From Struggle to Success: The Osoyoos Indian Band’s Journey into Agritourism and Economic Prosperity
Authors: Ibrahim Zainub , Jaffer Ahmed , McCarthy-Kennedy Fiona 
Published: November 2023

SummaryIn the province of British Columbia, Canada, the Osoyoos Indian Band (OIB) employs agritourism, specifically wine tourism, to serve their community economically and socially. Once on the verge of bankruptcy, they are now one of the wealthiest First Nations in the country, and their participation in the wine industry has played a critical role in this transformation. The OIB has been involved in the wine industry for over three decades. Beginning in 1968 with only 200 acres of vineyard, they currently own and operate one of the largest vineyards in the Okanagan Valley, and an award-winning winery Nk’Mip Cellars – the first Indigenous-owned and operated winery in the world. The winery was part of a broader development plan called the Nk’Mip Project. The project encompassed various planned developments, including the Nk’Mip Desert Cultural Centre which acts as a value-added attraction for those tourists visiting the winery and its vineyards. Economic self-sufficiency through economic development projects is the core belief of the OIB. Chief Louie says that their band has always had a business culture and they have continued to evolve. These developments have allowed the OIB to diversify its revenue streams, protect its lands, and promote its culture and history.Information© The Authors 2023
Ising-like models on Euclidean black holes
Authors: Saeed Mustafa , Husain Viqar 
Published: November 2023

Abstract
We study spin models on Euclidean black hole backgrounds. These resemble the Ising model, but are inhomogeneous with two parameters, the black hole mass and the cosmological constant. We use Monte-Carlo methods to study macroscopic properties of these systems for Schwarzschild and anti-deSitter black holes in four and five dimensions for spin-1/2 and spin-1. We find in every case that increasing the black hole mass causes the spins to undergo a second order phase transition from disorder to order and that the phase transition occurs at sub-Planckian black hole mass.
Quantization of spherically symmetric loop quantum gravity coupled to a scalar field and a clock: the asymptotic limit
Authors: Gambini Rodolfo , Pullin Jorge 
Published: November 2023

Abstract
We continue our work on the study of spherically symmetric loop quantum gravity coupled to two spherically symmetric scalar fields, one which acts as a clock. As a consequence of the presence of the latter, we can define a true Hamiltonian for the theory. The spherically symmetric context allows to carry out precise detailed calculations. Here we study the theory for regions of large values of the radial coordinate. This allows us to define in detail the vacuum of the theory and study its quantum states, yielding a quantum field theory on a quantum space time that makes contact with the usual treatment on classical space times.
Periodic boundary conditions and G
2 cosmology
Authors: Coley A A , Lim W C 
Published: November 2023

Abstract
In the standard concordance cosmology the spatial curvature is assumed to be constant and zero (or at least very small). In particular, in numerical computations of the structure of the Universe using N-body simulations, exact periodic boundary conditions are assumed which constrains the spatial curvature. In order to confirm this qualitatively, we numerically evolve a special class of spatially inhomogeneous G
2 models with both periodic initial data and non periodic initial data using zooming techniques. We consequently demonstrate that in these models periodic initial conditions do indeed suppress the growth of the spatial curvature as the models evolve away from their initial isotropic and spatially homogeneous state, thereby verifying that the spatial curvature is necessarily very small in standard cosmology.
Nanowire breakup via a morphological instability enhanced by surface electromigration
Authors: Khenner Mikhail 
Published: November 2023

Abstract
Using a recent continuum model of a single-crystal nanowire morphological evolution in the applied axial electric field, an axisymmetric evolution of a microscopically rough nanowire surface is computed. Morphological evolution results in a wire breakup into a cylindrical segments (particles). Breakup time and the number of particles are characterized for various levels of the radial and axial surface roughness. It is shown that electromigration and larger surface roughness lead to a shorter breakup time and the increased number of particles.
On a stochastic generalized delayed SIR model with vaccination and treatment
Authors: Marković Milica , Krstić Marija 
Published: November 2023

Abstract
In this paper we consider a stochastic susceptible-infectious-recovered (SIR) epidemiological model which is obtained on the basis of the deterministic SIR epidemiological model with general incidence rate, distributed delay, general treatment and vaccination. For our model we first prove existence and uniqueness of the global positive solution and then we consider conditions under which disease survives in population by proving the existence of ergodic stationary distribution. Also, the stochastic model adopts the disease-free equilibrium from it is deterministic analogue, and we investigate conditions under which it is stable in probability. Finally, the numerical simulations with real life date are carried out to illustrate the theoretical results.

Abstract
To explore the potential of iron-based superconducting (IBS) tapes in high-field applications, IBS pancake coils were dry-wound using the uninsulated IBS tape, supplemented with cowound stainless steel tapes for reinforcement. We have successfully fabricated a double pancake coil (DP-1) and a series-connected coil consisting of six DP coils (DP-6). These coils underwent multiple charging tests in a 35 T resistive magnet and retesting in a 14 T superconducting magnet. After conducting multiple rounds of retesting in two different background field magnets, it was found that the IBS coils did not show any degradation in their current-carrying performance. The critical current (I
c) value of the DP-1 at 4.2 K and 32 T reached 60 A. To systematically evaluate the I
c performance of the six coils in the DP-6, we monitored the V–I curves between 26 voltage taps. The resistive voltage rise was observed at low charging currents, indicating that each coil has suffered different levels of damage. Nevertheless, the overcurrent tests demonstrated that the IBS coil can still carry a current far exceeding its I
c without irreversible degradation. We concluded the possible reasons for these phenomena by analyzing the experimental details and test data. In addition, the coil’s internal structure was observed to assess the quality of coil winding, joint soldering, and epoxy resin impregnation. This study will provide references for the electromagnetic and mechanical properties of IBS tapes under ultra-high magnetic fields and contribute to the future development of higher-performance practical IBS coils.
Contextuality, coherences, and quantum Cheshire cats
Authors: Hance Jonte R , Ji Ming , Hofmann Holger F 
Published: November 2023

AbstractWe analyse the quantum Cheshire cat using contextuality theory, to see if this can tell us anything about how best to interpret this paradox. We show that this scenario can be analysed using the relation between three different measurements, which seem to result in a logical contradiction. We discuss how this contextual behaviour links to weak values, and coherences between prohibited states. Rather than showing a property of the particle is disembodied, the quantum Cheshire cat instead demonstrates the effects of these coherences, which are typically found in pre- and post-selected systems.

Abstract
Silver nanoparticles (AgNPs) are widely utilized in biomedical and antibacterial fields. However, their use poses a risk and danger of Ag+ absorption into human tissue via skin penetration. This study focuses on the facile and eco-friendly approach to synthesizing uniformly distributed and spherically shaped phenol capped AgNPs using Agaricus bisporus. The synthesis process was monitored by UV–vis spectroscopy peak at 430 nm. Further characterizations were performed by XRD, and TEM. The phenol-capped AgNPs (average diameter is 11.81 nm) exhibit excellent colloidal stability in an aqueous solution with a zeta potential of −32.9 mV. The presence of phenols in the AgNPs suspension, which include CAFFICACID, QUERCETIN, GALLIC ACID, ROSMARINIC ACID, SINAPIC, and SYNIRGIC was confirmed by HPLC analysis. The study investigated their antibacterial activity against colonies of palm-hand bacteria, Pseudomonas aeruginosa, and Streptococcus pyogenes bacteria even in small doses was investigated. Damage to the cell wall, mitochondria, and DNA by nanoparticles has been proposed as an antibacterial mechanism. Toxicological parameters such as histological study of skin and vital organ tissue, hematological, serum biochemistry, and fatality incidence were investigated. There were no harmful effects or damage caused by phenol-capped AgNPs in albino mouse organs when compared to the vehicle group. Toxicological evidence supports the use of mycosynthesized phenol-capped AgNPs in non-alcohol hand sanitizer.

Published: November 2023

Abstract
Artificial intelligence (AI) in renewable energy technologies plays a crucial part due to its modeling and performance forecasting. Therefore, a novel AI-based evolving generative adversarial Fuzzy network (EGAFN) has been presented in this paper as a forecasting tool for the efficiency analysis of renewable solar energy for four distinct regions. The power ratings from environmental parameters and solar panels were monitored and recorded for a year. The data pre-processing is primarily applied to improve the system’s function using a data filter. Furthermore, the data’s energy estimation accuracy is enhanced using feature extraction and selection by a multi-objective lionized manta-ray foraging optimizer (MLMRFO). Finally, the hyperparameters of the EGAFN method are optimized by multi-objective optimization. The proposed technique uses an optimized multi-objective algorithm to enhance the energy efficiency of PV systems for solar power production forecasting. The findings show that the suggested technique’s prediction performance is better than earlier methods. Thus, the proposed methodology can assist in increasing energy efficiency and making better use of renewable energy sources.
Ricci solitons on anisotropic fluid spacetime in f(R, T)-gravity
Authors: Khan Suhail , Ali Ahmad T , Gul Uzma 
Published: November 2023

Abstract
In this paper we study the behaviour of anisotropic fluid spacetimes in f(R, T)-gravity for admitting Ricci Soliton. We obtain the form of tangential pressure of the fluid for steady, shrinking and expanding Ricci soliton when Ricci soliton vector field becomes a Killing vector field. Modified Poisson and Liouville equations are derived from the Ricci soliton equation in f(R, T)-gravity having anisotropic fluid. Also harmonic significance of Ricci soliton on anisotropic fluid spacetime in f(R, T)-gravity with a harmonic potential function is derived. We derive field equations for perfect fluid plane symmetric static spacetime and obtain their solutions. For each solution we then obtain Ricci soliton vector fields. We observe that such spacetimes admit expanding, shrinking or steady Ricci solitons. All the obtained solitons are trivial in nature. When these Ricci soliton vector fields become Killing vector fields then our results are in full agreement with the theorems deduced from our study.

Published: November 2023

Abstract
In the present report, ceramic specimens of sodium bismuth titanate [Na0.5(Bi1-xSmx)0.5TiO3] were prepared through solid-state reaction method with variations in the dopant concentrations specifically, x = 0.0, 0.1, 0.3, 0.5. The structural, optical, mechanical, and magnetic properties of lead-free NBT ceramics were investigated. The rhombohedral phase with space group R3c was confirmed in all prepared ceramic samples using X-ray diffraction patterns and Rietveld analysis. SEM micrographs and Energy Dispersive x-ray spectroscopy (EDAX) assess the morphology, grain size, overall structure, and stoichiometry of the developed compounds. FTIR spectroscopy was used for characterizing and identifying the functional groups. UV–vis spectroscopy revealed that band gap values decreased as dopant concentration increased, confirming the use of NBT-based perovskite as a photoactive material. PL spectra at room temperature exhibited reddish-orange emission. Colour coordinates and CCT values are in the range of 3483 K to 5912 K. At a concentration of x = 0.3, the materials displayed a high Vickers hardness of 8.20 GPa and exhibited minimal wear with low frictional coefficient values. Ferromagnetic behaviour at room temperature (RTFM) was detected in Sm-modified ceramic samples, as confirmed by the VSM study. The cumulative effect impact of the rare earth dopant cation at the Bi-site of NBT was widespread and demonstrated significant potential for use in optoelectronic devices.

Abstract
The S-box is a vital component for producing nonlinearity in a block cipher. Seldom this component is constructed through finite fields; however, sometimes Galois rings are used for its construction. In this work, we utilize the extended Galois ring to construct a Substitution box (S-box) over the ring

The designed S-box is generated by multiple elements and thus exhibits a high level of confusion compared to typical S-boxes. An encrypted color image is compared to existing encrypted S-box images to investigate their effects. First, we separate the distinct channels from a digital image and create 256-order matrices with 16-bit entries for each channel. We then apply the designed image encryption algorithm to these matrices. For the permutation step, we use the 1-dimensional logistic map to generate the key. Then, we apply the exclusive-or operation to all three layers of the image using the key. Finally, concatenate all these layers to create the encrypted image. The result is the proposal of a new RGB image encryption technique. The proposed encryption technique can replace several image encryption techniques that rely on S-boxes. In general, this technique aims to achieve optimal values.
A study on analytical solutions and conservation laws of the cgKP occurring in straits
Authors: Shukla Shitesh , Kumar Mukesh , Kumar Raj 
Published: November 2023

Abstract
The (2+1)-KP equation in its canonical generalized form i.e. cgKP relates to water waves that propagate exclusively in straits or rivers, as opposed to unbounded surfaces such as oceans. The cgKP, an example of a complex nonlinear system, is solved analytically in this article. To solve analytically the cgKP, the Lie symmetries are generated to get several novel invariant solutions to the cgKP, which are rare as far as the authors are aware. The cgKP reduces to an equivalent PDE with fewer independent variables than the original PDE. Animation profiles are utilized to better understand the obtained solutions, and they reflect transition from doubly solitons to single soliton; transition from negatons to positons and negatons; single solitons and multi solitons; annihilation of multi solitons; elastic parabolic profiles; single front parabolic and positons; multi-negatons on flat surface, and fusion of multi solitons wave types. Because of the presence of arbitrary functions in infinitesimal transformations, the Lie symmetry method has the potential to provide more variety in solutions. When compared to previously published findings, this study convincingly highlights the originality of the solutions. In the future, without assuming any relation among the arbitrary functions involved in infinitesimals, someone can explore the possibility of some more solutions. The physical character of the analytical results could help coastal engineers develop models of coastlines and ports in the current study.

Published: November 2023

Abstract
The present work elucidates the significant alterations in several physical characteristics of thermally evaporated TiPcCl2 thin films resulting from vacuum annealing at 373 and 473 K. The structure, surface morphologies, and molecular structure of TiPcCl2 thin films were studied using x-ray Diffraction (XRD), Transmission Electron Microscope (TEM), Field-Emission Scanning Electron Microscope (FESEM), and Fourier Transform Infrared (FT-IR). Results confirmed nanostructure attributes of as-deposited and annealed films, as well as the phase transition in TiPcCl2 was observed during annealing. The optical constants of as-deposited and annealed films in the wavelength range of 200–2500 nm were determined using spectrophotometric techniques. The indirect optical energy gap was observed to diminish with increasing annealing temperature due to enhanced crystallinity of thin films. Using the single oscillator model, the dispersion of the refractive index at normal dispersion was investigated. The third-order nonlinear susceptibility, χ(3), the nonlinear refractive index n2 and the nonlinear absorption coefficient, βc, were calculated and then discussed for both the as-deposited and annealed films. The electrical conductivity of TiPcCl2 exhibited increased as the temperature increased, suggesting its characteristic as a conventional organic semiconductor. The parameters of Mott’s model were obtained and discussed under low-temperature conditions afterward. Conclusions derived from this research indicate that the unique properties of vacuum annealing TiPcCl2 have great promise for future use in optoelectronic systems.

Published: November 2023

Abstract
Real time detection of time evolving growth rates of multiple stable magnetohydrodynamic (MHD) eigenmodes has been achieved in DIII-D tokamak experiments via multi-mode three-dimensional (3D) active MHD spectroscopy. The measured evolution of the multi-modes’ growth rates is in good accordance with the variation of the plasma β

N
. Using experimental equilibria, resistive MARS-F simulations found the two least stable modes to have comparable growth rates to those experimentally measured. Real time and offline calculations of the modes’ growth rates show comparable results and indicate that cleaner system input and output signals will improve the accuracy of the real time stability detection. Moreover, the shortest real time updating time window of multi-mode eigenvalues can be about 2 ms in DIII-D experiments. This real time monitoring of stable, macroscopic kink and tearing modes thus provides an effective tool for avoidance of the most common causes of tokamak disruption.

Abstract
The current study describes a novel, solvent-free, template solid-state synthesis of Zinc Oxide nanoparticles (NPs). The prepared sample was prepared by thermal decomposition route. The prepared sample was characterized by X-ray diffraction (XRD), Rietveld refinement, Field emissionscanningelectronmicroscopy (FESEM), Energy dispersive X-ray spectroscopy (EDX) and Ultra violet visible spectroscopy (UV-Vis). Singlephase crystalline structure of prepared NPs was confirmed using X-ray diffraction and the mean crystallite size of ZnO NPs was about 14nm. Rietveld refinement study,which yielded a good peak fitting between measured and calculated patterns. Chemical composition of the prepared sample was determined using EDX. The size and morphology were evaluated using FESEM which has almost spherical shapein the range of 6-35 nanometres. The optical properties of the as-prepared sample and their bandgap were determined using UV-Vis and it was calculated as 3.19 eV. These findings demonstrated that ethylene glycol (EG) inhibits nanoparticles for coagulate and results in the formation of homogeneous NPs with an optical bandgap of 3.19eV. This study represents an efficient thermal degradation synthesis process for the ZnO NPs with a broad range of potential applications.
