INTRODUCTION Polyphosphates are used for a wide variety of industrial applications due to their sequestering and dispersing properties. Polyphosphate samples are commonly characterized by various end-group titration methods that provide an estimate of average polyphosphate chain length, but no information on the relative amounts of individual polyphosphate oligomers. Manufacturers and end-users...

This paper describes a method for building a cognitive map of a virtual urban environment. Our routines enable virtual humans to map their environment using a realistic model of perception. We based our implementation on a computational framework proposed by Yeap and Jefferies (Yeap & Jefferies 1999) for representing a local environment as a structure called an Absolute Space Representation (AS...

INTRODUCTION Approximately 54% of civilian pilots rely on ophthalmic lenses to correct defective vision in order to maintain a valid airman medical certificate. This report reviews aviation accidents and incidents where the use or misuse of ophthalmic devices was considered to have been a contributing factor in the mishap. METHODS The NTSB's Aviation Accident/Incident Database and the FAA's I...

Most automatic speech recognizers (ASRs) concentrate on read speech, which is different from spontaneous speech with disfluencies. ASRs cannot deal with speech with a high rate of disfluencies such as filled pauses, repetitions, lengthening, repairs, false starts and silence pauses. In this paper, we focus on the feature analysis and modeling of the filled pauses “ah,” “ung,” “um,” “em,” and “h...

The automated storage and retrieval systems (ASRS) are major material handling support that commonly used in the factories, distribution centers, warehousing, non-manufacturing environments. These robot-based increasingly applied centers of high demand e-commerce operations because their less space requirement, higher operational flexibility continuous ability to work thereby continuously produ...

Background: In China, chronic obstructive pulmonary disease (COPD) was accounted for a quarter of the global COPD population and has become large economic burden. However, comprehensive picture burden, is not readily available all provinces China.  Methods: Using GBD 2019, we analyzed incidence, prevalence, mortality, disability-adjusted life years (DALYs) attributable to across China corres...

Exposure to household air pollution from solid fuels (HAP) is associated with stroke. However, few studies have assessed stroke burden attributable HAP globally and made comparisons across countries. We aimed estimate the spatiotemporal trends in mortality 204 countries territories 1990 2019. Data on 2019 were obtained Global Burden of Disease Study estimated numbers age-standardized rates (ASR...

This paper introduces a two-stage system for identifying and expanding abbreviations. It is based on a hybrid architecture where rule-based and statistical methods are combined. The first task of the system is to differentiate abbreviations from other types of unknown words such as names and misspellings. The second task of the system is to identify the intended complete word. The system is eva...

Aims Twelve GP surgeries refer adults with suspected ADHD to Horsham Assessment and Treatment Service (ATS). Patients are referred by GPs via letter an adult self-report scale (ASRS). Letter contents variable some referrals rejected. There is no gold standard or national guideline for what referral information required. We used a combination of guidelines advice from The Royal College Psychiatr...

This study aims to estimate the prevalence of symptoms of attention-deficit/hyperactivity disorder (ADHD) in parents of children with autism spectrum disorder (ASD). This is a cross-sectional study conducted with the parents of 89 children previously diagnosed with ASD. The research instrument used was the 18-item Adult ADHD Self-Report Scale (ASRS). Symptoms of ADHD were present in 10.4% of th...
