In this study, an AMI model was established in six Bama miniature pigs by ligation of the mesenteric vessels. Terahertz (THz) transmission spectroscopy (6000–30 cm−1) was performed at 0, 30, 60, 120, 240, and 300 min after ligation. Pathological section was used as the gold standard to evaluate the changes of mesentery before and after ischemia by gross observation, endoscopic observation, pathological section, and THz spectrum. The THz spectra were analyzed to evaluate the changes before and after mesenteric ischemia. THz transmission spectroscopy was performed with acute intestinal ischemia tissue, but no new characteristic peak was found in the resulting spectra. However, the absorption coefficient curve showed an overall increasing and then decreasing trend. The maximum absorption coefficient was obtained 30 min after ligation. Through characteristic peak height analysis, the most obvious change was observed in the PO2− symmetric stretch (wavenumber 1084 cm−1).","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 8","pages":"2097-2100"},"PeriodicalIF":1.5,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144831772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

It will lead to dielectric outgassing and changes in dielectric properties, reducing the tube stability and amplification performance. To solve this problem, a distributed radiation coupling (DRC) circuit with lossy dielectric stepped sheets is proposed, designed, and thermally analyzed for high-power CW gyro-TWTs. It can suppress the parasitic modes by achieving sufficient radiation coupling losses. The adopted stepped sheet structure can increase the heat dissipated area of the lossy dielectric and make the power loss density distribution more uniform, thus decreasing the dielectric temperature. Multiphysics simulations show that an X-band gyro-TWT based on the DRC circuit can achieve a CW power over 100 kW from 8.8 to 10 GHz with a velocity spread of 3.26%. Compared with the traditional DL circuit, the DRC circuit increases the duty cycle of the tube from 50% to a CW state with a tolerable dielectric temperature.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 8","pages":"1852-1858"},"PeriodicalIF":1.5,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144831756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 momentum-balanced equation describes the species dynamics. A triple Beltrami (TB) state is observed when the steady-state solutions for the magnetic field are solved using Ampère’s law. TB state, which combines three distinct Beltrami states, is the subject of this study. We have used cylindrical geometry to find the profile of the magnetic field. We have observed magnetic field profiles for three categories: the variation of Beltrami parameters (BPs), the variation of day and night time events in the Earth’s mesosphere for noctilucent cloud (NLC) structures, and the mass of dust grain. For these categories, diamagnetic and paramagnetic behavior has been observed in the Earth’s mesosphere Earth. This research contributes to a better understanding mesospheric plasma behavior, offering insights into phenomena such as polar mesospheric summer echoes (PMSE) and NLC structures. The findings also provide crucial implications for future environmental studies and the broader understanding of the Earth’s upper atmosphere.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 8","pages":"2068-2077"},"PeriodicalIF":1.5,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144831767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Here, we propose the use of plasma-activated biogel as a novel anticancer approach that is an alternative to plasma irradiation and plasma-activated solutions. Our data show that He plasma jet irradiation generates a variety of ROS in thermosensitive biogel [(poly-DL-lactide)-(poly-ethylene glycol)-(poly-DL-lactide), PLEL]. These plasma-generated ROS retain the oxidative stress of the plasma-activated PLEL biogel (PAB) for at least seven days and are gradually released into the surrounding solutions during the degradation of PAB. In addition, in vitro data show that PAB also has the advantages of excellent cancer cell selectivity and anticancer activity. Our results reveal that plasma-activated biogel is expected to become a novel anticancer CAP-based approach.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 8","pages":"1880-1885"},"PeriodicalIF":1.5,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144831656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
