Tick size and price diffusion [PDF]

arXiv, 2010
A tick size is the smallest increment of a security price. It is clear that at the shortest time scale on which individual orders are placed the tick size has a major role which affects where limit orders can be placed, the bid-ask spread, etc. This is the realm of market microstructure and there is a vast literature on the role of tick size on market ...

Analysis of Binarized High Frequency Financial Data [PDF]

, 2005
A non-trivial probability structure is evident in the binary data extracted from the up/down price movements of very high frequency data such as tick-by-tick data for USD/JPY. In this paper, we analyze the Sony bank USD/JPY rates, ignoring the small deviations from the market price.

Mixtures of compound Poisson processes as models of tick-by-tick financial data [PDF]

, 2006
A model for the phenomenological description of tick-by-tick share prices in a stock exchange is introduced. It is based on mixtures of compound Poisson processes. Preliminary results based on Monte Carlo simulation show that this model can reproduce various stylized facts.

The Impacts of Climate Change on Ticks and Tick-Borne Disease Risk.

Annual Review of Entomology, 2021
Ticks exist on all continents and carry more zoonotic pathogens than any other type of vector. Ticks spend most of their lives in the external environment away from the host and are thus expected to be affected by changes in climate.

Tick Immune System: What Is Known, the Interconnections, the Gaps, and the Challenges

Frontiers in Immunology, 2021
Ticks are ectoparasitic arthropods that necessarily feed on the blood of their vertebrate hosts. The success of blood acquisition depends on the pharmacological properties of tick saliva, which is injected into the host during tick feeding.

Surveillance of Borrelia miyamotoi-carrying ticks and genomic analysis of isolates in Inner Mongolia, China

Parasites & Vectors, 2021
Background Borrelia miyamotoi is a newly described relapsing fever spirochete transmitted by ixodid tick species. Little is known about the prevalence of B. miyamotoi infections in humans and ticks in Inner Mongolia, China. Therefore, we investigated the
