An experiment for p(14C,14C* → 10Be+ α)p inelastic excitation and decay was performed in inverse kinematics at a beam energy of 25.3 MeV/u. A series 14C excited states, including new one 18.3(1) MeV, were observed which to various states the final nucleus 10Be. specially designed telescope system, installed around zero degrees, played an essential role detecting resonant near α-separation threshold. state 14.1(1) MeV is clearly identified, being consistent with predicted band-head molecular...
A system for electromagnetic measurements was designed and installed on the Keda Torus eXperiment (KTX) reversed field pinch device last year. Although unique double-C structure of KTX, which allows machine to be opened easily without disassembling poloidal windings, makes convenient replacement modification internal inductive coils possible, it can present difficulties in design flux magnetic probes at two vertical gaps. Moreover, KTX has a composite shell consisting 6 mm stainless steel...
The feedback control of resistive wall modes (RWMs) in Keda Torus eXperiment (KTX) (Liu et al., Plasma Phys. Controlled Fusion 56, 094009 (2014)) is investigated by simulation. A linear model built to describe the growth unstable absence and resulting mode suppression due feedback, given typical reversed field pinch plasma equilibrium. layout KTX with two shell structures (the vacuum vessel stabilizing shell) taken into account. performance explored both scheme “clean control” (Zanca Nucl....

The Magnetized Plasma Fusion Reactor concept is proposed as a magneto-inertial fusion approach based on the target plasma created through collision merging of two oppositely translating field reversed configuration plasmas, which then compressed by imploding liner driven pulsed-power driver. creation process described two-dimensional magnetohydrodynamics model, resulting in typical parameters. implosion and reaction are modeled simple zero-dimensional taking into account alpha particle...
China has experienced an unprecedented rate of urbanization in recent decades. As a city with strong political and economic influences the southwest China, Chongqing is typical example rapidurban development this period time. To study land cover changes urban expansion Chongqing, Landsat images from 1999 to 2018 were selected, processed, quantitatively analysed The results showed that built-up area had increased tremendously during these years, yet vegetation still accounted for vast...
Sentiment analysis is an essential part of the natural language processing domain. Currently, sentiment mainly applied to scenarios such as user tweets, film comments, and opinion analysis. These generally contain sufficient training data. However, for some that lack data, their performance often limited. For this reason, a method based on transfer learning was proposed in study. With self-attention adversarial core framework, could be used assist small-scale specific domain by using data...
The formation of Z-pinch dynamic hohlraums (ZPDHs) can be regarded as a two-phase process consisting the energy thermalization and shock propagation. Once plasma impacts onto convertor, begins with two shocks generated counter-propagating in ends when all has been subjected to shock. Focused on process, simple model is built investigate interaction between matching mass ratio them found by optimizing matter temperature. affected little convertor radius but sensitive initial plasma....
A two-dimensional magnetohydrodynamics model has been used to simulate the target creation process in a magneto-inertial fusion concept named Magnetized Plasma Fusion Reactor (MPFR) [C. Li and X.
