By redefining host-controller responsibilities in this manner, much of the overhead association with FTL functions can be substantially removed from the memory controller, with the host directly specifying physical addresses. This reduces performance unpredictability and overhead, thereby facilitating integration of solid state drives (SSDs) with other forms of storage. The disclosed techniques are especially useful for direct-attached and/or network-attached storage.

Data and error correction information may involve accessing multiple data channels (e.g., 8) and one error detection and correction channel concurrently. This technique requires a total of N+1 row requests for each access, where N is the number of data channels (e.g., 8 data row accesses and 1 error detection and correction row access equals 9 row accesses.) A single (or at least less than N) data channel row may be accessed concurrently with a single error detection and correction row. This reduces the number of row requests to two (2)—one for the data and one for the error detection and correction information. Because, row requests consume power, reducing the number of row requests is more power efficient.

At the same time, since the diameter of the counterbores communicated by the microchannel is slightly greater than the width of the microchannel, the flow rate of the cell sap slows down when the cell sap flows to the counterbores.

The aim of the invention is to be able to constantly open a locking mechanism of an electrically actuated lock of a motor vehicle with sufficiently large force, without having to provide an excessively large electric motor and/or an excessively large gearing transmission ratio for this purpose. In order to solve the problem, a lock for a motor vehicle comprises a locking mechanism (3) and an actuator device for opening the locking mechanism (3). The actuation device comprises a rotatable actuator (1) which can be rotated by a motorised drive (15), in particular by an electric drive. A rotating of the actuator (1) brings about an unlocking, i.e. an opening, of the locking mechanism (3). The locking mechanism (3) can be opened independently of the direction of rotation of the actuator (1). Opening of the locking mechanism (3) is therefore not dependent upon a defined direction of rotation. The force with which the locking mechanism (3) is opened depends on the direction of rotation of the actuator (1). Opening can therefore be achieved with different force depending on the direction of rotation. In this way, in regular operation opening is possible with a lower force compared to a case requiring a greater force for opening. In regular operation, in which a conventional force is used for opening the locking mechanism (3), opening is achieved quickly and with low expenditure of energy. However, it is still possible, if necessary, albeit with delay, to be able to open with greater force for this purpose.

The invention provides methods for detecting specific nucleic acids using a loop-mediated isothermal amplification (LAMP) reaction and providing a digital readout of the results. One method teaches separating target specificity from indicator detection in a two-stage multiple-threshold array (MTA). During the first stage amplicons incorporating both target sequence and an indicator sequence are synthesized. During the second stage of the reaction, the indicator sequence is targeted and amplified to produce visual results that may be digitalized. Another method teaches a competitive MTA, in which a reference sequence is used to compete against target sequence during amplification producing threshold responses, thus enabling digital readout. Using either method, quantitation is achieved without the need for continuous monitoring of the reaction and the end-point readout is amenable to visual inspection. Methods of the invention are especially useful in circumstances where there is lower or intermittent power supply.

Manufacturing lightweight aggregate (LWA) by a sintering technique requires a delicate balance among three conditions: forming sufficient amount of molten liquid phase during sintering; reaching an appropriate viscosity for solid-liquid suspension; and emitting sufficient amount of gas that can be entrapped by the liquid phase to form pores. LWAs were made from low-calcium and high-calcium Waste Coal Combustion Ash (W-CCA) including fly ash and bottom ash. A mass fraction of at least 40% liquid phase for fly ash and 50% for bottom ash is required for a successful entrapment of emitted gaseous phases during sintering. Larger pores were observed in the microstructure of LWA samples made using high-calcium W-CCA in comparison to low-calcium W-CCA. This result was mainly attributed to the high-calcium samples forming liquid phases with lower viscosity values and emitting higher amounts of gaseous phase during sintering than did the low-calcium samples. The gaseous phase was generated by hematite reduction and anhydrite decomposition.
