Temperature effects on optical characteristics of CdSe thin films Gullu, H. H.; Isik, M.; Surucu, O.; Hasanlı, Nızamı; Parlak, Mehmet (Elsevier BV, 2021-03-01) CdSe is one of the significant members of II-VI type semiconducting family and it has a wide range of technological applications in which optoelectronic devices take a special position. The present paper reports the struct...
Million-year-old DNA sheds light on the genomic history of mammoths van der Valk, Tom; et. al. (Springer Science and Business Media LLC, 2021-2-17) Temporal genomic data hold great potential for studying evolutionary processes such as speciation. However, sampling across speciation events would, in many cases, require genomic time series that stretch well back into th...
Arid4b alters cell cycle and cell death dynamics during mouse embryonic stem cell differentiation. Güven, Gözde; Terzi Çizmecioğlu, Nihal (2021-02-09) Cell division and death play an important role in embryonic development. Cell specialization is accompanied with slow proliferation and quiescence. Cell death is important for morphogenesis. Gene expression changes during ...
Defect-deferred correction method based on a subgrid artificial viscosity model for fluid-fluid interaction AĞGÜL, MUSTAFA; Kaya Merdan, Songül (Elsevier BV, 2021-02-01) © 2020 IMACSA defect-deferred correction method, increasing both temporal and spatial accuracy, for fluid-fluid interaction problem with nonlinear interface condition is considered by geometric averaging of the previous tw...
New generalized almost perfect nonlinear functions Özbudak, Ferruh; Salagean, Ana (2021-02-01) APN (almost perfect non-linear) functions over finite fields of even characteristic are widely studied due to their applications to the design of symmetric ciphers resistant to differential attacks. This notion was recentl...
Liftable homeomorphisms of cyclic and rank two finite abelian branched covers over the real projective plane Atalan, Ferihe; Medetogullari, Elif; Ozan, Yıldıray (Elsevier BV, 2021-02-01) © 2020 Elsevier B.V.In this note, we investigate the property for regular branched finite abelian covers of the real projective plane, where each homeomorphism of the base (preserving the branch locus) lifts to a homeomorp...
The synthesis of chiral β-naphthyl-β-sulfanyl ketones via enantioselective sulfa-Michael reaction in the presence of a bifunctional cinchona/sulfonamide organocatalyst Tözendemir, Deniz; Tanyeli, Cihangir (2021-02-01) Cinchona alkaloid-derived organocatalysts are widely employed in various asymmetric transformations, yielding products with high enantiopurity. In this respect, a bifunctional quinine-derived sulfonamide organocatalyst was...
