Hemangiopericytoma of the Lacrimal Sac
Ophthalmology, 1991 Hemangiopericytomas of the orbit are rare tumors with low malignancy potential. To the authors' knowledge, only three previous cases of these tumors occurring in the lacrimal sac have been reported. The authors report a fourth case. Follow-up was obtained on the first reported case, and the patient in that case had a recurrence after 15 years.

SHA-1 and the Strict Avalanche Criterion [PDF]
arXiv, 2016 The Strict Avalanche Criterion (SAC) is a measure of both confusion and diffusion, which are key properties of a cryptographic hash function. This work provides a working definition of the SAC, describes an experimental methodology that can be used to statistically evaluate whether a cryptographic hash meets the SAC, and uses this to investigate the ...

Band-limited Soft Actor Critic Model [PDF]
arXiv, 2020 Soft Actor Critic (SAC) algorithms show remarkable performance in complex simulated environments. A key element of SAC networks is entropy regularization, which prevents the SAC actor from optimizing against fine grained features, oftentimes transient, of the state-action value function.
