Molecular bases of insect odorant receptor function: specificity and evolution. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Insect odorant receptors (ORs) are a class of chemoreceptors that insects use to detect volatile cues in their environment. In recent years, major advances in the field of structural biology have made it possible to obtain the first structures of insect ORs.

Coyote Range Expansion in the Human-Modified Tropics of Mesoamerica. [PDF]

Ecol Evol
Coyotes have expanded their range into southeastern Mexico, Guatemala, and Belize, increasingly occupying human‐modified landscapes. This expansion is ongoing, with rising detection rates over time and records in both disturbed and forested environments, highlighting a paradox where anthropogenic change enables native carnivore expansion.

On the properties of the Dickey-Pantula test against fractional alternatives [PDF]

, 1997
The limit properties of the testing sequence underlying the Dickey-Pantula test for a double unit root in a time series are derived when the true data generating process is assumed to be nonstationary fractionally integrated ...

Placental growth factor before 11 weeks for screening of preterm preeclampsia: The PreMoM study. [PDF]

Acta Obstet Gynecol Scand
In this multicenter study including 3448 women with singleton pregnancies in Spain, early placental growth factor (PlGF) measurement (<11 weeks) was compared with standard timing (11–13 weeks) for preterm preeclampsia screening. Early measurements showed no added benefit over models without PlGF.

Time-Domain Visualization of Electron-Phonon Coupling in Nanographenes. [PDF]

Small Methods
Impulsive vibrational spectroscopy, Raman spectroscopy, and density functional theory calculations are gathered together to unveil elusive low‐frequency collective vibrational modes in dibenzo[hi,st]ovalene nanographenes, enabling the detailed comparison between vibrational modes in derivatives with different peripheral groups.

Instrumental Variable Interpretation of Cointegration with Inference Results for Fractional Cointegration [PDF]

, 2002
In this paper we propose an alternative characterization of the central notion of cointegration, exploiting the relationship between the autocovariance and the cross-covariance functions of the series.

Asymptotic inference results for multivariate long-memory processes [PDF]

, 2004
In this paper, we extend the well-known Sims, Stock and Watson (SSW)(Sims et al. 1990; Econometrica 56, 113?44), analysis on estimation and testing in vector autoregressive process (VARs) with integer unit roots and deterministic components to a more ...

Conceptual schemes and empiricism: what Davidson saw and McDowell missed [PDF]

, 2007
This paper is an examination and evaluation of McDowell’s criticisms of Davidson’s views on conceptual schemes and empiricism. I will argue that McDowell does not understand the real nature of Davidson’s arguments against the scheme-content dualism and ...
