We present the following results about IDA* and related algorithms: We show that IDA* is not asymptotically optimal in all of the cases where it was thought to be so. In particular, there are trees satisfying all of the conditions previously thought to guarantee asymptotic optimality for IDA*, such that IDA* will expand more than O(N) nodes, where N is the number of nodes eligible for expansion...

Abscission is a developmental process that enables plants to shed unwanted organs. In Arabidopsis, the floral organ abscission is regulated by a signaling pathway consisting of the peptide ligand IDA, the receptor-like kinases (RLKs) HAE and HSL2, and a downstream MAP kinase (MAPK) cascade. However, little is known about the molecular link between ligand-receptor pairs and intracellular signali...

Background: Iron deficiency anemia (IDA) is the most common micronutrient deficiency in the world and almost a third of the world's population is involved with IDA. It even in mild type, could lead to serious disorders such as impairment of learning and mental focus. Reduction of iron resources results in an imbalance in the physiological function. With regard to the role of iron in myelination...

Inflammation can lead to malabsorption of important micronutrients such as iron. Malabsorption and nutritional deficiency can be caused by a variety of pathological and environmental factors causing a range of other symptoms commonly caused by both H. pylori infection and coeliac disease (CD). National guidelines suggest the routine taking of duodenal biopsies to exclude CD when investigating p...

To the Editor I read with interest the correspondence relating to recent articles published in the Journal describing mathematical approaches to the differentiation of thalassemia trait (TT) and iron deficiency anemia (IDA). 1-3 I found this and the accompanying authors' responses to be thoughtful and informative. There has been a clear revival of interest in the application of discriminant fun...

Abstract Controversy exists regarding the association between Iron Deficiency Anemia (IDA), iron status, and Febrile Convulsion (FC) during childhood. In this article, a systematic review and meta-analysis is conducted in order to determine possible association and the degree of association between these statuses and FC. To identify all studies related to IDA and FC, various references such as ...

Plants constantly renew during their life cycle and thus require to shed senescent and damaged organs. Floral abscission is controlled by the leucine-rich repeat receptor kinase (LRR-RK) HAESA and the peptide hormone IDA. It is unknown how expression of IDA in the abscission zone leads to HAESA activation. Here we show that IDA is sensed directly by the HAESA ectodomain. Crystal structures of H...

Background: Iron deficiency, is a common worldwide complication, especially in preschool children. Iron deficiency anemia (IDA) is associated with changes in the mental and motor development, defects of immune system, cardiovascular, diseases and disruption of lipid profile. In IDA, the occurrence of dyslipidemia is controversial. We aimed to investigate the association between IDA and serum li...

In this paper, the technique of local linear dynamics assignment is presented, which complements the powerful Interconnection and Damping Assignment Passivity Based Control (IDA-PBC) methodology. In IDA-PBC, nonlinear state feedback controllers are designed by matching the system’s dynamics with a desired Port-Hamiltonian (PH) state representation. The latter consists of an energy function, whi...
