ABSTRACT Specific light wavelengths can affect plant responses to pathogens. In this study, we investigated the soft rot resistance of lettuce grown under different conditions and analyzed underlying molecular mechanisms using RNA‐seq data. The results revealed that blue‐light‐grown leaves had a better infection compared white other conditions, as evidenced by fewer symptoms lower incidence. After infection, H 2 O levels increased in all samples but were lowest leaves. Significantly higher...
We statistically investigate convective earthward fast flows (V⊥ > 200 km/s) using data measured by the Acceleration, Reconnection, Turbulence, and Electrodynamics of Moon’s Interaction with Sun (ARTEMIS) mission in tail plasma sheet during 2011-2022. Statistical results show that under penetration induction dusk-dawn interplanetary magnetic field component (IMF By), magnetotail By aligned direction IMF on average dominates entire investigated near-lunar region,...
Abstract The role of whistler-mode waves in the solar wind and relationship between their electromagnetic fields charged particles is a fundamental question space physics. Using high-temporal-resolution field plasma data from Magnetospheric MultiScale spacecraft, we report observations low-frequency whistler associated particle behavior Earth’s foreshock. frequency these close to half lower-hybrid (∼2 Hz), with wavelength ion gyroradius. electron bulk flows are strongly modulated by waves,...
Abstract The Earth's magnetopause is highly variable in location and shape modulated by solar wind conditions. On 8 March 2012, the ARTEMIS probes were located near tail current sheet when an interplanetary shock arrived under northward magnetic field conditions recorded abrupt compression at ∼(‐60, 0, ‐5) R E Geocentric Solar Ecliptic coordinate deep magnetotail. Approximately 10 minutes later, crossed many times within hour after oblique passed by. velocity vector downstream from was not...
Abstract The Advanced Small Analyzer for Neutrals (ASAN) on board the Chang’E-4 Yutu-2 rover first detected energetic neutral atoms (ENAs) originating from lunar surface at various local times farside. In this work, we examine ENA energy spectra, obtained in 23 days 2019 January 11 to 2020 October 12, and find a higher differential flux dawnside than duskside. Combined with Acceleration, Reconnection, Turbulence Electrodynamics of Moon’s Interaction Sun (ARTEMIS) data, analyze correlation...
Abstract In this study, we investigate ionospheric responses, including currents and aurorae, to solar wind dynamic pressure (SW P dyn ) sudden increases, which are critical for understanding wind‐magnetosphere‐ionosphere coupling. We focus on two similar SW pulse events that occurred January 24, 2012 November 12, 2010. both cases, equivalent (EIC) vortices were generated within about 10 min after the arrival, with a counter‐clockwise rotating vortex (viewed from above) observed dusk side in...
ABSTRACT Observations provide direct evidence for a sustained decline in solar activity since the 1980s, with minimum between cycles 24 and 25 (P24/25) reaching its deepest trough past hundred years. In response to reduced modulation, low-energy (<GeV) galactic cosmic rays (GCRs) at 1 au attain historical new highs P24/25, while anomalous (ACRs) show very inconsistent variations GCRs. To better understand long-term ACR variations, we revisit 6.0–13.4 MeV nuc−1 oxygen measurements from...
<title>Abstract</title> PCV2 and PRRSV are involved in a variety of disease syndromes, collectively referred to as Porcine Circovirus Associated Disease (PCVAD) Respiratory Complex (PRDC). To explore the effects other pathogens on porcine PCVAD PRDC. This study firstly conducted an epidemiological investigation PPV, confirmed prevalence PPV sub-types China; We then determined that were more common POS-PCV2 (PCV2 positive pathogen detection rate) than NEG-PCV2 (other rate negative); however,...
<title>Abstract</title> In regions of the solar system distant from planetary magnetic fields, galactic cosmic rays (GCRs) have generally been assumed to be uniformly distributed throughout interplanetary space. However, our analysis data Chang’E-4 lander revealed a region reduced GCR flux in pre-noon sector lunar orbit. Further investigation suggests presence an energetic particle cavity, formed by Earth’s field acting as obstacle propagation. This cavity indicates that influence within...
Abstract The propagation characteristics of hot flow anomalies (HFAs) near the Earth's bow shock are investigated, using observations from Cluster spacecraft. A data set comprised 19 classic HFAs (associated with tangential discontinuities, TDs) and 23 spontaneous (SHFAs, formed in absence solar wind discontinuities) was analyzed. For each event, velocity normal leading trailing HFA edges were calculated multiple multi‐point satellite analysis methods. HFAs, 93% events have edge (LE)...

Combining with ARTEMIS (P1 and P2) Wind data, we have investigated the magnetic field plasma properties in distant magnetotail during period January to December 2012. Of particular interest is their characteristic of density near neutral sheet. We present discovery high speed flow tail under northward interplanetary (IMF) conditions. Multi-satellite observations can tailward accompany when satellites were crossing sheet north ecliptic plane active condition. And this case, single satellite...

利用WIND和ARTEMIS卫星观测数据，分析远磁尾磁层顶对行星际和太阳风变化的响应，尤其是偏离日地连线的太阳风速度改变对远磁尾磁层顶的影响.研究发现在2011年9月13日的事件中，P2卫星观测到高速且高密度的磁鞘流.利用最小变量法进行分析发现，磁层顶沿着偏离日地连线的太阳风速度方向发生偏转.根据相似三角形定理，推断出本次事件中磁层顶在<i>y</i>方向和<i>z</i>方向上的偏转幅度分别达到10<i>R</i><sub>e</sub>和6<i>R</i><sub>e</sub>.P1和P2卫星的相对位置也证实了这一观点.因此，偏离日地连线的太阳风速度对远磁尾磁层顶的位形影响很大.研究结果可为建立包含太阳风速度<i>v</i><sub><i>y</i></sub>和<i>v</i><sub><i>z</i></sub>效应的磁层顶模型提供观测证据.
