Towards mainstreaming of shared spaces as a basis for sustainable wellbeing for all

Like other rich countries, Switzerland is using energy and material at a per-capita rate far above the world average, contributing to multiple crises of climate, biodiversity, pollution, and numerous factors of human wellbeing, especially health, inequalit ...

Eco-morphodynamic carbon pumping by the largest rivers in the Neotropics

Paolo Perona

The eco-morphodynamic activity of large tropical rivers in South and Central America is analyzed to quantify the carbon flux from riparian vegetation to inland waters. We carried out a multi-temporal analysis of satellite data for all the largest rivers in ...

Global Climate Change Mitigation: Strategic Incentives

Sigit Pria Perdana

Central to global agreement on carbon emissions are strategic interactions amongst regions over abatement policy and the benefits to be shared. These are re-examined in this paper, in which benefits from mitigation stem from a meta-analysis that links carb ...

La Technologie et les brevets d'invention aux XVIIIe et XIXe siècles

Jérôme Baudry

(FR) Dans les régimes de brevets d’invention qui se mettent en place au XVIIIe siècle, d’abord en Angleterre puis aux États-Unis et en France, la description (par le texte, l’image, le modèle, l’échantillon) occupe un rôle central. Elle permet d’opérationn ...

Nuove ecologie alpine: industrializzazione e costruzione della città-territorio

Roberto Sega

This research study offers a reflection on the Alpine urban condition through the observation of the spaces of production. Departing from the premise that the tourist economy cannot be the only possible horizon for Alpine development, this thesis reflects ...

Do It Yourself: From Individual Sovereignty to Civic Design

Matthew Skjonsberg

With the Usonian Automatic construction system, Frank Lloyd Wright provided citizens of Usonia—Wright’s preferred term for a culturally advanced North America—with the means of “doing it themselves,” of building their own homes and communities. Though desi ...

Tunable insertion of multiple lines into a Kerr frequency comb using electro-optical modulators

Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts, Yan Yan, Lin Zhang, Ahmad Fallahpour, Amirhossein Mohajerin Ariaei, Cong Liu

We experimentally insert a flexible number of electro-optical (EO) comb lines into a Kerr frequency comb via EO modulation and demonstrate the use of combined Kerr and EO combs as light sources in coherent communications. The number of EO lines inserted in ...

Imaging blood cells through scattering biological tissue using speckle scanning microscopy

Demetri Psaltis, Ye Pu, Xin Yang

We demonstrate imaging of blood cells enclosed in chicken skin tissue using speckle scanning microscopy (SSM). Clear images of multiple cells were obtained with subcellular resolution and good image fidelity, provided that the object dimension was smaller ...

Bandwidth and repetition rate programmable Nyquist sinc-shaped pulse train source based on intensity modulators and four-wave mixing

Camille Sophie Brès, Mohammad Amin Shoaie, Steevy Joyce Cordette

We propose and experimentally demonstrate an all-optical Nyquist sinc-shaped pulse train source based on intensity modulation and four-wave mixing. The proposed scheme allows for the tunability of the bandwidth and the full flexibility of the repetition ra ...

Optical characterization of two-dimensional array of 2048 tilting micromirrors for astronomical spectroscopy

Nico de Rooij, Michael David Canonica, Wilfried Noell

A micromirror array composed of 2048 silicon micromirrors measuring 200 x 100 mu m(2) and tilting by 25 degrees was developed as a reconfigurable slit mask for multi-object spectroscopy (MOS) in astronomy. The fill factor, contrast, and mirror deformation ...
