Collisional Penrose process in Kerr–Taub–NUT spacetime

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
Maximum efficiency of collisional Penrose process with spinning and non-spinning particles in Kerr–Taub–NUT spacetime has been studied. We consider three cases in detail: two massive particles collide near the horizon, one of the resulting massive ...

Cryptococcus escapes host immunity: What do we know?

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
Cryptococcus is an invasive fungus that seriously endangers human life and health, with a complex and well-established immune-escaping mechanism that interferes with the function of the host immune system.

Optimal Escape from Sun-Earth and Earth-Moon L2 with Electric Propulsion

open access: yesAerospace, 2022
Optimal low-thrust trajectories for the direct escape from the Earth’s sphere of influence, starting from Sun-Earth or Earth-Moon L2, are analyzed with an indirect optimization method.

Sensing Offshore Aquaculture Infrastructures for Data-Driven Dynamic Stress Analysis

open access: yesFishes
The presence of escaped fish in aquaculture facilities as a result of harsh meteorological conditions (more pressing in the face of climate change) requires a better understanding of this dynamic behaviour through vigilant monitoring and validated ...

Escaping Eritrea:

open access: yes, 2023
In Sinai trafficking Eritreans made up the majority of victims. But what makes them so vulnerable to human trafficking for ransom? The interviews for this chapter found a number of reasons, including the fact that Eritrea is a ‘black hole’ in the digital landscape – which means that Eritreans are uninformed and dependent on smugglers and traffickers ...

Trapped waves generated by an accelerated moving disturbance for the Whitham equation

open access: yesPartial Differential Equations in Applied Mathematics, 2022
In this work, we study numerically the generation of trapped waves excited by the passage of an accelerated moving disturbance along the free surface using the forced Whitham equation as a model.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Kinetics of HIV-Specific CTL Responses Plays a Minimal Role in Determining HIV Escape Dynamics

open access: yesFrontiers in Immunology, 2018
Cytotoxic T lymphocytes (CTLs) have been suggested to play an important role in controlling human immunodeficiency virus (HIV-1 or simply HIV) infection.

Wheat Escapes Low Light Stress by Altering Pollination Types

open access: yesFrontiers in Plant Science, 2022
Although low light stress seriously affects florets fertility and grain number during the reproductive period, crops can be fertilized by heterologous pollen to alleviate the reduction of grain number. However, wheat is strongly autogamous, how to change
