Authors: Zhang Yan , Gao Shujing , Wang Huatao , Liu Yang 
Published: September 2023

Abstract
Citrus Huanglongbing (HLB) epidemic diseases is a destructive threat to the citrus industry worldwide. In this paper, a stochastic epidemic model is proposed for the transmission of Huanglongbing in scenarios between Asian citrus psyllid and the citrus trees host. The influence of insecticide resistance is considered and the dynamical properties of the new model are mathematically analyzed. It is proved that the model is well-posed by obtaining the existence of a single global positive solution. Further, when R
2 > 1, weak persistence in the mean is obtained by developing a suitable Lyapunov function and sufficient criteria R
1 < 1 is derived for the extinction of the disease. Moreover, the analysis of stochastic optimality is used, and a proper strategy is studied to provide a theoretical basis for the prevention and control of HLB. Numerical simulations and examples are carried out to verify the main theoretical results.

Published: September 2023

Abstract
We investigate the thermoelectric transport and conversion of a parallel-coupled double quantum dot system, which consisting of two capacitively coupled quantum dots in the Coulomb-blockade regime. We found that the system exhibits an unconventional thermoelectric conversion process induced by the inverse current effect, which is attributed to the increased Coulombic interaction between quantum dots, resulting in strong asymmetry in the system. We study the transport properties of steady-state particle current and heat current, and analyze the influence of Coulomb interaction on the thermodynamic characteristics of unconventional thermoelectric heat engines and refrigerators.

Abstract
Computed tomography (CT) is a widely used nondestructive testing (NDT) technique for material research, paleontology research and other fields. However, it is difficult for CT to reconstruct flat objects at high magnification ratios. Computed laminography (CL) enables high-resolution imaging for flat objects due to its unique scanning geometry. A challenging task for CL image reconstruction is to deal with the cross-section artifacts resulting from the incomplete projection data acquired from the CL scan. An effective multi-scale fusion reconstruction algorithm of CT and CL was proposed in this paper. The algorithm combining the advantages of the two scanning geometries, low-resolution CT data was used to compensate for the data missing in CL projection domain, and the cross-section artifacts were reduced. Experiments on paleontological fossils and multilayer printed circuit boards (PCB) were performed, where CT and CL data from different systems and scanning conditions. The results showed that the method can effectively suppress the cross-section artifacts of CL and obtain high-resolution reconstructed images.
Novel Optical bi-directional solutions to the new dual-mode derivative nonlinear Schrödinger equation
Authors: Alam Badar E , Javid Ahmad 
Published: September 2023

Abstract
In recent times, a novel category of nonlinear physical models known as dual-mode nonlinear equations has emerged. These equations include various real-valued dual-mode equations linked to widely-known single-mode equations like KdV, mKdV, Schrödinger and Burger’s. Extensive research has been conducted to establish and investigate these equations. This study presents a novel dual-mode derivative nonlinear Schrödinger equation that incorporates new parameters for dissipative effects, nonlinearity, and interaction phase velocity. Various methods such as the tanh-coth scheme, extended exponential method, Kudryashov-scheme and the sine-cosine function methods are employed to investigate the solutions of the model. The obtained solutions are illustrated through graphical 2D and 3D and to demonstrate their dynamics and shapes. Furthermore, the interaction of the dual-waves is correlated with changes in the phase-velocity parameter. This model describes propagation of two simultaneously directional waves instead of as in standard Schrödinger equation. For the propagation of solitons in nonlinear optics, the solutions found in this study have important significance. All the resulting solutions can help to comprehend the underlying mechanisms for numerous nonlinear phenomena in diverse domains, including nonlinear optics, plasma physics, Bose–Einstein condensates and others.
Energy bands in a three dimension simple cubic lattice of contact potential
Authors: Zhang Yi-Cai , Zhang J M 
Published: September 2023

Abstract
In this work, we investigate energy bands in a three dimensional simple cubic lattice of contact potential. The energy bands in the first Brillouin Zone are obtained with Ewald’s summation method. In comparison with single point potential, the presence of lattice potential changes the existence condition of negative energy states near zero energy. It is found that the system always has negative energy states for an arbitrarily weak periodic potential. In addition, we prove that if an irreducible unitary representation is not a trivial representation of group of wave vector, the corresponding wave functions at lattice sites would be zero. With this theorem, the degeneracy of energy bands is explained with group theory. Furthermore, we find that there exists some energy bands which are not affected by the lattice potential. We call their corresponding eigenstates as dark states. The physical mechanism of the dark states is explained by explicitly constructing the standing wave-type Bloch wave functions.

Abstract
In this article, a chain-shaped photonic crystal-based ring resonator (PhCRR), which can function as a channel drop filter (CDF), is designed using two-dimensional photonic crystals. Silicon rods with a refractive index of 3.44 are chosen, and they are perforated in the air with a refractive index of 1 for the PhCRR layout design. Silicon material is selected for realizing the PhCRR-based channel drop filter because it exhibits nearly zero absorption in the C-band (1530–1565 nm) spectral region. The PhCRR structure is established within two-dimensional hexagonal lattices. Transmission efficiency, quality factor, and sensitivity are critical parameters in the design of optical components. Our proposed ring resonator achieves a transmission efficiency of 99.7% with a quality factor of 4550 at a wavelength of 1551 nm. To analyze the drop filter’s functionality, we calculate the electric field distribution of two-dimensional photonic crystals at 1551 nm and 1553 nm. We employ the FDTD numerical analyser to extract simulation results, and the plane wave expansion solver method is used to estimate the photonic band gap of the designed resonator. The chain-shaped photonic crystal-based ring resonator is designed to operate in the third optical window wavelength, which offers very low loss (less than 0.2 dB). The proposed PhCRR is designed to operate within the conventional band range of 1530 to 1565 nm and can be used for various applications such as tunable add/drop multiplexing, optical filters, signal routing and switching in CWDM applications, free space communication systems, and photonic integrated circuits.

Abstract
A Cu-SnO2/ZnO nanocomposite was prepared using a single-step facile synthesis method, sol–gel, for photocatalyst application. The XRD of Cu-SnO2/ZnO nanocomposite shows SnO2 and ZnO have tetragonal rutile and hexagonal wurtzite, which is similar to HRTEM and SAED data. The crystallite sizes of SnO2, ZnO, Cu-SnO2, SnO2/ZnO, and Cu-SnO2/ZnO are 8.50 nm, 29.12 nm, 7.10 nm, 6.42 nm, and 3.50 nm, respectively. The calculated energy band gap of SnO2, ZnO, Cu-SnO2, and Cu-SnO2/ZnO from the DRS measurements is 3.60 eV, 3.20 eV, 3.34 eV, 3.48 eV, and 3.09 eV, respectively. The photoluminescence spectroscopy shows that Cu-SnO2/ZnO nanocomposite has a higher defect density than another sample. The Fourier Transform Infrared (FTIR) spectroscopy identifies the functional groups of the Cu-SnO2/ZnO powder samples. The EDS spectra of the synthesized Cu-SnO2/ZnO nanocomposite indicated the existence of the elements of Cu, Sn, Zn, and O, respectively. The photocatalyst activities of Cu-SnO2/ZnO have higher efficiency, ~78%, than other samples.
Ferrimagnetic, antiferromagnetic and ferromagnetic properties in triangle multi-layer graphene nanoflake
Authors: Ghasemifard Alireza , Panahi S F K S , Sharifian Mahmoodreza 
Published: September 2023

Abstract
The electronic and magnetic properties of vertically stacked multilayer triangular graphene nano-flakes with zigzag edges are studied using the first nearest neighbor tight-binding model combined with a single π-orbital Hubbard model, and compared with density functional-based tight-binding calculations. Magnetic ordering in the ground state is layered dependence. AA-stacking with odd and even numbers of layers offers ferrimagnetic and antiferromagnetic ordering, respectively. While AB-stacking always displays ferromagnetic ordering. Besides, the spatial distribution of the states in AAA stackings determines two distinct edge states where the zero energy states in the tight-binding spectrum have no probability of being localized on the middle layer, while non-zero states are widespread in all three layers.

Abstract
We have investigated the boson sector in an extended standard model (SM) with additional U(1)
D
symmetry. In the proposed model, the singlet scalar and doublet scalar Higgs are added in addition to the SM-like scalar Higgs. These scalars are also coupled to the gauge boson fields. In this work, we calculate the masses of both gauge and scalar Higgs bosons. Their masses are obtained through spontaneous symmetry breaking using the Higgs fields with non-zero vacuum expectation values. We also study numerically the positivity conditions of the vacuum expectation value of the scalars. In particular, we perform scanning of the parameter space of the potential and study the obtained scalar mass dependence on the parameter of the model.
Studying the impact of interface roughness on a layered photonic crystal as a sensor
Authors: Zaky Zaky A , Al-Dossari M , Hendy Ahmed S , Aly Arafa H 
Published: September 2023

Abstract
This study investigates the impact of the interface roughness on a layered photonic crystal as a gas sensor based on Tamm resonance in the terahertz range. The well-known transfer matrix method is used for simulation. The sensor's performance is observed for various thicknesses of the rough layer (exponential-graded refractive index layer) between the adjacent layers. The rise in the rough layer between adjacent porous and cavity layers causes a decrease in sensitivity but enhances the quality factor and figure of merit of the proposed structure. However, the change in the thickness of the rough layer between the metallic and the last cavity layer does not affect the performance.

Published: September 2023

Abstract
Here, we report the unusual behavior of an ytterbium-doped fiber laser with a low-Q-factor cavity characterized by a variety of qualitatively different regimes arising as a result of increasing pump power: from amplified spontaneous emission via self-induced laser line sweeping and self-Q-switching, to narrow-band ‘thermal-light’ emission. Special attention is paid to a discussion of the statistical and coherent properties of light released by the laser system in the considered operational regimes.

Abstract

Objective. Brain-computer interface (BCI)-controlled functional electrical stimulation (FES) could excite the central nervous system to enhance upper limb motor recovery. Our current study assessed the effectiveness of motor and prefrontal cortical activity-based BCI-FES to help elucidate the underlying neuromodulation mechanisms of this neurorehabilitation approach. Approach. The primary motor cortex (M1) and prefrontal cortex (PFC) BCI-FES interventions were performed for 25 min on separate days with twelve non-disabled participants. During the interventions, a single electrode from the contralateral M1 or PFC was used to detect event-related desynchronization (ERD) in the calibrated frequency range. If the BCI system detected ERD within 15 s of motor imagery, FES activated wrist extensor muscles. Otherwise, if the BCI system did not detect ERD within 15 s, a subsequent trial was initiated without FES. To evaluate neuromodulation effects, corticospinal excitability was assessed using single-pulse transcranial magnetic stimulation, and cortical excitability was assessed by motor imagery ERD and resting-state functional connectivity before, immediately, 30 min, and 60 min after each intervention. Main results. M1 and PFC BCI-FES interventions had similar success rates of approximately 80%, while the M1 intervention was faster in detecting ERD activity. Consequently, only the M1 intervention effectively elicited corticospinal excitability changes for at least 60 min around the targeted cortical area in the M1, suggesting a degree of spatial localization. However, cortical excitability measures did not indicate changes after either M1 or PFC BCI-FES. Significance. Neural mechanisms underlying the effectiveness of BCI-FES neuromodulation may be attributed to the M1 direct corticospinal projections and/or the closer timing between ERD detection and FES, which likely enhanced Hebbian-like plasticity by synchronizing cortical activation detected by the BCI system with the sensory nerve activation and movement related reafference elicited by FES.

Abstract
As part of the Snowmass'21 community planning excercise, the
Advanced Accelerator Concepts (AAC) community proposed future linear
colliders with center-of-mass energies up to 15 TeV and
luminosities up to 50 × 1034 cm-2 s-1 in a
compact footprint. In addition to being compact, these machines must
also be energy efficient. We identify two challenges that must be
addressed in the design of these machines. First, the Beam Delivery
System (BDS) must not add significant length to the accelerator
complex. Second, beam parameters must be chosen to mitigate
beamstrahlung effects and maximize the luminosity-per-power of the
machine. In this paper, we review advances in plasma lens technology
that will help to reduce the length of the BDS system and we detail
new Particle-in-Cell simulation studies that will provide insight
into beamstrahlung mitigation techniques. We apply our analysis to
both e
+
e
- and γγ colliders. The challenges and
solutions described in this paper are considered independently. A
unified, self-consistent concept for a BDS system for a 15 TeV
linear collider will be the subject of future work.

Abstract
The Majorana Demonstrator was a search for neutrinoless double-beta decay (0νββ) in the 76Ge isotope. It was staged at the 4850-foot level of the Sanford Underground Research Facility (SURF) in Lead, SD. The experiment consisted of 58 germanium detectors housed in a low background shield and was calibrated once per week by deploying a 228Th line source for 1 to 2 hours. The energy scale calibration determination for the detector array was automated using custom analysis tools. We describe the offline procedure for calibration of the Demonstrator germanium detectors, including the simultaneous fitting of multiple spectral peaks, estimation of energy scale uncertainties, and the automation of the calibration procedure.
Comparison Assessment of Pier Dimension Measurement with Different Terrestrial Laser Scanner (TLS) Setup Location
Authors: Syafuan Wan Mohamed , Ismail Neza , Efandi Daniel 
Published: September 2023

Abstract
A bridge is a structure that joins two highways and has four distinct parts: the deck, abutment, pier, and joist. For safety reasons, this structure required routine inspections by a qualified inspector. Suggesting a new approach that uses non-contact testing technologies (NCT) will resolve all the difficulties related to the inspector’s current conventional method’s increased time, expense, and labor intensity. Compared to traditional approaches using visual inspection, NCT technologies are prospective instruments for assessing the state of bridges since they allow for quick and simple measurement with little disruption to traffic. Terrestrial Laser Scanner (TLS) is now taught in surveying courses to help surveyors perform their jobs more efficiently. The goal of this study was to make technology use better because it requires less human interaction with quality results. TLS contains a points cloud consisting of x, y, and z coordinates; hence it can produce 3-dimensional (3D) model output. The main objective of this study is to produce the 3D model from point cloud data, followed by the second objective, which is to compare measurement of pier dimension with various distance of TLS setup distance location. To achieve this objective, configuration of TLS with Zig Zag setup location to cover all of bridge structure to produce a 3D model and configure three various distance TLS setup location to measure the accuracy of pier dimension. The control actual data was done by measuring using Total Station and measuring tape. The output of point cloud data from TLS using Cyclone Register360 was compared with actual data. The results shown point cloud data from TLS can produced 3D model with accurate dimension measurement. Setup the TLS location depends on the suitability of the work to increase the quality of data.
Comparison of MyRTKnet Performance with Various Real-Time Corrections Based on Different Time

Published: September 2023

Abstract
Virtual Reference Station (VRS), Master-Auxiliary Corrections (MAX), Individualised Master-Auxiliary Corrections (IMAX), Nearest Base, and Network D-GNSS are among the Network Real-Time Kinematic (NRTK) techniques supported by the Malaysia Real-Time Kinematic GNSS Network (MyRTKnet) in providing network-based solutions to users. However, different network corrections have different limits due to different characters, thus offering a variety of position accuracy. Therefore, this study evaluated the accuracy of real-time corrections, VRS, MAX, IMAX, D-GNSS, and Nearest Base, for the coordinates at two different times, morning and evening. The study was conducted at two different times to make it easier for users to choose a suitable and quality time to conduct observations. This research was implemented on the pillars at the calibration site of Politeknik Sultan Haji Ahmad Shah (POLISAS) in Kuantan, Pahang. The coordinates in the pillar become a benchmark to differentiate with real-time correction coordinates. The result of that difference can be used to analyse the level of accuracy for real-time corrections. The study’s findings show that the real-time correction accuracy of the VRS type is the most stable and has the highest accuracy. Nearest Base and MAX corrections also give relatively good accuracy and can be improved by increasing observation time and depending on the area. IMAX produces inconsistent results with relatively low accuracy, but some techniques can be applied to obtain good accuracy. D-GNSS type corrections give inconsistent results and low position accuracy as it utilises code measurement only. The research concludes that the best correction is VRS. The Nearest Base and MAX produce acceptable accuracy and can be safely chosen over IMAX and D-GNSS.
