The Sum of PRPs Is a Secure PRF [PDF]

open access: yes, 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.

Straight sesamoidean ligament desmopathy commonly occurs with proximal interphalangeal joint osteoarthritis

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Proximal interphalangeal joint osteoarthritis (PIPJ OA) is a common cause of poor performance in the equine athlete; however, the supporting soft tissue structures surrounding the joint are seldom evaluated. Straight sesamoidean ligament injuries have been previously hypothesised to be concomitant with PIPJ OA; however, the ...

Heterogeneous Exhumation Mechanisms in Neoproterozoic Collisional Metamorphism: P–T Constraints From Pelotas and Punta del Este Terranes, Southern Brazil and Uruguay

open access: yesGeological Journal, EarlyView.
Petrography, thermobarometry, and pseudosection modelling reveal peak metamorphic conditions of 3–7.5 kbar and 520°C–800°C in Tonian‐Cryogenian orthogneisses of the Dom Feliciano Belt. Metamorphic field gradients of 27°C/km–39°C/km and variable exhumation mechanisms support correlation of these units as remnants of a Himalayan‐type Piratini Orogeny ...

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

Hematological and Genotoxic Effects of Subchronic Oral Exposure to a Mancozeb‐Based Fungicide in Female Mice

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT The extensive use of pesticides in modern agriculture has raised increasing concerns regarding the potential biological effects of repeated exposure to pesticide residues and commercial formulations. Mancozeb is a widely used ethylene‐bis‐dithiocarbamate fungicide; however, information on its hematological and genotoxic effects following ...

Tales From Within: Dental Students’ Reflective Activities Involving Equity‐Deserving Communities

open access: yesJournal of Dental Education, EarlyView.
ABSTRACT Objective Undergraduate dental training benefits from community service‐learning (CSL) placements, in which equity‐deserving groups receive oral health care and students can critically reflect on their experiences. This study aimed to thematically explore the moments of revelation and struggle that senior dental students reflected on while ...

The prion protein gene:a role in mouse embryogenesis? [PDF]

open access: yes, 1992
The neural membrane glycoprotein PrP (prion protein) has a key role in the development of scrapie and related neurodegenerative diseases. During pathogenesis, PrP accumulates in and around cells of the brain from which it can be isolated in a disease ...

Platelet‐Rich Fibrin (PRF) Application and Education in US Graduate Programs: A Cross‐Sectional Study

open access: yesJournal of Dental Education, EarlyView.
ABSTRACT The aim of this cross‐sectional study was to assess platelet‐rich fibrin (PRF) application and education in clinical use among US graduate periodontology, endodontic, and oral and maxillofacial surgery programs. A survey questionnaire was electronically distributed to 84 oral and maxillofacial surgery (OMFS), 46 endodontic, and 46 ...

Higher Energy Demands and Lower Body Condition in a Hot Spring: Comparing Relict Leopard Frogs at Two Thermally Contrasting Sites

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Following range‐wide decline, all remnant populations of the relict leopard frog (Rana onca) in the eastern Mojave Desert of the southwestern USA occupied geothermally influenced hot springs. In recent years, however, several large populations have been established at cold‐water sites.
