Age estimation from facial images is typically cast as a nonlinear regression problem. The main challenge of this problem is the facial feature space w.r.t. ages is heterogeneous, due to the large variation in facial appearance across different persons of the same age and the nonstationary property of aging patterns. In this paper, we propose Deep Regression Forests (DRFs), an end-to-end model,...

The bluetongue virus (BTV) core particle contains 2 major polypeptides, P3 and P7, and is surrounded by an outer capsid layer that is composed of the 2 major polypeptides, P2 and P5. Analysis of the immune precipitates from soluble 14C-labelled BTV polypeptides and hyper-immune rabbit and guinea-pig sera indicated that polypeptide P2 precipitates only with homologous BTV sera. This would indica...

Internet security was once based on trust and needs to be updated.

BACKGROUND Symbiotic nitrogen (N)-fixing trees are rare in late-successional temperate forests, even though these forests are often N limited. Two hypotheses could explain this paradox. The 'phylogenetic constraints hypothesis' states that no late-successional tree taxa in temperate forests belong to clades that are predisposed to N fixation. Conversely, the 'selective constraints hypothesis' s...

Component hijacking is a class of vulnerabilities commonly appearing in Android applications. When these vulnerabilities are triggered by attackers, the vulnerable apps can exfiltrate sensitive information and compromise the data integrity on Android devices, on behalf of the attackers. It is often unrealistic to purely rely on developers to fix these vulnerabilities for two reasons: 1) it is a...
