Injectable platelet‐rich fibrin (I‐PRF) is a second generation, fully autologous, blood‐derived biomaterial having three‐dimensional fibrin meshwork, like that of a PRF clot, while retaining the fluid nature, just like platelet‐rich plasma (PRP).

Guided bone regeneration (GBR) is a process that involves the regeneration of bone defects through the application of occlusive membranes that mechanically exclude the population of non-osteogenic cells from the surrounding soft tissue.

On the Query Complexity of Constructing PRFs from Non-adaptive PRFs
2020This paper studies constructions of pseudorandom functions (PRFs) from non-adaptive PRFs (naPRFs), i.e., PRFs which are secure only against distinguishers issuing all of their queries at once.

Рассмотрены показания, противопоказания, методика получения и применение обогащѐнного тромбоцитами фибрина (PRF). Обогащѐнный тромбоцитами фибрин используется для улучшения процесса заживления костной ткани и слизистых оболочек в ходе выполнения стоматологических манипуляций, в частности при синус-лифтинге, в мукогингивальной хирургии, при лечении ...

Population receptive field (pRF) modelling project. We used wedge-shaped stimuli to map the visual cortex (V1, V2, V3, V3A, V4) in healthy adults. We used mapping sequences of different duration and different spatio-temporal properties (ordered, predictable, random) to address the impact of sequence order and stimulus predictability in pRF properties.

In this chapter, we will take a closer look at medium PRF operation. We will see what must be done to separate targets from clutter and how the signal processing is performed. We will then take up the problems of rejecting ground moving targets, eliminating blind zones, minimizing sidelobe clutter, and rejecting sidelobe return from those targets on ...

18th International Conference on Infrared and Millimeter Waves, 1993
Details are presented of the Strathclyde University Cyclotron Autoresonance Maser (CARM) experiment. Thespecification and device characteristics will be reported for CARM oscillation in the 12-20 GHz band. In contrastto previously reported CARM devices1'2, pulse repetition frequencies (PRF) greater than 100 Hz have beenemployed.

At low PRF, mainlobe clutter may largely be eliminated by offsetting the Doppler spectrum so the central line is at dc and passing the return through a clutter canceller and bank of Doppler filters. To keep the clutter in the canceller's rejection notches, the 'offset' must be varied with radar speed and antenna look angle.

Detection range, of course, increases with the ratio of the signal energy to the energy of the background noise and clutter. By employing a high duty factor, high PRF waveform, therefore, long detection ranges can be obtained against nose-aspect targets even in a clutter environment.

Vermehrte Belichtungsanforderungen mit natur – lichem Licht und eine Verbesserung der Raumbezuge zwischen Innenraumen und Ausenbereichen fuhren bei Gebauden zunehmend zu Vergroserungen der Fensterflachenanteile innerhalb der Fassaden (s. a. Abschnitt 9 in Teil 1 dieses Werkes).
