Published: May 2023

In recent years, laser engraving has received widespread attention as a convenient, efficient, and programmable method, which has enabled the obtaining of high-quality porous graphene from various precursors. Laser engraving is often used to fabricate the dielectric layer with micro-structure for capacitive pressure sensors, however, the usual choice of electrodes remains poorly flexible metal electrodes, which greatly limits the overall flexibility of the sensors. In this work, we propose a flexible capacitive pressure sensor made entirely of thermoplastic polyurethane (TPU) and laser-induced graphene (LIG) derived from wood. The capacitive pressure sensor consisted of a flexible LIG/TPU electrode (LTE), a LIG/TPU electrode with micro hole array, and dielectric layer of TPU with micro-cone array molded from laser-engraved hole array on wood, which provided high sensitivity (0.11 kPa-1), ultra-wide pressure detection range (100Pa to 1.4MPa), fast response (~300 ms) and good stability (>4000 cycles, at 0-35 kPa). We believe that our research makes a significant contribution to the literature because the easily available materials derived from wood and overall consistent flexibility meet the requirements of flexible electronic devices.

The study of phytotherapy in dentistry is relevant due to the low occurrence of research in the treatment of oral pathologies, such as caries and periodontal disease. Thus, the aim of this research was to characterize the chemical composition of extracts from the leaves of Couroupita guianensis Aubl, including toxicological evaluation and the antioxidant and antimicrobial potential against Staphylococcus aureus, Streptococcus mutans and Candida albicans. Three extracts were prepared using assisted ultrasound, originating the Crude Ultrasound Extract (CUE) and Soxhlet apparatus, originating the Crude Soxhlet Extract (CSE) and the Ethanol Soxhlet Extract (ESE). In the analysis of the chemical composition, the presence of flavonoids, tannins and saponins were detected. LC-DAD analysis revealed the presence of caffeic acid, sinapic acid, rutin, quercetin, luteolin, kaempferol and apigenin in all extracts. In the GC-MS analysis, stigmasterol and β-sitosterol were identified in CUE and CSE. The antioxidant potentials, determined by the DPPH• and ABTS•+ methods, the ESE showed higher antioxidant activity (2.98 ± 0.96 and 4.93 ± 0.90, respectively). In the evaluation of toxicity, the CUE 50µg/mL and the ESE 50 µg/mL presented growth stimulation of Allium cepa roots. At a concentration of 750µg/mL, all extracts inhibited root growth. None of the extracts showed toxicity against Artemia salina. Antibacterial action was detected in all extracts, mainly against the microorganisms S. aureus and S. mutans; however, the antifungal action against C. albicans was not detected. From the results, the extracts of C. guianensis have therapeutic potential for use in the control of microorganisms in the oral microbiota.

Authors: Holl Elena , Oskina Anastasia , Baier Urs , Lemmer Andreas
Published: May 2023

The increased demand for resources and energy that is developing with rising global consumption represents a key challenge for our generation. Biogas production can contribute to sustainable energy production and closing nutrient cycles using organic residues or as part of a utilization cascade in the case of energy crops. Compared to hydrogen (H2), biogas with a high methane (CH4) content can be fed into the gas grid without restrictions. For this purpose, the CH4 content of the biogas must be increased from 52 to 60 % after anaerobic digestion to more than 96 %. In this study, biological hydrogen methanation (BHM) in trickling-bed reactors (TBR) is used to upgrade biogas. Design of experiments (DoE) is used to determine the optimal process parameters. The performance of the reactors is stable under all given conditions, reaching a “low” gas grid quality of over 90 %. The highest CH4 content of 95.626 ± 0.563 % is achieved at 55 °C and 4 bar, with a methane formation rate (MFR) of 5.111 ± 0.167 m³/(m³·d). The process performance is highly dependent on the H2:CO2 ratio in the educts, which should be as close as possible to the stochiometric ratio of 4. In conclusion, BHM is a viable approach to upgrade biogas to biomethane quality and can contribute to a sustainable energy grid.

Published: May 2023

A novel synthetic strategy is disclosed to prepare a new class of metalorganic copolymers which contain iron(II) clathrochelate building blocks by employing a mild and cost-effective copper-catalyzed [4 + 2] cyclobenzannulation reaction, using three specially designed diethynyl iron(II) clathrochelate synthons. The target copolymers CBP1-3 were isolated in high purity and excellent yields as proven by their structural and photophysical characterization, namely, Fourier transform infrared (FTIR), X-ray photoelectron spectroscopy (XPS) and UV-vis absorption and emission spectroscopies. Thermogravimetric analysis (TGA) of CBP1-3 reveals excellent chemical stability. Investigation of the adsorption properties of the target copolymers towards the carcinogenic methyl red dye from aqueous solution reveals a quantitative uptake in 30 minutes. Isothermal adsorption studies disclose that methyl red uptake from aqueous solution follows Langmuir model for all the target copolymers reaching a maximum adsorption capacity (qm) of 431 mg g‒1, whereas kinetic investigation reveals that the adsorption follows pseudo first-order with an equilibrium adsorption capacity (qe,cal) of 79.35 mg g‒1 and whose sorption property was sustained even after its reuse several times.
Similarity of Heterogeneous Kinetics to Delay of Double Layer Capacitance by Chronoamperometry
Authors: Liu Yuanyuan , Aoki Koichi Jeremiah , Chen Jingyuan
Published: May 2023

Chronoamperometric curves of the oxidation of a ferrocenyl derivative by the potential step showed diffusion controlled-like currents less than the Cottrell's equation at a platinum wire electrode. The lower deviation cannot be explained by the Butler-Volmer heterogeneous kinetics, but was ascribed to the negatively capacitive current associated with the redox reaction. The deviation at the fully oxidized potential corresponds to the non-zero concentration at the electrode surface, which cannot be predicted from the Nernst equation. The Nernst equation expresses the relationship of the potential with the activity at the electrode surface rather than the concentration. The diffusion equation provides the relation of the current with the surface concentration rather than the activity. The negative capacitance or the non-zero concentration may arise from structure formation on the electrode owing to the dipole-dipole interaction, which is similar to the generation of the double layer capacitance including frequency dispersion. On this concept, we derive here expressions for the lowered diffusion-controlled current and the time-dependent surface concentration. The negatively capacitive current shows the time-dependence of t-0.9, which is similar to the decay of the double layer capacitive currents. The surface concentration decays with the t-0.4-dependence.

Published: May 2023

Bio-based packaging materials and efficient drug delivery systems are gaining attention, carboxymethyl cellulose (CMC) is one of the most soluble cellulose derivatives, is a good candidate material due to its biocompatibility, biodegradability, and reproducibility. However, CMC-based films are lack of sufficient mechanical properties, limiting its widespread application. In this paper, the molecular interactions between CMC and additives with different molecular structures have been studied with rheological method. The additives are chitosan and cellulose derivatives including O-carboxymethylated chitosan (O-CMCh), N-2-hydroxypropyl-3-trimethylammonium-O-carboxymethyl chitosan (HTCMCh), hydroxypropyltrimethyl ammonium chloride chitosan (HACC), cellulose nanofibers (CNC), and cellulose nanofibers (CNF). The influencing factors, such as molecular structure, concentration of additives and temperature on the rheological properties were studied, which results revealed the information intermolecular interactions. Based on the rheological properties, several systems were selected to prepare films, which show very good transparency, wettability, mechanical properties, biodegradability, and cytotoxicity. These good characteristics of the selected films also proved the good biocompatibility of CMC and chitosan and cellulose derivatives. This work will provide an idea to prepare CMC-based food packaging and effective drug delivery materials with specific properties.

Published: May 2023

Shallow landslides pose serious threats to human existence and economic development, especially in the Himalayan areas. Landslide susceptibility mapping (LSM) is a proven way for minimizing the hazard and risk of landslides. Modeling as an essential step, various algorithms have been applied to LSM. In this study, information value (IV) and logistic regression (LR) were selected as representatives of the conventional algorithms, categorical boosting (CatBoost) and conventional neural networks (CNN) as the advanced algorithms, for LSM in Yadong county, and their performance was compared. To begin with, 496 historical landslide events were compiled into a landslide inventory map, followed by a list of 11 conditioning factors, forming a data set. Secondly, the data set was randomly divided into two parts, 80% of which was used for modeling and 20% for validation. Finally, the area under the curve (AUC) and statistical metrics were applied to validate and compare the performance of the models. The results showed that the CNN model performed the best (AUC 0.974 and accuracy=93.3%), while the LR model performed the worst (AUC 0.974 and accuracy=93.3%) and CatBoost model performed better (AUC 0.974 and accuracy=93.3%). Besides, the LSM constructed by the CNN model did a more reasonable prediction of the distribution of susceptible areas. As for feature selection, did a more detailed analysis of conditioning factors but the results were uncertain. The result analyzed by GI may be more reliable but fluctuates with the amount of data. The conclusion reveals that the accuracy of LSM can be further improved with the advancement of algorithms, by determining more representative features, which serve as a more effective guide for land use planning in the study area or other highlands where landslides are frequent.

Published: May 2023

Human motion forecasting is a necessary variable to analyze human motion concerning the safety system of the autonomous system that could be used in many applications, such as in auto-driving vehicles, auto-pilot logistics delivery, and gait analysis in the medical field. At the same time, many types of research have been conducted on 3D human motion prediction for short-term and long-term goals. This paper proposes human motion forecasting in the 2D plane as a reliable alternative in motion capture of the RGB camera attached to the devices. We proposed a method, the time series self-attention approach to generate the next future human motion in the short-term of 400 milliseconds and long-term of 1,000 milliseconds, resulting that the model could predict human motion with a slight error of 23.51 pixels for short-term prediction and 10.3 pixels for long-term prediction on average compared to the ground truth in the quantitative and qualitative evaluation. Our method outperformed the LSTM and GRU models on the Human3.6M dataset based on the MPJPE and MPJVE metrics. The average loss of correct key points varied based on the tolerance value. Our method performed better within the 50 pixels tolerance. In addition, our method is tested by images without key point annotations using OpenPose as the pose estimation method. Resulting, our method could predict well the position of the human but could not predict well for the human body pose. This research is a new baseline for the 2D human motion prediction using the Human3.6M dataset.

Published: May 2023

Case:

A 33-year-old woman with back pain and radiculopathy had presented with bilateral ankle weakness. MRI showed an intramedullary conus lesion suggestive of neoplasm, but posterior midline durotomy revealed only pus. Pus samples showed Staphylococcus aureus, which was treated with 6 weeks of antibiotics. Two-year follow-up showed complete neurological recovery with no clinicoradiological signs of recurrence.

Conclusion:

Usually, intramedullary spinal cord abscess (ISCA) has an acute presentation and warrants an emergent line of treatment with a risk of mortality. Very rarely chronic ISCA can mimic intramedullary spinal cord tumor. It is the first case reported in the literature of chronic ISCA mimicking conus IMST.

Published: May 2023

This article aims to examine the resilience of moderate Muslims in the midst of the reality of the post truth virus that has spread today. The purpose of this research is to find out the typology, theory and practice of moderate Islam in the post-truth era in Indonesia. The approach used is qualitative and by using descriptive analysis methods to study various data sources: from books, journals, scientific works, newspapers, and so on that have a relationship with the theme of discussion. The results of the study show that the typology of moderate Islam refers to those who reject the application of violence as a line of ideology and struggle. The theory of moderate Islam or wasatiyyah Islam has emerged and developed in three historical periods: 1) the ta'sis period (the formation period); 2) tathwir period (development period); 3) the period of tahdits (modernization). The practice of moderate Islam or wasatiyyah Islam in the post-truth era is fused into three scopes of lines of action, including: 1) epistemological lines, moderate Islam is not only inclined to one methodological door in obtaining the truth, but uses various sides of approach to obtain factual truth, so it is less likely to be exposed to hoaxes in the post truth era; 2) the ontological line, the existence of Islamic wasat}iyyah is also a response to cases of stigmatizing Islamophobia in Indonesia; 3) the axiological line, the dimensions of wisdom and wisdom values wrapped in the concepts of tasamuh (tolerance), ta'adul (fair), tawazun (balanced) in moderate Islam, are very effectively applied in the post truth era to fight hoaxes and doctrines of extremist acts that terrorist groups continue to do today.

Published: May 2023

Background: WHO has declared Infertility as the fifth-highest serious global disability with prevalence of approximately 22% in Pakistan; 80% due to polycystic ovarian syndrome (PCOS). PCOS is characterized by “the presence of any two out of three criteria, that is oligo and/or anovulation, excess androgen activity and/or polycystic ovarian morphology on ultrasound”. Vitamin D deficiency (VDD) [serum 25(OH) D <20 ng/ml] is vital for female health and becoming public health problem even in sun-drenched cities. With high prevalence (58%) of VDD in Pakistani PCOS. The hypothesis: “VD supplementation can improve fertility by correcting in IR, ovulatory dysfunction, endometrial thickness and hyperandrogenism in primary infertile PCOS patients of our population”.
We aim to evaluate impact of oral VD supplementation on fertility potential of VDD PCOS (VD <20 ng/ml) in a 2-years randomized clinical trial; Group-1 VDD control PCOS (n=100) and Group-2 VDD intervention group (n=100). Group-1will receive 1.5 g/day metformin therapy for 24 weeks. Group-2 will be given 50,000 I.U of VD once weekly for 8 weeks, followed by 50,000 I.U once every fortnight from 9- 24 weeks plus metformin therapy.
Impact will be assessed by comparing trans-vaginal ultrasound (TVS; Day 12) at the start with TVS at end point (24 weeks) to observe change in dominantfollicle size (≥14 mm) and endometrial thickness (≥8 mm).
Discussion: The proposed interventions will help to evaluate the impact of vitamin D supplementation on follicular maturation and endometrial thickness and PCOS parameters including lipid index and insulin resistance.

Published: May 2023

The attainment of a competitive advantage can be facilitated by the presence of a vendor who is both effective and efficient. The process of selecting a vendor is a complex decision-making task that entails consideration of multiple quantitative and qualitative factors. The objective of this study is to minimise the net ordering cost, transportation cost, and late deliveries. When examining the various circumstances of existence, it is impossible to make anticipatory prognostications. The utilisation of Interval type-2 trapezoidal fuzzy numbers has been employed to effectively demonstrate the presence of uncertainty in the input parameters. A precise equivalent form has been derived through the calculation of the expected value. Exponential smoothing forecasting analysis has been utilised to ascertain the precise demand for the product in order to mitigate the risk of shortages and consequent financial losses. Ultimately, an effective methodology utilising fuzzy goal programming has been employed to attain a mutually satisfactory solution. The proposed methodology has been elucidated through the addition of a numerical illustration of its underlying concepts.

Published: May 2023

The September 6, 2018, earthquake in the eastern part of Hokkaido, Japan, caused extensive slope failures in Atsuma-town, Hokkaido, Japan. In this study, the authors performed in-situ investigations, including trenching and portable dynamic cone penetration tests, on weathered fallen pumice sediments, which are one of the causes of the slope failures. In addition, we performed direct box shear tests on undisturbed samples collected from an undisturbed area under various shear conditions to characterize mechanical properties of the soil. The parameters obtained from the mechanical tests were used to evaluate slope stability under normal and seismic conditions with an infinite-length slope model. The results showed that the slopes where seismic failures occurred had a fragile layer from the surface to a depth of approximately 1.5 m, which generally corresponded to the depth of failure. Weathered pumice deposits with extremely high water content existed at the boundary between the weak layer and the basement layer, and their shear strength was velocity dependent. It has been shown that an infinite-length slope stability analysis can be performed by using mechanical parameters for which velocity dependence of horizontal acceleration and shear strength due to seismic motion are accounted for.

Biogas production from livestock manure has been implemented on large farms in many regions for generating energy while curbing air and water pollution that otherwise results from untreated manure. Traditional biogas systems have required subsidies for implementation on large farms, while implementation on small farms remains rare. Using a new non-linear optimization model with validated field data from Southern Brazil, we explore the feasibility of manure-to-energy systems with cooperative collection and energy production. We generate technical designs for several regions while accounting for costs and greenhouse gas emissions. Our results indicate that profitable and environmentally responsible biogas networks are possible for the areas studied. In one case, a consortium of 26 municipalities in Parana, Brazil, may generate 718 million m3 of biomethane while offsetting 10.5 billion kg of CO2 equivalent greenhouse gas annually, with profits up to US$250 million. Results show that municipality-level biomethane production is more profitable than electricity generation and highlight the need for concurrent policy and technical design for enabling viable biomass to energy systems.
Effect of preoperative oral rehydration before cesarean section on ultrasound assessment of gastric volume and intraoperative hemodynamic changes: a randomized controlled trial
Authors: Ijiri Eriko. , Mori Chie. , Sasakawa Tomoki.
Published: May 2023

Background
Cesarean section often requires an urgent transfusion load due to decreased blood pressure after spinal anesthesia. This prospective randomized study aimed to investigate whether a preoperative oral rehydration solution (ORS) stabilized perioperative circulatory dynamics.
Methods
Sixty-three parturients scheduled for cesarean section under combined spinal epidural anesthesia (CSEA) were randomly allocated to one of three groups: Group O received 500 mL ORS before bedtime and 500 mL 2 h before CSEA, Group M received mineral water instead of ORS, and Group C had no fluid intake (controls). After entering the operating room, stomach size was measured using ultrasound. Blood samples were obtained, and CSEA was induced. Vasopressors were administered when systolic blood pressure was < 90 mmHg or decreased by > 20%. In addition, phenylephrine (0.1 mg) was administered when the heart rate was ≥ 60 bpm, or ephedrine (5 mg) at < 60 bpm. The primary outcome was the total vasopressor dose administered. Secondary outcomes were the cross-sectional area of the stomach antrum, maternal plasma glucose levels, serum sodium levels, total intravenous fluid, bleeding volume, urine volume, operative time, and cord blood gas values after delivery.
Results
The total vasopressor dose was lower in Group O than in Group C (P < 0.05). Group O had lower total dose of phenylephrine than Group C (P < 0.05). There were no significant differences between Group M and other groups. No differences were detected regarding secondary outcomes.
Conclusions
In women scheduled for cesarean section, preoperative ORS stabilized perioperative circulatory dynamics. Neither ORS nor mineral water consumption increased the stomach content volume.

Few studies are available on associations between metal mixture exposures and disrupted thyroid hormone homeostasis. Here we aimed to explore the cross-sectional relationship of blood cells metals with thyroid homeostasis. Among 328 workers from the manganese exposed workers healthy cohort (MEWHC), we detected thyroid function parameters: thyroid stimulating hormone (TSH), total triiodothyronine (TT3), free triiodothyronine (FT3), total tetraiodothyronine (TT4), free tetraiodothyronine (FT4) as well as calculated sum activity of peripheral deiodinases (GD) and thyroid's secretory capacity (GT). Inductively coupled plasma mass spectrometry (ICP-MS) was used to measure 22 metal concentrations in blood cells. Based on the consistent results of least absolute shrinkage and selection operator (LASSO) and Bayesian kernel machine regression (BKMR) analyses, there were significant positive associations between Cu and TSH (beta = 2.016), Fe and FT4 (beta = 0.403), Ti and GD (beta = 0.142), Ni and GD (beta = 0.057) and negative associations between Cu and FT4 (beta = -0.226), Se and GD (beta = -0.332) among the participants. Interestingly, we observed an inverted-U shape relationship between Mg and FT4. Furthermore, we found a synergistic effect between As and Cu on TSH level, whilst antagonistic effects between Ni and Cu as well as Ni and Se on TSH level. We observed a modified effect of iodine status on association between Sr and GD (Pinteraction = 0.026). It suggests metal mixture exposures can alter thyroid homeostasis among the occupational population, possibly through an alteration of deiodinase activity. Validation of these associations and elucidation of underlying mechanisms require further researches in future.

Precipitation is a key component in hydrologic processes. It plays an important role in hydrological modeling and water resource management. However, many regions suffered from limited and data scarcity due to the lack of ground-based rain gauge networks. The main objective of this study is to evaluate and compare three different satellite-based precipitation products (CHIRPS, PERSIANN and GPM) and a reanalysis (ERA5) in semi-arid catchment of Tunisia (Haffouz catchment) against rain-gauge stations records for the period between September 2000 and August 2018. Twelve rain-gauges and two different interpolation methods (Inverse Distance Weight and ordinary kriging) were used to compute a set of interpolated precipitation reference fields. The evaluation was performed at daily, monthly, and yearly time scales and at spatial scales, using different statistical metrics. The results showed that the two interpolation methods give similar and valid precipitation estimates at the catchment scale. According to the different statistical metrics, CHRIPS showed the most satisfactory results followed by PERSIANN which performed well in terms of correlation but overestimated precipitations spatially over the catchment. GPM underestimate the precipitation considerably, but it gives a satisfactory performance temporally. ERA5 shows a very good performance at daily, monthly, and yearly timescale, but it is unable to present the spatial variability distribution of precipitation for this catchment. This study concluded that satellite-based precipitation products can be useful in semi-arid regions and data-scarce catchments, and it may provide less costly alternatives for data-poor regions.
Prolonged dephasing time of ensemble of moiré-trapped interlayer

The moiré superlattices of transition metal dichalcogenide heterobilayers have a pronounced effect on the optical properties of interlayer excitons (IXs) and have been intensively studied in recent years. However, the impact of the moiré potentials on the temporal coherence of the IXs has not yet been investigated in detail. Here, we systematically investigate the coherence properties of both the ensemble of delocalized IXs and the ensemble of localized IXs trapped
in moiré potentials of the hexagonal boron nitride encapsulated WSe2-MoSe2 heterostructures. Our low-temperature first-order correlation measurements show that prolonged T2 dephasing
times with values up to 700 fs can be obtained from the ensemble of localized IXs under moderate pump powers. We observed up to a fourfold increase over the values we obtained from the delocalized IXs, while a twofold over the previously reported values of T2~300 fs from the delocalized IXs. The prolonged values of T2 dephasing times and narrow photoluminescence (PL) line widths for the ensemble of moiré-trapped IXs compared to
delocalized one indicate that dephasing mechanisms caused by exciton-low energy acoustic phonon and exciton-exciton scattering are significantly suppressed due to the presence of
localization potentials. Our results show that ultra-long dephasing times can be expected if the dephasing time measurements are performed with the narrow photoluminescence emission line of a single moiré-trapped IX at a low pump power regime. The prolonged values of IX dephasing times would be critical for the applications of quantum information science and the development of two-dimensional material-based nanolasers.

Laser-driven ion accelerators can deliver high-energy, high peak current beams from relativistic laser plasmas formed in solid-density materials [1, 2]. This innovative concept attracts a lot of attention for various multidisciplinary applications as a compact alternative to conventional accelerators [3]. However, achieving energy levels suitable for applications such as radiation therapy remains a challenge for laser-driven ion accelerators. Here, we report on experimental generation of plasma-accelerated proton beams with a spectrally separated high-energy component of up to 150MeV by irradiating solid-density plastic foil targets with ultrashort laser pulses from a repetitive Petawatt laser. Three-dimensional particle-in-cell simulations reveal that the observed beam parameters result from cascaded acceleration regimes that occur at the onset of relativistically induced transparency. The ultrashort pulse duration allows a rapid sequence of these regimes at highest intensity, enabling proton acceleration to unprecedented energy levels. Target transparency was identified to discriminate the high-performance domain of the acquired data set, making it a suitable feedback parameter for automated laser and target optimisation to enhance stability of plasma accelerators in the future. Ultimately, our results encourage further exploration and application of laser-driven plasmas as compact proton accelerators in the multi-100MeV range.
