On some conditionally solvable quantum-mechanical problems
(IOP Publishing, 2020-09-03)
We analyze two conditionally solvable quantum-mechanical models: a one-dimensional sextic oscillator and a perturbed Coulomb problem. Both lead to a three-term recurrence relation for the expansion coefficients. We show ...
Gross misinterpretation of a conditionally solvable eigenvalue equation
(World Scientific, 2020-11-10)
We solve an eigenvalue equation that appears in several papers about a wide range of physical problems. The Frobenius method leads to a three-term recurrence relation for the coefficients of the power series that, under ...
Intense and sustained pain reduces cortical responses to auditory stimuli: Implications for the interpretation of the effects of heterotopic noxious conditioning stimulation in humans
(Wiley Blackwell Publishing, Inc, 2019-08)
Phasic pain stimuli are inhibited when they are applied concomitantly with a conditioning tonic stimulus at another body location (heterotopic noxious conditioning stimulation, HNCS). While the effects of HNCS are thought ...
Ethanol-induced locomotor activity in adolescent rats and the relationship with ethanol-induced conditioned place preference and conditioned taste aversion
(Wiley, 2012-05)
Adolescent rats exhibit ethanol-induced locomotor activity (LMA), which is considered an index of ethanol's motivational properties likely to predict ethanol self-administration, but few studies have reported or correlated ...
Female choice, male dominance and condition-related traits in the polygynous subterranean rodent Ctenomys talarum
(Elsevier Science, 2017-09)
Ctenomys talarum is a solitary and highly territorial species in which dominant males aggressively deter other males and monopolize reproductive activity. Female preference for dominant males is not easy to assess due to ...
On the quiver with relations of a quasitilted algebra and applications
(Taylor, 2016-12)
In this paper we discuss, in terms of quiver with relations,sufficient and necessary conditions for an algebra to be a quasitiltedalgebra. We start with an algebra with global dimension at most twoand we give a sufficient ...
A Sequential Optimality Condition Related to the Quasi-normality Constraint Qualification and Its Algorithmic Consequences
(Society for Industrial and Applied Mathematics, 2019-03)
In the present paper, we prove that the augmented Lagrangian method converges to KKT pointsunder the quasinormality constraint qualification, which is associated with the external penalty theory. An interesting consequence ...
Male mating success is related to body condition and stress-induced leukocyte response in an anuran with scramble competition
(National Research Council Canada-NRC Research Press, 2020-06)
Competition among males can be a decisive factor for successful mating in anuranexplosive breeders with a male-biased population sex ratio. The Yungas Red-belly toad Melanophryniscus rubriventris (Vellard, 1947) is an ...
Palatini wormholes and energy conditions from the prism of general relativity
(Springer, 2017-11)
Wormholes are hypothetical shortcuts in spacetime that in general relativity unavoidably violate all of the pointwise energy conditions. In this paper, we consider several wormhole spacetimes that, as opposed to the standard ...
Effect of nursery ground variability on condition of age 0+ year Merluccius hubbsi
(Wiley Blackwell Publishing, Inc, 2018-12)
This study examined the southern or Patagonian (41°–55° S) stock of Argentine hake Merluccius hubbsi, the more abundant of the two stocks on the Argentinean continental shelf. Pre-recruits (age 0+ year individuals) of this ...
