Topographic and Climatic Determinants of Soil Organic Carbon Across Landscapes: A Meta‐Analysis
Land Degradation &Development, EarlyView.ABSTRACT The soil is the greatest natural store of organic carbon, holding between 1500 to 1550 Pg C of organic carbon at the top 100 cm of the soil globally—roughly twice the carbon pool in the atmosphere. The spatial distribution of this stock is controlled by a complex chain of controls: topographic position regulates the hydrological redistribution,

Intensity Noise Dynamics in Terahertz Quantum Cascade Lasers
Laser &Photonics Reviews, EarlyView.Intensity‐noise dynamics in terahertz quantum cascade lasers are investigated across single‐mode, dense‐comb and harmonic‐comb regimes using graphene thermoelectric detectors. Harmonic combs show ∼10% lower relative intensity noise, while RIN scales as P0−γ$P_0^{ - \gamma }$ with γ≈1.2$\gamma \approx 1.2$, revealing a crossover from spontaneous ...

From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications
Laser &Photonics Reviews, EarlyView.Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

Property Rights Entrepreneurship: The Drive for Product, Asset, and Resource Excludability
Managerial and Decision Economics, EarlyView.ABSTRACT Property rights are foundational to market economies, and entrepreneurial activity depends heavily on the excludability afforded by property rights. Yet, the role of entrepreneurs in shaping the evolution of property rights has been so thoroughly taken for granted that it often vanishes from analyses.

Exact Methods for the Cumulative Capacitated Vehicle Routing Problem With Time Windows
Networks, EarlyView.ABSTRACT This article studies the cumulative capacitated vehicle routing problem with time windows (CCVRPTW). The CCVRPTW consists of deciding the routing schedules for a set of homogeneous capacitated vehicles such that the latency, that is, the sum of the service start times at the customers, is minimized and the time windows as well as the vehicle ...

People and Nature, EarlyView.Abstract Forests play a pivotal role in sustainability transitions. This article explores how people's relationships with forests, particularly how they care for or take care of them, shape and reflect broader tendencies and tensions in forest utilization and governance.

Iron(III) ion reinforced P(NiPAAm‐co‐AA) beads as tunable smart organogels
Polymer International, EarlyView.Macroporous beads of PNiPAAm‐co‐AA copolymers were further crosslinked by iron(III) ions. The resulting beads are mechanically robust and reversibly responsive to a change of solvent from ethanol to ethyl acetate with half‐lives in the range of minutes.
