Performance of a Prototype MR-TOF-MS for the LEB of the Super-FRS

A multiple-reflection time-of-flight mass spectrometer (MR-TOF-MS) [1] will be an important part of the MATS/LaSpec beam-line at the Low-Energy-Branch (LEB) of the Super-FRS at FAIR. The MR-TOF-MS is a fast (∼ms), multi-purpose, non-scanning mass spectrometer with single-ion sensitivity and will be used as a broadband mass spectrometer, as isobar separator or for direct mass measurements of ver...

A novel FRS Data Acquisition

In the experiments involving the use of in-flight radioactive beams the selectivity and the detection of the rare products are very demanding. Using faster processing and data acquisition (DAQ) is also important and can be crucial for the realization of those experiments that otherwise may require a non realistic beam time. In particular, here we concern with experiments which can be performed ...

Objectives: The aims of this study were to: (1) determine the prevalence of undernutrition and frailty in hospitalised elderly patients and (2) evaluate the efficacy of both the Mini-Nutritional Assessment (MNA) screening tool and the MNA short form (MNA-SF) in identifying frailty. Setting and Participants: A convenient sample of 100 consecutive patients (75.0 % female) admitted to the Geriatri...

The Fractional Chapman Kolmogorov Equation

The Chapman–Kolmogorov equation with fractional integrals is derived. An integral of fractional order is considered as an approximation of the integral on fractal. Fractional integrals can be used to describe the fractal media. Using fractional integrals, the fractional generalization of the Chapman–Kolmogorov equation is obtained. From the fractional Chapman–Kolmogorov equation, the Fokker–Pla...
