FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Exposure Time Variation Method Using DMD for Microstereolithography
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2012 In stereolithography, parts are fabricated by curing photopolymeric resins with light. The application of stereolithography can now be extended to a very small scale. The process, called microstereolithography, can fabricate parts on a microscale without

Dynamic Correction of the Influence of Long Measuring Path Irregularity in Antenna Tests
Applied Sciences, 2021 This article investigates the influence of random microwave discontinuities on the characteristics of long transmission paths. This is most important for dynamic measuring stands, accompanied by multiple space movement of long transmission paths with ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

The modern method of creating dynamically scaled models to study aircraft flutter characteristics
Учёные записки Казанского университета: Серия Физико-математические науки, 2020 A complex research, which included the design, manufacture, and testing of a dynamically scaled model of the all-moving tail (AMT) of an aircraft with the numerical calculations at each stage, was carried out. The dynamically scaled model was designed to

Cavity shape and beam dynamics design for a linac for pions [PDF]
Conference Record of the 1991 IEEE Particle Accelerator Conference, 2002 A linac to accelerate pions from 400 to 920 MeV kinetic energy is being designed as an upgrade to the LAMPF accelerator facility at Los Alamos, New Mexico. Calculations for the design of the superconducting cavity shape attempt to reduce the peak surface field needed to achieve a given accelerating gradient, yet ensure sufficient cell-to-cell coupling ...

Preliminary Results on Beam Dynamics of Laser Pulse Shaping Effects in SPARC [PDF]
Proceedings of the 2005 Particle Accelerator Conference, 2006 Electron beams with different initial pulse characteristics have been transported along the SPARC photoinjector. The differences we considered come from the possible profiles of the laser pulse driving the radiofrequency (rf) electron gun. Realistic deviations from the ideal flat-top pulse give for example a ramp or multi-peaks shape with a relative ...

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments
FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...
