This study investigates the impact of silent and alerted failures on driver performance across two levels of scenario criticality during automated vehicle transitions of control.

Recent analyses of automated vehicle crashes show that many crashes occur after a transition of control or a silent automation failure. A substantial amount of research has been dedicated to investigating the impact of various factors on drivers' responses, but silent failures and their interactions with scenario criticality are understudied.

A driving simulator study was conducted comparing scenario criticality, alert presence, and two driving scenarios. Bayesian regression models and Fisher's exact tests were used to investigate the impact of alert and scenario criticality on takeover performance.

The results show that silent failures increase takeover times and the intensity of posttakeover maximum accelerations and decrease the posttakeover minimum time-to-collision. While the predicted average impact of silent failures on takeover time was practically low, the effects on minimum time-to-collision and maximum accelerations were safety-significant. The analysis of posttakeover control interaction effects shows that the effect of alert presence differs by the scenario criticality.

Although the impact of the absence of an alert on takeover performance was less than that of scenario criticality, silent failures seem to play a substantial role-by leading to an unsafe maneuver-in critical automated vehicle takeovers.

Understanding the implications of silent failure on driver's takeover performance can benefit the assessment of automated vehicles' safety and provide guidance for fail-safe system designs.

Its fruit are rich in omega-3 essential fatty acids, which are valuable nutritionally (Cheon et al, 2013). In March 2019, severe branch blight of walnuts (cv. Qingxiang) were observed in two fields in Ganquan Town, Gansu Province, China (N 33°56'/E105°44'). The incidence was about 3% among 10,000 walnuts. Disease symptoms included fusiform or oval black lesions gradually expanded on the branches, blight and dieback of branches, reddish brown dead branch bark with lots of black small spots (pycnidia), and defoliation. To isolate pathogen, 30 diseased tissues collected from different trees were disinfected with 0.1% HgCl solution for 1 min, rinsed in sterilized water 3 times, and placed on potato dextrose agar (PDA) at 25℃ in the dark. About three days later, 4 fungal isolates (3-3, 3-6, 3-9 and H3) with similar morphological characteristics were obtained. Their colonies, with regular margin on OA, 6.1~6.8 cm diam. after 7 days, were loose, greenish olfter two weeks, all inoculated plants still were asymptomatic, indicated that four isolates aren't B. exigua var. linicola. Therefore, they were identified as B. exigua var. exigua based on morphological characteristics, molecular analysis and pathogenicity tests. To our knowledge, this is the first report of B. exigua var. exigua causing walnut branch blight worldwide, which will provide further guidance for prevention and control of walnut branch blight.In August 2020, a New York State vegetable grower sought assistance to identify a malady of tomato (Solanum lycopersicum). The plants were grown from saved seed that had been planted annually in NY and/or FL for over 15 years without significant disease problems, but the identity of the cultivar was not known. Submitted photos showed severely stunted plants with distorted leaves (crinkling, cupping, twisting); leaves were reduced in size and showed interveinal yellowing. Although the most likely explanation given the growing region was herbicide damage, the symptoms bore a striking resemblance to those presented by tomato yellow leaf curl (TYLCV)-infected tomato plants. TYLCV has not been reported from NY, as the whitefly vector (Bemisia tabaci) does not overwinter in the region. Stem tissue from a symptomatic plant was grafted onto a greenhouse grown rootstock of tomato breeding line 201231 (Cornell University); shoots emerging from grafted rootstocks showed symptoms consistent with those on the scion withinment will depend on the epidemiology of the pathogen, in this case, the presence of the vector.Gynura japonica (Thunb.) Juel [Asteraceae; syn G. segetum (Lour.) Merr] is an important perennial medicinal herb used in China for topical treatment of trauma injuries (Lin et al. 2003). It grows naturally in the southern provinces of China and is also sometimes cultivated. During 2018-2020, wild G. japonica plants exhibiting chlorotic spots and mosaic symptoms were observed in Zhejiang province, China. To identify the possible causal agents of the disease, a single symptomatic leaf sample was collected in August 2019 and sent to Zhejiang Academy of Agricultural Sciences (Hangzhou, China) for next generation sequencing (NGS). Total RNAs extracted with TRIzol (Invitrogen, Carlsbad, USA) were subjected to high throughput sequencing on the Illumina NovaSeq 6000 platform with PE150bp and data analysis was performed by CLC Genomic Workbench 11 with default parameters (QIAGEN, Hilden, Germany). A total of 37,314,080 paired-end reads were obtained, and 11,785 contigs (961 to 10,964 bp) were generated and compared wiruit trees especially in the family Rosaceae, although there are recent reports that it can also infect some plants in Gramineae, Asparagaceae and Nelumbonaceae (Bhardwaj et al. selleck chemicals llc 2017; Chen et al. 2019; He et al. 2019). Our results provide the first report that Gynura is a natural host of CVB and ASGV. Further surveys and biological studies are underway to evaluate the importance of Gynura as a virus reservoir for epidemics among the various hosts.Apple valsa canker (AVC), caused by Valsa mali (Vm), is one of the most important diseases of apple trees in China. AVC occurred severely along with cold winter or cold spring. However, the effect of lower temperature on Vm is poorly understood. This study evaluated the influence of lower temperature pre-treatment of Vm on the infection of apple twigs and leaves. The results showed that exposing of Vm at lower temperature (between -10°C and 10°C) for more than 18 h significantly increased the disease severity of apple leaves and twigs, with a higher LAR, lesion length and DI than that at 25°C. In addition, cold treatment ranging from -5°C to 10°C promoted the colony growth. Meanwhile, the relative expression of four cell wall degrading enzymes (CWDEs) related genes pre-treated at -5°C and 5°C were significantly higher than that at 25°C. The results indicated that the virulence of Vm mycelium is sensitivity for lower temperature change. After sensing lower temperature changes, Vm can adjust its infection of apple trees by regulating the expression of pathogenicity gene and growth rate.
