomography, positron emission tomography, and magnetic resonance imaging, as well as major innovations to the conventional imaging modalities, have revolutionized medical diagnostic imaging.

Entropy, 2010 The principle of least action provides a holistic worldview in which Nature in its entirety and every detail is described in terms of actions. Each and every action is ultimately composed of one or multiple of the most elementary actions which relates to

Single trajectory characterization via machine learning
New Journal of Physics, 2020 In order to study transport in complex environments, it is extremely important to determine the physical mechanism underlying diffusion and precisely characterize its nature and parameters.

Complexity, parallel computation and statistical physics
, 2005 The intuition that a long history is required for the emergence of complexity in natural systems is formalized using the notion of depth. The depth of a system is defined in terms of the number of parallel computational steps needed to simulate it. Depth

Detecting composite orders in layered models via machine learning
New Journal of Physics, 2020 Determining the phase diagram of systems consisting of smaller subsystems ‘connected’ via a tunable coupling is a challenging task relevant for a variety of physical settings.

Information theory and generalized statistics [PDF]
, 2003 We present a discussion of generalized statistics based on Renyi's, Fisher's and Tsallis's measures of information. The unifying conceptual framework which we employ here is provided by information theory. Important applications of generalized statistics to systems with (multi-)fractal structure are examined.

Collective dynamics of swarmalators with higher-order interactions
Communications PhysicsHigher-order interactions shape collective dynamics, but how they affect transitions between different states in swarmalator systems is yet to be determined. To that effect, we here study an analytically tractable swarmalator model that incorporates both

Thermodynamic efficiency in dissipative chemistry
Nature Communications, 2019 Open chemical systems operate out of equilibrium, providing more opportunities than closed systems, but a theoretical framework to describe their performance is lacking. Here, the authors assess the efficiency of two classes of dissipative processes with

Influence of boundary conditions on stochastic movement of biological molecular motors
Applied and Computational Mechanics, 2018 The aim of this work is to show the use of statistical physics in biomechanics, especially for modelling a muscle on molecular level. To approximate stochastic (Markovian) evolution in the spatial variable of muscle configuration, we solve the Fokker ...
