A novel red‐edge spectral index for retrieving the leaf chlorophyll content
Methods in Ecology and Evolution, Volume 13, Issue 12, Page 2771-2787, December 2022., 2022 Abstract The leaf chlorophyll content (Chlleaf) is a crucial vegetation parameter in carbon cycle modelling and agricultural monitoring at local, regional and global scales. The red‐edge spectral region is sensitive to variations in Chlleaf. An increasing number of sensors are capable of sampling red‐edge bands, providing opportunities to estimate ...

The Photogrammetric Record, Volume 37, Issue 179, Page 260-284, September 2022., 2022 Zhang et al. propose an improved multi‐task pointwise network to simultaneously segment instances (that is, individual roof planes) and semantics (that is, groups of roof planes with similar geometric shapes) in point clouds. A new roof data‐set (called RoofNTNU) is established by taking standard airborne laser scanning (ALS) point clouds as training ...

Are ecophysiological adaptive traits decoupled from leaf economics traits in wetlands?
Functional Ecology, Volume 33, Issue 7, Page 1202-1210, July 2019., 2019 Plain Language Summary Abstract Wetland plants have developed a suite of traits, such as aerenchyma, radial oxygen loss and leaf gas films, to adapt to the wetland environment characterised by, for example, a low redox potential and a lack of electron acceptors.

Development of New Ultrasonic Flow Meter [PDF]
, 2015 过去，机械流量计和电磁流量计占据了国内流量计市场的绝大多数份额。但是，二者都存在着致命的缺陷，比如寿命短、流体质量要求高等，这些缺陷阻碍了流量计性能的进一步提升。近些年，超声波流量计在流量测量仪器领域所发挥的作用越发重要。相比于其它流量计，超声波流量计维护方便、寿命长等特点使其更能满足市场需求。最重要的是，它更容易获得高精度的测量结果。 随着超声波流量计在工业和商业领域得到越来越广泛的应用，也就越来越迫切地需要提高其测量性能。为了改进超声波流量计的测量稳定性，本文设计了一种圆管和方管相结合的新型流量管 ...

Overreliance on Orthographic Similarity in L2‐Japanese Conceptual Processing by L1‐Chinese Learners
International Journal of Applied Linguistics, EarlyView.ABSTRACT Orthographic and phonological similarities between first (L1) and second (L2) languages can facilitate L2 processing. Particularly, L1‐Chinese learners of L2‐Japanese can benefit from the shared morphosyllabic Chinese characters (Japanese kanji/Chinese hanzi) because of their similar orthographies.
