Supposing k is equal to the true mixture number k 1⁄4 3, we randomly located three seed points m1, m2, and m3 in the input space as shown in Fig. 2a, where the data constitute three well-separated clusters. Moreover, we initialized each of the js to be an identity matrix, and all js to be zero, i.e., we initialized 1 1⁄4 2 1⁄4 3 1⁄4 13 . Also, we set the learning rates 1⁄4 0:001 and 1⁄4 0:0001....

We report here that compound heterozygosity for hemoglobin Korle-Bu (HbKB) and HbC (j36 Glu + Lys) is associated with moderate chronic hemolytic anemia with microcytosis. To understand the pathogenesis of this syndrome, we have studied the effect of Hb Korle-Bu (KB = 873 Asp + Asn) on the crystallization of HbC. We have previously established that fetal Hb (HbF) inhibits the crystallization of ...

Erythrocyte indices used to differentiate between iron deficiency anaemia (IDA) and thalassaemias have been studied mainly in countries with a high prevalence of IDA or beta-thalassaemias. This study was carried out in the United Arab Emirates where alpha-thalassaemias are prevalent. We studied the predictive value and Youden index of several indices in 85 children aged 6 months to 12 years wit...

CASE REPORT A 65-year-old man presented to our hospital with 4 months of fatigue and weakness. He denied any bleeding manifestations and had pallor on examination. Laboratory test results showed hemoglobin of 8.2 gm/dL with microcytosis and low iron stores. There was no peripheral eosinophilia. Liver and renal function tests were normal. Upper endoscopy was ordered for evaluation of iron defici...

Parasitic infections are prevalent in Thailand. The parasites' relationship with anemia and eosinophilia has been rarely reported due to limited health care access, especially in rural areas. We studied the prevalence and relationship between eosinophilia, anemia and parasitism in 169 Thai-Karens from Mae Lamung and Mae Chan subdistricts, Umphang district, Tak Province, using an automated compl...
