The PPM data compression scheme has set the performance standard in lossless compression of text throughout the past decade. PPM is a "nite-context statistical modelling technique that can be viewed as blending together several "xed-order context models to predict the next character in the input sequence. This paper gives a brief introduction to PPM, and describes a variant of the algorithm, ca...

— To attain a wider range of data rates in pulse position modulation (PPM) schemes with constrained pulse durations, the sender can repeat a PPM symbol multiple times, forming a super-symbol. In addition to the slot and symbol synchronization typically required for PPM, the receiver must also properly align the noisy super-symbols. We present a low-complexity approximation of the maximum-likeli...

A field experiment was conducted during 2006-2007 and 2007-2008 seasons at Herbal garden, Rajendranagar, Hyderabad, India to study the influence of exogenous application of CPPU and GA yield, 3 fruit quality characters and seedlessness in watermelon. The experiment consists of 12 treatments (CPPU-50 ppm (T ), CPPU-100 ppm (T2), CPPU-200 ppm (T3), GA -100 ppm(T ), GA -200 ppm(T ), CPPU 50 ppm + ...

An inhalation teratology study was conducted in rats at 10, 50 and 250 ppm ethylene glycol monoethyl ether (EGEE) and in rabbits at 10, 50 and 175 ppm EGEE. This study was designed to supplement a study conducted for NIOSH which showed teratogenic effects in rats at 200 ppm EGEE and in rabbits at about 160 ppm EE. In this study, EGEE was found not to cause teratogenic effects at concentrations ...

PURPOSE To estimate the overall effect of 1000 ppm F relative to 250 ppm F toothpaste. METHODS Experimental caries increment studies from the dental literature, which compared 1000 ppm with 250 ppm fluoride toothpastes, were summarized using meta-analytic methods. RESULTS The overall caries reduction of 1000 ppm F relative to 250 ppm F paste was estimated to be 0.142 (95%-CL: 0.074-0.210) w...

OBJECTIVES This study sought to assess the impact of permanent pacemaker (PPM) implantation on clinical outcomes among patients undergoing transfemoral transcatheter aortic valve implantation (TAVI). BACKGROUND TAVI is associated with atrioventricular-conduction abnormalities requiring PPM implantation in up to 40% among patients treated with self-expanding prostheses. METHODS Between 2007 ...
