Dual picosecond fast tunable optical parametric amplifier laser system for wide-field nonlinear optical microscopy

APL Photonics
In the last decades, nonlinear optical microscopy techniques, such as two-Photon Excited Fluorescence (2PEF), Sum Frequency Generation (SFG), and Hyperspectral Coherent Anti-Stokes Raman Scattering (H-CARS) microscopy, emerged as powerful tools to image ...

Study of a Welding Pool Harmonic Oscillations Influence on the Welded Metal Hardness and Weld Bead Width

Журнал інженерних наук, 2019
The comparison results of the hardness measuring of welded metal and the heat-affected zone of the eight welded beads from low-carbon steel obtained by surfacing CO2/MAG with welding bath oscillation influence at values of amplitude equaled 0.5 mm ...

ADP‐ribosylation: An emerging regulator of the epigenome

Molecular Oncology, EarlyView.
ADP‐ribosylation has emerged as a dynamic epigenetic signaling mechanism that modifies histones and chromatin‐associated proteins. Through coordinated PARylation and MARylation, it integrates with other histone modifications to regulate chromatin structure, transcription factor activity, and gene expression, influencing genome function and disease ...

Physical Simulation of Ultrasonic Imaging Logging Response

Sensors, 2022
Ultrasonic imaging logging can visually identify the location, shape, dip angle and orientation of fractures and holes. The method has not been effectively applied in the field; one of the prime reasons is that the results of physical simulation ...

Identifying and characterising a plant GH1 β‐glucosidase that exhibits hydrolytic activity on N‐linked glucopyranoside

FEBS Open Bio, EarlyView.
We report the first β‐glucosidase with demonstrated hydrolytic activity on an N‐linked glycopyranoside. The enzyme, native to maize, was biochemically characterised for this novel reaction, and structural modelling of the enzyme–substrate complex revealed several clues to the underlying reduced catalytic rate relative to its native O‐glycopyranoside ...

Amplitude death induced by a global dynamic coupling

, 2007
This paper presents a dynamic connection that can induce amplitude death in globally coupled oscillators. A linear analysis clarifies a local stability condition for global amplitude death.

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Investigating the Impact of Undulation Amplitude of Unconventional Oil Well Laterals on Transient Multiphase Flow Behavior: Experimental and Numerical Study

Fuels, 2023
The growing popularity of unconventional wells has led to increased interest in assessing and predicting their production performance. These wells, with their extended-reach structures, are able to generate and access larger reservoir volumes. Therefore,
