Some Nonunique Common Fixed Point Theorems in Symmetric Spaces through Property

International Journal of Mathematics and Mathematical Sciences, 2013
We introduce a new class of mappings satisfying the “common limit range property” in symmetric spaces and utilize the same to establish common fixed point theorems for such mappings in symmetric spaces.

Multiple and Precessing Collimated Outflows in the Planetary Nebula IC 4634

, 2008
With its remarkable double-S shape, IC 4634 is an archetype of point-symmetric planetary nebulae (PN). In this paper, we present a detailed study of this PN using archival HST WFPC2 and ground-based narrow-band images to investigate its morphology, and ...

The three-dimensional structure of the Eta Carinae Homunculus [PDF]

, 2014
We investigate, using the modeling code SHAPE, the three-dimensional structure of the bipolar Homunculus nebula surrounding Eta Carinae, as mapped by new ESO VLT/X-Shooter observations of the H2 $\lambda=2.12125$ micron emission line.

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Measurement of FRFs and Modal Identification in Case of Correlated Multi-Point Excitation

Shock and Vibration, 2008
The modal identification of large and dynamically complex structures often requires a multi-point excitation. Sine sweep excitation runs are applied when it is necessary to concentrate more energy on each line of the frequency spectrum.

On Janowski Type Harmonic Meromorphic Functions with respect to Symmetric Point

Journal of Function Spaces, 2021
In this paper, we define a new class of Sakaguchi type-meromorphic harmonic functions in the Janowski domain that are starlike with respect to symmetric point.

A Representation of a Point Symmetric 2-Structure by a Quasi-Domain [PDF]

Results in Mathematics, 2013
The authors study chain structures \(\Sigma(P,{\mathcal G}_1,{\mathcal G}_2,{\mathcal K})\). They consider a particular class called symmetric 2-structures. This implies that each chain \(K\in{\mathcal K}\) admits a reflection mapping chains onto chains. Select a chain \(E\in{\mathcal K}\).

High-velocity collimated outflows in planetary nebulae: NGC 6337, He 2-186, and K 4-47

, 1999
We have obtained narrow-band images and high-resolution spectra of the planetary nebulae NGC 6337, He 2-186, and K 4-47, with the aim of investigating the relation between their main morphological components and several low-ionization features present in

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Fixed Point Theorem for Multivalued Non-self Mappings in Partial Symmetric Spaces

Topological Algebra and its Applications, 2021
In this paper, we proved a fixed point theorem for multi-valued non-self mappings in partial symmetric spaces. In doing so, we extended and generalized the results in literature by employing a convex structure for multi-valued non-self mappings using ...
