Extremal graphs with minimum number of connected subgraphs in a given family
The subgraph number of a vertex in a graph is defined as the number of connected subgraphs containing that vertex. The graph and its vertex which correspond to the minimum subgraph number among all graphs on $n$ vertices and $k$ cut vertices have been characterised. Further, using this characterisation, the graphs with the minimum number of connected subgraphs among all graphs on $n$ vertices and $k$ cut vertices, with girth at least $k$, have been obtained. This turns out to characterise the g…

Fusion and Fission of Particle-like Chiral Nematic Vortex Knots
Vortex knots have been seen decaying in many physical systems. Here we describe topologically protected vortex knots, which remain stable and undergo fusion and fission while conserving a topological invariant analogous to that of baryon number. While the host medium, a chiral nematic liquid crystal, exhibits intrinsic chirality, cores of the vortex lines are structurally achiral regions where twist cannot be defined. We refer to them as "dischiralation" vortex lines, in analogy to dislocations…

VRAE: Vertical Residual Autoencoder for License Plate Denoising and Deblurring
In real-world traffic surveillance, vehicle images captured under adverse weather, poor lighting, or high-speed motion often suffer from severe noise and blur. Such degradations significantly reduce the accuracy of license plate recognition systems, especially when the plate occupies only a small region within the full vehicle image. Restoring these degraded images a fast realtime manner is thus a crucial pre-processing step to enhance recognition performance. In this work, we propose a Vertica…

Enumeration kernels for Vertex Cover and Feedback Vertex Set
Enumerative kernelization is a recent and promising area sitting at the intersection of parameterized complexity and enumeration algorithms. Its study began with the paper of Creignou et al. [Theory Comput. Syst., 2017], and development in the area has started to accelerate with the work of Golovach et al. [J. Comput. Syst. Sci., 2022]. The latter introduced polynomial-delay enumeration kernels and applied them in the study of structural parameterizations of the \textsc{Matching Cut} problem an…

Vorticity Packing Effects on Turbulent Transport in Decaying 2D Incompressible Navier-Stokes Fluids
This paper investigates the role of initial vorticity packing fractions on the transport properties of decaying incompressible two-dimensional Navier-Stokes turbulence at very high Reynolds numbers and spatial resolutions. Turbulence is initiated via the Kelvin-Helmholtz instability and evolves through nonlinear inverse energy cascades, forming large-scale coherent structures that dominate the flow over long eddy turnover times. The initial vorticity packing fraction and circulation direction l…

Numerical Investigation of Natural Convection Dynamics in Open-Ended Vertical Channels with Different Aspect Ratios
Understanding the thermal and flow fields associated with natural convection is of great importance in the design and manufacture of passive cooling systems, solar collectors, and ventilation systems. The aim of this study is to numerically investigate the naturally driven flow behaviour in open-ended vertical channels. Specifically, laminar airflow (Rayleigh number of 5*10^5) is naturally driven through a vertical channel that is asymmetrically heated with a uniform heat flux of (2043 w/m^2) .…
