Published: June 2022

Abstract
In this work, phosphorus fractionations (PFs) in the surface, overlying and interstitial water, sediments and two macrophytes (reed and cattail) were investigated in a near-nature constructed wetland. The mechanism of vertical migration and transformation, diffusion flux of sediment and overlying water and the risk of phosphorus release from sediments were studied. The results showed that the occurrence of macrophytes influenced the horizontal and vertical distributions of phosphorus. Reed community area resulted in different orders of TP, TDP and SRP concentrations in the surface, overlying and interstitial water as well as higher removal efficiencies than open water area and cattail community area. Phosphorus distributions in reed community area were closely correlated to the environmental factors and phosphorus in the overlying water were significantly correlated to the biomass and morphological characteristics of reeds (p < 0.01). TP in sediments were positively correlated to the OM contents in both macrophytes free and covered area (p < 0.05) and Org-P was negatively correlated to APA in both open water area (p < 0.05) and reed community area (p < 0.01). Phosphorus diffused from sediment into overlying water due to the positive diffusion flux of sediment-overlying water. The degree of phosphorus saturation (DPS) in macrophytes covered area communities was higher while the phosphorus sorption index (PSI) was lower than that in macrophytes free area. The eutrophication risk index (ERI) of wetland sediment showed the risk of phosphorus released from sediment was high, especially in cattail community area. The results of this study provided references for macrophytes management and removal efficiency improvement in constructed wetlands.

Published: June 2022

Abstract
Deep learning (DL) and reinforcement learning (RL) based methods can efficiently generate offloading strategies for computational offloading problems in mobile edge computing (MEC) environments. However, the rapid movement of vehicles in the vehicular network causes dynamic changes in the network environment, and DL or RL methods require additional training samples and multiple gradient updates before the model converges, which is time-consuming. In this letter, we propose a meta reinforcement learning-based computation task offloading and resource allocation (MRLOA) algorithm for vehicular networks. Specifically, the MRLOA can converge quickly for a new task with a small number of experience and gradient updates based on a pre-trained meta policy. Simulation results show that our proposed algorithm can more quickly adapt to new computational offloading tasks in the vehicular network environment compared to traditional baseline algorithms.
Bacterial degradation of bisphenol A and its analogues: An overview
Authors: Farias Julia de Morais , Krepsky Natascha 
Published: June 2022

Abstract
Bisphenol A (BPA) is one of the most produced synthetic monomers in the world and is widespread in the environment. Due to its adverse effects on life, BPA was replaced by bisphenol analogues (BP). Bacteria can degrade BPA and other bisphenol analogues (BP) diminishing their concentrations in the environment. To summarize the knowledge and contribute to future studies, in this review we surveyed papers on bacterial degradation of twelve different bisphenol analogues published until 2020. A total of 84 original papers from PubMed and Google Scholar were selected for this review. Most of the studies (95.2%, n = 80) on bacterial degradation of bisphenol analogues (BP) focused on bisphenol A (BPA), and then on BPF, and BPS. The number of studies on bacterial degradation of bisphenol analogues increased almost six times from 2000 (n = 2) to 2020 (n = 11). Indigenous microorganisms and the genera Sphingobium and Cupriavidus could degrade several BP. However, few studies focused on Cupriavidus. Biodegradation of BPA does not imply the degradation of other analogues. The acknowledgement of various aspects of BP bacterial biodegradation is vital for choosing the most suitable microorganisms for the bioremediation of a single BP or a mixture of BP.

Published: June 2022

Abstract
A method of friction heating incremental sheet forming (FHISF) is presented with friction heating of rotating tools and sheet metal, which does not necessitate the use of external heating and saves costs. Utilizing orthogonal experimental design, CATIA reverse engineering methods and finite element model (FEM) analysis, the deformation characteristics of AZ31B magnesium alloy FHISF are investigations, which include formability, geometrical accuracy, thickness distribution, Mises stress and plastic strain at various forming stages. The findings reveal that: In FHISF, increasing the spindle speed is the most significant method to improve the formability, and the maximum forming angle is similar to that of other heating-assisted incremental sheet forming can reach 71°. The bending phenomenon appears early in the forming process, causing the upper corner area to have the poorest precision, and the lower corner area to have visible flaws. The actual part sidewall stabilization region is 11% thinner than the theoretically stable thickness. By the establishment of the FEM, observed and predicted the thickness and stress-strain changing trend of the complete FHISF process satisfactorily.

Published: June 2022

Abstract
Objectives: To evaluate the short and long term effects of headgear on the third molar eruption space and the eruption status of the maxillary third molar at the long term follow up. Materials and Methods: Records were collected for 33 Class II cases treated with headgear. Three records were collected: before treatment (T1), after treatment (T2), and at the long term follow up (T3). Three corresponding time points were selected for the control sample. Lateral cephalograms were used to measure the distance from the distal surface of the maxillary first molar to pterygoid vertical (PTV). The third molar status at T3 was categorized into five groups as follows: impacted, extracted, erupted, missing, and formation stage. Results: No significant statistical difference was found between test and control groups for U6-PTV at T1 (p= 0.128) and T3 (p= 0.289). However, a significant statistical difference was found at the end of treatment T2 (p=0.000). Regarding molar status, no significant statistical difference was observed (p= 0.108). Conclusion: Headgear caused a temporary decrease in the U6-PTV distance that was recovered later on. This decrease was not observed in the control group and did not affect the eruption of the third molar. Clinical Relevance: The use of headgear to correct Class II malocclusion does not seem to increase the risk of upper third molar impaction.
From pilot site knowledge via integrated reservoir characterization to utilization perspectives of a deep geothermal reservoir: 3D geological model at the research platform Groß Schönebeck in the Northeast German Basin
Authors: Norden Ben , Bauer Klaus , Krawczyk Charlotte M. 
Published: June 2022

Abstract
The Groß Schönebeck site in the North German Basin serves as research platform for studying the geothermal potential of deeply buried Permian reservoir rocks and the technical feasibility to extract their geothermal heat. The structural setting of the site was investigated in more detail by studying a newly acquired 3D-seismic survey to improve the structural picture that was based on several old 2D seismic lines so far. The new data allows a revision of the geological interpretation of the site, enabling the set-up of a new reservoir model and providing base information for a possible further site development of the Permian and Permo-Carboniferous targets. The 3D seismic of Groß Schönebeck allows for the first time a consistent geological interpretation and model parameterization of the well-studied geothermal site. Main reflector horizons and the corresponding stratigraphic units were mapped and the structural pattern of the subsurface presented in the 8 km x 8 km x 4 km large seismic volume. While some fracture and fault patterns are visible in the upper Zechstein and post-Permian units, formerly hypothesized large offset faults are not present in the Rotliegend reservoir itself. However, a well-established graben-like structure at the top of the Zechstein succession is most likely related to broken anhydritic Zechstein stringers. Most reflectors above the salt show a rather undisturbed pattern. The main reservoir sandstone of the Dethlingen Formation (Rotliegend) was mapped and characterized. The base of the underlying Permo-Carboniferous volcanic rock sequence and hence its thickness could not be depicted reliably from the geophysical data. Based on the new seismic data and the available reconnaissance drilling, logging, and laboratory data of the Groß Schönebeck research site, the thickness and distribution of the sedimentary Rotliegend (with emphasis of the sandy reservoir section) and of the volcanic rock sequence was modelled and parameterized with petrophysical properties (i.e., total and effective porosity, fluid permeability, bulk density, thermal conductivity, thermal diffusivity, and specific heat capacity), providing a more realistic reservoir description. The data and interpretation constitute the basis for a better understanding of the dominating processes at the site and for future measures. Further site development could include a deepening of one well to give evidence on the volcanic rock sequence and consider deviated wells into favourable zones and the design of a fracture-dominated utilization approach.
WITHDRAWN: Drawing-upsetting-extrusion-clinching of high strength steel and aluminum alloy

Published: June 2022

Abstract
To realize good point connection between high-strength steel and aluminum alloy, a process of drawing-upsetting-extrusion-clinching was proposed. First, the sheets were thinning drawn, then the bottom of the protrusion part was extruded, forming the necessary initial interlock, finally the protrusion part was reverse press clinched, forming a certain height of the clinched head. Taking DP980 high strength steel and Al5083 aluminum alloy as the connection objects, using the method of numerical simulation combined with experimental test, the mold was made and the experiment was carried out on the basis of numerical simulation. The experimental results proved the feasibility of the process and the effectiveness of the numerical model. The simulation and experimental results show that the necessary interlock in the drawing-upsetting-extrusion stage is the premise of effective connection. The relative protrusion height should be around 55.6% after reverse-press-clinching. The best comprehensive mechanical properties measured by strength test were shear resistance of 2644N, fatigue life of 24535 times and peel resistance of 1522N. Through failure form analysis, the relationship between the interlock Tu and the neck thickness Tn of the joint with the best comprehensive mechanical properties was established: Tu = 0.35Tn. The design method of die and process parameters when the sheet thickness changes was researched by numerical simulation. The results show that the clearance between the punch and die, bottom thickness are directly proportional to the sheet thickness, and the drawing depth is directly proportional to the punch radius.
Quantitative Investigation on Localized Deformation Process of Rocks by Uniaxial Test and Digital Image Correlation
Authors: Zhu Ling , Cui Shenghua , Pei Xiangjun , Luo Luguang , Cheng Jianlong , Wang Hui , Du Ruifeng , Yang Qingwen 
Published: June 2022

Abstract
The uniaxial monotonic and cyclic loading tests were carried out. The acoustic emission (AE) events and surface deformation images in the loading process were obtained using the AE system and digital image correlation (DIC). The variance of the deformation field was introduced to reveal the formation and evolution processes of the localized deformation. The results show that the variance begins to increase significantly in the initiation of the macro-scale failure stage, and it increases sharply under cyclic loading before failure. The shape of the stress-variance hysteresis curve varies with increasing upper limit stress, and four types of stress-variance hysteresis curves were revealed. The damage variables are respectively defined by cumulative AE counts and variance, and the evolution process of damage variable can be divided into crack closure stage, initial damage stage, stable development stage, accelerated development stage and failure stage. By proposing the differentiation rate, it is found that there are apparent failure precursor points under monotonic and cyclic loading.

Abstract
New insecticides have recently been produced to help control pyrethroid-resistant malaria vectors including the pyrrole chlorfenapyr. Monitoring the susceptibility of mosquito populations against novel insecticides and potential cross-resistance with current insecticides is vital for better resistance management. In this study, we assessed the resistance status of the major malaria vectors Anopheles gambiae and Anopheles funestus to chlorfenapyr across Africa and explored potential cross-resistance with known pyrethroid resistance markers.Efficacy of chlorfenapyr 100µg/ml against An. gambiae and An. funestus from five Cameroonian locations, the Democratic Republic of Congo, Ghana, Uganda, and Malawi was assessed using CDC bottle assays. Synergist assays were performed with PBO (4%), DEM (8%) and DEF (0.25% and several pyrethroid-resistant markers were genotyped in both species to assess potential cross-resistance between pyrethroids and chlorfenapyr.Resistance to chlorfenapyr was detected in An. gambiae populations from DRC (Kinshasa) (mortality rate: 64.3 ± 7.1%) Ghana (Obuasi)(65.9 ± 7.4%), Cameroon (Mangoum ;75.2±7.7% and Nkolondom ; 86.1 ± 7.4). In contrast, all An. funestus populations were fully susceptible. A negative association was observed between the L1014F-kdr mutation and chlorfenapyr resistance with a greater frequency of homozygote resistant mosquitoes among the dead mosquitoes after exposure compared to alive (OR=0.5; P=0.02). No association was found between GSTe2 (I114T in An. gambiae; L119F in An. funestus) and resistance to chlorfenapyr. A significant increase of mortality to chlorfenapyr 10µg/ml was observed in An funestus after to PBO, DEM and DEF whereas decreased mortality was observed in An gambiae after pre-exposure to PBO although not significant.This study reveals a greater risk of chlorfenapyr resistance in An. gambiae populations than in An. funestus. However, the higher susceptibility in kdr-resistant mosquitoes points to the efficacy of chlorfenapyr against the widespread kdr-based pyrethroid resistance.

Published: June 2022

Abstract
Background: To evaluate the efficacy of the GLadIus MG drilLINg technique (GLIMGLIN), a novel initial wiring technique using the Gladius MGTM structural features, for crossing the superficial femoral artery (SFA) with chronic total occlusion (CTO). Methods: This retrospective, single-center study enrolled 27 symptomatic patients (mean age 77.4±8.5 years; 20 men) with de novo SFA CTO (mean CTO length 16.1±8.9 cm) who underwent GLIMGLIN as the initial wiring between January 2020 and December 2021. The success of GLIMGLIN was defined when the wire crossing was completed using a Gladius MGTM and a microcatheter without any additional devices. GLIMGLIN was defined as one of the conventional wiring techniques.Results: The success rates of GLIMGLIN and conventional wiring were 48.1% and 74.1%, respectively. Intravascular ultrasound findings showed complete true lumen passage in the GLIMGLIN success group. Compared to the failure group, the proximal (6.3±0.8 vs. 5.5±0.9 mm, p=0.02) and distal (5.9±0.5 vs. 5.4±0.6 mm, p=0.02) reference vessel diameters were significantly larger, and the rate of calcium angle >180° was significantly fewer (30.8 vs. 71.4 %, p=0.04) in the success group. No significant difference was shown in the CTO length between the group. Total wiring time, total procedure time, and fluoroscopic time were significantly shorter in the success group. Conclusions: GLIMGLIN may enable operators to perform CTO wiring easily, efficiently, and at a lower cost in selected cases.

Published: June 2022

Abstract
A series of thermotropic liquid crystal copolyesters (Co-TLCPs) was prepared by melt polymerization using 2,5-diethoxyterephthalic acid (DTA), 2,7-dihydroxynaphthalene (DHN), and p-hydroxybenzoic acid (HBA) monomers, where the HBA content was varied (0–5 mol). At 3 mol HBA, the Co-TLCPs formed nematic mesophases, while below this concentration, the liquid crystalline phase did not appear. The Co-TLCP sample with 3 mol HBA was subjected to melt spinning and heat-treated under various conditions (temperature and time) to investigate their effect on the thermo-mechanical properties and degree of crystallinity. The objective was to determine the critical heat treatment condition that can maximize the properties of the spun Co-TLCP fibers. The microstructure of the heat-treated fiber was investigated using scanning electron microscopy, and the optimal annealing conditions were confirmed based on the morphology of the fiber, which exhibited a skin–core structure owing to the varying heat and pressure conditions applied during spinning.
Genetic labeling reveals cellular expression pattern of neuregulin 1 in mouse forebrain

Published: June 2022

Abstract
Neuregulin 1 (Nrg1) encodes a neurotrophic factor and is genetically associated with schizophrenia, bipolar disorder and major depression. NRG1 has been shown to play important roles in neurodevelopment and neurotransmission. However, the knowledge about the cellular expression pattern of Nrg1 in mouse forebrain remains controversial and inconclusive. Here we used CRISPR/Cas9 techniques to generate Nrg1Cre/+ knockin mice which express the Cre recombinase immediately before the stop codon of Nrg1 gene. By crossing the Nrg1Cre/+ mice with Ai14 reporter mice which express fluorescent protein tdTomato in a Cre-dependent manner, we generated Nrg1 reporter mice which express tdTomato in cells where Nrg1 gene is actively transcribed. Using fluorescence imaging and unbiased stereology, we revealed the cellular expression pattern of Nrg1 in mouse forebrain regions including the olfactory bulb, cerebral cortex, striatum and hippocampus. We further performed stereotaxic injection of adeno-associated virus (AAV) which express tdTomato in a Cre-dependent way into different forebrain regions of adult Nrg1Cre/+ mice, and thus explored the distribution and axon projection of Nrg1-positive cells. These results provide fundamental information needed for the study of Nrg1 function in mouse forebrain. Moreover, the Nrg1Cre/+ mice generated here may represent a useful tool to study the function of neuronal populations expressing Nrg1.

Published: June 2022

Abstract
The current study proposed a novel and improved cigarette filtration design comprising cellulose nanofibers (CNF) and powdered activated carbons (PAC) with different dry matter contents. The proposed filter samples were primarily analyzed to verify their applicability as a cigarette filter via several measurements and standard tests, such as SEM, BET, DSC, and airflow permeability analysis and obtained results were compared with cellulose acetate (CA) sample which is used as a conventional filter in cigarettes. The preliminary results indicated noticeable improvement compared to the reference CA. Also, The cigarettes were tested using a smoking machine and the filtered smoke was analyzed using GC-MS to evaluate the performances of the filters in reducing the main harmful substances present in smoke. The obtained result showed that the filters made of CNF and PAC significantly reduced the hurmful substances in comparison with reference but do not significantly affect the nicotine and therefore will not negatively impact the trance level of smokers.

Published: June 2022

Abstract
In this work, we propose a surface plasmon resonance (SPR) biosensor based on a hybrid structure of silicon nitride (Si3N4), molybdenum trioxide (MoO3), and graphene oxide (GO) in the Kretschmann configuration. In order to investigate the performance parameter of the SPR biosensor, we calculate, theoretically, the reflectance spectra of the proposed model and analysed it. The investigation of various performance parameters i.e., sensitivity, detection accuracy, and quality factor, of sensor configuration are theoretically done with the optimized thickness of silver (55 nm), silicon nitride (5 nm), molybdenum trioxide (10 nm), and graphene oxide (2.55 nm) respectively. The sensitivity, detection accuracy, and figure of merit for the proposed SPR structure is found at 301 deg./RIU, 4.01, and 133 RIU-1 respectively for the detection of IgG. It is clearly observed that the sensitivity of the proposed biosensor is enhanced by 43.2% with respect to other conventional SPR biosensors. The refractive index of the analyte changes from 1.33 to 1.37 due to adsorption of the analyte at the GO surface. The proposed sensor design is able to detect the small change in the refractive index of the sensing media doped with the analyte. Therefore, the proposed structure of the SPR sensor may have potential applications in the field of biomedical and chemical sensing applications.
