Where have all the grouse ticks gone? Apparent decline in collections of Haemaphysalis chordeilis Packard

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2022
Haemaphysalis chordeilis Packard, also known as the grouse or bird tick, is a three-host tick native to North America. Literature from the early 20th century reported a widespread distribution of this tick across the US and Canada.

A Tick-by-Tick Solution for Concentrated Liquidity Provisioning [PDF]

open access: yesarXiv
Automated market makers with concentrated liquidity capabilities are programmable at the tick level. The maximization of earned fees, plus depreciated reserves, is a convex optimization problem whose vector solution gives the best provision of liquidity at each tick under a given set of parameter estimates for swap volume and price volatility ...

Mathematical Model and Optimal Control of the Transmission Dynamics of Avian Spirochaetosis (TICK Fever) [PDF]

open access: yesarXiv, 2017
Avian Spirochaetosis is an acute endemic tick-borne disease of birds, caused by Borrelia anserins, a species of Borrelia bacteria. In this paper, we present a compartmental Mathematical model of the disease for the bird population and Tick population. The model so constructed was analyzed using methods from dynamical systems theory.

Advancing Solar Modulation Ability of Near Infrared Thermochromic Cholesteric Liquid Crystal Smart Window Films Using a Waveplate

open access: yesAdvanced Optical Materials, EarlyView.
This work presents the use of a waveplate in thermochromic materials for smart windows. The waveplate enables the optical material to transition from a narrow band reflection to broad band ambidextrous reflection upon heating, resulting in a solar transmission modulation of 5.2% which is four times greater than typical thermochromic cholesteric liquid ...

Effective and Practical Stereoselective Synthesis of Nutlins Precursors by Immobilization of Privileged Chiral Mono‐Amidine Catalyst

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract A strategy for the immobilization of Johnston's Mono(AMidine) catalyst (MAM) onto polystyrene, silica and hybrid silica‐polystyrene nanoparticles is presented. The catalyst activity was evaluated in the stereoselective aza‐Henry reaction leading to the pivotal β‐amino nitroalkane precursors of the anti‐cancer agents Nutlins (with Nutlin‐3a as ...

The clocks they are adjunctions:Denotational semantics for Clocked Type Theory [PDF]

open access: yesarXiv, 2018
Clocked Type Theory (CloTT) is a type theory for guarded recursion useful for programming with coinductive types, allowing productivity to be encoded in types, and for reasoning about advanced programming language features using an abstract form of step-indexing. CloTT has previously been shown to enjoy a number of syntactic properties including strong
