Abstract

The unveiling of superconductivity in La3Ni2O7-δ under pressure, following the suppression of a high-temperature density wave (DW) state, has attracted considerable attention. Notably, the nature of this competing DW order remains elusive, presenting a crucial question that demands further investigation. Here, we employ the muon-spin rotation/relaxation (μSR) technique combined with dipole-field numerical analysis to probe the magnetic response of La3Ni2O7-δ as a function of hydrostatic pressure. At ambient pressure, μSR experiments reveal commensurate static magnetic order below TN ∼ 151K. The comparison of the observed internal magnetic fields with dipole-field calculations reveals the magnetic structure's compatibility with a stripe-type arrangement of Ni moments (∼ 0.3-0.7μB), characterized by alternating lines of magnetic moments and non-magnetic stripes. Experiments under pressure (up to ∼ 2.3 GPa) demonstrate an increase of the magnetic ordering temperature at a rate dTN/dp ∼ 2.8 K/GPa. This trend is opposite in sign and significantly smaller in magnitude compared to the changes observed in the DW order of unknown origin reported by Wang et al. [arXiv:2309.17378]. Our findings reveal that the ground state of the La3Ni2O7-δ system is characterized by the coexistence of two distinct orders — the spin density wave and, most likely, charge density wave — with a notable pressure-induced separation between them.
Strategic Honeypot Allocation in Dynamic Networks: A Game-Theoretic Approach for Enhanced Cybersecurity

Published: February 2024

Abstract

Honeypots play a crucial role in implementing various cyber deception techniques as they can mislead attackers and divert them away from valuable assets. The topology of tactical networks changes over time due to the topographical environment and node mobility. An impactful strategic placement of honeypots in tactical networks should essentially consider not only network aspects but also attackers' preferences. To this end, we propose a game-theoretic approach that models an attack-defense scenario and develops an optimal honeypot allocation strategy for the defender. Our approach takes into consideration the changes in network connectivity and the specific features and criticality of different nodes. In particular, we introduce a two-player dynamic game model that explicitly incorporates the future state evolution resulting from changes in connectivity. The defender's objective is twofold: to maximize the likelihood of the attacker hitting a honeypot and to minimize the cost associated with deception in terms of the reconfiguration cost of honeypot re-allocation due to mobility. We present an iterative algorithm to find Nash equilibrium strategies. Unfortunately, this class of games suffers from the curse of dimensionality due to the size of the large state space. Therefore, we evaluate the scalability of our algorithm and provide a compact state space that shows a significant reduction in terms of runtime. Finally, we relax the assumption that the defender has full up-to-date knowledge of the network topology. We present a sensitivity-analysis-based approach to quantify the impact of imperfect information in terms of the defender reward. We validate our approach numerically via extensive simulations, demonstrating that our game model successfully enhances network security and is more scalable.

Published: February 2024

Abstract
This study delves into the mechanism of hydrogen adsorption and the impact of anode carbon deposition on the performance of solid oxide fuel cells (SOFCs). As a result, this article focuses on investigating methods to mitigate the adverse effects of carbon deposition in SOFCs through the utilization of molecular simulation techniques. Additionally, the article aims to explore the correlation between the hydrogen adsorption mechanism and cell performance, with the ultimate goal of enhancing SOFC efficiency. To accomplish these objectives, molecular simulations are employed to elucidate the reaction mechanism of carbon adsorption on the anode. This analysis also involves evaluating changes in diffusion coefficients under varying fuel mixtures and operating temperature. The findings reveal a noteworthy enhancement in the diffusion coefficient of mixed gases within the Au-doped Ni catalyst, showing an improvement of up to 45.46% at 973K. Furthermore, the electrical power generated by mixed gases in the Au-doped Ni catalyst at 973K demonstrates an increase of up to 12.06%.

Abstract
B lymphocytes may facilitate chronic inflammation through antibody production or secretion of cytokines, including lymphotoxin (LT)-a1b2 associated with development of lymphoid tissue. Tertiary lymphoid structures (TLS) characterize human and murine ileitis by suppressing outflow from the ileum. Here, we show that B cell-derived secretory IgA protected against ileal inflammation, whereas B cell-derived LTa guarded against ileitis-associated loss of body mass. We initially hypothesized this protection resulted from formation of TLS that suppressed lymphatic outflow and thereby restrained systemic spread of inflammatory signals, but B cell-selective deletion of LTb did not exacerbate weight loss, despite eliminating TLS. Instead, weight loss driven by the cachectic cytokine TNF was exacerbated when LTa3, another ligand for TNF receptors, was selectively neutralized. Thus, B cells’ multi-faceted impact on ileitis includes generating secretory IgA, expressing LTa1b2 to drive formation of TLS, and producing LTa3 for protecting against weight loss in the presence of TNF.

Authors: Li Cong , Wu Qiannan 
Published: February 2024

Abstract
A theoretical investigation and simulation of a terahertz metasurface refractive index sensor composed of graphene-metal is presented in this article. The analysis and evaluation of the reflector's performance is conducted through the implementation of the frequency-domain finite-difference method. The transmission and reflection spectra are analyzed in order to identify the characteristic dimensions that can enhance both sensitivity and reflectivity by optimizing the material's thickness, cycle duration, and width of the etching structure. The findings indicate that the sensor exhibits a quality factor of 8.4 and a maximal refractive index sensitivity of 1.48 THz/RIU within the operating frequency range of 0.1-2.0 THz. These values are three times greater than those of the conventional sensor. The design of this refractive index sensor has the potential to revolutionize bioassays pertaining to the quantification of proteins, viruses, cancer cells, and their markers.

Abstract
Background: Long-lasting insecticidal nets (LLINs) are the primary method used by the National Malaria Control Program (NMCP) to combat malaria. However, malaria vector resistance poses a serious threat to the success of vector control measures. The objective of this study was to analyze the current state of malaria vector resistance to commonly used insecticides in northern sentinel sites of Cote d’Ivoire.
Methods: Anopheles larvae were sampled in Bouna, Korhogo, and Odienné. Adult females aged 2-5 days were subjected to various susceptibility tests according to the protocol recommended by the World Health Organization (WHO). Metabolic resistance was demonstrated by pre-exposure of mosquitoes to Piperonyl butoxide (PBO). Other insecticides such as Chlorfenapyr and Clothianidin were tested in anticipation of Indoor Residual Spraying (IRS) as a complementary vector control method in these areas. Anopheles gambiae s.l. complex subspecies were identified by polymerase chain reaction (PCR).
Results: Resistance to pyrethroids, the fundamental chemical for treating LLINs, was strongly confirmed in the sentinel sites. Synergist tests demonstrated an increase in the mortality rate and restored susceptibility of malaria vectors after pre-exposure to Piperonyl butoxide (PBO). Identification of resistance mechanisms showed the presence of kdr-West and Ace-1 genes. Among these genes, kdr-West was found to be the most prevalent in the Anopheles gambiae population of Bouna (96%), Korhogo (98%), and Odienne (100%).
Mosquitoes exhibited sensitivity to chlorfenapyr at a dose of 100 µg/bottle and 200 µg/bottle. However, mosquitoes showed resistance to clothianidin in each site, except for Odienné, where vectors were susceptible to this insecticide.
Conclusions: The resistance of malaria vectors to commonly used insecticides is strongly confirmed in the savanna zone of northern Côte d'Ivoire. Resistance markers in this region are heterogeneous and the intensity of resistance could vary according to the ecological context of the sites. Chlorfenapyr emerges as a promising option for IRS programs, given its efficacy and absence of resistance observed in this study. Surveillance of insecticide resistance need to be continued to guide the selection of appropriate control measures.

Abstract
Purpose: To develop a novel method to simultaneously obtain the structural and functional characteristics of the brain extracellular space.
Materials and Methods: Design and develop a magnetic tracing imaging analysis method compatible with impedance measurement using Michigan electrodes, synchronously obtaining brain extracellular space structural and electrical characteristic parameters. Twelve adult Sprague-Dawley rats were randomly divided into two groups: the first group was tested using traditional magnetic tracing techniques (n=6), while the second group was tested with a magnetic tracing detection system compatible with impedance measurement applied (n=6). Parameters such as diffusion coefficients, volume fraction and electrical characteristic parameters were calculated and compared. Visualisation of the tissue fluid drainage process was also conducted.
Results: The system can synchronously obtain structural and impedance characteristic parameters of extracellular molecular diffusion in the mouse brain. The comparison results show a decrease in the molecular diffusion coefficient in the extracellular gaps (t=4.748, P＜0.01) and a reduction in the diffusion rate and volume fraction of extracellular gaps (t=7.77, P＜0.01). Additionally, electrical parameters of the extracellular gaps were measured, with a conductivity of 2.006 S/m, a dielectric constant of 84.77, a calculated diffusion rate of 3.54*10-4mm2/s, and a volume fraction of 17.43%, consistent with the data obtained from the magnetic tracing method.
Conclusion: This system can simultaneously acquire the structural and functional characteristics of ECS, laying the foundation for a new method of neural regulation through the ECS pathway.

Abstract
In present study, twenty different wheat varieties were evaluated for various agronomic traits including plant height, number of tellers per plant, leaf area index, spike length, number of spikelets per spike, number of grains per spike, peduncle length, chlorophyll index, thousand-grain weight, grain yield, and biological yield at the research area of Agronomy, Hafiz Abad Research Station, College of Agriculture B.Z.U. Bahadur Campus Layyah during crop season 2020-2021 and 2021-2022. The study was designed following RCBD (Randomized Complete Block Design) with 3 replications of each treatment. Each plot in the study was 4 meters in length and 5 meters in width. The wheat genotypes that were evaluated exhibited significant variability for all of the attributes under investigation. Grain yield was significantly correlated with the spike length, number of spikelets per spike, plant height, 1000-grain weight, number of grains per spike and flag leaf area. Multivariate analysis showed that 20 different wheat varieties formed 3 different clusters. Cluster-1 showed maximum mean values for yield and yield-related attributes compared with cluster-2 and cluster-3. The genotypes accounted for 95% of the total variation in grain yield and associated characteristics, accounting for a significant proportion of the overall differences. In general, the results of this study showed that genotypes like FSD-08, Ujala-16, Fakhr-e-Bhakhar-19, and Akbar-19 have the highest yield potential when grown in the semi-arid climate of Layyah, Pakistan. Thus, all these genotypes were suggested for general cultivation in arid conditions of district Layyah.

Published: February 2024

Abstract
A new hybrid containing alkali metal-organic framework and polymeric iodoargentate, {[K(bpdo)2](AgI2)}n (1) (bpdo = 4,4'-dipyrdiyl-N,N'-dioxide) has been synthesized by solution process and structurally determined, which is the first potassium-based 3-D network constructed from linear bpdo ligands and also serves as host for accommodating 1-D polymeric (AgI2)nn− chains. The 3-D [K(bpdo)2]nn+ metal-organic framework can be described as the result of bridged [K(bpdo)2]nn+ 2-D sheets by KO8 square antiprisms, in which electrostatic interaction among bpdo ligands solidifies this network. The straight-linear (AgI2)nn− is constructed from edge-sharing of AgI4 tetrahedra, which is accommodated in the channels of 3-D [K(bpdo)2]nn+ network. This hybrid is a semi-conductor with optical gap of 2.80 eV. Besides, 1 exhibits effective and repeatable photocurrent responses with current density of 1.40×10− 7 A, and the photocurrent response mechanism was also discussed.

Background：The prevention of myopia in adolescents has become a focus of public health in the world, and the important role of eye health behaviors in the prevention and control of myopia in children and adolescents is further clarified by analyzing the risk factors related to myopia.Methods:From September to November 2021, a total of 16,464 primary and secondary school students aged 6 to 18 in Baotou City were selected for vision screening, refractive check, and a questionnaire survey of myopia-related factors using stratified cluster sampling.Results：Among the primary and secondary school students, the myopia rate was 56.1%, the hyperopia rate was 11.0%, the astigmatism rate was 39.5%, and the rate of high myopia was 6.3%. The myopia rate was higher in urban areas (57.12%) than in suburban areas (55.17%) and higher in girls (59.52%) than in boys (52.81%). Multifactorial logistic regression analysis showed that risk factors for myopia included being male, having high BMI, having one or both parents with myopia, spending more than one-hour doing homework at home, doing close work for more than one hour, and frequent or always reading while lying down. Doing eye exercises once a day or more and sleeping more than eight hours were protective factors for myopia.Conclusions:The prevalence of myopia among primary and secondary school students in Baotou City is high, and myopia is affected by a combination of factors such as education stage, genetics, eye habits, and eye environment, so effective interventions should be taken to prevent myopia in children and adolescents.
Optimizing Merger Targets in the Banking Industry: A Stochastic Approach using Inverse Data Envelopment Analysis and Goal Programming

Published: February 2024

Abstract
This paper presents a new approach to address target setting in mergers by utilizing two complementary techniques: Goal Programming (GP) and Inverse Data Envelopment Analysis (InvDEA). Traditional DEA models assess the relative efficiency of decision-making units (DMUs) based on multiple inputs and outputs. However, InvDEA focuses on determining the input and output quantities required to achieve a specific efficiency score target. These models face limitations when deviations from the frontier occur due to noise and random errors in the data. To overcome this issue, this paper introduces a novel stochastic method that estimates the input/output levels of the merged unit needed to attain the predetermined efficiency score at a specified level of significance (α ∈ [0, 1]). Our models proposed are applied to the banking industry, demonstrating their effectiveness. The study provides decision makers with a valuable method to incorporate their preferences when setting merger targets, enabling them to optimize savings in specific inputs or maximize the production of desired outputs. To validate the proposed method, an illustrative application is conducted within the banking industry.

Published: February 2024

Abstract
This paper reviews the utilization of Gold Ore Tailings (GOTs) in manufacture of Geopolymer Concrete (GPC) along with Recycled Coarse Aggregates (RCAs). The paper also highlights the workability and mechanical properties of GPC. The results of the study demonstrated that the slump value of GPC samples was 35.1 mm for 15% replacement of GOTs to River Sand (RS) which was lower than that of Conventional Concrete (CC2) samples (i.e., 110 mm). The compressive strength, split tensile strength, and flexural strength of GPC samples were 47.8 MPa, 5.01 MPa and 6.98 MPa, respectively and these results were better when compared to CC2samples (i.e., compressive strength of 47.4 MPa, split tensile strength of 4.4 MPa and flexural strength of 4.89 MPa). The statistical analysis was conducted to predict the experimental results in which R2 values of developed model for compressive strength, split tensile strength, and flexural strength was 70%, 85.5%, and 89%, respectively. The Field Emission Scanning Electron Microscopy (FESEM) analysis of GPC samples observed development of rod-like ettringite, which makes the GPC paste more compact and denser. Finally, the cost analysis was done to know the economic feasibility of optimum mix of raw materials utilized for the manufacture of GPC and CC2. It was found that the cost of GPC was 38.20% more than that of CC2.
A hybrid PKPD agent-based model of the tumour immune interaction: effects of anti-cancer combination therapy
Authors: Truong Van Thuy , Yates James , Vicini Paolo , Dubois Vincent , Lythe Grant 
Published: February 2024

Abstract
We have developed a three dimensional hybrid multi-scale agent-based ODE PDE model including tumour immune interaction, cell cycle phases, oxygen and drug diffusion dynamics, the pharmacodynamics of chemotherapy, targeted therapies, immunotherapy, radiotherapy and the respective systemic exposure levels of pharmacological treatments (described by pharmacokinetic modelling). The aim of this model is to support a more detailed understanding of the spatial-temporal dynamic interactions between cancer cells, the relevant immune cells, and especially targeted therapies' molecular moieties, which are all expected to interact simultaneously in the tumour microenvironment. This interaction can then be further investigated in the context of combination therapies, thus making some inroads in the mechanistic understanding of positive and negative synergies when multiple therapies are administered within this complex system. The key scientific question this work addresses is the role of temporal sequencing in combination therapies, which require the simultaneous modelling of many relevant components of the system to be properly understood.
A second-order scheme with nonuniform time grids for the two dimensional time-fractional Zakharov-Kuznetsov equation
Authors: Chen Lisha , Wang Zhibo 
Published: February 2024

Abstract
In this paper, we investigate the numerical method for the two dimensional time-fractional Zakharov-Kuznetsov equation. By the method of order reduction, the model is first transformed to an equivalent system. A nonlinear difference scheme is then proposed to solve the equivalent model, with min{2, rα}-th order accuracy in time and second-order accuracy in space, where α ∈ (0, 1) is the fractional order and the grading parameter r ≥ 1. The existence of the numerical solution is carefully studied by the renowned Browder fixed point theorem. With the aid of Grönwall inequality and some crucial skills, we analyze the unconditional stability and convergence of the proposed scheme based on the energy method. Finally, numerical experiments are given to illustrate the correctness of our theoretical analysis.
