Abstract: Disclosed are a video presentation method, device, system and storage medium, which can present video and video comment content at the same time. The method of the present invention comprises: sending a comment presentation request message to a server, the comment presentation request message comprising a first video identifier and a first video play time stamp, so that the server screens comment content directing to a first video corresponding to the first video identifier and using the first video play time stamp as a time start, and generating a first comment content packet; receiving the first comment content packet sent by the server; presenting the comment content directing to the first video in the first comment content packet at the same time when playing the first video. The solution provided in an embodiment of the present invention is suitable for being adopted during video presentation.

Abstract: An edible structure may comprise a gelatin film and fiber strips. The gelatin film may have a higher density of gelatin in a first layer of the film than in a second layer of the film. The fiber strips may be attached to the first layer, and may have an initial orientation, thickness and density. The structure may be configured to undergo a shape transformation when the apparatus hydrates. During the transformation, the film may transform from a flat film into a curved, 3D film. Which specific shape results from the transformation may depend, at least in part, on the initial orientation, thickness and density of the fiber strips. The film may include flavorings or other additives. In some cases, the transformation may change a texture of the structure. In some cases, the transformation may be caused, at least in part, by a change in temperature.

Abstract: Embodiments of the present invention disclose a method and system for indicating a direction. The method is executed by a mobile terminal, and includes: determining an orientation of a screen of the mobile terminal; determining any direction in four directions east, south, west, and north of a location of the mobile terminal; determining another direction based on the determined direction when the screen of the mobile terminal is determined to be downward, so that directions for every 90° are respectively the east, the north, the west, and the south in a clockwise direction; and displaying all the determined directions on the screen of the mobile terminal. By using the solutions in the embodiments, a user can obtain a correct direction indication even when holding the mobile terminal non-horizontally, so that accuracy of the direction indication of the mobile terminal is improved.

Abstract: Metal-organic framework (MOFs) compositions based on nitrogen donor-based organic bridging ligands, including ligands based on 1,3-diketimine (NacNac), bipyridines and salicylaldimine, were synthesized and then post-synthetically metalated with metal precursors, such as complexes of first row transition metals. Metal complexes of the organic bridging ligands could also be directly incorporated into the MOFs. The MOFs provide a versatile family of recyclable and reusable single-site solid catalysts for catalyzing a variety of asymmetric organic transformations. The solid catalysts can also be integrated into a flow reactor or a supercritical fluid reactor.

Abstract: A tough biocompatible hydrogel having one or more drug delivery components, deformable conductors, and/or rigid electronic components incorporated therein in such a way that robust interfaces are formed between the hydrogel and the various components. The resulting hydrogel device provides a highly deformable hydrogel composite in which the reliability and functionality of the incorporated components are maintained even under states of large deformation, and from which one or more drugs can be delivered in a controlled and sustained manner regardless of the state of deformation.

Abstract: A system and method include a distributed virtual tape library node on a distributed computing system node and using a distributed computing system distributed file system to manage data on multiple nodes of the distributed computing system to form a distributed virtual tape library system. A master virtual tape library on a distributed computing system node, multiple slave virtual tape library on a different distributed computing system node, and a distributed computing system distributed file system to manage data on the master and slave virtual tape libraries form a distributed virtual tape library system.

Abstract: A convex minimization is formulated to robustly recover a subspace from a contaminated data set, partially sampled around it, and propose a fast iterative algorithm to achieve the corresponding minimum. This disclosure establishes exact recovery by this minimizer, quantifies the effect of noise and regularization, and explains how to take advantage of a known intrinsic dimension and establish linear convergence of the iterative algorithm. The minimizer is an M-estimator. The disclosure demonstrates its significance by adapting it to formulate a convex minimization equivalent to the non-convex total least squares (which is solved by PCA). The technique is compared with many other algorithms for robust PCA on synthetic and real data sets and state-of-the-art speed and accuracy is demonstrated.
