Few-cycle pulse retrieval using amplitude swing technique.

Ultrashort pulses have garnered significant attention across various scientific disciplines and applications. In this paper, we demonstrate that the recently introduced amplitude swing technique is a robust method for characterizing pulses in the few-cycle temporal domain by analyzing compressed and chirped pulses from a Ti:Sapphire laser oscillator. The duration of the measured pulse for the case of best compression was 5.

Experiencing beauty in everyday life.

Beauty surrounds us in many ways every day. In three experience sampling (ESM) studies we investigated frequency, category of eliciting stimuli (natural vs human-made) and, the potential moderating role of several individual difference measures on such everyday experiences of beauty in an ecologically valid manner. Further, we explored the impact of such experiences on valence & arousal.

Towards the Standardization of Photothermal Measurements of Iron Oxide Nanoparticles in Two Biological Windows.

A systematic study on laser-induced heating carried out in two biological windows (800 nm and 1053 nm) for FeO nanoparticles in water suspension showed evidence of the strong dependence of the specific absorption rate (SAR) on extrinsic parameters such as the vessel volume or laser spot size. The results show that a minimum of 100 μL must be used in order to obtain vessel-size-independent SARs. In addition, at a constant intensity but different laser powers and spot size ratios, the SARs can differ by a three-fold factor, showing that the laser power and irradiated area strongly affect the heating curves for both wavelengths.

Does self-reported chronic pain influence savoring of aesthetic experiences?

Background: Aesthetic experiences elicit a wide range of positive emotions and have a positive impact on various health outcomes. In this context, savoring refers to a cognitive form of emotion regulation used to maintain and extend positive emotional experiences and is considered to contribute to health and well-being. Chronic pain has been linked to reduced reward-seeking behavior.
