Carbon Emissions in the Construction Industry: A Critical Review of Accounting Methods, Spatiotemporal Characteristics, Driving Factors, and Projection

The construction industry is one of the largest sources of anthropogenic CO2 emissions, and most of its carbon is embodied in upstream materials such as cement and steel. Estimates rest on three accounting frameworks, the emission-factor (EF), input-output (IO) and material-flow...

A reliability-aware framework for campaign-scale lunar construction logistics with space-elevator transshipment

Abstract Large-scale lunar construction requires campaign-level logistics models that distinguish route capacity, reliability, infrastructure commissioning, and transshipment constraints. We develop a reliability-aware three-node Earth–Apex–Moon framework comparing direct Earth–M...

Semantic Segmentation for 3D Point Clouds with Curvature-Aware Sampling and Inverse-Density Weighting

Point cloud classification and part segmentation require effective downsampling methods that reduce computational cost while preserving object boundaries, thin structures, and other informative geometric regions. However, raw point clouds are often large, irregular, and non-unifo...

A Dual-Criterion System for Surface-Localized States Identification: Application to Al(001) Surface

Angle-resolved photoemission spectroscopy (ARPES) clearly resolves surface-localized (SL) states, yet conventional density functional theory (DFT) band structures from slab calculations do not readily distinguish weakly confined SL states on surfaces such as Al(001), as tradition...
