Proxy Re-Encryption (PRE) allows a ciphertext encrypted under Alice’s public key to be transformed to an encryption under Bob’s public key without revealing either the plaintext or the decryption keys. PRE schemes have clear applications to cryptographic access control by allowing outsourced data to be selectively shared to users via re-encryption to appropriate keys. One concern for this appli...

The day before yesterday, June 20, we tried again. The IMPs and TIPs loaded and seemed to fly quite well, so we left the new systems up. But by yesterday, June 21, afternoon, with crashes happening in TIPs at the rate of about one per hour, we backed off again and put the old systems back up. (One TIP crash per hour in the network means there is about one crash every eight or ten hours debuggin...

Equations are established for the deformation of a viscoelastic porous solid containing a viscous fluid under the most general assumptions of anisotropy. The particular cases of transverse and complete isotropy are discussed. General solutions are also developed for the equations in the isotropic case. As an example the problem of the settlement of a loaded column is treated. The second-order e...

Abstract Introduction Many patients with epistaxis are seen in the A&E department. A significant number discharged without need for inpatient admission due to minor bleeds. given limited information on management of further bleeds and even fewer advised prevention Aim To evaluate advice who from A+E, instigate an improvement examine subsequent effect re-attendance rates Method Epistaxis A+E...

T he rapid pace of technological development has brought a wealth of diagnostic and therapeutic options to the care of patients. These new diagnostic and therapeutic tools have dramatically altered medical care but have come with a steep price tag, and it is not clear that the improvement in the quality of care is proportional to the cost of the medical system. In recognition of the fact that t...

The Traditional data warehouse did not contain data as today. Hence, it is difficult to retrieve these data and treat them. Furthermore, its content is not updated, which may lead to bad decisions. Data are typically loaded from conventional operational systems. Given that today’s decisions, in the business world, are becoming more and more in real time. Thus, the system supporting these decisi...
