Multiwavelength highly transient stimulated Raman scattering on dual Raman modes in Sr(MoO)(WO) and Sr(MoO)(WO).

For the first time to our knowledge, multiwavelength, highly transient, single-pass stimulated Raman scattering with a low wavelength spacing on dual (stretching and bending) Raman modes in Sr(MoO)(WO) and Sr(MoO)(WO) solid solutions in a range of 1000-1300 nm (transparence window of biological tissue) under ultrafast chirped pulse laser pumping is comparatively investigated in the interests of multicolor two-photon imaging of a living tissue. For both the solid solutions, the optimum range (1-5 ps) of chirped pump pulse durations for multiwavelength Raman conversion on dual Raman modes was wider than for SrMoO (2-3 ps) due to the higher integral cross section of the bending Raman mode. Higher efficient SRS conversion took place at negative chirping of the pump pulse with its stretching from 0.

Laser induced damage threshold of GaSe with antireflection microstructures at a wavelength of 5 µm.

Large GaSe crystals were grown and various antireflection microstructures (ARMs) were fabricated on their cleaved surfaces using optimized femtosecond laser ablation, which provided the antireflection effect in a wide wavelength range of 4-16 µm. The influence of ARMs created on the GaSe surface on the change of the laser-induced damage threshold (LIDT) of the crystal at a wavelength of 5 μm was evaluated. The 5-µm Fe:ZnMgSe laser with the pulse duration of 135 ns was used for the LIDT test in conditions close to single pulse exposure.

[Relationship between the pain severity, use of non-steroidal anti-inflammatory drugs and blood pressure in elective large joint arthroplasty of the lower extremities].

Aim: To evaluate the changes in blood pressure (BP), the severity of pain syndrome and non-steroidal anti-inflammatory drugs (NSAIDs) use patterns in patients hospitalized for elective arthroplasty of large joints of the lower extremities during the postoperative period.

Materials And Methods: This study included 374 patients. In all patients, medical history, antihypertensive therapy and history of NSAIDs usage were collected, BP was measured, and the severity of pain was assessed via a 10-point scale before surgery, as well as 1 and 3 months after arthroplasty.

Highly transient stimulated Raman scattering in SrMoO under ultrafast laser pumping with a controllable chirp.

For the first time, to the best of our knowledge, we demonstrate highly transient, multiwavelength, single-pass Raman generation with combined frequency shifts on two Raman modes of an SrMoO crystal with high total Raman conversion efficiency of up to 48% in conditions of competition with self-phase modulation (SPM). A 58-mm-long SrMoO crystal was used as the active medium under pumping by the 1030-nm, 40-µJ laser pulses with controllable dispersive stretching in a range of 0.25-6 ps at negative and positive chirping.

The voice of Twitter: observable subjective well-being inferred from tweets in Russian.

As one of the major platforms of communication, social networks have become a valuable source of opinions and emotions. Considering that sharing of emotions offline and online is quite similar, historical posts from social networks seem to be a valuable source of data for measuring observable subjective well-being (OSWB). In this study, we calculated OSWB indices for the Russian-speaking segment of Twitter using the Affective Social Data Model for Socio-Technical Interactions.
