TS-MUWSN: Time synchronization for mobile underwater sensor networks [PDF]

, 2016
Time synchronization is an important, yet challenging, problem in underwater sensor networks (UWSNs). This challenge can be attributed to: 1) messaging timestamping; 2) node mobility; and 3) Doppler scale effect. To mitigate these problems, we present an

H2‐Driven Flavin Recycling Supports Biocatalytic Halogenation by Flavin‐Dependent Halogenase

ChemCatChem, Volume 18, Issue 2, 28 January 2026.
Use of a H2‐driven flavin recycling system based on the O2‐tolerant [NiFe] hydrogenase 1 from E. coli supports efficient halogenation catalyzed by the flavin‐dependent halogenase, PyrH. Operation under atmospheric H2 with controlled delivery of safe, low‐level O2 enables intensification of biocatalytic halogenation.

Defect recognition of circumferential welds of pipelines in TOFD images based on YOLOv5

Hanjie xuebao
In order to enhance defect recognition in time-of-flight diffraction (TOFD) scan images for circumferential welds of pipelines under conditions such as background signal interference and uneven sample distribution, an improved YOLOv5s network model was ...

Sensitivity of near‐surface marine winds and wind stress in coastal Antarctica to regional atmospheric model configuration

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 772, October 2025 Part A.
Marine winds near coastal Antarctica are important for sea‐ice variability and ocean circulation. We test the sensitivity of simulated winds to varying uncertain aspects of the atmospheric model configuration. Winds (each configuration a coloured solid line in the figure) are sensitive to model physics, and notably we find that wind stress over a ...

Structural and Kinetics Studies of N^O‐, O^N^O‐, and N^N‐ Schiff Base Mn Complexes as Highly Active Catalysts in the Ring‐Opening Polymerization of rac‐Lactides

European Journal of Inorganic Chemistry, Volume 28, Issue 19, July 12, 2025.
Mononuclear and multinuclear manganese of (imino)phenol/pyridine proligands have been structurally characterized. The complexes form active catalysts in the ring‐opening polymerization of rac‐lactides to give predominantly atactic (poly)lactides with moderate molecular weights and good control of the polymer microstructure.

Development of phased array probes to operate in time-of-flight diffraction configuration to continuously monitor defect growth in thermal power plants [PDF]

, 2015
A high temperature (HT) structural health monitoring system for pipes that utilises phased array (PA) probes in time-of-flight diffraction (TOFD) configuration to continuously monitor the defect growth over time is being developed, so that when the ...

Analysis of the wind response to resolved versus parametrized turbulent orographic drag in high‐resolution simulations

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 770, July 2025 Part A.
This study analyzes the impact of orographic drag on the lower atmosphere over moderately complex terrain using high‐resolution ICON simulations. Numerical simulations explore the effects of parametrizations over moderately complex terrain near the Perdigao experiment site and the Serra da Estrela mountain range by comparing km‐ and 100‐m‐scale ...
