Glandular secreting trichomes of cultivated tomato (Solanum lycopersicum) produce a wide array of volatile and nonvolatile specialized metabolites. Many of these compounds contribute to the characteristic aroma of tomato foliage and constitute a key part of the language by which plants communicate with other organisms in natural environments. Here, we describe a novel recessive mutation called ...

OBJECTIVE To compare rates of fatal drug-related overdose death (OD) cases--a major harm outcome of illicit substance use--in the two provinces of British Columbia (BC) and Ontario, and the two largest municipalities in those provincial jurisdictions, namely the cities of Vancouver and Toronto, between 1992 and 2004. METHODS Provincial coroners' data of drug-related OD cases for the provincia...

Optic disc (OD) appearance in fundus images is one of the clinical indicators considered in the assessment of retinal diseases such as glaucoma. The cup-to-disc ratio (CDR) is the most common clinical measurement used to characterize glaucoma. However, the CDR only evaluates the relative sizes of the cup and the OD via their diameters. We propose to construct an atlas-based shape descriptor (AS...

We report on a study of the vibrational energy relaxation and resonant vibrational (Förster) energy transfer of the OD vibrations of D2O and mixtures of D2O and H2O using femtosecond mid-infrared spectroscopy. We observe the lifetime of the OD vibrations of bulk D2O to be 400 +/- 30 fs. The rate of the Förster energy transfer is measured via the dynamics of the anisotropy of the OD vibrational ...

Origin-destination (OD) matrices are essential for various analyses in the field of traffic planning, and they are often estimated from link flow observations. We compare strategies for allocating link flow detectors to a traffic network with respect to the quality of the estimated OD-matrix. First, an overview of allocation strategies proposed in the literature is presented. Second, we give an...

Gama amino butyric acid (GABA) inhibition plays an important role in the onset and offset of the critical period for ocular dominance (OD) plasticity in the primary visual cortex. Previous studies have focused on the involvement of GABAA receptors, while the potential contribution of GABAB receptors to OD plasticity has been neglected. In this study, the GABAB receptor antagonist SCH50911 or ag...

BACKGROUND Substance misuse is associated with cognitive dysfunction. We used a stop signal task to examine deficits in cognitive control in individuals with opioid dependence (OD). We examined how response inhibition and post-error slowing are compromised and whether methadone maintenance treatment (MMT), abstinence duration, and psychiatric comorbidity are related to these measures in individ...

Background Olfactory dysfunction (OD) in old age is associated with poor health outcomes. Interrelationships among different correlates of OD can offer insights into the underlying mechanisms, but to date remain understudied. Methods Odor identification performance and self-reported olfactory functioning were studied in 2,234 people aged 60-90 years, who were free of neurodegenerative disease...

We deduce rigorous conditions for the onset of amplitude death (AD) and oscillation death (OD) in a system of identical coupled paradigmatic Stuart-Landau oscillators. A nonscalar coupling and high frequency are beneficial for the onset of AD. In strong contrast, scalar diffusive coupling and low intrinsic frequency are in favor of the emergence of OD. Our finding contributes to clearly disting...

With HOD initially in its vibrational ground state, we present a new detailed interpretation of the OD/OH branching ratio (approximately 3) in the photoinduced process D+OH<--HOD-->H+OD, in the first absorption band. Using semiclassical arguments, we show that the branching ratio has little to do with the initial distribution of configurations, but the initial momentum distribution plays a key ...
