Search-based Automatic Repair for Fairness and Accuracy in Decision-making Software.

Decision-making software mainly based on Machine Learning (ML) may contain fairness issues (e.g., providing favourable treatment to certain people rather than others based on sensitive attributes such as gender or race).

Mutation analysis for evaluating code translation.

Source-to-source code translation automatically translates a program from one programming language to another. The existing research on code translation evaluates the effectiveness of their approaches by using either syntactic similarities (e.g.

[Effects of conservation tillage on soil water condition and winter wheat yield in farmland].

Conservation tillage is one of the most important agricultural management measures on soil water conservation and crop yield increments. Based on long-term experiment during 2011 to 2016, effects of different tillage treatments, including conventional tillage, no-tillage and subsoiling treatments, on soil water condition, crop yield and water use efficiency were analyzed. The results showed that the average and relative soil water conservation rate was 7.

[Foliar water use efficiency of Platycladus orientalis of different canopy heights in Beijing western mountains area, China].

In this study, we focused on Platycladus orientalis, a widely distributed tree species in Beijing western mountains area, and precisely determined its foliar water use efficiency (including instantaneous water use efficiency derived from gas exchange and short-term water use efficiency obtained on carbon isotope model) by carefully considering the discrepancies of meteorological factors and atmosphere CO concentration and δC among different canopy heights, hoping to provide theoretical basis for carbon sequestration and water loss in regional forest ecosystem, and offer technical support for regional forest management and maintenance. The results showed that the foliar instan-taneous water use efficiency tended to increase with the increasing canopy height, following the order of the upper canopy > the middle canopy > the lower canopy. A variety of meteorological factors synergistically influenced stomatal movement, and stomatal conductance would in turn have an effect on foliar instantaneous water use efficiency.

[Growth characteristics of different tree species in shelterbelts in the depression area of Hebei Province, China.].

This research investigated shelterbelt structure indices using the standard sampling method, to study the dynamic changes of different tree species including Ulmus pumila, Populus simonii and Pinus tabuliformis in the depression area in Xiaobazi Township of Fengning County, Hebei Province, China. The results showed that the average age of U. pumila, P.
