A Rate Equation Approach to Elucidate the Kinetics and Robustness of the TGF-b Pathway (2009)

Pontus Melke, Henrik Jönsson, Evangelia Pardali, Carsten Peterson

ABSTRACT We present a rate equation model for the TGF-b pathway in endothelial cells together with novel measurements. This pathway plays a prominent role in inter- and intracellular communication...

Developmental Patterning by Mechanical Signals in Arabidopsis (2008)

Hamant, Olivier, Heisler, Marcus G., Jönsson, Henrik, Krupinski, Pawel, Uyttewaal, Magalie, Bokov, Plamen, ...

A central question in developmental biology is whether and how mechanical forces serve as cues for cellular behavior and thereby regulate morphogenesis. We found that morphogenesis at the Arabidopsis...

A SOFTWARE ARCHITECTURE FOR DEVELOPMENTAL MODELING IN PLANTS: THE COMPUTABLE PLANT PROJECT (2008)

Victoria Gor, Bruce E. Shapiro, Henrik Jönsson, Marcus Heisler, Venugopola Reddy, Elliot M. Meyerowitz, ...

Abstract: We present the software architecture of the Computable Plant Project, a multidisciplinary computationally based approach to the study of plant development. Arabidopsis thaliana is used as a...

An Information-Based Neural Approach to Generic Constraint (2008)

Henrik Jönsson, Bo Söderberg

A novel artificial neural network heuristic (INN) for general constraint satisfaction problems is presented, extending a recently suggested method restricted to boolean variables. In contrast to...

An Approximate Maximum Likelihood Approach, applied to Phylogenetic Trees (2008)

Henrik Jönsson, Bo Söderberg

A novel type of approximation scheme to the maximum likelihood (ML) approach is presented and discussed in the context of phylogenetic tree reconstruction from aligned DNA sequences. It is based on a...

Pricing Constant Maturity Credit Default Swaps Under Jump Dynamics (2008)

Henrik Jönsson, Wim Schoutens

In this paper we discuss the pricing of Constant Maturity Credit De-fault Swaps (CMCDS) under single sided jump models. The CMCDS offers default protection in exchange for a floating premium which is...

Prisspridning på den svenska e-handelsmarknaden - vilka är förklaringsfaktorerna? (2008)

Jönsson, Henrik, Omander, Christian

Vi vill med denna uppsats undersöka vilka faktorer som styr prisspridningen på den svenska e-handelsmarknaden. De faktorer som studerats är produktens pris, popularitet, bransch, antal säljare...

Self-Organization in High-Density Bacterial Colonies: Efficient Crowd Control (2007)

HoJung Cho, Henrik Jönsson, Kyle Campbell, Pontus Melke, Joshua W. Williams, Bruno Jedynak, ...

Colonies of bacterial cells can display complex collective dynamics, frequently culminating in the formation of biofilms and other ordered super-structures. Recent studies suggest that to cope with...

Fotbollens arenautveckling utifrån ett storstadsperspektiv : En nulägesanalys av arenautvecklingen i Sotckholm, Göteborg och Malmö (2007)

Ahlqvist, Christian, Jönsson, Henrik

Swedish soccer is building for the future. In the three biggest cities in Sweden new soccer stadiums are being built. Approximately 2, 5 billion Swedish crowns are being invested for this cause. In...

An auxin-driven polarized transport model for phyllotaxis (2006)

Jönsson, Henrik, Heisler, Marcus G., Shapiro, Bruce E., Meyerowitz, Elliot M., Mjolsness, Eric

Recent studies show that plant organ positioning may be mediated by localized concentrations of the plant hormone auxin. Auxin patterning in the shoot apical meristem is in turn brought about by the...

Modeling the organization of the WUSCHEL expression domain in the shoot apical meristem (2005)

Jönsson, Henrik, Heisler, Marcus, Reddy, G. Venugopala, Agrawal, Vikas, Gor, Victoria, Shapiro, Bruce E., ...

Motivation: The above-ground tissues of higher plants are generated from a small region of cells situated at the plant apex called the shoot apical meristem. An important genetic control circuit...

Controversial significance of early S100B levels after cardiac surgery (2004)

Jönsson, Henrik, Johnsson, Per, Bäckström, Martin, Alling, Christer, Dautovic-Bergh, Cecilia, Blomquist, Sten

Abstract Background The brain-derived protein S100B has been shown to be a useful marker of brain injury of different etiologies. Cognitive dysfunction after cardiac surgery using cardiopulmonary...

Modeflugor inom transportsektorn (2004)

Jönsson, Henrik

During the time I've attended the programme to become a Transportation manager, I've been presented with quite a large number of different words. My purpose with this paper is to take a closer look...

In the eye of both patient and spouse: memory is poor 1 to 2 years after coronary bypass and angioplasty. (2002)

Bergh, Cecilia, Bäckström, Martin, Jönsson, Henrik, Havinder, Lars, Johnsson, Per

BACKGROUND: The study aimed to investigate patient and spouse perception of cognitive functioning 1 to 2 years after coronary artery bypass grafting. METHODS: Seventy-six married patients who had...

Konstruktivistisk fysik i gymnasieskolan (2002)

Elmqvist, Anders, Jönsson, Henrik

Arbetet syftar till att ge exempel på hur konstruktivismen kan användas praktiskt genom olika arbetssätt inom fysikundervisningen i den svenska gymnasieskolan. Arbetssätten som tas upp är...

Variational Methods in Combinatorial Optimization and Phylogeny Reconstruction (2001)

Jönsson, Henrik

Algorithms based on the variational approach, as used in statistical physics, are developed. For constraint satisfaction problems a novel cost function, based on information-theoretic arguments, is...
