Abstract: Memory page management is described. A to-be-swapped-out first memory page is determined from a secure memory area of a memory. A second memory page is determined from the memory, where the second memory page is located outside the secure memory area. Based on a physical address of the second memory page by using a memory encryption engine (MEE) of a processor, target data stored on the to-be-swapped-out first memory page is encrypted to obtain a target ciphertext. The target ciphertext is written on the second memory page. The to-be-swapped-out first memory page is released and the second memory page is locked, so that the target data is allowed to swap only from the second memory page into the secure memory area.

Abstract: Disclosed are metallocene compounds, catalyst compositions and methods for making catalyst compositions, and processes for polymerizing olefins. In an aspect, a series of cyclopentadienyl tert-butyl fluorenyl metallocenes featuring various alkylsulfide groups on a carbon bridge linking the cyclopentadienyl tert-butyl fluorenyl ligands were prepared and evaluated as ethylene polymerization catalysts in the presence of metallocene activators, such as solid super acids (SSA). The metallocenes containing these tethered alkylsulfide substituents provide catalysts which exhibited excellent ethylene polymerization activities comparable to the analogous metallocenes containing tethered olefins and polyethylenes with reduced long chain branching (LCB) relative to metallocenes with a saturated hydrocarbyl tether.

Abstract: A method for forming a complex shape three-dimensional ceramic article by printing a first layer of a first material having a first fraction of first ceramic particles and a first fraction of a first polymeric ceramic precursor. A second layer is printed such that it is at least partially disposed on the first layer of a second material having a second fraction of second ceramic particles and a second fraction of a second polymeric ceramic precursor. A composite of the first layer and the second layer is heated at a temperature sufficient to decompose the first and second polymeric ceramic precursors and sinter the article. During the sintering process, the first and second layers with different fractions of ceramic particles undergo different degrees of shrinkage, resulting in a tuneable mismatch of the bilayer structure and accurately achieving a targeted geometry.
