To address the issue of temperature cross-sensitivity in refractive index （RI） measurement， a fiber-optic Surface Plasmon Resonance （SPR） sensor based on dual D-shaped no-core fiber （NCF） is proposed and designed. The sensor mainly consists of D-shaped NCF， Ag/Fe2O3composite film， and polydimethylsiloxane （PDMS）， where the silver and Fe2O3are successively coated on both D-shaped surfaces of NCF to generate SPR and enhance the oxidation resistance. The layer of PDMS coated on one D-shaped surface acts as a tunable ambient medium sensing the temperature variation and affecting the transmission spectrum of the sensor. Since the surface plasmon waves are excited in the two D-shaped surfaces with different films， the two RI and temperature-dependent spectral resonance peaks with different wavelengths will be produced. Research results demonstrate that the two peaks’ wavelengths have different responses to the variations of ambient RI and temperature. In the refractive index range of 1.36-1.376 and temperature range of 10-100 °C， the RI and temperature sensitivities reach to 5000 nm/RIU and -0.546 nm/°C， respectively. With the sensitivity coefficient matrix， simultaneous measurement of refractive index and temperature can be realized， and the corresponding accuracy is superior to 0.4×10-5RIU and 0.037°C.

Dear Editor,This letter studies the bipartite consensus tracking problem for heterogeneous multi-agent systems with actuator faults and a leader's unknown time-varying control input. To handle such a problem, the continuous fault-tolerant control protocol via observer design is developed. In addition, it is strictly proved that the multi-agent system driven by the designed controllers can still achieve bipartite consensus tracking after faults occur.

In this paper， CdxZn1-xS thin films were deposited on glass substrates by chemical bath deposition （CBD），and the effects of different concentrations of ammonia water on the morphology， structure and optical properties of the films were studied. CdxZn1-xS thin films have hexagonal crystal structure， the transmittance is above 75% in the visible range， and the optical band gap is between 2.6 eV and 2.9 eV. The influence of the experimental group of deposited thin films on the performance parameters of the CIGS battery was studied by simulation with SCAPS-1D software and the cell efficiency reached 22.42%. It is introduced that the buffer layer prepared in this experiment is feasible in CIGS solar cells.

A nanocrystal-molecule complex composed of CdSe donor and Rhodamine B (RhB) acceptor is prepared to investigate the effect of accepter-donor ratio on the Fo?rster resonance energy transfer (FRET) process. To highlight the FRET process， the energy level alignment between CdSe and RhB is purposefully designed and CdSe nanocrystal is coated with a wide band-gap ZnS shell. The carrier dynamics is observed via combined spectral analysis. The results reveal clear FRET process between the CdSe donor and RhB acceptor. The FRET is enhanced by increasing RhB/CdSe ratio and a gradual saturation will be present at high RhB concentration.

采用离散元-有限差分耦合数值方法研究平行隧道间钢套管下旋施工的影响。根据工程实例建立数值模型,并通过对比模拟值与实测值验证了数值分析方法的合理性。数值模型分析了双隧道-静压、双隧道-旋压、单隧道-旋压等3种工况下隧道和土层的受力变形特性。结果表明:钢套管旋压施工导致隧道产生的横向位移为静压施工的163.5%,单隧道工况下的隧道横、竖向变形分别较双隧道工况增加32.7%和53.4%;旋压相较于静压可以有效减小管片的收敛变形,而单隧道工况的收敛变形为双隧道工况的2倍;旋压工况下,随钢套管沉入深度增加,旋转指数先增加后减小,最大值发生在套管下沉至隧道拱顶附近,而在静压工况下需重点关注竖向旋转引起的管片错位;对于双隧道-旋压工况,应重点关注施工初期由于土体水平位移引起的地层变位和施工后期土体竖向位移可能导致的机械倾覆和钢套管的垂直度误差;隧道管片应力分布区域及特征与钢套管动态施工过程紧密相关,应在不同阶段采用相应的管片补强措施。

The Pomacea canaliculata, also known as apple snail, is an invasive species in China, posing a serious threat to agricultural production and public health. To prevent its rampant infestation, we developed a highly efficient snail-killing lead compound, 1-(4-chlorophenyl)-3-(pyridin-3-yl)urea (PBQ). However, the killing mechanism of PBQ remains unclear. To elucidate this, two novel compounds, B-PBQ and J-PBQ, were developed through structural modification of PBQ and were used, through both protein pull-down assay and confocal laser scanning microscopy imaging, to identify and confirm that phosphofructokinase(PFK) in the apple snail is the primary target protein of PBQ. Further studies revealed that PBQ successfully inhibits the activity,content, and expression of PFK in apple snail, disrupting the glycolysis pathway and leading to abnormal energy *** disruptions impair the snail’s tolerance to low oxygen, resulting in its efficient eradication. These findings offer a promising direction for developing next-generation PFK-targeted snail-killing pesticides. Furthermore, the strategy of combining pull-down assays with optical imaging used in this work provides a novel approach for the exploration of mechanisms of other pesticide candidates.
