The primary neutrons are generated from the interaction of 45MeV protons with a tantalum target. The simulations were performed using several Monte Carlo codes (MCNP, PHITS, McStas, VITESS, and KDSource) together with nuclear data from the ENDF/B-VII.1 and JENDL<span>(-)</span>5.0 libraries. The simulated primary neutron yields had deviations from experimental measurements ranging from 0.3 to 16% depending on the code and the nuclear data used. The neutron moderation in the para-hydrogen moderator coupled with a neutron guide was then modeled. The neutron time distribution was measured by a <span>(^3)</span>He detector at the end of the guide. Comparison with experimental data showed good agreement, with relative differences of less than 15%. For the 99.9% para-hydrogen concentration, simulations with JENDL<span>(-)</span>5.0 were in better agreement with the experimental data, while ENDF-B/VII.1 showed better agreement for the 25% para-hydrogen case. The analysis of the results obtained provides insights into the strengths and limitations of each Monte Carlo code and nuclear data library combination. The observed discrepancies were analyzed, and possible sources of error were also identified. The analytical procedure followed in this work will help to improve the accuracy and reliability of neutron cold moderator design.</p></div>","PeriodicalId":792,"journal":{"name":"The European Physical Journal Plus","volume":"140 2","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1140/epjp/s13360-025-06046-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143373317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

NaI(Tl) detectors are preferred for their cost-effectiveness, efficiency, and ease of construction, while HPGe detectors have superior resolution but face challenges in temperature operation and they are expensive. This article investigates the application of machine learning algorithms, specifically K-Nearest Neighbors (KNN) and a Multi-Channel Output Regression based on Support Vector Regression (MCO-SVR), to enhance the performance of NaI(Tl) detectors by transforming its gamma spectrum into HPGe spectrum. The model was trained using datasets generated from a limited radioisotope library and demonstrated excellent performance across a diverse range of measured experimental test data. The evaluation included various scenarios, such as low-count spectra and background effects. The KNN model exhibited optimal performance, achieving an accuracy of 98.69% with a Manhattan distance metric. In contrast, the MCO-SVR model, employing both direct and chained approaches, exhibited varied results with different kernel types, with the polynomial kernel in the direct approach yielding the value 97.45% accuracy. Overall, the results indicate that machine learning algorithms have the potential to improve the performance of NaI(Tl) detectors and expand their applications in various fields of nuclear security.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":792,"journal":{"name":"The European Physical Journal Plus","volume":"140 2","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1140/epjp/s13360-025-06048-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143369995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Event shape-based studies in pp collisions have succeeded to a certain extent in identifying the rare events mimicking such heavy-ion-like behavior. In this study, we incorporate PYTHIA8 and AMPT to study radial flow-like signatures in pp collisions at <span>(sqrt{s} = 13)</span> TeV as a function of transverse spherocity and pseudorapidity. The selection of softer events possibly carrying heavy-ion-like features is performed using the transverse spherocity event shape observable. As the particle production mechanism in midrapidity differs greatly from the forward rapidity, a pseudorapidity dependent study is meaningful. Keeping ALICE 3 upgrades at the LHC in mind, this study aims to demonstrate the transverse spherocity and pseudorapidity dependence of the mean transverse momentum, particle ratios, and kinetic freeze out parameters in pp collisions at <span>(sqrt{s})</span> = 13 TeV using PYTHIA8. We observe that the isotropic events show enhanced radial flow effects in all multiplicity classes, however, the jetty events show signatures of the radial flow-like effects only in high-multiplicity events. For the first time, we show the transverse spherocity and pseudorapidity dependence of partonic modification factor in pp collisions, which clearly shows that by choosing transverse spherocity, one can directly probe the radial flow-like effects in pp collisions at the LHC.</p></div>","PeriodicalId":792,"journal":{"name":"The European Physical Journal Plus","volume":"140 2","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143370011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Located in the “World Wind City” of Guazhou, Suoyang Ancient City experiences maximum wind velocities of 24 m/s, leading to severe sand accumulation and damage to its walls. This study focused on a typical 70-m-long section of the east wall of Suoyang Ancient City, featuring a gap, and utilized unmanned aerial vehicle (UAV)-assisted modeling technology to construct a three-dimensional model of the wall. Computational fluid dynamics (CFD) methods were employed to simulate the movement and accumulation processes of wind-blown sand. The research found that upward airflow at the upper part of the wall enables sand particles to surmount the wall's top, while downward airflow at the lower part accelerates the downward deposition of sand particles at the base of the wall. The wind field on the windward side is evenly distributed, resulting in relatively uniform sand deposition. Conversely, on the leeward side, a reflux zone forms after the airflow passes over the wall, causing sand particles to accumulate in an arc-shaped pattern behind the wall. The simulated results align with actual observations of sand accumulation at the gap in the east wall, providing valuable insights for sand prevention and control efforts at the Suoyang Ancient City.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":792,"journal":{"name":"The European Physical Journal Plus","volume":"140 2","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143370050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, pure geopolymer and carbon nanotubes (CNTs)/geopolymer continuous composite microfibers, with a diameter of ~ 300 µm, were synthesized using a wet spinning method. Sodium alginate (SA) was utilized as a dispersant, and a solution of 5% CaCl<sub>2</sub> in 75% ethanol served as the coagulation bath.

The tensile stress and Young’s modulus of the CNTs/geopolymer fibers reached 35.41 ± 1.09 MPa and 33.22 ± 0.99 MPa, respectively, with a CNTs content of 25 wt.%. In addition, the high MB removal rates (~ 84%) were achieved after 24 h when the initial concentration of MB was 10 mg/L.

Studies identify that variations in free stream velocity, surface mass transfer, wall temperature, buoyancy forces, magnetization, chemical reactions, etc are factors responsible for the non-similar boundary layer problem (N-SBLP). However, the assumptions in this study including dissipative heat, a Darcian medium, non-Newtonian fluid, nonlinear buoyancy, convective heat transfer, chemical reaction rates, and Soret–Dufour effects give rise to the N-SBLP, thus necessitating the use of the non-similar technique.

A mathematical model is developed to investigate the thermal behaviour of copper–alumina/water nanofluid in a vertical microtube. By employing a lubrication approach, analytical solutions are derived for velocity profiles, temperature fields, and heat transfer characteristics. Results show significant enhancements in heat transfer rates due to the combined effects of membrane pumping and magnetic field. By using the MATLAB code, results for velocity profiles, volumetric flow rates, wall shear stress, stream functions, and pressure differences are illustrated. Additionally, heat transfer analysis for hybrid nanofluid (copper–alumina/water) flow is scrutinized, yielding insights into temperature, Nusselt numbers, and isotherms.
