In a quasi-linear environment we characterize the boundaries of the set of transfers which implement a given allocation rule (extremal transfers). Doing so allows us to generalize and unify several existing results of the mechanism design literature. More specifically, our approach delivers a characterization result for the set of implementable allocation rules. Second, we obtain an exact chara...

For a smooth fibre bundle F i −→ E p −→ B where F is a compact manifold with or without boundary, a vertical vector field V gives rise to a transfer τ V as an S-map. Our goal is to show these transfers satisfy an equation analogous to one that the index of vector fields satisfy. This equation gives results involving equivariant vector fields as well as a characterization of those transfers defi...

We introduce twin neural network (TNN) regression. This method predicts differences between the target values of two different data points rather than targets themselves. The solution a traditional regression problem is then obtained by averaging over an ensemble all predicted unseen point and training points. Whereas ensembles are normally costly to produce, TNN intrinsically creates predictio...

When are economic interactions mediated by prices and transfers, and when are they mediated by variations in the continuation payoffs within a relationship? To address this question, we examine a relationship between two players who periodically face opportunities to undertake randomly generated “projects” that impose a cost on one player and a benefit on the other, as well as opportunities to ...

Objectives: Herbal medicine is known as a valid alternative treatment. Salvia Reuterana, which has been used in the Iranian traditional medicine, is mostly distributed in the central highlands of Iran. Salvia Reuterana is a medicinal herb with various therapeutic usages. The aim of the present review is to take account of pharmacological properties of Salvia Reuterana. Materials and Methods: Th...

Abstract Transition metal dichalcogenides (TMDs) have attracted much attention in the fields of valley- and spintronics due to their property forming valley-polarized excitons when illuminated by circularly polarized light. In TMD-heterostructures it was shown that these electron-hole pairs can scatter into interlayer exciton states, which exhibit long lifetimes a twist-angle dependence. Howeve...

The demand for intensive care has increased relentlessly over the past 30 years. It is now regarded as a necessity rather than a luxury. The provision of intensive care has lagged behind that demand. Thus, patients who are judged to need intensive care when a bed is unavailable are increasingly transferred to another hospital for such care. The present commentary discusses intensive care transf...

This paper shows that, when the supply side dynamics is modelled along the lines suggested by the endogenous growth literature, it is possible that properly designed unfunded schemes would promote growth. The reduction in savings when an intergenerational transfer programme is introduced has a negative impact on capital accumulation and output. However, in the long run the saving rate will be g...

In nerve transfer, we transfer a physiologically active nerve to a distal, more important but irreparably paralyzed nerve. This surgical procedure is best done early within 6 months of the injury. Nerve transfer can be broadly classified into four categories: (1) Extraplexal; (2) Intraplexal and (3) Targeted nerve transfer. Prime extraplexal donors are the spinal accessory, phrenic and intercos...

In the presence of endogenous growth intergenerational transfer from the young to the old reduce per capita income growth and harm future generations. On the other hand, competitive equilibria are inefficient if externalities sustain long-run growth. This paper shows that if individuals retire in the last period of their life, the inefficiency of the market economy can be removed by an investme...
