[Fatty degeneration of upper tarsal muscle as etiological factor of acquired upper eyelid ptosis].

Purpose: To study the histological structure of the upper tarsal muscle (Müller's muscle of the upper eyelid) in patients with acquired ptosis and to confirm the presence of its fatty degeneration as an understudied etiological factor of upper eyelid ptosis.

Material And Methods: A retrospective analysis was performed covering 79 biopsy samples of Müller's muscle of the upper eyelid obtained intraoperatively. Histological examination was performed with samples prepared by waxing.

Toward Risk Reduction for Mobile Service Composition.

The advances in mobile technologies enable us to consume or even provide services through powerful mobile devices anytime and anywhere. Services running on mobile devices within limited range can be composed to coordinate together through wireless communication technologies and perform complex tasks. However, the mobility of users and devices in mobile environment imposes high risk on the execution of the tasks.

A Clustering-Based Approach to Enriching Code Foraging Environment.

Developers often spend valuable time navigating and seeking relevant code in software maintenance. Currently, there is a lack of theoretical foundations to guide tool design and evaluation to best shape the code base to developers. This paper contributes a unified code navigation theory in light of the optimal food-foraging principles.
