DESENet: a bilateral network with detail-enhanced semantic encoder for real-time semantic segmentation
Authors: Tang Qingsong , Min Shitong , Shi Xiaomeng , Zhang Qi , Liu Yang 
Published: November 2024

Abstract
Real-time semantic segmentation is widely used in various domains such as autonomous driving and medical imaging. Most real-time semantic segmentation networks adopt an encoder–decoder structure. During encoding, feature maps undergo multiple downsampling stages to enhance computational efficiency and enlarge the receptive field. However, this process may lead to the loss of detailed information, which may not be fully recovered during upsampling. Moreover, upsampling semantic features may cause blurring and deviations due to the lack of spatial detail information. To mitigate these issues, we use spatially guided cross-resolution self-attention to improve the upsampling of the semantic features by supplementing detailed information from the spatial branch. Furthermore, we incorporate an inductive bias into the cross-resolution attention mechanism to enhance its ability to learn generalized features. Additionally, we design a semantic feature extraction block, and a spatial feature extraction branch to construct a lightweight backbone. The results on Cityscapes and CamVid show that the proposed model achieves a good balance between accuracy and parameter size. Specifically, it obtains 74.2% and 71.5% mIoU on the two test datasets with 1.31 M parameters, respectively. Code is available on https://github.com/clearwater753/DECENet.
An explicitly magnetic modified embedded atom method formalism for coupled spin dynamics and molecular dynamics
Authors: Dickel D , Baskes M I 
Published: November 2024

Abstract
In this paper, we augment the modified embedded atom method formalism to include magnetic spin–spin interactions for elements with a persistent magnetic moment. While previous spin coupling methods have been based on pair potentials, our Magnetic MEAM formalism, which we term MagMEAM, incorporates the many-body and angular effects of MEAM allowing for the strength of the magnetic interaction to vary with atomic environment. In particular, this allows potentials using this formalism to differentiate the magnetic interaction of different stable phases of magnetic elements such as the ferritic and austenitic phases of iron. This, in turn, allows for a more robust and realistic description of magnetism in polymorphic materials than was previously possible. The motivation for MagMEAM, including the insufficiency of magnetic pair potentials, is presented and the structure of the formalism is developed. A sample iron potential is developed using this formalism and shown to exceed the capabilities of existing magnetic pair potentials by simultaneously reproducing the magnetic energy of both martensite and austenite as well as the dynamic mechanical and magnetic properties of martensite. This newly designed formalism will allow for deeper explorations in the the complex interaction between different phases of polymorphic magnetic materials at the molecular dynamics scale.
Feedback switching control of a walking piezoelectric actuator for trajectory tracking
Authors: Ruan Zhiwei , Li Qin , Guo Liang , Ding Chenyang 
Published: November 2024

Abstract
This paper proposes a feedback switching control (FSC) scheme for a walking piezoelectric actuator (WPA) to track a time-varying trajectory. A WPA has two feet with each foot integrated with a clamp and shear piezoelectric stack actuators (PSAs). The first foot pushes the stage translator a step forward when clamped while the second foot is reset and retracted; subsequently, ‘foot switching’ occurs; as a result, the second foot is clamped to push the translator to make a next step forward and the first foot is reset and retracted. To make sure that the translator is always controlled in closed-loop no matter which foot is clamped, the FSC scheme is proposed. It consists of a clamping waveform generator which converts the trajectory into control signals for the clamp PSAs of the two feet and a feedback controller which provides control signals for the two shear PSAs of the feet. Experimental results show that the proposed control scheme achieves a tracking error of 0.028 µm for a constant velocity trajectory, which is a 75% reduction compared to the 0.113 µm of waveform-based control with iterative learning control compensation in literature.

Abstract
Recently, solving the complicated nonlinear partial differential equations has become very important demand in order to simulate their physical phenomena. This manuscript focuses on extracting the wave solutions of (3 + 1)-dimensional generalized B-type Kadomtsev-Petviashvili equation (GBKPE), which demonstrates the behavior of nonlinear waves in fluid mechanics. The improved modified extended Tanh function (IMETF) method is the suggested method to do this task as it gives different types of solutions. This method enables us to obtain many solutions, such as Jacobi elliptic, dark soliton, and singular soliton, exponential, and singular periodic wave solutions. Additionally, for more illustrations graphical visual representations of some solutions are provided.
Numerical investigation on the polarization-dependent light extraction of 275-nm AlGaN based nanowire with bowtie antenna array or passivation layer
Authors: Nie Kui-Ying , Fang Ming , Hu Zonghua , Ren Fang-Fang 
Published: November 2024

Abstract
The low light extraction efficiency (LEE) is one of the major factors hindering the application of AlGaN based deep ultraviolet (DUV) light-emitting diodes (LEDs). Here we investigate the LEE of AlGaN based nanowire (NW) DUV LEDs emitting at 275 nm for bare NW, NW integrated with aluminum (Al) bowtie antenna array, and NW with passivation layer under transverse-electric (TE) and transverse-magnetic (TM) polarization. It is observed that by integrating plasmonic Al bowtie antenna array with AlGaN based NW, the LEE up to 83% and 74% can be achieved under TE and TM polarization. In addition, the effect of the three different passivation layer SiO2, SiNx and AlN on the LEE of AlGaN based NW is also analysed, the results suggests that SiO2, which has smaller refractive index than NW core, could extract more photons from the NW and lead to large enhancement of LEE. For SiNx and AlN passivation layer, which has refractive index similar to the NW core, have strong coupling with the NW core, when the thickness of passivation layer satisfy resonance coupling conditions, the LEE could be achieved more than 80% for both TE and TM polarization. These integrated NW/antenna array and NW with passivation layer system can provide guidelines for designing other nano-photonic devices.
Styrene-Butadiene-Styrene polymer modified bitumen: A review on compatibility and physico-chemical properties
Authors: Bansal Shubham , Gupta Vivek , Chopra Tanuj , Mehta Rajeev 
Published: November 2024

Abstract
The triblock elastomeric copolymer Styrene-Butadiene-Styrene (SBS) improves the engineering properties of bitumen and the performance parameters of flexible pavements. Although research investigations have been conducted worldwide, the literature lacks a comprehensive review to provide the up-to-date research status in this field. The current review summarizes the research findings on the compatibility, stability, physical properties, microscopic characterization, and chemical characterization of SBS modified bitumen. Quantitative analysis of physical test results concerning major pavement distresses shows improvement, particularly in high-temperature zones. The interlocked state of phase transition can be achieved at SBS content between 5%–6% and the optimum SBS content has been reported to lie within this range. The blending temperature of SBS modified bitumen varies between 140 °C–210 °C out of which 180 °C is the most frequently used by researchers. In addition, physical and chemical characteristics of aged binder have been reviewed. Aging indices (residual penetration ratio, change in softening point, viscosity aging ratio, residual ductility ratio) didn’t show any consistent trend, which establishes the need of exploring the co-additives to substantially improve the aging deterioration. Preliminary research on nano-additives showed the improved storage stability at high temperature and the performance of aged modified bitumen. This review has drawn essential conclusions and highlights existing research gaps for peer researchers and field engineers.

Abstract
In this study, 304 stainless steel (SS304) substrates were used for the first time for the deposition of cubic silver antimony sulfide selenide (AgSb(S, Se)2) films. The AgSbS2 films were deposited using chemical bath deposition (CBD) followed by a one-step selenization process. Amorphous AgSbS2 films were produced through two sequential chemical depositions carried out over 4 h at 2 °C. The transformation from the amorphous state to cubic AgSb(S, Se)2 was achieved via selenization under ambient air conditions. Grazing incidence x-ray diffraction (GIXRD) confirmed the formation of cubic AgSbS1.7Se0.3 and AgSbS1.5Se0.5 solid solutions, with a calculated crystal size of approximately 9 nm. Raman spectroscopy revealed the amorphous nature of the as-deposited AgSbS2 films, with an asymmetric band observed at 331 cm−1, while polycrystalline AgSb(S, Se)2 films exhibited vibrational modes at 147, 190, 205, 253, 270, 324, and 493 cm−1. Scanning electron microscopy (SEM) analysis indicated a transformation of the granular morphology of AgSbS2 films into a smoother surface upon selenization. Energy dispersive spectroscopy (EDS) detected selenium incorporation up to 11.4 atomic percent (at%) in the AgSbS1.5Se0.5 film. The optical band gap (E

g
) was modulated from 1.71 eV to 1.47 eV, depending on the selenium content introduced through selenization. The C/SS304/AgSb(S, Se)2/C structure fabricated on stainless steel substrates exhibited ohmic contact, suggesting its potential for application in flexible solar cells.
Initial-offset and amplitude control of multi-scroll attractor in a chaotic jerk system
Authors: Jin Zihan , Wang Ning , Zhang Guoshan 
Published: November 2024

Abstract
With the gradual deepening of research on chaos, in order to flexibly apply chaos, offset boosting and amplitude control have become a hot topic. However, few people have studied chaotic systems with multi-scroll attractor under initial conditions. This paper constructs and analyzes a simple four-dimensional chaotic system. Unlike other extension methods that modify the original seed system, this method does not make any changes to the original seed system, only adds a new variable in the extension dimension. It is found that the proposed system can achieve offset boosting and amplitude control by changing the initial values, and the system has characteristics such as multi-scroll attractors, infinite equilibrium points, symmetry, and so on. Finally, FPGA hardware implementation was carried out to verify the numerical results.
Normalization of hot deformation parameters for activation energy analysis in metallic alloys
Authors: Ahmedabadi Parag M 
Published: November 2024

Abstract
Depending on the melting point of a given alloy, the temperature range for hot deformation of alloys varies widely. Consequently, the apparent activation energy of hot deformation, Q, is greatly influenced by the temperature range as well as the strain rate applied during hot deformation. The purpose of this investigation is to normalize hot deformation parameters—temperature and strain rate—to study their effects on activation energy. Seventy published hot-deformation datasets were used to investigate the effects of normalized hot-deformation variables on Arrhenius-type constitutive model parameters. Flow stress, strain rate, and temperature from sample datasets were normalized to the range [0, 1] and fitted with an Arrhenius-type model. The results showed that, for normalized parameters, the activation energy has exponential relationships with the partial derivative of flow stress with respect to strain rate and temperature.
Broadband polarization-insensitive terahertz absorber based on Ta2O5 snowflake-like structure
Authors: Ji Shijun , Qin Mingfei , Dai Handa , Li Jingjin 
Published: November 2024

Abstract
In this paper, an ultra-broadband tantalum pentoxide (Ta2O5) all-dielectric metamaterial absorber is proposed from the far-infrared to the terahertz range, which exhibits polarization-insensitive and wide-angle characteristics. The absorber consistently demonstrates an impressive absorption rate exceeding 90% within the frequency range from 1.1 THz to 20 THz. Such an absorber can have a bandwidth and relative bandwidth ratio of 18.9 THz and 179.15%. We employ an equivalent circuit model to simulate the performance of the absorber using transmission line theory, which facilitates near-perfect absorption by finely tuning the geometrical parameters of the structure to match the input impedance with that of free space. Detailed calculations and analyses of the electric and magnetic field distributions, as well as power loss density, are presented to clarifying the underlying mechanisms of absorption. The design of the proposed absorber inherently provides insensitivity to polarization angles and sustains superior absorption efficiency at substantial incidence angles. An exhaustive exploration of the influence of structural variations on the performance of the absorber has been conducted. Looking ahead, the proposed absorber can be potential application in enhanced terahertz imaging, terahertz communication systems, novel energy harvesting solutions and broad scientific research endeavours.
High-fidelity analysis of the electro-optical non-equivalence of planar electrical substitution radiometers*
Authors: Gieseler J , White M G , Harber D , Haun R , Tomlin N A , Lehman J H 
Published: November 2024

Abstract
We present the results of a finite element analysis of the electro-optical non-equivalence of planar electrical substitution radiometers with vertically aligned carbon nanotube absorbers, operating at either room or cryogenic temperature. These detectors are the basis of the new room temperature standards of the Laboratory for Atmospheric and Space Physics’ (LASP) Total solar irradiance Radiometer Facility and the Spectral solar irradiance Radiometer Facility, and the NIST Boulder open beam cryogenic radiometer facility. We show that the detector of our cryogenic electrical substitution radiometer has no significant electro-optical non-equivalence. Further, we also show that with careful detector design, the non-equivalence can be minimized at room temperature. It was found that in general the non-equivalence cannot be deduced from the temperature mismatch between the electrical and the optical states without considering the conductance mismatch and optical power input. The results are regarded as being precise rather than absolute to account for potentially unknown modeling errors. The numerical accuracy is typically less than 5 ppm.

Abstract
The ‘density limit’ is one of the fundamental bounds on tokamak operating space, and is commonly estimated via the empirical Greenwald scaling. This limit has garnered renewed interest in recent years as it has become clear that ITER and many tokamak pilot plant concepts must operate near or above the Greenwald limit to achieve their objectives. Evidence has also grown that the Greenwald scaling—in its remarkable simplicity—may not capture the full complexity of the density limit. In this study, we assemble a multi-machine database to quantify the effectiveness of the Greenwald limit as a predictor of the L-mode density limit and compare it with data-driven approaches. We find that a boundary in the plasma edge involving dimensionless collisionality and pressure,

, achieves significantly higher accuracy (false positive rate (FPR) of 2.3% at a true positive rate (TPR) of 95%) of predicting density limit disruptions than the Greenwald limit (FPR of 13.4% at a TPR of 95%) across a multi-machine dataset including metal- and carbon-wall tokamaks (AUG, C-Mod, DIII-D, and TCV). This two-parameter boundary succeeds at predicting L-mode density limits by robustly identifying the radiative state preceding the terminal MHD instability. This boundary can be applied for density limit avoidance in current devices and in ITER, where it can be measured and responded to in real time.

Abstract
EuF3: Gd @ tryptophan was synthesized via aqueous solution route at room temperature. The XRD studies shows hexagonal phase of synthesized nanoparticles with lattice parameters a = b = 6.966 (A°), c = 7.322 (A°). The lattice parameter values are in good agreement with (JCPDS card no 32-0373). The particle size of nanoparticles was calculated using Debye-Scherer formula and it is found to be 73.54 nm. Nanoparticles has flake like morphology having size of the order of 56 nm – 71 nm with nanoparticles has average size of 13 nm. The TEM image shows globular aggregates with assorted size were also seen with diameter 56 nm – 71 nm from which the flower like star structures originates. The TGA/DTA analyses of synthesized sample were studied up to 1500°C at heating rate of 0.01°C – 100°C/min. The variation in dielectric constant ε′, dielectric loss ε″ and tangent loss (tan δ) with frequency (100 Hz – 5 MHz) was studied at room temperature. The dielectric constant and dielectric loss are found to decrease exponentially with frequency. The low value of dielectric loss at higher frequencies indicates its use in electronic industry.

Published: November 2024

Abstract
There is a growing global interest in natural tourism, which presents new opportunities for the development of small island regions. Several studies have shown that the development of tourism in the Indonesian Archipelago has led to several significant issues, so within the eastern islands of Sumenep— including Gili genting. The richness of natural features and the unique Maduranese Archipelago community, shown by Kahuripan area. However, the potential for developing a nature-based tourism sector (geosite) with the richness of geotourism, has not been adequately considered yet. Therefore, this study aimed to: 1) conducting inventory of the educational geotourism potential; 2) carrying out evaluations using GAM; 3) developing recommendations for future development of Gili Genting Potential Asset as Archipelagic Geotourism Development. According to inventory analysis, the Kahuripan Geosite consists of six Stop site with various information. The MV assessed 4.25 and AV counted of 4.75. The GAM diagram results indicate that the Kahuripan Geosite lies on Q22 tend to be moderate class of MV and AV. This quadrant suggests that the physical aspects of the geosites are quite interesting, while the tourism management that has begun to be developed needs to be further elaborated towards the geotourism-based education concept.

Abstract
This investigation delves into the temporal and spatial dynamics of turbidity in the Derawan Islands, Indonesia, utilizing a comprehensive approach that combines multispectral satellite imagery from Sentinel-2, in-situ measurements via AAQ Licor sensors across 165 observation stations, and continuous data collection from a Turbidity Logger. Situated within the Coral Triangle, understanding the turbidity variations in the Derawan Islands is crucial for the conservation and sustainable management of its marine ecosystems. Our research developed and validated empirically derived algorithms to accurately estimate turbidity, utilizing a strategic partition of in-situ data—70% for model development and 30% for validation. This approach resulted in robust models, demonstrating their efficacy with Root Mean Square Error (RMSE) values as low as 0.85 and R-Squared (R2) values up to 0.56, indicating a high degree of accuracy in satellite-derived turbidity measurements. The study unveiled significant spatial and temporal turbidity heterogeneity, linking these variations to both natural and anthropogenic factors. The high-resolution data from the Turbidity Logger revealed critical diurnal fluctuations and short-term turbidity events, providing insights into the dynamic marine environment of the Derawan Islands.
