Charlotte Pommer: Resistance fighter and female pioneer of German anatomy

Anatomical Sciences Education, EarlyView.
Abstract This article examines the biography and unique case of Charlotte Pommer (1914–2004), the only anatomist documented to have left the field during the Nazi period after encountering the regime's victims on the dissection table. While she is known for her resistance activities, newly presented documentation reveals her role as the provisional ...

Dynamics of biotic resistance to plant invasions

Biological Reviews, EarlyView.
ABSTRACT Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long‐term dynamics of biological invasions. A large body of empirical research on biotic resistance has accumulated since the last comprehensive review on the subject 20 years ago, enabling us to achieve a refined understanding of ...

Routes to Cyclobutadiene and Cycloallyl Pt(II) Complexes: Dicationic Bis(Alkyne) Species as Intermediates

Chemistry – A European Journal, EarlyView.
This work demonstrates the synthesis of cationic Pt(II) η3‐cycloallyl complexes, and experimental and computational studies show a ligand bite‐angle dependence of their formation rates. The reactivity of these complexes with Brønsted acids was investigated, leading to the formation of cationic and dicationic Pt(II) η4‐cyclobutadiene complexes ...

SUPER and femtosecond spin-conserving coherent excitation of a tin-vacancy color center in diamond

Nature Communications
The coherent excitation of an optically active spin system is one of the key elements in the engineering of a spin-photon interface. Using the novel SUPER scheme, we coherently control the main optical transition of a tin-vacancy color center in diamond ...

Diminished heart beat nonstationarities in congestive heart failure

Frontiers in Physiology, 2013
Studies on heart rate variability (HRV) have become popular and the possibility of diagnosis based on non-invasive techniques compels us to overcome the difficulties originated on the environmental changes that canaffect the signal.

Multi‐state Photoswitching in Thienoquinoid‐Based Fluorescent Trithiophenes

Chemistry – A European Journal, EarlyView.
A methine‐bridged trithiophene with a thienoquinoid core undergoes photoisomerization of both C═C bonds, affording three geometrical isomers in a ratio controlled by the irradiation wavelength. Despite full π‐conjugation, the system retains fluorescence, enabling wavelength‐addressable multi‐state switching with luminescent readout.

Dioxygen Reduction at a Cu(I) Complex Supported by a Macrocyclic N3O Ligand System

Chemistry – A European Journal, EarlyView.
A non‐reactive [CuI(14‐TMC)]+ complex is transformed to an efficient catalyst [CuI(14‐TMCO)]+ (TMCO = 4,8,12‐trimethyl‐1‐oxa‐4,8,12‐triazacyclotetradecane) for 4e−/4H+ reduction of O2 by N → O substitution. ABSTRACT CuI(14 TMCO) (1), involving a N3O‐macrocycle, reacts with O2 at cryogenic temperatures to yield an end‐on peroxodicopper(II) species.
