Quantum Security of the Legendre PRF.

IACR Cryptol. ePrint Arch., 2021
In this paper, we study the security of the Legendre PRF against quantum attackers, given classical queries only, and without quantum random-access memories. We give two algorithms that recover the key of a shifted Legendre symbol with unknown shift, with a complexity smaller than the exhaustive search of the key.

Management of severe bone loss in patients at risk of medication‐related osteonecrosis of the jaw with microsurgery and guided bone regeneration: A case study

Clinical Advances in Periodontics, EarlyView.
Abstract Background Medication‐related osteonecrosis of the jaw (MRONJ) is a challenging complication associated with antiresorptive medications. Its exact pathophysiology remains unclear, but dental extractions and infections are known triggers, complicating prevention, and treatment.

Five‐year tomographic and clinical evaluation of the socket shield technique: Case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background The socket shield technique, one modality of partial extraction therapy, aims to preserve periodontal tissues and maintain the buccal alveolar bone volume following immediate implant placement or in prosthetic pontic sites, by the strategic maintenance of a tooth root fragment.

Comparative Study of Gas and Liquid Flow in Packed Beds Using Phase‐Contrast MRI

Chemie Ingenieur Technik, EarlyView.
This work presents applications of phase‐contrast magnetic resonance imaging (MRI) to investigate fluid flow fields and temperature in packed beds. Comparison of ethane (C2H6) gas flow with that of water flow is done at similar flow conditions. The temperature of water is also measured using MRI.

Application of i-PRF in dentistry

Wiadomości Lekarskie
Injectable platelet-rich fibrin (i-PRF) is a novel platelet concentrate that has been employed in dentistry with the objective of promoting tissue regeneration and healing. In contrast to platelet-rich plasma (PRP), i-PRF is more straightforward to handle, more cost-effective, and free from anticoagulants, which reduces biochemical alterations.

Development and preclinical evaluation of a hybrid stereoelectroencephalographic–laser depth electrode for magnetic resonance imaging‐guided interstitial thermal therapy in drug‐resistant epilepsy

Epilepsia, EarlyView.
Abstract Objective This study was undertaken to design and validate a hybrid depth electrode combining stereoelectroencephalographic (sEEG) recording and magnetic resonance‐guided laser interstitial thermal therapy (MRgLITT) under real‐time magnetic resonance thermometry, to streamline the transition from invasive localization to focal ablation in ...

A Numerical Investigation of the Effects of Piston Bowl Geometry and Spray Angle on Combustion, Performance and Emission of a Diesel Engine

Energy Science &Engineering, EarlyView.
A piston bowl's design and spray angle improve air‐fuel mixing, resulting in more complete combustion and higher efficiency. Ansys Forte 2023 R1 a CFD software was used to analyze the effects of five combustion chamber geometries of cylinder, modified re‐entrant, re‐entrant, double‐stepped, and stepped on engine performance, combustion, and emission ...

Platelet-Rich fibrin (PRF) and its application in dentistry: A literature review

Journal of Pharmacy and Bioallied Sciences
Platelet-rich fibrin (PRF) is a biocompatible fibrin matrix that acts as a resorbable membrane, collecting platelet cytokines, growth factors, and cells and releasing them. It is easily extracted from blood.
