Astronomical Spectroscopy

, 2011
Spectroscopy is one of the most important tools that an astronomer has for studying the universe. This chapter begins by discussing the basics, including the different types of optical spectrographs, with extension to the ultraviolet and the near ...

Recognizing early MRI signs (or their absence) is crucial in diagnosing metachromatic leukodystrophy

Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1999-2009, December 2022., 2022
Abstract Objectives Metachromatic leukodystrophy (MLD) has characteristic white matter (WM) changes on brain MRI, which often trigger biochemical and genetic confirmation of the diagnosis. In early or pre‐symptomatic disease stages, these typical MRI changes might be absent, hampering early diagnosis.

Dark Spectroscopy

, 2017
Rich and complex dark sectors are abundant in particle physics theories. Here we propose performing spectroscopy of the mass structure of dark sectors via mono-photon searches at lepton colliders.

Optical inter-site spin transfer probed by energy and spin-resolved transient absorption spectroscopy

Nature Communications, 2020
Optically driven spin transfer is the fastest process to manipulate magnetism. Here, the authors show that this process emerges as the dominant mechanism in femtosecond spin dynamics enabling to the engineering of functional magnetic systems for future ...

New Hadronic Spectroscopy [PDF]

Riv. Nuovo Cim. 033:633-712,2010, 2010
In the past few years the field of hadron spectroscopy has seen renewed interest due to the pubblication, initially mostly from B-Factories, of evidences of states that do not match regular spectroscopy, but are rather candidates for bound states with additional quarks or gluons.

Tetraquark spectroscopy

, 2006
A complete classification of tetraquark states in terms of the spin-flavor, color and spatial degrees of freedom was constructed. The permutational symmetry properties of both the spin-flavor and orbital parts of the quark-quark and antiquark-antiquark ...

Unified picture of vibrational relaxation of OH stretch at the air/water interface

Nature Communications
The elucidation of the energy dissipation process is crucial for understanding various phenomena occurring in nature. Yet, the vibrational relaxation and its timescale at the water interface, where the hydrogen-bonding network is truncated, are not well ...

Bottomonium(-like) State Spectroscopy at B-Factories [PDF]

, 2013
Bottomonium spectroscopy is a key source necessary for understanding of Quantum Chromodynamics. The expected results of this endeavor will provide important tests for various theoretical approaches to understanding quark-antiquark interaction dynamics. Recent results in bottomonium spectroscopy are presented.
