Whole-body regeneration in the colonial tunicate Botrylloides leachii

Blanchoud, Simon ; Rinkevich, Buki ; Wilson, Megan J.

In: Marine Organisms as Model Systems in Biology and Medicine, 2018, p. 337–355

The colonial marine invertebrate Botrylloides leachii belongs to the Tunicata subphylum, the closest invertebrate relatives to the vertebrate group and the only known class of chordates that can undergo whole-body regeneration (WBR). This dramatic developmental process allows a minute isolated fragment of B. leachii’s vascular system, or a colony excised of all adults, to restore a...

Introducing an e-marketplace and phygital store to the Swiss market : the key success factors for the fashion industry in Switzerland

Mustajbasic, Andrea ; Bélanger, Josée (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2018 ; TDEE 371.

The development of technology and expansion of easy internet-access has impacted customers’ lifestyles and purchasing behavior. The fast-changing digital environment has disrupted the customer journey and thus created new business models in retail. Yet neither online shopping nor offline stores are meeting customers’ needs nowadays. This paper initiates the study by defining the two key terms...

Isotope fractionation due to diffusion and sorption of chlorinated hydrocarbons and its implications for identifying reactive processes in aquifer - aquitard systems

Wanner, Philipp ; Hunkeler, Daniel (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

Des méthodes isotopiques stables ont été utilisées de plus en plus pour identifier et quantifier la transformation réactive dans la sous-surface de composés organiques tels que les hydrocarbures chlorés. La méthode générale repose sur l'hypothèse que seuls les processus réactifs sont associés à un effet isotopique. Cependant, des études récentes ont révélé que les processus...

Complexities in financial network topological dynamics: modeling of emerging and developed stock markets

Tang, Yong ; Xiong, Jason Jie ; Jia, Zi-Yang ; Zhang, Yi-Cheng

In: Complexity, 2018, p. -

Policy makings and regulations of financial markets rely on a good understanding of the complexity of financial markets. There have been recent advances in applying data-driven science and network theory into the studies of social and financial systems. Financial assets and institutions are strongly connected and influence each other. It is essential to study how the topological structures of...

Unequivocal signatures of the crossover to Anderson localization in realistic models of disordered quasi-one-dimensional materials

Lopez-Bezanilla, Alejandro ; Froufe-Pérez, Luis S. ; Roche, Stephan ; Sáenz, Juan José

In: Physical Review B, 2018, vol. 98, no. 23, p. 235423

The only unequivocal known criterion for single-parameter scaling Anderson localization relies on the knowledge of the full conductance statistics. To date, theoretical studies have been restricted to model systems with symmetric scatterers, hence lacking universality. We present an in-depth statistical study of conductance distributions P(g), in disordered ‘micrometer-long’ carbon...

Social interaction and the development of cognitive operations

Doise, Willem ; Mugny, Gabriel ; Perret-Clermont, Anne-Nelly

In: European Journal of Social Psychology, 1975, vol. 5, no. 3, p. 367-383

This paper presents two experiments to support the general hypothesis that the coordination of actions between individuals promotes the acquisition of cognitive coordinations. The first experiment shows that two children, working together, can successfully perform a task involving spatial coordinations; children of the same age, working alone, are not capable of performing the task. The second...

Secreted venom allergen-like proteins of helminths: Conserved modulators of host responses in animals and plants

Wilbers, Ruud H. P. ; Schneiter, Roger ; Holterman, Martijn H. M. ; Drurey, Claire ; Smant, Geert ; Asojo, Oluwatoyin A. ; Maizels, Rick M. ; Lozano-Torres, Jose L.

In: PLOS Pathogens, 2018, vol. 14, no. 10, p. e1007300

Despite causing considerable damage to host tissue at the onset of parasitism, invasive helminths establish remarkably persistent infections in both animals and plants. Secretions released by these obligate parasites during host invasion are thought to be crucial for their persistence in infection. Helminth secretions are complex mixtures of molecules, most of which have unknown molecular...

Seeing is better than believing: visualization of membrane transport in plants

Geisler, Markus

In: Current Opinion in Plant Biology, 2018, vol. 46, p. 104–112

Recently, the plant transport field has shifted their research focus toward a more integrative investigation of transport networks thought to provide the basis for long- range transport routes. Substantial progress was provided by of a series of elegant techniques that allow for a visualization or prediction of substrate movements in plant tissues in contrast to established quantitative...

A gardener’s influence on urban soil quality

Tresch, Simon ; Moretti, Marco ; Le Bayon, Renée-Claire ; Mäder, Paul ; Zanetta, Andrea ; Frey, David ; Fliessbach, Andreas

In: Frontiers in Environmental Science, 2018, vol. 6, p. -

Gardens are hot spots for urban biodiversity and provide habitats for many plant and animal species, both above- and below-ground. Furthermore, gardens provide a wide range of ecosystem services, including carbon (C) storage and nutrient cycling. Although the soil is the foundation of sustainable gardens providing those ecosystem services, very little is known about the consequences of garden...

Modelling protein-protein interactions to elucidate molecular mechanisms behind neurodegenerative diseases

Grasso, Gianvito ; Krause, Rolf (Dir.) ; Danani, Andrea (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO017.

The worldwide significant increase in life expectancy has recently drawn the attention of the scientific community to neurodegenerative pathologies of the elderly population. These neurodegenerative disorders arise from the abnormal protein aggregation in the nervous tissue leading to intracellular inclusions or extracellular aggregates in specific brain areas. A feasible strategy to prevent...
