Electrofluids with tailored rheoelectrical properties: liquid composites with tuneable network structures as stretchable conductors
Authors: Schmidt Dominik , Kraus Tobias , Gonzalez-Garcia Lola 
Published: July 2023

Abstract
Flexible and stretchable electronics require both sensing elements and stretching-insensitive electrical connections. Conductive polymer composites and liquid metal structures are highly deformable but strongly change their conductivity upon elongation. Macroscopic Kirigami structures combine stretchability with constant conductivity, but their use is limited by geometrical restraints. Here, we introduce concentrated conductive particle suspensions based on Carbon Black as conductive “Electrofluid”. When using incompatible solvents, large agglomerates form that reduce the electrical percolation threshold by one order of magnitude and act as microscopic Kirigami-like structures with very small gauge factors < 0.4. In compatible solvents, well-dispersed fillers exhibit high percolation thresholds, high stiffness, and positive piezoresistivity (gauge factor > 2). Electrofluids enable the rational design of sustainable soft electronics components by simple solvent choice and can be used both as sensor and electrode materials, as we demonstrate.

Published: July 2023

Abstract
The viscoelastic damping layer is highly effective in vibration control of a sandwich circular cylindrical shell. In order to optimize the parameters of the structure, it is indeed essential to investigate an analytical method. Firstly, using the wave propagation approach in conjunction with the Flügge thin-shell theory, the acoustic-structure coupling equations of the analytical model are derived. After considering the boundary and media conditions, the expressions for displacements can be solved. Secondly, considering three kinds of media conditions including liquid-filled, underwater immersion, and bilateral underwater immersion, the accuracy of the analytical model is verified by comparing the vibtation acceleration level with numerical results. Finally, the comparative experiments are carried out, which further verify the accuracy of the analytical model. In addition, according to the experimental results the constrained layer damping has an evident damping effect on the circular cylindrical shell.

Abstract

Porous materials are often added to TiO2 photocatalysts for their superior surface area and reaction rate. Separation and recovery of spent photocatalysts is a challenge for treating industrial dye wastewater with photocatalysts to prevent environmental contamination. The objective of this research was to create a TiO2/BP composite using sol-gel technique, with the purpose of improving its effectiveness in treating wastewater containing MG dye and facilitating its separation. The synthesized TiO2/BP composite was characterized using field emission transmission electron microscopy (FESEM), energy dispersive X-ray (EDX) analysis, diffuse reflectance spectroscopy (DRS UV–vis), photoluminescence spectra (PL), and Brunauer–Emmett–Teller (BET) specific surface area and porosity analysis. Subsequently, the TiO2/BP composite that was synthesized was tested for photoactivity and compared to bare TiO2 particles. The outcomes indicated that the TiO2/BP photocatalyst had a significant boost in photocatalytic activity for decolorizing MG dye and was 3 times faster than the bare TiO2 under visible light. The results from the recyclability test showed that it maintained consistent performance for up to 4 cycles. This showed that the porous material-based photocatalytic composite has a potential application in wastewater treatment and is expected to have a broad application in wastewater treatment.
A comparative study of statistical and machine learning models on carbon dioxide emissions prediction of China
Authors: Li Xiangqian , Zhang Xiaoxiao 
Published: July 2023

Abstract
The rapid growth of carbon dioxide (\({\text{C}\text{O}}_{2}\)) emissions is the primary cause of global warming, which not only poses a significant threat to human survival, but also has a profound impact on the global ecosystem. Consequently, it is crucial to accurately predict and effectively control \({\text{C}\text{O}}_{2}\) emissions in a timely manner to provide guidance for emission mitigation measures. This paper aims to select the best prediction model for near-real-time daily \({\text{C}\text{O}}_{2}\) emissions in China. The prediction models are based on univariate daily time-series data spanning January 1st, 2020 to September 30st, 2022. Six models are proposed, including three statistical models: Grey prediction (GM(1,1)), autoregressive integrated moving average (ARIMA) and seasonal autoregressive integrated moving average with exogenous factors (SARIMAX); and three machine learning models: artificial neural network (ANN), random forest (RF) and long short term memory (LSTM). The performance of these six models is evaluated using five criteria: Mean Squared Error (MSE), Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE) and Coefficient of Determination (\({\text{R}}^{2}\)). The results indicate that the three machine learning models outperform the three statistical models. Among them, the LSTM model demonstrates the best performance across all five criteria for daily \({\text{C}\text{O}}_{2}\) emissions prediction, with an MSE value of 3.5179e-04, an RMSE value of 0.0187, an MAE value of 0.0140, an MAPE value of 14.8291%, an \({\text{R}}^{2}\) value of 0.9844. Therefore, LSTM model is suggested as one of the most suitable models for near-real-time daily \({\text{C}\text{O}}_{2}\) emissions prediction based on the provided daily time series data. Finally, based on the study’s results, several policy recommendations are presented to various departments in China for reducing carbon emissions.

Abstract
Background: The SafeBoosC project aims to test the clinical value of non-invasive cerebral oximetry by near-infrared spectroscopy in newborn infants. The purpose is to establish whether cerebral oximetry can be used to save newborn infants’ lives and brains or not. Newborns contribute heavily to total childhood mortality and neonatal brain damage is the cause of a large part of handicaps such as cerebral palsy. The objective of the SafeBoosC-IIIv trial is to evaluate the benefits and harms of cerebral oximetry added to usual care versus usual care in mechanically ventilated newborns.
Methods/design: SafeBoosC-IIIv is an investigator-initiated, multinational, randomised, pragmatic phase-III clinical trial. The inclusion criteria will be newborns with a gestational age more than 28+0 weeks; postnatal age less than 28 days; predicted to require mechanical ventilation for at least 24 hours; and prior informed consent from the parents or deferred consent or absence of opt-out. The exclusion criteria will be no available cerebral oximeter; suspicion of or confirmed brain injury or disorder; or congenital heart disease likely to require surgery.
A total of 3000 participants will be randomised in 60 neonatal intensive care units from 16 countries, in a 1:1 allocation ratio to cerebral oximetry versus usual care. Participants in the cerebral oximetry group will undergo cerebral oximetry monitoring during mechanical ventilation in the neonatal intensive care unit for as long as deemed useful by the treating physician or until 28 days of life. The participants in the cerebral oximetry group will be treated according to the SafeBoosC treatment guideline. Participants in the usual care group will not receive cerebral oximetry and will receive usual care. There aretwo co-primary outcomes: 1) a composite of death from any cause or moderate to severe neurodevelopmental disability at two years of corrected age and 2) the non-verbal cognitive score of The Parent Report of Children’s Abilities-Revised (PARCA-R) at two years of corrected age.
Discussion: There is need for a randomised clinical trial to evaluate cerebral oximetry added to usual care versus usual care in mechanically ventilated newborns.

Abstract
Podophyllotoxin (PTOX) is a natural antiviral, antirheumatic and anticancer molecule but its chemical synthesis is expensive. The present study aimed to develop and validate an analytical method by HPLC for the quantification of PTOX in roots of Hyptis suaveolens, as well as to evaluate the culture of its roots in vitro in liquid medium supplement with different concentrations of Indole-3-butyric acid (IBA), 1-Naphthaleneacetic acid (NAA), vitamins and myo-inositol. The analytical method was developed and validated. Root culture was used for biomass production and PTOX content was quantified using the developed analytical method after successful validation. The parameters that confirmed the analytical method were selectivity (peak purity: > 99%), system suitability (Rs = 2.92; N = 7064; k = 1.23; As = 1.31; DPR = 0.61%), intra-day and inter-day precision (DPR = 2.43% and 2.96%, respectively), linearity (R² = 0.997), recovery percentage (90.47–101.85%), limit of quantification (5.25 ng) and limit of detection (0.5 ng). Root culture in MS medium containing 1 mg L-1 IBA + 0.5 mg L-1 NAA showed the highest root dry weight (248.76 mg) and the highest PTOX concentration in the root (179, 97 µg-1). The vitamins and myo-inositol in the medium produced 198.88 mg of root dry weight and 6.01 µg g-1 of PTOX. The roots cultured in liquid MS medium supplemented with 1 mg L-1 of IBA + 0.5 mg L-1 of NAA maximized the root biomass and PTOX content. The adequate balance of vitamin and myo-inositol supplementation in liquid MS culture medium increased the production of root dry weight and PTOX accumulation.

Abstract
This study investigates the association of blood and semen Bisfenol A (BPA) levels of the male partner on the reproductive outcome in intracytoplasmic sperm injection treatment cycles (ICSI). For this prospective study (clinicaltrials.gov identifier: NCT02703584) blood and semen samples of the male partner of the seventy five women who had ICSI were analyzed. The study group consisted of men who had ICSI for male factor infertility other than azoospermia, while men with normal spermiogram whose partnets underwent ICSI due to tubal factor infertility were taken as the study group. Habitual consumption of drinking water from plastic carboys/bottles (PBW) at home was also questioned in both groups as it was considered as chronic BPA exposure. The association of ICSI outcome with blood BPA (bBPA) and semen BPA (sBPA) levels were analyzed in both groups. In the patients who failed to get pregnant, bBPA levels of the male partner was statistically significantly higher then the ones who achieved pregnancy in both groups. Embryo development arrest was found significantly higher in the patients who have high sBPA levels. No significant correlation was found between sperm parameters and bBPA levels in both groups. A negative correlation was found between sBPA levels and total sperm count and progressive sperm motility in men who consumed PBW. Although, PBW BPA levels were not different, bBPA levels were found to be significantly lower in those who consumed tap water than those who used PBW. Elevated serum BPA level was associated with a significantly lower clinical pregnancy rate.

Abstract
Background: The incidence of postoperative sore throat (POST) after tracheal intubation using double-lumen endobronchial tubes (DLTs) is higher in patients with prior severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection than in the general population. This prospective trial was conducted to determine whether thermal softening of DLTs could decrease the incidence of POST or other airway injuries in patients with prior SARS-CoV-2 infection.
Methods:A total of 120 patients with prior SARS-CoV-2 infection undergoing thoracoscopic surgery were randomly assigned to two groups (n=60 each). In the thermal softening group, the distal portion of the DLT was placed in thermostatic saline (50°C) for 10 min before endotracheal intubation. In the control group, the distal portion of the DLT was placed in room temperature saline for 10 min before endotracheal intubation. The incidence and severity of POST and hoarseness were assessed at 1,6 and 24 h postoperatively. The primary outcomes were the incidence and severity of POST at 6 h postoperatively. The secondary outcomes were the incidence and severity of hoarseness, vocal cord and tracheal injuries, and hemodynamic changes in patients at intubation.
Results:The incidence of POSTat 6 h postoperatively was greater in the control group than in the thermal softening group [41 (68%) vs. 22 (37%), P=0.001]. The overall incidence of POSTat 24 h postoperatively was greater in the control group than in the thermal softening group [46 (76%) vs. 24 (40%), P< 0.001].The overall incidence of tracheal injuries was also greater in the control group than in the thermal softening group (P=0.016). Vocal cord injuries occurred more frequently in the control groupthan in the thermal softening group (P=0.006).
Conclusion: Thermal softening of DLTs before intubation can reduce the incidence of POST and airway injuries in patients with prior SARS-CoV-2 infection undergoing DLT insertion

Published: July 2023

Abstract
Background and Purpose
Non-O blood types are known to be associated with thromboembolic complications (TECs) in population-based studies. TECs are known drivers of morbidity and mortality in intracerebral hemorrhage (ICH) patients, yet the relationships of blood type on TECs in this patient population are unknown. We sought to explore the relationships between ABO blood type and TECs in ICH patients.
Methods
Consecutive adult ICH patients enrolled into a prospective observational cohort study with available ABO blood type data were analyzed. Patients with cancer history, prior thromboembolism, and baseline laboratory evidence of coagulopathy were excluded. The primary exposure variable was blood type (non-O versus O). The primary outcome was composite TEC, defined as pulmonary embolism, deep venous thrombosis, ischemic stroke or myocardial infarction, during the hospital stay. Relationships between blood type, TECs and clinical outcomes were separately assessed using logistic regression models after adjusting for sex, ethnicity and ICH score.
Results
Of 301 ICH patients included for analysis, 44% were non-O blood type. Non-O blood type was associated with higher admission GCS and lower ICH score on baseline comparisons. We identified TECs in 11.6% of our overall patient cohort. Although TECs were identified in 9.9% of non-O blood type patients compared to 13.0% in O blood type patients, we did not identify a significant relationship of non-O blood type with TECs (adjusted OR = 0.776, 95%CI: 0.348–1.733, p = 0.537). The prevalence of specific TECs were also comparable in unadjusted and adjusted analyses between the two cohorts. In additional analyses, we identified that TECs were associated with poor 90-day mRS (adjusted OR = 3.452, 95% CI: 1.001–11.903, p = 0.050). We did not identify relationships between ABO blood type and poor 90-day mRS (adjusted OR = 0.994, 95% CI:0.465–2.128, p = 0.988).
Conclusions
We identified that TECs were associated with worse ICH outcomes. However, we did not identify relationships in ABO blood type and TECs. Further work is required to assess best diagnostic and prophylactic and treatment strategies for TECs to improve ICH outcomes.
Determining the failure mechanism and analyzing numerical stability of a Loess slope in seismic zones: a case study
Authors: Yazarloo Rasool , Nabizadeh Farhad 
Published: July 2023

Abstract
In this paper, with a set of engineering tools including field visits, laboratory experiments, geophysical methods, and numerical simulations, it’s been studied and determined the mechanism of the landslide in AghEmam village, northeast of Iran in Golestan Province. By performing a series of triaxial tests, the mechanical properties of loess soil were calculated, and by performing spectral ratio analysis (H/V) of the microtremor waves, the dynamic properties of the site were determined. The subsurface conditions of the landslide were identified by the high-density resistivity geoelectrical method. The results showed that the output of the numerical simulations carried out by PLAXIS software is in good agreement with the geophysical method and field observations. Based on the results, failure surface of the AghEmam landslide was curved and occurred due to seepage caused by continuous precipitation. With the continuation of precipitation, the loess layer was gradually saturated, and with the formation of a homogeneous flow field, rain directly reached the deep layers; with the dissolution of the cement between the loess grains at the depth, a critical slip surface was formed. The results showed that during the earthquake, stresses were gradually trapped in the slope and facilitated landslide by increasing the horizontal dynamic force. Earthquake also helping seepage and accelerate slide by destroying the porous structure of the loess and creating cracks. Finally, the applying of both precipitation and earthquake factors to the numerical model caused a considerable decrease in the safety factor, which indicates the inevitable occurrence of landslide in such conditions.
Physics Enhanced Sparse Identification of Dynamical Systems with Discontinuous Nonlinearities
Authors: Lathourakis Christos , Cicirello Alice 
Published: July 2023

Abstract

A method is introduced for the identification of the nonlinear governing equations of dynamical systems in the presence of discontinuous and nonsmooth nonlinear forces, such as the ones generated by frictional contacts, based on noisy measurements. The so-called Physics Informed Sparse Identification of Nonlinear Dynamics (PhI-SINDy) builds upon the existing RK4-SINDy identification scheme, incorporating known physics and domain knowledge in three different ways (biases). In this way, it addresses the discontinuous behavior of frictional systems when stick-slip phenomena are observed, which can not be captured by existing state-of-the-art approaches. The potential of PhI-SINDy is highlighted through a plethora of case studies, starting from a simple yet representative Single Degree of Freedom (SDOF) oscillator with a Coulomb friction contact under harmonic load, using both synthetic and experimental noisy measurements. An alternative friction law, namely the Dieterich-Ruina one, is also considered as well as a more realistic excitation time series, which was generated based on the Jonswap spectrum. Lastly, a Multi Degree of Freedom system with single and multiple friction contacts is used as a testbed, showcasing the applicability of PhISINDy to more complicated systems and/or multiple sources of discontinuous nonlinearities.

Published: July 2023

Abstract
Background: Human hydatid disease typically occurs in organs such as the liver and kidney. Primary solitary intramuscular hydatid disease, however, is rare.
Case Presentation: We report a case of a giant muscle hydatid in the lower extremity, with neurological symptoms as the first manifestation. The symptoms specifically manifested as intermittent pain in the right lower extremity and numbness in the sole of the right foot. However, there were no obvious abnormalities detected in electromyography and lumbar MRI. Subsequent ultrasonography and calf MRI showed that the patient had cystic lesions in the calf. The patient was initially diagnosed with a muscle hydatid cyst. Treatment involved complete surgical excision of the lesion, and the diagnosis of a hydatid cyst was confirmed through macroscopic and microscopic histopathological examination after the mass was excised. The patient was given oral albendazole, and no recurrence was observed during the 12 months of follow-up.
Conclusions: This case underscores the importance of considering hydatid disease in the differential diagnosis of soft tissue masses in the muscular system, particularly in endemic areas. Patients may also present with atypical symptoms, such as peripheral nerve symptoms, as their primary complaint.
