The Spatial Solow Model [PDF]

In this paper, we solve a Solow model in continuous time and space. We prove the existence of a solution to the problem and its convergence to a stationary solution.

Modern and Ancient Genomes Reveal Neolithic Paternal Expansions of Millet and Rice Farmers and Demic Diffusion from China into Mainland Southeast Asia

Advanced Science, EarlyView.
This study clarifies the genetic patterns of paternal lineages across East Asia and Mainland Southeast Asia. Han populations are relatively homogeneous, whereas southern ethnolinguistic minorities display regional structures. Shared Y‐chromosome lineages indicate Neolithic expansions and extensive north‐south gene flow, supporting demic diffusion ...

Geographic Space as Manifolds

The communications and interrelations between different locations on the Earth's surface have far-reaching implications for both social and natural systems. Effective spatial analytics ideally require a spatial representation, where geographic principles are succinctly expressed within a defined metric space.

Natural Negative Feedback Loops Confer Indica‐Japonica Differentiation for Grain Size Homeostasis in Rice

Advanced Science, EarlyView.
This study reveals the genetic and molecular mechanisms controlling grain size homeostasis through fine‐tuning OsGRX8 self‐expression by two natural negative feedback loops functioning in redox‐dependent or ‐independent manners and identifies two self‐regulatory haplotypes (SRHs) for the subspecies differentiation in rice.

Alphaviral Capsid Proteins Inhibit Stress Granule Assembly via Competitive RNA Binding With G3BP1

Advanced Science, EarlyView.
Stress granules exert antiviral functions. This study illustrates a conserved function of alphaviral capsid proteins in modulating stress granules. Oligomerization mediated by a helical motif coupled with a positively charged intrinsically disordered region (IDR) directly competes with G3BP1 for RNA binding, thereby disrupting G3BP1‐RNA liquid–liquid ...

Compartmentalized Homeostasis Drives High Bamboo Forest Productivity under Nutrient Imbalance

Advanced Science, EarlyView.
This study reveals how Moso bamboo achieves high productivity despite nutrient‐poor soils. It employs a unique strategy, maintaining strict nutrient balance in its leaves while using woody tissues as flexible storage reservoirs. This compartmentalized mechanism buffers the plant from soil phosphorus limitation and microbial competition, resolving the ...

Exploring the topographical pattern beneath the water surface: Global bathymetric volume-area-height curves (BVAH) of inland surface water bodies

Geodesy and Geodynamics
Global inland surface water bodies such as lakes and reservoirs, important components of the hydrosphere and ecosphere, are increasingly affected by climate change.

Comparisons of Spatially Downscaling TMPA and IMERG over the Tibetan Plateau

Remote Sensing, 2018
Accurate precipitation data is crucial in many applications such as hydrology, meteorology, and ecology. Compared with ground observations, satellite-based precipitation estimates can provide much more spatial information to characterize precipitation ...
