Abstract: A method of carrying out sub-resonant tapping in an atomic force microscope includes causing a probe that is disposed above a sample to be translated in a direction parallel to a horizontal plane defined by the sample and to oscillate in a vertical direction that is perpendicular to the horizontal plane about an equilibrium line that is separated from the horizontal plane by a vertical offset. As a result, the probe repeatedly taps a surface of the sample. Each tap begins with a first contact of the probe on the surface followed by a progressive increase in force exerted by the sample on the probe until a peak force is attained. The vertical offset is controlled by relying at least in part on a feature other than the peak force as a basis for controlling the vertical offset.

Abstract: A method is directed to continuously, non-invasively, and directly measuring blood pressure, and includes providing a calibrated measurement device having a blood-flow control balloon and a sensor array. The method further includes placing the sensor array in a non-invasive manner over the surface of a patch of skin connected to an artery by adjoining soft tissues and inflating the blood-flow control balloon with a controlled amount of pressure. In response to the inflating of the blood-flow control balloon, changes in the artery geometry and forces are detected, via the sensor array, during a heartbeat cycle. The changes correspond to spatio-temporal signals from the artery or in the adjoining soft tissues. The spatio-temporal signals are measured and processed, via a controller, to determine blood-pressure parameters.

Abstract: Compositions and methods are provided for preventing, ameliorating, or treating a disease caused by a species of bacterial genus Vibrio, for example, cholera caused by V. cholerae, the compositions containing two or more strains of lytic bacteriophage that infect and kill Vibrio cells. The bacteriophage are virulent, which replicate intracellularly and lyse and kill the bacteria. Use of two or more strains in a single treatment, as a result of a rate of mutation of the bacteria to simultaneous resistance to all of the bacteriophage to be so low as to be negligible, reduces appearance of phage-resistant bacteria to statistical negligibility. Normal human microbial flora species were not affected. In alternative embodiments of the method and the composition, antibiotic agents or other treatment agents can be administered with a cocktail of the plurality of bacteriophage strains.
