Plasmonic gap-enhanced Raman tag nanorods for imaging 3D pancreatic spheroids using surface-enhanced Raman spectroscopy and darkfield microscopy

Published: October 2020

Abstract
Plasmonic gap-enhanced Raman tags (GERTs) are new emerging nanoprobes that, based on their unique surface-enhanced Raman spectroscopy (SERS) signal, can play a major role in complex imaging and detection of biological systems. GERTs are generated from a metal core nanostructure and layered with one or more metal nanosized layers, encasing a Raman active molecule. The advantages of GERTs are enhanced surface plasmon and electromagnetic resonance, as well as inherent protection of the Raman active molecule from environmental deterioration that could reduce their spectroscopic signatures over time. In this study, we used in vitro three-dimensional (3D) spheroid cultures to demonstrate these advantages. 3D spheroids mimic the in vivo tumor microenvironment better than 2D culture, with abundant extracellular matrix and hypoxia inducing variability of pH and enzymatic reactions. Here, we report the use of GERTs in large pancreatic 3D spheroids (>500 μm in apparent diameter) for complex penetration visualization. Our combined imaging technique of enhanced darkfield microscopy and SERS was able to identify the presence and distribution of the GERTs within the 3D spheroid structure. The distribution of GERTs 2 hours after the nanorods’ incubation indicated accumulation, generally in the outermost layer of the spheroids but also, more randomly, in non-uniform patterns in deep layers of the 3D spheroids. These observations bring into question the mechanism of uptake and flow of the nanoparticles in function of their incubation time while demonstrating the promising potential of our approach. Additionally, the SERS signal was still detectable after 24 hours of incubation of GERTs with the 3D culture, indicating the stability of the Raman signal.

Abstract
A photonic crystal (PhC) based optical component paves a path to the upcoming all-optical computer processors. All the components can be realized with the help of PhCs. In particular, optical gates have played a major part in the development of all-optical half adders which has lead to the bloom of optical computing technology. In this paper, a PhC based optical half adder is proposed and a brief analysis is carried out for the different crystal structures and lattice patterns. The efficiency of the device is analyzed by providing proper distinct space in output power between logical ‘0’ and ‘1’ states and it operates well even in the reduced input power level. The error can be minimized while identifying the logical states (logic ‘0’ and logic ‘1’), by setting a threshold limit for output power. The threshold level is fixed such that if it is greater than 0.7 µW, it is considered as logic ‘1’, and if it is less than 0.35 µW, then it will be taken as logic ‘0’. The device with circular crystals in a hexagonal lattice provides a better contrast ratio of 12.55 dB and 9.29 dB for ‘sum’ and ‘carry’ respectively. The miniature size of the proposed device depicts that this device is compatible with photonic integrated circuit (PIC) applications.
Quasi-stationary states in temporal correlations for traffic systems: Cologne orbital motorway as an example
Authors: Wang Shanshan , Gartzke Sebastian , Schreckenberg Michael , Guhr Thomas 
Published: October 2020

Abstract
Traffic systems are complex systems that exhibit non-stationary characteristics. Therefore, the identification of temporary traffic states is significant. In contrast to the usual correlations of time series, here we study those of position series, revealing structures in time, i.e. the rich non-Markovian features of traffic. Considering the traffic system of the Cologne orbital motorway as a whole, we identify five quasi-stationary states by clustering reduced-rank correlation matrices of flows using the k-means method. The five quasi-stationary states with nontrivial features include one holiday state, three workday states and one mixed state of holidays and workdays. In particular, the workday states and the mixed state exhibit strongly correlated time groups shown as diagonal blocks in the correlation matrices. We map the five states onto reduced-rank correlation matrices of velocities and onto traffic states where free or congested states are revealed in both space and time. Our study opens a new perspective for studying traffic systems. This contribution is meant to provide a proof of concept and a basis for further study.
Universality of eigenvector delocalization and the nature of the SIS phase transition in multiplex networks
Authors: Ferraz de Arruda Guilherme , Méndez-Bermúdez J A , Rodrigues Francisco A , Moreno Yamir 
Published: October 2020

Abstract
Universal spectral properties of multiplex networks allow us to assess the nature of the transition between disease-free and endemic phases in the SIS epidemic spreading model. In a multiplex network, depending on a coupling parameter, p, the inverse participation ratio (IPR) of the leading eigenvector of the adjacency matrix can be in two different structural regimes: (i) layer-localized and (ii) delocalized. Here we formalize the structural transition point, p*, between these two regimes, showing that there are universal properties regarding both the layer size n and the layer configurations. Namely, we show that IPR ∼ n
−δ
, with δ ≈ 1, and revealed an approximately linear relationship between p* and the difference between the layers’ average degrees. Furthermore, we showed that this multiplex structural transition is intrinsically connected with the nature of the SIS phase transition, allowing us to both understand and quantify the phenomenon. As these results are related to the universal properties of the leading eigenvector, we expect that our findings might be relevant to other dynamical processes in complex networks.

Abstract
With the continuous development of the economy, environmental pollution has become more and more serious, especially water pollution. During and after the “Eleventh Five-Year Plan”, China’s environmental protection and ecological construction and restoration work will be fully carried out. Among them, water pollution control, air pollution, solid waste pollution, heavy metal pollution, radioactive pollution control, and desertified land control are environmental protection and ecological, one of the very important contents of environmental construction. The purpose of this article is to study the application of lake and wetland ecological restoration technology in environmental pollution control and ecological restoration. Commonly used domestic lake pollution treatment methods include: microbial method, dredging and salvage, chemical sedimentation (flocculation), physical measures (filtration and membrane), constructed wetland, reoxygenation (micropores, turbulent aeration), mechanical dilution transfer (flushing) Water, water change) etc. The microbiological method is to put in microorganisms, the use of microbial preparations can digest and degrade organic pollutants and remove the purification mechanism of ammonia nitrogen and phosphorus, so as to achieve the goal of various water pollution control. And its disadvantage is that it can’t last forever. Ecosystem restoration project: It is the process of using engineering technology to assist the restoration of an ecosystem that has been degraded, destroyed, newly built or rebuilt. Its application enables the ecosystem to be restored and strengthened in terms of its own health, integrity and sustainability. Once the ecological restoration project is completed, the ecosystem does not need to be maintained by humans, as long as it is prevented from degrading due to disturbance. This is similar to the microbiological method in the lake and wetland ecological restoration technology.

Published: October 2020

Abstract
Water environment is a typical public goods. When the market fails, government intervention is needed at this time. The local environmental protection department should strengthen supervision of enterprises, comprehensively investigate enterprises and factories in the river basin that do not meet environmental protection requirements and carry out rectification within a specified period of time for units that have not entered the unified sewage pipe network. At the same time, strengthen inspections and pay close attention to secret discharge and leakage. On the other hand, it is necessary to strengthen public supervision, establish and build a public participation mechanism and give full play to the consciousness and enthusiasm of the people, so as to stop and resist pollution and highlight the power of the public. At present, only relying on manual treatment can no longer meet the needs of river basin development. Especially after the completion of large-scale water resources network planning and construction, water basin planning has become an important problem that needs to be solved urgently. GIS technology integrates functions such as remote sensing mapping, terrain perception, etc. and has long been used in watershed planning in developed countries. This article analyzes it.

Authors: Wang Mengwen 
Published: October 2020

Abstract
Under the background of China’s rigid population growth and the reduction of cultivated land area, the degree of agricultural intensification has been increasing. Pesticides and fertilizers have greatly increased crop yields. However, the large amount of agricultural chemicals input leads to the decline of soil and environmental quality. The environmental pollution caused by agricultural activities is increasing, especially in the high intensive agricultural areas with high land use intensity and a large amount of agricultural chemicals input. Agricultural land use is facing the dual challenges of ensuring food security and ecological environment security, which is an arduous and urgent task to realize the sustainable and healthy development of China’s agricultural countryside. High intensive agriculture gains higher economic benefits, but it also leads to serious environmental consequences. In the face of the increasingly serious problems of agricultural ecological environment, how to guarantee the economic development and control the environmental risk of agricultural land use is an urgent practical problem. Based on this, this paper uses computer technology to analyze the environmental risk control strategy of highly intensive agricultural land use based on the landscape scale.

Abstract
The main chemical components of GCr15 bearing steel are Fe, Cr, C, Mn, etc., which are mainly used to produce bearing rings, rolling elements and other rolling bearing manufacturing industries. After more than one hundred years of development, GCr15 material is used for manufacturing bearing components, and it is called “heart of industry” because GCr15 material is one of the best quality steels [1]. After heat treatment, GCr15 material steel has the “most extensive” practicality for various working conditions of the bearing, such as high load capacity, good fatigue resistance, strong wear resistance, and high hardness, better temperature adaptability and so on [2]. This paper first discusses the heat treatment process of GCr15 material, and then analyzes and studies the cracking phenomenon of a certain batch of 1m diameter GCr15 material bearing ring blanks after heat treatment, and focuses on the fracture morphology, chemical composition, microstructure and other phenomena. The analysis found the cause of the crack and improved the original heat treatment process, that is, before quenching, isothermal spheroidizing annealing is used and the spheroidizing annealing temperature is strictly controlled, bainite austempering is used to replace martensite quench tempering after quenching, and finally, the problem is solved through experimental verification.

Therefore, we must comprehensively adjust and tap the potential of FBR, which will achieve long-term stable production in the middle and late stage of fault block oilfield. Therefore, based on the characteristics and classification of FBR, this paper analyzes the development status in the middle and late stage. Then, according to the characteristics of fault block oilfield in the middle and late stage, this paper puts forward some comprehensive adjustment technical measures, which will better adapt to the reasonable development mode of FBR in the middle and late stage.

This paper mainly expounds the factors affecting rapid start-up such as the type of inoculating sludge, the amount of sludge, the hydraulic conditions and the bacteria start-up agent for hydrolytic acidifying bacteria. The start-up speed and operation effects of hydrolysis acidification process were improved by adjusting process parameters.
Effect of Mg on Microstructure and Mechanical Properties of Hypereutectic Al-25Si Alloy
Authors: Zhao Gaozhan , Chen Wen , Chai Shuxin , Li Ming , Tao Jianquan , Gao Shiqing 
Published: October 2020

Abstract
The effects of Mg Addition mode and amount on the microstructure and mechanical properties of hypereutectic Al-25Si alloy after modification were analyzed. The results show that the Mg2Si phase is relatively small, which is in the shape of granular or small bone, and has relatively little damage to the tissue; The hardness of the alloy is directly proportional to the amount of Mg added. When 1.5wt. % Mg is added, the microstructure and properties reach the best state. If the amount of Mg 2Si is excessive, it will gradually change into a coarse mesh, Chinese character shape and deteriorate the properties. The main reason is that there is a close adhesion growth relationship between Mg2Si and eutectic silicon. The modification and refinement lead to the lack of nucleation basement and the inhibition of growth of Mg2Si. At the same time, the modified residual AlP phase is used as the nucleation point. Mg2Si phase did not coarsen obviously, and other phases also maintained in a good shape.
