Beyond-Mean-Field with an Effective Hamiltonian Mapped from an Energy Density Functional
Authors: Ljungberg J. , Boström J. , Carlsson B. G. , Idini A. , Rotureau J. 
Published: September 2023

Abstract
A method for beyond-mean-field calculations based on an energy density functional is described. The main idea is to map the energy surface for the nuclear quadrupole deformation, obtained from an energy density functional at the mean-field level, into an effective Hamiltonian expressed as a many-body operator. The advantage of this procedure is that one avoids the problems with density dependence which can arise in beyond-mean-field methods. The effective Hamiltonian is then used in a straightforward way in the generator-coordinate-method with the inclusion of projections onto good particle numbers and angular momentum. In the end, both spectra and wave functions are obtained. As an example of the method, calculations for the nucleus 62Zn is performed with three different parametrizations of the Skyrme functional. The results are compared with experiment.

Abstract
Determining the cross sections of neutron-induced reactions on short-lived nuclei is imperative to rate calculations in stellar nucleosynthesis and applications of nuclear physics. It is also an immense experimental challenge due to the radioactivity of the targets involved. Our goal is to circumvent this obstacle by using surrogate reactions in inverse kinematics at the heavy-ion storage rings of GSI/FAIR. We present here preliminary results from the first proof of principle experiment, where a beam of 208Pb impinged on a H2 gas jet target in the Experimental Storage Ring (ESR).

Abstract
An experiment focused on studies of relativistic effects in the proton-deuteron breakup reaction has been performed at Cyclotron Center Bronowice in Kraków, Poland with the use of the Kratta detectors. Thirty Kratta modules have been arranged in a planar symmetric around beam axis configuration at few selected polar angles at which significant relativistic effects have been predicted. In front of each Kratta module 4 thin plastic scintillators were installed acting as a fast timing detectors to improve a trigger system. Determination of acceptance and efficiency of the detectors is discussed.
The 13C(α,n)16O cross section measurement at low energies at LUNA
Authors: Ciani G.F. ,   LUNA collaboration
Published: September 2023

Abstract
One of the main neutron sources for the astrophysical s-process is the 13C(α,n)16O. This reaction takes place in thermally pulsing asymptotic giant branch (TP-AGB) stars in a stellar environmental with temperature of about 90 MK. To model the nucleosynthesis process connected with the reaction, it is important the cross section reaction evaluation inside the so called Gamow peak, in the energy window 150-240 keV. In this work the results of the first 13C(α,n)16O direct measurement performed by the LUNA collaboration in the underground laboratory of LNGS are presented.
The measurement covers the energy range 230-300 keV, being the first direct measurement to reach the s-process Gamow window. Lower uncertainties with respect to previous measurements in literature are provided and this allows to reduce overall uncertainties on reaction rates calculation. Selected stellar models have been computed to estimate the impact of our revised reaction rate. Using the lower reaction rate at -2σ, for stars of nearly solar composition, we find sizeable variations for some isotopes, whose production is influenced by the activation of close-by branching points that are sensitive to the neutron density, in particular 60Fe, 205Pb and and 152Gd.

Abstract

13C(p,γ)14N is a key reaction in different stellar environments for which both accurate and precise measurements of its cross section are required to constraint stellar models. This is currently ongoing at the Laboratory for Underground Nuclear Astrophysics where in addition to the low-background environment, the use of different detection systems (HPGe and BGO detectors) and analysis techniques (Peak Shape Analysis and Sum Peak Method) allowed to perform reaction cross section measurements at the lowest energy ever. Both the setup employed in the measurements and the analysis performed are presented in this paper.

Abstract
The 20Ne(α,p)23Na reaction rate is important in determining the final abundances of various nuclei produced in type Ia supernovae. Previously, the ground state cross section was calculated from time reversal reaction experiments using detailed balance. The reaction rates extracted from these studies do not consider contributions from the population of excited states, and therefore, are only estimates. A resonance scan, populating both the ground and first excited states, was performed for the 20Ne(α,p)23Na reaction, measuring between 2.9 and 5 MeV center of mass energies at the Nuclear Science Lab at the University of Notre Dame. Data analysis is underway and preliminary results show substantial contribution from the excited state reaction.
Carbon burning at stellar energies
Authors: Courtin S. , Heine M. , Monpribat E. , Nippert J. 
Published: September 2023

Abstract
Fusion reactions with light nuclei play an essential role in understanding the energy production, the nucleosynthesis of chemical elements and the evolution of massive stars. The measurement of key fusion reactions at stellar energies is thus of interest, but highly challenging since the associated cross sections are extremely small, of the sub-nanobarn range. Among these reactions, the fusion of carbon nuclei, which drives the stellar carbon burning phase, is deeply connected with essential microscopic features such as the impact of symmetries, the access to quantum states, emerging of resonances or Pauli repulsion effects. These may manifest themselves in exceptional behaviour of the S-factor of this particular system and the precision of extrapolations to deep sub-barrier energies is limited. The present contribution discusses recent experimental results of the nuclear astrophysics community on the measurement of the carbon + carbon fusion reaction down to the astrophysics region. The interplay between nuclear structure, nucleosynthesis and stellar evolution is addressed.

Published: September 2023

Abstract
The concept of theranostics in nuclear medicine is based on the use of a pair of radioisotopes to label radiopharmaceuticals for both diagnosis and therapy and is essential for nuclear medicine developments. The production of novel medical radioisotopes using solid target stations is challenging and new instruments and methods are needed. A research program is ongoing at the 18 MeV Bern medical cyclotron, equipped with a Solid Target Station and a 6.5 m Beam Transfer Line ending in a separate bunker. To irradiate isotope-enriched materials in form of compressed powder pellets, a novel target coin was conceived and realized together with methods to assess the beam energy and the production cross sections. To optimize the irradiation procedure, a novel ultra-compact active irradiation system based on a specific magnetic lens and a two-dimensional beam detector was conceived, constructed and tested. The system allows to control on-line the size and position of the beam and to correct its characteristics by steering and focusing it in order to keep it on target. The first results on the production of several radionuclides (43Sc, 44Sc, 47Sc, 61Cu, 64Cu, 67Cu, 68Ga, 165Er, 165Tm, 167Tm and 155Tb) are presented.

Abstract
This work aims to combine the Polaris-J cadmium zinc telluride semi-conductor detector with a LaBr3:Ce scintillation detector as a hybrid Compton camera that can produce high-quality prompt γ ray images. The LaBr3:Ce detectors (Saint-Gobain Crystals) have outstanding timing resolution (< 350 ps), great energy resolution (< 2.5 % at 1332 keV), and a higher maximum energy range. The goal is to use the strengths of the LaBr3:Ce detectors to offset some of the limitations of the Polaris-J detector.
Overview of the Rare isotope Accelerator complex for ON-line experiments (RAON) project
Authors: Hong Byungsik 
Published: September 2023

Abstract
A new rare-isotope beam (RIB) accelerator complex, RAON, is being constructed in the Institute for Basic Science (IBS) in Korea. RAON is equipped with both isotope separation online (ISOL) and in-flight fragmentation (IF) systems and ultimately combines them to provide more neutron-rich (than any single mode operation) ion beams to the users. However, due to the delay in developing high-energy superconducting cavities and cryomodules, it was decided to proceed with the RAON construction project in two phases. In the first phase, the low-energy accelerator system, ISOL, and all experimental setups will be completed by the end of 2022. In the second phase, the high-energy superconducting system will be completed by 2029 or later. In this contribution, the status of the accelerators, RIB production systems, and experimental instruments for RAON is summarized.

Abstract
KoBRA of RAON has been prepared for various low energy nuclear physics studies such as nuclear structure, reactions, and astrophysics. An α-particle transport test was performed using a standard α-source of 241Am so as to examine the design parameters. The position distribution of the α-particles was measured with a PPAC at the dispersive and achromatic focal planes, and compared with that of a lise
++ Monte Carlo calculation. The results are consistent with each other, confirming a few design parameters. We report on the preliminary results of the α-particle transport test for KoBRA.

Moreover, high level technologies for the construction of particle accelerators and experimental instruments and apparatuses are studied and developed. The laboratory is at present involved in the construction of the SPES facility, which concerns the development of a new research infrastructure devoted to the production of exotic beams for nuclear physics study and new radioisotopes for nuclear medical applications. The heart of SPES is an innovative cyclotron, B70, capable of providing high intensity proton beams (up to 750 μA) in the energy range between 35 and 70 MeV. A description of the present and future challenges at the Legnaro National Laboratory will be given.
A Cooperative Detection of DDoS attacks based on CNN-BiLSTM in SDN
Authors: Zhou Hongwei , Ling Jie 
Published: September 2023

Abstract
In response to the challenges posed by the high overhead and low detection efficiency of traditional SDN, a novel approach has been proposed to detect DDoS attacks. This cooperative method leverages information entropy and deep learning techniques to divide the detection task between the data plane and control plane. An advanced CNN-BiLSTM model with batch normalization and attention mechanism is utilized to identify DDoS attack traffic. The results of experiments demonstrate that this method offers superior accuracy, detection rate, and false alarm rate compared to prior approaches. Moreover, the switch-controller collaborative detection method proposed in this research reduces the occupancy rate of CPU, in contrast to the conventional single point detection method.
C-SwinIR: Dental CT super-resolution reconstruction fused with SwinIR
Authors: Wang Huaizhi , Ding Jiangang , Ye Chao , Yang Ming , Tian Aojia , Li Wei 
Published: September 2023

Abstract
Super-resolution reconstruction (SR) of dental computed tomography (Dental CT) images is a innovative and challenging task. To address the limitations of Dental CT in obtaining high-resolution (HR) images due to equipment constraints and noise interference, we propose a Dental CT SR method called C-SwinIR based on SwinIR. Firstly, the self-calibrated convolutions network (SCNet) is introduced to solve the problem of detail loss in shallow feature graphs and improve the ability to recover details. Subsequently, the cross-shaped windows (CSWin) self-attention transformer structure is used to replace the original transformer structure, which improves the ability of the model to obtain context information. Eventually, the integration of efficient channel attention (ECA-Net) module effectively realizes the local cross-channel interaction, accelerates the model convergence and solves the problem of gradient explosion in training. Experimental results show that our proposed method is superior to the original SwinIR network by achieving a higher peak signal-to-noise ratio (PSNR) and structural similarity index (SSIM) by 0.287 and 0.003 respectively. Additionally, it decreases mean squared error (MSE) by 1.108. By using this method, clinicians can obtain clearer details and textures from Dental CT, which effectively assist in diagnosis.

Published: September 2023

Abstract
Cloud-network integration(CNI) is an inevitable choice to enhance the supply capacity of industrial Internet. In traditional industrial control systems, there are problems such as insufficient depth of perception, insufficient connectivity and insufficient analytical predictability. Firstly, an industrial CNI control architecture is proposed in this paper. Then a software-defined PLC integrated development & runtime environment based on the cloud framework is developed and deployed on a private cloud platform. An efficient 5G private network is created to facilitate wireless omnidirectional connectivity of cloud PLC. The problems of complex industrial field circuits and difficult to unify protocols are solved through 5G intelligent terminal devices. Finally, the cloud control architecture and software platform are successfully applied to the remote centralized control of the tundish preparation system in a steel enterprise’s two steelmaking plants. The results shows that the innovative system architecture meet the requirements for high-performance access, transmission, computing and storage in industrial plants, which achieves the cloud control of entire process industrial automation production.
Energy System Optimization Research Based on PEC-DDPG Algorithm
Authors: Li Jianming , Cheng Guixue 
Published: September 2023

Abstract
Factors such as the stochastic nature of loads in energy systems make it difficult to optimize the operation of integrated energy systems. To address these problems, an energy system economy optimization scheme based on the PEC-DDPG is proposed. Firstly, exponential moving average (EMA) is introduced into deep deterministic policy gradient (DDPG) algorithm, and prioritized experience replay (PER) is added into the experience pool to prioritize the experience to improve the learning efficiency of algorithm, and the overestimation existing in a single Critic network is solved by using multi-Critic structure. Next, the energy system optimization model is constructed, and the appropriate observation states, decision actions and reward functions are selected. Finally, simulations using energy system data of a region show that the optimization of PEC-DDPG is better than the operational optimization of DDPG algorithm.

Abstract
This article proposes a method for determining the scale and location of Distributed Photovoltaic (DPV)under the operational constraints of low-voltage transformer areas. Firstly, a low-voltage transformer areas operation model and a DPV output model were established. Determine the access nodes and rated capacity of the DPV using the indicators of minimizing voltage fluctuations and minimizing line loss rate in the optimized configuration model; Then, the maximum capacity of DPV that can be installed in the transformer area is determined with the goal of maximizing the photovoltaic penetration rate in DPV accessible nodes; Use Marine Predators Algorithm(MPA) to solve nonlinear problems in the model. Finally, simulation analysis was conducted using an actual low-voltage transformer area as an example to demonstrate the effectiveness of the proposed model and method, ensuring the safe and stable operation of the low-voltage transformer area when connected to a high proportion of photovoltaic energy.

Authors: Aziz Fatin Fahim , Hussain Entessar Kareem 
Published: September 2023

Abstract
Groundwater contamination presents an increasing concern for environmental sustainability and human health, especially organic contamination. The effect of leachate percolation on groundwater contamination was investigated at Al-Diwaniyah open dumpsite to assess the groundwater quality of hand-dug observation wells surrounding the dumpsite. Samples of raw leachate and groundwater were collected for laboratory analysis, where they were analyzed using standard methods in order to evaluate any potential seasonal and variations for rainy, and dry seasons. Analytical results of leachate samples indicate that all physiochemical parameters were high revealing that they were highly contaminated with both organic and inorganic materials. High pH value and low BOD5/COD ratio for leachate indicated that dumpsite is old and in the methanogenic stage of anaerobic decomposition. In groundwater, average values of pH, EC, TDS, and major ion concentrations were higher in the dry season as compared to that in the rainy season. In contrast, the variation in TSS, BOD5, and COD showed more in rainy season than in dry season. GW1 and GW2 samples were more impacted by leachate percolation than GW3. The findings further revealed that except for pH, and nitrate all other examined parameters were above the permitted limitations of World Health Organization and Iraqi Quality standards. Relying on pH, EC, and major ions respectively, groundwater adjacent to dumpsite can be described as slightly alkaline, water with health hazards, and Chloride is the dominating ion. Inferred from the preceding, the noticeable influence of climate variation and distance from dumpsite on the extent of groundwater contamination. Continuously monitoring the groundwater resources in the area and constructing engineering landfills subject to the environmental limitations to control leachate infiltration into groundwater is recommended.

Authors: Yahia Fouz Dhafer , Jazie Ali A. 
Published: September 2023

Abstract
Biomass is a plentiful, readily accessible, renewable resource that is expected to take the place of fossil fuels in the production of chemicals and fuel. In this research, the latest and most important research on hydrodeoxygenation was reviewed, and the focus was on water as a source of hydrogen as an alternative to hydrogen. In this procedure, water is crucial., as water contains rare properties that contribute to regulating both reaction rates and mass transfer rates, during the mass transfer process during the hydrogen oxygenation process. The special quality of water helps to control the reaction rates, discrimination, and rates of mass transfer during the biomass HDO process. The focus was on the reaction mechanism of acetic acid, which was selected as the biomass model substance.
Improving the Bus Stops Capacity Depending on Capacity of Bus Lane and Regulated Intersection Capacity
Authors: Asfoor H M A , Averyanov Y I , Golenyaev N S 
Published: September 2023

Abstract
Any stop of buses should be understood along a route, such as the regulated intersections (RI), stopping point (SP), and the road crowding. Thus, the regularities arrival of urban passenger transport (UPT) is impacting the capacity of the of SP, and the number of violations at the stopping point should be known to find a solution to improve the capacity of SP. On the other hand, the process of determining the carrying capacity of a stopping point by urban passenger transport, depending on their type and numbers, remains insufficiently studied yet. In this study, the impact of the type and quantity of UPT on the capacity of the stopping point is illustrated. The conflict at SP that affects the capacity of the stopping point can be solved by controlling the bus’s intensity at a regulated intersection and bus lane. The practical capacities of the various physical elements of the system of UPT servicing that were studied are, a lane capacity (Ql
), a regulated intersection capacity (Qi
), and a stopping point capacity (Qs
). Theoretically substantiating the effects of urban passenger transport types on the SP capacity, formulas were used to determine these practical capacities and compared with the calculated capacity of stopping points according to the HCM2000 model (Qm
) by applying this condition, min {Qi Qi Qs} ≤ Qm
