Terminal Transient Phase of Chaotic Transients

open access: yesPhysical Review Letters, 2018
Transient chaos in spatially extended systems can be characterized by the length of the transient phase, which typically grows quickly with the system size (supertransients). For a large class of these systems, the chaotic phase terminates abruptly, without any obvious precursors in commonly used observables.

Transient Osteoporosis

open access: yesJournal of the American Academy of Orthopaedic Surgeons, 2008
Transient osteoporosis is characterized primarily by bone marrow edema. The disease most commonly affects the hip, knee, and ankle in middle-aged men. Its cause remains unknown. The hallmark that separates transient osteoporosis from other conditions presenting with a bone marrow edema pattern is its self-limited nature. Laboratory tests usually do not

Experimental study on propagation characteristics of rotating detonation wave with kerosene fuel-rich gas

open access: yesDefence Technology, 2022
In this study, kerosene fuel-rich gas produced by the combustion in the gas generator was used as the fuel and oxygen-rich air was used as the oxidant to investigate the propagation characteristics of the rotating detonation wave (RDW). The initiation of

Differentiable transient rendering [PDF]

open access: yesACM Transactions on Graphics, 2021
Recent differentiable rendering techniques have become key tools to tackle many inverse problems in graphics and vision. Existing models, however, assume steady-state light transport, i.e., infinite speed of light. While this is a safe assumption for many applications, recent advances in ultrafast imaging leverage the wealth of information
