摘要：
Plants and animals recognize microbial invaders by detecting pathogen-associated molecular patterns (PAMPs) through pattern-recognition receptors (PRRs). This recognition plays a crucial role in plant immunity. The newly discovered protein in plants that responds to bacterial flagellin, i.e., flagellin-sensitive 2 (FLS2), is ubiquitously expressed and present in many plants. The association of FLS2 and BAK1, facilitated by a highly conserved epitope flg22 of flagellin, triggers such downstream immune responses as activated MAPK pathway and elevated reactive oxygen species (ROS) for bacterial defense and plant immunity. Here we study the intrinsic dynamics and conformational change of FLS2 upon the formation of the FLS2–flg22–BAK1 complex. The top intrinsic normal modes and principal structural fluctuation components are very similar, showing two bending modes and one twisting mode. The twisting mode alone, however, accounts for most of the conformational change of FLS2 induced by binding with flg22 and BAK1. This study indicates that flg22 binding suppresses FLS2 conformational fluctuation, especially on the twisting motion, thus facilitating FLS2–BAK1 interaction. A detailed analysis of this sensing mechanism may aid better design on both PRR and peptide mimetics for plant immunity.
摘要：
The crystal structure of WO3 is orderly arranged with WO6 structure, possessing crystal channels for convenient charge transfer and ion diffusion. Using effective strategies to broaden the crystal channels of this materials can improve the charge transfer and ion diffusion. In this work, we have facilely utilized a sample hydrogenation method to introduce distorted WO6 structures into the crystal of tungsten oxide, which leads to the crystal reconstruction and W5O14 formation with large crystal channels. Due to the existence of large crystal channels, as-fabricated W5O14 nanosheet arrays achieve a high specific capacitance of 1352 mF cm(-2) (524 F g(-1)) at current density of 1 mA cm(-2), much higher than that of WO3. In addition, W5O14 nanosheet arrays also exhibit good stability with 84% capacitance retention after 4000 cycles. Finally, the high energy and power density of the asymmetric full supercapacitor W5O14//RuO2 device shed light on the potentially commercial application of W5O14. (C) 2019 Elsevier Ltd.

摘要：
Experimental measurements in pA collisions indicate no \({\text {D}}\) meson suppression (\(R_{{{\text {p}}\text {Pb}}} \sim 1\)) but a surprisingly large \(v_2\). To better understand these results we propose a system size scan at the LHC involving \(^{16}{\text {OO}}\), \(^{40}{\text {ArAr}}\), \(^{129}{\text {XeXe}}\) and \(^{208}{\text {PbPb}}\) collisions. Using Trento+ v-USPhydro+DAB-MOD to make predictions, we find that the \(R_{\text {AA}}\) tends towards unity when the system size is decreased, but nonetheless, in the most central collisions \(v_{2}\{2\}\) is almost independent of the colliding system. These results are analyzed in light of path length and initial eccentricity variations.

摘要：
The RNA tertiary structure is essential to understanding the function and biological processes. Unfortunately, it is still challenging to determine the large RNA structure from direct experimentation or computational modeling. One promising approach is first to predict the tertiary contacts and then use the contacts as constraints to model the structure. The RNA structure modeling depends on the contact prediction accuracy. Although many contact prediction methods have been developed in the protein field, there are only several contact prediction methods in the RNA field at present. Here, we first review the theoretical basis and test the performances of recent RNA contact prediction methods for tertiary structure and complex modeling problems. Then, we summarize the advantages and limitations of these RNA contact prediction methods. We suggest some future directions for this rapidly expanding field in the last.
摘要：
In this paper, an modified FitzHugh-Nagumo (FHN) neural model was employed to investigate the vibrational resonance (VR) phenomenon, the collective behaviors, and the transmission of weak low-frequency (LF) signal driven by high-frequency (HF) stimulus under the action of different electromagnetic induction in single FHN neuron and feed-forward feedback network (FFN) system, respectively. For the single FHN system, by increasing the amplitude of HF stimulus, the phenomena of vibrational mono-/bi-resonance are observed, and the input weak signal and output of system are synchronized, and the information of the weak LF signal is amplified. For the FFN system, the phenomena of vibrational mono-/bi-resonances are also occurred, both frequency and amplitude of the HF stimulus play an important role in the vibrational bi-resonances and transmission of weak LF signal in the FHN neural FFN.

摘要：
The rovibrational spectrum of the Ne–NO(X2Π) open-shell complex has been measured in the 5.3 µm region using distributed feed-back quantum cascade lasers to probe the direct absorption in a slit-jet supersonic expansion. Three P-subbands (P′ ← P″: 1/2 ← 1/2, 3/2 ← 1/2, and 5/2 ← 3/2) were observed, where P is the projection of the angular momentum J along the inertial a-axis of the complex. The hyperfine structure due to the nuclei spin of 14N (I = 1) was partially resolved in the P′ ← P″: 1/2 ← 1/2 and 3/2 ← 1/2 subbands. The observed mid-infrared spectrum of Ne–NO (X2Π) together with the previously reported microwave spectrum was analyzed using a modified semirigid asymmetric rotor Hamiltonian for a planar open-shell complex. The band origin is located at 1876.0606(97) cm−1, which is blue-shifted from that of the NO monomer by only 0.0888 cm−1. The complex shows strong structural relaxation upon excitation of the overall rotation and the internal rotation of the NO subunit.

摘要：
Mobile network performance and user Quality of Experience (QoE) will be negatively affected by the explosion of mobile data traffic. Recent research has focused on local caching at the wireless edge, as motivated by the 80/20 rule regarding content popularity. By caching popular contents at base stations (BSs), backhaul congestion and content access latency can be dramatically reduced. To address the limited storage size of BSs, an algorithm optimizing cooperative caching has been highlighted. Contents requested by mobile users that cannot be obtained locally could be transferred by cooperative BSs. In this paper, we propose a cooperative caching algorithm based on BS content access patterns. We use tensor decompositions with distance constraint to analyze interaction between users, contents and base stations. Thus, BSs with small geographical distances and similar content access patterns constitute a cooperative caching domain. Simulation results based on a real dataset of usage detail records (UDRs) demonstrate the superior performance and promising practical gains in caching of the proposed caching method compared to user clustering and BS clustering.

摘要：
The proton transfer reaction H3+ + CO → H2 + HCO+/HOC+ is of great importance in interstellar and circumstellar environments. The dynamics and kinetics of the reaction were studied using the quasiclassical trajectory approach on a newly developed ab initio potential energy surface (PES) for the ground electronic state. The PES was constructed by fitting 46 462 ab initio points at the level of CCSD(T)-F12a/aug-cc-pVTZ using the fundamental invariant-neural network method. The calculated product branching ratio, scattering angular distribution, and thermal rate coefficient agreed reasonably well with the experimental measurements, which were rationalized by the underlying reaction mechanisms.
