Equations describing changes of shape along the flatfish body length and their importance for sustainable and responsible fisheries [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2007
Background. The purpose of this study was to identify mathematical equations describing changes in a flatfish body shape along its longitudinal axis. The initial function for the description of a cross-section contour is the ellipse equation including a ...

The genetics of cross-sectional and longitudinal body mass index [PDF]

open access: yesBMC Genetics, 2003
AbstractThere has been a lack of consistency in detecting chromosomal loci that are linked to obesity-related traits. This may be due, in part, to the phenotype definition. Many studies use a one-time, single measurement as a phenotype while one's weight often fluctuates considerably throughout adulthood.

Inclusive breakup of three-fragment weakly bound nuclei

open access: yesPhysics Letters B, 2017
The inclusive breakup of three-fragment projectiles is discussed within a four-body spectator model. Both the elastic breakup and the non-elastic breakup are obtained in a unified framework.

Study of many-body cross sections and link with two-body cross sections and with the reaction mechanism

open access: yesNuclear Physics B, 1971
Cross sections for many-body reactions have been studied in an attempt to separate the effect of the reaction mechanism, i.e. the “physics”, from phase-space effects. The cross section σ, is written as σ=σ ×(phase-space term). The phase-space term is chosen such that at asymptotically high energies it tends to the value of one, and it has the form

Relation between shape and the phenomenon of flutter for bridge deck-like bluff bodies

open access: yesArchives of Mechanics, 2011
The paper deals with experimental analysis of the influence of cross–section shape of a body on the phenomenon of flutter. The aeroelastic section model that was the object of study in a laboratory corresponded to a central section of a long bridge deck.

On two-body and three-body spin correlations in leptonic t t ¯ Z $$ t\overline{t}Z $$ production and anomalous couplings at the LHC

open access: yesJournal of High Energy Physics, 2023
We study the anomalous t t ¯ Z $$ t\overline{t}Z $$ couplings in the t t ¯ Z $$ t\overline{t}Z $$ production in leptonic final state at the 13 TeV LHC.
