Bidirectional 10 Gb/s/λ, channel-reuse, long-reach DWDM-PON employing tunable optical transceiver with optical intensity detection-based wavelength management
We experimentally demonstrate a channel-reuse, bidirectional 10 Gb/s/λ, long-reach dense wavelength-division-multiplexing passive optical network (DWDM-PON) and an optical intensity detection-based wavelength ...

Open AccessEffectiveness of a multidimensional intervention program in improving occupational musculoskeletal disorders among intensive care unit nurses: a cluster-controlled trial with follow-up at 3 and 6 months
Intensive care unit (ICU) nurses are at high risk for work-related musculoskeletal disorders (WRMDs). Data on occupational injuries indicate the significance of WRMDs among ICU nurses. Intervention programs ha...

Open AccessUltra-fast single-crystal polymerization of large-sized covalent organic frameworks
In principle, polymerization tends to produce amorphous or poorly crystalline materials. Efficiently producing high-quality single crystals by polymerization in solvent remains as an unsolved issue in chemistr...

Rapid and ultrasensitive electromechanical detection of ions, biomolecules and SARS-CoV-2 RNA in unamplified samples
The detection of samples at ultralow concentrations (one to ten copies in 100 μl) in biofluids is hampered by the orders-of-magnitude higher amounts of ‘background’ biomolecules. Here we report a molecular sys...

New Method for the Determination of the Induction Period of Walnut Oil by Fourier Transform Infrared Spectroscopy
A new method for the determination of the induction period (IP) of walnut oil through polyethylene-film-based Fourier transform infrared (PE-FTIR) spectroscopy was developed. The IP value was used to represent...

Human papillomavirus (HPV) integration signature in cervical lesions: identification of MACROD2 gene as HPV hot spot integration site
High-risk HPV is clearly associated with cervical cancer. Integration of HPV DNA into the host genome is considered a key event in driving cervical carcinogenesis. However, the mechanism on how HR-HPV integrat...
