Abstract
Background and study aims Evidence for the modes of transmission of SARS-CoV-2 remains controversial. Recently, the potential for airborne spread of SARS-CoV-2 has been stressed. Air circulation in gastrointestinal light source boxes and endoscopes could be implicated in airborne transmission of microorganisms.
Methods The ENDOBOX SC is a 600 × 600 mm cube designed to contain any type of machine used during gastrointestinal endoscopy. It allows for a 100-mm space between a machine and the walls of the ENDOBOX SC. To use the ENDOBOX SC, it is connected to the medical air system and it provides positive flow from the box to the endoscopy room. The ENDOBOX SC uses medical air to inflate the digestive tract and to decrease the temperature induced by the microprocessors or by the lamp. ENDOBOX SC has been investigated in different environments.
Results An endoscopic procedure performed without ventilation was interrupted after 40 minutes to prevent computer damage. During the first 30 minutes, the temperature increased from 18 °C to 31 °C with a LED system. The procedure with fans identified variations in temperature inside the ENDOBOX SC from 21 to 26 °C (± 5 °C) 1 hour after the start of the procedure. The temperature was stable for the next 3 hours.
Conclusions ENDOBOX SC prevents the increase in temperature induced by lamps and processors, allows access to all necessary connections into the endoscopic columns, and creates a sterile and positive pressure volume, which prevents potential contamination from microorganisms.

Published: December 2022

SummaryOzon im Niedrig-Dosis-Konzept wirkt als Bioregulator: Bei chronisch oxidativem Stress werden Antioxidantien (via Regulation der Kernfaktoren wie Nrf2 und NFkB) hochreguliert, der oxidative Stress sinkt und das GSH/GSSG-Gleichgewicht wird reorganisiert, das Immunsystem moduliert.Mit diesem grundlegenden Mechanismus erweist sich systemisch verabreichtes Ozon (Große Ozon-Eigenblutbehandlung, GEB, oder Rektale Insufflation, RI) als interessante, nützliche und evidenzbasierte Therapie in der Redoxmedizin, insbesondere in Prävention und Rekonvaleszenz sowie bei chronischen Entzündungsprozessen.

Published: December 2022

AbstractEumycetomas of craniocerebral are rare, and we report an extraordinary case of maduramycosis involving brain and skull bone in a middle-aged male who presented with complaints of headache, behavioral abnormalities, and memory disturbances for 3 months. Imaging showed a frontal lesion. It was mistaken for a tumor clinically and radiologically. Craniocerebral eumycetoma usually presents as a mass on the scalp with sinuses. Our case presented as a brain tumor without a soft tissue mass or discharging sinuses. It is essential to keep in mind this mode of presentation, and only a biopsy will aid in diagnosis.
Investigating phosphate-adsorption behaviour on a real ferrallitic-ferritic soil using a pluralistic approach under non-controlled conditions
Authors: Rosello C. H. , Pratt C. , Meyer M. , Pagand P. 
Published: December 2022

Context Ferralsols, which cover approximately 6% of the Earth’s continental surface, have unique phosphorus (P) retention properties. Aims The research investigates P adsorption properties under non-controlled conditions on lateritic soil samples, combining different methodological approaches. Methods Ferralsol samples were analysed using (1) adsorption kinetics and capacities (wet chemical experiment methods), (2) scanning electron microscopy (SEM) and transmission electron microscopy and (3) attenuated transmission reflectance-Fourier transform infrared spectroscopy (ATR-FTIR). Key results Wet chemical experiments accord with previous studies on lateritic soils where chemisorption mechanisms govern P adsorption. Further, P adsorption appears to affect soil particles’ structural stability and release of iron (Fe) species in solution. SEM mapping confirmed the location of P compounds in Fe-rich areas. ATR-FTIR identified two inner-sphere complexes: monodentate (FeO)PO2(OH) and bidentate (FeO)2PO(OH) at wavenumber positions 958 ± 5, 1042 ± 5 and 1095 ± 8 cm−1; and 930 ± 5, 983 ± 10, 1005 ± 5 and 1122 ± 9 cm−1, respectively. Also, a band centred at 1030 ± 4 cm−1 suggested evidence of ternary complexes for P concentrations above 500 mg P/L. Combined methods suggested the potential involvement of redox mechanisms and other ionic species in the formation and types of phosphate surface complexes. Conclusions Our approach builds on previous work in this field by showing evidence of complex ionic interactions governing P retention on lateritic soils. Novel insights are evidence of fluctuations in physical and chemical factors with phosphate adsorption and suggestion of inner-sphere and ternary surface complexation mechanisms. Implications Given the wide global distribution of lateritic Ferralsols, our findings have important implications for key emerging challenges relating to P cycling for crop production and environmental impact.
Does creatine supplementation affect recovery speed of impulse above critical torque?

Published: December 2022

ABSTRACTWe previously reported that creatine supplementation improved intermittent isometric exercise performance by augmenting the total impulse performed above end‐test torque (total IET′). However, our previous analyses did not enable mechanistic assessments. The objective of this study was to determine if creatine supplementation affected the IET′ speed of recovery. To achieve this objective, we retrospectively analyzed our data using the IET′ balance model to determine the time constant for the recovery of IET′ (τIET′). Sixteen men were randomly allocated into creatine (N = 8) or placebo (N = 8) groups. Prior to supplementation, participants performed quadriceps all‐out exercise to determine end‐test torque (ET) and IETʹ. Participants then performed quadriceps exercise at ET + 10% until task‐failure before supplementation (Baseline), until task‐failure after supplementation (Creatine or Placebo), and until the Baseline time after supplementation (Creatine‐ or Placebo‐Isotime). τIET′ was faster than Baseline for Creatine (669 ± 98 vs 470 ± 66 s), but not Placebo (792 ± 166 vs 786 ± 161 s). The creatine‐induced change in τIET′ was inversely correlated with the creatine‐induced changes in both the rate of peripheral fatigue development and time to task‐failure. τIET′ was inversely correlated with total IET′ and ET in all conditions, but creatine supplementation shifted this relationship such that τIET′ was faster for a given ET. Creatine supplementation, therefore, sped the recovery of IET′ during intermittent isometric exercise, which was inversely related to the improvement in exercise performance. These findings support that the improvement in exercise performance after creatine supplementation was, at least in part, specific to effects on the physiological mechanisms that determine the IET′ speed of recovery.

Published: December 2022

Abstract
This paper proposes a bilevel optimal scheduling model considering the flexibility and peak shaving benefits of gas-steam combined cycle units, which realizes “thermoelectric decoupling” and the flexibility of the unit by configuring electric boilers, and adds the benefit of peak shaving to the upper model to maximize the profit of the unit. Among them, the upper model is the unit optimal bidding model considering flexibility and peak shaving benefits, and the lower model is the power market-clearing model considering the maximization of social welfare. The bilayer model is transformed into a mixed-integer linear programming problem through KKT conditions and other solution methods. The effectiveness and rationality of the model are verified by the analysis of examples. The results of examples show that “thermoelectric decoupling” and start-stop peak shaving can effectively improve the profit of the gas-steam combined cycle unit and the wind power consumption capacity of the system. Finally, the strategic bidding behavior of gas-steam combined cycle units in different periods of the power market is explored.

Published: December 2022

Abstract
The Active power filter (APF) plays an important role in reducing the harmonic distortion rate of grid current and improving grid stability. However, the APF based on traditional methods such as deadbeat control and hysteresis control has poor tracking accuracy for the load harmonic current, and it is difficult to achieve efficient compensation. In this regard, this paper proposes a current inner loop quasi-proportional resonant (PR) control method to achieve fast-tracking of the compensation current and high control precision. Then, according to the equivalent mathematical model of the three-phase APF in the continuous domain, the parameters of the quasi-PR control method are designed. Finally, the effectiveness of the proposed method is verified by simulation.

Abstract
As the renewable energy installation incerase, self-consistent integrated energy system (IES) is becoming more and more important for power grid. However, the current optimal scheduling strategy of IES lacks of robustness. At the same time, few people have studied the influence of national policies on the optimal dispatch of IES. To solve these problems, an optimal dispatch is presented for IES with the tradable green certificate (TGC) considering PV prediction error based on distributionally robust optimization (DRO). The practicality of the proposed model is verified in the typical IES. Based on the experimental results, the proposed strategy can improve the robustness of the optimal dispatch and improve renewable energy consumption.

Published: December 2022

Abstract
Large-scale integration of variable renewable energy and power electronic device has raised great changes in the physical characteristics of power systems. It is urgent to strengthen system weaknesses in system evolution study. To fill the gap, a generation expansion planning model considering weakness identification and reinforcement is proposed. An efficient outer-inner loop algorithm is designed based on the structure of the model. An IEEE 6-bus test case is carried out to show the effectiveness of the proposed model and methodology. The test case reveals that weakness reinforcement schemes are robust against the worst-case contingency and the unserved demand can be reduced to 20.6% after the weakness reinforcement process.

Abstract
Wheeled mobile robots have a wide range of applications in aerospace, military, industry, medical services, and even entertainment. It is simple in design and easy in fabrication and is widely studied by scholars at home and abroad. However, the path-tracking problem of wheeled mobile robots has also been a key problem inhibiting their development. In this design, the kinematic model of the robot is constructed by using P and feedforward, and a double closed-loop P and feedforward control system is designed. After a trial-and-error method, the appropriate control parameters are obtained. The simul ink function in MATLAB is used to simulate and verify the path-following ability of the method.
Photonic Crystal Design for Bloch Surface Wave Sensing
Authors: Dias Bernardo , de Almeida José M. M. M. , Coelho Luís C. C. 
Published: December 2022

Abstract
Bloch Surface Waves (BSW) consist of electromagnetic modes generated at the interface between a photonic crystal and an isotropic dielectric. This type of surface mode displays sharp resonances and high sensitivity to external refractive index variations, and thus appears to be an ideal candidate for usage in optical sensors. Nevertheless, design and optimization of photonic crystals is not a trivial task and constitutes an ongoing field of research. The sensitivity of BSW in both refractometric and adsorption sensing is calculated analytically using first-order perturbation theory for TE modes, allowing the understanding of how several physical parameters of the photonic crystal influence the sensitivity. Preliminary experimental results are presented, which aim to use the analytical calculations to allow for both refractometric and adsorption sensing in a single photonic crystal structure.
Reservoir computing with nonlinear optical media
Authors: Ferreira Tiago D. , Silva Nuno A. , Silva Duarte , Rosa Carla C. , Guerreiro Ariel 
Published: December 2022

Abstract
Reservoir computing is a versatile approach for implementing physically Recurrent Neural networks which take advantage of a reservoir, consisting of a set of interconnected neurons with temporal dynamics, whose weights and biases are fixed and do not need to be optimized. Instead, the training takes place only at the output layer towards a specific task. One important requirement for these systems to work is nonlinearity, which in optical setups is usually obtained via the saturation of the detection device. In this work, we explore a distinct approach using a photorefractive crystal as the source of the nonlinearity in the reservoir. Furthermore, by leveraging on the time response of the photorefractive media, one can also have the temporal interaction required for such architecture. If we space out in time the propagation of different states, the temporal interaction is lost, and the system can work as an extreme learning machine. This corresponds to a physical implementation of a Feed-Forward Neural Network with a single hidden layer and fixed random weights and biases. Some preliminary results are presented and discussed.
A Low-cost Portable Interrogator for Dynamic Monitoring of Wavelength-Based Sensors

Published: December 2022

Abstract
This paper proposes a low-cost portable interrogator for dynamic monitoring of wavelength-based fiber-optic sensors such as fiber Bragg gratings (FBGs) and Fabry-Perrot interferometers (FPIs). The interrogator is based on a compact solution involving a broadband light source and the spectral convolution between the sensor and a tunable filter. The filtered signal is then acquired by a photodetector where the optical-electrical conversion happens. Additionally, a microcontroller performs three actions: (i) controls the filter tuning, (ii) acquires the photodetector signal, and (iii) sends the data to a single-board computer (SBC). Lastly, the SBC performs further signal processing and displays the sensor data on a graphical user interface. The choice for hardware and software development combined allows for a lost-cost solution that supports monitoring of four channels simultaneously, real-time operation, compatibility with Windows and Linux-based operating systems, dynamic inputs for signal processing, wireless communication with low latency, and portability.

Authors: Pereira Diana , Bierlich Jörg , Kobelke Jens , Ferreira Marta S. 
Published: December 2022

Abstract
The measurement of physical parameters is important in many current applications, since they often rely on these measurands to operate with the due quality and the necessary safety. In this work, a simple and robust optical fiber sensor based on an antiresonant hollow square core fiber (HSCF) is proposed to measure simultaneously temperature, strain, and curvature. The proposed sensor was designed in a transmission configuration where a segment of HSCF, with a 10 mm length, was spliced between two single mode fibers. In this sensor, a cladding modal interference (CMI) and a Mach-Zehnder interference (MZI) are enhanced along with the antiresonance (AR) guidance. All the present mechanisms exhibit different responses towards the physical parameters. For the temperature, sensitivities of 32.8 pm/°C, 18.9 pm/°C, and 15.7 pm/°C were respectively attained for the MZI, AR, and CMI. As for the strain, sensitivities of 0.45 pm/με, -0.93 pm/με, and -2.72 pm/με were acquired for the MZI, AR and CMI respectively. Meanwhile, for the curvature measurements, two regions of analysis were considered. In the first region (0 m−1 - 0.7 m−1) sensitivities of 0.033 nm/m−1, -0.27 nm/m−1, and -2.21 nm/m−1 were achieved, whilst for the second region (0.7 m−1 - 1.5 m−1) sensitivities of 0.067 nm/m−1, -0.63 nm/m−1, and -0.49 nm/m−1 were acquired for the MZI, AR and CMI, respectively.

Published: December 2022

Abstract
Photonic researchers have increasingly exploiting nanotechnology. Due to the advent of numerous prevalent nanosized manufacturing methods that enable adequate shaped nanostructures to be manufactured and investigated as a method of exploiting nano-structured. Owing of the variety of optical modes, hybrid nanostructures that integrate dielectric resonators with plasmonic nanostructures also offer enormous potentials. In this work, we have explored a hybrid coupled nano-structured antenna with stacked lithium tantalate (LiTaO3)/Aluminium oxide (Al2O3) multilayer operating at infrared ranging from 400 nm-2000 nm. Here, the sensitivity response has been explored of the hybrid nano-structured array made up of the gold metal elliptical disk placed on the top of a quartz substrate and excite the different modes in both materials. It shows large electromagnetic confinement at the separation distance (d) of the dimers due to strong surface plasmon resonance (SPR). The influence of the structural dimensions is investigated to optimise the sensitivity of stacked elliptical dimers. The designed hybrid coupled nano-structure with the combination of gold (Au) and Lithium tantalate (LiTaO3) /Aluminium oxide (Al2O3) with h
1 = h
2 = 10 nm each 10 layer exhibits bulk sensitivity (S), which is the spectrum shift unit per refractive index (RI) change in the surrounding medium was calculated to be 730 and 660 nm/RIU with major axis, (a) = 100 nm, minor axis, (b) = 10 nm, separation distance (d) = 10 nm, height, (h) = 100 nm (with or without stacked). The outcomes from the proposed hybrid nanostructure have been compared with a single metallic (only gold) elliptical paired nano-structure to show a significant improvement in the sensitivity using hybrid nano-structure. Depending on these findings, we demonstrated a roughly two-fold increase in sensitivity (S) by utilising a hybrid nano linked nano-structure with respect to identical nano structure, which competes with traditional sensors with the same height, (h) based on localised surface plasmon resonances. Our innovative plasmonic hybrid nanostructures provide a framework for developing plasmonic nanostructures for use in various sensing applications.
Study on characteristics of acoustic signals generated by different DC discharge modes
Authors: XIONG Zilan , WANG Yuqi , LI Mengqi 
Published: December 2022

Abstract
Acoustic signals contain rich discharge information. In this study, the acoustic signal characteristics of transient glow, spark, and glow discharges generated through DC pin–pin discharge were investigated. The signals were analyzed in the time, frequency, and time–frequency domains, and the correlation between the electric and the acoustic signal was studied statistically. The results show that glow discharge does not produce measurable sound signals. For the other modes, with a decrease in the discharge gap, the amplitude of the acoustic signal increases sharply with mode transformation, the short-time average energy becomes higher, and the frequency components are more abundant. Meanwhile, the current pulse and sound pressure pulse have a one-to-one relationship in the transient glow and spark regimes, and they are positively correlated in amplitude. A brief theoretical analysis of the mechanism of plasma sound and the trends of signals in different modes is presented. Essentially, the change in the discharge energy is closely related to the sound generation of the plasma.
