Terminal Transient Phase of Chaotic Transients
Physical 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.

Journal 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

Differentiable transient rendering [PDF]
ACM 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

Indian Journal of Pathology and Microbiology, 2009 A new born with a mongoloid slant, brachycephaly and low-set ears presented at birth with a total leucocyte count of 57 x 10(3)/microL and the differential leucocyte count revealed 70% of these to be blasts. The morphology of the blasts was not characteristic of myeloid and lymphoid lineage.
