InfoMat, EarlyView.To address the low through‐plane thermal conductivity (λ⊥) of carbon fiber/epoxy composites, which poses thermal management challenges in the expanding low‐altitude economy, we incorporated spherical thermally reduced graphene (s‐TRG) as a bridging filler. This architectural design achieved a λ⊥ of 2.73 W m–1 K–1 at 10 wt% loading.

Tropical Cyclone Rainfall Spatial Asymmetries in the Lesser Antilles
International Journal of Climatology, EarlyView.Rainfall is not proportional to the Saffir‐Simpson wind‐based categories. Lower category tropical cyclones (TS, H1, H2 and H3) can generate more intense rainfall than H4 and H5. Rainfall is asymmetric; as a tropical cyclone intensifies or weakens, the location of peak rainfall shifts.

Failure in Motion: A Framework for Capability Erosion and Institutional Dysfunction
Strategic Change, EarlyView.ABSTRACT Drawing on the literature on capability erosion and institutional dysfunction (ID), this study develops a conceptual framework that sheds new light on how the interaction between capability erosion and ID creates conditions for business failure across borders. By articulating two dimensions of heterogeneous capability and resource erosion (i.e.

Analysis of flexible aircraft longitudinal dynamics and handling qualities. Volume 2: Data [PDF]
Two analysis methods are applied to a family of flexible aircraft in order to investigate how and when structural (especially dynamic aeroelastic) effects affect the dynamic characteristics of aircraft.

Ordered Median Traveling Salesman Problem
Networks, EarlyView.ABSTRACT This paper introduces a novel combinatorial optimization problem with ordering constraints, termed the Ordered Median Traveling Salesman Problem (OMTSP). The OMTSP integrates key elements from both the classic Traveling Salesman Problem (TSP) and the Ordered Median Location Problem.

Prediction of wing aeroelastic effects on aircraft lift and pitching moment characteristics [PDF]
The distribution of flight loads on an aircraft structure determine the lift and pitching moment characteristics of the aircraft. When the load distribution changes due to the aeroelastic response of the structure, the lift and pitching moment ...

People and Nature, EarlyView.Abstract Nature‐based tourism is a rapidly growing subsector of the international tourism industry. However, capturing broad‐scale patterns of nature visits during touristic trips or visitors' appreciation of nature may be difficult using traditional data sources and methods. In this study, we harness geotagged social media data to understand the scale
