Weak Crystallization of Fluctuating Skyrmion Textures in MnSi

Dirk Grundler

We report an experimental study of the emergence of nontrivial topological winding and long-range order across the paramagnetic-to-skyrmion lattice transition in the transition metal helimagnet MnSi. Combining measurements of the susceptibility with small- ...

Gold Raspberry-Like Colloidosomes Prepared at the Water-Nitromethane Interface

Hubert Girault, Pekka Eero Peljo, Evgeny Smirnov

Here, we propose a simple shake-flask method to produce micron-size colloidosomes from a liquid-liquid interface functionalized with a gold nanoparticle film. A step-by-step extraction process of an organic phase partially miscible with water led to the fo ...

Unified Theory for Recovery of Sparse Signals in a General Transform Domain

Kyong Hwan Jin

Compressed sensing is provided a data-acquisition paradigm for sparse signals. Remarkably, it has been shown that the practical algorithms provide robust recovery from noisy linear measurements acquired at a near optimal sampling rate. In many real-world a ...

Parallel Implementation Technique of Digital Equalizer for Ultra-High-Speed Wireline Receiver

Yusuf Leblebici, Alessandro Cevrero, Thomas Toifl, Lukas Kull, Ilter Ozkaya, Gain Kim, Cosimo Aprile

This paper presents a parallel implementation technique of digital equalizer for high-speed wireline serial link receiver (RX). In wireline RX, inter-symbol interference (ISI) is mitigated by continuous-time linear equalizer, and the remaining ISI is cance ...

Optimizing Image Denoising for Long-Range Brillouin Distributed Fiber Sensing

Luc Thévenaz, Marcelo Alfonso Soto Hernandez

Linear and nonlinear two-dimensional image processing approaches are analyzed with the aim of removing noise from data acquired by distributed optical fiber sensors based on Brillouin optical time-domain analysis (BOTDA). The impact of the filter parameter ...

Enantioselective Copper-Catalyzed Oxy-Alkynylation of Diazo Compounds

Jérôme Waser, Durga Prasada Rao Hari

Enantioselective catalytic methods allowing the addition of both a nucleophile and an electrophile onto diazo compounds give a fast access into important building blocks. Herein, we report the highly enantioselective oxyalkynylation of diazo compounds usin ...

UV and IR Spectroscopy of Cryogenically Cooled, Lanthanide-Containing Ions in the Gas Phase

Thomas Rizzo, Yoshiya Inokuchi

We measure UV and IR spectra in the gas phase for EuOH+, EuCl+, and TbO+ ions, which are produced by an electrospray ionization source and cooled to similar to 10 K in a cold, 22-pole ion trap. The UV photodissociation (UVPD) spectra of these ions show a n ...
