Habituation with apparatus and group testing improves assessment of fish preferences

Journal of Fish Biology, EarlyView.
Abstract Preference tests are commonly used to assess fish behavior and cognition in several research fields. This study aimed to investigate how fish perform in a preference test involving extended habituation to the apparatus, which was expected to reduce stress.

Synthesis of Bioactive 2-(Arylamino)thiazolo[5,4-f]-quinazolin-9-ones via the Hügershoff Reaction or Cu- Catalyzed Intramolecular C-S Bond Formation

Molecules, 2016
A library of thirty eight novel thiazolo[5,4-f]quinazolin-9(8H)-one derivatives (series 8, 10, 14 and 17) was prepared via the Hügershoff reaction and a Cu catalyzed intramolecular C-S bond formation, helped by microwave-assisted technology when required.

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.

COBRA: A combined regression strategy

Journal of Multivariate Analysis, 2016
A new method for combining several initial estimators of the regression function is introduced. Instead of building a linear or convex optimized combination over a collection of basic estimators $r_1,\dots,r_M$, we use them as a collective indicator of the proximity between the training data and a test observation. This local distance approach is model-

Causal inference under multiple versions of treatment [PDF]

, 2011
In this article we discuss the no-multiple-versions-of-treatment assumption and extend the potential outcomes framework to accommodate causal inference under violations of this assumption.

Effect of surface treatments on the bond strength between additively manufactured or injection‐molded high‐performance polymers and titanium

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the effect of surface treatment and fabrication techniques of high‐performance polymers on their shear bond strength (SBS) to grade IV titanium. Materials and Methods A total of 120 pre‐milled titanium abutments were sectioned.

COBRA: a new European research project for organic plant breeding [PDF]

, 2013
Development of organic plant breeding and seed production will have a valuable impact on organic plant production. Breeding of plant material adapted for organic agriculture is crucial in order to cope with stresses such as climate change, weeds and seed

A comparative phylogenetic approach for the evolution of melanism in elapid snakes supports the Bogert's rule

Journal of Zoology, EarlyView.
The adaptive function of melanistic colourations across the animal kingdom has been matter of debate for decades and for reptiles the biogeographic Bogert's rule has been frequently advocated: darker where colder to enhance thermoregulation. The broad geographic distribution which encompasses a wide range of climatic conditions render Elapidae an ...
