Unlocking the Dynamic Impact of Economic and Non-Economic Factors on Tourism Demand in BRICS Economies
Authors: Alam Mir , Hussain Jamal , Kiran Faiza 
Published: March 2024

Abstract
In recent decades, economic and non-economic factors have significantly shaped tourism demand, affirming attention from researchers and policymakers. This study employs advanced econometrics techniques, including cross-sectional dependency, slope homogeneity, unit root, cointegration and long-run estimation, to explore the impact of economic determinants (world GDP per capita, exchange rate, interest rate, and relative price) and non-economic factors (political stability and climate change) on tourism demand in BRICS economies from 1996 to 2022. Findings indicate that exchange rates, interest rates, political stability, and world GDP per capita positively influence tourism demand, while climate change and relative price negatively impact it. Moreover, bidirectional causality exists between world GDP per capita and tourism demand, and one-way causation is observed for exchange rate, relative price, and political stability. In conclusion, the economic determinants significantly impact tourism demand more than non-economic factors. The study provides policy guidelines for enhancing tourism demand.
Improving Many-Objective Optimization via An Adaptive Penalty Scheme and Jaya Operator in the MJaya/D Algorithm

Published: March 2024

Abstract

Achieving an effective balance between solution convergence and diversity remains a key challenge when solving multi-objective optimization problems. However, the performance of existing algorithms continues to degrade on many-objective optimization problems. Additionally, the genetic operators commonly utilized in many-objective evolutionary algorithms require extensive tuning of control parameters, without which solution quality suffers. To address these limitations, several new techniques are proposed. First, an adaptive penalty mechanism that leverages population and weight vector distribution information to assign specialized penalty factors to each sub-problem is developed by us. Second, the Jaya optimization algorithm is extended by us to improve its efficacy in many-objective spaces. Finally, Levy mutation is incorporated to help escape local optima and enhance population diversity. The proposed MJaya/D algorithm is assessed on standard DTLZ benchmark problems to evaluate the performance improvements stemming from the Jaya operator and adaptive penalty scheme. Experiments demonstrate that MJaya/D obtains superior Pareto front approximations compared to current state-of-the-art techniques for several many-objective optimization formulations.
Improved discrete particle swarm optimization using Bee Algorithm and multi-parent crossover method (Case study: Allocation problem and benchmark functions)
Authors: Zibaei Hamed , Mesgari Mohammad Saadi 
Published: March 2024

Abstract

Compared to other techniques, particle swarm optimization is more frequently utilized because of its ease of use and low variability. However, it is complicated to find the best possible solution in the search space in large-scale optimization problems. Moreover, changing algorithm variables does not influence algorithm convergence much. The PSO algorithm can be combined with other algorithms. It can use their advantages and operators to solve this problem. Therefore, this paper proposes the onlooker multi-parent crossover discrete particle swarm optimization (OMPCDPSO). To improve the efficiency of the DPSO algorithm, we utilized multi-parent crossover on the best solutions. We performed an independent and intensive neighborhood search using the onlooker bees of the bee algorithm. The algorithm uses onlooker bees and crossover. They do local search (exploitation) and global search (exploration). Each of these searches is among the best solutions (employed bees). The proposed algorithm was tested on the allocation problem, which is an NP-hard optimization problem. Also, we used two types of simulated data. They were used to test the scalability and complexity of the better algorithm. Also, fourteen 2D test functions and thirteen 30D test functions were used. They also used twenty IEEE CEC2005 benchmark functions to test the efficiency of OMPCDPSO. Also, to test OMPCDPSO's performance, we compared it to four new binary optimization algorithms and three classic ones. The results show that the OMPCDPSO version had high capability. It performed better than other algorithms. The developed algorithm in this research (OMCDPSO) in 36 test functions out of 47 (76.60%) is better than other algorithms. The OMPCDPSO algorithm used many parts of the best solution. It put them in the multi-parent crossover and neighborhood search with onlookers. This made it better than DPSO. The Onlooker bees and multi-parent operators significantly impact the algorithm's performance.

Published: March 2024

Abstract
This paper studies the chaos synchronization of the modified circular restricted three-body problem(MCR3BP) using sliding mode control technique. The MCR3BP incorporates the presence of three-body interactions parameter of the primaries. We have investigated two identical systems of the MCR3BP known as master and slave systems taken at transmitter and receiver ends, respectively. In order to synchronize two identical systems of the MCR3BP a sliding mode control technique have taken into account. An error dynamical system has investigated between the master and slave systems. The stability properties for chaos synchronization of two identical systems are investigated through Lyapunov stability theory. It is concluded by the Lyapunov stability theory the error dynamical system is stable. There is no need to calculate the Lyapunov exponents because the sliding mode control technique is very effective and convenient to achieve the synchronization between two identical systems of the MCR3BP. It is observed that all the included parameters have significant impacts on the trajectory of the dynamical systems of the MCR3BP. Finally, the importance of the designed sliding mode control technique for MCR3BP has revealed by the numerical simulation.
In-situ Observation and Discrete Element Simulation of Powder Lubrication Mechanism at Different Slip Velocities and Loads

Published: March 2024

Abstract
In this paper, the powder lubrication layer composed of graphite particles was prepared by spray method and the effect of velocity and load on the friction characteristics of graphite layer was investigated using a friction tester that can observe the friction interface in real time. Subsequently, 3D surface profilometer, SEM, and EDS were used to characterize the morphology and elements of worn surfaces. The friction results show that at low slip velocity (5 mm/s) and lower load (4N), only partial powder lubrication layer was formed in contact interface, the surface of the graphite layer exhibited obvious peeling characteristics. When slip velocity is too fast (20 mm/s), the dissipation of powder layer increases and the metal substrate is exposed, while there are serious abrasions and chip exfoliation. At the velocity of 12.5 mm/s, the graphite layer shows the best lubrication effect, and the worn surface is more flat compared with that of applying other velocities. The coordination number, the total number of force chains and high stress particles inside the graphite layer during friction process were calculated using the discrete element method at different velocities. With heavy load (8N) that dense force chains are formed at the interface. But the powder layer is easily damaged throughout that the substrate contact directly, thus the powder layer of interface is unevenness extremely. Trying to provide a reasonable explanation for the inherent mechanism of the influence of velocity and load on the lubrication effect of the powder layer.

Published: March 2024

Abstract
Background
Chronic Myeloid Leukemia (CML) is a myeloproliferative neoplasm characterized by the presence of the Philadelphia chromosome (Ph), resulting from the t(9;22)(q34;q11.2) translocation. Imatinib, a tyrosine kinase inhibitor, has revolutionized the treatment of CML. However, despite the initial response, some patients may progress to an advanced stage, such as a blast crisis.
Case Presentation:
We report a 40-year-old female who presented with CML chronic phase taking imatinib 400 mg/day and achieved a complete hematological response (CHR) after one month of treatment. She achieved suboptimal response in the third month (BCR-ABL positive 10.29% IS). However, five months into therapy, she developed a sudden lymphoid blast crisis with chromosomal aberrations involving chromosome 10 and 12. Molecular analysis detected concomitant L248V with partial exon 4 deletion and E225V mutations within the BCR-ABL1 fusion gene. The patient received intensive chemotherapy and dasatinib.
Conclusion
We report the first case of concomitant mutation of L248V with partial exon 4 deletion and E255V on BCR-ABL1 gene mutation which contributes to a sudden precursor B-cell lymphoid blast crisis.
Utilizing dry heating Maillard reaction approach to modify the functional and structural properties of sunnhemp protein isolate-dextran conjugates
Authors: Rawat Rashmi , Saini Charanjiv Singh 
Published: March 2024

Abstract
Sunnhemp protein isolate (SHPI) was prepared by utilizing alkaline extraction acid precipitation method. SHPI-dextran conjugates (1:1 w/w ratio) were prepared by dry heating method with Maillard reaction at 60°C for 0, 1, 3, 5, 7, and 9 days of incubation at 79% relative humidity. The functional properties of SHPI-dextran conjugates like solubility, emulsifying, foaming, water and oil binding capacities, dispersibility, and gelation were improved as compared to pure SHPI. Increment in browning index values of SHPI-dextran conjugates were observed with increase in Maillard reaction time. Conjugated SHPI reduced the percentage of α-helix and increased the content of β-sheet, β-turn and random coils content. FTIR spectroscopy confirmed the formation of covalent bonds between SHPI and dextran via Maillard reaction. XRD analysis indicated both semicrystalline and amorphous structure of SHPI-dextran conjugates as the incubation time was increased from 0 to 9 days. Decreasing trend in the values of surface hydrophobicity values were found with increase in incubation time. Free and total sulfhydryl content of SHPI was increased after conjugation with dextran up to 5 days and thereafter decreased. Incubation time of five days at 60°C and 79% RH was optimized on the basis of improvement in functional characteristics and extent of Maillard reaction time. Overall, the present study showed that conjugation of sunnhemp protein isolate with dextran successfully improved the functional characteristics of SHPI.

Abstract

The discovery of Mn-Ca complex in photosystem II stimulates research of manganese-based catalysts for oxygen evolution reaction (OER). However, conventional chemical strategies face challenges in regulating the four electron-proton processes of OER. Herein, we investigate alpha-manganese dioxide (α-MnO2) with typical MnIV-O-MnIII-HxO motifs as a model for adjusting proton coupling. We reveal that pre-equilibrium proton-coupled redox transition provides an adjustable energy profile for OER, paving the way for in-situ enhancing proton coupling through a new "reagent"— external electric field. Based on the α-MnO2 single-nanowire device, gate voltage induces a 6-fold increase in OER current density at 1.7 V versus reversible hydrogen electrode. Moreover, the proof-of-principle external electric field-assisted flow cell for water splitting demonstrates a 34% increase in current density and a 44.7 mW/cm² increase in net output power. These findings indicate an in-depth understanding of the role of proton-incorporated redox transition and develop practical approach for high-efficiency electrocatalysis.
