In the course of our investigations of new sources of higher plant lipids, seed fatty acid compositions and the tocochromanol contents of Salvia bracteata, S. euphratica var. euphratica, S. aucherii var. canascens, S. cryptantha, S. staminea, S. limbata, S. virgata, S. hypargeia, S. halophylla, S. syriaca and S. cilicica were investigated using GLC and HPLC systems. Some of the species are ende...
Identifying the most influential spreaders is one of outstanding problems in physics of complex systems. So far, many approaches have attempted to rank the influence of nodes but there is still the lack of accuracy to single out influential spreaders. Here, we directly tackle the problem of finding important spreaders by solving analytically the expected size of epidemic outbreaks when spreadin...
IMPORTANCE Major depressive disorder (MDD) has been linked to imbalanced communication among large-scale brain networks, as reflected by abnormal resting-state functional connectivity (rsFC). However, given variable methods and results across studies, identifying consistent patterns of network dysfunction in MDD has been elusive. OBJECTIVE To investigate network dysfunction in MDD through a m...
PURPOSE The low dose rate brachytherapy procedure would benefit from an intraoperative postimplant dosimetry verification technique to identify possible suboptimal dose coverage and suggest a potential reimplantation. The main objective of this project is to develop an efficient, operator-free, intraoperative seed detection technique using the imaging modalities available in a low dose rate bra...
We show that with every separable calssical Stäckel system of Benenti type on a Riemannian space one can associate, by a proper deformation of the metric tensor, a multi-parameter family of non-Hamiltonian systems on the same space, sharing the same trajectories and related to the seed system by appropriate reciprocal transformations. These system are known as bi-cofactor systems and are integr...
In this paper we introduced an algebraic semantics for process algebra in form of abstract data types. For that purpose, we developed a particular type ofΣ algebra, the seed algebra, which describes exactly the behavior of a process within a labeled transition system. We have shown the possibility of characterizing the bisimulation of two processes with the isomorphism of their corresponding se...
A research was conducted in Southern Italy to study the changes in seed yield, oil content andfatty acids composition, in response to irrigation at different stages of growing season (at sowing,Dry; from sowing to beginning of flowering, S-BF; from visible bud to 75% flowering, VB-FF;from beginning of flowering to seed ripening, BF-M; from sowing to seed ripening, Full), in astandard sunflower ...
The role of seed systems in nutrition smallholder farmers has received little attention. This review mapped evidence impact on nutrition, identifying themes from 43 studies as direct supply, improving access, and adoption improved seed. Results had more positive than mixed/negative impacts food security, household resilience, dietary quality, diversity and/or status. Studies were skewed towards...
