Accuracy research on coded levelling staff using digital photos

open access: yesGeodesy and Cartography, 2012
The article introduces accuracy research on coded levelling staff using digital photos. The principles of photogrammetry can be used for comparing the views of the etalon and meter to be calibrated.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Sticky Pixels: Evolutionary Growth by Random Drop Ballistic Aggregation [PDF]

open access: yes, 2001
Over the years many techniques have been developed for simulating and modelling trees, ferns, crystals and natural structures. Indeed, many complex and realistic images have been formed.

The application of photogrammetric numerical methods to the analysis of magnetic resonance images

open access: yesGeodesy and Cartography, 2012
Research on the identification possibilities and accuracy of digital images applying the theory of covariations functions is presented. The digital magnetic resonance images are processed by Matlab 7 computer program. The digital magnetic resonance image

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Adding Lines Along Pixels: Remote Sensing, Traditional Knowledge and Human–Fire Interactions in Ethiopia and India

open access: yesGeo: Geography and Environment
This study critically examines the limitations of satellite remote sensing (SRS) in capturing the complexities of human–fire interactions. It proposes a relational approach grounded in the embodied, place‐based knowledge of communities living with fire ...

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

Reducing metal artifacts by restricting negative pixels

open access: yesVisual Computing for Industry, Biomedicine, and Art, 2021
When the object contains metals, its x-ray computed tomography (CT) images are normally affected by streaking artifacts. These artifacts are mainly caused by the x-ray beam hardening effects, which deviate the measurements from their true values.

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

open access: yesMolecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic
