    Abstract Gray leaf spot of maize (Zea mays L.) is an important foliar disease in many parts of China. The causal organism of gray leaf spot in China is generally regarded as Cercospora zeae-maydis (3). In October 2011, symptoms similar to gray leaf spot were observed on 77% of maize plants in 25 locations (about 3,000 ha.) of Yunnan Province, China, and the disease could cause yield losses of 35 to 50%. The symptoms of leaf spot were different from those caused by C. zeae-maydis. The lesions on leaves were oblong, pale gray to pale brown, 2 to 3 × 5 to 40 mm, and confined by leaf veins that eventually coalesced. To identify the pathogen, 75 leaf samples were collected from 25 fields (three leaf samples for each field) at the kernel maturity stage. Single, well-separated lesions were excised and surface-sterilized by placing them in 75% ethanol for 5 s, then disinfested in 2% sodium hypochlorite for 5 min and rinsed with sterilized water. The lesions were incubated on water agar (WA) at 24°C for 48 to 72 h to allow sporulation. Seventy-five single-conidial isolates were obtained and cultured as described in Crous (1). Morphology of the isolates was determined on plates containing maize leaf powder agar (MLPA). After 5 days, isolates produced pale brown mycelia that consisted of 3- to 4-μm-wide, septate, branched hyphae. Conidiophores were 5 to 7 × 55 to 100 μm, straight to slightly flexuous, and usually 1- to 5-septate. Conidia were average 7.5 × 68 μm, fusiform, apex subobtuse, base subtruncate, and 3- to 6-septate. These characteristics are similar to C. zeina (2). The internal transcribed spacer (ITS) region of rDNA was amplified from each of the 75 isolates using primers ITS1/ITS4 and sequenced. The same sequences were obtained and the sequence of isolate YNGLS was submitted to GenBank (Accession No. KC878692). BLAST analysis of the sequence showed 100% confirmation to C. zeina (DQ185081). Additionally, a PCR-based diagnostic test using species-specific primers (2) confirmed the identification of the 75 isolates as C. zeina. The pathogenicity of the isolates was tested on greenhouse grown maize variety Huidan 4. The test was performed on 40 plants and replicated three times. The plants were inoculated at the 10 leaf stage by injecting 2 ml of conidial suspensions (2,500 conidia ml

    Abstract Voice interfaces has become an integral part of our lives, with the proliferation of smart devices. Today, IoT devices mainly rely on microphones to sense sound. Microphones, however, have fundamental limitations, such as weak source separation, limited range in the presence of acoustic insulation, and being prone to multiple side-channel attacks. In this paper, we propose RadioMic, a radio-based sound sensing system to mitigate these issues and enrich sound applications. RadioMic constructs sound based on tiny vibrations on active sources (e.g., a speaker or human throat) or object surfaces (e.g., paper bag), and can work through walls, even a soundproof one. To convert the extremely weak sound vibration in the radio signals into sound signals, RadioMic introduces radio acoustics, and presents training-free approaches for robust sound detection and high-fidelity sound recovery. It then exploits a neural network to further enhance the recovered sound by expanding the recoverable frequencies and reducing the noises. RadioMic translates massive online audios to synthesized data to train the network, and thus minimizes the need of RF data. We thoroughly evaluate RadioMic under different scenarios using a commodity mmWave radar. The results show RadioMic outperforms the state-of-the-art systems significantly. We believe RadioMic provides new horizons for sound sensing and inspires attractive sensing capabilities of mmWave sensing devices

    Abstract Speech enhancement and separation have been a long-standing problem, especially with the recent advances using a single microphone. Although microphones perform well in constrained settings, their performance for speech separation decreases in noisy conditions. In this work, we propose RadioSES, an audioradio speech enhancement and separation system that overcomes inherent problems in audio-only systems. By fusing a complementary radio modality, RadioSES can estimate the number of speakers, solve source association problem, separate and enhance noisy mixture speeches, and improve both intelligibility and perceptual quality. We perform millimeter-wave sensing to detect and localize speakers, and introduce an audioradio deep learning framework to fuse the separate radio features with the mixed audio features. Extensive experiments using commercial off-the-shelf devices show that RadioSES outperforms a variety of state-of-the-art baselines, with consistent performance gains in different environmental settings. Compared with the audiovisual methods, RadioSES provides similar improvements (e.g., ~3 dB gains in SiSDR), along with the benefits of lower computational complexity and being less privacy concerning.

    Abstract Previous studies on cone/seed traits of conifer seed orchards have focused on genetic variation, while non-genetic variation has rarely been investigated. This study examined the variation of cone/seed traits in a red pine clonal seed orchard in 2008 and 2018. The registered cone traits included size, weight, the number of seeds⁻ᶜᵒⁿᵉ, number of scales⁻ᶜᵒⁿᵉ and number of cones⁻ᵗʳᵉᵉ and seed traits included size, weight, kernel weight and shell thickness. For cone traits other than cone size in 2018, which were under strong genetic control, the variation was largely and similarly contributed by interramet and intercone variations. For seed traits, over 90% of the variation was due to non-genetic factors, with contributions from interseed intertree > intercone. While heritability estimates for cone size were high, those for other cone traits and all seed traits were low on broad-sense basis (0.10) but moderate on clonal mean basis (0.35). Genetic correlations between cone or seed traits were positively moderate to strong other than the number of cones⁻ᵗʳᵉᵉ, which correlated negatively with all other cone traits. The genetic correlations between cone and seed traits were weak, paired with mixed signs. The implications of these findings to manage seed orchards or advanced breeding were discussed.

    Abstract Arsenic is a naturally occurring element present in food, soil and water and human exposure is associated with increased cancer risk. Arsenic inhibits DNA repair at low, non-cytotoxic concentrations and amplifies the mutagenic and carcinogenic impact of other DNA-damaging agents, such as ultraviolet radiation (UVR). Arsenic exposure leads to oxidation of zinc coordinating cysteine residues, zinc loss and decreased activity of the DNA repair protein poly(ADP)ribose polymerase (PARP)-1. Because arsenic stimulates NADPH oxidase (NOX) activity leading to generation of reactive oxygen species (ROS), the goal of this study was to investigate the role of NOX in arsenic-induced inhibition of PARP activity and retention of DNA damage. NOX involvement in the arsenic response was assessed in vitro and in vivo. Keratinocytes were treated with or without arsenite, solar-simulated UVR, NOX inhibitors and/or isoform specific NOX siRNA. Knockdown or inhibition of NOX decreased arsenite-induced ROS, PARP-1 oxidation and DNA damage retention, while restoring arsenite inhibition of PARP-1 activity. The NOX2 isoform was determined to be the major contributor to arsenite-induced ROS generation and DNA damage retention. In vivo DNA damage was measured by immunohistochemical staining and analysis of dorsal epidermis sections from C57BI/6 and p91phox knockout (NOX2

    Abstract Liver cancer is a common malignant tumor. Although the overall incidence and mortality rates of liver cancer has been decreasing in recent years, the incidence of nonalcoholic fatty liver disease (NAFLD)-associated liver cancer tends to increase. The health and social issues brought by NAFLD-associated liver cancer have attracted more and more attention, and its epidemiology, pathogenesis, and diagnosis and treatment await further research. This article summarizes the current epidemiology and pathogenesis of NAFLD-associated liver cancer.
