On complex hybrid numbers: Algebraic structures, matrix representations, and geometric interpretations

Kuwait Journal of Science
This work introduces complex hybrid numbers, an extension of hybrid numbers, which are defined as Z = z0 + z1i + z2ɛ + z3ℎ where zi are complex numbers and iℎ = −ℎi = i + ɛ.

Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells

FEBS Open Bio, EarlyView.
Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.

Differentiation of mouse embryonic stem cells and their hybrids during embryoid body formation

Genetics and Molecular Biology, 2002
We studied the karyotypes of three hybrid clones of mouse embryonic stem cells and murine splenocytes (two having near diploid and one having near tetraploid chromosome numbers) and the characteristics of their differentiation during the formation of ...

A Study on Horadam Hybrid Numbers

TURKISH JOURNAL OF MATHEMATICS, 2020
In this paper, we study Horadam hybrid numbers. For these numbers, we give the exponential generating function, Poisson generating function, generating matrix, Vajda's, Catalan's, Cassini's, and d'Ocagne's identities. In addition, we offer Honsberger formula, general bilinear formula, and some summation formulas for these numbers.

Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway

FEBS Open Bio, EarlyView.
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

Two-stage hybrid algorithm for recognition of industrial slab numbers with data quality improvement

Complex & Intelligent Systems, 2022
As the unique recognition of each slab, the accurate recognition of slab number is especially critical for the hot rolling production process. However, the collected data are often of low quality due to poor production environment conditions, making ...
