Abstract: Systems for protein quantitation using a Fabry-Perot interferometer. In one arrangement, a quantitation device includes an infrared source, a sample holder, and a Fabry-Perot interferometer positioned to receive infrared radiation from the source passing through a sample on the sample holder. A band pass optical filter sets the working range of the interferometer, and radiation exiting the interferometer falls on a detector that produces a signal indicating the intensity of the received radiation. A controller causes the interferometer to be tuned to a number of different resonance wavelengths and receives the intensity signals, for determination of an absorbance spectrum.

Abstract: The disclosure provides a highly sensitive assay to detect the presence of a target analyte in a sample.

Abstract: Methods and apparatus to adjust operation of a fluid flow control assembly are disclosed.

Abstract: A target-less point in time image (snapshot) of a storage volume is allowed to be built after activation, by enabling the snapshot data to be modified to create a crash-consistent replica of the source data after the snapshot has been activated. The data of the snapshot remains immutable from a user standpoint, but the snapshot is able to be quickly activated before all of the data of the snapshot has been included in the snapshot, to thus reduce an amount of time IO operations on the source volume are quiesced. A first snapshot of a storage volume is created on a primary storage system and a corresponding second snapshot of the storage volume is activated on a backup storage system before all the data of the first snapshot is received at the backup storage system. Entries of the activated second snapshot are then changed to point to correct back-end allocations.

Abstract: An aspect includes determining a host write rate based on a number of chunks written to a storage volume during a first replication cycle and determining a target rate based on an estimated number of chunks written during a second replication cycle. The target rate is determined by dividing the number of chunks written during the second replication cycle by a recovery point objective (RPO) period. An aspect also includes transmitting chunks written during the second replication cycle at the target rate.

Abstract: A system and method for measuring thicknesses of layers of a multi-layered structure. The method includes generating a terahertz wave pulse, transmitting the terahertz wave pulse to a multi-layered structure having multiple layers of materials, receiving reflected terahertz wave pulses reflected by boundaries between the multiple layers as the terahertz wave pulse penetrates the structure, and processing the reflected terahertz wave pulses to: (i) determine whether the reflected terahertz wave pulses have a pulse width overlap; (ii) in response to determining that a pulse width overlap exists, generate modified reflected terahertz wave pulses; measure the time delays associated with each of the modified reflected terahertz pulses and (ii) determine a thickness of each of the multiple layers of materials based upon the time delay and a material refractive index of each of the materials.

Abstract: A first storage system in one illustrative embodiment is configured to participate in a replication process with a second storage system. Each of a plurality of storage nodes of the first storage system comprises a plurality of storage devices and a set of processing modules configured to communicate with corresponding sets of processing modules on other ones of the storage nodes. In conjunction with the replication process, a first one of the processing modules is configured to generate a request message for transmission to a second one of the processing modules requesting that the second processing module transfer designated replication data to the second storage system. The request message comprises a unique message identifier that the second processing module incorporates into a subsequent response message transmitted back to the first processing module to indicate a result of the requested transfer of the designated replication data to the second storage system.
