The thinning of loblolly pine plantations has a great potential to influence the fluxes and storage of carbon within managed stands. This study looked at the effects of thinning on aboveground carbon and mineral soil carbon storage, 14-years after the thinning of an 8-year-old loblolly pine plantation on the piedmont of Virginia. The study also examined soil respiration for one year following t...

We were very interested to read of a second mutation in the seed region of miR-184 resulting in EDICT syndrome. We were unsure after reading the paper, however, of how the corneal findings should be classified and of the statement that the family “does not demonstrate a keratoconus phenotype.” Keratoconus, the commonest disorder of corneal thinning and steepening, has been linked with VSX1 and ...

(1) The effects of facilitation on the structure and dynamics of plant populations have not been studied so widely as competition. The UV-B radiation, as a typical environmental factor causing stress, may result in direct stress and facilitation. (2) The effects of UV-B radiation on intraspecific competition and facilitation were investigated based on the following three predictions on self-thi...

to the glass transition in dense colloidal dispersions using asymptotic expansions in the schematic F (γ̇) 12 model of mode coupling theory. The shear thinning of the viscosity in fluid states and the yielding of glassy states is discussed. At the transition between fluid and shear-molten glass, simple and generalized Herschel-Bulkley laws are derived with power law exponents that can be compute...

The availability of large 3D datasets has made volume thinning essential for compact representation of shapes. The density of the skeletal structure resulting from the thinning process depends on the application. Current thinning techniques do not allow control over the density and can therefore address only specific applications. In this paper, we describe an algorithm which uses a thinness pa...

In this paper, we propose a new concept, thinning-out, for reducing the number of trials in skill discovery. Thinning-out means to skip over such trials that are unlikely to improve discovering results, in the same way as “pruning” in a search tree. We show that our thinningout technique significantly reduces the number of trials. In addition, we apply thinning-out to the discovery of good phys...

This paper reports on a generic sequential thinning algorithm to thin both Bangla and English characters and numerals. In this algorithm the thinned image is obtained by making the whole image uniform at first and then thinning it by deleting the unnecessary pixels by a new approach. To avoid distortion of the original character after thinning, a special technique is adopted here. This algorith...

Secondary succession is changing the character of many temperate forests and often leads to closed-canopy stands. In such forests set aside for conservation, habitat management alternatives need to be tested experimentally, but this is rarely done. The Swedish Oak Project compares two often debated alternatives: minimal intervention and non-traditional active management (conservation thinning) ...

PURPOSE To identify systemic risk factors for sickle cell maculopathy, and to analyze the microstructure of the macula of Sickle Cell Disease (SCD) patients by using automated segmentation of individual retinal layers. METHODS Thirty consecutive patients with SCD and 30 matched controls underwent spectral-domain optical coherence tomography (SD-OCT) and automated thickness measurement for eac...

Electrical and mechanical impacts of wafer bonding and thinning processes required for threedimensional (3D) IC fabrication have been evaluated with interconnect structures. In addition to the bonding and thinning required for a two-level 3D IC stack, an additional bonding and thinning process is used along with dielectric glue ashing to expose the previously tested interconnect structures. Thi...
