Traditional encryption schemes, both symmetric and asymmetric, were not designed to respect the algebraic structure of the plaintext and ciphertext spaces. Many schemes, such as ElGamal (resp. e.g. Paillier), are multiplicatively homomorphic (resp. additively homomorphic), and can be used to perform limited types of computations directly on the encrypted data and have them pass through the encr...

Cyclic microfracturing and epitaxial crystal growth have long been recognized in crack-seal veins, but an understanding of a single cycle is still missing. Here we present phase-field model that includes both fracture mechanics crack propagation, on the walls, repeating this multiple times polycrystalline, microporous quartz rock. Our simulations two end members: If vein completely seals, it st...

The development of models of marine ecosystems in the Southern Ocean is becoming increasingly important as a means of understanding and managing impacts such as exploitation and climate change. Collating data from disparate sources, and understanding biases or uncertainties inherent in those data, are important first steps for improving ecosystem models. This review focuses on seals that breed ...

Variation was investigated at exon 2 (including part of the putative peptide-binding region) of the class II major histocompatibility complex (MHC) DQB locus for two congeneric phocid seal species and two congeneric otariid seal species. Polymorphism in one phocid species, the southern elephant seal (Mirounga leonina), was comparable to that seen in human populations, while the other phocid, th...

A new approach is proposed in order t o construct a practical automatic identification system for seal impressions. The 3D (three dimensional) measurement method is investigated to select a suitable measurement system for seal registration. The seals are measured as 3D image by employing the range finder system. The pre-processing is performed to correct the slight slant on the measured seal su...

Background: Increasing concern about adolescent mental health problems has resulted in schools being identified as central sites for their prevention (PsycInfo; ERIC 2000–2012). In this context, SEAL for secondary schools was launched in 2007.Method: The implementation strand of the national evaluation of secondary SEAL comprised longitudinal case studies of nine schools and used multiple metho...

Although the Angio-Seal arterial closure device is widely used for preventing bleeding and facilitating early ambulation after arterial puncture, it is also associated with unique complications, such as stenosis, occlusion, or peripheral embolism. We report the first case of a foot ulcer that developed 70 days after an Angio-Seal application. The collagen sponge component accidently positioned ...

Derek Duggan In vivo microleakage evaluation of two root-filling materials in teeth without a coronal seal (Under the direction of Dr. Martin Trope) Two carrier-based materials were compared to assess their resistance to coronal microleakage in a dog model when no coronal seal was present. Histologic evidence of inflammation and infection were the outcome parameters used. Experimental teeth wer...
