One simulation to have them all: performance of the Bias Assignment Method against N-body simulations

Cheng Zhao

In this paper, we demonstrate that the information encoded in one single (sufficiently large) N-body simulation can be used to reproduce arbitrary numbers of halo catalogues, using approximated realizations of dark matter density fields with different init ...

Combining ultra-high resolution ion-mobility spectrometry with cryogenic IR spectroscopy for the study of biomolecular ions

Thomas Rizzo, Ahmed Ben Faleh, Stephan Warnke, Robert Paul Pellegrinelli, Natalia Yalovenko

Double-resonance spectroscopic schemes in combination with cryogenic ion traps are the go-to techniques when isomer-specific high-resolution spectra are required for analysis of molecular ions. Their limitation lies in the requirement for well-resolved, is ...

Combining Ultrahigh-Resolution Ion-Mobility Spectrometry with Cryogenic Infrared Spectroscopy for the Analysis of Glycan Mixtures

Thomas Rizzo, Ahmed Ben Faleh, Stephan Warnke

The isomeric complexity of glycans make their analysis by traditional techniques particularly challenging. While the recent combination of ion mobility spectrometry (IMS) with cryogenic IR spectroscopy has demonstrated promise as a new tech-nique for glyca ...

Separation and Identification of Glycan Anomers Using Ultrahigh-Resolution Ion Mobility Spectrometry and Cryogenic Ion Spectroscopy

Thomas Rizzo, Ahmed Ben Faleh, Stephan Warnke, Valeriu Scutelnic

The analysis of carbohydrates, or glycans, is challenging for established structure-sensitive gas-phase methods. The multitude of possible stereo-, regio- and structural isomers make them substantially more complex to ana-lyze than DNA or proteins, and no ...

Quantification of THC in Cannabis plants by fast-HPLC-DAD: A promising method for routine analyses

Christophe Roussel, Céline Burnier

Nowadays, Gas Chromatography Mass Spectrometry (GC-MS) is mainly used in forensic sciences but suffers from limitations when the analysed compounds are thermally instable as it is the case for THC-A (Tetrahydrocannabinolic Acid) which is converted into Del ...

A method for improvement of mass resolution and isotope accuracy for laser ablation time-of-flight mass spectrometers

Reto Wiesendanger, Peter Wurz

Accumulation of spectra is a common approach for improvement of the signal-to-noise ratio (SNR) in mass spectrometry. However, severe degradation of the overall spectrum can occur if some individual mass spectra, affected by peak broadening, are included i ...

The pro-apoptotic effect of a Terpene-rich Annona cherimola leaf extract on leukemic cell lines

Rita Sarkis, Maria Younes

Background The edible fruit Annona cherimola has previously shown many nutritional and medicinal properties. The current study evaluates the anti-cancer and anti-proliferative properties of Annona cherimola ethanolic leaf extract (AELE) on Acute Myeloid Le ...

Impact of the Oxygen Content on the Optoelectronic Properties of the Indium-Tin-Oxide Based Transparent Electrodes for Silicon Heterojunction Solar Cells

Christophe Ballif, Mathieu Gérard Boccard, Jan Haschke, Jean Cattin, Brahim Aissa, Akshath Raghu Shetty

Amorphous/crystalline silicon heterojunction (SHJ) solar cells technology is attracting tremendous attention in recent years due to its potential to achieve high power conversion efficiencies at low fabrication temperatures and using few process steps. How ...

Cold ion spectroscopy for structural identifications of biomolecules

Oleg Boyarkine

Over the last decade, the spectroscopy of cryogenically cold ions iso- lated in the gas phase has been developed as a new tool for structural elucidations of biological molecules. Cooling allows for vibrational resolution in UV and IR spectra of small to m ...
