In this paper we study finding the $(k,l)$-core problem on a tree which the vertices have positive or negative weights. Let $T=(V,E)$ be a tree. The $(k,l)$-core of $T$ is a subtree with at most $k$ leaves and with a diameter of at most $l$ which the sum of the weighted distances from all vertices to this subtree is minimized. We show that, when the sum of the weights of vertices is negative, t...

Introduction: Application of proper approaches as a logical framework for creating core curriculum prevents making additional information in curricula. This study aimed to introduce some useful approaches for determining core curriculum in medical science. Methods: This review study was done by electronic searching (PubMed, ERIC, Google Scholar) as well as manual searching (library resources)....

Clinical and empirical evidence confirming the relationship between core shame and psychopathology types has shown that core shame is the cause of many mental disorders, in this regard investigating the origin of this emotion in the preventive direction and also studying underlying factors for treatment is important. In this paper, by a theoretical review of the causes and origins of this emoti...

This study presents a single-core and a multi-core processor architecture for health monitoring systems where slow biosignal events and highly parallel computations exist. The single-core architecture is composed of a processing core (PC), an instruction memory (IM) and a data memory (DM), while the multi-core architecture consists of PCs, individual IMs for each core, a shared DM and an interc...

the core sediment samples were analysed for grain size, carbonates (caco3), organic carbon (oc) to obtain a preliminary view of its environmental conditions near point calimere along the southeast coast of vedaranyam, india.the high concentration of sand in the core is attributed to the tidal influence at the akkarapallivasal river mouth. the sea water which enters the river suspends the floccu...

this research paper lays stress on philosophies of human desire. all the human being has some psychical need in addition to physical needs. and to satisfy the psychical needs, there is a need for stimulants, more in case of exclusive pedestrian precincts. having exclusively pedestrian precincts/cores in city design draws its inspiration from the fact that public zones, accessible to majority of...

in this work, hierarchical wo3 core-shell microspheres were synthesized via a facile template-free precipitation method. gas sensing properties of the synthesized powder to acetone and some other volatile organic compounds were comparatively investigated with commercial wo3 nanoparticles. the synthesized and commercial powders were characterized by x-ray diffraction, scanning electron microscop...

the photocatalytic coatings were prepared via incorporating the modified titania nanoparticles into epoxy-based inorganic-organic hybrid coatings. titania nanoparticles were first synthesized from tetra-n-butyl titanate using sol-gel methods by two different calcination treatments, i.e., in mild condition (80°c) and 500°c. the formed anatase nanoparticles were further modified as titania-silica...
