Published: June 2022

Abstract
Linkage mapping is an approach to order markers based on recombination events. Mapping algorithms cannot easily handle genotyping errors, which are common in high-throughput genotyping data. To solve this issue, strategies have been developed, aimed mostly at identifying and eliminating these errors. One such strategy is SMOOTH (van Os et al. 2005), an iterative algorithm to detect genotyping errors. Unlike other approaches, SMOOTH can also be used to impute the most probable alternative genotypes, but its application is limited to diploid species and to markers heterozygous in only one of the parents. In this study we adapted SMOOTH to expand its use to any marker type and to autopolyploids with the use of identity-by-descent probabilities, naming the updated algorithm Smooth Descent (SD). We applied SD to real and simulated data, showing that in the presence of genotyping errors this method produces better genetic maps in terms of marker order and map length. SD is particularly useful for error rates between 5% and 20% and when error rates are not homogeneous among markers or individuals. With a starting error rate of 10%, SD reduced it to ~ 5% in diploids, ~ 7% in tetraploids and ~ 8.5% in hexaploids. Conversely, the correlation between true and estimated genetic maps increased by 0.03 in tetraploids and by 0.2 in hexaploids, while worsening slightly in diploids (~ 0.0015). We also show that the combination of genotype curation and map re-estimation allowed us to obtain better genetic maps while correcting wrong genotypes. We have implemented this algorithm in the R package SmoothDescent.

Abstract
As the immunity gained by primary immunization against COVID-19 decreases over time, health authorities all over the world currently recommend a 3rd booster vaccination. We present the case of a young healthy man who received two primary doses of Comirnaty that were well tolerated, but developed an acute infarct-like myocarditis following his heterologous booster vaccination with Spikevax. Cardiovascular magnetic resonance (CMR) imaging revealed a severe non-ischemic pattern of acute myocardial inflammation. We suggest to act with caution when selecting the booster vaccine and to avoid a heterologous booster with Spikevax – if possible – particularly in young males.

Abstract
The quality control of the bacterial cellulose (BC) production has been facing challenges due to the genetic stability of bacterial strains, which is often overlooked or underestimated. Thus, its commercialized application is limited. Therefore, a bacterial strain FM883 with a 16S rRNA sequence 97% identical to Komagataeibacter xylinus NBRC15237T was isolated from kombucha tea. Cultivation of FM883 was conducted in series to observe the morphology and BC yield among different generations from 1st generation to 30th generation. The results show that FM883 can efficiently produce BC in modified Hestrin-Schramn media at the 30th generation (163.5 ± 0.3 g/L), which was even higher than the 1st generation (157.6 ± 0.3 g/L). This indicated that FM883 has strong genetic stability. Furthermore, several characterizations of the BC indicated that the quality of the BC biosynthesized by FM883 was good with excellent thermostability. With such strong genetic stability, properties, sufficiently high consistency and high yield, BC biosynthesized by FM883 had demonstrated excellent production quality control, which is desired for commercial manufacturing.

Abstract
Formation of chlorate (ClO3−) and perchlorate (ClO4−) as by-products in electrooxidation process has raised concern. In the present study, the formation of ClO3− and ClO4− in the presence of 1.0 mM Cl− on boron doped diamond (BDD) and Magneli phase titanium suboxide (Ti4O7) anodes were evaluated. The Cl− was transformed to ClO3− (temporal maximum 276.2 µM) in the first 0.5 h on BDD anodes with a constant current density of 10 mA cm2, while approximately 1000 µM ClO4− was formed after 4.0 h. The formation of ClO3− on the Ti4O7 anode was slower, reaching a temporary maximum of approximately 350.6 µM in 4.0 h, and the formation of ClO4− was also slower on the Ti4O7 anode, taking 8.0 h to reach 780.0 µM. Compared with the BDD anode, the rate of ClO3− and ClO4− formation on the Ti4O7 anode were always slower, regardless of the supporting electrolytes used in the experiments, including Na2SO4, NaNO3, Na2B4O7, and Na2HPO4. It is interesting that the formation of ClO4− during electrooxidation was largely mitigated or even eliminated, when methanol, KI, and H2O2 were included in the reaction solutions. The mechanism of the inhibition on Cl− transformation by electrooxidation was explored.
WITHDRAWN: Study on the effect of initial rainwater pollution and the influence of concentrated infiltration on soil—Take Xi’an, Northwest China for Example

Published: June 2022

Abstract
The initial rain water carries a large amount of pollutants. It is easy to cause urban non-point source pollution. Obtaining the initial rainwater pollutants concentration is an important basis for controlling urban non-point source pollution. 38 and 46 rainfall events are conducted from March 2016 to September 2021 to study the pollutants concentration of initial rainwater from roof and road in Xi’an, and to determine the initial abandoned flow, then to analyze the influences of stormwater concentration infiltration in rain gardens on soil. The results show that the road runoff pollutants concentration is significantly bigger than those of the roofs, and both inferior to the "Surface Water Environmental Quality Standard" (GB3838-2002) of Ⅴcategory. The concentration of COD, ammonium nitrogen(NH4+-N), nitrate nitrogen(NO3--N), total nitrogen(TN), total phosphorus(TP) and heavy metal of Zn of road runoff are 2.53, 1.85, 2.35, 1.89, 3.91 and 6.61 times bigger than those of the roofs. The pollutants concentration of road and roof runoff is decreasing gradually with the monitoring time. (2) For road runoff, the initial abandonment rain water is recommended to adopt the runoff within 10~15 min, however, for the roof runoff, it is recommended to adopt the runoff within 8~10 min. (3) The concentrated infiltration of rainfall runoff has a great effect on the surface soil of rain garden. The NH4+-N, TN and heavy metals of Zn, Cd and Pb within the 0~30cm soil are significantly bigger than those in the lower layer, but TP and NO3--N migrate downward with water infiltration. The results indicate that the stormwater concentration infiltration has the risk of N, P and heavy metal pollution to the soil in the rain gardens.

Abstract
Herein, a series of covalent triazine framework/bismuth vanadate (CTF/BiVO4) heterojunction catalysts was prepared using the hydrothermal method. The mechanism of the CTF/BiVO4 heterojunction photocatalyst in the system was examined to provide a theoretical basis for constructing a high-efficiency adsorption–photocatalysis dual-function composite system for removing the organic pollutants in water. Compared with single CTF and BiVO4 catalysts, some studies have shown that composite materials have significantly higher degradation efficiencies against organic pollutants in water. Moreover, degradation effect is optimal when the mass ratio of CTF to BiVO4 is 1:1 (1-CTF/BiVO4). Through characterization methods, such as XRD, SEM, FTIR, and XPS, it was concluded that the effective construction of CTF/BiVO4 composite photocatalyst material systems and the formation of type II heterojunction structures between CTF and BiVO4 effectively promote the separation of photogenerated carriers and increase the interface charge transfer efficiency.

Abstract
The study and measurement of elemental compositions of historical pottery have particular importance. Only by knowing the elemental composition of these historical artifacts can precious information be obtained in various fields such as technology and manufacturing technique, determination of raw materials used in manufacturing and their diversity, the study of trade and exchange, and provenance study of these historical objects. In this article, 14 pieces of glazed artifacts, including the remaining nine dishes and five tiles belonging to the middle of the Islamic period, have been analyzed and examined using the micro-PIXE technique.The pottery studied in this article have been obtained from the second season of archaeological excavation in the ancient site of Kohneh Gorab Amlash in Gilan province in 2021. In the present study, the elemental compositions of the main body, the base glaze, and the surface decorations used in these pieces have been measured using the micro-PIXE analysis for the first time.This study uses elemental analysis to find appropriate answers to related questions. What raw materials have been used to manufacture the main body and glaze of these objects, whether the same raw materials used in the main body and base glaze? What is the resource of the raw materials used as flux or melting materials? Determining the colorant agents and identifying the elements that are responsible for different colors is another question that can be considered as another goal of this research work.Based on the results obtained from the elemental compositions of the main body of the pottery, it can be concluded that different sources of silica have been used in the making of the pottery of Kohneh Gorab Amlash. Elemental analysis depicted three different types of raw materials used in the main body of this pottery to supply silica raw materials. The first group used stonepaste as silica raw materials, and the second and third groups were used clay to silica resources. Also, the results of elemental analysis of the base glaze show that three types of alkali glaze, lead glaze and lead-tin-alkali glaze, can be identified in these studied objects. In addition, the results shows that the flux used in alkaline glazes was prepared from plant ashes.

Published: June 2022

Abstract
A study was conducted with the objective of evaluating the in-vivo acaricidal efficacy of Tephrosia vogelii leaf extract in controlling ticks on cattle. For this experiment, forty five naturally tick infested cattle were selected and equally divided into five treatment groups of nine animals in completely randomized design. The first three groups were topically treated with 20%, 25% and 30% w/v extract, the forth group was sprayed with diazinon as positive control at a recommended dose of 1:1000 while the fifth group was left untreated as negative control. Tick counts were conducted on day0 pre-treatment and on days4 and 7 post treatment on each animal. Post-treatment quantitative assessment of tick burden revealed a significant (P < 0.05) reduction in tick load in all treated groups compared to untreated ones. The percentage tick count reduction was higher at day 7 than day 4 for all treated groups with their respective efficacy of 80.33%, 85.42% and 90% for 20%, 25% and 30% extracts and 97.67% for diazinon at day 7 post treatment. The observed tick count reductions were found to be statistically significant (P < 0.05) at all dilution levels of the extract but without significant difference (P > 0.05) among themselves. The results also revealed both time and dose dependent efficacy of the extract and its comparable effectiveness with diazinon which was an evidence suggestive of its significant anti-tick effect. Therefore Tephrosia vogelii could be recommended as effective natural tick control alternative, especially for poorly-resourced small-scale farmers in rural areas where commercial acaricides are unavailable or unaffordable.
Aerodynamic analysis of autonomous battery electric truck concepts for drag reduction
Authors: Anirood Kameel , Rugbani Ali 
Published: June 2022

Abstract
This research presents an aerodynamic drag analysis of an autonomous battery electric truck (BET) by means of using computational fluid dynamics (CFD) as a simulation tool. The CFD simulation utilises the Reynolds-averaged Navier–Stokes (RANS) equations with a realizable k-𝜀 turbulence model and non-equilibrium wall functions to model the near-wall region of the domain. The simulation accuracy is validated against empirical results for the aerodynamic drag on the generic conventional model (GCM) truck, as tested in a wind tunnel. It was found that the overall aerodynamic drag of the vehicle could be reduced by approximately 35.5% without reducing the truck’s trailer loading volume. This work demonstrates that autonomous BETs can significantly reduce the overall aerodynamic drag of a truck, thereby reducing energy consumption and greenhouse gas (GHG) emissions for the land freight sector.

Published: June 2022

Abstract
Salicylic acid (SA) was sprayed on tea seedlings to evaluate its effect on resistance to root rot and the quality of tea. Results showed that disease resistance was enhanced by spreading exogenous SA. Tea production was improved in SA treatment. Further studies showed that SA improves tea plant disease resistance by inducing polyphenol oxidases and lipoxygenase. SA treatment significantly increased the contents of polyphenols, namely catechins and flavonoids, which are the main tea quality parameters. Salicylic acid spraying could enhance the resistance of tea plants to diseases and improve the production and quality of tea.

Abstract

Dielectric elastomers (DE) containing conducting inorganic fillers would have great potential for actuators, capacitive energy storage, elastomer sensors and many other applications. In this regard, ternary composites with metal alloy materials as reinforcing fillers might be an enabler for low dielectric loss and high dielectric constant. Herein, ternary rubber composites were prepared by incorporation of Cu-based alloy into acrylonitrile-butadiene rubbers (NBR). However, material incompatibility between the Cu-Al-Zn alloy and the rubber matrix often results in phase separation, void formation and particle aggregation, with dramatically degraded performance. Through surface modification, Cu-Al-Zn alloy particles were uniformly dispersed onto the NBR rubber matrix via 3-(Trimethoxysilyl) propyl methacrylate (TMSPM) as coupling agent. The effective reinforcement of modified Cu-based alloy particles into NBR was systematically analyzed by SEM (scanning electron microscope) and XRD (X-ray diffraction). The results reveal that the morphology and dispersion state of modified Cu-Al-Zn alloy were critical to the dielectric properties of the NBR compounds. Mechanical properties were greatly enhanced by the reinforcement of modified Cu-based alloy into the NBR matrix. The outstanding performance of NBR composites is due to the uniform dispersion of modified Cu-Al-Zn alloy particles and good interfacial compatibility with rubber matrix, suggesting high performance dielectric composite.

Published: June 2022

Abstract
The construction of information infrastructure as well as the transformation and upgrading of the industrial structure are among the major challenges facing China's economy nowadays. Therefore, it is of great significance to explore how information infrastructure affects the upgrading of industrial structure. Based on the panel data of 31 provinces in China from 2013 to 2020, mediating effect model and non-parametric percentile bootstrap method are used to carry out empirical research, by creating an information infrastructure construction level and industrial structure upgrading indicators. The results show that, in addition to the direct effect of information infrastructure on industrial structure upgrading, information infrastructure can also work indirectly through three paths: (1) information infrastructure acts on industrial structure upgrading by enhancing urbanization level; (2) information infrastructure affects industrial structure upgrading by boosting technological progress; (3) information infrastructure first enhances urbanization level, then acts on technological progress, and finally promotes industrial structure upgrading. In addition, the intermediary effect of technological progress is stronger than urbanization. In general, this study acknowledges that urbanization and technological progress are partial mediators in the process of information infrastructure affecting industrial structure upgrading, notwithstanding other potential impact pathways being studied further.

Abstract
Post-Acute COVID-19 syndrome (PACS) is considered to be one of the least understood post-infectious syndromes. We report a case of a 21-year-old female who had a history of SARS-CoV-2 infection and presented with a right atrioventricular thrombus associated with pulmonary embolism and thrombocytopenia. At the time of admission, she was not vaccinated against SARS-CoV-2, and her serological tests for IgG and IgM antibodies against SARS-CoV-2 were positive. The size of the thrombus measured approximately 6×8×4 cm, which also led to tricuspid valve insufficiency due to mechanical dilatation of the valve’s ring. The right atrioventricular thrombus also extended up to the inferior vena cava, leading to mild congestive hepatomegaly. Moreover, during thrombectomy, the mass of the thrombus was attached to the interseptal right atrial wall. The histopathological assessment of the core mass revealed that it was a right atrial myxoma hidden inside that large thrombus. We suspect that the formation and propagation of the thrombus to that size occurs as a part of Post-Acute COVID-19 syndrome (PACS). This study reviews and discusses coronavirus disease 2019-relate to thrombus formation inside cardiac chambers in case of a cardiac tumor, like myxoma in the setting of post-acute phase COVID-19 syndrome.
A case of intestinal obstruction in a middle aged woman – a pathological surprise
Authors: Ng Chi Sing , Kwok Derek YS , Cheuk Wah 
Published: June 2022

Abstract
Background:Fibromatosis is a tumour of fibroblasts and myofibroblasts with a tendency of local invasion and recurrence but no malignant potential and is classified as superficial or deep. Intra-abdominal fibrosis, a type of deep fibromatosis, is a rare cause of intestinal obstruction. We report intestinal obstruction in a middle aged woman caused by jejunal/mesenteric fibromatosis.Case presentation:An early 40s woman presented with intestinal obstruction and a month-long history of abdominal pain. She required emergency surgical intervention which uncovered an obstructive mass involving the jejunum and adjacent mesentery. Histology of the resected tumor with wide surgical margins revealed fibromatosis with positive nuclear â-catenin immunohistochemistry.Conclusion:Fibromatosis is a rare cause of intestinal obstruction. Awareness of the condition and recognition of the myriad histological features is important for accurate diagnosis and distinction from its mimickers. Positive nuclear staining of tumour cells for â-catenin is an important clue to diagnosis. Distinction from other causes of intestinal obstruction is paramount for implications on different modalities of management and prognosis.

Published: June 2022

Abstract
Background
Clinically overt contrast-induced nephropathy (CIN) is one of the most feared complications in patients exposed to iodinated contrast media and has been extensively studied over the years. Meanwhile, the incidence and evolution of subclinical contrast-induced kidney injury remain elusive. With the continuous increase in the number of patients that are repeatedly exposed to contrast media, elucidating these issues is of critical importance. Accordingly, we aimed to evaluate the incidence and the evolution of clinical and subclinical kidney injury in patients exposed to contrast media.
Methods
A total of 178 patients who underwent elective percutaneous angioplasty procedures were evaluated prospectively. Serum creatinine and neutrophil gelatinase-associated lipocalin (NGAL) levels were evaluated pre-procedurally, 48 hours and 1 month after administration of contrast media. The evolution of creatinine and NGAL levels was analyzed at the three time points, and the potential predictors of contrast-induced clinical and subclinical renal injury were evaluated.
Results
Clinically overt CIN occurred in 10 (5.6%) patients. Baseline serum creatinine and the volume of contrast media were the only independent predictors of CIN and in all 10 patients creatinine levels returned to baseline by 1 month (p = 0.32). Subclinical contrast-induced kidney injury was much more common, affecting 32 (17.9%) patients, was only predicted by the baseline serum creatinine, and persisted in 53.1% of patients after one month.
Conclusions
This study showed that whereas clinically overt CIN is rather rare and regressive, subclinical contrast-induced kidney injury is considerably more frequent, affecting almost 18% of patients that receive intraarterial contrast media. More importantly, subclinical kidney injury persisted after 1 month in more than 50% of the initially affected patients, who may thus be at increased risk for further renal impairment, particularly if exposed to nephrotoxic agents or repeated administration of contrast media.
