The membrane scaffold proteins (MSP) of the present invention assemble with hydrophobic or partially hydrophobic proteins to form soluble nanoscale particles which preserve native structure and function; they are improved over liposomes and detergent micelles, in terms of stability and preservation of biological activity and native conformation. In the presence of phospholipid, MSPs form nanoscopic phospholipid bilayer disks, with the MSP stabilizing the particle at the perimeter of the bilayer domain. The particle bilayer structure allows manipulation of incorporated proteins in solution or on solid supports, including for use with such surface-sensitive techniques as scanning probe microscopy or surface plasmon resonance. The nanoscale particles, which are robust in terms of integrity and maintenance of biological activity of incorporated proteins, facilitate pharmaceutical and biological research, structure / function correlations, structure determinations, bioseparations, and drug discovery.

Membrane proteins are difficult to express in recombinant form, purify, and characterize, at least in part due to their hydrophobic or partially hydrophobic properties. Membrane scaffold proteins (MSP) assemble with target membrane or other hydrophobic or partially hydrophobic proteins or membrane fragments to form soluble nanoscale particles which preserve their native structure and function; they are improved over liposomes and detergent micelles. In the presence of phospholipid, MSPs form nanoscopic phospholipid bilayer disks, with the MSP stabilizing the particle at the perimeter of the bilayer domain. The particle bilayer structure allows manipulation of incorporated proteins in solution or on solid supports, including for use with such surface-sensitive techniques as scanning probe microscopy or surface plasmon resonance.

A method for processing an image including: identifying a first group of keypoints in the image; for each keypoint of the first group, identifying at least one corresponding keypoint local feature related to the each keypoint; for the at least one keypoint local feature, calculating a corresponding local feature relevance probability; calculating a keypoint relevance probability based on the local feature relevance probabilities of the at least one local feature; selecting keypoints, among the keypoints of the first group, having the highest keypoint relevance probabilities to form a second group of keypoints, and exploiting the keypoints of the second group for analyzing the image. The local feature relevance probability calculated for a local feature of a keypoint is obtained by comparing the value assumed by the local feature with a corresponding reference statistical distribution of values of the local feature.

A control valve conditioning method in an electrohydraulic pressure control unit comprising at least one electrically triggered solenoid valve that is controlled in an analog manner. The solenoid valve is operated at a specific operating current according to a functional correlation or characteristic diagram between the valve current and the differential pressure characteristic curve when the pressure is controlled, said functional correlation or characteristic diagram being stored in the pressure control unit. The method comprises the following steps: a) temporarily applying at least one anti-hysteresis pulse to the solenoid valve during which a current is set far below or far above the operating current in the valve; b) applying the anti-hysteresis pulse at the desired operating current before or during controlled operation, and c) applying the anti-hysteresis pulse wherein the duration is limited in such a way that the anti-hysteresis pulse has largely no influence on the brake pressure.
