Early-detection scheme based on sequential tests for low-latency communications.

We propose an early-detection scheme to reduce communications latency based on sequential tests under finite blocklength regime for a fixed-rate transmission without any feedback channel. The proposed scheme processes observations sequentially to decide in favor of one of the candidate symbols. Such a process stops as soon as a decision rule is satisfied or waits for more samples under a given accuracy.

Incidence and risk factors of oral antibiotic-associated diarrhea in an outpatient pediatric population.

Background: Little information is available on the epidemiologic characteristics of antibiotic-associated diarrhea (AAD) in children. The authors' aim was to evaluate the incidence of AAD in an outpatient pediatric population and to identify risk factors.

Methods: Children aged 1 month to 15.

[Early detection of visual disorders by pediatricians].

A group of pediatricians from Northern France whose aim was to develop research projects in ambulatory pediatrics, elaborated a method of rapid assessment of visual acuity that can be applied by the pediatrician in the consulting room. This test was included in the routine examination of children between the age of 2 1/2 and 4, the age of 3 years being the most appropriate. The method is simple, reliable, reproducible and cheap since it is part of the pediatrician's consultation.
