[Purpose] The purpose of this study was to ergonomically evaluate the work posture of dentists to examine their subsequent risk of developing musculoskeletal diseases. [Subjects and Methods] Scenes in which the three dentists performed procedures at their dental clinics were videotaped. The videotapes of the dentists' work postures were evaluated and analyzed by using the Rapid Upper Limb Asses...

Realizing the full potential of quantum computation requires error correction (QEC), with most recent breakthrough demonstrations QEC using surface code. codes use multiple noisy physical qubits to encode information in fewer logical qubits, enabling identification errors through a decoding process. This process increases fidelity (or accuracy) making more reliable. However, fast (efficient run...

 Background: The aim of this paper was the comparison of ergonomic risk assessment results (final score and action levels) for the entire body as determined using Quick Exposure Check (QEC) and Rapid Entire Body Assessment (REBA).  Materials and Methods: This was a cross-sectional study in which all 82 workers engaged in various processes with different activities in an anodizing a...

Quantum computation faces considerable hurdles, one of the most serious being engineering physical systems performing coherent operations without the deleterious effects of decoherence,1 particularly in the solid state. However by isolation and manipulation of states of quantum dot QD structures,2 it may be possible to perform many unitary operations within the dephasing time, a pre-requisite f...

BACKGROUND Work-related musculoskeletal disorders (WMSDs) are a common health problem throughout the world and a major cause of disability in the workplace. OBJECTIVE To determine the prevalence rate of MSDs, assessment of ergonomics working conditions and identification of major risk factors associated with MSDs symptoms among employees of Iranian petrochemical industries between October 200...

background: during the last decades, to assess the risk factors of work-related musculoskeletal disorders (wmsds), enormous observational methods have been developed. rapid entire body assessment (reba) and quick exposure check (qec) are two general methods in this field. this study aimed to compare ergonomic risk assessment outputs from qec and reba in terms of agreement in distribution of pos...

We reapply our approach to designing nanophotonic quantum memories to formulate an optical network that autonomously protects a single logical qubit against arbitrary single-qubit errors. Emulating the 9 qubit Bacon-Shor subsystem code, the network replaces the traditionally discrete syndrome measurement and correction steps by continuous, time-independent optical interactions and coherent feed...
