Abstract: In one embodiment, storage drive dependent track removal processing logic performs destage tasks for tracks cached in a cache as a function of whether the storage drive is classified as a fast class or as slow class of storage drives, for example. In one embodiment, a destage task configured for a slow class storage drive, transfers an entry for a track selected for destaging from a main cache list to a wait cache list to await destaging to the slow class drive. A destage task configured for a fast class storage drive allows the cache list entry for the selected track to remain on the main cache list while the selected track is being destaged to the fast class storage drive, thereby bypassing the transfer of the entry to a wait cache list. Other features and aspects may be realized, depending upon the particular application.

Abstract: Systems and methods taught herein enable simultaneous forward and side detection of light originating within a microfluidic channel disposed in a substrate. At least a portion of the microfluidic channel is located in the substrate relative to a first side surface of the substrate to enable simultaneous detection paths with respect to extinction (i.e., 0°) and side detection (i.e., 90°). The location of the microfluidic channel as taught herein enables a maximal half-angle for a ray of light passing from a center of the portion of the microfluidic channel through the first side surface to be in a range from 25 to 90 degrees in some embodiments. By placing at least the portion of the microfluidic channel proximate to the side surface of the substrate, a significantly greater proportion of light emitted or scattered from a particle within the microfluidic channel can be collected and imaged on a detector as compared to conventional particle processing chips.

Abstract: The present disclosure relates to an anti-miRNA delivery system, and more specifically, relates to a technique of using a cancer-targeting anti-miRNA delivery system including porous silicon nanoparticles containing anti-miRNA to which a cancer cell surface protein-binding peptide is conjugated, for use in treating cancer. As a result of intensive studies in order to use and apply anti-miR-21 oligonucleotides to the treatment of ovarian cancer, the present inventors confirmed for the first time that when porous silicon nanoparticles containing an anti-miRNA-21 oligonucleotide to which a specific cancer cell surface protein-binding peptide is conjugated are applied, apoptosis is induced in an ovarian cancer cell line and cell viability is reduced, thus, an anti-miRNA delivery system, which is the aforementioned conjugate, is expected to be usefully used as a platform for treating various cancers, especially for treating ovarian cancer.

Abstract: Techniques are provided for selection of machine learning algorithms based on performance predictions by using hyperparameter predictors. In an embodiment, for each mini-machine learning model (MML model), a respective hyperparameter predictor set that predicts a respective set of hyperparameter settings for a data set is trained. Each MML model represents a respective reference machine learning model (RML model). Data set samples are generated from the data set. Meta-feature sets are generated, each meta-feature set describing a respective data set sample. A respective target set of hyperparameter settings are generated for said each MML model using a hypertuning algorithm. The meta-feature sets and the respective target set of hyperparameter settings are used to train the respective hyperparameter predictor set. Each hyperparameter predictor set is used during training and inference to improve the accuracy of automatically selecting a RML model per data set.
