Published: April 2024

AbstractFifteen helminth species were collected from 47 wolves (Canis lupus ) which were surveyed from 1993 to 1999 in northwestern Spain. These included the trematode Alaria alata (2.1%); the cestodes Taenia hydatigena (44.7%), T. multiceps (29.8%), T. serialis (2.1%), Dipylidium caninum (6.4%) and Mesocestoides sp. aff. litteratus (4.2%); and the nematodes Pearsonema plica (7.4%), Trichuris vulpis (10.6%), Trichinella britovi (12.8%), Ancylostoma caninum (8.5%), Uncinaria stenocephala (51.1%), Toxocara canis (6.4%) Toxascaris leonina (4.2%), Angiostrongylus vasorum (2.1%) and Dirofilaria immitis (2.1%). Only two wolves were not infected. A single infection occurred in 28.9% of the cases, but the commonest infracommunity (31.1%) involved three species. The helminths Alaria alata, Taenia hydatigena, Mesocestoides sp. aff. litteratus, P. plica, Trichuris vulpis, and Ancylostoma caninum parasitizing C. lupus are reported for the first time in Spain. Taenia serialis and D. immitis are reported for the first time in wolves in Europe. Angiostrongylus vasorum represents a new host record for wolves. The helminth fauna of Spanish wolves is compared with that of other European wolf populations. Some epidemiological considerations of the helminth fauna of wolves in Spain and the health risk to humans are also discussed.

Published: April 2024

AbstractHistopathology of the lung and total IgE in serum were compared in toxocariasis and allergic asthma murine models using BALB/c and C57BL/6 mice. Infection with Toxocara canis resulted in both strains of mice in marked histological changes and increased levels of total serum IgE. The ovalbumin (OVA) sensitization/challenge treatment for the induction of allergic asthma resulted in similar histological changes in BALB/c and, to a less extent, in C57BL/6 mice. Serum IgE levels of OVA-treated C57BL/6 mice were low. Histological changes observed included perivascular infiltration with eosinophils and mononuclear cells, peribronchiolitis, alveolitis and mucus production. Although these changes in addition to increased IgE production did occur in T. canis-infected C57BL/6 mice they were more pronounced in BALB/c mice. Thus, BALB/c mice appear to be the most appropriate strain of mice to perform studies on the possible connection between infection with T. canis and allergic asthma.

Published: April 2024

AbstractOcular toxocariasis is a clearly defined disease. However, much remains to be learned concerning the migratory route, ocular changes, diagnosis and treatment. Studies in paratenic hosts have contributed to our understanding and will yield more information. Various experimental animals have been used, such as mice, rabbits, guinea pigs, primates, hamsters and gerbils. Of these, the last appear to be the most appropriate model due to their high susceptibility to ocular infection. Results obtained from different animal models are often not comparable due to the fact that dose and routes of inoculation are diverse. Early stages in the pathogenesis of ocular toxocariasis are manifested by haemorrhages in the anterior chamber and iris, replaced in time by accumulations of white cells. Ocular migration produces an early cell reaction, formed by an infiltration of neutrophils accompanied by vasculitis and retinal microinfarcts. Over a period of time, an increase of macrophages and the distribution of the infiltrates is observed. Later, granulomatous lesions are formed. These do not necessarily contain a larva and their appearance varies in different animal models. Local production of IgE and the presence of specific IgG have been described.

Abstract
Blistering is a phenomenon sometimes observed in sputtered-deposited thin films but seldom investigated in detail. Here, we consider the case of titania-doped germania (TGO)/silica multilayers deposited by ion beam sputtering. TGO is a candidate as high refractive index material in the Bragg mirrors for the next iteration of gravitational waves detectors. It needs to be annealed at 600 ∘C for 100 h in order to reach the desired relaxation state. However under some growth conditions, in 52-layer TGO/silica stacks, blistering occurs upon annealing at a temperature near 500 ∘C, which corresponds to the temperature where Ar desorbs from TGO. In order to better understand the blistering phenomenon, we measure the Ar transport in single layers of TGO and silica. In the case of

<

1 µm-thick TGO layers, the Ar desorption is mainly limited by detrapping. The transport model also correctly predicts the evolution of the total amount of Ar in a 8.5 µm stack of TGO and silica layers annealed at 450 ∘C, but in that case, the process is mainly limited by diffusion. Since Ar diffusion is an order of magnitude slower in TGO compared to silica, we observe a correspondingly strong accumulation of Ar in TGO. The Ar transport model is used to explain some regimes of the blisters growth, and we find indications that Ar accumulation is a driver for their growth in general, but the blisters nucleation remains a complex phenomenon influenced by several other factors including stress, substrate roughness, and impurities.
A hybrid deep learning model for fault diagnosis of rolling bearings using raw vibration signals
Authors: Jiang Liang , Tang Jiahui , Sun Ning , Wang Songlei 
Published: April 2024

Abstract
The fault symptoms of rolling bearings are subject to various interferences in complex industrial environments, so achieving accurate, robust, and generalized fault diagnosis has become a key research direction. This article proposes a rolling bearing fault diagnosis method based on 1D-Inception-SE, which combines the 1D-Inception network model with Squeeze and Excitation Attention and can directly use the original vibration signals for fault diagnosis. The method incorporates the Adaptive Batch Normalization algorithm to enhance the model’s generalization performance in the presence of noise interference and cross-load diagnostics. Performance tests on Paderborn University Bearing and Case Western Reserve University datasets show that our approach achieves superior recognition accuracy compared to other models under similar and varied loads, as well as different signal to noise ratio. Ablation and visualization tests confirm the rationality and effectiveness of the model structure.

Abstract
We have experimentally demonstrated spatially selective absorption in Ag-SiO2-Ag based trilayer thin films by tuning the deposition angle of SiO2 layer. These structures generate cavity resonance which can be tuned across the substrate locations due to spatially selective thickness and refractive index of silicon oxide (SiO2) film sandwiched between metallic silver (Ag) mirrors. Spatially selective property of SiO2 film is obtained by oblique angle deposition technique using an electron beam evaporation system. The resonance wavelength of absorption in this trilayer structure shifts across the substrate locations along the direction of oblique deposition. The extent of shift in resonance increases with increase in angle of deposition of SiO2 layer. 4.14 nm mm−1 average shift of resonance wavelength is observed when SiO2 is deposited at 40° whereas 4.76 nm mm−1 average shift is observed when SiO2 is deposited at 60°. We observed that the width of resonance increases with angle of deposition of the cavity layer and ultimately the resonant absorption disappears and becomes broadband when SiO2 is deposited at glancing angle deposition (GLAD) configuration. Our study reveals that there is a suitable range of oblique angle of deposition from 40° to 60° for higher spatial tunability and resonant absorption whereas the absorption becomes broadband for glancing angle deposition.

Abstract
We report on the fabrication of a novel design of GaAs/(In,Ga)As/GaAs radial nanowire heterostructures on a Si 111 substrate, where, for the first time, the growth of inhomogeneous shells on a lattice mismatched core results in straight nanowires instead of bent. Nanowire bending caused by axial tensile strain induced by the (In,Ga)As shell on the GaAs core is reversed by axial compressive strain caused by the GaAs outer shell on the (In,Ga)As shell. Progressive nanowire bending and reverse bending in addition to the axial strain evolution during the two processes are accessed by in situ by x-ray diffraction. The diameter of the core, thicknesses of the shells, as well as the indium concentration and distribution within the (In,Ga)As quantum well are revealed by 2D energy dispersive x-ray spectroscopy using a transmission electron microscope. Shell(s) growth on one side of the core without substrate rotation results in planar-like radial heterostructures in the form of free standing straight nanowires.
Soliton solutions and the interaction behaviour of the (3+1)-dimensional Jimbo-Miwa-like equation
Authors: Ma Hongcai , Qi Xinru , Deng Aiping 
Published: April 2024

Abstract
In this article, we aim to study the dynamical behavior of the (3+1)-dimensional Jimbo-Miwa-like (JML) equation. By using different methods, different forms of solutions are obtained. At the same time, in the same method, we also study the influence of parameters on the solution by changing the values of parameters. Firstly, we use the bilinear method to obtain the Y-type and X-type soliton solutions. Secondly, using different test functions, we obtain the interaction phenomenon between the solutions, which is obtained by a lump solution and a kink wave solution or by a lump solution and multi-kink wave solutions. Lastly, on the basis of the study of the single lump solution, we have made a further exploration. We not only obtain the lump-periodic solution, which verifies the periodicity, but also obtain the lump-soliton solution. For the above wave solutions, we graphically describe their dynamical properties with MAPLE. It is worth mentioning that the content of our study is different from the existing research: we not only use different methods to study the solutions of the JML equation, but also use different parameter relations and different values of parameters to study the changes of solutions. At the same time, we also use different test functions to study the same form of wave solutions. It is intuitive to see the influence of the test function on the dynamic behavior of the solution. In addition, our results not only enable us to understand the dynamic properties of such equations more intuitively, but also provide some ideas for researchers to facilitate more indepth exploration.

Published: April 2024

Abstract
Herein, we report the phase transformation mechanism of the nominal Si(001) surface driven by hydrogen thermal annealing. The surface energies of H-terminated Si(001) surface with different phase structures were calculated by density functional theory. The results show that the surface phase with monoatomic steps can transform into the surface phase with diatomic steps under proper ranges of hydrogen chemical potential. Combining thermodynamic and kinetic factors, the phase transformation can’t occur when annealing temperature lower or higher than 800 °C. In addition, surface phases with different types of diatomic steps are alternately transformed through the intermediate phase with monoatomic steps and the imperfection of the transformation process gradually increases with the extension of annealing time. Finally, different experiments have been carried and the experimental results are in good agreement with the phase transformation mechanism. This study provides complete theoretical mechanism and process parameters for controlling the phase structures of the nominal Si(001) surface through hydrogen thermal annealing.

Published: April 2024

Abstract
NOT gate is one of the basic units in quantum computing. While it suffers from the noise during the complex operation. In this paper, we simulate the NOT gate on the superconducting phase qubit and solve the noise problem by maximizing the impact of noise cancellation. We first extract the noise term from the Hamiltonian and reset it to zero. Then we give two kinds of pulses based on the non-noise term for the quantum gate. By using these pulses, the fidelity would be improved and benefit quantum computing.
Nonlinear Seebeck and Peltier effects in a Majorana nanowire coupled to leads

Published: April 2024

Abstract
We theoretically study nonlinear thermoelectric transport through a topological superconductor nanowire hosting Majorana bound states (MBSs) at its two ends, a system named as Majorana nanowire (MNW). We consider that the MNW is coupled to the left and right normal metallic leads subjected to either bias voltage or temperature gradient. We focus our attention on the sign change of nonlinear Seebeck and Peltier coefficients induced by mechanisms related to the MBSs, by which the possible existence of MBSs might be proved. Our results show that for a fixed temperature difference between the two leads, the sign of the nonlinear Seebeck coefficient (thermopower) can be reversed by changing the overlap amplitude between the MBSs or the system equilibrium temperature, which are similar to the cases in linear response regime. By optimizing the MBS–MBS interaction amplitude and system equilibrium temperature, we find that the temperature difference may also induce sign change of the nonlinear thermopower. For zero temperature difference and finite bias voltage, both the sign and magnitude of nonlinear Peltier coefficient can be adjusted by changing the bias voltage or overlap amplitude between the MBSs. In the presence of both bias voltage and temperature difference, we show that the electrical current at zero Fermi level and the states induced by overlap between the MBSs keep unchanged, regardless of the amplitude of temperature difference. We also find that the direction of the heat current driven by bias voltage may be changed by weak temperature difference.
Porous structures inspired by porcupine quill: multiscale design optimization approach
Authors: Lan Tian , Fox Kate , Tran Phuong 
Published: April 2024

Abstract
This paper presents a novel approach for designing a freeform bending-resistant structure from the combination of explicit discrete component-based topology optimization (TO) and the porcupine quill-inspired features. To embed the porcupine quill’s features into the TO formulations, the method involves constructing discrete components at various scales to imitate features including solid shell, stochastically distributed pores, and graded stiffeners. The components are iteratively updated, and the optimization process allows for the grading of quill-inspired features while achieving optimal structural compliance under bending loads. The proposed approach is demonstrated to be effective through the resolution of Messershmitt–Bolkow–Blohm (MBB) beam designs, parameterized studies of geometric parameters, and numerical validation of long-span and short-span quill-inspired beam designs. By examining the von Mises stress distribution, the study highlights the mitigation of material yielding at the shell region brought by the geometric features of porcupine quills, leading to the potential theory support for the bending resistance. The optimized MBB beams are manufactured using the material extrusion technique, and three-point bending tests are conducted to explore the failure mitigation capability of the quill-inspired beam under large deformation. Consequently, the study concludes that the proposed quill-inspired component-based TO approach can design a structure with excellent bending resistance according to the improved energy absorption as well as increased deformation after reaching 75% peak load.
The influence of borehole lengths on a numerical model of a double-tube vertical ground heat exchanger

Published: April 2024

Abstract
GHEs are underground pipes that transmit heat between the earth and pipes. ANSYS Fluent was used to numerically investigate the thermal and hydraulic performance of a vertical twin tube ground-linked heat exchanger in a pile foundation in cooling mode. The CFD analysis uses three borehole length models—M1-10 m, M2-15 m, and M3-20 m—with flow rates from 1-100 lit/min and Reynolds numbers from 162 to 1625. The numerical results show that the average heat transfer rate of the Model M1 was 13% higher than that of the Model M2, 32% higher than that of the Model M3, and 95% higher than that of the Model M2. The pressure drop was minimal for 1 to 5 lit/min (laminar flow condition) but very high for 10 to 100 lit/min. The bore cavity length increased the pressure drop and decreased the average output temperature. These two-tube vertical GHEs with optimized length and selection of pipe materials can improve natural convection heat transfer by contacting ground waters.

Published: April 2024

Abstract
Understanding the interaction between drug-metal complexes is important to find out the pharmacological characteristics of a drug. In this work, one of the μ-opioid analgesic type of drug, tapentadol has been used to study the interaction of tapentadol with several metal ions such as Ca (II), K (I) Cr (III), Cu (II), Fe (III), Co (II), and Ni (II) using UV-Vis and FTIR spectroscopy. It was found that tapentadol forms drug-metal complexes with transition metals like Fe (III) and Ni (II) only in acidic conditions. Whereas Cu (II) can interact with tapentadol both in acidic and basic conditions. This study may help to understand the interactions of μ-opioid drugs with the metal ions which ultimately help to develop new drugs of this class with more efficacy.

Published: April 2024

Abstract
This investigation aims to evaluate the influence of heat treatment on the hardness and microscopic characteristics of a specific grade of medium carbon steel, namely, the American standard D6A Ultra High-Strength Steel, which contains 0.47% carbon in its composition. After preparation, specimens were heated in a muffle furnace at a temperature of 830°C and held for 90 minutes, followed by quenching. Subsequently, the specimens underwent tempering at a temperature of 600°C for 60 minutes. The hardness and microscopic evaluation of the heat-treated steel were determined. The results also indicate a rapid increase in hardness with a decrease in thickness for the heat-treated material. For HRA (Rockwell Hardness A Scale) times of 5s and 10s, the hardness enhancement percentages were 29% and 103%, respectively, compared to specimens without heat treatment. Furthermore, a chamber pressure test assessed the suitability and optimal design of Ultra High-Strength Steel for a pressure vessel in a mortar gun. As the outer radius increases, there is a corresponding decrease in axial stress, hoop stress, and the maximum limit of ultimate stress for both internal pressures within the pressure vessel. For internal pressures of 100 MPa and 85 MPa, the optimal inner radius for the pressure vessel is determined to be 0.053m and 0.051m, respectively.

Published: April 2024

Abstract
In underdeveloped nations where fuel and electricity are expensive, crop drying using solar power is a practical and affordable method of food preservation. For farmers in rural areas, it can be difficult or impossible to preserve fruits for later use without access to fuel and huge drying systems. Drying of potatoes in the sun is carried out with industrial dryers integrating solar power. This experiment shows how to design and optimize drying systems for usage in developing nations. A model of an industrial sun-drying system has been created and validated through experimental testing. The ambient temperature is between 28°C and 33°C, while the drying chamber’s temperature ranges from 30°C to 48°C at a flow rate of 1.8 m/s. The moisture content of the dried potato sample was 84.7% and 8.27% under loaded conditions and using only silica gel respectively. We use a photovoltaic (PV) solar panel-powered heating element coil in combination with solar energy that improves the efficiency of agricultural dryers.

Published: April 2024

Abstract
The direct liquid cooling (DLC) of the data center is becoming popular due to its higher heat removal from the computer chips. The direct liquid cooling method is more effective than the conventional air-cooling system and reduces the higher infrastructure and maintenance costs. The DLC reduces the chip failure rate drastically and increases the life of the data centers. Different liquids can be used as a coolant and some manufacturers are coming up with different coolants where the liquid has high thermal efficiency and is electrically non-conductive. In this article, a heat-transfer cold plate made of aluminum is designed and a different combination of heat-transfer liquids (Distilled water, Ethylene Glycol, and Polyethylene Glycol) is tested to find a comparatively better combination of heat-transfer liquid. It was observed that the combination of Ethylene Glycol and distilled water performs better than other combinations. It was also found that the coolant flow rate plays an important role in the cooling of the chips as well.
