ARM TrustZone, a security extension that provides a secure world, a trusted execution environment (TEE), to run security-sensitive code, has been widely adopted in mobile platforms. With the increasing momentum of ARM64 being adopted in server markets like cloud, it is likely to see TrustZone being adopted as a key pillar for cloud security. Unfortunately, TrustZone is not designed to be virtua...

Power Architecture R © processors are popular and widespread on embedded systems, and such platforms are increasingly being used to run virtual machines [11, 22]. While the Power Architecture meets the Popek-and-Goldberg virtualization requirements for traditional trap-and-emulate style virtualization, the performance overhead of virtualization remains high. For example, workloads exhibiting a ...

Kinetic analysis of the host guest complexation of a large, open molecular basket and a highly complementary adamantoid guest reveals that for these types of systems a dissociative mechanism is in operation. Hence, the resident adamantyl guest must completely vacate the cavity before another guest molecule can move in to replace it. As a result of the rigid nature of the host, the energy barrie...

Luminescence of porous coordination polymers (PCPs) or metal-organic frameworks (MOFs) is sensitive to the type and concentration of chemical species in the surrounding environment, because these materials combine the advantages of the highly regular porous structures and various luminescence mechanisms, as well as diversified host-guest interactions. In the past few years, luminescent MOFs hav...

On modern processors, hardware-assisted virtualization outperforms binary translation for most workloads. But hardware virtualization has a potential problem: virtualization exits are expensive. While hardware virtualization executes guest instructions at native speed, guest/VMM transitions can sap performance. Hardware designers attacked this problem both by reducing guest/VMM transition costs...

The self-assembly of 2,4,6-tris(pyridin-4-yl)-1,3,5-triazine (tpt) triangular panels with p-cymene-ruthenium building blocks and 5,8-dioxido-1,4-naphthoquinonato (donq) bridges, in the presence of pyrenyl-containing dendrimers of different generations (P(0), P(1) and P(2)), affords the triangular prismatic host-guest compounds [P(n)⊂Ru(6)(p-cymene)(6)(tpt)(2)(donq)(3)](6+) ([P(n)⊂1](6+)). The h...

Cryptophane-C is composed of two nonequivalent cyclotribenzylene caps, one of which contains methoxy group substituents on the phenyl rings. The two caps are connected by three OCH(2)CH(2)O linkers in an anti arrangement. Host-guest complexes of cryptophane-C with dichloromethane and chloroform in solution were investigated in detail by nuclear magnetic resonance techniques and density function...

The enantiomeric recognition of alpha-chiral primary ammonium ions has been studied with benzene-based tripodal tris(oxazoline) receptors. Contrary to the literature and our expectation, a good level of chiral discrimination is observed with one of the tripodal receptors, which provides a C3-symmetric chiral environment on guest binding. The chiral discrimination has been found to be general in...

Gas hydrates, or more generally clathrate hydrates, are a type of inclusion compound and take the form of nonstoichiometic solid crystalline materials formed from water and small guest molecules. Under sufficient pressure of the guest material and at specific temperatures, 3D hydrate structures are formed by the stacking of polyhedral cages of hydrogenbonded water molecules. Suitably sized gues...
