Abstract
Charged particle radiotherapy is currently used in an increasing number of centres worldwide. While protons are the most widely used ion species, carbon ions have shown many advantages for the treatment of radioresistant tumours, thanks to their higher Linear Energy Transfer (LET) and Relative Biological Effectiveness (RBE). The complexity and the high cost of conventional carbon therapy facilities has stimulated the investigation of alternative acceleration approaches such as the processes based on high-power laser interaction with solid targets. Recent developments in ion acceleration have allowed to investigate for the first time the biological effects of carbon ions at ultra-high dose-rate (109-1010 Gy/s) using the GEMINI laser system at Rutherford Appleton Laboratory (RAL). Carbon ions were accelerated from ultrathin (10-20 nm) carbon foils and energy selected by a magnet allowing to irradiate the cells with an average carbon energy of 10 MeV/u ± 8%. A dosimetry approach specifically designed for these low-energy ions was employed, which was based on the use of unlaminated EBT3 Radiochromic films. The details of the dosimetry arrangement as well as the Geant4 simulation performed to predict the energy and the dose distribution at the cell plane will be reported.

Abstract
A proposal for building a new Free Electron Laser facility at the Laboratori Nazionali di Frascati, EuPRAXIA@SPARC_LAB, is at present under consideration. This FEL facility will exploit plasma acceleration to produce ultra-bright photon pulses with durations of few femtoseconds down to the wavelengths between 2 and 4 nm, in the so called “water window”. The main class of experiments to be performed will include coherent diffraction imaging, soft X-ray absorption spectroscopy, Raman and photofragmentation measurements. In this article we present the updates on the photon beamlines design for the facility.
Modeling of capillary discharge plasmas for wakefield acceleration and beam transport
Authors: Cook N M , Carlsson J , Moeller P , Nagler R , Tzeferacos P 
Published: September 2020

Abstract
Next generation accelerators demand sophisticated beam sources to produce ultra-low emittances with large gradients. The subsequent beamline optics are equally critical to transporting these beams between accelerating stages or to interaction points. Capillary discharge plasmas may address each of these challenges. Capillaries have been demonstrated as sources capable of increasing the peak energy and beam quality of laser wakefield accelerators, and as active plasma lenses featuring orders-of-magnitude increases in peak magnetic field. These systems are sensitive to energy deposition, heat transfer, ionization dynamics, and magnetic field penetration; therefore, improved modeling will enable advances in capillary design. We present simulations of capillary discharge waveguides and active plasma lenses in using FLASH, a publicly-available multi-physics code in development at the University of Chicago. We report on the implementation of a 2D, cylindrically symmetric capillary model for capturing plasma density and temperature evolution with realistic conductivities and magnetic fields. We then illustrate the use of laser energy deposition to model low density channel formation for the matching and guiding of intense laser pulses. Lastly, we discuss simulations of active capillary plasmas with different fill species, which show agreement with experimental observations of nonlinearities in the current density profile and magnetic field.

Abstract
We summarize the conclusions from Working Group 8 of the European Advanced Accelerator Concepts workshop in 2019 (EAAC2019) on the suitability and prospects for using advanced and novel accelerator (ANA) technology for future high-energy physics (HEP) applications. We identify the key technology gaps remaining for the main ANA approaches for building future e+/e− linear colliders and estimate the time scales needed to close them. We also identify synergistic development paths that can be leveraged to achieve key technology demonstration steps through non-HEP applications and through non-lepton-collider HEP applications.
Preliminary Results of an Experiment to Determine the Thickness of Snow Cover Using Ground Penetrating Radar and a Laser Rangefinder
Authors: Marchuk V N , Grigoryevsky V I , Byshevskii-Konopko O A 
Published: September 2020

Abstract
The article discusses the combination of a ground penetrating radar (GPR) with a laser rangefinder to determine the snow cover thickness, an experiment is described in accordance with the proposed methodology and a comparative analysis of the data obtained is carried out. The purpose of the proposed development of the combined method is to improve the accuracy of snow cover depth determination. Many tasks require high spatial resolution both in the horizontal coordinate and in the depth of the snow cover, since local excess of its critical level can lead to irreversible consequences. Such a situation can arise, for example, when avalanches come down in mountainous areas or when roofs of a large area collapse when snow accumulates on them. The accuracy of the snow depth determination obtained in the experiment is ∼ 10 cm and the resolution along the horizontal coordinate is ∼ 5 cm. The predicted distance based on the equipment used is about 500 meters. The proposed method can be used for determining the amount of snow on roofs of buildings and structures, as well as in predicting the descent of avalanches, and in search for hidden objects under the snow in emergency situations.

AbstractThe article raises the problem of fine tuning over-the-horizon radars with relevant information about the parameters of the ionosphere. To improve the accuracy of the radar, it is proposed to create a system of remote positions, which are ionosondes of vertical and inclined sensing. The results of the operation of such ionosondes serve to adjust the global model of the ionosphere. Thus, the quality of the radar is significantly improved, allowing more accurately determine the coordinates of air targets..

Authors: Bulkib V V , Tersin V V 
Published: September 2020

Abstract
The results of the development and experimental verification of a two-channel acoustic noise control data processing system that provides real-time control of non-deterministic broadband acoustic noise are presented. The system is implemented using the LabView graphical programming language G. The length of the measured realization is determined by the sample size ratio to the sampling frequency, and the number of measurements of each sound signal is determined by the ratio of the analysis time to the length of the measured realization. The measured realization of the audio signal in the form of 40,000 16-bit binary numbers is processed using the fast Fourier transform. As a result of processing, a discrete audio signal spectrum is obtained in the range from 0 to 20 KHz in steps of 1 Hz. To check the quality of the system’s functioning, a pair of microphone capsules of the MDN-318, wm61, etc. types, widely used in computer audio equipment, preliminarily selected according to the amplitude-frequency characteristics. The results of system verification using a laboratory acoustic chamber are presented. The advantage of the system is the receipt of a difference spectrum of controlled signals. The conclusion is drawn about the possibility of using this system for a qualitative assessment of changes in the noise level along the propagation path, as well as additions to the results of measurements performed by standard methods.
Analysis of seismic bidirectionality on response of reinforced concrete structures with irregularities of l-shaped plan and soft story
Authors: Sobrado V H , Yaranga R , Orihuela J D 
Published: September 2020

Abstract
The seismic design of buildings is usually performed using one-way analysis for each of main axes independently. However, seismic events have fairly random behaviour and impose bidirectional solicitations on structures. In this work, the study of the response in structures subjects to earthquake loads with irregularity of l-shaped plan and soft story is carried out. For this, the linear time-story analysis (LTHA) of these has been carried out imposing seismic solicitations in two orthogonal directions. Thus, the structural response with incidence angle variations of 10° is obtained and compared with the response derived from the unidirectional analysis. Variations of up to 50% and 72% are obtained for model structures with l-shaped plan and soft story respectively.
Experimental investigation into the failure process of exterior beam-column joints with high-strength reinforcements
Authors: Arshadi H , Kheyroddin A , Naderpour H , Kioumarsi M 
Published: September 2020

Abstract
Although using high-strength reinforcements (HSRs) have economical and execution benefits, their possible negative effects on the performance of structures such as ductility, energy dissipation, and damage process caused them to be restricted by building codes in seismic areas. In this research, the HSR effects on the cyclic behavior, cracking process, and damage indices of exterior beam-column joints were experimentally investigated under cyclic loading. Three exterior beam-column joints with HSRs (with the yield strengths of 500 and 580 MPa) were designed based on the special seismic provisions of ACI 318-19. These specimens were subjected to cyclic loading and their responses were obtained. The results showed that using HSRs led to increasing the width and depth of the cracks. Then, two methods of calculating damage indices (introduced by Promis et al., 2009) were applied based on the experimental results. Considering the damage indices, it was observed that using HSRs increased the damage indices of the specimens and the damage distribution in them.
Comparative analysis of the seismic response of an essential and a common building using site spectra and dynamic modal spectral analysis according to South American standards
Authors: Huaripata F , Torres J F , Orihuela J 
Published: September 2020

Abstract
The buildings built on coastal soil, located on the fire belt present a high seismic risk, since there are unfavorable soil conditions and in other cases plate subduction. This has led to countries located in these areas developing seismic regulations that allow the proper design of engineering works; however, various regulations present different considerations for the design, such as the use of parameters that allow standardizing the design that often does not present the same seismic responses of the real dynamic behavior of the soil. Therefore, the present research proposes to evaluate the seismic response of two buildings, one essential and the other common, with an analysis using site spectra, a dynamic spectral modal analysis and additionally a time-history analysis taking into account soil types and use of different seismic parameters of South American standards. The main result is that the seismic response by analysis with site spectra (ES) is greater compared to the dynamic spectral modal analysis according to the magnitude of the earthquakes and the type of soil.

Sensitivity Analysis of Designs of Row House Planning Influencing on Local Microclimate and Building’s Cooling Energy Consumption in A Tropical City
Authors: Jareemit D , Srivanit M 
Published: September 2020

Abstract
This study aims to investigate the impact of design characteristics of row house projects on outdoor thermal conditions and the building’s cooling energy consumption. The studied parameters comprise the design combinations of four street canyon orientations, building-two block shapes, four street canyon’s aspect ratios (H/W), and two window to wall ratios (WWR). The study firstly performs the simulations of air temperature and mean radiant temperature across the street canyons via using ENVI-met modeling. The simulated air temperature is used as input in energy modeling to calculate cooling energy consumption in a residential unit. The Standardized Regression Coefficient (SRC) obtained from the multiple regression analysis is used to determine the significant design parameters influencing on outdoor air temperature, mean radiant temperatures, and building’s cooling energy consumption. It is found that the increase of H/W has a positive effect on both outdoor conditions and building energy consumption. At the same time, the impact of street canyon’s orientation and building-block shape on those issues shows an invert direction. Future studies should investigate how to optimize the design for achieving better outdoor thermal conditions and building energy efficiency.

Abstract
The active chemical components and targets of rosa roxbughii tratt were screened by the method of network pharmacology, and the molecular mechanism of its action was discussed. By consulting relevant literature reports, we established drug-disease targets by using databases such as TCMSP, TCMIP, Genecards and OMIM. Using STRING database to construct the protein interaction network between rosa roxbughii tratt and cancer target; and Cytoscape software was used to construct the interactive network diagram of “active ingredient-target-disease”. The function enrichment analysis of Gene Ontology (GO) and pathway enrichment analysis based on Kyoto Encyclopedia of genes and genomes (KEGG) were carried out by using biological information annotation database (David). We obtained 11 active components and 80 drug-disease targets were obtained, DAVID database was used to carry out GO function enrichment analysis and KEGG pathway enrichment analysis on 80 potential targets, and 303 biological processes and 114 signaling pathways were screened out to participate in the anti-cancer effect of rosa roxbughii tratt. The Pathway in cancer has the strongest correlation with cancer, which is related to the regulation of IL6, AR, CASP3 and other key genes. These key genes are related to myricetin, quercetin, kaempferol and other compounds in rosa roxbughii tratt. The anti-cancer compounds of rosa roxbughii tratt might were myricetin, quercetin, kaempferol and other compounds. The anti-cancer effect of rosa roxbughii tratt may regulation of key genes, indirectly affecting the sustained angiogenesis, developing apoptosis and promotion, so as to promote or inhibit the production of cancer.
Influence research of weak layer on slope sliding mode and stability
Authors: Li Ang , Li Wenli 
Published: September 2020

Abstract
Weak layer is an important factor leading to slope instability, which cannot be ignored in slope stability analysis. In order to explore the influence of weak layers on the slope slip mode and stability of the slope, this paper selects typical open-pit mine slopes containing weak layers as the engineering background, and comprehensively uses geological survey, laboratory tests, theoretical analysis and other methods to verify the characteristics of slope geological structure and physical mechanical properties of soil, at the same time, uses simplified Bishop method to analyze the change law of slope stability under the change of weak layer dip angle, and finally clarifies the influence of weak layer on slope slip mode and stability. The results show that: the initial dip angle of the weak layer is 6°, the corresponding stability factor is 1.553 and the initial landslide mode is the combined failure of shear arc and weak layer. As the dip angle of the weak layer increases, the slope stability coefficient decreases. When the dip angle of the weak layer increases to 56°, the slope slip mode is transformed into the translational failure formed by the weak layer, and the stability factor is reduced to 1.055 at this time.

Abstract
Retention pond have been used widely to manage stormwater runoff to avoid flooding and downstream erosion and even improve water quality. It is an artificial pond that have vegetation around the perimeter and a permanent pool of water. This paper presents the study on water flow behaviours in UNITEN’s retention pond by using ANSYS Fluent. Findings shows that the velocity of water in wet condition is higher than the dry condition because of an additional inlet in wet condition to imitate the heavy rainfall phenomenon. It is also found that the water pressure in wet condition is higher compare to dry condition. Therefore, the conditions that have a higher movement of water can be determined through this simulation. Based on the findings, it can be concluded that the wet condition have a high movement of water behaviour compare to dry condition.
