The effective volume of a patient's stomach cavity can be reduced by implanting at least two magnetic devices in the stomach at different locations on the stomach wall. The magnets cooperate with one another magnetically to change the effective volume of the stomach. For example, the magnets may magnetically attract one another to pull in portions of opposite side walls of the stomach. The magnetic devices may be implanted non-surgically (e.g., via one or more catheters introduced into the stomach cavity via the patient's mouth and esophagus). The magnets may be removable to reverse the treatment. Removal may be non-surgical.

A pipettor uses no pistons in order to provide highly automated, precise and accurate pipetting operations. Additionally, a self-aligning pipette tip enables better engagement of such pipette tips by the pipettor. The pipette tips may be automatically engaged and locked into place by the pipettor and may be automatically disengaged to enable highly-automated pipetting processes for industrial and laboratory purposes. Open proximal ends of the pipette tips are engaged by a pipette block, which then forms a temporary seal with the individual pipette tips. Displacement of the pipette block with respect to the pipette tips increased or decreases the effective volume of the pipette tip allowing it to aspirate or expel fluids in a precise, accurate, and predictable way.

The present invention provides a method to detect buying or selling activities of large market players of a given equity, compared to the activity of smaller players. For a set of consecutive trading sessions, the method analyses only trading data (open / high / low / close / volume) aggregated into regular intervals such as one-minute, two-minutes or five-minute trading data. The method considers only time intervals corresponding to price inflections, i.e. for which the closing price was different from the previous time interval. The method further analyses the volume of said time intervals and calculates the effective volume that was responsible for a price inflection. The method then separates the effective trading volumes related to the said time interval into large and small size volumes and plots the evolution of the said volume sizes on a graph. Analysis of trend divergence between large and small size volume flow trends allows detection of the said buying and selling activity by large or small market players.
