Abstract: A method, apparatus and computer program product to defend learning models that are vulnerable to adversarial example attack. It is assumed that data (a “dataset”) is available in multiple modalities (e.g., text and images, audio and images in video, etc.). The defense approach herein is premised on the recognition that the correlations between the different modalities for the same entity can be exploited to defend against such attacks, as it is not realistic for an adversary to attack multiple modalities. To this end, according to this technique, adversarial samples are identified and rejected if the features from one (the attacked) modality are determined to be sufficiently far away from those of another un-attacked modality for the same entity. In other words, the approach herein leverages the consistency between multiple modalities in the data to defend against adversarial attacks on one modality.

Abstract: Provided are a battery-level Ni—Co—Mn mixed solution and a preparation method for a battery-level Mn solution, the steps thereof comprising: acid dissolution (S1), alkalization to remove impurities (S2), synchronous precipitation of calcium, magnesium, and lithium (S3), deep ageing to remove impurities (S4), synergistic extraction (S5), and refining extraction (S6). The steps of deep ageing to remove impurities (S4) and synergistic extraction (S5) comprise: performing deep ageing on a filtrate obtained from the step of synchronous precipitation of calcium, magnesium, and lithium (S3), and after performing filtration to remove impurities, obtaining an aged filtrate; using P204 to extract the aged filtrate and obtain a loaded organic phase, and subjecting the loaded organic phase to staged back-extraction to obtain the battery-level Ni—Co—Mn mixed solution and a Mn-containing solution.

Abstract: A collapsible children's pull wagon having four wheels and an upper loop frame pivotably attached to a lower loop frame. There is a hub to which a pull bar and a front axle is coupled to. The front axle is capable of rotating along a vertical axis of the hub in order to change the direction of travel. The pull wagon can easily collapse by releasing a support frame which directly connects the rear end of the upper loop frame to the rear end of the lower loop frame.

Abstract: This disclosure relates to blockchain-based leasing. In some aspects, a leasing party node device of a blockchain network comprising a plurality of connected blockchain nodes acquires leasable state data of a target lease object based on a unique identifier that uniquely identifies the target lease object. The leasable state data is stored in a distributed database on the blockchain network and the leasable state data specifies a leasable state of the target lease object. Lease information of the target lease object is generated in response to acquiring the leasable state data. A first update transaction is transmitted to the blockchain network to update the leasable state of the target lease object. The first update transaction includes at least a portion of the lease information.
