Climate variability and simultaneous breadbasket yield shocks as observed in long-term yield records
Climate variability breadbasket yield shocks yield records
2024/4/1
That climate variability and change can potentially force multiple simultaneous breadbasket crop yield shocks has been established. But research quantifying the mechanisms behind such simultaneous sho...
Long-Term Soil Fertility and Site Productivity in Stem-Only and Whole-Tree Harvested Stands in Boreal Forest of Quebec (Canada)
forest biomass whole-tree harvesting soil productivity site quality index soil provinces
2023/12/19
Using residual biomass from forest harvesting to produce energy is viewed increasingly as a means to reduce fossil fuel consumption. However, the impact such practices on soil and future site producti...
Rosin modified aminated mesoporous silica adsorbed tea tree oil sustained-release system for improve synergistic antibacterial and long-term antibacterial effects
TTO antibacterial evaluation mesoporous silica rosin sustained release
2023/12/5
Tea tree oil, a natural antibacterial compound, cannot be used effectively because of its volatile nature. In this work, a biocompatible carrier was prepared and loaded with tea tree essential oil. Th...
A Planted Forest Mapping Method Based on Long-Term Change Trend Features Derived from Dense Landsat Time Series in an Ecological Restoration Region

2023/12/1
Planted forests provide a variety of meaningful ecological functions and services, which is a major approach for ecological restoration, especially in arid areas. However, mapping planted forests with...
The extension of the long-term exclusive nuclear fuel supply arrangements between Bruce Power and Cameco for an additional 10 years through to 2040 secures decades of nuclear energy supply. The announ...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：An active contour model with local variance force term and its efficient minimization solver for multi-phase image
局部方差力项 活动轮廓模型 多相图像 最小化求解器
2023/5/8
In this work, we propose an active contour model with a local variance force (LVF) term that can be applied to multi-phase image segmentation problems. With the LVF, the proposed model is very effecti...

A decline in soil quality is a major factor contributing to the degradation of forest ecological function. Vegetation plays a vital role in maintaining soil quality; however, the influence of plantati...
k-root-n: An efficient O(√n) algorithm for avoiding short term double spending in Distributed Ledger Technologies such as Blockchain
Blockchain bitcoin distributed ledger technology
2019/7/17
Blockchains such as bitcoin rely on reaching global consensus for the distributed ledger, and suffer from a well know scalability problem. We propose an algorithm which can avoid double spending in th...
On the Complexity of non-recursive $n$-term Karatsuba Multiplier for Trinomials
Bit-parallel multiplier nn-Karatsuba algorithm shifted polynomial basis
2019/2/27
In this paper, we continue the study of bit-parallel multiplier using a nn-term Karatsuba algorithm (KA), recently introduced by Li et al. (IEEE Access 2018). Such a nn-term KA is a generalization of ...
