Abstract: The present application discloses a data query method. The method can be applied to a columnar storage system. The columnar storage system stores target data that is stored in a row storage form, target data that is stored in a columnar storage form, and a row storage index constructed based on the target data that is stored in a row storage form. The columnar storage system can receive a data query request and matches the data query request with the row storage index corresponding to the columnar storage system. If the matching is successful, data matched with the data query request is queried based on the row storage index. Therefore, by use of the scheme, the target data can be stored in the row storage form into the columnar storage system, and the row storage index can be constructed.

The modified tunnel oxide layer is SiOx subjected to plasma surface treatment, and a Si4+ content in the SiOx is greater than or equal to above 18%.

Abstract: The invention relates to a microfluidic poration device having narrow channels slightly smaller than the width of a target cell, wherein the channels are lined with a plurality of nanospikes in a row extending down the middle of the channel, i.e. in a row parallel to the sides of the channel. In one embodiment, one channel may have 2 nanospikes (or 2 nanolancets). Thus, in particular embodiments, the invention provides microfluidic poration devices capable of simultaneously squeezing cells while piercing holes in their membranes for allowing foreign molecules into cells. The holes in porated cells spontaneously close after exiting the channels, thus entrapping the foreign molecules inside of the target cells. This porated cell population has approximately a 95% viability with greater than 50% containing at least one foreign molecule.

Abstract: Mass flow controller (MFC) devices capable of self-verification and methods of providing for self-verifying mass flow control are provided. An MFC includes a chamber configured to receive a fluid, an upstream valve disposed upstream of the chamber, and a downstream control valve disposed downstream of the chamber. The MFC further includes a pressure drop element disposed downstream of the downstream control valve and first and second pressure sensors. A controller of the MFC is configured to control actuation of the downstream control valve by toggling between flow-based feedback control and pressure-based feedback control. In flow-based feedback control, a flow is monitored based on a rate of decay of pressure in the chamber as detected by the first pressure sensor upon closure of the upstream control valve. In pressure-based feedback control, a pressure upstream of the pressure drop element, as detected by the second pressure sensor, is monitored.
