Abstract Since the last IAEA-FEC in 2021, significant progress on development of long pulse steady state scenario and its related key physics technologies have been achieved, including reproducible 403 s long-pulse steady-state H-mode plasma with pure radio frequency (RF) power heating. A thousand-second time scale (∼1056 s) fully non-inductive high injected energy up to 1.73 GJ has also achieved. The EAST operational regime β P significantly extended ( H 98y2 > 1.3, ∼ 4.0, N 2.4 n e / GW...

Abstract During the discharge process, thermal events are common and destructive in Tokamak 
experiments. High energy particles plasma can collide with device components such as limiters 
and diverters, which lead to overheating, material cracking, even damage structure of 
the device. Therefore, we need efficient detection methods monitor real-time. 
To address challenge identifying internal first wall

Pyroptosis is a form of programmed cell death, playing significant role in cancer. Glioblastoma multiforme (GBM) the most common malignant brain tumor. The poor prognosis GBM due to temozolomide (TMZ) resistance has been widely discussed. Such being case, correlation between TMZ and pyroptosis seldom investigated. On this basis, paper aims explore potential prognostic value genes related as well their relationship immune microenvironment GBM. A total 103 patients from TCGA were assigned...
The ab initio/classical free energy perturbation (ABC-FEP) method combines the calculated from a classical simulation of an approximate model with perturbing interactions to initio interaction energies.
