Existence, uniqueness and stability analysis of allelopathic stimulatory phytoplankton model

Abbas, Syed ; Banerjee, Malay ; Hungerbühler, Norbert

In: Journal of Mathematical Analysis and Applications, 2010, p. -

In this paper we consider the two species competitive delay plankton allelopathy stimulatory model system. We show the existence and uniqueness of the solution of the deterministic model. Moreover, we study the persistence of the model and the stability properties of its equilibrium points. We illustrate the theoretical results by some numerical simulations.

The linear barycentric rational method for a class of delay Volterra integro-differential equations

Abdi, Ali ; Berrut, Jean–Paul ; Hosseini, Seyyed Ahmad

In: Journal of Scientific Computing, 2018, vol. 75, no. 3, p. 1757–1775

A method for solving delay Volterra integro-differential equations is introduced. It is based on two applications of linear barycentric rational interpolation, barycentric rational quadrature and barycentric rational finite differences. Its zero–stability and convergence are studied. Numerical tests demonstrate the excellent agreement of our implementation with the predicted convergence...

Compétences en culture informationnelle à l'Université de Fribourg : planification de sessions de formation pour les étudiants en langues et littératures slaves

Abdieva Schuetz, Altynay ; Feitknecht, Regula (Dir.) ; Mégevand, Sophie (Codir.)

Mémoire de Certificate of Advanced Studies (CAS) : Université de Fribourg, 2017.

La formation en culture informationnelle permet aux étudiants, dans l’environnement d’abondance informationnelle actuelle, d’identifier des besoins en information, de localiser l’information, de l’évaluer et de l’utiliser de manière critique et éthique. Ces compétences sont le mieux acquises lors d’une formation complète. Le présent travail final se propose d’explorer les...

Nondiffusive fluxes in a Brownian system with Lorentz force

Abdoli, I. ; Vuijk, H. D. ; Sommer, J. U. ; Brader, Joseph M. ; Sharma, Abhinav

In: Physical Review E, 2020, vol. 101, no. 1, p. 012120

The Fokker-Planck equation provides a complete statistical description of a particle undergoing random motion in a solvent. In the presence of Lorentz force due to an external magnetic field, the Fokker-Planck equation picks up a tensorial coefficient, which reflects the anisotropy of the particle's motion. This tensor, however, cannot be interpreted as a diffusion tensor; there are...

3-Mercaptopyruvate sulfurtransferase supports endothelial cell angiogenesis and bioenergetics

Abdollahi Govar, Armita ; Törő, Gábor ; Szaniszlo, Peter ; Pavlidou, Athanasia ; Bibli, Sofia‐Iris ; Thanki, Ketan ; Resto, Vicente A. ; Chao, Celia ; Hellmich, Mark R. ; Szabo, Csaba ; Papapetropoulos, Andreas ; Módis, Katalin

In: British Journal of Pharmacology, 2020, vol. 177, no. 4, p. 866–883

During angiogenesis, quiescent endothelial cells (ECs) are activated by various stimuli to form new blood vessels from pre‐existing ones in physiological and pathological conditions. Many research groups have shown that hydrogen sulfide (H2S), the newest member of the gasotransmitter family, acts as a proangiogenic factor. To date, very little is known about the regulatory role of...

Seismotectonic analysis around the Mont Terri rock laboratory (Switzerland): a pilot study

Abednego, Martinus ; Blascheck, Patrick ; Schefer, Senecio ; Nussbaum, Christophe ; Joswig, Manfred ; Bossart, Paul ; Mosar, Jon

In: Swiss Journal of Geosciences, 2017, vol. 110, no. 1, p. 233–251

For this pilot study we used recorded seismic events from the SED permanent network and data from a dedicated SNS network to improve the seismotectonic understanding of very weak seismicity in the vicinity of the Mont Terri underground laboratory. We combined field data on faults with microseismic events and modelling of stress and focal mechanisms. Eighty-six events with very low magnitudes...

Vertragsfreiheit im 19. Jahrhundert – Mythologie und das Schweigen der Quellen : Rezensions-Essay zu Sibylle Hofer: Freiheit ohne Grenzen? privatrechtstheoretische Diskussionen im 19. Jahrhundert, Mohr (Siebeck): Tübingen 2001, 313 pp., Jus Publicum Vol. 53, ISBN 3-16-147576-3 = Freedom of Contract in the 19th Century: Mythology and the Silence of the Sources

Abegg, Andreas

In: Zeitschrift für Schweizerisches Recht, 2005, vol. 1, p. 73-82

Der Autor rezensiert die Habilitationsschrift von Hofer zur Vertragsfreiheit im 19. Jahrhundert und lobt deren wissenschaftliche Erfassung der privatrechtlichen Freiheitskonzeptionen des 19. Jahrhunderts. Allerdings blendet Hofer die gesellschaftlichen Kontexte des 19. Jahrhunderts fast vollständig aus, womit sie die späte diskursive Emergenz der Vertragsfreiheit um 1900 und deren...

Freedom of Contract in the 19th Century: Mythology and the Silence of the Sources : Review Essay – Sibylle Hofer’s Freiheit ohne Grenzen? privatrechtstheoretische Diskussionen im 19. Jahrhundert

Abegg, Andreas ; Thatcher, Annemarie

In: German Law Journal, 2004, vol. 5, p. 101-114

In her legal history postdoctoral Habilitation-study Freiheit ohne Grenzen? (Unlimited Freedom?), Sibylle Hofer comes to the conclusion that despite a large absence of discourse on contractual freedom the perception of unlimited freedom in the 19th Century private law theorie cannot be confirmed, instead this is more of a myth. By exploring the larger context of societal development at the end of...
