Detecting near-surface objects with seismic traveltime tomography:Experimentation at a test site [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2011 In environmental and engineering studies, detecting shallow buried objects using seismic reflection techniques iscommonly difficult when the acquisition geometry and frequency contents are limited and the heterogeneity of the subsurfaceis high.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Salt structures from inversion of residual gravity anomalies: application in Santos Basin, Brazil
Brazilian Journal of Geology, 2019 The Santos Basin, with an area of about 350.000 km 2 , is the largest salt basin of the South Atlantic, and due to its high economic hydrocarbon potential, it is a recurrent theme in scientific studies.

A New Graphical Representation of the Old Algebraic Structure
Journal of Mathematics, 2023 The most recent advancements in algebra and graph theory enable us to ask a straightforward question: what practical use does this graph connected with a mathematical system have in the real world?

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Inverse of the string theory KLT kernel
Journal of High Energy Physics, 2017 The field theory Kawai-Lewellen-Tye (KLT) kernel, which relates scattering amplitudes of gravitons and gluons, turns out to be the inverse of a matrix whose components are bi-adjoint scalar partial amplitudes.

Review of seismic inverse scattering migration and inversion
地球与行星物理论评, 2021 With the shifting toward deeper, geologically more complex, and more subtle hydrocarbon reservoirs than before, the exploration of oil and gas resources is becoming more and more difficult.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
