Pre-late Devensian high-arctic marine deposits in SW Scotland [PDF]

open access: yes, 2010
We present new interpretations of Digital Elevation Model (DEM) data and marine fossils collected from three sites on the Rhins of Galloway which, contrary to recent proposals, suggest that the landforms and deposits of the region do not represent ...

Circulating tumor DNA (ctDNA) trajectories predict survival in trifluridine/tipiracil‐treated metastatic colorectal cancer patients

open access: yesMolecular Oncology, EarlyView.
The authors applied joint/mixed models that predict mortality of trifluridine/tipiracil‐treated metastatic colorectal cancer patients based on circulating tumor DNA (ctDNA) trajectories. Patients at high risk of death could be spared aggressive therapy with the prospect of a higher quality of life in their remaining lifetime, whereas patients with a ...

Digital elevation model correction in urban areas using extreme gradient boosting, land cover and terrain parameters [PDF]

open access: yesarXiv, 2023
The accuracy of digital elevation models (DEMs) in urban areas is influenced by numerous factors including land cover and terrain irregularities. Moreover, building artifacts in global DEMs cause artificial blocking of surface flow pathways. This compromises their quality and adequacy for hydrological and environmental modelling in urban landscapes ...

Non-affine georectification to improve the topographic fidelity of legacy geologic maps

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2022
Field-based geologic maps, which are among the most valuable tools of communication among geoscientists, can be expensive and time-consuming to produce or manually revise.

Multiple GPS Measurements for Digital Elevation Model [PDF]

open access: yes, 2006
Accurate representation of field topography is required for implementation of precision conservation management practices. Topographic data for the development of agricultural field digital elevation models (DEM) can be acquired using GPS-equipped farm ...

Integrative analysis of circulating tumor cells (CTCs) and exosomes from small‐cell lung cancer (SCLC) patients: a comprehensive approach

open access: yesMolecular Oncology, EarlyView.
This study simultaneously investigated circulating tumor cells (CTCs) and exosomes from small‐cell lung cancer (SCLC) patients. The elevated expression of JUNB and CXCR4 in CTCs was a poor prognostic factor for SCLC patients, whereas exosomal overexpression of these biomarkers revealed a high discrimination ability of patients from healthy individuals,

Geomorphometric modeling and mapping of Antarctic oases [PDF]

open access: yesarXiv, 2023
Geomorphometric modeling is widely used in geosciences. However, geomorphometric modeling and mapping of Antarctic oases has not been performed so far. This article presents the first results of our work on geomorphometric modeling and mapping of several Antarctic oases including the Larsemann Hills, Thala Hills, Schirmacher oasis, and Fildes Peninsula.

A Comparative Study of Three Non-Geostatistical Methods for Optimising Digital Elevation Model Interpolation

open access: yesISPRS Int. J. Geo Inf., 2018
It is common to generate digital elevation models (DEMs) from aerial laser scanning (ALS) data. However, cost and lack of knowledge may preclude its use. In contrast, global navigation satellite systems (GNSS) are seldom used to collect and generate DEMs.

Obesity alters the fitness of peritumoral adipose tissue, exacerbating tumor invasiveness in renal cancer through the induction of ADAM12 and CYP1B1

open access: yesMolecular Oncology, EarlyView.
Tumor microenvironment drives cancer formation and progression. We analyzed the role of human cancer‐associated adipocytes from patients with renal cell carcinoma (RCC) stratified as lean, overweight, or obese. RNA‐seq demonstrated that, among the most altered genes involved in the tumor–stroma crosstalk, are ADAM12 and CYP1B1, which were proven to be ...
