Global warming increases the risk of high-temperature injury to maize. Inter- and mixed-cropping maize varieties with different genotypes is one way effectively alleviate during flowering period. However, mitigation effect intercropping modes on still unclear. Based previous years field production, Denghai 605, which more sensitive high temperatures period, was determined as main test variety, ...

Watermelon is susceptible to Fusarium wilt in successively mono-cropped soil. Pot experiments were carried out to investigate the effect of intercropping with aerobic rice on Fusarium wilt in watermelon. The tested soil was classified as a loam soil, previously planted with watermelon and collected from Hexian county, Anhui province, China. The results obtained are listed as follows: (1) 66.7% ...

Host legumes can enrich their immediate soil environment with rhizobia through rhizosphere effects. The extent to which this enrichment occurs, the specificity of the process and its interaction with soil management factors remain poorly described. In a series of field trials, we measured changes in the size of indigenous populations of Bradyrhizobium in response to cropping of host and non-hos...

abstracts should not cite references, nor refer to figures or tables. The reference to Ritchie et al 2001 has been removed from the abstract on Page 2. Minor revisions (we can make these changes for you, although it will speed up publication of your manuscript if you do them while making the major changes above) Author Contributions: Please confirm that all authors read and approved the final m...

The objective of this paper is to introduce a novel face database. It is composed of face images taken in real-world conditions and is freely available for research purposes at http://ufi.kiv.zcu.cz. We have created this dataset in order to facilitate to researchers a straightforward comparison and evaluation of their face recognition approaches under “very difficult” conditions. It is composed...

In this study, effects of continuous cropping on soil properties, enzyme activities, and relative abundance, community composition and diversity of fungal taxa were investigated. Rhizosphere soil from field continuously cropped for one-year, three-year and five-year by Coptis chinensis Franch. was collected and analyzed. Illumina high-throughput sequencing analysis showed that continuous croppi...

As the world's population increases, marginal lands such as drylands are likely to become more important for food production. One proven strategy for improving crop production in drylands involves shifting from conventional tillage to no-till to increase water use efficiency, especially when this shift is coupled with more intensive crop rotations. Practices such as no-till that reduce soil dis...

Existing person re-identification (re-id) methods assume the provision of accurately cropped person bounding boxes with minimum background noise, mostly by manually cropping. This is significantly breached in practice when person bounding boxes must be detected automatically given a very large number of images and/or videos processed. Compared to carefully cropped manually, auto-detected boundi...

The present study aims to replicate and extend Rule and Ambady (2010a)'s findings that Republicans and Democrats could be differentiated by face. In Experiment 1, undergraduates categorized 50 gray-scale full-face photos of candidates of the two major political parties in Taiwan, the Kuomingtang (KMT) and the Democratic Progressive Party (DPP). Using identical stimuli and procedure, Experiment ...

This study presents a crop planting and type proportion (CPTP) method for crop acreage estimation of complex and diverse agricultural landscapes. CPTP has three major components: (1) Crop planting proportion (CPP), estimated with wide-swath satellite remote sensing data to completely cover the monitoring area by segmenting cropped and non-cropped areas through unsupervised classification. (2) C...
