Influence of Ion Streaming Instabilities on Transport Near Plasma Boundaries [PDF]
, 2015 Plasma boundary layers are susceptible to electrostatic instabilities driven by ion flows in presheaths and, when present, these instabilities can influence transport. In plasmas with a single species of positive ion, ion-acoustic instabilities are expected under conditions of low pressure and large electron-to-ion temperature ratio ($T_e/T_i \gg 1 ...

Fast transport of mixed-species ion chains within a Paul trap [PDF]
Phys. Rev. A 90, 053408 (2014), 2014 We investigate the dynamics of mixed-species ion crystals during transport between spatially distinct locations in a linear Paul trap in the diabatic regime. In a general mixed-species crystal, all degrees of freedom along the direction of transport are excited by an accelerating well, so unlike the case of same-species ions, where only the center-of ...

Feedback-Optimized Operations with Linear Ion Crystals
, 2009 We report on transport operations with linear crystals of 40Ca+ ions by applying complex electric time-dependent potentials. For their control we use the information obtained from the ions' fluorescence.

Surfaceome: a new era in the discovery of immune evasion mechanisms of circulating tumor cells
Molecular Oncology, EarlyView.In the era of immunotherapies, many patients either do not respond or eventually develop resistance. We propose to pave the way for proteomic analysis of surface‐expressed proteins called surfaceome, of circulating tumor cells. This approach seeks to identify immune evasion mechanisms and discover potential therapeutic targets. Circulating tumor cells (

High-Fidelity Preservation of Quantum Information During Trapped-Ion Transport [PDF]
Phys. Rev. Lett. 120, 010501 (2018), 2017 A promising scheme for building scalable quantum simulators and computers is the synthesis of a scalable system using interconnected subsystems. A prerequisite for this approach is the ability to faithfully transfer quantum information between subsystems.

Ion Transport in Sperm Signaling
Developmental Biology, 2001 Ion channels and transporters, key elements in sperm-egg signaling and environmental sensing, are essential for fertilization. External cues and components from the outer envelopes of the egg influence sperm ion permeability and behavior. Combining in vivo measurements of membrane potential, intracellular ions, and second messengers with new molecular ...

Salinity tolerance in plants: attempts to manipulate ion transport [PDF]
arXiv, 2014 Ion transport is the major determining factor of salinity tolerance in plants. A simple scheme of a plant cell with ion fluxes provides basic understanding of ion transport and the corresponding changes of ion concentrations under salinity. The review describes in detail basic principles of ion transport for a plant cell, introduces set of transporters
