Published: September 2024

AbstractInflammatory bowel diseases (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), are chronic inflammatory conditions affecting the digestive tract. This study examines 188 IBD patients in a private healthcare service in Canoas/RS, Brazil, aiming to understand their clinical profiles.Most patients were young adults, primarily white, with more women affected. Both CD and UC patients commonly experienced diarrhea, but blood in stools was more prevalent in UC. CD mostly affected the small intestine, while UC involved the rectum or extended through the colon. The diagnosis was prompt, with most CD cases diagnosed within six months and UC cases within twelve months of symptom onset. Family histories of IBD and colorectal cancer were observed, particularly in CD patients. Extraintestinal manifestations were more frequent in CD. Elevated CRP levels were common in CD, while FC values were elevated in both groups. Treatment approaches differed, with 5-ASA primarily used in UC and immunomodulators in CD. Biological therapy was less commonly employed initially.This study aligns with global IBD trends in demographics, symptoms, and disease locations. Early diagnosis likely results from specialized private healthcare, emphasizing the importance of timely diagnosis and tailored treatment.

Published: September 2024

Functional photoacoustic microscopy (PAM) requires laser sources with multiple wavelengths targeting abundant substances, where lipid and water are important components of living organisms. Here, we propose to use a single compact dual-wavelength passively Q-switched solid-state laser as the excitation source to directly achieve PA differentiation of water and lipid simultaneously. The main contribution of our work is to use the excitation difference under 1064- and 1176-nm lasers for mapping water and lipid in PAM, respectively. Meanwhile, the miniature structure (cavity size: ∼10 × 10 × 5.5 mm3) of the laser source is not only promising for portable applications but also benefits the PA-desired nanosecond (&lt;2 ns) laser pulse establishment. Our technique is confirmed by efficient PA imaging of water and lipid in biological tissues at high spatial resolution and improved sensitivity. This laser provides a novel and low-cost imaging source for PAM to track changes in water and lipid distribution.

Published: September 2024

Here we present measurements of dissociative and non-dissociative cross-sections for the electron impact of the CF4 molecule. The present experiments are based on a Recoil Ion Momentum Spectrometer (RIMS), a standard gas mixing setup for CF4, and a reference gas. The measurements were carried out at several electron energies up to 1 keV, covering the energy range of previous experiments. We apply the relative flow technique (RFT) to convert the relative cross-sections measured by the RIMS into absolute values. Using the combination of RIMS and RFT, ion collection and calibration errors were minimized. The results were compared with theoretical and experimental studies available in the literature. Previous electron impact experiments present relative cross-sections or use correction terms for the absolute cross-sections due to losses of energetic ions. We elucidate the differences between the new measurement method and the existing ones in the literature and explain why the present method can be considered reliable. Furthermore, we show how reducing correction terms affects the results.

Published: September 2024

Abstract
Strong empirical and phenomenological indications exist for large sea-quark admixtures in the low-lying excited baryons. Investigating the low-lying excited baryon Σ
*(1/2−) is important for determining the nature of the low-lying excited baryons. We review the experimental and theoretical progress on the studies of the Σ
*(1/2−). Although several candidates have received intensive discussions, such as Σ(1620) and Σ(1480), their existence needs further confirmation. Following the prediction of the unquenched quark models for the Σ
*(1/2−), many theoretical works suggested the existence of these states in various processes. Future experimental measurements could shed light on the existence of the low-lying excited Σ
*(1/2−) state.

Published: September 2024

Abstract
Acoustic signals are commonly used to analyze the vibration characteristics of ultrasonic transducers in many fields such as ultrasonic-assisted machining. In traditional measurements, the microphone is fixed at one or several points to measure the acoustic signal. However, the vibration characteristics of the ultrasonic transducer cannot be efficiently analyzed according to acoustic signals from one or several points without knowing the distribution of the sound pressure field. To comprehensively and efficiently analyze the acoustic signals radiated from the ultrasonic transducer, an ultrasonic pressure field measurement system for ultrasonic transducers in ultrasonic-assisted machining based on a 6-axis industrial robot is presented. A free-field condenser microphone is fixed to an industrial robot and can be positioned by the industrial robot to measure points in any attitude. Compared to traditional measurement methods, measurements based on industrial robots can improve the measurement range and flexibility. In addition, a robot measurement path generation algorithm based on the ant colony algorithm is proposed. The algorithm can generate and optimize measurement paths based on the shape of the tool to reduce measurement time and improve measurement accuracy. In addition to ultrasonic-assisted machining, this system can also be used in many applications that require ultrasonic transducers, such as acoustic field measurements for ultrasonic cleaners. Finally, we demonstrate the effectiveness and adaptability of the proposed method with two examples.
A novel plaintext-related dynamic DNA image encryption algorithm based on a 4D conservative chaotic system
Authors: Yan Shaohui , Zhang Jiandong , Jiang Defeng , Cui Yu 
Published: September 2024

Abstract
Conservative chaotic systems can circumvent the flaws of dissipative systems, as they do not form chaotic attractors, thus enhancing their resilience to attacks. In this paper, a new non-Hamiltonian 4D conservative system is proposed, and the system’s conservativeness and chaotic properties are confirmed through the analysis of equilibrium points, chaotic flow projections, Poincaré sections, Lyapunov exponents, and Hamiltonian energy. Moreover, the system exhibits rich dynamical behaviors such as multistability, spectral entropy complexity, and offset-boosting. Building on this, a plaintext-related initial state generation algorithm using hash function is proposed, increasing sensitivity to plaintext. Also, a dynamic DNA algorithm is proposed by using plaintext information to control DNA operations. This ensures that the encryption operation is unique for each image. This algorithm enriches the encoding rules, thus enhancing the algorithm’s security. Experimental results show that the algorithm exhibits outstanding performance and strong resilience against various attacks.
Single photon scattering with the giant and small atom interplay in a one-dimensional coupled resonator waveguide

Published: September 2024

Abstract
We study single photon scattering in a one-dimensional coupled resonator waveguide, which is dressed by a small and a giant artificial atom simultaneously. Here, we have set the small atom to be a neighbor to one leg of the giant atom, and the giant atom couples to the waveguide via two distant sites. When the small and giant atoms are both resonant with the bare resonator in the waveguide, we observe the perfect reflection of the resonant incident photon. On the other hand, when the small atom is detuned from the giant atom, the single photon reflection is characterized by a wide window and Fano line shape. We hope our work will pave the way for the potential application of small and giant atom hybrid systems in the study of photonic control in the low-dimensional waveguide structure.

Abstract

Objective. Training plays a significant role in motor imagery (MI), particularly in applications such as Motor Imagery-based Brain–Computer Interface (MIBCI) systems and rehabilitation systems. Previous studies have investigated the intricate relationship between cues and MI signals. However, the medium of presentation still remains an emerging area to be explored, as possible factors to enhance Motor Imagery signals. Approach. We hypothesize that the medium used for cue presentation can significantly influence both performance and training outcomes in MI tasks. To test this hypothesis, we designed and executed an experiment implementing no-feedback MI. Our investigation focused on three distinct cue presentation mediums—audio, screen, and virtual reality(VR) headsets—all of which have potential implications for BCI use in the Activities of Daily Lives. Main results. The results of our study uncovered notable variations in MI signals depending on the medium of cue presentation, where the analysis is based on 3 EEG channels. To substantiate our findings, we employed a comprehensive approach, utilizing various evaluation metrics including Event-Related Synchronization(ERS)/Desynchronization(ERD), Feature Extraction (using Recursive Feature Elimination (RFE)), Machine Learning methodologies (using Ensemble Learning), and participant Questionnaires. All the approaches signify that Motor Imagery signals are enhanced when presented in VR, followed by audio, and lastly screen. Applying a Machine Learning approach across all subjects, the mean cross-validation accuracy (Mean ± Std. Error) was 69.24 ± 3.12, 68.69 ± 3.3 and 66.1 ± 2.59 when for the VR, audio-based, and screen-based instructions respectively. Significance. This multi-faceted exploration provides evidence to inform MI-based BCI design and advocates the incorporation of different mediums into the design of MIBCI systems, experimental setups, and user studies. The influence of the medium used for cue presentation may be applied to develop more effective and inclusive MI applications in the realm of human–computer interaction and rehabilitation.
Binocularly incongruent, multifrequency-coded SSVEP in VR: feasibility and characteristics
Authors: Yang Liuyin , Sun Qiang , Van Hulle Marc M 
Published: September 2024

Abstract

Objective. Steady-state visual evoked potentials (SSVEPs) in response to flickering stimuli are popular in brain–computer interfacing but their implementation in virtual reality (VR) offers new opportunities also for clinical applications. While traditional SSVEP target selection relies on single-frequency stimulation of both eyes simultaneously, further called congruent stimulation, recent studies attempted to improve the information transfer rate by using dual-frequency-coded SSVEP where each eye is presented with a stimulus flickering at a different frequency, further called incongruent stimulation. However, few studies have investigated incongruent multifrequency-coded SSVEP (MultiIncong-SSVEP). Approach. This paper reports on a systematical investigation of incongruent dual-, triple-, and quadruple-frequency-coded SSVEP for use in VR, several of which are entirely novel, and compares their performance with that of congruent dual-frequency-coded SSVEP. Main results. We were able to confirm the presence of a summation effect when comparing monocular- and binocular single-frequency congruent stimulation, and a suppression effect when comparing monocular- and binocular dual-frequency incongruent stimulation, as both tap into the binocular vision capabilities which, when hampered, could signal amblyopia. Significance. In sum, our findings not only evidence the potential of VR-based binocularly incongruent SSVEP but also underscore the importance of paradigm choice and decoder design to optimize system performance and user comfort.

Published: September 2024

Abstract
In this article, the effect of adding Sodium Lauryl Sulphate (SLS), a surfactant to base fluid acetone on heat transfer enhancement during the pool boiling process on a Copper substrate is studied. The aqueous solution is prepared with different concentration of surfactant of SLS varying from 200 ppm to 1000 ppm. By adjusting the super heat degree, the heat flux to the copper working substrate can be changed. The heat transfer coefficient is determined taking different heat flux values and surfactant concentrations. It has been shown that adding surfactant, as opposed to pure liquid, improves the Pool Boiling Heat Transfer Coefficient (PBHTC) when the surfactant concentration is within critical micelle concentration (CMC). The maximum enhancement in heat transfer coefficient is noted as 650 % in 400 PPM aqueous solution of SLS - Acetone at heat flux of 13.636 kW/m2.The lowest surface super heat is found to be 0.9 °C at 19.09 kW/m2 in 400 ppm SLS concentration compared to 3.7 °C in pure acetone. Therefore, the reduction in excess temperature is found to be 75.675 %. When heat flux is 65.45 kW/m2 in 400 ppm solution, the heat transfer coefficient is determined to be 26.18 kW/m2 °C, which is 148% larger than the value of 10.557 kW/m2 °C in pure acetone.

Published: September 2024

Abstract
Efficient heat transfer is very crucial for the various industries in electrical, nuclear power, aerospace and automobile fields. By exhibiting improved thermal conductivity, nanofluids have emerged as an alternative for enhanced thermal and energy efficiency applications. The present study examines the movement of nano fluid across a surface that extend when heat radiation and magnetic fields are present. Using appropriate similarity variables, governing partial differential equations are converted to nonlinear ordinary differential equations. Engineering factors which are discussed include Nusselt number and skin friction coefficient. Numerical analysis is optimized using the response surface methodology. The Response Surface Methodology (RSM) with face-centred Central Composite Design is utilized to calculate heat flux transfer at the stretched sheet. The interaction of heat radiation, magnetic field parameter, and solid volume fraction are investigated in the present work. It is worth noting that the local Nusselt number responds positively to the magnetic field parameter and the solid volume fraction, whereas the skin friction coefficient responds negatively.

Published: September 2024

Abstract
Solar energy is considered free and clean energy. Solar drying technology is adopted as a sustainable way of food preservation. In this research, the drying of mango and preparation of bread toast has been investigated through experiments. A baffled-type solar dryer with a feature for hot air exhaust recirculation has been used for the experimental analysis. The collector efficiency, drying efficiency, and drying rate have been calculated by creating turbulence and exhaust hot air recirculation with and without exhaust hot air circulation. Performance indicators such as drying rate, coefficient of performance, heat utilization factor, and drying efficiency have been evaluated. A satisfactory drying effect is produced by employing an electric coil at night to raise the temperature within the drying chamber to a maximum of 66.7°C. It is observed that the drying rate in the case of forced convection type hybrid solar dryer is higher when compared to natural convection type and open sun drying. Thus, solar drying is a hygienic process without negative environmental externalities and is most suitable in food processing industries.

Authors: Singha Prosenjit , Sankar Dasgupta Mani , Bhattacharyya Souvik , Hafner Armin 
Published: September 2024

Abstract
In this study, performance of TEC and TEC-TEG modules for providing subcooling in multi evaporator CO2 booster systems with and without ejector operating at high ambient is explored. Effect on heat recovery potential is also determined. The degree of subcooling explored is from 1K to 5K with TEC. Subcooling decreases heat rejection pressure, which improves cooling COP. For the conventional system, the cooling COP of baseline is 1.57 at 45 °C ambient, which improves to a maximum of 1.68 a 7% increment when 5K subcooling with externally powered TEC is implemented. Further, power required for 1K subcooling can be generated using TEG, leading to an increment in COP to 1.623, a 3.2% improvement. For the ejector system the baseline has a cooling COP of 1.9, which improves to 2 with 5K subcooling when TEC is used. In this case also TEG is able to supply the power of 1K subcooling to TEC that results in performance improvement around 3.2%.

Published: September 2024

Abstract
The furnace is an essential part of any industrial process. It is worked between low to high temperature ranges. Refractory is required for that purpose due to high heat energy sustainability. The purpose of this experimental investigation was to determine the effects of different temperatures on an installed furnace by manipulating the arrangement of metallic anchors. The results obtained by experimentally have been also validated by using the ANSYS R 17.1 programme. This testing allows for the generation of data and analysis for various monolithic structures throughout the course of several heating and cooling cycles. It calculated the refractory’s liner thermal expansion coefficient and that of implanted in the material. Additionally, strain and real thermal stress in refractory were determined at increased temperatures. Results revealed that the strain in metallic anchors has been increased by 70.7% than the strain in refractory in temperature range 44-275°C. Also, the temperature stress on the refractory-embedded anchor and the real expansion needs may be better measured with this experiment.
