A BIM-based Framework for Building Depreciation Estimation through Maintenance Management Integration [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
This paper proposes a framework for dynamic depreciation estimation by integrating Building Information Modelling (BIM), cost estimation datasets and maintenance data from Computerized Maintenance Management Systems (CMMS) or Facility Management Systems (

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Finding the Optimal Convolutional Kernel Size for Semantic Segmentation of Pole-like Objects in Lidar Point Clouds [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Pole-like objects (PLOs) are important street assets in urban environments, yet current deep learning methods often underperform in their segmentation compared to other objects.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Zero-Shot 3D Asset Detection and Localisation Through Visual Grounding in Industrial Point Clouds

AI
3D scene understanding in industrial environments is crucial for effective operation and maintenance (O&M) and asset monitoring. However, accurate asset detection and localisation face significant challenges due to asset diversity and scene complexity in

Pole-NN: Few-Shot Classification of Pole-Like Objects in Lidar Point Clouds [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
In the realm of autonomous systems and smart-city initiatives, accurately detecting and localizing pole-like objects (PLOs) such as electrical poles and traffic signs has become crucial.

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

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 ...

3D Cadastral Database Systems—A Systematic Literature Review

ISPRS International Journal of Geo-Information
Cadastral databases have been used for over 20 years, but most contain 2D data. The increasing presence of high-rise buildings with modern architecture complicates the process of determining property rights, restrictions, and responsibilities.
