Mitochondrial DNA mutations in RRF of healthy subjects of different age

Neurobiology of Aging, 2005
To obtain information on the mechanisms responsible of the generation of ragged red fibers (RRF) during aging, we analyzed the mitochondrial genotype of single skeletal muscle fibers of healthy individuals having an age comprised between 45 and 92 years.

RRF: A Race Reproduction Framework for Use in Debugging Process-Level Races

2016 IEEE 27th International Symposium on Software Reliability Engineering (ISSRE), 2016
Process-level races are endemic in modern systems. These races are difficult to debug because they are sensitive to execution events such as interrupts and scheduling. Unless a process interleaving that can result in the race can be found, it cannot be reproduced and cannot be corrected.

X-ray Structural Studies of Mycobacterium tuberculosis RRF and a Comparative Study of RRFs of Known Structure. Molecular Plasticity and Biological Implications

Journal of Molecular Biology, 2005
The crystal structure of Mycobacterium tuberculosis ribosome recycling factor has been determined and refined against three X-ray diffraction data sets, two collected at room temperature and the other at 100K. The two room-temperature data sets differ in the radiation damage suffered by the crystals before the data used for processing were collected. A

Governing the RRF

2023
The National Recovery and Resilience Plans represent the new framework in which European member states identify their development strategies and allocate European and national resources – with the objective of relaunching socio-economic conditions following the coronavirus pandemic. This process, initiated as part of the European response to the global

Robust event detection by radial reach filter (RRF)

Object recognition supported by user interaction for service robots, 2003
We propose a novel statistical measure for robust event detection, called 'Radial Reach filter' (RRF). The capability of detecting new objects (events) from a time-series image is an important problem of vision systems. The usual method of detecting new objects is simple background subtraction, that is to subtract current image from a background image.

Mitigation Efforts to Address Rapid Refresh Forecast System (RRFS) v1 Dynamical Core Performance Issues and Recommendations for RRFS v2

2023
The RRFS is being developed as the flagship convective-scale ensemble-based prediction system for NWS operations to replace legacy limited-area modeling systems currently in operations in early calendar year 2025. The RRFS is an application based on the Unified Forecast System (UFS) and, like other UFS-based applications, uses the FV3 dynamical core.

Structure of the chloroplast ribosome with chl-RRF and hibernation-promoting factor

Nature Plants, 2018
Oxygenic photosynthesis produces oxygen and builds a variety of organic compounds, changing the chemistry of the air, the sea and fuelling the food chain on our planet. The photochemical reactions underpinning this process in plants take place in the chloroplast.

Robust object detection using a Radial Reach Filter (RRF)

Systems and Computers in Japan, 2004
AbstractIn this paper the authors report on a new algorithm used to separate an object from its background using a background image. In the past, simple background subtraction has been used because of its low processing costs and ease of implementation. However, because this method depends solely on brightness patterns in the object and shadows, it has

Conformational activation of ribosome recycling by intra- and inter-molecular dynamics of RRF

International Journal of Biological Macromolecules, 2020
Ribosome recycling is the final step of the cyclic process of translation, where the post-termination complex (PoTC) is disassembled by the concerted action of ribosome recycling factor (RRF) and elongation factor G (EF-G) in the sub-second time range.

RRF: A Double-Layer Reputation Mechanism with Rating Reputation Considered

2006
As reputation mechanism has been widely accepted and adopted to enhance trust in electronic communities, how to cope with the attack and disturbance problems on reputation mechanism, such as collusion, malicious or unfair rating, becomes a key challenge.
