A constrained pseudo random function (PRF) behaves like a standard PRF, but with the added feature that the (master) secret key holder, having secret key K, can produce a constrained key, K{f}, that allows for the evaluation of the PRF on all inputs satisfied by the constraint f . Most existing constrained PRF constructions can handle only bounded length inputs. In a recent work, Abusalah et al...

OBJECTIVE The aim of this study was to evaluate effect of pulsed radiofrequency (PRF) neuromodulation of suprascpaular nerve (SSN) in patients with chronic shoulder pain due to adhesive capsulitis and/or rotator cuff tear. METHODS The study included 11 patients suffering from chronic shoulder pain for at least 6 months who were diagnosed with adhesive capsulitis (n=4), rotator cuff tear (n=5)...

Introduction: Gingival recession defects in the esthetic zone demands a concurrent correction of all involved teeth single surgery. Wound healing is complex phenomenon and use collagen membrane Injectable Platelet rich fibrin (I-PRF) will greatly enhance process. Thus aim this case report to evaluate effectiveness Coronally advanced flap (CAF) with I-PRF management gingival management. There wa...

We define a new black-box property for cryptographic hash function families H : {0, 1}×{0, 1}∗ → {0, 1} which guarantees that for a randomly chosen hash function HK from the family, everything “non-trivial” we are able to compute having access to the key K, we can compute only with oracle access to HK . If a hash function family is pseudo-random and has the black-box property then a randomly ch...

In sinus floor augmentation of an atrophic posterior maxilla, platelet-rich fibrin (PRF) has been used as a graft material. We herein report two cases with histological evaluations of PRF after the surgery. The first case was a 28-year-old female with an atrophic right posterior maxilla who was treated with sinus floor augmentation and simultaneous implant placement using PRF as the sole graft ...

$\ensuremath{-}1$ programmed ribosomal frameshifting ($\ensuremath{-}1\text{ }\text{ }\mathrm{PRF}$) is stimulated by structures in messenger RNA (mRNA), but the factors determining $\ensuremath{-}1\text{ }\mathrm{PRF}$ efficiency are unclear. We show that varies directly with conformational heterogeneity of stimulatory structure, quantified as Shannon entropy state occupancy, for a panel effic...

More insight into the biological fundamentals of leukocyte platelet-rich fibrin (L-PRF) guided healing is necessary to recommend its application, in particular in deficient bone sites that need to support implants. This study investigated the short-term bone healing effect of L-PRF treatment in cylindrical non-critical sized bone defects with 3 mm diameter and 6 mm depth in tibiae of 18 adult m...

We propose a structure cognizant framework for pseudo relevance feedback (PRF). This has an application, for example, in selecting expansion terms for general search from subsets such as Wikipedia, wherein documents typically have a minimally fixed set of fields, viz., Title, Body, Infobox and Categories. In existing approaches to PRF based expansion, weights of expansion terms do not depend on...

Introduction: Gold standard for alveolar cleft bone grafting is autogenous bone. Advantage of adding the growth factors to the bone is established, so adding PRF to the autogenous bone may have beneficial effects. Methods:  Platelet-rich plasma admixed with autogenous bone and as a biologic membrane over the bone grafted alveolar cleft was used. Results:  Autogenous bone in all (four cases...
