Using transaction data from Indonesia, this paper shows that domestic investors have higher profits than foreign investors. In addition, clients of global brokerages have higher long-term and smaller medium (intramonth) and short (intraday) term profits than clients of local brokerages. This suggests that clients of local brokerages have a short-lived information advantage, but that clients of ...

It has been proved that almost all n-bit Boolean functions have exact classical query complexity n. However, the situation seemed to be very different when we deal with exact quantum query complexity. In this paper, we prove that almost all n-bit Boolean functions can be computed by an exact quantum algorithm with less than n queries. More exactly, we prove that ANDn is the only n-bit Boolean f...

Bilingualism can have widespread cognitive effects. In this article we investigate whether bilingualism might have an effect on adults' abilities to reason about other people's beliefs. In particular, we tested whether bilingual adults might have an advantage over monolingual adults in false-belief reasoning analogous to the advantage that has been observed with bilingual children. Using a trad...

The ΔF508 CFTR mutation, which is the commonest cause of cystic fibrosis (CF), has the highest frequency of any genetic mutation among Caucasians of central European origin. Persistence of a mutation suggests that heterozygosity for this mutation imparts some genetic advantage. We hypothesized that heterozygosity provides a selective survival advantage during influenza pneumonitis, as a result ...

Objective. To investigate whether the Glycemic Index (GI) or Glycemic Load (GL) of a diet is associated with C-reactive Protein (CRP) and risk of type 2 diabetes in a prospective study. Materials and Methods. Our analysis included 4,366 participants who did not have diabetes at baseline. During follow-up 456 diabetes cases were confirmed. Dietary GI and GL were derived from a food-frequency que...

introduction: in order to achieve a higher success rate for tympanoplasty, different techniques have been developed, and a wide variety of grafting materials have been developed. one of the techniques currently receiving considerable attention involves not lifting the remaining of eardrum from the malleus and embedding the graft underneath in order to repair the eardrum correctly in its origina...

The Affordable Care Act enacts a new payment system for private health plans available to Medicare beneficiaries through the Medicare Advantage (MA) program. The system, which is being phased in through 2017, aims to (1) reduce the excess pay­ments received by private plans relative to per capita spending in traditional Medicare, and (2) reward plans that earn high performance ratings. Using 20...
