100-year mass changes in the Swiss Alps linked to the Atlantic multidecadal oscillation

Huss, Matthias ; Hock, Regine ; Bauder, Andreas ; Funk, Martin

In: Geophysical Research Letters, 2010, vol. 37, p. L10501

Thirty new 100-year records of glacier surface mass balance, accumulation and melt in the Swiss Alps are presented. The time series are based on a comprehensive set of field data and distributed modeling and provide insights into the glacier-climate linkage. Considerable mass loss over the 20th century is evident for all glaciers, but rates differ strongly. Glacier mass loss shows multidecadal...

1,2,3-triazolylidenes as versatile abnormal carbene ligands for late transition metals

Mathew, Paulson ; Neels, Antonia ; Albrecht, Martin

In: Journal of the American Chemical Society, 2008, vol. 130, no. 41, p. 13534–13535

The [3 + 2] cycloaddition of azides and acetylenes followed by nitrogen quaternization was applied for the generation of novel and highly modular triazolium salts. The selective substitution of the 1,3,4-substitution pattern presets such salts as precursors for a new class of abnormal carbene ligands, thus expanding the family of these high-impact ligands. Metalation of the triazolium salts is...

1,4-Dimethylenespiropentane: a unique model system for studying fermi resonance in raman optical activity

Hug, Werner ; Haesler, Jacques ; Kozhushkov, Sergei I. ; Meijere, Armin de

In: ChemPhysChem, 2007, vol. 8, no. 8, p. 1161 - 1169

The C₂-symmetric title compound, a small, rigid hydrocarbon molecule with two distinct, strongly interacting vibrational chromophores, represents a unique model system for testing computational approaches to Raman optical activity (ROA) beyond the isolated molecule and the harmonic approximation. We show that the experimental Raman and ROA spectra are marked by the presence of strong Fermi...

17-β estradiol increases parvalbumin levels in Pvalb heterozygous mice and attenuates behavioral phenotypes with relevance to autism core symptoms

Filice, Federica ; Lauber, Emanuel ; Vörckel, Karl Jakob ; Wöhr, Markus ; Schwaller, Beat

In: Molecular Autism, 2018, vol. 9, p. 15

Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders characterized by two core symptoms: impaired social interaction and communication, and restricted, repetitive behaviors and interests. The pathophysiology of ASD is not yet fully understood, due to a plethora of genetic and environmental risk factors that might be associated with or causal for ASD. Recent findings...

¹⁸²Tungsten Mössbauer spectroscopy of heteropolytungstates

Bochet, Christian G. ; Draper, Thérèse ; Bocquet, Bernard ; Pope, Michael T. ; Williams, Alan F.

In: Dalton Transaction, 2009, vol. 26, p. 5127-5131

The tungsten-182 Mössbauer spectra of a series of Keggin structure heteropolytungstates, [EW₁₂O₄₀]ⁿ⁻ are reported. There is a very considerable variation in quadrupole coupling at the tungsten nucleus indicating considerable asymmetry in the electron distribution for the more electronegative elements E. The quadrupole coupling correlates well with the structural data, in particular...

The 2003 heat wave as an example of summers in a greenhouse climate? Observations and climate model simulations for Basel, Switzerland

Beniston, Martin ; Diaz, Henry F.

In: Global and Planetary Change, 2004, vol. 44(1-4), p. 73

The heat wave that affected many parts of Europe during the course of summer 2003 may be a harbinger of summers that could occur more regularly in a future climate, under enhanced greenhouse gas concentrations. Switzerland was not exempt from the 2003 heat wave and, indeed, the previous absolute maximum temperature record dating back to the middle of the 20th century was exceeded by over 2 °C....
