  • Publication number: 20240387157
    Abstract: A method of processing data determined from an image-charge/current signal representative of ions of a given charge state (Q) undergoing oscillatory motion of a respective oscillation frequency (f) within an ion analyser apparatus. A data set comprises a measured signal frequency (f0) common to a plurality of a measured image-charge/current signals and a plurality of estimated ion charge values corresponding to respective amplitudes of each one of the plurality of measured image-charge/current signals. An integer charge value ([Q]) is generated corresponding to a said estimated ion charge value rounded to the nearest integer value. Using the integer charge value ([Qi]) a plurality of different candidate image-charge/current signal frequency values (fCandi) are calculating according to said selected measured signal frequency (f0) and according to a corresponding one of one or more different candidate charge states of ion (e.g., protonation) and/or of ion isotope or isotopologue.

  • Publication number: 20240303104
    Abstract: Techniques for managing proxy virtual machines are disclosed. In some embodiments, a computer system deploys proxy virtual machines on a data center in an intelligent way in order to optimize performance and efficiency for backing up data from and restoring data to the data center, using the topology of the data center to determine how many proxy virtual machines to deploy and on which specific hosts to deploy the proxy virtual machines. Rather than determining the number of proxy virtual machines to deploy based on a maxing out of all of the ports on each proxy virtual machine to handle a planned quantity of backup jobs, the computer system may calculate the number of proxy virtual machines to use based on a rule that ports be left available for un-planned on-demand restore jobs.
