Lanthanide-Selective Artificial Channels
ACS NanoLanthanides serve as essential elements for modern technology, playing critical roles in batteries, wind turbines, portable electronics, and energy-efficient lighting. Purifying lanthanides from ores and recycling them from end-of-life consumer materials are costly and damaging to the environment due to inefficient separation technologies.

The share of logistics and transportation in the overall cost of a product is increasing. Subsequently, there is a growing pressure in the logistics industry for optimization and cost reduction. In this paper, we consider the issue of transport channel selection, a problem that has been overlooked for a long time. Typical choices for transport channels

Ion-selective conductances of a cell membrane are mediated by electrogenic carriers or channel proteins. In this chapter on Ion-Selective Channels we will discuss in more detail channels that are the dominating ion pathways governing the membrane potential.

Cancer-Related Channel Selection
Health Communication, 1992This study examined the impact of three major classes of factors, triggers, impediments, and demographics on the selection within and across four different channels: doctors, friends/family, organizations, and media. Women 40 years of age and older (N = 395) were asked which channels they have turned to within the last year for cancer-related ...

In the previous chapters, we have considered the case of frequency flat-fading channels. In this chapter, we extend the bounds on the achievable rate derived in Chapter 3 to the case of frequency-selective (wideband) channels. To get to a mathematically tractable discrete-time discrete-frequency system model, we use the approach given in [33] which is ...

On relay selection in frequency selective channels
2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2011We consider relay selection in cooperative relay networks with frequency selective fading, and focus on a system where multiple decode-and-forward relays share a single channel orthogonal to the source. We propose a relay selection scheme and end-to-end transciever architecture which employs a simple decision feedback equalizer, and we show ...

After two downconversions in the receive path, the baseband signal must be detected. As explained earlier in Chapter 2, the baseband signals can be demodulated in either the digital or the analog domain. Accompanied by interferers in both cases, the desired signal must be applied to a channel-select filter.

Phospholamban generates cation selective ion channels
Physical Chemistry Chemical Physics, 2011Phosholamban (PLN) is involved in the contractility of cardiac muscles by regulating the intracellular calcium concentration (Ca(2+)(cyt)) of cardiac myocytes. This occurs via a modulation of the sarco-/endoplasmic CaATPase (SERCA). In spite of high-resolution structures the molecular mode of PLN action is yet not known.

Channel Selection and the Suffix Effect
Quarterly Journal of Experimental Psychology, 1975Subjects were presented with a list of digits to alternate ears for serial recall. The list was followed by a suffix, a redundant acoustic event which did not have to be recalled. The suffix was presented either to one of the ears or binaurally. In all cases the suffix gave rise to a selective impairment of recall of the final items in the list.

Ion selectivity of epithelial Na channels
The Journal of Membrane Biology, 1987Epithelial Na channels are apparently pore-forming membrane proteins which conduct Na much better than any other biologically abundant ion. The conductance to Na can be 100 to 1000 times higher than that to K. The only other ions that can readily get through this channel are protons and Li.
