The Halos and Environments of Nearby Galaxies (HERON) survey IV. Complexity in the boxy galaxies NGC720 and NGC2768

The shapes of galaxies, their outer regions in particular, are important guideposts to their formation and evolution. In this work, we report on the discovery of strongly box-shaped morphologies of the otherwise well-studied elliptical and lenticular galax ...

Transfer learning application of self-supervised learning in ARPES

Gabriel Aeppli

There is a growing recognition that electronic band structure is a local property of materials and devices, and there is steep growth in capabilities to collect the relevant data. New photon sources, from small-laboratory-based lasers to free electron lase ...

Demography of galactic technosignatures

Claudio Grimaldi

Probabilistic arguments about the existence of technological life beyond Earth traditionally refer to the Drake equation to draw possible estimates of the number of technologically advanced civilizations releasing, either intentionally or not, electromagne ...

Thermorefractive noise in silicon-nitride microresonators

Tobias Kippenberg, Junqiu Liu, Erwan Guillaume Albert Lucas, Arslan Sajid Raja, Nils Johan Engelsen, Guanhao Huang

Thermodynamic noise places a fundamental limit on the frequency stability of dielectric optical resonators. Here, we present the characterization of thermorefractive noise in photonic-chip-based silicon-nitride (Si3N4) microresonators and show that thermor ...

Tesla: An application for real-time data analysis in High Energy Physics

Ilya Komarov, Gerhard Raven

Upgrades to the LHCb computing infrastructure in the first long shutdown of the LHC have allowed for high quality decay information to be calculated by the software trigger making a separate offline event reconstruction unnecessary. Furthermore, the storag ...

Impact of tunneling anisotropy on the conductivity of nanorod dispersions

Claudio Grimaldi, Biagio Nigro

While the tunneling conductance between two spherical-like conducting particles depends on the relative interparticle distance, the wave function overlap between states of two rodlike particles, and so the tunneling conductance, depends also on the relativ ...

Search for Bottomonium States in Exclusive Radiative gamma(2S) Decays

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Jun Yong Kim, Ji Hyun Kim, Donghyun Kim, Dipanwita Dutta, Xiao Wang

We search for bottomonium states in gamma(2S) -> (b (b) over bar)gamma decays with an integrated luminosity of 24.7 fb(-1) recorded at the gamma(2S) resonance with the Belle detector at KEK, containing (157.8 +/- 3.6) x 10(6) gamma(2S) events. The (b (b) o ...

HILBERT TRANSFORM RELATIONS IN FREQUENCY-DOMAIN OPTICAL-COHERENCE TOMOGRAPHIC IMAGING

Theo Lasser, Chandra Sekhar Seelamantula

Interferometric imaging techniques typically embed the object phase information in the magnitude during the measurement process. During reconstruction, the phase is recovered from the magnitude by certain approximations on the measured magnitude and underl ...

Dictionary Identification - Sparse Matrix-Factorisation via $\ell_1$-Minimisation

Karin Schnass, Rémi Gribonval

This article treats the problem of learning a dictionary providing sparse representations for a given signal class, via

\ell_1

-minimisation. The problem can also be seen as factorising a

\ddim \times \nsig

matrix $Y=(y_1 \ldots y_\nsig), , y_n\in \R^\ ...

Stability properties of anisotropic pressure stellarator plasmas with fluid and noninteractive energetic particles

Wilfred Anthony Cooper, Jonathan Graves, Trach-Minh Tran

The three-dimensional (3-D) VMEC code has been modified to model an energetic species with a variant of a Bi-Maxwellian distribution function that satisfies the constraint B . del F-h = 0, and the 3-D TERPSICHORE stability code has been extended to investi ...
