Objective Tumour budding formed by histologically undifferentiated cancer cells beyond the border of the tumour margin is associated with lymph node metastasis. However, hollow tumour nests, a possible histologically advanced phenotype of tumour budding, have not been discussed. We examined whether hollow spheroids exist beyond the border of the invasive margin and are associated with metastasi...
Using computer simulations, we explore how thermal noise-induced randomness in a self-assembled photonic crystal affects its band gaps (PBGs). We consider two-dimensional comprised of array parallel dielectric hard rods infinite length with circular or square cross section. find the PBGs can exist over large range intermediate packing densities. Counterintuitively, largest gap does not always a...
Abstract Traditional hollow concrete filled steel tube components are mainly used in the transformer power structure. In order to improve mechanical properties and application scope of components, a new type reinforcement high-strength combination structure is proposed. Given that construction system frequently an eccentric stress condition throughout structural system, finite element analysis ...
in this study the synthesis of molybdenum oxide nano-whiskers with circular cross-section is performed. in some areas, it was observed that also some whiskers have open tips exhibiting their hollow structures. these whiskers have side dimensions ranging 2-5 μm with an average diameter in the nanometer rang. the structure suggested the vapor-liquid-solid growth mechanism (vls). scanning elect...
GFRP sections with filler concrete material form promising structural components for structures; therefore, the performance of them has been investigated increasing popularity. However, these composites degrades when fully composite action cannot be developed at interface in where literature hosts limited knowledge. Different techniques, such as abraded and sand-bonded surface treatments, were ...
