Abstract: A system and method for digitally signing data. A method includes generating, by a first device, at least one first secret share based on a secret key chosen by the first device, wherein the first device is offline with respect to a second device; partially signing data by the first device using the at least one secret share, wherein the data is received from the second device without establishing direct communications between the first device and the second device; and sending the partially signed data from the first device to the second device, wherein the second device generates signed data using the partially signed data, wherein the signed data corresponds to a public key generated based on the at least one first secret share and at least one second secret share generated by the second device.

Abstract: The disclosure is directed to cognitive training exercise adapted to train working memory systems in mammals in an intuitive, engaging, and adaptively challenging way to enhance cognition. Exercises engage users in the task of first seeing a grid with angled “bumpers” placed in various places throughout the grid. After a short initial presentation, the bumpers disappear, and the user must remember the location and orientation of the bumpers and calculate a route that a “pinball” will travel after being released from a designated starting position. In this way, the user is manipulating the remembered grid layout in working memory to solve a physically realistic task.

Abstract: A computing device determines a matrix reasoning assessment (MRA) to assess fluid intelligence of a user operating a client computer/device. The MRA includes a matrix having designs in design spaces, where the designs form one or more patterns. The matrix has one or more design spaces in the matrix that are missing a design. Examples of a design include, without limitation, a number, a letter, a symbol. a shape, a picture, an image, a photograph, an icon, an animation, a video, audio, or any other symbol, character, or representation that can be used in a pattern. In one embodiment, the computing device transmits the matrix to the client device. The user responds with a design for the “empty” design space (i.e., the design space previously missing a design) and the computing device receives this design selection.

Abstract: A sidewall construction arrangement for a trailer includes a plurality of upstanding sidewall panels. Each of a plurality of vertically oriented posts is disposed between and engages a respective substantially coplanar pair of the panels. Each post has an exterior surface that is entirely continuous in a vertical cross-sectional view throughout a portion of the post that extends beyond the panels in a lateral direction.

Abstract: Methods and kits for distinguishing between heparanase expressing and heparanase non-expressing hematopoietic cells, particularly useful in distinguishing between different types of differentiated and/or undifferentiated lymphomas and leukemias. The methods and kits are designed to detect heparanase expression, or absence thereof, at the gene, protein and/or protein activity levels.
