Stateless and Delivery Guaranteed Geometric Routing on Virtual Coordinate System [PDF]

arXiv, 2008
Stateless geographic routing provides relatively good performance at a fixed overhead, which is typically much lower than conventional routing protocols such as AODV. However, the performance of geographic routing is impacted by physical voids, and localization errors.

Genomic Insights into Post‐Domestication Expansion and Selection of Body Size in Ponies

Advanced Science, EarlyView.
The authors’ research delves into the history of ponies by assembling a pony genome and integrating horse genomes. This unveils genetic connections between Asian and European pony breeds. Cis‐regulatory elements of key genes impacting body size are also identified.

Estimating Savanna Clumping Index Using Hemispherical Photographs Integrated with High Resolution Remote Sensing Images

Remote Sensing, 2017
In contrast to herbaceous canopies and forests, savannas are grassland ecosystems with sparsely distributed individual trees, so the canopy is spatially heterogeneous and open, whereas the woody cover in savannas, e.g., tree cover, adversely affects ...

The Semi‐Natural Climate Chambers across Latitudes: A Broadly Applicable Husbandry and Experimental System for Terrestrial Ectotherms under Climate Change

Advanced Science, EarlyView.
Assessing species' vulnerabilities across geographical gradients is essential for biodiversity conservation under climate change. To address this challenge, the semi‐natural climate chamber across latitudes (SCCAL) is developed, a validated system capable of simulating thermal environments for ecological experiments without reliance on water or ...

GeoRAG: A Question-Answering Approach from a Geographical Perspective [PDF]

arXiv
Geographic Question Answering (GeoQA) addresses natural language queries in geographic domains to fulfill complex user demands and improve information retrieval efficiency. Traditional QA systems, however, suffer from limited comprehension, low retrieval accuracy, weak interactivity, and inadequate handling of complex tasks, hindering precise ...
