Square prism micropillars improve osteogenicity of poly(methyl methacrylate) surfaces
Hasturk, O.; Ermiş, Muammer; Demirci, U.; Hasırcı, Nesrin; Hasırcı, Vasıf Nejat (2018-05-01)
Osteogenicity and osteointegration of materials is one of the key elements of the success of bone implants. Poly(methyl methacrylate) (PMMA) is the basic compound of bone cement and has been widely investigated for other orthopedic applications, but its poor osteointegration and the subsequent loosening of implant material limits its widespread use as bone implants. Micropillar features on substrate surfaces were recently reported to modulate cell behavior through alteration of cell morphology and promotion...

Recognition of objects with subtle differences has been used in many practical applications, such as car model recognition and maritime vessel identification. For discrimination of the objects in fine-grained detail, we focus on deep embedding learning by using a multi-task learning framework, in which the hierarchical labels (coarse and fine labels) of the samples are utilized both for classification and a quadruplet-based loss function. In order to improve the recognition strength of the learned features,...
Square prism micropillars on poly(methyl methacrylate) surfaces modulate the morphology and differentiation of human dental pulp mesenchymal stem cells
Hasturk, Onur; Ermiş Şen, Menekşe; Demirci, Utkan; Hasırcı, Nesrin; Hasırcı, Vasıf Nejat (2019-06-01)
Use of soluble factors is the most common strategy to induce osteogenic differentiation of mesenchymal stem cells (MSCs) in vitro, but it may raise potential side effects in vivo. The topographies of the substrate surfaces affect cell behavior, and this could be a promising approach to guide stem cell differentiation. Micropillars have been reported to modulate cellular and subcellular shape, and it is particularly interesting to investigate whether these changes in cell morphology can modulate gene express...
Broad band metamaterial absorber based on wheel resonators with lumped elements for microwave energy harvesting
KARAASLAN, MUHARREM; BAĞMANCI, MEHMET; ÜNAL, EMİN; AKGÖL, OĞUZHAN; ALTINTAŞ, OLCAY; Sabah, Cumali (Springer Science and Business Media LLC, 2018-05-01)
A new metamaterial absorber structure is designed and characterized both numerically and experimentally for microwave energy harvesting applications. The proposed structure includes four wheel resonators with different dimensions, from which the overall response of the structure can then be obtained by summing all the overlapping frequency responses corresponding to each dimension. The essential operation frequency range of the wheels is selected in such a way that the energy used in wireless communications...
Long wave runup on piecewise linear topographies
Kanoğlu, Utku (1998-11-10)
We study long-wave evolution and runup on piecewise linear one- and two-dimensional bathymetries analytically and experimentally with the objective of understanding certain coastal effects of tidal waves. We develop a general solution method for determining the amplification factor of different ocean topographies consisting of linearly varying and constant-depth segments to study how spectral distributions evolve over bathymetry, and apply our results to study the evolution of solitary waves. We find asympt...
