BACKGROUND Most of the available instruments aimed to assess risk exposure associated with work-related musculoskeletal disorders were originally developed in English, which makes their use difficult in countries such as Brazil. OBJECTIVE To test the clinimetric properties of the Quick Exposure Check (QEC) instrument previously adapted into Brazilian-Portuguese. METHOD The original version ...

Large-scale universal quantum computing requires the implementation of quantum error correction (QEC). While the implementation of QEC has already been demonstrated for quantum memories, reliable quantum computing requires also the application of nontrivial logical gate operations to the encoded qubits. Here, we present examples of such operations by implementing, in addition to the identity op...

the musculoskeletal disorders cover a large percent of occupational diseases; therefore, in order to protect workers from such disorders, there is a need to evaluate workers positions at work in different industries. in a major furniture manufacture located in tehran, 500 workers were examined. these workers were divided into fourteen working groups, including production lines of water-heater, ...

This paper describes the development and evaluation of the Quick Exposure Check (QEC), which is an observational tool developed for Occupational Safety and Health (OSH) practitioners to assess exposure to risks for work-related musculoskeletal disorders and provide a basis for ergonomic interventions. The tool is based on epidemiological evidence and investigations of OSH practitioners' aptitud...

Dalam kegiatan produksi tidak terlepas dari operator, dalam interaksi antara manusia dan mesin tersebut membutuhkan postur tubuh yang baik agar produk dikeluarkan lebih optimal. Sering kali para pekerja mengalami nyeri otot saat melakukan pekerjaan terutama pada bagian leher punggung, hal dikarenakan oleh kerja ergonomi sehingga berakibat tingginya terjadi risiko cedera musculoskeletal disorder...

Leakage outside of the qubit computational subspace poses a threatening challenge to quantum error correction (QEC). We propose scheme using two leakage-reduction units (LRUs) that mitigate these issues for transmon-based surface code, without requiring an overhead in terms hardware or QEC-cycle time as previous proposals. For data qubits we consider microwave drive transfer leakage readout res...

It is important to protect quantum information against decoherence and operational errors, and quantum error-correcting (QEC) codes are the keys to solving this problem. Of course, just the existence of codes is not efficient. It is necessary to perform operations fault-tolerantly on encoded states because error-correction process (i.e., encoding, decoding, syndrome measurement and recovery) it...

Measurement-based (or one-way) quantum error correction (MBQEC) is a method with the capability to detect and correct any errors present in a measurement-based quantum computation (MBQC) setup [1]. There are a variety of methods and protocols we can use to perform QEC, although few that have been successfully implemented experimentally [2, 3]. An MBQC protocol requires a resource state and will...
