Detection of Karst Cavities at Pile Locations Using Single-Borehole High-Density Electrical Resistivity Profiling (SHERP): Numerical and Field Validation

Applied Sciences
Karst cavities can cause substantial concrete loss, construction incidents, and inadequate bearing strata for bored piles. Advance drilling provides direct geological information but samples only a limited volume, while surface methods may lose ...

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

A cubed-sphere based method for global and regional modeling of the lithospheric magnetic field

Earth and Planetary Physics
The Earth’s magnetic field, which has been extensively observed from ground to satellite altitudes over several decades, originates from multiple sources, such as the core dynamo, the conductive mantle, the magnetized lithosphere, and the space current ...

CONCERTO: Forward modelling of interferograms for calibration

Astronomy & Astrophysics
Context . The CarbON [CII] line in post-rEionisation and ReionisaTiOn epoch (CONCERTO) instrument was a low-resolution mapping Fourier-transform spectrometer based on lumped-element kinetic inductance detector (LEKID) technology that operated at 130-310 GHz.

Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

FEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

Forward stability and model path selection

Statistics and Computing
Abstract Most scientific publications follow the familiar recipe of (i) obtain data, (ii) fit a model, and (iii) comment on the scientific relevance of the effects of particular covariates in that model. This approach, however, ignores the fact that there may exist a multitude of similarly-accurate models in which the implied effects ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

Molecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Response characteristics of ground-penetrating radar for subgrade void based on random reconstruction of soil-rock mixture

Yantu gongcheng xuebao
In order to study the response characteristics of geological radar waves to soil-rock mixed subgrade void, a microscopic model of soil-rock mixture with pores is built with considering the randomness and non-uniformity of soil-rock mixtures.
