International Journal of Radiation Oncology, Biology, Physics, 2022 INTRODUCTION The delineation of target volumes and organs at risk is the main source of uncertainty in radiation therapy (RT)(1). Numerous inter-observer variability (IOV) studies have been conducted, often with unclear methodology and non-standardized ...

PINN-Obs: Physics-Informed Neural Network-Based Observer for Nonlinear Dynamical Systems [PDF]
Engineering applications of artificial intelligenceState estimation for nonlinear dynamical systems is a critical challenge in control and engineering applications, particularly when only partial and noisy measurements are available.

Inside the hologram: reconstructing the bulk observer’s experience [PDF]
Journal of High Energy Physics, 2020 We develop a holographic framework for describing the experience of bulk observers in AdS/CFT, that allows us to compute the proper time and energy distribution measured along any bulk worldline.

The intersection between quantum physics and trauma in Yusef Komunyakaa’s “You and I Are Disappearing” [PDF]
Journal of Languages and TranslationThis paper discusses the intersection of quantum physics and war trauma in Yusef Komunyakaa’s (1988) “You and I Are Disappearing,” investigating the experience of war trauma through the fragmented temporal perspective as presented in quantum mechanics ...

Interpretation in quantum physics as hidden curriculum [PDF]
, 2010 Prior research has demonstrated how the realist perspectives of classical physics students can translate into specific beliefs about quantum phenomena when taking an introductory modern physics course.

Student perspectives in quantum physics [PDF]
, 2008 Introductory courses in classical physics are promoting in students a realist perspective, made up in part by the belief that all physical properties of a system can be simultaneously specified, and thus determined at all future times. Such a perspective

Interpreting Observations of Physical Systems [PDF]
IEEE Transactions on Systems, Man, and Cybernetics, 1987 An unsolved problem in creating diagnostic expert systems is generating a qualitative understanding of how the system is behaving from raw data, especially numerical data taken across time. Yet automating this critical step is necessary for building the next generation of expert systems.

Absolute entropy and the observer’s no-boundary state [PDF]
Journal of High Energy PhysicsWe investigate the no-boundary proposal for closed universes with an observer. We argue that the observer’s no-boundary state is the identity operator on the physical Hilbert space, i.e., the maximum entropy state and show this explicitly in Jackiw ...
