In this letter, we present a novel kinetic model that incorporates both vibrational N_{2} kinetics and N_{2}O_{5} dissociation reactions in plasma chemistry. This model describes the experimental results of discharge mode transition self-consistently, which has not been achieved before. It is found that both power- and temperature-triggered discharge mode transitions are directly induced by the enhanced recombination of NO and NO_{2} to quench O and O_{3}. Two distinct pathways for NO and NO_{2} production are identified: high discharge powers sustaining the excitation of N_{2} to high vibrational levels and elevated gas temperature accelerating N_{2}O_{5} dissociation. Essentially, both species are indispensable for enabling discharge mode transition, as their absence leads to significant deviations in transition dynamics. These results explain the origin and kinetics of discharge mode transition and contribute to further advancing plasma applications.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"111 6-2","pages":"065205"},"PeriodicalIF":2.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144761990","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 fKP equation is derived from a three-fluid-Poisson model of the dusty plasma using the reductive perturbation technique and numerically solved for parameters close to the experimental investigations of cylindrical precursor solitons. The fKP model solutions show excellent agreement with the experimental results in reproducing the prominent geometric features of the two-dimensional solitons and closely matching the quantitative values of their velocities, amplitudes, and temporal evolutions. Our findings suggest that the fKP equation can serve as a very realistic model to investigate the dynamics of precursor solitons and can be usefully employed in practical applications such as space debris detection and tracking techniques that are based on observing/predicting nonlinear plasma excitations induced by the debris in the ionosphere.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"111 6-2","pages":"065201"},"PeriodicalIF":2.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144761994","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}

However, the generation of intense LG beams remains challenging because of the limited damage threshold of intensity for optical elements used for the conversion from normal Gaussian beams to LG beams. Here, we propose a plasma-based scheme to amplify a LG pulse through energy transfer from copropagating multiple Gaussian pulses as pumps. It is found that efficient energy transfer can be realized by properly choosing the relative phase difference between the LG pulse and the Gaussian pulses, where the intensity of the LG pulse can be enhanced by nearly two orders of magnitude. This scheme works for either weakly or highly relativistic intense lasers, as well as for LG pulses with different topological charges. Furthermore, the properties of the amplified LG pulse can be manipulated by controlling the Gaussian pulses, such as the pump laser beam number, laser intensity, and propagation direction. Our studies provide a way of using plasma optics to amplify LG lasers to relativistic high intensity and manipulate their spatial structure for applications.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"111 6-2","pages":"065211"},"PeriodicalIF":2.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144761884","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}

Dipteran insects can beat their wings hundreds of times per second, with each wing reversing its pitch direction twice per wingbeat. However, the neural signals hardly match up to such high frequencies, making it interesting to consider how insects regulate wing pitch in a timely manner. In this study, we investigate this problem through observations and simulations involving droneflies. Wing kinematics modulation is induced by imposing unilateral wing damage and recorded by high-speed videography. In tethered flight, the wing pitches passively without mechanical feedback, creating an imbalanced roll moment, which can be overcome by active actuation in free hover. Simulations, based on the torsional spring passive pitching model, suggest that insects modulate wing pitch through the coupling of aerodynamic, inertial, and wing hinge elastic forces. The model predicts the trend of wing pitch subjected to wing area loss as the observation and achieves a similar control effect of balancing roll moment with a slight adjustment to spring parameters. Based on these results, we show that insects combine passive and active mechanisms for wing pitch modulation.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"111 6-1","pages":"064414"},"PeriodicalIF":2.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144761890","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}
