Ion permeation in potassium ion channels

Ion permeation in potassium ion channels

The study of ion channels dates back to the 1950s and the groundbreaking electrophysiology work of Hodgin and Huxley, who used giant squid axons to probe how action potentials in neurons were initiated and propagated. More recently, several experiments using different structural biology techniques and approaches have been conducted to try to understand how potassium ions permeate through the selectivity filter of potassium ion channels. Two mechanisms of permeation have been proposed, and each of the two mechanisms is supported by different experiments. The key structural biology experiments conducted so far to try to understand how ion permeation takes place in potassium ion channels are reviewed and discussed. Protein crystallo­graphy has made, and continues to make, key contributions in this field, often through the use of anomalous scattering. Other structural biology techniques used to study the contents of the selectivity filter include solid-state nuclear magnetic resonance and two-dimensional infrared spectroscopy, both of which make clever use of isotopic labeling techniques, while molecular-dynamics simulations of ion flow through the selectivity filter have been enabled by the growing number of potassium ion channel structures deposited in the Protein Data Bank.

Method for virtual channel management, method for retrieving digital contents, and network-based multimedia reproduction system with virtual channels

A method for virtual channel management is provided. The method includes the following steps. In response to a command, a control unit of a network-based multimedia reproduction system determines whether the command is associated with virtual channel switching. When the command is associated with virtual channel switching, the control unit checks whether a channel value corresponding to the command exists in an application virtual channel table. When the channel value exists in the application virtual channel table, the control unit determines an application corresponding to the channel number from the application virtual channel table, and executes the application. According to a first operation parameter set corresponding to the application, the control unit sets the executed application to retrieve digital contents through a network unit of the network-based multimedia reproduction system.

Characteristic response extraction for non-linear transmit channels

Techniques for extracting the characteristic response of a non-linear channel are presented. In various implementations of the invention, a channel's characteristic response may be determined by identifying a first input sequence, determining the ones compliment of the first input sequence and then determining the response of the channel to these two input sequences. Subsequently, two input matrices and two response matrices may be generated based upon the two input sequences and their corresponding responses. Given these four matrices, a symmetrical response component may be determined by iteratively solving a system of equations formed from the columns of each matrix. Subsequently, given the symmetric component and these four matrices, an asymmetrical response component may be determined by again iteratively solving the system of equations for the columns of each matrix.

Controllable air ducts for feeding of additional combustion air into the area of flue gas channels of coke oven chambers

A device for feeding and controlling secondary air from secondary air ducts into flue gas channels of horizontal coke oven chambers is shown. The flue gas channels are located underneath the coke oven chamber floor on which coal carbonization is realized. The flue gas channels serve for combustion of partly burnt coking gases from the coke oven chamber. The partly burnt gases are burnt with secondary air, thus heating the coke cake also from below to ensure even coal carbonization. Secondary air comes from the secondary air ducts connected to atmospheric air and to the flue gas channels. Controlling elements are mounted in the connecting channels between the flue gas channels and secondary air ducts which can precisely control the air flow into the flue gas channels. Thereby, it is possible to achieve a much more regular heating and heat distribution in coke oven chambers. The actual controlling devices in the connecting channels can be formed by turnable pipe sections, wall bricks, or metal flaps. It is particularly advantageous to utilize a hump-like facility (tabouret) which sits in the secondary air ducts and which is comprised of a tabouret plate with a central opening that is slid under the corresponding embranchment to regulate the gas stream. The controlling mechanism can be actuated manually, electrically, or pneumatically. Thereby, the controlling device can also be automated.
