Notice of RetractionAfter careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE's Publication Principles.We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.The adsorption of arsenate and arsenite onto a Ce-La binary hydroxide, a mixture of mainly Ce(VI) and La(III) hydroxides, as a recovery of waste ceria glass polishing powder, encapsulated in calcium alginate beads was studied under various pH values, adsorbent dose, and contact time. The effect of sorbent mass in the gel bead, solution pH, contact time and As(III) and As(V) concentration on sorption has been investigated. A 8% (w/v) of CLH in the gel beads was found to provide both good sorption performance and spherical shape. The optimum pH range was observed to be with 5-10 for As(III) and 4-7 for As(V). Equilibrium was reached after 48 h contact time for As(III) and 24 h for As(V), respectively. The adsorptive rate of both arsenic species on the adsorbent obeys pseudo second order kinetic models (R2 >; 0.97). Adsorption isotherm at pH 4.0 for As(III) and at pH 8.0 for As(V) fits the Langmuir model of adsorption over the As concentration range 0.5-250 mg As L-1. The experiment provides also a promising way to use waste as a material for the treatment of other wastes or contaminants from the point of recycling.

The cytogenetic anomaly der(20)del(20)(q11.2q13.3)idic(20)(p11), or idic(20q−) in short form, has been reported in 13 cases of myelodysplastic syndrome, one case of chronic myelomonocytic leukemia, and one case of acute myeloid leukemia since 2004. To our knowledge, it has not previously been described in lymphoid diseases. Here we report the cases of two patients with B-cell acute lymphocytic leukemia (ALL) having a novel idic(20q−). One was a 34-year-old man with B-cell ALL whose leukemic cells at presentation had a karyotype of 45,XY,dic(9;20)(p11;q11.2); at relapse, a small marker chromosome was found coexisting with the dic(9;20). The other was a 39-year-old woman with Ph-positive B-cell-ALL whose leukemic cells contained both t(9;22)(q34;q11.2) and a small marker chromosome. A series of FISH analyses using the appropriate probes revealed the small marker chromosome in both patients to be an idic(20q−), confirming the dic(9;20)(p11;q11.2) in one case and revealing a BCR/ABL fusion gene in the other. One patient achieved complete remission but relapsed; the other did not achieve complete remission. Both patients died with a short survival time, despite receiving intensive chemotherapy. These two cases show that idic(20q−) can appear not only in myeloid diseases but also in lymphoid diseases.

Scalability and high degree of playing continuity are key points to large-scale application of video-on-demand system. This paper presents a peer-to-peer (P2P) video-on-demand system CPVoD based on a cylindrical structure. It can enhance the efficiency of finding data by combining the accuracy and efficiency of DHT and the simplicity and practicability of Gossip protocol. A data scheduling strategy is introduced which starts from the perspective of reducing the expired data. By adding a small amount of local information to the data information exchange process based on Gossip protocol, it can help peers find the optimal download resource and finally enhance the playing continuity of system. A data downloading mathematical model is introduced, which converts the problem of improving the playing continuity of VoD system to the problem of finding the optimal solution for job scheduling with deadline, and a corresponding solution algorithm is also presented. The emulation experiments show that CPVoD can guarantee more than 99% of nodes joining the system normally and obtain a playing continuity more than 95% on the condition that server load is stable.

The prevalence of iron-deficiency anemia in children has decreased owing to the provision of iron-containing infant formula and cereal and food vouchers to children enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). To determine the prevalence of anemia and changes in anemia status in children receiving WIC supplementation. Retrospective cross-sectional and longitudinal analysis of information on WIC participants. Two definitions of anemia were considered separately: Anemia1 and Anemia2, the latter using a more stringent definition of anemia to avoid misclassification. Consecutive cohort of 7053 infants and children aged 6 to 59 months. Prevalence of anemia by age and race or ethnicity and relationship between anemia and sex, birth weight, and weight-for-height z score. Infants aged 6 to 8 months were 3.3 times more likely to be anemic than children aged 36 to 59 months. There was no association between anemia and race, birth weight, sex, or weight-for-height z score. Anemia rates were approximately halved in the more stringently defined Anemia2 group. Among children seen for at least 3 visits (n = 2926), 8.5% developed anemia and 19.1% of initially anemic children remained anemic; an additional 6.6% developed anemia at a third visit after having had 2 normal hemoglobin measurements. Anemia was common in WIC participants, with infants at highest risk. The diagnosis of anemia in black children depends on the cutoff value used. Despite ongoing receipt of WIC benefits, many children develop anemia or remain anemic. Implementation of mandatory follow-up of all anemic infants by WIC or health care providers may be warranted.
