Lacrimal Sac Sebaceous Carcinoma [PDF]
Ophthalmic Plastic and Reconstructive Surgery, 2019 Sebaceous carcinoma is an aggressive malignancy with a high mortality rate that commonly arises in the periorbital area. Rarely, the lacrimal apparatus may be involved by either contiguous or noncontiguous spread.

Treatment outcomes after definitive radio(chemo)therapy for 17 lacrimal sac squamous cell carcinoma.
British Journal of Radiology, 2020 OBJECTIVES Tumors of the lacrimal sac are rare and life-threatening. Because of their rarity, no extensiveclinical data on their management and prognosis exist.

Comparison of Clinical Features and Treatment Outcome in Benign and Malignant Lacrimal Sac Tumors
BioMed Research International, 2020 Purpose To compare the clinical characteristics and treatment outcome between benign and malignant lacrimal sac tumors. Methods We retrospectively reviewed the medical records of all patients with pathologically confirmed lacrimal sac lesions from 1995 ...

Target Entropy Annealing for Discrete Soft Actor-Critic [PDF]
neurips 2021 deep rl workshop, 2021 Soft Actor-Critic (SAC) is considered the state-of-the-art algorithm in continuous action space settings. It uses the maximum entropy framework for efficiency and stability, and applies a heuristic temperature Lagrange term to tune the temperature $\alpha$, which determines how "soft" the policy should be.

Lacrimal sac compression by an anterior ethmoidal mucocele: A rare case report
The Pan-American Journal of Ophthalmology, 2023 The lacrimal sac compression by an anterior ethmoidal mucocele is unusual. The ethmoidal mucocele may masquerade as lacrimal sac mucocele and may lead to disastrous consequences if treated along the lines of lacrimal mucocele.

Lacrimal duct obstruction after radioiodine therapy: case report and treatment [PDF]
, 2014 Iodotherapy represents the radioactive iodine therapy. The beta radiation emitted by radioactive iodine are particles that will be stored in the thyroid tissue destroying cancer cells that were left after surgery (thyroidectomy).

On a generalized Auslander-Reiten conjecture [PDF]
arXiv, 2022 It is well-known that the generalized Auslander-Reiten condition (GARC) and the symmetric Auslander condition (SAC) are equivalent, and (GARC) implies that the Auslander-Reiten condition (ARC). In this paper we explore (SAC) along with the several canonical change of rings $R \to S$. First, we prove the equivalence of (SAC) for $R$ and $R/xR$, where $x$

Chronic Lymphocytic Leukaemia/ Small-Cell Lymphocytic Lymphoma of the Lacrimal Sac: A Case Series. [PDF]
, 2017 BackgroundLymphomas of the lacrimal sac are rare, accounting for less than 10% of lacrimal sac malignant tumours. They may present with symptoms typical of secondary acquired nasolacrimal duct obstruction and are thus often misdiagnosed.MethodsCase ...

Endoscopic Dacryocystorhinostomy: Creation of a Large Marsupialized Lacrimal Sac [PDF]
, 2006 This retrospective study describes and evaluates the effectiveness of a modified technique of conventional endoscopic dacryocystorhinostomy (DCR) that minimizes the obstruction of a neo-ostium by creating an enlarged marsupialized lacrimal sac using ...

Improved Soft Actor-Critic: Mixing Prioritized Off-Policy Samples with On-Policy Experience [PDF]
arXiv, 2021 Soft Actor-Critic (SAC) is an off-policy actor-critic reinforcement learning algorithm, essentially based on entropy regularization. SAC trains a policy by maximizing the trade-off between expected return and entropy (randomness in the policy). It has achieved state-of-the-art performance on a range of continuous-control benchmark tasks, outperforming ...
