Leaf anatomy of the South African Danthonieae (Poaceae). XVIII. Centropodia mossamedensis

Bothalia: African Biodiversity & Conservation, 1989
The leaf blade anatomy of Centropodia mossamedensis (Rendle) T. A. Cope [=  Asthenatherum mossamedense (Rendle) Conert] is described and illustrated. This description is based on freshly fixed material and confirms that this species has Kranz anatomy ...

What Do Large Language Models Know About Materials?

Advanced Engineering Materials, EarlyView.
If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...

Comparative wood and leaf anatomy of the Cecropiaceœ (Urticales)

Bulletin du Muséum National d'Histoire Naturelle Section B,Adansonia, botanique, phytochimie, 1983
The wood and leaf anatomy of the 6 genera of the Cecropiaceæ are described in detail. The anatomical data are compared with those of the allied Moraceæ and Urticaceæ. The relationship between habit, habitat, and anatomical characters is discussed, as well as the relationships within the family.

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

Advanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Seasonal Changes in Specific Leaf Weight and Leaf Anatomy of Apple

HortScience, 1987
Abstract Newly expanded interior canopy leaves of apple ( Malus domestica Borkh.) had lower specific leaf weight (SLW), leaf thickness, palisade depth, and number of palisade cell layers than middle or peripheral leaves from late May to early October. Leaves on the periphery

The influence of leaf anatomy on the internal light environment and photosynthetic electron transport rate: exploration with a new leaf ray tracing model

Journal of Experimental Botany, 2016
Highlight A new model of the dicot leaf shows that different chloroplasts can experience drastically different light conditions and that bundle sheath extensions and chloroplast positioning influence photosynthetic light use efficiency.
