Modeling tick-by-tick realized correlations
We propose a tree-structured heterogeneous autoregressive (tree-HAR) process as a simple and parsimonious model for the estimation and prediction of tick-by-tick realized correlations. The model can account for different time and other relevant predictors’ dependent regime shifts in the conditional mean dynamics of the realized correlation series. Testing the model on S&P 500 and 30-year treasu...
متن کاملTick bite prevention and tick removal.
Ticks are small blood feeding ectoparasites with a global distribution. They are important vectors of disease pathogens including rickettsiae, spirochaetes, and viruses. Prevention of tick attachment and rapid removal reduce the risk of contracting tickborne diseases, and there are many recommendations on how to achieve this. This article aims to review the evidence base for tick bite preventio...
متن کاملTick Talk
Three experiments on the production of time expressions are reported. In each experiment, speakers produced time expressions to analog clock faces while their eye movements were recorded with a headband-mounted eye tracker. Previous work has shown that speakers can apprehend the visualconceptual information in a clock display very quickly, and that this is followed by relatively slow, increment...
متن کاملTick-host conflict: immunoglobulin E antibodies to tick proteins in patients with anaphylaxis to tick bite
Tick-borne infectious diseases and allergies are a growing problem worldwide. Tick bite allergy has been associated with the direct effect of immunoglobulin E (IgE) response to tick salivary antigens, or secondary to the induction of allergy to red meat consumption through IgE antibodies against the carbohydrate α-Gal (Gal α 1-3Gal β 1-(3)4GlcNAc-R). However, despite the growing burden of this ...
متن کاملTick lysozymes
Ticks are blood feeding arthropod parasites transmitting a wide variety of pathogens to their vertebrate hosts. The vector capability of ticks is tightly linked to their immune system. Ticks can defend themselves against microbial infection with a variety of antimicrobial peptides comprising lysozymes, defensins, and unique molecules not found in other arthropods. Lysozymes are hydrolytic enzym...
