We introduce the notion of non-malleable non-interactive zero-knowledge (NIZK) proof systems. show how to transform any ordinary NIZK system into one that has strong non-malleability properties. then elegant encryption scheme Naor and Yung (1990) can be made secure against strongest form chosen-ciphertext attack by using a instead standard proof. Our is simple describe works in cryptographic model under, general assumptions. The realized assuming existence trapdoor permutations.
This paper addresses the smallest grammar problem: What is context-free that generates exactly one given string /spl sigma/? a natural question about fundamental object connected to many fields such as data compression, Kolmogorov complexity, pattern identification, and addition chains. Due problem's inherent our objective find an approximation algorithm which finds small for input string. We focus attention on ratio of (and implicitly, worst case behavior) establish provable performance...
We evaluated the use of botulinum toxin-A in treating patients with idiopathic detrusor overactivity refractory to anticholinergics.This double-blind, placebo controlled trial randomized participants intradetrusor injections 200 U (16 patients) or (18 patients). The primary outcome measure was change maximum cystometric capacity. Secondary measures included changes overactive bladder symptoms, post-void residual, pressure during filling cystometry and reflex volume. Quality life assessed...
We show that every language in NP has a (black-box) concurrent zero-knowledge proof system using O/spl tilde/(log n) rounds of interaction. The number our protocol is optimal, the sense any outside BPP requires at least /spl Omega//spl interaction order to be proved black-box zero-knowledge. property main under assumption there exists collection claw free functions. Assuming only existence one-way functions, we n)-round arguments for all languages NP.
To report our long-term experience of sacral neuromodulation (SNM) for various lower urinary tract dysfunctions but with a focus on efficacy, safety, re-interventions and degree success.This is single tertiary referral centre study that included 217 patients (86% female) who received an implantable pulse generator (IPG) (Interstim™, Medtronic, Minneapolis, USA) between 1996 2010. Success was considered if the initial ≥50% improvement in any primary voiding diary variables persisted compared...
Genital examinations are challenging for medical students to learn in part due practice opportunities. In an attempt address this, we introduced clinical teaching associates (CTAs) who teach third year and allow male intimate be practiced on themselves. A single-blinded parallel-group RCT was conducted, recruiting 96 students. The control group only given access the current curriculum (lectures, videos, models) whilst other offered this a session with CTAs, professionally trained, allowing...
Abstract Guy's, King's, and St. Thomas's School of Medicine encourages students to learn anatomy from human dissection. Today, there is a worldwide move anatomy‐based teaching away dissection prosection. This study investigates how attitudes toward vary with gender ethnicity. We assessed students' reactions concerns regarding the dissecting room, any coping strategies they use combat them, analyzed effective methods medical dental students. Three questionnaires were distributed amongst 474...
Corrected by: A prospective comparison of endoscopic ultrasound-guided fine needle aspiration results obtained in the same lesion, with and without styletEndoscopy 2011; 43(02): 168-168DOI: 10.1055/s-0030-1256175 See also: Commentaire de travail A.

We construct a secure protocol for any multiparty functionality that remains (under relaxed definition of security introduced by Prabhakaran and Sahai (STOC '04)) when executed concurrently with multiple copies itself other protocols, without assumptions on existence trusted parties, common reference string, honest majority or synchronicity the network. The relaxation is obtained allowing ideal-model simulator to run in quasipolynomial (as opposed polynomial) time. Quasipolynomial simulation...
A retrospective analysis was conducted comparing open and percutaneous repair of ruptured Achilles tendon, over a 14-year period. One hundred eight patients were identified; 70 underwent traditional 38 had modified Ma & Griffith repair. The mean operating time with 28.5 minutes compared to 45.9 in the group ( p = < .0001). Comparable results obtained subjective range movement, stiffness, power both groups at discharge from clinic. In there four cases rerupture (5.7%), deep infections...
We investigate the feasibility of a variety cryptographic tasks with imperfect randomness. The kind randomness we consider are entropy sources, such as those considered by Santha and Vazirani, Chor Goldreich, Zuckerman. show following: (1) certain like bit commitment, encryption, secret sharing, zero-knowledge, non-interactive secure two-party computation for any non-trivial junction impossible to realize if parties have access sources slightly less-than-perfect entropy, i.e., These results...
OBJECTIVE To determine whether botulinum toxin‐A (BTX‐A) treatment has an effect on the quality of life (QoL) patients with overactive bladder (OAB) refractory to anticholinergics. PATIENTS AND METHODS This was a single centre, randomized, double‐blind, placebo‐controlled trial. Participants were men and women idiopathic detrusor overactivity (IDO). randomised receive either 200 U BTX‐A (Botox®, Allergan Inc., Irvine, CA, USA; n = 16) or placebo ( 18) via trigone‐sparing flexible cystoscopic...
A 57-year-old woman with a diagnosis of idiopathic recurrent pancreatitis and progressive epigastric pain radiating to her back was admitted the hospital. Abdominal computed tomography (CT) showed suspicious 3-cm pancreatic head mass involving superior mesenteric artery (SMA) vein. Endoscopic ultrasound (EUS) bile duct main dilatation changes compatible chronic pancreatitis. However, EUS-guided fine needle aspiration cytology negative on three occasions.
