Framing control policies to mitigate the impact of invasive plants on indigenous biodiversity within Sustainable Development Goals (SDG) framework is primary objective this work. Using reported ecological dynamics species \textit{Lantana camara}, we develop a minimal three-species network model, where each node follows generalized Lotka-Volterra (GLV) dynamical equations. Employing Lie algebra and theory, establish model's controllability accessibility criteria. Through nonlinear...

Semiconductor detectors with Silicon as the sensor material are widely used in High Energy Physics (HEP) experiments for high precision tracking and determination of primary secondary vertices good spatial resolution. They close to interaction point, so they prone radiation damage due fluence produced particles. The choice semiconductor is based on signal noise ratio, multiple scattering, pulse timing hardness. In this paper, we compare suitability (Si), Germanium (Ge), Gallium Nitride...

Fragmentation functions are a key component of quantum chromodynamics (QCD) calculations based on the factorisation approach. They typically determined from analysis electron\textendash positron ($\rm e^-e^+$) and proton ep$) collision data. Recent measurements charm-hadron spectra ratios abundances in pp collisions have questioned universality fragmentation across leptonic hadronic systems.

Fluctuations-driven complex oscillations are experimentally observed in cellular systems such as hepatocytes, cardiac cells, neuronal etc. These generally operating regimes far from thermodynamic equilibrium. To study nonequilibrium properties energy dissipation stochastic oscillations, we consider modeling of two nonlinear biological oscillators, namely, the intracellular calcium (Ca$^{2+}$) oscillation model and Hindmarsh-Rose for dynamics. models exhibit various types like bursting...

In high-energy physics experiments, Monolithic Active Pixel Sensors (MAPS) have become crucial components of vertex and tracking detectors over the past decade due to integration readout circuitry with detection volume in a single chip. The requirement achieve precise vertexing capabilities for upgrade HEP such as ALICE at LHC ePIC EIC, has implied strong R&D towards an ultra-thin (a few tens μm), bent, wafer-scale silicon sensors produced stitching technology. Recent ongoing activities...

Control studies in ecological models of networks involving invasive plants can offer tangible management strategies. Framing control policies to tackle problems posed by on indigenous plant diversity under the sustainable developmental goals framework is main motivation this paper. Based reported experimental and theoretical observations, we propose minimal direct interactions \textit{Lantana camara} with other entitites e.g. (denoted Control-plant) soil microbes.
