Abstract: A data migration method for a storage system after expansion and a storage system are provided. After an ith expansion is performed on the storage system, data migration is performed by using an auxiliary balanced incomplete block design. Because a quantity of tuples including any element in the auxiliary balanced incomplete block design is identical, and each migration unit includes an identical quantity of parity chunks, a data migration amount after the expansion is minimized. In this way, time required for data migration after the expansion is significantly reduced, and a delay in a response to a user request that is caused because a data migration operation needs to be performed after the expansion is also reduced.

Abstract: A sequence signal generator and a sequence signal generation method are provided. In the sequence signal generation method, a waveform output instruction sent by a host computer is received to acquire waveform data. The waveform data includes original square wave sequence data and target square wave sequence data, and the target square wave sequence data includes a preliminary delay parameter and a secondary delay parameter. An original square wave sequence signal is acquired according to the original square wave sequence data. According to the preliminary delay parameter, preliminary delay processing is performed on the original square wave sequence signal to acquire an intermediate square wave sequence signal, and according to the secondary delay parameter, secondary delay processing is performed on the intermediate square wave sequence signal to acquire a target square wave sequence signal.

Abstract: The synthesis and characterization of a platinum (II) terpyridine system tethered with a latent organic dye of rhodamine derivative as colorimetric and fluorescent sensory moiety has been reported to show selective Hg2+ ion sensing behavior. The interplay of aggregation/de-aggregation behavior of the alkynylplatinum(II) terpyridine complex and the ring-opening process of rhodamine derivative has been investigated. The spectral change of aggregation NIR emission at 800 nm and rhodamine fluorescence at 585 nm provides a possible ratiometric luminescence measurement. Morphological studies from TEM and SEM images showing nanospherical structures confirmed the aggregation in the absence of Hg2+ ion.

Abstract: Provided is a visible light communication transceiver. A drive amplification module performs digital-to-analog conversion and amplification on a digital modulation signal to obtain a first electrical signal, and transmits the signal to a Bias Tee-like circuit. The Bias Tee-like circuit transmits the first electrical signal to a LED light source. The LED light source performs electrical-to-optical conversion on the first electrical signal to generate a first optical signal and transmits the first optical signal, and performs optical-to-electrical conversion on a received second optical signal to obtain a second electrical signal. The Bias Tee-like circuit obtains the second electrical signal from the LED light source, and transmits the second electrical signal to an adaptive amplification and equalization module. The adaptive equalization module adjusts a gain of the second electrical signal based on an optical power of the first optical signal.

Abstract: A conjugate containing a fluorescent chromophore, which has any structure selected from C1 to C3. The conjugate containing the fluorescent chromophore provided by the described embodiments includes one fluorescent chromophore and two highly reactive groups R1 and R2 linked to the fluorescent chromophore by a covalent bond. The fluorescent chromophore in the conjugate initially has no or only weak fluorescence emission capability, and only after the two highly reactive groups react together with the corresponding molecule, the fluorescent chromophore has strong fluorescence emission. Therefore, the efficiency of conjugation of drug molecules to targeting molecules can be monitored in situ by the infrared fluorescence emission intensity and applied to the target-mediated drug delivery.
