Referenceless PRF shift thermometry [PDF]
Magnetic Resonance in Medicine, 2004 AbstractThe proton resonance frequency (PRF) shift provides a means of measuring temperature changes during minimally invasive thermotherapy. However, conventional PRF thermometry relies on the subtraction of baseline images, which makes it sensitive to tissue motion and frequency drift during the course of treatment.

The effect of omental pedicle flap with platelets-rich fibrin on reconstruction of induced-urinary bladder defect in dogs [PDF]
Iraqi Journal of Veterinary SciencesThe research was planned to evaluate the ability of an omental pedicle flap with platelets-rich fibrin (PRF) to augment bladder defects in dogs. Eighteen adult- male dogs were used.

The Sum of PRPs Is a Secure PRF [PDF]
, 2000 Given d independent pseudorandom permutations (PRPs) πi, ..., πd over {0; 1}n, it appears natural to define a pseudorandom function (PRF) by adding (or XORing) the permutation results: sumd(x) = π1(x) ⊕...⊕πd(x). This paper investigates the security of sumd and also considers a variant that only uses one single PRP over {0; 1}n.

Polymers, 2022 Predictable outcomes intended by the application of PRF (platelet-rich fibrin) derivative membranes have created a lack of consideration for their consistency and functional integrity. This study aimed to compare the mechanical properties through tensile strength and analyze the structural organization among the membranes produced by L-PRF (leukocyte ...

Adaptive Security of Constrained PRFs [PDF]
, 2014 Constrained pseudorandom functions have recently been introduced independently by Boneh and Waters (Asiacrypt’13), Kiayias et al. (CCS’13), and Boyle et al. (PKC’14). In a standard pseudorandom function (PRF) a key k is used to evaluate the PRF on all inputs in the domain.

Advanced Engineering Materials, EarlyView.The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...

Key Homomorphic PRFs and Their Applications [PDF]
, 2013 A pseudorandom function \(F: {\mathcal K} \times{\mathcal X} \to{\mathcal Y}\) is said to be key homomorphic if given F(k1,x) and F(k2,x) there is an efficient algorithm to compute F(k1 ⊕ k2, x), where ⊕ denotes a group operation on k1 and k2 such as xor.

Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring
Advanced Functional Materials, EarlyView.This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.
