A 10-bit pipeline A/D converter using low gain (<= 40 dB) operational amplifiers (opamps) is presented. Without. interfering the normal analog-to-digital conversion, a continuous reference refreshing technique is exploited. This technique effectively reduces the gain requirement of opamp while the conversion speed is not compromised, allowing the use of simple cascode CMOS inverters. The compensat
We explore the relation between institutional quality, trust and stock-market participation. In our theoretical model, agents update their beliefs in a Bayesian manner based on observations on frauds and choose whether to invest in the stock market. The corresponding empirical model shows that institutional quality affects trust and that the part of trust that is explained by institutional quality

The study of large settlement sites with graves from the Late Mesolithic has changed our conception of this period. In western Europe sites of this kind have long been known, and are well represented in the coastal area of western Iberia. One of these sites is Poças de São Bento, located near the River Sado in southern Portugal. The results of the excavation give interesting perspectives on specif

Climate change and atmospheric aerosols are a threat for human health and life. Reducing aerosol emissions would save human lives close to the aerosol source, but could lead to more death due to the implications of a warmer climate. Aerosol particles acting as cloud or ice nuclei can induce a change in cloud properties and thus indirectly induce a change in planetary albedo, which is considered th
Phenyl β-d-galactopyranoside was found to be an efficient acceptor of l-[14C]fucose when guanosine diphosphate l-[14C]fucose was used as the donor substrate and human serum, submaxillary glands or stomach mucosa were the sources of l-fucosyltransferase. The enzyme utilising phenyl β-D-galactoside was present in the serum of donors of all ABO blood-groups examined, except those of the rare Oh (Bomb
We show that computation of all-terminal graph reliability requires time exponential in Ω(m/ log2 m) for simple graphs of m edges under the Exponential Time Hypothesis.
