Employees of the Forest Research Institute (FRI) KarRC RAS have contributed greatly to study biodiversity vascular plants, aphyllophoroid, sac and basidial fungi lichens Republic Karelia. Studies plants various groups been carried out since FRI foundation in 1957 are continuing successfully at present, with new tasks being set geographic range interests expanding cover entire Northwest Russia. ...

The autonomous floral promotion pathway plays a key role in the regulation of flowering in rapid-cycling Arabidopsis (Arabidopsis thaliana) by providing constitutive repression of the floral inhibitor FLOWERING LOCUS C (FLC). As a result, autonomous pathway mutants contain elevated levels of FLC and are late flowering. Winter annual Arabidopsis, in contrast, contain functional alleles of FRIGID...

The focus of this paper is the problem of foot rotation in biped robots during the single support phase. Foot rotation is an indication of postural instability and should be carefully treated in a dynamically stable walk and avoided altogether in a statically stable walk. We introduce the foot rotation indicator (FRI) point which is a point on the foot/ground contact surface where the net groun...

In the absence of observation noise, it is known that it is possible to develop exact sampling schemes for a large class of parametric nonbandlimited signals, namely, certain signals of finite rate of innovation (FRI signals), either periodic or aperiodic, such as streams of Diracs, nonuniform splines or piecewise polynomials. A common feature of such signals is that they have a finite number o...

Capsella rubella is an inbreeding annual forb closely related to Arabidopsis thaliana, a model species widely used for studying natural variation in adaptive traits such as flowering time. Although mutations in dozens of genes can affect flowering of A. thaliana in the laboratory, only a handful of such genes vary in natural populations. Chief among these are FRIGIDA (FRI) and FLOWERING LOCUS C...

Matched resolution multi-frequency VLA observations of four radio galaxies are used to derive the asymptotic low energy slope of the relativistic electron distribution. Where available, low energy slopes are also determined for other sources in the literature. They provide information on the acceleration physics independent of radiative and other losses, which confuse measurements of the synchr...

Thellungiella halophila (T. halophila) (salt cress) is a close relative of Arabidopsis and a model plant for salt tolerance research. However, the nature of its later flowering causes some difficulties in genetic analysis. The FRIGIDA (FRI) gene plays a key role in the Arabidopsis vernalization flowering pathway, whose homolog in T. halophila may also be a key factor in controlling flowering ti...

OBJECTIVES Amoxicillin use has been reported to be associated with developmental defects on enamel surfaces. This analysis assessed the association between amoxicillin use and fluorosis on late-erupting permanent teeth. METHODS As part of the Iowa Fluoride Study, subjects were followed from birth to 32 months with questionnaires every 3-4 months to gather information on fluoride intake and am...
