\(Q\)-soft \(R\)-submodules and their properties

2022
Summary: The purpose of this paper is to define the concept of \(Q\)-soft \(R\)-submodules over commutative rings and discuss their relationship with \(R\)-submodules. Next, We describe some of the their basic preoperties and discuss the master properties of them. Later, we introduce the concepts of sum, intersection and external direct sum of them and

Fragmented property rights and R&D competition [PDF]

open access: possible, 2006
Where product innovation requires several complementary patents, fragmented property rights can be a factor that limits firms’ willingness to invest in the development and commercialization of new products. This paper studies multiple simultaneous R&D contests for complementary patents and how they interact with patent portfolios that firms may ...

Tensor products, asymptotic intertwinings and property (R)

Rendiconti del Circolo Matematico di Palermo, 2011
An operator \(T\) on a complex Banach space has property \((R)\) if \(\mathrm{iso}(\sigma_{ap}(T))\setminus \sigma_{SF+}(T)=\pi_{00}(T)\), where \(\mathrm{iso}(\sigma_{ap}(T))\) are the isolated points of the approximate point spectrum, \(\sigma_{SF+}(T)\) is the upper semi-Fredholm spectrum of \(T\), and \(\pi_{00}(T)\) is the set of all isolated ...

R&D outsourcing and intellectual property infringement

Research Policy, 2015
We empirically address value appropriation hazards when firms enter into external relationships in search for innovation. Using firm-level data from Germany we document a positive link between R&D outsourcing and intellectual property infringement.

Transport properties of R Co70B30 and R Fe80B20 amorphous alloys

Journal of Magnetism and Magnetic Materials, 1991
Abstract The resistivity and magnetoresistance of RxCo70-xB30 and RxFe80-xB20 (R = Y, Pr, Sm, Tb, Dy, Ho, Er, Tm; 0 ≤ x ≤ 8) amorphous alloys are investigated. The transverse magnetoresistance increases with growth of x in all investigated ribbons and the temperature resistivity coefficient becomes negative.

Antihypertensive properties of ketanserin (R 41 468).

Federation proceedings, 1983
The serotonergic receptor antagonist 3-{2-[4-(4-fluorobenzoyl)-1-piperidinyl]ethyl}-2,4-[1H,3H] quinazolinedione (ketanserin) causes dose-dependent inhibition of the effects of 5-hydroxytryptamine (5-HT) on 5-HT2-serotonergic receptors. These receptors mediate facilitation of platelet aggregation, direct vasoconstriction in several arteries and veins ...
