X-FAST: A versatile, high-throughput, and user-friendly XUV femtosecond absorption spectroscopy tabletop instrument.

We present the X-FAST (XUV Femtosecond Absorption Spectroscopy Tabletop) instrument at the University of Wisconsin-Madison. The instrument produces femtosecond extreme ultraviolet photon pulses via high-harmonic generation in the range of 40-72 eV, as well as optical pump pulses for transient-absorption experiments. The system implements a gas-cooled sample cell that enables studying the dynamics of thermally sensitive thin-film samples.

Conversion of Organic Dyes into Pigments: Extraction of Flavonoids from Blackberries () and Stabilization.

The blackberry's color is composed mainly of natural dyes called anthocyanins. Their color is red-purple, and they can be used as a natural colorant. Anthocyanins are flavonoids, which are products of plants, and their colors range from orange and red to various shades of blue, purple and green, according to pH.

Economic freedom, pandemics, and robust political economy.

What is the relationship, if any, between economic freedom and pandemics? This paper addresses this question from a robust political economy approach. As is the case with recovery from natural disasters or warfare, a society that is relatively free economically offers economic actors greater flexibility to adapt to pandemics. We argue that societies that are more economically free will be more robust to the impact from pandemics, illustrated by shorter time for economic recovery.

Psychometric properties of the EQ-5D-5L in patients with major depression: factor analysis and Rasch analysis.

Background: The EQ-5D is one of the most recommended questionnaires for cost-effectiveness studies.

Aims: To study the psychometric properties of the EQ-5D-5L in patients with major depression.

Methods: This prospective observational study included 433 patients with major depression who completed the EQ-5D-5L and Patient Health Questionnaire-9 (PHQ-9) questionnaires at baseline, of whom 310 also did six months later.

A Review of the Phytochemistry, Traditional Uses and Biological Activities of the Essential Oils of Genus Teucrium.

The genus is a large and polymorphic genus of the Lamiaceae family distributed in mild climate zones, particularly in the Mediterranean basin and Central Asia. Studies of nonvolatile constituents of species showed that they are a rich source of -clerodane diterpenoids, considered as chemotaxonomic markers of the genus. In addition to the nonvolatile metabolites, there has been a large interest in the essential oils of this genus.
