Demographics of individuals could largely influence their behaviors and interactions with surrounding pedestrians. This study investigates the pedestrians’ gender on microscopic walking dynamics single-file movements using trajectory data collected from a controlled experiment conducted under different density levels. Instantaneous acceleration (with time lag that varied 0.12 s to 0.68 s) versu...

BACKGROUND: Rotary nickel titanium instrument are an essential part of endodontic treatment, it is important to compare the root canal cleaning ability these instruments. AIM: This study aimed amount smear and debris layer remained following use four rotary instruments with irrigant solution: TruNatomy (TRN), Protaper Next (PTN), S-One Plus Wave One Gold (WOG). METHODS: A total 80 extracted man...

Comparative Evaluation of Cyclic Fatigue Resistance Two Single-file Rotary Instruments in Simulated Stainless Steel Curved Canals

Cryptographic file systems typically provide security by encrypting entire files or directories. This has the advantage of simplicity, but does not allow for fine-grained protection of data within very large files. This is not an issue in most general-purpose systems, but can be very important in scientific applications where some but not all of the output data is sensitive or classified. We pr...

X-NAS (eXpandable network attached storage), a highly scalable, distributed file system designed for entrylevel NAS, has been developed. It virtualizes multiple NAS systems into a single-file-system view for different kinds of clients. The core of X-NAS is a multi-protocol virtualized file system (MVFS), and its key features—a smart-code wrapper daemon, file-group mapping, and a file-handle cac...

Background and Aim: Cleaning and shaping is one of the important steps in endodontic treatment, which has an important role in root canal treatment outcome. This study evaluated the rate of file fracture and file deformation in Neolix rotary system and K-files in shaping of the mesiobuccal canal of maxillary first molars with moderate curvature.    Materials and Methods: In this ex vivo exp...
