Edge turbulence spreading and blob transport broaden the heat flux width approaching the density limit [PDF]

Nuclear Fusion
This paper investigates how edge turbulence spreading and blob transport broaden the heat flux width in Ohmic-plasma approaching the operational density limit of the J-TEXT tokamak. At the plasma edge, ${{\boldsymbol{E}}_{\mathbf{r}}} \times {\mathbf{B}}$

Experimental evidence for increased particle fluxes due to a change in transport at the separatrix near density limits on Alcator C-Mod [PDF]

Nuclear Fusion
Experimental inferences of cross-field particle flux at the separatrix, $\Gamma_{\perp}^\mathrm{sep}$ , show rapid growth near H-mode and L-mode density limits at high magnetic field on Alcator C-Mod.

Multimode-enabled silicon photonic delay lines: break the delay-density limit [PDF]

Light: Science & Applications
Integrated optical delay lines have become imperative to meet the growing demand as large aperture antennas and high number of subarrays required for microwave beamforming, high-speed optical communication, and integrated quantum photonics.

Output power-density limit of a thermoradiative diode with an intermediate band [PDF]

Scientific Reports
The application of the thermoradiative effect of photodiodes, in which photons are emitted to a cold reservoir in the far-field, is a promising approach for renewable electricity generation.

Low-Density Neutron Matter and the Unitary Limit

Frontiers in Physics, 2021
We review the properties of neutron matter in the low-density regime. In particular, we revise its ground state energy and the superfluid neutron pairing gap and analyze their evolution from the weak to the strong coupling regime. The calculations of the

Validation of the plasma-wall self-organization model for density limit in ECRH-assisted start-up of Ohmic discharges on J-TEXT

Nuclear Fusion, 2023
A recently developed plasma-wall self-organization model (Escande et al 2022 Nucl. Fusion 62 026001) predicts a significantly enhanced density limit, which may be attainable in tokamaks with ECRH-assisted Ohmic start-up and sufficiently high initial ...

Resolution limit revisited: community detection using generalized modularity density

Journal of Physics: Complexity, 2023
Various attempts have been made in recent years to solve the resolution limit (RL) problem in community detection by considering variants of modularity in the detection algorithms. These objective functions purportedly largely mitigate the RL problem and

Nonequilibrium charge-density-wave order beyond the thermal limit

Nature Communications, 2021
Photo-induced phase transitions triggered by an ultrafast excitation cannot be described within the quasi-equilibrium framework. Here, using time-resolved experimental probes, the authors report a transient charge-density-wave order in TbTe3 and describe

Support and density of the limit $m$-ary search trees distribution [PDF]

Discrete Mathematics & Theoretical Computer Science, 2012
The space requirements of an $m$-ary search tree satisfies a well-known phase transition: when $m\leq 26$, the second order asymptotics is Gaussian. When $m\geq 27$, it is not Gaussian any longer and a limit $W$ of a complex-valued martingale arises.

Anthracycline-induced cardiotoxicity: targeting high-density lipoproteins to limit the damage?

Lipids in Health and Disease, 2022
Doxorubicin (DOX) is an anthracycline antibiotic frequently used against a wide range of cancers, including breast cancer. Although the drug is effective as a treatment against cancer, many patients develop heart failure (HF) months to years following ...
