Toscana Virus Epidemiology: From Italy to Beyond

Toscana virus (TOSV) is an arthropod-borne virus which is transmitted to humans by Phlebotomus spp sandflies. Infection is the cause of brain injuries, such as aseptic meningitis and meningoencephalitis, in Italy mainly during the summer. More recently some unusual clinical manifestations due to TOSV with severe sequelae, such as ischemic complications and hydrocephalus, have been reported. TOS...

Lecture 11 — March 22 , 2012

Before presenting any integer data structures, we present some models for computations with integers (both to precisely state what we are looking for, and as a framework to prove lower bounds). In each model, memory is arranged as a collection of words of some size (and potentially a small amount of working memory), and a fixed cost is charged for each operation. We also always make the fixed u...

2.1 Regression Problem Statement Given A ∈ Rn×d and b ∈ Rn, Find x ∈ Rd minimizing ‖Ax− b‖2. (n d) A is given data composed of n rows of size d which indicates the d different features. And for those n items, vector b is composed of n outcomes corresponding to each 1× d feature vector. By finding solution x ∈ minimizing ‖Ax− b‖2, we can find an approximate linear mapping between A and b via x: ...

Macroporous silicon has been etched from n-type Si, using a vertical etching cell where no rear side contact on the silicon wafer is necessary. The resulting macropores have been characterised by means of Scanning Electron Microscopy (SEM). After etching, SiO2 was thermally grown on the top of the porous silicon as an insulating layer and Si3N4 was deposited by means of Low Pressure Chemical Va...
