Calibration in Temperature of Photometric Parameters [PDF]

Symposium - International Astronomical Union, 1985
It is very easy to use a Planck distribution to show that a color index is a temperature parameter, but it is more difficult to calibrate such a color index in terms of temperature because only a few Teff values are determined. A pioneering work is that of Kuiper (1938), who derived a temperature scale according to spectral type (from A0 to M2 for ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

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 ...

Intelligent Identification of Dominant Error-Causing Parameters for Dynamic Simulation Models of Power Systems Based on Time–Frequency Feature Learning of Response Errors

EAI Endorsed Transactions on Energy Web
INTRODUCTION: Dynamic simulation is important for disturbance analysis and security assessment in power systems. Parameter deviations can cause discrepancies between simulated and measured responses, and multiple deviations may produce complex transient ...

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

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.

Development and Application of External Moving Type Calibration Device for Beam Detector Based on Quasi-impedance Matching Transmission

Yuanzineng kexue jishu, 2022
The beam calibration results are affected by the impedance of the calibration device. If impedance matching is not maintained, reflected signals would be generated, which would lead to the superposition of reflected signals and excitation signals ...

Robust multi-objective calibration strategies – possibilities for improving flood forecasting [PDF]

Hydrology and Earth System Sciences, 2012
Process-oriented rainfall-runoff models are designed to approximate the complex hydrologic processes within a specific catchment and in particular to simulate the discharge at the catchment outlet. Most of these models exhibit a high degree of complexity

Parameter-induced uncertainty quantification of soil N₂O, NO and CO₂ emission from Höglwald spruce forest (Germany) using the LandscapeDNDC model [PDF]

, 2012
Assessing the uncertainties of simulation results of ecological models is becoming increasingly important, specifically if these models are used to estimate greenhouse gas emissions on site to regional/national levels. Four general sources of uncertainty

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Calibration Method of PFC3D Micro-Parameters under Impact Load

Applied Sciences
Micro-parameter calibration is essential in constructing an accurate and reliable numerical model of particle discrete element PFC3D 6.0 software. Micro-parameter calibration is mainly accomplished according to the macro-parameters obtained from static ...
