On-line recognition of handwritten chinese characters based on hidden markov models
Difficulties in Chinese character recognition due to numerous strokes usually warped into a cursive form and a much larger set of characters. In this paper, we propose a hidden Markov model (HMM)Expand

Detection of astrovirus in pediatric stool samples by immunoassay and RNA probe.
Two new astrovirus assays, a rapid biotin-avidin enzyme immunoassay (EIA) and RNA probe hybridization, were developed and compared with an established astrovirus assay, an indirect EIA, and immuneExpand

Pectin-like acidic polysaccharide from Panax ginseng with selective antiadhesive activity against pathogenic bacteria.
Previous studies have revealed the inhibitory effects of an acidic polysaccharide purified from the root of Panax ginseng against the adhesion of Helicobacter pylori to gastric epithelial cells andExpand

Inhibition of pathogenic bacterial adhesion by acidic polysaccharide from green tea (Camellia sinensis).
An acidic polysaccharide CS-F2 from Camellia sinensis was examined to characterize its anti-adhesive effects against pathogenic bacteria, most notably Helicobacter pylori, Propionibacterium acnes,Expand

Use of Hangeul Twitter to Track and Predict Human Influenza Infection
Influenza epidemics arise through the accumulation of viral genetic changes. The emergence of new virus strains coincides with a higher level of influenza-like illness (ILI), which is seen as a peakExpand

Insight into autoproteolytic activation from the structure of cephalosporin acylase: a protein with two proteolytic chemistries.
Cephalosporin acylase (CA), a member of the N-terminal nucleophile hydrolase family, is activated through sequential primary and secondary autoproteolytic reactions with the release of a pro segment.Expand

Antiviral effects of black raspberry (Rubus coreanus) juice on foodborne viral surrogates.
Abstract Human noroviruses (HuNoVs) are the most frequent cause of foodborne viral gastroenteritis, causing approximately 90% of non-bacterial epidemic outbreaks around the world. Rubus coreanus is aExpand

Inhibition of Pathogen Adhesion to Host Cells by Polysaccharides from Panax ginseng
PG-F2 and PG-HMW from Panax ginseng are pectin-type polysaccharides and PG-HMW might be an arabinogalactan. They demonstrated strong anti-adhesive activities against oral and skin pathogens to hostExpand

Insight into structural diversity of influenza virus haemagglutinin.
Influenza virus infects host cells through membrane fusion, a process mediated by the low pH-induced conformational change of the viral surface glycoprotein haemagglutinin (HA). We determined theExpand

The crystal structure of ferritin from Helicobacter pylori reveals unusual conformational changes for iron uptake.
The crystal structure of recombinant ferritin from Helicobacter pylori has been determined in its apo, low-iron-bound, intermediate, and high-iron-bound states. Similar to other members of theExpand
