While traditional methods like stencil-based patterning and microcontact printing lack dynamic control over cell positions, recent innovations such as dielectrophoresis (DEP), acoustic tweezers, magnetic manipulation, and optical tweezers offer enhanced precision. However, synchronizing cell group patterning remains a significant challenge. This study focuses on dynamic cell patterning using optical tweezers, with an emphasis on synchronizing cell positions within a group. We analyze the synchronization error—defined as the differential position error between two cells—and its impact on the overall cell group configuration. A novel feedback position controller is proposed, integrating both position and synchronization errors to ensure asymptotic convergence to zero. Simulation results indicate a significant improvement in precision, with the proposed method achieving a reduction in maximum synchronization error from 1.31 to 0.275 μm (79% decrease) and maximum position error from 2.12 to 1.43 μm (33% decrease) compared to conventional non-synchronized approaches. By enabling precise and scalable control over complex, reconfigurable cell arrangements, this work advances the field of cell patterning and opens new possibilities for applications in drug screening, disease modeling, and organoid development. </p></div>","PeriodicalId":792,"journal":{"name":"The European Physical Journal Plus","volume":"140 5","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144140226","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}

When forms of degradation occur, the manuscript page can in some cases be puzzling for philologists and palaeographers.

Often the research questions cannot be fully addressed by either discipline independently, but only through their combination, the archaeometric philological approach. Among the various manuscript traditions in which the two disciplines can find a common ground of research, the field of early Qur’anic manuscripts represents a challenging area of investigation because of the use of a colour code in their writing system. This paper presents a successful application of a combined approach for the interpretation of a deteriorated and multi-layered Qur’anic codex.

Nonetheless, effective detection of Alzheimer’s disease with accurate biomarkers is highly complicated. This paper introduces a deep learning approach for detection of Alzheimer’s disease. Primarily, input subsequently delineates calculation of filter extents of feature map, subsequent to convolution operation. Images are pre-processed by adopting process of realignment, normalization and smoothing. Subsequently, feature extraction is performed by adopting VGG-16 that is trained by gold rush optimizer algorithm. Finally, Alzheimer’s disease detection is performed by proposed hybrid deep learning model named SpikeGoogle-Deep CNN model that is developed by hybridizing SpikeGoogle and Deep Convolutional Neural Network (Deep CNN) architectures.

To analyze the simplest case, the elastic Boltzmann equation with collisional disruption, where the differential collision cross section of the hard spherical (HS) droplets is symmetrized, is considered as the kinetic toy model. The thermal equilibrium distribution is derived from the kinetic toy model in accordance with the H-theorem. The kinetic toy model shows that the collisional moments corresponding to the diffusion flux and heat flux diverge. Furthermore, the validity of the H-theorem in the kinetic toy model is examined through numerical simulations using the direct simulation Monte Carlo (DSMC) method. To investigate the dissipation process described by the kinetic toy model, the time evolution of correlation functions of fluctuations in the pressure deviator, diffusion flux, and heat flux, and the shock layer around a triangular prism is numerically analyzed. The DSMC results demonstrate that the kinetic toy model reproduces features observed in the Boltzmann equation with a realistic differential collision cross section, including the decay of correlation functions associated with fluctuations in the pressure deviator, diffusion flux, and heat flux. In addition, the Maxwellian droplet model is introduced to support and complement the discussion of the HS droplet case.</p></div>","PeriodicalId":792,"journal":{"name":"The European Physical Journal Plus","volume":"140 5","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144131674","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}

The fundamental qualitative analysis of the model, such as the existence and uniqueness of solutions, as well as their nonnegativity and boundedness, is established. The basic reproduction number <span>(mathcal {R}_0)</span> is derived, and stability of the infection free steady state is proved. Additionally, a comprehensive normalized sensitivity analysis is conducted to assess the model’s robustness across various parameters. Furthermore, to enhance the biological validity of the model, it is fitted to the reported Mpox incidence data from the USA for the period of May 1, 2022 to March 31, 2023. To ensure the reliability, consistency, and accuracy of the model across various states, we provide a comprehensive numerical analysis with graphical representations of statistical indices such as error distribution assessments, regression analysis, and detailed curve fitting for each solution. The regression value <span>(R = 1)</span> across all dataset indicates a perfect correlation between the model predictions and target values. This study contributes to the mathematical modeling of infectious diseases and provides valuable insights for future advancements in the field.
